Introduction

This project was developed on the basis of the assignment of the Department of Architecture. A production building was designed - a workshop for the production of reinforced concrete structures.

The proposed construction site is Pskov. According to the task, the soil at the construction site is loam, the terrain is calm, the depth of groundwater is 3.0 m.

Materials used:

foundations - prefabricated and prefabricated reinforced concrete;

frame - precast reinforced concrete and metal;

walls - "railway panel";

coating - precast reinforced concrete, metal trusses.

In terms of explosion and fire hazard, the workshop building corresponds to category "D."

Production technology

The space-planning solution of any industrial building depends on the nature of the technological process located in the building.

The technological process in turn is predetermined by the production and technological scheme, in which a certain sequence of operations for the production of products or semi-finished products is established, the technological equipment and the nature of its arrangement, the type and carrying capacity of internal transport, nomenclature, size and sequence of rooms arrangement, internal temperature and humidity regime, etc. The process diagram also provides for the places of raw materials and auxiliary materials receipt, output of finished products or semi-finished products, removal of production wastes, place of commissioning of engineering networks.

To ensure rational layout of workshops, it is necessary to know the dimensions of technological equipment and finished products, the nature of the location of workplaces, the width of passages and driveways, as well as the layout of production equipment.

The complex of planning issues of the building includes ensuring its good performance, which largely depends on the placement of individual production sites. So, wet process compartments should be located in the middle part of the building. You should also place compartments with a strictly specified temperature and humidity regime. Areas with hot processes are located near external walls.

For the Instrument Manufacturing Plant Tool and Stamping Shop to be designed, a process diagram is used with sequential promotion of products in the shop areas.

Plot Planning Scheme

The designed workshop is supposed to be located in the city of Pskov. The designed mechanical workshop of the instrument-making plant is part of an industrial enterprise and is located in the western part of the plant in the production zone. The site is designed on a site with located on the territory of the quarter. All of them are served by road.

The mechanical workshop of the instrument making plant belongs to category "D" in terms of fire hazard and will be located in the production area of ​ ​ the enterprise from the windward side in relation to other workshops included in this production quarter.

Also, given the direction of the prevailing northwest winds, the workshop should be located so that people working in it are least exposed to the harmful effects of released substances during production. The distances between the buildings of the production area are taken in accordance with the degree of fire resistance and the fire hazard category of the workshops.

The width of the driveways is adopted taking into account the observance of sanitary and fire breaks of the principles of zoning and modular coordination. The production building provides for the entry of forklifts and biaxial vehicles. The width of the carriageway of the main highways is designed to be 9 m, for entrances - 6.0 m. Radii at the intersections of main roads are taken to be 12 m. The width of the gate of road entrances is taken to be 4 m. Three entrances are designed in the building. The pavement of the roads is designed asphalt. It is assumed that the approach of people to the workshop will be carried out along sidewalks, the width of which is 1.5 m, depending on the number of workers moving along them.

On the territory of the production zone, an administrative building, a platform for physical exercises were designed. culture. The sites will be located on the windward side in relation to the respective workshops.

Surface drainage from coatings is provided.

The vertical layout preserves the existing terrain by creating slopes > = 0.003. An asphalt - concrete pavement 2.0 m wide is arranged around the building. The elevation of the planned ground surface at the workshop is 103.15 m. The absolute elevation of the floor of the workshop is taken as a relative elevation of 0.000.

4. Space Planning Solution

The mechanical workshop of the mechanical engineering plant is designed in a three-span plan with two spans in a reinforced concrete frame and one in a steel frame. Two spans in a reinforced concrete frame and a span in a metal frame are located perpendicular to each other. The total dimensions of the workshop in the axes "AE" are 120.0 m, "111" - 10800 m. Spans in reinforced concrete frames are 24 m, in steel - 36 m. The height from the level of the clean floor of the workshop to the bottom of the rafters is 14.4 m in the steel frame and 9.6 m in reinforced concrete. The pitch of the columns in the reinforced concrete and metal frames is 12 m. The size of the insert "c" between the reinforced concrete and steel frames is 750 mm. The binding of reinforced concrete and metal columns to the longitudinal axes of the building (axes "A," "e") is 600 mm. The binding of the reinforced concrete columns (in the perpendicular reinforced concrete frame) to the transverse axes of the building (axis "1," "11") is 600 mm. Binding of columns in reinforced concrete frame to longitudinal axes (axis "E") - "zero." The binding of the columns of the metal frame to the transverse axes of the frame (axis "1," "6") is 250 mm.

Within two spans of the reinforced concrete frame, the action of the crane-beam with a lifting capacity of 10 tons, the span of the steel frame - the bridge crane with a lifting capacity of 20 tons is assumed.

The location of all sections is designed in accordance with functional and sanitary requirements. Sound insulation of the walls of plenum and exhaust ventilation chambers is provided.

Evacuation exits from the workshop are designed through entrances to the swing gates, 4.0 m wide, which are supposed to be located: one entrance - at the end and one - at the side of the steel frame, one entrance - at the rear of the reinforced concrete frame. Gate is provided with gate arrangement. The aeration action is carried out due to the difference in the specific weights of the external and internal air, that is, the desire of the heated and lighter air to enter the highly located exhaust holes, and the colder one to enter the room through the low located plenum holes. To ensure aeration in the designed building, windows located at different levels are used, as well as 2 light-aeration lights, which are designed in the spans of the reinforced concrete frame.

An administrative building is attached to the transverse wall of the production building along the axis "3." The grid cell of the columns is 12x12 m, the dimensions of the ABK in the axes 12x54 m, the height of the floor is 3.6 m. The ABK building is two-story. There is no basement and technical floor .

Architectural and structural solution

In accordance with the operating conditions of the building, we accept the following structures:

5.1. Foundations, foundation beams

The foundations for the columns are designed monolithic reinforced concrete columnar with a three-stage slab part according to the 1.412 series. For reinforced concrete frames, we accept the foundations of the following grades: for the main columns - FV111 2.4 m high, for the front columns (end columns) of the reinforced concrete frame - FB101 1.8 m high. For the main columns of the steel frame, we accept foundations 2.85 m high with a sub-column area of ​ ​ 1.8 × 1.2 m, the first sole stage - 4.2 × 3.6 m, the second - 3.0 × 1.2 m, the third. For floor columns of a steel frame, we accept foundations with a height of 2.1 m with a sub-column with an area of ​ ​ 1.8 × 1.2 m, a sole stage - 2.4 × 2.1 m.

We project foundation beams on KE0123 series for reinforced concrete and steel frameworks for a step of 6 m 400 mm high and 4950 mm long .

The cut of the foundations is located at an elevation of 0.15 m.

When opening the base, the solid soil directly receiving the load is leveled and concrete preparation with a thickness of 100 mm from concrete M 75 is carried out. Foundation floor is mounted on concrete preparation. The gap between the faces of the columns and the walls of the sleeve is 75 mm at the top and 50 mm at the bottom, and 50 mm between the bottom of the columns and the bottom of the sleeve. Pouring of cups after installation of columns is performed with concrete M 200 on fine gravel.

Section of sub-columns for bases of steel columns is selected based on arrangement of anchor bolts so that distance from bolt axis to edge of sub-column is not less than 150 mm. When resting steel columns on the concrete foundation, it is provided to gravel the base slab with cement mortar M 400. Holes are provided in traverses for rainwater runoff falling on the base plate during installation of the building.

To support foundation beams, it is recommended to arrange gravels with a section area of ​ ​ 0.3 × 0.6 m with a cut at an elevation of 0.45 m (at a beam height of 0.4 m, for the pitch of columns of 6 m).

5.2 Columns

Columns of rectangular reinforced concrete frames in buildings with crane beams for a pitch of 12 m are accepted according to the KP121 series. In the row, connecting columns are separated, connected by steel vertical links for perception of horizontal forces. Embedded elements are available in all columns in the places of support of rafters and crane beams, at the level of seams of wall panels, in linked columns - at the places of adjoining longitudinal links. To connect to the foundation, the column is brought into the sleeve to a depth of 0.85 m with a rectangular section. Within these limits, the column shaft is provided with horizontal grooves to communicate with the grouting concrete. All columns of reinforced concrete frames are accepted with a height of 9.6 m.

The columns of the steel frame take two-branch with a passage along the series 1.4244, made of rolling wide-beam I-beams and bent channels with parallel faces of the shelves. The height of these columns is 14.4 m.

The width of the columns is 2000 mm. The section height of the column branches is assumed to be 400 mm. The pitch of the braces is 900 mm. The two-wind stepped column consists of a lower (crane) lattice and an upper (over-crane) - of welded I-beam. The crane part of the column goes to the base directly supported by the concrete foundation. The base consists of a base plate and crossbars, on which tiles with anchor bolts recessed in concrete lie. In interconnected columns, the support plate is additionally welded to shorts from channels embedded in the foundation. The grid of the crane part of the column is double-plane, from rolling angles. To perceive moments acting in the horizontal plane, the lattice part is strengthened by diaphragms located at least through four braces in height. In the lattice part of the column of the extreme row, in the level of attachment of the support cantilevers of the tier of wall panels, a beam is welded from a rolling I-beam connecting the external and crane branches. The lattice part of the column is completed by a single-plane traverse connecting its branches with the above-crane part. The over-crane part of the column is completed with a head reinforced with additional ribs and straps. Additional ribs and straps are located in plane of support ribs of rafters. Welding of I-beams from three sheets for the main sections of the column is carried out in factory conditions by welding machines. Welding of other elements of columns will be performed using welding semi-automatic machines. Manual welding is used in units mounted on the construction site. Bent channels for external branches of the column are manufactured on bending presses in factory conditions. In the base, crane support and head - places of transfer of significant concentrated loads, vertical elements with their section should be tightly adjacent to the support plates. For this purpose, the edges of the separately mounted sheets are attached, and the section of the branches is milled. Column bases are covered with concrete at arrangement of underlying layer for floors. Columns shall be installed on steel slabs 60 mm thick, reinforced over foundations on bolts and cement mortar. The diameter of the anchor bolts is 36 mm. Mill the bottom ends of the column. The elements of the column are made of low-alloy steel 14G2. Load transfer to the column from split crane beams and rafter trusses is carried out in design planes through lapped support ribs, the position of which is fixed by installation bolts.

Columns of the end fuselage accept wind load and mass of panel walls. The heads of the headers are located on the same level as the heads of the main columns - 150 mm below the rafter truss belt. Within the height of the rafter truss, the faucet columns are built up with welded I-trays with a section height of 0.25 m. These extensions do not reach 0.3 m to the backfill and continue with nozzles from rolling corners within the height of the parapet. The flange of the nozzle corner is seamed vertically between the parapet panels. Thus, the end fuselage columns extend to the entire height of the end walls and do not intersect with the coating structures.

5.3 Rafter and Tuning Trusses

Rafter reinforced concrete raceless trusses with a slope of 5% are accepted for the grid of columns of the reinforced concrete frame 24 × 6 m grade FB2411. The slope of 5% is provided by horns extended from the upper belt. Before installation, support sheets are welded to support units of rafters. Mounting is performed on anchor bolts; the support sheets are then welded to the column heads. The general stability of the coating trusses during the operation of the building is provided by a hard disk of frozen flooring and bonds. Ribbed slabs constituting flooring are welded to embedded elements of upper girder belt at least at three points each.

In the steel frame we accept rafters of grade FS362.50 according to the series 1.460 - 4. The height of the trusses on the support along the sheaths of the belts is 3150 mm. The nominal length of trusses is 400 mm less than the span of the building due to the shortening of the extreme panels by 200 mm (29600mm). Support posts - from rolling I-beams with a height of 3300 mm. The section height of the extreme support posts is 200 mm + 250 mm (column reference value) = 450 mm. Rafters are designed from low alloy steel. All main rods of trusses are composed of paired hot-rolled corners connected in units by shapes. The thickness of the nodal chamfers is taken depending on the forces acting in the rods (from 8 to 20 mm). In the places of support of lattice runs, posts of lamp panels and in the joints of sending grades along the upper belt of rafters, 12 mm thick linings are welded. In place of perception of concentrated forces, sections of elements of columns and trusses are reinforced by additional ribs and straps. Most connections are made on black bolts followed by mounting welding. Fastening of runs to upper belt of rafter truss is fixed by supporting shorts from corners. In the extreme steps of the steel frame, adjusting trusses with a length of 12 m of PF1269 grade according to series 1 are installed. 4604.

5.4. Light-aeration canopy

Two canopies are designed in the span of the reinforced concrete frame with a width of 6 m. Lamps are provided for ventilation of rooms and for lighting. The canopy is located along the span axis and with its ends does not reach one step to the end of the building (i.e. by 6 m). The lights are a U-shaped superstructure above the opening in the roof. Vertical planes of the canopy above the side 0.6 m high from the roof level are filled with opening bindings. Canopy cover slope is 1.5%. Access to the canopy roof - by a special steel staircase located at the end. The canopy is used as an exhaust and plenum device. Rack-type mechanism for opening longitudinal bindings will operate in automatic mode from sensors installed in aeration openings. Closing the windward side, they ensure the blowability of the canopy. The main elements of the canopy frame are steel structures in the form of lantern panels, lantern trusses, end truss panels and lantern links. These designs are issued as separate shipping stamps. Lamp panels with bindings suspended on them form a light front. Light openings are limited from above by a binding channel, and from below - by a special bent profile of the canopy side. Vertical posts spacing is 3m. The lamp truss is built over the rafter truss, in its plane forms the crossbeam of the canopy. It consists of an upper belt, struts and braces. End truss-panel is reinforced by braces corresponding to trusses. Steel bindings of light-aeration lamps are accepted with a nominal length of 6 m and a height of 2.72 m with bindings and humps from hot-rolled profiles as per GOST 751173 "PP." In "PP" bindings with a muntins pitch of 0.6 m, the glass is edged with rubber profiles and pressed by means of clammers and bolts. Upper suspension bindings with hinges located inside the canopy. Brackets for suspension of bindings are attached on bolts to the lantern panel binding, and supports installed in them - to the upper binding of the binding frame. Bolted connections with oval holes allow you to adjust the suspension. Mating of lower binding of binding frame and side of lamp panel - overlapping by 20 mm. Sealing of the joint of blind and opening sections is performed in PP bindings - galvanized steel collectors. Canopy angles are filled with inserts made of galvanized steel. Safety of glass breakers is ensured by enclosing rods pushed through holes in posts of the lamp panel. Access from the roof to the opening mechanisms - through a glazed door unit with a side suspension. The glass opening is placed in place of one of the extreme glasses. The frame-revision along the perimeter is equipped with a ridge, which is brought in the same way as glass in the frame of the binding .

5.5. Crane beams

In the spans, the action of two crane beams with a lifting capacity of 10 tons is assumed. For a step of columns in a reinforced concrete framework, equal 6 m, we accept the subcrane beams of the tavrovy section 1000 mm high made of M500 brand concrete (on KE0150 series). The width of the upper shelf is 600 mm, the thickness is 120 mm. The section width at the bottom is 200 mm. Type of crane rail - KR70. The crane beam is attached to the column console on anchor bolts passed through the support sheet, previously welded to the lower embedded plate, and to the column neck - by welding the vertical sheet to the embedded plates. Bolted connections are brewed after straightening. The rail for the length of the temperature compartment is laid on an elastic gasket made of rubberized fabric with a thickness of 8 mm with a double-sided rubber lining and is fixed with paired tabs on screwed bolts. The joint of the rails above the deformation seam is crimped by steel linings of the shaped profile. To prevent possible ramming with an end wall crane, steel end stops are installed on the end beams to insure the building in case of failure of automatic braking devices. For cranes with a lifting capacity of 5 t and 10 t, which ≤ 30 t, they are of I-section with a buffer of bar.

5.6. Communications

In transverse direction stability of building is provided by stiffness of columns embedded in foundation and by rigid disk of coating, in longitudinal direction - additionally by steel bonds located in middle step of temperature compartment within height of crane part of columns. For a step of 6 m, cross ties are arranged, the links in the center of the temperature block are X-shaped. The link rods are designed from paired hot-rolled corners 110x8, welded with straps and knot shapes. Connections are bolted to embedded elements in steel articles with subsequent welding. The role of horizontal links along the upper belt of transverse trusses is performed by large-panel coating plates.

5.7. Windows

In accordance with wall panels, steel window panels are designed with nominal dimensions of 6 × 1.2 m along the facade. The load from the own mass of the window filling will be transmitted to the wall windowsill panel through rigid gaskets. Panels are divided into opening and deaf; both are double and single glazing. In both cases, single glazing is located on the outside. Panels consist of bearing frame made of cold-bent profiles connected by spot welding. Glazed frames welded from 45 × 45 × 3.8 mm tavriks are suspended from the frame in the opening panels. External upper and inner lower-lower frames are opened for ventilation of rooms. Frames are connected to each other by means of lever mechanism for joint opening. In the lower panels, opening will be carried out manually, in the upper panels - by an electric drive. Glasses edged with rubber profile are fixed in blind panels directly to the load-bearing frame with cold-bent staples on M 8 bolts; in opening panels - to frames with clammers on M 6 bolts (clammers - in 250 mm). Window panels are suspended from columns at fastening angles similar to those used for wall panels. Panels are connected to fastening angles by bolts M 12. At low ambient temperatures, steel panels may be cold bridges. Their freezing and the appearance of condensate are possible. To reduce these phenomena, the gaps between the wall panels are supposed to be filled with a warm solution.

5.8. Gates

The steel frame of the canvases (binding from channels, I-beams, braces from strip steel) is filled with plank fillets and glazed bindings. Bar-like bandages of fillets and bind boxes are assembled in the frame by sliding the sidewalls on the spikes laid in the top and bottom. The fillet consists of two rows of a wagon with a layer of antiseptic and pergamine-wrapped felt. In accordance with the dimensions of the gate, the height of the lower tier of the frame is taken to be 2.08 m. In order to prevent blowing along the contour of the collar frame, straps made of strip steel are welded to the frame, and the slots between the plowing webs and under them are closed with flexible aprons made of rubber and tarpaulin. The gate is equipped with a mechanical drive, a set of instruments for manual opening and a thermal curtain. Emergency switches de-energize the system in case of ingress of foreign body between webs and during the period of gate opening.

5.9. Floor

The structural solution of the floor is related to the specific purpose of the production room. In general, the floors of production buildings consist of a coating - an upper layer directly subjected to all operational effects, and an underlying layer that receives mainly vertical loads and transfers them to the base - soil in a natural state. For the designed workshop, a floor is provided on ground compacted with crushed stone, as a coating - asphalt concrete 50 mm thick.

For the construction of wall corners, optional angular blocks of 160-800 mm long are used. The height and thickness of the corner blocks correspond to the dimensions of the main panel. The lower panel of the first tier rests on the foundation beam along the layer of anti-capillary waterproofing from cement sand mortar. The height layout of the panels is designed so that the horizontal seam is located 0.6 m below the top of the column. This seam will separate the panels attached to the columns and to the coating structures. End wall panels will be attached to reinforced concrete fencer columns and end fencer posts located between the main columns and the wall. Filling of seams of panel walls is supposed to be carried out with elastic synthetic gaskets 80 mm wide and sealing mastic. The thickness of the seams is fixed by rigid gaskets 200 × 200 mm, placed at the edges of the panel. Synthetic materials and sealing mastic will compensate for possible alteration of inter-tiered joints.
