About Frames

The list of 298 people.

Number: men - 125, women - 84.

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

Master Plan

The assembly shop is located in Vyksa and is part of the mechanical engineering plant. The facilities of the production area include:

mechanical assembly workshop;

blacksmith and press shop;

mechanical repair shop;

foundry.

The assembly shop belongs to category "D" in terms of its fire hazard and will be located on the leeward side in relation to other workshops included in the production area. Also, taking into account the direction of the prevailing westerly winds, the workshop should be located so that the people working in it are least exposed to the harmful effects of released substances during the production process. Therefore, the direction of the flow of people to the administrative building attached to the workshop is western. Human flows are isolated from cargo. The route of people and cargo is taken as minimal. 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 production building provides for the entry of forklifts and biaxial vehicles. The width of the carriageway of the main highways is designed equal to 7 m, for passages and entrances - 4.5 m. Intra-plant roads are provided with one common carriageway. Radii at the crossings of main roads are taken equal to 12 m. Rounding radii at entrances - 9m. The width of the gate of car entrances is assumed to be 4.2m. Eight entrances were designed to the building along the entire perimeter. Fire passages will be provided on both sides of the designed workshop. The pavement of the roads is designed asphalt.

It is assumed that the approach of people to the workshop will be carried out along the sidewalks, the width of which, based on the number of workers employed in the largest shift, is 2 m. Lawns, as well as a recreation area, have been designed on the territory of the production zone. On the territory of the production zone, it is planned to plant hardwood trees of group planting and coniferous trees of group and ordinary planting, as well as shrubs of ordinary planting.

Surface drainage from coatings is provided.

Finishing of industrial building

Exterior decoration

To isolate the seams between the panels, fill them with synthetic sealing gaskets made of poroisole and UMS50 sealing mastic. Paint the facade with paint for external works with increased water resistance. The color of the paint is emerald green. Apply PF115 antiseptic enamel as per GOST 606576 to the gate webs made of rigid boards. Paint metal bindings with HV125 enamel according to FL03K primer in red. Fill the walls with bricks near the doors. Around the building, arrange asphalt pavement for concrete preparation with a width of 1 m.

Interior decoration

Perform brick insert sections with stitching. Do not plaster the places of walls with brickwork. Fill in joints between wall panels with concrete of class B12.5. In the walls of the production building, consisting of wall panels, it is provided (before painting with lime mortar) to mash the seams and irregularities (shells) of the surfaces with cement sand mortar. The surfaces of the walls near the workplaces are painted with oil paint in two times to a height of 1.8m, above 1.8m the wall is painted with lime mortar. The walls of warehouses (away from workplaces) are whitened with lime mortar from the floor level to the coating level. The ceilings are painted with lime mortar with preliminary mashing of the seams with cement sand mortar. Paint metal structures with HV125 enamel on FL03K primer in two times. Floor covering - concrete.

Finishing of auxiliary building

The decoration of the administrative building in this course project is not considered. The ABK building shall be attached with its long side (84m) to the long side of the reinforced concrete frame of the designed workshop. The width of the auxiliary building is 14 m. Its total area is 3880.8m2. The height of the floor is 3.3m.

Fire protection measures

The designed building of the workshop has a fire resistance degree of IIa. The mechanical assembly shop is enveloped on both sides by the main highway, and on the other two sides by a planned surface ensuring the passage of fire engines located at a distance of 10 m from the walls of the building. The width of the fire passage is taken equal to 3 m. Most sites in the mechanical assembly shop have the category of production "d," so the entire workshop as a whole also belongs to the category "d." In the production quarter, in addition to the mechanical assembly workshop, also designed: tool, repair and mechanical and stamping workshops with fire hazard categories "d." Distances between buildings in the building area in accordance with the conditions for providing solar insulation in the building premises are taken equal to 23.2 and 22.2 m, which is more than the minimum fire gap for buildings of this fire hazard category - 12 m.

The designed workshop provides for eight entrances and two entrances to the household room. Fire ladders of the following types shall be installed along the perimeter of the mechanical assembly shop:

Vertical steel with a width of 0.7 m with platforms at exit to the roof - one along the entire height of the building and four at height differences;

Three marching steel 0.7 m wide with platforms in 3 m with handrails, which will be located near the abc and will have access to it.

In a steel frame, metal structures are not protected from fire.

In the event of a fire, evacuation will be carried out through two swing gates with dimensions - 4.2m × 4.2m, as well as exits through the administrative building located during the evacuation of people (they have a height in the light of more than two meters).

Engineering equipment

The water supply system is provided by a dead end centralized. The production building will be equipped with water supply separately domestic, separately industrial and fire-fighting.

The sewage system shall be integrated for the disposal of domestic and industrial wastewater, provided they are treated together. After treatment, waste water will be supplied to the citywide collector.

The heating system of industrial buildings is accepted depending on the device and modes of the adopted ventilation and air conditioning systems. In this course design, an air heating system is designed. In this workshop, air heating will be combined with plenum air ventilation. To prevent large masses of cold air from entering the workshop when opening the gate in winter, a thermal curtain device is designed at the entrances from the street (near the gate).

Ventilation is designed in this course design of forced plenum and exhaust with mechanical motive. Aeration will be provided through a system of controlled plenum and exhaust holes. Aeration is mainly used in workshops with significant heat losses. In our case, production does not release a large amount of heat, so aeration is carried out through framugs, windows, doors and gates. The opening area is more than 1% of the floor area of the premises. The area of the plenum openings is equal to the area of the exhaust openings. This is done so that there is no violation of aeration or "thrust rollover." With plenum ventilation, fresh air will be supplied to the workshop, and air contaminated with hazards will be removed from the workshop. The main structural elements of this ventilation: air intake device; plenum chamber with fan and electric motor; air ducts for air transportation; plenum nozzles for air distribution in rooms; control devices; exhaust shafts equipped with deflectors. Air ducts intended for distribution of cleaned and heated air in the shop areas are designed in round section from sheet steel and suspended from structures of frames (trusses).

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.

Superstructure light-aeration lamp in metal frame is used as exhaust and plenum device. Rack-type mechanism for opening longitudinal bindings will operate in automatic mode from sensors installed in aeration openings.

Lightning protection systems are provided in the designed building. Lightning protection of the industrial building will be provided by lightning detectors on the roof of the building with the installation of a lightning protection net in the waterproofing of the roof.

All equipment in the workshop will operate at 380V voltage. The electrical cable will pass through the bushing, and be distributed to the equipment that consumes electricity. Grounding of all current-carrying parts of the equipment is provided. Power supply of the designed mechanical assembly shop is provided by the device of the complex transformer substation KTP 10kV/0.38kV.

Swing gates are equipped with a mechanical drive, a set of devices 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.

To prevent accidents during crane operation at the ends of the building, crane tracks are equipped with a device that automatically turns on braking, and are limited by end stops. End stops are welded to crane beam so that impact force is transmitted through end support rib to building frame. To mitigate the impact, they are equipped with spring shock absorbers.

Fire and security alarms are provided in the designed building of the mechanical assembly shop.

The workshop also provides a telephone communication device, which will be a branch from the city telephone network and will operate at a low tone.
