2. General part (characteristic of the mounted building)

Industrial building (warehouse of materials and specialized equipment) - designed as one-story, single-span, rectangular in plan. The building is framed. The pitch of the columns is 6 m, the span is 24 m. The length of the building is 234 m. The construction district is Taishet, Irkutsk region. The start of construction is November 15th. Wall panels - three-layer, type "sandwich," brand PMSM, thickness 200 mm.

The columns of the main frame of the building are reinforced concrete, with a section of 800x400 in the base, grade 3K132 for a bridge crane, with a lifting capacity of 5 tons. The columns are reinforced with welded frames and formed of concrete of grade 200. The foundation for the main columns is monolithic reinforced concrete (series 1.412). It consists of a cup-type sub-column, measuring 1500x1200x1800 mm, two stages - 2700x2400x300 mm and 2100x1800x300 mm. The foundation mark is FV 1318. Foundations are reinforced with typical rebar grids and flat frames. The foundation of the fachwerk post is monolithic reinforced concrete. It consists of a cup-type sub-column with a size of 600x900x1200 mm, one stage - 1200x1500x300mm. Foundation beams of grade 1BF60, trapezoidal section, size 200x160x300 mm, length - 5950 mm.

Rafter truss - metal (brand F1), 24,000 m long, 3680 mm high. Crane beam - metal, 5970 mm long. Mark BK32.

Linkage elements, fuselage posts, horizontal fuselage elements, beams and canopy posts, vertical coating connections, coating runs are made of metal profiles (see specification of prefabricated elements).

12. Development of methods to terminate joints

Work on grouting of joints, sealing of joints is started only after checking the correct installation of structures, acceptance of welded joints. Before soaking, the joint cavities must be cleaned of dirt and moistened with water. Sealing with flexible gaskets and mastic is arranged, which prevents moisture from falling into conjugate units. Concrete or mortar mixture is used to terminate joints, the concrete grade should not be lower than the design grade of concrete of the structures to be connected .

Joints that do not perceive design forces are sealed with grade solution not lower than 50. The laid mixture is compacted. After laying, the necessary conditions must be created to ensure hardening. Spatial rigidity and stability of the structure depends on the quality of seating of the joint.

Termination of joints consists of several processes:

- welding and protection of embedded parts against corrosion;

-molding of joints with mortar or concrete;

-germetization for wall panels;

- welding of reinforcement outlets and embedded parts.

Before welding, the outlets should be cleaned, then covered with anticorrosive paint, which is applied under pressure by gas-flame spraying.

13. Construction plan for the construction period

13.1. General Information

The construction site plan is called the site master plan, which shows the arrangement of the main installation and lifting mechanisms, temporary buildings, structures and installations built and used during the construction period.

There is a site-wide and object-wide construction plan (SGP). Site-wide SGP is being developed for the construction of the complex or for individual continuous buildings and structures. Object SGP is designed separately for all buildings and structures under construction, which are part of the site-wide SGP. It is compiled in the construction organization for one or more buildings and structures at the stage of detailed documentation as part of the PPR. The differences in the design methods between the GWP as part of the PIC and the PPM are reduced, in essence, to the degree of detail of the development of the plan and the accuracy of the calculations.

The SGP is part of the integrated construction documentation, and its solution should be linked to the rest of the project, including the construction deadlines set by the schedule; SGP solutions shall meet the requirements of construction standards; temporary buildings and structures, as well as installations, are located in areas not intended for construction of SGPs should ensure rational passage of cargo flows at the site by reducing the number of transshipments and reducing the transportation distance. SGP should ensure the greatest satisfaction of household needs of construction workers; decisions taken in the SGP shall meet the requirements of safety, fire safety and environmental conditions; temporary construction costs should be minimal.

Design of temporary roads

For construction needs, permanent and temporary roads are used, which are located depending on the accepted traffic pattern. The traffic diagram at the construction site is developed based on the accepted technology of the order of construction and installation work, the location of storage areas and the type of materials. We trace intra-border roads according to a circular scheme with two entrances-exits.

Structures of temporary roads are adopted depending on traffic intensity, type of machines, bearing capacity of soils. We accept natural dirt roads.

The main parameters of temporary roads with the number of lanes-1:

- lane width - 3.5 m, with expansion in places of turns and unloading up to 6 m;

- roadway width - 3.5 m;

-Roadway width - 6 m;

-the smallest radii of the rounding in the plan are 12 m.

When routing roads, minimum distances shall be observed in accordance with TB:

- between road and storage area: 0.51 m;

- between the road and the crane tracks 6.5.. 12.5 m;

- between the road and the fence of the site: 1.5 m.

At the entrance, it is mandatory to install signs with a traffic scheme and speed limit.

13.2. Calculation of crane installation and safe areas

Define Crane Coverage Areas

The installation crane shall be placed on the basis of the possibility of installation of structures by this crane and the safety of these works

a) Crane operating area (crane service area):

Roxl = Rmax = 11.4 m,

where Rmax is the arrowhead .

b) Cargo movement area:

Rpg = Rmax + 0.5Lmax = 11.4 + 0.5 24 = 23.4 (m),

where Lmax is the length of the longest element (24.0 m);

c) Hazardous area:

Rpg = 0, 5Bgr + Lgr + x = 0.5 × 0.26 + 24 + 5 = 29.13 (m),

where Vgr = 0.26 m is the width of the truss; Lgr = 24 m - truss length; x = 5 m - minimum distance of cargo departure at its fall (Table 3 [22]). The heaviest structure that can be mounted at the maximum departure of the rafter truss

Areas of constantly operating hazardous production factors associated with the operation of installation and lifting machines include places over which cargo is transported by lifting cranes.

Areas of permanently operating hazardous factors include areas of the building under construction and floors of buildings and structures in one grip, above which structures or equipment are installed (dismantled).

Installation area - a space where it is possible to drop the load when installing and fixing elements. It is equal from the edge of the building plus 7 meters.

The working zone of the crane is called the space located within the line described by the crane hook;

The cargo transfer zone is referred to as the space within the range of possible movement of the cargo suspended from the crane hook.

A dangerous area of ​ ​ crane operation is a space where it is possible to drop the cargo when moving it, taking into account the likely dispersion when falling.

14. Special conditions

Wall Panel Storage

Packed bags with Thermoland panels should be stored at the construction site on a pre-prepared flat surface. Packages are placed on wide and strong supports, ensuring uniform distribution of the weight of the package on the lower panel and protecting it from deflection or damage.

Packages with panels are not allowed to be pushed or dragged, since in this case the sliding of the panels in the bag can damage their surface.

It is forbidden to lay heavy objects on the panel package or on unprotected panels to avoid damage to the panel surface.

Thermoland packs cannot be stacked on top of each other. The distance between packages shall be at least 100 mm.

It is recommended not to disturb the factory packaging of the package, which ensures the watertightness of the package. If the package is broken, it is necessary to protect the bag with the remaining panels from moisture with polyethylene film.

When storing packaged packages with panels in the open air (not under the canopy), protect the upper panel from direct sunlight. Otherwise, removing the protective mounting film will be difficult. Shelf life of panels with unsalted protective mounting film is not more than three months.
