SU720116A1 - Roof of building - Google Patents

Description

The invention relates to the field of construction, to coatings used for various industrial, agricultural and public buildings with a pitched, low-sloping and flat roof. It is known to cover the building, including reinforced concrete ribbed plates, supported by roof and subrafter trusses, in which, for ease of passing communications and fastening of overhead transport, the roof and subrafter trusses are conjugated in one level and made of steel metal consumption. The closest solution of the known ones is a building covering, which includes reinforced concrete ribbed plates, installed on reinforced concrete trusses and subrafter trusses with supporting nodes 2. at different levels, which excludes the possibility of unification of co-structural solutions, their interchangeability with steel trusses, lean steel and reinforced concrete trusses on the same columns, udshaet conditions pass communications and increases the range of products. The purpose of the invention is to reduce metal consumption and improve the technological capabilities of a building. This goal is achieved by the fact that in the building covering, which includes reinforced concrete ribbed plates installed on reinforced concrete trusses and trusses with support nodes, the trusses and trusses are matched in one level, and the truss has a supporting node located between and lower ones themselves and rests on the upper face of the supporting or intermediate nodes of the subrafter truss. FIG. 1 shows a general view of the building; in FIG. 2, a node supporting a truss truss on a subrafter; in fig. 3 - pipeline pass in the support zone of trusses and subrafter trusses, in buildings g equipped with electric bridge cranes.

The floor of the building has reinforced concrete ribbed plates 1, reinforced concrete trusses 2 with a broken outline of the lower half of Sa 3, with raised upwards supporting legs Velgmi 4, located between the lower half of the som 3 and the upper 5, reinforced concrete subrafter trusses of b with supporting nodes 7, with a ledge 8 the bottom face of the support nodes 7 above the bottom face 9 of the bottom along ca.

When installing truss trusses 2 on subrafter trusses without their edges 9 and 10 of the lower boards are located on the same level.

Reinforced concrete columns 11, placed at one mark (on top), are installed along the middle piles. Underfloor trusses are used to weld the embedded parts of the support assemblies to the pillars of the Hi i trusses. reinforced subrafter trusses b. Reinforced ribbed slabs 1 are installed on truss 2 and subrafter 6; trusses and joints are also welded to the inserts.

With such a constructive solution to cover the building, the upper and lower trustable and subrafter trusses are on the same level, which eliminates a drop in the roof and provides more favorable opportunities for the overhead transport

and koiveeoov from span to span, skipping pipe-breeding, reduction of the nomenclature of columns. With the unification of constructive solutions according to the proposal, there are great opportunities for increasing the efficiency of building production and saving steel.
