Description

The invention relates to the construction and can be used for coating industrial buildings.

A large-block coating is known with symmetrical blocks with double-console girders, with two truss trusses supported by subrafter trusses, connections, and a profiled steel sheet fl.

The disadvantage of this coating is the increased metal intensity of the coating due to the strength of paired subrafter trusses. In addition, since the roof trusses do not rest on the columns,. In order to create a workable coating system and building framework as a whole, it is necessary to set up additional links in the interconnect space, which also increases the intensity and complexity of the work.

Closest to the invention is the building coverage of the blocks, including cantilever girders, a subrafter design supported on columns and two roof trusses arranged in increments greater than half the pitch of column 2.

The disadvantage of this solution is that the trusses do not rest on the columns and do not create the transverse support frames of the framework, which entails the establishment of additional connections ensuring the spatial operation of the framework. In addition, the increased metal content of the adjustment beams due to the significant support reactions of the trusses transmitted from the block of adjacent spans.

The purpose of the invention is to reduce the material consumption of the coating.

The goal is achieved by the fact that in building a building of blocks, including cantilever girders, subrafters, a structure supported on columns and two roof trusses are arranged in increments of more than half a step of columns, one of the roof trusses is supported on the columns of the building, and the other on a subrafter design, with each of the blocks of adjacent spans located with the supporting truss trusses on the subrafter construction in different lengths. the last points symmetrically separated from the columns of the building.

FIG. 1 depicts a coating at the level of the bottom of the Soviet trusses, a fragment of the plan; in fig. 2 - section AA on the fit. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 - blocks of type 1, a fragment of the plan.

Asymmetrical coating units with single cantilever girders 1 include two trusses 2, one of which rests on columns 3 and the other on a subrafter (farm) 4. The blocks of adjacent spans are mutually displaced along a row of columns in such a way that their trusses are supported on subrafter beams (trusses) at two points of different length along the beam symmetrically separated from the columns of the building. Such mutual displacement of the truss of the neighboring spans reduces the bending moments on the subrafter beams (trusses) 4 and, accordingly, reduces their metal intensity,
