Description

The invention relates to the construction and can be used in the installation of coatings for industrial buildings in enlarged blocks. There is a known method of installation of coatings of one-story industrial buildings in enlarged blocks consisting of roof frames, subrafter structures, vertical and horizontal stiffenings, assembled on the conveyor line below and supplied to the design position by a special installer along the paths previously made in the span 1 to be mounted. allows to reduce the construction time and labor-intensive work, but it also has a number of drawbacks: the additional consumption of metal in connection with rigidity and paired supports opilnye structure mountable device in each span special installer and for its movement paths, the complexity of connections between the blocks. In addition, this requires a free site for the construction of a conveyor line, which is not always feasible when reconstructing existing workshops. The closest to the invention to the technical essence and the achieved result is a method of mounting the coating in enlarged blocks, containing forming a block of the cover from trusses by connecting them with stiffness bonds, lifting the blocks to subrafter structures and moving them to the design position 2. The disadvantage of this method of installation is The fact that to ensure the rigidity of the block during lifting and transportation, mounting vertical and horizontal connections are necessary, which leads to excessive metal consumption of the coating. The aim of the invention is to reduce the metal consumption of the coating by partially eliminating the stiffness bonds. The goal is achieved in that according to the method of installation of the coating by enlarged blocks containing the formation of blocks of the covering from trusses by connecting them with stiffness connections, lifting the blocks to subrafter structures and moving them to the design position, forming the blocks of the covering from farms is carried out on subrafter structures of magnitude. equal to the value of the temperature compartment of the building in its longitudinal direction. FIG. 1 shows a plan for assembling a coating unit in plan; in fig. 2 shows section A-A in FIG. 1. The method consists in assembling a block consisting of truss structures 1 with removable carts 2 fixed to their support units, horizontal 3 and vertical 4 connections of rigidity, runs 5, struts 6, carried out at the end of the span on subrafter structures 7, pre-mounted on columns 8. In this case, horizontal 3 and vertical 4 stiffness bonds are installed only between the first two truss structures of the block. The size of the assembled unit is equal to the size of the temperature compartment of the building in its longitudinal direction. Moving the assembled unit along the span along the subrafter structures is performed by a winch 9. The lengthy blocks are assembled sequentially and, as they are assembled by the winch 9, are moved from the operating zone of the erecting crane 10, after which subsequent structures are added to the already assembled designs of the unit. For the safety of assembling the blocks, assembly platforms 11 are arranged at the end of the span. The use of this method of assembly allows the metal construction of the coating structures to be reduced by about 5-6%, since assembly connections of each truss structure are not required. In the case of building blocks of length equal to the length of the temperature compartment of the building, wiring connections are not required at all, since the rigidity of the block is provided by the connections necessary to ensure the geometric stability of the coating structures in the design position. This method allows you to mount a coating of blocks of much larger dimensions as compared to previously used ones, which significantly reduces the number of joints between the blocks, and hence the laboriousness of construction and installation works. The proposed method of installation of the coating is especially efficient to use in the conditions of the reconstruction of existing workshops when there are no free areas for the placement of a conveyor line.
