Problems solved by technology

Although this kind of truss has achieved good results in environmental protection, total investment, space utilization and later maintenance, due to the large lateral width, high height, heavy weight, complex structure, transportation conditions and installation conditions of this kind of truss For high reasons, the single-belt overhead truss has been used. When the number of belt conveyors in the same direction is large and the span is large, it not only occupies a lot of land, but also consumes a lot of steel. It is easy to deform during the installation process, and it is inconvenient to maintain after it is put into production.

Abstract

The invention relates to a modular construction method of a large-span, super-wide and super-heavy truss. The construction method comprises the following steps that structural modeling analysis is conducted on the truss through modeling software, and factory modules of the truss and the positions and structural forms of temporary reinforcing structures of the factory modules are determined; the truss is assembled and manufactured, and the temporary reinforcing structures are mounted; the truss is divided into the multiple modules according to models, according to the transport requirement, for a single piece during dividing, the largest width is smaller than or equal to 8.5 m, the length is smaller than or equal to 26 m, the weight is smaller than or equal to 60 t, and then the modules are transported to a construction site in batches; construction preparation is conducted before truss mounting; the modules are assembled into the whole truss; the temporary reinforcing structures are dismantled; and the truss is overall hoisted in place. The modular construction method has the characteristics that construction is convenient and rapid, safety and reliability are achieved, the cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of truss construction, and in particular relates to a modular construction method for a large-span, ultra-wide and overweight truss. Background technique [0002] In recent years, some metallurgical plants, mines, power plants, raw material ports, etc. in China are required to optimize the routing of the original belt conveyor system in the factory due to environmental protection requirements and increase in production capacity to increase the original transportation capacity. Therefore, it is necessary to carry out a large-scale transformation of the original belt conveyor truss, and use multiple belt conveyors in parallel in a closed steel frame to reduce the occupied area and the total investment. Although this truss has achieved good results in environmental protection, total investment, space utilization and later maintenance, but due to the large lateral width, high height, heavy weight, complex struct...
