Supporting method of factory building roof system at super large column-removed spacing

Abstract

The invention discloses a method for supporting a factory-building roofing system at a huge pumping column space, which relates to the technical field of construction structure design. According to normal column space (6), an on-beam steel column (2) is added in corresponding position on the top surface of a large box-shaped crane beam (1) at the huge pumping column space (7); the top of the on-beam steel column (2) is articulated with a steel roof truss (3), and the foot of the on-beam steel column (2) is articulated with the large box-shaped crane beam (1). The method effectively solves the problem of how to support a factory-building roofing system at a huge pumping column space and causes the arrangement of the roofs to be more unified and the whole rigidity of the factory buildings to be evener, thereby achieving good technical effect and economic benefits. The method is mainly used for the design of the supporting of a factory-building roofing system at a huge pumping column space.

Description

technical field [0001] The invention relates to the technical field of building structure design, in particular to a method for supporting the roof system of a factory building at a super large spacing between drawn columns of a single-story industrial steel structure factory building. Background technique [0002] Generally speaking, the basic column spacing of single-story industrial steel structure workshops is mostly between 6 and 15m. Larger or even super-large column spacing is required in steel structure workshops, and some even reach more than 40m. In this case, more and more factory building columns have to be removed from the part of the factory building, and how to support the roof system has gradually become a difficult problem in the structural design of the factory building. [0003] The usual way to deal with this kind of problem in the past is: set brackets, commonly known as beams, at the pumping columns to support the steel roof truss or roof beams at the ...

AI Technical Summary

Problems solved by technology

This method is more suitable for dealing with the column spacing below 24m, but for the ultra-large column spacing of more than 30m, if this method is still used, the cross-sectional height of the bracket will be very large, and the steel consumption will increase a lot. The high cross-section of the joist will inevitably lead to an increase in the overall height of the factory building, further increasing investment, and the overall benefit is not good

At the same time, the out-of-plane rigidity of the upper columns of the factory building columns on both sides of the pumping columns is very small, which may be difficult to bear the load transmitted by the brackets, causing more structural problems
