Title:
CONSTRUCTION METHOD FOR BUILDING TRUSS AND FLOOR SLAB
Document Type and Number:
WIPO Patent Application WO/2017/121315
Kind Code:
A1
Abstract:
A construction method for building truss and floor slab, comprising the following steps: collecting building construction requirements, and designing a truss (1) structure; using finite element software to establish a structural model of the truss (1), and a lower building and an upper building connected by the truss (1); performing mechanical verification on the model, calculating and obtaining segments of the truss (1) that are under high force such that local reinforcement can be carried out by pouring concrete; using the finite element software to perform deflection analysis on the model, calculating the downward displacement of the bottom chord (12) after the truss (1) is subjected to loading; a gap is provided, following the downward displacement, at a position where two ends of the bottom chord (12) are connected with the columns, said gap being a post-welding node (5); fabricating the truss (1), and providing a post-welding port at a position on the column (4) corresponding to the post-welding node (5); carrying out field construction of the truss (1) and floor slabs. The method is capable of solving a series of technical quality problems in the prior art, such as an upper concrete structure tends to crack due to excessive deflection, as a steel truss has a higher elasticity in comparison to a regular concrete structure; and when subjected to loading, the settlement and deformation of the truss causes relatively high adverse lateral pressure on columns.
