Turnable lightweight steel structure and precast concrete slab structure system and construction method thereof

Abstract

A turnable lightweight steel structure and concrete prefabricated slab structure system and its construction method, including a lightweight frame and a lightweight panel. The lightweight frame includes a set of adjustable column foot structures, a set of columns, a set of main beams, a set of A set of secondary beams and a set of inter-column supports. The columns, main beams and secondary beams are all high-frequency welded thin-walled H-shaped steel. There is a flexible backing plate between the bottom of the adjustable column foot structure and the ground of the pool. Aggregate concrete prefabricated slabs, the present invention is a light-weight structural system that is easy to transport, efficient in installation and dismantling, safe in structure, good in economy, and can be used in turnover; it only needs manual cooperation with small machinery to complete the transportation and installation work, and the steel components Full bolt connection, no welding work in on-site construction, improving the efficiency of structure conversion construction, reducing costs, and achieving quality control, safety and reliability, multiple structural conversions can be achieved to meet the site function conversion requirements, and can effectively realize the rapid disassembly and assembly of the converted structure, Safety and stability, cost saving, and improvement of work efficiency.

Description

technical field [0001] The invention relates to a prefabricated structure system, in particular to a turnable lightweight steel structure and concrete prefabricated slab structure system and a construction method thereof. Background technique [0002] In recent years, the concepts of industrialization, green construction, and existing building renovation have become more and more widely used in the field of building construction. Due to changes in use requirements, blindly destroying the main body of the structure for new construction is too costly and does not conform to the concept of green and sustainable. In order to realize the change and transformation of the site use elevation, and realize the multiple turnover and conversion of the structural system, there are various solutions. Comprehensive consideration should be given to the combination of structural system and platform panels. [0003] Structural system: It can adopt the form of ordinary steel structure support...

Problems solved by technology

[0006] The purpose of the present invention is to provide a turnable lightweight steel structure and concrete prefabricated slab structure system and its construction method. It is necessary to solve the problems of large amount of steel used for steel structure support, low installation and dismantling efficiency, and easy damage in existing building renovation platforms. There is a structure; the scaffolding frame structure has large deformation, poor top surface flatness, small vertical component spacing, uneconomical use for a long time, and it is difficult to meet the technical problems of the modified use requirements; it is also necessary to solve the aluminum alloy panels. The rigidity is small, The ability to resist deformation is slightly poor, the cost is high, and the economic performance is poor; the durability of the wooden box panel is poor; the ordinary concrete prefabricated panel is heavy, the installation and disassembly efficiency is low, and it does not meet the technical problems of multiple turnover needs
