Modularized rapid-installation-type unloading and external protecting integrated system for fabricated building

Abstract

The invention belongs to the technical field of building construction, and in particular relates to a modular quick-loading unloading and external protection integrated system for prefabricated buildings. The system includes a steel platform; the outer walls of the structural floors of each floor are provided with reserved holes through the outer walls; Screw rods are threaded with compression nuts; hanging lugs are arranged on both sides of the cantilever section, and a traction rope connecting the two is set between the lifting lugs and the closed-loop end of the pulling screw; the system also includes a support frame, A mounting hole is arranged on the support frame, and the pull screw rod penetrates into the mounting hole and the support frame is compressed and fixed at the reserved hole by the compression nut; the top of the support frame is fixed with a mesh screen plate-like external rack. The system has a high degree of modularization, good safety in use, simple and quick operation, and low production cost. The whole system can rise and fall simultaneously with the building structure operation, which can significantly improve the actual construction progress.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a modular quick-loading unloading and external protection integrated system for prefabricated buildings. Background technique [0002] In recent years, with the development of the economy, the construction industry has paid more and more attention to energy consumption and environmental pollution; prefabricated buildings have the characteristics of environmental protection, reducing on-site construction pollution, and high construction efficiency, and can complete the construction of houses in a short period of time. It is one of the preferred ways of modern house construction. During the construction process, the unloading platform and the outer protective parts are essential. The unloading platform is used for the transfer of materials between layers, and to realize the transportation operation requirements of blocks and mortar in the secondary struct...

AI Technical Summary

Problems solved by technology

The defect of the above-mentioned existing unloading platform structure is that: at present, for the design of the anchor point at the upper floor, the pre-casting method is adopted, that is, the steel bar is bent into an "Ω" shape at the design point and the two legs of the steel bar are bent. embedded in the exterior wall

However, on the one hand, in order to achieve the connection between the anchor point and the lower steel platform, the anchor point usually needs to be arranged at the window opening of the outer wall or the top beam of the door opening, which makes the operation of removing steel bars dangerous.

On the other hand, it is impossible to make the cross-section of the steel bar completely flush with the exterior wall by manual cutting, which leads to the need to increase the grinding process, which brings great troubles to the on-site operators
