AI Technical Summary

Technical Problem

The splicing joints of some existing precast ribbed floor slab modular components lack effective adjustment and limiting mechanisms, making it difficult to accurately control the joint width and alignment accuracy. Precast components are affected by changes in ambient temperature, resulting in thermal expansion and contraction deformation, leading to local cracking, warping, or a decrease in overall stability, which limits their application in large-span, high-stability scenarios.

Method used

The design adopts a two-way dense rib frame and lightweight insulation modules, combined with a grid-shaped steel mesh and reinforcement components. Through sealing insulation strips and steel support components, modular and stable assembly is achieved, and the splicing joints can be controlled on the construction site to avoid the effects of thermal expansion and contraction.

Benefits of technology

It improves the stability and thermal insulation performance of ribbed floor slabs, avoids local deformation caused by thermal expansion and contraction, and ensures the stability and overall flatness of large-span structures.

Abstract

The application discloses an assembled light composite heat-preservation dense-rib floor and a preparation method thereof, and belongs to the technical field of dense-rib floor. The assembled light composite heat-preservation dense-rib floor comprises a two-way dense-rib framework and a light heat-preservation module embedded in the center of the two-way dense-rib framework. Low-position installation grooves and high-position installation grooves are formed in the two-way dense-rib framework. Low-position installation beams are installed through the low-position installation grooves. High-position installation beams are installed through the high-position installation grooves. A plurality of rectangular grooves are formed in the high-position installation beams at equal intervals along the length direction. The low-position installation beams are connected through the rectangular grooves and the high-position installation beams, forming a cross-shaped installation frame. A sealing heat-preservation assembly for assisting the modular installation of the dense-rib floor is arranged in the two-way dense-rib framework. The dense-rib floor is flexible and convenient to assemble and can adjust the splicing joint according to the situation of the construction site, thereby reducing the risk of deformation of the dense-rib floor caused by thermal expansion and cold contraction after assembly, and the assembled structure is relatively stable.
