Light stuffing mould component for concrete poured-in-situs

Abstract

A light mold component that is cast-in-place concrete. It includes polyhedron solid light material component that at least one vertical corner is vertical reentrant corner. It can effectively avoid the phenomenon of stress concentration while constructing and the cracks. The light mold component is simple structure, high intension, anti-distortion, anti-vibration, low cost and easy to be constructed.

Description

(1) Technical field [0001] The invention relates to a lightweight tire mold component for cast-in-place concrete. (2) Background technology [0002] At present, the cast-in-place concrete floor is a widely used floor structure. The lightweight permanent tire mold filled in it has various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, is called the utility model patent of "combined concrete concealed rib floor cover", and a formwork member is disclosed in its specification sheet. It can be solid or hollow, and its shape can be made into rectangle, circle, polygon and other shapes according to design requirements. Another example is the patent No. ZL01206422.X invented and applied by Guiyang Ma Kejian et al., and the name is the utility model patent of "built-in formwork for fasting sandwich panels". The built-in formwork is solid, and the formwor...

AI Technical Summary

Problems solved by technology

The above-mentioned solid cast-in-place concrete light-weight tire mold members are applied to cast-in-place concrete floors, and are both formwork members and prefabricated filling members, with simple structure, high strength, excellent deformation resistance and vibration resistance. , easy to manufacture, low cost, etc., however, at the intersection of the cast-in-place concrete ribs between the cast-in-place concrete upper plate or lower plate and the lightweight tire formwork components, the force of the floor is relatively high. Complex, concentrated stress, easy to produce cracks, even cracking damage, therefore, the development of a new type of lightweight tire mold components for cast-in-place concrete has been urgently needed
