Lightweight tyre mould component for cast-in-situs concrete

Abstract

Disclosed is a lightweight tire shuttering member for cast-in-situ concrete, comprising a polyhedral solid lightweight material member (1), wherein at least two polyhedral solid lightweight material members (1) are arranged at intervals, thus forming an inner rib molding chamber (2), the inner rib moulding chamber (2) is provided with at least one spacing tension member (3) for connecting the opposite or adjacent polyhedral solid lightweight material members (1). The invention can be applied to various cast-in-situ reinforced concrete or prestressed reinforcement concrete's storied-building roofings, house roofings, foundation slabs, walls, and bridges.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 15, 2003, an application number of 03157893.4, and a title of "A Lightweight Tire Mold Member for Cast-in-situ Concrete". (1) Technical field [0002] The invention relates to a lightweight tire mold component for cast-in-place concrete. (2) Background technology [0003] 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 req...

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, when this lightweight tire formwork member is constructed, it needs to be constructed individually, and it is inconvenient to locate each other, and it is prone to misalignment, which affects the construction quality of the floor and also affects the construction efficiency. Therefore, , it is urgently needed to develop a new type of lightweight tire mold member for cast-in-place concrete
