Light moulding bed component for cast-in-situ concrete

Abstract

Disclosed is a lightweight tire shuttering member for cast-in-situ concrete, comprising a polyhedral solid lightweight material member (1), characterized in that the polyhedral solid lightweight material member (1) is an integral solid block body, the polyhedral solid lightweight material member (1) is a uniform solid block body, the polyhedral solid lightweight material member (1) is provided with at least a sheet of stiffening rib board (2), at least two polyhedral solid lightweight material members (1) are arranged on a bar-shaped bottom board (19) longitudinally to form a group assembly with an inner rib molding chamber (18). The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's storied-building roofings, house roofings, walls, foundation bedplates and bridges, especially for flat slabs.

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 03157895.0, 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., but there is no reinforcing structure in this lightweight tire mold member, so the overall strength and rigidity of the lightweight tire mold member are poor, and the phenomenon of damage to the lightweight tire mold member is prone to occur. After the cast-in-place concrete floor, it cannot participate in the force and transmission of the cast-in-place concrete floor
