Light weight tire shuttering member for cast-in-situ concrete

Abstract

The invention provides a light molding bed component for cast-in-situ concrete, comprising a polyhedral solid lightweight material component (1). The invention is characterized in that the polyhedral solid lightweight material component (1) is an integral solid piece; a reinforcing rib (2) is arranged on the surface of or inside the polyhedral solid lightweight material component (1); at least two polyhedral solid lightweight material components (1) are vertically arranged on the same strip bottom board (19) to form unitized assemblies with inner rib mold forms (18) among one another. Therefore, when the molding bed component is applied to a cast-in-situ concrete floor, the cast-in-situ concrete enters the inner rib mold forms to form cast-in-situ concrete inner ribs so as to improve the mechanical property of the floor; meanwhile, the molding bed components are connected into a whole through connecting pieces to form unitized molding bed components, thereby greatly improving the construction efficiency and the construction speed of the floor. The light molding bed component for the cast-in-situ concrete is applicable to floors, roofs, walls, foundation slabs and bridges of cast-in-situ reinforced concrete or prestressed reinforced concrete, in particular to hollow flat slabs.

Description

[0001] This application is a divisional application for an invention patent application with an application date of September 15, 2003, an application number of 200610077952.9, and a title of "a lightweight tire mold component for cast-in-place 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, and the light permanent tire mold filled in it has various hollow tubes and boxes, and the boxes are hollow or solid. For example, Liang Jun, Shijiazhuang City, Hebei Province, applied for a patent number ZL00203695.9 on February 23, 2000, a utility model patent named "Combined Concrete Concealed Ribbed Floor Slab". The description discloses a formwork member, which It can be solid or hollow, and its shape can be made into rectangular, circular, polygonal and other shapes according to design requirements...

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, this lightweight tire mold member has no reinforced structure, so the overall strength and rigidity of the lightweight tire mold member are poor, and it is prone to cracking of the lightweight tire mold member
