Cast-in-place concrete hollow cavity shuttering member

Abstract

A cavity die shell member using a casting-in plate concrete includes a top plate, side walls and bottom forming a polyhedron cavity die shell component, among which, the bottom extends from a side wall to form a cantilever slab characterizing in setting at least one reinforcing rod in the component, therefore, the component is stronger and more rigid, not easy to be broken and bears and transmits stres with the floor.

Description

(1) Technical field [0001] The invention relates to a cavity formwork component for cast-in-place concrete. (2) Background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, and the name is called "combined concrete hidden rib floor cover plate" utility model patent, wh...

AI Technical Summary

Problems solved by technology

However, there is no reinforcing structure in the cavity formwork member, so the overall strength and rigidity of the cavity formwork member are relatively poor, and the cavity formwork member is prone to damage. After being applied to the cast-in-place concrete hollow floor, it is also Unable to participate in the force bearing and transmission of the hollow floor
