Cast-in-place concrete shuttering member

Abstract

A die shell brace member for casting-in-place concrete includes a polyhedron solid lightmaterial brace member characterizing that at least one of its sides extends along its bottom to form a cantilever slab. Thus, after the member is used in casting-in-place concrete floors, the cantilever can play the rote of a form of cast-in-place concrete ribs between shell members since the side of the member extends along its bottom to form a cantilever, and construction forms can be omitted.

Description

(1) Technical field [0001] The invention relates to a formwork 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. 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 that the application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is an application for a patent for invention of "a cavity structure formwork for c...

Problems solved by technology

However, after this polyhedral solid lightweight material member is applied to the cast-in-place concrete floor, it still needs to support the construction formwork, which reduces the construction speed and increases the construction cost. for urgent need
