Problems solved by technology

This formwork member has the characteristics of simple structure and convenient construction and transportation. After being applied to the floor, there is no force-bearing and force-transmitting member of the floor in the formwork member, especially when the formwork member is larger in size, the performance is better. Obviously, at the same time, the strength of the formwork components is not high, the production is inconvenient, the production efficiency is low, and the cost is high. Therefore, it is urgently needed to develop a new type of lightweight permanent casing for concrete filling.

Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0074] As shown in the drawings, the present invention includes a lightweight carcass 1, which includes an upper shell 5, surrounding side shells 6, and a lower shell 7, and is characterized in that there is at least one cast-in-place concrete pouring in the lightweight carcass 1 Holes 2 are used to penetrate the upper and lower shell surfaces of the lightweight carcass 1. The holes 2 are open at both ends of the surface. There is a closed wall between the openings of the two ends of the hole 2. The closed wall is separated from the inner cavity of the lightweight hollow member. , at least one outer wall is formed by cementing two embryo body edges in a wet embryo state, under the cemented embryo edges there is a support member 4 superimposed on the embryo edges. As shown in Figure 2, its lightweight permanent carcass includes a lightweight carcass 1, i...

Abstract

The present invention relates to a light permanent form for filling concrete. It includes a light form body; said light form body includes upper plate, peripheral side plate and lower plate. It is characterized by that in the light form body at least one hole is set, said hole is passed through upper and lower surfaces of said light form body, and can be used for in-situ pouring concrete. Said light permanent form is applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation baseplate and open-web bridge, specially, it is applicable to hollow beamless floor.

Description

(1) Technical field [0001] The invention relates to a lightweight permanent carcass for concrete filling. (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, the upper plate, the surrounding side walls, and the lower bottom form a polyhedral cavity, and the upper plate, the surrounding side walls, and the lower bottom contain fiber reinforcements. This formwork member has the characteristics of simple structure and convenient construction and transportation. After being a...
