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
[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0068] As shown in the accompanying drawings, the present invention comprises a lightweight carcass 1, the lightweight carcass 1 includes an upper shell 5, surrounding side shells 6, and a lower shell 7, and the upper shell 5, surrounding side shells 6, and lower shells 7 form a closed space. The cavity is characterized in that it also includes a through-hole pipe 8, which is arranged in the closed cavity of the lightweight carcass 1, and there is at least one existing hole formed by the through-hole pipe 8 in the light-weight carcass 1. The hole 2 for pouring concrete runs through the upper and lower shell surfaces of the lightweight carcass 1, the hole 2 is the through hole of the hollow through-hole pipe 8, and the hollow through-hole pipe 8 is integrally formed with the lower shell 7 or the upper shell 5. As shown in Figure 10, the lightweight perma...

A light-permanent tube shell for filling concrete is composed of light tube(1), through-hole pipe(8) and hole(2) for pouring cast-in-situ concrete. Said light tube(1) is composed of top shell(5), peripheral side shells(6) and bottom shell(7), said top shell(5), peripheral side shells(6) and bottom shell(7) are enclosed into a closed cavity, through-hole pipe(8) is set inside closed cavity of said light tube(1), at least one hole(2) for pouring cast-in-situ concrete is penetrated top and bottom shells surfaces of said light tube(1),said hollow through-hole pipe(8) is integrated with top shell(5) or bottom shell(7). It can be used for various hollow and beamless building roofs of cast-in-situ reinforced concrete or pre-stressed reinforced concrete, basic baseboard, wall and bridges.
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...
