Problems solved by technology
", the cast-in-place concrete is poured into the hole to form a cast-in-place concrete rod. This kind of tire mold component solves the problem of force transmission in the middle of large-scale components. However, the holes in this tire mold component are easily damaged during the application process. The pressure generated when pouring concrete is easy to swell the hole wall, so that the concrete enters the tire mold, which reduces the hollow ratio of the cast-in-place concrete hollow slab and affects the structural force transmission; moreover, this relatively large tire mold It is not easy to lift and install, and it is easy to be damaged during the lifting process. Therefore, it is urgently needed to develop a new type of lightweight permanent carcass for concrete filling.

Embodiment Construction
[0132] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0133] As shown in the drawings, the present invention includes a lightweight carcass 1, which is characterized in that there is at least one hole 6 with openings at both ends for pouring in-situ concrete in the lightweight carcass 1, which runs through at least one of the lightweight carcass 1. On the two surfaces, at least one stiffening member 40 is arranged in the hole opened at both ends, and at least one end of the stiffening member 40 is connected to the wall of the hole. As shown in Figure 91, the lightweight carcass 1 has holes 6 with openings at both ends for casting in-situ concrete in the lightweight carcass 1, which run through at least the lightweight carcass 1 On the two surfaces, a stiffening member 40 is arranged in the hole opened at both ends, and the stiffening member 40 is connected to the wall of the hole.

The present invention relates to a light permanent form for filling concrete. It includes a light form body, and is characterized by that in the light form body interior at least one hole whose two ends are opened for in-situ depositing concrete is passed through at least two surfaces of said light form body, and at least one stiffening component is set in the hole interior, at least one end of said stiffening component is connected with said hole wall. Said light permanent form can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow floor, roof, wall body, foundation bedplate and oper-web bridge, etc.
Description
(1) Technical field [0001] The invention relates to a lightweight permanent carcass for concrete filling. (2) Background technology [0002] Beamless floor is currently the most widely used floor structure for cast-in-place concrete floors. It has the advantages of fast construction speed, small structural height, flexible division of indoor areas and no need for ceiling decoration. The lightweight permanent tire mold filled in it There are various hollow tubes and boxes, and the boxes are hollow or solid. For example, Liang Jun of Shijiazhuang City, Hebei Province, applied for the formwork used in the utility model patent with the patent No. ZL00203695.9 on February 23, 2000 and the name "combined concrete hidden rib floor cover plate", on the second page of the instruction manual Lines 5 to 7 describe that "the formwork can be solid or hollow, and can be made of light materials such as plant straw, glass fiber reinforced plastic, thin iron plate, glass fiber cement, etc.,...
