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
[0112] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0113] As shown in the accompanying drawings, the present invention includes a lightweight carcass 1, which is characterized in that there is at least one hole 6 for cast-in-place concrete pouring in the lightweight carcass 1, which runs through the upper and lower surfaces of the lightweight carcass 1, and there is at least one plate in the hole Shape tie piece 21. As shown in Fig. 42, there is a hole 6 for pouring in-situ concrete in the lightweight carcass 1, which runs through the upper and lower surfaces of the lightweight carcass 1, and there is a plate-shaped tie member 21 in the hole.
[0114] The present invention is also characterized in that the plate-shaped tie member 21 in the hole 6 is arranged vertically. As shown in FIG. 43 , the plate-shaped tie member 21 in the hole 6 is arranged vertically.
[0115] The present invention is also cha...

The invention relates to a permanent tyre die for filling concrete, comprising light-weight carcass (1), characterized in that at least a hole (6) for pouring of cast-in-place concrete is set in the light-weight carcass (1) to pass through up-down surfaces of light-weight carcass (1) and at least a plate draw-knot part (21) is set in the hole. It is suitable for hollow floor, roof, wall, base plate and fasting bridge of cast-in-place reinforced concrete or pre-stressed reinforced concrete, especially the hollow girder-less floor.
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.,...
