Problems solved by technology
However, when this kind of thin-walled box is used as a hollow formwork, it needs to be constructed individually, and it is inconvenient to locate each other, and it is prone to misalignment, which affects the construction quality and efficiency of the hollow slab. At the same time, at the corner of the hollow formwork, the floor The stress of the cover is more complicated, the stress is more concentrated, and it is easy to produce cracks, or even crack and damage. Therefore, it is urgent to develop a new type of hollow member for concrete.

Embodiment Construction
[0068] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0069] As shown in the accompanying drawings, the present invention includes fasting formwork 1, which is characterized in that at least two fasting formworks 1 are arranged alternately, and the opposite surfaces of the fasting formwork 1 form a cast-in-place concrete inner rib cavity 2, and the inner rib cavity 2 has at least one spacer brace 3 that connects the hollow formworks 1 on the opposite or adjacent surfaces into one, and at least one corner of the hollow formwork 1 is provided with a female corner 4 . Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is an empty stomach formwork, 2 is an inner rib mold cavity, 3 is a brace, and 4 is a female corner. In the following drawings, those with the same number have the same description. As shown in Fig. 1, two hollow mold shells 1 are ...

Disclosed is a hollow component for concrete, which comprises a hollow shuttering (1), characterized in that at least two hollow shuttering (1) are alternately arranged, the opposite faces of the hollow shuttering (1) form a on-site casting concrete inner rib die cavity (2), at least one tension brace piece (3) is arranged in the inner rib die cavity (2) for alternately integrating opposite or adjacent faces of the hollow shuttering (1), and a reentrant corner is arranged in at least one corner of the hollow shuttering (1). The hollow component is convenient for positioning when being applied to on-site casting concrete hollow floor, as a result, displacements are avoided and the construction quality and efficiency are guaranteed, and the reentrant corner can form on-site casting pier, pillar or reinforcing bar, so stress concentration of the floor and cracks are eliminated successfully. The invention is suitable for hollow floor, roof, soleplate, wall and empty bridge with on-site casting reinforced concrete or prestressed reinforced concrete, especially for hollow mushroom floor.
Description
(1) Technical field [0001] The invention relates to a hollow component for concrete. (2) Background technology [0002] At present, the cast-in-place reinforced concrete hollow slab is a widely used floor structure, which 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 molds filled with it are available in various hollow tubes and boxes, hollow or solid. For example, the patent No. ZL99232921.3, which the applicant applied for on March 10, 1999, is a utility model patent named "thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and two plugs. Used in hollow slabs as a lightweight permanent tire mold. Another example is the application number 99115666.8 filed by the applicant on November 29, 1999, and the name is "fiber-reinforced thin-walled box for filling cast-in-place reinforced concrete and...
