Problems solved by technology
However, when this kind of thin-walled box is used as a hollow formwork construction, 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 of the hollow floor and also affects the construction efficiency. Therefore, a new type of There is an urgent need for hollow members for concrete

Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0059] 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-situ concrete inner rib cavity 2, and the inner rib cavity 2, there is at least one spacer brace 3 that connects the hollow formwork 1 on the opposite or adjacent surfaces into one, and the cross-sectional shape of the inner rib cavity 2 is I-shaped. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is an empty stomach formwork, 2 is a cast-in-place inner rib cavity, and 3 is a spacer brace. In the following drawings, those with the same number have the same description. Such as figure 1 As shown, two fasting formwork shells 1 are ar...

One kind Tong with the empty stomach component, including the empty stomach form (1), its characteristic lies in at least two empty stomach form (1) alternates with the arrangement, the empty stomach form (1) between the opposite constitution cast-in-place Tong in rib cavity (2), in the rib cavity (2) center has the form (1) alternates with to or the neighboring surface empty stomach joins a body at least a gap brace to pull (3), in rib cavity (2) section shape for I-shaped. Thus, when the empty stomach component applies to cast-in-place Tong the hollow ceiling, localization extremely convenient, is not easy to have the dislocation phenomenon to affect the hollow ceiling the construction quality, simultaneously constructs the efficiency also greatly to enhance, moreover, because in in the rib cavity section shape for I-shaped, cast-in-place Tong in the rib cavity has formed I-shaped, present value has formed with the rib cavity in I-shaped cast-in-place Tong rib, thus the ceiling intensity and the rigidity are bigger, is suitable to each kind of cast-in-place steel bar Tong or the prestressed rinforcement Tong hollow ceiling, the room lid, the foundation ledger wall, the wall, the empty stomach bridge use, specially uses in the hollow beamless roof use.
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 floor 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. It is used as a lightweight permanent tire mold in hollow-core slabs. 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 ...
