A hollow component for concrete

Abstract

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 the rib cavity (2) center also the opposite pulls with the gap brace (3) is the whole gap prefabrication module (4), Gap prefabrication module (4) and empty stomach form (1) other wall companies are the wholes. Thus, when the empty stomach component applies to cast-in-place the hollow ceiling, does not affect the hollow ceiling the construction quality, simultaneously constructs the efficiency also greatly to enhance, moreover, because in the rib cavity the opposite and the gap brace pull for the whole gap prefabrication module, thus the empty stomach component manufacture is easier, the intensity is higher, is suitable for each kind cast-in-place 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 ...

AI Technical Summary

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
