A hollow component for concrete

Abstract

One kind Tong with the empty stomach component, including the empty stomach form (1), characterized in that 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) to be separated the brace to pull (3), form (1) in establishes in at least an empty stomach has stiffener (4). Thus, the empty stomach component applies to when cast-in-place Tong hollow hugs covers, 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 the empty stomach form in establishes has tries harder the ribbed plate, the corresponding empty stomach component intensity and the rigidity greatly enhance, is suitable for 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 an empty web member for concrete. (2) Background technology [0002] At present, cast-in-place reinforced concrete hollow floor is a widely used floor structure, which has the advantages of fast construction speed, small structure height, flexible division of indoor areas and no ceiling decoration. There are various hollow tubes and boxes filled with lightweight permanent tire molds, which can be hollow or solid. For example, the patent number applied for by the applicant on March 10, 1999 is ZL99232921.3, the utility model patent named "Thin-walled tube for in-situ reinforced concrete filling", which consists of a hard thin-walled tube and two plugs. Used in hollow floor as a lightweight permanent tire mold. Another example is the application number 99115666.8 filed by the applicant on November 29, 1999, titled "Fiber-reinforced thin-walled box for in-situ reinforced concrete filling and its manufacturing method", and its thin-...

AI Technical Summary

Problems solved by technology

However, when this kind of thin-walled box is used as an empty core 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 construction efficiency of the hollow floor. , so the overall strength and rigidity of the hollow formwork are poor, and the phenomenon of rupture of the hollow formwork is prone to occur. Therefore, it is urgently needed to develop a new type of hollow formwork for concrete.
