Problems solved by technology

However, when this kind of thin-walled box is used as a fasting 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. The floor has no reinforced structure, the strength and stiffness of the floor are relatively poor, and the ability to withstand concentrated loads is relatively low, especially when the size of the hollow formwork is large, it is more obvious

Embodiment Construction

[0060] The present invention will be further described below in conjunction with the drawings and embodiments.

[0061]The present invention, as shown in the accompanying drawings, includes a hollow form shell 1, which is characterized in that at least two hollow form shells 1 are arranged alternately. The opposite surfaces of the hollow form shell 1 form a cast-in-place concrete inner rib cavity 2 and an inner rib mold cavity. 2 has at least one spacer 3 that connects the open web form shells 1 on opposite or adjacent faces into a whole, and at least one groove 4 is provided on at least one surface of the open web form shell 1. figure 1 It is a schematic diagram of the structure of Embodiment 1 of the present invention. In the drawings, 1 is a hollow mold shell, 2 is an inner rib mold cavity, 3 is a spacer, 4 is a groove, and in the following drawings, the same number is the same, and the description is the same. Such as figure 1 As shown, two empty web mold shells 1 are arrang...

Abstract

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 (3) piece is arranged in the inner rib die cavity (2) for alternately integrating opposite or adjacent faces of the hollow shuttering (1), and a groove is arranged in at least one face of the hollow shuttering (1). The hollow component is convenient for positioning between each other when being applied to on-site casting hollow floor, as a result, the construction quality and efficiency are guaranteed, and the on-site casting concrete pier, pillar or reinforcing bar can be formed in the groove, so strength and rigidity of the floor are improved greatly. 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 an empty web member 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 structure height, flexible division of indoor areas and no ceiling decoration. There are various hollow tubes and boxes filled with lightweight permanent tire molds, and the boxes can be hollow or solid. For example, the patent number applied 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 i...
