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 efficiency of the hollow floor. The force-bearing and force-transmitting components of the cover, especially when the size of the hollow formwork is large, are more obvious. Therefore, it is urgent to develop a new type of hollow component for concrete.

Embodiment Construction

[0062] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0063] 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 3 that connects the opposite hollow formwork 1 alternately into one, and at least one hole 4 for pouring in-situ concrete is arranged on the hollow formwork 1 to run through the surface of the hollow formwork 1 . 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 cavity, 3 is a spacer brace, and 4 is a hole. In each accompanying drawing, those with the same number have the same description. As shown in Fig...

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 spacing 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 there is at least one hole for on-site casting concrete on the hollow shuttering (1). The hollow component is convenient for positioning 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 is cast into the hole of the hollow shuttering to form on-site casting concrete column or pillar, so the mechanical properties of the floor can be 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 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 ...
