Problems solved by technology
The hole-forming components are usually hollow thin-walled tubes, such as paper tubes, cement tubes, etc., which have the disadvantages of poor strength, low deformation resistance, and poor vibration and deformation resistance. For this reason, the applicant's application number is 99115649.8 and the name is The invention patent of "fiber-reinforced hollow thin-walled pipe for filling reinforced concrete and its manufacturing method" discloses a hollow thin-walled pipe including a pipe body and a plug, and the two plugs seal both ends of the pipe body to form a closed cavity Thin-walled tubes have excellent properties such as high strength, deformation resistance, and vibration resistance, and are easy to manufacture, practical, economical, and easy to promote
However, after this kind of hollow thin-walled pipe is applied to the cast-in-place concrete hollow floor, a one-way hollow slab is formed, which has a large difference in vertical and horizontal stiffness and poor seismic performance. Separation, cracking or peeling off

Embodiment Construction
[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0057] As shown in the accompanying drawings, the present invention includes a pipe body 1 and a plug 2, and the two plugs 2 block the pipe body 1 to form a closed hollow tube, which is characterized in that at least one plug 2 of the hollow tube sinks into the pipe body A tube-end pelvic cavity 3 is formed in 1, and a superimposed layer 4 is arranged on the plug 2 in the pelvic cavity 3, and the reinforcement 5 in the tube body 1 and the reinforcement 5 in the plug 2 are anchored in the superimposed layer 4 at the same time. In each accompanying drawing, 1 is a tube body, 2 is a plug, 3 is a pelvic cavity, 4 is a superimposed layer, and 5 is a reinforcement. In the following drawings, those with the same number have the same description. Such as figure 1 As shown, it includes a tube body 1 and a plug 2. Two plugs 2 block the tube body 1 to form a clos...

The invention discloses a reinforced filling hollow pipe, which comprises pipe body (1), headband (2), pelvic cavity (3), overlapping layer (4) and reinforced object (5), wherein the headband (2) blocks the pipe body (1) to form closed hollow pipe; at least one headband (2) immerses in the pipe body (1) to form pelvic cavity (3); the overlapping layer (4) is set on the headband (2) in the pelvic cavity (3); the reinforced object (5) in the pipe body (1) and headband (2) is anchored in the overlapping layer (4). The cast-in-place reinforced concrete enters into the pelvic cavity to form transverse reinforced rib with the headband, which reduces the transverse and longitude rigidity difference to improve the aseismic behavior. The invention prevents the segregating, crack or dropping phenomenon, which is fit for cast-in-place reinforced concrete or prestressed reinforced concrete hollow structure.
Description
(1) Technical field [0001] The invention relates to a hollow pipe for concrete filling. (2) Background technology [0002] At present, the cast-in-situ concrete hollow floor is more and more widely used due to its advantages of fast construction, low formwork loss, large bays, flexible partitions, and low self-weight. The hole-forming components are usually hollow thin-walled tubes, such as paper tubes, cement tubes, etc., which have the disadvantages of poor strength, low deformation resistance, and poor vibration and deformation resistance. For this reason, the applicant's application number is 99115649.8 and the name is The invention patent of "fiber-reinforced hollow thin-walled pipe for filling reinforced concrete and its manufacturing method" discloses a hollow thin-walled pipe including a pipe body and a plug, and the two plugs seal both ends of the pipe body to form a closed cavity The thin-walled tube has excellent properties such as high strength, deformation resi...
