Problems solved by technology

However, after this kind of thin-walled pipe is applied to the space floor, the two plugs only play the role of sealing the nozzle, and cannot bear the complex tension, pressure, and torque along the transverse direction of the pipe in the space floor. The phenomenon of cracking and damage to the head will affect the service life of the floor. Therefore, it is urgently needed to develop a new type of thin-walled concrete hollow pipe.

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] As shown in the drawings, the present invention includes a pipe wall 1 and two plugs 2, and is characterized in that at least one thin strip 3 is clamped inside the plugs 2. Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a pipe wall, 2 is a plug, and 3 is a thin strip, and those with the same number have the same description. In Fig. 1, two thin strips 3 are clamped in the plug 2.

[0049] The present invention is also characterized in that a stiffening rib 5 or a stiffening rod 6 or both are arranged in the closed cavity 4 surrounded by the pipe wall 1 and the two plugs 2 . FIG. 2 is a schematic structural view of Embodiment 2 of the present invention, in which a solid stiffener 5 , a hollow stiffener 6 and a solid stiffener 6 are arranged in the cavity 4 .

Abstract

A thin-wall hollow pipe for in-situ pouring bar reinforced non-beam concrete floor is composed of pipe wall and two end plugs, and is characterized by that each end plug has at least one thin strip for improving its tension, tension and compression resistance. Its advantages are simple structure, high strength, high crack, deformation and vibration resistance and low cost.

Description

(1) Technical field [0001] The invention relates to a thin-walled pipe for hollow concrete. (2) Background technology [0002] Thin-walled pipes for filling cast-in-place reinforced concrete have been widely used in cast-in-place concrete hollow floors due to their advantages such as convenient construction and transportation, sound insulation, and good sealing performance. But because most of the existing thin-walled pipe walls adopt a single structure, its strength is not high, its resistance to deformation is poor, and its resistance to vibration damage is not good. For this reason, the applicant applied for a patent on November 22, 1999. ZL99249755.8, a utility model patent named "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and two plugs, and the two plugs connect the two ends of the hard thin-walled tube Closed to form a closed cavity, the hard thin-walled pipe wall is composed of a carcass...
