Problems solved by technology

However, after this hollow thin-walled member is buckled into a whole, its integrity is not good, and its strength and rigidity are low. Especially for the hollow thin-walled member formed by the connection of male and female groove-type overlapping parts, half parts are easy to loosen and slip off. , the construction is inconvenient and affects the follow-up construction. Therefore, it is urgently needed to develop a new type of plastic thin-walled pipe

Embodiment Construction

[0073] The present invention will be further described below in conjunction with the drawings and embodiments.

[0074] As shown in the drawings, the present invention includes an annular thin-walled tube body 1 and a sealing plate 2. The sealing plate 2 closes the tube end of the annular thin-walled tube body 1 to form a closed hollow thin-walled tube. The annular thin-walled tube body 1 is composed of at least The two plates 3 are spliced ​​together, and the splicing part is connected to each other by the connecting piece 4, the connecting piece 4 is a male and female groove connecting piece, and the male strip 5 of the connecting piece 4 is inserted into the female groove 6 to connect to form a splicing strip 7, which is characterized by The said connector 4 is a non-slip male and female groove connector, the female groove 6 is provided with a non-slip member 8, and the inner cavity of the thin-walled tube 1 is provided with a detachable support rod ring 9, a support ring 10, A...

Abstract

A plastic thin wall tube includes a ring thin wall tube and a closer board, in which, said tube is spliced by two sheets and the spliced parts are connected by a connector, which is a male and a female one, the male strip is plug into the female slot to form a spliced strip characterizing that said connector is anti-surged, the anti-surged component is set on the female slot, a split support rod ring, a support ring, a support rod or a board is set horizontally along the wall in the tube and contacted with the inside of the wall and set with a notch on it laminated and fixed with the spliced strip.

Description

(1) Technical field [0001] The invention relates to a plastic thin-walled tube. (2) Background technology [0002] At present, in the prior art, the cast-in-situ reinforced concrete hollow slab hole-forming member is a permanent core mold, such as paper tube, plastic tube, metal corrugated tube, and light-weight core mold material. These tubular core molds or components are mainly considered to be evacuated to reduce the weight of the hollow slab. For example, the patent number applied by the applicant is ZL99249775.8 and the utility model patent named "fiber-reinforced thin-walled tube for in-situ reinforced concrete filling", which is composed of a hard thin-walled pipe and plugs at both ends, two plugs The two ends of the hard thin-walled tube are sealed to form a closed cavity. The wall of the hard thin-walled tube is composed of a matrix and a cementing material. The matrix can be glass fiber, carbon fiber, organic fiber, non-woven fabric or fiber For braid, the cementitious...
