Problems solved by technology

However, after this hollow thin-walled component is buckled into a whole, its integrity is not good, especially for the hollow thin-walled component formed by the connection of male and female groove-type overlapping parts, half parts are easy to loosen and slip, which is inconvenient for construction and affects Follow-up construction, therefore, the development of a new type of plastic thin-walled pipe has been urgently needed

Embodiment Construction

[0078] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0079]As shown in the accompanying drawings, the present invention comprises an annular thin-walled pipe body 1 and a sealing plate 2. The sealing plate 2 closes the pipe end of the annular thin-walled pipe body 1 to form a closed hollow thin-walled pipe. The annular thin-walled pipe body 1 consists of at least Two plates 3 are spliced ​​together, and the splicing parts are connected to each other by connectors 4, the connectors 4 are male and female groove connectors, and the male strip 5 of the connector 4 is inserted into the female groove 6 for connection to form a splicing strip 7, which is characterized in that The connecting piece 4 is an anti-slip male and female groove connector, the female groove 6 is provided with an anti-slip component 8, and the splicing strip 7 has at least one male strip 5 or / and at least one female groove 6. In the attac...

Abstract

A plastic thin wall tube includes a ring thin wall tube body and a closer board closing the end of the tube body to form a close hollow thin wall tube, in which, said body is spliced by two sheets and the joint parts are connected by a connector, which is a male / female connector, the male one is plug into the female slot to form a spliced strip characterizing that: said connector is an anti-surged male / female slot one, the anti-surged component is set on the female slot and the spliced strip includes at least a male one or / and a female slot, thus the connection of the tube is firm.

Description

(1) Technical field [0001] The invention relates to a plastic thin-walled pipe. (2) Background technology [0002] At present, in the prior art, the hole-forming member of the cast-in-place reinforced concrete hollow slab is a permanent mandrel, such as a paper tube, a plastic tube, a metal bellows, and a mandrel made of lightweight materials. These tubular mandrels or components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. For example, the patent No. ZL99249775.8 applied by the applicant is a utility model patent named "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete". It consists of a hard thin-walled tube and plugs at both ends. The two ends of the hard thin-walled tube are closed to form a closed cavity. The hard thin-walled tube wall is composed of a carcass and a cementing material. The carcass can be glass fiber or carbon fiber or organic fiber or non-woven fabric or fiber For braided fabric...
