Problems solved by technology

In this way, the half part can be formed in the mold at one time, and its production is simple, convenient, and low in cost. Small, large transportation volume each time, greatly facilitates handling, reduces transportation costs, and correspondingly reduces construction costs of cast-in-place reinforced concrete hollow slabs. However, when this hollow thin-walled member is assembled on site, it is composed of two half parts. It is not convenient to fit and fix, the number of components is large, and there are many procedures for preparation and assembly, and the corresponding production cost is high. deformation, or the phenomenon of pipe rupture, therefore, it is urgently needed to develop a new type of plastic thin-walled pipe

Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064] As shown in the accompanying drawings, the present invention includes an annular thin-walled pipe body 1 and a sealing plate 2, and the sealing plate 2 closes the pipe end of the annular thin-walled pipe body 1 to form a closed hollow thin-walled pipe, which is characterized in that the annular thin-walled pipe body The wall pipe body 1 is formed by rolling a plate 3 into a circular splicing, and the splicing parts are connected to each other by the connector 4 to form a longitudinal splicing strip 5. The inner cavity of the thin-walled pipe body 1 is provided with a separable support rod ring 6 or At least one of the support ring 7 or the support rod 8 or the support plate 9 is in contact with the inner side of the tube wall of the thin-walled pipe body 1, and is arranged laterally along the thin-walled pipe body 1. The support rod ring 6, the su...

Abstract

A plastic thin wall tube includes a ring thin wall tube and a closer board closing the end of the tube to form a close hollow thin wall tube characterizing that said tube is spliced by rolling a sheet to a ring, the joint parts are connected by a connector to form a longitudinal spliced strip, the inner cavity of the tube is set with a slit support rod ring, a support ring, a support rod or a support board, which is horizontal along the tube and has a plug notch and a reinforcing rib or allocation block is set on the notch to be stacked with it suitable for various hollow boards, hollow floors, roofs and foundation base plates.

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...
