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 size, 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 parts is large, and there are many processes for preparation and assembly, and the corresponding production cost is high. The hollow thin-walled member formed by the connection of groove-type overlapping parts, half parts are easy to loosen and slip off, which is inconvenient for construction and affects subsequent construction. Therefore, it is urgently needed to develop a new type of plastic thin-walled pipe.

Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] 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 piece of plate 3 into a circular splicing. The splicing parts are connected to each other by a connecting piece 4 to form a longitudinal splicing strip 5. The connecting piece 4 is a male and female groove connecting piece that prevents slipping. 6 is inserted into the female groove 7 for connection, and the female groove 7 is provided with an anti-slip component 8 . In each drawing, 1 is an annular thin-walled pipe body, 2 is a sealing plate, 3 is a plate, 4 is a connecting piece, 5 is a sp...

Abstract

A plastic material thin-walled tube includes annular thin-walled tube, top seal plate for sealing tube end to form hollow thin-walled tube, featuring said body split-joined by a rolled sheet and connected to form longitudinal splice strip, connecting piece being a male threaded trough connector whose male strip pluging into releasing proof member in female threaded trough. Said invention has advantages of easy assembling, simple structure, and low cost, can be used in various kinds of cast-in-situ steel reinforcement concrete hollow slab, hollow building cover, and house cap etc.

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...
