Description

A kind of plastic thin-wall tube

(1) technical field

The present invention relates to a kind of plastic thin-wall tube.

(2) background technology

At present, in the prior art, it is permanent core that cast-in-situ reinforcing steel bar concrete hollow slab becomes pole, as paper tube, plastic pipe, metal bellows, core light material etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate hollowcore slab weight.The patent No. as applicant's application is that ZL99249775.8, name are called the utility model patent of " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder ", it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, this hard thin-wall tube wall is composited by carcass and cementitious materials, carcass can be glass fiber or carbon fiber or organic fiber or nonwoven or fibrous braid, and cementitious materials can be cement or organic resin or is the mixture of cement, filler, Admixture, fiber.This kind pipe has advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.But this thin wall cylinder light-wall pipe as a whole, it is big to take up room in transportation, and the quantity of each transportation is few, and the freight height has increased the construction cost of cast-in-situ reinforcing steel bar concrete hollow slab undoubtedly.For this reason, the applicant on December 22nd, 2002 applied for that application number is 02158266.1, name is called the application for a patent for invention of " a kind of cast-in-situ reinforced concrete member ", this kind member is that two half of parts are fastened to form, half of parts can be improved plastics structural shape, in the end of member the baffle plate shutoff is arranged, on at least one half of parts, the joining parts are arranged, be fixed into integral body, can form hollow thin-wall component by the joining parts.Like this, half of parts can disposablely make at in-mold molding, it produces simple, convenient, cost is low, simultaneously, this member can be assembled by half of position etc. at the construction field (site), thereby each parts occupation space in transportation is little, and each freight volume is big, greatly facilitates carrying, reduced freight, the corresponding construction cost that reduces cast-in-situ reinforcing steel bar concrete hollow slab, still, when this hollow thin-wall component is assembled at the scene, be fastened and inconvenience by two half of parts, the quantity of parts is many, its preparation, the operation of assembling is also many, corresponding production cost height, therefore, develop a kind of novel plastic thin-wall tube for being badly in need of.

(3) summary of the invention

The object of the present invention is to provide a kind of plastic thin-wall tube, have simple in structure, characteristics such as production is easy, cost is low, good integrity, intensity height.

Solution of the present invention is on the basis of existing technology, comprise annular thin wall body, hush panel, the pipe end of hush panel closed ring thin-walled body, form the hollow thin-wall pipe of sealing, it is characterized in that described annular thin wall body is intervolved to circularize by a plate is spliced, the splicing position is connected to each other by connector, forms longitudinal spliced, and the plate of thin-walled body is or/and contain reinforce in the hush panel.Like this, because the annular thin wall body is intervolved to circularize by a plate and is spliced, when light-wall pipe was assembled at the construction field (site), parts were simple, preparation is few, assembling is easy, thereby had characteristics such as simple in structure, that production is easy, cost is low; Simultaneously, because the plate of thin-walled body is or/and contain reinforce in the hush panel, reinforce can improve the plate of thin-walled body or the intensity of hush panel greatly, make its tension, resistance to compression, shear resistance is better, thereby can increase substantially the total quality and the bulk strength of light-wall pipe, thereby problems of the prior art have been solved, reached purpose of the present invention, in addition; light-wall pipe also has convenient in carrying; freight is low; characteristics such as construction application is convenient; be applicable to the hollowcore slab of various cast-in-situ reinforced concretes or prestressed reinforced concrete; hollow building cover; roof system; sole plate; body of wall and hollow bridges are used, be specially adapted to hollow arch without beam and use.

Feature of the present invention is that also described connector is anti-slip male and female groove connector, and the public bar of connector inserts in female groove and connects, and female groove is provided with anti-slip member.Like this, the connection of plastic thin-wall tube is firm, and public bar can slippage from female groove, good integrity, and during construction, carrying is laid convenient, does not influence follow-up construction.
