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, and 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.But, after this hollow thin-wall component is buckled into integral body, its globality is bad, intensity and rigidity are lower, the landing that gets loose easily of the hollow thin-wall component that connects and composes for the joining parts of male and female slot type particularly, half of parts, construction is inconvenient, influence follow-up construction, 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 characteristics such as good integrity, intensity height, rigidity are big, easy construction.

Solution of the present invention is on the basis of existing technology, comprise the 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, the annular thin wall body is spliced by at least two plates, the splicing position is connected to each other by connector, connector is the male and female groove connector, the public bar of connector inserts in female groove and connects, form the splicing bar, it is characterized in that described connector is anti-slip male and female groove connector, female groove is provided with anti-slip member; but the light-wall pipe intracoelomic cavity is provided with at least a in the support bar ring of split or bracing ring or support bar or the gripper shoe; and with the tube wall of thin-walled body in side contacts, along thin-walled body horizontally set, described support bar ring or bracing ring or support bar or gripper shoe are provided with the socket joint recess; the tube wall of socket joint indent is provided with reinforcing rib or locating piece, reinforcing rib or locating piece and with the superimposed build-in of socket joint recess.Like this, because connector is anti-slip male and female groove connector, female groove is provided with anti-slip member, thereby 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; Simultaneously, because but the light-wall pipe intracoelomic cavity is provided with at least a in the support bar ring of split or bracing ring or support bar or the gripper shoe, and with the tube wall of thin-walled body in side contacts, along thin-walled body horizontally set, described support bar ring, bracing ring, support bar or gripper shoe are provided with the socket joint recess, the tube wall of socket joint indent is provided with reinforcing rib or locating piece, and with the superimposed build-in of socket joint recess, thereby it is solid and reliable to be bonded to each other, be difficult for moving, guaranteed the quality of plastic thin-wall tube, thereby make plastic thin-wall tube in transportation, pile up, in carrying and the application installation process, be not prone to distortion or breakoff phenomenon, its globality is better, the intensity height, rigidity is big, thereby problems of the prior art have been solved, reached purpose of the present invention, in addition, it is simple that the present invention also has production, cost is low, the intensity height, convenient in carrying, characteristics such as freight is low, 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, and are specially adapted to hollow arch without beam and use.

Feature of the present invention is that also described support bar ring, bracing ring, support bar or gripper shoe are provided with the socket joint recess, and with splicing bar superimposed build-in.Like this, behind socket joint recess and the superimposed build-in of splicing bar, the socket joint recess will splice bar to be closed tightly and blocks, and the socket joint recess has played the fastening snap action, makes tube wall amalgamation position more not easily separated, can reduce the loss of plastic thin-wall tube effectively, improves the qualification rate of product.
