Description
(1) technical field
The present invention relates to a kind of tool for shaping hollow tube of reinforced concrete.
(2) background technology
At present, in numerous buildings, the frame structure of large span, large bay has adopted cast-in-place hollow arch without beam technology, have the reduction of erection time, reduce cost, improve building usage space, reduce advantages such as deadweight, anti-seismic performance are good.And employed one-tenth pole is permanent core in the arch without beam, as paper tube, plastic tube, metal hollow pipe, horniness thin-walled tube etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate floor weight.Wherein paper tube, plastic tube, metal hollow pipe etc. are higher because of cost, thereby reality is seldom used.At present, what the overwhelming majority was used in engineering is horniness thin-walled tube, as the patent No. is ZL99249755.8 " 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 end plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, and horniness thin-walled tube cross section and plug shape can be circle, square, trapezoidal or other is special-shaped.This kind fiber reinforcement type thin wall cylinder, its preparation method can adopt Wrapping formed method, and is Wrapping formed on movable tubular internal mold, after the Wrapping formed demoulding of body, the shutoff mouth of pipe covered in the single or multiple lift fiber stringing outsourcing of band cement mortar, is finished product.Also can manage the fibrous composite that paves in external mold or the half of pipe internal mold at one side of something; the demoulding obtains half of pipe after the maintenance; then the pipe end of two half of pipes is placed the bulkhead joint and carry out the joint close processing; and the formation horniness thin-walled tube; perhaps the two halves pipe is engaged earlier and carry out the joint close processing, then use the bulkhead shutoff mouth of pipe all can again.The light-wall pipe that adopts above-mentioned movable tubular internal mold to make, because of the prefabricated two ends plug that bonds again of light-wall pipe elder generation, thereby the phenomenon that exists the pipe end plug in transportation, transhipment, construction and installation process, to be easy to drop, adhesion strength is not high, and globality is poor, and production efficiency is low.And adopt one side of something pipe external mold or the half of pipe of half of pipe internal mold making earlier, and again horniness thin-walled tube is made in the two halves tube seam, also be prone to phenomenon seam crossing cracking, destruction; equally, its adhesion strength is not high, and globality is relatively poor; production efficiency is lower, and manufacture craft is too complicated.Trace it to its cause, be that above-mentioned mould has restricted technology, influenced the quality of light-wall pipe, therefore, develop a kind of novel tool for shaping hollow tube for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of tool for shaping hollow tube, have simple in structure, cost is low, characteristics such as easy to use, simultaneously, but has characteristics such as intensity height, good integrity one-shot forming, production efficiency height with the hollow pipe that it is made.
Solution of the present invention is that it comprises two interface limits, open and close type elasticity tube, shape keeping piece, clamp part, the interface limit is fixed on the open and close type elasticity tube wall limit along its length, shape keeping piece is wrapped in the end of open and close type elasticity tube, and clamp part is locked on the interface limit or holds tightly on open and close type elasticity tube.Like this, tool for shaping hollow tube in use, unclamp clamp part, open and close type elasticity tube trails, fibrous composite slip thereon paves, bulkhead is put at two ends, then with the open and close type elasticity tube parcel shape keeping piece that trails, buckle clamp part, maintenance is to the stipulated time, and the demoulding gets final product, but hollow pipe intensity height, good integrity one-shot forming, the production efficiency height made like this, overall dimensions are accurate, joint strength is high, and mould itself is simple in structure, cost is low, easy to use, thereby reached purpose of the present invention.
