Abstract
A sleeve-type wire connector comprises a steel sleeve, a hollow bolt and wire anchors. The sleeve-type wire connector is characterized in that round holes allowing steel wires to pass through are formed along the steel sleeve and the axle of the hollow bolt; a threaded hole matched with the hollow bolt in diameter is also formed at the front segment of the steel sleeve; the steel wire penetrates the hollow bolt and the steel sleeve respectively; and the two wire anchors and the hollow bolt are screwed in to achieve wire connection. After the pre-stress of a prefabricated girder plate is tensioned, the next connection can be conducted by unscrewing the hollow bolt and the taking out the steel wire in the holes. The steel wire in the steel sleeve can be kept and reused, thereby effectively reducing the length of waste pre-stress wires. The sleeve-type wire connector has the advantages of simple processing, easy operation and good wire saving effect, and is useful for reference for similar engineering.
Description
Technical field
The utility model relates to the realm of building construction, specifically a kind of wiring connector of using of prestressing force pre-tensioning system precast concrete beam slab.
Background technology
Along with the development of communication, prestressing force pre-tensioning system precast concrete beam slab is all adopted in various medium and small designs of striding the footpath bridge, and is many with hollow beam slab.During on-the-spot precast beam in batches,, all need reserve the operating space more than 3 meters at the two ends of stretching bed seat owing to remove the needs of beam body internal mold.By the time after the concreting of every groove precast beam is finished and is reached respective strengths, carry out prestressing force when putting, generally all cut off steel wire in the precast beam end, cause the discarded steel wire of reservation operations space segment long like this.The prestressing force guiding principle silk arrangement of reinforcement of opening beam slab earlier is many, and the compressor wire price is also high, takes care of the pence, and for the beam making field of a production in enormous quantities, a no small waste is unfavorable for reducing construction costs really.
Summary of the invention
Deficiency at above-mentioned pre-tensioning system precast beam, in order to save the discarded length of stretching bed seat two ends headspace section compressor wire effectively, the utility model provides a kind of telescopic wiring connector, it is by steel bushing, hollow bolt, the steel wire pier nose is formed, it is characterized in that: the axle center along steel bushing and hollow bolt is equipped with the circular hole that can penetrate steel wire, preceding half section of steel bushing also is provided with and its screwed hole that is complementary of hollow bolt diameter, two sections steel wires are penetrated respectively in hollow bolt and the steel bushing, screw in the connection that steel bushing is finished steel wire by two steel wire pier noses and hollow bolt.
Steel bushing should select for use diameter to make than steel wire big 5 times but the round steel that do not exceed precast beam steel wire spacing (in order to avoid influence compressor wire location), and length is taken the circumstances into consideration intercepting according to stressed.
The rear end of hollow bolt is provided with the hexagonal (hexagon)nut identical with the steel bushing diameter, so that craft or use spanner screw in it in screwed hole of steel bushing.
When prestressing force is put, after the end of precast beam cuts off steel wire, screw out hollow bolt, take out steel wire in the bolt hole, hollow bolt can carry out next circulation and connect.Steel bushing to the steel wire of stretch-drawing beam section then can keep and reuse, thereby can reduce the length of discarded compressor wire effectively.Formerly the long collimation method of Zhang Liang prefabricated in, even by hundred meters long stretching bed seats, its steel wire is saved can not be lower than 5% yet.The utility model processing is simple, easy operating, saving steel wire effect are obvious, can use for reference for similar engineering.
Description of drawings
Fig. 1 is the utility model schematic diagram
Fig. 2 is the utility model implementation process schematic diagram
The specific embodiment
As depicted in figs. 1 and 2, the symbol among the figure: the 1st, steel bushing, the 2nd, hollow bolt, the 3rd, steel wire, the 4th, steel wire pier nose, the 5th, stretching bed seat, the 6th, precast beam, the 7th, stretch-draw end, the 8th, fixed end.
According to the length and the wiring connector relevant position, two ends of stretching bed seat 5, accurately intercept the length of every section compressor wire 3, pier is slightly inserted the steel wire pier nose 4 on stretch-draw end 7 and fixed end 8 crossbeams well simultaneously.To lean on stretch-draw end 7 then and lean on the steel wire 3 of fixed end 8 to penetrate steel bushing 1, to lean on the steel wire 3 of precast beam end to penetrate hollow bolt 2 again, respectively the steel wire head pier is slightly become steel wire pier nose 4 with pier protective device subsequently, again hollow bolt 2 is screwed in steel bushing 1 accordingly at last, finish steel wire and connect.Treat precast beam 6 reach put Zhang Qiangdu after, cut off steel wire 3 in the precast beam termination, screw out hollow bolt 2 and take out steel wire in the hole, carry out the connection of next circulation.
Claims (3)
