Technical Field
The utility model relates to a bellows construction and installation technical field specifically is a sleeve pipe device for bellows joint.
Background
The corrugated pipe is embedded in the prefabricated box girder and penetrates through the prefabricated box girder. And steel strands penetrate into the corrugated pipe, and are pulled to prevent the concrete from collapsing. In the process, because the box girder has a large volume and the common corrugated pipes cannot reach the length of the box girder, the end parts of the plurality of sections of corrugated pipes are bound with each other to reach the length of the box girder.
The bundled corrugated pipes are positioned in the box girder, then concrete is poured into the box girder, and finally the concrete is tamped by a tamping rod; however, the prior corrugated pipe has the following problems in the use process: firstly, in the process of tamping concrete, the corrugated pipes are likely to be touched, and when the corrugated pipes are touched and shake, the binding between the adjacent corrugated pipes is loosened, so that the concrete in the box girder flows into the corrugated pipes, the corrugated pipes are blocked, and the steel stranded wires cannot pass through the corrugated pipes; in addition, because the joint strength of the corrugated pipe joint is low, the corrugated pipe joint is easily extruded and deformed in the concrete tamping process, so that the steel strand cannot smoothly pass through the corrugated pipe joint.

An object of the utility model is to foretell not enough, provide one kind and can make the connection between adjacent bellows more firm reliable, can also effectively strengthen the sleeve pipe device for bellows coupling of the joint strength of bellows junction.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a bushing apparatus for bellows connection, locates including adapter sleeve and cover the enhancement sleeve outside the adapter sleeve, the left end of adapter sleeve is provided with left side annular groove and left side heat-shrinkable sleeve, and the right-hand member of adapter sleeve is provided with right side annular groove and right side heat-shrinkable sleeve, left side heat-shrinkable sleeve and right side heat-shrinkable sleeve are close to respectively enhancement sleeve's inside wall setting, be provided with two sets of heating element on the inner wall of enhancement sleeve, heating element is just right respectively left side heat-shrinkable sleeve and right side heat-shrinkable sleeve set up.
Furthermore, a storage battery is arranged in the connecting sleeve and is electrically connected with the heating assembly.
Further, heating element is including inlaying locate strengthen heater strip and temperature sensitive switch on the sleeve pipe inner wall, heater strip electric connection the temperature sensitive switch.
Further, the left side heat-shrinkable sleeve and the right side heat-shrinkable sleeve are both made of a heat-shrinkable material.
Further, the reinforcing sleeve is made of a high-strength material.
The utility model has the advantages that:
in practical application, the end parts of the two corrugated pipes are respectively abutted into the left annular groove and the right annular groove, and the left heat-shrinkable sleeve and the right heat-shrinkable sleeve are respectively heated by the two groups of heating assemblies, so that the left heat-shrinkable sleeve and the right heat-shrinkable sleeve are heated and shrunk and then cling to the outer sides of the corrugated pipes; the connection strength of the corrugated pipe connection part can be effectively improved through the reinforcing sleeve; the utility model discloses can make the connection between adjacent bellows more firm reliable, can also effectively strengthen the joint strength of bellows junction.
