Description
Technical Field
The utility model belongs to the equipment parts field for the tunnel especially relates to a half straight thread half sleeve of extrusion adjustable reinforcing bar length.
Background
In a tunnel structure, in order to ensure good stress state and overall performance of steel bars in a lining structure, a plurality of joints are required to be arranged to enable the steel bars to smoothly transition at the joints, and the positions of the joints are generally connected by steel bar connectors. If the reinforcing bar both ends all adopt present common reinforcing bar connector to connect, because the operation is inconvenient, reinforcing bar length is wayward, produces two kinds of problems easily: the length of the steel bar is too long, the steel bar deviates to the surrounding rock side, the thickness of a protective layer is too large, and the accident of plain concrete block falling is easy to occur, so that the driving safety is influenced; and secondly, the length of the steel bar is too short, the steel bar deviates to the clearance side, the steel bar leakage phenomenon is easy to occur, and then a row of problems such as corrosion of the steel bar is caused, and the structure safety is influenced.
And if reinforcing bar one end adopts reinforcing bar connector to connect, the ligature overlap joint is adopted to one end, and the reinforcing bar joint strength of ligature overlap joint is difficult for guaranteeing. Therefore, how to solve and fix in major structure reinforcing bar one end, the other end is convenient for reliably connect, still can not cause above-mentioned two kinds of condition to appear, and it is necessary to develop a half straight thread half extrusion adjustable steel bar length's sleeve, when satisfying the reliable connection of tunnel structure reinforcing bar, guarantees the suitable of its length, and then guarantee tunnel structure's operation safety.
Disclosure of Invention
The to-be-solved problem of the utility model is to provide a half straight thread half extrudees adjustable reinforcement length's sleeve, especially is fit for the reliable connection of the suitable and rather than joint department of guarantee tunnel structure reinforcing bar length.
In order to solve the technical problem, the utility model discloses a technical scheme is: the sleeve comprises a main structural steel bar and a connecting sleeve body, wherein the connecting sleeve body and the main structural steel bar are connected end to end at intervals to form a closed loop and are arranged in a tunnel, the connecting sleeve body is of a cylindrical tubular structure, a connecting sleeve extrusion end is arranged at one end of the inner side of the connecting sleeve body, a connecting sleeve straight thread end is arranged at the other end of the inner side of the connecting sleeve body, a separating steel plate is vertically arranged at the inner side of the connecting sleeve body and separates the connecting sleeve extrusion end from the connecting sleeve straight thread end, the main structural steel bar free end at one side of the connecting sleeve body is inserted into the connecting sleeve extrusion end, threads are arranged on the outer side wall of the main structural steel bar free end arranged at the other side of the connecting sleeve body, and threads are arranged on the inner side wall of the connecting sleeve straight thread end, in main part structure reinforcing bar one end screw in connecting sleeve straight thread end, be provided with fastening special-shaped nut on the lateral wall of connecting sleeve straight thread end and main part structure reinforcing bar junction.
Furthermore, the number of the main structural steel bars and the number of the connecting sleeve bodies are at least four.
Furthermore, an annular groove is formed in the outer side wall, close to one end of the extrusion end of the connecting sleeve, of the connecting sleeve body in the circumferential direction.
Further, the length of the extrusion end of the connecting sleeve is 1.5 times of the length of the straight thread end of the connecting sleeve.
In the use, tunnel structure short side wall one side major structure reinforcing bar one end is passed through the screw thread and is connected with the straight threaded end of adapter sleeve, and short side wall opposite side major structure reinforcing bar passes through the extruded form of external force and is connected with adapter sleeve extrusion end, and the reinforcing bar can adjust the length of anchor income adapter sleeve body as required, has effectively avoided because of the protective layer thickness that major structure reinforcing bar length overlength arouses too big and because of the lining that major structure reinforcing bar length excessiveness arouses leaks the muscle problem.
The length of the extrusion end of the connecting sleeve is 1.5 times of the length of the straight thread end of the connecting sleeve, so that the reliable connection between the main structure steel bar and the extrusion end of the connecting sleeve is ensured; and set up fastening special-shaped nut and be used for twisting reverse threaded sleeve at connecting sleeve screw thread end department, the major structure reinforcing bar of being convenient for is connected with connecting sleeve body structure.
The utility model has the advantages and positive effects that: due to the adoption of the technical scheme, make the utility model discloses a screw thread is connected with the straight thread end of connecting sleeve, and short side wall opposite side major structure reinforcing bar passes through the extruded form and the connecting sleeve extrusion end of external force and is connected, and the reinforcing bar can adjust the anchor as required and go into connecting sleeve's length, and easy to operate has effectively avoided leaking the muscle problem because of the protective layer thickness that reinforcing bar length overlength arouses is too big and because of the lining that reinforcing bar length short arouses. The special-shaped fastening nut is arranged at the threaded end of the connecting sleeve and used for twisting the threaded sleeve, so that the steel bar is connected with the sleeve structure conveniently. The middle position of the connecting sleeve is provided with a separating steel plate to divide the sleeve into two parts, so that the length of an effective connecting area of the extrusion end and the straight thread end of the connecting sleeve is ensured.
The invention well solves the safety problem existing at the position of the existing steel bar joint, and has the advantages of novel design concept, reasonable measures, obvious effect and wide application prospect.
