Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for correcting the bending degree of steel bars at a pile head. Background Art

[0002] In the construction field, most construction units will involve the binding of foundation steel bars when carrying out foundation engineering construction. However, after the foundation pit is excavated and the pile heads are removed, some of the pile head steel bars will be bent too much. At this time, the column head steel bars need to be corrected.

[0003] In the prior art, the method for correcting the column head steel bars is generally that construction workers use hollow steel pipes as tools to correct the bending of the steel bars for straightening. However, this method still has problems. When the curvature of the pile head steel bars is too large, the use of steel pipes as correction tools cannot effectively correct the curvature of the steel bars, and there is even no force point for correcting the pile head steel bars, which has a certain impact on the subsequent binding of the foundation steel bars. Secondly, due to the weak lateral shear resistance of the pile head steel bars, the use of steel pipes for forced rapid correction is prone to brittle fracture of the steel bars, affecting the quality of the project and the overall construction progress. This approach will not only reduce the working efficiency of the construction workers, but also pose certain safety hazards, and it is difficult to ensure that the construction quality meets the standards. Therefore, a pile head steel bar curvature correction device is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a device for correcting the curvature of pile head steel bars, which replaces the traditional brutal correction method of ordinary steel pipes and allows operators to perform steel bar straightening work more simply and safely.

[0005] The technical solution for achieving the purpose of the utility model is: a device for correcting the curvature of steel bars at a pile head, comprising a fixed block, wherein there are multiple fixed blocks, and each two of the fixed blocks are movably connected via a hinge, and a fixed bottom block is welded and fixed on one side of each of the fixed blocks, and an adjustable steel bar fastening block is provided on one side of the fixed bottom block.

[0006] In some embodiments, a connecting hole is opened through the fixed bottom block, and an adjustment screw and a light rod are respectively arranged in the connecting hole. One end of the adjustment screw is rotatably connected to one side of the fixed block, and one end of the light rod is fixedly connected to one side of the fixed block. The adjustment screw and the light rod are diagonally distributed.

[0007] In some embodiments, the adjustable steel bar fastening block is provided with a threaded hole and a sliding hole at corresponding positions of the connecting hole, the inner wall of the sliding hole is slidably connected to the surface of the polished rod, and the inner wall of the threaded hole is threadedly connected to the adjusting screw.

[0008] Compared with the prior art, the utility model has the following significant advantages:

[0009] Firstly, the utility model fixes the fixed block in the middle of the device at the upper bending point of the steel bar by using the fixed bottom block and the adjustable steel bar fastening block, and rotates the hinge, so that the fixed blocks in other positions can also be fixed tightly to the steel bar in the same way, and then the hydraulic rod is used to pressurize the fixed block to achieve the straightening effect, which replaces the traditional barbaric straightening method of ordinary steel pipes, and solves the problems of low working efficiency of construction workers, high safety hazards, and poor quality assurance.

[0010] Secondly, the utility model provides a fixed bottom block and an adjustable steel bar fastening block, and by rotating the adjusting screw during use, the distance between the fixed bottom block and the adjustable steel bar fastening block can be adjusted according to the steel bars that need to be straightened, thereby greatly enhancing the applicability and turnover of the device. At the same time, the device is small in size, easy to carry, and has stronger practicality.

[0011] The invention solves the problems that the existing steel bar straightening method is inconvenient to use, has strong limitations, has certain safety hazards, and is difficult to ensure that the construction quality meets the standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a pile head steel bar bending correction device through improvement. The technical solution of the utility model is:

[0019] like Figure 1As shown, a device for correcting the curvature of a pile head steel bar comprises a fixed block 1. There are a plurality of fixed blocks 1. Every two fixed blocks 1 are movably connected via a hinge. Due to the different degrees of bending of the steel bars, the hinge can adapt to different steel bar curvature conditions, making the device more practical. A fixed bottom block 2 is welded and fixed on one side of each fixed block 1. An adjustable steel bar fastening block 3 is provided on one side of the fixed bottom block 2. An elliptical area for accommodating the steel bars can be formed between the adjustable steel bar fastening block 3 and the fixed bottom block 2.

[0020] like Figure 2 As shown, in one embodiment, a connecting hole is opened through the fixed bottom block 2, and an adjusting screw 4 and a light rod 5 are respectively arranged in the connecting hole. There is no connection between the fixed bottom block 2 and the adjusting screw 4. The connecting hole passes through the fixed bottom block 2 and is only used for communication. One end of the adjusting screw 4 is rotatably connected to one side of the fixed block 1, and one end of the light rod 5 is fixedly connected to one side of the fixed block 1. The adjusting screw 4 and the light rod 5 are diagonally distributed. The diagonally distributed adjusting screw 4 can make the force on the fixed block 1 more uniform when the straightening work is carried out and the load is applied, so as to prevent cracking.

[0021] The adjustable steel bar fastening block 3 is provided with a threaded hole and a sliding hole at the corresponding positions of the connecting hole. The positions of the threaded hole and the sliding hole correspond to the positions of the polished rod 5 and the adjusting screw 4 respectively. The inner wall of the sliding hole is slidingly connected to the surface of the polished rod 5, and the inner wall of the threaded hole is threadedly connected to the adjusting screw 4.

[0022] The specific working method is: when the pile head steel bar curvature correction device is used, first, the spacing between the fixed bottom block 2 and the adjustable steel bar fastening block 3 is adjusted according to the steel bars that need to be straightened. The specific operation is to rotate the adjusting screw 4. Under the action of the thread, the distance between the two will gradually move away or closer, and finally the steel bar can be tightly embraced by the fixed bottom block 2 and the adjustable steel bar fastening block 3 to achieve a fixing effect. Then, the fixed block 1 in the middle of the device is fixed at the upper bending point of the steel bar using the fixed bottom block 2 and the adjustable steel bar fastening block 3, and the hinge is rotated so that the fixed blocks 1 in other positions can also be tightly fixed to the steel bar in the same way. After completing the above steps, use a hydraulic rod to pressurize the fixed block 1 until the curvature of the pile head steel bar reaches an ideal state.

[0023] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
