Meanwhile, the thickness of the abutting part 1 along the axial direction of the steel bar to be adjusted is 20mm-40mm, so as to ensure that the tool can accurately position the bending position of the steel bar to be adjusted and thus implement adjustment. Of course, the utility model is not limited to this, the thickness of 20mm-40mm is only more suitable for adjusting the steel bar to be adjusted in the modular building, and the thickness of other sizes can also be selected according to actual needs by the person skilled in the art. The distance between the bottom of the arc-shaped groove 11 and the connection of the abutting part 1 and the force transmission rod 2 is greater than or equal to the radius of the force transmission rod 2, so as to ensure the strength of the abutting part 1 during use. The shape of the abutting part 1 can be adjusted according to actual needs, which can be a plane with an anti-skid structure or a grab type structure, as long as it can fit the steel bar to be adjusted and facilitate correction and straightening. In the embodiment, the thickness of the abutting part 1 along the axial direction of the steel bar to be adjusted is preferably 30mm, and the distance between the bottom of the arc-shaped groove 11 and the connection of the abutting part 1 and the force transmission rod 2 is preferably the radius value of the force transmission rod 2.

[0034] The end knocking surface of the knocking part 3 far from the abutting part 1 can be a plane or an arc surface or any form of surface that is convenient to knock and can provide sufficient knocking area. The force transmission rod 2 is connected to the middle part of the abutting part 1, and the projection profile of the abutting part 1 in the plane perpendicular to the force transmission rod 2 is located outside the projection profile of the force transmission rod 2 in the plane (that is, the cross-sectional size of the abutting part 1 is greater than the cross-sectional size of the force transmission rod 2). The force transmission rod 2 is also connected to the middle part of the knocking part 3, and the projection profile of the knocking part 3 in the plane perpendicular to the force transmission rod 2 is also located outside the projection profile of the force transmission rod 2 in the plane (that is, the cross-sectional size of the knocking part 3 is greater than the cross-sectional size of the force transmission rod 2). Therefore, the abutting part 1, the force transmission rod 2 and the knocking part 3 jointly form a H-shaped structure.

[0035] The knocking part 3 shown in the embodiment is a trapezoidal cylindrical structure or a square structure along the cross section parallel to the extension direction of the force transmission rod, and the end where the short side of the trapezoidal cross section is located is fixedly connected with the force transmission rod 2.

Of course, the utility model is not limited to this, and the above-mentioned support rod 21 can also be a plurality of support rods arranged along the circumferential direction of the force transmission rod 2. The arrangement of two support rods perpendicular to the axial direction of the steel bar to be adjusted in the embodiment is a better choice for better guaranteeing the strength under the premise of simplifying the structure.

[0037] In addition, the outer peripheral wall of the force transmission rod 2 shown in the embodiment is provided with an anti-skid portion 22 close to the knocking portion 3, the anti-skid portion 22 is a frosted anti-skid portion manufactured by adopting a frosted process or is an anti-skid portion formed by adding an anti-skid material to the outer peripheral wall of the force transmission rod 2. The anti-skid portion 22 is arranged in the first half region of the force transmission rod 2 close to the knocking portion 3, that is, close to the knocking portion 3, and the function of the anti-skid portion 22 is to facilitate workers to stably hold and use the tool in a wet or muddy construction site environment. Therefore, based on this function, the skilled person in the art can know that the anti-skid portion 22 should be arranged at a position more conducive to operation. At the same time, the length of the force transmission rod 2 can also be adjusted according to actual needs, so that it can meet the needs of workers to hold and operate, and save operation space as much as possible.

[0038] The abutting portion 1, the force transmission rod 2 and the knocking portion 3 of the tool are all made of high-strength metal materials, preferably high-strength alloy steel or high-chromium cast iron, etc. These high-strength metal materials can withstand high-frequency beating for a long time without deformation or damage, thereby better guaranteeing the service life of the tool.

[0039] When using the tool, the abutting portion 1 is attached to the steel bar to be adjusted, the worker holds the anti-skid rod portion of the tool (that is, the position of the force transmission rod 2 with the anti-skid portion 22), and knocks the force point (that is, the knocking surface position) at the end of the tool with a hammer, so that the steel bar is instantaneously straightened through force transmission, thereby realizing the positioning of the box.

[0040] The positioning steel bar calibration tool for fabricated building is simple in structure and flexible to use. When fine adjustment is needed, a smaller calibration tool can be used to facilitate the worker to hold the tool with one hand in a small space, and the other hand is used to control the hammer, thereby greatly improving the operation efficiency. When a larger degree of adjustment is needed, a larger calibration tool can be used, and two people can work together, one holds the tool with one hand, and the other uses a hammer to knock.
