[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a device for fixing anchor bolts, such as Figure 1 and 2 As shown, it includes an assembly template 1 and a connection component 3. The connection component 3 is used to relatively fix the assembly template 1 and the built steel frame 4. The assembly template 1 is used to mutually position multiple anchor bolts 2. The bottom of the anchor bolt 2 is deep into the steel frame 4. During the later pouring, the bottom end of the anchor bolt 2 will be buried in the concrete structure. There are six anchor bolts 2, which are arranged in a 2x3 manner, and the length direction of the anchor bolt 2 is the vertical direction.

[0023] like Figure 1 and 2 As shown, a scaffold 41 is fixedly mounted around the steel bar frame 4, and the connection assembly 3 includes a support rod 31, a clamping hoop 32 and a clamping block 33. The support rod 31 and the scaffold 41 are relatively fixed (the support rod 31 itself is also regarded as a part of the scaffold 41). There are two support rods 31, and the length directions of the support rods 31 are parallel to each other and are all in the horizontal direction. The assembly template 1 is located above the support rod 31, and its plate surface is a horizontal plane, and the lower plate surface abuts against the support rod 31; the clamping hoop 32 is sleeved on the support rod 31, and the clamping block 33 is fixedly connected to the clamping hoop 32, and the clamping block 33 abuts against the upper plate surface of the assembly template 1, that is, the support rod 31 achieves the clamping and fixing of the assembly template 1 through the clamping hoop 32 and the clamping block 33.

[0024] like Figure 1 and 2 As shown, the assembly template 1 is provided with a plurality of positioning holes 11 for the anchor bolts 2 to pass through, a single anchor bolt 2 passes through a positioning hole 11, the upper end of the anchor bolt 2 is threadedly connected with an assembly nut 21, the lower side of the assembly nut 21 abuts against the upper plate surface of the assembly template 1, and at this time, each anchor bolt 2 is "suspended" on the assembly template 1.

[0025] like Figure 1 and 3 As shown, in order to improve the relative stability of the anchor bolt 2 and the assembly template 1, an abutment block 22 is slidably provided on the side of the assembly template 1 away from the assembly nut 21 and located beside the anchor bolt 2. The sliding direction of the abutment block 22 is perpendicular to the length direction of the anchor bolt 2. There are two abutment blocks 22 beside a single anchor bolt 2, and the two abutment blocks 22 are respectively for the opposite sides of the anchor bolt 2. A control component 5 for controlling the movement of the abutment block 22 is provided on the assembly template 1, which can make the ends of the two abutment blocks 22 abut against the side wall of the anchor bolt 2 to clamp the anchor bolt 2. A polyurethane pad 222 is fixedly connected to the side of the abutment block 22 facing the anchor bolt 2, which has a low hardness and a certain flexibility to reduce damage to the thread structure of the anchor bolt 2.

[0026] like Figure 1 and 3 As shown, the control assembly 5 includes a control spring 52, a fixing cylinder 51 and a control nut 53. One end of the control spring 52 is connected to the abutment block 22, and the other end is connected to the assembly template 1. In a natural state, the control spring 52 applies a thrust to the abutment block 22 to move toward the anchor bolt 2. The fixing cylinder 51 is fixedly connected to the assembly template 1 and is coaxial with the positioning socket 11. The control nut 53 is coaxially threaded with the fixing cylinder 51. The end face of the control nut 53 is provided with a control wedge surface 531, and the abutment block 22 is provided with a force-bearing wedge surface 221. When the assembly template 1 and the anchor bolt 2 need to be relatively separated, the control nut 53 is rotated to move the control nut 53 upward, the control wedge surface 531 abuts against the force-bearing wedge surface 221, and the control nut 53 applies a thrust to the abutment block 22. This thrust causes the abutment block 22 to move away from the anchor bolt 2, thereby causing the abutment block 22 to leave the anchor bolt 2.

[0027] According to the strength requirement, after the assembly template 1 is built and each anchor bolt 2 is fixed, the bottom side wall of the anchor bolt 2 and the steel frame 4 can be reinforced and fixed by electric welding.

[0028] like Figure 2 As shown, the assembly template 1 is a steel plate with a thickness of more than 1 cm. In order to reduce its weight, a weight-reducing hole 12 is opened in the middle of the assembly template 1.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
