[0029] As shown in FIG. 1, the auxiliary positioning plate 1 is made of a material that is not easy to deform, which can be a steel plate, an aluminum alloy plate, a polymer plate, or a glass steel plate. The diameter of the positioning hole 11 can be adapted to an M3.5 bolt or an M4 bolt. The spacing between adjacent positioning holes 11 is the same, which is 10 mm.

The center positioning hole 11 is numbered 0, and the other positioning holes 11 along the vertical direction of the center positioning hole 11 are numbered sequentially. The numbering divides the auxiliary positioning plate 1 into four parts. According to the numbering, the position of each positioning hole 11 can be located, and the spacing between the embedded bolts can be quickly positioned when the embedded bolts are fixed subsequently. Figure 3As shown, the tail of the connecting bolt 21 is welded with the cross plate 2, one connecting bolt 21 is arranged in the middle of the cross plate 2, the interval between adjacent connecting bolts 21 is the same, and the interval between adjacent connecting bolts 21 is preferably 20mm, that is, a certain interval is provided between the positioning holes 11 and the connecting bolt 21 is inserted.

[0030] The top of the connecting bolt 21 is provided with a gasket 22, which is sleeved into the gasket 22 after the top of the connecting bolt 21 passes through the positioning hole 11. The gasket 22 is attached to the top surface of the auxiliary positioning plate 1. Then the positioning nut 23 is screwed on the connecting bolt 21, the positioning nut 23 is attached to the top of the gasket 22, and the connecting bolt 21 and the cross plate 2 are fixed on the auxiliary positioning plate 1. The use of multiple connecting bolts 21 to position the cross plate 2 can make the bearing capacity of the cross plate 2 larger, and reduce the situation that the connecting bolt 21 is separated or broken during the movement of the embedded bolt connection with large size and weight.

[0031] The fixed sleeve 3 is welded to the center of the bottom of the cross plate 2, and the center of the fixed sleeve 3 is on the same axis as the connecting bolt 21 in the middle of the cross plate 2.

[0032] The top of the fixed bolt 4 is screwed into the fixed sleeve 3, and the height of the bolt clamp 5 can be adjusted by rotating the fixed bolt 4, and further the height of the embedded bolt can be adjusted.

[0033] The bolt clamp 5 is used to clamp the embedded bolt, the bottom of the bolt clamp 5 is an operating shaft 51, the lower part of the operating shaft 51 is provided with three slips 52, the outer side of the slip 52 is a conical curved surface, the top of the slip 52 is slidingly connected to the slide rail piece 53, the slip 52 slides inward to tighten the bottom space, and the embedded bolt can be fixed. Because the slip 52 can slide, various types of embedded bolts can be fixed, thereby enhancing the application range of the device, the slide rail piece 53 is fixedly connected to the bottom of the operating shaft 51, the outer side of the slip 52 is slidingly connected with a tightening shell 54, the tightening shell 54 is in the shape of a truncated cone as a whole, the bottom of the tightening shell 54 is screwed into the operating shaft 51, and a spring 521 is arranged between adjacent slips 52, which drives the slip 52 to move in the expansion direction. In use, the embedded bolt passes through the slip 52, and then the tightening shell 54 is twisted to move upward, thereby driving the slip 52 to contract and clamp the embedded bolt; when the bolt clamp 5 is removed, the tightening shell 54 is twisted to move downward, so that the slip 52 expands between them, so that the embedded bolt is separated from the slip 52. The embedded bolt is on the same axis as the connecting bolt 21 in the middle of the cross plate 2, and the position of the embedded bolt can be positioned by the connecting bolt 21.

[0034] Two horizontal bubbles 6 are arranged on the adjacent two sides of the auxiliary positioning plate 1. In use, the auxiliary positioning plate 1 is placed on the reinforcing bar, and the horizontal bubble 6 is adjusted to be horizontal by the way of cushioning block, so that the auxiliary positioning plate 1 is arranged horizontally, thereby unifying the height of the embedded bolt.

[0035] Example 2:

When the auxiliary positioning plate 1 is leveled, the extension rod 72 is rotated and extended, and after leveling, the supporting leg 73 is inserted into the ground around the periphery to be fixed.

[0038] The positioning sheet 71 is provided with a sliding channel 711, the bottom of the sliding channel 711 is provided with a shaft groove 712 and a locking sheet 713, the top of the extension rod 72 is provided with a rotating shaft 721, the rotating shaft 721 is rotatably connected to the shaft groove 712, the locking sheet 713 is slidably connected to the bottom of the sliding channel 711, and the locking sheet 713 is arranged above the rotating shaft 721. When the extension rod 72 is needed to be used, the rotating shaft 721 is slid into the sliding channel 711, the rotating shaft 721 is placed in the shaft groove 712, and then the locking sheet 713 is slid to cover the rotating shaft 721, so that the rotating shaft 721 will not be separated from the shaft groove 712 during use; when disassembled, the locking sheet 713 is slid backward, and the rotating shaft 721 is lifted upward to be separated from the sliding channel 711.

[0039] The use principle of the device is as follows:

[0040] According to the existing drawings, the size and center distance of the embedded bolt are determined, and taking the center distance of the M30 bolt as 300mm×200mm as an example, the positioning holes 11 of the "15" and "10" marks are found in two vertical directions on the auxiliary positioning plate 1. First, the bolt clamp 5 is connected with the embedded bolt, and then the center connecting bolt 21 of the top cross plate 2 of the bolt clamp 5 is aligned with the positioning hole 11, and the remaining connecting bolts 21 on the cross plate 2 are also aligned with the positioning holes 11 near the center positioning hole 11 and are penetrated, and the positioning nut 23 is used for fixing. The tool is moved to the installation site, the center line is aligned, the elevation is marked, the leveling and calibration are performed according to the horizontal bubble 6 on the auxiliary positioning plate 1, the embedded bolt is welded to the reinforcing steel bar according to the situation, or the whole device is fixed by using the support mechanism 7, the device is removed after the concrete is poured and solidified, and the installation and construction of the embedded bolt are realized.

[0041] The device only needs a set of positioning auxiliary plates to install various embedded bolt intervals, and can be suitable for various types of embedded bolts through the bolt clamp 5. The device only needs to determine the type and interval of the embedded bolt, align through the positioning hole 11, and then use the electric tool to install the positioning nut 23 to achieve the effect that the connecting bolt 21 is accurately positioned and not easily disturbed. When installed on site, it can also be quickly disassembled and adjusted according to the actual situation. After determining the center elevation during installation, it only needs to be fine-tuned according to the horizontal bubble 6. In the face of special circumstances, the supporting mechanism 7 can also be used for fixation. The device only needs one person to weld and one person to calibrate to complete the installation.
