The bottom of the block is flush with the surface of the lower block and remains stable. The bottom of the first-layer block can be kept stable with a support, and then the clamp assembly of the positioning device is used to fix the upper two sides of the dry-hanging block, and the distance between the block surface and the control line is measured with a ruler. Then, the position of the upper surface of the block is accurately adjusted by rotating the bearing screw in the rolling bearing assembly, so as to achieve the purpose of quickly and accurately adjusting and fixing the upper part of the block, and then carry out subsequent work such as fixing the cantilevers, applying structural adhesive, and removing the positioning device.

[0034] Furthermore, a butterfly handle 12 is provided on one end of the tightening screw 11 located outside the U-shaped iron piece, so that the worker can firmly fix the block material without the aid of a wrench, thereby improving the installation efficiency. At the same time, the rotating handle 9 and the butterfly handle 12 do not interfere with each other up and down.

[0035] The specific implementation process of this utility model:

[0036] Firstly, according to the construction quantity of wall block dry hanging, manpower investment plan, etc., a corresponding number of the utility model block dry hanging precise adjustment and positioning devices are manufactured. The overall length of the device should match the distance from the dry hanging block to the secondary keel; the maximum accommodating thickness of the U-shaped iron piece in the clamp assembly should be about 10mm greater than the block. For example, if the block thickness is 30mm, the net width inside the U-shaped iron piece should not be less than 40mm. All types of U-shaped iron pieces are available in the market. Steel cantilevers can be made of block dry hanging cantilevers; the outer diameter of the bearing screw in the rolling bearing can be selected in the range of 12mm to 16mm, and finished products are also available in the market.

[0037] The specific steps are as follows:

[0038] Before the dry hanging construction of each part, preparations such as the installation of primary and secondary keels and the projection of infrared control lines should be done. This device is installed on both sides of the upper part of the block to be installed, preferably close to the upper part of the vertical plate seam of the block and does not affect the installation of permanent cantilevers. Two devices are preferably set for each block. Bolt holes need to be set on the secondary keels of the angle steel in advance to facilitate the subsequent installation of dry hanging bolts.

[0039] The bottom brackets and structural adhesive of each block should be completed before the block is placed. After the block is placed, the horizontal and vertical positions of the bottom should be adjusted first. The first layer can be supported, and the middle layer blocks are supported by the lower layer blocks and brackets and connected with them flush;

[0040] Then install the positioning device on both sides of the upper part of the block to be installed, use the dry hanging bolts to connect and do not tighten temporarily, then use the device to clamp the block and twist the butterfly handle to tighten the screw to fix the block firmly;

[0041] Use a ruler to measure the distance between the block surface and the infrared control line, use the long first bolt hole on the steel cantilever to roughly adjust the vertical flatness of the block and tighten the dry hanging bolts;

[0042] Use a ruler to measure the distance between the block surface and the infrared control line again, and use the rotating handle to twist the bearing screw to adjust the vertical flatness of the block surface until the block position is accurately located and stop;

[0043] Then start installing the permanent brackets on the upper part of the block, applying structural adhesive and other follow-up work. After the structural adhesive has a certain strength, the device can be removed and the next block can be installed. Before dismantling the device, the clamp should be released first, and then the dry hanging bolts should be removed.
