Description

Technical Field

[0001] The technical solution belongs to the field of construction engineering, and specifically is a structural layer paving hanging device. Background Art

[0002] At present, the hanging lines for paving the structural layer at the construction site are threaded steel bars with tripod-supported steel strands.

[0003] However, in the process of implementing the embodiments of the present application, the inventors discovered that the prior art uses a triangular bracket in conjunction with threaded steel to control elevation. In principle, this utilizes the friction between the tripod screws and the threaded steel when tightened, as well as the supporting effect of the threads, to stabilize the tripod. In actual operation, firstly, due to the gaps between the threads of the threaded steel, the bolts are prone to slippage and dislocation when tightened. Secondly, the tripod bracket is prone to rotating in the direction of the threads when the bolts are tightened. Thirdly, the wire rope is tied to the triangular bracket with wire. If the tie is tight, the wire rope is likely to drag the triangular bracket, causing it to rotate and dislocate. If the tie is loose, the wire rope is likely to fall off and slide.

[0004] Therefore, the existing operation method has the technical problem of low efficiency in adjusting the wire rope mark and the threaded steel thread easily causing misalignment when the bolt is tightened. Summary of the Invention

[0005] The purpose of the present invention is to provide a structural layer paving wire hanging device, which improves the structure of the expansion joint of the bridge deck sidewalk so that after the expansion joint is installed, it has a long service life, low maintenance costs, and good sealing effect, and eliminates the occurrence of water leakage at the expansion joint position. The specific scheme is as follows:

[0006] A structural layer paving wire hanging device, comprising:

[0007] Bracket: The bracket is provided with a U-shaped limiting groove;

[0008] Limiting device: The limiting device is a limiting rod, which can pass through one end of the bracket so that the limiting rod can move forward and backward in the U-shaped limiting groove;

[0009] Lifting mechanism: The lifting mechanism is arranged at the bottom of the bracket and is used to adjust the height of the bracket.

[0010] Furthermore, the lifting mechanism includes an adjusting cylinder, a positioning rod, and an adjusting mechanism for adjusting the distance of the positioning part in the adjusting cylinder. The adjusting cylinder is fixedly connected below the bracket, and the positioning rod is used to fix the lifting mechanism at a specific point.

[0011] Furthermore, the limiting rod is provided with a thread, and the limiting rod is threadedly connected to one end of the bracket so that the limiting rod can rotate on one end of the bracket through the thread.

[0012] Furthermore, the positioning rod is provided with a thread, and a nut is threadedly connected to the positioning rod as an adjustment mechanism. The adjustment cylinder is sleeved on the positioning rod, and the inner diameter of the adjustment cylinder is smaller than the outer diameter of the nut, so that the height of the bracket can be adjusted by adjusting the position of the nut on the positioning rod.

[0013] Furthermore, as another option, the adjustment mechanism includes: a quick-release device, which is installed at the bottom of the adjustment cylinder so that it can adjust the distance of the positioning rod in the adjustment cylinder through quick release. The quick-release device is made of quick-release fastening and is commonly used for height adjustment of bicycle seats. It is a common fastening adjustment structure, and this application does not make other improvements to the structure of the quick-release device, so it will not be repeated here.

[0014] Furthermore, the gap between the limiting rod and the bottom surface of the U-shaped limiting groove is greater than or equal to the maximum width of the wire rope.

[0015] Furthermore, the gap between the limiting rod and the bottom surface of the U-shaped limiting groove is equal to the maximum width of the wire rope.

[0016] Furthermore, the limiting rod includes: a clamping part and a connecting part, the connecting part is provided with a thread for threaded connection with one end of the bracket, so that the limiting rod can rotate in the U-shaped limiting groove; the clamping part is an arc-shaped long strip protrusion, so that the arc-shaped long strip protrusion can be moved closer to or away from the bottom surface of the U-shaped limiting groove by rotating the limiting rod to adjust the gap between the limiting rod and the bottom surface of the U-shaped limiting groove.

[0017] Furthermore, the bottom of the positioning rod is conical as a positioning portion, so that the positioning rod can be inserted into the soil.

[0018] Compared with the prior art, the structure layer paving hanging device of the utility model has the following beneficial effects:

[0019] The present application provides a structural layer paving hanging device, which eliminates the need to use steel wire to tie steel strands by replacing the triangular bracket with a square bracket with grooves to prevent them from falling off or being pulled.

[0020] This application tool is easy to maintain, saving later costs, and no wrench is required when adjusting the elevation, which can be adjusted manually directly, improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
