Problems solved by technology
The truss structure generally adopts H-shaped steel structure. How to quickly realize the aerial docking and positioning of the H-shaped steel structure is the key to solving the problem. The current positioning and docking devices generally have the following problems: 1) The structure is heavy and complicated, which is not conducive to carrying; 2) It does not have Fixed effect, cannot prevent deviation caused by movement; 3) Cannot be used in the air, or can only be used in vertical docking

The invention relates to an adjustable portable H-shaped steel structural aerial butting positioning clamp. The adjustable portable H-shaped steel structural aerial butting positioning clamp is characterized by comprising a flange plate positioning block, two flange plate clamping blocks, two web plate positioning clamping blocks and four groups of screw nut assemblies, wherein the flange plate positioning block is provided with two screw holes; a kidney-shaped hole is formed in each of the horizontal direction and the vertical direction of each flange plate clamping block; the two screw holes in the flange plate positioning block are respectively opposite to the kidney-shaped holes in the horizontal direction of the two flange plate clamping blocks; two groups of the screw nut assemblies respectively penetrate through two groups of corresponding screw holes and kidney-shaped holes to connect the flange plate positioning block to the two flange plate clamping blocks; the other two groups of the screw nut assemblies respectively penetrate through the kidney-shaped holes in the vertical direction of the two flange plate clamping blocks to form a straight line, and a wed plate positioning clamping block is fixed to each of the two ends, point to each other, of the two groups of the screw nut assemblies. The adjustable portable H-shaped steel structural aerial butting positioning clamp is simple in structure, convenient to detach, wide in applicability and accurate in positioning, and has a fixing effect.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to an adjustable and portable H-shaped steel structure aerial docking positioning fixture. [0002] technical background [0003] It is more and more common to use truss structures in steel structure workshops. When truss structures are installed on site, the installation of large-span trusses often requires segmental hoisting after overall assembly. Due to the difficulty of docking in the air during hoisting, the docking positioning takes a long time. The shift cost is relatively high. If the problem of aerial docking and positioning can be solved quickly and effectively, the installation efficiency can be greatly improved, the shift of lifting machinery can be saved, and the cost can be reduced. The truss structure generally adopts H-shaped steel structure. How to quickly realize the aerial docking and positioning of the H-shaped steel structure is the key to solvin...
