Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a welding point stress detection device for a tree-shaped column panel. Background Art

[0002] At present, tree-shaped columns have been widely used in airports, stations, large public buildings and other fields. The selection and design of its panels should be coordinated with the overall structure of the tree-shaped column to improve the aesthetics and practicality of the building. The commonly used method is to use steel panels for welding. The panel of the tree-shaped column should not only be beautiful during welding, but also take into account factors such as structural stability, bearing capacity and safety. Therefore, it is necessary to test the welding performance of the tree-shaped column panel.

[0003] However, most of the existing steel structure stress detection devices only apply loads to the ribs on the side of the panel to realize stress detection of the welding points between the ribs and the surface. However, the panel will also be subjected to wind force when in use. The existing steel structure stress detection devices cannot apply loads to the panel surface, that is, they cannot detect the stress of the welding points between the horizontal ribs and the vertical ribs on the panel.

[0004] To this end, we propose a stress detection device for welding points of tree-shaped column panels. Summary of the invention

[0010] It is further defined that the horizontal loading assembly includes a mounting base plate, a mounting vertical plate and a horizontal telescopic rod; the mounting vertical plate is vertically arranged on the mounting base plate, the tail of the horizontal telescopic rod is fixed on the mounting vertical plate, the mounting base plate in the direction of the head of the horizontal telescopic rod is connected to the vertical plate of the right clamping block, and the vertical plate of the right clamping block is provided with a through groove for the horizontal telescopic rod to pass through; by fixedly connecting the mounting base plate and the right clamping block, the horizontal telescopic rod and the right clamping block can be driven to move synchronously close to the tree-shaped column panel when clamped, so that the working stroke of the horizontal telescopic rod is shorter, the optional horizontal telescopic rod specifications are lower, and the use cost is saved.

[0011] It is further defined that the first sliding assembly includes a first sliding screw, a head insertion block, a tail insertion block and a first turning handle; the head insertion block and the tail insertion block are respectively fixedly arranged on the left and right sides of the bottom surface of the base plate, the tail of the first sliding screw is rotatably arranged on the tail insertion block through a bearing, and the head passes through the head insertion block, the first turning handle is fixedly arranged on the head end of the first sliding screw, the two sliding blocks are threadedly arranged on the first sliding screw, and the thread directions of the two sliding blocks are opposite, so that the two sliding blocks can slide relative to or opposite to each other at the same time; rotating the first sliding screw through the first turning handle can drive the two sliding blocks to move relative to or opposite to each other, thereby realizing the relative movement and clamping or the opposite movement and loosening of the left clamping block and the right clamping block, which is very convenient, and the sliding screw has a self-locking function and will not rotate automatically.
