Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a gourd-shaped steel pipe joint clamp. Background Art

[0002] Scaffolding construction, as a common auxiliary operation in on-site construction, is widely used in various construction occasions, including high-altitude operations, deep foundation pit operations, bridges, building construction, open-cut structures, etc., and has a wide range of applications.

[0003] In the process of steel pipe scaffolding and support operation, there is a common situation that the corresponding tool-type accessories are often lacking, causing many inconveniences in the on-site scaffolding and support construction. Such situations are T-joint and cross-joint situations. For these on-site construction, longer steel pipes are usually used, using cross clamps or universal clamps to form a superimposed and crossed structure.

[0004] There are certain disadvantages of overlapping and intersecting structures. They are as follows:

[0005] 1. The overlapping intersection has the disadvantage of poor cross bar strength resistance. The vertical downward force is the shear force of the buckle node, and the tolerance is small.

[0006] 2. Compared with butt joint, overlapping and crossing wastes pipe materials. It will increase the overall material consumption, which is quite significant for the whole project.

[0007] 3. The outward extension of the pipe head reduces the aesthetics, and is not suitable for construction sites that have high requirements on appearance, such as guardrails.

[0008] 4. Excessive horizontal steel pipes increase the risk of the frame being scratched and people being injured by the frame. Utility Model Content

A first top plate 200 is provided in the first side tube 110, and the first top plate 200 can rotate or slide up and down in the first side tube 110. The first top pin 300 is provided in the first side tube 110 and is threadedly connected to the first side tube 110, and the end of the first top pin 300 that penetrates into the inner cavity of the main card body 100 is rotatably connected to the first top plate 200. By rotating the first top pin 300, the first top plate 200 can be driven to be pressed against the steel pipe inserted into the main card body 100.

[0043] When in use, first insert one end of the two steel pipes to be connected into the main card body 100 from both ends of the main card body 100, or pass the steel pipe through the entire main card body 100, and then rotate the first push pin 300 to drive the first top plate 200 to press on the steel pipe, so that the main card body 100 can be connected and fixed to the steel pipe.

[0044] The use of this gourd-shaped steel pipe joint clamp has the following advantages:

[0045] 1. Since the downward force is the shear force of the buckle node, the tolerance is small, which can solve the disadvantage of poor strength resistance of the cross bar of the overlapped intersection.

[0046] 2. Since there is no need for overlapping and crossing, the problem of wasting pipes compared with butt jointing can be solved.

[0047] 3. It can reduce the length of the pipe head extending outward, thereby improving the aesthetics of construction with high requirements on appearance.

[0048] 4. Since the redundant horizontal steel pipes are reduced, the risk of the frame being scratched and the risk of injury to people can be reduced.

[0049] Preferably, a step 120 is provided on the inner wall of the main card body 100. By means of the step 120, the lower half of the steel pipe can be raised, so as to facilitate the compression of the first top plate 200.
