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

[0002] Scaffolding construction is a common auxiliary operation in field construction and 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

[0016] Furthermore, a limiting block is provided at the top end of the insertion rod, and a size of the limiting block is larger than an outer diameter of the first locking nut.

[0038] See also Figures 1 to 6 The utility model provides a steel pipe T-joint clamp, comprising a vertical clamp 100, a vertical pipe 200 and a lateral clamp 300.

[0039] Specifically, the vertical clamp 100 can be fixed on the steel pipe. The vertical pipe 200 can be slidably mounted on the steel pipe, and the vertical pipe 200 is movably connected to the vertical clamp 100. The lateral clamp 300 includes a lower semicircular side clamp 310 and an upper semicircular side clamp 320. The lower semicircular side clamp 310 is fixedly connected to the vertical pipe 200 to support the steel pipe. The upper semicircular side clamp 320 is detachably connected to the lower semicircular side clamp 310. The upper semicircular side clamp 320 can fix the steel pipe with the lower semicircular side clamp 310.

[0040] When in use, first erect the steel pipe where the frame needs to be erected, then put the connected vertical pipes 200 on the erected steel pipe, and then hold the vertical clamp 100 tightly on the steel pipe, then place one end of the horizontal steel pipe on the lower semicircular side clamp 310, and then connect and fix the upper semicircular side clamp 320 with the lower semicircular side clamp 310, so that one side installation is completed, and then the other side is installed in the same way to complete the T-shaped connection between the two steel pipes.

[0041] The above steel pipe T-joint clamp has the following advantages:

[0042] 1. It can solve the disadvantage of poor crossbar strength in overlapping and crossing structures;

[0043] 2. Solve the problem of wasting pipes in overlapping and crossing compared with butt jointing;

[0044] 3. Solve the problem of reduced aesthetics caused by the outward-facing pipe head;

[0045] 4. Solve the problem that the redundant horizontal steel pipes increase the risk of the frame being scratched and people being injured;

[0046] In this embodiment, the vertical card 100 includes two vertical semicircular cards 110 hinged to each other, and the two vertical semicircular cards 110 can be interlocked with each other to form a circular vertical card 100, and a plug rod 120 is vertically arranged on one of the vertical semicircular cards 110. The side wall of the vertical tube 200 is arranged on the connecting block 210. The connecting block 210 is provided with a plug hole, and the plug rod 120 can be slidably inserted into the plug hole. The plug rod 120 is threadedly connected with a first locking nut 130, and the first locking nut 130 can be abutted and pressed against the connecting block 210 by rotating the first locking nut 130.

[0047] By adopting this method, it is convenient to hold the vertical clamp 100 tightly on the steel pipe, and it is also convenient to fix the vertical clamp 100 and the vertical pipe 200 together.

[0050] In addition, a limit block 140 is disposed at the top of the insertion rod 120, and the size of the limit block 140 is larger than the outer diameter of the first locking nut 130. The limit block 140 can prevent the first locking nut 130 from falling off from the top of the insertion rod 120.

[0051] In this embodiment, one end of the lower semicircular side clamp 310 and the upper semicircular side clamp 320 are hinged to each other, and the other end can be detachably connected through a bolt connection assembly. This method is convenient for fixing the transverse steel pipe.

[0052] In addition, a reinforcing rib 330 is connected to the bottom of the lower semicircular side clamp 310, and the reinforcing rib 330 is connected and supported on the vertical tube 200. The reinforcing rib 330 can improve the supporting effect of the lower semicircular side clamp 310.

[0055] When in use, first erect the steel pipe where the frame needs to be erected, then put the vertical pipe 200 on the vertical steel pipe, and hold the vertical semicircular clamp 110 tightly on the steel pipe, then lock the first locking nut 130, and then place one end of the horizontal steel pipe on the lower semicircular side clamp 310, and then connect and fix the upper semicircular side clamp 320 with the lower semicircular side clamp 310, so that one side installation is completed, and then the same installation method is used to install the other side to complete the T-shaped connection between the two steel pipes.

[0056] The use of upper steel pipe T-joint clamps can not only solve the disadvantage of poor cross bar strength resistance in overlapping and crossing, but also solve the problem of waste of pipes compared with butt jointing, and also solve the problem of reduced aesthetics caused by the outward extension of the pipe head, and at the same time solve the risk of increased scratches and injuries to the frame due to the extension of excess horizontal steel pipes, and the connection of the entire device components is convenient and stable, and the strength is reliable.
