[0002] Scaffolding is a working platform or temporary structure erected to ensure the smooth progress of various construction processes. Scaffolding can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to its material. Among them, steel pipe scaffolding is widely used because of its high strength and good stability. The steel pipes are usually hollow to reduce weight and facilitate handling and installation.
[0003] However, when assembling and installing common steel pipe scaffolding, the horizontal bars are usually fixed to the vertical main steel pipes by welding. This connection method is not convenient for subsequent recycling. Since the scaffolding needs to be dismantled by cutting, the cut horizontal bars are difficult to reuse, reducing the recycling rate. Furthermore, both the initial welding and the later cutting and dismantling are troublesome, extending the construction period.
[0004] Therefore, it is necessary to provide a new type of scaffolding steel pipe crossbar connection assembly to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the novel scaffolding steel pipe crossbar connecting assembly provided by this utility model; Figure 2 This is an assembly diagram of the vertical main steel pipe and the U-shaped external frame in this utility model; Figure 3 This is a schematic diagram of the opening structure of the U-shaped groove and the limiting sink groove in this utility model; Figure 4 This is an assembly diagram of the transverse solid steel pipe and the transverse hollow steel pipe in this utility model; Figure 5This is a schematic diagram showing the disassembled horizontal solid steel pipe and horizontal hollow steel pipe of this utility model. The novel scaffolding steel pipe horizontal bar connecting assembly includes: two vertical main steel pipes 1. These two vertical main steel pipes 1 are only a part of the scaffolding components. In the actual erection of the scaffolding, there will be multiple identical components. Here, only one representative component is described. Multiple connecting seats 6 are fixedly installed on each of the two vertical main steel pipes 1. The top of each of the multiple connecting seats 6 is provided with a U-shaped groove 7, and the side of each pair of corresponding U-shaped grooves 7 that are close to each other is open. The top of each of the multiple connecting seats 6 is provided with a limiting groove 8, and the multiple limiting grooves 8 are respectively connected to the multiple U-shaped grooves 7. Multiple horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 are provided between the two vertical main steel pipes 1. The ends of the corresponding horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 are in contact with each other, and the ends of the corresponding horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 that are far apart from each other extend into the corresponding U-shaped grooves 7. Limiting blocks 9 are fixedly installed at the ends of the vertical main steel pipe 1 and the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3, which are far apart from each other. Multiple limiting blocks 9 are located in multiple limiting grooves 8, which enables the assembly and connection of the vertical main steel pipe 1, the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3. Extension steel pipes 4 are slidably installed in multiple horizontal hollow steel pipes 3. The ends of multiple extension steel pipes 4 are fixedly connected to one end of multiple horizontal solid steel pipes 2. Through the extension of the extension steel pipes 4, the total length of the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3 can be adjusted, so as to be suitable for connection work in various situations. In addition, locking screws 5 are threaded on multiple horizontal hollow steel pipes 3. The bottom ends of multiple locking screws 5 abut against multiple extension steel pipes 4. After adjusting the total length of the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3, the locking screws 5 can be used to lock them, which facilitates subsequent connection operations.
[0022] In the above method, in order to position the transverse solid steel pipe 2 and transverse hollow steel pipe 3, positioning through holes 10 are provided on multiple transverse solid steel pipes 2 and transverse hollow steel pipes 3. Positioning posts 15 are slidably installed on one side of multiple connecting seats 6. One end of multiple positioning posts 15 extends into multiple positioning through holes 10. Furthermore, C-shaped external brackets 11 are fixedly installed on two vertical main steel pipes 1. Pushing screws 12 are threaded on one side of two C-shaped external brackets 11. Connecting pieces 13 are rotatably installed on two pushing screws 12. Multiple transverse connecting arms 14 are fixedly installed on the side of the two connecting pieces 13 that are close to each other. Multiple positioning posts 15 are fixedly connected to multiple transverse connecting arms 14. By rotating the pushing screws 12 clockwise or counterclockwise, the positioning posts 15 can be brought out or brought into the positioning through holes 10, thereby achieving a fixing effect on the transverse solid steel pipe 2 and transverse hollow steel pipe 3.
[0023] In this method, in order to ensure that the connecting piece 13 can only move in a straight line, two limiting rods 16 are fixedly installed on the inner wall of one side of each of the two C-shaped outer frames 11. The two corresponding limiting rods 16 pass through the corresponding connecting piece 13 and slide to connect with the corresponding connecting piece 13, thereby achieving the limiting effect.
[0024] In this method, in order to allow the positioning pin 15 to be smoothly inserted into the positioning through hole 10, a through hole is provided on one side of each of the two connecting seats 6. The multiple through holes are connected to multiple U-shaped grooves 7 respectively, and the multiple positioning pins 15 pass through multiple through holes and contact the inner wall of the corresponding through hole.
[0025] The working principle of the novel scaffolding steel pipe crossbar connecting assembly provided by this utility model is as follows:
[0026] When multiple horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 need to be connected, first place two vertical main steel pipes 1 in the designated position, then take out a set of horizontal solid steel pipes 2 and horizontal hollow steel pipes 3, insert the horizontal solid steel pipe 2 into the U-shaped groove 7 on one of the connecting seats 6, and insert the limiting support block 9 on it into the corresponding limiting groove 8, then tighten the corresponding locking screw 5 to separate it from the extension steel pipe 4, then pull the horizontal hollow steel pipe 3 into the U-shaped groove 7 on another corresponding connecting seat 6, and insert the limiting support block 9 on it into the corresponding limiting groove 8, then tighten the locking screw 5;
[0027] Then, in the same manner as above, insert the remaining horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 into the corresponding U-shaped grooves 7 from bottom to top. After all the insertions are completed, rotate the push screws 12 on the two C-shaped external brackets 11 clockwise. The two push screws 12 move in the direction of their respective vertical main steel pipes 1, so that the multiple positioning pins 15 are gradually inserted into the corresponding positioning through holes 10 until they are fully inserted. At this point, the installation of the horizontal solid steel pipes 2 and horizontal hollow steel pipes 3 is completed.
[0028] During the subsequent disassembly process, simply rotate the multiple push screws 12 counterclockwise to bring out the multiple positioning pins 15 from the corresponding positioning through holes 10, and the transverse solid steel pipe 2 and transverse hollow steel pipe 3 can be directly removed for reuse next time.
[0029] Compared with related technologies, the novel scaffolding steel pipe crossbar connection assembly provided by this utility model has the following beneficial effects:
[0030] This utility model provides a novel scaffolding steel pipe horizontal bar connection assembly. By opening a U-shaped groove 7 on the connecting seat 6, the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3 can be directly inserted into the corresponding U-shaped groove 7. Then, the positioning effect of the positioning column 15 and the positioning through hole 10 is used to connect the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3, thereby speeding up the erection of scaffolding. Furthermore, during subsequent dismantling, simply rotating the push screw 12 will bring the positioning column 15 out of the positioning through hole 10, and the dismantling process can be completed quickly, reducing the construction cycle. In addition, the extension steel pipe 4 allows the total length of the horizontal solid steel pipe 2 and the horizontal hollow steel pipe 3 to be adjusted, thereby allowing for adjustment based on the actual distance between the two vertical main steel pipes 1, providing high flexibility.
