Description

Technical Field

[0001] The utility model relates to the technical field of the connection between a scaffolding and an I-beam, and specifically relates to a connection device between a cantilever scaffolding and an I-beam. Background Technique

[0002] The cantilever scaffolding is a temporary support system commonly used in high-rise building construction. It transfers the load to the building main body through a cantilever bearing structure (such as an I-beam), avoiding erection from the ground and adapting to complex construction environments. Due to its excellent bending resistance and economy, the I-beam has become the main support member of the cantilever scaffolding.

[0003] Currently, the recognized connection method for the cantilever scaffolding is to directly place the steel pipe on the I-beam, with the steel pipe placed at the end of the I-beam. This method has risks such as the offset of the scaffold, affecting the safety of the project construction. Content of the Utility Model

[0004] The utility model provides a connection device between a cantilever scaffolding and an I-beam. After inserting the I-beam body into the first fixing steel plate, the I-beam body can be fixed to the first fixing steel plate by using the second fixing steel plate, nuts, and bolts, which can increase the safety of the scaffold and the structure is convenient for installation.

[0005] The present utility model is implemented as follows:

[0006] A connection device between a cantilever scaffolding and an I-beam includes a scaffold steel pipe. A first fixing steel plate is fixedly connected to the lower surface of the scaffold steel pipe. A gasket is fixedly connected to the upper surface of the first fixing steel plate. Inside the first fixing steel plate is provided an I-beam body. A second fixing steel plate is provided on the lower surface of the I-beam body. A bolt is threadedly connected inside the gasket. A nut is threadedly connected to the outer surface of the bolt. The bolt penetrates through the second fixing steel plate to the upper surface of the scaffold steel pipe.

[0007] The sleeve connection assembly includes a connection sleeve and a sleeve connection steel bar; the connection between the scaffold steel pipe and the first fixing steel plate is a welding, and two bolts are provided.

[0008] The thickness of the first fixing steel plate is 1 cm, and two nuts are provided.

[0009] The shape of the I-beam body is "I" shaped, and the nut is located on the left side of the first fixing steel plate and the bolt is located on the left side of the first fixing steel plate.

[0010] Compared with the prior art, the present utility model has the following beneficial effects:

[0011] 1. By setting up structures such as the first fixed steel plate, nuts, and the I-beam body, using nuts and bolts to fix the I-beam body can increase the stability of the cantilever scaffold, enhance the safety of the scaffold structure, and the structure is convenient for installation.

Inside the first fixed steel plate 2 is provided an I-beam body 3. The lower surface of the I-beam body 3 is provided with a second fixed steel plate 6. The gasket 7 is internally thread-connected with a bolt 5, and the outer surface of the bolt 5 is thread-connected with a nut 4. The bolt 5 passes through the second fixed steel plate 6 to the upper surface of the scaffold steel pipe 1.

[0019] Please refer to Atta Figure 1 , the connection between the scaffold steel pipe 1 and the first fixed steel plate 2 is welded, and two bolts 5 are provided.
