Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to an I-beam and H-beam fixing structure. Background Art

[0002] I-beams and H-beams are widely used as supporting frames during steel structure construction. In particular, there are certain problems and limitations in the construction of steel structure frames, such as the lack of timely follow-up of edge protection, the lack of hanging points for safety belts during high-altitude operations, and the lack of hanging points for horizontal nets. Therefore, continuous research and optimization of various protective measures and fixed points taken during steel structure construction should be an important consideration as safety control measures.

[0003] The traditional temporary fixation of the scaffolding uprights on the I-beam is usually fixed by bolt connection devices without damaging the I-beam. When the base plate is fixed to the I-beam wing by bolt connection, auxiliary tools such as wrenches are often required. It is often inconvenient to wear auxiliary tools when moving during the operation. In order to solve the problem of cumbersome movement and inconvenient disassembly during the installation process, the utility model designs a new type of I-beam and H-beam fixing structure, which can be installed, dismantled and moved anytime and anywhere.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0018] like Figure 1 , 2 As shown in 3, the I-beam and H-beam fixing structure of the utility model includes an upper and lower clip structure that are assembled and used in conjunction with each other.

[0019] Among them, Figure 3 , 4 As shown in , 5, the lower buckle structure includes a lower steel plate 9, one end of the lower steel plate 9 is welded and fixed with a vertically opened mounting groove, a first steel tooth structure 10 is arranged on the inner wall of the mounting groove, and the upper buckle structure can be detachably installed in the mounting groove.

[0020] like Figure 2 , 4 As shown in Figure 5, the upper buckle structure includes a finger buckle 2, which is a cavity structure with an opening at the top. A second steel tooth structure 8 is provided on the outer wall of the finger buckle 2 near the lower position. An annular upper steel plate 4 is provided at the middle position of the finger buckle 2, and one section of the upper steel plate 4 extends into the interior of the finger buckle 2, and the other section is located outside the finger buckle 2. The upper steel plate 4 divides the internal space of the finger buckle 2 into upper and lower parts. A connecting rod is installed inside the finger buckle 2, and a connecting block is fixed on the top of the connecting rod as a button 1. A spring 3 is installed on the upper part of the connecting rod, and the spring 3 is located in the upper half of the space inside the finger buckle 2; the inner circle size of the upper steel plate 4 matches the outer diameter size of the connecting rod to ensure that the connecting rod can pass through the upper steel plate 4 but the spring 3 cannot. In the process of pressing the connecting rod by the button 1, the spring 3 will be compressed.

[0021] like Figure 2 , 4As shown in Figure 5, an inverted T-shaped structure is fixed at the bottom of the connecting rod. Since the upper part of the inverted T-shaped structure is smaller than the lower part, the upper part can be used as a steel ball to escape from the slot 5. A steel ball receiving slot 7 is provided on the inner wall of the finger buckle 2 corresponding to the lower part of the inverted T-shaped structure when the spring 3 is not compressed, and the position of the steel ball receiving slot 7 corresponds to the position of the second steel tooth structure 8. A steel ball 6 is installed in the steel ball receiving slot 7.

[0022] Reference Figure 1 , 4 5. In actual use, the lower buckle structure is placed at the connection between the I-beam 11 and the H-beam to ensure that the lower steel plate 9 is in close contact with the lower surface of the upper flange of the I-beam 11, and then the button 1 of the upper buckle structure is pressed to drive the connecting rod and the inverted T-shaped structure to descend as a whole, and the spring 3 is compressed, so that the steel ball detachment slot 5 and the steel ball receiving slot 7 are on the same plane. After the steel ball 6 has sufficient activity space, it rolls from the steel ball receiving slot 7 to the steel ball detachment slot 5, and then the upper buckle structure is placed as a whole into the installation slot of the lower buckle structure; in the current state, the steel ball 6 has no squeezing effect on the second steel tooth structure 8, and there is no contact between the outer wall of the upper buckle structure and the inner wall of the lower buckle structure;

[0023] Next, the pressing operation on the button 1 is canceled. Under the action of the elastic force of the spring 3, the connecting rod and the inverted T-shaped structure move upward as a whole until they return to their original position. During this process, the steel ball 6 gradually falls back into the steel ball receiving groove 7, tightly combined with and squeezed by the second steel tooth structure 8, so that the second steel tooth structure 8 is meshed and fixed with the first steel tooth structure 10, thereby achieving a tight combination and fixation between the upper snap-fit ​​structure and the lower snap-fit ​​structure, and realizing the fixation of the I-beam 11 and the H-beam from one side.

[0024] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
