[0019] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments only are a part of embodiments of the utility model, and not all embodiments.

[0020] The steel structure has a main plate 1 and a vice plate 2 for clamping.

[0021] As shown in the drawings, Figs. 1-3 The four corners of the main plate 1 and the vice plate 2 are provided with inclined holes 11, the side of the main plate 1 away from the vice plate 2 is provided with an adjusting plate 3, the four corners of the adjusting plate 3 are provided with a waist-shaped hole 31, the inclined holes 11 of the corresponding corners of the main plate 1 and the vice plate 2 are penetrated by clamping bolts 4, one end of the clamping bolt 4 penetrates the corresponding waist-shaped hole 31 of the adjusting plate 3, the clamping bolt 4 is in sliding connection with the waist-shaped hole 31 and the inclined hole 11, and the outer side of the end of the clamping bolt 4 extending out of the waist-shaped hole 31 is threadedly connected with a nut 5.

[0022] When the steel structure parts need to be clamped, the clamping bolt 4 penetrates the inclined holes 11 of the main plate 1 and the vice plate 2 and continues to penetrate the waist-shaped hole 31 of the adjusting plate 3, wherein by rotating the position of the adjusting plate 3 relative to the main plate 1, the clamping bolt 4 can be guided to slide in the inclined hole 11 due to the change of the angle of the waist-shaped hole 31, so that the four clamping bolts 4 are close to or separated from each other relative to the center point of the main plate 1 and the vice plate 2, in this way, the main plate 1 and the vice plate 2 can be clamped to each other by adjusting the clamping bolt 4, forming a cross combined steel structure part, and the clamping bolt 4 can be self-adaptively close to and clamp each clamping angle of the cross steel structure combined part of different sizes.

[0023] In order to ensure the stability of clamping, by rotating the nut 5, it can be tightly pressed on the adjusting plate 3, so as to generate enough clamping force to firmly clamp the steel structure parts together.

[0024] As shown in the drawings, Figs. 1-3 The outer side of the part of the clamping bolt 4 penetrating the inclined holes 11 of the main plate 1 and the vice plate 2 and the waist-shaped hole 31 of the adjusting plate 3 is sleeved with a gasket 6, the gasket 6 increases the contact area between the clamping bolt 4 and the vice plate 2 and the adjusting plate 3, thereby enhancing the clamping effect and preventing loosening caused by long-term stress or vibration.

[0025] As shown in the drawings, Figs. 1-3 The center of the side of the main plate 1 away from the vice plate 2 is fixedly connected with a short rod 7, the center of the adjusting plate 3 is slidingly and rotatably connected to the outer side of the short rod 7, the short rod 7 serves as a supporting and guiding part, ensuring the stable movement and rotation of the adjusting plate 3 on the main plate 1.
