Prefabricated concrete structures are being rapidly popularized and applied due to their advantages such as energy conservation, environmental protection, and less affected by the construction environment. Steel structure beam-column structures can effectively bear external loads such as gravity, earthquake, and wind load in building structural components. Especially under strong earthquake action, plastic deformation can occur at the beam ends and column ends, effectively absorbing and dissipating energy.

[0003] In the prior art, the connection method of steel structure beam-columns usually adopts welding. A large amount of welding work not only causes high labor intensity for construction workers, but also when the welded and fixed beam-columns need to be disassembled, only equipment such as a cutting machine can be used for destructive disassembly, which is not conducive to the reuse of beam-columns, thus resulting in waste of resources.

Specific embodiments

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. The following will introduce each embodiment of the present utility model in detail with reference to the drawings.

[0021] Please refer to Figures 1 to 5 , the present utility model preferably provides a technical solution: a prefabricated beam-column structure for building engineering construction, including a steel column 1, and a mounting seat 2 fixedly sleeved on the steel column 1. An installation groove 21 is opened at the intersection between the side wall and the upper surface of the mounting seat 2, and an insertion groove 22 is opened at the inner bottom wall of the installation groove 21; a cross beam 3, one end of the cross beam 3 is arranged in the installation groove 21, and an insertion block 4 fixedly connected with the insertion groove 22 in an insertion fit is arranged at the bottom of the cross beam 3. The cross section of the insertion block 4 and the cross section of the insertion groove 22 are both in the shape of a dovetail; it further includes a fixing plate 5, the fixing plate 5 is arranged in the installation groove 21 and is slidably connected with the inner wall of the installation groove 21, and a lifting assembly 6 for driving the fixing plate 5 to lift is installed on the mounting seat 2.

[0022] In this embodiment, by placing one end of the cross beam 3 in the installation groove 21, the insertion block 4 is inserted downward into the insertion groove 22. Since the cross-sections of the insertion block 4 and the insertion groove 22 are both dovetail-shaped, it restricts the horizontal movement of the insertion block 4 and the cross beam 3, avoiding the situation where the insertion block 4 and the cross beam 3 disengage from the installation groove 21 in the horizontal direction. Then, the lifting assembly 6 drives the fixed plate 5 to lift and lower, so that the fixed plate 5 moves downward and abuts against the upper surface of the cross beam 3, thereby playing a role in limiting and fixing the cross beam 3 in the vertical direction. In this way, the cross beam 3 is installed on the steel column 1. When it is necessary to disassemble the cross beam 3, only need to drive the fixed plate 5 to move upward through the lifting assembly 6 and separate from the contact with the cross beam 3, so as to lift the cross beam 3 upward and take it out of the installation groove 21, eliminating the cumbersome operation of connecting by welding, facilitating the quick installation or disassembly of the cross beam 3, improving the installation and disassembly efficiency of the cross beam 3, and being beneficial to the reuse of the beam-column;

[0023] Further, a sliding groove 23 is formed in the inner wall of the installation groove 21; the lifting assembly 6 includes a sliding block 61, the sliding block 61 is fixed to the side wall of the fixed plate 5 and is slidably connected to the inner wall of the sliding groove 23; it also includes a threaded rod 62 that penetrates through the installation seat 2 and is rotatably connected, the threaded rod 62 penetrates through the sliding block 61 and is threadedly connected, and the lower end of the threaded rod 62 is rotatably connected to the inner bottom wall of the sliding groove 23; it also includes a star-shaped handle 63 fixed to the upper end of the threaded rod 62 and a guide rod 64 that penetrates through the sliding block 61 and is slidably connected, the upper end of the guide rod 64 is fixed to the inner top wall of the sliding groove 23, and the lower end of the guide rod 64 is fixed to the inner bottom wall of the sliding groove 23.

[0024] Combined with Figure 3 As shown, when it is necessary to lift and lower the fixed plate 5, the staff only needs to rotate the threaded rod 62 through the star-shaped handle 63. Since the threaded rod 62 is threadedly connected to the sliding block 61, and the sliding block 61 is slidably connected to the inner wall of the sliding groove 23 and the guide rod 64, the sliding block 61 moves along the axial direction of the threaded rod 62, so that the sliding block 61 drives the fixed plate 5 to lift and lower, facilitating the limitation of the cross beam 3.

[0025] Further, a limiting assembly 7 for limiting the threaded rod 62 is installed on the threaded rod 62; the limiting assembly 7 includes a limiting nut 71, and the limiting nut 71 is sleeved on the threaded rod 62 and is threadedly connected to the threaded rod 62.

[0026] As Figure 4 shown, after the fixed plate 5 is driven by the lifting assembly 6 to abut against the cross beam 3, the staff needs to tighten the limiting nut 71 so that the limiting nut 71 abuts against the upper surface of the installation seat 2, thereby restricting the rotation of the threaded rod 62 and reducing the probability that the threaded rod 62 rotates under the action of external force and causes the fixed plate 5 to move.

[0027] Further, the limiting component 7 further includes an annular rubber sheet 72. The annular rubber sheet 72 is sleeved on the threaded rod 62 and is located between the limiting nut 71 and the mounting seat 2. As Figure 4 shown, the annular rubber sheet 72 is made of rubber material, and its surface has a large friction coefficient. The limiting nut 71 cooperates with the upper surface of the mounting seat 2 and presses against the annular rubber sheet 72, increasing the friction force between the limiting nut 71 and the mounting seat 2 and enhancing the limiting effect of the limiting nut 71 on the threaded rod 62.

[0028] Further, a limiting block 8 is fixed to the bottom of the fixing plate 5, and a limiting groove 31 for inserting and cooperating with the limiting block 8 is formed on the upper surface of the cross beam 3. As Figure 2 shown, after the lifting component 6 drives the fixing plate 5 to move downward and press against the upper surface of the cross beam 3, the limiting block 8 is inserted into the limiting groove 31 at the same time, which plays a further fixing role for the cross beam 3 and enhances the stability of the fixing of the cross beam 3.

[0029] Further, a rubber pad 9 is fixed to the bottom of the fixing plate 5. As Figure 2 、 3 shown, the rubber pad 9 is made of rubber material, and its material is elastic. The fixing plate 5 presses against the upper surface of the cross beam 3 through the rubber pad 9, reducing the wear between the fixing plate 5 and the cross beam 3.

[0030] Further, an inclined support rod 10 is fixed to the side wall of the steel column 1, and the upper end of the inclined support rod 10 is fixed to the bottom of the mounting seat 2. As Figures 1 to 3 shown, the inclined support rod 10 plays a role in strengthening and supporting the mounting seat 2, enhancing the stability of the mounting seat 2 and the cross beam 3.

[0031] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated. There are various ways of detachable installation. For example, it can be by the way of inserting and cooperating with a buckle, or by the way of bolt connection, etc.

[0032] The above embodiments are specific descriptions of the present utility model, which are only used to further illustrate the present utility model and cannot be understood as limiting the protection scope of the present utility model. Those skilled in the art make some non-essential improvements and adjustments to the present utility model according to the content of the above utility model, which all fall within the protection scope of the present utility model.
