It is necessary to determine the positions of the connection nodes before leaving the factory, and it is not easy to adjust according to the needs of the building during actual use. Moreover, most of them cannot adapt to building errors. When the errors between the cross beams and longitudinal beams of the building are large, most of them cannot be used, resulting in the problem of low applicability. Content of the Utility Model

[0023] By providing a prefabricated steel structure for buildings in the embodiments of the present application, the problems that the existing prefabricated steel structures are not easy to be adjusted according to the needs of buildings during actual use and have low applicability are effectively solved.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical solutions in the embodiments of the present application effectively solve the technical problems that the existing prefabricated steel structures are not easy to be adjusted according to the needs of buildings during actual use and have low applicability. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the present utility model provides a prefabricated steel structure for buildings, which includes a cross bar 1. Both ends of the cross bar 1 are fixedly connected with assembly plates 2. Four installation holes are opened on the surfaces of the two assembly plates 2. An adjusting rod 3 is slidably connected inside the cross bar 1. Lubricating oil is applied between the adjusting rod 3 and the cross bar 1. An adjusting mechanism 6 is arranged at the top of the adjusting rod 3. A connecting slider 4 is fixedly connected to the side wall of the adjusting rod 3. A vertical rod 401 is fixedly connected to the side of the connecting slider 4 away from the adjusting rod 3. A clamping groove 402 is opened on the side of the vertical rod 401 close to the cross bar 1. The clamping groove 402 is clamped with the cross bar 1. The adjusting mechanism 6 includes a support shaft 601.

[0026] A moving groove 101 is opened on the top surface of the cross bar 1. A passing groove 102 is opened on the side wall of the cross bar 1. The passing groove 102 is slidably connected with the connecting slider 4. A tooth groove 103 is fixedly opened on one side of the moving groove 101.

[0027] Two liquid filling ports 5 are fixedly connected to the top of the adjusting rod 3. Two flow pipes 501 are fixedly connected to both liquid filling ports 5. One ends of the two flow pipes 501 away from the liquid filling ports 5 penetrate through the adjusting rod 3.

[0028] On the inner side of the adjusting rod 3 away from the connecting slider 4, two main flow holes 301 are opened. On the side wall of the adjusting rod 3 away from the connecting slider 4, two groups of secondary flow holes 302 are opened. The number of each group of secondary flow holes 302 is four. The two groups of secondary flow holes 302 are respectively communicated with the two main flow holes 301. The two main flow holes 301 are respectively communicated with the two flow pipes 501. On the top of the side of the adjusting rod 3 close to the connecting slider 4, two secondary flow holes 302 are opened. The two secondary flow holes 302 are respectively communicated with the two flow pipes 501 in the direction close to the connecting slider 4.

[0029] The support shaft 601 is fixedly installed inside the main flow hole 301. The support shaft 601 is rotationally connected with a rotating shaft 602. The top of the rotating shaft 602 is fixedly connected with a runner 604. The upper half of the rotating shaft 602 is fixedly connected with a gear 603.

[0030] The gear 603 is meshed and clamped with the tooth groove 103.

[0031] First, the cross bar 1 is connected to the cross beam through the assembly plates 2 fixedly connected to both ends. When there is an error in the docking of the longitudinal beam and the cross beam, the runner 604 can be rotated. The runner 604 drives the rotating shaft 602 to rotate. The rotating shaft 602 drives the gear 603 to rotate. The gear 603 is meshed and clamped with the tooth groove 103. Therefore, when the runner 604 is rotated, the gear 603 will push the adjusting rod 3 to slide inside the cross bar 1. When the adjusting rod 3 moves, the connecting slider 4 slidably connected through the through groove 102 will also slide, and finally drive the longitudinal rod 401 to move, adjusting the position of the longitudinal rod 401 to dock with the cross beam with installation errors, solving the technical problem that the existing assembled steel structure is not easy to be adjusted according to the needs of the building during actual use and has low applicability.

[0032] Working principle:

[0033] First, the cross bar 1 is connected to the cross beam through the assembly plates 2 fixedly connected to both ends. When there is an error in the docking of the longitudinal beam and the cross beam, the runner 604 can be rotated. The runner 604 drives the rotating shaft 602 to rotate. The rotating shaft 602 drives the gear 603 to rotate. The gear 603 is meshed and clamped with the tooth groove 103. Therefore, when the runner 604 is rotated, the gear 603 will push the adjusting rod 3 to slide inside the cross bar 1. When the adjusting rod 3 moves, the connecting slider 4 slidably connected through the through groove 102 will also slide, and finally drive the longitudinal rod 401 to move, adjusting the position of the longitudinal rod 401 to dock with the cross beam with installation errors. After the cross beam, the longitudinal beam and the device are docked, glue can be poured into the two liquid filling ports 5. The glue flows into the main flow hole 301 through the flow pipe 501, and finally flows into the secondary flow hole 302 through the main flow hole 301, flowing into the gap between the adjusting rod 3 and the cross bar 1 to fix the cross bar 1 and the adjusting rod 3.

[0034] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
