[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, a steel structure combining a multi-story steel frame and a portal steel frame comprises a plurality of floors 1, wherein the floors 1 are square in shape and are arranged in a rectangular shape. A plurality of load-bearing columns 2 are arranged on the lower surface of the floor 1, and the load-bearing columns 2 are arranged at the connecting position of adjacent floors 1, that is, two adjacent floors 1 on the four sides share a load-bearing column 2, four floors 1 in the middle share a load-bearing column 2, and the floors 1 at the four corners use a single load-bearing column 2. A plurality of inclined supporting columns 3 are arranged on the surface of the load-bearing column 2, two supporting columns 3 are used for the load-bearing columns 2 at the four sides, and four supporting columns 3 are used for the load-bearing columns 2 at the four corners. The load-bearing columns 2 at the four corners do not need to use supporting columns 3, and the tops of the supporting columns 3 are against the lower surface of the floor 1.

[0020] A larger area of ​​floor 1 is set up, and each floor 1 is supported by four load-bearing columns 2, which can greatly improve the supporting force of the floor 1. At the same time, the connection positions of the four floors 1 share one load-bearing column 2, so the number of load-bearing columns 2 can also be reduced, thereby reducing the cost of use. At the same time, by adding oblique support columns 3, a greater supporting force is provided for the floor 1, preventing the floor 1 itself from undergoing a large deformation during use, thereby increasing the service life.

[0021] The load-bearing column 2 is configured as a rectangular steel tube, and the diagonal position of the load-bearing column 2 coincides with the connecting line position of the floor 1, ensuring that the support force of the load-bearing column 2 on each floor 1 is the same, avoiding uneven force on the load-bearing column 2, thereby affecting the service life of the load-bearing column 2. The four support columns 3 are obliquely arranged on the surface of the load-bearing column 2, and four support columns 3 are arranged under each floor 1. The load-bearing column 2 provides support force for the support column 3 along the oblique direction of the support column 3, and the support column 3 provides a larger support force for the floor 1, thereby avoiding a large deformation of the floor 1 during use and ensuring the overall service life.

[0022] The two support columns 3 are obliquely arranged on the surface of the load-bearing column 2 , and the two support columns 3 are symmetrically installed to ensure that the surrounding floors 1 are supported by the support columns 3 , so that each floor 1 has a greater supporting force.

[0023] The ends of the support column 3 and the load-bearing column 2 are fixedly installed with mounting plates 4, that is, mounting plates 4 are provided at both ends of the support column 3 and both ends of the load-bearing column 2, the mounting plate 4 and the support column 3 are an integrated molding structure, and the load-bearing column 2 and the mounting plate 4 are an integrated molding structure, which improves the connection force between the support column 3 and the load-bearing column 2, and a plurality of mounting holes 5 are opened on the surface of the mounting plate 4, which are fixed and installed through the mounting holes 5 with bolts, and the installation method is simple and convenient, and at the same time has high stability.

[0024] A gravity detection sensor 6 is installed inside the support column 3 to detect the weight of the goods above the floor 1 to avoid excessive pressure on the load-bearing column 2.

[0025] It should be noted that the utility model is a steel structure combining a multi-layer steel frame and a portal steel frame. When in use, the support column 3 is fixed to the surface of the load-bearing column 2 by the cooperation of bolts and mounting holes 5. Two support columns 3 and four support columns 3 are installed correspondingly, and the floor 1 is fixed to the top of the support column 3 and the load-bearing column 2 through the mounting holes 5. Each floor 1 is supported by four load-bearing columns 2, which can greatly improve the supporting force of the floor 1. At the same time, the connection positions of the four floors 1 share one load-bearing column 2, so the number of load-bearing columns 2 can also be reduced, thereby reducing the cost of use. The load-bearing column 2 provides the support column 3 with a supporting force obliquely along the support column 3, and the support column 3 provides a larger supporting force for the floor 1, thereby avoiding large deformation of the floor 1 during use and ensuring the overall service life.
