[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. EMBODIMENT

[0029] Please refer to Figures 1-5 As shown in the figure, the embodiment provides a fabricated building steel structure, which comprises an H-shaped steel structure main body 1, the H-shaped steel structure main body 1 is jointly formed by horizontal columns and vertical columns arranged orthogonally to each other, and the H-shaped steel structure main body 1 is sleeved with a supporting and fixing assembly 2 on the surface, wherein the two ends of the supporting and fixing assembly 2 are respectively sleeved and connected with the outer surfaces of the horizontal columns and the vertical columns, and the supporting and fixing assembly 2 provides an inclined supporting action for the H-shaped steel structure main body 1 in an inclined state;

[0030] The supporting and fixing assembly 2 is sleeved and embedded with a supporting and fixing connecting assembly 3, when the supporting and fixing assembly 2 and the supporting and fixing connecting assembly 3 are sleeved and embedded with each other, the supporting and fixing connecting assembly 3 is inclined, and simultaneously supports the H-shaped steel structure main body 1;

[0031] The H-shaped steel structure main body 1 is arranged in parallel and vertically along the direction perpendicular to the ground by two vertical columns, and the two vertical columns are connected in the horizontal direction by the horizontal columns;

[0032] Firstly, the support fixing assembly 2 is sleeved on the surface of the H-shaped steel structure body 1, and the two ends are respectively tightly sleeved and connected with the outer surface of the horizontal column and the outer surface of the vertical column. Then, the support fixing connecting assembly 3 is sleeved and embedded on the surface of the support fixing assembly 2. When the two are sleeved and embedded with each other, the support fixing connecting assembly 3 is inclined. At this time, the support fixing connecting assembly 3 and the support fixing assembly 2 form a composite support body. When the H-shaped steel structure body 1 bears the force, the support fixing connecting assembly 3 and the support fixing assembly 2 can cooperate to disperse and transmit the load from the H-shaped steel structure body 1. Through the inclined arrangement, the force is decomposed into axial pressure and vertical axial component. The axial pressure is sequentially transmitted to the horizontal column and the vertical column of the H-shaped steel structure body 1 along the assembly structure. The vertical axial component effectively balances the horizontal displacement trend of the H-shaped steel structure body 1 caused by the load, significantly improves the stability and carrying capacity of the H-shaped steel structure body 1 under complex stress conditions, and guarantees the structural safety and normal use function.

[0033] The improvement of the embodiment is that:

[0034] Considering that the connection of the H-shaped steel structure only relies on the connection node of the vertical and horizontal members to bear the load, when facing larger load, especially complex combined load, the connection is prone to local damage due to stress concentration, which further causes local deformation, cracking and other damage, seriously damaging the integrity and carrying capacity of the connection node. Therefore, the support fixing assembly 2 and the support fixing connecting assembly 3 are arranged in an inclined state, which can provide inclined support force for the H-shaped steel structure body 1. Since the connection of the H-shaped steel structure body 1 is prone to local damage due to stress concentration, the support fixing assembly 2 and the support fixing connecting assembly 3 share the load at the connection node, reduce the stress concentration phenomenon, and protect the integrity and carrying capacity of the connection node. The support fixing assembly 2 and the support fixing connecting assembly 3 are connected by sleeving to form a whole, which enhances the connection strength between them, makes them more reliable when transmitting load, and is not easy to loosen or fall off. Moreover, the sleeving installation makes the support fixing assembly 2 and the support fixing connecting assembly 3 can be quickly aligned, which is convenient for installation operation on the construction site and improves the construction efficiency.

The end of the first support inclined rod 22 away from the first horizontal rod connecting frame 21 is fixedly connected with a first vertical connecting frame 23. The surface of the first vertical connecting frame 23 is sleeved on the surface of the vertical column.

[0036] The first vertical connecting frame 23 is fixedly connected with two fixed frames 24 on the surface, and a steel wire 240 is sleeved on the inner wall of the fixed frame 24.

[0037] By tightly sleeving the first vertical connecting frame 23 on the surface of the vertical column, the partial vertical force transmitted by the first support inclined rod 22 is transmitted to the vertical column, thereby sharing part of the load pressure of the vertical column. Meanwhile, the first horizontal rod connecting frame 21 is sleeved on the surface of the horizontal column to provide horizontal connection for the entire support fixed assembly 2. When the horizontal column is subjected to bending moment due to vertical load or horizontal load, the first horizontal rod connecting frame 21 can transmit the force to the first support inclined rod 22. By inserting the steel wire 240 into the fixed frame 24 and tightening, the first vertical connecting frame 23 and the vertical column are more stable, and the first vertical connecting frame 23 is prevented from moving on the surface of the vertical column when the H-shaped steel structure body 1 is shaken by external factors.

[0038] In order to enable the support fixed assembly 2 to be sleeved with the support fixed connecting assembly 3 to form a support body, the first horizontal rod connecting frame 21 is fixedly connected with a limiting block 210 at the bottom. The limiting block 210 is sleeved on the inner cavity of the support fixed connecting assembly 3, and the sleeving cooperation between the limiting block 210 and the inner cavity of the support fixed connecting assembly 3 enables the support fixed assembly 2 to be sleeved with the support fixed connecting assembly 3.

[0042] In order to make the connection of the first horizontal rod connecting frame 21 and the second horizontal rod connecting frame 31 more stable, and make the limiting block 210 not slide on the inner wall of the limiting groove 310, therefore, the first connecting plate 211 is fixedly connected to the surface of the first horizontal rod connecting frame 21, the second connecting plate 311 is fixedly connected to the surface of the second horizontal rod connecting frame 31, the bottom of the first connecting plate 211 is in contact with the top of the second connecting plate 311, and the first connecting plate 211 and the second connecting plate 311 are connected through bolts, when the first horizontal rod connecting frame 21 and the second horizontal rod connecting frame 31 are in contact, at this time, the limiting block 210 is located on the inner wall of the limiting groove 310, and the first connecting plate 211 and the second connecting plate 311 will be contacted, at this time, the first connecting plate 211 and the second connecting plate 311 are fixedly connected through the bolts, so that the supporting and fixing assembly 2 and the supporting and fixing connecting assembly 3 form an integral whole to support the H-shaped steel structure body 1.
