[0015] 1. In the utility model, an assembly component for connecting other steel structure bodies is arranged on the steel structure body, and the connecting plate in the assembly component directly connects the two steel structure bodies together, thereby preventing the steel structure bodies from shaking during the assembly process. At the same time, the blocking rods arranged on both sides thereof can be directly placed in the positioning grooves on the docking rods, thereby forming a limiting structure on both sides of the steel structure body, so as to achieve the purpose of quickly limiting the steel structure body, so that the steel structures can be quickly docked together.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides an assembled fireproof steel structure, including a steel structure body 1, one side of the steel structure body 1 is fixedly connected with an assembly component 2 by bolts, the assembly component 2 is symmetrically distributed along the center point of the steel structure body 1, a reinforcement frame 4 is fixedly installed on the top of the steel structure body 1, one end of the steel structure body 1 is fixedly connected with a cross reinforcement plate 3, the assembly component 2 includes a blocking rod 21, a connecting plate 22 and a docking rod 26, the connecting plate 22 is fixedly installed at the intersection of two steel structure bodies 1, the docking rod 26 is fixedly installed on one side of the connecting plate 22, one end of the blocking rod 21 is rotatably connected with a connecting head 25, the connecting head 25 is welded to the other side of the connecting plate 22, one end of the connecting head 25 is overlapped on the docking rod 26 on one side of the other connecting plate 22, a positioning groove 28 is provided at the intersection of the docking rod 26 and the blocking rod 21, a positioning rod 27 is fixedly installed inside the connecting plate 22, the positioning rod 27 is inserted into the inside of the steel structure body 1, and a reinforcement sheet 5 is fixedly installed on the outer wall of the steel structure body 1.

[0026] The specific configuration and function of this embodiment are described in detail below. Two adjacent steel structure bodies 1 are connected together through an assembly assembly 2. The steel structure body 1 itself is structurally reinforced through a reinforcement frame 4 at the top and a cross reinforcement plate 3 at the end to ensure its own structural stability and strength. At the same time, a reinforcement sheet 5 is also synchronously arranged on the steel structure body 1 itself to reinforce the steel structure body 1 itself.

[0027] The assembly component 2 is used to connect two steel structure bodies 1. During assembly, the connecting plate 22 is first connected to the two steel structure bodies 1 using the positioning rod 27. Then, the blocking rod 21 is rotated in the vertical direction. The connecting head 25 will determine the rotation center of the blocking rod 21. The blocking rod 21 is rotated to overlap one end of the blocking rod 21 on the positioning groove 28 of the docking rod 26. The blocking rod 21 is used to form a limiting structure on both sides of the steel structure body 1 to prevent the steel structure from shaking left and right, thereby fixing the steel structure body 1.

[0028] Embodiment 2

[0029] like Figure 3 and Figure 4 As shown, a protrusion 23 is fixedly installed on the outer wall of the connecting plate 22, and a movable rotating rod 24 is rotatably connected inside the protrusion 23. A positioning hole 29 is opened at one end of the blocking rod 21, and a limiting end 210 is fixedly installed at one end of the movable rotating rod 24, and one end of the limiting end 210 is inserted into the inside of the positioning hole 29.

[0030] The effect achieved by the entire embodiment is that the movable rotating rod 24 is installed on the protrusion 23 and can only rotate on the horizontal plane. After one end of the blocking rod 21 is placed on the docking rod 26, the movable rotating rod 24 is immediately rotated to insert the limiting end 210 at its end into the positioning hole 29 to complete the limiting of the blocking rod 21. The rotation range of the blocking rod 21 is on the vertical plane, while the rotation range of the movable rotating rod 24 is on the horizontal plane. Therefore, the movable rotating rod 24 will prevent the blocking rod 21 from rotating, and the blocking rod 21 can also limit the movable rotating rod 24, achieving a mutual locking effect, thereby ensuring the structural stability of the assembly component 2.

[0031] The use method and working principle of the device: The steel structure body 1 is connected together through the assembly components 2, and the steel structure body 1 is structurally reinforced by the reinforcement frame 4 at the top and the cross reinforcement plate 3 at the end, so as to ensure its own structural stability and structural strength;

[0032] During assembly, the two steel structure bodies 1 are first connected with the connecting plate 22, and then the blocking rod 21 is rotated in the vertical direction so that one end of the blocking rod 21 overlaps the positioning groove 28 of the docking rod 26. At this time, the movable rotating rod 24 is immediately rotated to insert the limiting end 210 at its end into the positioning hole 29 to complete the limiting of the blocking rod 21. Since the rotation range of the blocking rod 21 is on the vertical plane, and the rotation range of the movable rotating rod 24 is on the horizontal plane, the movable rotating rod 24 will prevent the blocking rod 21 from rotating, and the blocking rod 21 can also limit the movable rotating rod 24, so as to achieve the effect of mutual locking;

[0033] A limiting structure is formed on both sides of the steel structure body 1 by using the blocking rod 21 to prevent the steel structure from shaking left and right, ensure the structural stability of the assembly component 2, and achieve the purpose of quickly limiting the steel structure body 1, so that the two steel structure bodies 1 can be quickly connected together.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
