Description

Technical Field

[0001] This utility model belongs to the field of sleeve reinforcement technology, specifically relating to an assembled sleeve reinforcement device for steel components. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The instability and failure of space frame structures are mainly due to the presence of numerous members, primarily circular steel tubes. These tubes have a large slenderness ratio and are relatively thin. Under stress, stress concentration points often appear at the compression members. Instability in these members reduces the overall stability of the space frame, leading to its collapse. Stress concentration in compression members of space frame structures is often related to unreasonable design, construction problems, and improper use. For compression members in high-stress areas, even minor external disturbances can cause buckling deformation, leading to stress concentration displacement, reduced load-bearing capacity, and potentially localized or even complete collapse. Therefore, when deformation occurs in members of a space frame structure, they should be reinforced or replaced as soon as possible to avoid incalculable losses of life and property.

[0004] In practical use, some buildings may experience insufficient load-bearing capacity and become unusable due to renovations, additions of facilities, or other reasons. Demolishing and rebuilding a space frame structure is uneconomical, time-consuming, and labor-intensive, and it is desirable to retain the original functionality of the space frame structure. Therefore, it is necessary to reinforce and improve existing space frame structures to alter their stress characteristics and enhance their load-bearing capacity. Utility Model Content

Furthermore, it features simple construction, good quality control, and easy replacement during structural operation and maintenance, making it widely applicable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The first connector is provided at both ends of the first reinforcement member, and the second reinforcement member is provided at both ends of the second connector. The inner surfaces of the first and second reinforcement members are flat. A rod is installed between the first and second reinforcement members.

[0025] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0026] In practical use, some buildings may experience insufficient load-bearing capacity and become unusable due to renovations, additions of facilities, or other reasons. Demolishing and rebuilding a space frame structure is uneconomical, time-consuming, and labor-intensive, and it is desirable to retain the original functionality of the space frame structure. Therefore, it is necessary to reinforce and improve existing space frame structures to alter their stress characteristics and enhance their load-bearing capacity.

[0027] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses an assembled sleeve reinforcement device for steel components, such as... Figure 1 As shown, the device includes a first reinforcing member 1, a second reinforcing member 3, a first connecting member 2, and a second connecting member 4. The first reinforcing member 1 has first connecting members 2 at both ends, and the second connecting member 4 has second reinforcing members 3 at both ends. The inner surfaces of the first reinforcing member 1 and the second reinforcing member 3 are flat. The rod to be reinforced is enclosed between the first reinforcing member 1 and the second reinforcing member 3. There is a gap between the outer surface of the rod and the first connecting member 2, and a gap between the outer surface of the rod and the second connecting member 4. The inner surfaces of the first reinforcing member 1 and the second reinforcing member 3 are hollow, and there are sealing plates at both ends for fixing.

[0028] The reinforcing plate is a square steel plate, and the connecting parts are ear plates. During reinforcement, the load is applied secondaryly, resulting in a certain degree of load lag. The reinforcement process simply involves placing two semi-square steel plates on both sides of the structural member and connecting them using reinforcing bolts 5 via the ear plates; welding is not required, thus minimizing the requirements for the on-site construction environment. Considering the initial defects and deflection of the round steel pipe members at the factory, coupled with the deflection that occurs during daily use, a structure with left-right contact and top-bottom gaps is used for reinforcement.

[0029] In use, align the first connector 2 at both ends of the first reinforcement member 1 and the second connector 4 at both ends of the second reinforcement member 3, so that the rod 7 is clamped between the first reinforcement member 1 and the second reinforcement member 3, and ensure that both ends of the rod 7 are in close contact with the inner surfaces of the first reinforcement member 1 and the second reinforcement member 3. The rod has a gap 8 between itself and the sides of the first connector 2 and the second connector 4 respectively. Then, tighten the reinforcing bolts 5, so that the reinforcing bolts 5 pass through the threaded holes of the first connector 2 and the second connector 4 in sequence. Then, tighten the reinforcing nuts 6 at the ends of the fixing bolts to achieve the reinforcement of the rod. In addition, a certain gap is left between the outer surface of the rod 7 and the upper and lower contact surfaces of the first connector 2 and the second connector 4. The existence of a certain gap between the rod 7 and the sleeve has a certain beneficial effect on the reinforcement effect. Therefore, when the rod 7 is compressed and the rod 7 is displaced and contacts the upper and lower surfaces of the square sleeve, it has a restraining effect on the bending deformation of the rod.

[0030] The first reinforcing member 1 is fixedly connected to the first connecting member 2, and the second reinforcing member 3 is fixedly connected to the second connecting member 4. The second reinforcing member 3 is provided at the lower end of the first reinforcing member 1, and a rectangular cavity is formed in the middle after the first reinforcing member 1 and the second reinforcing member 3 are joined together. The outer surface of the rod is in close contact with the inner surface of the first reinforcing member 1 and the second reinforcing member 3.

[0031] Currently, welding is the most common method for connecting the first reinforcement member 1 and the second reinforcement member 3. This connection method has high requirements for the on-site construction environment, which has a significant impact on welding quality and requires highly skilled welders. If welding defects occur, the weld seam and its vicinity will become high-stress areas, thereby reducing the strength of member 7 and affecting its reinforcement effect. Furthermore, the welding process can easily cause severe secondary stress, secondary damage, or section weakening to the structure. Therefore, a bolted assembly reinforcement method is preferred.

[0032] like Figure 2As shown, threaded holes are provided at both ends of the first connecting member 2, and reinforcing bolts 5 are installed in the threaded holes. Reinforcing nuts 6 are installed at the ends of the reinforcing bolts 5. Threaded holes are also provided at both ends of the second connecting member 4, and the reinforcing bolts 5 are screwed into the threaded holes of the first connecting member 2 and the second connecting member 4 in sequence. The first connecting member 2 and the second connecting member 4 are detachably connected. The connecting members are connected by reinforcing bolts 5 and reinforcing nuts 6, forming a detachable connection. This design is characterized by simple construction, good quality control, and easy replacement during structural use, operation, and maintenance, making it applicable to a wider range of situations.

[0033] The lengths of the first reinforcing member 1 and the second reinforcing member 3 are less than the length of the rod. Furthermore, the optimal reinforcement effect is achieved when their lengths are 60% of the rod's length.

[0034] The first reinforcing member 1 and the second reinforcing member 3 are located at the middle of the member. The outer surfaces of both the first reinforcing member 1 and the second reinforcing member 3 are flat. The overall length of the reinforcing device is 60% of the length of the space frame member, and its thickness is the same as the thickness of the space frame member. Appropriate bolt preload is applied, and the device is fixed using reinforcing bolts 5 at both ends. At this point, the reinforcing device achieves the best reinforcement effect on the space frame member.

[0035] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
