Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure technology, specifically to a local reinforcement structure for steel structure nodes. Background Technology
[0002] Steel structures are widely used in large-scale buildings, bridges, and industrial plants due to their advantages such as high strength, light weight, and fast construction speed. Traditional steel structure joint reinforcement methods mostly involve welding reinforcing plates or bonding carbon fiber cloth. Welding reinforcement has a heat-affected zone, which may change the original steel properties and generate new residual stresses. It also places high demands on the construction environment and operators. Methods such as bonding carbon fiber cloth have extremely strict requirements on the surface treatment of the substrate, and their durability and peel resistance need to be tested. In addition, most of these methods are permanent reinforcements, which are not convenient for subsequent inspection, adjustment, or disassembly. In view of this, existing technologies may already have solutions to the above problems. However, this case aims to provide an alternative or replacement technical solution. Utility Model Content
[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a partial reinforcement structure for steel structure nodes, comprising a steel structure, wherein a reinforcement component is fitted onto the outer end of the steel structure;
[0004] The reinforcement components include: a first fixing frame, a support block, a second fixing frame, eight connecting brackets, and a locking assembly;
[0005] The first fixing frame is movably fitted onto the lower end of one side of the steel structure, and four first positioning through holes are provided on the outer side of the first fixing frame. The lower center of the support block is fixedly installed in the center of the first fixing frame, and the support block is movably embedded in the steel structure. The second fixing frame is movably fitted onto the upper end of one side of the steel structure, and four second positioning through holes are provided on the outer side of the second fixing frame. The eight connecting brackets are evenly distributed on the outer walls of the first fixing frame and the second fixing frame. The locking assembly passes through the four first positioning through holes and the four second positioning through holes at both ends.
[0006] Preferably, the locking assembly includes: four bolts and four nuts;
[0007] The bottom ends of the four bolts are movably inserted through the four first positioning through holes and the four second positioning through holes, and the four nuts are movably fitted onto the bottom ends of the four bolts.
[0008] Preferably, the size of the support block is smaller than the size of the steel structure.
[0009] Preferably, the connecting bracket is L-shaped.
[0010] Preferably, the support block is a cross-shaped support block.
[0011] Beneficial effects
[0012] This utility model provides a partial reinforcement structure for steel structure nodes, which has the following advantages: the reinforcement structure is stable and the stress is reasonable. The reinforcement system is formed by the first fixing frame, the second fixing frame and the cross-shaped support block, which effectively disperses the stress of the node and improves the bending, shear and deformation resistance of the node. The structure is easy to install and disassemble. It adopts bolt connection to achieve non-destructive installation without welding. The construction is fast and easy to maintain and adjust later. Its kit structure can be adapted to steel components of different specifications by adjusting the bolts. It has strong versatility, simple overall structure and low cost. In addition, the evenly distributed L-shaped connecting brackets enhance the connection rigidity and overall stability, prevent displacement and ensure the long-term effectiveness of the reinforcement effect.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example: Please refer to Figure 1-3 A partial reinforcement structure for a steel structure node includes a steel structure 1, with reinforcement components fitted onto the outer end of the steel structure 1.
[0019] The reinforcement components include: a first fixing frame 2, a support block 3, a second fixing frame 4, eight connecting brackets 5, and a locking assembly;
[0020] The first fixing frame 2 is movably fitted onto the lower end of one side of the steel structure 1, and four first positioning through holes are opened on the outer side of the first fixing frame 2. The support block 3 is fixedly installed at the center of the lower end of the first fixing frame 2 and is movably embedded in the steel structure 1. The second fixing frame 4 is movably fitted onto the upper end of one side of the steel structure 1, and four second positioning through holes are opened on the outer side of the second fixing frame 4. Eight connecting brackets 5 are evenly distributed on the outer walls of the first fixing frame 2 and the second fixing frame 4. The locking components are movably inserted through the four first positioning through holes and the four second positioning through holes at both ends.
[0021] In use, the operator first moves the steel structure 1 to the designated position, and then puts the first fixing frame 2 on the lower end of the steel structure 1 from one side. At the same time, the support block 3 on the first fixing frame 2 is aligned and inserted into the cavity of the steel structure 1. The support block 3 can provide radial support and positioning for the steel structure 1 to prevent the entire component from shaking. Then, the first fixing frame 2 is put on the upper end of the steel structure 1 from one side. The eight connecting brackets 5 are evenly distributed on the outer walls of the first fixing frame 2 and the second fixing frame 4. The connecting brackets 5 are mainly used to connect the fixing frame and the steel structure 1 to ensure connection rigidity and overall stability. Finally, the locking components are installed and pass through the four first positioning through holes and the four second positioning through holes respectively to achieve the effect of tightly clamping the upper and lower fixing frames on the steel structure 1.
[0022] In the specific implementation process, the locking assembly includes: four bolts 6 and four nuts 7;
[0023] The bottom ends of the four bolts 6 are movable through the four first positioning through holes and the four second positioning through holes, and the four nuts 7 are movably fitted onto the bottom ends of the four bolts 6.
[0024] During use, the operator installs four bolts 6 and inserts them into the four first positioning through holes and the four second positioning through holes respectively. Then, the nut 7 at the other end is tightened to clamp the upper and lower fixing brackets tightly onto the steel structure 1, completing the final fixing of the entire component. The locking component composed of bolts 6 and nuts 7 is used for connection and fixing, which can achieve quick installation and facilitate adjustment or replacement of reinforcement components.
[0025] In the actual implementation process, the size of support block 3 is smaller than that of steel structure 1.
[0026] During use, the support block 3 can be inserted into the steel structure 1 to provide radial support and positioning, preventing the entire component from shaking.
[0027] In the specific implementation process, the connecting bracket 5 is L-shaped.
[0028] During use, the L-shaped connecting bracket 5 helps to enhance stability and stress distribution.
[0029] In the specific implementation process, support block 3 is cross-shaped.
[0030] During use, the cross shape can make the structure more stable.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
