Description

Technical Field

[0001] This utility model relates to a modular beam-column joint reinforcement structure. Background Technology

[0002] In the field of building structural engineering, beam-column joints, as the core components that transfer loads and ensure the overall stability of the structure, have always been a focus of industry attention in terms of reinforcement technology. Currently, existing beam-column joint reinforcement methods are mainly divided into traditional on-site casting reinforcement, external steel reinforcement, and fiber-reinforced composite material reinforcement. However, these technologies all have significant shortcomings in practical applications and are difficult to meet the requirements of modern buildings for reinforcement efficiency, structural stability, and adaptability. Traditional on-site casting reinforcement requires setting up formwork and tying reinforcing bars at the joint before pouring concrete. This not only involves complex on-site procedures and a long construction period, but also makes the concrete curing process susceptible to environmental influences, making it difficult to guarantee the quality of the pouring. Furthermore, wet work can interfere with the normal use of the building's interior, making it particularly unsuitable for the renovation and reinforcement of existing buildings. While external steel reinforcement can improve the load-bearing capacity of the joint, the connection between the steel and the beams and columns largely relies on welding, resulting in a large amount of on-site welding work. In addition, the steel components need to be cut and processed on-site according to the joint dimensions, leading to poor adaptability and an inability to flexibly handle beam and column joints of different specifications. If adjustments or maintenance are needed later, disassembly and reassembly are extremely difficult. While fiber-reinforced composite reinforcement offers advantages such as lightweight and corrosion resistance, the bonding effect between the material and the beam / column surface is easily affected by the flatness of the base layer and environmental humidity. Long-term use can lead to peeling, resulting in a decrease in reinforcement effectiveness. Furthermore, this method can only improve the local shear resistance of the joint and cannot form an overall load-bearing system. When subjected to large loads or seismic forces, the joint is still at risk of deformation and damage. Utility Model Content

[0003] In view of the shortcomings of the background technology, this utility model provides a modular beam-column joint reinforcement structure, which precisely engages with the reinforced connection part through rectangular snap-fit, and uses support members to provide stable support for the bottom of the reinforced connection part, forming a multi-directional force support system; at the same time, each component is modular, simplifying the installation steps and improving work efficiency.

[0004] To achieve the above objectives, this utility model provides a modular beam-column joint reinforcement structure, including a first column structure. The upper side wall of the first column structure is provided with a rectangular slot and a support member. The support member is located below the rectangular slot. A reinforcing connection part is engaged at the rectangular slot. The reinforcing connection part is used to connect the beam structure. The upper end of the reinforcing connection part is connected to a second column structure.

[0005] Furthermore, the support member is a corbel, which is a long strip with a right-angle bend, and is welded or bolted to the first column structure.

[0006] Furthermore, the rectangular bayonet has four slots.

[0007] Furthermore, the reinforced connection includes a first connector, which is snapped into a rectangular slot and its bottom abuts against the support to form a platform. The first connector includes an L-shaped plate, with a vertical plate vertically connected to the vertical end face of the L-shaped plate. The end of the vertical plate near the interior of the first column structure is provided with a socket. A limiting block is provided on the horizontal end face of the L-shaped plate, and multiple first through holes are provided on the side wall of the horizontal end face.

[0008] Furthermore, the reinforcing connection also includes a second connector, which includes a central rectangular tube. The side wall of the central rectangular tube is provided with an insertion port corresponding to the socket. The central rectangular tube is connected to a plurality of inverted U-shaped plates through a connecting frame. The two vertical end faces of the inverted U-shaped plates are provided with corresponding second through holes corresponding to the first through hole.

[0009] Furthermore, the outer wall of the central rectangular tube, the inner wall of the first column structure, the vertical plate, and the connecting frame form multiple insertion interfaces.

[0010] Furthermore, a triangular plate is welded to the upper surface of each of the inverted U-shaped plates.

[0011] Furthermore, the bottom four inner walls of the second column structure are provided with plug-in blocks with an isosceles trapezoidal cross section, and the plug-in blocks have a vertical latch in the middle; the bottom four outer walls of the second column structure are all welded with triangular plates, and the triangular plates are welded to the upper surface of the inverted U-shaped plate.

[0012] Furthermore, the bottom four inner walls of the second column structure are provided with plug-in blocks with an isosceles trapezoidal cross section, and the plug-in blocks have a vertical bayonet in the middle; the bottom four outer walls of the second column structure are welded with hollow triangular plates, and the hollow triangular plates are bolted to the triangular plates on the inverted U-shaped plate.

[0013] Furthermore, the beam structure end is provided with a limiting groove corresponding to the limiting block, the limiting groove space is slightly larger than the limiting block volume and the inner wall of the limiting groove is provided with an elastic layer.

[0014] Beneficial effects: 1. This application uses a rectangular snap-fit ​​joint to precisely engage with the reinforced connection part, and with the support member (bracket) to provide stable support for the bottom of the reinforced connection part, a multi-directional force support system is formed. The second column structure further strengthens the overall connection through the cooperation of the plug-in block and the plug interface, and the welding or bolting of the triangular plate, effectively dispersing the stress at the beam-column joint, greatly improving the shear and bending resistance of the joint, ensuring that the structure can remain stable when subjected to large loads, and significantly improving the load-bearing performance and structural safety of the beam-column joint. 2. The components of this application adopt a modular design. For example, the first connector, the second connector, and the support can all be prefabricated in advance. On-site assembly can be completed simply by snapping, welding, or bolting. There is no need for complicated on-site processing procedures, which greatly shortens the installation period and reduces the difficulty and labor intensity of on-site construction.

The corbel 3-1 is a long strip with a right-angle bend. The corbel 3-1 is welded or bolted to the first column structure 1 (only the welded structure is shown in the figure; the bolted connection is prior art and will not be described in detail here). Preferably, this application provides four rectangular slots 2, and the rectangular slots 2 are connected to reinforcing connection parts 4. The reinforcing connection parts 4 are used to connect beam structures 9, and the upper end of the reinforcing connection parts 4 is connected to a second column structure 5. The setting of the reinforcing connection parts 4 is more robust than the traditional bolted connection.

[0019] Specifically, such as Figure 8 As shown, the reinforcing connection part 4 includes a first connector 6, which is inserted into a rectangular slot 2 and its bottom abuts against the corbel 3-1, forming a platform for placing the beam structure 9 together with the corbel 3-1. The first connector 6 includes an L-shaped plate 6-1, with a vertical plate 6-2 vertically connected to its vertical end face. The end of the vertical plate 6-2 near the interior of the first column structure 1 has a socket 6-3 for connecting the second connector 7. A limiting block 6-4 is provided on the horizontal end face of the L-shaped plate 6-1, and multiple first through holes 6-5 are provided on the side wall of the horizontal end face. Figure 7 As shown, the second connecting member 7 includes a central rectangular tube 7-1. The side wall of the central rectangular tube 7-1 has an insertion port 7-2 corresponding to the socket 6-3. The central rectangular tube 7-1 is connected to multiple inverted U-shaped plates 7-4 via a connecting bracket 7-3. The two vertical end faces of the inverted U-shaped plates 7-4 have corresponding second through holes 7-5 corresponding to the first through hole 6-5. The first through holes 6-5 and the second through holes 7-5 are connected by bolts. This application provides two structures for the inverted U-shaped plates 7-4, such as... Figure 7 As shown, the first type of inverted U-shaped plate 7-4 is integral. (As shown...) Figure 13 As shown, another type of inverted U-shaped plate 7-4 includes a horizontal plate, with T-shaped slots symmetrically provided on both sides of the bottom of the horizontal plate and a first threaded hole provided on the side wall of the horizontal plate corresponding to the T-shaped slot. A vertical plate is engaged with the T-shaped slot, and a second threaded hole is provided on the vertical plate corresponding to the first threaded hole.

[0020] For reference Figure 7As shown, the connecting frame 7-3 includes a rectangular frame and four diagonally extending diagonal rods from the rectangular frame. The ends of the diagonal rods are connected to the outer wall of the central rectangular tube 7-1, and the outer perimeter of the rectangular frame is connected to the inverted U-shaped plate 7-4. The outer wall of the central rectangular tube 7-1, the inner wall of the first column structure 1, the vertical plate 6-2, and the connecting frame 7-3 form multiple insertion interfaces 10. In this application, there are four insertion interfaces 10.

[0021] For reference Figure 1 As shown, this application provides two embodiments for the connection between the reinforcing connection part 4 and the second column structure 5. The first embodiment is as follows: each of the four inner walls at the bottom of the second column structure 5 is provided with an insert block 5-1 with an isosceles trapezoidal cross section. The insert block 5-1 is provided with a vertical bayonet 5-2 in the middle. Each of the four outer walls at the bottom of the second column structure 5 is welded with a triangular plate 8. The triangular plate 8 is welded and fixed to the upper end face of the inverted U-shaped plate 7-4.

[0022] The second embodiment is as follows: Figure 11 As shown, the bottom four inner walls of the second column structure 5 are each equipped with an isosceles trapezoidal insertion block 5-1. Each insertion block 5-1 has a vertical latch 5-2 in the center. The bottom four outer walls of the second column structure 5 are each welded with a hollow triangular plate 8. A triangular plate 8 is also welded onto the inverted U-shaped plate 7-4. The hollow triangular plate 8 is aligned with the triangular plate 8 on the inverted U-shaped plate 7-4 and inserted. After insertion, a bolt is used to achieve the connection. The above two embodiments can be selected according to the actual situation.

[0023] For reference Figure 10 As shown, beam structure 9 includes an I-beam with connecting blocks at both ends. Each connecting block has a limiting groove 9-1 corresponding to the limiting block 6-4. The limiting groove 9-1 and the limiting block 6-4 are funnel-shaped, with the limiting groove 9-1 having a slightly larger volume than the limiting block 6-4. The inner wall of the limiting groove 9-1 has an elastic layer 9-2, which provides a certain buffering effect. The limiting groove 9-1 engages with the limiting block 6-4 to restrict the beam structure 9 laterally. Subsequently, the beam structure 9 is vertically restricted through the connection between the second connecting part and the first connecting part, ensuring the stability and firmness of the connection.

[0024] Working method: A rectangular slot 2 and an installation bracket 3-1 are pre-cut in the column structure. Then, the first connector 6 is inserted into the rectangular slot 2 and the limiting groove 9-1 at the end of the beam structure 9 is inserted into the limiting groove 9-1 of the first connector 6 to achieve the initial fixation of the position of the beam structure 9. Then, the second connector 7 is installed. The inverted U-shaped plate 7-4 is inserted downward to enclose the beam structure 9 and the L-shaped plate 6-1. Then, the connection is achieved by bolts through the through holes of the inverted U-shaped plate 7-4 and the L-shaped plate 6-1. After the reinforcing connection part 4 is installed on the beam structure 9, the plug block 5-1 of the second column structure 5 is inserted into the plug interface 10 of the reinforcing connection part 4. Then, the triangular plate 8 of the second column structure 5 is welded and fixed to the inverted U-shaped plate 7-4 or the connection between the second column structure 5 and the inverted U-shaped plate 7-4 is achieved by bolts.
