[0002] In the construction industry, the beam-column joint is the hub that connects the entire house frame and is an important part of the main structure of the house frame. The beam-column joint needs to have a strong strength bearing capacity to ensure the stability and safety of the overall frame structure in the construction project.
[0003] At the beam-column joint, steel bars can be tied and then concrete can be poured to fix the beam-column joint together. In order to strengthen the beam-column joint, diagonal supports are generally installed between the beams and columns. The two ends of the diagonal supports are respectively fixed on the beams and columns, so that the beams, columns and diagonal supports form a triangular stable structure.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] The present application embodiment discloses a reinforcement structure of a beam-column joint. Figure 1 and Figure 2 A reinforcement structure of a beam-column node includes a first support member 1, a second support member 2 and an oblique support member 3. The first support member 1 and the second support member 2 can be a rod-shaped structure or a long strip-shaped structure. The present embodiment is a long strip-shaped structure. The oblique support member 3 can be a rod-shaped structure or a long strip-shaped structure. It is best to have the same structure as the first support member 1 and the second support member 2. Therefore, the oblique support member 3 of the present embodiment is also a long strip-shaped structure. The first support member 1 and the second support member 2 are vertically fixedly connected. The two ends of the oblique support member 3 are respectively connected to the end of the first support member 1 and the end of the second support member 2, so that the first support member 1, the second support member 2 and the oblique support member 3 are spliced to form a triangular structure. The first support member 1 is attached to the lower surface of the beam 10, and the second support member 2 is attached to the outer peripheral side of the column 20. The second support member 2 is adaptively adjusted according to the cross-section of the column 20. If it is a cylindrical column 20, the second support member 2 is an arc plate. If it is a rectangular column 20, the second support member 2 is a straight plate.
[0034] Reference Figure 1 and Figure 2 The reinforcement structure of the beam-column node also includes a support body 4 for supporting the second support member 2, and the support body 4 stands on the ground. The part of the second support member 2 away from the beam 10 abuts against the support body 4, so that the first support member 1 can also be stably attached to the beam 10. The cooperation between the first support member 1 and the second support member 2 can increase the support area of the column 20 on the beam 10, and the first support member 1 and the second support member 2 can also play a role in reinforcing the beam-column node.
[0035] Reference Figure 3 In one embodiment, a positioning rod 11 is provided at a portion of the first support member 1 away from the second support member 2. Before installing the first support member 1, a hole for inserting the positioning rod 11 is first opened on the lower surface of the beam 10 so that the position of the first support member 1 installed on the beam 10 can be quickly determined.
[0036] Reference Figure 3 In one embodiment, the second support member 2 is inserted into the support body 4, and the first support member 1 is connected to the plug-in rod 12, and the plug-in rod 12 is inserted into the support body 4, so that when the second support member 2 is installed on the support body 4, the second support member 2 and the support body 4 maintain a relatively fixed state.
[0037] Reference Figure 2In one embodiment, the support body 4 includes two support blocks 41 and a telescopic assembly 42 installed between the two support blocks 41. The telescopic assembly 42 can change the height of the support body 4 by controlling the distance between the two support blocks 41. The support body 4 can adapt to bodies of different heights, thereby increasing the applicability of the support body 4.
[0038] Reference Figure 2 and Figure 3 In one embodiment, the telescopic assembly 42 includes two screws 421 and a threaded sleeve 422. One end of the two screws 421 is rotatably connected to the two support blocks 41 respectively, and the ends of the two screws 421 close to each other are threadedly connected to the threaded sleeve 422. The threaded sleeve 422 has a forward thread and a reverse thread, and the rotation directions of the two screws 421 are also opposite. When the threaded sleeve 422 is rotated, the two screws 421 can be driven to move closer to or away from each other, thereby changing the length of the support body 4.
[0039] When the length of the support body 4 is fixed, the threaded sleeve 422 is provided with a fixing portion for fixing the two screw rods 421. The fixing portion may be a cast concrete column 40, and the threaded sleeve 422 is provided with a casting hole for concrete to enter the threaded sleeve 422. After the concrete is filled in the threaded sleeve 422, the two screw rods 421 are formed as a whole through the concrete column 40, so that the support body 4 can stably support the first support member 1 and the second support member 2.
[0040] Reference Figure 3 and Figure 4 In one embodiment, the reinforcement structure of the beam-column node further includes a reinforcing rod 5. When the support body 4 supports the second support member 2, the distance between the two support blocks 41 remains unchanged. The reinforcing rod 5 is interference-fitted between the two support blocks 41, thereby increasing the support strength of the support body 4. A positioning groove for the reinforcing rod 5 to be inserted is provided on the support block 41, and the positioning groove can determine the installation position of the reinforcing rod 5 on the support block 41.
[0041] Reference Figure 4 In one embodiment, the reinforcing rod 5 is provided with a protective plate 6, and the protective plate 6 is fixedly mounted on the reinforcing rod 5. When multiple supporting bodies 4 are installed, the multiple supporting bodies 4 are evenly spaced and distributed on the outer peripheral side of the column 20. The second supporting member 2 corresponds to the supporting body 4 one by one, and the reinforcing rod 5 also corresponds to the supporting body 4 one by one.
[0042] Reference Figure 4 In one embodiment, the upper end of the protection plate 6 contacts the oblique support member 3, and the protection plate 6 is fixedly mounted on the support body 4 through the reinforcing rod 5. The protection plate 6 can also support the oblique support member 3, and also strengthen the reinforcement effect of the beam-column node.
[0043] Reference Figure 5After the reinforcing rod 5 is installed on the supporting body 4, the protective plates 6 between the multiple supporting bodies 4 are spliced together, and the spliced protective plates 6 can shield the supporting body 4. If it is a cylindrical column 20, the protective plate 6 is an arc plate, and if it is a rectangular parallelepiped column 20, the protective plate 6 is a straight plate structure.
[0044] The implementation principle of a reinforcement structure of a beam-column node in the embodiment of the present application is:
[0045] When reinforcing the intersection of beams and columns, first insert the positioning rod 11 of the first support member 1 into the hole on the beam 10, and then insert the plug-in rod 12 of the second support member 2 into the support body 4, rotate the threaded sleeve 422 to make the other support block 41 abut against the ground, and the support body 4 can achieve the effect of stable support for the first support member 1 and the second support member 2. The first support member 1 and the second support member 2 are stably installed between the intersection of the beams and columns, which can reinforce the beam-column node. Finally, the reinforcing rod 5 is interference fit into the two support blocks 41. When all the reinforcing rods 5 are interference fit into the corresponding support bodies 4, multiple protective plates 6 can shield the support bodies 4, and the protective plates 6 are also in contact with the inclined support members 3, which can further reinforce the beam-column nodes.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
