[0015] The assembly method of the prefabricated concrete frame joint connection auxiliary device includes the following steps:

[0016] S1. When assembling and connecting the prefabricated concrete frame nodes, the support plate can rotate freely through the connection of the first connecting rod and the first rotating block. When the support plate rotates downward to the flat position, the support plate and the locking block can be locked by the setting of the wedge block in the side groove. After the support plate is rotated to the flat position, the beam body can be assembled.

[0017] S2. Hoist the crossbeam body to the upper side of the two columns, calibrate the position of the crossbeam body so that the splicing plates on both sides are aligned with the position of the columns, and then move the crossbeam body down to dock and assemble it with the columns.

[0018] S3. The beam body moves down so that the center rod can be inserted into the center hole and the pre-embedded threaded rod can be inserted into the fastening hole. After the connection is completed, the ring and the positioning plate are respectively placed on the outside of the center rod and the pre-embedded threaded rod.

Subsequently, in conjunction with the upper installation structure, it can protect the installation position of the pre-embedded threaded rod.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During use, when assembling and connecting prefabricated concrete frame nodes, after the beam body is installed, the positioning rod is fully inserted into the positioning hole, and the support plates on both sides provide support for the bottom sides of the beam body. The pressure and vibration generated by the beam body after installation will be transmitted to the support plate position. The pressure and vibration on the support plate will be transmitted to the first damper and the first spring position through the locking block. While the pre-embedded threaded rod of the beam body and the column itself is in a rigid connection to ensure stability, the pressure is distributed to the bottom of the beam body. The pressure-distributing part is in a soft connection for buffer support, which can provide a certain deformation capacity for the assembly and fixing position of the beam body and the column, so that the building structure can undergo a certain displacement and deformation when affected by external forces, vibrations or earthquakes, better adapt to different environmental conditions, reduce the vibration response of the structure, and thus protect the safety of the building and people.

[0022] 2. During use, after the assembly and fixing are completed, the ring and the positioning plate are clamped and fixed between the nut and the splicing plate. During the construction process, the force on the pre-embedded threaded rod and the nut can be distributed by the ring and the positioning plate, which can prevent the nut from loosening due to the force on a single pre-embedded threaded rod. It plays a good role in fastening and preventing loosening of the nut installation position, and improves the stability of the beam body and column assembly.

[0023] 3. In use, the end face of the crossbeam body is spliced ​​with the first baffle and the second baffle to form a frame. The frame is located outside the installation position of the pre-embedded threaded rod. Subsequently, in conjunction with the upper installation structure, it can protect the installation position of the pre-embedded threaded rod, avoid the pre-embedded threaded rod and nut from being exposed to the outside for a long time and rusting and damage, and improve the service life of the building structure.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-9As shown: A prefabricated concrete frame node connection auxiliary device includes: two columns 1, two sets of first baffles 7 and two sets of assembly bolts 8. The first baffles 7 are fixedly installed on the outer surfaces of both sides of the columns 1 by the assembly bolts 8. A center rod 5 is fixedly connected to the center of the top of the columns 1, and pre-embedded threaded rods 6 are provided at the corners of the top of the columns 1; a crossbeam assembly 2, which is located on the upper side of the two columns 1. The crossbeam assembly 2 includes a crossbeam body 201. Side plates 202 are fixedly connected to the outer surfaces of both sides of the crossbeam body 201, and splicing plates 203 are fixedly connected to the outer surfaces of the side plates 202; a butt joint assembly 3, which has two components. The two butt joint assemblies 3 are fixedly connected to the outer surfaces of the two columns 1 near the crossbeam body 201. The butt joint assembly 3 includes a first connecting seat 301; and a support assembly 4, which has two components. The two support assemblies 4 are fixedly connected to the outer surfaces of the two columns 1 near the lower side of the first connecting seat 301. The support assembly 4 includes a support frame 401.

[0037] like Figure 5 and Figure 6 As shown, fastening holes 204 are provided at the top corners of the splicing plate 203, and a center hole 205 is provided at the center of the top of the splicing plate 203. A ring 206 is provided at the top of the splicing plate 203 near the center hole 205. Multiple positioning plates 207 are uniformly fixedly connected to the outer surface of the ring 206. Nuts 208 are provided on the top of the multiple positioning plates 207. When splicing and assembling the crossbeam body 201 and the column 1, the crossbeam body 201 is hoisted to the upper side of the two columns 1, and the position of the crossbeam body 201 is calibrated so that the splicing plates 203 on both sides are aligned with the position of the columns 1 respectively. Then the crossbeam body 201 is lowered to dock and assemble with the columns 1.

[0038] like Figure 6 As shown, the ring 206 is fitted onto the outer side of the central rod 5. The top of the positioning plate 207 has a mounting hole, the inner surface of which engages with the outer surface of the pre-embedded threaded rod 6. The inner surface of the nut 208 is threadedly connected to the outer surface of the pre-embedded threaded rod 6. Moving the crossbeam body 201 downwards allows the central rod 5 to be inserted into the central hole 205, and the pre-embedded threaded rod 6 to be inserted into the fastening hole 204. After the connection is complete, the ring 206 and the positioning plate 207 are respectively fitted onto the outer sides of the central rod 5 and the pre-embedded threaded rod 6. Then, the nut 208 is tightened on the outer side of the pre-embedded threaded rod 6 to secure it. The assembly and fixing of the beam body 201 and the column 1 are completed. After the assembly and fixing are completed, the ring 206 and the positioning plate 207 are clamped and fixed between the nut 208 and the splicing plate 203. During the construction process, the force on the pre-embedded threaded rod 6 and the nut 208 can be distributed by the ring 206 and the positioning plate 207, thereby avoiding the nut 208 from loosening due to the force on a single pre-embedded threaded rod 6. This plays a good role in fastening and preventing loosening of the nut 208, and improves the stability of the assembly of the beam body 201 and the column 1.

[0039] like Figure 7 As shown, multiple positioning rods 209 are fixedly connected to both sides of the lower surface of the crossbeam body 201. A first connecting rod 302 is rotatably connected to the inner surface of the first connecting seat 301. A first rotating block 303 is fixedly connected to the outer surface of the first connecting rod 302. A support plate 304 is fixedly connected to the outer surface of the first rotating block 303. Before assembling the crossbeam body 201, the support plate 304 can rotate freely through the connection of the first connecting rod 302 and the first rotating block 303. After rotating the support plate 304 to a flat position, the crossbeam body 201 can be assembled.

[0040] like Figure 5 and Figure 7 As shown, positioning holes 305 are provided at the top corners of the support plate 304. The outer surface of the positioning rod 209 is inserted into the inner surface of the positioning hole 305. A bottom groove 306 is provided at the bottom of the support plate 304, and side grooves 307 are provided on the inner surfaces of both sides of the bottom groove 306. When the crossbeam body 201 is assembled with the column 1, while the center rod 5 and the pre-embedded threaded rod 6 are being aligned and aligned, the positions of the positioning rod 209 and the positioning hole 305 are being aligned. After confirming that the positioning rod 209 and the positioning hole 305 are aligned and in a vertical position, the crossbeam body 201 is moved down. During assembly, after the beam body 201 is lowered, the positioning rod 209 is inserted into the positioning hole 305. The cooperation between the positioning rods 209 on both sides and the positioning hole 305 can calibrate and position the lateral tilt angle of the beam body 201, so that the beam body 201 can be kept in a horizontal position to complete the assembly. After the installation is completed, the setting of the positioning rod 209 inserted into the positioning hole 305 can provide lateral reinforcement to the beam body 201, improve the lateral bearing capacity of the beam body 201, and thus improve the overall structural strength of the prefabricated concrete frame.

[0041] like Figure 8As shown, a support plate 403 is fixedly connected to the top of the support frame 401. First dampers 404 are fixedly connected to the top corners of the support plate 403. First springs 405 are fitted onto the outer surfaces of multiple first dampers 404. A locking block 406 is fixedly connected between the upper surfaces of the multiple first dampers 404. The locking block 406 is located inside the bottom groove 306. Mounting grooves 407 are formed on both outer surfaces of the locking block 406. Second springs 408 are symmetrically fixedly connected to the bottom of the mounting grooves 407. A wedge block 409 is fixedly connected between the end faces of the two second springs 408. The wedge block 409 mates with the side groove 307, with its inclined surface on the upper side. The support plate 403 and the locking block 406 are fixedly connected... A dust cover 410 is attached, located outside the first damper 404 and the first spring 405. When the support plate 304 rotates downward to a flat position, the lowering of the support plate 304 causes the locking block 406 to enter the bottom groove 306. After the locking block 406 enters the bottom groove 306, the upper inclined surface of the wedge block 409 contacts the inner wall of the bottom groove 306, causing the wedge block 409 to be pressed into the mounting groove 407. Simultaneously, the second spring 408 is compressed. After the locking block 406 is fully inserted into the bottom groove 306, the rebound force of the second spring 408 causes the wedge block 409 to pop out and lock into the side groove 307. The setting of block 409 in the side groove 307 can lock the support plate 304 and the locking block 406. After the crossbeam body 201 is installed, since the positioning rod 209 is fully inserted into the positioning hole 305, the crossbeam body 201 and the support plate 304 are in a close fit. Therefore, the support plates 304 on both sides provide support for the bottom sides of the crossbeam body 201. The pressure and vibration generated by the crossbeam body 201 after installation will be transmitted to the support plate 304. Since the support plate 304 and the locking block 406 are locked, the pressure and vibration on the support plate 304 will be transmitted to the first damper 404 and the first spring 405 through the locking block 406. The combined use of the damper 404 and the first spring 405 can play a role in buffering and shock absorption. That is, it can provide good buffering and support for the installation position of the beam body 201. While the pre-embedded threaded rod 6 of the beam body 201 and the column 1 are in a rigid connection to ensure stability, the pressure is distributed at the bottom of the beam body 201. The pressure-distributing part is in a soft connection for buffering and support, which can provide a certain deformation capacity for the assembly and fixing position of the beam body 201 and the column 1. This allows the building structure to undergo a certain displacement and deformation when affected by external forces, vibrations or earthquakes, better adapt to different environmental conditions, reduce the vibration response of the structure, and thus protect the safety of the building and people.

[0042] like Figure 8 and Figure 9As shown, a reinforcing plate 402 is symmetrically fixedly connected to the top of the support frame 401, and a first bracket 411 is fixedly connected to the top of the support frame 401. A first support rod 412 is rotatably connected to the inner surface of the first bracket 411, and a first support block 413 is fixedly connected to the outer surface of the first support rod 412. After the crossbeam body 201 is installed, the support frame 401 provides support for the pressure distribution position of the crossbeam body 201. The reinforcing plate 402 can provide reinforcement to the splicing weld position of the support frame 401, thereby improving the load-bearing capacity of the support frame 401.

[0043] like Figure 8 and Figure 9 As shown, a second bracket 414 is fixedly connected to the outer surface of the support frame 401. A second support rod 415 is rotatably connected to the inner surface of the second bracket 414. A second support block 416 is fixedly connected to the outer surface of the second support rod 415. A second damper 417 is fixedly connected between the first support block 413 and the second support block 416. A third spring 418 is sleeved on the outer surface of the second damper 417. The two end faces of the third spring 418 are fixedly connected to the first support block 413 and the second support block 416, respectively. While supporting the crossbeam body 201, the outer side of the support frame 401 is subjected to... The pressure is transmitted to the first support 411. Through the connection between the first support rod 412 and the first support block 413, the second damper 417 is in a movable relationship with the support frame 401. Through the connection between the second support rod 415 and the second support block 416, the second damper 417 is in a rotating relationship with the other side of the support frame 401. At this time, the second damper 417 and the third spring 418 work together to buffer and support the pressure on the outer side of the support frame 401, improve the stability of the support frame 401 structure, and thus improve the load-bearing strength of the crossbeam body 201.

[0044] like Figure 3 and Figure 4As shown, a second connecting seat 9 is fixedly connected to the outer surface of the column 1 away from the first connecting seat 301. A second connecting rod 10 is rotatably connected to the inner surface of the second connecting seat 9. A second rotating block 11 is fixedly connected to the outer surface of the second connecting rod 10. A second baffle 12 is fixedly connected to the outer surface of the second rotating block 11. The second baffle 12 is positioned to cooperate with the first baffle 7. Limiting holes 13 are symmetrically opened through the second baffle 12 on the outer surface of the first baffle 7. By using the second baffle 12 on the other side of the beam body 201, after the beam body 201 and the column 1 are assembled, the end face of the beam body 201 is spliced ​​with the first baffle 7 and the second baffle 12 to form a frame. The frame is located outside the installation position of the pre-embedded threaded rod 6. Subsequently, in conjunction with the installation structure on the upper side, it can protect the installation position of the pre-embedded threaded rod 6, preventing the pre-embedded threaded rod 6 and the nut 208 from being exposed to the outside for a long time and rusting and damage, thus improving the service life of the building structure.

[0045] In this invention, during the assembly and connection of prefabricated concrete frame nodes, the support plate 304 can rotate freely through the connection of the first connecting rod 302 and the first rotating block 303. When the support plate 304 rotates downward to a flat position, the locking block 406 will enter the bottom groove 306 after the support plate 304 is lowered. The upper inclined surface of the wedge block 409 will contact the inner wall of the bottom groove 306, causing the wedge block 409 to be pressed into the installation groove 407. After the locking block 406 is fully inserted into the bottom groove 306, the rebound force of the second spring 408 can cause the wedge block 409 to pop out and lock into the side groove 307. The setting of the wedge block 409 locking into the side groove 307 can lock the support plate 304 and the locking block 406 into a locked state. After the support plate 304 is rotated to a flat position, the crossbeam body 201 can be assembled. The crossbeam body 201 is hoisted onto the upper side of the two columns 1. The position of the crossbeam body 201 is aligned so that the splicing plates 203 on both sides are aligned with the positions of the columns 1. Then, the crossbeam body 201 is lowered to mate with the columns 1. Lowering the crossbeam body 201 allows the center rod 5 to be inserted into the center hole 205, and the pre-embedded threaded rod 6 to be inserted into the fastening hole 204. After mate assembly, the ring 206 and the positioning plate 207 are respectively placed on the outer sides of the center rod 5 and the pre-embedded threaded rod 6. Then, the nut 208 is tightened on the outer side of the pre-embedded threaded rod 6 to secure it, completing the assembly and fixation of the crossbeam body 201 and the columns 1. After assembly and fixation, the ring 206... The positioning plate 207 is clamped and fixed between the nut 208 and the splicing plate 203. During construction, the force on the pre-embedded threaded rod 6 and the nut 208 can be distributed through the ring 206 and the positioning plate 207, thereby preventing the nut 208 from loosening due to the force on a single pre-embedded threaded rod 6. This provides a good tightening and anti-loosening effect for the installation position of the nut 208, improving the stability of the assembly of the beam body 201 and the column 1. While the center rod 5 and the pre-embedded threaded rod 6 are being aligned and connected, the positions of the positioning rod 209 and the positioning hole 305 are also being aligned. After confirming that the positioning rod 209 and the positioning hole 305 are aligned and in a vertical position, the beam body 201 is moved down for assembly. The positioning rods 209 on both sides are aligned with the positioning hole 305. The use of hole 305 can calibrate and position the lateral tilt angle of the beam body 201, ensuring that the beam body 201 remains horizontal during assembly. This provides lateral reinforcement to the beam body 201, enhancing the overall structural strength of the prefabricated concrete frame. After the beam body 201 is installed, the pressure and vibration generated by it are transmitted to the support plate 304. The first damper 404 and the first spring 405 work together to buffer and reduce vibration, providing good support for the installation position of the beam body 201. While the pre-embedded threaded rod 6 of the beam body 201 and the column 1 ensures stability through a rigid connection,…The pressure is distributed at the bottom of the beam body 201. This pressure-distributing portion is a flexible connection providing buffer support, allowing for some deformation capacity at the assembly and fixing position of the beam body 201 and the column 1. After the beam body 201 is installed, the support frame 401 provides support for the pressure-distributing position. The second damper 417 and the third spring 418 work together to buffer the pressure on the outer, open area of ​​the support frame 401, improving the stability of the support frame 401 structure and thus increasing the load-bearing strength of the beam body 201. The end face of the beam body 201, together with the first baffle 7 and the second baffle 12, forms a frame. This frame is located outside the installation position of the embedded threaded rod 6. Subsequently, in conjunction with the upper installation structure, it protects the installation position of the embedded threaded rod 6, preventing the embedded threaded rod 6 and nut 208 from prolonged exposure to the outside and corrosion damage, thus extending the service life of the building structure.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
