Description

Technical Field

[0001] The utility model relates to the technical field of the connection between a prefabricated capping beam and a pier, in particular to an auxiliary device for connecting a prefabricated capping beam and a pier. Background Technique

[0002] A prefabricated capping beam is a precast component used in bridges, elevated roads or building structures. The connection between a prefabricated capping beam and a pier is one of the key technologies in the design and construction of prefabricated bridges, ensuring the overall stability and structural safety of the bridge. The choice of connection method directly affects the construction convenience, structural durability and seismic performance. The grouting sleeve connection uses pre-embedded grouting sleeves. The steel bars in the precast components are inserted into the sleeves, and then the sleeves are filled with grout. This connection method requires a high positioning accuracy of the steel bars, but can provide good structural continuity and strength.

[0003] During the bridge construction process, after the foundation is laid, piers will be built on the foundation. Steel bars are placed inside the piers. Plug-in holes are reserved at the bottom of the capping beam, and grouting holes are reserved on the side. When the plug-in holes are docked with the steel bars, the splicing is completed. However, due to the heavy capping beam and the high pier, during the docking process, inaccurate docking and insufficient docking accuracy will affect the installation efficiency and the project progress. And how to stably connect the auxiliary device for connecting the prefabricated capping beam and the pier to the pier is also the key.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0025] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] As Figures 1 - 6 shown, an auxiliary device for connecting a prefabricated capping beam and a pier includes: a first plug board 1, a first connecting plate 2 disposed on one side of the first plug board 1, the first connecting plate 2 being L-shaped, a pier 6 disposed between the first plug board 1 and the first connecting plate 2, a capping beam 5 disposed on the top of the pier 6, second plug boards 3 and second connecting plates 4 disposed on both sides of the capping beam 5, and a connecting component disposed between the first plug board 1 and the first connecting plate 2 and between the second plug boards 3 and the second connecting plates 4. The connecting component includes: a connecting block a 104, a connecting groove a 201, a connecting block b 303, and a connecting groove b 403. An auxiliary positioning component is disposed on one side of the first plug board 1 and one side of the second plug board 3. The auxiliary positioning component includes: an infrared receiver 102, a trapezoidal groove 103, a trapezoidal block 301, and an infrared emitter 302.

[0027] Among them, through the setting of the connecting component, the auxiliary device is installed in the accurate position by using the positioning ribs 601 and the threaded holes 502 to ensure the position of the auxiliary device in the vertical direction, and multiple bolts are used to connect the plug board and the connecting plate to ensure the horizontal position of the plug board and the connecting plate, which can improve the subsequent docking accuracy. Secondly, through the setting of the auxiliary positioning component, before the capping beam 5 and the pier 6 are docked, pre-docking is first performed. When it is determined that the infrared receiver 102 receives the signal of the infrared emitter 302 and the trapezoidal block 301 and the trapezoidal groove 103 are correctly docked during the descent, the docking of the capping beam 5 and the pier 6 can be determined, which can improve the docking accuracy and the installation efficiency at the same time.

[0028] Among them, a plurality of positioning holes a101 are formed at the bottom of the first plug board 1, two infrared receivers 102 are arranged on the upper surface of the first plug board 1, a trapezoidal groove 103 is formed at one end of the first plug board 1, two connecting blocks a104 are fixedly arranged on one side of the first plug board 1, and two connecting holes a105 are formed in each of the connecting blocks a104. A plurality of positioning holes b204 are formed at the bottom of the first connecting plate 2, a plurality of auxiliary grouting ports 205 are formed on one side of the first connecting plate 2, two connecting grooves a201 are formed on one side of the first connecting plate 2, the connecting grooves a201 are the same size as the connecting blocks a104, two connecting holes b202 are formed inside the first connecting plate 2, the connecting holes b202 communicate with the connecting grooves a201, and bolts a203 are arranged in the connecting holes b202. Before docking, first align the positioning holes a101 and the positioning holes b204 with the positioning bars 601, and at the same time place the connecting blocks a104 in the connecting grooves a201. After alignment, use the bolts a203 to pass through the connecting holes a105 and the connecting holes b202 to connect the first plug board 1 and the first connecting plate 2, and fix them with a plurality of bolts a203, so that the first plug board 1 and the first connecting plate 2 are in the same horizontal position, improving the docking accuracy of the trapezoidal block 301 and the trapezoidal groove 103. During pre-docking, the infrared receivers 102 receive the signals of the infrared transmitters 302, so that during pre-docking, the capping beam 5 is in the correct docking position.

[0029] Among them, one end of the second plug board 3 is provided with a trapezoidal block 301, two infrared emitters 302 are arranged on the lower surface of the second plug board 3, two connecting blocks b303 are fixedly arranged on one side of the second plug board 3, and two connecting holes c304 are respectively opened inside the connecting blocks b303. One end of the second connecting plate 4 is fixedly connected with a power supply 401, a light bulb 402 is fixedly arranged on one side of the second connecting plate 4, a radar 406 is arranged at the bottom of the second connecting plate 4, two connecting grooves b403 are opened on one side of the second connecting plate 4, and the connecting grooves b403 are the same size as the connecting blocks b303. Two connecting holes d404 are opened inside the second connecting plate 4, the connecting holes d404 communicate with the connecting grooves b403, bolts b405 are arranged inside the connecting holes d404. Threaded holes 502 are opened on both sides of the capping beam 5. L-shaped plates 407 are arranged on the tops of the second plug board 3 and the second connecting plate 4. Through holes 503 are opened inside the L-shaped plates 407, and the through holes 503 are the same size as the threaded holes 502. Bolts c408 are arranged inside the L-shaped plates 407. The bolts c408 penetrate through the through holes 503 and extend into the threaded holes 502. Before docking, first align the through holes 503 with the threaded holes 502, and then use the bolts c408 to pass through the through holes 503 and the threaded holes 502, so that the second plug board 3 and the second connecting plate 4 are respectively connected and fixed to the capping beam 5. After that, align the connecting holes c304 with the connecting holes d404, and use the bolts b405 to pass through the connecting holes c304 and the connecting holes d404 to connect the second plug board 3 and the second connecting plate 4, so that the second plug board 3 and the second connecting plate 4 are in the same horizontal position, which can improve the subsequent docking accuracy.

[0030] After installing the auxiliary device, when moving the capping beam 5, by observing the positions of the trapezoidal groove 103 and the trapezoidal block 301, the docking position of the capping beam 5 and the bridge pier 6 can be initially judged, and then the docking position is determined. The infrared emitter 302 emits a signal. When both infrared receivers 102 receive the signal, the capping beam can be slowly lowered. During the lowering process, the trapezoidal groove 103 and the trapezoidal block 301 are pre-docked. After the position is confirmed to be correct and the trapezoidal groove 103 and the trapezoidal block 301 are successfully docked, the capping beam 5 can be moved at a faster speed. After the capping beam 5 is moved to a certain height, the radar 406 transmits a signal to the light bulb 402, and the light bulb 402 emits a red light, and the movement of the capping beam 5 is stopped. At this time, grouting can be started. The cement enters from the auxiliary grouting port 205. Through the setting of the main grouting port of the kettle, the opening of the grouting port of the bridge pier 6 can be reduced, and the damage to the bridge pier 6 can be reduced.

[0031] A plurality of grouting ports 501 are arranged on the outer surface of the capping beam 5. A plurality of steel bars 603 are fixedly connected to the top of the bridge pier 6. A plurality of grouting pipes 602 are arranged on the top of the bridge pier 6. A plurality of positioning bars 601 are arranged on the top of the bridge pier 6. Grouting the grouting pipes 602 and the auxiliary grouting port 205 simultaneously can improve the grouting efficiency and also make the cement fill the entire space. When grouting, air can be discharged from the grouting ports 501, thereby reducing the air inside the bridge pier.

[0032] Working principle: Before docking, first align the positioning hole a101 and the positioning hole b204 with the positioning rib 601, and at the same time place the connecting block a104 in the connecting groove a201. After alignment, use the bolt a203 to pass through the connecting hole a105 and the connecting hole b202 to connect the first plugboard 1 and the first connecting plate 2, and fix them with multiple bolts a203, so that the first plugboard 1 and the first connecting plate 2 are in the same horizontal position, improving the docking accuracy of the trapezoidal block 301 and the trapezoidal groove 103. Then align the through hole 503 with the threaded hole 502, and then use the bolt c408 to pass through the through hole 503 and the threaded hole 502 to connect the second plugboard 3 and the second connecting plate 4 to the capping beam 5 respectively. After that, align the connecting hole c304 with the connecting hole d404, and use the bolt b405 to pass through the connecting hole c304 and the connecting hole d404 to connect the second plugboard 3 and the second connecting plate 4, so that the second plugboard 3 and the second connecting plate 4 are in the same horizontal position again, which can improve the subsequent docking accuracy. After installing the auxiliary device, start the pre-docking. Move the capping beam 5, and by observing the positions of the trapezoidal groove 103 and the trapezoidal block 301, the docking position of the capping beam 5 and the pier 6 can be initially judged. Then determine the docking position. During the pre-docking, the infrared receiver 102 receives the signal from the infrared transmitter 302, so that during the pre-docking, the capping beam 5 is in the correct docking position. When both infrared receivers 102 receive the signal, the capping beam can be slowly lowered. During the lowering process, the trapezoidal groove 103 and the trapezoidal block 301 are pre-docked. After the position is confirmed to be correct and the trapezoidal groove 103 and the trapezoidal block 301 are successfully docked, the capping beam 5 can be moved at a faster speed. After the capping beam 5 is moved to a certain height, the radar 406 transmits a signal to the bulb 402, and the bulb 402 emits a red light, and the movement of the capping beam 5 is stopped. At this time, grouting can be started. The cement enters from the auxiliary grouting port 205. The setting of the auxiliary grouting port 205 can reduce the opening of the grouting port of the pier 6 and reduce the damage to the pier 6. The simultaneous grouting of the grouting pipe 602 and the auxiliary grouting port 205 can improve the grouting efficiency and also make the cement fill the entire space. During grouting, the air can be discharged from the grouting port 501, thereby reducing the air inside the pier. After the docking is completed, remove the bolt b405 and the bolt c408, separate the second plugboard 3 and the second connecting plate 4, and then remove the bolt a203 to separate the first plugboard 1 and the first connecting plate 2.
