[0001] The utility model relates to the technical field of culverts, in particular to a joint protection mechanism for building concrete culverts. Background Technique
[0002] A culvert refers to a culvert whose body is built with reinforced concrete box-shaped pipe sections. Generally made of reinforced concrete, the culvert can ensure the smooth flow of water in the channel, avoid water flow blockage caused by obstacles, and cause disasters such as floods. It has the advantages of being firm, durable, and reusable, and can be used in roads, subways, bridges and other construction projects.
[0003] At present, due to the large area of construction projects, multiple culverts need to be spliced together during actual use. And multiple culverts are directly connected by bolts. Therefore, gaps will remain at the connection parts of the culverts, resulting in poor sealing performance during the connection of the culverts. Therefore, moisture in the external soil is likely to penetrate into the interior of the culvert through the gaps, resulting in the occurrence of dripping and leaking. For this reason, we propose a joint protection mechanism for building concrete culverts to solve the above problems. Content of the Utility Model

A protection frame is distributed on one side where the two groups of culvert bodies are close to each other. And second connection blocks are symmetrically connected to the side of the protection frame. And through holes are respectively opened inside the second connection blocks. Connecting plates are symmetrically distributed at the upper and lower ends of the through holes. And threaded grooves are respectively opened inside the connecting plates. Threaded rods are respectively inserted into the threaded grooves. And the bottom ends of the threaded rods are connected to the inner walls of the through holes through bearings. There are two groups of limiting rods on the sides where the connecting plates are away from each other. And the limiting rods are respectively inserted into the first connection blocks. The first connection blocks are arranged in an L-shaped structure. And the first connection blocks are connected to the side positions of the fixed plates.
[0007] Preferably, grooves are evenly opened at the bottom ends of the fixed plates. And balls are installed inside the grooves.
[0008] Preferably, sealing blocks are symmetrically connected to both ends of the protection frame. And the sealing blocks are respectively inserted into the sealing grooves. The sealing grooves are opened inside the fixed plates.
[0009] Preferably, the top end of the threaded rod extends above the second connecting block and is connected with a rotating block, and rubber strips are uniformly distributed on the outer surface of the rotating block.
[0010] Preferably, vertical rods are symmetrically connected inside the slot, and holes are formed at positions corresponding to the vertical rods inside the connecting plate.
[0011] Preferably, rubber rings are sleeved on the outer side of the limiting rod at equal intervals, a limiting groove adapted to the limiting rod is formed inside the first connecting block, and the inner wall of the limiting groove and the outer wall of the rubber ring are closely attached.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0022] Refer to Figures 1-4 , a joint protection mechanism for a building concrete box culvert, including a box culvert body 1. There are two groups of box culvert bodies 1 in total, and lifting lugs 2 are evenly connected above the two groups of box culvert bodies 1. Fixed plates 3 are symmetrically connected to both ends of the two groups of box culvert bodies 1. Protection frames 5 are distributed on the sides of the two groups of box culvert bodies 1 close to each other, and second connecting blocks 16 are symmetrically connected to the sides of the protection frames 5. And holes 8 are respectively opened inside the second connecting blocks 16. Connecting plates 9 are symmetrically distributed at the upper and lower ends of the holes 8, and threaded grooves are opened inside the connecting plates 9. Threaded rods 10 are inserted into the threaded grooves, and the bottom ends of the threaded rods 10 are connected to the inner walls of the holes 8 through bearings. External threads with opposite directions are opened on the outer walls of the upper and lower ends of the threaded rods 10, which are not shown in the figure. Therefore, when the threaded rods 10 rotate, the opposite movement of the two threaded rods 10 can be driven. There are two groups of limiting rods 12 on the sides of the connecting plates 9 away from each other, and the limiting rods 12 are all inserted into the first connecting blocks 7. The first connecting blocks 7 are set in an L-shaped structure, and the first connecting blocks 7 are connected to the side positions of the fixed plates 3. The L-shaped first connecting blocks 7 can facilitate the connection operation with the fixed plates 3.
[0023] Furthermore, referring to Figure 2 it can be known that grooves are evenly opened at the bottom ends of the fixed plates 3, and balls 15 are installed inside the grooves. Through the mutual cooperation of the grooves and the balls 15, it is convenient for the staff to translate the box culvert body 1 during the assembly process, thereby effectively improving the convenience during the use of this device.
[0024] Furthermore, referring to Figure 3 it can be known that sealing blocks 6 are symmetrically connected to both ends of the protection frames 5, and the sealing blocks 6 are all inserted into the sealing grooves 4. The sealing grooves 4 are opened inside the fixed plates 3. When the box culvert bodies 1 are spliced, the staff can place the protection frames 5 between the two groups of box culvert bodies 1. And through the opening of the sealing blocks 6 and the sealing grooves 4, the positioning operation of the protection frames 5 can be realized.
[0025] Furthermore, referring toFigure 3 and Figure 4 It can be known that the top end of the threaded rod 10 extends above the second connecting block 16 and is connected with a rotating block 11, and rubber strips are evenly distributed on the outer surface of the rotating block 11. Through the arrangement of the rotating block 11 and the rubber strips, the convenience of the staff rotating the threaded rod 10 can be improved.
[0026] Furthermore, referring to Figure 4 It can be known that vertical rods 14 are symmetrically connected inside the slot 8, and holes are provided at positions corresponding to the vertical rods 14 inside the connecting plate 9. Through the arrangement of the holes and the vertical rods 14, the guiding operation of the two groups of connecting plates 9 can be realized, thereby effectively ensuring the stability of the connecting plate 9 when it moves under force.
[0027] Furthermore, referring to Figure 4 It can be known that rubber rings 13 are equidistantly sleeved on the outer side of the limiting rod 12, a limiting groove adapted to the limiting rod 12 is provided inside the first connecting block 7, and the inner wall of the limiting groove and the outer wall of the rubber ring 13 are closely attached. Through the arrangement of multiple groups of rubber rings 13, the tightness of the limiting rod 12 when it is engaged in the limiting groove of the first connecting block 7 can be effectively ensured, and thus the reliability during the connection process of the fixing plate 3 and the protective frame 5 can be effectively ensured.
[0028] Furthermore, referring to Figure 1 and Figure 2 It can be known that the cross-section of the sealing block 6 and the sealing groove 4 is set as a loop structure, and the outer wall of the sealing block 6 and the inner wall of the sealing groove 4 are closely attached. Through the sealing groove 4 and the sealing block 6 set in the loop structure, the gap during the connection between the protective frame 5 and the fixing plate 3 can be reduced, thereby further improving the sealing performance of the protective frame 5 during the protection of the joint seam.
[0029] Working principle: When the present utility model is in use, the staff can first transfer the device to a suitable area, and then insert the sealing block 6 connected to the side of the protective frame 5 into the inside of the sealing groove 4. Then the staff can push another culvert body 1 to the other side of the protective frame 5, so that the sealing block 6 connected to the other side of the protective frame 5 is inserted into the fixing plate 3 distributed on the outer side of the other culvert body 1. At this time, the staff can rotate the rotating block 11 in sequence, thereby driving the simultaneous rotation of the threaded rod 10, so that the two groups of connecting plates 9 move towards each other inside the slot 8 under force. At this time, the limiting rod 12 connected to the side of the connecting plate 9 is engaged into the limiting groove provided inside the first connecting block 7 to realize the connection between the first connecting block 7 and the second connecting block 16, that is, to realize the installation operation of the protective frame 5. Through the arrangement of the protective frame 5, the protection of the joint seam of the culvert body 1 can be realized. Then the staff can use bolts to assemble the culvert bodies 1. The above is the entire working principle of the present utility model.
