Description

Technical Field

[0001] This utility model relates to the field of concrete pipe construction technology, specifically to a connection structure for concrete pipes. Background Technology

[0002] For concrete pipes, the pipe ends are mainly connected using spigot and socket, flat end, and tongue and groove joints. When the pipeline pressure is high or the geological conditions are poor, welding or other methods are needed to connect and fix the pipes to prevent them from becoming disconnected, settling, or leaking. However, for pipelines in underwater or humid environments, welding is difficult and dangerous, and the quality of the work is hard to guarantee and control.

[0003] An existing application (application number 202411173646.X) discloses a concrete pipe connection structure and method, comprising pipes, anchors, and prestressed steel strands. The anchors are positioned opposite each other on the outer walls of the two pipes to be connected and have tensioning channels. The tensioning channels extend parallel to the pipe axis. The prestressed steel strands pass through the two tensioning channels, causing the anchors to abut against each other to achieve the pipe connection. The anchors include an extended portion and a tensioning element, which includes embedded parts and connectors, wherein the embedded parts are pre-embedded in the pipes. This concrete pipe connection structure has the following drawbacks: 1) The embedded parts are pre-embedded in the concrete pipes, resulting in poor structural strength. Multiple embedded parts are required to fix the extended portion to the pipes to form connection points, making construction complex; 2) The overall connection strength is difficult to guarantee, making construction inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a concrete pipe docking structure that is simple to construct, has good structural strength, and high overall connection strength.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A concrete pipe docking structure includes two opposing concrete pipes connected by a connecting mechanism. The connecting mechanism includes two anchoring components respectively disposed on the two concrete pipes, and a connecting component connecting the two anchoring components. Each anchoring component includes an anchor box and a tension seat. The anchor box is embedded in the side wall of the concrete pipe. The outer wall of the anchor box is provided with a socket. The tension seat is provided with a socket plate, which is inserted into the anchor box through the socket. The socket plate is provided with a limiting block. The tension seat is fixed to the outer side of the outer wall by fasteners, and the limiting block abuts against the inner side of the outer wall. The connecting component connects the tension seats of the two anchoring components.

[0007] As a further improvement to the above technical solution:

[0008] The anchoring assembly also includes a retaining plate, which is inserted into the anchoring box through the socket and abuts against the side of the socket plate away from the limiting block.

[0009] The clamping plate is fixed to the tension seat by a locking fastener.

[0010] The locking device is a locking bolt.

[0011] The tension support includes a tension plate and a fixing plate, which are vertically fixed. The socket plate is fixedly connected to the tension plate, and the fixing plate is fixed to the outer side of the outer wall by fasteners. The connecting assembly is connected between the tension plates of the two anchoring assemblies.

[0012] The tension plate and the fixing plate are connected in an L-shape, and a stiffening plate is provided between the two sides of the tension plate and the fixing plate.

[0013] The socket plate and the tension plate are located on the same plane.

[0014] The connecting assembly includes a screw and nuts. The two ends of the screw are respectively inserted into the corresponding tension seats and clamped to the tension seats by at least two nuts.

[0015] The anchor box is equipped with a reinforcing rod on its outer side.

[0016] A sealing component is provided at the joint of the two concrete pipes.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model discloses a butt joint structure for concrete pipes. During installation, the socket plate on the tension seat is inserted through the socket into the anchor box (pre-embedded in the side wall of the concrete pipe), so that the limiting block is located on the inner side of the outer wall. Then, the tension seat is fixed to the outer side of the outer wall (outer periphery of the concrete pipe) using fasteners, thus anchoring the anchoring component to the concrete pipe. Finally, the tension seats of the two anchoring components are connected by a connecting component, allowing the two concrete pipes to be butt jointed. This butt joint structure for concrete pipes has two advantages. First, by using the anchoring component, mainly composed of the anchor box and the tension seat, as the connection fulcrum, a pair of anchoring components are installed on each of the two concrete pipes, and then connected by a connecting mechanism. They can be installed in pairs sequentially, making construction simple and providing good structural strength. Second, the overall connection strength is high, and construction is convenient.

[0029] Figures 1 to 4 This invention illustrates an embodiment of the concrete pipe docking structure. The docking structure includes two opposing concrete pipes 1 connected by a connecting mechanism 2. The connecting mechanism 2 includes two anchoring components 3 respectively disposed on the two concrete pipes 1, and a connecting component 4 connected between the two anchoring components 3. Each anchoring component 3 includes an anchor box 31 and a tension seat 32. The anchor box 31 is embedded in the side wall of the concrete pipe 1. A socket 5 is provided on the outer wall 311 of the anchor box 31. A socket plate 33 is provided on the tension seat 32. The socket plate 33 passes through the socket 5 and is inserted into the anchor box 31. A limiting block 331 is provided on the socket plate 33. The tension seat 32 is fixed to the outer side of the outer wall 311 by fasteners 6. The limiting block 331 abuts against the inner side of the outer wall 311. The connecting component 4 is connected between the tension seats 32 of the two anchoring components 3.

[0030] During installation, the socket plate 33 on the tension seat 32 is inserted through the socket 5 into the anchor box 31 (pre-embedded in the side wall of the concrete pipe 1), so that the limiting block 331 is located inside the outer wall 311. Then, the tension seat 32 is fixed to the outer side of the outer wall 311 (outer periphery of the concrete pipe 1) by fasteners 6, thus anchoring the anchor component 3 to the concrete pipe 1. Then, the tension seats 32 of the two anchor components 3 are connected by the connecting component 4, so that the two concrete pipes 1 are joined together. This joint structure of the concrete pipes has two advantages. First, the anchor component 3, mainly composed of the anchor box 31 and the tension seat 32, serves as the connection fulcrum. A pair of anchor components 3 are installed on each of the two concrete pipes 1, and then a connecting mechanism 2 is connected. They can be installed in pairs in sequence, which is simple to operate and has good structural strength. Second, the overall connection strength is high and the construction is convenient.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the anchoring assembly 3 further includes a clamping plate 34, which is inserted into the anchoring box 31 through the socket 5 and abuts against the side of the socket plate 33 away from the limiting block 331. The side of the socket plate 33 away from the limiting block 331 is clamped by the clamping plate 34, further improving the strength of the anchoring assembly 3.

[0032] Furthermore, such as Figure 2 As shown, in this embodiment, the abutment plate 34 is fixed to the tension seat 32 by the locking fastener 7. This makes the abutment plate 34 and the tension seat 32 a single unit, resulting in higher strength.

[0033] Furthermore, in this embodiment, the locking element 7 is a locking bolt. The locking element 7 is located outside the anchor box 31.

[0034] Further, in this embodiment, the tension seat 32 includes a tension plate 321 and a fixing plate 322. The tension plate 321 and the fixing plate 322 are vertically fixed. The socket plate 33 is fixedly connected to the tension plate 321. The fixing plate 322 is fixed to the outside of the outer wall 311 by fasteners 6. The connecting assembly 4 is connected between the tension plates 321 of the two anchoring assemblies 3. Preferably, the tension plate 321 and the fixing plate 322 are steel plates welded together. The fasteners 6 are fastening bolts. The fixing plate 322 and the outer wall 311 are fixed by multiple fasteners 6. Preferably, the end of the fixing plate 322 away from the tension plate 321 extends to the outside of the anchoring box 31 and abuts against the outer circumferential surface of the concrete pipe 1.

[0035] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the tension plate 321 and the fixing plate 322 are connected in an L-shape, and a stiffening plate 323 is provided between the two sides of the tension plate 321 and the fixing plate 322. Preferably, the stiffening plate 323 is a steel plate, and the tension plate 321 and the fixing plate 322 are welded to the stiffening plate 323.

[0036] Furthermore, in this embodiment, the socket plate 33 and the tension plate 321 are located on the same plane. Preferably, both the socket plate 33 and the tension plate 321 are steel plates welded together.

[0037] Furthermore, in this embodiment, the connecting component 4 includes a screw 41 and a nut 42. Both ends of the screw 41 pass through corresponding tension seats 32 and are clamped to the tension seats 32 by at least two nuts 42. Specifically, both ends of the screw 41 pass through corresponding tension plates 321 and are clamped to the tension seats 32 by at least two nuts 42, and the screw 41 passes between the stiffening plates 323 on both sides of the tension plate 321.

[0038] Furthermore, such as Figure 3 As shown, in this embodiment, a reinforcing rod 8 is provided on the outer side of the anchor box 31 to improve the pre-embedded strength. Preferably, the anchor box 31 is square, with its outer wall 311 facing the outer periphery of the concrete pipe 1, and multiple reinforcing rods 8 are provided on each of the four sides of the anchor box 31. By embedding the reinforcing rods 8 in the side wall of the concrete pipe 1, the overall strength is improved. Preferably, the reinforcing rod 8 is a threaded rod.

[0039] Furthermore, in this embodiment, a sealing component 9 is provided at the joint of the two concrete pipes 1 to improve the sealing performance of the connection between the two concrete pipes 1.
