Description

Technical Field

[0001] This invention relates to the field of continuous beam bridge construction technology, specifically a connection device for the construction of concrete continuous beam bridges. Background Technology

[0002] A continuous concrete beam bridge is a bridge structure built using concrete as the main building material. It consists of multiple spans of beams connected end to end in a continuous manner, spanning multiple piers. The beams are usually made of reinforced concrete or prestressed concrete and are stably supported on the piers and abutments. When using methods such as segmented construction or span-by-span construction, temporary connections are required between adjacent beams before the final connection construction is completed. This is to ensure the integrity and stability of the structure during construction and to facilitate subsequent construction operations.

[0003] In existing methods for temporary connection of adjacent beams, mounting holes are typically made on the adjacent surfaces of the beams to accommodate bolts. The connection is then established by using a connecting plate with bolts. However, in order to ensure the stability of the connection, a large number of bolts are used to fix the connecting plate. This makes the entire connection operation cumbersome and subsequent disassembly very troublesome. Furthermore, the large number of mounting holes made to facilitate bolt fixing can affect the structure of the beam, leading to a decrease in the overall strength and stability of the beam. Summary of the Invention

[0004] The purpose of this invention is to provide a connection device for the construction of a continuous concrete beam bridge, in order to solve the problems of existing temporary connection devices being cumbersome to operate and inconvenient to dismantle later, and the installation holes affecting the strength and stability of the beam.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connecting device for the construction of a continuous concrete beam bridge, comprising a beam body, a hollow column embedded part, and a side plate. The number of beam bodies is two, the hollow column embedded part is fixedly connected to the inside of the beam body, the inner sidewalls of the two beam bodies are provided with connecting plates, and an I-beam connecting block is provided between the two connecting plates.

[0006] The side plates are located on the front and rear sides of the two beams, and the inner walls of the two side plates are fixedly connected with rods. The top of the two connecting plates is provided with a top plate.

[0007] It can facilitate quick and easy connection and fixation of adjacent beams, making operation convenient and subsequent dismantling easy. At the same time, it eliminates the need to drill installation holes on the beams for connection, ensuring the strength and stability of the beams. Additionally, it can use the side plates to assist in limiting the connection of the connected beams, reducing the connection pressure of the I-beam connectors and enhancing the overall stability of the structure.

[0008] Preferably, the hollow column embedded parts are evenly distributed from front to back, and the inner sidewalls of the two connecting plates are provided with connecting grooves on the front and back sides. The I-shaped connecting block is inserted into the inner cavity of the connecting groove. The inner sidewalls of the connecting plates are screwed with connecting bolts, which are evenly distributed from front to back and are screwed to the hollow column embedded parts.

[0009] The connecting plate can be installed quickly and easily by using connecting bolts and hollow column embedded parts, which facilitates subsequent operations.

[0010] Preferably, the outer wall of the hollow column embedded part is provided with a reinforcing ring groove, and the reinforcing ring groove is evenly distributed.

[0011] By setting up reinforcing ring grooves, the fixing effect of hollow column embedded parts inside the beam can be improved, thereby improving the fixing effect of subsequent connections.

[0012] Preferably, the inner sidewall of the reinforcing ring groove is provided with openings on both sides, the openings are connected to the inner cavity of the hollow column embedded part, and the outer sidewall of the connecting plate is uniformly provided with teeth.

[0013] By setting orifices, concrete can easily enter the hollow column embedded parts during beam pouring, allowing the hollow column embedded parts to integrate with the beam, thereby enhancing the subsequent fixing effect. By setting serrations, the friction and mechanical engagement between the connecting plate and the beam can be increased, effectively limiting the relative displacement of the connecting plate and the beam in the vertical direction, so that they can maintain a relatively fixed positional relationship under load, thereby improving the fixing effect. At the same time, it can withstand greater loads without loosening or falling off, improving the stability and reliability of the connection, and further enhancing the fixing effect.

[0014] Preferably, the ends of the front and rear rods pass through the front and rear I-beam connecting blocks respectively, and the rods are movably connected to the I-beam connecting blocks, and the top plate is fixedly connected to the connecting plate by screws.

[0015] The installation and removal of the side plates are facilitated by the setting of the rod body, which in turn limits the beam body and limits and fixes the I-beam connecting block.

[0016] Preferably, a limiting plate is fixedly connected to the front and rear sides of the bottom of the top plate, the limiting plate is located between the two I-beam connecting blocks, and a limiting vertical groove is formed at the bottom of the limiting plate.

[0017] The locking block is fixed by using a limiting plate and a limiting vertical groove, thereby fixing and limiting the rod body, while also facilitating the assembly and disassembly of the whole.

[0018] Preferably, a locking block is fixedly connected to the end of the rod, and the locking block engages with the limiting vertical groove.

[0019] The rod can be easily fixed by setting a locking block.

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

[0021] 1. This application uses hollow column embedded parts and connecting bolts to easily fix the connecting plate without the need to open installation holes for connection on the beam, thus ensuring the strength and stability of the beam. The connecting plate, together with the I-beam connecting block and connecting groove, temporarily connects and fixes adjacent beams, which is very convenient and quick. It is easy to operate and also very convenient to dismantle later. The hollow column embedded parts, together with the reinforcing ring groove and the hole, improve the fixing effect of the hollow column embedded parts inside the beam, thereby improving the fixing effect of the subsequent connection.

[0022] 2. This application uses side plates and rods to assist in limiting the beam after it has been temporarily connected and fixed, thereby reducing the connection pressure of the I-beam connecting blocks and enhancing the overall stability of the structure. The rods are fixed and limited by limiting plates, limiting vertical slots, locking blocks and top plates, which facilitates the assembly and disassembly of the whole structure.

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.

[0032] Example: Figures 1-7 As shown, the present invention provides a technical solution for a connection device used in the construction of a continuous concrete beam bridge.

[0033] Please refer to this carefully. Figures 1-7 The system includes two beams 100, hollow column embedded parts 200, and side plates 300. The hollow column embedded parts 200 are fixedly connected inside the beams 100. Connecting plates 210 are provided on the inner walls of the two beams 100, and I-beam connecting blocks 211 are provided between the two connecting plates 210. The hollow column embedded parts 200 are evenly distributed from front to back. Connecting grooves 220 are opened on the front and rear sides of the inner walls of the two connecting plates 210. The I-beam connecting blocks 211 are inserted into the inner cavities of the connecting grooves 220. Connecting bolts 221 are screwed onto the inner walls of the connecting plates 210. The connecting bolts 221 are evenly distributed from front to back and are screwed onto the hollow column embedded parts 200. Reinforcing ring grooves 230 are opened on the outer walls of the hollow column embedded parts 200 and are evenly distributed. The inner sidewall of the 0 has openings 240 on both sides, which are connected to the inner cavity of the hollow column embedded part 200. The outer sidewall of the connecting plate 210 is evenly provided with teeth. The connecting device for the construction of this concrete continuous beam bridge can easily fix the connecting plate 210 by using the hollow column embedded part 200 and connecting bolts 221. There is no need to open the installation holes for connection on the beam 100, which ensures the strength and stability of the beam 100. The connecting plate 210, together with the I-beam connecting block 211 and the connecting groove 220, temporarily connects and fixes the adjacent beams 100, which is very convenient and quick. It is easy to operate and easy to dismantle later. The hollow column embedded part 200, together with the reinforcing ring groove 230 and the openings 240, improves the fixing effect of the hollow column embedded part 200 inside the beam 100, thereby improving the fixing effect of the subsequent connection.

[0034] Please refer to this carefully. Figures 1-4Side plates 300 are located on the front and rear sides of the two beams 100. Rods 310 are fixedly connected to the inner walls of the two side plates 300. A top plate 311 is provided on the top of the two connecting plates 210. The ends of the rods 310 on the front and rear sides respectively pass through the I-beam connecting blocks 211 on the front and rear sides, and the rods 310 and I-beam connecting blocks 211 are movably connected. The top plate 311 is fixedly connected to the connecting plates 210 by screws. Limiting plates 320 are fixedly connected to the front and rear sides of the bottom of the top plate 311. The limiting plates 320 are located between the two I-beam connecting blocks 211, and the bottom of the limiting plates 320 has an opening... The limit groove 321 is provided, and the end of the rod 310 is fixedly connected to a locking block 330. The locking block 330 engages with the limit groove 321. This connection device for the construction of a concrete continuous beam bridge uses the side plate 300 in conjunction with the rod 310 to assist in limiting the beam 100 after it has been temporarily connected and fixed, thereby reducing the connection pressure on the I-beam connecting block 211 and enhancing the overall stability of the structure. The rod 310 is fixed and limited by the limit plate 320, the limit groove 321, the locking block 330 and the top plate 311, which facilitates the assembly and disassembly of the whole structure.

[0035] In use, when temporary connection of two adjacent beams 100 is required during construction, the connecting plate 210 is placed at the hollow column embedded part 200 of the beam 100, and the connecting bolt 221 is screwed into the hollow column embedded part 200 to install and fix the connecting plate 210. Similarly, the connecting plate 210 on the other beam 100 is fixed. Then, the I-beam connecting block 211 is inserted into the connecting groove 220 on the two connecting plates 210 to complete the temporary connection and fixation of the two beams 100. Finally, the rods 310 on the front and rear side plates 300 are inserted into the corresponding I-beam connecting blocks. In step 211, the top plate 311 is placed on top of the two connecting plates 210. During placement, the locking block 330 on the rod 310 enters the limiting vertical groove 321 on the limiting plate 320, thereby limiting and fixing the rod 310. The rod 310 fixes the side plate 300 and the I-beam connecting block 211. The side plates 300 on both sides provide auxiliary limiting for the beam 100. Then, the top plate 311 is fixed to the connecting plate 210 with screws. When disassembly is required, the top plate 311 is removed, the rod 310 is pulled out, the I-beam connecting block 211 is removed, and then the connecting plate 210 is removed.

[0036] It should be noted that the hollow column embedded part 200 mentioned in this application is set in the casting mold when the beam 100 is poured. It is integrally formed with the beam 100 as the concrete is poured. This is a common method for the installation of existing embedded parts, so it will not be described in detail.
