Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a quick assembly and disassembly structure for bridge pier support template. Background Technology

[0002] During the construction of bridge piers, support and formwork are required. Their main function is to ensure the stability and geometric shaping of the structure during concrete pouring. The formwork system bears the lateral pressure, self-weight, and construction loads of the newly poured concrete, preventing deformation or collapse. The support structure, through components such as columns, beams, tie rods, and diagonal braces, forms a stable force-bearing system, effectively transferring loads to the foundation and avoiding uneven settlement. Simultaneously, the support ensures the verticality, cross-sectional dimensions, and surface flatness of the piers, meeting design accuracy requirements. Furthermore, proper support can improve construction safety, reduce accident risks, and protect the safety of workers. The support system continues to function until the concrete reaches sufficient strength, ensuring the structural integrity and durability, making it a key technical aspect for the successful formation of bridge piers.

[0003] During the construction of bridge piers, four support beams are usually set around the pier formwork. These support beams form an integrated structure through a firm connection with the formwork and with each other, which effectively ensures the structural stability during the pouring process. However, although this connection method enhances rigidity and safety, the disassembly process is complicated and time-consuming, which affects the construction efficiency and is not conducive to the rapid turnover and reuse of the formwork and support system.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Please see Figures 1 to 5 This utility model provides a quick-assembly and disassembly structure for bridge pier support formwork, comprising: a formwork body 1; two sets of first support beams 2 and second support beams 3 symmetrically arranged vertically, the first support beams 2 and second support beams 3 being disposed on the outside of the formwork body 1; a disassembly and assembly assembly, which is installed on the first support beams 2 and second support beams 3 for connecting the first support beams 2 and second support beams 3; and a connecting assembly, which is installed on the first support beams 2 and second support beams 3 for installing the formwork body 1 onto the first support beams 2 and second support beams 3.

[0017] The above scheme is adopted as follows: In the pier support operation, the workers first install the template body 1, and then place two first support beams 2 and two second support beams 3 on the outside of the template body 1. The first support beams 2 and the second support beams 3 are connected to each other by the disassembly and assembly components, and the template body 1 is fixed to the first support beams 2 and the second support beams 3 by the connecting components, thereby completing the construction of the template body 1. The combined use of the disassembly and assembly components and the connecting components forms a combined support structure, which facilitates the disassembly and installation of the template.

[0018] Furthermore, the assembly and disassembly assembly includes: a first mounting groove 4 formed on the first support beam 2 and the second support beam 3; and second mounting grooves 5 formed on both sides of the template body 1, arranged symmetrically at the top and bottom; and a first connecting plate 6 inserted into the first mounting groove 4 and the second mounting groove 5.

[0019] Furthermore, two symmetrically arranged insert plates 7 are fixedly connected to the first connecting plate 6, and brackets 8 are sleeved on the first support beam 2 and the second support beam 3; a sleeve plate 9 that cooperates with the insert plates 7 is fixed inside the bracket 8.

[0020] Furthermore, each of the brackets 8 is provided with a first slide rail 10; a first slider 11 is slidably connected in the first slide rail 10; a fixing rod 12 is fixedly connected to one side of the first slider 11, and one end of the fixing rod 12 extends to the first support beam 2 and the second support beam 3.

[0021] Furthermore, a positioning groove 13 is provided on the other side of the first slider 11; a first fixing block 14 is inserted into the positioning groove 13, and a threaded rod 15 is rotatably connected to one side of the first fixing block 14, and a bearing plate 16 is provided between the threaded rods 15; one side of the bearing plate 16 is attached to the two brackets 8; a threaded sleeve 17 that cooperates with the threaded rod 15 is rotatably connected to the bearing plate 16, and four symmetrically arranged bolts 18 are threadedly connected to the bearing plate 16, and one end of each bolt 18 extends into the bracket 8.

[0022] Using the above scheme: In use, the first connecting plate 6 is inserted into the first mounting groove 4 in the first support beam 2 and the second support beam 3. At this time, one side of the first connecting plate 6 will be inserted into the second mounting groove 5 of the template body 1. Then, the bracket 8 is sleeved on the first support beam 2 and the second support beam 3. At this time, the sleeve plate 9 on the bracket 8 will be inserted into the insert plate 7 of the first connecting plate 6. The bracket 8 is used to connect the four corners formed by the first support beam 2, the second support beam 3 and the first connecting plate 6. After the bracket 8 is installed, the first positioning block 19 is inserted into the positioning groove of the first slider 11. In step 13, one side of the bearing plate 16 will be attached to the two symmetrical brackets 8, and the bolts 18 will be screwed into the bearing plate 16 and the brackets 8 to fix the brackets 8 in the current position. Then, the threaded sleeve 17 will be rotated so that the two threaded rods 15 will drive the first positioning blocks 19 on them to move away from each other. The first positioning blocks 19 will drive the first slider 11 on them to move in the first slide rail 10. After the first slider 11 moves to the preset position, the fixing rod 12 on it will be inserted into the first connecting plate 6 to fix the first connecting plate 6, thus forming an integral combination structure.

[0023] It should be noted that: First, if dismantling is required, the above principle can be reversed. Second, the number of bearing plates 16 and bolts 18 can be increased according to actual needs, thereby increasing the stability of the connection between the two brackets 8.

[0024] Furthermore, the connecting component includes: a second slide rail 21 formed on the template body 1 and the first support beam 2 and the second support beam 3, wherein a first positioning block 19 and a second positioning block 20 are slidably connected in the second slide rail 21.

[0025] Furthermore, one end of the first positioning block 19, which is threadedly connected to the adjusting screw 22, extends into the second positioning block 20.

[0026] Using the above scheme: In use, the first positioning block 19 and the second positioning block 20 are moved in the second slide rail 21 by the staff. After the first positioning block 19 and the second positioning block 20 are moved to the preset position, they will be aligned with each other. Then, by inserting the adjusting screw 22 into the first positioning block 19 and the second positioning block 20, the connection and fixation of the first positioning block 19 and the second positioning block 20 are realized. This process indirectly installs the template body 1 onto the first support beam 2 and the second support beam 3, forming a secondary connection and fixation.

[0027] The working principle of this utility model: In the pier support operation, the workers first install the formwork body 1. Then, two first support beams 2 and two second support beams 3 are placed on the outside of the formwork body 1. The first connecting plate 6 is inserted into the first mounting groove 4 in the first support beams 2 and 3. At this time, one side of the first connecting plate 6 is inserted into the second mounting groove 5 of the formwork body 1. Next, the bracket 8 is fitted onto the first support beams 2 and 3. At this time, the sleeve plate 9 on the bracket 8 is inserted into the insert plate 7 of the first connecting plate 6. The bracket 8 is used to connect the four corners formed by the first support beams 2, 3, and the first connecting plate 6. After the bracket 8 is installed, the first positioning block 19 is inserted into the positioning groove 13 of the first slider 11. At this time, one side of the bearing plate 16 will fit against the two symmetrical brackets 8. The bolts 18 are screwed into the bearing plate 16 and the brackets 8 to fix the brackets 8 in the current position. Next, rotate the threaded sleeve 17 to move the two threaded rods 15 away from each other, and the first positioning block 19 on the first positioning block 19 will move the first slider 11 on it within the first slide rail 10. After the first slider 11 moves to the preset position, the fixing rod 12 on it will be inserted into the first connecting plate 6 to fix the first connecting plate 6, thus forming an integral combination structure. The worker pushes the first positioning block 19 and the second positioning block 20 to move in the second slide rail 21. After the first positioning block 19 and the second positioning block 20 move to the preset position, they will be aligned with each other. Then, by inserting the adjusting screw 22 into the first positioning block 19 and the second positioning block 20, the connection and fixation of the first positioning block 19 and the second positioning block 20 are realized. This process indirectly installs the template body 1 onto the first support beam 2 and the second support beam 3, forming a secondary connection and fixation.
