Description

Technical Field

[0001] This utility model relates to the field of thin-walled pier structure technology for road and bridge, specifically to an internal mold structure for thin-walled piers of road and bridge. Background Technology

[0002] Thin-walled piers are widely used in road and bridge construction due to their advantages such as lightweight structure and material saving. However, the internal space of thin-walled piers is usually quite narrow, and their internal formwork construction faces many challenges: Low efficiency in formwork assembly and disassembly: Traditional internal formwork structures are often bulky and have complex connection methods (such as a large amount of welding), resulting in long on-site assembly and disassembly times, which affects the construction progress.

[0003] High structural stability requirements: Thin-walled piers are sensitive to lateral pressure during concrete pouring, requiring the internal formwork system itself to have sufficient rigidity and overall stability to prevent bulging or deformation and ensure accurate pier geometry.

[0004] Therefore, the existing internal mold structure needs to be improved. Utility Model Content

[0005] In view of this, the present invention provides an inner mold structure for thin-walled piers of roads and bridges to solve the technical problems of low efficiency in template assembly and disassembly and low structural stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An internal formwork structure for thin-walled piers of road and bridge, comprising: Multiple sets of first inner mold frames are arranged in a ring. Multiple sets of second inner mold frames, the second inner mold frames being connected between two adjacent sets of first inner mold frames; Several connecting frames are connected to the corresponding first inner mold frame via connecting parts; The second inner mold frame is provided with a second mounting plate at both ends, and the second mounting plate is connected to the first mounting plate on the corresponding side; The second mounting plate is fixedly connected to the first mounting plate on the corresponding side by a locking member; The locking component includes a locking bolt and a nut, the second mounting plate is connected to the first mounting plate by the locking bolt, and the nut is locked onto the locking bolt; The locking element also includes a disc spring, which is sleeved on the locking bolt and abuts against the locking bolt and the second mounting plate.

[0007] Furthermore, a first mounting plate is provided at both ends of the first inner mold frame.

[0008] Furthermore, the second inner mold frame includes a connecting portion and a pair of extension portions, the pair of extension portions being obliquely connected to both ends of the connecting portion.

[0009] Furthermore, the second mounting plate is disposed at the end of the extension.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Stable and reliable overall structure: The four sets of first inner mold frames are distributed in a rectangular shape, and the four sets of second inner mold frames are connected at an incline to form an overall octagonal structure. The stress is reasonable and the integrity is strong. Channel steel is used to increase the structural rigidity and strength of the first and second inner mold frames.

[0011] 2. Modular design for easy connection and disassembly: The second inner mold frame is designed with a connecting part and inclined extensions at both ends, which allows it to naturally bridge the adjacent first inner mold frame, simplifying the connection process. The second mounting plate of the second inner mold frame is then fixed to the first mounting plate of the first inner mold frame by locking parts. Compared with welding, this greatly improves the efficiency of disassembly and assembly, and facilitates the reuse of the template.

[0012] 3. Improve construction efficiency and quality: Convenient assembly and disassembly methods and a stable operating platform help shorten the construction period; the high-rigidity structure can effectively resist the lateral pressure of concrete, ensuring the dimensional accuracy and appearance quality of the pier body.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] refer to Figures 1 to 3 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an internal formwork structure for thin-walled piers of roads and bridges, mainly composed of: multiple sets of first internal formwork frames 1, multiple sets of second internal formwork frames 2, and several connecting frames 3. The multiple sets of first internal formwork frames 1 are arranged in a ring, and the second internal formwork frames 2 are connected between two adjacent sets of first internal formwork frames 1. The connecting frames 3 are fixedly connected to the inner side of the corresponding first internal formwork frame 1 through connecting parts 5, so that the connecting frames 3 can be fixed on the first internal formwork frame 1. The connecting frames 3 serve as platforms, which facilitates the walking and operation of construction personnel, thereby improving the convenience of construction.

[0020] Preferably, four sets of first inner mold frames 1 and four sets of second inner mold frames 2 are spaced apart. The four sets of first inner mold frames 1 are rectangularly distributed, and the four sets of second inner mold frames 2 are obliquely connected to the connection points of adjacent sets of first inner mold frames 1. The second inner mold frames 2 serve to bridge the first inner mold frames 1, thus making the overall inner mold structure an octagonal structure. In addition, the inner and outer walls of the first inner mold frames 1 and the inner and outer walls of the second inner mold frames 2 are connected by several C-shaped channel steels 4 to improve the overall structural strength of the first inner mold frames 1 and the second inner mold frames 2. The second inner mold frame 2 includes a connecting part 22 and a pair of extensions 23. The pair of extensions 23 are obliquely connected to both ends of the connecting part 22, and each end of the pair of extensions 23 is provided with a second mounting plate 21.

[0021] Specifically, a first mounting plate 11 is provided at both ends of the first inner mold frame 1, and a second mounting plate 21 is welded and fixed together with the first mounting plate 11 on the corresponding side.

[0022] Preferably, as a second embodiment of the connection between the second mounting plate 21 and the first mounting plate 11, such as... Figure 4 As shown, the second mounting plate 21 is fixedly connected to the corresponding first mounting plate 11 by a locking member 6. The locking member 6 includes a locking bolt 61 and a nut 63. The second mounting plate 21 and the first mounting plate 11 are connected by the locking bolt 61, and the nut 63 is locked onto the locking bolt 61.

[0023] To improve the locking effect, the locking component 6 also includes a disc spring 62, which is sleeved on the locking bolt 61 and abuts against the locking bolt 61 and the second mounting plate 21. The disc spring 62 is elastic. When the nut 63 is tightened on the locking bolt 61, the two sides of the disc spring 62 abut against the head of the locking bolt 61 and the side of the second mounting plate 21, respectively. The elastic deformation generated by the disc spring 62 can provide continuous compensation locking force, effectively preventing the locking bolt 61 from loosening due to vibration and ensuring reliable connection.

[0024] In summary, this utility model has an overall octagonal structure. By setting a second inner mold frame 2 between two adjacent first inner mold frames 1, and dividing the second inner mold frame 2 into a connecting part 22 and a pair of extension parts 23 that both extend obliquely to the connecting part 22, the connection between the first inner mold frame 1 and the second inner mold frame 2 can be made more convenient. By setting a locking member 6, the disassembly between the first inner mold frame 1 and the second inner mold frame 2 can be made more convenient, and the design of the disc spring 62 can prevent the locking bolt 61 from loosening. By setting the channel steel 4, both the first inner mold frame 1 and the second inner mold frame 2 have good structural strength, improving the safety and durability of use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
