Description

Technical Field

[0001] The utility model relates to the technical field of bridge templates, in particular to a bridge template with corrosion resistance. Background Art

[0002] Bridge formwork is a steel formwork used in bridge projects, such as steel formwork used in highway bridges, viaducts, overpasses and other projects.

[0003] For example, a bridge formwork disclosed in the authorization announcement number CN209722742U has an isolation plate with a polished surface on the inner side of the splicing formwork, so that the splicing formwork is not in direct contact with the cast body, which makes it easy to remove the splicing formwork. At the same time, the inner side of the isolation plate is a polished surface and is not bonded to the cast body, which is also convenient for disassembly, thereby improving the efficiency of bridge project construction. However, it does not solve the problem that the existing bridge formwork is easily corroded and the connection between the bridge formwork and the fixed plate is fragile, resulting in low installation stability of the bridge formwork.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0089] When the formwork body 1 is fixed on the top of the fixed plate 3, the staff lifts the connecting shell 19 through the lifting device, and moves the movable block 21 upward through the connecting shell 19, so that the movable block 21 can move into the inner side of the bottom opening 20 under the action of external force, and then moves the connecting shell 19, so that the connecting shell 19 can be installed on the outside of the first connecting guide rail 17 and the second connecting guide rail 23 under the action of external force. When the connecting shell 19 is installed, the movable block 21 moves downward under the action of its own gravity, so that the movable block 21 can move out of the inner side of the bottom opening 20, and make the small hole of the movable block 21 correspond to the position of the threaded hole 18. The staff screws the fastening bolt 22 into the inner side of the threaded hole 18 through the inside of the small hole of the movable block 21, so that the fastening bolt 22 moves under the threaded support of the threaded hole 18, and fixes the movable block 21. By fixing the first connecting guide rail 17 and the second connecting guide rail 23, the connection and fixation between the formwork body 1 and the fixed plate 3 can be further strengthened, thereby improving the installation stability between the formwork body 1 and the fixed plate 3.

[0090] Working principle: The staff controls the lifting device to erect the two ends of the fixed plate 3 on the bridge pier, and then uses the lifting device to move the formwork body 1. By inserting the positioning column 13 into the inner side of the positioning groove 12 at the corresponding position, the formwork body 1 is erected on the top of the fixed plate 3. Use tools to screw the anchor bolt 15 into the inner side of the mounting hole 14 through the hole position of the formwork body 1. The staff moves the movable block 21 upwards, and installs the connecting shell 19 on the outside of the first connecting guide rail 17 and the second connecting guide rail 23. Then, the movable block 21 is lowered, and the fastening bolt 22 is screwed into the inner side of the threaded hole 18 through the movable block 21 to complete the installation of the bridge formwork.

[0091] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
