Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically a connection and locking device for bridge templates. Background Technology

[0002] Bridge formwork is a type of steel formwork specifically designed for constructing railway or highway bridges, as well as high-speed or expressway bridges. It is widely used in bridge construction projects due to its reusability and aesthetically pleasing concrete pouring results. However, the steel formwork and its supports must possess sufficient strength, rigidity, and stability, and their supporting components should have adequate support area. Furthermore, installing beam steel formwork can easily lead to an oversized beam top, potentially causing deformation during later concrete pouring. Therefore, a steel formwork with sufficient strength and rigidity is needed to prevent deformation during concrete pouring.

[0003] Chinese Patent Publication No. CN220166692U discloses a connection and locking device for bridge formwork, including a formwork body. The formwork body is composed of a first side mold, a second side mold, a first vertical mold, and a second vertical mold arranged in a rectangle. A first locking rod is symmetrically connected between the first side mold and the second side mold, and a second locking rod is symmetrically connected between the first vertical mold and the second vertical mold. The ends of the first locking rods all protrude from the first side mold and the second side mold. The ends of the first locking rods are provided with a first horizontal insert and a first vertical insert on both the inner and outer sides of the side walls of the first side mold and the second side mold. The ends of the second locking rods all protrude from the first vertical mold and the second vertical mold. The ends of the second locking rods are provided with a second horizontal insert and a second vertical insert on both the inner and outer sides of the side walls of the first vertical mold and the second vertical mold. This utility model aims to provide a formwork connection and locking device with sufficient strength to prevent deformation of steel formwork during concrete pouring, and at the same time, effectively prevent deformation of the upper opening.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a bridge formwork connection and locking device, which is used in the assembly and locking of bridge formwork. In this embodiment, the structure of the bridge formwork connection and locking device is improved, so that it has the advantage of making it easier for workers to assemble and disassemble the connection and locking device.

[0027] Example 1:

[0028] Please see Figures 1 to 4In order to fix the mounting plate 2 more stably to the upper end of the template 1, the mounting plate 2 is detachably connected to the upper end of the template 1. Both sides of the mounting plate 2 are fixedly connected with side plates 8 for positioning, and the upper end of the side plates 8 is inserted with bolts 9 for fixing.

[0029] The side plate 8 and bolt 9 make it easier for workers to fix the mounting plate 2 to the upper end of the template 1, further ensuring the stability of the mounting plate 2 and preventing the mounting plate 2 from falling off.

[0030] Example 2:

[0031] Please see Figures 1 to 4 To facilitate adjustment of the spacing between the two templates 1 by staff according to actual conditions, a positioning frame 3 is detachably connected to the middle of the upper end of the mounting plate 2 for fixing. A lead screw 4 for adjustment is snapped into the side of the positioning frame 3. One end of the lead screw 4 is threaded to a connecting shaft 5 for rotation. A positioning block 6 is fixedly connected to the outer surface of the connecting shaft 5. A screw 10 for fixing is inserted into the lower end of the positioning frame 3. The screw 10 passes through the lower end of the positioning frame 3 and is threaded to the upper end of the mounting plate 2. A positioning bracket 11 is fixedly installed on the upper end of the plate 2. A limiting sleeve 12 is fixedly connected to the side of the bracket 11. A screw 13 is inserted into the lower end of the bracket 11. The screw 13 passes through the upper end of the bracket 11 and is threaded to the upper end of the mounting plate 2. A positioning guide rod 14 is snapped into one end of the sleeve 12. A support rod 15 is fixedly connected to the lower end of the sleeve 12. A positioning fixing plate 16 is fixedly connected to the lower end of the support rod 15. A positioning pin for fixing is inserted into the upper end of the fixing plate 16.
