Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier casting construction, in particular to a bridge pier construction casting template structure. Background Art

[0002] As the basic supporting structure of the bridge, the pier plays an important role. In the construction of piers, pier formwork is usually used as a forming tool to cast piers of corresponding shapes and sizes. Due to the large size of the piers, the corresponding pier formwork size is also large. In the process of pouring concrete, the pier formwork needs to be spliced ​​on site first. After splicing, the joints of the formwork need to be welded and fixed. After the piers are cast, a cutting machine needs to be used to cut and demould the welds of the pier formwork.

[0003] The existing (Announcement No.: CN218205661U) discloses a casting frame fixed formwork structure for building construction projects, which limits two baffles in the plug-in grooves through a limiting component, thereby facilitating the construction workers to assemble the casting frame fixed formwork structure; when the construction workers disassemble and remove the casting frame fixed formwork structure, they first release the limiting and binding effect of the limiting component on the fixed block, and then remove the fixed block from the end positions of the two baffles, that is, the fixed block releases the limiting and fixing effect on the two baffles, and then sequentially detaches the clamping blocks from the positions of the clamping grooves, so that the two baffles are released from the clamping connection with the two connecting plates, thereby quickly and conveniently realizing the disassembly work of the casting frame formwork fixed structure.

[0004] Although the above patent ensures convenient installation and disassembly, the method of only fixing the connection and limiting the fixing block at the center of the baffle cannot ensure that the poured concrete will not be deformed or burst at the connection, or even cause construction failure, thereby reducing the reliable strength of the formwork during casting.

[0008] Optionally, the groove wall of the groove is configured as a sealing surface that fits against the inner sealing protrusion.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model comprises a first angle reinforcement plate, a second angle reinforcement plate and an outer sealing reinforcement plate connected at the angle and connection of the first formwork and the second formwork.

[0014] 2. The utility model adopts the design that the reinforcing slide bar slides in the slide groove and is threadedly fixed with the fixed groove plate, so that when the construction workers install the first template and the second template, they only need to slide the reinforcing slide bar in the slide groove in turn, slide it downward until it fits with the fixed groove plate, and then thread it with bolts to stabilize the connection of the templates. When disassembling, they only need to remove the bolts by thread and slide the reinforcing slide bar upward in the slide groove to take it out.

Two sets of auxiliary reinforcement rods 16 are fixedly connected between the first angle reinforcement plate 9 and the two outer sealing reinforcement plates 10.

[0022] More specifically, in this embodiment, when installing the first formwork 1 and the second formwork 2, the construction workers only need to slide the reinforcing slide rod 13 into the slide groove 12 in turn, and slide downward until it fits with the fixed groove plate 14, and then threadably fix it with the bolts 15 to stabilize the connection of the formwork. When disassembling, they only need to threadably remove the bolts 15 and slide the reinforcing slide rod 13 upward in the slide groove 12 to remove it. The operation is simple, which improves the convenience of installation and disassembly of the formwork structure.
