Description

Technical Field

[0001] This utility model relates to the field of engineering template technology, and in particular to a water-stop copper sheet protective template. Background Technology

[0002] In hydraulic engineering structures, copper waterstops are commonly used for seepage prevention and water sealing at construction joints. These waterstops are typically installed inside the concrete structure at the construction joint, near the water-facing side. Because the waterstops are embedded in the left and right concrete structures at the construction joint, half of the waterstop on the first completed concrete structure will be exposed, awaiting coverage by the later-completed concrete. The area near the waterstop, with half of it exposed, cannot be covered with flat formwork. If steel formwork is used to install the waterstop against the waterstop from top to bottom, the removal of the entire steel formwork during demolding would damage the waterstop. The current conventional method is to use flat steel formwork to support the concrete structure, and wooden formwork spliced ​​together for a 10cm area above and below the waterstop. During demolding, the low hardness of the wooden formwork allows it to be easily broken, preventing damage to the waterstop.

[0003] The existing copper sheet formwork for waterstops uses wooden formwork for upper and lower splicing. Cutting and assembling the wooden planks on-site is time-consuming and inefficient. The wooden formwork is for single use, resulting in high construction costs. The lower wooden formwork can only be connected and fixed to the steel formwork via the outer horizontal and vertical ribs; there is no direct connection between the wooden and steel formwork. Furthermore, the upper wooden formwork is a separate unit; only the horizontal ribs can be externally fixed, and the inner side can only be tied with steel bars, leading to low stability. Utility Model Content

[0004] The purpose of this utility model is to provide a water-stop copper sheet to protect the formwork, so as to alleviate the problems of low construction efficiency, high construction cost and low stability of existing wooden formwork splicing construction.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A protective template for a water-stop copper sheet includes: an upper template, a lower template, and a rotating axle. The upper template and the lower template are rotatably connected via the rotating axle. The upper template is provided with a connection structure for connecting with the water-stop copper sheet.

[0007] Furthermore, the upper template and the lower template are aligned, and the rotating wheel axle is located on the side close to the upper template.

[0008] Furthermore, a limit structure is provided on the inner side of the rotating wheel axle.

[0009] Furthermore, the limiting structure includes a limiting block, which protrudes from the side wall of the rotating wheel shaft.

[0010] Furthermore, the connection structure includes an expansion joint baffle, which is disposed on the side of the upper template near the lower template, and is used to engage with the expansion joint of the water-stop copper sheet.

[0011] Furthermore, the expansion joint baffle includes a plug-in portion, which is bent toward the lower template and can be plugged into the expansion joint of the water-stop copper sheet.

[0012] Furthermore, both the upper template and the lower template are provided with installation structures for connecting with standard flat steel templates.

[0013] Furthermore, the mounting structure includes template bolt holes, which are located in the middle of the upper template and the lower template.

[0014] Furthermore, the upper template includes an upper template body and an upper rotating part, the template bolt holes are provided in the upper template body, and the rotating wheel axle is provided in the upper rotating part.

[0015] Furthermore, the lower template includes a lower template body and a lower rotating part, the template bolt holes are provided in the lower template body, and the rotating wheel axle is provided in the lower rotating part.

[0032] Example 1

[0033] The existing copper sheet formwork for waterstops uses wooden formwork for upper and lower splicing. Cutting and assembling the wooden planks on-site is time-consuming and inefficient. The wooden formwork is for single use, resulting in high construction costs. The lower wooden formwork can only be connected and fixed to the steel formwork via the outer horizontal and vertical ribs; there is no direct connection between the wooden and steel formwork. Furthermore, the upper wooden formwork is a separate unit; only the horizontal ribs can be externally fixed, and the inner side can only be tied with steel bars, leading to low stability.

[0034] In view of this, the present utility model provides a water-stop copper sheet protection template, including: an upper template 100, a lower template 200 and a rotating axle 300, the upper template 100 and the lower template 200 are rotatably connected by the rotating axle 300, and the upper template 100 is provided with a connection structure for connecting with the water-stop copper sheet 700.
