Description

Technical Field

[0001] This utility model relates to the field of building construction leak prevention technology, specifically a leak-proof mechanism for cast-in-place elastic decorative molding templates. Background Technology

[0002] In the field of architectural decoration, cast-in-place concrete construction is a widely used technology. By using decorative formwork, diverse shapes of building components can be achieved, enhancing the aesthetics of the building. Among them, flexible decorative formwork is favored in cast-in-place construction due to its good flexibility and adaptability. However, in actual construction, the sealing problem of the contact surface between the formwork and the concrete or concrete poured at different times has always been a key factor affecting the construction quality.

[0003] In traditional cast-in-place construction, the sealing of formwork mainly relies on simple tools and materials such as bolts and tape. These methods often fall short when faced with complex shapes and high precision requirements, especially in the application of elastic decorative formwork. Due to the elastic deformation of the formwork and the fluidity of concrete, leakage problems occur frequently, which not only affect the appearance quality of building components but may also lead to a decrease in structural strength. At the same time, traditional leakage prevention measures are cumbersome in construction operations, requiring a lot of manpower and time for formwork installation and sealing, which increases construction costs and time.

[0004] Therefore, a leak-proof mechanism is proposed for cast-in-place elastic decorative molding templates. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof mechanism for cast-in-place elastic decorative molding templates, so as to solve the problems mentioned in the background art.

[0007] Preferably, the interior of the two-layer casting outer mold is provided with a second internal threaded bolt seat, the second bolt passes through the second corner seat and the third corner seat, and is threadedly installed in the second internal threaded bolt seat located inside the two-layer casting outer mold.

[0008] Preferably, the filling layer after filling the cavity is in contact with the interface on the side near the second casting layer.

[0009] Preferably, the filled layer is about mm higher than the original casting surface to ensure a sealing effect with the surrounding contact surfaces, and the filled layer is supported by an elastic STOPOFF material.

[0010] The bottom leak-proof layer is made of sponge tape material, and the concrete texture surfaces of the first and second pouring layers are provided with release agent to avoid tape adhesion and contamination on the texture surface and to enhance the bolt tightening effect.

[0011] Preferably, the support is a side support plate, which is made of stainless steel.

The other end of the locking bolt passes through the first support platform and is inserted into the interior of the second support platform. The tops of the first and second support platforms abut against the bottoms of the first and second corner seats, respectively, facilitating adjustment according to actual support requirements.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In order to further improve the sealing performance of the contact surface between the formwork and the concrete layer or the concrete layers poured at different times during construction, this utility model provides support by setting a first corner seat and a second corner seat at the contact surface, and strengthens the sealing performance at the interface by filling the filling layer inside the filling cavity.

[0025] In this embodiment, the filling layer 10 after filling the cavity 9 comes into contact with the interface on the side near the second casting layer 2. The filling layer 10 after filling is about 5mm higher than the original casting surface to ensure the sealing effect between it and the surrounding contact surface. The filling layer 10 is supported by an elastic STOPOFF material.

[0026] In this embodiment, the bottom leak-proof layer 8 is made of sponge tape material, and the concrete texture surface of the first pouring layer 1 and the second pouring layer 2 is provided with a release agent to avoid tape adhesion and contamination on the texture surface and to enhance the bolt locking effect.
