Technical Field

[0001] This utility model relates to the field of roof construction technology, specifically a prefabricated mold for the rounded corner of the parapet wall of a roof. Background Technology

[0002] Based on on-site construction experience, the decorative connection between the parapet wall of the roof and the roof plaza bricks is often achieved by using mortar to create a rounded corner.

[0003] According to actual on-site construction experience, it is difficult to construct rounded corners on-site using mortar. It is not easy for workers to control the arc angle of the rounded corners, and it is difficult to keep the construction thickness consistent in different parts. As a result, the appearance quality of the rounded corners after construction is poor, and this process is time-consuming.

[0004] Based on this, this utility model proposes a prefabricated mold for the rounded corner of the parapet wall of a roof. Utility Model Content

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved prefabrication mold for rounded corners of parapet walls on roofs. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, a prefabricated mold for the rounded corner of a roof parapet wall includes a right-angle back plate 1, on which two slots 4 are formed. The cross-section of the slots 4 is "T" shaped. The mold also includes:

[0025] Two locking blocks 5 are slidably connected to two locking slots 4 respectively. The cross-section of the locking blocks 5 is "T" shaped. The two locking blocks 5 are fixedly connected to the arc buckle plate 2. Different mold sizes can be customized according to different arc angle size requirements to adapt to different roof decoration effects. The right angle back plate 1 is provided with a base plate 3. Two extension plates 6 are fixedly connected to the base plate 3. The two extension plates 6 are fixedly connected to the arc buckle plate 2 through two threaded rods 7. The mold is easy to install and disassemble and can be reused multiple times.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, four connecting rods 8 are fixedly connected to the base plate 3. The cross-section of the connecting rods 8 is U-shaped, and four limiting grooves 9 are respectively opened on the four connecting rods 8.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, four fixing boxes 10 are fixedly connected to the right-angle back plate 1. Each of the four fixing boxes 10 has a slot 11, which is adapted to the connecting rod 8.

[0028] Furthermore, such as Figure 2 and Figure 3 As shown, four pull rods 12 are slidably connected inside the four fixed boxes 10. The cross-section of the pull rod 12 is "L" shaped, and the cross-section of the pull rod 12 on the side near the slot 11 is a right triangle.

[0029] Furthermore, such as Figure 3 As shown, multiple limiting plates 13 are fixedly connected to the four pull rods 12 respectively. The multiple limiting plates 13 are slidably connected to the four fixed boxes 10. The limiting plates 13 limit the pull rods 12 to prevent them from detaching from the fixed boxes 10.

[0030] Furthermore, such as Figure 3 As shown, multiple springs 14 are fixedly connected to multiple limiting plates 13 respectively. The multiple springs 14 are fixedly connected to four fixing boxes 10 respectively. Under the action of the springs 14, the pull rod 12 is always embedded in the limiting groove 9, fixing the connecting rod 8 in the fixing box 10.

[0031] The specific working method is as follows: During on-site construction, a release agent is first applied to the inner sides of the right-angle back panel 1, the arc-shaped buckle panel 2, and the base plate 3. Then, the clip 5 of the arc-shaped buckle panel 2 is embedded into the slot 4 of the right-angle back panel 1, splicing the arc-shaped buckle panel 2 and the right-angle back panel 1. Subsequently, the base plate 3 is connected to the right-angle back panel 1, so that the connecting rod 8 is embedded in the fixing box 10. The connecting rod 8 is fixed in the fixing box 10 using the pull rod 12, thereby fixing the base plate 3 and the right-angle back panel 1. Then, the extension plate 6 is fixed to the arc-shaped buckle panel 2 through the threaded rod 7, thus completing the assembly of the mold. Then, with the base plate 3 facing down, mortar or other solidifiable fixing materials are poured in from the opening. After the mortar has solidified, the arc-shaped buckle panel 2 can be removed, the formed precast mortar module can be taken out, and it can be directly placed and installed at the inside corner of the parapet wall of the roof to be constructed. Multiple precast mortar modules are assembled end-to-end to form a complete and uniform rounded corner band. Fiberglass mesh is then fixed to the surface of the precast modules, and a finishing mortar is applied to conceal the gaps between the mesh and the modules, creating a unified whole. This achieves a seamless decorative effect at the corners of the parapet wall and the roof plaza brickwork. After finishing, the rounded corners have a uniform curvature and size, creating a seamless appearance and improving the overall quality. This also reduces construction difficulty and enhances the decorative effect.

Matters not covered in this utility model are common knowledge to those skilled in the art.
