Description

Technical Field

[0001] This invention relates to the field of sunken bathroom construction, specifically to a casting template for sunken bathrooms. Background Technology

[0002] Sunken bathrooms are widely used in building construction. Current technology for laying formwork in cast-in-place concrete sunken bathrooms has the following areas for improvement: Firstly, after traditional formwork is erected and concrete is poured, the inner corners of the bathroom need to be rounded before waterproofing. However, with numerous pipes inside the bathroom, rounding is extremely inconvenient. The side of the vertical water supply and drainage pipes against the wall cannot be rounded at all. Furthermore, the rounded corners are formed later and are prone to cracking, especially at the contact points with the wall panels. The quality of the rounded corner construction directly affects the quality of the subsequent waterproofing process, particularly the waterproofing membrane, which is prone to breakage at the rounded corners, leading to bathroom leaks. Secondly, to ensure the overall waterproofing effect of the bathroom, current technology typically requires a 20cm high concrete curb at the bottom of the walls around the bathroom, poured together with the main structure. However, traditional formwork (hanging formwork) is not systematically assembled and difficult to fix, leading to formwork displacement and deformation, resulting in misalignment and unevenness of the curb. This necessitates manual repair, which is time-consuming, labor-intensive, and affects quality.

[0003] Therefore, to solve the above problems, a casting formwork for sunken toilets is needed that can simplify the construction process, reduce construction costs, and improve construction quality. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a casting template for sunken toilets, which can simplify the construction process, reduce construction costs, and improve construction quality.

[0005] The present invention provides a casting template for sunken toilets, comprising a side formwork structure, wherein the side formwork structure includes an inner formwork, an outer formwork, and a limiting component, wherein the limiting component includes a positioning lock and a limiting lock buckle;

[0006] The bottom of the inner template has an R-angle that smoothly transitions inward;

[0007] The limiting latch is driven to move closer to or further away from the positioning lock and is limited at a set position; the positioning lock is located inside the inner template and the limiting latch is located outside the outer template.

[0008] In use, the distance between the inner and outer templates is adjusted by moving the limiting latch and positioning lock closer or further away.

[0009] Furthermore, the limiting components are installed on top of the inner and outer templates during use, and there are several sets of the limiting components.

[0010] Furthermore, the side mold structure is composed of several groups, and the several groups of side mold structures are connected in a predetermined order to form a side mold of a predetermined shape.

[0011] Furthermore, it also includes a support reinforcement component, which is disposed on the side mold and is used to limit a set number of side mold structures to their respective set positions.

[0012] Furthermore, the length of the supporting reinforcement is adjustable.

[0013] Furthermore, the inner template has inner plate secondary ribs on its inner side, and the outer template has outer plate secondary ribs on its outer side.

[0014] Furthermore, the bottom of the positioning lock is close to the bottom R-corner of the inner template, and the top of the positioning lock extends outward from the top edge of the inner template to form a connecting part;

[0015] The limiting lock is located on the connecting part.

[0016] Furthermore, the connecting part has a sliding groove. In use, the limiting lock is driven to slide inward or outward on the sliding groove and is limited to the connecting part at a set position, thus limiting the inner template and the outer template.

[0017] Furthermore, it also includes an inner bottom mold and an outer bottom mold, wherein the inner bottom mold connects several inner templates in the side mold, and the outer bottom mold connects several outer templates in the side mold.

[0018] Furthermore, both the inner and outer templates are prefabricated components.

[0019] The beneficial effects of this invention are as follows: This invention discloses a casting template for sunken toilets, in which the outer template is a rectangular plate and the inner template is a rectangular plate with rounded corners at the bottom. During assembly, a casting cavity is formed between the inner and outer templates. A total of four sets of side molds are set up to form a rectangular cube side mold after being connected. It also includes an inner bottom mold and an outer bottom mold. The inner bottom mold connects several inner templates in the side molds, and the outer bottom mold connects several outer templates in the side molds, so that the casting cavity of the side molds and the bottom molds is continuous. During casting, a sunken toilet with rounded corners can be directly formed, which solves the drawbacks of the difficulty in implementing rounded corners in the prior art and the problem of poor construction quality. It is beneficial to the subsequent waterproofing construction, and is convenient to implement with better construction quality. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Figure 2 This is a cross-sectional structural diagram of the present invention;

[0024] Figure 4 This is a top view of the limiting component of the present invention. Detailed Implementation

[0025] Figures 1-4 As shown in the figure, the casting template for a sunken toilet in this embodiment includes a side formwork structure. The side formwork structure includes an inner formwork 1, an outer formwork 2, and a limiting component. In this solution, both the inner formwork 1 and the outer formwork 2 are prefabricated components. The inner formwork 1 and the outer formwork 2 are plate-shaped, and the bottom of the inner formwork 1 has an inwardly smoothly transitioning bend with an R-angle 3. The side formwork structure consists of several groups, which are connected in a predetermined order to form a side formwork of a predetermined shape. This solution is illustrated using a sunken rectangular toilet as an example. The outer formwork 2 is a rectangular plate, and the inner formwork 1 is a rectangular plate with an R-angle 3 at the bottom. During assembly, a pouring cavity is formed between the inner formwork 1 and the outer formwork 2, so that the R-angle 3... Simultaneous pouring with the main structure simplifies the process and ensures construction quality. This scheme sets up four sets of side molds that connect to form a rectangular cube, and also includes an inner bottom mold 4 and an outer bottom mold 5. The inner bottom mold 4 connects several inner templates 1 in the side mold, and the outer bottom mold 5 connects several outer templates 2 in the side mold, so that the pouring cavity of the side mold and the bottom mold is continuous. During pouring, a sunken toilet with an R-angle 3 can be directly formed, solving the drawbacks of the existing technology that the R-angle 3 is difficult to implement and the problem of poor construction quality. It is beneficial to the subsequent waterproofing construction, and is easy to implement with better construction quality. This scheme is also applicable to the one-time pouring construction of sunken buildings with an R-angle 3 of other shapes. The shape of the side mold is designed according to actual needs, which will not be elaborated here.

[0026] In this embodiment, the inner template 1 has inner panel secondary ribs 6 on its inner side. The inner panel secondary ribs 6 are integrally formed in a rectangular grid shape on the inner side of the inner template 1, and the inner panel secondary ribs 6 protrude from the inner side of the inner template 1. The outer template 2 has outer panel secondary ribs 7 on its outer side. The outer panel secondary ribs 7 are integrally formed in a rectangular grid shape on the outer side of the outer template 2, and the outer panel secondary ribs 7 protrude from the outer side of the outer template 2. The inner side refers to the side facing the interior of the sunken building when in use. The outer side is opposite to the inner side, and will not be described further here. The secondary ribs 6 on the inner panel and 7 on the outer panel are arranged on the inner formwork 1 and outer formwork 2 respectively, which can improve the reliability of the side formwork and improve the construction quality. The inner formwork 1 and outer formwork 2 of this solution are customized according to the construction requirements and are steel formwork. When assembling adjacent inner formwork 1 or outer formwork 2, they can be fastened by means of clamping or binding using existing technology, which is convenient and quick to construct and conducive to reuse, thus reducing costs. In another embodiment, the inner formwork 1 and outer formwork 2 can also be a sheet-like assembly structure, which can be assembled by means of hinge connection or pin connection, etc., which can adjust the shape and length of use according to the building requirements, improving the versatility of use, which will not be elaborated here.

[0027] In this embodiment, the limiting component includes a positioning lock 8 and a limiting latch 9. The limiting latch 9 is driven to move closer to or further away from the positioning lock 8 and is limited at a set position. The positioning lock 8 is located inside the inner template 1, and the limiting latch 9 is located outside the outer template 2. In use, the distance between the inner template 1 and the outer template 2 is adjusted by moving the limiting latch 9 and the positioning lock 8 closer to or further away. This allows the thickness of the poured structure to be controlled and meet preset indicators. The limiting component is installed on top of the inner template 1 and the outer template 2. Several sets of the limiting component are used to improve the connection reliability between the inner template 1 and the outer template 2, ensuring that the mold does not deform or shift, thereby solving the problems of misalignment and unevenness in the pouring of the reverse slope, avoiding secondary chiseling, and ensuring construction quality.

[0028] In this embodiment, the bottom of the positioning lock 8 is close to the bottom R-angle 3 of the inner template 1, which enhances the limiting ability of the inner template 1. The top of the positioning lock 8 extends outward from the top edge of the inner template 1 and bends outward to form a connecting part. As shown in the figure, the positioning lock 8 is L-shaped and is used upside down to hold the inner template 1 against it. The limiting latch 9 is provided on the connecting part. The connecting part has a sliding groove 10. Specifically, the sliding groove 10 is opened perpendicular to the surface of the inner template 1 in this embodiment. When in use, the limiting latch 9 is driven to slide inward or outward on the sliding groove 10 and to a set position. The inner template 1 and outer template 2 are clamped and secured at the connecting part. In this design, the limiting lock 9 is locked to the connecting part by bolts 11. The sliding groove 10 on the connecting part is a U-shaped groove with an open end. The limiting lock 9 is T-shaped and inserted into the sliding groove 10, with the top of the T-shape supported by the top of the connecting part. The bolts 11 are arranged on the open side of the U-shaped groove 10 and are used to limit the limiting lock 9 to the connecting part. In use, after the limiting lock 9 is adjusted to its position, it hangs down naturally. Tightening the bolts 11 and the matching nuts will limit the limiting lock 9. In another embodiment, the limiting lock 9 has a lug with a nut. The bolt passing through the U-shaped groove 10 is also threaded to the nut. This structure eliminates the need for a separate nut arrangement; the position of the limiting lock 9 can be adjusted and limited by tightening or loosening the bolts, resulting in higher construction efficiency.

[0029] In this embodiment, a supporting reinforcement component is also included. This component is disposed on the side mold and is used to limit a set number of side mold structures to their respective set positions. The length of the supporting reinforcement component is adjustable. In this design, the supporting reinforcement component is mesh-like and consists of several L-shaped limiting rods 12. During use, the hooks of the L-shaped limiting rods 12 are positioned at the outer template 2, and adjacent limiting rods 12 are fastened together by locking buckles. The locking buckles are preferably clamps 13. The structure is easy to implement and convenient to assemble and disassemble. It can also be used for cable ties or rebar binding, etc., which will not be elaborated further here.

[0030] This embodiment effectively solves the problems of difficult implementation of R-angle 3 and easy cracking when implemented alone, providing a good base layer for the subsequent waterproofing process and reducing the risk of bathroom leakage; R-angle 3 is cast in one piece with the main body, saving the base cleaning and labor costs before implementing R-angle 3 separately, simplifying the process and saving costs; the bathroom curb is cast in one piece with the main body, and the curb forming lines are vertical and smooth, avoiding secondary chiseling and saving repair costs; different sizes of integral molds are configured according to different sizes of sunken bathrooms, and the integral molds are easy to assemble and disassemble with high reusability, reducing the consumption of turnover materials and saving material costs.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
