Abstract
Description
Technical Field
[0001] This utility model relates to the field of integrated bathroom technology, and in particular to a frame structure for integrated bathrooms. Background Technology
[0002] Most integrated bathroom products on the market today adopt a split frame structure design, and their assembly process relies on secondary processing methods such as welding or bolt connection.
[0003] This traditional manufacturing model has revealed significant limitations in industrial practice: First, in terms of cost control, not only is low material utilization leading to high raw material costs, but the multi-station processing characteristics also increase production energy consumption; second, in terms of process complexity, the involvement of multiple discrete processes such as cutting, drilling, and welding results in low production efficiency and fluctuating yield rates; third, in terms of labor input, it heavily relies on skilled workers for precise assembly, causing labor costs to account for a higher percentage than the industry average; more importantly, structural deformation caused by hot working processes leads to accumulated product tolerances, directly affecting assembly fit; finally, matching errors that occur during on-site installation often require secondary processing for correction. These systemic defects collectively restrict the standardization of products and market penetration. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated bathroom frame structure that can not only reduce material costs, simplify production processes, and reduce reliance on manual labor, but also improve dimensional accuracy, facilitate on-site installation, and significantly enhance product consistency.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An integrated bathroom frame structure includes two side frames spaced apart in the horizontal direction, and a front frame and a rear frame respectively located on the front and rear sides of the two side frames. The horizontal ends of the front and rear sides of the two side frames are spliced to the horizontal ends of the front frame and the rear frame respectively by splicing members. The splicing members include tenons rolled and connected to the end of any frame, and mortises rolled and connected to the end of the mating frame and corresponding to the tenons. The tenons have a U-shaped first splicing part and connecting parts extending outward in the horizontal direction from the ends of the two sides of the first splicing part. The mortises have a U-shaped second splicing part and extension arms extending outward in the horizontal direction from the ends of the two sides of the second splicing part. The first splicing part is inserted into the second splicing part and fixedly connected thereto. The connecting parts and the extension arms form a parallel overlap, thereby splicing the two side frames, the front frame, and the rear frame into the wall frame of the integrated bathroom.
[0007] Furthermore, the connecting part is roll-formed to any end of the frame, and the bottom wall of the second splicing part is roll-formed to the end of the mating frame, with its position corresponding to the first splicing part.
[0008] Furthermore, the first splicing part is inserted into the second splicing part and glued to it.
[0009] Furthermore, the rear frame includes a first rear frame and a second rear frame that is arranged horizontally side by side with and spliced with the first rear frame.
[0010] Furthermore, the front frame includes a first front frame and a second front frame arranged laterally at intervals, and a door mounting opening is formed between the proximal ends of the first front frame and the second front frame, the door mounting opening being used to install a bathroom door.
[0011] Furthermore, marble or ceramic tiles are attached to the inner surface of the wall frame using adhesive materials.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] First, reduce material costs: The frame and splicing parts are rolled and formed into an integrated design, which reduces the additional materials required for welding or bolting, improves the utilization rate of raw materials, and reduces production costs.
[0014] Second, simplify the production process: replace traditional welding or bolt fixing with plug-in structure to reduce multiple processes such as cutting, drilling, and welding, shorten the production process and improve processing efficiency.
[0015] Third, it reduces reliance on manual labor: the standardized mating method of mortise and tenon reduces the precision requirements for manual assembly, reduces the need for skilled workers, and lowers labor costs.
[0016] Fourth, improve dimensional accuracy: Roll forming process ensures the dimensional consistency of tenons and mortises, avoids tolerance accumulation caused by welding deformation, and improves the fit of product assembly.
[0017] Fifth, it facilitates on-site installation: the modular plug-in design makes frame assembly more convenient, eliminating the need for secondary processing and adjustments, improving installation efficiency and reducing construction difficulty.
[0018] Sixth, improve product consistency: Standardized components and automated rolling processes ensure high consistency of mass-produced products, improving overall quality stability. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.
[0023] like Figures 1 to 3 As shown in the embodiment of this utility model, the frame structure of an integrated bathroom includes two side frames 1 spaced apart in the horizontal direction, and a front frame 2 and a rear frame 3 respectively located on the front and rear sides of the two side frames 1. The horizontal ends of the front and rear sides of the two side frames 1 are respectively spliced to the horizontal ends of the front frame 2 and the rear frame 3 via splicing members 4. The splicing member 4 includes a tenon 41 rolled and connected to the end of any frame, and a mortise 42 rolled and connected to the end of the mating frame and corresponding to the tenon 41. Component 41 has a U-shaped first splicing portion 43 and connecting portions 44 extending horizontally outward from both sides of the first splicing portion 43. The tenon and mortise component 42 has a U-shaped second splicing portion 45 and extension arms 46 extending horizontally outward from both sides of the second splicing portion 45. The first splicing portion 43 is inserted into and fixedly connected to the second splicing portion 45. The connecting portions 44 and the extension arms 46 form a parallel overlap, thereby allowing the two side frames 1, the front frame 2, and the rear frame 3 to be spliced into an integrated bathroom wall frame. Both side frames 1, the front frame 2, the rear frame 3, and the splicing components 4 are all made of cold-rolled steel.
[0024] As described above, the connecting part 44 is rolled to any end of the frame, and the bottom wall of the second splicing part 45 is rolled to the end of the mating frame and its position corresponds to that of the first splicing part 43.
[0025] As described above, the first splicing part 43 is inserted into the second splicing part 45 and glued to it; in addition, in order to further improve the connection strength between the first splicing part 43 and the second splicing part 45, several screws can be screwed on the outside of the first splicing part 43 and the second splicing part 45 for reinforcement.
[0026] As described above, the rear frame 3 includes a first rear frame 31 and a second rear frame 32 that is arranged horizontally side by side with and spliced with the first rear frame 31.
[0027] As described above, the front frame 2 includes a first front frame 21 and a second front frame 22 arranged laterally. A door mounting opening 23 is formed between the proximal ends of the first front frame 21 and the second front frame 22. The door mounting opening 23 is used to install a bathroom door.
[0028] As described above, marble 5 or ceramic tile 6 are attached to the inner surface of the wall frame by means of an adhesive material, which is a flexible ceramic tile adhesive or ceramic tile glue.
[0029] During installation, simply insert the first splicing part 43 into the second splicing part 45 so that the connecting part 44 and the extension arm 46 are parallel and overlapped, and then fix them with adhesive. Therefore, this installation method is simple and quick, which can greatly improve the assembly efficiency on the construction site.
[0030] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
