Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a composite chassis for a box-type bathroom pipe. Background Technology

[0002] Traditional building drainage chassis construction often employs on-site casting or assembly methods, which suffers from complex procedures, long construction cycles, difficult maintenance, and inconsistent quality. Furthermore, the construction industry's shift towards prefabricated and green construction demands chassis with factory prefabrication and on-site installation capabilities.

[0003] Therefore, how to create a new type of composite chassis for bathroom pipes is one of the important research and development topics at present. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a modular composite chassis for bathroom pipes, which allows the pipes and chassis to be prefabricated in the factory in a modular composite manner, eliminating the need for on-site casting or assembly. This ensures both accuracy and quality, facilitates installation and construction, and is suitable for mass production and construction, thereby overcoming the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model provides a box-type bathroom pipe composite chassis, including a chassis frame, pipes and filling aggregate;

[0006] The chassis frame is a closed-bottom frame structure, including a bent bottom plate and several bottom beams. The bent bottom plate is U-shaped, with the top of the left and right sides bent outward at 90°. Several bottom beams are horizontally and equally spaced between the two sides of the bent bottom plate. The first and last bottom beams are flush with the front and rear end faces of the bent bottom plate. Each bottom beam has pipe installation holes opened at the designed positions, and the pipes are inserted into the pipe installation holes. The chassis frame is filled with cast-in aggregate.

[0007] As an improvement of this utility model, four closed lifting rings are installed at the four corners of the chassis frame.

[0008] Furthermore, the bottom of the closed lifting ring is machined with external threads, and the top surfaces of the two bottom beams at the ends are opened with internal threaded holes. The closed lifting ring is connected to the two bottom beams at the ends by threads.

[0009] Furthermore, the bottom beams are made of C-shaped steel profiles, with the C-shaped openings of the first and last bottom beams facing the inside of the chassis frame.

[0010] Furthermore, a gasket is installed between the pipe and the pipe mounting hole for temporarily fixing the pipe and adjusting the pipe slope.

[0011] With this design, the present invention has at least the following advantages.

[0012] 1. Compared with the traditional on-site pouring which requires manual formwork, pipe laying, pouring and curing, this utility model transfers the core process to a standardized factory environment, which greatly shortens the construction cycle, improves construction efficiency and avoids the quality instability caused by the difference in the skills of on-site workers.

[0013] 2. The modular composite chassis facilitates overall hoisting, improves the installation efficiency of docking with steel structure modules, reduces construction waste, and meets the requirements of green construction.

[0014] 3. Dry construction methods are used on-site, which facilitates cross-construction or parallel construction with other processes.

[0015] 4. The composite chassis is prefabricated in the factory in a modular manner, which can more effectively ensure the density of aggregates, ensure consistent quality of all products, and is suitable for mass production, reducing labor and maintenance costs. Attached Figure Description

[0021] Please see Figures 1 to 2 This utility model provides a box-type bathroom pipe composite chassis, including chassis frame 1, pipe 2 and filling aggregate 3.

[0022] The chassis frame 1 includes a bent bottom plate 11 and a bottom beam 12.

[0023] The bent base plate 11 is U-shaped, with the top of the left and right sides bent outward at 90° to form a flange.

[0024] The bottom beams 12 are made of C-shaped steel profiles and are horizontally welded at equal intervals between the left and right facades of the bent base plate 11. The number and spacing of the bottom beams 12 are determined according to the overall dimensions of the chassis frame 1. In this embodiment, there are 5 bottom beams 12. The C-shaped openings of the first and last bottom beams 12 face the interior of the chassis frame 1, that is, the web of the C-shaped steel profile is flush with the front and rear end faces of the bent base plate 11, so that the chassis frame 1 forms a frame structure that is closed circumferentially and on the bottom surface.

[0025] The bottom beam 12 has pipe installation holes 13 opened at the designed positions, and the pipe 2 passes through the pipe installation holes 13.

[0026] In this embodiment, pipe 2 is made of PVC. The inner diameter of the pipe mounting hole 13 is slightly larger than the outer diameter of pipe 2. During installation, a gasket is installed between pipe 2 and pipe mounting hole 13. The slope of pipe 2 is adjusted by the gasket to meet the requirements for drainage pipe slope in the "Code for Acceptance of Construction Quality of Building Water Supply, Drainage and Heating Engineering". Another function of the gasket is to temporarily fix pipe 2 to prevent displacement of pipe 2 in subsequent processes and to avoid damage caused by collision with pipe mounting hole 13. After pipe 2 is adjusted and positioned, a ball-passing test is performed. After the test is passed, pipe 2 is fixed in place.

[0027] The filler aggregate 3 is poured inside the chassis frame 1, enclosing the pipe 2 inside (with the pipe opening left outside). During pouring, a mold is used to seal the filler aggregate 3, ensuring that it is dense and free of air bubbles. After solidification, it forms an integral structure with the chassis frame 1 and the pipe 2.

[0028] Four closed lifting rings 4 are installed at the four corners of the chassis frame 1.

[0029] Specifically, the bottom of the closed lifting ring 4 is machined with external threads, and the top surfaces of the first and last bottom beams 12 near their ends have internal threaded holes 14. The closed lifting ring 4 is connected to the first and last bottom beams 12 by threads. The closed lifting ring 4 is installed before on-site hoisting. After the composite chassis is hoisted into place and welded and fixed to the steel structure beams, it is then removed.

[0030] This utility model, through modular prefabrication in the factory, can effectively ensure accuracy and quality, and is convenient and quick to install on site. It has the advantages of high efficiency, high precision, and high durability, and is suitable for the construction of various building drainage systems. It is suitable for mass production and construction, and reduces labor and maintenance costs.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
