Description

Technical Field

[0001] The utility model relates to the technical field of modular buildings, in particular to a modular building water supply and drainage structure. Background Art

[0002] Modular construction is a construction method that divides a building into multiple independent modules, manufactures and prefabricates them in a factory, and then transports them to the site for assembly. Each module usually includes elements such as walls, floors, ceilings, and interior decoration. In the actual application of modular construction, the water supply and drainage system is a vital part of the building.

[0003] The traditional modular building water supply and drainage method is side water supply and side drainage. However, for the pre-buried points facing the commercial street, the original water supply and drainage form is not convenient to reserve connections. It is necessary to weld pipes multiple times on the outside of the building to achieve its function. The welded pipes are directly exposed to the outside of the building, which can easily affect the appearance of the building and is difficult to repair.

[0004] Therefore, a modular building water supply and drainage structure that is easy to look at and maintain is needed to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a modular building water supply and drainage structure, aiming to solve the problem that the original water supply and drainage form proposed in the background technology is inconvenient to reserve connections, and multiple pipe fittings need to be welded on the outside of the building to achieve its function, while the welded pipe fittings are directly exposed to the outside of the building, which easily affects the appearance of the building and is difficult to repair.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular building water supply and drainage structure, which includes a water supply module and a drainage module arranged on the modular building floor; by designing the water supply module and the drainage module to be hidden inside the modular building and not exposed outside the modular building, the appearance of the building can be made neat and beautiful; at the same time, the water supply module and the drainage module are arranged on the building floor instead of being fixed on the wall, so that they can be relatively easily moved, replaced or reconfigured, which is convenient for maintenance.

[0009] In order to realize the water supply of modular buildings, the water supply module includes a reserved water inlet main pipe fixedly installed on the modular building floor, a water inlet branch pipe buried under the modular building floor and connected to the public water supply facilities, and a flow control component fixedly connected between the reserved water inlet main pipe and the water inlet branch pipe for adjusting the flow rate; through the set reserved water inlet main pipe and water inlet branch pipe, the water source in the drainage public facilities can be transported to the building for use, and at the same time, through the set flow control component, the size and speed of the water flow can be adjusted, thereby ensuring the stability and uniformity of the water flow.

[0010] In order to achieve drainage of modular buildings, the drainage module includes a reserved drainage main pipe fixedly installed on the modular building floor, a drainage pipe buried under the modular building floor and connected to the public drainage facilities, and a check piece fixedly connected between the reserved drainage main pipe and the drainage pipe for preventing fluid backflow; through the set reserved drainage main pipe and drainage pipe, the sewage used in the building can be discharged into the public drainage facilities in a centralized manner, and at the same time, the set check piece can effectively prevent sewage from flowing back into the building, reducing the health and environmental problems caused by sewage backflow.

[0011] Preferably, in order to facilitate regular maintenance of the water supply and drainage structure, inspection covers are provided at the locations of the water supply module and the drainage module; once the water supply and drainage structure fails or requires maintenance, maintenance personnel can directly open the inspection cover and enter the module to perform maintenance operations without the need to dismantle or modify the entire building structure, thereby greatly saving maintenance time and costs.

[0012] Preferably, in order to facilitate the regulation of the flow rate of the fluid, the flow control component is a PPR ball valve; the on-off or flow rate of the water flow can be controlled simply by rotating the ball on the PPR ball valve, making the operation more convenient and quick, and can greatly improve work efficiency.

[0013] Preferably, in order to simply and effectively prevent the backflow of sewage, the check member is a check valve; the structure of the check valve is very simple, and only a piston or a ball is needed to realize the switch control of the valve, so that the check valve is easy to operate and not prone to failure, thereby ensuring the stability and reliability of the system.

[0014] Preferably, in order to prevent gas backflow, the drainage pipe has an S-shaped structure; when the water flow in the drainage module stops, a water seal layer will be formed at the bend of the S-shaped structure, thereby preventing gas backflow and keeping the indoor air fresh and hygienic.

[0015] (III) Beneficial effects

[0016] The water supply and drainage structure hides the water supply module and the drainage module inside the modular building and does not expose them outside the modular building, which can make the building look neat and beautiful. At the same time, the water supply module and the drainage module are set on the floor of the building instead of fixed on the wall, so they can be moved, replaced or reconfigured relatively easily, which is convenient for maintenance.
