Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a pipeline connection system for an assembled building module box body. Background Art

[0002] During the on-site construction process of traditional building water supply and drainage systems, the water supply and drainage pipelines of upper and lower floors are all installed on the project site, and the pipeline connections also adopt traditional construction techniques, which are time-consuming and laborious, and the labor cost is relatively high. With the vigorous development of assembled buildings, this construction technology is being phased out, and instead, a new connection technology suitable for new buildings has emerged.

[0003] Assembled buildings require that the water supply and drainage pipelines be integrally pre-installed in the building modules by means of assembled construction methods, and only the water supply and drainage pipeline connections between the module buildings are carried out on the project site. However, traditional water supply and drainage pipelines are usually fixed in assembled buildings, and their positions cannot be adjusted. Therefore, when installation errors occur, they cannot adapt to large installation errors, and their adjustability is poor and needs to be improved. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a pipeline connection system for an assembled building module box body, which can adjust installation errors and ensure the accuracy requirements when the pipelines of each layer are docked.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A pipeline connection system for an assembled building module box body, comprising:

[0006] Multi-story building boxes, stacked on top of each other, and a pipeline well is formed at one of the corner positions. Installation holes are provided at the bottom plate position of the building box, and a maintenance port communicating with the installation holes is provided at the top plate position;

[0007] A water supply pipeline, vertically arranged in the pipeline well and aligned with the installation holes and the maintenance port;

[0008] A drainage pipeline, vertically arranged in the pipeline well and aligned with the installation holes and the maintenance port;

[0009] A fixing mechanism for fixing the water supply pipeline and the drainage pipeline and for realizing the position adjustment of the water supply pipeline and the drainage pipeline.

[0010] The utility model can be further configured as follows in a preferred example: the fixing mechanism includes a fixing frame, an adjusting plate, an adjusting rod, a fixing rod, a nut and a spring; the fixing frame is U-shaped and horizontally arranged on the inner wall of the pipe well; the adjusting plate is horizontally arranged on the surface of the fixing frame; the adjusting rod is horizontally rotatably connected to the two ends of the fixing frame and is threadedly connected to the two ends of the adjusting plate; the fixing rod is U-shaped and its two ends pass through the adjusting plate and the fixing frame; the adjusting plate and the fixing frame are provided with strip holes for the fixing rod to slide laterally; the nut is threadedly connected to the two ends of the fixing rod; the spring is sleeved on the two ends of the fixing rod and is located between the nut and the fixing frame.

[0011] In a preferred example, the utility model can be further configured as follows: it also includes a water supply connection section and a drainage connection section, the upper end of the water supply connection section is provided with an internal threaded joint, and the lower end is provided with a female flexible joint, the lower end of the water supply pipe is provided with an external threaded joint, and is 5 cm away from the bottom of the box, the upper end of the water supply pipe is provided with a male flexible joint, the drainage connection section is provided between the upper and lower layers of the water supply pipes, and the lower end of the drainage pipe is provided with a straight-through connection port.

It only needs to connect the longitudinal pipes at the junction through the inspection port to ensure the systematicness and integrity of the water supply and drainage system inside the building box.

Detailed implementation manners

[0021] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Embodiment 1:

[0023] As shown in Figure 1 , Figure 2 , Figure 3 shown, a pipe connection system for an assembled building module box body includes a multi-story building box body 1, a water supply pipe 2, a drainage pipe 3, a water supply connection section 4, and a drainage connection section 5.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 shown, the multi-story building box bodies 1 are stacked on top of each other, and a pipe shaft 11 is formed at one of the corner positions. Mounting holes 12 are provided at the bottom plate position of the building box body 1, and inspection openings 13 communicating with the mounting holes 12 are provided at the top plate position.

[0025] As shown in Figure 1 , Figure 2 , Figure 3 shown, the water supply pipe 2 is vertically arranged in the pipe shaft 11 and is aligned with the mounting hole 12 and the inspection opening 13. A male straight 21 is provided at the lower end of the water supply pipe 2, and it is 5 cm away from the bottom of the box body. A male union 22 is provided at the upper end of the water supply pipe 2.

[0026] As shown in Figure 1 , Figure 2 , Figure 3 shown, the drainage pipe 3 is vertically arranged in the pipe shaft 11 and is aligned with the mounting hole 12 and the inspection opening 13. A straight connection port 31 is provided at the lower end of the drainage pipe 3.

[0027] As shown in Figure 1 , Figure 2 , Figure 3As shown, the water supply connection section 4 is arranged between the upper and lower water supply pipes 2. An internal thread union 41 is provided at the upper end of the water supply connection section 4, and a female quick coupling 42 is provided at the lower end. The drainage connection section 5 is arranged between the upper and lower water supply pipes 2.

[0028] When assembling the prefabricated building, lift the building boxes 1 and stack them together, and then take out the water supply connection section 4 and the drainage connection section 5 for installation.

[0029] First, connect the internal thread union 41 at the upper end of the water supply connection section 4 to the external thread union 21 at the lower end of the upper water supply pipe 2, and connect the female quick coupling 42 at the lower end of the water supply connection section 4 to the male quick coupling 22 at the lower end of the lower water supply pipe 2 to realize the connection between the upper and lower water supply pipes 2.

[0030] Then, insert the upper end of the drainage connection section 5 into the straight-through connection port 31 at the lower end of the upper drainage pipe 3, and then screw the drainage expansion joint at the lower end of the drainage connection section 5 tightly onto the upper end of the lower drainage pipe 3. And both ends of the drainage connection section 5 are connected and fixed by caulking to realize the connection between the upper and lower drainage pipes 3.

[0031] Therefore, by setting the prefabricated water supply pipe 2 and drainage pipe 3, and using the vertically arranged water supply connection section 4 and drainage connection section 5, there is no need to additionally connect the horizontal water supply and drainage pipes on-site. Only by realizing the longitudinal pipe connection through the inspection port 13 at the connection, the systematicness and integrity of the internal water supply and drainage system of the building box 1 can be ensured. Only simple connection work needs to be completed on-site, greatly saving labor costs, reducing on-site operations, and improving the assembly rate and construction efficiency of the modular building.

[0032] Embodiment 2:

[0033] As Figure 4 、 Figure 5 shown, a pipe connection system for a prefabricated building module box body further includes a fixing mechanism 8 for fixing the water supply pipe 2 and the drainage pipe 3, so as to strengthen the stability of the water supply pipe 2 and the drainage pipe 3 and realize the position adjustment of the water supply pipe 2 and the drainage pipe 3.

[0034] As Figure 4 、 Figure 5 shown, the fixing mechanism 8 includes a fixing frame 81, an adjusting plate 82, an adjusting rod 83, a fixing rod 84, a nut 85 and a spring 86. The fixing frame 81 is horizontally arranged in a U shape on the inner wall of the pipe well 11, the adjusting plate 82 is horizontally arranged on the surface of the fixing frame 81, the adjusting rod 83 is horizontally rotatably connected to both ends of the fixing frame 81 and is threadedly connected to both ends of the adjusting plate 82.

[0035] As Figure 4 、 Figure 5As shown, the fixing rod 84 is U-shaped and its two ends penetrate through the adjusting plate 82 and the fixing bracket 81. Strip-shaped holes 87 for the transverse sliding of the fixing rod 84 are provided on the adjusting plate 82 and the fixing bracket 81. Nuts 85 are threadedly connected to the two ends of the fixing rod 84. Springs 86 are sleeved on the two ends of the fixing rod 84 and are located between the nuts 85 and the fixing bracket 81.

[0036] Since the pipe assemblies between the upper and lower building boxes 1 are all connected by thread fitting, the thread fitting requires that the connection must be straight up and down. Otherwise, water leakage will occur due to unstable connection.

[0037] Therefore, during the connection of the pipe assemblies, the water supply pipe 2 and the drain pipe 3 pass through the space between the adjusting plate 82 and the fixing rod 84. Thus, the lateral sliding of the fixing rod 84 can be controlled by applying a lateral force, so that the fixing rod 84 slides within the strip-shaped hole 87 to achieve the adjustment of the lateral positions of the water supply pipe 2 and the drain pipe 3.

[0038] Then, the adjusting rod 83 can also be controlled to rotate clockwise. The adjusting rod 83 drives the adjusting plate 82 away from the fixing bracket 81. At this time, the adjusting plate 82 can push the water supply pipe 2 and the drain pipe 3 to move outwards. And since a spring 86 is provided at the tail end of the fixing rod 84, the fixing rod 84 can also slide outwards under the compression of the spring 86.

[0039] The specific embodiments are only explanations of the present invention and are not limitations thereof. Those skilled in the art can make modifications to the embodiments without creative contributions according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
