Description

Technical Field

[0001] The utility model relates to the technical field of building drainage, in particular to an anti-blocking drainage building water supply and drainage pipe which is easy to install. Background Art

[0002] Stairs are widely used as a common tool to connect the upper and lower floors. Stairs include indoor stairs and outdoor stairs. The drainage at the outdoor stair ramp is often irregular. When draining, it flows everywhere from the upper end to the lower end of the ramp, resulting in water accumulation in some places and dampness in the wall skirt. This is a common drainage problem. Therefore, it is necessary to use a drainage structure to effectively drain the building stairs. However, the existing building stair drainage structure still has certain defects during use.

[0003] For example, a drainage structure of an underground evacuation staircase proposed in application number CN202020429957.9 includes a ground surface, a staircase for connecting the ground surface and a sunken plaza, the staircase includes a first step group and a second step group connected in sequence from top to bottom, the first step group and the second step group both include permeable step plates, a platform plate is provided at the connection between the first step group and the second step group, the width of the platform plate is greater than the width of the step plate, a green belt located on the ground is provided on one side of the staircase, a drainage trough is provided at the lower end of the step plate of the first step group, and a drainage trough is connected to the end of the green belt on the ground next to it at one end. A pipe is provided on the side of the first step group near the drain pipe along the direction of the stairs. The drain pipe is connected to the drain pipe, and the drain pipe leads to the underground water tank in the green belt or the municipal pipeline on the ground. In actual use, the drainage structure of the underground evacuation stairs stores the collected rainwater in the underground water tank through the rainwater collection port and the water guide trough as well as the drain pipe and the drain pipe. However, it is not convenient to collect the rainwater on the steps thoroughly by collecting only through the rainwater collection port, which easily causes rainwater to remain on the surface of the steps. At the same time, when siltation occurs inside the drain pipe and the water pipe, it is not convenient to disassemble and dredge the water.

[0004] Therefore, we propose an easy-to-install anti-blocking drainage building water supply and drainage pipe to solve the above-mentioned problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The utility model provides a technical solution: an anti-blocking drainage building water supply and drainage pipe that is easy to install, comprising an intermediate ramp 1, the surface of the intermediate ramp 1 is provided with diversion grooves 2 at equal intervals, the diversion grooves 2 are inclined from the middle to both ends, stair treads 3 are fixedly installed on both sides of the intermediate ramp 1, the side of the stair tread 3 close to the intermediate ramp 1 is provided with drainage grooves 4, the surface of the stair tread 3 is inclined toward the drainage grooves 4, the bottom ends of the intermediate ramp 1 and the stair tread 3 are fixedly connected with a floor platform 5, and the surface of the floor platform 5 is provided with drainage grooves 6;

[0030] The design of the above structure enables that when there is rainwater on the middle ramp 1, the equally spaced guide grooves 2 can effectively throttle and guide the rainwater, and guide the collected rainwater into the interior of the drainage grooves 4 on both sides. When there is rainwater on the surface of the stair treads 3, combined with the oblique setting of the drainage grooves 4, the oblique setting of the surface of the stair treads 3 can guide the rainwater into the interior of the drainage grooves 4, and then the drainage grooves 4 will guide the collected rainwater layer by layer into the interior of the drainage grooves 6, and the rainwater inside the drainage grooves 6 will be filtered by the filter plates 9 and enter the interior of the drainage riser 8 to be discharged, thereby improving the drainage effect of the water supply and drainage pipeline.

[0031] A mounting groove 7 is provided at a right angle to the drainage groove 6. A drainage riser 8 is movably connected to the interior of the mounting groove 7. A filter plate 9 is fitted on the top of the mounting groove 7. The drainage riser 8 is connected to the bottom surface of the floor platform 5 by a sealing docking mechanism. The sealing docking mechanism includes a bottom plate 10 fixedly sleeved on the outer ring of the top of the drainage riser 8. A sealing strip 11 is fixedly installed on the top surface of the bottom plate 10. A sealing groove 12 is provided on the bottom surface of the floor platform 5. The size of the sealing strip 11 matches the size of the sealing groove 12. The bottom plate 10 forms a sealing structure with the sealing groove 12 through the sealing strip 11.

[0032] The design of the above structure enables that when the drainage riser 8 is inserted into the interior of the installation groove 7, the top surface of the base plate 10 will be fitted with the bottom surface of the floor platform 5, and the sealing strip 11 on the top surface of the base plate 10 will be matched with the sealing groove 12 opened on the bottom surface of the floor platform 5. Such a staggered connection can prevent leakage from the gap between the drainage riser 8 and the installation groove 7, thereby improving the installation sealing effect of the water supply and drainage pipe of the anti-blocking drainage building.

[0033] The drainage riser 8 is connected to the floor platform 5 through a quick disassembly and assembly mechanism. The quick disassembly and assembly mechanism includes a limit seat 13 installed at equal angles on the bottom surface of the base plate 10 and the outer circle of the top of the drainage riser 8.

The clamping block 16 is movably engaged with the clamping groove 19;

[0034] The design of the above structure ensures that when the drainage riser 8 is inserted into the interior of the installation groove 7, the clamping block 16 will also be inserted into the interior of the clamping groove 19, and then the spring 18 will push the clamping block 16 to engage with the clamping groove 19, thereby completing the fixed connection between the drainage riser 8 and the floor platform 5. When the drainage riser 8 is clogged by siltation, the clamping block 16 can be pulled to make the clamping block 16 cooperate with the through hole 17 to slide on the fixing rod 15, and cooperate with the limiting groove 14 to slide inside the limiting seat 13 until the clamping block 16 is separated from the clamping groove 19. Then the connection between the drainage riser 8 and the floor platform 5 can be released, and the drainage riser 8 can be disassembled and the internal dredging work can be realized, thereby improving the convenience of disassembly and assembly of the drainage riser 8.
