Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to an outdoor staircase structure with rapid drainage function. Background Technology
[0002] Most detached houses are equipped with open staircases during construction. However, during heavy rains, water easily accumulates on the stairs. If the water cannot be drained in time, the stair treads become slippery, posing a safety hazard to residents. In order to prevent slipping and maintain structural strength, staircases are designed with raised anti-slip grooves but do not have drainage design, making it even easier for water to accumulate on the stairs. Some existing staircases use drainage grooves designed on the steps for drainage. However, in order to ensure structural strength, the drainage grooves are often designed to be narrow and are prone to clogging after use, causing them to lose their drainage function. This needs to be improved. Utility Model Content
[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an outdoor staircase structure with rapid drainage function, including a stair beam and several stair steps. The stair steps are sequentially fixed on the stair beam. Several water collection grooves are formed on the surface of each stair step, and a connecting groove is formed between adjacent water collection grooves. The connecting grooves are all located at the same end of the water collection grooves. A pre-embedded drainage pipe is provided on the side wall of each stair step, and one end of the pre-embedded drainage pipe is connected to the water collection groove. A water flow guide channel is provided on the stair beam near the outlet of the pre-embedded drainage pipe. The water collection grooves are also equipped with anti-clogging cleaning devices.
[0004] Using the above technical solution, several water collection troughs are opened on the surface of several stair steps, and a connecting groove is opened between each pair of adjacent water collection troughs. Then, a pre-embedded drainage pipe connected to the water collection trough is installed on the side wall of the stair steps. In this way, the accumulated water can flow out through the water collection trough and then through the pre-embedded drainage pipe, flowing into the water flow guide channel and flowing to the ground along the water flow guide channel, avoiding the situation where the accumulated water is directly discharged and drips from the air. In addition, an anti-clogging cleaning device is installed in the water collection trough, which can quickly clean the water collection trough in time and avoid the situation where the water collection trough is blocked and cannot drain normally.
[0005] Further features of this invention: The anti-clogging cleaning device includes a mounting cover, a pair of mounting plates, and several scrapers that match the water collection troughs. On both sides of the water collection troughs at both ends of the several stair steps, there are mounting grooves that match the mounting cover. The positions of the mounting grooves correspond to the openings of the pre-embedded drainage pipes. On the side walls of the water collection troughs at both ends of the several water collection troughs, there are a pair of sliding grooves that match the mounting cover. The several scrapers are all mounted on the mounting cover and aligned with the several water collection troughs. The pair of mounting plates are detachably mounted above the mounting grooves.
[0006] By adopting the above technical solution, the anti-clogging cleaning device includes a mounting cover, a pair of mounting plates, and several scrapers that match the water collection tanks. On both sides of the water collection tanks at both ends of the stair treads, there are mounting grooves that match the mounting cover. The positions of the mounting grooves correspond to the openings of the pre-embedded drainage pipes. On the side walls of the water collection tanks at both ends of the several water collection tanks, there are a pair of sliding grooves that match the mounting cover. The several scrapers are all mounted on the mounting cover and aligned with the several water collection tanks. The pair of mounting plates can be detachably mounted above the mounting grooves. When not cleaning, the mounting cover protects the openings of the pre-embedded drainage pipes. When cleaning, simply push the mounting cover to move it along the direction of the water collection tank, and the scrapers can scrape off the dirt in the water collection tank, preventing clogging.
[0007] A further feature of this invention is that a push block is provided on the mounting cover.
[0008] By adopting the above technical solution, since the mounting cover is also provided with a push block, the mounting cover can be pushed more conveniently.
[0009] A further feature of this invention is that a filter screen is provided on one end opening of the pre-embedded drainage pipe located in the water collection tank.
[0010] By adopting the above technical solution, since a filter screen is provided on one end opening of the pre-buried drainage pipe located in the water collection tank, dirt can be further prevented from clogging the pipe opening of the pre-buried drainage pipe. Attached Figure Description

Detailed Implementation
[0014] like Figure 1-2As shown, an outdoor staircase structure with rapid drainage function includes a stair beam 1 and several stair steps 2. The stair steps are fixedly installed on the stair beam in sequence. Several water collection grooves 3 are opened on the surface of each stair step. A connecting groove 4 is opened between two adjacent water collection grooves. The connecting grooves are all located at the same end of the water collection grooves. A pre-embedded drainage pipe 5 is provided on the side wall of each stair step. One end of the pre-embedded drainage pipe is connected to the water collection groove. A water flow guide channel 6 is provided on the stair beam near the outlet of the pre-drainage pipe. An anti-clogging cleaning device 7 is also provided on the water collection grooves.
[0015] Several water collection troughs are made on the surface of several stair steps, and a connecting groove is made between each pair of adjacent water collection troughs. Then, a pre-embedded drainage pipe connected to the water collection troughs is installed on the side wall of the stair steps. In this way, the water can flow out through the water collection troughs and then through the pre-embedded drainage pipes, flowing into the water flow guide channel and flowing to the ground along the water flow guide channel, avoiding the situation where the water is directly discharged and drips from the air. In addition, an anti-clogging cleaning device is installed in the water collection troughs to quickly clean the water collection troughs in time and avoid the situation where the water collection troughs are blocked and cannot drain normally.
[0016] The anti-clogging cleaning device includes a mounting cover 8, a pair of mounting plates 9, and several scrapers 10 that match the water collection troughs. On both sides of the water collection troughs at both ends of the several stair steps, there are mounting grooves 11 that match the mounting cover. The position of the mounting grooves corresponds to the opening of the pre-buried drainage pipe. On the side walls of the water collection troughs at both ends of the several water collection troughs, there are a pair of sliding grooves 12 that match the mounting cover. The several scrapers are all set on the mounting cover and their positions are aligned with the several water collection troughs. The pair of mounting plates can be detachably set above the mounting grooves.
