Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a corridor drainage structure. Background Art

[0002] Open corridors are mostly used to connect multiple buildings or a public space inside multiple buildings. They are usually a corridor or corridor system, which provides the functions of connection and passage, allowing people to move and communicate conveniently between buildings or inside buildings. In addition, the safety design of open corridors is also very important. In addition to meeting the requirements of passage, it is also necessary to meet the purpose of fire safety passages, and most of them are not closed. Therefore, on snowy and rainy days, rain and snow will drift into the corridor. If they are not discharged in time, there will be safety hazards. The existing corridor drainage method is to make ordinary floor drains, and the pipes are connected to the drainage riser from under the floor slab. This method has a drainage horizontal branch pipe under the floor slab, which is easy to be seen and affects the appearance. With the improvement of living standards, people have higher and higher requirements for building quality. The corridor drainage riser is easy to be enclosed with brick walls or decoration materials, but the drainage horizontal branch pipe is difficult to hide, which affects the neatness of the overall building facade. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a novel corridor drainage structure, which adopts drainage riser to cut off the flow to the annular floor drain for drainage, thus avoiding the need to set drainage lateral branch pipes under the corridor floor and improving the quality of the facade.

[0004] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0005] A corridor drainage structure comprises an open corridor, wherein drainage risers connected in sequence are arranged between the open corridor floors, the drainage risers are concentric reducers, the large ends of the concentric reducers penetrate the corridor floors, the small ends of the concentric reducers are connected to the large ends of the concentric reducers of the corridor floors of the next layer, and the drainage risers are located on either outer side of the corridor floors.

[0006] Furthermore, the concentric reducer is a galvanized steel pipe.

[0007] Furthermore, a rain gutter is provided at the large end of the drainage riser of the top corridor floor in the open corridor, and the rain gutter is used to collect the accumulated water of the top corridor floor into the drainage riser.

[0008] Furthermore, the large end of the drainage riser of the middle-layer corridor floor in the open corridor is plugged into the small end and tail of the drainage riser of the upper-layer corridor floor, and the small end and tail of the drainage riser of the upper-layer corridor floor is provided with an annular floor drain, which is located between the large end and the small end, and the top of the annular floor drain is flush with the large end of the drainage riser, and the annular floor drain is used to collect the accumulated water on the middle-layer corridor floor into the drainage riser.

[0009] Furthermore, the tail of the small end of the drainage riser of the bottom corridor floor in the open corridor is connected to the drainage elbow.

[0010] Furthermore, a waterproof pipe sleeve is arranged outside the large end of the drainage riser penetrating the corridor floor, and both ends of the waterproof pipe sleeve are flush with the thickness of the corridor floor.

[0011] Furthermore, the two ends of the waterproof pipe sleeve and the adjacent parts of the corridor floor are sealed with weather-resistant glue.

[0012] Furthermore, a drainage ditch is arranged on any outer side of the corridor floor, and the drainage riser passes through the drainage ditch and is connected layer by layer.

[0013] Furthermore, a slope leveling layer is provided on the surface of the corridor floor, and the slope leveling layer is inclined toward the drainage riser.

[0014] Furthermore, a slope leveling layer is arranged on the surface of the drainage ditch, and the slope leveling layer is inclined toward the drainage riser.

[0015] The benefit of the utility model lies in that, compared with the existing corridor drainage structure, the utility model avoids the arrangement of drainage horizontal branches under the floor slab, and the position of the drainage riser can be flexibly arranged according to the requirements of the facade. The riser is made of metal materials such as steel pipes, which can make the facade more metallic, and can discharge the water accumulated in the corridor in time while taking into account the aesthetics. It can be used in projects with relatively high requirements for the appearance of the facade. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] like Figures 1 to 3 A corridor drainage structure shown includes an open corridor, wherein the open corridor floor 1 is provided with drainage risers 2 connected in sequence, wherein the drainage risers 2 are concentric reducers, wherein the large end 21 of the concentric reducers penetrates the corridor floor 1, and the small end 22 of the concentric reducers is connected to the large end 21 of the concentric reducers of the corridor floor 1 of the next layer, and the drainage risers 2 are located at any outer side of the corridor floor 1. The corridor drainage structure of the utility model is provided with drainage risers at any outer side of the corridor floor, and concentric reducers are used to connect the drainage risers of each floor in sequence, replacing the method of connecting the drainage horizontal branch pipes and the drainage risers in layers in the prior art, so that the overall facade of the building is more beautiful and neat. Furthermore, the concentric reducers are galvanized steel pipes, which can make the facade of the building more metallic, and can both drain the water accumulated in the corridor in time and take into account the aesthetics.

[0024] In one embodiment, a rain gutter 3 is provided at the end of the big head 21 of the drainage riser of the top corridor floor 1 in the open corridor, and the rain gutter 3 is used to collect the accumulated water of the top corridor floor into the drainage riser 2. The big head 21 end of the drainage riser of the middle corridor floor 1 in the open corridor is plugged with the tail of the small head 22 of the drainage riser of the upper corridor floor 1, and the tail of the small head 22 of the drainage riser of the upper corridor floor 1 is sleeved with an annular floor drain 4, which is located between the big head 21 end and the tail of the small head 22, and the top of the annular floor drain 4 is flush with the big head 21 end of the drainage riser, and the annular floor drain 4 is used to collect the accumulated water of the middle corridor floor into the drainage riser 1. The tail of the small head 22 of the drainage riser of the bottom corridor floor 1 in the open corridor is connected to the drainage elbow 5. In this way, a complete vertical drainage system is formed through the drainage risers on each floor, the rain gutters on the top floor, the annular floor drains on the middle floor and the drainage elbows on the bottom floor to drain the accumulated water on each floor of the corridor out of the building.

[0025] In one embodiment, a waterproof sleeve 6 is disposed outside the large end 21 of the drainage riser that passes through the corridor floor 1, and the two ends of the waterproof sleeve 6 are flush with the thickness of the corridor floor 1. The two ends of the waterproof sleeve 6 are sealed with weather-resistant glue 7 at the junction with the corridor floor 1. Since the large end of the drainage riser will pass through the corridor floor, a gap will be formed between the drainage riser and the corridor floor, and rainwater will penetrate into the corridor floor along the outside of the drainage riser, destroying the corridor structure and service life. Therefore, a waterproof sleeve is disposed between the drainage riser and the corridor floor, and the two ends of the waterproof sleeve are sealed with weather-resistant glue, which further prevents rainwater from entering the building wall and eroding.

[0026] In one embodiment, a drainage ditch 8 is provided on any outer side of the corridor floor, and the drainage riser 2 penetrates the drainage ditch 8 and is connected layer by layer. That is, the drainage riser is arranged in the drainage ditch, and a slope layer 9 is provided on the surface of the corridor floor, and the slope layer 9 is inclined toward the drainage ditch and the drainage riser. At the same time, a slope layer can also be provided on the surface of the drainage ditch 8, and the slope layer is inclined toward the drainage riser 2. Of course, in an embodiment where a drainage ditch is not provided, a slope layer is also provided on the corridor floor, and the slope layer is inclined toward the drainage riser. The provision of drainage ditches and slope layers is to better discharge the accumulated water in the corridor floor out of the building.

[0027] The corridor drainage structure of the utility model avoids the arrangement of drainage horizontal branch pipes under the floor slab. The position of the drainage vertical pipe can be flexibly set according to the requirements of the facade. The vertical pipe can be made of metal materials such as steel pipes to make the facade more metallic, which can not only drain the water accumulated in the corridor in time, but also take into account the aesthetics.
