Description

Technical Field

[0001] The utility model belongs to the technical field of building design, in particular to an open space drainage structure. Background Art

[0002] In order to increase some space for getting close to nature and leisure interaction, high-rise office buildings currently tend to set up open spaces (including open terraces or rooftops, etc.) when designing. Wooden floors are laid, flowers and plants are planted, and some tables and chairs are set up in the open spaces so that office workers can take a short break in this space.

[0003] But just because the space is open, it either extends out of the building's outer wall or is set on the top floor of the building. In the rainy areas of the south, terraces are easily drenched by rain. Some terraces are not designed to consider drainage, so that rainwater accumulates on the terrace after rain and cannot be discharged. In daily life, it is usually added to the ground of these open spaces, such as the patent CN215563289U, "A new type of balcony drainage structure" discloses that a drainage sink hole is opened on the balcony floor and connected to the groove through a drainage pipeline. Since the drainage sink hole in this scheme is set in the middle of the balcony, and the accumulated water usually accumulates at the edge or corner of the balcony, the drainage effect of setting the drainage sink hole near the middle of the balcony is not good. Therefore, the above patent designs a pivot structure to drain the accumulated water at the edge. This design method will greatly increase the construction cost and has certain safety hazards. That is, during long-term use, the movable mechanism may age, loosen or fail. In this case, once a person stands on the cover plate near the outer balcony, he may fall into the first groove; therefore, the movable mechanism needs to be regularly repaired in the later stage, which increases labor and maintenance costs.

[0004] In addition, considering that water usually accumulates at the edge or corner of a building, floor drains are usually set on both sides of the building. Because there are usually beams on both sides of the building, the floor drain is usually set 15 cm away from the beam structure, which will reduce the drainage effect of the building and make the overall structure of the building less compact and beautiful; further, because the floor drain structure is located on both sides of the building, when laying the ground, it is necessary to design slopes in different directions near the floor drain for drainage. Once the tilt direction is laid incorrectly, it will cause a situation where drainage cannot be achieved, and it needs to be changed later, which consumes manpower and time.

[0005] To solve the above problems, patent CN211691258U, "A building terrace drainage system", proposes a feasible technical solution. Most of the existing technologies for terrace drainage, including this patent, have drainage ditches that are integrally formed with the main structure of the terrace. The overall width of the drainage ditch is relatively large, and the cover plate above the drainage ditch is easily damaged by being stepped on during use, which in turn affects the normal use of the drainage ditch, and affects its drainage effect and service life.

[0006] Designing an open space drainage structure is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0028] like Figures 1 to 3 As shown, the utility model discloses an open space drainage structure, which is arranged on the outside or top floor of an indoor space. Specifically, it includes a floor slab body 1 cast on the outside or top surface of the building body, and a gap 10 that runs through the thickness of the floor slab body 1 is opened near its outer edge. Specifically, the floor slab body 1 includes a plane portion 11 and an enclosure portion 12 that are perpendicular to each other. Among them, the enclosure portion 12 is located at the periphery of the plane portion 11. The upper surface of the enclosure portion 12 is higher than the plane portion 11, and the lower surface of the enclosure portion 12 is lower than the plane portion 11. It can be seen that a step structure is formed between the enclosure portion 12 and the plane portion 11 to limit the range of activities of the open space and play a protective role. Furthermore, the enclosure portion 12 is cast as shown. Figure 1 or Figure 2 The safety fence 121 shown in the figure reserves a gap for the floor main body 1 to facilitate the drainage of the accumulated water on the floor main body 1.

[0029] like Figure 2As shown, the gap 10 runs through the plane part 11. The plane part 11 includes an anti-slip layer 111, a cement mortar layer 112, a concrete layer 113, a waterproof layer 114, a slope layer 115 and a floor layer 116 from top to bottom. Among them, the anti-slip layer 111 to the slope layer 115 has an inclination of 3%±1%, and the height near the water inlet 21 of the drainage channel 2 is lower than the height near the inner side of the building body, so as to facilitate rapid drainage and not affect people's normal walking. Specifically, the minimum thickness of the slope layer 115 is preferably 20±5mm, that is, the thickness of the slope layer 115 near the water inlet 21 is 20±5mm. Further, the slope layer 115 is mixed with cement and mortar in a ratio of 1:3 to ensure that the materials prepared in this ratio are easy to be effectively constructed into the slope layer, and the slope layer is inclined in one direction, so the construction difficulty is reduced and the construction efficiency is improved to a certain extent.

[0030] The concrete layer 113, the waterproof layer 114 and the insulation layer 117 located on the lower surface of the floor layer 116 are provided with sealing grooves for placing the sealant 102 at their ends near the water inlet 21. The sealant 102 can fix the position of the water inlet 21 of the drainage channel 2.

[0031] The safety fence 121 includes the vertically arranged floor layer 116 , and the waterproof layer 114 , the thermal insulation layer 117 and the outer coating layer arranged on the outer periphery of the floor layer 116 .

[0032] Specifically, in the present application, the thickness of the anti-slip layer 111 is preferably designed to be 30±5mm. Furthermore, the top of the water inlet 21 is flush with the lower surface of the anti-slip layer 111, and the width of the gap 10 at the anti-slip layer 111 is smaller than the width of the water inlet 21, that is, the gap 10 on the anti-slip layer 111 is narrow at the top and wide at the bottom. The water inlet of the drainage channel 2 is set in the gap of the floor slab body 1; and the uppermost structure of the floor slab body structure 1 is designed to be narrow at the top and wide at the bottom, and the anti-slip layer 111 is located above the water inlet 21, the position of the water inlet 21 is limited and protected, and the water inlet 21 is effectively prevented from being deformed or damaged by force, thereby extending the service life of the drainage channel 2.

[0033] In the present application, the thickness of the cement mortar layer 112 is preferably 20±5 mm. Furthermore, the cement mortar layer 112 is preferably made of dry hard cement and mortar in a ratio of 1:3, and a construction adhesive is added therein, so that the cement mortar layer 112 has a higher adhesion and is easier to construct. The thickness of the concrete layer 113 is 40±5 mm, and is made of fine stone concrete and a single-layer bidirectional steel mesh. Adding a steel mesh to fine stone concrete can increase its strength and adhesion, and improve its bearing capacity.

[0034] The waterproof layer 114 includes a 3mm thick asphalt waterproofing coil and a 2mm thick asphalt waterproofing coating. The two layers of waterproofing materials enhance the waterproofness of the floor slab body, effectively preventing water leakage or water seepage from the floor slab body. The surroundings and the root of the pipe of the waterproof layer 114 are folded upward, and the folding height is not less than 250±10mm, so that the floor slab body is waterproof and moisture-proof in all directions, extending its service life.

[0035] Furthermore, in the present application, it is preferred that an insulation layer 117 is provided on the upper and lower surfaces of the floor layer 116. The insulation layer 117 can reduce energy waste and increase the service life of the building body.

[0036] A water inlet 21 of a drainage channel 2 is arranged in the slit 10, that is, the maximum width of the slit 10 is equivalent to the width of the water inlet 21. Specifically, the width of the water inlet 21 is preferably 30±5 mm, and a drainage grate 22 is arranged at the top thereof. The drainage grate 22 guides the accumulated water to ensure that the accumulated water can effectively enter the drainage channel 2 after passing through the slit 10 for uniform drainage.

[0037] Furthermore, the main part of the drainage channel 2 is fixed to the lower surface of the floor body 1, and the water outlet of the drainage channel 2 is located at the end of the main part thereof and is connected to the drainage pipeline on the building body. Figure 2 As shown, the main part of the drainage channel 2 is placed in the drainage bracket 3, and the drainage bracket 3 is fixedly connected to the floor main body 1 by rivets; and an angle steel 103 is also provided between the bottom of the drainage bracket 3 and the enclosure 12. The main position of the drainage channel 2 is limited by the drainage bracket 3, and the overall position of the drainage channel 2 can be effectively fixed by the sealant 102. The angle steel 103 can enhance the connection stability between the drainage bracket 3 and the floor main body, thereby ensuring the installation stability of the drainage channel 2.

[0038] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
