Description

Technical Field

[0001] The present application relates to the technical field of roof waterproofing, and in particular to a roof waterproofing structure of a high-rise building. Background Art

[0002] Roof waterproofing is an important building maintenance task that protects the building from moisture damage, thereby extending the service life of the building.

[0003] At present, the waterproofing of high-rise buildings generally uses waterproof membranes and waterproof coatings on the concrete base of the roof, and finally applies a layer of concrete to achieve a waterproof effect. At the same time, for drainage, the surface of the concrete layer is generally set with a certain inclination; however, in order to facilitate walking, the inclination is generally low. When it rains, rainwater will gather on the concrete base under the protection of the surrounding parapets, making it easy to penetrate. Rainwater gathers on the roof, which will affect the life of the waterproof material, thereby reducing the effect of the waterproof membrane and causing leakage on the roof. Utility Model Content

[0004] In order to reduce the possibility of rainwater gathering on the roof and improve the waterproof effect of the roof, the present application provides a waterproof structure for the roof of a high-rise building.

[0005] The present application provides a waterproof structure for the roof of a high-rise building, which adopts the following technical solution:

[0007] By adopting the above technical solution, the water-conducting layer is inclined, which can quickly guide rainwater from the roof to the drainage ditch and discharge it, avoiding damage to the roof caused by accumulated water and causing failure of the waterproof material, thereby ensuring the waterproof performance of the roof structure; at the same time, an active layer is set on the water-conducting layer, so that the roof has not only a waterproof function, but also a function for people to walk on, thereby improving the utilization rate and convenience of the roof.

[0008] Optionally, the water guide plate includes a plurality of water guide bars and waterproof bars disposed between two adjacent water guide bars. A water guide groove is formed on the upper surface of the water guide bar and penetrates to one end away from the water guide plate. The side walls of two adjacent water guide bars are in mutual abutment. A connection groove for inserting the upper edge portions of two adjacent water guide bars is formed on the lower surface of the waterproof bar. A connecting member for connecting the water guide bar and the waterproof bar is provided on the waterproof bar.

[0009] By adopting the above technical solution, the design of the water guide groove on the upper surface of the water guide bar can quickly guide the water flow to one end away from the water guide plate, improving the drainage efficiency. At the same time, the side walls of adjacent water guide bars are in mutual abutment, and a waterproof bar is provided. A connection groove is formed on the lower surface of the waterproof bar, so that the upper edge portions of two adjacent water guide bars can be inserted therein, thereby enhancing the overall waterproof performance of the water guide plate. This design can effectively prevent moisture from seeping in through the gaps between the water guide bars, improving the waterproof effect.

[0010] Optionally, the connecting member is a connecting bolt and a connecting nut. The connecting nut can pass through the lower end of the water guide bar and the upper end portion of the waterproof bar and is threadedly connected to the connecting nut.

[0011] By adopting the above technical solution, the threaded connection of the connecting bolt and the connecting nut can achieve the tight connection between the water guide bar and the waterproof bar, ensuring the stability and reliability of the connection. At the same time, this connection method is detachable, facilitating later maintenance and replacement. When the water guide bar or the waterproof bar is damaged, the connecting bolt and the connecting nut can be conveniently disassembled for local replacement, reducing the maintenance cost and difficulty.

[0012] Optionally, mounting bars are provided at the ends of the water guide bars close to the positioning plate. Mounting grooves for inserting the mounting bars are formed on the side walls on both sides of the positioning plate. The fixing member can limit the mounting bars from sliding out of the mounting grooves.

[0013] By adopting the above technical solution, mounting bars are provided at the ends of the water guide bars close to the positioning plate, and mounting grooves for inserting the mounting bars are formed on the side walls on both sides of the positioning plate, which can achieve the quick positioning and installation of the water guide bars. This design simplifies the installation steps and improves the installation efficiency.

[0014] Optionally, the fixing member is a fixing bolt, and the fixing bolt can threadedly pass through the positioning plate and the mounting bar.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0033] An embodiment of the present application discloses a waterproof structure for the roof of a high-rise building. Referring to Figure 1 and Figure 2 , the waterproof structure includes a concrete base 1 and a parapet wall 2 fixedly arranged above the concrete base 1. The parapet wall 2 is arranged along the circumferential direction of the concrete base 1. Among them, waterproof materials can be arranged in the concrete base 1 for waterproofing. At the same time, the waterproof structure further includes a water guide layer 3 arranged above the concrete base 1, a movable layer 4 arranged above the water guide layer 3, and drainage grooves 5 arranged on two parallel sides outside the parapet wall 2 and a drainage device 6 for draining the drainage grooves 5. The uppermost movable layer 4 is used for shaping or erecting equipment. Rainwater can pass through the movable layer 4 and enter the water guide layer 3, and is discharged into the drainage grooves 5 under the guidance of the water guide layer 3, so that rainwater can be drained in time on rainy days, reducing the possibility of water leakage caused by rainwater accumulation.

[0034] Referring to Figure 2 and Figure 3 , in this embodiment, the water guide layer 3 includes a positioning plate 31, water guide plates 32 symmetrically connected to both sides of the positioning plate 31, and a fixing member 33 for fixing the water guide plates 32 on the positioning plate 31. The water guide plates 32 on both sides are inclined, with the positioning plate 31 as the highest point, and extend obliquely downward along the direction away from the positioning plate 31. Relief grooves 21 for passing the water guide plates 32 are formed on two parallel side walls of the parapet wall 2, so that the two ends of the two water guide plates 32 away from each other can pass through the relief grooves 21 and extend above the drainage grooves 5 for drainage.

[0035] Referring to Figure 2 and Figure 4 , Further, the water guide plate 32 includes a plurality of water guide strips 321 and a plurality of waterproof strips 322 disposed between adjacent two water guide strips 321. Both the water guide strips 321 and the waterproof strips 322 can be rectangular strips. Among them, a water guide groove 323 for water flow to pass through is formed on the upper surface of the water guide strip 321, and the water guide groove 323 extends along the length direction of the water guide strip 321 and penetrates to one end surface facing away from the water guide plate 32. Thus, the cross-section of the water guide strip 321 is in a "concave" shape. A connecting groove 324 is formed on the lower surface of the waterproof strip 322. The upper edge portions of adjacent two water guide strips 321 can be jointly inserted into the connecting groove 324, that is, the waterproof strip 322 can be buckled on the two water guide strips 321 to seal the abutting surface formed between the side walls of the two water guide strips 321 in contact with each other, restricting rainwater from passing through the water guide plate 32.

[0036] Referring to Figure 2 and Figure 4 , In this embodiment, a connecting member 7 for connecting the water guide strip 321 and the waterproof strip 322 is provided on the waterproof strip 322. Specifically, the connecting member 7 can be a connecting bolt 71 and a connecting nut 72. The connecting bolt 71 can penetrate into the upper edge portions of the waterproof strip 322 and adjacent two water guide strips 321 from one side, pass through the other side of the waterproof strip 322, and be threadedly connected with the connecting nut 72. In order to increase the waterproof property, elastic gaskets can be provided between the head of the connecting bolt 71 and the side wall of the water guide strip 321, and between the connecting nut 72 and the other side wall of the water guide strip 321, so as to increase the stability of the connection part and improve the waterproof property. Further, a plurality of connecting members 7 can be arranged at intervals along the length direction of the water guide strip 321, thereby strengthening the connection stability between the water guide strip 321 and the waterproof strip 322.

[0037] Referring to Figure 3 and Figure 5 , In this embodiment, the positioning plate 31 is a rectangular plate. An installation strip 325 can be integrally formed at one end of the water guide strip 321 close to the positioning plate 31. The cross-section of the installation strip 325 is rectangular. When the water guide strip 321 is arranged obliquely at a certain angle, the installation strip 325 can be in a horizontal state. An installation groove 311 for inserting the installation strip 325 is formed on the side wall of the positioning plate 31. The installation groove 311 extends along the length direction of the positioning plate 31 and is respectively arranged on both sides of the positioning plate 31, so that the installation strips 325 on all the water guide strips 321 can be inserted into the installation groove 311.

[0038] Referring to Figure 3 and Figure 5, in this embodiment, the fixing member 33 is a fixing bolt 331. When the installation strip 325 is inserted into the installation groove 311, the fixing bolt 331 can pass through the positioning plate 31 and the installation strip 325 from top to bottom, and is threadedly connected to a part of the positioning plate 31 below the installation groove 311, so as to be able to limit the installation strip 325 from disengaging from the installation groove 311, and fixedly connect the water guide strip 321 to the positioning strip. Thus, when rainwater passes through the movable layer 4, the rainwater falling on the positioning plate 31 can fall along both sides onto the water guide strip 321 and be discharged along the water guide strip 321.

[0039] Refer to Figure 3 and Figure 5 , in this embodiment, both the positioning plate 31 and the water guide plate 32 can be made of materials such as aluminum or steel to facilitate installation and maintenance. The waterproof structure further includes a support frame 8 for supporting the water guide layer 3. Specifically, the support frame 8 can include a plurality of vertical support rods 81 fixedly arranged on the concrete base layer 1 along the vertical direction, a support seat 82 welded and fixed to the upper ends of the vertical support rods 81, and a horizontal support rod 83 fixed between the vertical support rods 81. Among them, a plurality of vertical support rods 81 are arranged in an array along the length direction of the positioning plate 31 and the length direction of the water guide strip 321, and the vertical support rods 81 gradually increase in length along the direction close to the positioning plate 31. The horizontal support rod 83 is fixed between two adjacent vertical support rods 81 to enhance the stability of the vertical support rods 81. The lower surface of the support seat 82 is welded to the vertical support rod 81, and the upper end is in an inclined plane, so as to be able to increase the contact area with the lower surface of the water guide strip 321 and improve the support effect.

[0040] Refer to Figure 1 and Figure 2 , in this embodiment, the movable layer 4 includes a plurality of movable plates 41 arranged in parallel to each other. The movable plates 41 are rectangular plates, and there is a gap between two adjacent movable plates 41. Thus, rainwater can fall along the gap between the sliding plates onto the upper part of the water guide layer 3 to avoid water accumulation on the movable plates 41 and facilitate activities on the movable plates 41. To facilitate the installation of the movable plates 41, positioning rings 22 can be fixed on the parapet wall 2. The positioning rings 22 extend circumferentially along the inner side wall of the parapet wall 2 to form a "hui" character shape. Both ends of the movable plates 41 can abut against the positioning rings 22, so as to be able to support the movable plates 41. At the same time, the movable plates 41 and the positioning rings 22 can be detachably connected by bolts, so as to facilitate the disassembly of the movable plates 41 for the maintenance of the water guide layer 3.

[0041] Refer to Figure 1 and Figure 2, in this embodiment, the drainage groove 5 extends along the length direction of the positioning plate 31. A water outlet 51 is formed in the bottom wall at one end of the drainage groove 5. A filter screen can be arranged at the position of the water outlet 51. The drainage device 6 can be a drainage pipe or other structures. The inner bottom wall of the drainage groove 5 can be inclined downward towards the water outlet 51, so that the rainwater falling from the water guide strip 321 into the water guide groove 323 can be discharged from the water outlet 51 along the inner bottom wall of the drainage groove 5.

[0042] The implementation principle of a waterproof structure for the roof of a high-rise building in an embodiment of the present application is as follows: The movable layer 4 is used for people to walk. When it rains, the rainwater can fall into the water guide layer 3 from the gaps between the movable plates 41, flow along the water guide groove 323 into the drainage groove 5, and finally be discharged through the drainage device 6.

[0043] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
