Description

Technical Field

[0001] The utility model relates to the field of municipal housing construction, and more specifically, to a roof drainage structure. Background Art

[0002] Roof drainage is generally required on existing houses because roof drainage can effectively direct precipitation into gutters around the building, preventing water from penetrating into the building.

[0003] Existing roofs are generally inclined. The moisture on the roof falls along the inclined roof and then falls into the gutter. The gutter guides the rainwater to the downpipe, and then the downpipe transmits the rainwater to the ground. The drainage function of the roof is realized through the above process.

[0004] Because the existing roof is large in area, the garbage and leaves that fall on the roof are also relatively large. On rainy days, rainwater will carry the garbage and leaves into the gutter. When there are a lot of leaves and garbage accumulated, it is easy to affect the drainage efficiency of the downpipe. Therefore, the garbage and leaves in the gutter need to be cleaned regularly. However, the gutter has a certain depth. If leaves and garbage fall in the gutter for a long time, they will adhere to the bottom wall of the gutter, resulting in a long cleaning time.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Roof drainage structures, such as Figure 1 , Figure 2 and Figure 4As shown, it includes a drainage ditch 1 and a downpipe 2. The drainage ditch 1 is arranged in a rectangular shape as a whole. A drainage port 3 connected to the downpipe 2 is opened on the bottom wall of the drainage ditch 1. A permeable cloth 4 is arranged in the drainage ditch 1. The permeable cloth 4 is used to fit with each inner wall of the drainage ditch 1. A plurality of threaded holes 5 are opened on the top surface of the drainage ditch 1. A plurality of fixing rings 6 are installed on the permeable cloth 4. The permeable cloth 4 is fixed to the drainage ditch 1 by butterfly bolts 7. The butterfly bolts 7 pass through the fixing rings 6 and are threadedly connected in the threaded holes 5. A mesh portion 8 is arranged on the permeable cloth 4. The mesh portion 8 is used to cover the drainage port 3. In this embodiment, the number of threaded holes 5 is four. The four threaded holes 5 are respectively arranged near the four corners of the drainage ditch 1. The number of permeable cloths 4 matched with one drainage ditch 1 is two. People fix the permeable cloth 4 in the drainage ditch 1 by butterfly bolts 7 so that the permeable cloth 4 fits with the bottom wall of the drainage ditch 1. The threaded holes 5 are arranged on the top surface of the drainage ditch 1 so that The space around the butterfly bolt 7 is large, which makes it easy for people to unscrew or tighten the butterfly bolt 7, thereby realizing the disassembly and installation of the water-permeable cloth 4. When the water-permeable cloth 4 is installed in the drain, the mesh part 8 covers the drain port 3. People punch holes in the water-permeable cloth 4 to realize the opening of the mesh part 8. The arrangement of the mesh makes the water permeable area of ​​the mesh part 8 large, so that water can easily enter the drain port 3 through the mesh part 8. When there are many leaves and garbage in the drain ditch 1, people remove all the butterfly bolts 7 and take the water-permeable cloth 4 out of the drain ditch 1. In the process of taking out the water-permeable cloth 4, ensure that the garbage is wrapped in the water-permeable cloth 4, and then install another clean water-permeable cloth 4 on the drain ditch 1. This arrangement makes it difficult for garbage and leaves to adhere to the bottom wall of the drain ditch 1 and all garbage and leaves can be taken out of the drain ditch 1 at one time, which improves the speed of people cleaning the drain ditch 1 and ensures the cleanliness of the drain ditch 1.

[0021] like Figure 2 and Figure 3As shown, a groove 9 is provided on the bottom wall of the drainage ditch 1, and the groove 9 is arranged along the length direction of the drainage ditch 1. The drain port 3 is arranged on the bottom of the groove 9. Because the water-permeable cloth 4 can allow water to pass through, the water in the drainage ditch 1 can enter the groove 9 through the water-permeable cloth 4, and then flow into the drain port 3, thereby ensuring the drainage efficiency of the drain port 3. A plurality of square grooves 10 are also provided on the bottom wall of the drainage ditch 1, both of which are located on both sides of the groove 9. A plurality of counterweights 11 for embedding in the square grooves 10 are fixedly connected to one side of the water-permeable cloth 4. The thickness of the square groove 10 is equal to the thickness of the counterweight 11. The counterweight 11 is heavier, so that the water-permeable cloth 4 can fit the bottom wall of the drainage ditch 1 under the action of the gravity of the counterweight 11. At the same time, the cooperation of the square grooves 10 and the counterweight 11 can provide a positioning effect for the mesh portion 8. After all the counterweights 11 are embedded in the corresponding square grooves 10, the mesh portion 8 is aligned with the drain port 3, which makes it convenient for people to install the permeable cloth 4. The number of square grooves 10 and counterweights 11 is four, and the four square grooves 10 are respectively arranged near the four corners of the drain ditch 1, so that the fitting area between the permeable cloth 4 and the bottom surface of the drain ditch 1 is larger. The mesh portion 8 is arranged in a circular shape and the diameter of the mesh portion 8 is at least twice the diameter of the drain port 3. In this embodiment, the diameter of the mesh portion 8 is twice the diameter of the drain port 3, so that the difficulty of aligning the drain port 3 and the mesh portion 8 is reduced and the area of ​​the mesh portion 8 is not large, which reduces the difficulty of production. The permeable cloth 4 is woven with nylon fibers, which have the characteristics of high strength, thereby ensuring the overall strength and life of the permeable cloth 4.
