[0033] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.
[0034] The following describes the high-low span drainage structure of the present application with reference to the accompanying drawings.
[0035] High-low span: refers to the structure of the building in different areas with height difference, wherein the relatively higher part is the high span part, and the relatively lower part is the low span part.
[0036] The high span part 3 and the low span part 4 in the specific embodiment of the present application are arranged adjacent to each other, and the high-low span joint 9 is formed between the high span part 3 and the low span part 4.
[0037] As shown in Figure 1 and Figure 2 The specific embodiment of the present disclosure provides a high-low span drainage structure, which comprises a first drainage plate 1, a second drainage plate 2 and a drainage channel, wherein the first drainage plate 1 is arranged on the top surface of the structural layer of the high span part 3, and the first drainage plate 1 extends to the vertical surface of the structural layer of the high span part 3; the second drainage plate 2 is arranged on the vertical surface of the structural layer of the high span part 3, and the second drainage plate 2 is sealingly connected with the first drainage plate 1; the drainage channel is formed on the low span part 4.
[0038] Specifically, the laying of the drainage board in the existing construction only focuses on the plane drainage, and lacks the vertical drainage guiding measures. For the high-low span, although the water in the high span part 3 can be guided from the inside to the outside of the plane drainage structure to the vertical surface of the structural layer, the water seeping to the vertical surface of the structural layer will accumulate at the high-low span junction 9 and cannot be effectively guided to the drainage channel. In other words, the high span part 3 and the drainage channel cannot form a closed drainage measure, thereby causing the leakage problem at the high-low span junction 9. In the present disclosure, the first drainage board 1 is arranged on the top surface of the structural layer of the high span part 3 as a plane drainage structure, and the second drainage board 2 is arranged on the vertical surface of the structural layer of the high span part 3 as a vertical drainage structure. The first drainage board 1 and the second drainage board 2 are sealingly connected to form a closed drainage path, so that the water is guided into the drainage channel through the drainage path, thereby solving the leakage problem at the high-low span junction 9.
[0039] As shown in Figure 2 and Figure 3 In some embodiments, the high span part 3 includes a structural layer and a protective layer, the first drainage board 1 is arranged on the top surface of the structural layer of the high span part 3, and the protective layer covers the first drainage board 1. The convex surface of the first drainage board 1 is downwardly arranged adjacent to the top surface of the structural layer of the high span part 3, and the concave surface of the first drainage board 1 is upwardly arranged adjacent to the bottom surface of the protective layer of the high span part 3. The second drainage board 2 is arranged on the vertical surface of the structural layer of the high span part 3, the concave surface of the second drainage board 2 is leftward, and the convex surface of the second drainage board 2 is rightward arranged adjacent to the vertical surface of the structural layer of the high span part 3. The drainage gaps between the drainage protrusions of the second drainage board 2 and the drainage gaps between the drainage protrusions of the first drainage board 1 are in communication with each other to form a drainage path.
[0040] As shown in Figure 2 and Figure 3 To ensure the closure of the drainage path, it is necessary to avoid the gap between the first drainage board 1 and the second drainage board 2, and then it is necessary to improve the sealing connection quality between the first drainage board 1 and the second drainage board 2. In some embodiments, the second drainage board 2 and the first drainage board 1 adopt L-shaped lap joint.
[0041] Specifically, the end parts of the second drainage board 2 and the first drainage board 1 which need to be sealingly connected are lap-jointed in a right angle form to form a stable L-shaped structure 10, so that the second drainage board 2 and the first drainage board 1 are more closely fitted, thereby improving the sealing connection quality.
[0042] It should be noted that the specific construction method of L-shaped lap joint is known to those skilled in the art, and specifically, the second drainage plate 2 can be located outside the first drainage plate 1, or the first drainage plate 1 can be located outside the second drainage plate 2. Since the water flow direction is from the high-span part to the low-span part, i.e. the water flows from below the first drainage plate 1 to the second drainage plate 2, it is preferred that the second drainage plate 2 is located outside the first drainage plate 1, i.e. the lap joint of the second drainage plate 2 and the first drainage plate 1 at the top surface of the structural layer is located above the first drainage plate 1, and the lap joint of the second drainage plate 2 and the first drainage plate 1 at the vertical surface of the structural layer is downward, thereby avoiding water flowing into the lap joint gap between the second drainage plate 2 and the first drainage plate 1 for erosion, and further ensuring the sealing connection quality between the first drainage plate 1 and the second drainage plate 2.
[0043] The specific sealing connection method includes welding and bonding, and is preferably welding, i.e. after the L-shaped lap joint of the first drainage plate 1 and the second drainage plate 2, the lap joint of the first drainage plate 1 and the second drainage plate 2 is hot melt welded to seal the lap joint gap and make the first drainage plate 1 and the second drainage plate 2 form an integral, thereby strengthening the sealing of the high-low span drainage structure.
[0044] Meanwhile, after welding, sealing material can be applied at the welding seam position to further improve the sealing connection quality between the first drainage plate 1 and the second drainage plate 2, thereby ensuring the closure of the drainage path.
[0045] It should be noted that the specific steps of welding are known to those skilled in the art and do not belong to the core of the present disclosure, and are not described here.
[0046] As shown in FIGS. Figure 2 and Figure 4 In some embodiments, the second drainage plate 2 has a drainage end extending into the drainage channel, and the drainage end of the second drainage plate 2 serves as the outlet of the drainage path formed by the first drainage plate 1 and the second drainage plate 2, in other words, by extending the drainage end of the second drainage plate 2 into the drainage channel, water can be effectively drained.
[0047] Specifically, the closed drainage path formed by the first drainage plate 1 and the second drainage plate 2 means that water in the high-span part 3 will not directly penetrate onto the vertical surface of the structural layer of the high-span part 3, but in order to avoid water accumulation at the high-low span junction 9, the water guided by the drainage path needs to be drained to the drainage well. The drainage channel is used to connect the drainage path and the drainage well, and by extending the drainage end of the second drainage plate 2 into the drainage channel, a closed loop of high-low span drainage is achieved to improve the overall waterproofing effect.
[0048] The specific form of the drainage channel includes a reserved groove 5, a reserved pipeline, etc., and is preferably a reserved groove 5, i.e. a reserved groove 5 is provided on the low-span part 4, and the drainage end of the second drainage plate 2 extends into the reserved groove 5.
[0049] The reason why the drainage end of the second drainage plate 2 extends into the reserved groove 5 instead of being arranged above the reserved groove 5 is to avoid water splashing onto the structural layer facade of the high-span part 3 or the top surface of the low-span part 4, thereby causing water stains.
[0050] As shown in Figure 2 and Figure 4 , in some embodiments, the structural layer facade of the high-span part 3 serves as the groove side wall of the reserved groove 5, and the drainage end of the second drainage plate 2 is inserted into the reserved groove 5 to close the drainage end of the second drainage plate 2, so that water completely flows into the reserved groove 5.
[0051] Specifically, the groove bottom wall of the reserved groove 5 is attached to the bottom surface of the drainage end of the second drainage plate 2, and the insertion of the reserved groove 5 and the second drainage plate 2 also facilitates the installation positioning and fixing of the second drainage plate 2, thereby improving the construction convenience of the high-low span drainage structure.
[0052] Further, the groove depth of the reserved groove 5 is 25mm-35mm, and the groove width of the reserved groove 5 is 15mm-25mm, wherein the groove depth and the groove width of the reserved groove 5 are determined according to the size and drainage capacity of the second drainage plate 2, and those skilled in the art can adaptively adjust the size of the reserved groove 5.
[0053] As shown in Figure 2 , in some embodiments, the side of the second drainage plate 2 away from the structural layer facade of the high-span part 3 is provided with a covering layer 6, which covers the periphery of the second drainage plate 2 and the connection between the second drainage plate 2 and the first drainage plate 1. The covering layer 6 includes flexible waterproof paint and waterproof mortar from inside to outside, and the waterproof mortar is provided with a mesh cloth. The top surface of the covering layer 6 is flush with the top surface of the protective layer of the high-span part 3. By setting the covering layer 6, the second drainage plate 2 and the connection between the second drainage plate 2 and the first drainage plate 1 are waterproofed and protected, thereby improving the waterproof performance of the high-low span drainage structure and prolonging the service life.
[0054] As shown in Figure 2 and Figure 4 , in some embodiments, the high-low span drainage structure further comprises a reserved rebate 7 formed on the low-span part 4, the reserved rebate 7 is formed on the side of the reserved groove 5 away from the high-span part 3 and communicates with the reserved groove 5, the bottom surface of the reserved rebate 7 is higher than the bottom surface of the reserved groove 5, the covering layer 6 extends into the reserved rebate 7, and the thickness of the covering layer 6 is consistent with the thickness of the reserved rebate 7.
[0055] Specifically, the reserved notches 7 and the reserved grooves 5 are in communication with each other to form a concave part with a stepped bottom surface, and the bottom surfaces of the reserved notches 7 and the reserved grooves 5 are coated with waterproof paint, which not only plays a waterproof sealing role, but also makes the bottom surfaces of the reserved notches 7 and the reserved grooves 5 flat, so as to avoid the formation of gaps between the bottom surface of the covering layer 6 and the bottom surface of the reserved notches 7, and the formation of gaps between the drainage end of the second drainage plate 2 and the bottom surface of the reserved grooves 5, thereby improving the waterproof performance of the high-low span drainage structure.
[0056] As shown in Figure 2 In some embodiments, the second drainage plate 2 is connected to the high-span part 3 by a fastener, and the fastener penetrates the drainage protrusion of the second drainage plate 2 and extends into the high-span part 3.
[0057] Specifically, the fastener includes an expansion bolt, a screw 8, etc., and is preferably the screw 8. The screw 8 is inserted into the drainage protrusion from the concave surface of the second drainage plate 2, and the tip of the screw 8 penetrates out of the convex surface of the second drainage plate 2 to the structural layer of the high-span part 3. The head of the screw 8 is in clamping engagement with the drainage protrusion, and the position of the second drainage plate 2 is fixed by fixing the structural layer of the second drainage plate 2 and the high-span part 3 by the fastener, thereby improving the reliability of the high-low span drainage structure.
[0058] Further, a flexible gasket is arranged between the head of the screw 8 and the drainage protrusion, and waterproof paint is applied at the hole of the drainage protrusion through which the screw 8 penetrates.
[0059] The high-low span drainage structure provided by the present disclosure can be applied to the condition that the top surface of the high-span part 3 and the top surface of the low-span part 4 are both horizontal, or the condition that the top surface of the high-span part 3 and the top surface of the low-span part 4 are both inclined, or the condition that the vertical surface of the high-span part 3 is inclined, i.e. the condition that the two adjacent structure parts with height difference have leakage water at the joint due to the non-closed drainage path, and the high-low span drainage structure can be used to repair the leakage water to realize the closed drainage path and ensure the overall waterproof effect.
[0060] In addition, for the condition that there are leakage points on the vertical surface of the structure layer of the height part, the high-low span drainage structure provided by the present disclosure can be used to repair only the leakage points, i.e. only the second drainage plate 2 and the first drainage plate 1 are arranged at the leakage points and welded, thereby saving the repair cost.
[0061] The specific embodiments of the present disclosure further provide the basic steps of repairing the leakage water at the high-low span joint 9 by using the high-low span drainage structure provided by the present disclosure:
[0062] First, the reserved grooves 5 are opened, and sealing material is applied in the reserved grooves 5;
[0063] Second, lay the second drainage plate 2 (the convex surface of the second drainage plate 2 faces the structural layer facade of the high span part 3), insert the drainage end of the second drainage plate 2 into the reserved groove 5, and weld the connecting end of the second drainage plate 2 with the first drainage plate 1;
[0064] Third, screw in the screw 8, set the flexible gasket, and brush the sealing material;
[0065] Fourth, cover the concave surface of the second drainage plate 2 with waterproof paint;
[0066] Fifth, brush waterproof paint at the preset groove and the reserved groove 5;
[0067] Sixth, cover the concave surface of the second drainage plate 2 with waterproof mortar (with built-in mesh cloth).
[0068] In fact, the high-low span drainage structure provided by the present disclosure can be directly applied in the construction stage, and is not only used for waterproof repair of leakage water.
[0069] So far, the embodiments of the present disclosure have been described in detail.
