Description

Technical Field

[0001] The present invention relates to the technical field of building waterproof engineering, in particular to a waterproof structure for underground garage roof construction and a construction method thereof. Background Art

[0002] An underground garage refers to a parking space designed and built in the underground or semi-underground space of a building. As an important part of modern urban planning and architectural design, it has multiple characteristics and functions. In the construction of underground garages, pipes (such as water supply and drainage pipes, HVAC pipes, etc.) often need to pass through the roof for connection.

[0003] In modern buildings, the joint between the basement roof and the balcony is the focus and difficulty of waterproofing construction. Due to the differences in material and structure between the basement roof and the balcony, as well as factors such as temperature changes and foundation settlement, cracks are prone to appear at the joint, leading to water seepage and leakage.

[0004] Therefore, we have made improvements to this and proposed a waterproof structure and construction method for the underground garage roof. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that due to the differences in materials and structures between the basement roof and the balcony, as well as factors such as temperature changes and foundation settlement, cracks are easily formed at the joints, leading to problems of water seepage and leakage.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0007] The waterproof structure and construction method of the underground garage roof are constructed to improve the above problems.

[0008] The specific application is as follows:

[0009] It includes a top plate and a backfill layer, a retaining wall is fixedly provided on the upper surface of the top plate, a balcony is fixedly provided on the upper surface of the retaining wall, a sealing member is fixedly provided on the upper surface of the top plate, a slide groove is provided inside the balcony, and a fixing member for auxiliary fixing of the sealing member is slidably connected to the inner surface of the slide groove.

[0010] The waterproof layer and the anti-penetration layer are tightly fitted to the outer wall of the retaining wall through fixings, effectively preventing water from seeping in from the angle between the waterproof layer and the retaining wall. The angle between the top plate and the retaining wall is sealed and waterproofed by the chamfer in the sealing component. The three-layer waterproofing of two waterproof layers and one anti-penetration layer greatly improves the waterproof effect between the top plate and the balcony, preventing water seepage and leakage.

[0011] As a preferred embodiment of the underground garage roof construction waterproof structure and construction method provided by the present invention, the sealing member includes a waterproof layer, three chamfers are fixedly arranged between the upper surface of the roof and the outer surface of the retaining wall, two waterproof layers are fixedly arranged between the roof and the retaining wall, an anti-penetration layer is fixedly arranged on the upper surface of the waterproof layer, and the backfill soil layer is arranged above the anti-penetration layer.

[0012] As a preferred embodiment of the underground garage roof waterproofing structure and construction method provided by the present invention, the fixing part includes a turntable and a rotating plate. The turntable is rotatably arranged inside the slide groove. The inner surface of the slide groove is slidably connected to three slide plates. One side of the outer surface of the three slide plates is fixedly connected to a plywood, and the inner side surface of the plywood is fitted with the anti-penetration layer.

[0013] As a preferred embodiment of the underground garage roof waterproofing structure and construction method provided by the present invention, the outer surface of the turntable is fixedly connected to three mounting blocks 1, the inner sides of the three slides are fixedly connected to mounting blocks 2, and three rotating plates are provided. One end of the rotating plate is rotatably connected to mounting block 1 through a rotating shaft, and the other end of the rotating plate is rotatably connected to mounting block 2 through a rotating shaft.

[0015] As a preferred embodiment of the underground garage roof construction waterproof structure and construction method provided by the present invention, one end of the worm is rotatably connected to the cavity, and the other end of the worm extends to the outside of the balcony and is rotatably arranged.

[0016] As a preferred embodiment of the underground garage roof construction waterproof structure and construction method provided by the present invention, the waterproof layer is a PCM self-adhesive modified asphalt waterproof membrane.

[0017] As a preferred embodiment of the underground garage roof construction waterproof structure and construction method provided by the present invention, the anti-penetration layer is an SBS modified asphalt root-puncture-resistant waterproof membrane.

[0018] The construction method of the underground garage roof waterproof structure includes the above-mentioned underground garage roof waterproof structure, and the specific operations are as follows:

[0019] When in use, the waterproof layer and the anti-penetration layer are tightly fitted to the outer wall of the retaining wall through the fixing parts, effectively preventing water from seeping in from the angle between the waterproof layer and the retaining wall. The angle between the top plate and the retaining wall is sealed and waterproofed by the chamfer in the sealing part. The three-layer waterproofing of two waterproof layers and one anti-penetration layer greatly improves the waterproof effect between the top plate and the balcony, preventing water seepage and leakage.

[0020] The rotating worm drives the worm wheel to rotate, thereby driving the rotating shaft and the turntable to rotate counterclockwise. The rotation of the rotating shaft drives the three rotating plates to rotate around the mounting block 1 and the mounting block 2. At the same time, the three slide plates slide synchronously inside the slide groove, thereby driving the three clamping plates to move toward the anti-penetration layer. The waterproof layer and the anti-penetration layer are tightly fitted to the outer wall of the retaining wall under the clamping action of the clamping plates. At the same time, the self-locking action of the worm wheel and the worm fixes the position of the slide plates and the clamping plates.

[0021] The angle between the top plate and the retaining wall is sealed by setting the chamfer, and the backfill soil layer is isolated from the top plate, retaining wall and chamfer by setting the waterproof layer and the anti-penetration layer. At the same time, the top of the waterproof layer and the anti-penetration layer are tightly fitted with the outer wall of the retaining wall through the clamping effect of the plywood, which can effectively prevent water from seeping into the angle between the waterproof layer and the retaining wall. Both waterproof layers are PCM self-adhesive modified asphalt waterproof membrane, which is simple to construct and has excellent waterproof performance. At the same time, the anti-penetration layer is SBS modified asphalt root-resistant puncture waterproof membrane, which not only improves the waterproof effect, but also prevents plant roots from penetrating the anti-penetration layer to damage the waterproof layer and the top plate, causing penetration of the top plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The waterproof layer and the anti-penetration layer are tightly fitted to the outer wall of the retaining wall through fixings, effectively preventing water from seeping in from the angle between the waterproof layer and the retaining wall. The angle between the top plate and the retaining wall is sealed and waterproofed by the chamfer in the sealing component. The three-layer waterproofing of two waterproof layers and one anti-penetration layer greatly improves the waterproof effect between the top plate and the balcony, preventing water seepage and leakage.

[0041] Example 1

[0042] Please refer to Figure 1-3The invention relates to a waterproof structure for the roof of an underground garage and a construction method thereof, comprising a roof 1 and a backfill soil layer 13. A retaining wall 11 is fixedly provided on the upper surface of the roof 1. A balcony 12 is fixedly provided on the upper surface of the retaining wall 11. A sealing member is fixedly provided on the upper surface of the roof 1. A chute 3 is provided inside the balcony 12. A fixing member for auxiliary fixing of the sealing member is slidably connected to the inner surface of the chute 3. The fixing member comprises a turntable 33 and a rotating plate 36. The turntable 33 is rotatably arranged inside the chute 3. Three slide plates 31 are slidably connected to the inner surface of the chute 3. A clamping plate 32 is fixedly connected to one side of the outer surface of each of the three slide plates 31. The inner side surface of the clamping plate 32 is arranged to be in contact with the anti-penetration layer 22. Three mounting blocks 34 are fixedly connected to the outer surface of the turntable 33. Mounting blocks 35 are fixedly connected to the inner surfaces of the three slides 31. Three rotating plates 36 are provided. One end of each rotating plate 36 is rotatably connected to the mounting block 34 via a rotating shaft, and the other end of each rotating plate 36 is rotatably connected to the mounting block 35 via a rotating shaft. A cavity 4 is defined within the balcony 12, above the chute 3. A rotating shaft 43 is fixedly connected to the center of the upper surface of the slide 31. The upper end of the rotating shaft 43 is rotatably connected to the cavity 4. A worm gear 41 is fixedly connected to the outer surface of the rotating shaft 43. A worm 42 is meshedly connected to the outer surface of the worm gear 41. One end of the worm 42 is rotatably connected to the cavity 4, and the other end of the worm 42 extends to the outside of the balcony 12 for rotation.

[0043] Implementation process: Rotating the worm 42 drives the worm wheel 41 to rotate, thereby driving the rotating shaft 43 and the turntable 33 to rotate counterclockwise. The rotation of the rotating shaft 43 drives the three rotating plates 36 to rotate around the mounting block 1 34 and the mounting block 2 35. At the same time, the three slides 31 slide synchronously inside the slide groove 3, thereby driving the three clamping plates 32 to move toward the anti-penetration layer 22, so that the waterproof layer 21 and the anti-penetration layer 22 are tightly fitted with the outer wall of the retaining wall 11 under the clamping action of the clamping plates 32. At the same time, the self-locking action of the worm wheel 41 and the worm 42 fixes the positions of the slides 31 and the clamping plates 32.

[0044] Implementation benefits: The anti-penetration layer 22 and the waterproof layer 21 are tightly fitted to the outer wall of the retaining wall 11 .

[0045] Example 2

[0046] The seal includes a waterproof layer 21. Three chamfers 2 are fixedly positioned between the upper surface of the top plate 1 and the outer surface of the retaining wall 11. Two waterproof layers 21 are fixedly positioned between the top plate 1 and the retaining wall 11. An anti-penetration layer 22 is fixedly positioned on the upper surface of the waterproof layer 21. The backfill layer 13 is positioned above the anti-penetration layer 22. The waterproof layer 21 is a PCM self-adhesive modified asphalt waterproof membrane. The anti-penetration layer 22 is an SBS modified asphalt root-penetration-resistant waterproof membrane.

[0047] Implementation process: The angle between the top plate 1 and the retaining wall 11 is sealed by setting the chamfer 2, and the backfill soil layer 13 is isolated from the top plate 1, the retaining wall 11 and the chamfer 2 by setting the waterproof layer 21 and the anti-penetration layer 22. At the same time, the top of the waterproof layer 21 and the anti-penetration layer 22 are tightly fitted with the outer wall of the retaining wall 11 through the clamping effect of the plywood 32, which can effectively prevent water from seeping into the angle between the waterproof layer 21 and the retaining wall 11. The two waterproof layers 21 are both PCM self-adhesive modified asphalt waterproof membranes with simple construction and excellent waterproof performance. At the same time, the anti-penetration layer 22 is SBS modified asphalt root-resistant puncture waterproof membrane, which can improve the waterproof effect while preventing plant roots from penetrating the anti-penetration layer 22 to damage the waterproof layer 21 and the top plate 1, causing penetration of the top plate 1.

[0048] Implementation benefits: The three-layer waterproofing of the two waterproof layers 21 and the one anti-penetration layer 22 greatly improves the waterproofness of the top plate 1 and prevents water seepage and leakage.

[0049] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
