Description

Technical Field

[0001] The invention relates to the technical field of building waterproof engineering, and 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 ceiling and the balcony is the focus and difficulty of waterproofing construction. Due to the material and structural differences between the basement ceiling and the balcony, as well as temperature changes, foundation settlement and other factors, cracks are prone to appear at the joint, leading to water seepage and leakage.

[0004] Therefore, we 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 prone to occur at the joints, leading to problems such as 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 soil layer, a retaining wall is fixedly arranged on the upper surface of the top plate, a balcony is fixedly arranged on the upper surface of the retaining wall, a sealing member is fixedly arranged 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, which effectively prevents water from seeping in from the corner between the waterproof layer and the retaining wall. The corner between the top plate and the retaining wall is sealed and waterproofed through 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 and prevents water seepage and leakage.

[0011] As a preferred embodiment of the underground garage roof construction waterproof structure and its 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 of the 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 waterproof structure and its 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 with three slide plates, one side of the outer surfaces of the three slide plates is fixedly connected with a splint, and the inner side surface of the splint is fitted with the anti-penetration layer.

[0013] As a preferred embodiment of the underground garage roof waterproof structure and its construction method provided by the present invention, the outer surface of the turntable is fixedly connected with three mounting blocks 1, the inner sides of the three slides are fixedly connected with 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.

[0014] As a preferred embodiment of the underground garage roof waterproofing structure and its construction method provided by the present invention, a cavity is opened inside the balcony above the slide slot, a rotating shaft is fixedly connected to the center position of the upper surface of the slide plate, the upper end of the rotating shaft is rotatably connected to the cavity, a worm gear is fixedly connected to the outer surface of the rotating shaft, and a worm is meshingly connected to the outer surface of the worm gear.

[0015] As a preferred embodiment of the underground garage roof construction waterproof structure and its 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 for rotation.

[0016] As a preferred embodiment of the underground garage roof construction waterproof structure and its 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 its construction method provided by the present invention, the anti-penetration layer is an SBS modified asphalt root-penetration-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 closely attached to the outer wall of the retaining wall through the fixing parts, effectively preventing water from penetrating 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 through 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 sliding plates slide synchronously inside the sliding groove, thereby driving the three clamping plates to move toward the anti-penetration layer, so that the waterproof layer and the anti-penetration layer are closely attached 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 positions of the sliding 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, the retaining wall and the 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 in from the angle between the waterproof layer and the retaining wall. Both waterproof layers are PCM self-adhesive modified asphalt waterproof membranes, which are simple to construct and have excellent waterproof performance. At the same time, the anti-penetration layer is SBS modified asphalt root-piercing waterproof membrane, which can improve the waterproof effect and prevent plant roots from penetrating the anti-penetration layer to damage the waterproof layer and the top plate, resulting in 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, which effectively prevents water from seeping in from the corner between the waterproof layer and the retaining wall. The corner between the top plate and the retaining wall is sealed and waterproofed through 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 and prevents water seepage and leakage.
