Description

Technical Field

[0001] This utility model relates to the field of parking roof technology, specifically to a waterproof structure for the expansion joint of a parking roof. Background Technology

[0002] A parking roof is a rooftop structure built on the roof of a building for parking standard micro and small cars. Parking roofs are an effective way to utilize vertical space, saving land resources and alleviating the pressure on ground-level parking.

[0003] In large-scale construction projects, in order to prevent damage caused by excessive stress inside the structure due to factors such as temperature changes and uneven foundation settlement, it is usually necessary to reserve expansion joints at appropriate locations. Expansion joints allow for a certain relative displacement between building components, thereby releasing stress and ensuring the overall safety of the building. When expansion joints are set on the roof of a building, they must not only meet the needs of structural deformation, but also have reliable waterproofing functions to prevent rainwater from seeping into the interior of the building through the gaps.

[0004] For parking roofs that need to withstand frequent vehicle traffic and parking, the expansion joint structure of the parking roof faces more severe challenges. The passage of vehicles will bring continuous dynamic loads, static loads and vibrations. These complex mechanical effects are directly applied to the cover structure above the expansion joint.

[0005] Chinese patent CN204826796U discloses a parking roof expansion joint ramp structure, including a parking roof, an expansion joint between adjacent parking roofs, and telescopic retaining walls on both sides of the edges of the parking roofs along the expansion joint. Rock wool fireproof sealant is filled between the telescopic retaining walls and covered with a cover plate. The lower opening of the rock wool fireproof sealant is supported by a stainless steel cover plate and a drainage ditch is provided. Supporting retaining walls are provided on the parking roofs outside the telescopic retaining walls, and support plates are installed between the supporting retaining walls. A laying layer is laid on the parking roofs outside the supporting retaining walls, with the top surface of the laying layer flush with the top surface of the support plate. A slope is provided on the outer side of the laying layer.

[0006] The aforementioned parking roof structure uses a support plate directly covering the joints filled with elastic sealant. This structure allows the vehicle's load and impact force to be transferred to the waterproof layer below with almost no attenuation. While the waterproof sealant has to withstand this repeated compression and shear stress over a long period of time, it also needs to adapt to the building's thermal expansion and contraction and settlement displacement. This can lead to fatigue damage, detachment from the base layer, or puncture of the waterproof material, thus greatly shortening its effective lifespan and ultimately causing leakage problems. Utility Model Content

[0007] The present invention aims to overcome the defects in the prior art and provide a waterproof structure for the expansion joint of parking roof that is structurally stable, safe, reliable, and durable.

[0008] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a waterproof structure for expansion joints on parking roofs, comprising a roof structural layer and several roof surface layers laid on the roof structural layer, with expansion joints formed between adjacent roof surface layers; an opening groove formed on the roof structural layer is provided in the expansion joint, and a protective cover plate flush with the roof surface layer is laid in the expansion joint; a waterproof component is filled in the opening groove, and a buffer component covering the waterproof component is provided in the expansion joint, with an isolation layer on top of the waterproof component for separating the waterproof component from the buffer component; the buffer component includes a base and an arched elastic cover plate connected to the base, the arched elastic cover plate supporting the protective cover plate, and a guide groove formed on the base for satisfying the deformation of the arched elastic cover plate under stress.

[0009] In a preferred embodiment of this utility model, the opening groove is formed in the middle of the expansion joint and the opening groove is set to open upward.

[0010] As a preferred embodiment of the present invention, the waterproof component includes a waterproof pad laid in the opening groove and an isolation layer laid at the opening of the opening groove, with sealant filling the space between the waterproof pad and the isolation layer.

[0011] As a preferred embodiment of the present invention, the waterproof component further includes an elastic foam rod filled between the waterproof pad and the isolation layer, with the side of the elastic foam rod tightly fitted to the waterproof pad and the isolation layer.

[0012] As a preferred embodiment of this utility model, the base is disposed on opposite sides of the waterproof component, and the base abuts against the side of the roof surface layer, and an elastic sealing gasket is embedded at the joint between the base and the roof surface layer.

[0013] As a preferred embodiment of this utility model, the guide groove is provided along the width direction of the base, and a slider that can move along the length direction of the guide groove is provided in the guide groove. Connecting pieces connected to the slider are formed on both sides of the arched elastic cover plate.

[0014] As a preferred embodiment of this utility model, the connecting piece is provided with a bolt for connecting to the slider, and the connecting piece is abuttingly disposed on the surface of the base.

[0015] In a preferred embodiment of this utility model, the guide groove abuts against the slider on both sides in the width direction.

[0016] As a preferred embodiment of this utility model, the arched elastic cover plate has a downward-opening curved structure, and the middle part of the arched elastic cover plate abuts against the protective cover plate.

[0017] As a preferred embodiment of this utility model, the bottom of the protective cover is provided with reinforcing ribs to enhance the structural strength of the protective cover, and the surface of the protective cover is covered with a decorative layer.

[0018] Compared with existing technologies, by setting a buffer component and a waterproof component below the buffer component in the expansion joint and separating the two by an isolation layer, the problem of the waterproof layer being easily torn or fatigued due to the stress generated by vehicle load and structural displacement in existing technologies is solved. At the same time, by combining the elastic deformation capacity of the arched elastic cover plate with the sliding function of the slider in the guide groove, the problem of the single function of the expansion joint cover plate structure in existing technologies, which makes it difficult to adapt to the two composite deformations of horizontal expansion and vertical settlement and misalignment is solved. The isolation layer effectively protects the integrity and sealing performance of the waterproof components, thereby significantly improving the overall waterproof durability of the expansion joint. The slider and guide groove design enable the structure to effectively cope with the complex displacement of the building, prevent the cover plate from jamming or being damaged, and thus continuously ensure the smooth and safe driving effect of the parking roof.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, a waterproof structure for a parking roof expansion joint includes a roof structure layer 1 and several roof surface layers 4 laid on the roof structure layer 1, with expansion joints 8 formed between adjacent roof surface layers 4; the expansion joint 8 has an opening groove 301 formed on the roof structure layer 1, and a protective cover plate 6 flush with the roof surface layer 4 is laid in the expansion joint 8; the opening groove 301 is filled with a waterproof component 3, and a buffer component 2 covering the waterproof component 3 is provided in the expansion joint 8; the top of the waterproof component 3 has an isolation layer 305 for separating the waterproof component 3 from the buffer component 2; the buffer component 2 includes a base 201 and an arched elastic cover plate 204 connected to the base 201, the arched elastic cover plate 204 supporting the protective cover plate 6, and a guide groove 202 is formed on the base 201 to accommodate the deformation of the arched elastic cover plate 204 under stress.

[0022] The waterproof component 3 includes a waterproof pad 302 laid in the opening groove 301 and an isolation layer 305 laid at the opening of the opening groove 301, with sealant 304 filling the space between the waterproof pad 302 and the isolation layer 305.

[0023] The waterproof component 3 also includes an elastic foam rod 303 that is filled between the waterproof pad 302 and the isolation layer 305. The side of the elastic foam rod 303 is in close contact with the waterproof pad 302 and the isolation layer 305, thereby ensuring that the elastic foam rod 303 is fully filled between the waterproof pad 302 and the isolation layer 305.

[0024] The diameter of the elastic foam rod 303 is set to be larger than the actual width of the expansion joint, so that the elastic foam rod 303 can fit tightly against the side wall of the opening groove 301 after installation.

[0025] The waterproof gasket 302 is laid within the opening groove 301, with the opening groove 301 extending from both sides of the waterproof gasket 302. The sealant 304 adheres to the extended portion of the waterproof gasket 302. The isolation layer 305 is made of non-woven fabric, ensuring reliable isolation between the buffer component 2 and the sealant 304, preventing them from directly adhering and compromising the waterproof performance. The waterproof gasket 302 extends upwards on both sides with openings 301 and sufficient width, so that the sealant 304 that is subsequently filled can be tightly bonded to the extended part of the waterproof gasket 302 to form a continuous flexible sealing and waterproof layer.

[0026] The base 201 is located on opposite sides of the waterproof component 3 and abuts against the side of the roof surface layer 4. An elastic sealing gasket 207 is embedded at the joint between the base 201 and the roof surface layer 4. The elastic sealing gasket 207 is configured to block the water seepage path at the edge of the buffer component 2.

[0027] The guide groove 202 is provided along the width direction of the base 201. The guide groove 202 is provided with a slider 203 that can move along the length direction of the guide groove 202. The arched elastic cover plate 204 has connecting pieces 205 on both sides that are connected to the slider 203.

[0028] The connecting piece 205 is provided with bolts 206 that are connected to the slider 203. The connecting piece 205 is abutted on the surface of the base 201, and the guide groove 202 abuts against the slider 203 on both sides in the width direction.

[0029] Bolt 206 passes through connecting piece 205 and is threadedly connected to slider 203. Under the action of the slider 203 side against guide groove 202, the rotation of slider 203 is restricted, thereby achieving locking between connecting piece 205 and slider 203 under the action of thread and helix 206.

[0030] The slider 203 and the guide groove 202 of the base 201 form a sliding fit connection. This track-type sliding fit structure provides free horizontal sliding space for the arched elastic cover plate 204 and the connecting piece 205, ensuring that the entire structure can adapt to the expansion and contraction deformation of the expansion joint caused by temperature changes.

[0031] The arched elastic cover plate 204 has a downward-opening curved structure. The middle part of the arched elastic cover plate 204 abuts against the protective cover plate 6. The arched elastic cover plate 204 disperses the vehicle load stress on the upper part to the base 201 on both sides through its own arched structure, and adapts to the vertical misalignment caused by uneven settlement of the structures on both sides of the expansion joint through its own elastic deformation.

[0032] The bottom of the protective cover plate 6 is provided with reinforcing ribs 7 to enhance the structural strength of the protective cover plate 6. The surface of the protective cover plate 6 is covered with a decorative layer 5. The reinforcing ribs 7 are used to enhance the load-bearing strength of the protective cover plate 6 and avoid local stress concentration.

[0033] In practical use, the expansion joint 8 is used between building components to absorb the relative displacement caused by temperature changes, uneven foundation settlement, and external loads. The roof structure layer 1 serves as the load-bearing foundation. Long-term dynamic and static loads and vibrations from vehicle traffic or parking can cause vertical displacement or horizontal expansion and contraction of the structures on both sides. Since the arched elastic cover plate 204 spans the expansion joint, when under pressure, it disperses the upper load stress to both sides through its arched structure and adapts to the different heights of the structures on both sides through deformation. In the buffer assembly 2, the bolt 206 passes through the connecting piece 205 and is threadedly connected to the slider 203, securing the arched elastic cover plate 204. Fixed to the base 201, the guide groove 202 and the slider 203 provide horizontal sliding space for the arched elastic cover plate 204 and the connecting piece 205, so that the arched elastic cover plate 204 can adapt to horizontal expansion and contraction deformation. The elastic sealing gasket 207 is embedded in the joint between the base 201 and the roof surface layer 4, sealing the water seepage path between the edge of the base 201 and the arched elastic cover plate 204, and playing a certain waterproof role. The protective cover plate 6 is used to protect the components below, preventing vehicles from directly running over them. The evenly laid reinforcing ribs 7 enhance the bearing strength of the protective cover plate 6 and prevent local stress concentration. At the same time, the protective cover plate 6 is flush with the surface layer 5 to ensure smooth vehicle passage.

[0034] Furthermore, the waterproof pad 302 in the waterproof component 3 is laid in the opening groove 301 as the bottom waterproof layer. At the same time, the waterproof pad 302 extends out of the opening groove 301 on both sides with sufficient width. Then, the elastic foam rod 303 is placed in the opening groove 301 to fill the deformation cavity. It absorbs the expansion or settlement deformation of the structure by its own elasticity. The diameter of the elastic foam rod 303 is larger than the width of the gap, so that the elastic foam rod 303 can fit the gap. Then, the sealant 304 is filled and bonded to the extended part of the waterproof pad 302 to form a flexible sealing waterproof layer. Through the multi-layer waterproof effect, it forms a complementary and effective waterproof layer. Then, the non-woven fabric isolation layer 305 is covered on top of the sealant 304 to isolate the upper components and prevent them from directly adhering to the sealant 304 and damaging the waterproof performance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0036] Although this document frequently uses reference numerals from the figures, such as 1 for roof structure layer, 2 for buffer component, 201 for base, 202 for guide groove, 203 for slider, 204 for arched elastic cover plate, 205 for connecting piece, 206 for bolt, 207 for elastic sealing gasket, 3 for waterproof component, 301 for opening groove, 302 for waterproof pad, 303 for elastic foam rod, 304 for sealant, 305 for isolation layer, 4 for roof surface layer, 5 for finishing layer, 6 for protective cover plate, 7 for reinforcing rib, and 8 for expansion joint, the possibility of using other terms is not excluded.
