Description

Technical Field

[0001] The invention belongs to the technical field of basement waterproofing, and specifically relates to a basement floor waterproof structure and a waterproof method. Background Art

[0002] A basement floor waterproof structure is a composite system that combines structural self - waterproofing and a flexible waterproof layer. The structural self - waterproofing is achieved by using waterproof concrete with impermeability performance (such as adjusting the aggregate gradation, adding admixtures, or optimizing the vibration process), while the flexible waterproof layer forms a continuous and airtight waterproof barrier by laying polymer - modified asphalt membranes, polymer waterproof membranes, or applying waterproof coatings such as polyurethane and JS on the surface of the concrete floor.

[0003] In the prior art, splicing plates form a physical barrier through specific structures (such as tongue - and - groove joints, card slots, or mechanical fixation). The gaps between the plates are filled with elastic sealant or water - swelling waterstops to adapt to deformation and seal the water seepage channels. At the same time, a waterproof coating with high elongation and bonding strength (such as polyurethane or non - curing rubber asphalt coating) is applied on its surface. This coating not only covers the splicing plates and the gaps to form a continuous waterproof film but also penetrates into the micropores of the gaps to enhance the sealing performance.

[0004] The above - mentioned solutions still have some problems in actual application. Although the existing devices can complete the waterproof work of underground facilities, for temporary and emergency projects, in order to facilitate rapid erection and demolition, splicing plates are used to install the top of the basement. However, due to the volume change of the splicing plate material caused by humidity or temperature changes, for example, concrete may shrink due to water loss during the hardening process, resulting in cracks at the edges of the splicing plates. These cracks will provide potential seepage channels for rainwater. At this time, liquids such as rainwater can penetrate through the cracks to the lower part of the splicing plates, causing the waterproof layer to lose its due waterproof effect. Even if the waterproof layer itself has good quality, micro - cracks will become the starting point of leakage, seriously affecting the waterproof performance.

[0005] Therefore, the present invention provides a basement floor waterproof structure and a waterproof method. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A basement floor waterproof structure of the present invention includes splicing plates. A cavity is provided inside the splicing plates, an inclined drainage assembly is provided inside the splicing plates, and a downward - pressing buckle mechanism is provided inside the splicing plates. The downward pressing and buckling mechanism includes an annular fixing plate. A groove is provided in the middle of the annular fixing plate. Through the setting of the groove in the annular fixing plate, the rainwater leaking at the joint of the splicing plates can be collected. A first downward pressing plate is slidably arranged at the bottom of the annular fixing plate. Through the blocking of the annular fixing plate, the installation and disassembly of the splicing plates are facilitated.

[0008] Preferably, the inclined drainage assembly includes a first inclined plate. The first inclined plate is fixedly connected to the side wall of the splicing plate. A second inclined plate is clamped inside the first inclined plate. A first drainage pipe is fixedly connected through the inside of the first inclined plate. The first drainage pipe is fixedly connected through the inside of the second inclined plate. A drain pipe is penetrated and opened on the side of the inclined part of the splicing plate.

[0009] Preferably, multiple groups of splicing plates are arranged during installation. The first inclined plates or the second inclined plates provided on the opposite sides of the splicing plates are the same. The top of the first inclined plate is of an arc-shaped structure and wraps the top of the second inclined plate inside. The sides of the second inclined plate and the first inclined plate close to the inner cavity of the splicing plate are both of an inclined structure. The drain pipe is located at the lowest end of the inclined side of the splicing plate. The first inclined plate is made of an elastic material.

[0010] Preferably, the downward pressing and buckling mechanism includes a first displacement column. A suction cup is fixedly connected to the top of the first displacement column. The suction cup at the top of the first displacement column can adsorb at the joint of multiple groups of splicing plates after installation, so as to guide the water flow flowing through the joint; The middle of the first displacement column is fixedly connected with an annular fixing plate.

[0011] Preferably, a cone is arranged in the groove in the middle of the annular fixing plate. The cone arranged in the middle of the annular fixing plate facilitates the diversion of the collected rainwater and makes it flow towards the edge of the annular fixing plate; A drainage pipe is fixedly connected through the outer ring surface of the annular fixing plate. Multiple groups of drainage pipes are provided and correspond to the inner cavities of one splicing plate respectively. The drainage pipes on the outer ring surface of the annular fixing plate are in an inclined state.

[0012] Preferably, a first spring is fixedly connected to the bottom of the annular fixing plate. The other end of the first spring is fixedly connected with a first downward pressing plate. The first downward pressing plate is slidably connected to the outer ring surface of the first displacement column. The bottom of the first displacement column is fixedly connected with a second downward pressing plate.

[0013] Preferably, the setting of the first spring facilitates the timely reset of the first downward pressing plate. The second downward pressing plate is of a frustum structure. When the opposite sides of the first downward pressing plate and the second downward pressing plate are abutted, a structure similar to a "dish" will be formed.

[0014] Preferably, a cavity is formed inside the second inclined plate. A limiting plate is fixedly connected to the side wall of the cavity of the second inclined plate. A second spring is fixedly connected to the side wall of the limiting plate. The other end of the second spring is fixedly connected to a trapezoidal block. The trapezoidal block has a trapezoidal structure. A second displacement column is fixedly connected to the side surface of the trapezoidal block. The end of the second displacement column away from the trapezoidal block is fixedly connected to a blocking plate.

[0015] Preferably, the second spring is sleeved on the outer ring surface of the second displacement column and is located on the side opposite to the limiting plate and the trapezoidal block. The setting of the second spring facilitates the reset of the trapezoidal block. When the trapezoidal block abuts against the top of the second lower pressing plate, the buckling mechanism will be fixed. The size of the blocking plate is larger than that of the limiting plate. The setting of the blocking plate can limit the second displacement column and prevent the second displacement column from detaching from the limiting plate due to excessive force during the reset of the second spring.

[0016] A waterproof method for the basement floor slab is as follows: Base treatment: Clean the upper and lower sides of the splicing plate to ensure the flatness and smoothness of the base layers on the upper and lower sides of the splicing plate, and add a waterproof additional layer at the splicing plate. Waterproof layer laying: Lay the waterproof layer on the upper and lower sides of the splicing plate to ensure the reliable connection between the waterproof material and the additional layer. Laying: Align the first inclined plate and the second inclined plate between the two splicing plates, and snap the second inclined plate into the first inclined plate. Since the top of the first inclined plate has an arc structure and wraps the top of the second inclined plate, there is no gap at the top of the assembly composed of the first inclined plate and the second inclined plate at this time. At the same time, because the arc structure at the top of the first inclined plate is at the joint of the two splicing plates, when the waterproof layer on the splicing plate leaks, it can divert the leaked water.

[0017] The beneficial effects of the present invention are as follows: 1. In a waterproof structure for the basement floor slab of the present invention, when the inclined surface of the second lower pressing plate moves to the bottom of the trapezoidal block, the second spring will reset because it is not blocked by an external force. While resetting, it will drive the trapezoidal block and the second displacement column to move linearly along the guidance of the limiting plate. When the bottom of the trapezoidal block contacts the top of the second lower pressing plate, the pressing buckle mechanism will be fixed. Since the limiting plate is fixed inside the second inclined plate, and the second inclined plate is stuck inside the first inclined plate, when the first displacement column presses down, the splicing plate can be quickly installed, which can reduce the time for manual adjustment and positioning, and thus improve the installation efficiency. At the same time, when the first displacement column is not pressed, the bottom of the suction cup on the top of the first displacement column contacts the tops of the four splicing plates. After the first displacement column performs the pressing operation, the first displacement column will adsorb on the top where the four splicing plates meet. Therefore, when rainwater appears on the top of the splicing plates, the rainwater will flow out of the junction area along the edge of the suction cup, thereby improving the waterproof performance of the splicing plates.

[0018] 2. In a waterproof structure for the basement floor slab of the present invention, when the second inclined plate enters the arc-shaped structure of the first inclined plate, the squeezed part will reset and wrap the top of the second inclined plate. Since the top of the first inclined plate is directly below the gap between the two splicing plates, when rainwater leaks into the splicing plates through the gap, it will be respectively diverted to the cavities of the adjacent splicing plates through the first inclined plate, preventing water from accumulating at the gap or further penetrating to the base layer, thereby significantly reducing the leakage risk. Since the waterproof layer composed of multiple splicing plates is in an inclined state, the water in the cavities of the splicing plates will flow into the inner cavity of the last splicing plate through the first drainage pipe and be discharged through the drainage pipe, reducing the residence time of the infiltrated water in the cavities of the splicing plates, and thus enhancing the waterproof effect.

[0019] 3. In a waterproof structure for the basement floor slab of the present invention, due to the damage of the waterproof layer at the top, the suction cup on the top of the first displacement column will fail. At this time, the rainwater will penetrate downward along the junction of the splicing plates. Since the splicing plates are in contact with the first displacement column, when leakage occurs, the rainwater will flow downward along the outer ring surface of the first displacement column. When the rainwater flows to the annular fixing plate, since the annular fixing plate has a groove structure, the rainwater will be temporarily stored inside the annular fixing plate. However, since a conical structure is provided in the middle of the annular fixing plate and a drainage pipe is provided through the outer ring surface of the annular fixing plate, when the rainwater flows into the annular fixing plate, it will gather around the annular fixing plate through the conical structure and flow into the cavity of the splicing plate through the drainage pipe, and be discharged outside the device through the first drainage pipe, thereby preventing rainwater from remaining at the junctions of multiple groups of splicing plates and further improving the overall waterproof performance of the device.

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners. Embodiment 1

[0024] As Figures 1 to 7 shown, one implementation manner of the present invention is as follows: It includes a splicing plate 1, a cavity is arranged inside the splicing plate 1, an inclined drainage component 2 is arranged inside the splicing plate 1, and a press-down buckle mechanism 3 is arranged inside the splicing plate 1; The press-down buckle mechanism 3 includes a ring-shaped fixing plate 302, a groove is arranged in the middle of the ring-shaped fixing plate 302, and the rainwater leaking at the joint of the splicing plate 1 can be collected through the groove of the ring-shaped fixing plate 302. The first lower pressing plate 304 is slidably arranged at the bottom of the ring-shaped fixing plate 302, and the installation and disassembly of the splicing plate 1 are facilitated by the blockage of the ring-shaped fixing plate 302.

[0025] Specifically, although existing devices can complete the waterproofing work of underground facilities, for temporary and emergency projects, in order to facilitate rapid construction and demolition, splicing plates 1 are used to install the top of the basement. However, due to the fact that the materials of the splicing plates 1 may change in volume due to humidity or temperature changes. For example, concrete may shrink due to water loss during the hardening process, resulting in cracks at the edges of the splicing plates 1. These cracks can provide potential infiltration channels for rainwater. At this time, liquids such as rainwater can penetrate through the cracks to the lower part of the splicing plates 1, causing the waterproof layer to lose its due waterproof effect. Even if the waterproof layer itself has good quality, micro-cracks can also become the starting point of leakage, seriously affecting the waterproof performance. Therefore, the present invention solves this problem by setting a certain structure. Since waterproof layers are provided on both the top and bottom of the splicing plates 1 during production, when installation is required, only splicing is needed to complete the splicing work on the top of the basement. However, for temporary and emergency projects, in order to facilitate rapid construction and demolition, splicing plates 1 are used to install the top of the basement. However, due to the fact that the materials of the splicing plates 1 may change in volume due to humidity or temperature changes. For example, concrete may shrink due to water loss during the hardening process, resulting in cracks at the edges of the splicing plates 1. These cracks can provide potential infiltration channels for rainwater. At this time, liquids such as rainwater can penetrate through the cracks to the lower part of the splicing plates 1, causing the waterproof layer to lose its due waterproof effect. Even if the waterproof layer itself has good quality, micro-cracks can also become the starting point of leakage, seriously affecting the waterproof performance. At this time, the inclined drainage assembly 2 can divert the water leaking from the top of the splicing plates 1, thereby protecting the waterproof layer at the bottom, and thus improving the waterproof effect of the splicing plates 1. At the same time, since the gaps at the joints of multiple splicing plates 1 are relatively complex, the rainwater leaking through the joints will be temporarily stored by the annular fixing plate 302 at this time, and at the same time, it will be diverted through the diversion pipes on its outer ring surface, thereby further improving the waterproof performance of the splicing plates 1.

[0026] As Figure 4 shown, the pressing and buckling mechanism 3 in this embodiment includes a first displacement column 301. A suction cup is fixedly connected to the top of the first displacement column 301. The suction cup at the top of the first displacement column 301 can adsorb at the joints of multiple splicing plates 1 after installation, so as to divert the water flowing through the joints. A ring-shaped fixing plate 302 is fixedly connected to the middle of the first displacement column 301.

[0027] As Figure 4 shown, a first spring 303 is fixedly connected to the bottom of the ring-shaped fixing plate 302 in this embodiment. The other end of the first spring 303 is fixedly connected to a first lower pressing plate 304. The first lower pressing plate 304 is slidably connected to the outer ring surface of the first displacement column 301. A second lower pressing plate 305 is fixedly connected to the bottom of the first displacement column 301.

[0028] As shown Figure 5 In the second inclined plate 202 of this embodiment, a cavity is provided inside. A limiting plate 306 is fixedly connected to the side wall of the cavity of the second inclined plate 202. A second spring 307 is fixedly connected to the side wall of the limiting plate 306. The other end of the second spring 307 is fixedly connected to a trapezoidal block 308. The trapezoidal block 308 has a trapezoidal structure. A second displacement column 309 is fixedly connected to the side surface of the trapezoidal block 308. One end of the second displacement column 309 away from the trapezoidal block 308 is fixedly connected to a partition plate 310.

[0029] Specifically, when the splicing plate 1 needs to be installed, since the pressing buckle mechanism 3 slides on the upper part of any splicing plate 1, when four splicing plates 1 need to be installed, first install the splicing plate 1 with the pressing buckle mechanism 3 to the top of the basement. At this time, manually move the part with the arc-shaped opening at the top of the other three splicing plates 1 to fit the outer ring surface of the first displacement column 301. At the same time, it is necessary to ensure that the four splicing plates 1 are all on the same horizontal plane; At this time, manually press the first displacement column 301. Since the second lower pressing plate 305 is fixed to the bottom of the first displacement column 301, when the first displacement column 301 moves downward, the second lower pressing plate 305 will also move synchronously. At the same time, since the outer ring surface of the second lower pressing plate 305 is arc-shaped and inclined, when the outer ring surface of the second lower pressing plate 305 abuts against the inclined surface of the trapezoidal block 308, the trapezoidal block 308 will move along the guide of the limiting plate 306 to the side away from the first displacement column 301, and will synchronously drive the second displacement column 309 and the partition plate 310 to move synchronously during the movement. At this time, the second spring 307 is in a compressed state; When the inclined surface of the second lower pressing plate 305 moves to the bottom of the trapezoidal block 308, the second spring 307 will reset due to not being blocked by an external force, and will drive the trapezoidal block 308 and the second displacement column 309 to move linearly along the guide of the limiting plate 306 during the reset. When the bottom of the trapezoidal block 308 contacts the top of the second lower pressing plate 305, the pressing buckle mechanism 3 will be fixed. Since the limiting plate 306 is fixed inside the second inclined plate 202, and the second inclined plate 202 is stuck inside the first inclined plate 201, when the first displacement column 301 is pressed down, the splicing plate 1 can be quickly installed, so that the time for manual adjustment and positioning can be reduced, and the installation efficiency can be improved. At the same time, since the bottom of the suction cup at the top of the first displacement column 301 contacts the top of the four splicing plates 1 when the first displacement column 301 is not pressed, and the first displacement column 301 will adsorb on the top where the four splicing plates 1 meet after the first displacement column 301 performs the pressing work, when rainwater appears on the top of the splicing plate 1, the rainwater will flow out of the joint area along the edge of the suction cup, so that the waterproof performance of the splicing plate 1 can be improved.

[0030] As Figure 7 shown, the inclined drainage component 2 in this embodiment includes a first inclined plate 201, the first inclined plate 201 is fixedly connected to the side wall of the splicing plate 1, a second inclined plate 202 is clamped inside the first inclined plate 201, a first drainage pipe 203 is fixedly connected through the inside of the first inclined plate 201, the first drainage pipe 203 is fixedly connected through the inside of the second inclined plate 202, and a drain pipe 204 is penetrated and opened on the side surface of the inclined part of the splicing plate 1.

[0031] As Figure 7 shown, multiple groups of the splicing plates 1 are provided during installation in this embodiment, the first inclined plates 201 or the second inclined plates 202 provided on the opposite sides of the splicing plate 1 are the same, the top of the first inclined plate 201 is of an arc-shaped structure and wraps the top of the second inclined plate 202 inside, both the second inclined plate 202 and the side of the first inclined plate 201 close to the inner cavity of the splicing plate 1 are of an inclined structure, the drain pipe 204 is located at the lowest end of the inclined side of the splicing plate 1, and the first inclined plate 201 is made of an elastic material.

[0032] Specifically, when the splicing plate 1 encounters long-term rainfall, since the material of the splicing plate 1 will change in volume due to humidity or temperature changes, the waterproof layer on the top will be damaged at this time, and rainwater will penetrate into the inside along the joints of the splicing plate 1; Before the splicing plate 1 is installed with the pressing buckle mechanism 3, it will also be pre-fixed by the clamping connection between the first inclined plate 201 and the second inclined plate 202. When the first inclined plate 201 and the second inclined plate 202 are spliced, first insert the first drainage pipe 203 into the circular hole penetrating through the inside of the second inclined plate 202. At this time, the splicing plate 1 with the second inclined plate 202 will move towards the first inclined plate 201, and the first inclined plate 201 will be squeezed during the movement. Since the top of the second inclined plate 202 is lower than the top of the first inclined plate 201, and the first inclined plate 201 is made of flexible material, when the second inclined plate 202 moves towards the first inclined plate 201, it will squeeze the arc-shaped structure at the top of the first inclined plate 201. When the second inclined plate 202 enters the arc-shaped structure of the first inclined plate 201, the squeezed part will reset and wrap the top of the second inclined plate 202. Since the top of the first inclined plate 201 is directly below the gap between the two splicing plates 1, when rainwater leaks into the inside of the splicing plate 1 through the gap, it will be respectively diverted to the cavities of the adjacent splicing plates 1 through the first inclined plate 201, avoiding the accumulation of water at the gap or further penetration to the base layer, thus significantly reducing the leakage risk. Since the waterproof layer composed of multiple splicing plates 1 is in an inclined state, the water in the cavity of the splicing plate 1 will flow through the first drainage pipe 203 into the inner cavity of the last splicing plate 1 and be discharged through the drain pipe 204, thereby reducing the residence time of the infiltrated water in the cavity of the splicing plate 1, and thus enhancing the waterproof effect.

[0033] Among them: During the abutting process between the first inclined plate 201 and the first drainage pipe 203, the pre-installation of the two splicing plates 1 can be completed, and at the same time, the rainwater leaking into the inner cavity of 101 can be diverted through the top structure of the first inclined plate 201.

[0034] As Figure 4 shown, a cone is provided in the middle groove of the annular fixing plate 302 in this embodiment. The cone provided in the middle of the annular fixing plate 302 facilitates the diversion of the collected rainwater and makes it flow towards the edge of the annular fixing plate 302; The outer ring surface of the annular fixing plate 302 is fixedly connected through a drainage pipe. Multiple groups of drainage pipes are provided corresponding to the inner cavities of one splicing plate 1 respectively, and the drainage pipes on the outer ring surface of the annular fixing plate 302 are in an inclined state.

[0035] As Figure 4 shown, the setting of the first spring 303 in this embodiment facilitates the timely reset of the first lower pressing plate 304. The second lower pressing plate 305 is in a frustum shape, and when the opposite sides of the first lower pressing plate 304 and the second lower pressing plate 305 abut against each other, they will form a structure similar to a "dish".

[0036] Specifically, since the waterproof layer at the top is damaged, the suction cups at the top of the first displacement column 301 will fail at this time. At this time, rainwater will penetrate downward along the joint of the splicing plate 1. Since the splicing plate 1 abuts against the first displacement column 301, when leakage occurs, the rainwater will flow downward along the outer ring surface of the first displacement column 301. When the rainwater flows to the annular fixing plate 302, since the annular fixing plate 302 has a groove structure, the rainwater will be temporarily stored inside the annular fixing plate 302. However, since a conical structure is provided in the middle of the annular fixing plate 302 and a diversion pipe is penetrated through the outer ring surface of the annular fixing plate 302, when the rainwater flows into the annular fixing plate 302, it will gather around the annular fixing plate 302 through the conical structure and flow into the cavity of the splicing plate 1 through the diversion pipe, and be discharged to the outside of the device through the first drainage pipe 203, thereby avoiding the situation of rainwater retention at the joints of multiple splicing plates 1 and further improving the overall waterproof performance of the device.

[0037] Among them: The setting of the annular fixing plate 302 can facilitate the fixing and loosening of the pressing buckle mechanism 3. At the same time, by using the internal conical structure and the diversion pipe thereof, the rainwater at the joints of multiple splicing plates 1 can be collected and diverted, and at the same time, it can prevent the rainwater from flowing into the bottom of the device and corroding the first spring 303, thereby improving the service life of the device. Embodiment 2

[0038] As Figures 1 to 7 shown, compared with Embodiment 1, another implementation manner of the present invention is: a waterproof method for the basement floor slab, and the specific steps include: Base treatment: Clean the upper and lower sides of the splicing plate 1 to ensure the flatness and smoothness of the base layers on the upper and lower sides of the splicing plate 1, and add a waterproof additional layer at the splicing plate 1; Waterproof layer laying: Lay the waterproof layer on the upper and lower sides of the splicing plate 1 to ensure the reliable connection between the waterproof material and the additional layer; Laying: Align the first inclined plate 201 between the two splicing plates 1 with the second inclined plate 202, and snap the second inclined plate 202 into the first inclined plate 201. Since the top of the first inclined plate 201 has an arc structure and wraps the top of the second inclined plate 202, there is no gap at the top of the assembly composed of the first inclined plate 201 and the second inclined plate 202 at this time. At the same time, since the arc structure at the top of the first inclined plate 201 is at the joint of the two splicing plates 1, when the waterproof layer on the splicing plate 1 leaks, the leaked water can be diverted.

[0039] Working principle: When the splicing plate 1 needs to be installed, since the downward pressing buckle mechanism 3 slides on the upper part of any splicing plate 1, when four splicing plates 1 need to be installed, first install the splicing plate 1 with the downward pressing buckle mechanism 3 on the top of the basement. At this time, manually move the part with the arc-shaped opening at the top of the other three splicing plates 1 to fit the outer ring surface of the first displacement column 301. At the same time, it is necessary to ensure that the four splicing plates 1 are on the same horizontal plane; At this time, manually press the first displacement column 301. Since the second lower pressing plate 305 is fixed at the bottom of the first displacement column 301, when the first displacement column 301 moves downward, the second lower pressing plate 305 will also move synchronously. At the same time, since the outer ring surface of the second lower pressing plate 305 is arc-shaped and inclined, when the outer ring surface of the second lower pressing plate 305 abuts against the inclined surface of the trapezoidal block 308, the trapezoidal block 308 will move along the guide of the limiting plate 306 to the side away from the first displacement column 301, and will synchronously drive the second displacement column 309 and the blocking plate 310 to move synchronously during the movement. At this time, the second spring 307 is in a compressed state; When the inclined surface of the second lower pressing plate 305 moves to the bottom of the trapezoidal block 308, the second spring 307 will reset because it is not blocked by an external force, and will drive the trapezoidal block 308 and the second displacement column 309 to move linearly along the guide of the limiting plate 306 during the reset. When the bottom of the trapezoidal block 308 contacts the top of the second lower pressing plate 305, the downward pressing buckle mechanism 3 will be fixed. Since the limiting plate 306 is fixed inside the second inclined plate 202, and the second inclined plate 202 is stuck inside the first inclined plate 201, when the first displacement column 301 is pressed downward, the splicing plate 1 can be quickly installed, which can reduce the time for manual adjustment and positioning, and thus improve the installation efficiency. At the same time, since the bottom of the suction cup at the top of the first displacement column 301 contacts the top of the four splicing plates 1 when the first displacement column 301 is not pressed, and the first displacement column 301 will adsorb on the top where the four splicing plates 1 meet after the first displacement column 301 performs the pressing work, when rainwater appears on the top of the splicing plate 1, the rainwater will flow out of the joint area along the edge of the suction cup, thereby improving the waterproof performance of the splicing plate 1.

[0040] When the splicing plate 1 encounters long-term rainfall, since the material of the splicing plate 1 will change in volume due to humidity or temperature changes, the waterproof layer on the top will be damaged at this time, and rainwater will penetrate inward along the joints of the splicing plate 1; Before the splicing plate 1 is installed with the downward pressing buckle mechanism 3, it will also be pre-fixed by the clamping connection between the first inclined plate 201 and the second inclined plate 202. When the first inclined plate 201 and the second inclined plate 202 are spliced, first insert the first drainage pipe 203 into the circular hole penetratingly opened inside the second inclined plate 202. At this time, the splicing plate 1 on the side with the second inclined plate 202 will move towards the first inclined plate 201, and will squeeze the first inclined plate 201 during the movement. Since the top of the second inclined plate 202 is lower than the top of the first inclined plate 201, and the first inclined plate 201 is made of flexible material, when the second inclined plate 202 moves towards the first inclined plate 201, it will squeeze the arc structure at the top of the first inclined plate 201. When the second inclined plate 202 enters the arc structure of the first inclined plate 201, the squeezed part will reset and wrap the top of the second inclined plate 202. Since the top of the first inclined plate 201 is directly below the gap between the two splicing plates 1, when rainwater leaks into the splicing plate 1 through the gap, it will be respectively diverted to the cavities of the adjacent splicing plates 1 through the first inclined plate 201, avoiding the accumulation of water at the gap or further penetration to the base layer, thus significantly reducing the leakage risk. Since the waterproof layer composed of multiple splicing plates 1 is in an inclined state, the water in the cavity of the splicing plate 1 will flow through the first drainage pipe 203 into the inner cavity of the last splicing plate 1 and be discharged through the drain pipe 204, thereby reducing the residence time of the infiltrated water in the cavity of the splicing plate 1 and enhancing the waterproof effect.

[0041] Among them: During the abutting process between the first inclined plate 201 and the first drainage pipe 203, the pre-installation of the two splicing plates 1 can be completed, and at the same time, the rainwater infiltrating into the inner cavity of 101 can be diverted through the top structure of the first inclined plate 201.

[0042] Due to the damage of the waterproof layer at the top, the suction cup at the top of the first displacement column 301 will fail at this time, and the rainwater will then penetrate downward along the joint of the splicing plate 1. Since the splicing plate 1 abuts against the first displacement column 301, when leakage occurs, the rainwater will flow downward along the outer ring surface of the first displacement column 301. When the rainwater flows to the annular fixing plate 302, since the annular fixing plate 302 has a groove structure, the rainwater will be temporarily stored inside the annular fixing plate 302. However, since a conical structure is provided in the middle of the annular fixing plate 302 and a diversion pipe is penetratingly provided on the outer ring surface of the annular fixing plate 302, when the rainwater flows into the annular fixing plate 302, it will converge towards the periphery of the annular fixing plate 302 through the conical structure and flow into the cavity of the splicing plate 1 through the diversion pipe and be discharged to the outside of the device through the first drainage pipe 203, thereby avoiding the situation of rainwater retention at the joints of multiple groups of splicing plates 1 and further improving the overall waterproof performance of the device.

[0043] Among them: The setting of the annular fixing plate 302 can facilitate the fixing and loosening of the pressing buckle mechanism 3. At the same time, by using its internal conical structure and the diversion pipe, the rainwater at the joints of multiple splicing plates 1 can be collected and diverted. Meanwhile, it can prevent the rainwater from flowing into the bottom of the device and corroding the first spring 303, thereby improving the service life of the device.
