Description

A polymer self-adhesive waterproof and drainage structure Technical Field

[0001] This utility model relates to the field of drainage, and more particularly to the field of self-adhesive drainage technology, specifically referring to a polymer self-adhesive waterproof and drainage structure. Background Technology

[0002] Currently, drainage engineering is widely used in building construction, including the upper or lower layers of building foundations, the interior and exterior walls of basements, and roof waterproofing and insulation layers; in transportation engineering, it is used for highway and railway subgrades, embankments, and slope protection layers; in landscaping, it is used for garage roof greening, roof gardens, football fields, and golf courses; and in municipal engineering, it is used for road subgrades and subway tunnels.

[0003] Traditional drainage methods use bricks and tiles as a filter layer and pebbles or gravel as a water filtration layer to drain water to a designated location. However, the widespread use of plastic drainage boards to replace the pebble filtration layer saves time, labor, and energy, reduces investment, and lowers the load on buildings.

[0004] Existing drainage boards consist of solid or cup-shaped protrusions formed on a polymer sheet. The opening of the cup-shaped protrusion is in the opposite direction of the protrusion, which generally faces upwards. The space between the protrusions forms a drainage channel. When the protrusions face downwards, holes are punched between them, and water passes through these holes and then flows away through the space between the protrusions.

[0005] Chinese utility model patent application number CN202120790872.8 discloses a self-adhesive sealing drainage structure, but this drainage structure alone does not provide a firm connection between adjacent drainage units. Summary of the Invention

The bottom surface of the upper splicing layer is bonded to the top surface of the two substrates. The width of the lower splicing layer is adapted to the width between the two substrates. The side surface of the lower splicing layer is bonded to the corresponding substrate and the waterproof layer.

[0010] This preferred solution achieves the connection between two substrates by setting the upper layer, and achieves the connection between the substrate and the side of the waterproof layer by setting the lower layer, thereby enhancing the connection strength of the two drainage units. At the same time, a bent adhesive surface is formed between the splicing block and the substrate and waterproof layer of the drainage unit, thereby enhancing the waterproofness between the two drainage units.

[0011] Preferably, the lower end of the waterproof layer is provided with a bottom splicing layer connecting the two waterproof layers, and the bottom surface of the bottom splicing layer is bonded to the bottom splicing layer.

[0012] In use, this preferred solution connects two drainage units from the bottom of the drainage unit by setting a bottom layer, thereby further enhancing the connection strength between the two drainage units.

[0014] This preferred solution achieves the connection between the bottom layer and the waterproof layer through the setting of bottom layer bonding.

[0015] Preferably, a sinking groove is provided on the bottom layer, and a sinking block inserted into the sinking groove is fixed to the bottom surface of the lower layer.

[0016] This preferred solution achieves the positioning and connection of the bottom layer and the lower layer by setting up a sinking trough and sinking blocks.

[0017] Preferably, the substrate has a groove located at the lower end of the upper panel, and a protrusion inserted into the groove is fixed to the bottom surface of the upper panel. The bottom and side surfaces of the protrusion are bonded to the bottom and side surfaces of the groove.

[0018] This preferred solution facilitates the positioning and connection of the upper panel and the substrate by using bumps and grooves.

[0019] Preferably, the intermediate layer includes an intermediate block, and the two sides of the intermediate block are provided with connecting grooves for inserting the filter layer, and the filter layer is adhered in the connecting grooves.

[0020] In this preferred embodiment, the connection slot on the middle block facilitates the connection of the two filter layers.

[0021] The beneficial effects of this utility model are as follows: the filter layer is connected by an intermediate layer, and the substrate is bonded by splicing blocks, thereby enhancing the connection strength between two adjacent drainage units; the upper splicing layer enables the connection between two substrates, and the lower splicing layer enables the connection between the substrate and the side of the waterproof layer, thereby enhancing the connection strength between the two drainage units; at the same time, a bent adhesive layer is formed between the splicing blocks and the substrate and waterproof layer of the drainage unit, thereby enhancing the waterproofness between the two drainage units.

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0026] Referring to Figure 1, the present invention discloses a polymer self-adhesive waterproof structure, comprising several drainage units arranged in rows and columns. Each drainage unit includes a boss, a filter layer 1, a substrate 2, and a waterproof layer 3. The filter layer 1 is adhered to the top surface of the boss, and the bottom surface is connected to the substrate 2. The bottom surface of the substrate 2 is connected to the ground through the waterproof layer 3. Both the top and bottom surfaces of the waterproof layer 3 have adhesive properties and are existing technologies.

[0027] The drainage structure also includes a connection structure connecting two adjacent drainage units. The connection structure includes an intermediate layer connecting two filter layers 1 and a splicing block for bonding two substrates 2.

[0028] The splicing block includes an upper splicing layer 5 and a lower splicing layer 6 connected to the bottom surface of the upper splicing layer 5. The bottom surface of the upper splicing layer 5 is bonded to the top surface of the two substrates 2. The width of the lower splicing layer 6 is adapted to the width between the two substrates 2. The side surface of the lower splicing layer 6 is bonded to the corresponding substrate 2 and the waterproof layer 3.

[0029] The lower end of the waterproof layer 3 is also provided with a bottom splicing layer 7 that connects the two waterproof layers 3, and the bottom surface of the bottom splicing layer 6 is bonded to the bottom splicing layer 7.

[0030] The top surface of the bottom layer 7 is bonded to the bottom surface of the waterproof layer 3, and the top surface of the bottom layer 7 is also bonded to the bottom surface of the lower layer 6. The bottom surface of the bottom layer 7 is bonded to the ground. A recessed groove is formed on the bottom layer 7, and a sinker 8 inserted into the recessed groove is fixed to the bottom surface of the lower layer 6.

[0031] The substrate 2 has a groove located at the lower end of the upper panel 5. A protrusion 9 inserted into the groove is fixed to the bottom surface of the upper panel 5. The bottom and side surfaces of the protrusion 9 are bonded to the bottom and side surfaces of the groove.

[0032] The intermediate layer includes an intermediate block 4, and the intermediate block 4 has connecting grooves on both sides for inserting the filter layer 1. The filter layer 1 is adhered in the connecting grooves.

[0033] The splicing blocks, protrusions 9, sinkers 8, and bottom splicing layer 7 are all made of the same material as the waterproof layer 3, and the top and sides of the upper splicing blocks are provided with self-adhesive layers.

[0034] Meanwhile, since water affects the adhesive's stickiness, the design of upper, lower, and bottom layers increases the length of the bonding surface, effectively increasing the service life.

[0035] In use, the bottom layer 7 is bonded to the bottom surface of the waterproof layer 3 of two adjacent drainage units, and then the sinker 8 of the lower layer 6 is inserted into the sinker groove. At the same time, the bottom surface of the upper layer 5 is bonded to the top surface of the substrate 2, and the protrusion 9 is inserted into the groove, thereby realizing the bottom connection between the two adjacent drainage units. Then, glue is applied to the connecting groove, and the filter layer 1 is inserted into the connecting groove of the middle block 4 and bonded.
