Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a drainage board. Background Technology

[0002] Traditional drainage methods involve using bricks and tiles as a filter layer and a large amount of pebbles or gravel as a filtration layer to drain water. Gravel, due to its good drainage performance and certain load-bearing capacity, is widely used in the drainage layer of garage roofs. In garage roof design, a gravel layer is used to replace soil or other materials as a drainage and filtration layer above the waterproof layer. However, this drainage method for garage roofs also has drawbacks. For example, garage roofs rely on gravity flow for drainage. If the drainage layer is not smooth, gravity flow is unlikely to drain the accumulated water, leading to prolonged waterlogging. Water accumulation in the soil increases the load on the garage roof in a short period. If water cannot drain promptly, the continuous hydrostatic pressure on the waterproof layer can cause pressure soaking, easily leading to water leakage. Over time, leaks will appear in the waterproof layer, and water accumulation can also cause soil saturation, plant root rot, and death, affecting the greening rate. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a drainage board with a simple structure, convenient installation, improved load-bearing strength, and better drainage effect, effectively removing infiltrated water from the soil. To achieve the above objective, the technical solution of this utility model is as follows:

[0005] The base plate is provided with multiple cup-shaped protrusions with upward openings. The bottom of the cup-shaped protrusions is lower than the main body of the base plate. Each cup-shaped protrusion has an annular baffle at its opening. Each annular baffle has four U-shaped notches, which are arranged in a cross shape.

[0006] The plurality of cup-shaped protrusions are arranged in a matrix. Two ribs are provided between the U-shaped notches of two adjacent annular baffles in the same row. The two ribs form a first groove, so that two adjacent cup-shaped protrusions in the same row can be connected through the first groove. Two ribs are provided between the U-shaped notches of two adjacent annular baffles in the same column. The two ribs form a second groove, so that two adjacent cup-shaped protrusions in the same column can be connected through the second groove.

[0007] The upper surface of the base plate is provided with a strip-shaped groove or a strip-shaped protrusion, and the lower surface of the base plate is provided with a strip-shaped protrusion or a strip-shaped groove. The strip-shaped groove is located at one end of the base plate, and the strip-shaped protrusion is located at the other end of the base plate, so that two adjacent base plates can be overlapped by the strip-shaped protrusion and the strip-shaped groove.

[0008] The cup-shaped protrusion is also filled with the concrete block, and the top of the concrete block has a recessed groove, which is cross-shaped and used to connect the four U-shaped openings.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the drainage board of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0031] Reference Figures 1 to 3 The drainage board of this utility model is used for drainage of garage roof slab. The drainage board includes a base plate 101, multiple reinforcing bars 102 and concrete blocks 103.

[0032] The base plate 101 is provided with multiple cup-shaped protrusions 1011 with upward openings. The bottom of the cup-shaped protrusions 1011 is lower than the main body of the base plate 101. Each cup-shaped protrusion 1011 has an annular baffle 1012 at its opening. Each annular baffle 1012 has four U-shaped notches 1013. The four U-shaped notches 1013 are arranged in a cross shape.

[0033] Multiple cup-shaped protrusions 1011 are arranged in a matrix. Two ribs 102 are provided between the U-shaped notches 1013 of two adjacent annular baffles 1012 in the same row. The two ribs 102 form a first groove 1014, so that two adjacent cup-shaped protrusions 1011 in the same row can be connected through the first groove 1014. Two ribs 102 are provided between the U-shaped notches 1013 of two adjacent annular baffles 1012 in the same column. The two ribs 102 form a second groove 1015, so that two adjacent cup-shaped protrusions 1011 in the same column can be connected through the second groove 1015.

[0034] Figure 1 and Figure 2 In the design, six cup-shaped protrusions 1011 are arranged in a matrix of two rows and three columns. In other embodiments, other numbers of rows and columns can be used in the matrix arrangement, and the number of rows and columns can also be the same. The base plate 101 can be rectangular, and the openings of the cup-shaped protrusions 1011 can be circular or square.

[0035] The upper surface of the base plate 101 is provided with a strip-shaped groove 1016 or a strip-shaped protrusion 1017, and the lower surface of the base plate 101 is provided with a strip-shaped protrusion 1017 or a strip-shaped groove 1016. The strip-shaped groove 1016 is located at one end of the base plate 101, and the strip-shaped protrusion 1017 is located at the other end of the base plate 101, allowing two adjacent base plates 101 to overlap using the strip-shaped protrusion 1017 and the strip-shaped groove 1016. The strip-shaped groove 1016 and the strip-shaped protrusion 1017 are located on different surfaces of the base plate 101. When two adjacent base plates 101 overlap, the strip-shaped protrusion 1017 of one base plate 101 embeds into the strip-shaped groove 1016 of the other base plate 101. This arrangement achieves a reliable overlap and is convenient and quick to install.

[0036] The cup-shaped protrusion 1011 is also filled with concrete blocks 103. For example... Figure 3 As shown, the top of the concrete block 103 has a recessed groove 1031, which is cross-shaped and used to connect the four U-shaped openings 1013. The recessed groove 1031 on the concrete block 103 ensures the load-bearing strength of the drainage board while facilitating drainage.

[0037] In a preferred embodiment, along the length of the rows, two ribs 102 are also provided at the outer U-shaped notch 1013 of each annular baffle 1012 in the first and last rows, forming a third groove 1018. Along the length of the columns, two ribs 102 are also provided at the outer U-shaped notch 1013 of each annular baffle 1012 in the first and last columns, forming a fourth groove 1019.

[0038] In this configuration, along the length of the row, one end of the base plate 101 containing the strip-shaped protrusion 1017 is the first end of the base plate 101 along the length of the row. The rib 102 at the first end of the base plate 101 along the length of the row is flush with the end of the first end of the base plate 101 along the length of the row. The distance between the end of the first end of the base plate 101 along the length of the row and the strip-shaped protrusion 1017 is L1. In other words, the distance between the outer end of the rib 102 at the first end of the base plate 101 along the length of the row and the strip-shaped protrusion 1017 along the length of the row is L1.

[0039] One end of the base plate 101 containing the strip-shaped groove 1016 is the second end of the base plate 101 along its length in the row direction. The distance between the rib 102 at the second end of the base plate 101 along its length in the row direction and the strip-shaped groove 1016 is L2, where L1 = L2. This allows the ribs 102 on the two adjacent base plates 101 to abut against each other when they overlap. The abutment can be sealed with adhesive.

[0040] Along the length of the column, one end of the base plate 101 where the strip-shaped protrusion 1017 is located is the first end of the base plate 101 along the length of the column. The rib 102 of the first end of the base plate 101 along the length of the column is flush with the end of the first end of the base plate 101 along the length of the column. The distance between the end of the first end of the base plate 101 along the length of the column and the strip-shaped protrusion 1017 is L3. That is, the distance between the outer end of the rib 102 of the first end of the base plate 101 along the length of the column and the strip-shaped protrusion 1017 along the length of the column is L3.

[0041] One end of the base plate 101 containing the strip-shaped groove 1016 is the second end of the base plate 101 along the length of the column. The distance between the rib 102 at the second end of the base plate 101 along the length of the column and the strip-shaped groove 1016 is L4. Where L3 = L4, this allows the ribs 102 on the two adjacent base plates 101 to abut against each other when they overlap. The abutment can also be sealed with adhesive.

[0042] The third groove 1018 and the fourth groove 1019 are provided to facilitate drainage by overlapping the base plate 101 and to improve the support strength of the base plate, which is beneficial for supporting the geotextile above. The top ends of the reinforcing bars 102 and the annular retaining bars 1012 may also be provided with protrusions for supporting the geotextile. There are multiple protrusions, which are spaced apart.

[0043] When the base plate 101 is rectangular, both the first and second sides of the base plate 101 can be provided with strip-shaped grooves 1016, and both the third and fourth sides of the base plate 101 can be provided with strip-shaped protrusions 1017. This makes it easier to quickly and reliably overlap the base plates 101. When two adjacent base plates 101 overlap, the strip-shaped grooves 1016 and strip-shaped protrusions 1017 can also be glued together, which can further ensure the reliability of the overlap and also facilitate waterproofing.

[0044] Preferably, there can be multiple strip-shaped grooves 1016 and multiple strip-shaped protrusions 1017, with one-to-one correspondence between the number of strip-shaped grooves 1016 and the number of strip-shaped protrusions 1017. Multiple strip-shaped grooves 1016 and multiple strip-shaped protrusions 1017 are spaced apart on the same straight line. Providing multiple strip-shaped grooves 1016 and strip-shaped protrusions 1017 is more conducive to the connection and fixation between the base plates 101, and results in better waterproofing.

[0045] Preferably, the ribs 102 of the first groove 1014 and / or the second groove 1015 are provided with notches, the bottom of which is higher than the upper surface of the base plate 101. That is, notches can be provided in the ribs 102 of the first groove 1014, or in the ribs 102 of the second groove 1015, or both ribs 102 of the first groove 1014 and the second groove 1015 can have notches. This arrangement facilitates drainage and also provides some water retention, which is more conducive to the growth of the upper green plants. The notches can be U-shaped, and multiple notches can be spaced apart on a single rib 102.

[0046] The cup-shaped protrusions 1011, ribs 102, annular baffles 1012, strip grooves 1016, and strip protrusions 1017 on the main body of the base plate 101 can all be integrally molded with the main body of the base plate 101, thus making the drainage board a one-piece molded structure. The drainage board can be made of plastic material, or other waterproof materials.

[0047] The finished drainage board has the following requirements: height 20mm; compressive strength ≥230KPa; longitudinal water flow ≥12.5cm / s; unit mass ≥1000g / ㎡.

[0048] The height of the drainage board is 20mm, which means the vertical distance between the highest and lowest points of the drainage board is 20mm, and the thickness of the drainage board is 20mm.

[0049] The drainage boards described in the above embodiments have a simple structure, improved load-bearing strength, better drainage effect, and convenient installation. They can effectively drain infiltrated water from the soil, have lower cost, wider applicability, better construction quality, and save construction costs. The addition of concrete blocks improves the load-bearing strength of the drainage board. The cross-shaped grooves in the concrete are connected to the first, second, third, and fourth grooves, effectively ensuring smooth drainage. The gaps between adjacent cup-shaped protrusions of the drainage board form effective drainage channels, further ensuring unobstructed drainage. The space between the first and second grooves can play a certain role in water storage, which is more conducive to the growth of the upper green plants. Using this utility model of waterproof board effectively solves the hidden defects of traditional garage roof drainage systems. The drainage board has functions such as creating in-layer drainage, draining infiltrated water from the soil, preventing plant root penetration, guiding and draining accumulated water within the layer, heat insulation, vibration isolation, and soft protection for the roll waterproofing system. It ensures construction quality, improves construction efficiency, reduces project costs, and saves resources. The drainage board can be widely used in the drainage layer of garage roofs.

[0050] It should be noted that, unless otherwise specified, the above embodiments and features can be combined with each other.

[0051] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
