Description

Technical Field

[0001] The invention relates to the technical field of drainage boards, in particular to a composite drainage board. Background Art

[0002] Plastic drainage board is made of polystyrene (HIPS) or polyethylene (HDPE) plastic base plate, which is stamped into conical bosses or convex points (or hollow cylindrical porous) with stiffening ribs. After continuous innovation and research and development, the raw materials have been greatly improved and changed. It is now pressed from polyvinyl chloride (PVC) as the raw material, and the compressive strength and overall flatness have been greatly improved. The width is 1~3 meters and the length is 4~10 meters or more. A layer of filtering geotextile is glued to the top surface of the conical boss to prevent soil particles from passing through, thereby avoiding the blockage of the drainage channel and making the drainage channel drain smoothly. The traditional drainage method uses bricks and tiles as the filter layer, uses more pebbles or gravel as the water filter layer, and drains the water to the designated location. Using drainage board instead of pebble water filter layer to drain water saves time, labor, energy, investment, and can also reduce the load of the building.

[0003] At present, during the installation process of drainage boards on the market, the rolled drainage boards are first laid on the ground. When the ground is large, multiple drainage boards need to be spliced. The splicing is generally performed by using a special welding machine for drainage boards to weld two sets of drainage boards, or using a flamethrower to heat the joints, and using the sticky characteristics of the plastic after heating and softening to fix and assemble the two sets of drainage boards. Then this assembly method requires a certain size of space to be reserved at the connection position of the drainage board. Therefore, after the drainage boards are assembled, the connection of the drainage boards will be relatively large. There is a large gap, and no drainage convex points are set at this gap position. During use, if geotextile is laid above this assembly position, the assembly position cannot provide support for the geotextile laid above, and the geotextile needs to be tightened and straightened here for use, and the drainage board is directly plugged in and assembled between the convex points. No fixed structure is set between the convex points at the plug-in assembly position, and the two sets of drainage board connection positions can be disassembled by simply pulling upwards, and the drainage board does not need to be disassembled after installation. Therefore, the practicality of this assembly method is also relatively poor.

[0004] For this reason, we propose a composite drainage board. Summary of the invention

[0008] As a further description of the above technical solution: the load-bearing structure is arranged on the surface of the top plate, and an expandable load-bearing plate and a filling plate are arranged on the surface of the top plate, and inserted into the clamping groove opened on the inner side of the top plate, so as to realize the assembly between multiple groups of drainage boards and improve the load-bearing strength of the drainage board; The load-bearing structure includes a cross-shaped slide rail separated from each other and opened on the surface of the top plate, a slide plate is slidably connected in the slide rail, the slide plate surface is connected to the load-bearing plate by an elastic rod, the load-bearing plate is provided with four independent groups, the bottom of the gap of the four groups of load-bearing plates is slidably connected to the filling plate by a limiting structure, the four groups of filling plates are an integrated cross-shaped, the bottom center position of the filling plate is fixedly connected to the bottom ring by a support rod, the surface of the bottom ring is connected to the bottom end of the protrusion by an elastic ring, the support rod is slidably inserted into the side wall of the protrusion, and the top end of the support rod passes through the through hole opened in the center position of the top plate to connect the filling plate, the bottom inner side of the top plate is provided with a clamping groove, and the clamping groove is provided with a clamping plate for clamping and fixing the load-bearing plate and the filling plate on both sides.

[0009] As a further description of the above technical solution: a limiting structure is arranged between the load-bearing plate and the filling plate, and is used to limit the movement trajectory of the filling plate between the gaps of the four groups of load-bearing plates; The limiting structure comprises a slide groove which is arranged at the middle position of both sides of the load-bearing plate, wherein a sliding block is slidably connected in the slide groove, and the sliding block is fixedly installed on the outer side of the filling plate.

[0010] As a further description of the above technical solution: the convex point and the top plate are both provided with cavities, the cavities in the convex point are vertically penetrating, and the cavities in the top plate are open at the bottom and closed at the top; The cavity with upper and lower through openings in the convex point is connected with the cavity with the bottom opening of the top plate, so that when assembling the drainage board, the top plate at the top of the lower convex point can be directly inserted into the upper convex point and the top plate, and fixedly assembled by inserting the load-bearing plate and the filling plate into the clamping groove opened on the inner side of the top plate.

[0012] As a further description of the above technical solution: the slide grooves on both sides of the load-bearing plate are inclined, and when the load-bearing plate slides downward and expands outward at the same time, they are adapted to the movement trajectory of the slider when the filling plate slides upward; The load-bearing plate will expand outwards while sliding downward, so that the filling plate will slide upward and be inserted into the gap of the load-bearing plate. At this time, the movement trajectory of the slider is inclined on both sides of the load-bearing plate. Therefore, the slide groove is set to adapt to the inclination of the slider trajectory, which will not limit the upward sliding of the filling plate.

Drainage boards are connected by plugging them between convex points, so as to avoid large spacing between two sets of drainage boards without support of convex points, and avoid the sinking of geotextile due to lack of support of convex points when laying geotextile on the surface of drainage boards, which affects drainage. At the same time, the load-bearing plate and the filling plate are expanded and plugged into the clamping groove opened in the top plate, so that multiple sets of drainage boards can be fixedly installed and cannot be disassembled.

[0014] 2. Install the drain boards by plugging them between the protruding points. You only need to adjust the position of the first set of drain boards when laying them.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1-Figure 10 The embodiment of the present invention provides a technical solution for a composite drainage board: it includes a bottom plate 1, and a plurality of groups of protrusions 2 are evenly spaced and penetrated on the surface of the bottom plate 1. The protrusions 2 are cylindrical with an isosceles trapezoidal cross section. The plurality of groups of protrusions 2 form a supporting structure of the drainage board, and also includes: a load-bearing structure arranged on the top of the protrusions 2. The load-bearing structure is expanded through the internally arranged load-bearing plates 3 and filling plates 4. When two groups of drainage boards are assembled, the protrusions 2 are plugged in, and the load-bearing plates 3 and the filling plates 4 are plugged in the clamping grooves 5 opened on the inner side of the top plate 9 to realize the assembly and fixation of the two groups of drainage boards.

[0023] In another embodiment provided by the present invention, preferably, a supporting structure is installed on the top of the protrusion 2, and a plurality of groups of protrusions 2 are evenly spaced, and a top plate 9 is arranged on the top of the protrusion 2, so as to provide load-bearing strength to the drainage board. The supporting structure includes a plurality of groups of protrusions 2 evenly spaced on the surface of the base plate 1, and the top plate 9 is fixedly connected to the top of the protrusion 2, and a load-bearing structure is arranged on the surface of the top plate 9.

[0024] In another embodiment provided by the present invention, a load-bearing structure is arranged on the surface of the top plate 9. By arranging an expandable load-bearing plate 3 and a filling plate 4 on the surface of the top plate 9 and inserting them into a clamping groove 5 opened on the inner side of the top plate 9, the assembly between multiple groups of drainage plates is realized, and the load-bearing strength of the drainage plates is improved. The load-bearing structure includes a cross-shaped slide rail 13 separated from each other opened on the surface of the top plate 9, and a slide plate 12 is slidably connected in the slide rail 13. The surface of the slide plate 12 is connected to the load-bearing plate 3 through an elastic rod 11. The load-bearing plate 3 is provided with four independent The bottom of the gap of the four groups of load-bearing plates 3 is slidably connected with a filling plate 4 through a limiting structure. The four groups of filling plates 4 are an integrated cross-shaped. The bottom center position of the filling plate 4 is fixedly connected to the bottom ring 7 through a support rod 6. The surface of the bottom ring 7 is connected to the bottom end of the protrusion 2 through an elastic ring 8. The support rod 6 is slidably inserted into the inside of the side wall of the protrusion 2, and the top of the support rod 6 passes through the through hole 14 opened in the center position of the top plate 9 to connect the filling plate 4. A clamping groove 5 is opened at the bottom inner side of the top plate 9, and a clamping plate 18 for clamping and fixing the load-bearing plate 3 and the filling plate 4 on both sides is opened in the clamping groove 5.

[0025] In another embodiment provided by the present invention, a limiting structure is arranged between the load-bearing plate 3 and the filling plate 4, and is used to limit the movement trajectory of the filling plate 4 between the gaps of the four groups of load-bearing plates 3. The limiting structure includes a slide groove 17 opened in the middle position of both sides of the load-bearing plate 3, and a slider 16 is slidably connected in the slide groove 17, and the slider 16 is fixedly installed on the outside of the filling plate 4.

[0026] In another embodiment provided by the present invention, a cavity 10 is provided in both the protrusion 2 and the top plate 9. The cavity 10 in the protrusion 2 is a vertical through-type, and the cavity 10 in the top plate 9 is open at the bottom and closed at the top. The vertical through-type cavity 10 provided in the protrusion 2 is connected with the cavity 10 at the bottom of the top plate 9, so that when assembling the drainage board, the top plate 9 at the top of the lower protrusion 2 can be directly inserted into the upper protrusion 2 and the top plate 9, and fixedly assembled by inserting the load-bearing plate 3 and the filling plate 4 into the clamping groove 5 provided on the inner side of the top plate 9.

[0027] In another embodiment provided by the present invention, the bottom of both sides of the load-bearing plate 3 is arranged to be inclined with the top end protruding outward and the bottom end recessed inward, so as to accommodate the upward squeezing and sliding of the filling plate 4 between the gaps of multiple groups of load-bearing plates 3. The bottom of both sides of the load-bearing plate 3 is arranged to be inclined, so that the filling plate 4 can slide upward along the edge of the inclined load-bearing plate 3 while sliding the filling plate 4 upward to fill the gaps of the load-bearing plates 3, thereby facilitating the upward sliding of the filling plate 4.

[0028] In another embodiment provided by the present invention, the slide grooves 17 opened on both sides of the load-bearing plate 3 are inclined. When the load-bearing plate 3 slides downward and expands outward at the same time, it is adapted to the movement trajectory of the slider 16 when the filling plate 4 slides upward. The load-bearing plate 3 will expand outward while sliding downward, so that the filling plate 4 can be slid upward and inserted into the gap of the load-bearing plate 3. At this time, the movement trajectory of the slider 16 is inclined on both sides of the load-bearing plate 3. Therefore, the slide groove 17 is set to adapt to the inclined shape of the trajectory of the slider 16, and will not limit the upward sliding of the filling plate 4.

[0029] When the drainage board is produced and sold, it is generally necessary to roll it up for storage and transportation. Therefore, when rolling it up, a secondary limit fixation will be provided for the rolled drainage board: First fixation: when the bottom plate 1 drives the convex point 2 to roll up, the convex point 2 is placed in the cavity 10 inside the convex point 2 set on the bottom plate 1. At this time, when the convex point 2 of the rear section is inserted into the cavity 10 of the convex point 2 of the front section, when it is inserted to a certain extent, the inner wall of the cavity 10 will squeeze the load-bearing plate 3 due to its own size, and the load-bearing plate 3 is expanded to a certain extent to cooperate with the inner wall of the cavity 10 to squeeze the outer side of the load-bearing plate 3, so that the convex point 2 is inserted into the corresponding cavity for fixed position; Second fixation: During the process of continuous winding of the drain board, after the drain board of the previous circle is inserted into the cavity 10 for limiting by the protrusion 2, when the next circle of the drain board is wound, the drain board of the next circle will squeeze the bottom ring 7, and the bottom ring 7 squeezes the elastic ring 8, so that the filling plate 4 is lifted up by the support rod 6 and inserted into the gap between the multiple groups of load-bearing plates 3 that are unfolded to a certain extent, and the load-bearing plate 3 that has been fixed for the first time can be further expanded outward with the filling plate 4 through the squeezing of the bottom ring 7 by the next circle of the drain board, so that the connection between the outer circle of the load-bearing plate 3 and the inner wall of the cavity 10 is tightened; The rolled-up drain board is reinforced twice to fix the rolled-up drain board, so that the rolled-up drain board only needs to be simply bound, which is convenient for rolling up and storing the drain board. Compared with the common drain board, the rolled-up drain board is more compact and occupies less storage and transportation space. After the rolled-up drain board is transported to the position where it is needed, the drain board is unrolled, and the drain board can be laid at the position where it is needed. When installing and assembling multiple rolls of drain boards, it is only necessary to place the previous set of drain boards in position, and then insert the convex points 2 of the first row of the next set of drain boards into the convex points 2 at the end of the previous set of drain boards. The laying position of the next set of drain boards is restricted by the plugging between the convex points 2 here, so that it is only necessary to unroll and lay the other end, and there is no need to adjust the position of the drain board for laying. After the laying is completed, the protrusions 2 at the connection position are hammered down with a rubber hammer or the user directly steps on them to fix the two groups of protrusions 2 together. When the upper protrusion 2 is hammered down, the cavity 10 in the upper protrusion 2 is inserted into the lower protrusion 2. During the hammering process, the protrusions 2 of the lower drainage board will be completely inserted into the upper protrusions 2 until the load-bearing plate 3 and the filling plate 4 reach the position of the clamping groove 5 opened on the inner side of the top plate 9. At this time, the load-bearing plate 3 is squeezed from the top, and the filling plate 4 is squeezed from the bottom ring 7 and the support rod 6, so that the load-bearing plate 3 is pressed on the elastic rod Under the restriction of the slide rail 13, the slide plate 11 and the slide plate 12 expand outward and are inserted into the clamping groove 5. The two groups of clamping plates 18 arranged in the clamping groove 5 clamp and fix the two sides of the load-bearing plate 3, thereby achieving the fixation of the load-bearing plate 3 in the clamping groove 5. At the same time, the filling plate 4 is restricted by the slider 16 and the slide groove 17 to fill the gap after the expansion of the load-bearing plate 3, thereby increasing the contact area between the top of the protrusion 2 and the heavy object on the surface of the drainage board, and using the physical principle that when the contact area increases, the same force can produce a smaller pressure, thereby increasing the load-bearing capacity of the drainage board; At the same time, the elastic ring 8 with elastic deformation ability connected to the bottom end of the bottom ring 7 and the convex point 2 can provide a certain buffering capacity between the convex point 2 and the bottom ring 7, thereby providing a certain buffering force for the convex point 2 during the load-bearing process, thereby increasing the load-bearing strength of the drainage board; The expansion and contraction of the load-bearing plate 3 and the filling plate 4 can achieve various effects: The first method: the drainage board is installed by plugging between the convex points 2. It is only necessary to adjust the position of the first set of drainage boards when paving. The subsequent drainage boards can be laid on the bracket only after being fixed between the convex points 2. It is not necessary to adjust the position and then align and fix the two sets of drainage boards. The second method is to connect the drainage boards through the protrusions 2, so as to avoid the large spacing between the two sets of drainage boards without the support of the protrusions 2, and to avoid the sinking of the geotextile due to the lack of support of the protrusions 2 when the geotextile is laid on the surface of the drainage board, which affects the drainage use. The third method: by expanding the load-bearing plate 3 and the filling plate 4, the contact area of ​​the drainage board when bearing the load is increased, thereby increasing the load-bearing capacity of the drainage board; The fourth method: by expanding the load-bearing plate 3 and the filling plate 4 and plugging them into the clamping groove 5 opened in the top plate 9, multiple sets of drainage plates can be fixedly installed and cannot be disassembled; The fifth method: through the load-bearing plate 3 and the filling plate 4, the drainage board is doubly fixed and tightened during the rolling storage and transportation process, so as to better roll up the drainage board; The drain board and the load-bearing board 3 are mainly used to improve the load-bearing capacity of the drain board, and at the same time produce an additional unexpected effect: a double reinforcement effect can be provided for the non-detachable assembly between the drain boards.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
