Description

Technical Field

[0001] The present invention relates to the technical field of drainage plates, and specifically to a composite drainage plate. Background Art

[0002] Plastic drainage plates are made of polystyrene (HIPS) or polyethylene (HDPE) as raw materials. The plastic bottom plate is stamped into conical protrusions or convex points with stiffening ribs (or hollow cylindrical porous). Through continuous innovation and research and development, the raw materials have been greatly improved and changed. Now they are pressed from polyvinyl chloride (PVC). 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 filter geotextile is adhesively bonded to the top surface of the conical protrusion to prevent soil particles from passing through, thus avoiding blockage of the drainage channel and ensuring smooth drainage of the pore. The traditional drainage method uses bricks, stones and tiles as the filter layer, uses a large amount of cobblestones or gravel as the water filter layer, and drains the water to a designated location. Using drainage plates to replace the cobblestone water filter layer for drainage saves time, effort, energy, investment, and can also reduce the load of the building.

[0003] Currently, during the installation of drainage plates on the market, the rolled drainage plates are first laid on the ground. When the ground area is large, it is necessary to splice multiple drainage plates. Generally, a special welding machine for drainage plates is used to weld between two groups of drainage plates, or a blowtorch is used to heat the connection point, and the two groups of drainage plates are fixedly assembled using the characteristic that plastic softens and becomes sticky when heated. Then, this assembly method requires leaving a certain size of space at the connection position of the drainage plates. Therefore, after the drainage plates are assembled, there will be a large gap at the connection of the drainage plates, and no drainage convex points are provided at this gap position. During use, when geotextiles or the like are laid above this assembly position, the assembly position cannot provide support for the geotextiles laid above, and the geotextiles or the like need to be tightened and straightened here. Directly inserting and assembling between the convex points of the drainage plates, there is no fixed structure between the convex points at the insertion and assembly position, and the connection position of the two groups of drainage plates can be disassembled by simply pulling upward. However, the drainage plates do not need to be disassembled after installation. Therefore, the practicality of this assembly method is also relatively poor.

[0004] Therefore, we propose a composite drainage plate. Summary of the Invention

[0005] The purpose of the present invention is to provide a composite drainage plate to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: including a bottom plate, on the surface of which a plurality of groups of bumps are uniformly and spacedly penetrated. The bumps are cylinders with an isosceles trapezoid cross-section. The plurality of groups of bumps form a support structure for the drainage plate. It further includes: a load-bearing structure arranged at the top of the bumps. When two drainage plates are assembled, the bumps are inserted into each other through the expansion between the load-bearing plate and the filling plate arranged inside, and the load-bearing plate and the filling plate are inserted into the clamping grooves opened inside the top plate, so as to realize the assembly and fixation of the two drainage plates.

[0007] As a further description of the above technical solution: the support structure is installed at the top of the bumps. By a plurality of groups of bumps uniformly and spacedly arranged and a top plate arranged at the top of the bumps, the load-bearing strength of the drainage plate is provided.

[0008] The support structure includes a plurality of groups of bumps uniformly and spacedly arranged on the surface of the bottom plate. The top of the bumps is fixedly connected with a top plate, and a load-bearing structure is arranged on the surface of the top plate.

[0009] As a further description of the above technical solution: the load-bearing structure is arranged on the surface of the top plate. By arranging an expandable load-bearing plate and a filling plate on the surface of the top plate and inserting them into the clamping grooves opened inside the top plate, the assembly between multiple drainage plates is realized, and at the same time, the load-bearing strength of the drainage plate is improved.

[0010] The load-bearing structure includes mutually separated slide rails in a cross shape opened on the surface of the top plate. A sliding plate is slidably connected in the slide rails. The surface of the sliding plate is connected with a load-bearing plate through an elastic rod. There are four mutually independent groups of load-bearing plates. The bottom of the gap between the four groups of load-bearing plates is slidably connected with a filling plate through a limiting structure. The four filling plates are integrally in a cross shape. The center position of the bottom of the filling plate is fixedly connected with a bottom ring through a support rod. The surface of the bottom ring is connected with the bottom end of the bump through an elastic ring. The support rod is slidably inserted into the side wall inside the bump, and the top end of the support rod penetrates through a through hole opened at the center position inside the top plate to connect the filling plate. Clamping grooves are opened at the bottom inside the top plate, and clamping plates for clamping and fixing the two sides of the load-bearing plate and the filling plate are opened in the clamping grooves.

[0011] As a further description of the above technical solution: the limiting structure is arranged between the load-bearing plate and the filling plate and is used to provide a limit for the movement track of the filling plate between the gaps of the four groups of load-bearing plates.

[0012] The limiting structure includes sliding grooves opened at the middle positions on both sides of the load-bearing plate. A sliding block is slidably connected in the sliding grooves, and the sliding block is fixedly installed on the outside of the filling plate.

[0013] As a further description of the above technical solution: cavities are opened in both the bump and the top plate. The cavity in the bump is a through type from top to bottom, and the cavity in the top plate is in a shape with an open bottom and a closed top.

[0014] The cavity with an upper and lower through-opening in the bump communicates with the cavity with an opening at the bottom of the top plate, enabling the top plate at the top of the lower bump to be directly inserted into the upper bump and the top plate during the assembly of the drainage board, and being fixedly assembled by inserting the load-bearing plate and the filling plate into the clamping groove formed on the inner side of the top plate.

[0015] As a further description of the above technical solution: The bottoms of both sides of the load-bearing plate are arranged in an inclined shape with the top protruding outward and the bottom recessed inward to adapt to the upward extrusion and sliding of the filling plate between the gaps of multiple load-bearing plates;

[0016] Arranging the bottoms of both sides of the load-bearing plate in an inclined shape can enable the filling plate to slide upward along the edge of the inclined load-bearing plate while sliding upward to fill the gap of the load-bearing plate, facilitating the upward sliding of the filling plate.

[0017] As a further description of the above technical solution: The sliding grooves formed on both sides of the load-bearing plate are inclined, and are adapted to the movement trajectory of the slider when the filling plate slides upward while the load-bearing plate slides downward and expands outward at the same time;

[0018] When the load-bearing plate slides downward, it will expand outward, thereby inserting the filling plate upward 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, setting the sliding groove in an inclined shape adapted to the slider trajectory will not limit the upward sliding of the filling plate.

[0019] In the above technical solution, a composite drainage board provided by the present invention has the following beneficial effects:

[0020] 1. By inserting the drainage boards through the connection between the bumps, the connection between two groups of drainage boards can avoid a large gap without the support of bumps, preventing the geotextile from sinking at the connection of the drainage boards due to the lack of bump support when laying the geotextile on the surface of the drainage board, which affects drainage use. At the same time, through the expansion and insertion of the load-bearing plate and the filling plate into the clamping groove formed in the top plate, the fixed installation of multiple groups of drainage boards is realized and cannot be disassembled.

[0021] 2. Installing the drainage board by inserting through the connection between the bumps only requires adjusting the position during the paving of the first group of drainage boards. For subsequent drainage boards, only after being fixed through the connection between the bumps can they be directly laid, without the need to adjust the position and then align and fix the two groups of drainage boards.

[0022] 3. Through the expansion of the load-bearing plate and the filling plate, the contact area when the drainage board bears weight is increased, and the load-bearing capacity of the drainage board is increased.

[0023] 4. Through the load-bearing plate and the filling plate, the drainage plate is doubly fixed and tightened during winding, storage and transportation, so as to better wind the drainage plate.

[0024] 5. The drainage plate and the load-bearing plate are mainly used to improve the load-bearing capacity of the drainage plate, and at the same time produce an additional unexpected effect: they can provide a double reinforcement effect for the non-detachable assembly between the drainage plates.

Detailed implementation manners

[0038] 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 introduced in detail below in conjunction with the accompanying drawings.

[0039] Please refer to Figures 1-10 , an embodiment of the present invention provides a technical solution for a composite drainage plate: including a bottom plate 1, on the surface of the bottom plate 1, a plurality of groups of protruding points 2 are uniformly and spacedly penetrated. The protruding points 2 are cylinders with an isosceles trapezoid cross-section. The plurality of groups of protruding points 2 form a support structure for the drainage plate. It further includes: a load-bearing structure arranged at the top of the protruding points 2. Through the expansion between the load-bearing plate 3 and the filling plate 4 arranged inside, when two drainage plates are assembled, the protruding points 2 are inserted into each other, and the load-bearing plate 3 and the filling plate 4 are inserted into the clamping groove 5 opened inside the top plate 9 to realize the assembly and fixation of the two drainage plates.

[0040] In another embodiment provided by the present invention, preferably, the support structure is installed at the top of the protruding points 2. By a plurality of groups of protruding points 2 arranged at equal intervals and a top plate 9 is arranged at the top of the protruding points 2, the load-bearing strength of the drainage plate is provided. The support structure includes a plurality of groups of protruding points 2 uniformly and spacedly arranged on the surface of the bottom plate 1. The top of the protruding points 2 is fixedly connected to the top plate 9, and a load-bearing structure is arranged on the surface of the top plate 9.

[0041] In another embodiment provided by the present invention, the 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 the clamping groove 5 opened inside the top plate 9, the assembly between multiple drainage plates is realized, and at the same time, the load-bearing strength of the drainage plate is improved. The load-bearing structure includes a cross-shaped and mutually separated slide rail 13 opened on the surface of the top plate 9. A sliding disk 12 is slidably connected inside the slide rail 13. The surface of the sliding disk 12 is connected to the load-bearing plate 3 through an elastic rod 11. There are four mutually independent groups of load-bearing plates 3. The bottom of the gap between the four groups of load-bearing plates 3 is slidably connected to a filling plate 4 through a limiting structure. The four groups of filling plates 4 are of an integral cross shape. The center position at the bottom 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 protruding point 2 through an elastic ring 8. The support rod 6 is slidably inserted into the inner side wall of the protruding point 2, and the top of the support rod 6 penetrates through the through hole 14 opened at the center position inside the top plate 9 to connect the filling plate 4. A clamping groove 5 is opened at the bottom inside the top plate 9, and clamping plates 18 for clamping and fixing both sides of the load-bearing plate 3 and the filling plate 4 are arranged inside the clamping groove 5.

[0042] 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 provide a limit to the movement track of the filling plate 4 between the gaps of the four groups of load-bearing plates 3. The limiting structure includes sliding grooves 17 opened in the middle positions on both sides of the load-bearing plate 3. A slider 16 is slidably connected in the sliding grooves 17, and the slider 16 is fixedly installed on the outer side of the filling plate 4.

[0043] In another embodiment provided by the present invention, cavities 10 are opened in both the bump 2 and the top plate 9. The cavity 10 in the bump 2 is a vertically penetrating type, and the cavity 10 in the top plate 9 is in a shape with an open bottom and a closed top. The vertically penetrating cavity 10 opened in the bump 2 communicates with the cavity 10 with an open bottom in the top plate 9. When assembling the drainage plate, the top plate 9 at the top end of the lower bump 2 can be directly inserted into the upper bump 2 and the top plate 9, and is fixedly assembled by inserting the load-bearing plate 3 and the filling plate 4 into the clamping grooves 5 opened on the inner side of the top plate 9.

[0044] In another embodiment provided by the present invention, the bottom parts on both sides of the load-bearing plate 3 are arranged in an inclined shape with the top end protruding outwards and the bottom end recessed inwards to adapt to the upward extrusion and sliding of the filling plate 4 between the gaps of multiple groups of load-bearing plates 3. By setting the bottom parts on both sides of the load-bearing plate 3 in an inclined shape, when the filling plate 4 slides upwards to fill the gap of the load-bearing plate 3, the filling plate 4 can slide upwards along the edge of the inclined load-bearing plate 3, which is convenient for the upward sliding of the filling plate 4.

[0045] In another embodiment provided by the present invention, the sliding grooves 17 opened on both sides of the load-bearing plate 3 are inclined. When the load-bearing plate 3 slides downwards and expands outwards at the same time, it is adapted to the movement track generated by the slider 16 when the filling plate 4 slides upwards. When the load-bearing plate 3 slides downwards, it will expand outwards, so as to slide the filling plate 4 upwards and insert it into the gap of the load-bearing plate 3. At this time, the movement track of the slider 16 is inclined on both sides of the load-bearing plate 3. Therefore, by setting the sliding grooves 17 in an inclined shape adapted to the track of the slider 16, it will not limit the upward sliding of the filling plate 4.

[0046] When the drainage plate is produced and sold, it generally needs to be wound up for storage and transportation. Therefore, when winding up, secondary limiting and fixing will be provided to the wound-up drainage plate:

[0047] The first fixing: When the bottom plate 1 drives the bump 2 to be wound up, the bump 2 is aligned with the cavity 10 inside the bump 2 provided on the bottom plate 1. At this time, when the rear bump 2 is inserted into the cavity 10 of the front bump 2, when inserted to a certain extent, the inner side wall of the cavity 10 will squeeze the load-bearing plate 3 due to its own size, and will expand the load-bearing plate 3 to a certain extent to cooperate with the extrusion of the inner side wall of the cavity 10 on the outer side of the load-bearing plate 3 to insert the bump 2 into the corresponding cavity for fixed limiting;

[0048] Second fixation: During the continuous winding of the drainage board, after the drainage board of the previous circle is inserted into the cavity 10 through the bump 2 for limit, when the drainage board of the next circle is wound, the drainage board of the next circle will squeeze the bottom ring 7, and squeeze the elastic ring 8 of the bottom ring 7, so that the filling plate 4 is pushed upward through the support rod 6 and inserted into the gap between multiple groups of load-bearing plates 3 that have been unfolded to a certain extent. And through the extrusion of the bottom ring 7 by the drainage board of the next circle, the load-bearing plate 3 that has been fixed for the first time can be further expanded outward in cooperation with the filling plate 4, so as to make the connection between the outer circle of the load-bearing plate 3 and the inner side wall of the cavity 10 more firm;

[0049] The wound drainage board is secondarily reinforced to fix the wound drainage board, so that only simple binding of the wound drainage board is required, which is convenient for winding and storing the drainage board. And compared with common drainage boards, it is more compact after winding, occupying less storage and transportation space;

[0050] After transporting the wound drainage board to the position where it is needed, unwind the drainage board, and the drainage board can be laid at the position where it is needed. When installing and combining multiple rolls of drainage boards, only need to place the previous group of drainage boards in place, and then insert the bumps 2 in the first row of the next group of drainage boards corresponding to the bumps 2 at the end of the previous group of drainage boards. The insertion of the bumps 2 here restricts the laying position of the next group of drainage boards, so that only the other end needs to be unwound and laid, and there is no need to adjust the laying position of the drainage board again;

[0051] After the laying is completed, use a rubber hammer to hammer down the bumps 2 at the connection position or directly step on them by the operator to fix the insertion between the two groups of bumps 2. When hammering down the upper bump 2, insert the lower bump 2 into the cavity 10 in the upper bump 2. During the hammering process, the bump 2 of the lower drainage board will be completely inserted into the upper bump 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 above, and at the same time the filling plate 4 is squeezed by the bottom ring 7 and the support rod 6, so that the load-bearing plate 3 expands outward under the restriction of the elastic rod 11 and the sliding disk 12 in the slide rail 13 and is inserted into the clamping groove 5. The two groups of clamping plates 18 arranged in the clamping groove 5 clamp and fix both sides of the load-bearing plate 3, so as to realize the fixation of the load-bearing plate 3 in the clamping groove 5. At the same time, the filling plate 4 will be restricted by the slider 16 and the chute 17 and fill the gap after the expansion of the load-bearing plate 3, so as to increase the contact area between the top of the bump 2 and the heavy object on the surface of the drainage board. Using the physical principle that when the contact area increases, the same force can generate a smaller pressure, the load-bearing capacity of the drainage board is increased;

[0052] Meanwhile, the elastic ring 8 with elastic deformation ability, which is connected to the bottom end of the bump 2 and the bottom ring 7, can provide a certain buffering ability between the bump 2 and the bottom ring 7, so as to provide a certain buffering force for the bump 2 during the load-bearing process and increase the load-bearing strength of the drainage board;

[0053] The expansion and contraction of the load-bearing plate 3 and the filling plate 4 can achieve various effects:

[0054] First: Install the drainage board by inserting between the bumps 2. Only the position of the first group of drainage boards needs to be adjusted during paving. For the subsequent drainage boards, they only need to be fixed between the bumps 2 and then can be laid on the support, without the need to adjust the position and then align and fix between the two groups of drainage boards;

[0055] Second: Insert between the bumps 2 of the drainage boards, so as to avoid a large gap without the support of the bumps 2 at the connection of the two groups of drainage boards. When laying the geotextile on the surface of the drainage board, the geotextile will not sink due to the lack of support of the bumps 2 at the connection of the drainage boards, which affects drainage use.

[0056] Third: By expanding the load-bearing plate 3 and the filling plate 4, the contact area during the load-bearing of the drainage board is increased, and the load-bearing capacity of the drainage board is increased;

[0057] Fourth: By expanding and inserting the load-bearing plate 3 and the filling plate 4 into the clamping groove 5 opened in the top plate 9, the fixed installation of multiple groups of drainage boards is realized and cannot be disassembled;

[0058] Fifth: Through the load-bearing plate 3 and the filling plate 4, during the winding, storage and transportation of the drainage board, the drainage board is fixed and tightened doubly, so as to wind the drainage board better;

[0059] The drainage board and the load-bearing plate 3 are mainly used to improve the load-bearing capacity of the drainage board, and at the same time, an additional unexpected effect is produced: it can provide a double reinforcement effect for the non-detachable assembly between the drainage boards.

[0060] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
