Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a load-bearing polyurethane board for ground. Background Technology

[0002] Polyurethane board is a high-performance composite insulation material, usually composed of two metal panels (such as color steel plate, stainless steel plate, etc.) and an intermediate rigid polyurethane foam layer. With its excellent insulation, strength and durability, it has become one of the preferred materials in the fields of construction and cold chain.

[0003] Currently, rigid polyurethane foam layers have high compressive and shear strength, which can effectively withstand vertical and horizontal loads on the ground. Moreover, because polyurethane boards have a lower density than traditional materials (such as concrete and steel), they are lighter in weight. Therefore, polyurethane boards can reduce the pressure on the foundation when bearing loads on the ground, thus reducing the cost of foundation treatment.

[0004] Although rigid polyurethane foam has advantages such as lower density, lighter weight, and lower cost, its rigidity is weaker than that of metal. Therefore, its load-bearing capacity is still relatively weak when a heavy object is placed on it. Thus, reinforcing structures are often added inside the polyurethane board to improve its load-bearing capacity. However, if the load-bearing capacity is improved in this way, the polyurethane board is easily divided by the reinforcing structure, resulting in damage to its integrity and thus affecting its load-bearing capacity. Therefore, a ground load-bearing polyurethane board is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ground-load-bearing polyurethane board, which aims to improve the problem in the prior art where the reinforced structure is easily split in the polyurethane rigid foam layer, resulting in damage to its integrity and weakening of its load-bearing capacity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ground load-bearing polyurethane board, comprising a top plate and a bottom plate, wherein a rigid polyurethane foam board is disposed between the top plate and the bottom plate, and a load-bearing mechanism is also disposed between the top plate and the bottom plate;

[0007] The load-bearing mechanism includes a support plate, the upper surface of which is fixedly connected to the lower surface of the top plate, and the lower surface of which is fixedly connected to the upper surface of the bottom plate. A triangular groove is provided on the inner wall of the support plate, and a connecting strip is fixedly connected to one end of the support plate away from the middle of the top plate. A connecting component is provided on the outside of the connecting strip.

[0008] As a further description of the above technical solution:

[0009] The top plate and the bottom plate are both hexagonal in shape when viewed from above, and both are made of aluminum.

[0010] As a further description of the above technical solution:

[0011] The number of support plates is set to six, and the six support plates intersect at the geometric center corresponding to the top and bottom plate in the top view. The six support plates evenly divide the top and bottom plates into six equilateral triangular regions.

[0012] As a further description of the above technical solution:

[0013] The number of connecting strips is set to six, and the two ends of the six connecting strips are respectively fixedly connected to the side of the adjacent two support plates away from the middle of the top plate.

[0014] As a further description of the above technical solution:

[0015] The connecting component includes an outer protrusion and an inner concave block. The outer protrusion is fixedly connected to the side of the connecting strip away from the center of the top plate. The outer wall of the inner concave block is fixedly connected to the side of the connecting strip near the center of the top plate. The number of both the outer protrusion and the inner concave block is set to three. Each connecting strip has only one outer protrusion or one inner concave block on its exterior. The outer protrusion and the inner concave block are spaced apart. The inner wall of the inner concave block and the inner wall of the connecting strip are provided with a slot. The inner wall of the inner concave block outside the slot is provided with a limiting groove. The outer wall of the outer protrusion is fixedly connected with a limiting piece.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the outer protrusion and the inner wall of the connecting strip are provided with a connecting groove, and the outer wall of the polyurethane rigid foam board is provided with a protrusion extending into the inner side of the connecting groove.

[0018] As a further description of the above technical solution:

[0019] The support plate and connecting strip are made of aluminum alloy, as are the outer protrusion and inner concave block.

[0020] As a further description of the above technical solution:

[0021] The outer protrusion has an inclined chamfer on the side away from the connecting strip, and the width and height of the outer protrusion are consistent with the width and height of the slot.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting up a top plate, a bottom plate, a support plate, a triangular groove, a rigid polyurethane foam board, and a connecting strip, the support plate is set in its shape to ensure that the rigid polyurethane foam board can still be in an intact structure, and the support plate can maintain the stability of supporting the top plate through its remaining shape, thereby achieving the effect of protecting the integrity of the rigid polyurethane foam board and increasing the load-bearing capacity of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2This utility model provides an embodiment of a ground-bearing polyurethane board, including a top plate 1 and a bottom plate 2. The top plate 1 and the bottom plate 2 are both hexagonal in shape in their top view. Both the top plate 1 and the bottom plate 2 are made of aluminum. The aluminum plate enhances the overall load-bearing capacity of the polyurethane board, enabling it to better resist external pressure and deformation. A rigid polyurethane foam board 3 is provided between the top plate 1 and the bottom plate 2. The rigid polyurethane foam board 3 is made of high-density polyurethane material. The use of this material ensures that the equipment has lightweight, pressure and impact resistance, and flame retardant properties.

[0035] Reference Figures 2-4 A load-bearing mechanism 4 is also provided between the top plate 1 and the bottom plate 2. The load-bearing mechanism 4 includes support plates 41, and the number of support plates 41 is set to six. The six support plates 41 intersect at the geometric center corresponding to the top plate 1 and the bottom plate 2 in the top view. The six support plates 41 evenly divide the top plate 1 and the bottom plate 2 into six equilateral triangular regions. The upper surface of the support plate 41 is fixedly connected to the lower surface of the top plate 1, and the lower surface of the support plate 41 is fixedly connected to the upper surface of the bottom plate 2. The inner wall of the support plate 41 is provided with a triangular groove 42. Through the setting of the triangular groove 42, the polyurethane rigid foam board 3 is a complete whole and is not divided into six parts. The support plate 41 is arranged in a triangular shape, which makes the remaining part of the support plate 41 combine into multiple triangular aggregates, so as to give it stability and ensure the load-bearing capacity of the equipment. A connecting strip 43 is fixedly connected to the end of the support plate 41 away from the middle of the top plate 1. The number of connecting strips 43 is set to six, and the two ends of the six connecting strips 43 are respectively fixedly connected to the side of the two adjacent support plates 41 away from the middle of the top plate 1. By forming a triangle with the two adjacent support plates 41, the connecting strip 43 and the support plate 41 are combined to ensure stability and ensure the load-bearing capacity of the equipment. The support plate 41 and the connecting strip 43 are made of aluminum alloy.

[0036] Reference Figures 3-5A connecting component 44 is provided on the outside of the connecting strip 43. The connecting component 44 includes an outer protrusion 441 and an inner concave block 442. The outer protrusion 441 is fixedly connected to the side of the connecting strip 43 away from the middle of the top plate 1. The outer protrusion 441 is located on the outside of the space formed by the top plate 1 and the bottom plate 2. The outer wall of the inner concave block 442 is fixedly connected to the side of the connecting strip 43 near the middle of the top plate 1. The inner concave block 442 is located on the inside of the space formed by the top plate 1 and the bottom plate 2. The outer protrusion 441 and the inner concave block 442 are also made of aluminum alloy. The number of outer protrusion 441 and inner concave block 442 is set to three. Each connecting strip 43 has only one outer protrusion 441 or one inner concave block 442 on its outside. The connecting strips 442 are spaced apart, meaning that two adjacent connecting strips 43 are connected, one to the outer protrusion 441 and the other to the inner concave block 442. The inner wall of the inner concave block 442 and the inner wall of the connecting strip 43 are provided with a slot 443. The slot 443 is used to insert the outer protrusion 441 of another polyurethane board to achieve the insertion effect. The outer protrusion 441 is provided with an inclined chamfer on the side away from the connecting strip 43. The inclined chamfer makes it easier for the outer protrusion 441 to enter the slot 443. The width and height of the outer protrusion 441 are the same as the width and height of the slot 443. The inner wall of the inner concave block 442 outside the slot 443 is provided with a limiting groove 444. The width of the limiting groove 444 is wider than the width of the slot 443.

[0037] Reference Figure 3 , Figure 4 and Figure 6 The outer wall of the outer protrusion 441 is fixedly connected to a limiting piece 445. The limiting piece 445 is made of flexible material. When the outer wall of the limiting piece 445 encounters an obstacle, it can deform. The limiting piece 445 has shape memory, that is, when it is not subjected to force, it can restore its original shape. The inner wall of the outer protrusion 441 and the inner wall of the connecting strip 43 are provided with a connecting groove 446. The outer wall of the polyurethane rigid foam board 3 is provided with a protrusion extending into the inner side of the connecting groove 446. By setting the position of the protrusion of the polyurethane rigid foam board 3, it is ensured that the outer protrusion 441 will not be too heavy due to being solid, and at the same time, it will not have a poor insertion effect due to being hollow.

[0038] Working principle: When in use, since the support plate 41 has a triangular groove 42 inside, the polyurethane rigid foam board 3 between the top plate 1 and the bottom plate 2 can pass through the triangular groove 42 and be connected into a whole.

[0039] At the same time, when the top plate 1 is subjected to force, the top plate 1 can transfer the force to the upper surface of the support plate 41. Since the remaining shape of the support plate 41 forms multiple triangles, it has a certain stability. The support plate 41 can provide support force to the top plate 1, thereby increasing the load-bearing capacity of the entire polyurethane board.

[0040] At the same time, the two adjacent support plates 41 and the connecting strip 43 between them also form a triangle. Therefore, when the side of the equipment is subjected to force, it can also provide support through the triangle formed by the support plates 41 and the connecting strip 43, thereby enhancing the load-bearing capacity of the polyurethane board.

[0041] When multiple polyurethane boards need to be spliced ​​together, the worker inserts the outer protrusion 441 of one polyurethane board into the slot 443 of another polyurethane board. During this process, the limiting piece 445 deforms under force. When the outer protrusion 441 is fully inserted into the slot 443, the limiting piece 445 returns to its original shape and enters the interior of the limiting groove 444. Therefore, at this time, the outer protrusion 441 is relatively fixed to the slot 443 of the other polyurethane board.

[0042] Once fixed, since the outer protrusion 441 is entirely within the slot 443 of another polyurethane board, the area of ​​vertical overlap between the two adjacent polyurethane boards increases. Therefore, it is less likely for the two adjacent polyurethane boards to separate due to the weight of heavy objects, thus increasing the load-bearing capacity of the polyurethane board assembly after splicing.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
