Description

Technical Field

[0001] The utility model relates to the field of drainage board support, in particular to a double-sided concave-convex drainage board support device. Background Art

[0002] Double-sided concave-convex drainage board is a kind of drainage board with convex cones on both sides. One convex cone does not have drainage holes, and the other convex cone has drainage holes. When the cone with drainage holes contacts the supporting surface (the supporting surface is soil at this time), rainwater can be drained into the soil. When the cone without drainage holes contacts the supporting surface, rainwater is discharged outward through the channels between the cones, avoiding direct discharge into the soil supporting surface.

[0003] In the prior art, the supporting surface is a non-soil hardened ground. After the drainage board is laid, heavy objects fall downward, causing the convex cone below to deform, which will cause the drainage channel to be blocked, thereby affecting the use effect of the drainage board.

[0006] The support mechanism comprises: a sleeve ring of an annular structure, a through hole is opened at the center of the sleeve ring, the cross section of the through hole is an "eight"-shaped structure that is wide at the top and narrow at the bottom, an inner wall of the through hole is circumferentially opened with a receiving groove, and an extrusion ring is clamped on the inner wall of the receiving groove;

[0007] An inner support seat is integrally formed on the bottom end of the sleeve ring, and an outer support seat is integrally formed on the outer circumference of the sleeve ring.

[0008] As a further solution of the present invention: the cross section between the outer support seat and the inner support seat is a triangular structure.

[0009] As a further solution of the utility model: the lower edge of the outer support seat is in a disc-shaped structure, and the bottom end of the outer support seat is flush with the bottom end of the inner support seat.

[0010] As a further solution of the utility model: the inner wall of the through hole is consistent with the outer walls of the upper convex vertebral body and the lower convex vertebral body.

[0011] As a further solution of the utility model: the outer diameter of the extrusion ring is larger than the inner diameter of the accommodating groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By setting up a supporting mechanism, the supporting mechanism can effectively reinforce and support the downward convex cone, disperse the impact force on the downward convex cone, and then form an effective supporting and protective effect, ensuring the use effect of the drainage board after laying.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 5In an embodiment of the utility model, a double-sided concave-convex drainage board supporting device comprises a connecting plate 1 and an upper convex cone 2 and a lower convex cone 3 distributed on the top and bottom of the connecting plate 1, and a supporting mechanism for supporting one of the upper convex cone 2 or the lower convex cone 3 is arranged below the connecting plate 1; the supporting mechanism comprises: a sleeve ring 4 in an annular structure, a through hole 7 is opened at the center of the sleeve ring 4, and the cross-section of the through hole 7 is an "eight"-shaped structure with a wide top and a narrow bottom, and an inner wall of the through hole 7 is circumferentially opened with a receiving groove 9, and an extrusion ring 8 is clamped on the inner wall of the receiving groove 9; an inner support seat 6 is integrally formed at the bottom end of the sleeve ring 4, and an outer support seat 5 is integrally formed on the outer circumference of the sleeve ring 4.

[0022] In this embodiment: before laying the drainage board, according to the laying requirements, one of the upper convex vertebral body 2 and the lower convex vertebral body 3 is turned downward, and then a supporting mechanism is set on the downward vertebral body;

[0023] Align the through hole 7 with the downward vertebral body, and then push the sleeve ring 4 to sleeve on the outer wall of the vertebral body. During the sleeve connection process, the extrusion ring 8 gradually enters the outer conical surface of the downward vertebral body and contacts it. After the contact, extrusion occurs. At this time, the extrusion ring 8 made of rubber material is deformed to increase the friction between the sleeve ring 4 and the downward vertebral body, so as to avoid the sleeve ring 4 from being separated from the downward vertebral body due to shaking or movement during the laying process after the sleeve connection is completed;

[0024] After paving is completed, the bottom end surface of the downward vertebral body and the outer support seat 5 and the inner support seat 6 are in contact with the paving surface. At this time, the inner support seat 6 and the outer support seat 5 form a stable support. The supporting force can prevent the downward vertebral body from being deformed when it is subjected to a large downward pressure, thereby avoiding the problem of poor drainage caused by the deformation of the vertebral body, thereby ensuring the quality of the drainage board.

[0025] Please refer to Figure 2 , Figure 4 and Figure 5 The cross section between the outer support seat 5 and the inner support seat 6 is a triangular structure.

[0026] In this embodiment, the triangular cross-sectional structure has good stability and avoids deformation between the outer support seat 5 and the inner support seat 6 .

[0027] Please refer to Figure 5 The lower edge of the outer support seat 5 is in a disc-shaped structure, and the bottom end of the outer support seat 5 is flush with the bottom end of the inner support seat 6.

[0028] In this embodiment, during laying, it can be ensured that the bottom ends of the outer support seat 5 and the inner support seat 6 are in contact with the support surface synchronously, thereby ensuring uniform force on the bottoms of the two.

[0029] Please refer to Figure 4 and Figure 5 The inner wall of the through hole 7 coincides with the outer wall of the upper convex vertebral body 2 and the lower convex vertebral body 3.

[0030] In this embodiment: after the downward convex vertebral body 2 or the downward convex vertebral body 3 is plugged into the through hole 7, the inner wall of the through hole 7 will not form a large extrusion pressure on the conical surface of the upper convex vertebral body 2 or the lower convex vertebral body 3, thereby avoiding the problem of surface deformation of the upper convex vertebral body 2 or the lower convex vertebral body 3 caused by the socket connection between the two, and the extrusion ring 8 is made of rubber material, which is relatively soft and will not cause surface deformation of the upper convex vertebral body 2 or the lower convex vertebral body 3.

[0031] Please refer to Figure 4 and Figure 5 , the outer diameter of the extrusion ring 8 is larger than the inner diameter of the accommodating groove 9.

[0032] In this embodiment: after the extrusion ring 8 is inserted into the receiving groove 9, the extrusion ring 8 is deformed, thereby increasing the connection force between the two and preventing the extrusion ring 8 from falling off.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
