Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to a curb stone structure and a road dividing structure. Background Art

[0002] Municipal roads refer to urban roads. According to their position in the road network, traffic functions and service functions along the route, municipal roads are divided into five levels: expressways, trunk roads, secondary trunk roads, branch roads and district roads.

[0003] Curbstones and flat stones are installed in the central dividing strip, side dividing strip and sidewalk of the road. Curbstones and flat stones can play the role of edge finishing and dividing the functional strips of the road. At present, the existing designs of curbstones and flat stones are mainly in the form of rectangular blocks, and only the size may be different.

[0004] like Figure 1 As shown, a backrest 3 is provided between the sidewalk 2 and the motor vehicle lane 1, and a curb 5 and a flat stone 4 are provided on the backrest 3, which are perpendicular and abutted to each other. This design of curb 5 and flat stone 4 has the following three problems. First, there is a through seam at the joint of curb 5 and flat stone 4, and rainwater will seep into the pavement structure through the through seam; second, due to construction errors or post-construction settlement, the exposed height of the curb varies; third, some curbs 5 will tilt forward due to excessive fill pressure on the sidewalk.

[0005] In addition, if Figure 2 As shown, the prior art also provides a municipal road curb structure, which discloses the following contents:

[0006] 1) A drainage channel 106 is provided at the lower part of the front side of the curb stone; 2) Connecting protrusions 103 and connecting grooves are provided on the left and right sides of the curb stone respectively; 3) The connecting protrusions 103 and the connecting grooves 107 are located in the middle position above the longitudinal channel 104; 4) An arc portion 102 is provided on the upper front side and / or rear side of the curb stone body 101.

[0007] Although the above-mentioned curb stone structure can improve the existing rectangular curb stones and flat stones to a certain extent, it still has the following problems:

[0008] 1) The curbstone drainage channel 106 has a limited height and a small drainage capacity, and is only used in areas with low rainstorm intensity;

[0009] 2) After the curbstone is installed, the pavement compaction easily squeezes the pavement material into the drainage channel 106, causing blockage before use;

[0010] 3) The side connecting protrusions 103 and the connecting grooves 107 of the curb stone are mutually locked, so that the curb stones on the left and right sides are tightly connected, and the entire line of curb stones is connected as a whole. However, if some curb stones need to be replaced, they cannot be partially removed and spliced.

[0011] Therefore, it is necessary to propose a curbstone structure and a road dividing structure to solve at least one of the above problems. Utility Model Content

[0015] In a preferred embodiment, one of the left side surface and the right side surface is provided with a through-engaging portion and a limiting portion along the height direction, and the size of the engaging portion matches the size of the limiting portion.

[0016] In a preferred embodiment, the engaging portion includes a protrusion, and the limiting portion includes a groove, and the groove depth of the groove is consistent with the protrusion height of the protrusion.

[0017] In a preferred embodiment, the width of the groove is consistent with the width of the protrusion.

[0018] In a preferred embodiment, the width of the groove or the width of the protrusion is 1 / 4 of the width of the curb stone body.

[0019] In a preferred embodiment, the width of the groove is the same as the groove depth of the groove, and the protrusion height of the bump is the same as the width of the bump.

[0020] In a preferred embodiment, the depth dimension of the inwardly concave tongue and groove from the front side is the same as the height dimension of the outwardly convex tongue and groove from the rear side.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0068] The utility model provides a "Z"-shaped curb stone structure which can effectively ensure that the exposed height of the curb stone is flush, the curb stone connection is more firmly secured, and the curb stone structure is water-proof and forward-leaning.

[0069] Please refer to Figures 3 to 8 In the embodiment of the specification of the present application, a side stone structure is provided, which may include: a side stone body 500, wherein the side stone body 500 has a left side 501 and a right side 502 relative to each other along the length direction X, a front side 503 and a rear side 504 relative to each other along the width direction Y, and a top surface 505 and a bottom surface 506 relative to each other along the height direction Z, wherein the front side 503 is provided with an inner concave groove 510 for clamping with the flat stone 400; the inner concave groove 510 extends upward from the bottom surface 506 along the height direction Z to a first height dimension, and the first height dimension matches the height of the flat stone 400; the rear side 504 is provided with an outer convex groove 520 for clamping with the backrest 300, and the outer convex groove 520 extends upward from the bottom surface 506 along the height direction Z to a second height dimension, and the second height dimension matches the height of the clamping groove 310 of the backrest 300.

[0070] The curb stone structure provided in the implementation manner of the present application specification is a "Z"-shaped curb stone with an anti-water seepage function and a stable structure after installation.

[0071] In this embodiment, the side stone body 500 of the side stone structure can be in a rectangular parallelepiped shape as a whole, and has a left side 501 and a right side 502 opposite to each other, a front side 503 and a rear side 504 opposite to each other, and a top surface 505 and a bottom surface 506 opposite to each other. The front side 503 for matching with the peace stone 400 and the rear side 504 for matching with the backrest 300 are structurally improved. Figure 5As shown, the curb stone structure is overall in a "Z" shape.

[0072] For details, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The front side surface 503 is provided with an inner concave groove 510 for engaging with the flat stone 400; the inner concave groove 510 extends upward from the bottom surface 506 along the height direction Z to a first height dimension h1, and the first height dimension h1 matches the height of the flat stone 400, so as to ensure that the side stone structure and the flat stone 400 can be seamlessly connected when assembled. The rear side surface 504 is provided with an outer convex groove 520 for engaging with the backrest 300, and the outer convex groove 520 extends upward from the bottom surface 506 along the height direction Z to a second height dimension h2, and the second height dimension h2 matches the height of the slot 310 of the backrest 300, so as to ensure that the side stone structure and the backrest 300 can be seamlessly connected when assembled. The sum of the first height dimension and the second height dimension is equal to the height dimension of the side stone body 500. The first height dimension is the exposed height dimension of the curb stone structure, and the exposed height dimension can be determined according to the specification. Specifically, the exposed height can be 10 cm or 15 cm. After the exposed height dimension is determined, the second height dimension can be determined according to the actual size of the curb stone structure.

[0073] Specifically, the depth dimension of the concave groove 510 from the front side 503 is the same as the height dimension of the convex groove 520 from the rear side 504. For example, the depth dimension of the concave front side 503 can be b1, and the height dimension of the convex rear side 504 is also b1.

[0074] Specifically, the depth dimension or the height dimension is 1 / 3 of the width dimension of the curb body 500. When the depth dimension or the height dimension is 1 / 3 of the width of the curb body 500, the strength of the curb structure can be ensured, and the reliability of the curb structure when it cooperates with the flat stone 400 and the backrest 300 can also be ensured.

[0075] On the whole, in the embodiment of the present application, the side stone structure is exposed below the height h1, and is staggered and arranged in a "Z" shape, with the front side 503 partially concave b1 and the rear side 504 partially convex b1. The concave tongue and groove 510 of the front side 503 clamps the flat stone 400, which can ensure the height consistency of the side stone structure and prevent rainwater from seeping through the joints. The greater the soil pressure on the rear side 504, the tighter the squeezing, and the better the waterproof function. At the same time, when the side stone structure uses the concave tongue and groove 510 to resist the flat stone 400, it can prevent the side stone structure from tilting forward. The convex tongue and groove 520 of the rear side 504 can better connect the backrest 300, making the backrest 300 more secure, and can also play a role in balancing the soil pressure.

[0076] In some embodiments, the left side surface 501 and the right side surface 502 are provided with a through-engaging portion and a limiting portion in the height direction Z, and the size of the engaging portion matches the size of the limiting portion. For example, when the left side surface 501 is provided with a limiting portion and the right side surface 502 is provided with an engaging portion, the two can cooperate to form a locking structure, which can ensure the stability and reliability of the cooperation of two adjacent side stone structures on the one hand, and can easily replace a single side stone structure on the other hand.

[0077] Specifically, the engaging portion may include a protrusion 530 , and the limiting portion may include a groove 540 , and the groove depth of the groove 540 is consistent with the protrusion height of the protrusion 530 .

[0078] like Figure 8 As shown, when the engaging portion is a protrusion 530 and the limiting portion is a groove 540, the protrusion 530 of one curb structure can be engaged with the groove 540 of the other curb structure in the extension direction of the road, that is, in the length direction X, of two adjacent curb structures.

[0079] Of course, the specific configuration of the locking portion and the limiting portion may also be other methods and are not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0080] In the embodiment of the present application, the engaging portion is mainly illustrated in the form of a protrusion 530, and the limiting portion is mainly illustrated in the form of a groove 540. The width of the groove 540 is consistent with the width of the protrusion 530, so as to ensure that the two can be seamlessly connected when matched.

[0081] In one embodiment, the width of the groove 540 or the width of the protrusion 530 is 1 / 4 of the width of the side stone body 500. In the width direction Y, when the width of the groove 540 or the width of the protrusion 530 is 1 / 4 of the width of the side stone body 500, the reliability of the protrusion 530 and the groove 540 when they are matched can be ensured, and it is also convenient for processing and manufacturing.

[0082] Furthermore, the width of the groove 540 is the same as the groove depth of the groove 540, and the protrusion height of the protrusion 530 is the same as the width of the protrusion 530. In this way, it is more conducive to the standardized processing and manufacturing of the curb structure.

[0083] In the implementation mode of the present application, a "bump 530" and a "groove 540" are respectively provided on the left side 501 and the right side 502, which can increase the connection tightness between adjacent curbstone bodies 500 and improve the construction quality. In addition, since the solution provided by the present application is different from the existing invention in that the "bump 530" and the "groove 540" are continuous from top to bottom, when a curbstone structure is partially damaged, it can be taken out and assembled individually, so that it can be repaired and replaced at a lower cost.

[0084] like Figure 7 As shown, a road dividing structure is also provided in an embodiment of the present application, and the road dividing structure includes the above-mentioned curb stone structure, as well as a flat stone 400 and a backrest 300, and the backrest 300 is provided with a slot 310 that cooperates with the curb stone structure. The road dividing structure can achieve the technical effect achieved by the curb stone structure implementation embodiment by setting the curb stone structure. For details, please refer to the specific description of the above-mentioned implementation embodiment, and the present application will not repeat them here.

[0085] The road separation structure mainly includes a matching curbstone structure, a flat stone 400 and a backrest 300, which is used to separate the motor vehicle lane 100 and the sidewalk 200. One end of the flat stone 400 is used to abut against the motor vehicle lane 100, and the other end is matched with the curbstone structure; one side of the backrest 300 is matched with the curbstone structure, and the other side is used to abut against the sidewalk 200.

[0086] The specific size of the slot 310 of the backrest 300 can be matched with the size of the externally protruding groove 520, so as to ensure that when the curb structure and the backrest 300 are installed, the two can be seamlessly connected, thereby ensuring the reliability and stability of the connection.

[0087] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0088] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0089] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
