Description

Technical Field

[0001] The utility model relates to the technical field of arc-shaped grass-planting bricks, in particular to an interlocking arc-shaped grass-planting brick. Background Art

[0002] In the prior art, a Chinese utility model patent with announcement number CN216663667U discloses an arc-shaped grass-planting brick, in which at least one of the two extended side walls of the circumferential side wall of the pressure strip adopts a curved surface shape. After being spliced ​​with other grass-planting bricks, the formed grass-planting road surface has a grass-planting space with a curved shape and a variable structure, which improves the ornamental value of the grass-planting road surface, thereby meeting the requirements for rich and colorful grass-planting and landscape parking spaces.

[0003] In the above-mentioned arc-shaped grass bricks, snap-in blocks are arranged on both sides of the pressure-bearing strip group to achieve an interlocking effect when the grass bricks are distributed and connected along the width direction. However, due to the arrangement of the snap-in blocks, the production materials of the arc-shaped grass bricks increase, thereby increasing the production cost. Moreover, since the snap-in blocks protrude from both sides of the pressure-bearing strip group, when stacking, the snap-in blocks between adjacent arc-shaped grass bricks cooperate with each other, occupying storage space, which is not easy to stack and store in large quantities, thereby being not conducive to transportation. In addition, when paved into a grass pavement, the snap-in blocks between adjacent arc-shaped grass bricks also occupy ground space, resulting in a reduction in the green grass planting area on the grass pavement. Moreover, after the above-mentioned arc-shaped grass bricks are paved to form a grass pavement, the grass holes are isolated from each other, which is not conducive to the uniform distribution of water flow on the grass pavement. Some grass holes have too much or too little water flow, thereby affecting the growth of green plants in each grass hole.

[0004] Therefore, it is necessary to improve the arc-shaped grass-planting bricks in the prior art. Utility Model Content

[0005] The utility model aims to overcome the defects in the prior art and provide an interlocking arc-shaped grass-planting brick which reduces production materials to reduce costs, is convenient for splicing and stacking and transportation, and is conducive to uniform distribution of water flow to ensure the growth of green plants.

[0006] In order to achieve the above technical effects, the technical solution of the utility model is: an interlocking arc-shaped grass-planting brick, comprising an arc-shaped brick body, wherein the arc-shaped brick body comprises:

[0007] A pressure bearing group, the pressure bearing group comprises at least three pressure bearing strips which are evenly spaced and arranged side by side along the width direction of the arc-shaped brick body, the circumferential side wall of the pressure bearing strip comprises two curved side walls which are distributed along the distribution direction of the pressure bearing strip, and the two curved side walls are curved surfaces extending along the length direction of the pressure bearing strip;

[0008] A connection group, wherein the connection group is arranged between two adjacent pressure bars, and the connection group and the two adjacent pressure bars enclose two back-to-back splicing grooves and a grass-planting hole arranged between the two splicing grooves, and the notches of each splicing groove are adapted to the ends of the pressure bars;

[0009] The circumferential outer edge of the arc-shaped brick body comprises two opposite and parallel outer side walls, and two opposite curved side walls in the pressure strip at the end positions are respectively arranged on the two outer side walls.

[0010] Preferably, in order to ensure the pressure-bearing area and avoid the pressure-bearing strips having too large a spacing therebetween, which would affect pedestrians' walking, the width of the pressure-bearing strip is greater than the spacing therebetween.

[0011] Preferably, in order to facilitate the splicing between the arc-shaped grass-planting bricks, both ends of the pressure strip are provided with assembly protrusions, and the assembly protrusions are matched with the notches of the splicing grooves.

[0012] Preferably, in order to facilitate the insertion of the assembly protrusion into the splicing groove, the end of the assembly protrusion is provided with a chamfer.

[0013] Preferably, in order to further facilitate the mutual splicing between the arc-shaped grass bricks, the circumferential side wall of the pressure strip also includes a straight side wall integrally connected to the end of the curved side wall, and the straight side wall extends along the length direction of the arc-shaped brick body and is connected to the notch of the splicing groove.

[0014] Preferably, in order to reserve some space in the splicing groove for the growth of green plants when the arc-shaped grass-planting bricks are spliced, the depth of the splicing groove is greater than the length dimension of the assembly protrusion along the extension direction of the pressure strip.

[0015] Preferably, in order to achieve connection between the pressure bars, the connection group includes a connection block fixed between two adjacent pressure bars, the connection blocks are distributed along a direction parallel to the length of the pressure bars, and two adjacent pressure bars and two adjacent connection blocks enclose the grass planting hole.

[0017] Preferably, in order to ensure that the grass planting holes are interconnected after the arc-shaped grass planting bricks are spliced, the guide groove includes a transverse groove, which extends in a distribution direction parallel to the pressure strips and has two ends extending to the circumferential outer edge of the arc-shaped brick body.

[0018] Preferably, in order to further ensure the interconnection between adjacent arc-shaped grass bricks after splicing, the guide groove also includes a longitudinal groove, which extends in a length direction parallel to the pressure strip and has two ends extending to the bottoms of two splicing grooves arranged back to back.

[0019] To sum up, compared with the prior art, the interlocking arc grass brick of the utility model utilizes the end of the pressure strip to fit with the notch of the splicing groove, which facilitates the splicing between the arc brick bodies and achieves interlocking while ensuring that the two outer walls of the arc brick body are parallel, which not only saves production materials and reduces production costs, but also facilitates stacking and transportation.

DETAILED DESCRIPTION

[0029] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0030] like Figure 1-Figure 4As shown, the interlocking curved grass-planting brick of the utility model comprises a curved brick body, and the curved brick body comprises:

[0031] A pressure bearing group, the pressure bearing group comprises at least three pressure bearing strips 1 which are evenly spaced and arranged side by side along the width direction of the arc-shaped brick body, the circumferential side wall of the pressure bearing strip 1 comprises two curved side walls 11 which are distributed along the distribution direction of the pressure bearing strip 1, and the two curved side walls 11 are curved surfaces extending along the length direction of the pressure bearing strip 1;

[0032] A connection group 2, the connection group 2 is arranged between two adjacent pressure strips 1, the connection group 2 and the two adjacent pressure strips 1 enclose two back-to-back splicing grooves 3 and a grass-planting hole 4 arranged between the two splicing grooves 3, and the notches of each splicing groove 3 are adapted to the ends of the pressure strips 1;

[0033] The circumferential outer edge of the arc-shaped brick body includes two opposite and parallel outer side walls, and the two opposite curved side walls 11 in the pressure strip 1 at the end position are respectively arranged on the two outer side walls.

[0034] The interlocking arc-shaped grass brick in the utility model has an arc-shaped overall structural dimension. The arc-shaped brick body includes four equally spaced pressure strips 1, and the four pressure strips 1 form three gaps (of course, according to other production needs, the pressure strips 1 can also be three or other multiple numbers to ensure that at least two gaps are formed between the pressure strips 1 in the pressure group). In the circumferential side walls of the pressure strips 1, two side walls extending along their own length direction and relatively parallel both include curved side walls 11, and the curved side walls 11 are curved. Specifically, when the grass brick body is placed horizontally, the projection of the curved side walls 11 on the horizontal plane is an arc structure composed of two arc segments connected by a smooth transition, so as to meet the aesthetic requirements of the curved grass pavement formed when the arc-shaped grass brick is laid on the pavement.

[0035] There are three connection groups 2, which are spaced apart from the four pressure bars 1. The connection groups 2 include a connection block 21 fixed between two adjacent pressure bars 1. The connection blocks 21 are distributed along a direction parallel to the length of the pressure bars 1. Two adjacent pressure bars 1 and two adjacent connection blocks 21 enclose a grass planting hole 4.

[0036] To be more specific, the connection group 2 includes three connection blocks 21, and the three connection blocks 21 are evenly spaced along the length direction of the pressure bar 1. There is a gap between the connection group 2 and the end of the pressure bar 1. After adopting the above structure, two adjacent pressure bars 1 and the three connection blocks 21 in the connection group 2 located between the two pressure bars 1 can enclose two grass planting holes 4 and two splicing grooves 3. The two splicing grooves 3 are arranged back to back, and the groove openings are located at the end positions of the grass planting brick body. The two grass planting holes 4 are located between the two splicing grooves 3.

[0037] When the arc-shaped grass-planting brick is laid, the two grass-planting holes 4 are used to plant green grass. Since the notch of the splicing groove 3 is adapted to the end of the pressure strip 1, it is convenient to use the following method when laying the arc-shaped grass-planting brick: Figure 5-Figure 7 The staggered paving method shown, specifically, is to fit part of the end of the pressure strip 1 of one of the arc-shaped brick bodies to the notch of the splicing groove 3 of the other arc-shaped brick body, and along the length direction of the arc-shaped brick body, the adjacent ends of the two arc-shaped brick bodies fit together, so that part of the splicing groove 3 and the end of the pressure strip 1 are exposed at the adjacent ends of the two arc-shaped brick bodies, which is convenient for connection with other arc-shaped brick bodies. In this way, an interlocking connection is achieved, which ensures the structural stability of the grass-planting road surface paved with the arc-shaped grass-planting bricks and avoids positional displacement of the arc-shaped bricks.

[0038] On the basis of ensuring the stability of the pavement structure by interlocking, there is no need to set interlocking clamping blocks on the side walls of the curved brick body. This saves production materials, reduces production costs, and reduces the weight of the curved grass bricks, making transportation and handling easier.

[0039] Moreover, in the arc-shaped grass-planting brick of the utility model, the two outer side walls of the arc-shaped brick body are opposite to each other and parallel, and in the two pressure-bearing strips 1 at the end positions in the pressure-bearing group, the two opposite curved side walls 11 are arranged on the above-mentioned two outer side walls, so that when the arc-shaped grass-planting brick is stacked and arranged, it can be arranged as follows: Figure 8 In the manner shown, in the width direction of the arc-shaped brick body, the two outer side walls of two adjacent arc-shaped brick bodies fit together, and in the length direction of the arc-shaped brick body, the ends of two adjacent arc-shaped brick bodies abut against each other. Since the arc-shaped brick body is not provided with a snap-in block on the side, the space for stacking and arranging is saved, which is convenient for storage and transportation.

[0040] In addition, the arc-shaped grass-planting bricks of the utility model are used to form Figure 5-Figure 7 After the grass-planted pavement is shown, along the width direction of the arc-shaped grass-planting bricks, the gap between the two outer walls facing adjacent arc-shaped bricks forms a grass-planting opening 6 extending along the length direction of the pressure strip 1. Since there are no snap-fit ​​blocks on the outer walls, the green planting area can be increased.

[0041] A further improvement is that the width of the pressure strip 1 is greater than the spacing between the pressure strips 1 ; both ends of the pressure strip 1 are provided with assembly protrusions 12 , and the assembly protrusions 12 are matched with the notches of the splicing grooves 3 .

[0042] After adopting the above design, the width of the pressure strip 1 is guaranteed, thereby ensuring the structural strength of the pressure strip 1, and avoiding the pressure strip 1 being too narrow, which causes discomfort to pedestrians when walking on the road surface paved with the arc-shaped grass bricks due to too small foot contact area, and facilitates pedestrians to walk safely on the grass-planted road surface. By matching the assembly protrusion 12 with the notch of the splicing groove 3, the assembly protrusion 12 is conveniently inserted into the notch of the splicing groove 3, thereby realizing the interlocking connection between the arc-shaped grass bricks.

[0043] A further improvement is that the end of the assembly protrusion 12 is provided with a chamfer 121. By providing the chamfer 121, the end size of the assembly protrusion 12 is reduced, and the assembly protrusion 12 is conveniently inserted into the splicing groove 3 to achieve the interlocking connection of the arc-shaped grass-planting bricks.

[0044] A further improvement is that the circumferential side wall of the pressure strip 1 further includes a straight side wall 13 integrally connected to the end of the curved side wall 11, the straight side wall 13 extending along the length direction of the arc-shaped brick body and connected to the notch of the splicing groove 3. When the arc-shaped grass-planting brick is placed horizontally, the projection of the straight side wall 13 on the horizontal plane is a straight line segment extending along the length direction of the arc-shaped brick body, and the straight side wall 13 is arranged at the end position of the pressure strip 1. With this design, it is convenient for the arc-shaped grass-planting bricks to be spliced ​​with each other in their own length direction.

[0045] A further improvement is that the groove depth of the splicing groove 3 is greater than the length dimension of the assembly protrusion 12 along the extension direction of the pressure strip 1. Specifically, the protrusion depth of the assembly protrusion 12 is much smaller than the groove depth of the splicing groove 3. In this way, when two arc-shaped grass-planting bricks are spliced ​​along the length direction of the two, after the assembly protrusion 12 is inserted into the splicing groove 3, there is a longer distance between the end of the assembly protrusion 12 and the groove bottom of the splicing groove 3. The assembly protrusion 12 only occupies a small part of the splicing groove 3, so that most of the space of the splicing groove 3 can be left, which is convenient for planting green grass in the remaining space of the splicing groove 3, thereby increasing the greening area of ​​the grass-planting road surface and improving the road surface environment.

[0046] A further improvement is that a guide groove 5 is provided on the bottom surface of the arc-shaped brick body, and the grass planting hole 4 and the splicing groove 3 are interconnected through the guide groove 5; the guide groove 5 includes a transverse groove 51, which extends along a distribution direction parallel to the pressure strip 1, and both ends extend to the circumferential outer edge of the arc-shaped brick body; the guide groove 5 also includes a longitudinal groove 52, which extends along a length direction parallel to the pressure strip 1, and both ends extend to the bottom of two splicing grooves 3 arranged back to back.

[0047] Specifically, the guide groove 5 includes three transverse grooves 51 and three longitudinal grooves 52. The transverse grooves 51 and the longitudinal grooves 52 are through grooves, and the ends extend to the outer wall of the arc-shaped brick body. Through the transverse grooves 51 and the longitudinal grooves 52, the water flow at the bottom of the grass-planting road surface is convenient to circulate between the grass-planting holes 4, the splicing grooves 3 and the grass-planting openings 6. In this way, the water flow is evenly distributed at the bottom of the grass-planting road surface, avoiding the isolation of the grass-planting holes 4, the splicing grooves 3 and the grass-planting openings 6 from each other, resulting in excessive or insufficient water flow in some positions. In this way, the transverse grooves 51 and the longitudinal grooves 52 are used to guide the water flow to be evenly distributed, which is beneficial to the growth of green plants in the grass-planting holes 4, the splicing grooves 3 and the grass-planting openings 6, and improves the survival rate. In addition, the design of the guide groove 5 at the bottom of the arc-shaped brick body can also reduce the amount of production materials used in the production of the arc-planting bricks of the utility model to a certain extent, thereby reducing the production cost, while reducing its own weight, facilitating transportation and handling, and reducing the work intensity of workers during laying.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
