Description

Technical Field

[0001] This invention relates to a block and retaining wall system. Background Technology

[0002] If slopes of mountains, roads, and water bodies are not protected, they are prone to collapse, landslides, and soil erosion.

[0003] Traditional slope protection methods often involve masonry, concrete retaining walls, and blocks. Currently, there are many ecological retaining wall and slope protection brick products on the market. Their common features are that they are dry-laid and stacked without the need for mortar fixation, making construction simple. Some bricks even have plant growth holes, resulting in good ecological landscape effects.

[0004] Typical examples of blocks include the interlocking brickwork disclosed in Chinese patent document CN211312554U, the spatially interlocking ecological blocks disclosed in Chinese patent document CN104514227B, the interlocking ecological block retaining wall system disclosed in Chinese patent document CN 109594583 B, and the large-pore self-locking infiltration and vegetated blocks disclosed in Chinese patent document CN204715297U.

[0005] The aforementioned blocks are stacked at varying heights to form structural interlocks, for example, as shown in the image. Figure 24 The blocking method shown (see document CN211312554U) and as follows Figure 25 The locking method shown (see document CN204715297U) was found by the inventors during the implementation of the present invention to directly result in the blocks in the slope protection / retaining wall being placed in a messy and disorderly manner, and the stacked retaining wall could not achieve neatness and order, which greatly limited its application scenarios and affected its promotion and use. Summary of the Invention

[0006] The purpose of this invention is to provide a block that allows for the construction of a neat and orderly retaining wall.

[0007] Another objective of this invention is to provide a retaining wall system composed of the aforementioned blocks.

[0008] To address this, the present invention provides a block comprising a body, wherein a first toothed block and a second toothed block are provided on the left and right sides of the body, the first toothed block being close to the front wall of the body, and a first groove being formed between the first toothed block and the second toothed block on the same side of the body, wherein the first groove can accommodate the first toothed block or the second toothed block of another block when the blocks are stacked, characterized in that it further comprises a first shaping block extending outward from the lower half of the front wall of the body, so as to form an aligned step between the upper half of the front wall of the left and right adjacent blocks when the retaining wall is stacked.

[0009] According to another aspect of the present invention, a retaining wall system is provided, which is constructed of blocks and half-layer blocks, wherein the blocks are blocks as described above, wherein at the bottom layer of the retaining wall, the blocks and the upper half-layer blocks are arranged alternately, and the first tooth of the block is locked / blocked with the first groove of the laterally adjacent upper half-layer block, the front wall of the upper half-layer block forms a step with the first shaping block of the block, at any intermediate layer of the retaining wall, the first tooth of the block is locked / blocked with the first groove of the laterally adjacent block, the first shaping block of the block forms a step with the upper half front wall of the left and right adjacent blocks, and at the top layer of the retaining wall, the lower half-layer blocks / the upper half-layer blocks placed in the opposite direction are locked / blocked with the laterally adjacent blocks.

[0010] The present invention also provides a block comprising a body, wherein a first toothed block and a second toothed block are provided on the left and right sides of the body, the first toothed block being close to the front wall, and a first groove being formed between the first toothed block and the second toothed block on the same side of the body. When the blocks are stacked, the first groove can accommodate the first toothed block or the second toothed block of another block. The first toothed block is a modified toothed block, comprising a first part and a second part. The first part abuts or locks with the first groove of another block, and the tooth shape of the second part is modified / shaped.

[0011] The present invention also provides a block comprising a body, wherein a first toothed block and a second toothed block are provided on the left and right sides of the body, the first toothed block being close to the front wall of the body, and a first groove being formed between the first toothed block and the second toothed block on the same side of the body, wherein the first groove can accommodate the first toothed block or the second toothed block of another block when the blocks are stacked, wherein the front wall of the body is a deformed front wall and / or the first toothed block is a deformed toothed block, so that the retaining wall stacked by the blocks is neat and orderly.

[0012] This invention, through a first variation of the front wall of the block body (adding a shaping block), uses the front wall surface of the shaping block as a reference to align and stack the blocks, which can form straight steps or irregular steps (also known as fancy steps), thus organically combining the blocking and locking function with a neat and orderly shape, overcoming the problem that existing blocks cannot achieve a neat and orderly shape when building retaining walls.

[0013] By modifying the first tooth block, this invention removes the additional constraints that the complete tooth block imposes on the shape of the retaining wall while ensuring the original function of the retaining lock, thus allowing for a more flexible and diverse design of the retaining wall.

[0014] The present invention achieves a second variation of the front wall of the block body (forming a beveled surface), which can form a flat slope or a coplanar surface on the front wall surface, thus organically combining the neat and orderly shape and the retaining function, overcoming the problem that existing blocks cannot achieve a neat and orderly shape when building retaining walls.

[0015] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0041] Example 1

[0042] like Figure 1 As shown, the block in this embodiment includes a body 10, which is a three-dimensional structure stretched along the normal direction from a left-right symmetrical geometric shape; a first toothed block 12 and a second toothed block 13 are provided on the left and right sides of the body 10; the body 10 is a hollow body with a large through hole 10a running vertically through it. In other embodiments, the large through hole 10a can be divided into several small through holes, or the body 10 can also be a solid body.

[0043] A groove 14 is formed between the first tooth block 12 and the second tooth block 13 on the same side of the main body 10; the groove 14 can accommodate the first tooth block 12 or the second tooth block 13 of other blocks.

[0044] The first toothed block 12 is located on both sides of the front wall 11 of the main body and is integrated with the front wall of the main body. The main body has a front wall surface 15 and a top surface 16. The second toothed block 13 is offset from the rear wall surface by a certain distance. When stacking, the front wall surface 15 faces outward, and the back side opposite to the front wall surface faces the slope protection foundation and is not visible.

[0045] This block also includes a shaping block 17 extending from the lower half of the front wall surface. The shaping block 17 is rectangular, with the same width and bottom as the main body, and its height is half the height of the main body. When laying the blocks, the shaping block 17 can fill the gap between the front walls of the adjacent blocks on the left and right sides, so that the shaping block is aligned and transitioned with the front wall surface (upper half) of the adjacent blocks on the left and right sides, and the top surface is aligned and transitioned.

[0046] When stacking, the blocks are stacked as follows: with the front wall facing outwards, the blocks are stacked one block back, with upper and lower layers of blocks staggered in the height direction, and aligned with the front wall surface of the shaping block 17 as a reference. Specifically, the lower half of the first toothed block 12 is interlocked with the groove of the block below it, and the upper half of the second toothed block 13 is interlocked with the groove of the block above it.

[0047] like Figure 2 As shown, in a retaining wall system constructed from masonry blocks, the same block can form two continuously extending straight steps (two steps). One straight step is formed by the exposed front wall 11 of the block and the shaping blocks 17 of the adjacent blocks on the left and right. The other straight step is formed by the shaping blocks 17 of the block and the front wall 11 (upper part) of the adjacent blocks on the left and right.

[0048] This invention overcomes the problems of messy overall block placement, non-coplanar adjacent blocks, and inability to form straight steps by setting up a shaping block that combines with the existing block structure, while maintaining the locking function.

[0049] In this embodiment, "accommodation" refers to the interlocking insertion between the groove and the toothed block. In other embodiments, "accommodation" can also refer to a resisting fit, such as... Figure 24 As shown, one side of the groove abuts against the toothed block.

[0050] Example 2

[0051] like Figure 3 and Figure 4 As shown, the block in this embodiment differs from that in Embodiment 1 in that a notch 18 is provided on the outer surface of the shaped block 17. This notch 18 communicates with the through hole in the body of the lower block for purposes such as planting grass.

[0052] Example 3

[0053] In the blocks of this embodiment, such as Figure 5 and Figure 6As shown, the first tooth block 12 and the second tooth block 13 have different cross sections from those in Embodiment 1. The cross sections of the first tooth block 12 and the second tooth block 13 in this embodiment are trapezoidal (or dovetail-shaped). The upper half of the first tooth block 12 is modified, and the upper half of the front wall surface forms a flat surface. The lower half of the tooth shape is completely preserved, and a part of it protrudes from the front wall surface 15.

[0054] In this embodiment, the first toothed block protruding from the front wall does not affect the alignment transition between the shaping block and the adjacent block, and maintains the complete plug-in interlocking structure.

[0055] The present invention modifies the upper half of the first tooth block so that the front wall and the modified block form a continuously extending straight step.

[0056] Example 4

[0057] like Figure 7 and Figure 8 As shown, unlike the rectangular cross-section toothed block in Embodiment 1, the first toothed block 12 and the second toothed block 13 in this embodiment have trapezoidal cross-sections. The upper half of the front wall of the brick is a flat plane. The toothed block 12 is a modified toothed block relative to the toothed block 13. The lower half 12a of the toothed block 12 is a complete tooth shape, and the upper half 12b is the tooth tip portion cut off from 1 / 2 tooth height.

[0058] The total width of the front wall of the main body is the width of the main body plus one tooth height, and the shaping block 17 is the same width as the front wall. In this embodiment, the brick joints between the shaping blocks and the front wall surface are arranged at equal intervals on the same step.

[0059] Example 5

[0060] like Figure 9 and Figure 10 As shown, the cross-section of the tooth block 12 in this embodiment is rectangular, and the front wall surface of the body is a double cylindrical surface. The tooth block 12 is a modified tooth block relative to the tooth block 13. The lower half 12a of the tooth block 12 is a complete tooth shape, and the upper half 12b is the tooth tip portion removed from 1 / 2 tooth height.

[0061] The total width of the front wall of the main body is the width of the main body plus 1 tooth height, and the width of the shaping block is the same as that of the front wall surface.

[0062] The front wall surface is a double cylindrical surface 15a, and the forearm surface 17a of the modified block is also a double cylindrical surface; the two have the same shape.

[0063] When building, such as Figure 10 As shown, the building blocks are laid in the same way as the blocks in Example 1.

[0064] The same block forms two steps. One step is formed by the exposed front wall and the shaped block of the adjacent block, and the other step is formed by the shaped block and the front wall of the adjacent block.

[0065] In this embodiment, the modified blocks are arranged with the same width as the front wall surface. The double cylindrical surfaces of the modified blocks are aligned and transitioned with the double cylindrical front wall surfaces of the adjacent blocks to form a cylindrical surface array step.

[0066] Unlike the straight steps in Embodiment 1, the steps formed in this embodiment are irregularly shaped steps, or fancy steps, which make the steps of the retaining wall break through the straight shape.

[0067] Example 6

[0068] like Figure 11 and Figure 12 As shown, in this embodiment, the total width of the front wall of the body is the width of the body plus one tooth height, and the width of the shaping block is the same as that of the front wall surface. The front wall surface 11a of the upper half of the front wall of the body is a convex surface, and the forearm surface 17a of the shaping block 17 is a concave surface, which is the reverse curved surface of the convex surface.

[0069] When building, such as Figure 12 As shown, the building blocks are laid in the same way as the blocks in Example 1.

[0070] The same block forms two steps. One step is formed by the exposed front wall and the shaped block of the adjacent block, and the other step is formed by the shaped block and the front wall of the adjacent block.

[0071] In this embodiment, the shaping blocks are arranged with the same width as the front wall surface. The concave surface of the shaping block is aligned with the convex surface of the adjacent block to form an overall wavy stepped surface with alternating convex and concave sections.

[0072] Example 7

[0073] like Figure 13 and Figure 14 As shown, in this embodiment, the block body 10 also includes a shaping block 17' and a shaping block 17" extending from the front wall of the block body, the height of which is 1 / 2 of the height of the block body. When stacking, the shaping blocks 17' and 17" are used to fill part of the gap between the left and right adjacent blocks, so that the left and right sides of the front wall of the block are aligned with the shaping blocks and the top plane is aligned with the shaping blocks.

[0074] Unlike the flat surface of the front wall in Embodiment 1, in this embodiment, the total width of the front wall of the body is the width of the body plus 1 tooth height, and the shaping block is the same width as the front wall.

[0075] The front wall surface 11a is an arc surface, and the outer wall surfaces 17a / 17b of the shaping block are extension surfaces with the same curvature as the arc surface, thus forming a cross-arc step.

[0076] When building, such as Figure 14As shown, this block is stacked in the same way as existing blocks, with adjacent blocks interlocked by toothed blocks and staggered in the height direction.

[0077] The same block forms two steps. One step is composed of the exposed front wall and the shaped block of the adjacent block, and the other step is composed of the shaped block and the front wall of the adjacent block.

[0078] In this embodiment, the front wall surface and the two left and right shaping blocks form a cross-arc step, and the cross-arc steps of the same height are arranged at equal intervals. The upper and lower cross-arc steps are stacked in a fish-scale pattern.

[0079] In this embodiment, the shape of the step is formed by the front wall and two modified blocks of the same type on its left and right. The width of the arc surface exceeds the block itself, hence it is called a cross-arc shape.

[0080] Example 8

[0081] like Figure 15 As shown, the retaining wall system in this embodiment is composed of blocks 1 and half-layer blocks. Here, a half-layer block refers to a block composed of the upper half of the entire block (i.e., upper half-layer block 2) or a block composed of the lower half of the entire block (i.e., lower half-layer block 3).

[0082] At the bottom layer of the retaining wall, blocks 1 and upper half-layer blocks 2 are arranged alternately, and the first toothed block of block 1 and the first groove of the horizontally adjacent upper half-layer block 2 are locked / blocked. The front wall of the upper half-layer block 2 forms a step with the shaping block of the adjacent block 1. In any intermediate layer of the retaining wall, the first toothed block of block 1 is locked / blocked with the first groove of the horizontally adjacent block 1', and the upper half of the front wall of block 1 forms a step with the shaping blocks of the left and right adjacent blocks 1'. At the top layer of the retaining wall, the lower half-layer blocks 3 / the upper half-layer blocks 2 placed in the opposite direction are locked / blocked with the horizontally adjacent blocks 1.

[0083] When the upper half-layer block 2 of this embodiment is placed in the opposite direction, the front and rear walls of two adjacent blocks can be flush.

[0084] In this embodiment, the upper half of the block can be used alone, or the upper and lower half of the block can be used simultaneously.

[0085] Thus, the surface of the retaining wall system in this embodiment forms steps, with the top and bottom flattened, making the retaining wall surface neat and orderly, overcoming the problem of messy placement. Through the shaping of the modified blocks, the present invention makes the constructed retaining wall / slope appear from the outside as a conventional rectangular block structure, without revealing the ingenious internal structure, thus concealing the ingenuity in simplicity.

[0086] Example 9

[0087] like Figure 16 and Figure 17 As shown, in this embodiment, the basic shape of the block is... Figure 25 The block shown differs from Embodiment 1 in that, in addition to the first toothed block 12 and the second gear 13, the block body also includes a third toothed block 19 on both sides.

[0088] In this embodiment, the block has a shaping block 17 on the front wall of the main body. The bottom layer of the retaining wall uses complete block 1 and upper half block 2, which are aligned and stacked with the front wall surface of the shaping block 17 as a reference to form an aligned step.

[0089] Example 10

[0090] like Figure 18 and Figure 19 As shown, the block in this embodiment includes a body 10, with a first toothed block 12 and a second toothed block 13 on the left and right sides of the body. A first groove 14 is formed between the first toothed block 12 and the second toothed block 13 on the same side of the body. When the blocks are stacked, the first groove can accommodate the first toothed block or the second toothed block of another block.

[0091] The first toothed block 12 is a modified toothed block. The first toothed block includes a first part 12a with complete tooth shape and a second part 12b with incomplete tooth shape. The first part 12a blocks or locks with the first groove of another block during stacking. The tooth shape of the second part 12b is completely or partially cut off.

[0092] In this embodiment, the second part of the first toothed block is arc-shaped after part of the solid is removed, that is, the two sides of the front wall surface 15 of the main body transition to the front wall surface of another block through an arc. The retaining wall system formed by this block can reduce the impact damage of water flow on the block when used underwater.

[0093] All of the above embodiments three to seven used modified toothed blocks, which play an important role in shaping the retaining wall system.

[0094] Example 11

[0095] like Figure 20 and Figure 21 As shown, the difference from Embodiment 10 is that the toothed block cross-section of the block body is rectangular.

[0096] The front wall of the main body and the tooth block are fused together. Half of the tooth height of the tooth block is fused with the front wall. The first tooth block is a modified tooth block, with its upper half removed and the lower half 12a retained.

[0097] The front wall 11 of the block body is changed from a straight wall surface to a beveled surface. In this way, when the same type of blocks are stacked to build a retaining wall, multiple beveled surfaces are on the same plane, and then spliced ​​together to form a flat slope. At this time, the front wall surface of each block is the same size, but they are staggered in height.

[0098] This block design is suitable for brick pressing.

[0099] This invention, through the deformation of the front wall of the block body, can form a flat slope, thus organically combining the neat and orderly shape with the retaining function, overcoming the problem that existing blocks cannot achieve a neat and orderly shape when building retaining walls.

[0100] Example 12

[0101] like Figure 22 and Figure 23 As shown, the difference from Embodiment 10 is that the cross-section of the toothed block of the block body is rectangular. The front wall of the body and the toothed block are fused together, wherein 1 / 2 of the tooth height of the toothed block is fused with the front wall, and the first toothed block is a modified toothed block, the upper half of which is cut off, and the lower half 12a is retained.

[0102] The front wall of the block body has an outward-extending portal frame 21. The outer wall surface 21a of the portal frame is a beveled surface. The beveled surface is coplanar when the same type of blocks are stacked to form a retaining wall, and is located on the same slope. The portal frame 21 exposes the passage 10a to form functions such as planting grass and stepping. The outer wall surface of each block is of equal size and staggered in height.

[0103] This block design is suitable for brick pressing.

[0104] The present invention, through the modification of the front wall of the block body, and the outer wall surface 20a of the portal frame 20 on the same slope, organically combines the neat and orderly shape and the locking function, overcoming the problem that existing blocks of the same shape cannot achieve a neat and orderly shape when building retaining walls.

[0105] In the above embodiments, the present invention achieves a neat and orderly retaining wall constructed from masonry blocks through the following measures: the front wall of the main body is a deformed front wall and / or the first toothed block is a deformed toothed block. Among these, the embodiments involving the addition of supplementary blocks and the formation of oblique cut surfaces all fall under the category of deformed front walls. In the present invention, the neat and orderly retaining wall formed by the masonry block construction includes the formation of steps and a smooth slope.

[0106] The above description of embodiments of the present invention is not intended to limit the invention. Those skilled in the art will recognize that the present invention can have various modifications and variations. Any modifications or variations made within the scope of the present invention should be included within the protection scope of the present invention.
