Description

Technical Field

[0001] The invention relates to the field of water conservancy building blocks and ecological landscape, and in particular to a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly. Background Art

[0002] At present, conventional interlocking ecological slope protection bricks generally adopt a partially locked structural design. For example, the patented technology with application number "202321159008.3": an inclined hole interlocking ecological slope protection brick. When this type of brick is laid on a slope, the protruding part of the edge of the brick is embedded in the interlocking notch of another adjacent brick. After embedding, the bricks form a whole piece on the slope surface, and the structural strength is good. However, this technology has the following defects:

[0003] Due to weather reasons (such as cold climate, etc.), the bricks will experience ice expansion (mostly occurs in the north). Once ice expansion occurs, since the bricks are tightly fitted together, only a small relative displacement can occur between the bricks. Therefore, during the ice expansion, the bricks may be damaged. Since the ice expansion occurs many times and repeatedly, the bricks are more likely to be damaged.

[0004] Based on this, it is necessary to develop a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly to overcome the above technical problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a chain-type ecological slope protection brick and a chain-type ecological slope protection brick assembly, which effectively overcomes the defects of the prior art.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, an angle α is formed between the slope surface and the main body, and 105°≤α≤120°.

[0010] Furthermore, the cross-sectional shape of the above-mentioned engaging portion is an isosceles trapezoid.

[0011] Furthermore, the cross-sectional shape of the above-mentioned engaging portion is a right-angled trapezoid.

[0012] Furthermore, the above-mentioned interlocking ecological slope protection bricks are concrete bricks with a concrete grade of C40 or above and a frost resistance grade of F300 or above.

[0013] Furthermore, the main body is provided with a first through hole passing through both ends thereof, the two ends of the main body are respectively provided with a second through hole passing through the two above-mentioned engaging parts at the corresponding ends, and the middle area of ​​the main body is provided with two third through holes passing through both sides thereof.

[0014] The beneficial effects are: the structural design is simple and reasonable, the bricks can be effectively interlocked and laid to form a whole surface, and at the same time, the design of the first slope surface can enable the bricks to move relatively and expand along the first slope surface when frost expansion occurs in cold weather, effectively relieving the frost expansion force and avoiding damage to the bricks and the overall paving.

[0015] A chain-type ecological slope protection brick assembly is also provided, comprising a plurality of chain-type ecological slope protection bricks, wherein the plurality of the chain-type ecological slope protection bricks are arranged into a plurality of rows, a shrinkage gap is formed between the ends of the main bodies of two adjacent chain-type ecological slope protection bricks in each row, the two engaging parts at one end close to each other of two adjacent chain-type ecological slope protection bricks in each row extend into the chain notch of one of the chain-type ecological slope protection bricks in an adjacent row, and among the three, the first slope surfaces of the engaging parts of the chain-type ecological slope protection bricks in two adjacent rows fit together, and a hollow ecological hole is formed between the three.

[0024] 1. Brick body; 11. Main body; 12. Fitting part; 13. Interlocking notch; 111. First through hole; 112. Second through hole; 113. Third through hole; 201. Ecological hole. DETAILED DESCRIPTION

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Example: Figure 1 and 2 As shown, the interlocking ecological slope protection bricks of this embodiment include an "I"-shaped brick body 1, and the brick body 1 includes a rectangular main body 11. The two ends of the main body 11 are close to the end portions and are respectively provided with engaging portions 12 extending vertically and symmetrically toward both sides. The surfaces of the two engaging portions 12 on the same side that are close to each other are both set as the first slope surface, and an isosceles trapezoidal interlocking notch 13 is formed between the two engaging portions 12 on the same side and the main body 11.

[0027] The interlocking ecological slope protection brick of this embodiment adopts a special structural design. The brick body 1 is designed as an I-shaped brick body. The two sides of the two ends of the main body 11 respectively form an axisymmetrically distributed interlocking part 12. The inner side of the interlocking part 12 is set as a first slope surface. When the brick bodies 1 are assembled and interlocked, an interlocking notch 13 will embed an interlocking part 12 of two identical brick bodies 1, that is, the interlocking parts 12 of the brick bodies 1 and the brick bodies 1 will be close to each other (that is, the two first slope surfaces are in contact with each other). In this way, when ice expansion occurs, the first slope surfaces of the two adjacent brick bodies 1 can slide relative to each other, so that the brick bodies can be opened, the ice expansion force is effectively released, and damage to the whole is avoided.

[0028] In this embodiment, an angle α is formed between the slope surface and the main body 11 , and 105°≤α≤120°.

[0029] In this embodiment, the shape of the interlocking ecological slope protection bricks has at least the following two structural designs:

[0030] 1) The cross-sectional shape of the above-mentioned engaging portion 12 is an isosceles trapezoid, that is, the inner and outer sides of each engaging portion 12 are designed as first slope surfaces.

[0031] 2) The cross-sectional shape of the above-mentioned engaging portion 12 is a right-angled trapezoid, that is, only the inner side of each engaging portion 12 is designed as a first slope surface.

[0032] In this embodiment, the above-mentioned interlocking ecological slope protection bricks are cast and formed with concrete with a concrete grade of C40 or above and an antifreeze grade of F300 or above, which can solve the problem of concrete freeze-thaw damage. After casting, the thickness of the brick body 1 is between 12 cm and 20 cm, which can be adjusted according to different use environments. Of course, the above-mentioned grades are only the preferred scheme of this embodiment. In the actual construction and production process, the concrete grade and antifreeze grade can be adjusted in accordance with the relevant national or industry standards, or can be adjusted in accordance with the requirements of the project owner or design unit in accordance with the standards.

[0033] As a preferred embodiment, the main body 11 is provided with a first through hole 111 passing through both ends thereof, the two ends of the main body 11 are respectively provided with second through holes 112 passing through the two engaging portions 12 at the corresponding ends, and the middle area of ​​the main body 11 is provided with two third through holes 113 passing through both sides thereof.

[0034] In the above embodiment, the design of the first through hole 111 and the second through hole 112 can reduce weight on the one hand, and on the other hand, multiple interlocking bricks 1 can be connected vertically and horizontally by respectively arranging flexible connectors in the first through hole 111 and the second through hole 112, thereby improving the structural strength after laying.

[0035] Example 2

[0036] like Figure 2 As shown, the interlocking ecological slope protection brick assembly of this embodiment includes multiple interlocking ecological slope protection bricks in Example 1, and the multiple interlocking ecological slope protection bricks are arranged into multiple rows. A shrinkage gap (indicated by L in the figure) is formed between the ends of the main parts 11 of two adjacent interlocking ecological slope protection bricks in each row, and the two interlocking parts 12 at one end close to each other of the two adjacent interlocking ecological slope protection bricks in each row extend into the interlocking notch 13 of one of the interlocking ecological slope protection bricks in an adjacent row, and among the three, the first slope surfaces of the interlocking parts 12 of the interlocking ecological slope protection bricks in two adjacent rows fit each other, and a hollow ecological hole 201 is formed between the three.

[0037] In the interlocking ecological slope protection brick assembly, the interlocking parts 12 of the two interlocking ecological slope protection bricks in the same row, which are close to one end of each other, are embedded in the interlocking notch 13 of a interlocking ecological slope protection brick in an adjacent row, and the first slope surfaces inside the interlocking parts 12 are fitted together. After paving, a shrinkage gap is formed between the two adjacent interlocking ecological slope protection bricks in the same row. The shrinkage gap cooperates with the design of the first slope surface (the first slope surfaces fit together), so that in cold seasons or weather, when ice expansion occurs on the brick body 1, relative sliding and expansion can occur between the brick bodies 1 and the brick bodies 1, thereby effectively releasing the ice expansion force and reducing damage.

[0038] In this embodiment, the ecological hole 201 accounts for about 12% of the area of ​​the assembly (that is, the porosity accounts for 12% of the area of ​​the entire assembly), and the size can be optimized and adjusted as needed to achieve a landscaping effect.

[0039] As a preferred embodiment, the first through holes 111 of the plurality of interlocking ecological slope protection bricks in the same row are connected and are penetrated by a first connecting rope.

[0040] In the above embodiment, the first through holes 111 in the same row are axially connected and are penetrated by first connecting ropes, so that the brick bodies 1 in the same row are strung together by the first connecting ropes to improve the connection strength between them.

[0041] As a preferred embodiment, the two third through holes 113 of a single interlocking ecological slope protection brick are respectively connected to the second through holes 112 at both ends of an adjacent row of interlocking ecological slope protection bricks, and are respectively penetrated by a second connecting rope.

[0042] In the above embodiment, after the brick body 1 is laid, the second through holes 112 of the two adjacent rows of brick bodies 1 are connected and strung together by the second connecting ropes, and the series connection of the first connecting ropes is coordinated, so that the entire assembly is connected to each other in the longitudinal and transverse directions through the first connecting ropes and the second connecting ropes, and the integrity is better, and the interlocking strength is better after laying.

[0043] In this embodiment, the first connecting wire rope and the second connecting wire rope are both steel strands. Since the steel strands themselves have certain toughness and certain shrinkage properties, after the ice expansion bricks 1 slide apart from each other, the steel strands can pull the ropes to a certain extent. After the ice expansion stops and recovers, the steel strands can recover and shrink by themselves, driving the bricks 1 in the assembly to return to their original positions to a certain extent.

[0044] Of course, in this embodiment, the first connecting rope and the second connecting rope include but are not limited to steel strands, high-galvanized steel wires, steel bars, etc.
