Description

Technical Field

[0001] The invention relates to a retaining wall brick. Background Art

[0002] Compared with concrete retaining walls, retaining bricks (blocks) can be dry-stacked to form retaining walls / slope protection, which is easy to construct on site. At the same time, the bricks are heavy and the structure is interlocked, so the retaining wall is also more stable, and its engineering application is becoming increasingly widespread.

[0003] Chinese patent document CN202030431426.9 discloses a single-head double-lock retaining wall brick, such as Figure 23 As shown, the brick body has a cavity 15' in the middle, a front wall 11', a rear seat 12', left and right side ridges 13' / 14', and left and right symmetrical side wings 16'. The top surfaces of the left and right side ridges 13' / 14' each form a boss 17', and the inner wall of the rear seat 12' is a slope surface 21'.

[0004] When the retaining wall bricks are built, each layer of retaining wall bricks is placed straight and aligned, and the retaining wall bricks of different layers are horizontally staggered and placed front to back. The adjacent two bosses 17' of two adjacent retaining wall bricks on the same layer just fall into the positioning hole cavities 15' of the retaining wall bricks of the upper layer, and the slope surface 21' of the inner wall of the rear seat can position the stop boss 17', thereby forming a locking relationship.

[0005] The locking structure of the rear seat inner wall slope and the boss used in the above retaining wall bricks has certain limitations. For example, the slope of the rear seat inner wall is too gentle and is difficult to be processed by a brick machine. In addition, the retaining wall bricks can only be stacked with a fixed slope and cannot meet the slope change requirements on the masonry site. Summary of the Invention

[0006] The invention aims to provide a retaining wall brick to meet the on-site laying requirements of retaining walls with various slopes.

[0007] To this end, the present invention provides a retaining wall brick, the main body of which is a central axis symmetrical structure, the center of the main body is a cavity, and has a front wall, a rear seat, a left ridge, and a right ridge, and horizontally symmetrical side wings on both sides of the main body, the top surfaces of the left ridge and the right ridge respectively forming a slope-changing lock structure, the slope-changing lock structure includes a front boss and a rear boss arranged on the side ridge between the side wings and the rear seat, and a groove is formed between the two bosses, the slope-changing lock structure also includes a limit block extending into the cavity at the groove position of the left ridge and the right ridge, wherein the width of the limit block is smaller than the width of the groove, and the slope-changing lock structure forms two forms when the retaining wall bricks are stacked to form a retaining wall. The first form is a vertical retaining wall, at this time, the limit block of the retaining wall brick of the upper layer is placed in the groove of the two adjacent retaining wall bricks of the lower layer; the second form is a steep slope retaining wall, at this time, the front boss and the rear boss of the two adjacent retaining wall bricks of the same layer are both placed in the cavity of the retaining wall brick of the upper layer and are locked by the limit block.

[0008] Compared with the prior art, the present invention has the following technical effects / advantages:

[0009] 1. The product can be stacked into vertical walls and retaining walls of different slopes; 2. The limit block design is adopted to avoid the situation where the back seat slope is too slow and affects the mechanical processing and forming; 3. The product forms a closed inner cavity through the adjustment of the leak-proof blocks and the limit blocks, and there will be no leakage when filling; 4. The boss of the product meets the design of ultra-high boss processing technology. The height of the boss can reach more than 3CM. Theoretically, the height can reach 10CM or even higher, and it can obtain satisfactory appearance and strength, overcoming the defects of the existing dry concrete brick machine production, that is, the maximum height of the boss does not exceed 3CM, the density and integrity of the boss are poor, and the locking relationship formed is unstable.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] Figures 1 to 7 The present invention shows a retaining wall brick according to a first embodiment, wherein the main body of the retaining wall brick is a central axis symmetrical structure; the main body is composed of a front wall 11, a rear seat 12, left and right side ridges 13 and 14, with a cavity 15 in the middle; there are laterally symmetrical side wings 16 (i.e., a first pair of side wings) on both sides of the main body, and the position of the side wings 16 is lower than the front wall 11; there are two bosses on each of the left and right side ridges 13 and 14 of the main body, and a groove 19 is formed between the front boss 17 and the rear boss 18. A limit block 20 is provided between the left and right side ridges 13 and 14 where the two grooves are located, and the two limit blocks are connected into a whole plate. The width of the limit block 20 is smaller than the width of the groove 19; the width of the front wall 11 is smaller than the distance between the front and rear bosses 17 and 18.

[0037] After the lower blocks 1 and 2 are aligned and stacked, the upper block 3 and the lower blocks 1 and 2 are stacked in a staggered manner in the horizontal direction. When the upper and lower blocks are stacked, the relative positions of the upper and lower blocks can be in three forms:

[0038] 1. Vertical retaining wall form: The front wall of the upper block is flush with the front wall of the lower block, and the limit plate is placed in the groove of the two adjacent blocks to achieve the stop locking of the front and rear positions of the upper block and the lower block, such as Figure 3 As shown;

[0039] 2. Steep slope retaining wall form: The four bosses of the adjacent blocks in the lower layer can be accommodated in the cavity between the limit plate and the front wall of the upper block, so as to realize the stop locking of the front and rear positions of the upper and lower blocks. Figure 4 As shown;

[0040] 3. Gentle slope retaining wall form: The front wall of the upper block is placed in the groove of the two adjacent blocks of the lower layer, so as to realize the stop locking of the front and rear positions of the upper block and the lower block. Figure 5 shown.

[0041] The above retaining wall forms can be used alone or in combination, such as Figure 7 As shown, the vertical retaining wall changes into a steeper retaining wall.

[0042] In this embodiment, the length of the sealing block 21 is slightly less than the spacing between the side ridges of adjacent lower-layer blocks, and the width of the sealing block 21 is not less than or close to the distance from the inner side of the main body front wall 11 to the front wall of the side wing 16. This prevents leakage from the bottom of the block cavity when the retaining wall is in a vertical configuration. In other retaining wall configurations, the transversely symmetrical side wings 16 also prevent leakage from the block cavity.

[0043] In this embodiment, the main body rear seat 12 is in a shape of being interrupted in the middle, and the main body rear seat extends laterally to both sides of the main body to form a second pair of side wings 22 .

[0044] In the prior art, the rear seat slope cooperates with the lower boss to achieve the function of stopping the brick body from shifting forward. However, the slope of the retaining wall cannot be too gentle, because if the slope of the retaining wall is too gentle, it is equivalent to requiring the slope to be too gentle, which makes it difficult to form the product during mechanical pressing. In the present invention, the function of the retaining wall slope size is achieved by designing the position of the limit block.

[0045] Figures 8 to 10 The second embodiment of the present invention is shown in FIG. The difference from the first embodiment is that the two limit blocks 20 are disconnected in the middle and the rear seat 12 is continuous as a whole. Figure 10 As shown, the retaining wall bricks of this embodiment are laid in a form of: first a steep slope retaining wall form, and then a vertical retaining wall form.

[0046] Figure 11 The third embodiment of the present invention is shown in FIG. The difference from the first embodiment is that the two limit blocks 20 are connected into a whole, and the rear seat 12 is continuous as a whole.

[0047] Figure 12 A fourth embodiment of the present invention is shown. The rear seat 12 of the first embodiment extends horizontally outward from both sides of the body to form a second pair of laterally symmetrical side wings 22. The difference from the first embodiment is that the rear seat 12 is flush with the left ridge 13 and the right ridge 14, and no side wings are formed.

[0048] Figure 13 A fifth embodiment of the present invention is shown, which differs from the second embodiment in that the rear seat 12 is flush with the left bank 13 and the right bank 14 and does not form side wings.

[0049] Figure 14 A sixth embodiment of the present invention is shown, which differs from the third embodiment in that the rear seat 12 is flush with the left bank 13 and the right bank 14 and does not form side wings.

[0050] Figures 15 to 17The seventh embodiment of the present invention is shown. The first pair of side wings 16 of the first embodiment are located between the front wall 11 and the front boss 17, and are spaced apart from the front wall 11 so that the top surface of the cavity of the next layer of retaining wall bricks can be partially exposed when building the vertical retaining wall. The difference between this embodiment and the first embodiment is that the first pair of side wings 16 are located on the left and right sides of the front wall 11 and are arranged flush with the front wall 11.

[0051] Figure 18 and Figure 19 An eighth embodiment of the present invention is shown, which differs from the first embodiment in that a first pair of side wings 16 are located on the left and right sides of the front wall 11 and extend outward relative to the front wall 11 to form a matrix-filled groove 23 .

[0052] Figure 20 The ninth embodiment of the present invention is shown. The difference from the first embodiment is that the first embodiment is a single-end brick, while this embodiment is a double-end brick, consisting of two single-end bricks connected in parallel.

[0053] Figure 21 The tenth embodiment of the present invention is shown. The difference from the second embodiment is that the second embodiment is a single-end brick, while the tenth embodiment is a double-end brick, which is composed of two single-end bricks connected in parallel.

[0054] In the present invention, the two front protrusions of the left and right side ridges are on the same horizontal line, and the two rear protrusions of the left and right side ridges are also on the same horizontal line, which facilitates the requirement of scraping off the remaining material (excess material) in the same direction after the material is laid during the brick machine pressing and forming process.

[0055] In the existing technology, the maximum height of the protrusion molding does not exceed 3CM. The surface of the brick where the protrusion is located is uneven and the density is poor. The existing molding process is: the top surface of the bottom film is flat, and the material is scraped with a stepped scraper after laying, and then the top mold is pressed and demolded.

[0056] The blocks of the present invention are manufactured using a multi-platform, stepped block pressing mold. The base mold comprises multiple platforms 1a, 1b, 1c, 1d, and 1e, with adjacent platforms having different step heights. Each platform forms a plurality of mold cavities 10a, 10b, 10c, 10d, and 10e. The cavity of the higher platform, such as the lower portion of cavity 10b, communicates with the cavity of the adjacent lower platform, such as cavities 10a and 10c. During the brickmaking process, the material is first applied to the base mold, followed by scraping off the excess material at each step. The top mold then compacts the material in the cavities of each platform. Finally, the base mold is removed, followed by the top mold, to produce retaining wall bricks with raised blocks.

[0057] In the molding process of the present invention, the molding material of the retaining wall brick protrusion is constrained by the high platform mold cavity, the protrusion does not collapse during the material distribution and pressing process, the density of the protrusion is consistent with the brick body, and the height of the protrusion is determined by the mold size, which can exceed the existing process.

[0058] The present invention adopts a brick making method that breaks the height limit of traditional protrusion pressing and forming. The height of the two front protrusions on the left and right side ridges can reach 3-10 cm, preferably 4-8 cm, and the top surface of the brick is dense and flat, consistent with the strength of the brick body.

[0059] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modification, substitution, or improvement made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
