Description

Technical Field

[0001] This invention relates to wall tiles, and more particularly to a multi-spacing interlocking wall tile and a structural wall formed by assembling multi-spacing interlocking wall tiles. Background Technology

[0002] In civil engineering construction, the wall thickness is usually selected according to different load-bearing conditions. Taking small red bricks as an example, different wall thicknesses can be formed by arranging the bricks in combination of length and width.

[0003] During the wall construction process, each brick needs to be bonded with cement adhesive on two or three sides before being laid. This process is commonly known as grouting. At the same time, the thickness of the grout needs to be adjusted according to the verticality of the wall and the horizontality of each layer of bricks. This process requires a lot of time and labor, and consumes a lot of cement.

[0004] To achieve stability, some industry practitioners have proposed interlocking structures between bricks. For example, Chinese patent document CN104264888 A discloses a new type of interlocking energy-saving hollow brick, which requires cement mortar bonding between the upper and lower layers. CN 209413043U discloses another new type of interlocking energy-saving hollow brick, where the upper and lower layers are fixed using protrusions and grooves. However, this method has relatively weak stability, as the blocks cannot be interlocked horizontally, making it impossible to secure the bricks. Furthermore, these wall bricks lack adaptability to changes in wall thickness and the ability to deform under various wall structures. Additionally, the horizontal misalignment of the upper and lower layers of bricks disrupts the aesthetically pleasing uniformity of the brick surface.

[0005] The prior art CN203866846U discloses a support structure spliced ​​with box-type support units. Although this structure can be stacked into a support structure that is larger at the bottom and smaller at the top, the overall shape of this structure is monotonous, the volume shrinks too quickly at the top and bottom, the application range is narrow, the gap is shallow, the overturning resistance is weak, and the stability is not high.

[0006] Therefore, it is necessary to provide a new type of wall brick to innovate the existing wall building process and application functions. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-spacing interlocking wall brick and a structural wall formed by assembling multi-spacing interlocking wall bricks.

[0008] To address this, the present invention provides a multi-spacing interlocking wall tile. This wall tile has a flat top and bottom and a straight-up-down shape. It includes a wall surface and multi-spacing interlocking heads. The multi-spacing interlocking heads are located on one side of the wall surface and have a first sidewall and a second sidewall. Each of the first and second sidewalls has a locking structure. The locking structure is formed by multiple alternating sets of protruding teeth and grooves relative to the wall surface. The wall surface has left and right end faces. The positional relationship between the wall surface and the multi-spacing interlocking heads satisfies the following: when two wall tiles are placed in the same direction, with their wall surfaces at the same height and their left and right end faces touching, a multi-spacing interlocking groove is formed between the multi-spacing interlocking heads of the two wall tiles. The multi-spacing interlocking heads are engaged with the multi-spacing interlocking groove.

[0009] According to another aspect of the present invention, a novel structural wall is provided, comprising unit A and unit B, and is formed by stacking multiple layers of unit A and multiple layers of unit B. All wall bricks in unit A and unit B are in the same row and of equal height, with flush wall surfaces, and their left and right ends are attached and facing the same side. When the wall is being built, unit A and unit B face opposite directions, with their wall surfaces facing outwards. Unit A and unit B have a height difference of half a wall brick. The multi-slot head of unit A engages with the multi-slot groove of unit B, and the multi-slot head and multi-slot groove can form different spacings by selectively engaging protrusions and grooves. The wall bricks are the aforementioned multi-slot interlocking wall bricks.

[0010] This invention also provides a building block toy wall tile, which has a flat top and bottom and a straight-up-down shape. The wall tile includes a wall surface and a multi-slotted locking head. The multi-slotted locking head is located on one side of the wall surface and has a first sidewall and a second sidewall. Each of the first and second sidewalls is provided with a locking structure. The locking structure is composed of multiple sets of protruding teeth and grooves arranged in sequence from far to near relative to the wall surface. The wall surface has left and right end faces, and the positional relationship between the wall surface and the multi-slotted locking head satisfies the following: when two wall tiles are placed in the same direction, with the wall surfaces at the same height and the left and right end faces touching, a multi-slotted locking groove is formed between the multi-slotted locking heads of the two wall tiles, wherein the multi-slotted locking head is satisfied to engage with the multi-slotted locking groove.

[0011] The multi-slot interlocking wall bricks of the present invention have a unique external structure and allow the multi-slot head and multi-slot groove to be connected in multiple slots to form a prefabricated structural wall with different thicknesses and all-round interlocking.

[0012] The wall structure of this invention adopts a prefabricated wall-building process, which saves time and a lot of labor and greatly reduces the use of cement. This structure not only improves the seismic performance, but also enhances the structural strength and sound insulation of the wall, which is in line with the concept of low carbon and environmental protection.

[0013] This invention can be applied in various fields:

[0014] 1) In the field of building construction, it can be used to build vertical walls of different thicknesses;

[0015] 2) In the field of concrete retaining wall application, different types of retaining walls can be built, such as retaining wall structures with smaller upper parts and larger lower parts with varying thicknesses. These can replace traditional gravity retaining walls. The retaining walls are highly flexible and earthquake-resistant, can adapt to deformation caused by localized concentrated stress, have a permeable wall structure, allow for rapid drainage, and have almost zero water pressure behind the wall.

[0016] 3) It can be built into inclined retaining walls with different slopes, which can be used for slope protection and have strong anti-sliding and anti-overturning capabilities.

[0017] 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

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] Figures 1 to 9 The invention illustrates a multi-spacing snap-fit ​​wall brick and a novel structural wall assembled from the wall brick, according to Embodiment 1 of the present invention.

[0045] This multi-slot interlocking wall brick has a flat top 1a and a flat bottom 1b and a straight-up and down shape structure, that is, the wall brick has a shape that extends with a uniform cross section along the vertical direction, including a wall surface 11 and a multi-slot interlocking head 12 that is centrally located on the inner side of the wall surface 11.

[0046] The wall surface 11 is rectangular, with the left end face 11a and the right end face 11b being straight walls, serving as the reference surfaces for aligning and placing adjacent wall bricks.

[0047] Three grooves 121 are spaced apart on the first sidewall 12a and the second sidewall 12b of the multi-slot card head 12. The portion of the sidewall is reserved to form a tooth 122, and thus multiple sets of teeth 122 and grooves 121 are formed on the sidewall, thereby forming a locking structure in which the teeth 122 and grooves 121 are arranged alternately three times.

[0048] The aforementioned protruding teeth 122 and grooves 121 extend vertically through the flat top and bottom of the wall bricks, that is, the protruding teeth 122 are straight teeth blocks that go straight up and down, and the grooves 121 are straight teeth grooves that go straight up and down and are adapted to the shape of the protruding teeth.

[0049] In this invention, the locking structure formed on the first and second sidewalls of the multi-slot card head 12 is a left-right symmetrical structure.

[0050] The width between the left and right end faces of the wall surface 11 is greater than the width of the multi-slot card head 12 and satisfies the following: when two adjacent wall bricks are placed side by side, a multi-slot card groove 13 is formed between the multi-slot card heads of the two wall bricks, which allows the multi-slot card head 12 of another wall brick placed opposite to it to engage with the multi-slot card groove 13, and allows three-slot engagement.

[0051] Figure 4 The diagram shows the full-slot engagement of the multi-slot card head 12 and the multi-slot card slot 13. Figure 5 This illustrates a snap-fit ​​method in which the multi-spacing card head and the multi-spacing card slot are separated by one spacing. Figure 6 This illustrates a snap-fit ​​method in which the multi-slot card head and the multi-slot card slot are separated by two slots.

[0052] Combined with reference Figures 7 to 9 The novel structural wall of the present invention includes multiple A units 1 and multiple B units 2, which are placed opposite each other and staggered by half a brick in both the horizontal and vertical directions. Thus, the inner and outer wall bricks are interlocked by the interlocking of the multi-slotted slots 13 and the multi-slotted head 12.

[0053] Specifically, in Unit A1 (i.e., the same layer of wall tiles facing outwards), all wall tiles are in the same row at the same height, with the wall surfaces aligned, and the left and right ends touching and facing the same side. The same applies to Unit B2 (i.e., the same layer of wall tiles facing inwards). Unit A1 forms a structure in which the multi-spacing card heads 12 and multi-spacing card slots 13 are arranged in sequence. The same applies to Unit B. The two are placed opposite each other, meaning that the multi-spacing card heads 12 of the inner and outer layers of wall tiles point to each other.

[0054] The inner and outer wall tiles are placed horizontally with a half-tile offset, so that the multi-slotted grooves can be engaged with the multi-slotted heads of the opposite wall tiles.

[0055] The inner and outer wall tiles are also staggered by half a tile in the height direction, so that unit A1 can simultaneously engage with the two upper and lower units B2. Unit B2 is also staggered with the two upper and lower units A1. In one embodiment, either the bottom unit A or unit B is a half-thick wall tile, thereby achieving the effect of staggered placement in the height direction.

[0056] In this new type of structural wall, interlocking relationships are formed between the inner and outer layers of wall bricks, as well as between the upper and lower layers of wall bricks on the same side, making the overall wall structure very stable.

[0057] The wall bricks in this embodiment can be stacked to form a wall with uniformly flat inner and outer surfaces. These wall bricks can also be applied to retaining walls to form combinations such as retaining walls of equal thickness, retaining walls of varying thickness, or stepped retaining walls.

[0058] Figure 7 The diagram shows a two-tiered retaining wall, wider at the bottom and narrower at the top, constructed by interlocking bricks at different intervals. It consists of wall 101 and wall 2 102 with increased thickness, and the bricks interlock at the joints of different walls. Figure 8 The diagram shows a three-tiered retaining wall constructed of interlocking bricks, with progressively wider sections at the top, middle, and bottom. The wall consists of wall 3 (111), wall 4 (112), and wall 5 (113), with the bricks interlocking at the joints of the different walls. Figure 9 The diagram shows a stepped retaining wall 120 constructed from interlocking bricks of different spacing, where different bricks interlock.

[0059] The wall tiles in this embodiment adopt a straight-up-and-down contour shape and are very simple in shape, presenting a "king" character shape, which is suitable for the concrete powder pressing molding process and also suitable for the mud brick extrusion molding process.

[0060] When the wall tiles in this embodiment are used to build walls of equal thickness, the outer wall surface and the inner wall surface are aligned left and right and up and down respectively, being neat and uniform, breaking the inertial thinking and perception that the brick surfaces of existing wall tiles are misaligned due to interlocking.

[0061] In some application scenarios, to avoid the loosening of wall tiles caused by the fitting gaps between wall tiles, traditional mortar can be used to fill the gaps between the convex teeth and the grooves, realizing the bonding and firm fixation between wall tiles.

[0062] Embodiment Two

[0063] Figure 10 Shows the multi-spacing snap-in wall tiles of Embodiment Two of the present invention.

[0064] This Embodiment Two is a variant structure of Embodiment One. Among them, in Embodiment One, a straight-up-and-down through hole 12c is provided in the middle of the multi-spacing snap-in head. In this Embodiment Two, the multi-spacing snap-in head 12 is a solid component.

[0065] Embodiment Three

[0066] Figures 11 to 14 Shows the multi-spacing snap-in wall tiles of Embodiment Three of the present invention and a new structure wall assembled by these wall tiles.

[0067] This Embodiment Three is a variant structure of Embodiment One. Among them, the convex teeth in Embodiment One are rectangular blocks. In this Embodiment Three, the convex teeth 122 are in the shape of being larger outside and smaller inside on one side (b > a), that is, the whole is in the shape of a boot. At the same time, the groove is adapted to the shape of the convex teeth and is also in the shape of being larger outside and smaller inside on one side.

[0068] The use of this convex tooth enables a lateral interlocking relationship to be formed between two adjacent wall tiles on the left and right. Two adjacent wall tiles on the same layer cannot be separated, forming an all-round interlocking, making the wall structure more stable.

[0069] Figure 12 Shows the wall structure One 201 of the first thickness (full groove snap-in method) assembled by the wall tiles in this embodiment. Figure 13 Shows the wall structure Two 202 of increased thickness (pulling apart one spacing snap-in method) assembled by the wall tiles in this embodiment.

[0070] Embodiment Four

[0071] Figures 15 to 16Shows the multi-span snap-together wall tiles of the fourth embodiment of the present invention and the structural wall formed by assembling these wall tiles.

[0072] The fourth embodiment is a variant structure of the second embodiment. In this embodiment, two grooves 121 are spacedly provided on the first side wall and the second side wall of the multi-span snap head, thereby forming a locking structure in which the convex teeth and the grooves are alternately arranged twice in the thickness direction of the wall tile.

[0073] At this time, when two adjacent wall tiles are placed side by side and aligned, a multi-span slot portion (i.e., two spans) is formed between the multi-span snap heads of the two wall tiles. This allows the multi-span snap head of another wall tile to be inserted into this multi-span in a vertical snap-together manner and allows two-span snap connection.

[0074] The wall tile of this embodiment is in the shape of a "king", commonly known as the "big king brick", and the brick shapes of other embodiments are simple deformations of it and can also be called the "big king brick".

[0080] This embodiment is a variant structure of the first embodiment. The wall tile of the first embodiment is a flat wall tile for building a flat wall, and the wall tile of the sixth embodiment is a corner tile for building a vertical corner.

[0081] Among them, the wall surface 11c of the wall surface portion 11 of this wall tile is a right-angle transition surface. Similar to the first side wall and the second side wall of the first embodiment, the multi-span snap head 12 has a first side wall 12a and a second side wall 12b that are perpendicular to each other. The first side wall 12a faces the first-direction wall 301, and the second side wall 12b faces the second-direction wall 302. A locking structure formed by alternately arranging the convex teeth and the grooves more than twice is respectively formed on the first side wall 12a and the second side wall 12b.
