Description

Technical Field

[0001] The present invention relates to a block assembly formed of a plurality of blocks and constituting at least a part of a wall, a fence or a door jamb.

Background Art

[0002] In the conventional construction method, a wet construction method is used in which concrete is placed in a formwork, or concrete blocks are juxtaposed and laminated and joined using mortar to form a wall-like structural base material having an appropriate thickness and height, and decorative members such as tiles and bricks are pasted on the front, rear, or side surfaces thereof using mortar or an adhesive to erect a wall, a fence or a door jamb.

[0003] There is also a construction method in which a colored mortar or a coating material made by mixing sand or the like into a paint to make it mortar-like is sprayed or applied using a trowel or a roller on the surface of the structural base material to erect a wall, a fence or a door jamb.

[0004] In addition, a dry construction method in which a wall unit prefabricated in a factory is carried into the site and installed, and a dry construction method in which a structural base material manufactured in a factory is erected and an exterior tile panel or the like is attached to the surface thereof have been devised.

[0005] For example, in Patent Document 1, a method has been devised in which a ceramic siding is attached to the surface of a metal housing frame using tapping screws and a foamed synthetic resin is filled in the inner hollow portion. Further, in Patent Document 2, a method has been devised in which a panel base material having ribs for supporting tiles is integrally formed using a foamed resin, and the surface tiles are hooked on the supporting ribs of the panel base material by grooves provided on the back surface thereof, and further fixed using an adhesive.

[0007] However, structural base materials erected using conventional methods, including wet construction methods such as pouring concrete into formwork or stacking concrete blocks side by side, or dry construction methods such as erecting structural base materials produced in a factory, tend to have a monotonous design based on a flat plane, and at best are limited to the repetition of small irregularities on the surface of the concrete blocks. Therefore, the object of the present invention is to provide a block assembly that can form a three-dimensional and integrated design with a high degree of freedom using multiple blocks, and a method for manufacturing the same. A block assembly can also be called a block structure. [Means for solving the problem]

[0008] The block assembly of the present invention is a block assembly formed by arranging or stacking a plurality of blocks so as to constitute at least a part of a wall, fence, or gatepost, wherein a connection hole is formed on the side surface of each block through which a fastening member can be inserted, and the plurality of blocks include a plurality of design blocks or special blocks involved in the formation of a design. Each design block has the connection hole and comprises a main body formed in the shape of a rectangular parallelepiped, and a protrusion that protrudes from a part of the surface of the main body and forms a straight or curved ridge line at a position overlapping with the surface of the main body. The protrusions may be formed in different shapes from each other. Each main body forms a series of straight or curved designs on the surface of the wall, fence, or gatepost by one or more of the protrusion ridge lines, and is connected to the main body of an adjacent block by the connection hole and the fastening member so that the surfaces of the plurality of protrusions are continuous. The special block is a block in which a part including the main body of the block is missing so as to penetrate from the block surface to the rear surface, and the ridge line of the missing part forms a straight or curved ridge line in the outer shape of the block. The missing ridges may be formed in different shapes from each other. Each of the main body parts forms a series of linear or curved designs on the outer shape of a wall, fence, or gatepost with one or more of the missing ridges, and is connected to the main body parts of other adjacent blocks by the connecting holes and fastening members so that the multiple missing ridges are continuous.

[0009] The present invention provides a method for manufacturing a block assembly, comprising a manufacturing step in which a plurality of the blocks are created by a 3D printer or another block manufacturing machine other than a 3D printer, and a connection step in which an operator connects the plurality of the blocks. If the direction perpendicular to the surface of the main body is defined as the front-to-back direction, the main body is provided with a window portion that is recessed or penetrates in the front-to-back direction at a position corresponding to the connection hole, and the connection hole is a bolt insertion hole that connects the window portion to the outside. In the connection step, the operator connects the plurality of blocks using the window portion, the bolt insertion hole, and the fastening members, namely bolts and nuts, so that the design is formed. [Effects of the Invention]

[0010] According to the present invention, a series of three-dimensional designs are formed on the surface side of the block assembly by multiple protruding ridges and protruding surfaces, or on the outer shape of the block assembly by multiple missing ridges. This is achieved by connecting blocks, including design blocks or special blocks, without gaps using connecting holes and fastening members provided on the side of the main body or the side of the protrusions. The formation of connecting holes in the main body improves the degree of freedom in the shape design of the protrusions, and a series of designs are formed by multiple adjacent and continuously arranged protruding ridges or missing ridges. Note that "without gaps" means that there are no joints in wet construction (the gaps between blocks that occur when concrete blocks are laid side by side using mortar as an adhesive material).

[0011] According to the manufacturing method of the present invention, blocks other than design blocks and special blocks involved in the formation of the design (thin blocks and thick blocks described later) can be mass-produced in a factory as standardized components, and only some design blocks and special blocks can be easily and accurately formed using industrial or household 3D printers. Furthermore, blocks can be easily, reliably, and seamlessly connected to each other by bolt fastening using the window portions and connecting holes. [Brief explanation of the drawing]

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as forms for carrying out the present invention. In addition to the embodiments described below, the present invention can be carried out in various forms with various modifications and improvements based on the knowledge of those skilled in the art. In the description, the direction perpendicular to the surface of the main body may be referred to as the "front-to-back direction". The length from left to right will be referred to as the "width", the length from top to bottom as the "height", and the length from front to back as the "depth" or "thickness". "Surface" refers to the surface facing forward when viewing a wall, fence, or gatepost from the front, except when referring to the outer surface of an object, such as "surface member" or "surface finish". "Side" includes the top, bottom, left, and right surfaces, except when limited to "left and right side" or "top and bottom surfaces". Furthermore, "curved" is a concept that includes shapes in which part is straight and other parts are curved. "Straight" is a concept that includes shapes in which part is bent (for example, a V-shape). Similarly, "curved" is a concept that includes shapes in which part is flat and other parts are curved. Furthermore, the expression "or" is synonymous with "and / or," and is used to include both cases where one option is chosen from a set of choices and cases where multiple options are chosen simultaneously. [Examples]

[0014] As shown in Figure 1, the block assembly 11 is a structural base material formed by arranging or stacking multiple blocks to constitute at least a part of a wall, fence, or gatepost. The multiple blocks include one or more design blocks 12. In this embodiment, the multiple blocks constituting the block assembly 11 include multiple design blocks 12, (here, multiple) thin blocks 13, and (here, multiple) thick blocks 14. Hereafter, an assembly of multiple identical blocks will also be referred to as a block section. Note that in Figures 1 to 5, in order to clarify the explanation of the method of forming the design, connection holes, window sections, column penetration holes, and beam-internal grooves for connecting each block have been omitted and will be described later.

[0015] Figure 2 schematically shows an example of a design block in this disclosure. The shape of each design block differs depending on the desired design shape, but the basic components remain the same. The design block 21 comprises a main body 22 and a protrusion 23. The main body 22 is formed in the shape of a rectangular parallelepiped, for example, with dimensions of 400 mm in width, 120 mm in thickness, and 200 mm in height. The protrusion 23 protrudes from a part of the surface of the main body 22 with a protrusion height 24 (depth) of, for example, 30 mm, and forms a straight or curved protrusion ridge 25 at a position that overlaps with the surface of the main body 22 when the design block is viewed from the front. In this example, the protrusion ridge 25 (which may simply be called a "ridge") forms an S-shaped design by combining two arc-shaped curves. Between the surface of the main body 22 and the surface of the protrusion 23, a stepped side surface 26 (which may also be called the "protrusion stepped side surface") is formed along the ridge line 25 of the protrusion, and the stepped side surface 26 is a band-shaped curved surface whose width is equal to the height 24 of the protrusion (which may also be called the "protrusion depth").

[0016] The height of the protrusion 24 is preferably 10 mm or more and 100 mm or less. The main body 22 and the protrusion 23 are integrally formed. It is molded from a lightweight material with high moldability, such as resin (including foamed resin or artificial wood made by mixing resin with wood powder), and when all or part of the component is manufactured using a 3D printer, ASA (acrylonitrile styrene acrylic acid polymer), which has excellent weather resistance and light resistance, may be used as the material. In this embodiment, the height of the protrusion 24 (depth) is 30 mm.

[0017] The thin block 13 is a rectangular block consisting only of the main body 22 and lacking the protrusions 23, and is also called the basic block. The thick block 14 is a rectangular block in which the entire surface of the main body 22 protrudes by the same depth (protrusion height 24) as the protrusions 23 of the design block 12. In this embodiment, both are 400 mm wide and 200 mm high, with the thin block 13 having a thickness of 120 mm and the thick block 14 having a thickness of 150 mm.

[0018] Figure 3 is a front view of the block assembly 11 of Figure 1. In Figure 3, the block assembly 11 consists of a thin block section 16 composed of multiple thin blocks 13, a thick block section 17 composed of multiple thick blocks 14, and a design block section 15 composed of one or more design blocks 12, forming the structural base material of the gate pillar. The surface of the thin block section 16 and the continuous body section 22 of each block constituting the design block section 15 connect smoothly without steps between adjacent blocks, forming a body section plane 31 (the part without shaded lines in the figure, the back side plane). In addition, the surface of the thick block section 17 and the continuous convex section 23 of each block constituting the design block section 15 connect smoothly without steps between adjacent blocks, forming a convex section plane 32 (the shaded part in the figure, the front side plane).

[0019] (Formation of design) In this embodiment, the convex ridges 25 of each design block constituting the design block section 15 form a single continuous wave-like design 18 from the left end to the right end of the gate pillar. By connecting adjacent blocks without gaps using connecting holes and fastening members described later, the convex stepped side surfaces 26 of each design block and the convex stepped side surfaces 26 of other adjacent design blocks connect smoothly without any steps, forming a series of curved convex stepped side surfaces along the design 18, and connecting the surfaces of the convex portions 23 of multiple (in this case, all) design blocks in a continuous manner. Multiple staircase shapes may be formed by the convex ridges of multiple blocks, or multiple designs may be formed within a single block assembly. Thus, the convex portions can also be called design forming portions. Furthermore, when a thick block and a basic block are adjacent, the end ridges of the thick block can become part of the design.

[0020] When the block assembly is viewed from the front, the ratio of the area of ​​the convex plane to the total area of ​​the wall surface is between 10% and 90%. This means that the design in this disclosure does not refer to a repeating pattern of small irregularities on the surface (for example, a wood grain, stone pattern, or brick pattern), but rather to a design that extends to the entire structure. In this embodiment, the convex plane 32 is the area indicated by the shaded area in Figure 3, and the main body plane 31 is the remaining area. The ratio of the area occupied by the convex plane 32 to the total area of ​​the wall surface, that is, the sum of the area of ​​the convex plane 32 and the area of ​​the main body plane 31, is approximately between 40% and 50%. Note that there are connecting work windows 66 or 72 in the main body and convex parts, which will be described later, but the area of ​​each connecting work window is included in the area of ​​the main body or convex part to which the connecting work window belongs.

[0021] In this embodiment, the thick block section 17, the design block section 15, and the thin block section 16 are arranged and stacked side-by-side to form a rectangular shape in the order of 4 blocks x 2 layers, 4 blocks x 1 layer, and 4 blocks x 3 layers, respectively. However, they do not necessarily have to be rectangular in shape; they may be stacked side-by-side to form a convex or concave shape. In this embodiment, the design block section 15 is located between the thin block section 16 and the thick block section 17, and the thin block section 16 and the thick block section 17 are not directly adjacent. However, if the edges constituting the design 18 include horizontal or vertical straight lines, the thin block 13 and the thick block 14 can be placed side-by-side or stacked so that they are adjacent to each other along the straight line portion (edge), and the resulting step can be considered part of the design 18. Furthermore, depending on the design, it is also possible to construct the entire design using only the design blocks 12.

[0022] Thus, the block assembly 11 (multiple blocks) of this embodiment is composed of multiple design blocks 12, thin blocks 13 having the same front-to-back thickness as the main body, and thick blocks 14 having the same thickness as the sum of the front-to-back thickness of the main body and the front-to-back thickness of the protrusion (including cases where no thin blocks 13 or thick blocks 14 are used).

[0023] In this embodiment, the three types of blocks share a common structure that is the same shape as the main body. In other words, the main body is the basic structure common to the thin block, thick block, and design block. The thin block consists only of the basic part and will hereafter be referred to as the "basic block." The thick block consists of the basic part and a rectangular parallelepiped-shaped protrusion that extends from the entire surface of the basic part by the same length as the protrusion. The thin block can be described as a design block with no protrusions at all, while the thick block can be described as a design block with protrusions on its entire surface. Each block is made of resin and is integrally formed, for example, by a 3D printer.

[0024] In this embodiment, a recess can be formed on the stepped side surface 26 corresponding to the ridge of the protrusion. An LED lighting fixture can be placed in the recess. The recess is, for example, a groove extending along the ridge, or a plurality of holes formed along the ridge.

[0025] Figure 4 shows a portion of a juxtaposed block assembly including a continuous design 41. A groove 43 extending along the entire length of the continuous design 41 can be provided on the stepped side surface 42 of the protruding part of the design block. This groove 43 is, for example, 12 mm wide and 6 mm deep, and a long tape-shaped LED lighting fixture can be installed by fitting it into this groove 43.

[0026] Figure 5 shows a different example from Figure 4. Instead of a groove 43 that extends along the entire length of the continuous design 41, holes 51 can be provided continuously at regular intervals, and a bullet-shaped LED lighting fixture can be installed in each of the holes 51.

[0027] (Connection structure) In this embodiment, each block has a connecting hole formed on its side surface through which a fastening member can be inserted, and adjacent blocks in the block assembly are fastened together by fastening members that connect each other's connecting holes. The fastening members are, for example, bolts or press-fit pins. On the front or back surface of the main body, there are recessed or penetrating window portions that correspond to the connecting holes in the front-to-back direction. The connecting holes are bolt insertion holes that connect the window portions to the outside, and when the blocks are placed side by side or stacked, they are also in a position to communicate with the bolt insertion holes of adjacent blocks. The window portions are formed at at least one of the four corners of the surface of the main body that is not covered (exposed) by the protrusions, or at least one of the four corners of the back surface of the main body. The following will be explained in detail with specific examples.

[0028] Figure 6 shows an example of a thin block (basic block). The basic block 61 has bolt holes 62 and 63 on its left and right sides for connecting to adjacent blocks to the left or right, and bolt holes 64 and 65 on its top and bottom surfaces for connecting to adjacent blocks above or below. The bolt holes 62 and 64 are located on the rear side of the basic block, and the bolt holes 63 and 65 are located on the front side of the basic block. In this example, there are two bolt holes 62 and 63 on each of the left and right sides of the block (a total of four), and four bolt holes 64 and 65 on each of the top and bottom surfaces (a total of eight), but the leader lines in the figure only show a portion of them.

[0029] Blocks are placed side by side or stacked vertically, and bolts and nuts for connecting each block are inserted into bolt insertion holes 62, 63, 64, or 65, and the tightening work is performed. To facilitate the insertion of bolts into each bolt insertion hole and the tightening work with nuts, windows 66 (hereinafter also referred to as "connecting work windows") are provided at positions corresponding to the bolt insertion holes on the front and rear surfaces of the block. In this example, the opening shape of the connecting work window 66 is triangular, but other polygonal shapes (including circles) such as squares may also be used. In this example, there are a total of 16 connecting work windows 66, 8 on the front and 8 on the rear surfaces of the block, but the leader lines in the figure show only a portion of them.

[0030] In this embodiment, at least one of the multiple blocks has a vertically penetrating support column through-hole 67. A column member can be placed in the support column through-hole 67. In the case of a support column through-hole 67 where no column member is placed, this space may be used to route the wiring for an LED lighting fixture.

[0031] The post through-holes 67 are holes drilled to penetrate from the top surface to the bottom surface of the block. When erecting a wall, fence, or gatepost, posts embedded perpendicular to the ground are passed through the post through-holes 67. The posts are, for example, 60mm x 60mm metal square posts. In this embodiment, four post through-holes 67 are provided in one block so that the positions of the post through-holes of the upper and lower blocks coincide when the blocks are stacked with a half-block offset on top of each other.

[0032] Figure 7 shows an example of a thick block. The thick block 71 is manufactured to the same dimensions as the basic block 61, with a width of 400 mm, a height of 200 mm, and (in this embodiment) a thickness of 150 mm. The bolt insertion holes 62, 63, 64, 65, and column through holes 67 are identical to those of the basic block 61. The thick block 71 has a shape where the entire front surface of the basic block 61 is extended forward by the height of the protrusion 24 in the design block. The front connecting work window 72 is deeper than the connecting work window 66 in the basic block 61 by the extended height of the protrusion 24. In the following figures, the bolt insertion holes, connecting work windows, and column through holes belonging to the main body are given the same reference numerals as in the basic block 61.

[0033] The left and right sides of the thick block 71 are provided with bolt insertion holes 62 and 63, as well as bolt insertion holes 73 on the extended protrusions. The top and bottom surfaces of the block are provided with bolt insertion holes 64 and 65, as well as bolt insertion holes 74 on the extended protrusions. When connecting thick blocks to each other, use bolt insertion holes 73 or 74. When connecting a thick block to a basic block, use bolt insertion holes 63 or 65.

[0034] Figure 8 shows an example of a design block. The design block 81 is manufactured to the same dimensions as the basic block 61, with a width of 400 mm and a height of 200 mm. It has a mixed section with the same thickness as the basic block 61 (120 mm) and a section with the same thickness as the thick block 71 (150 mm), separated by a protruding step. The bolt insertion holes 62, 63, 64, 65, connecting work window 66, and support column through hole 67 are identical to those of the basic block 61. The protruding section has the same bolt insertion holes 73 or 74 as the thick block 71, which are used when connecting to the protruding section of an adjacent thick block or design block. In addition, the connecting work window 66 belonging to the main body is identical to the connecting work window 66 of the basic block 61, and the connecting work window 72 belonging to the protruding section is identical to the connecting work window 72 of the thick block 71.

[0035] Figure 9 shows the basic block, thick block, and design block in two halves in the width direction, each manufactured with a width of 200 mm and a height of 200 mm (for convenience, these are referred to as "basic half block," "thin half block," "thick half block," and "design half block," respectively). The basic half block 91 has a thickness of 120 mm, the thick half block 92 has a thickness of 150 mm, and the design half block 93 has a mix of 150 mm and 120 mm thicknesses separated by a protruding step. The positions of the support column through hole 67, connecting work window 66, bolt insertion hole 62, bolt insertion hole 63, bolt insertion hole 64, and bolt insertion hole 65 are the same as those of the basic block 61 when two of each half block are placed side by side. The protruding parts of the thick half block 92 and design half block 93 have bolt insertion holes 73 and 74, which are the same as those of the thick block 71 when two of each half block are placed side by side. It's also possible to have "special half-blocks," which are two-part special blocks (described later), but these can also be described as special blocks in which more than half of the basic block, thick block, or design block is missing.

[0036] In this embodiment, when forming a wall, fence, or gatepost using the basic block 61, thick block 71, design block 81, or basic half-block 91, thick half-block 92, design half-block 93, and special blocks described later, posts embedded perpendicular to the ground are used by passing them through the post-through holes 67 of each block. The posts are installed at intervals of approximately 1000 mm, for example, but beams may be installed horizontally between the posts to reinforce the posts and to prevent deflection of the blocks between the posts that are connected using bolt insertion holes 62, 63, 64, 65, 73, or 74. These beams also serve to support the weight of things like delivery boxes when they are installed inside the wall surface of the gatepost.

[0037] Figure 10 shows an example of a design block 101 with beam-enclosing grooves, which have grooves (upper beam-enclosing groove 102, lower beam-enclosing groove 103) on the upper and lower surfaces of the main body of the design block for enclosing beams. In this example, both the upper beam-enclosing groove 102 and the lower beam-enclosing groove 103 are provided, but either one alone is also acceptable. The beam is, for example, a 60mm x 60mm metal square column, and the groove is 60mm wide and 60mm deep (with some margin in reality) to match the size of the beam, and is provided to penetrate both sides of the block. The figure shows an example of a design block, but the same can be done with basic blocks, thick blocks, half blocks, and special blocks. When blocks with upper beam-enclosing grooves 102 or lower beam-enclosing grooves 103 are placed side by side, the beam-enclosing grooves are connected between adjacent blocks. The beam-enclosing groove does not necessarily have to be present only in the block on the level where the beam is located; it may be present in all blocks. Furthermore, in beam grooves where no beam members are placed, this space may be used to route the wiring for LED lighting fixtures.

[0038] Figure 11 illustrates the process of placing a design block 111 and a basic half-block 112 side by side. At the joint surface of the two blocks, bolts 113 are inserted into the bolt insertion holes 62 or 63 that communicate in the main body, using the two connecting work windows 66 on the front surface and two on the back surface of the blocks, and then fastened with nuts 114 at the connecting work window 66 of the opposite block. When the protrusions of thick blocks or design blocks are placed side by side adjacent to each other, fastening is done using bolt insertion holes 73 and connecting work windows 72. Note that only the two sets of bolts 113 and nuts 114 on the front side are shown in the figure.

[0039] Figure 12 illustrates the process of stacking design block 121 on top of the design block 111 and basic half block 112 that were fastened together in the previous section. The design block 121 and basic half block 112, which are connected in the vertical direction, are fastened by inserting bolts 113 into bolt insertion holes 64 and 65 that communicate in the main body, using two connection work windows 66 on the front and two on the back of the blocks at the joint surface of the two blocks, and fastening them with nuts 114 at the connection work window 66 of the opposite block. (Only the bolts 113 and nuts 114 on the front side are shown in the figure). Similarly, the design block 121 and design block 111, which are connected in the vertical direction, are fastened by inserting bolts 113 into bolt insertion holes 64 and 65 that communicate in the main body, and bolt insertion holes 74 that communicate in the protruding parts, and fastening them with nuts 114 at the connection work window 66 or connection work window 72 of the opposite block. Note that the diagram only shows the four sets of bolts 113 and nuts 114 on the front side.

[0040] Figure 13 shows the state after the design block 111, basic half block 112, and design block 121 have been fastened together in the previous section. At the joint where the convex ridge line 131 of design block 121 and the convex ridge line 132 of design block 111 are stacked, they are continuous without gaps or steps, forming a series of designs (or part thereof). The main body surface of design block 111, the main body surface of design block 121, and the surface of basic half block 112 form a continuous main body plane (back side plane), and similarly, the convex surface of design block 111 and the convex surface of design block 121 form a continuous convex plane (front side plane). In this way, in this disclosure, the blocks stacked side by side are connected without gaps to form a predetermined design. In conventional methods of laying concrete blocks side-by-side using a wet construction method, it is necessary to use mortar or other adhesives to bond them together, and skilled techniques are essential to ensure that the thickness of the bonding material (joint width) is consistent. However, as disclosed herein, by joining them with bolts, gaps in the joints can be eliminated, making it easy for anyone to install.

[0041] Figures 14 to 18 show the assembly process of different embodiments for forming a gate wing using the blocks of this disclosure. Since the methods for joining the blocks placed side by side and the blocks stacked vertically have been described above, some of the figures from this section onward omit the connecting work windows 66 and 72, bolt insertion holes 62, 63, 64, 65, 73, 74, and fastening members (bolts 113 and nuts 114) of each block.

[0042] Figure 14 shows an example of the use of the column through-hole 67 and the lower beam internal groove 103. A beam 143 is placed horizontally between columns 141 and 142 and fixed to the columns using beam fixing bolts 144 and 145. The design block 146 with a lower beam internal groove is installed by passing the column 141 through its column through-hole 67 and having the beam 143 straddle the lower beam internal groove 103. Similarly, a basic block 147 with a lower beam internal groove is placed next to the design block 146 with a lower beam internal groove and connected with bolts.

[0043] Figure 15 shows the state after the installation work described in the previous section, where a support column 142 is to be passed through the support column through hole 67 of the new base block 151 with a groove inside the lower beam, and installed so as to straddle the beam 143. The base block 151 with a groove inside the lower beam is fastened to the base block 147 with a groove inside the lower beam with bolts. Similarly, the support column 141 is passed through the support column through hole 67 of the thick half block 152, and the design block 153 is placed next to it, and together with the lower design block 146 or base block 147 with a groove inside the lower beam, they are connected to each other with bolts.

[0044] Figure 16 shows the state after further construction work has been carried out since the previous section. Thick half blocks 161 and design half blocks 162 are stacked in sequence, and at the very top, thick blocks with beam-internal grooves on the upper surface 163, thick blocks with beam-internal grooves on the upper surface 164, and thick blocks with beam-internal grooves on the upper surface 165 are installed. Finally, beams 166 are fitted from above into the upper beam-internal grooves of each, and then fixed to columns 141 and 142 using beam fixing bolts 167 and 168.

[0045] This embodiment relates to a structural base material for erecting walls, fences, or gateposts, and requires surface finishing to be completed. The structural base material constructed according to this embodiment has a series of designs 169 (protruding ridges) formed by the protrusions of four design blocks, a part of the lower surface of the thick block 165 with a groove inside the upper beam, and the protrusions of the design half block 162. In this embodiment, the protruding step divides the structure into a main body surface 171 with a thickness of 120 mm and a protruding surface 172 with a thickness of 150 mm, and different surface finishes can be applied to each. In this embodiment, the area occupied by the protruding surface 172 is slightly over 50% of the total area of ​​the wall surface (the sum of the area of ​​the main body surface 171 and the area of ​​the protruding surface 172).

[0046] Figure 17 shows an example of surface finishing, in which wire mesh (lath mesh 173), which serves as a base for the coating material called "lath" or "lath mesh," is installed on the main body surface 171 and the right side of the gate post. Siding panels 174, 175, and 176, cut to match the design 169 (protruding ridge line), are attached to the convex surface 172. Furthermore, coping 177 can also be installed on the top of the structural base material. Since the main focus of this disclosure is the method of constructing the structural base material, the method of fixing members such as surface finishing materials and coping will not be described in detail. However, since the material of the structural base material is resin, adhesive or tapping screws can be used, or, when used as a panel base in Patent Document 2, it can be used by fixing tile-supporting projection-like members to the surface and sides of the structural base material according to this disclosure.

[0047] Figure 18 shows an example of the configuration in which a mortar-like coating 181 is applied to a wire mesh 173 fixed to the structural base material of this embodiment, siding panels 174, 175, and 176 are attached, and a coping 177 is installed. Note that the lower parts 182 and 183 of the support columns are buried in the ground.

[0048] Figure 19 is a view of the gate post of this embodiment from below. On the convex side surfaces of the four design blocks used in this embodiment, a portion of the lower surface of the thick block 165, and the continuous convex stepped side surfaces of the design half block 162, continuous tape-shaped LED lighting fixture installation grooves 191 are provided along the design 169, and a long tape-shaped LED lighting fixture 192 can be installed in these tape-shaped LED lighting fixture installation grooves 191. Although the holes for passing the wiring of the tape-shaped LED lighting fixture are omitted, in the block corresponding to the end of the tape-shaped LED lighting fixture, for example, a through hole of an appropriate diameter can be drilled from the tape-shaped LED lighting fixture installation groove 191 toward an unused support column through hole 67 or beam internal groove, and the wiring can be passed through.

[0049] Figure 20 shows an example in which a long tape-shaped LED lighting fixture 192 is installed in a tape-shaped LED lighting fixture installation groove 191 and illuminated. Conventionally, there have been methods for installing LED lighting fixtures by retrofitting them to the wall surface, such as attaching handrail-like components to the bottom of a coping or wall, but these methods often have a retrofitted look and tend to result in monotonous designs. According to this disclosure, it is possible to erect walls, fences, or gateposts with highly original designs and obtain lighting effects that take advantage of those designs.

[0050] (Special Block) Figure 21 shows examples of a basic special block 211, a thick special block 212, and a design special block 213, each having a curved defect cross-section 214 formed in the block by a defect penetrating in the front-to-back direction. The defect cross-section 214 is composed of a flat or curved surface and forms a defect ridge line 215 on the main body surface or convex surface of each block. A feature of these blocks is that when the special blocks are placed side by side or stacked, the defect cross-sections 214 and defect ridge lines 215 of adjacent blocks are continuous without any steps at the joint. The dotted lines in the figure show the outer shape of the block if there were no defect.

[0051] Multiple special blocks are used by stacking them side by side so that the edges of the missing portions of each special block form a series of linear or curved special designs. The missing portion is a component of the shape (e.g., a curved surface) created by intentionally removing a portion from the block, and can also be called a missing portion, a missing shape portion, or a special design forming portion. The special design is, for example, an opening (through hole) or a design shape that appears on the edge of the block assembly (e.g., a wavy edge). [Examples]

[0052] Figure 22 shows an example of a wall designed using design 221, which consists of continuous convex stepped ridges, and special designs 222 and 223, which consist of continuous recessed ridges. Special design 222 is characterized by its ability to drastically alter the external shape of the structural base material, and in this example, the convex stepped side surface of design 221 is smoothly joined to the recessed cross-section of special design 222. In addition, special design 223 has a recessed ridge that forms a closed curve, creating an opening 224 within the wall. Lighting fixtures can be installed in the opening 224. Furthermore, multiple bullet-shaped LED lighting fixture installation holes 226 are formed at equal intervals along the convex ridges on the convex stepped side surface 225 that forms design 221, and bullet-shaped LED lighting fixtures can be installed there. Note that the holes for passing the wiring for the lighting fixtures and bullet-shaped LED lighting fixtures are omitted in the diagram. However, in the blocks where each lighting fixture is installed, you can drill through holes of an appropriate diameter towards unused support holes or beam grooves inside the block and pass the wiring through them.

[0053] Figure 23 shows an embodiment in which, in this embodiment, bullet-shaped LED lighting fixtures are installed in multiple bullet-shaped LED lighting fixture installation holes 226, a gate light is installed in the opening 224 formed by the special design 223, and they are illuminated. Thus, the predetermined design in this disclosure does not refer to a so-called texture (pattern, design), such as the brick-like uneven pattern seen on the surface of the siding panel used in Embodiment 1, but rather to a design that extends over the entire wall surface of a wall, fence, or gate post, such as design 18 and design 221, or a design applied to the external shape, such as special design 222 and special design 223.

[0054] As described above, the block assembly described herein is composed of various shapes of blocks that share a common main body. On the other hand, various functional components such as intercom units or mailboxes need to be installed on walls or gateposts, and dedicated mounting blocks can be manufactured for installing these components. [Examples]

[0055] Figure 24 shows an embodiment of a thick block 241 for lighting installation, which has a lighting space 242 in the middle of the block that penetrates both sides of the block, and a lighting fixture installation workspace 243 at the top of the block. The lighting fixture installation workspace 243 is equipped with lighting fixture mounting screw holes 244 and lighting wiring holes 245, and wiring that has been passed from the bottom of the gatepost or wall can be routed through unused post penetration holes 67 and wiring space 246 to perform the lighting wiring work here.

[0056] Figure 25 shows an embodiment in which a lighting fixture 252 is installed on a thick lighting mounting block 241 via a lighting fixture base 251.

[0057] Figure 26 shows an embodiment of an illuminated message thick block 261 with an illuminated message 262 on its surface. The illuminated message 262 is molded from a transparent or milky white translucent material and penetrates from the surface of the illuminated message thick block 261 to an illuminated message illumination space 263 provided inside the block. By installing a lighting fixture in the illuminated message illumination space 263, light leaks from the illuminated message 262, which is molded from the translucent material, onto the block surface, causing the message to appear. An illuminated message maintenance window 264 is provided on the rear of the block, allowing for work such as wiring and replacement of lighting fixtures. The message "Welcome" in this embodiment is just an example; an address (street number) or name could be displayed to serve as a nameplate. Furthermore, considering the possibility of changes in home ownership, the nameplate portion could be made replaceable.

[0058] Figure 27 shows an embodiment in which an LED message lighting fixture 271 is installed inside an LED message thick block 261. Note that the cover or waterproof cover that covers the LED message maintenance window 264, and the holes for passing wiring, etc., have been omitted.

[0059] Figure 28 shows an embodiment of an intercom sub-unit mounting thick block 281, which has an intercom sub-unit mounting space 282 on the surface of the thick block. The intercom sub-unit mounting space 282 is provided with intercom sub-unit base mounting screw holes 283 and wiring holes 284. Intercom wiring can be passed from the lower part of the gatepost or wall through unused post through holes 67 or beam-enclosed grooves of other blocks, and wiring work can be performed in the intercom sub-unit wiring work space 285 provided inside the block.

[0060] Figure 29 shows an example in which an intercom sub-unit 291 is installed on an intercom sub-unit mounting block 281.

[0061] Figure 30 shows a post-mounting thick block 301, in which the top and rear portions of the block are significantly cut out to allow for the installation of a post. While posts come in various shapes, the block's cutout shape can be modified to match the shape of the post being used. The dotted line in the perspective view indicates the outer shape of the block before the cutout.

[0062] Figure 31 shows an example of a front-in, rear-out type mailbox installed on the surface of a gatepost or wall, with a horizontally elongated opening 312 exposed and a post 311 protruding from the rear.

[0063] Figure 32 shows different wall designs as viewed from the front. This wall is based on the motif of a "wave," and incorporates a sinusoidal curve as design 321, with the amplitude equal to the height of two blocks. The design divides the wall into a main section plane 322 (the shaded area in the figure) and a convex section plane 323 (the area without the shaded area in the figure) at the boundary of design 321.

[0064] Lighting fixture 252 is located on the upper left side of the wall, and an electronic message 262, an intercom unit 291, and a mailbox 311 are located on the upper right side of the wall. Furthermore, a delivery box 324 is placed in an opening the size of six blocks at the lower right side of the wall.

[0065] Figure 33 shows an embodiment of the wall shown in Figure 32. The upper convex surface 323 of the wall is mainly composed of thick blocks with a thickness of, for example, 150 mm, and the lower main body surface 322 is mainly composed of basic blocks with a thickness of, for example, 120 mm. The eight design blocks 331, through which the design 321 (sine curve) passes in the middle of the block, are design blocks in which the thickness changes between 150 mm and 120 mm, with the design 321 acting as a convex stepped ridge. These design blocks 331 can be manufactured in advance at a factory as off-the-shelf parts, but they can also be manufactured to the same dimensions using an industrial 3D printer or a home 3D printer. This makes it possible to provide a gatepost or wall with a higher degree of originality that cannot be achieved with off-the-shelf products.

[0066] In this embodiment, according to the design in Figure 32, a thick block 241 for lighting installation, a thick block 261 for electronic message display, a thick block 281 for intercom unit installation, and a thick block 301 for post installation are installed. Six blocks' worth of openings 332 for a delivery box 324 are provided at the lower right side of the wall. By manufacturing blocks with the same dimensions and specifications using an industrial 3D printer or a home 3D printer, with their height and width adjusted to match the size of the delivery box, it is possible to install a delivery box of any size.

[0067] Figure 33 shows four support columns 333 and three beams 334, but the number, position, and length of the support columns and beams are just examples, and they should be installed appropriately according to the width and height of the wall.

[0068] The block located directly below the opening 332 for the delivery box where the delivery box 324 is installed is provided with a groove inside the upper beam, and the beam 335 fixed to the left and right support columns plays a role in supporting the weight of the delivery box 324.

[0069] Furthermore, by providing grooves on the protruding stepped sides of the eight design blocks 331 that form the design 321, a tape-shaped LED lighting fixture corresponding to the length of the design 321 can be installed.

[0070] Figure 34 is an image showing the wall shown in Figure 33 with an intercom unit 291 and a post 311 installed, as well as a lighting fixture 252, a lighting fixture 271 inside an electronic message thick block 261, and tape-shaped LED lighting fixtures installed in grooves on the sides of the protruding steps forming the design 321, with each LED light illuminated. The soft curved design and gentle indirect lighting create a sense of luxury.

[0071] (Summary of block manufacturing methods) By applying the technology disclosed herein, various structural base materials with different designs can be erected by combining basic blocks, thick blocks, and design blocks or special blocks related to the design. Basic blocks and thick blocks can be produced in a factory as standard parts, and design blocks or special blocks with frequently occurring designs can also be standardized by extracting the design patterns. Some design blocks or special blocks that cannot be standardized can be manufactured using industrial 3D printers or home 3D printers, and overall, gateposts or walls with high aesthetic appeal and originality can be provided at a low cost.

[0072] (Summary regarding design formation) The blocks disclosed herein are design blocks with a stepped design on the block surface, or special blocks with a partially missing design. When these blocks are stacked side by side vertically and horizontally, the design is such that the edges of the protruding stepped portion or the edges of the missing portion are continuous without any steps between adjacent blocks. By arranging them as designed, a predetermined design can be applied to the entire wall surface of a wall, fence, or gatepost, or to the external shape of a wall, fence, or gatepost.

[0073] (Summary of methods for manufacturing block assemblies) The method for manufacturing a block assembly according to this disclosure includes a block creation step and a block connection step.

[0074] The block manufacturing process mainly involves mass-producing basic blocks, thick blocks, and standardized design blocks or special blocks with frequently occurring, general-purpose designs using block manufacturing machines within the factory, and producing some design blocks or special blocks with distinctive designs mainly using industrial 3D printers, home 3D printers, or other block manufacturing machines that are not 3D printers.

[0075] The block connection process is a process in which an operator connects multiple design blocks or special blocks together with a basic block or thick block using a connecting work window, bolt insertion holes, and fastening members such as bolts and nuts, so that a series of designs are formed by convex or missing ridges.

[0076] The blocks of this disclosure can eliminate the joint width required in wet construction methods by using a dry construction method with bolts, making it easy for even inexperienced workers to seamlessly and continuously connect the predetermined design applied by the raised or recessed edges between adjacent blocks without gaps or steps.

[0077] (others) This disclosure is not limited to the embodiments described above. The "design" and "special design" may be, for example, wave-shaped, stair-shaped, mountain-shaped, valley-shaped, letter-shaped, or ring-shaped (for example, circular or polygonal). Furthermore, the protruding step may not be a shape that protrudes perpendicularly to the surface of the main body, but may be a gentle bulge, or protrusions with different protrusion heights such as 10 mm / 20 mm / 30 mm may be combined to form a stair-shaped protrusion.

[0078] The technologies described in each claim can be combined as appropriate, provided they do not conflict technically. Furthermore, some of the technologies of this disclosure can be described as follows:

[0079] (1) The block assembly of the present disclosure is a block assembly that constitutes a wall, fence or gatepost by arranging or stacking a plurality of blocks side by side, wherein each block has a rectangular parallelepiped body portion 22 and a protrusion 23 that is a step protruding from the surface of the body portion, and each of the protrusion edges 25 is composed of a straight line or a curve and does not necessarily have to be the same shape, and the protrusion edges are continuously connected between adjacent blocks so that a predetermined design is formed by the protrusion edges of a plurality of blocks.

In addition to the bolt insertion holes 62, 63, 64, and 65 in the connecting work window 66, the sides of the window in the extended protrusion of the connecting work window 72 have bolt insertion holes 73 that penetrate the left and right sides of the protrusion and bolt insertion holes 74 that penetrate the upper and lower surfaces of the protrusion.

[0084] (6) The main body may have a polygonal (including a circle) post through hole 67 that penetrates from the top surface to the bottom surface of the block, and when stacking multiple blocks, a post or LED lighting wiring can be passed through the post through hole 67 that communicates between adjacent blocks vertically.

[0085] (7) The main body may have a polygonal (including a circle) upper beam-enclosing groove 102 or lower beam-enclosing groove 103 that penetrates from the right side to the left side of the block, and when multiple blocks are placed side by side, the upper beam-enclosing groove 102 or lower beam-enclosing groove 103 that communicates between adjacent blocks on the left and right can be used to pass beams or LED lighting wiring through.

[0086] (8) The main body portion including the protrusion described in (2) above has a cutout portion that extends from the front to the rear of the block, and the edges 215 of the cutout portion are composed of straight lines or curves and do not necessarily have to be the same shape, and the edges of the cutout portions are continuously connected between adjacent blocks so that a predetermined special design is formed by the edges of the cutout portions of multiple blocks.

[0087] (9) The blocks described in (1) to (8) above are fastened together without gaps to adjacent blocks by bolt insertion holes 62, 63, 64, 65, 73, 74, bolts and nuts, which are fastening members, in the connecting work window 66 or 72, respectively, thereby forming a block assembly. [Industrial applicability]

[0088] The technology disclosed herein makes it possible to provide a structural base material for erecting gateposts or walls that are lighter than conventional concrete blocks and have high design and originality at a low cost. This disclosure provides a structural base material for erecting original walls, walls, or gateposts by using blocks made of a lightweight and easily moldable material and creating a continuous design that spans multiple blocks stacked side by side. The majority of the structural base material can be provided at a low cost by using standard blocks produced in a factory, and originality can be enhanced by using some blocks with unique designs manufactured using a 3D printer. In addition, joints can be eliminated by dry construction using bolt fastening, making it easy to install even for inexperienced workers. [Explanation of Symbols]
