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, fence or gate sleeve. [Background technology]

[0002] In conventional construction methods, concrete is poured into formwork or concrete blocks are stacked side by side and joined with mortar using wet construction to form a wall-like structural base of appropriate thickness and height, and decorative materials such as tiles or bricks are then attached to the front, back or sides of this with mortar or adhesive to erect a wall, fence or gate sleeve.

[0003] There is also a construction method in which colored mortar or a mortar-like coating made by mixing sand with paint is sprayed or applied with a trowel or roller to the surface of a structural base material, and then walls, fences, or gate sleeves are erected.

[0004] Other dry construction methods that have been devised include a dry construction method in which wall units manufactured in advance at a factory are transported and installed on site, and a dry construction method in which a structural base material manufactured in a factory is erected and exterior tile panels or the like are attached to the surface.

[0005] For example, Patent Document 1 proposes a method of attaching ceramic siding to the surface of a metal skeleton frame using tapping screws and filling the hollow space inside with foamed synthetic resin. Also, Patent Document 2 proposes a construction method in which a panel base material with tile support ribs is integrally molded using foamed resin, and the surface tile is hooked into the support ribs of the panel base material by grooves on the backside of the tile, and then fixed in place using adhesive.

[0006] [Patent Document 1] Patent No. 3091057 [Patent Document 2] Patent No. 3554061 Summary of the Invention [Problem to be solved by the invention]

[0007] However, whether it's the conventional wet method of pouring concrete into formwork, or the wet method of stacking concrete blocks side by side, or the dry method of erecting factory-produced structural bases, the structural bases erected using these methods tend to have a monotonous design based on flatness, and at best, they are limited to a repetition of small irregularities on the surface of the concrete blocks. Therefore, the object of this invention is to provide a block assembly that can be used to form three-dimensional, integrated designs 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 juxtaposing or stacking multiple blocks to form at least a portion of a wall, fence, or gate sleeve. Each block has a connecting hole formed in its side through which a fastening member can be inserted, and the multiple blocks include multiple design blocks or special blocks related to the formation of a design. Each design block has the connecting hole and comprises a rectangular parallelepiped-shaped main body portion, and a protruding portion that protrudes from a portion of the surface of the main body portion and forms a linear or curved ridge line at a position overlapping the surface of the main body portion. The protruding portions may be formed in different shapes. Each main body portion forms a continuous linear or curved design on the surface of the wall, fence, or gate sleeve through one or more of the protruding portion ridge lines, and is connected to the main body portion of an adjacent block by the connecting hole and the fastening member so that the surfaces of the multiple protruding portions are continuous. Furthermore, the special block is a block in which a portion including the main body portion of the block is missing from the front surface to the rear surface, and the ridge line of the missing portion forms a linear or curved ridge line along the outer shape of the block. The recessed ridge lines may be formed in different shapes from each other. Each of the main bodies is connected to the main body of another adjacent block by the connecting holes and the fastening members so that one or more of the recessed ridge lines form a series of straight or curved designs in the outer shape of the wall, fence, or gate sleeve, and the multiple recessed ridge lines are continuous.

[0009] The method for manufacturing a block assembly of the present invention includes a creating step in which a plurality of the blocks are created using a 3D printer or a block manufacturing machine other than a 3D printer, and a connecting step in which an operator connects the plurality of blocks. If the direction perpendicular to the surface of the main body is defined as the front-rear direction, the main body has a window portion recessed or penetrating in the front-rear direction at a position corresponding to the connecting hole, and the connecting hole is a bolt insertion hole that connects the window portion to the outside. In the connecting step, an operator connects the plurality of blocks using the window portion, the bolt insertion hole, and the fastening members, i.e., bolts and nuts, so as to form the design. [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 convex ridgelines and convex surfaces, or on the external shape of the block assembly by multiple missing ridgelines. 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 convex portions. The formation of connecting holes in the main body increases the degree of freedom in designing the shape of the convex portions, and a series of designs are formed by multiple convex ridgelines or missing ridgelines arranged adjacently and continuously. Note that "without gaps" means that there are no joints in wet construction (gaps between blocks that occur when concrete blocks are stacked side by side using mortar as an adhesive).

[0011] According to the manufacturing method of the present invention, blocks other than the design blocks and special blocks involved in forming the design (thin blocks and thick blocks, described below) can be mass-produced in factories as standard components (standard components), and only some of the design blocks and special blocks can be easily and precisely formed using industrial or home 3D printers. Furthermore, by fastening bolts using the windows and connecting holes, the blocks can be easily, reliably, and gap-freely connected to each other. [Brief explanation of the drawings]

[0014] As shown in FIG. 1, a block assembly 11 is a structural base formed by juxtaposing or stacking multiple blocks to form at least a portion of a wall, fence, or gate sleeve. The multiple blocks include one or more design blocks 12. In this embodiment, the multiple blocks that make up the block assembly 11 include multiple design blocks 12, (here, multiple) thin blocks 13, and (here, multiple) thick blocks 14. Hereinafter, an assembly of multiple blocks of the same type will also be referred to as a block section. In addition, in FIGS. 1 to 5, to clarify the explanation of the method for forming the design, connection holes, window sections, post through holes, and beam grooves for connecting each block are omitted; these will be described later.

[0015] FIG. 2 is a schematic diagram illustrating an example of a design block according to the present disclosure. The shape of each design block varies depending on the desired design, but the basic components remain the same. Design block 21 includes a main body 22 and a protruding portion 23. Main body 22 is formed in a rectangular parallelepiped shape, measuring, for example, 400 mm in width, 120 mm in thickness, and 200 mm in height. Protruding portion 23 protrudes from a portion of the surface of main body 22 with a protruding portion height 24 (depth) of, for example, 30 mm, forming a linear or curved protruding ridgeline 25 at a position overlapping the surface of main body 22 when the design block is viewed from the front. In this example, protruding ridgeline 25 (which may simply be referred to as a "ridgeline") forms an S-shaped design consisting of two arc-shaped curves. Between the surface of the main body 22 and the surface of the convex portion 23, a step side surface 26 (which may also be called the "convex portion step side surface") is formed along the convex portion ridge 25, and the step side surface 26 is a band-shaped curved surface whose width is equal to the convex portion height 24 (which may also be called the "convex portion depth").

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

[0017] The thin block 13 is a rectangular parallelepiped block consisting only of the main body 22, without any protrusions 23, and is also called a basic block. The thick block 14 is a rectangular parallelepiped block in which the entire surface of the main body 22 protrudes to 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 being 120 mm thick and the thick block 14 being 150 mm thick.

[0018] FIG. 3 is a front view of the block assembly 11 of FIG. 1. In FIG. 3, the block assembly 11 comprises a thin block section 16 (here) composed of a plurality of thin blocks 13, a thick block section 17 (here) composed of a plurality of thick blocks 14, and a design block section 15 (here) composed of one or more design blocks 12, forming the structural base of the gate sleeve. The surfaces of the thin block section 16 and the surfaces of the continuous main body sections 22 of each block constituting the design block section 15 are smoothly connected without any steps between adjacent blocks to form a main body plane 31 (the unshaded area in the figure, the rear plane). Furthermore, the surfaces of the thick block section 17 and the surfaces of the continuous convex sections 23 of each block constituting the design block section 15 are smoothly connected without any steps between adjacent blocks to form a convex plane 32 (the shaded area in the figure, the front plane).

[0019] (Formation of Design) In this embodiment, the convex ridges 25 of each design block constituting the design block portion 15 form a single, continuous, wavy design 18 from the left end to the right end of the gate sleeve. Adjacent blocks are seamlessly connected using the connecting holes and fastening members described below, resulting in a smooth, step-free connection between the convex step side 26 of each design block and the convex step side 26 of the adjacent design block. This creates a continuous, curved convex step side along the design 18, and the surfaces of the convex portions 23 of multiple (here, all) design blocks are connected in a continuous manner. The convex ridges of multiple blocks may form a multi-step staircase shape, or multiple designs may be formed within a single block assembly. In this way, the convex portions can also be considered design-forming parts. Furthermore, when a thick block and a basic block are adjacent to each other, the edge ridge of the thick block can be part of the design.

[0020] When the block assembly is viewed from the front, the ratio of the area of the convex flat surface to the area of the entire wall surface is between 10% and 90%. This means that the design in this disclosure does not refer to a repeated pattern of small irregularities on the surface (such as a wood grain, stone grain, or brick pattern), but simply refers to a design that extends to the entire structure. In this embodiment, the convex flat surface 32 is the shaded area in FIG. 3, and the main body flat surface 31 is the remaining area. The proportion of the area of the entire wall surface, i.e., the total area of the convex flat surface 32 and the main body flat surface 31, that is, the area occupied by the convex flat surface 32 is approximately 40% to 50%. The main body and the convex portion have a connecting work window 66 or 72, which will be described later, and the area of each connecting work window is included in the area of the main body or convex portion 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 aligned and stacked side by side to form a rectangular shape (4 blocks x 2 rows, 4 blocks x 1 row, and 4 blocks x 3 rows), respectively. However, this rectangular shape is not necessary and 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 ridgeline constituting the design 18 includes a horizontal or vertical straight line, the thin block 13 and the thick block 14 can be aligned side by side or stacked side by side at that straight line (ridgeline), and the resulting step can be used as part of the design 18. Depending on the design, the entire design may be composed entirely of 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 convex portion (including cases where none of the thin blocks 13 or thick blocks 14 are used).

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

[0024] In this embodiment, recesses can be formed on the step side surface 26 corresponding to the ridge line of the protrusion. An LED lighting device can be placed in the recesses. The recesses can be, for example, grooves extending along the ridge line or multiple holes formed along the ridge line.

[0025] Figure 4 shows a portion of a juxtaposed block assembly that includes a continuous design 41. A groove 43 can be provided on the stepped side surface 42 of the convex portion of the design block, spanning the entire length of the continuous design 41. This groove 43 is, for example, 12 mm wide and 6 mm deep, and a long strip-shaped LED lighting fixture can be installed so that it fits into this groove 43.

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

[0027] (Connection structure) In this embodiment, a connecting hole through which a fastening member can be inserted is formed in the side of each block, and adjacent blocks in the block assembly are fastened together by a fastening member that communicates with each other's connecting holes. The fastening member may be, for example, a bolt or a press-fit pin. A window recessed or penetrating in the front-rear direction is formed on the front or back surface of the main body at a position corresponding to the connecting hole. The connecting hole is a bolt insertion hole that connects the window to the outside, and is located so as to communicate with the bolt insertion hole of an adjacent block when the blocks are arranged side by side or stacked. The window is formed in at least one of the four corners of the front surface of the main body that is not covered (exposed) by the protrusion, or at least one of the four corners of the back surface of the main body. A detailed description will be given below using specific examples.

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

[0029] The blocks are arranged side by side or stacked one on top of the other, and bolts and nuts for connecting the blocks are inserted into bolt insertion holes 62, 63, 64, or 65 to perform the tightening operation. To facilitate the insertion of bolts into the bolt insertion holes and the tightening operation with nuts, windows 66 (hereinafter also referred to as "connection work windows") are provided on the front and rear surfaces of the blocks at positions corresponding to the bolt insertion holes. In this example, the opening shape of the connection work windows 66 is triangular, but it may be rectangular or another polygonal shape (including circular). In this example, there are 16 connection work windows 66 in total, eight on each of the front and rear surfaces of the blocks, but the lines in the figure only show a portion of them.

[0030] In this embodiment, at least one of the blocks has a post through-hole 67 that penetrates in the vertical direction. A post member can be placed in the post through-hole 67. Furthermore, if a post through-hole 67 does not have a post member placed in it, this space may be used to place wiring for an LED lighting fixture.

[0031] The post through-holes 67 are holes drilled through the blocks from the top to the bottom, and when erecting a wall, fence, or gate sleeve, posts buried perpendicular to the ground are passed through the post through-holes 67. The posts are, for example, metal square posts measuring 60 mm x 60 mm. In this embodiment, one block has four post through-holes 67 so that when two blocks are stacked one above the other with a shift of half a block, the positions of the post through-holes in the upper and lower blocks will match.

[0032] FIG. 7 shows an example of a thick block. Like the basic block 61, the thick block 71 is manufactured with dimensions of 400 mm wide, 200 mm high, and (in this embodiment) 150 mm thick. The bolt holes 62, 63, 64, 65, and support hole 67 are identical to those of the basic block 61. The thick block 71 has a shape in which the entire front surface of the basic block 61 is extended forward by the height of the protrusion 24 in the design block. The connecting work window 72 on the front surface is deeper than the connecting work window 66 in the basic block 61 by the height of the extended protrusion 24. In the following figures, the bolt holes, connecting work window, and support hole that belong to the main body are denoted by the same reference numerals as in the basic block 61.

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

[0034] Figure 8 shows an example of a design block. Design block 81 is manufactured with the same dimensions as basic block 61, 400 mm wide and 200 mm high. A convex step separates a 120 mm thick section, the same as basic block 61, and a 150 mm thick section, the same as thick block 71. Bolt holes 62, 63, 64, 65, connecting window 66, and support hole 67 are identical to those in basic block 61. The convex section has the same bolt holes 73 and 74 as thick block 71, which are used when connecting to the convex section of an adjacent thick block or design block. The connecting window 66 in the main body is identical to the connecting window 66 in basic block 61, and the connecting window 72 in the convex section is identical to the connecting window 72 in thick block 71.

[0035] Figure 9 shows the basic block, thick block, and design block divided in half widthwise, each 200 mm wide and 200 mm high (for convenience, these are referred to as the "basic half block," "thin half block," "thick half block," and "design half block," respectively). Basic half block 91 is 120 mm thick, thick half block 92 is 150 mm thick, and design half block 93 is a mix of 150 mm and 120 mm thick blocks separated by a convex step. The positions of support 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 basic block 61 when two half blocks are placed side by side. The convex parts of thick half block 92 and design half block 93 have bolt insertion holes 73 and 74, which are the same as those of thick block 71 when two half blocks are placed side by side. In addition, there may be a "special half block" which is a special block divided into two as described below, but it can also be said to be a special block in which more than half of the basic block, thick block, or design block is missing.

[0036] When a wall, fence, or gate sleeve is formed using the basic blocks 61, thick blocks 71, and design blocks 81, or the basic half blocks 91, thick half blocks 92, and design half blocks 93 of this embodiment, as well as the special blocks described below, support posts are embedded vertically in the ground and passed through the support hole 67 of each block. The support posts are installed at intervals of, for example, approximately 1000 mm. However, horizontal beams may be installed between the support posts to reinforce the support posts and to prevent deflection of the blocks connected to the support posts using bolt insertion holes 62, 63, 64, 65, 73, or 74. These beams also serve to support the weight of delivery boxes or other items installed within the wall of the gate sleeve.

[0037] Figure 10 shows an example of a design block 101 with grooves (top-surface groove 102 and bottom-surface groove 103) for containing beams on the upper and lower surfaces of the main body of the design block. In this example, both top-surface groove 102 and bottom-surface groove 103 are provided, but either one is also acceptable. The beam is, for example, a 60mm x 60mm metal rectangular column. The groove measures 60mm wide and 60mm deep to match the size of the beam (with some margin in practice), penetrating the left and right sides of the block. While the figure shows an example of a design block, similar implementations are possible for basic blocks, thick blocks, half blocks, and special blocks. When blocks with top-surface groove 102 or bottom-surface groove 103 are juxtaposed, the grooves are connected between adjacent blocks. The grooves do not necessarily have to be present only in the blocks on the level where the beam is located; they may be present in all blocks. In addition, the space within the groove where no beam member is placed may be used to place the wiring of the LED lighting fixture.

[0038] Figure 11 illustrates the process of arranging a design block 111 and a basic half block 112 side by side. At the joining surface of the two blocks, two connection work windows 66 are used on the front and two on the back of the blocks to insert bolts 113 into the bolt insertion holes 62 or 63 that communicate with each other in the main body, and the bolts are then fastened with nuts 114 in the connection work windows 66 of the opposite block. When the protrusions of the thick blocks or design blocks are juxtaposed adjacent to each other, they are fastened using the bolt insertion holes 73 and connection work windows 72. Note that the figure only shows the two sets of bolts 113 and nuts 114 on the front side.

[0039] Figure 12 illustrates the process of stacking a design block 121 on top of the design block 111 and basic half block 112 fastened together in the previous section. The design block 121 and basic half block 112, which are connected vertically, are fastened together by inserting bolts 113 into the connecting bolt holes 64 and 65 that communicate with each other in the main body, using the connecting work windows 66 located at two positions on the front and two positions on the back of the blocks at the joining surface of the two blocks, and fastening them with nuts 114 in the connecting work windows 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 vertically, are fastened together by inserting bolts 113 into the connecting bolt holes 64 and 65 that communicate with each other in the main body, and the connecting bolt holes 74 that communicate with the protrusions, and fastening them with nuts 114 in the connecting work windows 66 and 72 of the opposite block. In the drawing, only four sets of bolts 113 and nuts 114 on the front side are shown.

[0040] FIG. 13 shows the state after the design block 111, basic half block 112, and design block 121 are fastened together as described above. The convex ridge 131 of the design block 121 and the convex ridge 132 of the design block 111 are continuous without gaps or steps at the joints where the blocks are stacked, forming a continuous design (part of a design). The main body surface of the design block 111, the main body surface of the design block 121, and the surface of the basic half block 112 form a continuous main body plane (rear plane), and similarly, the convex surface of the design block 111 and the convex surface of the design block 121 form a continuous convex plane (front plane). In this manner, in the present disclosure, the juxtaposed stacked blocks are connected to each other without any gaps to form a predetermined design. When stacking concrete blocks side by side using conventional wet construction methods, they had to be glued together using mortar or other materials, and skilled techniques were essential to ensure that the thickness of the adhesive material (joint width) was consistent.However, by joining the blocks with bolts as disclosed in this document, gaps at the joints can be eliminated, making the construction easy for anyone to do.

[0041] 14 to 18 show the assembly process of different embodiments for forming a gate sleeve using the blocks of the present disclosure. Note that, since the method for joining the blocks arranged side by side on the left and the blocks stacked one on top of the other has been described above, some of the figures in this section and thereafter omit the connection work window 66, connection work window 72, bolt insertion hole 62, bolt insertion hole 63, bolt insertion hole 64, bolt insertion hole 65, bolt insertion hole 73, bolt insertion hole 74, and fastening members (bolts 113 and nuts 114) of each block.

[0042] Figure 14 shows an example of the use of support through-hole 67 and underside beam groove 103. Beam 143 is placed horizontally between support 141 and support 142 and fixed to the support using beam fixing bolt 144 and beam fixing bolt 145. Design block 146 with underside beam groove is installed by passing support 141 through support through-hole 67 and placing beam 143 across groove 103. Similarly, basic block 147 with underside beam groove is placed next to design block 146 with underside beam groove and connected with bolts.

[0043] Figure 15 shows the state after the installation work described in the previous section, with the support pillar 142 being passed through the support pillar through-hole 67 of the new basic block 151 with a groove containing a beam within the bottom surface, and is being installed so as to straddle the beam 143. The basic block 151 with a groove containing a beam within the bottom surface is fastened with a bolt to the basic block 147 with a groove containing a beam within the bottom surface. Similarly, the support pillar 141 is passed through the support pillar through-hole 67 of the thick half block 152, and the design block 153 is placed next to it, and the lower design block 146 with a groove containing a beam within the bottom surface or the basic block 147 with a groove containing a beam within the bottom surface are connected to each other with bolts.

[0044] Figure 16 shows the state after the installation work has progressed further from the previous section. Thick half blocks 161, design half blocks 162, etc. are stacked in order, and at the top, thick block with upper surface beam groove 163, thick block with upper surface beam groove 164, and thick block with upper surface beam groove 165 are installed. Finally, beams 166 are fitted into the upper beam groove portions from above, and then fixed to supports 141 and 142 using beam fixing bolts 167 and beam fixing bolts 168.

[0045] This example relates to a structural base for erecting a wall, fence, or gate sleeve, which requires a surface finish to be applied for completion. The structural base constructed in this example has a series of designs 169 (convex ridges) formed by the convex portions of the four design blocks, a portion of the underside of the thick block 165 with a grooved upper beam, and the convex portion of the design half block 162. The convex step divides the structural base into a 120 mm thick main body plane 171 and a 150 mm thick convex plane 172, each of which can be applied with a different surface finish. In this example, the convex plane 172 accounts for just over 50% of the total wall surface area (the sum of the main body plane 171 and convex plane 172 areas).

[0046] Figure 17 shows an example of a surface finish. A wire mesh (lath mesh 173) is installed on the main body plane 171 and the right side of the gate sleeve, forming a base for the coating material known as "lath" or "lath mesh." Siding panels 174, 175, and 176, cut to fit the design 169 (ridge line of the convex portion), are attached to the convex plane 172. A coping 177 can also be installed on top of the structural base material. Since the focus of this disclosure is on the method for constructing the structural base material, the method for fastening components such as the surface finishing material and coping is not described in detail. However, since the structural base material is made of resin, adhesives or tapping screws can be used. Alternatively, when used as a panel base as described in Patent Document 2, tile support protrusion-like components can be fastened to the surface and side of the structural base material disclosed herein.

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

[0048] Figure 19 is a view of the gate sleeve of this example from below. Continuous tape-shaped LED lighting fixture installation grooves 191 are provided along the design 169 on the convex side surfaces of the four design blocks used in this example, a portion of the underside of the thick block 165, and the continuous convex step side surfaces of the design half block 162. Long tape-shaped LED lighting fixtures 192 can be installed in these tape-shaped LED lighting fixture installation grooves 191. Note that although holes for routing the wiring of the tape-shaped LED lighting fixtures are omitted, a through-hole of an appropriate diameter can be drilled in the block at the end of the tape-shaped LED lighting fixture, for example, from the tape-shaped LED lighting fixture installation groove 191 toward an unused support through-hole 67 or a groove within the beam, and the wiring can be routed through the through-hole.

[0049] Figure 20 shows an example in which a long strip-shaped LED lighting fixture 192 is installed in a strip-shaped LED lighting fixture installation groove 191 and turned on. Conventionally, there have been methods for installing LED lighting fixtures, such as attaching a handrail-like part to the underside of a coping or to the wall surface, but these methods tend to have a retrofitting feel and tend to result in a monotonous design. According to the present disclosure, it is possible to erect walls, fences, or gate sleeves with highly original designs, and obtain lighting effects that make the most of those designs.

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

[0051] Multiple special blocks are stacked side by side so that the ridges of the cutouts of each block form a series of straight or curved special designs. The cutouts are components of shapes (e.g., curved surfaces) created by intentionally cutting out blocks, and can also be called cutouts, cutout shapes, or special design parts. Special designs include, for example, openings (through holes) or design shapes that appear on the edges of the block assembly (e.g., wavy edges). [Example]

[0052] FIG. 22 shows an example of a fence designed using design 221 with a continuous convex step ridgeline, and special design 222 and special design 223 with continuous missing ridgelines. Special design 222 features a bold change in the external shape of the structural base material. In this example, the side of the convex step ridge smoothly joins the missing cross section of special design 222 at the end of design 221. Special design 223 also features a closed curved missing ridgeline, forming an opening 224 in the fence. Lighting fixtures can be installed in opening 224. Furthermore, multiple bullet-shaped LED lighting fixture installation holes 226 are formed at equal intervals along the convex step ridgeline on the side of the convex step ridgeline that forms design 221, allowing the installation of bullet-shaped LED lighting fixtures. Although the holes for passing the wiring of the lighting fixtures and bullet-shaped LED lighting fixtures are omitted, in the blocks where each lighting fixture is installed, it is sufficient to drill a through-hole of an appropriate diameter toward an unused post through-hole or beam groove inside the block and pass the wiring through it.

[0053] 23 shows an example in which bullet-shaped LED lighting fixtures are installed in a plurality of bullet-shaped LED lighting fixture installation holes 226, and gate lights are installed in openings 224 formed by special design 223, and the lights are turned on. In this way, the predetermined design in this disclosure does not mean a so-called texture (pattern, design) such as the brick-like uneven pattern seen on the surface of the siding panel used in Example 1, but rather a design that covers the entire wall surface of a wall, fence, or gate sleeve, such as design 18 and design 221, or a design applied to the outer shape, such as special design 222 and special design 223.

[0054] In this way, the block assembly according to the present disclosure is constructed by combining blocks of various shapes that share a common main body. On the other hand, various functional components such as intercom handsets or posts need to be installed on fences or gate sleeves, and dedicated mounting blocks can be manufactured for these installations. [Example]

[0055] Figure 24 shows an example of a thick block 241 for lighting installation, which has a lighting space 242 in the middle of the block that penetrates the front and back of the block, and a space 243 for installing lighting fixtures at the top of the block. The space 243 for installing lighting fixtures has screw holes 244 for installing lighting fixtures and a lighting wiring hole 245, and wiring that has been passed through from the bottom of the gate sleeve or fence can be routed through unused post through-hole 67 and wiring space 246 to install lighting wiring here.

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

[0057] FIG. 26 shows an example of a thick block 261 with an electric message 262 on its surface. The electric message 262 is molded from a transparent or milky white translucent material and penetrates from the surface of the thick block 261 to a space 263 for illuminating the electric message inside the block. By installing a lighting fixture in the space 263 for illuminating the electric message, light from the electric message 262 molded from a translucent material leaks onto the block surface, making the message appear. A window 264 for maintenance of the electric message is provided on the rear of the block, allowing for work such as wiring and replacement of lighting fixtures. Note that the message "Welcome" in this example is merely an example; an address (house number) or a name may also be displayed on the block and used as a nameplate. Furthermore, the nameplate may be designed to be replaceable in consideration of the possibility of a change in the owner of the house.

[0058] 27 shows an embodiment in which an electric message lighting fixture 271 is installed inside a thick electric message block 261. Note that the lid or waterproof cover that covers the electric message maintenance window 264, and the holes for passing wiring through are omitted.

[0059] 28 shows an embodiment of a thick block 281 for mounting an intercom handset, which has an intercom handset mounting space 282 on the surface of the thick block. Intercom handset mounting space 282 is provided with an intercom handset base mounting screw hole 283 and a wiring hole 284. Intercom wiring can be passed from the bottom of the gate sleeve or fence through an unused support post through-hole 67 or groove in the beam of another block, and wiring work can be done in intercom handset wiring work space 285 provided inside the block.

[0060] FIG. 29 shows an embodiment in which an intercom handset 291 is installed on a thick intercom handset mounting block 281.

[0061] Figure 30 shows a post-mounted thick block 301, in which large cutouts have been made in the top and rear surfaces of the block to allow for the installation of posts. There are various shapes of posts, and it is sufficient to manufacture a block with a modified cutout shape to match the shape of the post to be used. The dotted line in the perspective view indicates the external shape of the block before the cutout.

[0062] FIG. 31 shows an embodiment in which a front-loading, rear-exiting type post is installed, in which a horizontally long drop-in opening 312 is exposed on the surface of a gate sleeve or fence and a post 311 protrudes from the rear.

[0063] Figure 32 shows a different fence design example, viewed from the front. This fence has a "wave" motif, incorporating a sine curve with an amplitude the height of two blocks as design 321. Design 321 separates the fence into a main body plane 322 (the shaded area in the figure) and a convex plane 323 (the area without shaded areas in the figure).

[0064] A lighting fixture 252 is placed on the upper left side of the fence, and an electronic message board 262, an intercom handset 291, and a post box 311 are placed on the upper right side of the fence. Furthermore, an opening the size of six blocks is provided at the bottom right side of the fence, and a delivery box 324 is placed there.

[0065] Figure 33 shows an example of the fence shown in Figure 32. The main components are a thick block with a thickness of, for example, 150 mm for the upper convex plane 323 of the fence, and a basic block with a thickness of, for example, 120 mm for the lower main body plane 322. Eight design blocks 331, with design 321 (sine curve) passing through the middle of the block, are design blocks with thicknesses of 150 mm or 120 mm, with design 321 as the convex step ridge. These design blocks 331 can be manufactured in advance in a factory as prefabricated parts, or they can be manufactured to the same dimensional specifications using an industrial 3D printer or a home 3D printer. This allows for the creation of gate sleeves or fences with a higher level of originality that cannot be constructed using prefabricated products.

[0066] In this embodiment, thick block 241 for mounting lighting, thick block 261 for mounting electronic messages, thick block 281 for mounting intercom handset, and thick block 301 for mounting mailbox are installed according to the design in Figure 32, and openings 332 for delivery boxes the size of six blocks are provided at the bottom right side of the fence to install delivery boxes 324. Blocks with modified heights and widths to match the size of the delivery boxes can be manufactured to the same dimensional specifications using an industrial 3D printer or a home 3D printer, allowing delivery boxes of any size to be installed.

[0067] In Figure 33, four pillars 333 and three beams 334 can be seen, but the number, position and length of the pillars and beams are just examples and need to be installed appropriately according to the width and height of the fence.

[0068] The block located directly below the delivery box opening 332 where the delivery box 324 is installed has a groove formed in the upper surface of the beam, and beams 335 fixed to the left and right supports serve to support the weight of the delivery box 324.

[0069] Furthermore, by providing grooves on the stepped side surfaces of the convex portions of the eight design blocks 331 that form the design 321, it is possible to install a strip-shaped LED lighting fixture that corresponds to the length of the design 321.

[0070] Figure 34 shows an image of what it would look like if an intercom handset 291 and a post 311 were installed on the fence shown in Figure 33, and furthermore, lighting fixture 252, lighting fixture 271 inside thick electronic message block 261, and strip-shaped LED lighting fixtures were installed in the grooves on the side of the protruding step that forms design 321, and each LED light was turned on. The soft curved design and gentle indirect light create a sense of luxury.

[0071] (Summary of block manufacturing methods) By applying the technology disclosed herein, structural base materials with a variety of designs can be erected by combining basic blocks, thick blocks, and design blocks or special blocks related to designs. Basic blocks and thick blocks can be produced in factories as standardized parts, and design blocks or special blocks with frequently occurring designs can also be standardized by extracting design patterns. Some design blocks or special blocks that cannot be standardized can be manufactured using an industrial 3D printer or a home 3D printer, making it possible to provide gate sleeves or fences with high design and originality at low cost.

[0072] (Summary of design formation) The blocks disclosed herein are design blocks with designs created by steps on the block surface, or special blocks with designs created by partial defects.When these blocks are stacked side by side, vertically and horizontally, they are designed so that the ridge lines of the raised step parts or the ridge lines of the defective parts between adjacent blocks are continuous without any steps.By arranging these as designed, it is possible to create a predetermined design across the entire wall surface of a wall, fence or gate sleeve, or a predetermined design on the external shape of a wall, fence or gate sleeve.

[0073] (Summary of block assembly manufacturing methods) The method for manufacturing a block assembly according to the present disclosure includes a block forming step and a block connecting step.

[0074] The block production process is a process that mainly uses block production machines in factories to mass-produce basic blocks, thick blocks, and standardized design blocks or special blocks with frequently occurring general designs, and a process that mainly uses industrial 3D printers, home 3D printers, or other block production machines that are not 3D printers to produce some design blocks or special blocks with distinctive designs.

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

[0076] The blocks disclosed herein can be constructed using a dry bolting method, eliminating the joint width required in wet construction methods, making it easy for even unskilled craftsmen to create a continuous design between adjacent blocks with no gaps or steps, using convex or missing ridge lines.

[0077] (others) The present disclosure is not limited to the above-described embodiments. The "design" and "special design" may be, for example, a wave shape, a staircase shape, a mountain shape, a valley shape, a letter shape, or a ring shape (e.g., a circle or a polygon). Furthermore, the protrusion step may not protrude perpendicularly from the surface of the main body, but may be a gentle bulge, or a stepped protrusion may be formed by combining protrusions of different protrusion heights, such as 10 mm, 20 mm, or 30 mm.

[0078] The techniques described in each claim can be combined as appropriate as long as there is no technical contradiction. In addition, part of the techniques of the present disclosure can be described as follows.

[0079] (1) The block assembly of the present disclosure is a block assembly in which a plurality of blocks are arranged side by side or stacked to form a wall, fence, or gate sleeve, and the block has a rectangular parallelepiped main body 22 and a protruding portion 23 formed by a step protruding from the surface of the main body, and each of the protruding ridge lines 25 is composed of a straight line or a curve and does not necessarily have to be the same shape, and the protruding ridge lines of adjacent blocks are continuously connected so that a continuous predetermined design is formed by the protruding ridge lines of the plurality of blocks.

[0080] (2) The convex height 24 forming the convex portion is 10 mm or more, and when multiple blocks are arranged side by side or stacked to form a wall, fence, or gate sleeve, the proportion of the convex plane 32 that is continuous across multiple blocks to the total area of the structure when viewed from the front is 10% or more and 90% or less.

[0081] (3) Grooves 43 or holes 51 are formed on the step side surfaces 26 of the protrusions, and LED lighting fixtures are placed in the grooves 43 or holes 51.

[0082] (4) The main body has polygonal window sections (connection work windows 66) located at the ends of the four corners of the front and rear surfaces of the main body 22, and on the sides of the window sections, bolt insertion holes 62 and 63 that penetrate through the left and right sides of the main body, and bolt insertion holes 64 and 65 that penetrate through the top and bottom surfaces of the main body are formed.

[0083] (5) The convex portion has another window portion (connection work window 72) at a position corresponding to the window portion (connection work window 66) of the main body portion, and the connection work window 72 is deeper than the connection work window 66 by the extended convex portion height 24. In addition to the bolt insertion holes 62, 63, 64, and 65 in the connection work window 66, the side surfaces of the window portion in the extended convex portion of the connection work window 72 are formed with bolt insertion holes 73 that penetrate through the left and right side surfaces of the convex portion, and bolt insertion holes 74 that penetrate through the top and bottom surfaces of the convex portion.

[0084] (6) The main body portion may have a polygonal (including circular) pillar through-hole 67 that penetrates from the top to the bottom of the block, and when stacking multiple blocks, the pillar through-holes 67 that connect adjacent blocks vertically can be used to pass the wiring for pillars or LED lighting.

[0085] (7) The main body can have a polygonal (including circular) upper surface beam groove 102 or lower surface beam groove 103 that penetrates from the right side to the left side of the block, and when multiple blocks are arranged side by side, the upper surface beam groove 102 or lower surface beam groove 103 that connects adjacent blocks on the left and right can be used to pass wiring for beams or LED lighting.

[0086] (8) The main body portion including the convex portion in (2) above has a recessed portion extending from the front surface to the rear surface of the block, and the ridge line 215 of the recessed portion is composed of a straight line or a curve and does not necessarily have to be the same shape. The ridge lines of the recessed portions of multiple blocks are continuously connected between adjacent blocks so that a continuous, specified special design is formed by the ridge lines of the recessed portions of multiple blocks.

[0087] (9) The blocks (1) to (8) above are arranged side by side or stacked in the connecting work window 66 or the connecting work window 72, and fastened to adjacent blocks without gaps using the bolt insertion holes 62, 63, 64, 65, 73, 74, and the fastening members, i.e., bolts and nuts, to form a block assembly. [Industrial Applicability]

[0088] The technology disclosed herein makes it possible to provide inexpensive structural base materials for erecting gate sleeves or fences that are lighter than conventional concrete blocks and have a high level of design and originality. This disclosure uses blocks made of lightweight, highly moldable materials to provide a structural base material for erecting original walls, fences, or gate sleeves, with a continuous design spanning multiple blocks stacked side by side. The majority of the structural base material can be provided inexpensively by using factory-produced standard blocks, while originality can be enhanced by using blocks with unique designs manufactured using a 3D printer for some parts. Furthermore, dry construction using bolts eliminates joints, making construction easy even for unskilled workers. [Explanation of symbols]
