[0001] The present invention relates to a wall structure in which a plurality of block materials are provided inside a frame body.

Background Art

[0002] In a wall structure including a plurality of block materials, the plurality of block materials are arranged side by side in the vertical and horizontal directions inside the frame body. The plurality of block materials are surrounded by the frame body and held inside the frame body. Further, as such a wall structure, conventionally, an upper frame material and a lower frame material are installed between adjacent columns, and a plurality of horizontal members are provided between the upper frame material and the lower frame material and connected to the adjacent columns (see Patent Document 1).

[0003] In the conventional wall structure described in Patent Document 1, a plurality of block materials are arranged side by side between the lower frame material and the horizontal member, between the horizontal members, and between the horizontal member and the upper frame material. However, when constructing the wall structure, in order to stably fix the block materials, an adhesive layer is interposed between the block material and the lower frame material, between the block material and the horizontal member, and between the block material and the upper frame material by applying an adhesive. Therefore, it is necessary to apply an adhesive for each block material and adhere the block materials to the lower frame material, the horizontal member, and the upper frame material one by one, which is troublesome for installing the block materials and constructing the wall structure.

[Modes for carrying out the invention]

[0009] One embodiment of the wall structure of the present invention will be described with reference to the drawings. The wall structure of this embodiment is a structure that constitutes part or all of a wall, and is installed at the installation site together with the wall, or it is installed at the installation site as a standalone wall. In the following, the wall structure of this embodiment will be described using a wall structure that is incorporated into part of a wall as an example.

[0010] Figure 1 is a front view showing a wall 2 including the wall structure 1 of this embodiment, and shows the wall 2 and wall structure 1 installed outdoors. As shown in the figure, wall 2 is a gate wall installed around the gate and includes an intercom 2A, a post 2B, and a wall structure 1. Wall structure 1 is incorporated into the lower part of wall 2 and constitutes a part of wall 2. Wall 2 and wall structure 1 are installed upright on the ground G, which is the installation site, and are self-supporting on the ground G.

[0011] When the wall structure 1 installed at the installation site is viewed from the front, the up-and-down direction is the up-and-down direction R, and the left-and-right direction is the left-and-right direction S. In Figure 1, the up-and-down direction R is the vertical direction, and the left-and-right direction S is the horizontal direction. The thickness direction of the wall structure 1 is the thickness direction of the wall structure 1 installed at the installation site, and is the front-and-back direction when the wall structure 1 installed at the installation site is viewed from the front. In Figure 1, the thickness direction and the left-and-right direction S of the wall structure 1 are mutually orthogonal horizontal directions. Thus, the directions related to the wall structure 1 are specified by the direction in the state when it is installed at the installation site.

[0012] Figure 2 is a perspective view showing the wall structure 1 of this embodiment, with the wall structure 1 extracted from the wall body 2. Figure 3 is a longitudinal section view of the wall structure 1 of this embodiment, viewed from the front, showing the cross-section of the wall structure 1 cut by a plane including the vertical direction R and the left-right direction S. Figure 4 is a longitudinal section view of the wall structure 1 of this embodiment, viewed from the side, showing the cross-section of the wall structure 1 cut by a plane including the vertical direction R and the thickness direction T of the wall structure 1. Figure 5 is a transverse section view of the wall structure 1 of this embodiment, viewed from above, showing the cross-section of the wall structure 1 cut by a plane including the left-right direction S and the thickness direction T of the wall structure 1.

[0013] As shown in the figures, the wall structure 1 comprises a frame 3 and a plurality of block members 4 (shown by dashed lines in Figures 3 to 5) arranged in a row inside the frame 3. The block members 4 are block-shaped wall materials that constitute the wall portion of the wall structure 1, and consist of metal (in this case, aluminum alloy) profiles formed by extrusion molding. The profiles of the block members 4 are formed into a predetermined cross-sectional shape and cut in a direction perpendicular to the longitudinal direction of the profile. This creates a plurality of block members 4 of the same shape. The plurality of block members 4 are arranged in a row in the left-right direction S and the up-down direction R inside the frame 3 and are held inside the frame 3.

[0014] The block material 4 has multiple through holes 4A (voids) and is formed in a rectangular parallelepiped shape. The through holes 4A penetrate the block material 4 in the thickness direction T of the wall structure 1 and are open to both sides in the thickness direction T of the wall structure 1. Both sides in the thickness direction T of the wall structure 1 are one wall side and the other wall side of the wall structure 1. The multiple block materials 4 are arranged side by side inside the frame 3, adjacent to each other in the left-right direction S and the up-down direction R, along the wall surface of the wall structure 1, and are enclosed by the frame 3. Here, three block materials 4 are arranged side by side in the left-right direction S, and four block materials 4 are arranged side by side in the up-down direction R.

[0015] Frame 3 has four frames 10, 20, and 30 (upper frame 10, lower frame 20, and a pair of vertical frames 30) that are combined with each other. The four frames 10, 20, and 30 of frame 3 are hollow frame materials that make up frame 3, and each is made of a metal (in this case, aluminum alloy) profile formed by extrusion molding. The longitudinal direction of the upper frame 10 and the longitudinal direction of the lower frame 20 is the left-right direction S, and the longitudinal direction of the vertical frames 30 is the up-down direction R. In addition, the thickness direction T of the wall structure 1 is the depth direction of frame 3 (upper frame 10, lower frame 20, vertical frames 30).

[0016] The upper frame 10 and lower frame 20 are upper and lower horizontal frames extending in the horizontal direction (left-right direction S), and are positioned between a pair of vertical frames 30. The pair of vertical frames 30 are the left and right side frames of the frame body 3, located on the left and right sides of the frame body 3, and extending in the vertical direction (up-down direction R). The vertical frames 30 are support columns installed on the ground G, and protrude upward from the ground G. The longitudinal ends of the upper frame 10 on both sides are attached to the left and right vertical frames 30, and the longitudinal ends of the lower frame 20 on both sides are attached to the left and right vertical frames 30. In this way, the four frames 10, 20, and 30 of the frame body 3 are framed. The upper frame 10 and lower frame 20 are each erected between the left and right vertical frames 30, extending from one vertical frame 30 to the other.

[0017] The frame 3 surrounds and holds multiple block members 4 with four frames 10, 20, and 30. Inside the frame 3, the block members 4 are arranged on the underside of the upper frame 10, on the upper side of the lower frame 20, and on the sides of the vertical frame 30. The upper frame 10 holds multiple block members 4 arranged in the left-right direction S on the underside of the upper frame 10. The lower frame 20 holds multiple block members 4 arranged in the left-right direction S on the upper side of the lower frame 20. The vertical frame 30 holds multiple block members 4 arranged in the up-down direction R on the sides of the vertical frame 30.

[0018] The wall structure 1 comprises a plurality of horizontal members 40 positioned between each block member 4 arranged in the vertical direction R, and a plurality of vertical members 50 positioned between each block member 4 arranged in the left-right direction S. The horizontal members 40 and vertical members 50 are partition members (horizontal partition members, vertical partition members) that divide the inside of the frame 3, and each is made of a metal (in this case, made of aluminum alloy) profile formed by extrusion molding. The horizontal members 40 extend in the horizontal direction and are positioned between a pair of vertical frames 30 to divide the inside of the frame 3 in the vertical direction R. The vertical members 50 extend in the vertical direction and divide the inside of the frame 3 in the left-right direction S.

[0019] The ends of the horizontal member 40 in the longitudinal direction (left-right direction S) are attached to the left and right vertical frames 30. The horizontal member 40 is installed between the left and right vertical frames 30 and extends from one vertical frame 30 to the other. Multiple horizontal members 40 are located between the upper frame 10 and the lower frame 20, spaced apart from each other in the vertical direction R, and positioned between adjacent block members 4 in the vertical direction R. In addition, horizontal members 40 adjacent to the lower part of the upper frame 10 are positioned at a distance downward from the upper frame 10, and horizontal members 40 adjacent to the upper part of the lower frame 20 are positioned at a distance upward from the lower frame 20. Horizontal members 40 adjacent to each other in the vertical direction R are positioned at a distance in the vertical direction R. The horizontal member 40 is positioned between multiple block members 4 arranged on the lower side and multiple block members 4 arranged on the upper side, holding the upper and lower multiple block members 4.

[0020] The vertical members 50 are installed between adjacent lower frames 20 and horizontal members 40 in the vertical direction R, between adjacent horizontal members 40 in the vertical direction R, and between adjacent horizontal members 40 and the upper frame 10 in the vertical direction R. Between the lower frames 20 and horizontal members 40, between adjacent horizontal members 40, and between horizontal members 40 and the upper frame 10, multiple vertical members 50 are located between the left and right vertical frames 30, spaced apart in the left-right direction S, and positioned between adjacent block members 4 in the left-right direction S. Furthermore, vertical members 50 adjacent to a vertical frame 30 are positioned away from the vertical frame 30 in the left-right direction S, and vertical members 50 adjacent to each other in the left-right direction S are positioned away from each other in the left-right direction S. The vertical members 50 are positioned between block members 4 arranged in the left-right direction S, and hold the left and right block members 4.

[0021] Between the lower frame 20 and the horizontal member 40, the lower end of the vertical member 50 is attached to the lower lower frame 20, and the upper end of the vertical member 50 is fixed to the upper horizontal member 40. In this way, the vertical member 50 is attached to the lower frame 20 and the horizontal member 40, extending from the lower frame 20 to the horizontal member 40. Between the horizontal members 40, the lower end of the vertical member 50 is attached to the lower horizontal member 40, and the upper end of the vertical member 50 is fixed to the upper horizontal member 40. In this way, the vertical member 50 is attached to the upper and lower horizontal members 40, extending from the lower horizontal member 40 to the upper horizontal member 40. Between the horizontal member 40 and the upper frame 10, the lower end of the vertical member 50 is attached to the lower horizontal member 40, and the upper end of the vertical member 50 is fixed to the upper frame 10. As a result, the vertical member 50 is attached to the horizontal member 40 and the upper frame 10, and extends from the horizontal member 40 to the upper frame 10.

[0022] Multiple horizontal members 40 and multiple vertical members 50 are combined in a grid pattern inside the frame 3, dividing the inside of the frame 3 into multiple regions aligned in the left-right direction S and the up-down direction R. The block members 4 are arranged in multiple regions inside the frame 3, aligned along the longitudinal direction of the upper frame 10, the lower frame 20, the horizontal members 40, and the vertical frames 30. Inside the frame 3, the block members 4 are located in the up-down direction R between the lower frame 20 and the horizontal members 40, between the horizontal members 40 and each other, and between the horizontal members 40 and the upper frame 10, and in the left-right direction S between the vertical frames 30 and the vertical members 50 and between the vertical members 50 and each other.

[0023] The left and right vertical frames 30 have grooves 31 that open toward the inside of the frame body 3. The grooves 31 are located in the middle of the vertical frames 30 in the thickness direction T of the wall structure 1 and are formed in a concave shape that is recessed toward the inside of the vertical frames 30. The grooves 31 also extend in the longitudinal direction of the vertical frames 30 and are formed over the entire length of the vertical frames 30. The upper frame 10, the lower frame 20, and the multiple horizontal members 40 are each attached to the grooves 31 of the left and right vertical frames 30 by mounting members 60 to 62.

[0024] The left and right mounting members 60 for the upper frame 10 are fixed to both ends (left and right ends) in the longitudinal direction of the upper frame 10 by fasteners 63, and to the grooves 31 of the vertical frame 30 by fasteners 64. The left and right mounting members 61 for the lower frame 20 are fixed to both ends in the longitudinal direction of the lower frame 20 by fasteners 65, and to the grooves 31 of the vertical frame 30 by fasteners 66. The left and right mounting members 62 for the horizontal members 40 are fixed to both ends in the longitudinal direction of the horizontal members 40 by fasteners 67, and to the grooves 31 of the vertical frame 30 by fasteners 68. Fasteners 63 to 68 are screws.

[0025] The mounting members 60-62 are positioned within the grooves 31 of the vertical frame 30 and housed inside the grooves 31. Each of the upper frame 10, lower frame 20, and multiple horizontal members 40 is attached only within the grooves 31 of the vertical frame 30 by the mounting members 60-62. Inside the frame 3, the block members 4 adjacent to the vertical frame 30 are positioned to cover the grooves 31 of the vertical frame 30, and the mounting members 61, 62 and fasteners 66-68 within the grooves 31. The grooves 31 of the vertical frame 30, and the mounting members 61, 62 and fasteners 66-68 within the grooves 31 are covered and shielded by the block members 4.

[0026] Figure 6 is a magnified vertical cross-sectional view of the portion of Figure 4 including the upper frame 10. Figure 7 is a magnified vertical cross-sectional view of the portion of Figure 4 including the horizontal member 40. Figure 8 is a magnified vertical cross-sectional view of the portion of Figure 4 including the lower frame 20. Figure 9 is a magnified horizontal cross-sectional view of the portion of Figure 5 including one of the vertical frames 30. Figure 10 is a magnified horizontal cross-sectional view of the portion of Figure 5 including the vertical member 50.

[0027] As shown in the figures, the upper frame 10, the lower frame 20, and the left and right vertical frames 30 are formed by processing profiles with the same cross-sectional shape (see Figures 6, 8, and 9). The profiles are extruded profiles formed by extrusion molding of metal (in this case, aluminum alloy) and are formed into a predetermined cross-sectional shape. The cross-sectional shape of the profile is the shape in a cross section perpendicular to the longitudinal direction of the profile. The left and right vertical frames 30 are made of profiles with grooves 31 formed on them. The upper frame 10 has an upper frame body 11 made of a profile with the same cross-sectional shape as the vertical frames 30, and an upper frame cover 12 attached to the upper frame body 11. The lower frame 20 has a lower frame body 21 made of a profile with the same cross-sectional shape as the vertical frames 30, and a lower frame cover 22 attached to the lower frame body 21.

[0028] The upper frame body 11, the lower frame body 21, and the left and right vertical frames 30 are profiles with the same cross-sectional shape having grooves, and are formed in a hollow shape. Therefore, the upper frame body 11 has a groove (upper frame groove 13), and the lower frame body 21 has a groove (lower frame groove 23). The upper frame groove 13 and the lower frame groove 23 correspond to the groove 31, which is the vertical frame groove of the vertical frame 30, and are formed in the same cross-sectional shape as the groove 31. The upper frame cover 12 covers the upper frame groove 13 of the upper frame body 11, and the lower frame cover 22 covers the lower frame groove 23 of the lower frame body 21.

[0029] The upper frame groove 13 is open to the inside and downward of the frame 3 and extends in the longitudinal direction of the upper frame 10. The upper frame cover 12 is fitted into the upper frame groove 13 and mounted on the upper frame groove 13. The upper frame cover 12 extends along the upper frame groove 13 in the longitudinal direction of the upper frame 10 and closes the upper frame groove 13 at the bottom. The lower frame groove 23 is open to the inside and upward of the frame 3 and extends in the longitudinal direction of the lower frame 20. The lower frame cover 22 is fitted into the lower frame groove 23 and mounted on the lower frame groove 23. The lower frame cover 22 extends along the lower frame groove 23 in the longitudinal direction of the lower frame 20 and closes the lower frame groove 23 at the top.

[0030] The upper frame 10 has an opposing portion 14 that faces the block material 4, a pair of holding portions 15 that hold the block material 4, and a plurality of pressing portions 16 that press down on the block material 4 (see Figure 6). The opposing portion 14 is the lower surface of the upper frame body 11, which is the lower surface of the upper frame 10, and the lower surface of the upper frame cover 12. In the vertical direction R, it is positioned above the plurality of block material 4 (the upper surface of the block material 4) located below the upper frame 10, and faces the plurality of block material 4. The pair of holding portions 15 are provided on the upper frame body 11 and are located below the opposing portion 14. The pair of holding portions 15 are formed in parallel to each other, extending in the longitudinal direction of the upper frame 10 between the longitudinal ends of the upper frame 10.

[0031] The pair of retaining parts 15 of the upper frame 10 are projections (retaining pieces) that protrude toward the block material 4, are spaced apart from each other in the thickness direction T of the wall structure 1, and are located on both sides of the wall structure 1 in the thickness direction T relative to the opposing part 14. Furthermore, the pair of retaining parts 15 are located on both sides of the wall structure 1 in the thickness direction T relative to a plurality of adjacent block materials 4 on the lower side of the upper frame 10, and extend along the plurality of block materials 4. In the thickness direction T of the wall structure 1, each of the plurality of block materials 4 is sandwiched between the pair of retaining parts 15 and held between the pair of retaining parts 15.

[0032] Thus, the pair of holding parts 15 of the upper frame 10 are provided on the lower side of the opposing part 14 and are located on both sides of the multiple block members 4 in the thickness direction T of the wall structure 1, with the multiple block members 4 sandwiched between them. The multiple block members 4 are positioned between the pair of holding parts 15 and fit between the pair of holding parts 15. The pair of holding parts 15 hold the multiple block members 4 from both sides in the thickness direction T of the wall structure 1, thereby restricting the movement of the multiple block members 4 in the thickness direction T of the wall structure 1.

[0033] The upper frame 10 presses its pressing portion 16 against the block material 4 located below it, thereby holding the block material 4 in place. The multiple pressing portions 16 of the upper frame 10 are upper frame pressing portions provided on the opposing portion 14 (in this case, the lower surface of the upper frame cover 12), protruding downward from the opposing portion 14 and positioned below it. The pressing portion 16 is also a projection created by a protruding process, where a part of the opposing portion 14 protrudes downward, and is positioned above each of the multiple block material 4 adjacent to the lower side of the upper frame 10. With the upper frame 10 attached to the left and right vertical frames 30, the multiple pressing portions 16 of the upper frame 10 press against each of the multiple block material 4 arranged side by side below the upper frame 10, holding each of the multiple block material 4 downward.

[0034] The lower frame 20 has an opposing portion 24 that faces the block material 4 and a pair of holding portions 25 that hold the block material 4 (see Figure 8). The opposing portion 24 is the upper surface of the lower frame body 21, which is the upper surface of the lower frame 20, and the upper surface of the lower frame cover 22. In the vertical direction R, it is positioned below the multiple block material 4 (the lower surface of the block material 4) located above the lower frame 20, and faces the multiple block material 4. The multiple block material 4 are placed on the opposing portion 24 of the lower frame 20 and come into contact with the opposing portion 24. The pair of holding portions 25 are provided on the lower frame body 21 and are located above the opposing portion 24. The pair of holding portions 25 extend in the longitudinal direction of the lower frame 20 between the longitudinal ends of the lower frame 20 and are formed in parallel to each other.

[0035] The pair of retaining portions 25 of the lower frame 20 are projections (retaining pieces) that protrude toward the block material 4, are spaced apart from each other in the thickness direction T of the wall structure 1, and are located on both sides of the wall structure 1 in the thickness direction T relative to the opposing portion 24. Furthermore, the pair of retaining portions 25 are located on both sides of the wall structure 1 in the thickness direction T relative to a plurality of adjacent block materials 4 on the upper side of the lower frame 20, and extend along the plurality of block materials 4. In the thickness direction T of the wall structure 1, each of the plurality of block materials 4 is sandwiched between the pair of retaining portions 25 and held between the pair of retaining portions 25.

[0036] Thus, the pair of retaining parts 25 of the lower frame 20 are provided on the upper side of the opposing part 24 and are located on both sides of the multiple block members 4 in the thickness direction T of the wall structure 1, with the multiple block members 4 sandwiched between them. The multiple block members 4 are positioned between the pair of retaining parts 25 and fit between the pair of retaining parts 25. The pair of retaining parts 25 hold the multiple block members 4 from both sides in the thickness direction T of the wall structure 1, thereby restricting the movement of the multiple block members 4 in the thickness direction T of the wall structure 1.

[0037] The left and right vertical frames 30 each have an opposing portion 32 that faces the block material 4 and a pair of holding portions 33 that hold the block material 4 (see Figure 9). The opposing portion 32 is the lateral surface of the vertical frame 30 and is located on both sides of the wall structure 1 in the thickness direction T relative to the groove portion 31. The opposing portion 32 is also positioned to the side of the multiple block material 4 (lateral surface of the block material 4) located on the lateral side of the vertical frame 30 in the left-right direction S, and faces the multiple block material 4. The lateral side is the lateral side in the left-right direction S, and the lateral surface is the surface located on the lateral side in the left-right direction S. The multiple block material 4 are in contact with the opposing portion 32 of the vertical frame 30. The pair of holding portions 33 are located on the lateral side of the opposing portion 32 (inside the frame body 3). The pair of holding portions 33 are formed in parallel to each other, extending in the longitudinal direction of the vertical frame 30 between the longitudinal ends of the vertical frame 30.

[0038] The pair of retaining portions 33 of the vertical frame 30 are projections (retaining pieces) that protrude toward the block material 4, are spaced apart from each other in the thickness direction T of the wall structure 1, and are located on both sides of the wall structure 1 in the thickness direction T relative to the opposing portion 32. Furthermore, the pair of retaining portions 33 are located on both sides of the wall structure 1 in the thickness direction T relative to a plurality of adjacent block materials 4 on the lateral side of the vertical frame 30, and extend along the plurality of block materials 4. In the thickness direction T of the wall structure 1, each of the plurality of block materials 4 is sandwiched between the pair of retaining portions 33 and held between the pair of retaining portions 33.

[0039] Thus, the pair of holding parts 33 of the vertical frame 30 are provided on the side of the opposing part 32 and are located on both sides of the multiple block members 4 in the thickness direction T of the wall structure 1, with the multiple block members 4 sandwiched between them. The multiple block members 4 are positioned between the pair of holding parts 33 and fit between the pair of holding parts 33. The pair of holding parts 33 hold the multiple block members 4 from both sides in the thickness direction T of the wall structure 1, thereby restricting the movement of the multiple block members 4 in the thickness direction T of the wall structure 1.

[0040] The horizontal member 40 has an opposing portion 41 that faces the block member 4, two pairs of holding portions 42, 43 that hold the block member 4 (a pair of upper holding portions 42 and a pair of lower holding portions 43 in the vertical direction R), and a plurality of pressing portions 44 that press down on the block member 4 (see Figure 7). The opposing portion 41 is positioned in the vertical direction R below the plurality of block members 4 (the lower surface portion of the block member 4) located above the horizontal member 40, and above the plurality of block members 4 (the upper surface portion of the block member 4) located below the horizontal member 40, and is positioned between the plurality of block members 4 on the upper and lower sides, and faces the plurality of block members 4 on the upper and lower sides. The plurality of block members 4 on the upper side of the horizontal member 40 are placed on the opposing portion 41 of the lower horizontal member 40 and come into contact with the opposing portion 41.

[0041] The upper pair of retaining parts 42 are located above the opposing part 41, and the lower pair of retaining parts 43 are located below the opposing part 41. Each of the pair of retaining parts 42 and 43 extends in the longitudinal direction of the horizontal member 40 between the longitudinal ends of the horizontal member 40 and is formed in parallel with each other. Each of the pair of retaining parts 42 and 43 is a projection (retaining piece) that protrudes toward the block member 4, is spaced apart from each other in the thickness direction T of the wall structure 1, and is located on both sides of the wall structure 1 in the thickness direction T relative to the opposing part 41.

[0042] The upper pair of retaining parts 42 are located on both sides in the thickness direction T of the wall structure 1 with respect to a plurality of adjacent block members 4 on the upper side of the horizontal member 40, and extend along the plurality of block members 4. In the thickness direction T of the wall structure 1, each of the plurality of block members 4 is sandwiched between the pair of retaining parts 42 and held between the pair of retaining parts 42. The lower pair of retaining parts 43 are located on both sides in the thickness direction T of the wall structure 1 with respect to a plurality of adjacent block members 4 on the lower side of the horizontal member 40, and extend along the plurality of block members 4. In the thickness direction T of the wall structure 1, each of the plurality of block members 4 is sandwiched between the pair of retaining parts 43 and held between the pair of retaining parts 43.

[0043] Thus, the pair of holding parts 42 and 43 of the horizontal member 40 are provided on the upper and lower sides of the opposing part 41, respectively. In the thickness direction T of the wall structure 1, each of the pair of holding parts 42 and 43 is located on both sides of the multiple block members 4, with the multiple block members 4 sandwiched between them. The multiple block members 4 are positioned between the pair of holding parts 42 and 43 and fit between them. The pair of holding parts 42 and 43 hold the multiple block members 4 from both sides in the thickness direction T of the wall structure 1, thereby restricting the movement of the multiple block members 4 in the thickness direction T of the wall structure 1.

[0044] The horizontal member 40 presses its pressing portion 44 against the block material 4 located below it, thereby holding down the block material 4. The multiple pressing portions 44 of the horizontal member 40 are horizontal member pressing portions provided on the opposing portion 41, protruding downward from the opposing portion 41 and located below the opposing portion 41. Furthermore, the pressing portion 44 is a projection created by a protruding process, causing a part of the opposing portion 41 to protrude downward, and is located above each of the multiple block material 4 adjacent to the lower side of the horizontal member 40 (see Figure 5). With the horizontal member 40 attached to the left and right vertical frames 30, the multiple pressing portions 44 of the horizontal member 40 are pressed against each of the multiple block material 4 arranged side by side below the horizontal member 40, holding each of the multiple block material 4 downward.

[0045] The vertical member 50 has an opposing portion 51 that faces the block member 4, and two pairs of holding portions 52, 53 (one pair of holding portions 52 and the other pair of holding portions 53 in the left-right direction S) for holding the block member 4 (see Figure 10). The opposing portion 51 is located between the block members 4 (side surfaces of the block members 4) located on both the left and right sides of the vertical member 50 in the left-right direction S, and faces the left and right block members 4. The left and right block members 4 of the vertical member 50 come into contact with the opposing portion 51 of the vertical member 50 between them.

[0046] One pair of retaining parts 52 is located on one side of the opposing part 51, and the other pair of retaining parts 53 is located on the other side of the opposing part 51. Each pair of retaining parts 52 and 53 extends in the longitudinal direction of the vertical member 50 between both ends (lower end and upper end) of the vertical member 50 in the longitudinal direction (up and down direction R) and is formed in parallel with each other. Each pair of retaining parts 52 and 53 is a projection (retaining piece) that protrudes toward the block member 4, is spaced apart from each other in the thickness direction T of the wall structure 1, and is located on both sides of the wall structure 1 in the thickness direction T relative to the opposing part 51.

[0047] One pair of retaining parts 52 are located on both sides of the wall structure 1 in the thickness direction T relative to the adjacent block member 4 on one lateral side of the vertical member 50, and extend along the block member 4. In the thickness direction T of the wall structure 1, the block member 4 is sandwiched between the pair of retaining parts 52 and held between the pair of retaining parts 52. The other pair of retaining parts 53 are located on both sides of the wall structure 1 in the thickness direction T relative to the adjacent block member 4 on the other lateral side of the vertical member 50, and extend along the block member 4. In the thickness direction T of the wall structure 1, the block member 4 is sandwiched between the pair of retaining parts 53 and held between the pair of retaining parts 53.

[0048] Thus, the pair of holding parts 52 and 53 of the vertical member 50 are provided on both sides of the opposing part 51 in the left-right direction S. In the thickness direction T of the wall structure 1, each of the pair of holding parts 52 and 53 is located on both sides of the block member 4, with the block member 4 sandwiched between them. The block member 4 is positioned between the pair of holding parts 52 and 53 and fits between them. The pair of holding parts 52 and 53 hold the block member 4 from both sides in the thickness direction T of the wall structure 1, thereby restricting the movement of the block member 4 in the thickness direction T of the wall structure 1.

[0049] The pairs of holding parts 15, 25, 33, 42, 43, 52, and 53 are positioned along the edges (upper edge, lower edge, one horizontal edge, and the other horizontal edge) of each of the multiple block members 4 on both sides in the thickness direction T of the wall structure 1, and hold each edge of the multiple block members 4. Each block member 4 is held in the top, bottom, left, and right directions by the pairs of holding parts 15, 25, 33, 42, 43, 52, and 53 located at the top, bottom, left, and right, respectively. This ensures that the movement of the block members 4 in the thickness direction T of the wall structure 1 is reliably restricted, and the block members 4 are stably held inside the frame 3.

[0050] Figures 11 to 27 show the construction procedure of the wall structure 1 in this embodiment. Figures 11 to 16, 18 to 20, 22, 23, and 25 to 27 are perspective views of the wall structure 1 under construction, and Figures 17, 21, and 24 are longitudinal cross-sectional views of the wall structure 1 under construction viewed from the side.

[0051] As shown in the diagram, with the upper frame cover 12 not attached to the upper frame body 11 (see Figure 11), the left and right mounting members 60 are fixed to the upper frame 10 with fasteners 63. At this time, a portion of the mounting members 60 is inserted into the upper frame body 11, and the mounting members 60 are fixed inside the upper frame body 11 and the upper frame 10. Also, with the lower frame cover 22 not attached to the lower frame body 21 (see Figure 12), the left and right mounting members 61 are fixed to the lower frame 20 with fasteners 65. At this time, a portion of the mounting members 61 is inserted into the lower frame body 21, and the mounting members 61 are fixed inside the lower frame body 21 and the lower frame 20. Simultaneously, the left and right backing plates 26 are fixed to the lower frame 20 with fasteners 65, and the backing plates 26 are attached to the left and right end faces of the lower frame 20. On each of the multiple horizontal members 40 (see Figure 13), the left and right mounting members 62 are fixed to the horizontal member 40 with fasteners 67.

[0052] Insert the left and right mounting members 61 of the lower frame 20 into the grooves 31 of the left and right vertical frames 30 (see Figure 14), and position the lower frame body 21 of the lower frame 20 between the left and right vertical frames 30. In this state, fix each of the mounting members 61 of the lower frame 20 to the grooves 31 of the vertical frames 30 with the fasteners 66, and attach the lower frame body 21 of the lower frame 20 to the grooves 31 of the left and right vertical frames 30. Next, after attaching the lower frame cover 22 to the lower frame groove 23 (see Figure 15), attach the lower ends of the multiple vertical members 50 to the lower frame 20.

[0053] The vertical member 50 has a pair of locking portions 54 formed at its lower end (see Figures 16 and 17). The pair of locking portions 54 are projections (locking pieces) located on both sides of the vertical member 50 in the thickness direction T of the wall structure 1, and protrude outwards on both sides in the thickness direction T of the wall structure 1. The pair of locking portions 54 of the vertical member 50, located above the lower frame 20, are locked to a pair of holding portions 25 of the lower frame 20, located below the vertical member 50, and are held by the pair of holding portions 25. The pair of locking portions 54 are located below the holding portions 52 and 53 of the vertical member 50, and are positioned below the holding portions 25 of the lower frame 20 (between the holding portion 25 and the opposing portion 24). The pair of locking portions 54 hook onto the pair of holding portions 25 from below and are locked to the pair of holding portions 25. As a result, the lower end of the vertical member 50 is attached to the lower frame 20 and held by the lower frame 20.

[0054] In the vertical member 50 located above the lower frame 20, the pair of locking portions 54 of the vertical member 50 move between a position between the pair of holding portions 25 of the lower frame 20 (unlocked position) and a position where they are locked to the pair of holding portions 25 of the lower frame 20 (locked position), when there is no block member 4 above the lower frame 20. The unlocked position is a position between the pair of holding portions 25 of the lower frame 20 where the pair of locking portions 54 of the vertical member 50 are separated from the pair of holding portions 25 of the lower frame 20 (separated position). In the unlocked position, the pair of locking portions 54 of the vertical member 50 are separated from the pair of holding portions 25 of the lower frame 20 and are not locked to the pair of holding portions 25.

[0055] With the lower end of the vertical member 50 in contact with the lower frame 20 (in this case, the opposing part 24) between the pair of holding parts 25 of the lower frame 20, the vertical member 50 is rotated, causing the pair of locking parts 54 of the vertical member 50 to move between the unlocked position and the locked position. Furthermore, while rotating the vertical member 50, the pair of locking parts 54 of the vertical member 50 are moved from the unlocked position toward the holding part 25 of the lower frame 20. As a result, the pair of locking parts 54 of the vertical member 50 move from the unlocked position toward the locked position and are locked to the pair of holding parts 25 of the lower frame 20.

[0056] The block material 4 is moved downward from above the lower frame 20 toward the lower frame 20 (see Figure 18), and the block material 4 is inserted between the vertical frame 30 and the vertical members 50, and between the vertical members 50 themselves (see Figure 19). Next, the left and right mounting members 62 of the horizontal member 40 are inserted into the grooves 31 of the left and right vertical frames 30, and the horizontal member 40 is positioned between the left and right vertical frames 30. The horizontal member 40 is also positioned on top of the lower block material 4, and the upper ends of the multiple vertical members 50 are fixed to the upper horizontal member 40 with fasteners 69, which are screws. The fasteners 69 penetrate the horizontal member 40 from above and are attached to the opposing parts 51 of the vertical members 50. In this state (see Figure 20), each of the mounting members 62 of the horizontal member 40 is fixed to the grooves 31 of the vertical frame 30 with fasteners 68, and the horizontal member 40 is attached to the grooves 31 of the left and right vertical frames 30.

[0057] As the horizontal member 40 is placed on top of the block members 4 and attached to the left and right vertical frames 30 (see Figure 21), the pressing portion 44 of the horizontal member 40 abuts against each of the block members 4 located below the horizontal member 40 and presses against the block members 4, thereby holding down each of the lower block members 4. The pressing portion 44 of the horizontal member 40 holds down the block members 4 from above and presses them against the lower frame 20 (opposing portion 24) below. This suppresses rattling of the block members 4 located below the horizontal member 40. In addition, the block members 4 are stably positioned between the lower frame 20 and the horizontal member 40.

[0058] Next, the lower ends of the multiple vertical members 50 are attached to the horizontal members 40 (see Figures 22 to 24). A pair of locking parts 54 of the vertical members 50 located above the horizontal members 40 are locked to a pair of holding parts 42 of the horizontal members 40 located below the vertical members 50, and are held by the pair of holding parts 42. Each pair of locking parts 54 is positioned below the holding parts 42 of the horizontal members 40 (between the holding parts 42 and the opposing parts 41). The pair of locking parts 54 hook onto the pair of holding parts 42 from below and are locked to the pair of holding parts 42. As a result, the lower ends of the vertical members 50 are attached to the horizontal members 40 and held by the horizontal members 40.

[0059] On the vertical member 50 located above the horizontal member 40, the pair of locking portions 54 of the vertical member 50 move between a position between the pair of holding portions 42 of the horizontal member 40 (unlocked position) and a position where they are locked to the pair of holding portions 42 of the horizontal member 40 (locked position), when there is no block member 4 above the horizontal member 40. The unlocked position is a position between the pair of holding portions 42 of the horizontal member 40 where the pair of locking portions 54 of the vertical member 50 are separated from the pair of holding portions 42 of the horizontal member 40 (separated position). In the unlocked position, the pair of locking portions 54 of the vertical member 50 are separated from the pair of holding portions 42 of the horizontal member 40 and are not locked to the pair of holding portions 42.

[0060] With the lower end of the vertical member 50 in contact with the horizontal member 40 (in this case, the opposing part 41) between the pair of holding parts 42 of the horizontal member 40, the vertical member 50 is rotated, causing the pair of locking parts 54 of the vertical member 50 to move between the unlocked position and the locked position. Furthermore, while rotating the vertical member 50, the pair of locking parts 54 of the vertical member 50 are moved from the unlocked position toward the holding part 42 of the horizontal member 40. As a result, the pair of locking parts 54 of the vertical member 50 move from the unlocked position toward the locked position and are locked toward the pair of holding parts 42 of the horizontal member 40.

[0061] The block material 4 is moved downward from above the horizontal member 40 toward the horizontal member 40 (see Figure 25), and the block material 4 is inserted between the vertical frame 30 and the vertical member 50, and between the vertical members 50 themselves. Then, the positioning of the horizontal member 40 and fixing of the vertical member 50 (see Figure 19), attachment of the horizontal member 40 (see Figure 20), mounting of the vertical member 50 (see Figure 22), and insertion of the block material 4 (see Figure 25) are repeated until the uppermost block material 4 is inserted. As the horizontal member 40 is positioned on top of the block material 4 and attached to the left and right vertical frames 30, the block material 4 is pressed from above by the pressing portion 44 of the horizontal member 40 and pressed against the lower horizontal member 40 (opposing portion 41). This suppresses rattling of the block material 4 located between the horizontal members 40. In addition, the block material 4 is stably provided between the horizontal members 40.

[0062] Next, the upper frame cover 12 of the upper frame 10 is positioned between the left and right vertical frames 30 (see Figure 26). The upper frame cover 12 is then placed on top of the lower block members 4, and the upper ends of the multiple vertical members 50 are fixed to the upper frame cover 12 using fasteners 69. The fasteners 69 penetrate the upper frame cover 12 from above and are attached to the opposing parts 51 of the vertical members 50. Subsequently, the left and right mounting members 60 of the upper frame 10 are inserted into the grooves 31 of the left and right vertical frames 30, and the upper frame body 11 of the upper frame 10 is positioned between the left and right vertical frames 30. The upper frame body 11 of the upper frame 10 is then moved towards the lower upper frame cover 12, and the upper frame cover 12 is attached to the upper frame groove 13 (see Figure 27). In this state, each of the mounting members 60 of the upper frame 10 is fixed to the grooves 31 of the vertical frame 30 with the fasteners 64, and the upper frame body 11 and the upper frame 10 are attached to the grooves 31 of the left and right vertical frames 30. With this, the construction of the wall structure 1 is completed and the wall structure 1 is finished (see Figure 2).

[0063] As the upper frame 10 is placed on top of the block members 4 and attached to the left and right vertical frames 30 (see Figure 6), the pressing portion 16 of the upper frame 10 abuts against each of the block members 4 located below the upper frame 10 and presses against them, thereby holding down each of the lower block members 4. The pressing portion 16 of the upper frame 10 holds down the block members 4 from above and presses them against the lower horizontal members 40 (opposing portion 41). This suppresses rattling of the block members 4 located below the upper frame 10. In addition, the block members 4 are stably positioned between the upper frame 10 and the horizontal members 40.

[0064] In the wall structure 1 described above, a horizontal member 40 is installed between the left and right vertical frames 30, and the pressing portion 44 of the horizontal member 40 presses down on the block material 4 from above. Therefore, multiple block materials 4 can be easily and stably installed inside the frame 3, improving the constructability of the wall structure 1. It is also possible to reduce the burden of adjusting the block material 4 when installing it inside the frame 3. The pressing portion 16 of the upper frame 10 allows multiple block materials 4 located below the upper frame 10 to be easily and stably installed inside the frame 3. By holding the block material 4 between a pair of holding portions 15, 25, 33, 42, 43, 52, 53, the movement of the block material 4 can be easily restricted, and the block material 4 can be stabilized.

[0065] The pair of locking portions 54 of the vertical member 50 are locked to the pair of holding portions 25 of the lower frame 20 and the pair of holding portions 42 of the horizontal member 40, respectively. Therefore, the pair of holding portions 25 of the lower frame 20 and the pair of holding portions 42 of the horizontal member 40 can hold the vertical member 50 in addition to the block member 4. By moving the pair of locking portions 54 of the vertical member 50 between the pair of holding portions 25 of the lower frame 20 and between the pair of holding portions 42 of the horizontal member 40, the pair of locking portions 54 of the vertical member 50 can be easily locked to the pair of holding portions 25 of the lower frame 20 and the pair of holding portions 42 of the horizontal member 40, respectively.

[0066] The upper frame 10, lower frame 20, and horizontal member 40 are each attached to a common groove 31 of the vertical frame 30. This suppresses the exposure of the areas where the upper frame 10, lower frame 20, and horizontal member 40 are attached to the vertical frame 30, thereby improving the aesthetic appearance of the wall structure 1. Furthermore, the left and right vertical frames 30, the upper frame body 11 of the upper frame 10, and the lower frame body 21 of the lower frame 20 can be manufactured from profiles with the same cross-sectional shape, thereby reducing the manufacturing cost of the left and right vertical frames 30, the upper frame body 11 of the upper frame 10, and the lower frame body 21 of the lower frame 20.

[0067] Figure 28 is a perspective view showing the retaining portion 44 of the horizontal member 40 in another embodiment. Figure 29 is a longitudinal cross-sectional view showing the state in which the block material 4 is held down by the retaining portion 16 of the upper frame 10 in another embodiment. Figure 30 is a longitudinal cross-sectional view showing the state in which the block material 4 is held down by the retaining portion 44 of the horizontal member 40 in another embodiment. As shown in the figure, the retaining portion 44 of the horizontal member 40 and the retaining portion 16 of the upper frame 10 are made of an elastic material that can be elastically deformed, and in this case, they are made of a sponge (for example, a silicone sponge, which is a sponge-like silicone rubber). The retaining portion 44 of the horizontal member 40 is attached to the opposing portion 41 of the horizontal member 40 and extends in the longitudinal direction of the horizontal member 40. The retaining portion 16 of the upper frame 10 is attached to the opposing portion 14 of the upper frame 10 and extends in the longitudinal direction of the upper frame 10.

[0068] The pressing portion 44 of the horizontal member 40 is pressed against the block member 4 located below the horizontal member 40 and undergoes elastic deformation. The horizontal member 40 holds down multiple block members 4 with one pressing portion 44. The pressing portion 16 of the upper frame 10 is pressed against the block member 4 located below the upper frame 10 and undergoes elastic deformation. The upper frame 10 holds down multiple block members 4 with one pressing portion 16. Thus, the pressing portion 44 of the horizontal member 40 may be attached to the horizontal member 40 by adhesive or the like, and the pressing portion 16 of the upper frame 10 may be attached to the upper frame 10 by adhesive or the like.

[0069] Furthermore, the upper frame body 11 of the upper frame 10 may be formed from an outline without the upper frame groove 13, and the lower frame body 21 of the lower frame 20 may be formed from an outline without the lower frame groove 23. In this case, the upper frame 10 does not have an upper frame cover 12, and the upper frame body 11 becomes the upper frame 10. Similarly, the lower frame 20 does not have a lower frame cover 22, and the lower frame body 21 becomes the lower frame 20. The left and right vertical frames 30 may be attached to support columns, and the left and right vertical frames 30 may be supported by the support columns. The present invention is not limited to gate walls and is applicable to various wall structures. The wall structure may be a wall structure installed independently as a wall body, or it may be a wall structure provided as part of a wall body.

[0070] As described above, this embodiment discloses the wall structures described in (1) to (7) below.

[0071] (1) A wall structure in which a plurality of block members are arranged in the left-right and up-down directions inside a frame body having an upper frame, a lower frame, and left and right vertical frames, A horizontal member is installed between the left and right vertical frames and positioned between the block members arranged in the vertical direction, The system comprises vertical members that are installed between the lower frame and the horizontal members, between the horizontal members themselves, and between the horizontal members and the upper frame, and are positioned between the block members that are arranged in the left-right direction. The horizontal member is a wall structure having a pressing portion that presses against the block material located below the horizontal member to hold the block material in place. In the wall structure described in (1), multiple block materials can be easily and stably installed inside the frame, thereby improving the constructability of the wall structure.

[0072] (2) In the wall structure described in (1), The upper frame is a wall structure having a pressing portion that presses against the block material located below the upper frame to hold the block material in place. In the wall structure described in (2), multiple block members located below the upper frame can be easily and stably installed inside the frame.

[0073] (3) In the wall structure described in (1) or (2), Each of the upper frame, lower frame, left and right vertical frames, horizontal members, and vertical members has a pair of retaining parts that are located on both sides of the wall structure in the thickness direction relative to the block material and extend along the block material. The block material is sandwiched between the pair of holding parts, forming a wall structure held between the pair of holding parts. In the wall structure described in (3), the block material can be stabilized by holding it between a pair of retaining parts, thereby easily restricting the movement of the block material.

[0074] (4) In the wall structure described in (3), The vertical member has a pair of locking portions located on both sides in the thickness direction of the wall structure, The pair of locking portions of the vertical member located above the lower frame are locked to the pair of holding portions of the lower frame. The pair of locking portions of the vertical member, located above the horizontal member, are locked to the pair of holding portions of the horizontal member, forming a wall structure. In the wall structure described in (4), the vertical members can be held in addition to the block members by the pair of retaining parts of the lower frame and the pair of retaining parts of the horizontal members.

[0075] (5) In the wall structure described in (4), The pair of locking portions of the vertical member located on the upper side of the lower frame move between a position between the pair of holding portions of the lower frame and a position where they are locked to the pair of holding portions of the lower frame, when the block member is not located on the upper side of the lower frame. The pair of locking portions of the vertical member, located above the horizontal member, move between a position between the pair of holding portions of the horizontal member and a position where they are locked to the pair of holding portions of the horizontal member, when there is no block member above the horizontal member. In the wall structure described in (5), the pair of locking parts of the vertical members can be easily locked to the pair of holding parts of the lower frame and the pair of holding parts of the horizontal members by moving the pair of locking parts of the vertical members between the pair of holding parts of the lower frame and the pair of holding parts of the horizontal members, respectively.

[0076] (6) In a wall structure described in any of (1) through (5), The left and right vertical frames are a wall structure having grooves that open toward the inside of the frame and extend in the longitudinal direction of the vertical frames, to which the upper frame, the lower frame, and the horizontal members are attached. In the wall structure described in (6), the exposure of the upper frame, lower frame, and horizontal members where they are attached to the vertical frame can be suppressed, thereby improving the aesthetic appearance of the wall structure.

[0077] (7) In the wall structure described in (6), The left and right vertical frames are made of a profile in which the groove portion is formed. The upper frame is made of a profile with the same cross-sectional shape as the vertical frame profile, and comprises an upper frame body with a groove formed therein, and an upper frame cover that covers the groove of the upper frame body. The lower frame is a wall structure comprising a lower frame body having a groove formed therein, and a lower frame cover covering the groove of the lower frame body, with the lower frame being made of a profile having the same cross-sectional shape as the profile of the vertical frame. In the wall structure described in (7), the left and right vertical frames, the upper frame body of the upper frame, and the lower frame body of the lower frame can be manufactured from profiles of the same cross-sectional shape, thereby reducing the manufacturing costs of the left and right vertical frames, the upper frame body of the upper frame, and the lower frame body of the lower frame.

Claims

1. A wall structure in which multiple block members are arranged in the left-right and up-down directions inside a frame having an upper frame, a lower frame, and left and right vertical frames, A horizontal member is installed between the left and right vertical frames and positioned between the block members arranged in the vertical direction, The system comprises vertical members that are installed between the lower frame and the horizontal members, between the horizontal members themselves, and between the horizontal members and the upper frame, and are positioned between the block members that are arranged in the left-right direction. The horizontal member has a pressing portion that presses against the block member located below the horizontal member to hold the block member in place. Each of the upper frame, lower frame, left and right vertical frames, horizontal members, and vertical members has a pair of retaining parts that are located on both sides of the wall structure in the thickness direction relative to the block material and extend along the block material. The block material is sandwiched between the pair of holding parts and held between the pair of holding parts, The vertical member has a pair of locking portions located on both sides in the thickness direction of the wall structure, The pair of locking portions of the vertical member located above the lower frame are locked to the pair of holding portions of the lower frame. The pair of locking portions of the vertical member, located above the horizontal member, are locked to the pair of holding portions of the horizontal member, forming a wall structure.

2. In the wall structure described in claim 1, The upper frame is a wall structure having a pressing portion that presses against the block material located below the upper frame to hold the block material in place.

3. In the wall structure described in claim 1 or 2, The pair of locking portions of the vertical member located on the upper side of the lower frame move between a position between the pair of holding portions of the lower frame and a position where they are locked to the pair of holding portions of the lower frame, when the block member is not located on the upper side of the lower frame. The pair of locking portions of the vertical member, located above the horizontal member, move between a position between the pair of holding portions of the horizontal member and a position where they are locked to the pair of holding portions of the horizontal member, when there is no block member above the horizontal member.

4. In the wall structure described in claim 1 or 2, The left and right vertical frames are a wall structure having grooves that open toward the inside of the frame and extend in the longitudinal direction of the vertical frames, to which the upper frame, the lower frame, and the horizontal members are attached.

5. In the wall structure described in claim 4, The left and right vertical frames are made of a profile in which the groove portion is formed. The upper frame is made of a profile with the same cross-sectional shape as the vertical frame profile, and comprises an upper frame body with a groove formed therein, and an upper frame cover that covers the groove of the upper frame body. The lower frame is a wall structure comprising a lower frame body having a groove formed therein, and a lower frame cover covering the groove of the lower frame body, with the lower frame being made of a profile having the same cross-sectional shape as the profile of the vertical frame.
