Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technology described in Patent Document 1, the stacked stone part is connected to the wire mesh embedded in the backfilling part by a stone connecting metal fitting, so that the integrity between the stacked stone part and the backfilling part can be enhanced. Then, by fixing the stacked stone part and the backfilling part with enhanced integrity to the wall body made of reinforced concrete by an anchor for the wire mesh, their vertical loads are received by the wall body made of reinforced concrete. However, a stone wall structure that can more reliably receive the vertical loads of the stacked stone part and the backfilling part by the wall body made of reinforced concrete is desired.

[0005] In view of this situation, the main problem of the present invention is to provide a stone wall structure that can more reliably receive the vertical loads of the stacked stone part and the backfilling part by the wall body made of reinforced concrete. [Means for solving the problem]

[0006] The first characteristic configuration of the present invention is a stone masonry section formed by stacking stone materials along the wall surface of a reinforced concrete wall structure, A backfill section is formed by filling the space between the stone masonry section and the wall surface with a hardening filler, The wire mesh embedded in the backfill portion, A wire mesh anchor for fixing the wire mesh to the wall surface, A stone wall structure is provided with a stone-pulling metal fitting that connects the aforementioned stone material and the aforementioned wire mesh, The wall structure is integrally provided with a reinforced concrete projection that extends from the wall surface toward the backfill portion.

[0007] In this configuration, the stone masonry section is connected to the wire mesh embedded in the backfill using stone-setting hardware, thereby increasing the unity between the stone masonry section and the backfill. Furthermore, the stone masonry section and backfill, with their increased unity, can be anchored to the reinforced concrete wall structure using wire mesh anchors, and their vertical loads can be reliably supported by the upper surface of the protruding section integrally provided with the wall structure. Therefore, the vertical loads of the stone masonry and backfill sections can be more reliably supported by the reinforced concrete wall structure.

[0008] A second characteristic feature of the present invention is that a number of the aforementioned protrusions are distributed on the wall surface of the wall structure.

[0009] This configuration allows the vertical loads of the stone masonry and backfill sections to be distributed across multiple locations on the wall surface of the wall structure where the protruding sections are distributed. Therefore, it prevents the vertical loads of the stone masonry and backfill sections from concentrating on a single location on the wall surface, allowing the reinforced concrete wall structure to effectively support these vertical loads.

[0010] A third characteristic feature of the present invention is that the protruding portion is positioned at the same height as the beam supporting the wall structure.

[0011] According to this configuration, when transmitting the vertical loads of the masonry and backfill sections received at the protruding parts of the wall structure from the wall structure to the beams, the transmission path within the wall structure can be made as short as possible, resulting in a rational structural form.

[Modes for carrying out the invention]

[0013] An embodiment of the stone wall structure of the present invention will be described with reference to the drawings. As shown in Figures 1 and 2, the stone wall structure 100 is constructed along the wall surface 11A of the wall frame 11 of the structural frame 1 of a building or the like, and comprises a stone masonry section 2 made by stacking stones 21 along the wall surface 11A of the wall frame 11, and a backfill section 3 made by filling the space between the stone masonry section 2 and the wall surface 11A with a hardening filler 31. Furthermore, as shown in Figures 3 and 4, this stone wall structure 100 includes a wire mesh 4 embedded in the backfill 3, wire mesh anchors 5 for fixing the wire mesh 4 to the wall surface 11A, and stone pull fittings 6 for connecting the stone material 21 and the wire mesh 4.

[0014] As shown in Figure 1, the structural frame 1 of the building, etc., comprises a multi-story reinforced concrete column-beam frame 12 consisting of numerous columns supported by a foundation, numerous beams 12A extending between adjacent columns near the floor line (FL) of each floor F, and numerous beams 12B extending between columns at upper and lower intermediate positions on the outer perimeter of each floor F. The structural frame 1 also comprises a floor frame 13 consisting of reinforced concrete floor slabs, etc., which are supported horizontally by the beams 12A of each floor F of the column-beam frame 12, and a wall frame 11 consisting of reinforced concrete walls, etc., which are supported vertically by columns and beams 12A, 12B on the outer perimeter of the column-beam frame 12. In this embodiment, the wall structure 11 is shown as being configured in a downward-spreading inclined position, with the lower part being positioned outward, but it may also be configured in a vertical position or the like.

[0015] As shown in Figure 2, the stone masonry section 2 is constructed by arranging numerous stones 21 horizontally along the wall surface 11A of the wall structure 11 and stacking them vertically. The stones 21 used are relatively large, irregularly shaped natural or artificial stones with different contours and sizes. In the stone masonry section 2, gaps corresponding to joints are formed between adjacent stones 21, and as shown in Figure 1, these gaps are also filled with a hardening filler 31.

[0016] The stone masonry section 2 is positioned on the outer side of the wall structure 11, leaving a space corresponding to the backfill section 3 from the wall surface 11A of the wall structure 11. The backfill section 3 is constructed by filling the entire space between the stone masonry section 2 and the wall surface 11A of the wall structure 11 with a hardening filler 31 without any gaps. Concrete can preferably be used as the hardening filler 31, but mortar or the like can also be used.

[0017] The wire mesh 4 embedded in the backfill section 3 is made of wire mesh (welded wire mesh) formed by welding together metal wires such as stainless steel or iron in a grid pattern, and has numerous horizontal bars (horizontal wires) 41 and numerous vertical bars (vertical wires) 42 that make up a large number of mesh openings. Incidentally, the wire mesh 4 is not limited to wire mesh; it may also be made by assembling a large number of reinforcing bars in a grid pattern.

[0018] The wire mesh 4 is arranged along the wall surface 11A of the wall body 11 and is fixed to the wall surface 11A by a plurality of wire mesh anchors 5 protruding from the wall surface 11A. The plurality of wire mesh anchors 5 are arranged at predetermined intervals in the horizontal and vertical directions of the wall surface 11A. The wire mesh 4 is attached to the plurality of wire mesh anchors 5 in a state of being spaced apart from the wall surface 11A. At least one of the horizontal bars 41 and vertical bars 42 of the wire mesh 4 is joined by welding or the like to the tip side in the protruding direction of the plurality of wire mesh anchors 5. By providing the wire mesh 4 and the wire mesh anchors 5 in this way, the back-up portion 3 is firmly fixed to the wall surface 11A.

[0019] As shown in FIGS. 3 and 4, the stone retaining metal fitting 6 includes a rod-shaped body 61 extending in the thickness direction of the wall body 11, an anchor 62 attached to one end side (outer side) of the rod-shaped body 61, and a hook 63 attached to the other end side (inner side) of the rod-shaped body 61. The stone retaining metal fitting 6 connects the stone material 21 and the wire mesh 4 by embedding and fixing the anchor 62 on one end side in, for example, the upper end portion of the stone material 21 and hooking the hook 63 on the other end side on the horizontal bar 41 or vertical bar 42 of the wire mesh 4. In the present embodiment, the stone retaining metal fitting 6 is provided for each stone material 21, and each of the stone materials 21 is individually connected to the wire mesh 4 by the stone retaining metal fitting 6.

[0020] In the present embodiment, the stone retaining metal fitting 6 is configured such that the distance between the anchor 62 on one end side and the hook 63 on the other end side can be freely changed. Therefore, by changing the distance between the anchor 62 on one end side and the hook 63 on the other end side corresponding to the thickness dimension or the like of the stone material 21, the stone materials 21 having different thicknesses can be appropriately connected to the wire mesh 4 while aligning the surfaces.

[0021] Adding an explanation, in the stone retaining metal fitting 6, at least a predetermined range on one end side and a predetermined range on the other end side of the rod-shaped body 61 are each configured as a bolt shaft portion, and insertion holes through which the bolt shaft portion can be inserted are formed in the anchor 62 and the hook 63. Furthermore, at the bolt shaft portion on one end of the rod-shaped body 61, the anchor 62 is provided so as to be movable in the bolt axis direction, with the bolt shaft portion inserted through the insertion hole of the anchor 62, and a nut 64 for restricting movement is screwed onto the bolt shaft portion at a position on the end side of the anchor 62. Therefore, by screwing the nut 64 onto the bolt shaft at one end of the rod-shaped body 61, the nut 64 can be moved along the bolt axis direction, thereby adjusting the position that restricts the movement of the anchor 62 to one end and changing the distance between the anchor 62 at one end and the hook 63 at the other end.

[0022] Furthermore, at the other end of the rod-shaped body 61, the bolt shaft portion is provided such that the hook 63 can move freely in the bolt axial direction when the bolt shaft portion is inserted through the insertion hole of the hook 63, and a nut 64 for restricting movement is screwed onto the bolt shaft portion at a position on the other end of the hook 63. Therefore, by screwing the nut 64 onto the bolt shaft at the other end of the rod-shaped body 61, the nut 64 can be moved along the bolt axis direction, thereby adjusting the position that restricts the movement of the hook 63 to the other end and changing the distance between the anchor 62 at one end and the hook 63 at the other end. In this way, the distance between the anchor 62 at one end and the hook 63 at the other end can be changed at both the one end and the other end of the rod-shaped body 61.

[0023] As shown in Figures 3 and 4, additional stone anchors 7 can be installed to increase the bonding strength between the stone material 21 and the backfill 3. The stone anchor 7 is constructed, for example, by bending one end (outer side) of a rod-shaped body 71 extending in the thickness direction of the wall structure 11 laterally to form a stone-side anchor portion 72, and bending the other end (inner side) of the rod-shaped body 71 laterally to form a backfill-side anchor portion 73. The stone anchor 7 can be embedded and fixed to the stone-side anchor portion 72 at one end, for example, on the lateral side of the target stone material 21, and the backfill-side anchor portion 73 at the other end, in the backfill 3, thereby increasing the bonding strength between the stone material 21 and the backfill 3.

[0024] Furthermore, in this stone wall structure 100, as shown in Figures 1 and 2, the wall frame 11 of the structural frame 1 is integrally provided with numerous reinforced concrete protrusions 11B that project from the wall surface 11A towards the backfill 3. Therefore, while the stone masonry section 2 and the backfill 3 are fixed to the wall frame 11 via wire mesh anchors 5, their vertical loads can be reliably supported on the upper surface of the protrusions 11B. The following provides a detailed explanation of the specific configuration of the protruding portion 11B, including its shape and arrangement.

[0025] As shown in Figures 1 and 2, in this embodiment, each protrusion 11B is configured as a horizontally elongated rectangle when viewed from the front (see Figure 2), and the upper surface that receives the vertical load of the stone masonry section 2 and the backfill section 3 is configured as a substantially horizontal surface. In addition, the front surface (tip surface) is configured as an inclined surface substantially parallel to the wall surface 11A of the wall structure 11, and the lower surface is configured as a substantially horizontal surface. As shown in Figure 2, the dimensions of each protrusion 11B when viewed from the front are such that, for example, the vertical width H is smaller than the average vertical dimension of the stone material 21 and the beam depth of beams 12A and 12B, and the horizontal width W is smaller than the average horizontal dimension of the stone material 21 (the left-right dimension in the figure). Also, as shown in Figures 3 and 4, the projection dimension D of each protrusion 11B from the wall surface 11A is set to a dimension that exceeds the placement position of the wire mesh 4 and slightly exceeds half the thickness of the backfill 3. The shape and dimensions of each protrusion 11B can be appropriately changed according to the size of the protrusion 11B, the magnitude of the load it will support, and other factors.

[0026] As shown in Figure 2, in this embodiment, the numerous protrusions 11B are distributed on the wall surface 11A of the wall structure 11. For example, the numerous protrusions 11B are arranged in a staggered pattern, with adjacent protrusions 11B in the vertical direction offset from each other in the horizontal direction. In the configuration shown in Figure 2, the numerous protrusions 11B are arranged at predetermined intervals, for example, half a floor (an example of less than one floor) in the vertical direction of the wall structure 11, and at predetermined intervals, for example, more than two protrusions 11B in the horizontal direction of the wall structure 11. Furthermore, the protrusions 11B located near the floor line (FL) of each floor F are arranged in the same position in the horizontal direction, while the protrusions 11B located in the upper and lower intermediate positions of each floor F are arranged in a position that is horizontally offset from the vertically adjacent protrusions 11B.

[0027] Therefore, the vertical loads of the stone masonry section 2 and the backfill section 3 can be distributed to multiple locations on the wall surface 11A of the wall structure 11, where the protruding sections 11B are distributed. Thus, the vertical loads of the stone masonry section 2 and the backfill section 3 are prevented from concentrating on a single location on the wall surface 11A, and the wall structure 11 can suitably receive these vertical loads.

[0028] As shown in Figure 1, in this embodiment, each protrusion 11B is positioned at the same height as the beams 12A and 12B that support the wall structure 11. In this embodiment, the protrusions 11B located near the floor line (FL) of each floor are positioned in a height region corresponding to the upper end portion of the beam 12A that supports the floor structure 13 of each floor F, and are integrally formed with the upper end portion of the beam 12A. Furthermore, the protrusions 11B located at the upper and lower intermediate positions of each floor are positioned in a height region corresponding to substantially the entire beam depth of the beam 12B at the upper and lower intermediate positions of the outer perimeter of each floor, and are integrally formed with substantially the entire beam depth of the beam 12B.

[0029] As shown in Figures 3 and 4, each protruding portion 11B is reinforced with multiple main reinforcements 11a (two in the illustrated example) that extend laterally on the front side (tip side), and multiple shear reinforcements 11b (four in the illustrated example) that extend in the thickness direction of the wall structure 11 and surround the multiple main reinforcements 11a at the tip side (outer side). The base end (inner side) of each shear reinforcement 11b is anchored to beam 12A (see Figure 1) or beam 12B (see Figures 1 and 3) so as to extend beyond the central position in the beam width direction to the inner side (right side in the figures).

[0030] Therefore, when transmitting the vertical loads of the stone masonry section 2 and backfill section 3, which are received at the protruding portion 11B of the wall structure 11, from the wall structure 11 to the beams 12A and 12B, the transmission path within the wall structure 11 can be made as short as possible, resulting in a rational structural form. Furthermore, the arrangement of the numerous protrusions 11B can be appropriately changed depending on the size of the protrusions 11B, the magnitude of the load they support, and other factors.

[0031] [Another embodiment] Other embodiments of the present invention will now be described. Note that the configurations of each embodiment described below are not limited to being applied individually, but can also be applied in combination with the configurations of other embodiments.

[0032] (1) In the above embodiment, the example shown is that the protrusion 11B is positioned at the same height as beam 12A and beam 12B, but the protrusion 11B may be positioned at an appropriate height, such as a different height from beam 12A and beam 12B.

[0033] (2) In the above embodiment, an example was shown in which a large number of protrusions 11B are distributed on the wall surface 11A of the wall structure 11, but the number and arrangement of the protrusions 11B can be changed as needed.

[0034] (3) In the above embodiment, the example shown was that the numerous protrusions 11B were arranged at predetermined intervals of less than one floor in the vertical direction of the wall structure 11, but they may also be arranged at predetermined intervals of one floor or more.
