Description

[Technical Field]

[0001] The present invention relates to a wet random laying structure of irregular stone materials and a wet random laying construction method for irregular stone materials. [Background technology]

[0002] A wet stone cladding method is known in which multiple stones (hereinafter referred to as "predefined stones") formed into a predetermined shape and size are attached to the wall surface via a backfill material such as mortar (see, for example, Patent Documents 1 and 2).

[0003] In this type of wet stone cladding method, multiple horizontally extending rebars are attached to the wall surface at a specified interval (pitch) in the vertical direction, and stone trigger hardware attached to the standard stone is hooked onto these rebars. This prevents the standard stone from peeling off from the wall surface. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-252243 [Patent Document 2] Japanese Patent Application Publication No. 63-247465 Summary of the Invention [Problem to be solved by the invention]

[0005] In the wet stone laying method, the vertical pitch of the multiple reinforcing bars is set according to the height of the standard stone. Therefore, when irregular stone materials of different shapes and sizes (hereinafter referred to as "irregular stone materials") are randomly laid on the wall surface using the wet stone laying method, there is a possibility that there are no reinforcing bars around the standard stone materials to which stone trigger hardware can be attached.

[0006] One possible solution to this problem is to narrow the pitch of the rebars, but this would increase the number of rebars required, which would make it more time-consuming to attach the rebars to the wall surface and potentially reduce workability.

[0007] In consideration of the above, the present invention aims to improve workability while suppressing the peeling of irregular stone materials from the wall surface. [Means for solving the problem]

[0008] According to the first aspect The wet random laying structure of irregular stone comprises a base mesh attached to the wall surface, a plurality of irregular stone materials attached to the wall surface on top of the base mesh via backfill material, and stone pull hardware attached to the irregular stone materials and hooked onto the base mesh.

[0009] First aspect According to the wet random laying structure of irregular stone materials, a base mesh is attached to the wall surface. A plurality of irregular stone materials are attached to the wall surface on top of this base mesh via backfill material. In addition, stone puller hardware attached to the irregular stone materials is hooked onto the base mesh. This stone puller hardware prevents the irregular stone materials from peeling off from the wall surface.

[0010] Furthermore, by attaching a fine mesh base mesh to the wall surface, stone trigger hardware can be easily attached to the base mesh even for irregular shaped stones.

[0011] Furthermore, since the base mesh of the present invention is planar, the number of attachment points to the wall surface is reduced compared to the conventional wet stone veneer method, which involves driving anchors at intervals between the rebars to attach them to the wall surface, thereby improving the workability of the base mesh.

[0012] In this way, the present invention can improve workability while suppressing the peeling of irregular stone materials from the wall surface.

[0013] According to the second aspect The wet random laying structure of irregular stone is According to the first aspect In a wet randomly laid structure of irregular stone materials, a plurality of anchors are provided protruding from the wall surface, and the base mesh is attached to the plurality of anchors with a gap between them and the wall surface.

[0014] Second aspect According to the wet random laying structure of irregular stone materials, the base mesh is attached to a plurality of anchors protruding from the wall surface with a gap between them.

[0015] By providing a gap between the base mesh and the wall surface in this way, it becomes easier to hook stone trigger hardware onto the base mesh, thereby improving workability.

[0016] In addition, by leaving a gap between the base mesh and the wall surface, the base mesh is placed in the center of the thickness of the backfill material for the irregular stone, which suppresses cracking of the backfill material, improves the adhesion of the irregular stone, and prevents efflorescence, which is likely to occur in wet areas such as large baths and outdoor areas exposed to rain.

[0017] Furthermore, in conventional wet stone cladding methods, each rebar is attached to an anchor that protrudes from the wall surface. Therefore, narrowing the vertical pitch of the rebars increases the number of anchors required, which increases the effort required to attach the anchors to the wall surface.

[0018] In contrast, the base mesh of the present invention is planar, so compared to the conventional wet stone veneer method of attaching flow-through rebars to the wall surface by driving anchors at intervals between the flow-through rebars, the number of anchors required to be installed on the wall surface can be reduced, thereby further improving workability.

[0019] According to the third aspectIn the wet random laying method for irregular stone materials, irregular stone materials are attached to the wall surface via backfill material on top of a base mesh attached to the wall surface, and stone trigger hardware attached to the irregular stone materials is hooked onto the base mesh.

[0020] Third aspect According to the wet random laying method for irregular stone materials, the irregular stone materials are attached to the wall surface via backfill material on top of a base mesh attached to the wall surface, and stone trigger hardware attached to the irregular stone materials is hooked onto the base mesh.

[0021] In this case, by attaching a fine mesh base mesh to the wall surface, stone trigger hardware can be easily attached to the base mesh even if the stone is irregular in shape.

[0022] Furthermore, since the base mesh of the present invention is planar, the number of attachment points to the wall surface is reduced compared to the conventional wet stone veneer method, which involves driving anchors at intervals between the rebars to attach them to the wall surface, thereby improving the workability of the base mesh.

[0023] In this way, the present invention can improve workability while suppressing the peeling of irregular stone materials from the wall surface. [Effects of the Invention]

[0024] As described above, according to the present invention, it is possible to improve workability while suppressing the peeling of irregular stone materials from the wall surface. [Brief explanation of the drawings]

[0026] Hereinafter, with reference to the drawings, a wet random laying structure and a wet random laying method for irregular shaped stone materials according to one embodiment will be described.

[0027] (irregular stone) 1 shows a plurality of irregular stones 20 randomly laid on a wall surface 10S of a wall 10 using a wet random laying structure according to this embodiment. The plurality of irregular stones 20 are irregularly shaped (randomly shaped) stones with different shapes and sizes. These irregular stones 20 are, for example, natural stone or artificial stone.

[0028] (Base mesh) A plurality of irregular stones 20 are attached to the wall surface 10S of the wall 10 via backfill material 50 on top of a base mesh 30. The base mesh 30 is a wire mesh made of metal such as stainless steel or iron. The base mesh 30 also has a plurality of vertical reinforcement bars 30A and horizontal reinforcement bars 30B that are pre-joined (welded) in a lattice pattern. The mesh size R of the base mesh 30 is smaller than that of the irregular stones 20.

[0029] The base mesh 30 is arranged along the wall surface 10S of the wall 10 and is attached to a plurality of anchors 12 protruding from the wall surface 10S of the wall 10. The anchors 12 are arranged at intervals in the height and width directions of the wall 10. Furthermore, a plurality of meshes R of the base mesh 30 are arranged between adjacent anchors 12.

[0030] 2, the base mesh 30 is attached to a plurality of anchors 12 at intervals from the wall surface 10S of the wall 10. The plurality of anchors 12 are, for example, post-installed anchors that are driven into the wall surface 10S of the wall 10. At least one of the vertical reinforcement 30A and the horizontal reinforcement 30B of the base mesh 30 is joined to the tip end of the protruding direction of these anchors 12 by welding or the like.

[0031] The lower part of the base mesh 30 is attached to a plurality of anchors 42 that protrude upward from the floor 40. The plurality of anchors 42 are post-installed anchors that are driven into the floor 40. The plurality of anchors 42 are also arranged at intervals in the width direction of the wall 10. At least one of the vertical reinforcement 30A and the horizontal reinforcement 30B of the base mesh 30 is joined to the tip side (upper end side) of these anchors 42 in the protruding direction by welding or the like.

[0032] The base mesh 30 may be a standard product or a custom-made product.

[0033] Wall 10 is made of reinforced concrete and rises from floor 40. This wall 10 is, for example, the wall of a bathroom (large communal bath), and the lower part of wall surface 10S is waterproofed by waterproof layer 14. For this reason, anchor 42 in this embodiment is provided on floor 40, not on the lower part of wall 10. However, it is also possible to provide anchors similar to anchor 12 on the lower part of wall 10 and attach base mesh 30 to these anchors.

[0034] In this embodiment, the wall 10 is a bathroom wall, but the wall 10 is not limited to a bathroom wall and may be any other wall. Furthermore, the wall 10 is not limited to a wet wall such as a reinforced concrete wall, but may be a dry wall.

[0035] (Backfill material) The plurality of irregular stones 20 are attached to the wall surface 10S of the wall 10 via a backfill material 50 on top of a base mesh 30. The backfill material 50 is, for example, mortar, grout, or cement paste.

[0036] The backfilling material 50 is filled into each mesh R of the base mesh 30, and is also filled (painted) between the back surface 20A of each irregular stone 20 and the base mesh 30. In other words, the backfilling material 50 is filled (painted) without gaps between the multiple irregular stones 20 and the wall surface 10S of the wall 10. The backfilling material 50 is also filled into the joints M between adjacent irregular stones 20.

[0037] In addition, admixture may be added to the backfilling material 50 as needed.

[0038] (Stone pull hardware) Each of the irregular stones 20 is provided with a stone puller 22. The stone puller 22 is a wire rod made of metal such as stainless steel or iron. The stone puller 22 is provided, for example, on the upper end 20U of the irregular stone 20.

[0039] 3, an attachment hole 24 is formed in the upper end 20U of the irregular stone 20. One end of the stone puller hardware 22 is inserted into this attachment hole 24, and the stone puller hardware 22 is fixed to the upper end of the irregular stone 20 by filling it with a filler such as an adhesive.

[0040] The other end of the stone pulling hardware 22 is bent into a hook shape and hooked onto the vertical reinforcement 30A, horizontal reinforcement 30B, or the intersection of the vertical reinforcement 30A and horizontal reinforcement 30B of the base mesh 30. This prevents the irregular stone 20 from peeling off from the wall surface 10S of the wall 10, for example, during an earthquake. In addition, two stone pulling hardware 22 are provided on the irregular stone 20. This further prevents the irregular stone 20 from peeling off from the wall surface 10S of the wall 10, for example, during an earthquake.

[0041] In this embodiment, the horizontal reinforcement 30B of the base mesh 30 is arranged on top of the vertical reinforcement 30A. In other words, the vertical reinforcement 30A is arranged between the horizontal reinforcement 30B and the wall surface 10S of the wall 10. This makes it easier to hook the stone-pulling hardware 22 onto the horizontal reinforcement 30B than onto the vertical reinforcement 30A.

[0042] In addition, at least one stone puller 22 can be provided on the irregular stone 20. The stone puller 22 is not limited to being provided on the top end of the irregular stone 20, but may also be provided on the side end of the irregular stone 20, for example.

[0043] (Wet random laying method using irregular shaped stone) Next, an example of a wet random laying method for irregular stone materials according to this embodiment will be described.

[0044] 3, first, a plurality of anchors 12 are driven into the wall surface 10S of the wall 10, and a plurality of anchors 42 are driven into the upper surface of the floor 40. Next, the base mesh 30 is attached to the plurality of anchors 12, 42 with a gap between them and the wall surface 10S of the wall 10.

[0045] More specifically, the vertical reinforcement 30A, the horizontal reinforcement 30B, or the intersections of the vertical reinforcement 30A and the horizontal reinforcement 30B of the base mesh 30 are joined by welding or the like to the tip ends of the protruding direction of the multiple anchors 12. Also, the vertical reinforcement 30A and the horizontal reinforcement 30B at the bottom of the base mesh 30 are joined to the multiple anchors 42 by welding or the like. Note that, from the viewpoint of joining strength, it is desirable to join the intersections of the vertical reinforcement 30A and the horizontal reinforcement 30B of the base mesh 30 to the anchors 12.

[0046] Next, the backfill material 50 is applied to the wall surface 10S of the wall 10 with a trowel or the like from above the base mesh 30 without gaps and with a substantially uniform thickness. It is desirable to apply an adhesion enhancer to the wall surface 10S of the wall 10 in advance.

[0047] Next, the irregular stone 20 is temporarily placed on the base mesh 30, and the spacing (joint M) between adjacent irregular stone 20 is adjusted. At this time, the shape (outer shape) of the irregular stone 20 is adjusted as necessary using a power tool or a hammer.

[0048] Next, the irregular stone 20 is removed from the wall surface 10S of the wall 10, and a stone pulling hardware 22 is attached to the irregular stone 20. Specifically, a mounting hole 24 is formed in the upper end 20U of the irregular stone 20 using an electric drill or the like (not shown). Then, with one end of the stone pulling hardware 22 inserted into the mounting hole 24, a filler such as adhesive is filled in. By repeating this procedure, multiple stone pulling hardware 22 are attached to the irregular stone 20.

[0049] Next, the backfill material 50 is applied to the back surface 20A of the irregular stone 20, and the back surface 20A of the irregular stone 20 is attached to a predetermined position on the base mesh 30, as shown in Figure 4. At this time, the irregular stone 20 is attached to the wall surface 10S of the wall 10 without any gaps by hitting the irregular stone 20 with a hammer or the like. In addition, the backfill material 50 that protrudes into the joints M between adjacent irregular stones 20 seals the joints M.

[0050] If there is insufficient backfilling material 50 to fill the joints M between adjacent irregular stones 20, the backfilling material 50 is filled into the joints M from above the irregular stones 20 using a piping bag or the like.

[0051] Next, the other end of the stone-pulling hardware 22 is bent using pliers or the like and hooked onto the vertical reinforcement 30A, horizontal reinforcement 30B, or the intersection of the vertical reinforcement 30A and horizontal reinforcement 30B of the base mesh 30 around the irregular stone 20. At this time, the other end of the stone-pulling hardware 22 is hooked onto the vertical reinforcement 30A or horizontal reinforcement 30B of the base mesh 30 without any gaps so that the stone-pulling hardware 22 does not rattle.

[0052] By repeating the above procedure, a plurality of irregular shaped stones 20 are randomly laid on the wall surface 10S of the wall 10 via the base mesh 30 and backfill material 50.

[0053] The wet random laying method for irregular stone according to this embodiment is not limited to the above-mentioned procedure, and the procedure may be changed as needed. For example, other steps may be added to the above-mentioned procedure, or unnecessary steps may be omitted from the above-mentioned procedure.

[0054] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0055] According to this embodiment, a base mesh 30 is attached to the wall surface 10S of the wall 10. A plurality of irregular stones 20 are attached to the wall surface 10S of the wall 10 on top of this base mesh 30 via backfill material 50. In addition, stone puller hardware 22 attached to the irregular stones 20 is hooked onto the base mesh 30. The stone puller hardware 22 prevents the irregular stones 20 from peeling off from the wall surface 10S of the wall 10, for example, during an earthquake.

[0056] Furthermore, by attaching the base mesh 30 with a fine mesh R to the wall surface 10S of the wall 10, the stone guide hardware 22 can be easily attached to the base mesh 30 even for irregular stone 20. In particular, by making the size of the mesh R smaller than the size (external dimensions) of the irregular stone 20, the stone guide hardware 22 for the irregular stone 20 can be attached to the base mesh 30 more reliably.

[0057] Furthermore, since the base mesh 30 is planar, the number of attachment points to the wall surface 10S of the wall 10 is reduced compared to the conventional wet stonework method of attaching the flow-through rebars to the wall surface by driving anchors at intervals between the flow-through rebars. This improves the workability of the base mesh 30.

[0058] In this manner, in this embodiment, peeling of the irregular stones 20 from the wall surface 10S of the wall 10 can be suppressed, and workability can be improved.

[0059] The base mesh 30 is attached to a plurality of anchors protruding from a wall surface 10S of the wall 10 with a gap therebetween.

[0060] By providing a gap between the base mesh 30 and the wall surface 10S of the wall 10 in this manner, it becomes easier to hook the stone-pulling hardware 22 onto the vertical reinforcement 30A, the horizontal reinforcement 30B, or the intersections of the vertical reinforcement 30A and the horizontal reinforcement 30B of the base mesh 30. This improves workability.

[0061] Furthermore, by leaving a gap between the base mesh 30 and the wall surface 10S of the wall 10, the base mesh 30 is placed in the center of the thickness of the backfill material 50 of the irregular stone 20, which suppresses cracking of the backfill material 50, improves the adhesion of the irregular stone 20, and prevents efflorescence, which is likely to occur in wet areas such as large baths and in outdoor areas exposed to rain.

[0062] Furthermore, in conventional wet stone cladding methods, each rebar is attached to an anchor that protrudes from the wall surface. Therefore, narrowing the vertical pitch of the rebars increases the number of anchors required, which increases the effort required to attach the anchors to the wall surface.

[0063] In contrast, the base mesh 30 of this embodiment is planar, so it is possible to reduce the number of anchors 12 provided on the wall surface 10S of the wall 10, compared to the conventional wet stonework method of attaching flow-through rebars to the wall surface by driving anchors at intervals between the flow-through rebars. This further improves workability.

[0064] (Variation) Next, a modification of the above embodiment will be described.

[0065] In the above embodiment, the base mesh 30 is welded to the anchors 12. However, the method of attaching (joining) the base mesh 30 to the anchors 12 can be changed as appropriate. For example, in the modified example shown in Fig. 5, the anchors 12 are butted against the intersections of the vertical reinforcement 30A and the horizontal reinforcement 30B in the base mesh 30.

[0066] A pair of nuts 60 are attached to the anchor 12. The pair of nuts 60 are arranged on both sides of the intersection of the base mesh 30, and sandwich the intersection from both sides via a pair of washers 62. In this way, the base mesh 30 is attached to the anchor 12. By using the pair of nuts 60 or the like in this way, the base mesh 30 can be easily attached to the anchor 12.

[0067] In the above embodiment, the base mesh 30 is attached to the wall surface 10S of the wall 10 via a plurality of anchors 12. However, the base mesh 30 is not limited to being attached to the anchors 12, and may be attached to the wall surface 10S of the wall 10 via, for example, a bracket such as an angle bracket.

[0068] In the above embodiment, the base mesh 30 is a wire mesh. However, the base mesh 30 is not limited to a wire mesh, and may be, for example, a wire mesh or an expanded metal.

[0069] Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and one embodiment and various modified examples may be used in appropriate combination, and it goes without saying that the present invention can be implemented in various forms as long as it does not deviate from the gist of the present invention.
