Description

Article 30, Paragraph 2 of the Patent Act applies. Published on March 19, 2021 by Ex-Knowledge Co., Ltd. in "Architectural Knowledge April Issue, Vol. 63, No. 797, pp. 80-81"

The present invention relates to a wet random laying structure for irregular stone materials and a wet random laying construction method for irregular stone materials.

A wet stone veneer construction method is known in which multiple stones formed to a predetermined shape and size (hereinafter referred to as "pre-shaped stones") are attached to the wall surface via a backfill material such as mortar (see, for example, Patent Documents 1 and 2).

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.

Japanese Patent Application Publication No. 10-252243 Japanese Unexamined Patent Publication No. 63-247465

In the above-mentioned 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 surface of a wall using the above-mentioned wet stone laying method, there is a possibility that there will not be any reinforcing bars around the standard stone materials to which stone trigger hardware can be attached.

One possible solution to this problem would be to narrow the pitch of the rebars, but this would increase the number of rebars required. This would make it more time-consuming to attach the rebars to the wall surface, potentially reducing workability.

The present invention takes the above into consideration and aims to improve workability while suppressing the peeling of irregular stone materials from the wall surface.

The wet random-laying structure of irregular stone in the first embodiment 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.

According to the first aspect of the wet random-laying structure for irregular stone, a base mesh is attached to the wall surface. A plurality of irregular stone elements are attached to the wall surface from above the base mesh via backfill material. Furthermore, stone guide hardware attached to the irregular stone elements is hooked onto the base mesh. The stone guide hardware prevents the irregular stone elements from peeling off from the wall surface.

In addition, 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.

Furthermore, because the base mesh of the present invention is planar, it requires fewer attachment points to the wall surface compared to conventional wet stonework methods, which involve installing rebars on the wall surface by driving anchors at intervals between rebars. This improves the workability of the base mesh.

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

The second aspect of the wet random-laying structure for irregular stone materials is the same as the first aspect of the wet random-laying structure for irregular stone materials, and is provided with a plurality of anchors 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.

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

By leaving 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.

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 prevents cracks in 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.

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

In contrast, the base mesh of the present invention is planar, so it is possible to reduce the number of anchors required on the wall surface compared to the conventional wet stonework method, which involves driving anchors at intervals between the rebars to attach them to the wall surface. This further improves workability.

The third aspect of the wet random laying method for irregular stone involves attaching irregular stone to the wall surface via a backfill material on top of a base mesh attached to the wall surface, and hooking stone trigger hardware attached to the irregular stone onto the base mesh.

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

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

Furthermore, because the base mesh of the present invention is planar, it requires fewer attachment points to the wall surface compared to conventional wet stonework methods, which involve installing rebars on the wall surface by driving anchors at intervals between rebars. This improves the workability of the base mesh.

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

As explained above, the present invention can improve workability while suppressing the peeling of irregular stone materials from the wall surface.

Below, we will explain one embodiment of a wet random laying structure and a wet random laying method for irregular shaped stone, with reference to the drawings.

(irregular shaped 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 irregular stones 20 are irregularly shaped (randomly shaped) stones with different shapes and sizes. These irregular stones 20 may be, for example, natural stone or artificial stone.

(Base mesh)
A 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 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 grid pattern. The mesh size R of the base mesh 30 is smaller than that of the irregular stones 20.

The base mesh 30 is arranged along the wall surface 10S of the wall 10 and is attached to multiple anchors 12 protruding from the wall surface 10S of the wall 10. The multiple anchors 12 are arranged at intervals in the height and width directions of the wall 10. In addition, multiple meshes R of the base mesh 30 are arranged between adjacent anchors 12.

As shown in Figure 2, the base mesh 30 is attached to multiple anchors 12 at a distance from the wall surface 10S of the wall 10. The multiple 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 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.

The lower part of the base mesh 30 is attached to a plurality of anchors 42 that protrude upward from the floor 40. The anchors 42 are installed after being driven into the floor 40. The anchors 42 are spaced apart in the width direction of the wall 10. At least one of the vertical reinforcement 30A and horizontal reinforcement 30B of the base mesh 30 is joined to the tip end (upper end) of these anchors 42 in the protruding direction by welding or the like.

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

The wall 10 is made of reinforced concrete and rises from the floor 40. This wall 10 is, for example, the wall of a bathroom (large communal bath), and the lower part of the wall surface 10S is waterproofed by a waterproof layer 14. Therefore, the anchors 42 in this embodiment are installed on the floor 40, not on the lower part of the wall 10. However, it is also possible to install anchors similar to anchors 12 on the lower part of the wall 10 and attach the base mesh 30 to these anchors.

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 also be a dry wall.

(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.

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

Additional materials may be added to the backfill material 50 as needed.

(Stone-pulling 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.

Specifically, as shown in Figure 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 hole is filled with a filler such as adhesive, thereby fixing the stone puller hardware 22 to the upper end of the irregular stone 20.

The other end of the stone puller 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 puller 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.

In this embodiment, the horizontal reinforcement 30B of the base mesh 30 is positioned above the vertical reinforcement 30A. In other words, multiple vertical reinforcement 30A is positioned between the multiple horizontal reinforcement 30B and the wall surface 10S of the wall 10. This makes it easier to hook the stone-drawing hardware 22 onto the horizontal reinforcement 30B than onto the vertical reinforcement 30A.

In addition, at least one stone pull hardware 22 can be provided on the irregular stone 20. Furthermore, the stone pull hardware 22 is not limited to being provided on the top end of the irregular stone 20, but may also be provided on, for example, the side end of the irregular stone 20.

(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.

As shown in Figure 3, first, multiple anchors 12 are driven into the wall surface 10S of the wall 10, and multiple anchors 42 are driven into the upper surface of the floor 40. Next, the base mesh 30 is attached to the multiple anchors 12, 42 while leaving a gap between them and the wall surface 10S of the wall 10.

More specifically, the vertical reinforcement 30A, horizontal reinforcement 30B, or the intersections of the vertical reinforcement 30A and horizontal reinforcement 30B of the base mesh 30 are joined by welding or the like to the tip end of the protruding direction of the multiple anchors 12. Furthermore, the vertical reinforcement 30A and horizontal reinforcement 30B at the bottom of the base mesh 30 are joined to the multiple anchors 42 by welding or the like. From the standpoint of joint strength, it is desirable to join the intersections of the vertical reinforcement 30A and horizontal reinforcement 30B of the base mesh 30 to the anchors 12.

Next, the backfill material 50 is applied to the wall surface 10S of the wall 10 over the base mesh 30 using a trowel or similar tool, without gaps and with a generally uniform thickness. It is also desirable to apply an adhesion enhancer to the wall surface 10S of the wall 10 in advance.

Next, the irregular stone 20 is temporarily placed on the base mesh 30, and the spacing (joints M) between adjacent irregular stone 20 is adjusted. At this time, if necessary, the shape (external shape) of the irregular stone 20 is adjusted using power tools or a hammer.

Next, the irregular stone 20 is removed from the wall surface 10S of the wall 10, and a stone guide 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 similar tool (not shown). Then, with one end of the stone guide hardware 22 inserted into the mounting hole 24, a filler such as adhesive is filled in. By repeating this procedure, multiple stone guide hardware 22 are attached to the irregular stone 20.

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

If there is insufficient backfill material 50 to fill the joints M between adjacent irregular stones 20, backfill material 50 is filled into the joints M from above the irregular stones 20 using a piping bag or similar.

Next, bend the other end of the stone-pulling hardware 22 using pliers or similar tools and hook it 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, hook the other end of the stone-pulling hardware 22 onto the vertical reinforcement 30A or horizontal reinforcement 30B of the base mesh 30 without any gaps to prevent the stone-pulling hardware 22 from rattling.

By repeating the above steps, multiple irregular stone blocks 20 are randomly laid on the wall surface 10S of the wall 10 via the base mesh 30 and backfill material 50.

Note that the wet random laying method for irregular stone materials according to this embodiment is not limited to the above steps, and for example, the steps may be rearranged as needed. Also, for example, other steps may be added to the above steps, or unnecessary steps may be omitted from the above steps.

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

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 from above the 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.

Furthermore, by attaching a 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 more securely attached to the base mesh 30.

Furthermore, because 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, in which anchors are driven into the wall at intervals between the rebars to attach them to the wall surface. This improves the workability of the base mesh 30.

In this way, this embodiment can improve workability while suppressing the peeling of irregular stone materials 20 from the wall surface 10S of the wall 10.

The base mesh 30 is attached to a plurality of anchors protruding from the wall surface 10S of the wall 10 with a gap between them.

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

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 outdoor areas exposed to rain.

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

In contrast, the base mesh 30 of this embodiment is planar, so compared to the conventional wet stonework method of attaching rebar to the wall surface by driving anchors at intervals between rebars, the number of anchors 12 installed on the wall surface 10S of the wall 10 can be reduced. This further improves workability.

(Modification)
Next, a modification of the above embodiment will be described.

In the above embodiment, the base mesh 30 is welded to the anchor 12. However, the method of attaching (joining) the base mesh 30 to the anchor 12 can be changed as appropriate. For example, in the modified example shown in Figure 5, the anchor 12 is butted against the intersection of the vertical reinforcement 30A and the horizontal reinforcement 30B in the base mesh 30.

A pair of nuts 60 are attached to the anchor 12. The pair of nuts 60 are positioned on both sides of the intersection of the base mesh 30, sandwiching the intersection from both sides via a pair of washers 62. This attaches the base mesh 30 to the anchor 12. By using a pair of nuts 60 in this way, the base mesh 30 can be easily attached to the anchor 12.

In addition, in the above embodiment, the base mesh 30 is attached to the wall surface 10S of the wall 10 via multiple anchors 12. However, the base mesh 30 is not limited to being attached to the anchors 12, and may also be attached to the wall surface 10S of the wall 10 via, for example, brackets such as angles.

In addition, 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 expanded metal.

The above describes one embodiment of the present invention, but the present invention is not limited to this embodiment. One embodiment and various modified examples may be used in appropriate combination, and the present invention can of course be implemented in various forms without departing from the spirit of the present invention.
