Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a stone lining construction method for constructing the exterior wall surface of a building. In particular, the present invention relates to a stone lining construction method that can quickly drain water that has entered through joints in the exterior wall of a building or cracks in stone slabs to prevent whitening of the exterior wall of the building.

(Prior Art) From the viewpoint of durability, aesthetics, etc., stone walls are formed by pasting stone plates as exterior materials on the exterior walls of buildings, especially concrete buildings.

Conventionally, the method of constructing the exterior of a concrete building using stone slabs has generally been to engage each stone slab one by one with a trigger tool whose one end is fixed to the concrete exterior wall surface. Then, after hardening the area near the stone plate of this metal fitting with plaster to fix the stone plate, soft mortar (toro) is poured into the gap between the back side of the stone plate and the outer wall surface, and this mortar is hardened to remove the stone plate. This is done by removing the plaster after it has been completely fixed to the wall.

During this construction, narrow grooves or holes are usually bored in the upper and lower ends of the stone slab in order to engage with the concrete outer wall surface, and the trigger tool is fitted into these grooves or holes and fixed. in particular,
Diameter at the top and/or bottom end of a 50mm thick stone slab
A hole of about 10 mm is drilled and a trigger is inserted into this hole to prevent the masonry wall from collapsing.

(Problem to be Solved by the Invention) However, since grooves or holes must be drilled at the upper and/or lower ends of the stone slab, and the plaster must be removed after hardening, construction is only carried out one stage at a time. This was not possible and required a large amount of money and time.

In addition, when masonry was being laid, the position of the stones had to be finely adjusted, and trenches or holes had to be drilled at the construction site, resulting in a longer construction period.

On the other hand, in the conventional stone cladding construction method, after filling the joints between the stone slabs, mortar was filled between the exterior wall surface and the stone slabs, and the stone slabs were attached to the exterior wall surface, which was time-consuming. Over time, problems such as rainwater that entered through joints or cracks dissolved the concrete and dripped onto the surface of the stone and dried, resulting in whitening (runny nose) of the stone surface.

These bleaching types are granite (black granite, red granite), serpentine (kisabimon), limestone (sarasa), andesite (teppeishi).
This phenomenon is particularly noticeable in stones of colors other than white, such as black, red, and green, and a means to prevent this whitening has been desired.

(Means for Solving the Problems) [Summary of the Invention] <Object of the Invention> The stone cladding method of the present invention has been made in order to solve the problems of the prior art described above, and its purpose is to To provide a stone lining construction method that can inexpensively and quickly affix stone slabs to a wall surface and prevent whitening (runny nose) of the stone surface.

<Structure of the Invention> In other words, the stone cladding method of the present invention is a stone cladding method in which a stone slab is attached to the exterior wall of a building, in which the stone slab is placed at a predetermined distance from the exterior wall, and the stone slab is placed at a predetermined distance from the exterior wall. The stone slabs and the exterior wall surface are bonded together using a quick-acting adhesive via spacers, and a joint is filled between the stone slabs, and then a conductor is placed between the exterior wall surface and the stone slab along this joint. After the water channel is provided, mortar is filled between the outer wall surface and the stone plate to attach the stone plate to the outer wall surface.

<Effects> If the stone cladding method of the present invention is used,
The following effects (1), (2), and (3) can be obtained.

(1) According to the conventional masonry work method, the next level of stone slabs was piled up after the toro (soft mortar) had hardened, but according to the stone work method of the present invention, fast-acting adhesive Since this method is used, the construction time for the stone wall is short, and therefore, it is possible to perform several stages of masonry in one day, and the construction period can be shortened at low cost.

(2) In the stone cladding method of the present invention, after filling the joint between the stone slabs, a water conduit is provided between the outer wall surface and the stone slab along this joint, so Rainwater that enters through the cracks is drained out through the conduit, so the rainwater that dissolves the concrete drips onto the surface of the stone and dries, resulting in whitening (snot).
Since this phenomenon can be prevented, it is ideal for stone masonry work with colored stones such as black, red, and green.

(3) Since vibrations and deformations from the outer wall surface are only transmitted partially through the spacer, the vibrations and deformations can be absorbed and reduced by the spacers. Therefore, it is possible to improve the accuracy of stone cladding work.

[Example] Specific examples of the stone cladding method of the present invention will be described in detail below based on the drawings.

Examples of the stone used in the stone cladding method of the present invention include natural stone slabs such as granite and marble, and artificial stone slabs such as terrazon and Neopalier (trademark).

Preferable stone materials used in the stone cladding method of the present invention include granite (black granite, red granite), serpentine (kisabimon), and limestone (saltstone) because they can prevent the whitening (runny nose) phenomenon described later. ),
Examples include stones of colors other than white, such as black, red, and green, such as andesite (teppeishi).

As shown in FIG. 1, the stone cladding construction method of the present invention includes a stone slab 2 placed on an outer wall surface 1 of a building made of concrete or the like.
When placing the concrete, the outer wall surface 1 of the concrete, etc.
The stone slab 2 is placed with a predetermined narrow space between the stone slab 2 and the stone slab 2, and the placed stone slab 2 and the outer wall surface 1 are bonded with a quick-acting adhesive via a spacer to perform masonry construction. It will be done.

There is a joint 7 between these stone plates 1 and 1.
After filling, the outer wall surface 1 is filled along this joint 7.
After providing a conduit 11 between the outer wall surface 1 and the stone slab 2, mortar 8 is filled between the outer wall surface 1 and the stone slab 2, and the stone slab 2 is attached to the outer wall surface 1, thereby completing the stone laying work. Complete.

An embodiment of the stone cladding method of the present invention will be described below.

First, the stone slab 2 to be placed on the outer wall surface 1 is prepared. The dimensions, material, etc. of this stone plate 2 are arbitrary, but
For example, one with a thickness of about 25 mm is used.

To install such a stone plate 2, first, as shown in FIG. 2, the lower gasket 4 is placed in a predetermined place, and then adjusted so that the stone plate 2 is installed horizontally.

Next, the stone plate 2 is adjusted so that it is parallel to the outer wall surface 1, and a fast-acting adhesive is applied to both the adhesive surfaces of the spacer 3 on the outer wall surface 1 side and the stone plate 2 side,
This spacer 3 is set between the stone plate 2 and the outer wall surface 1, and pressed for a while to maintain the bonded state.
Wait for the quick-acting adhesive to harden.

The spacer 3 may be set perpendicularly to the outer wall surface 1, or may be installed between the stone plate 2 and the outer wall surface 1 at a certain angle as shown in FIG. 2b.

The adhesive used in the masonry construction method of the present invention must be fast-acting, and the construction period cannot be shortened unless it produces sufficient adhesive strength within several minutes to several hours.

Such an adhesive varies depending on the material of the stone 2 and the type, material, and dimensions of the spacer 3, but for example, a long-lasting cyanoacrylate adhesive (for example, Beauty East Stone #250 manufactured by Sanwa Chemical Center) and 500), epoxy adhesives, etc.

The spacer 3 used in the stone cladding method of the present invention is made of a material that functions to maintain a constant distance between the stone slab 2 and the outer wall surface 1. Examples include iron, steel, stainless steel, copper, aluminum alloy, ceramic, plastic, and wood.

The shape and dimensions of the spacer 3 are arbitrary as long as it does not contradict the purpose of the present invention, but it is generally rod-shaped or plate-shaped, and as shown in FIG. It is desirable that the step be formed, and by forming it in such a step,
It is bonded to the side and back sides of the stone 2 to increase the bonding area and make it difficult to peel off, and since it is bonded to the side of the stone 2, shear stress is generated and the stone 2 does not fall toward the worker. It is difficult to adhere and can be bonded more firmly.

After one stone plate 2 is attached to the outer wall surface 1, or at the same time, the same operations as described above are repeated to construct the first row of stone walls. A backup material may be provided at the upper end of the stone plate 2 if necessary.

After the construction of the first row of stone walls, the second row of stone plates 2
is placed on the first row of stone plates 2, and in the same manner as described above, this stone plate 2 is bonded to the outer wall surface 1 via the spacer 3 with a fast-acting adhesive.

Repeat these steps to stack up stone slabs 2,
The gaps between the stone plates 2 are filled with joints 7, and the stacking of the stone plates 2 is completed.

A water conduit 1 consisting of a rope, a spiral pipe, a mesh pipe, etc. is placed on the outer wall surface 1 side of this joint 7.
1, a soft mortar (toro) 8 is poured into the gap between the back side of the stone plate 2 where the water conduit 11 is provided and the outer wall surface 1, and this mortar 8 is hardened to move the stone plate 2 to the outer wall surface 1. The stone wall is completed when it is completely fixed.

By providing the water conduit 11 on the outer wall surface 1 side of the joint 7 in this way, rainwater, etc. that has entered through the deteriorated part due to shrinkage of the joint 7 over time and the cracks in the stone slab 2 can be quickly removed. By discharging the concrete, it is possible to prevent the phenomenon of whitening (runny nose) of the outer wall surface caused by rainwater that has dissolved the concrete.

The stone masonry construction method of the present invention is not limited to the above-mentioned embodiment, but can be modified and implemented in various ways.

For example, in the above-mentioned embodiment, when the stone is laid, soft mortar (toro) 8 can be poured into the back side of the stone slab 2, except for the conduit 11 provided on the outer wall surface 1 side at the joint 7. Although a hollow portion is formed, it can be filled with cello packing 9 as shown in FIG.

In such an embodiment, after the stone plate 2 is adhered to the outer wall surface 1, the trowel 8 is poured in, then cello packing is filled, and the trowel 10 is poured again. With this modification, it is possible to adhere the stone plate 2 more firmly and to save mortar in the area filled with ceroplast.

Moreover, by making the shape of the spacer 3 constricted at the center part 5 as shown in FIG.
External wall surface 1 of the building under construction at this constriction
This is preferable because vibrations such as earthquakes transmitted to the stone wall and distortions such as deformation due to expansion and contraction of the material are not directly transmitted to the stone plate 2 and can be absorbed and buffered, which can alleviate breakage and damage to the stone wall. .

Further, FIG. 6 shows an embodiment in which a stone plate 2 is attached to an overhanging outer wall surface 1 such as a beam portion.

The stone wall 2 of this type has a stone plate 2 placed on a support stand 12 arranged at a predetermined distance from the outer wall surface 1.
After placing the stone plate 2 and adjusting the position of the stone plate 2 to match the outer wall surface 1, a fast-acting adhesive is applied to the adhesive surface of the outer wall surface 1 and the stone plate 2 on which the spacer 3 will be installed, and the spacer 3 is
is set between the stone slab 2 and the outer wall surface 1, pressed for a while to maintain the bonded state, and wait for the fast-acting adhesive to harden.

Next, another stone slab 2 is stacked on the outer wall surface 1 adjacent to the stone slab using another spacer 3, and the above-mentioned operations are repeated to form a first stage of stone stacking. Furthermore, similarly to the construction of the first stage of masonry, the stone plates 2 are laid down along the outer wall surface 1 using spacers 3. Finally, the support stand 12 is removed and construction is carried out.
