Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for fixing architectural cladding materials such as tiles, which can firmly fix architectural cladding materials such as tiles to the base of interior and exterior surfaces of buildings.

(Prior art) As a method of fixing architectural cladding materials such as tiles and stones to the interior and exterior surfaces of buildings, cement mortar, cement mortar mixed with a synthetic resin admixture, or synthetic resin adhesive is used. The crimp tensioning method, in which construction materials are piled up one by one from the bottom and crimped, is known as a general method.ζ
There is.

In addition, there is a net-laying method that is an improved version of this pressure-bonding method, in which tiles smaller than a small tile are pasted in a predetermined arrangement on a net approximately 30 cm square, and then covered with cement mortar or adhesive on the interior and exterior surfaces. There are also construction methods.

Furthermore, as described in Japanese Utility Model Publication No. 57-55469, a tile tensioning member into which tiles can be inserted is fixed to the base in advance, and the tiles are inserted into this tile tensioning member and stretched. There are also known methods.

(Problems to be Solved by the Invention) However, when using the above-mentioned pressure bonding method, the cement mortar, the cement mortar mixed with a synthetic resin admixture, or the synthetic resin adhesive increases hardness and decreases flexibility after construction. Because of this, it is not possible to absorb the expansion, contraction, and vibration of the building frame, and as a result, the base material and the cladding material separate, and the cladding material often peels off, causing it to swell from the wall surface. Generally speaking, the joints are prepared in advance to prevent the above-mentioned separation, but this is insufficient because the joints may also peel off due to vibrations of the building structure. Note that when synthetic rubber-based adhesives are used, regardless of whether they are water-soluble or solvent-based, they are sensitive to rainwater, so they are not used as exterior adhesives except in special cases.

When using the above-mentioned net tensioning method, there is an advantage that the work can be done more efficiently because the construction materials such as tiles can be pasted together in nets, but the problem of peeling of tiles, etc. occurs in the same way as with the pressure bonding method, and has not been solved. Not yet. In other words, the net in this case is simply attached to the tiles to the extent that the tiles and other adhesive materials do not fall off during transportation or work, and the tiles are not attached to the base by the adhesive force between the net and the tiles. Since tiles and the like are fixed to the substrate using cement mortar, cement mortar mixed with a synthetic resin admixture, or synthetic resin adhesive, problems of peeling occur as in the case of the pressure bonding method.

In addition, when using tile installation materials, there is no problem of tiles peeling off, but because tiles are inserted and fixed in sequence on either the left or right side, tiles may be partially damaged and need to be replaced. In such a case, it is impossible to repair just one tile, and it would be unreasonable to have to replace all the tiles in the same row.

There is also a method of drilling nail holes in the tile and fixing the tiles so as to cover the nail holes one after another, but this is also unreasonable as it makes partial repair difficult.

Therefore, the present invention has been made to solve the various problems mentioned above.The purpose of the present invention is to prevent the construction material from peeling off easily even when the building frame expands and contracts or vibrates, and to provide weather resistance. To provide a method for fixing architectural cladding materials that can be finished on interior and exterior surfaces that can be easily repaired.

(Means for solving the problem) The above purpose is to partially fix a mesh reinforcing material on the base surface such as the interior and exterior surfaces of a building structure, and then to interpose this mesh reinforcing material. This is achieved by a method for fixing a construction cladding material, which is characterized in that the construction cladding material is also partially adhered and fixed onto the base with an adhesive.

The mesh reinforcement material is preferably one made of braided glass fibers.

Furthermore, silicone-based adhesives are particularly effective as they maintain flexibility even after curing.

(Function) Architectural tensioning materials and mesh reinforcing materials are partially bonded to the base using an adhesive with high adhesive strength, so unlike if the entire structure is bonded, the bond will not adhere even if the building frame expands, contracts, or vibrates. Stress concentration on the adhesive portion is avoided, and the base and adhesive do not peel off. Furthermore, even if the base and adhesive should peel off, and the joints should also peel off, the construction adhesive will not fall off from the base because it is adhered to the continuous mesh reinforcing material.

Furthermore, since the mesh reinforcing material is interposed in the adhesive, the strength of the adhesive itself is increased, and destruction of the adhesive portion due to expansion and contraction of the frame, vibration, etc. is avoided.

If the adhesive is silicone-based, it maintains its softness even though it has a high adhesive strength, so the expansion and contraction of the building block and vibrations are further absorbed, and peeling between the base and the adhesive is further inhibited. .

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

10 indicates the base material which becomes the interior and exterior surfaces of the building structure 1-.

The base 10 may be concrete, mortar, slate board, or plywood.

In the present invention, first, the mesh reinforcing material 12 is attached to the surface of the base 10.
to be fixed. As shown in the drawings, the mesh reinforcing material 12 is fixed on the base 10 in sections using nails or adhesives at appropriate intervals and stretched over the entire surface of the base.

The mesh reinforcing material 12 needs to be fixed on the base 10 with at least enough strength to prevent it from falling off the base 10 during the subsequent work of fixing the construction material, but it is not necessarily fixed firmly on the base 10. It is not necessary.

Although the material of the mesh reinforcing material 12 is not particularly limited, a material made of glass fibers braided into a mesh shape is particularly suitable. Alternatively, stainless steel wire mesh or high-strength resin mesh can be used.

Next, the construction adhesive material 14 is laid out on the base 10, and the construction adhesive material 1 is placed on the base 10 via the mesh reinforcing material 12.
4 is fixed, and this construction cladding material 14 is fixed using an adhesive. That is, on the base 10, or on the back side of the construction adhesive 14, or on the base 10 and the construction adhesive 1.
An adhesive is applied to both sides of 4 to fix the construction cladding material 14. At that time, each building tension material 14 is connected to the mesh reinforcement material 12.
It is essential that it is also partially fixed onto the substrate 10 via the.

For this purpose, the adhesive is applied in dots or strips on the base 10, the back surface of the construction adhesive 14, or both. When fixing the construction adhesive material 14 onto the base 10, a portion of the applied adhesive is positioned on the mesh reinforcing material 12 at a plurality of locations. As a result, the mesh reinforcing material 12 as well as the building adhesive material 14 are fixed onto the base 10 by the adhesive. Therefore, the above adhesive is applied on the base 10,
If the adhesive is applied in a band shape to one or both of the construction adhesive materials 14, the adhesive will necessarily intersect with the mesh reinforcing material 12, so there will be no need to check each time, and work efficiency will be improved.

An adhesive with high adhesive strength is used for fixing the architectural cladding material 14 and the mesh reinforcing material 12.

In other words, even by partial adhesion, the construction adhesive material 14 is attached to the base 1.
0 and the mesh reinforcing material 12 are used. As this adhesive, for example, an epoxy resin adhesive can be used. However, with epoxy resins, the hardness increases after curing and the impact resistance decreases, so it is preferable that after curing, the hardness does not increase and maintains flexibility, has excellent adhesive strength, and is corrosion resistant and weather resistant. Silicone adhesives with excellent properties are recommended. As the silicone adhesive, for example, Toray Silico-7SE5003RTV (trade name) and Toray Silicone 58780 (trade name) were good.

After the architectural cladding material 14 and the mesh reinforcing material 12 are fixed with an adhesive as described above, joints 16 are formed in the gaps between the architectural cladding materials 14 to complete the process.

As mentioned above, the construction tension material 14 and the mesh reinforcement material 12
is partially glued onto the base 10 using an adhesive with a high adhesive strength, so unlike if the entire piece is glued, stress will not be concentrated on the glued part even if the single piece construction piece expands, contracts, or vibrates. This prevents the adhesive from peeling off from the base.

Furthermore, even if the base and adhesive should peel off and the joints should also peel off, the building tensioning material 14 will not fall off from the base because it is adhered to the continuous mesh reinforcing material 12.

Furthermore, since the mesh reinforcing material 12 is interposed in the adhesive, the strength of the adhesive itself is increased, and destruction of the adhesive portion due to expansion/contraction, vibration, etc. of the 11 members is avoided.

If the adhesive is silicone-based, it maintains its softness even though it has a high adhesive strength, so the expansion and contraction of the building block and vibrations are further absorbed, and peeling between the base and the adhesive is further inhibited. . In addition to being excellent in weather resistance, these sprayed materials exhibit good adhesion regardless of whether the substrate is concrete, mortar, slate, or plywood, and also exhibit good adhesion to sprayed materials such as Bontile. Architectural cladding materials can be placed directly on top of the wall, making it easy to repair the wall surface.

To replace the architectural cladding material 14 such as a tile if it is damaged,
This can be done easily since it is only necessary to replace the construction cladding material 14 in the damaged area.

(Effects of the Invention) As is clear from the above, the present invention provides the following outstanding effects.

(a) Since the building materials and mesh reinforcing materials are partially adhered to the base, it is difficult to prevent the construction of buildings! Stress concentration on the adhesive part due to expansion and contraction of the opening and vibrations is avoided, and peeling of the base and construction adhesive material is suppressed, and even if separation occurs between the two, the construction adhesive material will remain on the continuous mesh reinforcement material. Since it is glued, the adhesive will not fall off.

Furthermore, since the mesh reinforcing material is present in the adhesive, the strength of the adhesive itself is increased.

(b) When a silicone adhesive is used as an adhesive, it remains soft after curing, so the expansion and contraction of the building frame and vibrations are further absorbed (absorbed), and the peeling of the construction cladding material from the base is further reduced. effectively deterred.

In addition, silicone-based adhesives not only adhere to concrete, mortar, slate, plywood, etc., but also have strong adhesion to sprayed materials such as Bontile, making it possible to attach construction materials to uneven foundations. Become. Furthermore, it has excellent weather resistance.
