Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for attaching wall covering panels.

[Prior art] Conventionally, when installing wall covering boards, double-sided adhesive mats have been relied upon as the initial adhesive until the adhesive hardens, but this technology has improved the ability to absorb uneven surfaces of the base and effectively thicken the adhesive. Due to these conditions, there is a gap of 3 to 5 mm between the base and the wall covering board, so the thickness of the double-sided adhesive mat is also around that, so when installing a large wall covering board, the mat itself may deform due to its weight. As a result, it was difficult to prepare the joints in the wall covering.

Therefore, as shown in FIGS. 6 and 7, in order to receive the weight of the wall covering board 1, a supporting metal fitting 3 is placed at the bottom of the board.
Attempts have been made to install support metal fittings in a straight line, but it is difficult to fix the support metal fittings in a straight line, and it is also difficult to fix the support metal fittings on the exterior of the wall covering. In addition, since it is disliked that the metal fittings are exposed on the exterior of the wall covering board, the contact area with the wall covering board is small, making it difficult to correct the position of the board, etc.
Furthermore, the risk of falling out of the plane has not been improved.

Furthermore, as in Utility Model Publication No. 51-35356, a method has been proposed in which an adjustment fitting that absorbs the irregularities of the base is fixed to the wall covering board with double-sided adhesive mat, but once the wall covering board is installed, It is difficult to adjust, and since the adjustment screws of the metal fittings are located at the joints, the joint width cannot be narrowed, which is not aesthetically pleasing. Furthermore, since the initial adhesion until the adhesive hardens depends solely on the adhesive strength of the double-sided adhesive mat attached to the metal fittings, there remains a concern that the wall covering board may fall off.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and includes a mounting plate having a folded stepped portion on the base side on the upper part of the wall covering board. Prior to construction, a wall covering plate with a mounting plate is prepared by positioning the folded stepped part of the mounting plate slightly below the top edge of the wall covering plate and adhering it via an adhesive film, and then To provide a method for attaching a wall covering board, which is characterized by suspending the wall covering board by screwing it to a base to be constructed, and fixing several places on the back side of the wall covering board to the base using an elastic adhesive. It is something.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

In the present invention, as shown in FIGS. 2 and 3, the mounting plate 6 is firmly attached to one side of the upper part of the wall covering plate 1 by adhesive film 7 so as to be located a predetermined distance inward from both ends of the plate. Glued. Mounting plate 6
The reason for specifying the mounting position as above is that in addition to making it possible to cut the three sides of the wall covering board 1, namely the left and right sides and the lower part, to match the mounting position, the wall covering board can be installed by lifting it up as shown in the figure. This is because the wall covering board 1 can be constructed with a beautiful surface without being distorted by its own weight, and since the upper part is suspended, there is no need to worry about it falling out of the surface. Note that a plurality of mounting plates 6 may be provided along the upper side of the wall covering plate 1.

It is desirable for the mounting plate 6 to have sufficient tensile strength against the weight of the wall covering board and a linear expansion coefficient close to that of the wall covering board in terms of adhesive durability, and is usually made of SUS430 or
SUS304 is suitable. As shown in Figure 3, this mounting plate connects the joint of the wall covering board and the attachment part to the base 2 so that the thickness of the elastic adhesive 5 can be secured between the base 2 and the wall covering board 1 during construction. It has a bent step in between. The width of this step (bending height) is usually 3~
It is 5mm. Further, the thickness of the mounting plate 6 is adjusted so that the plate rigidity is not too large in order to improve the adhesion with the wall covering plate.

In the present invention, the mounting plate 6 is adhered to the upper part of the wall covering plate 1 using an adhesive film 7 such as ethylene vinyl acetate resin, urethane resin, silicone resin, or polyvinyl butyral resin. This adhesion can be achieved by vacuum evacuation between the adhesive film interposed between the wall covering board 1 and the mounting plate, and then heat-pressing. For this reason, the mounting plate 6 is attached to the wall covering board 1 prior to construction of the wall covering board 1.

To actually construct the wall covering board 1 according to the present invention,
The mounting plate 6 attached to the wall covering plate is fixed to the base 2 with screws 9, for example. In this case, elastic adhesive 5 is applied to the back surface of wall covering board 1 in several places.
A wall covering board 1 is adhesively fixed to a base 2 for a long period of time. Furthermore, it is desirable to provide a presser plate 8 on the lower back of the wall covering plate 1 in order to maintain the distance from the base 2. That is, this presser plate 8 is provided on the wall covering board side or the base side, and functions as a thickness guide when the elastic step molding adhesive 5 hardens, and also serves as a reaction force point when wind pressure is applied from the outside.
It also plays a role in adjusting the unevenness of the base. Note that depending on the properties of the base 2, nails may be used instead of the screws 9, and the term "screw fastening" includes both of these.

When a plurality of wall covering boards 1 are installed vertically along a wall surface according to the present invention, they are stacked one after another from the bottom. It is convenient to install the joint bar 10 by lowering it slightly from the upper end of the board 1 and using this location. At this time, it is preferable that the joint rod 10 goes inside the wall covering board 1 so that the sealing work can be performed from the outside.

4 and 5 show other embodiments of the invention. In Figure 4, a support part 11 is provided by bending the upper part of the mounting plate 6 so that it also serves as a holding plate 8, and in Figure 5, a metal fitting 12 is provided below the wall covering board 1, and a supporting part 11 is provided by bending the upper part of the mounting plate 6. When the boards 1 are stacked in the vertical direction, the lower part of the wall covering board 1 is fixed to the base 2 by locking the upper end of the mounting plate 6 of the lower wall covering board 1 to the metal fitting 12. .

[Effects of the Invention] As described above, in the present invention, since the mounting plate is attached using an adhesive film, the adhesive strength is maintained over a long period of time, and the wall covering plate can be safely attached. Moreover, since the wall covering board is screwed to the base, unlike conventional double-sided adhesive mats, the wall covering board can be firmly supported to prevent it from slipping down. Furthermore, the mounting plate is not exposed at all at the joint, and the joint width can be narrowed, so it is aesthetically superior.

Furthermore, since the mounting plate is located at the center of the upper side of the wall covering board, the left and right sides and lower part of the wall covering board can be cut to the desired size while the mounting plate remains attached. I can do it.
