Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for attaching a ceramic panel for interior and exterior to a wall of a skeleton made of concrete, fire-resistant board, veneer or the like.

[0002]

2. Description of the Related Art Conventionally, it has been common practice to attach a plurality of panels with excellent design to a wall made of cocrete of a building such as a building or a fire-resistant board or veneer, particularly an indoor wall. Is being done.

As interior / exterior panels for decorating by attaching to such indoor and outdoor wall surfaces, ceramic panels made of porcelain tiles and the like are used in addition to lightweight concrete panels. Although this ceramic panel can be designed with a fine and excellent design, it is hard and brittle compared to lightweight concrete panels, so if you try to fix it directly on the wall of the frame by driving screws or anchors, it will be broken or broken. There are drawbacks.

Therefore, when the ceramic panel is mounted on the wall of the frame, an elastic adhesive having an excellent adhesive force against vibration, shock and expansion and contraction of the material is applied to the back surface of the ceramic panel, and this elastic adhesive is used. In addition to being adhesively fixed to the wall of the skeleton, it was also attached to the wall using a fall prevention bracket.

For example, as shown in FIG. 5, a slit is formed on the upper edge of the rear surface of the ceramic panel 2, and a fall prevention metal fitting 3 is fitted into the slit and fixed with an adhesive.
After partially applying an elastic adhesive 4 and an adhesive spacer 5 to the back surface of the ceramic panel 2,
The ceramic panel 2 is pressed against the ceramic panel 2 by pressing the ceramic panel 2 with an elastic adhesive 4, and a screw or the like inserted into a hole of the fall prevention fitting 3 is screwed into an anchor plug 6 or the like previously fixed to the wall surface 1a. Was fixed to the wall surface 1a.

[0006]

In the above-mentioned conventional method for mounting a ceramic panel, the fall prevention fitting is fixed to the slit of the ceramic panel with an adhesive, and the fall prevention fitting is further fixed to the wall surface. However, the adhesive used for fixing the fall prevention bracket is generally an epoxy type adhesive, but there is no perfect adhesive in water resistance, weather resistance and durability, and it deteriorates over a long period of time That is inevitable.

For this reason, the fall prevention metal fittings are easily detached from the ceramic panel with the passage of time, and the durability of the attachment of the ceramic panel is lower than that of a frame having a durability of several decades. In particular, since the adhesive deteriorates more quickly outdoors outdoors exposed to the weather and the like, it has not been possible to attach a ceramic panel to an exterior wall surface to make the exterior.

The present invention has been made in view of such a conventional situation,
To provide a ceramic panel mounting method that can maintain high mounting reliability for a long period of time by using only mechanical means to prevent the ceramic panel mounted on the wall of the frame from falling, and can be used for exterior wall of an outdoor wall. Aim.

[0009]

In order to achieve the above object, a method for mounting a ceramic panel provided by the present invention comprises:
An anchor fitting is inserted into an undercut hole drilled on the back surface of the ceramic panel, and a headless screw member is screwed into the anchor fitting to expand the diameter of the anchor portion. After engaging and holding, and fixing one end of the hanging metal fitting to the back surface of the ceramic panel by the anchor metal fitting, the other end of the hanging metal fitting is fixed to the wall surface of the skeleton with a fixing metal fitting, and The ceramic panel is bonded and fixed to the wall surface with an elastic adhesive partially applied to the back surface.

The anchor fitting used in the method of mounting a ceramic panel according to the present invention has a plurality of slits extending in the axial direction from a tip end protruding portion, and an anchor portion which is expanded in diameter by screwing a screw, and the anchor portion. And a nut portion provided on the opposite side to the tip projecting portion.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, as a method for attaching a ceramic panel to a wall surface, a means for preventing mechanical drop without using any adhesive is employed in addition to fixing with an elastic adhesive. That is, by fixing one end of the hanging metal fitting having the other end fixed to the wall surface to the anchor metal fitting engaged with the back surface of the ceramic panel, the ceramic panel is prevented from dropping.

Further, the anchor used has a plurality of slits extending in the axial direction from the projecting end portion, usually four slits, and is provided with an anchor portion which is enlarged in diameter by screwing. By expanding the diameter of the anchor portion, it is possible to engage and hold the distal end protruding portion of the expanded anchor portion with the anchor cut hole formed on the back surface of the ceramic panel previously drilled. For this reason, when attaching the anchor, no extra force is applied to the ceramic panel, and cracking or breakage of the ceramic panel can be prevented.

[0013] In addition, by using a headless screw member instead of a normal hexagonal bolt as a screw for expanding the diameter of the anchor portion of the anchor fitting, the protruding portion from the rear surface of the ceramic panel can be extremely reduced. it can. Thereby, the gap between the back surface of the ceramic panel and the wall surface of the skeleton can be made extremely small, specifically, about 4 to 5 mm. In addition, a headless screw member has a shape without a hexagonal head of a normal hexagonal bolt, and is generally referred to as a set screw in this technical field. Set screws and slotted set screws are equivalent.

After the ceramic panels are sequentially attached to the wall surface by the elastic adhesive and the mechanical drop-preventing means as described above, the gap between the plurality of ceramic panels is sealed with the joint material to form the exterior wall surface. The ceramic panel and the elastic adhesive used in the present invention are not particularly limited,
It may be the same as the conventional one.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for mounting a ceramic panel according to the present invention will be described in more detail with reference to the drawings. First, Figure 1
As shown in FIG. 3, an undercut hole 12a having a bottom hole diameter larger than the inlet hole diameter is formed on the back surface of the ceramic panel 12, and then the anchor portion 13a is expanded in the undercut hole 12a. The resulting anchor 13 is inserted. At this time, the anchor portion 13a of the anchor 13
Is inserted into a hole provided at one end of the hanging bracket 15, so that the elongated plate-shaped hanging bracket 15 is attached to the ceramic panel 1.
2 with the back surface.

As shown in FIGS. 2 and 3, the anchor 13 has a substantially cylindrical shape as a whole.
a is provided with a leading end protruding portion 13d on the front end side and a nut portion 13c on the rear end side. The anchor portion 13a has four slits 1 extending in the axial direction from the tip protrusion 13d.
2B, the diameter of the front end side is smaller than that of the rear end side as shown in FIG. 2, but the diameter of the anchor portion 13a is increased by the screwing of a screw such as the headless screw member 14. I have.

When a screw, for example, a headless screw member 14 according to the present invention is screwed into the anchor fitting 13 from the nut portion 13c, the nut portion 13a is moved as the headless screw member 14 enters as shown in FIG. Expand the diameter. As a result, a tip projecting portion 13d provided at the tip of the nut portion 13a whose diameter has been increased.
Abuts on the small diameter portion on the entrance side of the undercut hole 12a, and the anchor 13 is engaged with and held by the ceramic panel 12.

In this way, the hanging metal 15 can be fixed to the back surface of the ceramic panel 12 by using only the anchor metal 13 without using an adhesive. In this state, since there is a slight gap between the anchor portion 13a and the tip projecting portion 13d of the anchor 13 and the inner peripheral surface of the undercut hole 12a, the ceramic panel 12 is cracked or damaged when the anchor 13 is attached. Never do.

As described above, the ceramic panel 12 in which the hanging metal 15 is fixed to the back surface by the anchor metal 13 is attached to the wall 1a of the frame 1 made of concrete, fire-resistant board, or the like using the fixing metal. Specifically, as shown in FIG. 1, an anchor plug 16 is previously driven into a predetermined position on a wall surface 1a of the skeleton 1, and the anchor plug 16
The screw 17 is fitted through a hole provided at the other end of the hanging bracket 15.

At this time, the ceramic panel 12 is
a, and is adhered and fixed to the wall surface 1a by an elastic adhesive (not shown) partially applied to the back surface. After the ceramic panels 12 are sequentially attached to the wall surface 1a of the skeleton 1 in this manner, the gaps between the plurality of ceramic panels 12 are sealed with the joint material 18 to form an exterior wall surface.

Note that the fixing bracket is the same as the anchor plug 1 described above.
The members are not limited to 6 and screws 17, and other members used for similar applications can be used. Further, it is preferable to use a material such as stainless steel which has corrosion resistance and is hard to rust, for the members such as the hanging bracket 15 and the screw 17.

An example of the anchor having the above-mentioned structure is a product (Kail system) manufactured by KEIL of Germany. However, as shown in FIG. 4, the screws used for ordinary anchors, including the above-mentioned Kyle system, are generally hexagonal bolts 19 having a hexagonal head 19a. Are screwed into each other, so that the distance between the back surface of the ceramic panel 12 and the wall surface is 10
mm or more.

On the other hand, in the present invention, FIGS.
Since the headless screw member 14 is used as shown in FIG. 3, the gap between the back surface of the ceramic panel 12 and the wall surface of the skeleton is 4 to 5 m.
m or much less. Accordingly, it is possible to reduce the protrusion of the exterior surface from the wall surface of the skeleton, and it is possible to reduce the amount of the elastic adhesive used for bonding the ceramic panel 12 to the wall surface as compared with the conventional case, which is economically advantageous. .

[0024]

According to the present invention, when the interior and exterior ceramic panels are mounted on the wall surface of the skeleton, the ceramic panels are adhered and fixed to the wall surface with an elastic adhesive, and at the same time, the ceramic panel is hung on the wall surface by mechanical means to be dropped. Prevents the ceramic panel from hanging over a long period of time, and can also be used for exterior wall surfaces exposed to the elements such as wind and rain. Can be provided.

Further, by using a headless screw member to expand the diameter of the anchor portion of the anchor, the protruding portion from the rear surface of the ceramic panel can be extremely reduced to about 4 to 5 mm. The protrusion of the panel exterior surface can be reduced, and the amount of the elastic adhesive for bonding the ceramic panel to the wall surface can be reduced as compared with the conventional case, which is economically advantageous.
