Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a fixing structure for a building cover and an adherend used for an outer wall, an inner wall or a ceiling of a building.

<Prior art> For the material of the exterior material such as the outer wall, the inner wall or the ceiling of the building,
Considering disasters such as fires and earthquakes, there are crystallized glass, pottery, magnetism, marble, etc. that have excellent heat resistance, water resistance, and durability. When mechanical stress is applied, there is a risk that the entire surface covering material and fixed parts will be damaged and fall. So as a preventive method,
At present, organic, inorganic or natural fibrous nets and mats are attached to the back surface of the facing material.

To attach the cover material to the base material, hook the insert metal fitting provided on the back surface of the cover material to the clamp metal fitting attached to the concave portion of the base material, and bond the bead-shaped adhesive to the gap between the base material and the cover material. The agent was applied and each was fixed.

<Problems to be solved by the invention> As described above, in the past, a fibrous net was attached to the back surface of the surface covering material as a reinforcing material together with an adhesive. Since the adhesive itself has high rigidity, the adhesive layer also cracks together with the covering material, and the net is also directly stressed with it, causing the fragments of the covering material to drop to the ground. And very dangerous.

The present invention was made by focusing on the above problems,
Its purpose is to prevent damage to the surface material when external stress is applied to the surface material due to an earthquake, etc., or to prevent the fragments from falling even if it is damaged. It is intended to provide a fixed structure for building exterior materials that effectively absorbs vibration.

<Means for Solving the Problems> The present invention has been made in view of the above object, and its gist is to provide a fixing structure for a building covering material for fixing a covering material to an adherend. However, as well as disposing a mounting metal fitting at a required position on the back surface of the covering material, an attachment reinforcing material,
An elastic adhesive that expands and contracts following the attached reinforcing material is integrally attached to the back surface, and the mounting metal fitting is hooked on a receiving metal fitting provided on the adherend with play, and The fixing structure for a building covering material is configured by sticking a moisture-curable elastic adhesive to a predetermined space between the covering material and the adherend. Here, the elastic adhesive is represented by, for example, Cemedine Co., Ltd. PM100, PM200, PM210, elastic adhesive based on modified silicone oligomer such as POS seal, elastic coating agent and elastic sealing material. However, as seen in elastic adhesives such as epoxies, polyurethanes, polybutadienes, polysulfides, etc., elastic coating agents, elastic sealing materials, etc., those that bond the respective adhesive parts after adhesion in an elastic state are included. Further, as the above-mentioned attachment reinforcing material, for example, metal, glass, synthetic resin, natural material, fiber made of carbon, net or the like can be selected according to application conditions.

<Operation> The building surface covering material of the present invention having the above-described structure is integrally attached to the back surface of the surface covering material together with the adhesive reinforcing material such as the elastic adhesive, the elastic coating agent, and the elastic sealing material. As a result, the attachment reinforcing material using a rigid adhesive will not be cut at the same time as the cracking of the covering material even when a large external force such as an earthquake occurs, and even if a crack occurs in the covering material, it will be elastic. Since the adhesive can expand and contract following the attached reinforcing material, it is possible to prevent the cut pieces of the covering material from falling.

Further, in the present invention, a play is provided between the mounting member and the receiving member, and a moisture-curable elastic adhesive is interposed in the gap between the cover material and the adherend, and as described above, it is simply used for the building cover material. Not only protection but also deviation due to vibration between the adherend and the covering material can be absorbed by the play and expansion / contraction state of the moisture-curable elastic adhesive.

<Embodiment> An embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a plan view showing the back surface of a building cover material according to the present invention, FIG. 2 is a perspective view of a mounting bracket arranged on the back surface of the cover member, and FIG. FIG. 4 is a partially cutaway perspective view showing the application position of the bead-shaped moisture-curable elastic adhesive on the base material as an adherend, and FIG. 4 is a vertical cross-sectional view showing the joined state of the base material and the covering material.

In FIG. 1, mounting hardware 3 is attached to the back surface 2 of a rectangular plate-shaped outer covering material 1 at four locations around the outer covering material 1, and the back surface 2 excluding this portion has an attached reinforcing material. The reinforcing portion 6 in which the fibrous net 4 and the elastic adhesive 5 such as an elastic adhesive, an elastic coating agent, or an elastic sealing material are integrated is attached to the entire surface.

As shown in FIG. 2, in the mounting bracket 3, screw pins 9 are screwed into channel-shaped screw holes 10 of the left and right main bodies, and by tightening these screws, the left and right main bodies 8 and 8 come close to each other, and It can be fastened and fixed in the vertical groove 16 on the back surface. Further, a hook-shaped hook member 7 is loosely fitted on the screw pin 9 so that a play is generated left and right in the gap between the left and right main bodies 8, 8. Therefore, when the hook member 7 is hooked and fixed to the receiving member 13 of the adherend described later, the mounting metal member 3 has a height H of the hanging groove 11 of the hook member 7 against vertical shaking such as an earthquake. In addition, there is a margin for the shaking in the left-right direction by the width of the play.

In FIG. 3, the receiving metal fitting 13 provided in the concave portion of the long base material 12 having an E-shaped vertical section is a crank-shaped metal fitting and is arranged at a position corresponding to the mounting metal fitting 3 of the above-mentioned mounting material 1 and fixed by a fixing pin 14. is doing. Also, on the convex portion of the base material 12, the surface material 1
Before fixing, the moisture-curable elastic adhesive 15 is applied in a bead shape at a predetermined interval. In addition, on the right side of FIG. 3, the covering material 1 is fixed to the base material 12.

FIG. 4 is a sectional view taken along line AA in FIG.
The receiving metal fitting 13 provided on the above and the mounting metal fitting 3 attached to the back surface of the facing material 1 are hooked. Further, between the base material 12 and the facing material 1, the moisture-curable elastic adhesive 15 is adhered,
It is designed to be able to expand and contract following bending or shear stress.

<Effect> According to the present invention, by adhering together an attachment reinforcing material and an elastic adhesive that expands and contracts with the attachment reinforcing material on the back surface of the building covering material, a crack may occur in the exterior material. Even if there is a crack, the adhesive layer does not crack at the same time as in the conventional case, and the entire back surface of the covering material can be held by both the attached reinforcing material and the elastic adhesive, which has been cut. It is possible to prevent the fragments of the covering material from falling.

In addition, the mounting bracket fixed to the cover material and the receiving bracket fixed to the adherend are hooked with play, and the cover material and the adherend are elastically joined by a moisture-curing elastic adhesive. Since the structure is adopted, the vibration can be absorbed by the play between the metal fittings and the elastic force of the elastic adhesive even when the adherend vibrates greatly (violently) due to an earthquake or the like. Therefore, according to the present invention, it is possible to provide a fixing structure having excellent earthquake resistance as compared with the conventional joining structure using an adhesive having high rigidity as a whole.
