[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior material mounting metal fitting suitable for an outer insulation method for an outer wall.

[0002]

2. Description of the Related Art Conventionally, in this type, the outer insulation method for the outer wall is rarely used, and most of the inner insulation methods are used when no heat insulating material is used. In the method of attaching the exterior material to the outer wall such as reinforced concrete construction, PC concrete construction, ALC construction, extruded cement molding board construction, etc., when the heat insulating material is not used, or in the inner heat insulation construction method, the attachment method of tiles etc. One method) is implemented as shown in FIG. In the figure, 11 is reinforced concrete, 11A is mortar, and 11B is tile.

Further, in the case of metal siding, ceramic siding, etc., the method (second method) which is usually carried out is shown in FIG.

[0005]

If external heat insulation is used,
The following problems arise. That is, the skeleton and the exterior material are fixed by the fittings that connect them, but in the external heat insulation method, compared with the case where there is no heat insulating material due to the heat insulation layer, the skeleton side is reinforced concrete, PC concrete, ALC The distance to the exterior material increases.
That is, if there is no insulation on the outside of the outer wall, the tile,
The exterior panel can be easily attached, but in the case of the external insulation method, the exterior material must be fixed to the outside of the heat insulating material, which complicates the attachment method.

In addition to its own weight, the exterior material is subjected to wind pressure load, seismic force, etc., and the total load thereof is applied to the body through the mounting hardware. If the distance between the exterior material and the skeleton increases, the moment force applied to the part (anchor bolt part) connected to the skeleton of the mounting metal increases in proportion to it, and to cope with this, the size of that part is increased or It is necessary to increase the number of connecting parts. An increase in size or increase in quantity leads to a so-called heat bridge, which leads to an increase in heat dissipation, which is not desirable in terms of energy saving.
In addition, the number of mounting steps is increased, which is not economically preferable.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide the following things. It is proposed that the effect of external heat insulation is surely exhibited and that mounting of the exterior material is accurately and easily performed. 1. Regardless of the distance between the body and the exterior material, the weight of the exterior material is received only by the shearing force. (A small member is all right.) 2. The mounting portion of the exterior material serves as a retainer for the heat insulating material, and the ventilation layer is secured. 3. Level adjustment can be done with screws.

In the case of the present application, in the rectangular tubular exterior material mounting vertical frame 4 to be supported in parallel with the wall surface portion 2A of the frame at a desired interval, the exterior material mounting vertical frame 4 corresponds to the wall surface portion 2A of the frame. An appropriate number of grip anchors 5 arranged vertically, a support rod 6 screwed into the grip anchors, and a root nut 7 screwed into the root portion of the support rod 6. An outer nut 8 having a pair of an inner nut body 8A and an outer nut body 8B screwed to the tip portion of the support rod 6 and an outer nut 8 at the tip portion of the support rod 6 are used for the exterior material. The mounting vertical frame 4 is connected and supported, and the reinforcing portion 9 is provided in an inclined state between the mounting portion of the root nut 7 of the grip anchor 5 and the position below the mounting portion of the outer nut 8 of the exterior material mounting vertical frame 4. It is an exterior material mounting bracket that is suspended.

In this case, it can be configured as follows. The reinforcing portion 9 includes an inclined plate 9A having a predetermined width,
A vertical plate 9B which is vertically connected to the upper end of the inclined plate,
A circular hole 9B1 opened in the center of the vertical plate and a holding frame 9C for vertically connecting the external material to the vertical end of the inclined plate.
It consists of and. Further, the support rod 6 is inserted into the circular hole 9B1 in the reinforcing portion 9 and is crimped to the grip anchor 5 with the root nut 7, and the holding frame 9C holds the exterior material mounting vertical frame from the inside. It can be fixed with the pierce screw 9C1.

Further, a circular hole 4A1 into which the tip portion of the support rod 6 can penetrate is formed in the inner surface 4A of the exterior material mounting vertical frame 4, and an outer nut 8 is provided on the outer surface 4B of the exterior material mounting vertical frame 4. A circular hole 4B1 for operating the outer nut body 8B from the outside is opened in advance, and the outer nut body 8B in the outer nut 8 is removed from the tip portion of the support rod 6,
After the support rod 6 is inserted into the circular hole 4A1 in a state where the inner nut body 8A is located on the inner surface of the exterior material mounting vertical frame 4, the outer nut body 8B can be tightened from the outside. In addition, the vertical frame for mounting the exterior material can be configured to have a U-shaped cross section or a C-shaped cross section.

EXAMPLES Examples will be described with reference to the drawings. 1
Is an exterior material mounting bracket of the present invention. Reference numeral 2 is a frame to which the exterior material 3 is attached by the exterior material mounting bracket 1. Therefore, the exterior material mounting bracket 1 is a rectangular tube-shaped exterior material mounting vertical frame 4 which is to be supported in parallel with the wall surface portion 2A of the body at a desired interval, and the exterior material mounting vertical frame is attached to the wall surface portion 2A of the body. 4, a proper number of grip anchors 5 which are installed vertically, a support rod 6 screwed into this grip anchor, and a base screwed to the root of the support rod 6. The nut for use 7, the outer nut 8 having a pair of inner nut body 8A and outer nut body 8B screwed to the tip portion of the support rod 6, and the outer nut 8 for the tip portion of the support rod 6 are used. The exterior material mounting vertical frame 4 is connected and supported.

Reference numeral 9 denotes a reinforcing portion which is suspended in an inclined state between a mounting portion of the root nut 7 of the grip anchor 5 and a position below the mounting portion of the outer nut 8 of the exterior material mounting vertical frame 4. . The reinforcing portion 9 includes an inclined plate 9A having a predetermined width, a vertical plate 9B vertically connected to the upper end of the inclined plate, and a circular hole 9 formed at the center of the vertical plate.
B1 and a sandwiching frame 9C that is vertically connected to the lower end of the inclined plate and is sandwiched by a vertical frame for mounting the exterior material.

The holding frame 9C is formed in a U-shape in a plane outward shape so that the vertical frame 4 for mounting the exterior material can be held from the inside. Therefore, the support rod 6 is provided in the circular hole 9B1 in the reinforcing portion 9.
Is penetrated and crimped to the grip anchor 5 by the root nut 7, and the holding frame 9C is fixed by the pierce screw 9C1 in a state where the vertical frame for mounting the exterior material is held from the inside.

Next, the connection state between the tip portion of the support rod 6 and the exterior material mounting vertical frame 4 will be described. A circular hole 4A1 through which the tip portion of the support rod 6 can penetrate is formed in the inner surface 4A of the exterior material mounting vertical frame 4, and the outer nut body 8B of the outer nut 8 is formed on the outer surface 4B of the exterior material mounting vertical frame 4. A circular hole 4B1 for operating from the outside is opened. Therefore, the outer nut body 8B of the outer nut 8 is removed from the tip portion of the support rod 6, and the inner nut body 8A is used as the exterior material mounting vertical frame 4.
After the support rod 6 is inserted into the circular hole 4A1 in a state of being located on the inner surface of the above, the outer nut body 8B is tightened from the outside.
Since only the shearing stress is applied to the support rod 6 and the bending moment force related to the distance between the skeleton and the exterior material is not applied, it suffices to consider only the thickness capable of withstanding the shearing stress.

The exterior material mounting vertical frame 4 can be constructed as follows. First, as shown in FIG. 3, the exterior material mounting vertical frame 41 having a U-shaped cross section can be formed. Further, as shown in FIG. 4, the exterior material mounting vertical frame 42 having a C-shaped cross section can be configured.

The exterior material mounting vertical frame 4 has a function of crimping and fixing the heat insulating material 10, and serves as a base material for fixing the exterior material with screws or the like. By rotating the inner nut body 8A, the level of the exterior material mounting vertical frame 4 can be easily adjusted.
The surface on the inner side of the exterior material mounting vertical frame 4 is crimped with the heat insulating material 10,
By attaching the exterior material to the outer surface, the thickness of this member becomes an air layer. The exterior material mounting vertical frame 4 is installed in the vertical direction so that the air in the air layer is heated to generate buoyancy, which prevents ventilation by draft force.

The operation will be described together with the effect.

[0018]

Since the present invention is configured as described above, it has the following effects. 1. The joint between the vertical frame 4 for mounting the exterior material and the skeleton applies only shear stress to the support rod and tensile stress to the reinforcing portion 9, and requires only a small member regardless of the size of the heat insulating layer. (The heat insulation effect is great.) 2. Easy level adjustment, beautiful finish and efficient construction. 3. In the external heat insulation method, the heat insulation material is accurately adhered to the body,
The ventilation layer can be removed surely and the correct construction method can be ensured.
