Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for exterior materials such as roofing materials of buildings.

[Prior art]

Conventionally, as a mounting structure for exterior materials such as roofing materials, a support metal fitting including a support metal body having a trapezoidal part and a locking plate formed by cutting and raising the sloped plates on both sides of the support metal body is used for mounting on a main building, etc. the trapezoidal groove-shaped portion of the architectural exterior material is pressed into the support member, and
It is known that a locking step provided on the inclined side plate of the trapezoidal groove portion is engaged with the tip of the locking plate of the support fitting (see Japanese Utility Model Publication No. 56-52336).
.

However, in the case of the conventional exterior material mounting structure, when the thickness of the exterior material is increased, a considerably large pushing force is required to push the trapezoidal groove-shaped portion of the exterior material into the support fitting and expand and deform it. However, there is a problem in that it is difficult to install the exterior material.

・[Objective and structure of the invention] The purpose of the present invention is to provide a structure for attaching architectural exterior materials that can advantageously solve the above-mentioned problems. A support metal fitting 4 comprising a support metal body 1 having a structure and locking plates 3 protruding from slope plates 2 on both sides of the support metal body 1.
is fixed to the support member 5, the trapezoidal groove-shaped portion of the exterior material 6 is fitted into the trapezoidal portion of the support metal fitting 4, and the locking step portion 8 provided on the inclined side plate 7 of the exterior material 6 is fixed to the support member 5. In the exterior material mounting structure that is engaged with the tip of the locking plate B of the support fitting 4, the top plate of the exterior material O is formed into a stepped obtuse V-shape, and the center part of the top plate is attached to the support metal fitting 4. Architectural exterior material installation characterized in that the locking step 8 of the inclined side plate 7 is pressed against the tip of the locking plate groove of the support fitting 4 by being pressed directly or indirectly against the top of the support fitting 4. It's in the structure.

〔Example〕

Next, the present invention will be explained in detail using illustrated examples.

FIG. 4 shows an exterior roofing material 6 used in an embodiment of the present invention, in which top plates 10A and 10B have an obtuse-angled 7-shaped cross section, and each inclined side plate of a metal trapezoidal corrugated plate having an IOC. A locking step 8 extending parallel to the top plate is bent at the middle part of the trapezoidal corrugated plate in the width direction, and an inclined side plate is bent at the outer end of the top plate 10B at one end in the width direction of the trapezoidal corrugated plate. The outer end of the top plate 10B is the terminal end, and a short inclined side plate 7A is provided at the outer end of the top plate 10C at the other end in the width direction of the trapezoidal corrugated plate.
A locking step 8 protruding toward the inclined side plate 7 and a draining ridge 11 are successively arranged.

5 and 6 show a support fitting 4 used in an embodiment of the present invention, in which a top plate 9 of a support fitting main body 1 made of a trapezoidal corrugated metal tight frame is shown.
The upper plate 1 of a trapezoidal locking fitting 12 with a downward opening is placed on the upper surface and fixed by spot welding or the like. The opening angle θ1 is larger than the opening angle θ1 of the inclined plates 2 on both sides of the downwardly opening trapezoidal portion of the fitting body 1.

1 to 6 show the exterior material 6 constructed as described above.
, 6A and a support fitting 4 according to an embodiment of the present invention, in which the bottom plate of the support fitting 4 is brought into contact with a support member 5 such as a main house and fixed by welding or the like. The trapezoidal groove-shaped part opening downward at the middle part of the exterior material B is pushed into the support fitting 4, and the locking plate holder is pressed by the inclined side plates 7 on both sides of the trapezoidal groove-shaped part. The locking plate 6 is bent and deformed from the position shown by the solid line to the position shown by the chain line in FIG. The locking steps 8 of the inclined side plates 7 on both sides of the part are pressed together, and the top plate 1 of the intermediate part of the exterior material B
The center portion of 0A is directly elastically pressed against the top of the support fitting 4, that is, the upper plate 16.

The locking step 8 on the inclined side plate 7 at one end in the width direction of the exterior material B is engaged with the tip of the locking plate slot on one side of the support fitting 4, and Top plate 10B
The center portion of the outer sheathing material B is in contact with the top of the support fitting 4, and the trapezoidal groove-shaped portion at the other widthwise end of the other sheathing material 6A is in contact with the top plate 10B at one widthwise end of the sheathing material B.
and is press-fitted so as to cover the upper part of the inclined side plate 7, and the locking step 8 of the sloped side plate 7 at the other end of the other exterior member 6A in the At the same time, the locking step 8 of the short inclined side plate 7A is pressed against the locking step 8 of the inclined side plate 7 at one end in the width direction of the exterior material B, and the water draining protrusion is still in contact. The tip of the strip 11 is pressed against the inclined side plate 7, and the top plate 10C at the other end in one direction of the other exterior material 6A is pressed against the top plate 10A at one end in the width direction of the exterior material B. 1. When locking the trapezoidal groove-shaped portion at the middle part of the exterior material and the trapezoidal groove-shaped portion at the other end in the width direction of the exterior material by force-fitting, the second
As shown by the chain line in the figure, the top plate 10A, IOC is
By bending and deforming within the elastic limit so that the opening angle of the shape becomes smaller.

The opening angle of the trapezoidal groove-shaped portion in the exterior material can be easily widened, and therefore the push-fitting and locking operations can be easily performed.

When carrying out this invention, without using the locking metal fitting 12,
A locking plate may be formed by cutting and raising the inclined plate 2 of the support fitting main body 1.

〔Effect of the invention〕

According to this invention, the top plates i0A and 10C of the trapezoidal groove-shaped portion of the exterior material B which is press-fitted to the trapezoidal portion having the locking plate 6 of the support fitting 4 are formed to have an obtuse V-shaped cross section. Therefore, the top plate 10A, IOC is at an obtuse angle V
It can be easily bent and deformed in the direction where the opening angle of the letter shape becomes smaller, and by bending and deforming in such a way, the opening angle of the trapezoidal groove portion in the exterior material B can be easily enlarged. It is possible to easily push and fit the trapezoidal groove-shaped portion of the exterior material B to the support metal fitting 4 having the locking plate 6, and furthermore, the central portion of the top plates 10A and 10C having an obtuse V-shaped cross section can be supported by the metal fitting. 4
When the top plates 10A and 10C are pressed and deformed so that their obtuse opening angles are expanded while they are supported directly or indirectly on the top of the exterior material B, the opening angle of the trapezoidal groove portion of the exterior material The top plate 10A tends to shrink and has an obtuse V-shape.
.

The locking stepped portion 8 of the inclined side plate 7 due to the elastic restoring force of 10C
is pressed against the tip of the locking plate in the support fitting 4, so that the exterior material 6 can be mounted in a stable state without wobbling or coming off.
