Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fastener for an outer wall material.

[0002]

2. Description of the Related Art Conventionally, there is a case where a metal fitting 2 as shown in FIG. 6 is used as a means for fastening a ceramic outer wall material 1 such as a fiber reinforced cement outer wall material. This fastener 2
Engaging piece 2 engaging with end face of outer wall material 1 to be joined to substrate 2a
b and 2b are formed by bending, and a nail is
It is fixed with fasteners 4 such as screws, and then the engagement pieces 2
b and 2b are fixed so that the end face 1a of the outer wall material 1 is hooked.

[0003] The metal fitting 2 shown in FIG.
It is desirable that the engagement piece 2b and the end surface 1a of the outer wall material be in close contact with each other when the first member is fixed. Therefore, when the metal fitting 2 is fastened, the metal fitting 2 is fixed as much as possible in the direction of the previously fixed outer wall material 1 (the left outer wall material in the illustrated example). In particular, the metal fittings 2 may shift and move due to the tightening force at the time of the final retightening, and as a result, the fixing force of the outer wall material may be loosened.

[0004]

According to the present invention, as described above, the fastener of the outer wall material is surely moved in the tightening direction when the fastener such as a nail or a screw is tightened. It was made to be able to be fixed to the subject.

[0005]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, there is provided a fastener for an outer wall material, wherein the fastener for a through-hole for a fastener formed in a substrate fixed to a wall base surface. An inner surface interval opposed to the fastener is a tapered inclined surface, and a minimum interval portion of the inclined surface is larger than a diameter of a shaft portion of the fastener.
The maximum spacing portion is larger than the minimum spacing portion and smaller than the head diameter of the fastener, and the minimum spacing portion is oriented in the direction in which the substrate tightens.

According to the fastener of the outer wall material, when the fastener is tightened in the fastener through hole, the fastener is formed by the engagement angle between the tapered inner surface profile and the fastener. Since it moves in the engaging direction of the outer wall material, the metal fitting does not loosen during retightening. According to a second aspect of the present invention, there is provided a fastener for an outer wall material, wherein a contour of a through hole for a fastener in the fastener for an outer wall material is oval, and a small diameter portion of the oval is larger than a diameter of a shaft portion of a screw. The large diameter part is larger than the diameter of the small diameter part and smaller than the head diameter of the fastener, and the small diameter part is configured to face the direction in which the substrate tightens.

According to the fastener of the outer wall material, if the fastener is tightened in the oval-shaped fastener through-hole, the fastening angle is determined by the engagement angle between the egg-shaped contour and the fastener. Moves in the direction of engagement of the outer wall material, so that the metal fitting does not loosen during retightening. According to a third aspect of the present invention, the outer wall member is formed by folding up a nail for engaging an end surface of the outer wall member with a substrate.

[0008] In the case of the fastener of the outer wall material, since the claw piece is securely engaged with the end face of the outer wall material, the fastening strength is also ensured.

[0009]

Next, an embodiment of the present invention will be described.
FIG. 1 is a perspective view of a fastener for an outer wall material according to an embodiment of the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a plan view showing another configuration example. In FIG. 1, the fastener 10 of the outer wall material is
The inner surface contour shape of the through hole 12 of the fastener 4 formed in the substrate 11 fixed to the wall base surface 3 such as a pillar, a girder, or a rim as shown in FIG. The interval is a tapered inclined surface, the tapered minimum interval portion 12a is larger than the diameter r of the shaft portion 4a of the fastener 4 such as a nail or a screw, and the maximum interval portion 12b is the small diameter as shown in FIG. Larger than the diameter r of the portion 12a and smaller than the diameter R of the head 4b of the fastener 4;
Further, the minimum interval portion 12a of the through hole 12 is
It is drilled in the direction of the tightness of 1.

Here, the tightening direction is a direction indicated by an arrow A such that the engaging piece 13 erected on the substrate 11 is pressed against the outer wall material 1 and has a fastening function as a metal fitting. It means the direction of movement. In the drawing, reference numeral 14 denotes a spacer, which is provided on the substrate 11 when a ventilation space is provided between the outer wall material 1 and the wall base material 3, and is provided as necessary.

The contour of the inner surface of the through hole 12 of the fastener 4 may be oval as shown in FIG. In this case, the oval-shaped small diameter portion 12a is larger than the diameter r of the shaft portion 4a of the fastener 4 such as a nail or a screw, and the large diameter portion 12b is smaller than the small diameter portion 12a.
Is smaller than the diameter R of the head 4b of the fastener 4 and the small diameter portion 12a of the through hole 12 for the fastener is
The board 11 is formed so as to face in the tightening direction.

In the above-described embodiment, the case where the engagement piece 13 is bent and formed on the flat substrate 11 is shown as the metal fitting in the above-described embodiment, but as shown in FIG.
The same can be applied to the case of In FIG. 4, members denoted by the same reference numerals as those in FIGS. 1 and 3 indicate the same or corresponding members, and detailed description of these members will be omitted. Further, the material of the fastener 10 of the outer wall material is mainly made of a stainless steel thin plate, a steel plate, a soft iron plate subjected to a rust-proof treatment, or an aluminum light alloy.

Next, the use state of the outer wall material fastener of the above embodiment will be described. The substrate 11 of the outer wall material fastener 10 shown in FIGS. 1 and 3 is brought into contact with the wall base surface 3 and is applied to the end of the outer wall material 1 so that the fasteners 4 such as nails and screws are inserted into the through holes 12.
Driving or screwing into Finally, nails or screws are tightened. At this time, as the fasteners 4 are driven or screwed in, the back surface of the head 4b of the fasteners 4 and the inner surface contour of the fastener through-holes 12 are determined. Are pressed against each other, as a result, a component force (arrow W) acts on the substrate 11 as shown in an enlarged view in FIG. 5, and the substrate 11 moves toward the outer wall material 1 as shown by the arrow A.

Therefore, the fastener 10 of the outer wall material is moved in the direction of the outer wall material 1 by strongly fastening the fastener 4,
It becomes a firm fastening state.

[0015]

As described above, according to the outer wall material fastener of the present invention, when the outer wall material is applied to the end of the outer wall material and fixed to the wall base material with the fastener, the force for fixing is used. As a result, the fastener moves toward the outer wall material, so that the outer wall material is securely fixed.
