It is attached to the structural frame via. In FIGS. 18 to 21, a trunk edge is shown as the base material 8.

As shown in FIGS. 17 to 21, the fastener 9 is provided with a substrate portion 91 which is in contact with the rear side surface 26 of the upper and lower outer wall plates 2, and is provided upright from the substrate portion 91. It has a support portion 92, an upper plate locking portion 93 bent obliquely upward from the support portion 92, and a lower plate locking portion 94 bent diagonally downward from the support portion 92. A front flat plate portion 934 is formed in front of the upper plate locking portion 93 and the lower plate locking portion 94 in contact with the upper back surface 226 of the lower wall of the upper outer wall plate 2. The board portion 91 has a nail hole 9 for inserting a nail 41 and a screw 42 for fixing the fastener 9 to the structural frame via the base material 8.
8 and a screw hole 99.

Further, as shown in FIG. 17, the substrate portion 91 has a slope portion 91 which retreats obliquely rearward at an upper portion thereof.
1 and a lower leg 912 bent at the lower end substantially 90 ° rearward. Between the inclined surface portion 911 and the lower leg portion 912, there is provided a central plate portion 913 for connecting these and at the same time abutting on the back side surface 26 of the outer wall plate 2. The support portion 92 is provided upright on the central plate portion 913. The nail hole 98 is formed in the slope portion 911, and the screw hole 99 is formed in the center plate portion 913 between the slope portion 911 and the support portion 92.

[0005] In fixing the fastener 9 to the structural frame through the base material 8, a nail 41 or a screw 42 is used.
Is fixed to the structural body via the base material 8. That is,
When the nail 41 is used, as shown in FIGS. 18 and 19, the nail 41 is inserted into the nail hole 98 and is slanted downward and is struck toward the structural body through the base material 8 to thereby secure the nail. The metal fitting 9 is fixed to the structural body.

When the screw 42 is used, as shown in FIGS. 20 and 21, the screw 42 is inserted into the screw hole 99 and screwed into the structural body through the base material 8 to form the screw. The fastening metal 9 is fixed to the structural body via the base material 8. Thus, the fastening 9

8, FIG. 19) and fixing with screws 42 (FIGS. 20, 21).
Are configured so that the installer can freely select them.

[0007]

However, the fastener 9 has the following problems. The fixing force of the fastener 9 to the structural frame against the load of the outer wall plate 2 and the wind pressure is as follows.
It is so large that the nail 41 and the screw 42 are arranged at a position closer to the bearing 92 that receives a load. Therefore, when the nail hole 98 and the screw hole 99 are provided at positions different from each other in the distance from the support portion 92, the fixing force with respect to the load or the wind pressure is not fixed by the nail 41 and the screw 42. Will be different.

In the fastener 9, the nail hole 98 is formed in the slope portion 911, and the screw hole 99 is formed in the center plate portion 913 (FIG. 17). That is,
The nail hole 98 is larger in the bearing 92 than the screw hole 99.
Located away from Therefore, the fixing force when fixing with the nail 41 (FIGS. 18 and 19) is smaller than the fixing force when fixing with the screw 42 (FIGS. 20 and 21).

For this reason, in the outer wall construction structure 90 using the above-mentioned fastener 9, the above-mentioned fastener 9 is fixed to the structural body via the base material 8 with the nail 41,
There is a difference in the fastening force of the outer wall plate 2 to the structural frame between the case where the outer wall plate 2 is fixed with the screw 42. As a result, the wind resistance and the like differ depending on the fixing means of the fastener 9.

[0010] Therefore, in one building, it is necessary to unify any of the fixing means so as not to cause a difference in the fastening force of the outer wall plate partially. Further, it is not always preferable that a difference occurs in the fastening force of the outer wall plate between individual buildings. Therefore, it is necessary to unify the fixing means between individual buildings.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a fastening device which does not cause a difference in fastening force of an outer wall plate due to a difference in fixing means to a structural body, and an outer wall using the same. It is intended to provide a construction structure, a starter fitting, and a method for constructing an outer wall.

[0012]

According to a first aspect of the present invention, there is provided a structure of a building which is disposed over an upper side of a lower outer wall plate and a lower side of an upper outer wall plate, and connects the outer wall plate with a base material. A fastener for attaching to a frame, wherein the fastener includes a board portion abutting on the back side surface of an outer wall plate arranged vertically, a support portion erected forward from the board portion, and the support portion. An upper plate locking portion bent upward from the support portion, and a lower plate locking portion bent downward from the support portion, wherein the board portion includes a nail and a nail for fixing the fastener to the structural frame. A fastener having a nail hole and a screw hole for inserting screws, and the nail hole and the screw hole are provided at positions where the distance from the bearing is equal. It is in.

The most remarkable point in the present invention is that the nail hole and the screw hole are provided at positions where the distance from the bearing is equal. That is, a vertical distance A from the center plane of the bearing to the nail hole is substantially equal to a vertical distance B from the center plane of the bearing to the screw hole (see FIG. 2B). With respect to the fastener itself, the side where the nail hole is provided with respect to the position of the bearing is defined as “upper”, and the opposite side is defined as “lower”, and the name of each part is defined. Do.

The screw hole is formed on the opposite side of the nail hole. That is, since the screw hole is provided below the support portion, when fixing with the screw, it is necessary to reverse the direction of the fastener. In this case, the upper plate locking portion locks the lower outer wall plate, and the lower plate locking portion locks the upper outer wall plate (see FIG. 6). Thus, the positional relationship between the nail and the screw with respect to the support portion is the same when using the nail and when using the screw.

Next, the operation and effect of the present invention will be described.
In the fastener, as described above, the nail hole and the screw hole are provided at positions where the distance from the support portion is equal. For this reason, there is no difference in the fixing force against the load and wind pressure of the upper outer wall plate between the case where the fastener is fixed with a nail and the case where the fastener is fixed with a screw.

For this reason, no difference occurs in the fastening force of the outer wall plate even when the outer wall construction structure is formed by fixing the fastener using either a nail or a screw. That is, there is no possibility that a problem such as floating or falling off of the outer wall plate is caused by changing the fixing means of the fastener. For example, the wind resistance performance and the like of the outer wall construction structure do not differ depending on the fixing means of the fastener. In addition, the above-mentioned fastener is a fixing means, that is, whether to use nails or screws.
Construction is easy because the constructor can freely select according to various conditions at the time of construction.

As described above, according to the present invention, it is possible to provide a fastener that does not cause a difference in the fastening force of the outer wall plate due to a difference in the fixing means to the structural body.

Next, as in the second aspect of the present invention, the substrate portion has an upper contact portion and a lower contact portion which contact the base material at upper and lower portions thereof, and the upper contact portion and the lower contact portion. An upper rising portion and a lower rising portion formed to rise forward from the lower contact portion, respectively, and a central plate connecting between the upper rising portion and the lower rising portion and abutting against the back side surface of the outer wall plate. And the support portion is preferably provided upright on the central plate portion.

Thus, the outer wall plate can be attached to the structural frame by providing a gap between the back side surface of the outer wall plate and the base material. Therefore, a ventilation layer is formed between the outer wall plate and the base material, and the durability of the outer wall construction structure is improved.

Next, as in the third aspect of the present invention, it is preferable that the upper rising portion and the lower rising portion have a horizontal surface portion substantially perpendicular to the central plate portion. As a result, it is possible to obtain a fastener that can be easily installed.

When fixing the fastener to the structural body, the fastener is first engaged with the lower outer wall plate. That is, the upper side portion of the lower outer wall plate is fitted between the base plate portion, the support portion, and the lower plate engaging portion of the fastener.

Thus, the nail can be inserted into the nail hole and hit obliquely downward against the structural body via the base material. Therefore, the fastener can be securely fixed to the structural skeleton and can be securely locked to the lower outer wall plate.

Next, as in the sixth aspect of the present invention, it is preferable that the upper contact portion and the lower contact portion have contact surfaces substantially parallel to the central plate portion (see FIGS. 1 and 2). 11). Accordingly, the contact area between the upper contact portion and the lower contact portion and the base material can be increased, and the upper contact portion and the lower contact portion can be prevented from biting into the base material. That is, even when the base material is made of a soft material such as a foamed resin plate, the upper contact portion and the lower contact portion of the fastener do not bite into the base material, and the base material is fastened. It is possible to prevent the metal fitting from sinking into the base material. Therefore, the outer wall plate can be stably fastened to the structural frame via the base material.

An outer wall construction method characterized by the following.

The most remarkable point of the outer wall construction method is that, in the first step and the third step, when the fastener is fixed by using a nail, the nail hole is arranged above the supporting portion. However, when fixing with screws, the screw hole should be arranged above the bearing.

Therefore, when the screw hole is provided below the support portion, that is, on the opposite side of the nail hole, when the screw is fixed, the fastening metal is not used. You need to turn it upside down. In this case, the upper plate locking portion locks the lower outer wall plate, and the lower plate locking portion locks the upper outer wall plate.

With this arrangement, the positional relationship between the nail and the screw with respect to the support portion can be made equal between the case where the nail is used and the case where the screw is used, so that the fixing force of the fastener to the structural frame is changed. Absent. Therefore, according to the above outer wall construction method, it is possible to construct an outer wall construction structure in which there is no difference in the fastening force of the outer wall plate due to the difference in the fixing means to the structural frame.
