BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS.
It will be described based on 9. FIG. 9 shows an outline of an overall view of the outer wall material to which armor is attached. As shown in FIG. 9, a base material (vertical furring strip) 1 is arranged on the outside of a frame (column) (not shown) installed in the vertical direction, and a nail (not shown) is provided on the outside of the base material 1. , And a plurality of outer wall members 2, 2, ... At this time, the outer wall members 2, 2, ... Are arranged so that the plates between the left and right adjacent outer wall members 2, 2 do not overlap in the vertical direction in terms of strength and the like. In addition, in consideration of strength and the like, the space between the left and right adjacent outer wall members 2 and 2 is taken into consideration in A of FIG.
As shown in the section, it is provided between the base materials 1 and 1.

FIG. 1 is an enlarged sectional view taken along the line aa 'of the portion A in FIG. As shown in Figure 1, the structure (pillar)
The base material 1 is arranged outside (not shown), and the outer wall material 2 is applied to the base material 1 by armoring. An oblique groove 2a extending obliquely upward from the opening is formed on the side surface (rear surface) of the lower end portion in the longitudinal direction of the outer wall material 2 over substantially the entire length of the outer wall material 2, and the support metal fitting 5 is fitted into the oblique groove 2a. Thus, the structure is such that the lower end portions between the plates of the left and right adjacent upper outer wall members 2, 2 are connected.
On the other hand, the upper end portion between the plates of the left and right adjacent upper outer wall materials 2 and 2 may be fitted with the fixing metal fitting 4 from above, and by doing so, the space between the plates of the left and right adjacent upper outer wall materials 2 and 2 is It can be a structure that connects

FIG. 2 shows an enlarged sectional view of the support metal fitting 5 used in FIG. 1, and FIG. 3 shows an enlarged sectional view of a support metal fitting 6 which is another embodiment of the support metal fitting 5. Support brackets 5, 6
Is a front surface portion 5a, 6a that contacts the front surface of the upper end portion of the lower outer wall material, and upper surface portions 5b, 6b that are connected rearward from the upper end of the front surface portion and that contact the upper end of the lower outer wall material.
And engaging portions 5c and 6c which are continuously provided obliquely above the upper end of the front surface portion and which engage with oblique grooves of the adjacent left and right upper outer wall members, and are continuously provided below the rear end of the upper surface portion. With the rear portions 5d and 6d that come into contact with the back surface of the upper end portion of the lower outer wall member, the support metal fitting 6 is further extended above the upper end of the front surface portion so as to be flush with the front surface portion, and the left and right adjacent upper outer walls. And a support portion 6e that abuts the back surface of the lower end portion of the material. This support portion 6e makes it possible to more firmly fix the outer wall member 2 and the support fitting 6 to each other.

FIG. 4 shows an enlarged sectional view of the fixing member 4 used in FIG. The fixing member 4 is connected to the front surface of the adjacent left and right upper outer wall members 4a, and the upper surface portion 4b connected rearward from the upper end of the front surface member and in contact with the upper ends of the left and right adjacent upper outer wall members. And a rear portion 4d continuously provided below the rear end of the upper surface portion and abutting on the back surface of the upper end portion of the left and right adjacent upper outer wall members.

To apply the armor to the outer wall material 2, first, while the lower outer wall material 2 is fixed, the supporting metal fittings 5 and 6 are fitted into the upper end portions of the lower outer wall material 2, and the left and right adjacent upper outer wall materials 2 and 2 are attached.
The left and right adjacent upper outer wall members 2 and 2 are supported so that the engaging portions 5c and 6c of the support fittings 5 and 6 are engaged with the diagonal grooves 2a of the support brackets. The fixing metal fitting 4 is attached to the upper end portion of the. In addition, the fixing bracket 4
Also, it is apparently preferable that the support fittings 5 and 6 are configured so that they are covered with the upper outer wall material 2 so as not to be exposed in a state where the armor is attached.

Further, the fixing metal fitting 4 and the supporting metal fittings 5, 6
Are rear portions 4d, 5d, 6d as shown in FIGS.
It is preferable to have diagonal portions 4f, 5f, 6f that are continuously provided from above. By doing so, it is possible to prevent the fixing metal fitting 4 and the supporting metal fittings 5 and 6 that have been once fitted from coming off during and after construction.

FIG. 8 shows an enlarged front view of the support fitting 6. In the support metal fitting 6, it is preferable that the front surface portion 6a and the support portion 6e are provided with a longitudinally continuous protrusion 6g. Further, in the support portion 6e, the left and right adjacent vertical protrusions 6g are provided.
It is preferable that a ridge 6g is continuously provided laterally so as to connect g and 6g. The ridges 6g can increase the second moment of area of the metal fitting provided, increase the resistance of the metal fitting to bending, and further suppress the lateral movement of the adjacent left and right outer wall members. It should be noted that not only the support fitting 6 but also the protrusion 5g may be provided on the front surface portion 5a of the support fitting 5, or the protrusion 4g may be provided on the front portion 4a of the fixing fitting 4.

EFFECTS OF THE INVENTION By using the metal fittings according to the present invention, in the construction structure of the outer wall material which is fixed by armor, the outer wall material in the case where the left and right adjacent outer wall material plates are arranged between the base materials The movement in the out-of-plane direction can be suppressed. Furthermore, by using a supporting metal fitting that extends above the upper end of the front surface portion and is flush with the front surface portion and has a supporting portion that abuts against the back surface of the adjacent left and right upper outer wall materials, the outer wall material and the metal fitting are more securely fixed. Can be strong.

Further, by using the metal fitting having the diagonal portion continuously provided obliquely upward from the rear portion, it is possible to prevent the once fitted metal fitting from coming off during and after construction. Furthermore, since the metal fitting is covered with the upper outer wall material, the metal fitting is not exposed and the design is excellent.

Further, by providing the metal fitting with the ridges, the resistance of the metal fitting to bending can be enhanced, and the movement of the adjacent left and right outer wall members in the out-of-plane direction can be suppressed.
