[Embodiment of the invention]

 An embodiment of a windproof metal fitting for a sash according to the present invention will be described with reference to the drawings. As shown in FIG. 1, a metal thin plate is provided with a step portion 1 having a height H according to the thickness of the stile. The top and bottom of the step are bent at different angles in different directions to provide the upper surface locking portion 2 and the lower surface locking portion 3, and one side of the lower surface locking portion (one left side for Japanese roof tiles, one right side for western roof tiles) It is bent upward at a right angle to provide the one side locking portion 4. (The figure is an example for Japanese roof tiles.)

Since the windproof metal fittings for the roof tiles are mounted by sandwiching the two roof tiles between the upper and lower roof tiles with a slight gap for fitting the matching corner notches of the two roof tiles, the thin metal plate material (0 3 to 0.5 mm). When the rigidity of the windproof metal fittings for the roof tiles decreases due to the material by using a thin plate material, as shown in FIG. The ribs 5 in two rows in the example) are provided in a protruding manner to increase the rigidity of the windproof metal fittings for the roof tiles and prevent the roof tiles from rising due to a strong wind pressure such as a typhoon.

Further, as shown in FIG. 3, the upper surface locking portion 2 of the windproof metal fitting for a sash is bent so that it is slightly more acute than a right angle, and the tip portion is bent in the opposite direction, so that the soil portion of the windproof metal fitting for a stile is bent. The air gap e (Fig. 5) on the back side of the roof tile to be covered with the roof tile makes the upper surface of the roof windbreak fitting for the roof tile elastic and presses down to improve the stable mounting and locking holding force of the roof windbreak bracket. Prevent the roof tiles from rising due to strong wind pressure such as typhoons.

Further, a relief E is provided in a portion adjacent to the step portion 1 and the one-sided side locking portion 4 of the wind-resistant metal fitting for a roof tile, and the height I of the one-sided side locking portion is set to be lower than the thickness of the roof tile. The wind-resistant metal fittings are firmly sandwiched so that the wind-resistant metal fittings for the crosspiece can be stably mounted and the side surface locking and holding force can be improved, and the lateral displacement of the crosstile due to a strong wind pressure such as a typhoon can be prevented.

Next, attaching the windproof metal fittings for a roof tile according to the present invention to the notched corner notches of the roof tile will be described with reference to FIGS. 4 and 5 (Example for Japanese roof tiles). There are usually two corners in the diagonal direction (upper left and lower right for Japanese tiles, upper right and lower left for Western tiles), and square notches (a, b) are provided, which are nailed to the roof. A nailing hole (a) for drilling is provided. Therefore, first, the lower edge of the roof tile A is placed on the upper edge of the roof tile B and nailed, and then the lower right alignment corner notch of the roof tile A (b) and the upper left alignment corner notch of the roof tile C (a). ), The step portion 1 and the one side locking portion 4 of the windproof metal fitting for the crosspiece are sandwiched, and the lower surface locking portion 3 is locked to the lower surface edge of the alignment angle cutout portion (a) of the crosstile C. Then, the ridge C is nailed by being pressed against the upper right edge of the lower ridge B and sandwiched. The upper surface locking portion 2 is locked to the upper edge of the fitting angle cutout portion (b) of the roof tile A, and the roof tile D is laid from above, and the windproof metal fittings for the roof tile are attached at the lower left edge of the roof tile D. To be done. Install windbreak metal fittings for all the roof tiles on all the notches at the corners as described above.

The operation of the windproof metal fittings for the roof tiles installed as described above will be described with reference to FIGS. 4 and 5. The lower surface locking portion 3 of the windproof metal fittings for the roof tiles is connected to the fitting angle cutout portion (a) of the roof tile C. It is locked to the lower surface edge and pressed against the right edge of the upper surface of the lower roof tile B to be sandwiched, and the step portion 1 and the one side locking portion 4 are sandwiched by the mating surfaces of the corner angle notches of the roof tile A and the roof tile C. Since the windproof metal fittings for the sash are firmly held, it is possible to prevent the sash from rising and slipping sideways. In order to firmly sandwich the step portion 1 and the one-sided side locking portion 4 of the wind-proof metal fittings for the roofing tiles at the mating surfaces of the joint angle cut-off portions of the roof tiles A and C, the step portion 1 and one side surface can be improved. It is preferable to provide a relief E (FIGS. 3 to 4) of 3 to 5 mm in the adjacent portion of the locking portion 4, and the height I (FIGS. 1 to 3) of the one-sided locking portion 4 is equal to that of the crosspiece. It is preferable that the thickness is 3 to 5 mm lower than the thickness.

In addition, the windproof metal fitting for a sash of the present invention is an upper surface locking portion 2, which is locked to the upper edge of the lower right corner fitting notch (b) of the stile to prevent the slab from rising due to a strong wind pressure such as a typhoon. Although it is prevented, the lower right corner corner notch (b) of the roof tile is located farthest from the nailing position, so the moment that tries to lift the roof tile is large, and the nailing effect is almost non-existent. . Therefore, it is most effective to lock the notch on the lower right corner of the roof tile so that it does not rise.

Further, the upper surface locking portion 2 of the windproof metal fitting for the roof tiles locks the upper surface edge of the lower right fitting corner notch (b) of the roof tile, but the back surface void portion e of the roof tile covering from above (see FIG. 5). ), Since the upper surface locking portion 2 is in a free state without support, when a strong wind pressure such as a typhoon repeatedly exerts a force to lift the crosstiles upward, the locking portion bent at a right angle. The angle is opened, and the locking and holding force tends to decrease. Therefore, in the case of a thin plate with low rigidity, the windproof metal fittings for the roof tiles may be reinforced by providing ribs on the upper surface engaging portion 2, the step portion 1, and the lower surface engaging portion 3 as shown in FIG. As shown in FIG. 3, the upper surface locking portion 2 is bent so as to be slightly more acute than the right angle, the tip portion is bent in the opposite direction, and the tip portion of the upper surface locking portion 2 is moved upward so as to have elasticity. By making contact with the void portion (FIG. 5) of the roof tile covered with the above, the retaining force of the windproof metal fittings for the roof tile is improved.

[Effect of the invention]

 The windproof metal fittings for a roof tile according to the present invention can be detachably attached to the notch of the corner of the roof tile instead of being attached by using nails, screws, bolts, etc. Therefore, the construction cost will not increase. In addition, since the windproof metal fittings for the roof tiles are mounted without being exposed on the surface of the roof tiles, the appearance is completely the same as the conventional construction without using the metal fittings, and the appearance is not damaged. Furthermore, since it can be manufactured by bending using a thin metal plate, it can be mass-produced with a press die, and can be manufactured at low cost and with a short delivery time. There are advantages such as.
