Description

Description: TECHNICAL FIELD The present invention relates to a fastening fitting for an end portion of a rectangular hollow outer wall plate provided with a plurality of parallel through holes in a length direction.

[Conventional technology]

In general, hollow molded outer wall panels made by extrusion molding cement mortar, asbestos cement mortar, etc.
For the purpose of reducing cost and improving heat insulation, as shown in FIG. 7, openings are formed in a row in a direction perpendicular to the extrusion molding direction of the outer wall plate 1, that is, the length direction,
A large number of through holes 2 penetrating the hollow molded outer wall plate 1 in the lengthwise direction are provided in parallel. The longitudinal end edges 3, 3 of the hollow molded outer wall plate 1 have a real structure or a phased structure for the purpose of convenience in construction, waterproof function and the like.

When attaching the outer wall plate to a building or the like, the both edge portions 3 and 3 are laterally arranged, and the upper and lower edge portions are engaged with each other to be attached sequentially upward. As shown in FIG. 4, the surface is fixed to the base 5 with nails or screws 4 or the like.

[Problems to be solved by the invention]

However, if the vicinity of the opening of the through hole is fixed with a screw or the like, the outer wall plate is likely to be damaged due to expansion and contraction due to the temperature difference. Therefore, it is necessary to screw it at a considerable distance from the end edge 6 of the opening of the through hole, or to form a long hole so as to be slidable in the longitudinal direction. However, in the former case, the end may be lifted and a step may be added, impairing the appearance,
The latter had the drawback of being troublesome.

In view of the above circumstances, the present invention provides a fastening metal fitting that can easily fasten the edge portion of the outer wall plate where the through hole is open, with a good appearance and without being damaged by expansion or contraction. To aim.

[Means for solving problems]

The present invention has been made to achieve the above object,
The point is that when a hollow molded outer wall plate having a plurality of parallel through holes extending in the length direction is attached to a building base, the through holes of the adjacent outer wall plates are opened and face each other at a predetermined interval. Which is a metal fitting for the edge portion of the hollow molded outer wall plate, the locking plate part whose surface comes into contact with the open end face of the through hole, and the locking plate part which is attached perpendicularly to the surface of the locking plate part. A plurality of locking claws that are respectively inserted into the openings of the through holes, an engagement plate part that is attached to the upper edge of the locking plate part and that is attached in a direction away from the end surface where the through hole opens, and this engagement plate part. The lengthwise center of the plywood part and the vertical distance from the locking plate part are
A long hole which is long in the lengthwise direction and is formed at a position approximately half the predetermined distance, and one end of the engaging plate portion in the lengthwise direction which communicates with the center of the long hole in the widthwise direction. A fastening metal fitting for an end edge portion of a hollow molded outer wall plate having a cut parallel to the surface of the locking plate portion.

[Specific Structure and Action of Invention]

 The present invention will be described below with reference to the drawings.

FIGS. 1 (a) (b) (c) and FIG. 2 show an embodiment of a fastening metal fitting (hereinafter referred to as a metal fitting) of an end portion of a hollow molded outer wall plate according to the present invention. a) (b) (c)
Is a perspective view, and FIG. 2 is a view showing the relationship between the through-hole opening surface of the outer wall plate 1 and the metal fitting.

Reference numeral 11 in the drawing indicates that the surface is in contact with the through hole opening surface of the outer wall plate,
It is a rectangular locking plate portion whose width is not larger than 1/2 of the thickness a of the outer wall plate 1. At a distance from the lower edge 11a of the locking plate portion 11 that is not larger than the wall thickness b between the surface of the outer wall plate 1 and the through hole, the lower edge 11a of the locking plate portion 11 is cut and locked. A plurality of locking claws 12 that are bent at right angles to the surface of the plate portion 11 and horizontally are provided at intervals such that they can be inserted into the through hole openings.

An engaging plate portion 13 is attached to the upper edge 11b of the engaging plate portion 11 so as to be on the opposite side of the engaging claw 12. The engagement plate portion 13 is the upper edge 1 of the locking plate portion 11.
A first horizontal portion 14 which is attached to the locking plate portion 1b at a right angle to the locking plate portion 11 and has a width of about 1/2 of the distance c between the through-hole opening ends 6 and 6 of the outer wall plates facing each other; Narrow vertical part 1 mounted at right angles to the other edge of the part 14 and facing upward
5 and a second horizontal portion 16 which is attached at a right angle to the vertical portion 15 and has a width substantially the same as that of the first horizontal portion 14, and its cross section has a crank shape.

A long hole 17 having a long vertical projection is formed in the center of the first and second horizontal portions 14 and 16 on the vertical portion 15 side in the length direction. A cut 18 is formed by cutting between the elongated hole 17 and the edge of the vertical portion 15.

The metal fitting A shown in FIG. 1 (a) configured as described above is
When rotated 180 ° around the long hole, the metal fitting A ′ shown in FIG. 1 (b) is obtained. Notch 18 of these metal fittings A, A ',
When 18 is combined and opened, the shape becomes as shown in FIG. 1 (c), and the locking claw 12 is inserted into the through hole as shown in FIG. 2 with the metal fitting A shown by a solid line and A ′ shown by a two-dot chain line. Like

In order to fasten the edge 6 where the through hole of the outer wall plate is open using the above metal fitting, as shown in FIG.
The metal fittings A and A'combined with the notches 18 and 18 between the end edges 6 and 6 of the outer wall plates 1 and 1 facing each other with the lower edges 11a and 11a of the locking plate portions 11 and 11 close to each other. Let me insert it. At this time, the screw 4 is inserted into the long holes 17, 17 and the base 5
If the screw is lightly screwed on, it is easy to work, and even if the through holes 2 ... Do not match the locking claws 12, the elongated holes 17 allow the metal fittings to move in the longitudinal direction. The locking claws 12 ... Can be matched with the through hole. Then, when the engaging plate portions 13 and 13 are pressed, they are shown in FIGS.
As shown in the plan view and the cross-sectional view in FIG.
Is inserted into the opening of the through hole, and the metal fittings A and A ′ are opened to be in a stable combined state. Next, when the screw 4 is screwed into the base 5, the outer wall plate edge is pressed against the base by the locking claws 12 and is firmly fixed. Moreover, the outer wall plate 1 is free to move in the longitudinal direction, and the outer wall plate is not damaged by its expansion and contraction. The joint material 19 is filled in the joints of the outer wall plate with the fixed edges.

5 and 6 show another embodiment of the present invention,
In FIG. 1 (a) and FIG. 2 equivalent view, the engaging plate portion 13 has a simple shape. In this case, the edge 6 of the outer wall plate 1 is pressed by the surface of the locking plate portion 11, but this force and the locking claw 12 firmly press the edge of the outer wall plate.

The metal fittings can be manufactured by punching a single metal plate and bending it, and since the same metal fittings A and A'are used, the metal fittings can be manufactured at low cost.

[Effect]

As described above, according to the metal fitting of the present invention, by combining two same metal fittings, it is possible to easily and quickly firmly fasten the outer wall plate end portion, and regulate the movement of the outer wall plate in the longitudinal direction. Since it does not, the end portion is not damaged by the expansion and contraction, no labor is required for mounting, the construction efficiency is greatly increased, and the manufacturing cost is low.
