The purpose of this is to enable panels and the like to be joined easily and firmly.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 a, l) shows wall panel A and stud B in an assembled storeroom.
(These will be discussed later.

) is a perspective view showing a fastening fitting C used for joining.

The details of this fastener C are as follows.

That is, a steel plate-like body is bent into a substantially U-shape in a plan view to form the main body portion 1 consisting of a pair of left and right side wall portions 1a, la and a connecting portion 1b connecting these side wall portions.

Upper and lower flange portions 2 are arranged inwardly from the upper and lower edges of the main body portion 1 in a substantially perpendicular direction, respectively, and are approximately U-shaped in plan view.
, 3 are arranged in series.

In the upper and lower flange parts 2 and 3, notches d and d' are formed at the inner edge of one side in the left-right direction and at a position inward of the approximately U-shaped opening end in plan view. There is.

Further, substantially central portions in the vertical direction of the side wall portions 1a, 1a and the connecting portion 1b are each bent so as to protrude inward, and a groove 4 is formed on the outside thereof.

Then, the side wall portion 1 on the side opposite to the cutouts d and d'
A screw hole 5 formed by burring is provided at the bottom of the groove 4 at point a.

FIGS. 2a, l), and c are plan views illustrating the structure of a joint between a wall panel A made of a steel plate and a stud B made of a steel plate using the fastening fitting C in the order of the joining process, Figure 3 is Figure 2C
It is a sectional view taken along the line III-III in FIG.

As shown in the figure, wall panels A and studs B are provided with plate-shaped edge portions a and b1, which are bent in the same direction. Bent pieces a2 and b2 are formed.

Said bent piece a2. b2 is formed by overlapping the plate-like edge portions al and bl with each other, and forming a double-folded piece a2. With the plate-shaped end portions al and bl side ends of b2 in contact and locked with each other, from between both sides of the fastening fitting C in the left and right direction (i.e., from the inside of the approximately U-shape in plan view) , the notch d,
inserted into d'.

When the bolt 6 screwed into the screw hole 5 is rotated in the tightening direction, the state shown in FIG. 2C passes through the state shown in FIG. , the inner edges of the left and right sides of the upper and lower flange portions 2 and 3 (inner edges on the left side in FIGS. 2a, l, c and FIG. 3) and the tip of the bolt 6 are clamped and fixed.

In this clamped and fixed state, the upper and lower flange portions 2 and 3
As shown in FIG. 3, the pressing forces of the inner edge of the bolt 6 and the tip of the bolt 6 act in opposite directions, that is, inward, and the working positions are different vertically. b is curved.

In this embodiment, the bent piece a2 on the wall panel A side is longer than the bent piece b2 on the stud B side in plan view, and as the bolt 6 is tightened, the tip of the bent piece a2 a3 is pressed against the inner edges of notches d and d' and is gradually bent, and as shown in FIG. 2C, bent piece b2 on the stud B side is formed.
It will be shaped to embrace the tip of the.

In addition, the groove 4 improves the strength of the fastener C, and when the bolt 6 is screwed into the screw hole 5 as shown in FIG. This improves the effectiveness of

The screw hole 5 may be replaced by a simple hole without a threaded portion, and in that case, a nut (not shown) may be welded to the position of the hole and the bolt 6 may be screwed into the nut.

In addition, in the description of the embodiment, the connection between wall panel A and stud B was mainly described, but the above-mentioned fastening connection can also be applied to the connection between various panels such as the connection between wall panels A and roof panels. Tool C can be used.

As explained above, the present invention provides bent pieces a2. b2, and on the other hand, the plate-like body is bent into a substantially U-shape in plan view to form a main body portion consisting of a pair of left and right side wall portions and a connecting portion connecting these side wall portions, and the upper portion of the main body portion is , upper and lower flange portions forming a substantially U-shape in plan view are bent and connected inwardly from both lower end edges in a substantially perpendicular direction, and the upper and lower flange portions are further provided with side portions in the left-right direction. A fastening fitting is formed by forming notches d and d' at the inner edge of and at a position inward of the substantially U-shaped opening end in plan view, and the upper and lower flanges of this fastening fitting are The bent piece a2. b2 to the plate-like edge portion a1.
b□ are overlapped with each other, and both folded pieces a2. b
The cutout portion d is in a state where the end portions of the plate-like edge portions al and bl of the two are abutted and locked with each other.

d', insert a bolt into the screw hole provided in the side wall part on the side opposite to the notches d and d', and insert the bolt tip and the upper and lower parts on the side opposite to the bolt. The plate-shaped end portion is sandwiched and fixed between the inner edge of the flange portion.

Therefore, according to the present invention, the following effects can be obtained by the above structure.

■ A main body is formed by bending a plate-like body into a substantially U-shape when viewed from above, and the upper and lower flanges are bent and connected from the upper and lower edges of the main body, respectively, to form a fastening fitting. Therefore, this fastening metal fitting has greater strength and is less likely to deform than one made by simply bending a plate-shaped body.

Therefore, a strong bond can be achieved. ■ Furthermore, when the pair of plate-shaped end edges, each of which is bent and connected from a steel plate panel, etc., are overlapped with each other, the upper and lower flange portions of the fastener are placed between the inner edges of both sides in the left-right direction (approximately U-shaped). (inside the shape), on the tip of the bolt and on the side opposite the bolt,
The plate-like edge is clamped between the inner edges of the lower flange, and in this sandwiched state, the plate-shaped edge Since the upper and lower flange parts are curved, the panels can be firmly connected without shifting or creaking even when subjected to impact from cross winds, etc. Also, since no shifting or creaking occurs, it is possible to firmly connect the panels, etc. The paint applied to the panel etc. will not peel off due to friction etc., and therefore,
It has the effect that there is no risk of rusting.

■Furthermore, bent pieces bent in the same direction are formed at the tips of the pair of overlapping plate-shaped edge parts, and both bent pieces are bent at the ends of the plate-shaped edge parts. Since the bolts are inserted into the notches provided in the upper and lower flanges with the bolts abutting and locking each other, even before the bolts have been tightened, both panels or panels to be joined can be easily connected. Relative movement beyond a certain level of the stud in the direction perpendicular to the panel surface, and relative movement beyond a certain level between both panels or between the stud and panel and the fastener in the direction perpendicular to the panel surface will be prevented. .

Therefore, for example, when joining wall panels to each other or between wall panels and studs, it is possible to prevent the wall panels from falling down, and when joining roof panels to each other, it is possible to prevent the fastening fittings from coming off and falling, improving work efficiency. be.

In addition, even if the fastener is misaligned due to loosening of the bolt, etc., the bent piece will engage the notch and the fastener will be prevented from coming out and falling. There is no risk of accidental separation.

■ In addition, since bent pieces bent in the same direction are formed at the tips of a pair of overlapping plate-shaped edges, deformation of the plate-shaped edges causes Even if there is some gap between the parts, sunlight (or the indoor side) can be prevented from leaking through the gap, and wind and rain can be prevented from blowing directly into the gap.
