Description

[Detailed description of the invention] [Industrial field of application] The present invention is useful for connecting two members of a building to each other, for example, when connecting a roof edge member for attaching a ceiling board to a roof edge receiving member. This relates to a connecting fitting for connecting.

[Conventional technology]

As shown in FIG.
Suspend the field edge receiving member 22 made of shaped steel via b,
A field edge member 2 having a rectangular cross section has grooves 23a extending in the longitudinal direction formed on both left and right side surfaces of the field edge receiving member 22.
3 is fixed so that the field edge member 23 is substantially perpendicular to the field edge receiving member 22, and a ceiling plate 24 is stretched on the lower surface of this field edge member 23. In order to facilitate the work of attaching the field edge member 23 to the frame member 22, a connecting fitting 25 as shown in FIG. 9 is used.

That is, this conventional connecting fitting 25 includes a fitting main body 25a formed with a downward U-shaped cross section so as to fit onto the field edge member 23, and a pair of left and right protrusions cut upward on the upper surface plate of the fitting main body 25a. Piece 25
b, and a field edge receiving member 2 is attached to the projecting piece 25b.
An engaging groove 26 into which the flange 22a of the metal fitting body 25a fits is cut out, and locking pieces 27 that engage with the grooves 23a on both left and right side surfaces of the field edge member 23 are formed inside the left and right side plates of the metal fitting body 25a. It was formed by cutting it in the opposite direction.

[Problem that the invention attempts to solve]

With this configuration, by fitting the engagement groove 26 into the flange 22a of the field edge receiving member 22 and hammering it in from the side, the connecting fitting 2
5 can be fixed to the field edge receiving member 22 so as not to fall off, and the field edge member 23 can be attached to the connecting metal fitting 25 with one touch by simply pushing it from below between the left and right side plates of the connecting metal fitting 25. Although there is an advantage in that the field edge member 23 and the field edge receiving member 22 can be connected extremely easily, as described below, the connecting fitting 25 is easily deformed and damaged, and the connecting fitting 25 and the field edge receiving member 22 are easily connected. The problem was that the strength of the connection was also low.

That is, the protruding piece 25b having the engagement groove 26
is formed by cutting and raising the top plate of the metal fitting main body 25a, and its thickness is thin, and the width of the connecting part with the metal fitting main body 25a is also small, so that the engagement groove 26 of the protruding piece 25b has a small thickness. If the plate thickness of the flange 22a to which it is fitted is a little thick or loose, the protruding piece 25b will bend sideways or be damaged when it is hammered into the flange 22a.

Moreover, when both protrusions 25a are formed by cutting and raising, the length from front to back is naturally shorter than the length from front to back of the metal fitting main body 25a, so the engagement groove 2
7 becomes shallower and the length of engagement with the flange 22a becomes smaller, and the distance between the protrusions 25a also becomes narrower than the left and right width of the fitting body 25a. The attachment strength of No. 25 to the field edge receiving member 22 was low in both left, right, front and rear directions.

The object of the present invention is to provide a connecting fitting that solves this problem.

[Means for solving problems]

In order to achieve this objective, the present invention integrally forms U-shaped tabs on both left and right ends of the top plate made of a metal plate, each of which is bent upward and then folded downward. The outer pieces of both ear pieces are each extended downward to form a side plate, and each side plate is provided with a locking claw that engages with one of the two members that are connected to each other. In addition, an engaging groove is provided in each of the two members to which the flange of the other member of the two members connected to each other is fitted.

[Functions and effects of the idea]

In this way, U-shaped ears that are bent upward and then folded downward are integrally formed on both the left and right ends of the top plate of the connecting fitting.
If both of the ear pieces are provided with engagement grooves into which the flanges of the other member are fitted, the ear pieces with the engagement grooves are stacked in two layers, and their strength is lower than that of the above-mentioned conventional protrusion with the engagement grooves 26. Since it is much higher than the piece 25b, it is possible to reliably prevent bending, deformation, or damage when the other member is hammered into the flange.

Moreover, the length of both of the ear pieces is the same as the front and back length of the top plate, and the length of the engagement groove can be made much longer than in the conventional case described above.
The distance between the two ear pieces is the same as the left and right width of the top plate, and is wider than the conventional case described above. can also be significantly improved.

Therefore, according to the present invention, when connecting members to each other, it is possible to reliably and firmly connect the members to each other without bending or deforming the connecting fittings or causing damage.
