Description

[Detailed explanation of the invention] The present invention relates to a fastener for fixing a rafter to a material, and the width and thickness of the rafter or the mounting angle can be freely fixed according to the angle. This invention relates to a fastener for rafters.

As shown in Fig. 1, the commonly used fasteners for rafters are made by bending a metal strip into the shape of a front gate.The left and right hanging pieces (a) and the middle part (b) of the main body of the metal fitting (a) are twisted by 90°C, respectively, as shown in Fig. 1. C, the rafter d is interposed within the main body a of the gate-shaped metal fitting, and each hanging piece s and b below the screw c and c are sealed by contacting the front side of the material. This is the current situation.

However, with such metal fittings, the shape of the metal main body a is constant, so if the width of the rafter d does not fit within the gate shape or the thickness is thicker than the twisted part c of each hanging piece b, There was a disadvantage that it was impossible to straddle the rafters d, and therefore there was a great disadvantage that fittings were required to suit each size of each rafter d.

The present invention eliminates these conventional disadvantages and provides a fastener having the following structure which is simple and advantageous.

That is, as shown in the drawing, a metal band is bent along the plate surface into a generally upside-down L-shape, and the three long and short pieces of the metal fitting main body 1 are cut out from the three long and short pieces M and M'. Each strip-shaped installation whose plate surface is perpendicular to the plane of the plate surface of these base pieces is piece 2,
In the drawing, 3 is a nail hole, 4 is a nail, 5 is a rafter, and 6 is a support for a mist.

Since the present invention is constructed as described above, when fixing the rafter 5 to the support material 6 using the present fastener, first place the long piece M of the metal fitting body 1 on the top surface of the rafter 5, and then tighten the corner part. Nail holes 3 in the long piece M located on the upper surface of the rafter 5 are aligned with one side corner of the rafter 5 (see dashed lines in Figure 3), and then the long piece is bent vertically downward from the opposite corner of the rafter 5. (Refer to the solid line in Figure 3 to secure the metal fittings to the rafters 5 by driving nails 4.) Next, depending on the hanging state of the rafters and supports with the timbers 6, each band-shaped attachment is done with pieces 2 and 2'. The receiver is attached to the front surface of the material 6, and the receiver is bent vertically downward from the corner of the material, so that each mounting piece 2, 2' is brought into contact with the front surface of the material 6. The attachment is completed by driving a nail 4 through each nail hole 3.

(See Figure 4) As mentioned above, the main body of the metal fitting consists of three long and short pieces bent in an upside-down L-shape from the front, so when fixing a rafter, first place the long pieces on the top of the rafter. After aligning the corners, bend the open end of the long piece vertically downward to fit the width of the rafter and straddle it. Since it is bent, it can be hung without any restrictions on the thickness of the rafters, and therefore it can always be freely fitted to rafters of various sizes, and the bridge has the effect of being hung on the timber. This is an advantageous device that can be easily lowered as a rafter stopper.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a conventional rafter fastener, illustrating the state in which it straddles a rafter. Fig. 2 is a slope view of the proposed rafter fastening fitting, and Fig. 3 is a front view showing the proposed fitting astride the rafters, and each mounting piece is fixed to the front side of the material, and the chain line indicates the long piece. Fig. 4 is a perspective view illustrating the installation process in which the bracket is placed on the upper surface of the rafter, and the rafter is diagonally suspended on the support member and fixed via the metal fitting of the present invention. 1 is the metal fitting main body, M is the long piece M/ is the short piece, and 2.2' is the mounting piece.

Claims (1)

[Scope of utility model registration request] At each end of the three long and short pieces of the metal fitting main body 1, which consists of long and short pieces M and M' made by bending a strip of gold along its plate surface into a substantially upside-down L-shape from the front, attach the plate surface to the plate of these base pieces. Each band-shaped installation, which is perpendicular to the surface and the outside, is a rafter fastener with pieces 2 and 2' connected in series.
