JPS5930088Y2 - Connection fittings for rafters to horizontal structural members - Google Patents

Description

[Detailed description of the invention] The present invention relates to a fitting for connecting a rafter to a horizontal structural member such as a metal purlin. The upper horizontal piece 4 of 3 is provided with a notch 5 that can be inserted and connected from the side edge of the eaves side, and the vertical plate 2 is provided with a nail hole 6 for the rafter 1, and a receiving plate that can abut against the lower surface of the rafter 1. This is related to a fitting for connecting rafters to horizontal structural members provided with 7, and its purpose is to connect vertical boards to horizontal structural members such as metal purlins with I-shaped cross-section. By providing a notch in the upper horizontal piece of the approximately ■-shaped horizontal structure material that can be inserted and connected from the eaves side, and by providing a receiving plate in the vertical board that can come into contact with the bottom surface of the rafter, most of the weight of the rafter can be reduced. This makes it possible to avoid concentrating the stress caused by the weight of the water on the nails driven horizontally into the rafters. The purpose of the present invention is to provide a fitting for connecting rafters to horizontal structural members that can be stably connected and supported over a long period of time.

Embodiments of the present invention will be described in detail below with reference to the drawings.

A is a connecting fitting, such as an iron plate that can come into contact with the lower surface of the rafter 1 that is constructed with a roof slope on the vertical plate 2 of a metal plate such as an iron plate that can come into contact with the side surface of the rafter 1. The metal receiving plate 7 is welded.

A plurality of nail holes 6 are formed in the upper half of the vertical board 2.

A notch 5 is formed in the lower half of the vertical board 2 so that it can be inserted into and connected to the upper horizontal piece 4 of the metal purlin 3, which is a horizontal structure member, from the eaves side.

This notch 5 is tapered to become slightly narrower toward the back to form the above-mentioned connection fitting A.

Numeral 8 is a clamping piece having the same shape and size as the vertical plate 2, and is provided with a nail hole 6 and a notch 5.

The metal purlin 3 is made of a beam material having an I-shaped cross section, in which the bottom pieces of channel materials are brought into contact with each other and connected.

However, as shown in Fig. 3, the notch 5 of the vertical board 2 is inserted into the edge of the upper horizontal piece 40 of the metal purlin 3, and connected by hammering, etc., and then attached to the vertical board 2. The rafters 1 are constructed by attaching the lower surface of the rafters 1 to the upper surface of the receiving plate 7, which is welded with a slope approximately equal to the roof slope. ) to attach the rafters 1 to the metal purlin 3.

When the rafter 1 breaks, most of its weight is supported by the receiving plate 7, and stress is concentrated on the driven nails, preventing them from breaking.

As shown in FIG. 3, on the other side of the rafter 1, a clamping piece 8 has a notch 5 driven into the metal purlin 3, and a nail is driven into the rafter 1 through the nail hole 6. As a result, the rafter 1 is held between the connecting fitting A and the holding piece 8.

As mentioned above, in the present invention, when attaching rafters to a horizontal structural member having an I-shaped cross section, it is possible to connect the rafters by inserting them into the upper horizontal piece of the approximately ■-shaped horizontal structural member from the eave side of the vertical board. Since the vertical board is equipped with a receiving plate that can come into contact with the bottom surface of the rafter, most of the weight of the rafter can be received by the receiving plate, and this allows the wood to be hit horizontally. This method has the advantage that it is possible to avoid concentrating stress caused by the weight of water on the inserted nails, and therefore the rafters can be stably connected and supported to the horizontal structural members over a long period of time.
