Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a connection structure for a roof unit. In particular, the present invention relates to a roof unit connection structure suitable for a building having three stories or more.

[0002]

2. Description of the Related Art As described in Japanese Patent Publication No. 5-31616, a first roof unit and a second roof unit are installed side by side as a connection structure of a roof unit.
The upper surface of the structural material such as the rafter of the first roof unit and the upper surface of the structural material such as the rafter of the second roof unit are connected by a sheet metal connector, and the structural materials are connected by nailing from the side. It is known.

However, when the roof units are joined by the connection structure, in a three-story building or more, when the wind blows strongly, the first roof unit and the second roof unit are not connected. May bend or separate. That is, although it depends on the angle of inclination of the roof, with a normal inclination, when the wind blows strongly, a force acts to lift the roof on the leeward side. Generally, the wind blows stronger in a tall building such as a three-story roof blowing more strongly than a two-story roof. Therefore, in a tall building such as a three-story building, a normal one-story building or a two-story building is used. It is necessary to make the installation strength of the roof unit stronger than that of the building.

[0004] Then, as described above,
If the roof units are connected to each other with a sheet metal connector attached to the top of the rafter, the sheet metal connector connecting the tops of the rafters lifts the roof unit upwards and forms an inverted letter. Low resistance to bending forces,
Therefore, the joint of the roof unit may be bent or separated. Incidentally, in the conventionally known joining structure of roof units, at the same time as connecting with a joining tool, a nail is driven from one rafter to the other rafter to prevent this separation or bending, but as described above, When the force for lifting the roof upward is repeatedly repeated, the fastening force of the nail gradually loosens, and eventually the nail is easily pulled out and the effect may be lost.

Accordingly, an object of the present invention is to provide a roof unit mounting structure in which a roof unit does not bend or separate at a joint even when a strong wind blows.

[0006]
