BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure such as a unit building and a joint structure between roof units connecting the roof units.

[0002]

2. Description of the Related Art In a unit building, roof materials are preliminarily applied to a roof panel at a factory or the like on roof panels other than the vicinity of a connection portion where connection roof materials are applied, and the roof units are transported to a construction site. After assembling into the unit building,
It has been practiced to construct a connecting roof material at the connecting portion of the roof unit to connect the roof units to each other to reduce the risk of work at high places and prevent construction delay due to weather.

For example, a metal-molded short roof tile is preliminarily applied to a portion other than the vicinity of the connecting portion between the divided roof portion and the divided roof portion of the unit building, and after the divided roof portion is assembled, it is connected onto the connecting portion of the divided roof portion. For constructing a roof material for constructing a metal-molded short roof tile for roofing, or a method for constructing a roof material for mounting a metal-molded roof tile for connection by nailing it to a pier fixed to a split roof (Japanese Patent Laid-Open No. 5-33427) (See) is known.

Further, the upper end side of the lower roof panel is mounted on the roof panel support member, the lower end side of the upper roof panel is overlaid on the lower roof panel, and the lower end side of the upper roof panel is attached to the roof panel support member. An assembly structure of a roof panel fixed via a tool (see Japanese Utility Model Laid-Open No. 3-55422) is known.

[0005]

By the way, in the above-mentioned method for constructing a roofing material, a roof panel in which a metal-molded short roof tile is previously attached to a portion other than the vicinity of the connection portion is transported to the construction site of the unit building in the factory. After assembling into the unit building,
When applying a metal-molded short roof tile to the connection part of the roof panel, the upper edge of this metal-molded short roof tile is lifted and elastically deformed with the lower edge of the pre-mounted upper side metal-molded short roof tile. Since it is inserted into the lower edge and overlapped with each other, there is a problem that construction cannot be performed unless the roof material is deformable, such as a metal roof tile.

Further, in the above roof panel assembly structure, since the lower end side of the upper roof panel is overlapped and connected to the lower roof panel, a large step is generated between the upper roof panel and the lower roof panel, There was a problem that it was not aesthetically pleasing.

The present invention has been made in view of the above problems, and provides a joint structure between roof units which simplifies the roofing work on site, stabilizes the quality and reduces the cost. The purpose is to

[0008]

A joint structure between roof units according to the present invention is provided between a roof unit for connecting an upper roof unit and a lower roof unit, in which roofing materials are preliminarily applied to roof panels other than the vicinity of a connecting portion. In the joint structure, an insertion portion into which a connecting roof material that connects the upper roof unit and the lower roof unit can be inserted is provided in advance at a lower end portion of the upper roof unit, and the connecting roof material is inserted into the insertion portion to insert the upper roof unit. And the lower roof unit are connected to each other.

In the joint structure between the roof units of the present invention, a means for previously providing an insertion portion into which the connecting roof material can be inserted at the lower end portion of the upper roof unit is to install the roof material at the lower end portion of the upper roof unit. A means for providing a roof material on the spigot in advance and connecting the roof material on it, or a leg is provided on the back side of the roof material at the lower end of the upper roof unit to connect. Means for providing an insertion portion into which the roof material can be inserted, or means for holding an edge portion of the roof material at the lower end of the upper roof unit with a special suspension and providing an insertion portion into which the connection roof material can be inserted, etc. To be

[0010]

In the joint structure between the roof units of the present invention, in the joint structure between the roof units for connecting the upper roof unit and the lower roof unit in which the roof material is preliminarily applied to the roof panels other than the vicinity of the connecting portion, An insertion portion into which a connecting roof material for connecting the upper roof unit and the lower roof unit can be inserted is provided in advance at the lower end portion of the upper roof unit, and the connecting roof material is inserted into this insertion portion to insert the upper roof unit and the lower roof unit. Since, is connected to the lower roof of the upper roof unit at the factory, an insertion portion into which the connecting roof material can be inserted is provided in advance, and at the construction site such as a construction site, the connecting roof material is connected to the lower end of the upper roof unit. The upper roof unit and the lower roof unit are connected simply by inserting them into the insertion section provided on the lower part and fixing the connecting roof material to the lower roof panel with nails or the like. That. This simplifies the roofing work on site and reduces costs.

Further, since the roof unit is manufactured in advance in a factory or the like, the risk of working at a high place is reduced and the construction work is prevented from being delayed due to the weather, so that the quality is stabilized and the cost is reduced.
