[Conventional technology]

Generally, roof shingles made of metal sheets were laid horizontally from the eave side to the ridge side, that is, from the bottom to the top.
Lately, it has become common to lay roofing sheets horizontally from the ridge side to the eaves side because it causes less damage to the roofing sheets and can be easily installed on steeply sloped roofs.

The inventor has also developed a roof as described above in which the connecting parts of the ridge side and eave side roof panels are connected and held to the rafters using hangers fixed to the metal rafters. has been proposed.

[Problem that the invention seeks to solve]

The above-mentioned hangers that hold and connect the engaging connection parts of the ridge side and eave side roof plates to the metal rafters are connected to the rafters at two points, the ridge side and the eave side, in order to stabilize the hangers relative to the rafters. preferred for binding, but
This makes it difficult to position and connect the end of the ridge side of the hanger to the rafters, and the work of positioning and locking the engaging connection parts of the ridge and eave side roof plates to the hanger becomes troublesome, and the work becomes difficult. There was a problem that the sex was not good.

The present invention solves the above-mentioned problems, and enables the hanger to be stably and firmly engaged with the metal rafters, and also enables the engagement connection portions of the ridge and eave side roof plates to be reliably engaged with the hanger. Moreover, the object of the present invention is to provide a roof that is covered with shingles from the ridge side to the eaves side, and allows these operations to be performed with good workability.

[Means for solving problems]

The present invention provides a roof in which roof plates made of metal plates are roofed horizontally from the ridge side to the eaves side, and a metal rafter having protrusions for positioning and engaging hangers formed on the top plate, and a ridge on the ridge side end of the mounting plate. The rising board is raised up via the engagement protrusion that curves to the side and protrudes, the locking plate is bent from the upper end of the rising board toward the eaves, and the roof board hooking part is attached to the eave side end of this locking board. The formed hanger and the ridge side,
a roof plate having an engaging portion formed on each eave side, a hanging board mounting plate is supported on the top plate of the rafter, and the engaging protrusion of the hanging hanger is engaged and supported on the eave side of the rafter projection. At the same time, the locking plate of the hanger surrounds and engages the eave-side engaging part of the ridge-side roof board, and this eave-side engaging part is held by the ridge-side engaging part of the eave-side roof board, and this ridge A hook part provided at the end edge of the side engaging part is hooked on the roof board hook part of the hanger, and the eave side end of the hanging plate's mounting plate is fixed to the top plate of the rafter.
