Description

[Detailed description of the invention] The present invention is intended to be used as a unit-type eave that is attached to an external wall panel L above windows, doorways, etc. in a prefabricated house, and is particularly intended to simplify wall surface treatment and facilitate installation. At the same time, the purpose is to perfect the drainage process and provide a small eave that is highly durable and robust.

In prefabricated houses, relatively narrow eaves are installed above windows and other openings on the exterior walls of the house to block wind, rain and sunlight, or as a blindfold, and are usually referred to as indomitable eaves. Because they are installed on the exterior wall panels of prefabricated houses, most of them are of the unit type, and have a structure and design that allows for easy post-installation after the exterior wall panels have been stretched.

The most important thing in this case is drainage treatment, especially at the attachment part of one end of the eaves on the outer wall panel surface, as the eaves are exposed to wind and rain.

A structure in which one end of the eaves is embedded before constructing the wall surface can effectively and reliably drain the water, but a prefabricated type in which one end of the eaves is attached to the outer wall panel surface requires that the outer wall surface be drained when draining. It is difficult to make incisions, and it is technically difficult to make a complete watertight seal without requiring significant modifications or additional structures to the extended wall side during construction. Eye coating etc. has problems such as poor durability.

The present invention solves these problems, and its feature is that the inner end of the roof plate of the unyielding body that protrudes outward from the outer wall panel of the prefabricated house is drained by a flat bottom drainer. In the flat bottom for prefabricated houses, the flat bottom drain has a U-shaped cross section with an inward bent edge at the -L portion and a lower bent edge, and the upper bent edge and The lower bent edge is tightened and fixed to the outer wall panel so that it is along the outer wall panel, and the outer wall panel and 1-゛1
A sealing material is sandwiched between the outer wall panel and the lower bent edge, and a bent retaining edge that bends the inner edge of the roof sheet upwards is attached to the upper edge. The upper end of the bent locking edge is bent upwardly from the vicinity of the lower bent edge, and the upper end of the bending locking edge is bent outwardly upward from the vicinity of the lower bent edge, and the upper end of the bending locking edge is bent outwardly upward from the vicinity of the lower bending edge, and between the upper end and the outer wall panel.
