Description

  The present invention relates to a cage structure of a building such as a house.

When building a building such as a house, it is known that the lower end of the roof in the inclined direction protrudes from the outer wall to form the eaves.
However, if the eaves are large, the window on the outer wall may be covered, and the sun may be blocked more than necessary. Buildings that have been developed have been developed (see, for example, Patent Document 1).
JP 2008-002227 A

However, when the eaves are too small as in Patent Document 1, for example, if a window is opened on a rainy day, a lot of rainwater tends to be driven directly into the building from the window, and the window is close to the ground on the first floor. There is a problem that a lot of rainwater and mud that bounces off the ground can easily enter the building from the window. Therefore, there is a demand to provide a ridge that protrudes to the outside rather than the outer wall of the building above the opening such as a window.
However, if the ridges are arranged along the inclination direction of the roof, they are covered with windows, so that the sun may be blocked more than necessary as in the conventional case. In addition, in order to prevent rainwater and mud from entering in the past, there is a desire to increase the protruding length of this kite from the outer wall. However, simply fixing this kite to the outer wall can withstand the weight of snow. There is a problem that can not be.

  An object of the present invention is to provide a ridge structure that can increase the protruding length without blocking the sun more than necessary.
