Description

Description: TECHNICAL FIELD The present invention relates to a dorma having a steel frame on the front surface, which is excellent in strength and large in size and which can be used as a living room.

[Conventional technology]

Traditionally, ventilation in the attic, lighting in the room below the sloping roof,
In addition to ventilation and the like, a dormer is sometimes used for the sloping roof in order to add an accent to the sloping roof and enhance the appearance of the house.

Therefore, in the past, such a dormer was relatively small,
Greater strength is also not required and the skeleton forming the dormer is formed using a wooden frame.

On the other hand, in recent years, it has been desired to utilize a house space, especially an attic.

[Problems to be Solved by the Invention]

However, even in a house having a sloping roof with both flows, when the space under the sloping roof is small, the shack is conventionally left unattended or used only as a storage place for articles. It has not been.

Therefore, as a result of various studies on the effective use of the attic space in such a case, the present inventor has focused on the dorma that has been conventionally used for the attic ventilation, the lighting of the living room below, and the like. Notice that it can be used as a living room by forming a relatively large space under the sloping roof by using a steel frame instead of the wooden frame used in front of the conventional dormer. By doing so, we have completed a dome that has excellent strength and can be made larger.

It is an object of the present invention to provide a dormer having a steel frame on the front surface, which has excellent strength and which can be relatively easily increased in size.

[Means for solving the problem]

The present invention is a dormer that is arranged on a sloping roof with the front surface facing downward of the flow of the sloping roof, and is a pair of steel strut members and a steel slant member that extends obliquely upward from the upper ends of each strut member And the upper end of the diagonal member is joined to form a chevron, and the lower end of the strut member is horizontal and has a length longer than the distance between the strut members and protruding from the strut member and is made of steel. A frame body bolted to the lower rootstock that is fixed to the top,
Also, the dormer is characterized in that the front base is provided with a wooden side frame body having a wooden diagonal member which is provided in a protruding portion where the lower rootstock extends from each of the supporting columns and is aligned with the diagonal member.

[Action]

The dormer includes a steel frame body composed of a pair of strut members and diagonal members arranged diagonally and in a mountain shape at the upper ends of the strut members.
As a result, the rigidity and strength of the dome frame is increased as compared with a conventional dome using a wooden frame, and the frame is fixed to the steel purlin at the lower end of the strut member via the lower stock,
Furthermore, the strength and rigidity of the dome frame can be increased, and the dome frame can be made large enough to form a living room or the like in the attic.
