[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure having a sloped roof panel member.

[0002]

2. Description of the Related Art As a conventional roof structure of this type, for example, a structure of a unit building having a sloped roof as shown in FIGS. 11 and 12 is known (Japanese Patent Laid-Open No. 8-1080).
Reference).

[0003] In such a building 1, a lower floor living room portion 3 is formed by a plurality of living room units 2 having a substantially box shape. A plurality of roof units 5... 6 constituting the roof unit 4 are mounted on the upper part of the living room unit 3.

The roof unit 5 extends along the ridge substantially at the center of the building 1, and the upper part 5a is formed so as to have a mountain shape projecting upward from the substantially central ridge.

As shown in FIG. 12, the roof unit 6 is mounted on the eaves side of the building 1 with the bottom plate 7 constituting the floor of the roof 3 attached to the lower surface side. It is configured as follows. The upper part 6a of the roof unit 6 is fitted to the top plate 6
By making b and 6b have a substantially triangular shape, the roof panel members 8 are arranged so as to be obliquely cut out and inclined.

Next, the operation of the conventional roof structure will be described.

In the conventional roof structure thus constructed, the roof units 5 are placed along the upper central ridge of the living room 3 and the roof units 6 are mounted.
Are placed side by side along the eaves.

Next, a plurality of flat roof panel members are mounted on the roof units 5 and 6 along the slope to form a gable roof portion 4.

Another conventional roof structure is shown in FIG.
Japanese Patent Application Laid-Open No. H10-110499, which is shown in FIG.

First, the structure will be described. In this roof structure, the living room unit 9 has a wall panel 1 as a bearing wall.
Along with the girder side wall panel 11 arranged orthogonally, 0 is formed in a substantially box shape which is erected on a lower floor panel (not shown) and whose upper part is opened.

A flat panel-shaped structural panel 12 is mounted on the upper part of the living room unit 9 substantially horizontally.
2 constitutes the floor. In this structural panel 12, a plurality of joists 13 are juxtaposed at predetermined intervals.

At the end 13a of the joist 13, an end joist 14 extending along the eaves extending direction (the front-rear direction in the drawing) is machined into a comb-like shape, and is arranged to be orthogonal. . A gypsum board 15 is fixed to the lower surfaces of these joists 13 and end joists 14, and a structural plywood 16 is fixed to the upper surfaces.

A horizontal structural member 18 is disposed between the ends 13a, 13a without any gap.
And it is fixed to the end joist 14 using a nail 20 or the like. Notches 13b, 13b are formed on the upper surfaces of the ends 13a, 13a.
b are formed, and the roof panel member 17 having a predetermined slope is placed in contact with the roof panel member 17.

Further, the roof panel member 17 is fixed to the end portion 13a or the horizontal structural member 18 by a screw nail 21.

These horizontal plane structural members 18 are
The said wall panel 10 is fixed to the upper frame 10a by the bolts 19 with washers.

Further, an outer upper portion of the end wall panel 10;
A roof receiving member 22 is disposed between the roof panel member 17 and the rear surface side.

However, in one conventional roof structure as shown in FIG. 11 or FIG. 12, the height of the roof panel member 8 is equivalent to the thickness a of the bottom plate 7 and the height of the living room. It is set at a position that is raised above the upper end surface 2a of the unit 2. For this reason, there has been a problem that the height of the roof portion 4 is increased and the degree of freedom in design is reduced, for example, the roof portion 4 easily violates the oblique line restriction.

On the other hand, in another conventional roof structure shown in FIG. 13, the load of the roof panel member 17 disposed relatively below by the notch 13b is increased by the horizontal plane structure 18 and the roof. It is transmitted to the upper frame 10a of the end wall panel member 8 via the receiving member 22.

However, since the joists 13 are not directly fixed to the upper frame 10a of the rear wall unit,
There was a problem that the supporting strength was insufficient depending on the size of the house.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roof structure capable of always securing a desired supporting strength and allowing a roof mounting position to be arranged close to an upper end surface of a wall panel of a lower floor room.

The horizontal plate-shaped metal piece is integrally connected to the vertical surface of the edge of the metal beam member by the vertical reinforcing stiffener.

For this reason, a desired supporting strength can always be ensured regardless of the size of the house.

Further, since the horizontal plate-shaped mounting metal piece projects sideways from an edge of a metal beam member juxtaposed substantially horizontally along the bottom surface of the roof portion, The increase in the space occupied by the metal beam member above the column member is suppressed, and the mounting position of the roof panel member of the roof portion is set to a relatively low position close to the upper end surface of the wall panel of the lower floor living room unit. I can do it.

For this reason, for example, it is difficult to violate the oblique line restriction or the like, and the design flexibility can be increased.

According to a second aspect of the present invention, the roof structure according to the first aspect is characterized in that the vertical reinforcing stiffener has an oblique notch on an upper surface side.

According to the second aspect of the present invention, since the vertical reinforcing stiffener has an oblique cutout on the upper surface side, the mounting position of the roof panel member on the roof portion can be changed. It can be a relatively low position close to the upper end surface of the wall panel of the lower floor living room unit.

According to the third aspect of the present invention, the bottom surface is a floor portion of an attic, and an attic unit having an attic in the roof is disposed above a living room unit constituting the living room. Item 1 or 2 is characterized by the roof structure.

According to the third aspect of the present invention, the attic unit in which the metal beam members are juxtaposed on the floor can be formed by placing the attic unit above the living room unit. .

Therefore, the workability is good.

[0033] Further, according to the present invention, at least one pair of the metal beam members is provided at a predetermined interval, and an opening is formed between the metal beam members. The roof structure according to any one of 1 to 3 is characterized.

According to the fourth aspect of the present invention, since the opening is formed between the metal beam members provided at the predetermined interval, the structural strength of the bottom surface of the roof is reduced. It is possible to form a communication passage or the like with a living room space or the like formed in the lower-floor living room unit with almost no deterioration.

Accordingly, it is possible to provide a roof structure which has good workability, satisfies conditions such as oblique line restriction, and has an attic.
