Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal thatched roof having a large step at least in the eaves direction.

[0002]

2. Description of the Related Art A conventional thatched roof as described above will be described with reference to FIG.

In FIG. 7, (1) is a purlin made of C-shaped steel, and a wooden rafter (2) is placed on the purlin (1).
Is erected, and on the rafters (2), large and small Yokogi (3),
(4) are alternately erected in the eaves direction, and a base material (5) is laid on each of a pair of large and small horizontal trees (3), (4) adjacent to the eaves direction, and they are adjacent in the eaves direction. A large step is formed between the base materials (5) to be used.

Further, of the adjacent face plates (6) that are horizontally laid on the base material (5), the ridge-side edge (6a) of the eave-side face plate (6) is raised, and the adjacent ridge side Face plate (6)
The eaves side edge (6b) of the eaves is the ridge side edge (6) of the eaves side face plate (6).
It is bent downward so as to come into contact with a), and is further bent from the lower edge of the bent portion along the rear surface of the base material (5) on the eaves side.

On the other hand, a roofing roof having a large step is also known as shown in Japanese Patent Publication No. 58-16417. In this known invention, the heat insulating plate and the roof plate (building plate) are supported by a horizontal beam member such as a purlin having a U-shaped cross section and a furring strip,
In particular, when engaging the engaging portion of the roof plate in the eaves ridge direction, a simple structure is adopted in which a hanging piece is not used and only the protrusion provided in the cross beam member is engaged.

[0006]

A conventional thatched roof having a large step, which is constructed as shown in FIG. 7, has a droop provided at an eaves side edge portion (6b) of a ridge side face plate (6). Since the part is long, it is easily deformed by an external force, which causes a problem of impairing the appearance.

Further, at the engaging point, the erecting ridge side end portion (6a) of the adjacent eaves side face plate (6) is located below the eaves side end portion (6b) of the adjacent eaves side face plate (6). Since it is only in contact with the eaves side surface of the bent portion that bends, there is also a problem that rainwater easily leaks into the building from a portion with a large step and rain leakage easily occurs.

On the other hand, in Japanese Patent Publication No. 58-16417, as described above, the engaging portion of the roof plate is locked only by the ridge projecting in the cross beam member without using the suspension. Because of the simple configuration, when the action of trying to move the roof plate to the eaves side by the snow load, the load of the worker during construction, etc.,
Since only the protrusions are locked, there is a risk that the entire roof surface will fall off under the eaves, which is not suitable for implementation.

The present invention solves each of the problems described above,
Even if the hanging part provided on the eave side edge of the face plate on the ridge side is lengthened to provide a large step, the hanging part is configured so that it does not easily deform, and the appearance of the roof with a large step is not damaged. In addition, it is possible to prevent rain from leaking by fully considering the rain warding structure at the engaging part of the face plate, improve the design, and provide a side thatched roof that can be constructed only by the roof operator. Has an aim.

[0010]

According to the present invention, in a thatched roof having a large step in at least a part in the eaves direction, a metal rafter (10) is provided on a supporting member such as a concrete frame (9) or a purlin. And has a bottom plate (11a) and a side plate (11b) with an upward spread that rises from the eave side edge of this bottom plate (11a).
A supporting piece (11) for supporting the eaves side end of the base material (13) arranged directly below the face plate (14) of the horizontal thatched roof plate in the upper part of (b).
f) and a stepping member (11) provided with a standing portion (11e) that supports the back surface of the hanging portion (14c) of the face plate (14).
To fix the bottom plate (11a) to the rafter (10), and the ridge-side end of the base material (13) to the rafter (10).
It is supported above and the face plate (14) is laterally laid on the base material (13) to form a large step between the face plates adjacent to each other in the eaves ridge direction, and the ridge side edge of the face plate (14) on the eaves side. The engaging portion (14b) provided on the section and the engaging portion (14d) provided on the eave side edge of the ridge-side face plate (14) via the hanging portion (14c) are engaged with each other, and the rafter ( Hanger (16) fixed to 10)
Is engaged with and held by.

[0011]

[Operation] In the horizontal thatched roof according to the present invention, even if the hanging part provided on the eaves side edge of the face plate on the ridge side becomes long in order to provide a large step, the back surface of the hanging part should be close to the back surface. Since it is supported by the stepped member that also serves as the reinforcing plate, it becomes difficult for the hanging part to deform when receiving an external force,
Therefore, it is possible to prevent the appearance of the roof from being impaired.

Further, since the supporting piece (11f) of the stepping member (11) accurately supports the eaves side end of the base material (13), there is little possibility of deformation even if external pressure is applied to the roof surface. .

Further, the hanging part is deformed due to the engagement between the engaging part provided on the eaves side edge part of the ridge side face plate via the hanging part and the engaging part provided on the ridge side edge part of the eaves side face plate. Therefore, it is possible to prevent rain leakage from the engaging portions of the both engaging portions.

The roof design can be improved by arbitrarily selecting the positions and numbers of the parts having large steps in the above-described structure and appropriately interposing the parts between the parts having ordinary small steps. .

Moreover, since it is sufficient to assemble the rafters, the step members, the base material, and the face plate, it is possible to perform the construction only by the operator having a roof different from the operator constructing the building frame, which is convenient for the workability. , Short-term finishing is possible.
