Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel which constitutes a base of a roof, and more particularly to a roof panel which enables a roof frame to have a simple structure.

[0002]

2. Description of the Related Art Steel-framed buildings are widely used in residential construction and the like. As shown schematically in FIG. 5, the roof frame structure in such a building is composed of a plurality of bundles 51, which are used as the main beams 52,
Supporting the main house 53 and eaves beams 54, arranging climbing beams 55 at both ends of the roof with a preset slope, and arranging rafters 56 parallel to the climbing beams 55 on the master beam 52 and eaves beams 54. There is. Further, a base plate 57 is attached over the entire surface of the rafter 56, and a waterproof sheet 58 is attached to the base plate 57 to form a base of the roof.

Since the beams and the purlins are arranged in parallel or at right angles, the surface structure 59 formed by these members is rectangular. Therefore, by arranging the brace 60 on the diagonal line of the surface structure 59, the rigidity of the roof frame is increased.

[0004]

SUMMARY OF THE INVENTION In the above conventional steel-frame-structured building, when the roof is constructed, the skeleton work for assembling the skeleton and the carpentry work for attaching the ground plate are sequentially carried out. Need different workers. For this reason, strict process control is required, and there are many types of jobs, so there is a problem that the construction time becomes long.

Further, since many rafters and braces are required due to the structure, the number and kinds of members are inevitably increased, which complicates inventory management and lengthens the construction time.

An object of the present invention is to provide a roof panel which can reduce the number of types of work required for construction work in constructing a roof of a building, the number and types of members, and the construction time. To do.

[0007]

In order to solve the above problems, the roof panel according to the present invention is constructed by attaching a surface material to a frame-shaped frame having a preset strength.

[0008]

Since the roof panel is constructed by attaching the surface material to the frame having a preset strength, the surface material can be made to function as a ground plate. Therefore, the roof panel can be completed at the same time by attaching the roof panel to the roof frame. Since the above-mentioned work is performed by the hawk, carpentry work can be omitted when constructing the roof.

Further, the frame of the roof panel can be made to function as a rafter, and high rigidity can be imparted in a direction parallel to the panel surface by integrally mounting the surface material on the frame. For this reason,
It is possible to omit rafters and braces from the roof structure,
The number and types of members can be reduced.

EXAMPLES Examples of the roof panel will be described below with reference to the drawings. 1 is a perspective view illustrating the structure of a roof panel, FIG. 2 is a view illustrating the structure of a frame, FIG. 3 is a view illustrating the relationship between a roof frame and a roof panel, and FIG. 4 is an example of a bracket that connects the roof panels. It is a figure explaining.

The roof panel A has a sufficient strength against an external force acting in a direction perpendicular to the panel surface and a sufficiently high rigidity against an external force acting in a direction parallel to the panel surface. It is configured so that it can function as a structural member that constitutes a part of the roof skeleton. When the roof panel A is attached to the roof skeleton, a part of the base of the roof can be completed at the same time.

As shown in FIGS. 1 and 2, the roof panel A
Is composed of a frame 1 formed in a frame shape and a surface material 2 attached to one surface of the frame 1.
Then, when the frame 1 and the surface material 2 are integrated, a preset rigidity can be exerted.

The frame 1 includes two horizontal members 1a arranged in the width direction and forming end portions in the vertical direction, two vertical members 1b arranged in the vertical direction and forming end portions in the width direction, and a vertical portion. And a plurality of reinforcing members 1c arranged in the direction. Each of these members 1a to 1c is made of a channel-shaped steel material, and has dimensions sufficient to satisfy the design load set at the time of designing the building.

The frame 1 is formed in a rectangular frame shape by arranging the above-mentioned members 1a to 1c at predetermined positions and fixing the joints with other members by means such as welding. The widthwise and longitudinal dimensions of the frame 1 are
It is set according to a preset module size.

Therefore, a plurality of types of frame 1 (roof panel A) having different width and length dimensions are set. Further, the number of the reinforcing members 1c in the frame 1 is set according to the width dimension of the frame 1. That is, the frame 1 is not limited to the shape shown in FIG.

A plate 1 is provided at each corner of the frame 1.
d are arranged and welded to the horizontal member 1a and the vertical member 1b, respectively.

At a predetermined position above the vertical member 1b of the frame 1, there is formed a hole 3 into which the bolt 6a is inserted when fixing the roof panel A to the roof frame. In addition, the lateral member 1a
Has a hole 4 for inserting a bolt 6a when it is connected to another vertically adjacent roof panel A, and a plurality of holes 5 for ventilation. In this embodiment, two holes 3 and four holes 4 are formed.

As the surface material 2, it is possible to selectively use a board such as a particle board or a wood wool cement board having a predetermined thickness and the width and length dimensions of the frame 1. In this embodiment, a wood wool cement board having a thickness of about 20 mm is used. Then, a roof panel A is constructed by integrally attaching a wood wool cement plate to the frame 1 with screws.

In the roof panel A constructed as described above,
A load acting vertically on the roof surface (a load acting vertically on the surface material 2) can be transmitted from the surface material 2 to the frame 1 and supported by the frame 1. For this reason,
The roof skeleton can be constructed by omitting the conventional rafters.

Further, since the surface material 2 is attached to the entire surface of the frame 1 in the roof panel A, it has a high rigidity against a force acting in parallel with the roof surface. The attached roof skeleton can exhibit high rigidity as a whole. Therefore, it is possible to omit the conventional brace and configure the roof skeleton.

When the roof panel A is attached to the roof frame, the surface material 2 can function as a base plate.

Next, the procedure for constructing the base of the roof by the roof panel A will be described with reference to FIGS. As shown in FIG. 3, the roof skeleton is provided with a plurality of columns or bundles 11, and beam members such as ridge beams 12, eaves beams 13 and purlins 14 are attached to the bundles 11 and climbing beams to positions corresponding to both ends of the roof.
It is configured by attaching 15 and omits rafters, braces, etc. such as the conventional roof frame.

Each eave beam 13 is provided with a bracket (not shown) for fixing the roof panel A, and the ridge beam 12 and the purlin 14 are provided with a mounting bracket 16 shown in FIG.

The roof panel A is erected on the roof frame 13
Install in parallel from the side. At this time, roof panel A
The lower end is fixed to a bracket provided on the eaves beam 13, and the upper end is fixed to a mounting bracket 16 provided on the purlin 14.

When the lower end of the roof panel A is fixed to the eaves beam 13, a bolt is inserted into the hole 4 formed in the lateral member 1a of the panel A, and the bolt is screwed into the bracket provided on the eaves beam 13. It is performed by fitting them together or by inserting them into the bracket and fastening them with nuts. When the upper end of the roof panel A is fixed to the mounting bracket 16 of the purlin 14, as shown in FIG. It is carried out by inserting it and fastening a nut 6b to the bolt 6a.

After the roof panel A is attached in parallel to the eaves side, another roof panel A is attached continuously to the ridge side of the roof panel A. In order to continuously attach the roof panel A to the ridge side of another roof panel A already attached, as shown in FIG. 4, the lower end of the roof panel A is attached to the purlin.
The bolt 6a is placed on the mounting bracket 16 provided on the panel 14, and the bolt 6a is inserted into the hole 4 formed in the transverse member 1a of the panel A and the other roof panel A already fixed, and the nut 6b is fastened to the bolt 6a. It is done by doing.

As described above, the roof panels A are sequentially mounted from the eaves side toward the ridge side, and the upper end of the uppermost roof panel A is attached to the mounting bracket 16 provided on the ridge beam 12 in the same manner as above. By fixing, it is possible to attach the roof panel A over the entire surface of the roof body.

[0028]

As described in detail above, in the roof panel according to the present invention, the surface material is integrally attached to the frame having the preset strength, so that the load applied to the roof surface can be sufficiently increased. It has high strength and high rigidity in the direction parallel to the roof surface. Therefore, when the roof panel is attached, the roof skeleton can exhibit sufficient strength and high rigidity. Therefore, it becomes possible to omit rafters and braces from the roof skeleton, and it is possible to reduce the types and the number of structural members.

When the roof panel is attached to the roof skeleton, the surface material exerts a function as a base plate. Therefore, when constructing the roof, carpentry work can be omitted, which reduces the number of jobs and simplifies the process.
The feature is that the process management can be simplified.
