Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof frame panel having a steel frame.

[0002]

2. Description of the Related Art It has been considered that a roof panel is composed of a frame-shaped steel frame and a field plate attached to the surface of the steel frame, and braces are provided in advance in the steel frame. That is, the entire panel is formed in a rectangular shape or a square shape, X-shaped braces are arranged in the steel frame, and the horizontal load is supported by the braces.

[0003]

As described above, by providing the brace on the roof panel in advance, there is an advantage that the construction of the brace on the site is unnecessary. However, in a gabled roof where the roof surface is all square, the roof panels can also be made all square or square, and it is only necessary to place braces between the diagonal corners. When the roof panel is transported or formed into a size that can be transported, it must be a polygon with five or more sides, and in some cases braces cannot be provided. Therefore, the horizontal load cannot be sufficiently supported. There is a drawback. For example, in a hipped roof as shown in FIG. 4, both sides of the large ridge 21 are rectangular and the brace 22 can be provided in an X shape. , Divided into triangular panels 25, resulting in areas where braces cannot be provided. Of these, especially the pentagonal panel 23,
Since there is no diagonal diagonal member, bearing capacity for horizontal load becomes a problem.

An object of the present invention is to solve the above-mentioned conventional drawbacks so that a horizontal roof load can be supported even in a frame of a roof panel having a polygonal shape with five or more sides, in a hipped roof. And

[0005]

In order to solve the above problems, according to the present invention, a frame-shaped steel frame having five or more sides is divided into a rectangular or square portion and a triangular or trapezoidal portion, and Arrange the crosspieces along the boundary of. In addition, X between the diagonals of the rectangle or square
The braces are arranged in a circular shape, and the diagonal members are arranged between a pair of diagonals of the trapezoidal portion.

[0006]

By adding diagonal members to the trapezoidal portion without braces, the diagonal members act as resistance to horizontal loads, so even in a polygonal frame with five or more sides, sufficient resistance to horizontal loads is provided. You can have power.

[0007]

1 and 2 show a pentagonal frame and a roof panel having the frame according to an embodiment of the present invention. In the figure, 1a and 1b are a pair of Cs that are arranged along the roof inclination direction and are parallel to each other and have different lengths.
It is a vertical frame composed of channels, and a horizontal frame 2 also composed of C channels is connected across the end portions of the vertical frames 1, 1 on the eaves side. In addition, arms 3 and 3 are preliminarily fixed to the ends of the vertical frames 1a and 1b on the eaves side so as to overlap the upper surfaces thereof, and the tips of the arms 3 and 3 project in the eaves direction.
Further, one lateral frame 4 is attached so as to straddle between the arms 3 and 3 near the tips thereof. Between the ridge-side tips of the vertical frames 1a and 1b, they are connected to each other via a horizontal frame 5 and a slant frame 6 in a direction perpendicular to the vertical frames 1a and 1b, and as a result, as a whole. It forms a pentagon.

In this embodiment, first, the crosspiece 7 made of a C channel is connected across the tip of one of the shorter vertical frames 1b and the intermediate portion of the other vertical frame 1a. Braces 8, 8 are attached in an X shape across the diagonal corners of a square or rectangular portion surrounded by the crosspiece 7 and the horizontal frame 2 and the vertical frames 1a, 1b parallel thereto. .. Further, the trapezoidal portion divided by the crosspiece 7 is provided with a diagonal member 9 composed of a C channel extending over one diagonal corner so that the trapezoidal portion can also support a horizontal load. Is configured.

Incidentally, as shown in FIG.
A base plate 12 is attached to the upper surface of 0 through a wooden purlin 11.

FIG. 3 shows the position of the roof panel mounting structure as described above. The trusses 13 and 14 of mountain type or trapezoidal type are mounted on the wall frame 12 and the truss 1
The pentagonal roof panel 15 and the triangular roof panel 16 of the present invention, or the above-mentioned pedestal roof panel, etc. are mounted on the panels 3 and 14 to form a roof.

[0011]

As described above, according to the present invention, the square or rectangular portion partitioned by the crosspieces is provided with braces in an X shape so as to have a supporting force for a horizontal load. By inserting diagonal material into another trapezoidal part partitioned by, the diagonal material of that part acts as resistance to horizontal load, so
As described above, even if the ridge roof cannot be formed in a rectangular shape, there is an effect that the entire roof can have a sufficient horizontal supporting force.
