Abstract

PURPOSE:To reduce the number of processes as well as prevent the enlargement of roof truss by a method in which a sheathing roof board is attached to the upside of parallel rafters along the sloped direction of roof and the eaves top house is attached to the tips of the rafters to make up a roof panel. CONSTITUTION:Sheathing roof boards 4 are attached in parallel with the sloped direction of roof on a frame fixed with parallel rafters 3 which are set between a horizontal part 1 set on the roof ridge side in parallel with the ridge direction and the eaves top house 2 attached to the eaves top in parallel with the part l to form a roof panel 5. The eaves back plate can thus be directly attached to the back of the rafters 3 without the needs to provide arm woods projected to the direction of eaves top and also to attach the base of the eaves back only by fixing the roof panels to the rafters 3 on the upside of the wooden house of the roof truss.

Description

Detailed Description of the Invention

[0001]

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

[0002]

BACKGROUND OF THE INVENTION Conventionally, as a roof panel to be mounted on a steel truss, a roof panel is attached to the upper surface of a purlin which is perpendicular to the upper chord of the truss. That is, by placing the purlin on the fixed portion of the upper chord member of the truss, the purlin is positioned in the roof direction and fixed to the fixed portion with bolts or the like.

[0003]

In the above-mentioned conventional roof panel, the main frame at right angles to the roof truss is used as the frame of the panel. Therefore, in the eaves protruding from the upper chord member of the roof truss, the floor plate is used. There is no skeleton to support the structure, or even if there is, there is only an eaves purlin that is not supported by a roof truss. Therefore, in the past, it was necessary to further project steel frame arms from the roof truss in the eaves direction. However, there has been a drawback that the number of construction man-hours is increased, or if the arm trusses are attached to the roof truss in advance, the large truss originally becomes larger. Further, in the past, since the eaves purlins were separately mounted after the panels were mounted, there was a drawback that the number of construction steps increased accordingly.

In addition, in the past, in order to mount the eaves back plate, a wooden base was previously attached to the steel frame arms and nailed to the base, so that the number of man-hours for constructing the eaves also increased. ..

The present invention eliminates these drawbacks and eliminates the need to provide armrests on the eaves, and a roof panel which can immediately strike the eaves backboard without attaching the base of the eaves. Is provided.

[0006]

In order to solve the above problems, according to the present invention, a field board is attached in advance to the upper surfaces of a plurality of parallel wooden rafters along the roof inclination direction, and the tip of each rafter is the eaves tip. It is characterized in that the eaves purlin is attached to the rafter tip as a unit.

[0007]

EXAMPLES FIGS. 3 and 4 show a method of constructing a roof using the roof panel of the present invention. First, as shown in FIG. 3, a truss (12) made of steel is mounted on the wall frame (11). Then, as shown in Fig. 4, the purlin (13) is placed on the truss (12).
After mounting, the roof panel (5) is mounted and fixed.

FIG. 1 shows a roof panel of the present invention. In the figure, (1) is a wooden cross bar arranged parallel to the roof ridge direction and on the roof ridge side, and (2) is the eaves tip. It is a wooden eaves purlin parallel to the transverse bar (1) attached to the side, and between the transverse bar (1) and the eaves purlin (2),
While fixing a plurality of wooden rafters (3) (3) in the roof inclination direction and parallel to each other, a plurality of field boards (4) are provided on the upper surface of the frame thus formed.
(4) are arranged side by side in the roof inclination direction and attached to form the roof panel (5) of the present invention.

FIG. 2 shows a mounting structure of the roof panel (5), which is a wooden purlin (13) (at the upper surface of the upper chord member (7) of the roof truss (12) at intervals in the roof inclination direction. 1
3) ... is installed and this purlin (13) (13)
The rafter (3) is placed and fixed on the upper surface of the. In this case, the rafters (3) are integrally formed up to the eaves direction. That is, the truss (6) does not need to be provided with arms that project toward the eaves, and the eaves backing plate or the like can be directly attached to the back surface of the rafter (3) without providing special arms. it can.

[0010]

As described above, according to the present invention, the rafter attached to the roof truss is integrated into the eaves side,
Since the eaves purlin is attached to the tip, it is not necessary to project the arms from the roof truss toward the eaves as in the conventional case, and it is possible to prevent the roof truss from increasing in size, or when mounting the arms on the site. There is an effect that the construction man-hour can be reduced as compared with. In addition, since the eaves purlins are pre-installed as one unit, the number of construction steps is reduced, and since the eaves back plate can be directly nailed to the back side of the wooden rafters, it is necessary to pre-construct the wooden base. There is an effect that there is no.
