Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a roof frame for a building.

[Prior art] Conventionally, roof frames for buildings that support pitched roofs have been developed in accordance with Japanese Patent Application Laid-Open No.
- As described in Publication No. 70519, a plurality of triangular shed trusses are fixed in parallel on the upper part of the beam of the building body, and mist is passed between each shed truss, Fixing roof panels.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional roof structure, since a plurality of shed trusses are installed in parallel, the attic is cut into sections in the direction perpendicular to the flow of the pitched roof. It is difficult to secure a large and continuous attic space that can be effectively used as a room.

In addition, in the conventional roof truss mentioned above, the vertical frame material of the roof panel and the top chord of the shed truss overlap and extend, and a moat is required to connect each shed truss, making the roof truss unnecessary. A larger amount of structural material will be used than is necessary to ensure strength. This is not appropriate because it would impose an excessive load on the building body on which the roof frame is mounted, and it would also increase the cross-section of the building body's constituent materials.

In addition, in the conventional shed set 0, the front claws of the shed set are supported by the beams of the building body, so it is necessary to increase the cross section of the beams, which is not appropriate.

The present invention aims to form a wide and continuous attic, reduce the number of constituent materials of the roof frame, and reduce the cross section of the constituent materials of the building body.

[Means for Solving the Problems] The present invention provides a roof assembly for a building that supports a pitched roof by fixing a roof support member to the top of a building body having columns, fixing a roof panel to the top of the roof support member, and , the roof support member is formed by combining at least an upper chord member, a vertical member, and a diagonal member in a substantially gate shape, and the roof support member is arranged along a direction perpendicular to the flow of the sloped roof, The vertical members of the members are placed at positions corresponding to the pillars of the building body.

[Function] According to the present invention, since the substantially gate-shaped roof support member is arranged in the direction perpendicular to the flow of the sloped roof, the small jlJ does not break in the direction perpendicular to the slope of the sloped roof. , it is possible to form a wide and continuous attic that can be effectively used as a roof damage room, etc.

Further, according to the present invention, the vertical frame members of the roof panel are perpendicular to the roof support members, the vertical frame members of the roof panel and the upper chord members of the roof support members do not overlap, and the adjacent roof support members are They will be connected by the vertical frame material of the panels. Therefore, the number of constituent materials for the roof frame can be reduced.

Further, according to the present invention, (1) the weight of the roof frame is reduced by reducing the number of constituent materials of the roof frame as described above, and (2) the load of the roof frame is transferred to the building body through the vertical members of the roof support members. Since the beams are supported by the pillars in a flowing manner, the beam cross section of the building body can be made smaller.

Therefore, the cross section of the building body can be reduced.
