Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a roof truss of a building.

[Prior Art] Conventionally, the roof of a building is actually installed in the upper part of the building body.
A roof truss as described in Japanese Patent No. 612 is fixed, and a roof panel is fixed to the upper part of the roof truss. At this time,
The roof truss has great rigidity and can secure the proof stress required for the roof truss.

[Problems to be Solved by the Invention] However, since the roof truss that constitutes the above-mentioned conventional roof truss is provided with high rigidity, it is composed of a combination of an upper chord member, a lower chord member, a vertical member, and a diagonal member. Composed of components. This means that an excessive load due to many components is applied to the main body of the building where the shed is mounted, and the cross section of the components such as columns and beams of the main body is enlarged, which is appropriate. Not.

An object of the present invention is to reduce the number of constituent members of the roof truss and the cross section of the constituent members of the building main body under the condition of ensuring the proof stress required for the roof truss.

[Means for Solving the Problems] The building roof structure of the present invention supports a pitched roof in which a roof support member is fixed to the upper part of the building body and a roof panel is fixed to the upper part of the roof support member. In a rooftop structure of a building, the main body of the building is a combination of columns and ceiling beams, the roof support member is a combination of upper chord members, vertical members, and diagonal members in a substantially gate shape, and the diagonal members are formed from shaped steel. Both ends are joined to the middle part of the upper chord member and the lower end of the vertical member, the roof panel has a vertical frame member, and the vertical member of the roof support member is arranged at a position corresponding to the pillar of the building body, The members are placed along the beams of the building body and along the direction orthogonal to the flow of the sloped roof, and at the middle part of the upper chord and at or near the part where the diagonal members are joined, the vertical frame material of the roof panel. Is to support.

[Operation] According to the present invention, by arranging the roof support member along the beam of the building body, the beam can function as a member corresponding to the lower chord member of the roof support member. That is, the roof support member forms a truss structure having high rigidity together with the beam of the building body, although it does not include the lower chord member.
The diagonal members are made of shaped steel and both ends are joined to the middle part of the upper chord member and the lower end of the vertical member.The vertical frame of the roof panel is at the middle part of the upper chord member or at the vicinity where the diagonal members are joined. Since the member is supported, the load of the roof panel is supported in a state where the load of the roof panel flows to the pillar of the building body through the vertical member or the diagonal member of the roof supporting member. Therefore, according to the present invention, it is possible to use the roof support member without the lower chord member under the condition of ensuring the proof strength required for the rooftop structure, so that the number of constituent materials of the rooftop structure can be reduced and the building main body can be reduced accordingly. It is also possible to reduce the cross-section of constituent materials such as columns and beams.

According to the above embodiment, the roof support members 18, 19 are attached to the building main body 11
The beam 16 can be made to function as a member corresponding to the lower chord member of the roof support members 18 and 19 by arranging the beam 16 along the ceiling beam 16. That is, the roof support members 18 and 19 are integrated with the beam 16 of the building body 11 to form a truss structure having high rigidity, although they do not include the lower chord member. Also, diagonal member 26,
29 is formed from a shaped steel, both ends of which are joined to the middle part of the upper chord members 24 and 27 and the lower ends of the vertical members 25 and 28, and the middle portion of the upper chord members 24 and 27 where the diagonal members 26 and 29 are joined. Since the vertical frame member 21 of the roof panel 20 is supported by, the load of the roof panel 20 flows to the pillar 15 of the building body 11 through the vertical members 25 and 28 of the roof supporting members 18 and 19 or the diagonal members 26 and 29. Supported. Therefore, according to the above-mentioned embodiment, under the condition of ensuring the proof strength necessary for the shed 12, the roof support members 18 and 19 without lower chord members are provided.
Since it is possible to use the above, it is possible to reduce the number of constituent materials of the shed 12 and accordingly reduce the cross section of the constituent elements of the pillars 15, the beams 14, 16 and the like of the building body 11.

[Effects of the Invention] As described above, according to the present invention, it is possible to reduce the number of constituent members of the roof truss and the cross section of the constituent members of the building main body under the condition that the yield strength necessary for the truss troop is secured. .
