Description

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

[Prior Art] Conventionally, a rooftop structure of a building supporting a pitched roof is disclosed in Japanese Patent Laid-Open No. 53-
As described in Japanese Patent No. 70519, a plurality of triangular hut trusses are fixed in parallel on the beam upper part of the building body, a mist is passed between the hut trusses, and roofs are placed on the hut trusses. The panel is fixed.

[Problems to be Solved by the Invention] However, in the above-described conventional shed group, since a plurality of shed trusses are installed in parallel, the shed is cut off in the direction orthogonal to the flow of the pitched roof, resulting in an attic. It is difficult to secure a wide and continuous attic that can be effectively used as a room.

Further, in the above-mentioned conventional shed assembly, it is necessary that the vertical frame material of the roof panel and the upper chord material of the shed truss be overlapped and extended, and that huts connecting the shed trusses to be connected be provided. A large amount of constituent material that exceeds the degree required to ensure strength is used. This is not appropriate because it causes an excessive load on the building body on which the shed is mounted and also increases the cross section of the building material.

Further, in the above-mentioned conventional shed construction, since the load of the shed construction is supported by the beams of the building body, it is not appropriate because the beam cross section must be enlarged.

Also, since the hut truss and spigot were joined at the construction site and the roof panel was fixed to the hut truss, a lot of construction man-hours were required.

An object of the present invention is to form a wide continuous attic, reduce the number of constituent members of a shed, reduce the cross section of constituent members of a building body, and reduce the number of construction steps at a construction site.

[Means for Solving the Problems] The building shed assembly 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 composed of a plurality of building units, the building unit is a combination of floor beams, columns, and ceiling beams, and the roof support member is at least an upper chord member, a vertical member, and a diagonal member. It is combined with the mold, the diagonal members are made of shaped steel and are joined to the middle part of the upper chord members and the lower ends of the vertical members, the roof panel has vertical frame members, and the roof support members are used for the flow of slope roof. The vertical members of the roof support member are arranged along the direction orthogonal to each other at positions corresponding to the pillars of the building body, and the vertical frame members of the upper chord member roof panel are supported.

[Operation] According to the present invention, the substantially gate-shaped roof support member is arranged in the direction orthogonal to the flow of the pitched roof, and the diagonal member is joined to the middle portion of the upper chord member and the lower end portion of the vertical member. Therefore, the attic is not broken in the direction orthogonal to the flow of the sloped roof, and it is possible to form a wide and continuous attic that can be effectively used as an attic or the like.

Further, according to the present invention, the vertical frame member of the roof panel is orthogonal to the roof supporting member, the vertical frame member of the roof panel and the upper chord member of the roof supporting member do not overlap each other, and the adjacent roof supporting member is roofed. It will be connected by the vertical frame material of the panels. Therefore, it is possible to reduce the number of components of the shed.

Further, according to the present invention, the weight of the shed member is reduced by reducing the constituent members of the shed member as described above, and the load of the shed member passes through the vertical member or the diagonal member of the roof support member and the building main body. The beam cross section of the building body can be miniaturized because it is supported by the pillars in a flowing state. Therefore, the cross section of the building material can be reduced.

Furthermore, since the main body of the building is composed of a plurality of building units, and the roof of the building is composed of the roof support member, the ceiling beams of the building unit, and the vertical frame material of the roof panel, the number of construction man-hours at the construction site can be reduced. .
