Building frame

Abstract

A ridge is directly supported by a ridge supporting post that is erected on a floor plane of a floor right below a gable roof to provide a stable building frame having a pentagon shape in front view and furthermore to realize a beamless space where no lower chord member such as a roof beam extends above the floor right below the gable roof. Also, a tall window extending continuously toward the vicinity of the ridge is provided between the ridge supporting post of a gable end wall and each of gable end side sub-pillars erected on both sides of the ridge supporting post. Thus, a living space gives a feeling of spaciousness and openness in spite of a compact appearance of a building.

1 . A building frame having a pentagon shape in front view and including a gable end wall on at last one side of a gable roof included, as at least a part of a roof, in a wooden building, the building frame comprising:
 a floor plane provided on a floor right below the gable roof so as to have a rectangle shape in plan view;   corner posts respectively erected on four corners of the floor plane;   a pair of pole plates facing each other, each of the pair of pole plates connecting upper ends of the corner posts in a ridge direction;   a plurality of sloping beams respectively placed from each of the pair of pole plates to a ridge of the gable roof at appropriate intervals in a manner of making a vertex of a triangle;   a ridge pole connecting upper ends of the sloping beams;   a ridge supporting post erected on the floor plane, on a position that is right below the ridge and that includes the gable end wall on the at last one side of the gable roof, the ridge supporting post supporting the ridge pole on the floor plane; and   gable end side sub-pillars erected on the floor plane, on both left and right sides of the ridge supporting post of the gable end wall at appropriate intervals so as to support a pair of sloping beams that is on the gable end wall out of the plurality of sloping beams, wherein   a window with an opening area from the floor plane to a gable height of the gable end wall is provided between the ridge supporting post of the gable end wall and each of the gable end side sub-pillars, and   the ridge supporting post bears vertical load that acts on the gable roof so as to form, on the floor plane, a beamless space where no lower chord member of a roof truss constituting the gable roof extends.   
     
     
         2 . The building frame according to  claim 1 , wherein
 a reinforcing surface plate is provided, in a tense state, on each part sandwiched between one of the corner posts of the gable end wall and the corresponding one of the gable end side sub-pillars.   
     
     
         3 . The building frame according to  claim 1 , wherein
 the floor plane of the floor right below the gable roof is supported by a floor beam of the floor right below the gable roof, the floor beam being provided to surround four sides of the floor plane, and   a floor plane of a lower floor is provided lower than the floor plane of the floor right below the gable roof so as to be shifted by a substantially half story height or less, and the floor plane of the lower floor is supported by a floor beam of the lower floor.   
     
     
         4 . The building frame according to  claim 1 , wherein
 a reinforcing surface plate is put between one of the pair of sloping beams on the gable end wall and an adjacent sloping beam thereto so that the reinforcing surface plate is attached to both the sloping beams.
