Building structure

Abstract

An architectural structure 1 A includes architectural frameworks 4 obtained by mutually joining bent architectural members 2 in which horizontal frame portions 11 and longitudinal frame portions 13 continue into each other upon being bent in a substantially right-angular manner with arc-like portions 12 interposed therebetween. The architectural framework 4 includes a planar base portion 3 in which horizontal frame portions 11 continue into each other and in which joint portions P project out by sequentially joining the longitudinal frame portions 13 by using joint portions P with multiple surface connecting portions P 1 for joining at least the longitudinal frame portions 13 while facing each other at multiple surfaces of not less than three surfaces.

1 . An architectural structure, characterized in that it comprises architectural frameworks in which bent architectural members, each of which includes, in a successive manner, a horizontal frame portion and a longitudinal portion that succeeds from an end portion of the horizontal frame portion through an arc-like portion and that bends in a substantially right-angular manner with respect to the horizontal frame portion, are arranged in that joint portions including a multiple surface connecting portions for joining at least the longitudinal frame portions while facing each other at multiple surfaces of not less than three surfaces are used for sequentially joining the longitudinal frame portions so as to comprise a planar base portion in which the horizontal frame portions continue into each other and in which the joint portions are projecting out.  
   
   
       2 . The architectural structure as claimed in  claim 1 , wherein the bent architectural member assumes a substantially U-like shape with the longitudinal frame portions being provided at both ends of the horizontal frame portion.  
   
   
       3 . The architectural structure as claimed in  claim 1  or  2 , wherein the horizontal frame portion is either straight-linear or has a curved shape with a large radius of curvature.  
   
   
       4 . The architectural structure as claimed in  claim 1 , wherein the architectural framework is provided, at the base portion, with a retention frame material for shape retention for retaining the shape of the base portion that is fixed at the horizontal frame portion at a surface of the horizontal frame portion opposite to the joint portion.  
   
   
       5 . The architectural structure as claimed in  claim 4 , wherein the architectural framework is arranged in that wood sheathings for floors or roofs are attached to the base portion with the retention frame material interposed therebetween.  
   
   
       6 . The architectural structure as claimed in  claim 1 , wherein the multiple surface joint portion is interposed with filler materials between a plurality of opposing longitudinal frame portions.  
   
   
       7 . An architectural structure, characterized in that it comprises an architectural framework in which bent architectural members, each of which includes, in a successive manner, a horizontal frame portion and a longitudinal portion that succeeds from an end portion of the horizontal frame portion through an arc-like portion and that is bent with respect to the horizontal frame portion, are arranged in that joint portions for double surface connection for joining the frame portions at two surfaces back to back for sequentially joining the frame portions so as to comprise a planar base portion in which the frame portions continue into each other and in which the joint portions are not projecting out.  
   
   
       8 . The architectural structure as claimed in  claim 7 , wherein the bent architectural members form ring-like bodies of polygonal shape including triangles, and outward facing surfaces of the ring-like bodies are mutually joined as facing surfaces to comprise the architectural framework.  
   
   
       9 . The architectural structure as claimed in  claim 8 , wherein the ring-like body is arranged in that at least one outward facing surface thereof is inclined with respect to a central line of the ring-like body.  
   
   
       10 . The architectural structure as claimed in  claim 8 , wherein the ring-like bodies are joined such that their outward facing surfaces are parallel to a central line of the ring-like bodies while interposing interposing members, which include two tapered sloped surfaces, between the facing surfaces.  
   
   
       11 . The architectural structure as claimed in  claim 7 , wherein the bent architectural members are joined through dovetail joint in which dovetail tenons are fitted into dovetail grooves that are provided on the facing surfaces.  
   
   
       12 . The architectural structure as claimed in  claim 11 , wherein the dovetail joint is performed through joining the dovetail tenon in a closely fitted manner into the dovetail groove upon expanding a width of the dovetail tenon, which is dividable in a width direction of the dovetail groove and which has a width that is smaller than a minimum width of the dovetail groove, through a placing tool.
