Load Bearing Frame

Abstract

The present invention is to provide a load bearing frame for suppressing generation of buckling of diagonal materials and breakage of connection parts and having high deformability. A load bearing frame 1 has two pillar materials 2 and 3 , two frame materials 4 and 5 and four diagonal materials 6 to 9 . A connection point 41 between the pillar material 3 and the frame material 4 is apart from a connection point 43 between the diagonal material 6 arranged on the uppermost side and the pillar material 3 by a distance L 1 . A connection point 48 between the pillar material 3 and the frame material 5 is apart from a connection point 47 between the diagonal material 9 arranged on the lowermost side and the pillar material 3 by a distance L 2.

1 . A load bearing frame having a first pillar material, a second pillar material, a first frame material for connecting one ends of said first pillar material and said second pillar material respectively, and a second frame material for connecting the other ends of said first pillar material and said second pillar material respectively, wherein
 a first diagonal material for connecting a connection position which is other than both the ends of said first pillar material and a position which is other than both the ends of said second pillar material close to the one end of said second pillar material in comparison with the connection position, and a second diagonal material for connecting a connection position which is other than both the ends of said first pillar material and a position which is other than both the ends of said second pillar material close to the other end of said second pillar material in comparison to the connection position are provided with regard to one or more connection position, and   a connection point between said first diagonal material arranged closest to the one end of said second pillar material and said second pillar material is apart from a connection point between said second pillar material and said first frame material, and a connection point between said first diagonal material arranged closest to the other end of said second pillar material and said second pillar material is apart from a connection point between said second pillar material and said second frame material.   
   
   
       2 . The load bearing frame according to  claim 1 , wherein a distance between the connection point between said first diagonal material arranged closest to the one end of said second pillar material and said second pillar material and the connection point between said second pillar material and said first frame material, and a distance between the connection point between said first diagonal material arranged closest to the other end of said second pillar material and said second pillar material and the connection point between said second pillar material and said second frame material are distances corresponding to 5 to 20% of the entire length of said second pillar material. 
   
   
       3 . The load bearing frame according to  claim 1 , further comprising a reinforcing material for connecting a position which is other than both ends of said first frame material and a position which is other than both ends of said second frame material, the reinforcing material being jointed to said first diagonal material and said second diagonal material. 
   
   
       4 . The load bearing frame according to  claim 1 , further comprising connection members arranged between said first and second pillar materials and said first and second diagonal materials, the connection members being fixed to said first and second pillar materials at fixing positions apart from pillar corner parts of said first and second pillar materials towards the inside. 
   
   
       5 . The load bearing frame according to  claim 4 , wherein a distance between the pillar corner parts of said first and second pillar materials and the fixing positions are distances corresponding to 20 to 30% of width of side surfaces of said first and second pillar materials. 
   
   
       6 . The load bearing frame according to  claim 2 , further comprising a reinforcing material for connecting a position which is other than both ends of said first frame material and a position which is other than both ends of said second frame material, the reinforcing material being jointed to said first diagonal material and said second diagonal material. 
   
   
       7 . The load bearing frame according to  claim 2 , further comprising connection members arranged between said first and second pillar materials and said first and second diagonal materials, the connection members being fixed to said first and second pillar materials at fixing positions apart from pillar corner parts of said first and second pillar materials towards the inside. 
   
   
       8 . The load bearing frame according to  claim 3 , further comprising connection members arranged between said first and second pillar materials and said first and second diagonal materials, the connection members being fixed to said first and second pillar materials at fixing positions apart from pillar corner parts of said first and second pillar materials towards the inside. 
   
   
       9 . The load bearing frame according to  claim 6 , further comprising connection members arranged between said first and second pillar materials and said first and second diagonal materials, the connection members being fixed to said first and second pillar materials at fixing positions apart from pillar corner parts of said first and second pillar materials towards the inside. 
   
   
       10 . The load bearing frame according to  claim 7 , wherein a distance between the pillar corner parts of said first and second pillar materials and the fixing positions are distances corresponding to 20 to 30% of width of side surfaces of said first and second pillar materials. 
   
   
       11 . The load bearing frame according to  claim 8 , wherein a distance between the pillar corner parts of said first and second pillar materials and the fixing positions are distances corresponding to 20 to 30% of width of side surfaces of said first and second pillar materials. 
   
   
       12 . The load bearing frame according to  claim 9 , wherein a distance between the pillar corner parts of said first and second pillar materials and the fixing positions are distances corresponding to 20 to 30% of width of side surfaces of said first and second pillar materials.
