Connection device for connection of building members and building

Abstract

A connection device for connection of building members, and a building comprising members thus connected, exhibiting innovative function and effect which have not been found in the prior art. The connection device for connection of vertical members and horizontal members which comprise a building consists of a base body on which second connection portions are provided to be connected to first connection portions provided on building members such as vertical members, horizontal members, the first connection and the second connection being connected to each other by a first fitted annular body to be fitted by groove contact onto edges of both the first connection portion and the second connection portion, and a second fitted annular body adapted to be taper press fitted onto the first fitted annular body.

What is claimed is:  
     
         1 . A connection device for connection of building members, such as vertical members and horizontal members, which comprise a building, the connection device comprising a base body on which are provided second connection portions to be connected to first connection portions provided on building members such as the vertical members and the horizontal members, the first connection portion and the second connection portion being connected to each other by a first fitted annular body to be fitted by groove contact onto edges of both the first connection portion and the second connection portion, and a second fitted annular body which is taper press fitted onto the first fitted annular body.  
     
     
         2 . The connection device according to  claim 1 , wherein the second connection portions are provided in two or more locations on the base body.  
     
     
         3 . The connection device according to  claim 1  or  2 , wherein the base body, second connection portions, building members, and the first connection portions are hollow members.  
     
     
         4 . A building, wherein building members such as vertical members and horizontal members are connected together by the connection device according to any one of  claims 1  to  3  to form a frame.  
     
     
         5 . The connection device according to  claim 3 , wherein the building members are hollow bodies having a square cross sectional shape in a direction perpendicular to a longitudinal direction.  
     
     
         6 . The connection device according to  claim 3  or  4 , wherein inner holes of the building members are circular in the section perpendicular to the longitudinal direction.  
     
     
         7 . The connection device according to  claim 3 ,  5  or  6 , wherein the building members are formed from concrete.
