Fastening device

Abstract

A fasting device that fastens a supporting member such as a foundation plate ( 42 ) to a connecting member such as a pillar ( 51 ) is composed of a bearing body ( 11 ), shock absorbing bodies ( 38 ), anchoring implements ( 55 ), etc. The bearing body ( 11 ) is disposed at the center of a space (S) where the supporting member and the connecting member face each other, and comprises a basic plate ( 12 ) which is in surface contact with the supporting member, a mounting plate ( 14 ) which is in surface contact with the connecting member, and connecting sections which connect both of these plates. The shock absorbing bodies ( 38 ) are formed using U-shaped leaf springs or the like, and are disposed at the outer edges of the space (S) where the supporting member and the connecting member face each other. Reaction forces are generated in the shock absorbing bodies ( 38 ) according to the displacement of the connecting member or the like.

1 . A fastening device for fastening a supporting member and a connecting member that are adjacent to each other such as a pair of a foundation plate ( 42 ) and a pillar ( 51 ) or a pair of a pillar ( 51 ) and a cross beam ( 59 ), comprising:
 a bearing body ( 11 ) disposed in a space (S) in which the supporting member and the connecting member face each other;   a plurality of shock absorbing bodies ( 38 ) disposed near outer rims in the space (S);   anchoring implements ( 55 ,  58 ) embedded in the supporting member and/or the connecting member to fix the bearing body ( 11 ) and the shock absorbing body ( 38 ); and   a bolt ( 54 ) for fixing the bearing body ( 11 ) and the shock absorbing body ( 38 ),   wherein the bearing body ( 11 ) includes a basic plate ( 12 ) that is in surface contact with the supporting member, a mounting plate ( 14 ) that is in surface contact with the connecting member, and a connecting section connecting the basic plate ( 12 ) and the mounting plate ( 14 ) in substantially center of the space (S), and   the shock absorbing body ( 38 ) has elasticity to generate reaction force in accordance with displacement of the space (S), one end of the shock absorbing body ( 38 ) is fixed to the basic plate ( 12 ) or any of the anchoring implements ( 55 ,  58 ) in the supporting member, and the other end is fixed to the mounting plate ( 14 ) or any of the anchoring implements ( 55 ,  58 ) in the connecting member.   
     
     
         2 . The fastening device according to  claim 1 , wherein the connecting section comprises:
 a lower arm ( 21 ) projected from the basic plate ( 12 );   an upper arm ( 23 ) projected from the mounting plate ( 14 ); and   a pin ( 22 ) penetrating the lower arm ( 21 ) and the upper arm ( 23 ) and axially supporting the basic plate ( 12 ) and the mounting plate ( 14 ) so as to be rotatable.   
     
     
         3 . The fastening device according to  claim 1 , wherein the shock absorbing body is a stud bolt ( 38   d ) in which a left screw is used at one end and a right screw is used at the other end, and internal screws ( 62 ,  65 ) in which the stud bolts ( 38   d ) are screwed are provided in outer rims of the basic plate ( 12 ) and the mounting plate ( 14 ). 
     
     
         4 . The fastening device according to  claim 1 , wherein the shock absorbing body is a shaft ( 38   e ) having a flange-shaped or groove-shaped step part ( 37 ) in a side peripheral face near both ends, and a restrainer ( 72 ) retaining the stepped part ( 37 ) is provided in outer rim of each of the basic plate ( 12 ) and the mounting plate ( 14 ). 
     
     
         5 . The fastening device according to  claim 2 , wherein the shock absorbing body is a stud bolt ( 38   d ) in which a left screw is used at one end and a right screw is used at the other end, and internal screws ( 62 ,  65 ) in which the stud bolts ( 38   d ) are screwed are provided in outer rims of the basic plate ( 12 ) and the mounting plate ( 14 ). 
     
     
         6 . The fastening device according to  claim 2 , wherein the shock absorbing body is a shaft ( 38   e ) having a flange-shaped or groove-shaped step part ( 37 ) in a side peripheral face near both ends, and a restrainer ( 72 ) retaining the stepped part ( 37 ) is provided in outer rim of each of the basic plate ( 12 ) and the mounting plate ( 14 ).
