Construction joints

Abstract

This product is an architectural fastening fitting that joins (connects) a pillar and a beam; for example, as shown in the reference diagram showing the state of use, the connecting base part of this product is attached to the side of the pillar, the connecting protruding plate part protruding from this connecting base part is inserted into the slit part of the joint part at the tip of the beam, and a drift pin is driven through the connecting hole of this connecting protruding plate part to join the pillar and the beam. Furthermore, as shown in the reference diagram showing the state of use, two of these items are arranged in a multiple locking state, one above the other, and the drift pin (locking pin) also passes through the locking device penetration gap (locking hole) formed by the upper locking edge of the lower architectural connecting fitting (this item) and the opposing lower locking edge of the upper architectural connecting fitting (this item).Even if a force that tries to rotate each connecting fitting due to shear force is generated in each fitting and secondary stress is generated in the drift pin, by locking it with this locking pin, the secondary stress generated in opposite directions at the top and bottom is canceled out, reducing the number of drift pins that generate secondary stress, and preventing a decrease in the rigidity of the joint due to the suppression of rotation.This is an architectural connecting fitting configured in this way.
