Abstract

Provided is a direction-adjustable bolted spherical joint for collapse resistance and earthquake resistance. The joint includes a connecting component, disposed between a bolt ball and a member. The connecting component includes a threaded barrel, the threaded barrel is screwed into a connecting hole on the bolt ball, a connecting rod is clamped into the threaded barrel, a threaded cap is screwed onto the connecting rod, and an end of the threaded cap facing towards the threaded barrel is embedded into the threaded barrel. The connecting rod includes a ball head, the ball head is abutted against an end of the threaded barrel disposed in the bolt ball, the ball head is fixedly connected to a rod body, the rod body is disposed to pass through the threaded barrel and extend out of the bolt ball, and the threaded cap is screwed onto the rod body.

Claims (18)
