Vibration-absorption type eccentric back bolt and mounting method
The invention discloses a vibration-absorption type eccentric back bolt and a mounting method. The vibration-absorption type eccentric back bolt and mounting method comprises a countersunk bolt, an eccentric pipe, a vibration-absorption sleeve, a nylon gasket and a nut, wherein the diameter, the height and the taper of the head of the countersunk bolt are matched with those of a tapered wedged hole groove chambered in the bottom of a decoration board back bolt hole; the eccentric pipe is a back bolt hole sleeve piece; the outer diameter and the height of the eccentric pipe are adapted to those of a back bolt straight hole; an eccentric through hole is formed in a flat end face; the hole diameter of the eccentric through hole is matched with a screw rod of the countersunk bolt in a penetrating manner; the vibration-absorption sleeve is a flexible thin film sleeve which covers the outer surface of the eccentric pipe and is in contact with a back bolt hole wall. The vibration-absorption type eccentric back bolt is a stone decoration board bolt with a novel structure, which comprehensively utilizes a mechanical eccentric and flexible buffering performance principle. The mounting method is finished by the following steps: drilling a back hole in a decoration board; carrying out tapered chambering; cleaning powder; injection glue into the bottom of the hole (or blending glue on the head of the bolt); putting the bolt; putting the eccentric pipe; mounting a hanging piece; adding the gasket; screwing on the nut and the like. The vibration-absorption type eccentric back bolt is low in cost and is convenient to mount, and has no stress and no damage to the decoration board; meanwhile, the vibration-absorption type eccentric back bolt has a good vibration-absorption performance, is safe and reliable to use and can be widely applied to dry-hanging construction of various veneers.
