Abstract

The invention discloses a bolt combination installation device and an application method. The bolt combination installation device comprises a screw rod, a nut and a positioning piece matched with the rod body; the screw rod consists of a rod body (the rod body is a cylindrical threaded rod body, or a threaded rod body with a plane section, or a threaded rod body with a notch), a countersunk head; the countersunk head is completely or partially protruded outside the combination formed by the rod body and the positioning piece. By arranging the positioning piece matched with the rod body and the countersunk head, the bolt combination installation device disclosed by the invention can be effectively fixed on a wall body or a decorative panel to realize the functions of the conventional back bolt; the bolt combination installation device is simple in structure and convenient to construct and operate, and has great practicability.

Description

technical field [0001] The invention belongs to the field of building decorative materials, and relates to a bolt combination installation device and an application method, in particular to a bolt combination installation device and an application method which increase stability by effectively combining a positioning member with a screw rod. Background technique [0002] The back bolt structure is an installation method that drills a blind hole at a certain position from the surface of the material, puts the back bolt into the blind hole, and makes the back bolt and the material tightly connected. The stone structure used in China mostly uses blind holes on the surface of the material and inserts expansion back bolts with notches. Since the axial dimension of the notch in the expansion part is small, the contact distance between the notch and the blind hole of the material is very short, and the tensile strength is limited. Restrictions, the joints of the back tie are easy t...
