A stone secret door with a rotating shaft mechanism and its installation method

Abstract

The invention discloses a stone blank door with novel rotating shaft mechanisms and an installation method of the stone blank door. The stone blank door comprises a stone door leaf, a stone door steel skeleton, a stone veneer steel skeleton and the two rotating shaft mechanisms, wherein the stone door leaf is matched with the installation position of a stone veneer blank door; the two rotating shaft mechanisms are connected with the back surface of the stone door leaf and the stone veneer steel skeleton; the stone door steel skeleton is fixed on the back surface of the stone door leaf; a steel upright post and an inner wall behind a stone veneer are fixed at an interval through a corner connector; a screw rod of each embedded bolt respectively passes through a mounting hole of a square tube of the corresponding rotating shaft mechanism, and then is locked and fixed with a connecting nut; a screw rod on the bolt of each rotating shaft mechanism passes through a mounting groove in the corresponding steel angle beam, and is locked through an upper positioning nut and a lower positioning nut; the rotating shaft mechanisms at the upper end and the lower end of the stone door leaf are positioned on the same vertical axis. According to the stone blank door disclosed by the invention, the space between the stone veneer and the stone veneer steel skeleton is cleverly and fully utilized, so that the stone blank door is relatively flexible, smooth and free of a sound when the stone door leaf is closed or opened; the support on the stone door leaf is relatively stable; the service life is prolonged.

Description

technical field [0001] The invention relates to the field of architectural decoration secret doors, in particular to a stone secret door with convenient disassembly and assembly, long service life, smooth opening and closing, a novel rotating shaft mechanism and an installation method thereof. Background technique [0002] At present, in decoration engineering projects, the halls and lobbies of buildings or hotels are mostly decorated with stone veneer. There will be doors in these halls or lobbies. In order to maintain the consistency of the stone veneer of the hall or lobby, the doors must be made Stone secret door. Common practice (such as figure 1 shown) is to weld the round steel or steel pipe 910 on the steel frame and connect the casing 920 reserved on the stone door leaf to form the door shaft. The combination is not tight, there is a large gap, the gap between the door and the stone wall is difficult to effectively control and shift, and it is easy to cause collis...

AI Technical Summary

Problems solved by technology

Common practice (such as figure 1 shown) is to weld the round steel or steel pipe 910 on the steel frame and connect the casing 920 reserved on the stone door leaf to form the door shaft. The combination is not tight, there is a large gap, the gap between the door and the stone wall is difficult to effectively control and shift, and it is easy to cause collisions and damage the edges, corners, and edges of the stone veneer, and the shaft mechanism of this sleeve shaft friction when rotating A high coefficient is likely to cause greater wear and tear, which affects the service life of the stone secret door. Moreover, most of the existing stone secret doors and shaft mechanisms are fixedly connected by welding. When the secret door is damaged during long-term use and needs to be replaced, this The fixed and welded structure cannot complete the free disassembly and assembly of the secret door; in addition, the weight of the stone secret door is much heavier than that of ordinary doors, and the existing shaft sleeve bears such a large load that the service life will be greatly reduced
