Abstract

The invention provides an installation method of a fire box stone blank door. The installation method is used for a fire box blank door shaft device which can be opened easily, effectively and conveniently. When the first section is opened, a first rotary sleeve column is rotated inside a first sleeve, a second rotary sleeve column is sleeved with a second sleeve for rotation, the enough large distance is kept between a fire box stone blank door body and a decoration face on the side face of the fire box stone blank door when the fire box stone blank door is opened, meanwhile, a first rotary shaft and a second rotary shaft can be overlapped when the fire box stone blank door is closed, only a small space is occupied, and the method is applicable to the condition that the distance between the decoration face on the side face of the fire box stone blank door and a wall structure is small. In addition, when the second section is opened, a third rotary sleeve column is rotated in a third sleeve, and the fire box stone blank door can be rotated by at least 180 degrees.

Description

technical field [0001] The invention relates to a method for installing a stone hidden door of a fire box. Background technique [0002] As a guarantee of fire safety, the fire box is essential in architectural decoration design. The traditional fire box door conflicts with the integrity of the stone wall, destroying the aesthetics. The fire box secret door with stone as decorative surface has been widely used. [0003] For construction conditions where the distance between the decorative surface and the structure is small, the traditional "vertical pin shaft" device is difficult to open to 90 degrees. Even on the basis of chiseling the wall, it can only be opened to about 90 degrees, which does not meet the current specifications. Among them, Section 5.13.3 of the specification GB14561-2003 requires that the opening of the fire hydrant box door should not be less than 160°. [0004] like figure 1 As shown, the traditional vertical bolt shaft opening device, in the case ...
