[0050] The labor cost for installing the hidden door of the present invention is as follows:

[0051] 1 installer: labor cost is 300 yuan

[0052] The working process of the present invention is as follows:

[0053] According to the characteristics of the pipe shaft fire door 2, the characteristics of its door shaft (hinge 5) are fully utilized, the basic framework of the wall surface material is reduced to form an integral body, and the opening angle of the door leaf and the opening gap are increased by the opening angle of the concealed hinge 5. While meeting the design effect, the conventional process is reduced in deformation, construction steps, inconvenience, and other problems. The present invention has the following characteristics:

[0054] 1. By changing the installation position of the pipe shaft fire door 2, the opening angle of the hinge 5 and lengthening the lock core and other technical requirements, the door panel is used as the basis of the surface material for installation.

[0055] 2. Calculate the finished surface according to the thickness of the surface material and the installation method, conduct secondary layout according to the on-site civil engineering structure, confirm the wall layout and joints in advance, and comprehensively consider the technical specifications such as the ceiling points to ensure that there is no impact from factors such as equipment after the door leaf is opened, ensure the opening angle of the fire door, and meet the fire inspection and acceptance requirements.

[0056] 3. Calculate the weight of the surface material and the door leaf in advance, and select the appropriate hinge 5 based on the overall total amount. The hinge 5 load-bearing capacity redundancy should be more than 20% to ensure that the hinge 5 has no load-bearing problems after installation, the concealed door opens smoothly, and the door leaf joints are flat without height differences. The door leaf hinge 5 will not sag, deform, twist, or have problems such as large and small heads after being stressed due to the addition of the surface material.

[0057] 4. Traditional hidden doors are closed by means of beads or magnetic contacts, which may cause problems such as poor opening, insufficient magnetic force or damaged beads, which may lead to failure to open. The installation position of the beads or magnetic contacts may be easily warped or deformed due to stress. The on-site method is to change the length of the lock core, directly open a hole on the surface material, and process it through the lock cover or flange edge. Later, it can be opened directly with a key, which is convenient for opening and maintenance, and can meet the design effect and provide convenience for later maintenance.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
