Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to an invisible door structure for a stone curtain wall and a use method thereof. Background Art

[0002] Building curtain walls are decorative enclosure walls commonly used in modern large and high-rise buildings and are widely used. Curtain walls are an independent and complete overall structural system. Stone curtain walls are widely used because they use natural materials, are bright and crystal, hard and permanent, noble and elegant, have good frost resistance, and have high compressive strength. Sometimes, in order to ensure the uniform and beautiful appearance of the curtain wall, invisible doors need to be opened on the curtain wall to provide passage and fire escape. Stone curtain wall invisible doors are generally required to be consistent with the large surface of the curtain wall in appearance, have uniform gap separation, be easy to open, and be reliable and durable. Since the minimum thickness of the curtain wall stone is required to be more than 25mm, the weight of an invisible door that can meet the minimum fire protection requirements is more than 200kg. The heavy stone can easily cause damage to the pin or hinge, affecting the quality of the invisible door. In addition, due to the heavy weight of the invisible door, the traditional magnetic lock cannot close the door; the pull ring of the traditional heavy invisible door has a poor external appearance and cannot be truly invisible.
