Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a fireproof door and window which is easy to disassemble and maintain. Background Art

[0002] Fireproof windows refer to windows that, together with their frames, can meet the requirements of fire resistance stability and fire resistance integrity within a certain period of time. Fireproof windows should be used when lighting and ventilation are required on the exterior walls of two buildings with insufficient fire separation, or between spaces separated by fire walls. With the continuous development of urbanization, prefabricated houses are widely used as an environmentally friendly and economical house in various construction sites as work sheds and warehouses. In the existing technology, flame-retardant and fireproof prefabricated houses generally need to be installed with fireproof windows.

[0003] Since prefabricated houses mainly use sandwich panels as wall enclosure materials, before installing the fireproof windows, it is necessary to use color steel sheets to encapsulate, anchor and level the sandwich panels around the installation location, and then use expansion screws to fix the fireproof windows. However, the installation efficiency of fireproof windows in this way is relatively low, and it is very inconvenient to recycle and reuse them later, or to repair and replace them.
