Fireproof window with invisible hinge opening mode

Abstract

The invention discloses a fireproof window with an invisible hinge opening mode. The fireproof window comprises a window sash, a window frame and a switch device, wherein the window sash is connectedwith the window frame through hinges; a mounting interval for mounting the hinges is arranged between an outer frame of the window sash and an inner frame of the window frame; and the hinges are arranged at the top and the bottom of the window sash. According to the fireproof window, the hinges are arranged at the top and the bottom of the window sash, the hinges are mounted in the mounting interval between the window sash and the window frame in a hidden mode, the window sash is opened and closed through hinge joint movement of the hinges, connecting arms I, connecting arms II, fixing rods Iand fixing rods II in the hinges form a four-bar mechanism, the fixing rods II are driven to move through movement of the connecting arms I and the connecting arms II, and the fixing rods II are fixedly connected with the window sash relatively, so that the window sash is driven to be opened and closed. When the fireproof window is in a closed state, the hinges are folded into the mounting interval, the window sash is separated from the external space through fireproof rubber strips and fireproof glass, and good air tightness and fireproof performance are achieved.

Description

technical field [0001] The invention belongs to the technical field of fireproof windows, and in particular relates to a fireproof window with an invisible hinge opening method. Background technique [0002] A fire-resistant window refers to a window that, together with the frame, can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. Fire windows should be used when lighting and ventilation are required on the outer walls of two buildings with insufficient fire separation distance, or between spaces separated by firewalls. [0003] The sash of a traditional fireproof window is generally connected to the window frame by means of exposed hinges. The fireproof window with this structure is prone to rust, deformation, cracking and other defects at the welded part of the hinge, which affects the overall performance and appearance of the fireproof window. . [0004] my country began to implement the new building fire ...

Problems solved by technology

[0008] In view of the new reform of the requirements of the new building fire protection codes on fire windows, most of the traditional fire windows cannot meet the requirements of the new building fire codes in terms of air tightness, durability and fire performance, so it is necessary to develop a new fire window
