Abstract

The invention discloses a manual opening device for a double-layer emergency door, which comprises an inner side hung door (1) and an outer side hung door (2), and a steering synchronous transmission gear system (3) is arranged above the inner side hung door (1) and the outer side hung door (2); connecting pieces (4) and transmission shafts (5) are arranged between the inner side hung door (1) and the steering synchronous transmission gear system (3) and between the outer side hung door (2) and the steering synchronous transmission gear system (3). The vertical hinged door is composed of the outer vertical hinged door, the inner vertical hinged door and the steering synchronous transmission gear system, all the components are machined and produced in a factory, only prefabricated construction needs to be conducted on site, site welding is not needed, and the installation workload is small. Meanwhile, the double-layer emergency door is adopted to replace a traditional single-layer emergency door, the consistency of the external facade effect can be effectively guaranteed, and therefore the problem that the facade impression is affected due to the fact that a traditional emergency door of a full-curtain-wall facade building breaks decorative lines is solved.

Description

Technical field [0001] The present invention relates to an evacuation door for building curtain walls, particularly a two-layer evacuation door manual opening device. Background technique [0002] In the design of the building curtain wall, you need to set the evacuation door in accordance with the specifications; the evacuation door is the room directly to the emission of the walkway, directly open to the door or outdoor door of the evacuation stair. In order to meet the evacuation requirements of personnel, the evacuation door should be opened to the scattered direction. However, for the evacuation door design of the personnel intensive place, the original facial line or curtain wall panel is directly interrupted in the position of the evacuation door. For all-glass curtain walls, this approach can be accepted, but for the facade of the horizontal or vertical decorative line, this practice will cause the line shape to suddenly interrupted, bringing the uncoordinated uncoordinat...
