Outward-opening type fire resisting window

Abstract

The invention discloses an outward-opening type fire resisting window. The outward-opening type fire resisting window comprises a fixing frame and a turning frame, wherein the turning frame is connected in an outward turning mode relative to the fixing frame, and a spring hinge driving the turning frame to close is arranged between the fixing frame and the turning frame; a locking body is arranged at the bottom of the turning frame; a handle and a locking rod are arranged on the turning frame, and the locking rod is driven by the handle to rotate; the locking body comprises a locking case, a rotating piece, a pushing piece and a locking tongue, wherein the rotating piece is driven by the locking rod to rotate; the pushing piece abuts against a clutch of the rotating piece; the locking tongue is connected with the locking case in a slipping mode; the indoor-toward side face of the locking tongue is outdoors inclined ; and a first locking base is arranged on the fixing frame and is used for inserting of the movably locking tongue. When the turning frame is closed relative to the fixing frame, the locking tongue is drawn into the locking case, and the locking tongue is inserted into the first locking base through a first elastic piece, so that automatic locking is achieved.

Description

technical field [0001] The invention relates to the field of fireproof windows, in particular to an outwardly opening fireproof window. Background technique [0002] According to 5.5.32 of the GB50016-2014 "Code for Fire Protection Design of Buildings" implemented on May 1, 2015, for residential buildings with a building height greater than 54m, each household should have a room that meets the following requirements: 1. It should be installed against the outer wall, and should be 2. The fire resistance rating of the inner and outer walls should not be lower than 1.00h. The door of the room should be a Class B fire door, and the outer window should be a fireproof window with a fire integrity of not less than 1.00h. That is to say, in high-rise residential buildings, each household in a building with more than 18 floors needs to design a refuge room. In order to meet the needs, the refuge room must be installed with Class B fireproof windows. Increased fire integrity requirem...
