Outward-opening fireproof window locking structure

Abstract

The invention relates to the technical field of doors and windows, in particular to an outward-opening fireproof window locking structure. The outward-opening fireproof window locking structure comprises an aluminum alloy window frame, a conventional locking mechanism 4 is arranged on the fire facing face of the aluminum alloy window frame, a handle and a lock are arranged on the fire backing face, the handle and the lock are connected with an elastic locking mechanism through bolts, the elastic locking mechanism comprises a lock column and an elastic bayonet lock base, one side of the elasticbayonet lock base is clamped and connected to the lock column, and the other side of the elastic bayonet lock base is connected to the aluminum alloy frame through bolts. In order to prevent a steellining from penetrating into aluminum profiles, prevent the aluminum alloy profiles from being corroded and prolong the service life of an outward-opening fireproof window, an elastic lock catch is arranged at the position, corresponding to fire backing face profile of an outward-opening sash, of the frame, the outward-opening sash is provided with the lock column, and the frame is the elastic bayonet lock base; and when a fire disaster happens or fire resistance detection is carried out outdoors, after the fire facing face of the frame and the aluminum profiles of the outward-opening sash aremelted, the locking structure additionally arranged on the fire backing face can connect the frame and the profiles of the outward-opening sash, personal and property safety of the fire backing faceor a successful fire-resistant integrity experiment is ensured.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a locking structure for an outwardly opening fire-resistant window. Background technique [0002] The furnace temperature of the refractory window will rise to 920-940 degrees at the end of the test, and the furnace temperature can rise to 650-680 degrees basically within 5-8 minutes of starting the test, and the melting point of aluminum alloy is about 630 degrees, which means 8 Within minutes, the aluminum profiles close to the fire surface began to melt, and the heat-insulating non-metallic composite material was penetrated into the broken bridge part of the fire surface and the back fire surface, which weakened the heat transfer to the back fire surface and restricted the aluminum profile on the back fire surface. The alloy profile continues to heat up to ensure the supporting effect of the aluminum alloy profile on the back-fired side, but the locking side connecti...

[0002] The furnace temperature of the refractory window will rise to 920-940 degrees at the end of the test, and the furnace temperature can rise to 650-680 degrees basically within 5-8 minutes of starting the test, and the melting point of aluminum alloy is about 630 degrees, which means 8 Within minutes, the aluminum profiles close to the fire surface began to melt, and the heat-insulating non-metallic composite material was penetrated into the broken bridge part of the fire surface and the back fire surface, which weakened the heat transfer to the back fire surface and restricted the aluminum profile on the back fire surface. The alloy profile continues to heat up to ensure the supporting effect of the aluminum alloy profile on the back-fired side, but the locking side connection notches of the existing conventional outward-opening fire-resistant windows are all set on the fire-facing side (outdoor side during normal use);

[0003] In the prior art, a steel lining is penetrated into the aluminum cavity on the fire surface, and the steel lining is connected to the section bar on the back fire surface (indoor side) through the connecting piece for fixing the glass, so as to prevent the steel lining from falling off after the aluminum material on the fire surface melts. , and the hardware of the locking structure is connected to the steel lining to realize the locking structure and ensure the connection between the frame and the opening fan. However, the inserted steel lining and aluminum alloy profiles are two kinds of metals, and There is an electrode potential difference, and aluminum is an easily corroded metal compared to iron, which has a corrosive effect on aluminum alloys, and it is difficult to guarantee the service life of aluminum alloy fire-resistant windows
