An aluminum alloy fireproof window with built-in opening and closing device and self-locking

Abstract

The invention relates to an aluminum alloy fireproof window provided with a built-in opening and closing device and having a self-locking function. The aluminum alloy fireproof window includes a window sash, a window frame, a window closing device, a connecting rod, a sliding block, a sliding block limiting mechanism and a locking mechanism. The window sash is provided with a frame, the window frame is rotatably connected with one side of the window sash frame, the window closing device is embedded in an upper frame of the window sash, and the connecting rod is connected with the window closing device and the sliding block limiting mechanism. The sliding block and the sliding block limiting mechanism are arranged in a sliding rail disposed in the upper portion of the window frame, and thelocking mechanism is arranged in the frame of the side of the window sash and is in clamped connection with the window frame. The aluminum alloy fireproof window is attractive, does not occupy space,does not affect the installation of a screen window, is not contaminated easily and facilitates cleaning. A limiter has a moderate degree of force on the sliding block, and in the event of a fire, thelimiter can be timely unhooked to release the sliding block. After the locking mechanism closes the window sash, the sealing performance is better, so that expansion air flow in the event of a fire pushes window seams open and causes the fire to leap up, and the safety of the fireproof window is further enhanced.

Description

technical field [0001] The invention relates to the field of fireproof windows, in particular to an aluminum alloy fireproof window with a built-in opening and closing device and self-locking. Background technique [0002] In the GB50016-2014 "Code for Fire Protection Design of Buildings", 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 equipped with openable outer windows; 2. The fire resistance rating of the wall should not be lower than 1.00h, the door of this room should be a Class B fire door, and the fire resistance integrity of the outer window should not be lower than 1.00h; When the external wall insulation system of a building adopts thermal insulation materials with combustion properties of B1 and B2 according to the provisions of Section 6.7 of this code, it shall meet the following requirements: 1 Except for ...

AI Technical Summary

Problems solved by technology

At present, the shutters of the fire-proof windows are mostly exposed, and the stoppers are not unhooked smoothly. After the fire-proof windows are closed in case of fire, the window seams are easily pushed open by the expanding hot air, which poses a safety hazard.
