Problems solved by technology

[0002] In the past, the position of doors and windows of buildings only raised requirements for the continuous upgrading of the fire protection of doors and windows, while ignoring the fire performance and structure of the openings of doors and windows of buildings and the parts where doors and windows are connected to the main structure. Poor, making the connection of door and window openings a weak link in fire protection
In the event of an external fire, the main surface of the door and window openings is easily damaged by the flame, losing the isolation effect of internal and external flames and smoke, causing toxic smoke or flames to enter the room, aggravating the fire, and expanding the casualties and property losses caused by the fire

Embodiment Construction

[0017] Take the window opening node as an example

[0018] refer to figure 1 , figure 2 , the window opening node of the present invention comprises the window opening surface layer 2 on the main structure 1, the window frame 3 installed at the opening, the sealing layer 4 between the opening and the window frame, the window sash 5 installed on the window frame 3, made The improvement is: adding a layer of foamed ceramic sheet refractory structure layer 6 on the surface layer of the window hole.

[0019] The specific construction method is:

[0020] 1. Choose foamed ceramic plates with tensile strength ≥ 0.25MPa, combustion grade A1, water absorption ≤ 8%, heat storage coefficient ≥ 1.40W (㎡·k), and density 250-400kg / m³.

[0021] 2. Prepare cement-based polymer mortar.

[0022] 3. The adhesive part of the foamed ceramic plate 5 and the window opening of the wall is covered with a cement-based polymer glue layer 6, and the thickness of the glue layer is 8-10mm. Paste the ...

Abstract

The invention relates to a fireproof node for a building door or window opening and a construction method. The node includes a door or window opening surface layer on the main structure, a door or window frame installed at the opening, a sealing layer between the opening and the door or window frame, and a door or window sash arranged on the door or window frame. The improvement is: a layer of foamed ceramic sheet refractory structure layer is added on the surface layer of the door or window opening. The construction method comprises the following steps of: coating cement-based polymer rubbercement at the opening of the door or window, sticking a foamed ceramic plate door or window frame into a stacked and foamed ceramic plate frame, filling the reserved gap with polyurethane foam, coating cement mortar protection surface layer. By increasing the foaming ceramic plate fireproof structure layer on the inner surface of the door or window opening, the fireproof and isolation performancesof the door or window opening node is improved, the weak link of the inner and outer fireproof and isolation of the building is eliminated. When fire happens outdoors, the danger to indoor personneland properties is reduced and longer evacuation time is left.

Description

technical field [0001] The invention belongs to the field of fixed buildings, and in particular relates to the fireproof structure of the door and window openings of buildings and the construction of the fireproof structure. Background technique [0002] In the past, the location of doors and windows of buildings only raised requirements for the continuous upgrading of the fire protection of doors and windows, while ignoring the fire performance and structure of the openings of doors and windows of buildings and the parts where doors and windows are connected to the main structure. Poor, making the connection of door and window openings a weak link in fire protection. In the event of an external fire, the main surface of the door and window openings is easily damaged by the flame, losing the isolation effect of internal and external flames and smoke, causing toxic smoke or flames to enter the room, aggravating the fire, and expanding the casualties and property losses caused...
