Abstract
A kind of building door window hole fire prevention node, including the door-window opening surface layer in main structure, the sealant between the sash, hole and the sash that are mounted at hole, the door and window fan being mounted on sash, improvements introduced is: increasing by one layer of foamed ceramic piece fireproof construction layer on door-window opening surface layer.The good effect of the utility model is: by increasing foamed ceramic plate fireproof construction layer in door-window opening inner surface, improve the fire prevention isolation performance of door-window opening node, eliminate the weak link of the inside and outside fire prevention isolation of building, in outdoor generation fire, reduces the harm to indoor occupant, property and reserve the longer departure time.
Description
Technical field
The invention belongs to fixed building fields, and in particular to the fire proof construction of building door window hole.
Background technique
Previous building door window position, the fire prevention just for door and window constantly upgrade and claim, and to the door of building
The fire protecting performance at the position that window hole and door and window are connect with main structure is ignored with structure, only makees ordinary mortar attachment, resistance
It is poor to fire performance, door-window opening connecting portion is made to become fireproof weak link.Master when fire occurs for outside, at door-window opening
Honorable layer is easily damaged by flame, and the buffer action of inside and outside flame, smog is lost, and is caused toxic smog or the tongues of fire to enter the room, is added
Weight fire behavior, expands casualties and property loss caused by fire.
Utility model content
The object of the present invention is to provide a kind of building door window hole prevent fires node, the flame retarding function of lever gear door, window hole,
Overcome aforementioned deficiency existing for existing door-window opening.
Door-window opening node of the invention includes door-window opening surface layer in main structure, the door and window being mounted at hole
Sealant between frame, hole and sash, the door and window fan being mounted on sash, improvements introduced is: in door-window opening table
Layer increases by one layer of foamed ceramic piece fireproof construction layer.
The good effect of the utility model is: by increasing foamed ceramic plate fireproof construction layer in door-window opening inner surface,
The fire prevention isolation performance for improving door-window opening node eliminates the weak link of the inside and outside fire prevention isolation of building, in outdoor hair
When calamity of lighting a fire, reduces the harm to indoor occupant, property and reserve the longer departure time.
Detailed description of the invention
Fig. 1 is door-window opening front elevation in the utility model.
Fig. 2 is door-window opening lateral sectional view in the utility model.
Fig. 3 is foamed ceramic plate sectional view in the utility model.
Specific embodiment
By taking window opening node as an example
Refering to fig. 1, Fig. 2, the window opening node of the utility model include window opening surface layer 2 in main structure 1, peace
The sealant 4 between window frame 3, hole and window frame at hole, the sash 5 being mounted on window frame 3, improvements introduced is:
Increase by one layer of foamed ceramic piece fireproof construction layer 6 on window opening surface layer.
Concrete construction method is:
1, selection tensile strength >=0.25MPa, A1 grades of combustion rating, water absorption rate≤8%, heat storage coefficient >=1.40W(㎡
K), the foamed ceramic plate 6 of density 250-400kg/m3.
2, cement-based polymers rubber cement is modulated.
3, by the bonding portion full coat cement-based polymers mucilage layer 7 of foamed ceramic plate 6 and wall window opening, mucilage layer
Thickness 8-10mm.Foamed ceramic plate 6 is pasted by window size.Paste foamed ceramic plate sequence: a hypostoma-left side (right side) side plate-
Upper oralia-right side (left side) side plate-adjustable module (as shown in Figure 3)
4, window frame 2 being packed into 6 frame of foamed ceramic plate pasted, distance of the window frame 3 away from foamed ceramic plate 6 is 10mm,
Lower mouth needs to adjust distance with 10mm hassock wood.
5, window frame after the installation is completed, filled to form sealant 4 with polyurethane foam by reserving gaps.
6, cement mortar is smeared in foamed ceramic plate surface and sash and foamed ceramic plate filler surface protect surface layer
2.Complete the construction of door-window opening fire prevention node.When insulating layer of external wall is constructed, press box as shown in Figure 2 is needed to construct.
Claims (1)
- The node 1. a kind of building door window hole is prevented fires, including in main structure door-window opening surface layer, be mounted at hole Sealant between sash, hole and sash, the door and window fan being mounted on sash, it is characterized in that: in door-window opening table Layer is lower to increase by one layer of foamed ceramic piece fireproof construction layer.
