Building exterior wall heat preserving decorative fire prevention each techonosphere of division board and auxiliary are formed as follows:
Fire lagging (1): adopt coefficient of thermal conductivity less than 0.12W/ (m K), the combustibility grade is the refractory material foamed ceramic heat insulating material of A level, cuts into plate, the minimum 30mm of the thickness of plate, maximum 100mm according to the specification of design.Length and width difference are in ± 3mm, and thickness deviation is in ± 2mm.
Adhesive layer (2): adopt solvent-free epoxy resin based two-component crosslinking curing type adhesive.
Strengthen panel (3): adopt calcium silicate board or cement pressure plare.
Finish coat (4): adopt coating process facings such as fluorine carbon lacquer, fluorine carbon metal paint, stone similar paint.
Fixture (5): adopt the L shaped ironware through preservative treatment, the ironware vertical edge sticks on foamed ceramic warming plate side with epoxy resin based two-component crosslinking curing type bonding adhesive, and the horizontal edge reserving hole is worn anchor bolt and is connected with the basic unit body of wall during installation.
In External Thermal Insulation System, adopt the fire prevention division board that does not fire to be arranged to the fire barrier at a distance from certain altitude, or be arranged to the fire barrier, can effectively stop propagation of flame, reduce fire damage in upper edge, building doors and windows hole along the building level.
Building exterior wall heat preserving decorative fire prevention division board construction techniques is following:
1) according to insulation and decoration fire prevention division board material cutting plan is installed and in external wall basic unit, is reserved the position, bullet level, vertical frame bar.
2) position of fixture (5) anchor bolt, pre-buried anchor bolt (6) expansion tube of holing are confirmed in insulation and decoration fire prevention division board setting-out.
3) adhesive mortar (7) the full coat insulation and decoration fire prevention division board back side, the fire prevention division board is pasted and is gone up wall, twists anchor bolt (6) in advance.
4) tighten anchor bolt (6) after the adhesive mortar drying.
5) fill the level board seam and the vertical plate seam between the division board of preventing fires between common heat insulating decorative board (8) and fire prevention division board with rock wool rod (9), use caulk compound (10) sealing plate seam again.
6) cleaning, maintenance.
The invention has the beneficial effects as follows: building exterior wall heat preserving decorative of the present invention fire prevention division board has advantages such as fire prevention, insulation, durable, shock resistance, good decorating effect; Construction techniques advanced technology of the present invention, economical rationality, easy for installation, the construction energy consumption is low; Meet the national environmental protection requirements of saving energy, can be widely used in the body of wall energy-saving heat preserving engineering of building trade.
