Abstract
The utility model provides a fireproofing and heat insulating curtain wall, which comprises a veneer 1, keels 2 (comprising upright columns 21 and cross beams 22) and an insulation layer 3, the veneer 1 is fixed at the outer sides of the keels 2, the insulation layer 3 is filled between the keels 2, and the curtain wall is characterized in that: fireproofing strips 4 are filled at sides of the keels 2, and a fireproofing surface layer 5 is arranged on the surface of the insulation layer 3; the interaction between the fireproofing strips 4 and the fireproofing surface layer 5 can enhance the resistance to primary fire, delay the ignition time, and hinder the fire spreading and aggravation. The utility model has the advantages that: the insulating property is optimal, and the coefficient of thermal conductivity is one second that of a polystyrene board (EPS) and one third that of rock wool under the same insulating condition; and the insulation layer has no gap and empty cavity, and has excellent sealing and waterproofing property as well as strong resistance to primary fire, and the curtain wall can put off the ignition time and hinder the fire spreading and aggravation.
Description
Technical field
The utility model relates to the decorative curtain wall of office premises.
Background technology
Utilities building adopts curtain wall decoration more, the in the past many employing rock wools of its insulation, and now because of energy conservation standard improves, the insulation stickup polyphenyl bubbles that adopt are moulded plate (EPS, XPS) more.These two kinds of heat insulating materials cut both ways, and the rock wool fireproof performance is good but suction causes insulation failure too by force.The plate heat-insulating property is good though the polyphenyl bubble is moulded, and fire line is poor, and one meets fire, and the short time intensity of a fire causes personnel, property loss to increase with a loud crash.And both are because of being that cavity structure and the slit with the body of wall basal plane all appears in block construction, and the convection current of air in outside air layer and the cavity is caused in its slit, quicken interchange of heat cause energy a large amount of run off and during fire oxygen pour in, discharge fume rapidly and cause with a loud crash.Insulation layer and keel slit are difficult for sealing, except that heat runs off, also cause moisture to Corrosion of Metallic Materials and heat insulating material internal condensation, go mouldy.
Summary of the invention
The purpose of this utility model is to provide a kind of building curtain wall that hinders fire spreading and polyurethane thermal insulation system with a loud crash.
The utility model provides a kind of fireproof heat insulating curtain wall, comprise facing plate, keel (comprising column and crossbeam) and insulation layer, the facing plate is fixed on the outside of keel, and insulation layer is filled between keel, it is characterized in that: the keel inboard is filled with fireproof strip, and insulation layer surface has the fire prevention surface layer; Fireproof strip adds that the acting in conjunction of fire prevention surface layer to strengthen the drag to elementary fire, delays the time on fire, hinders fire spreading and reaches with a loud crash.
The fireproof heat insulating curtain wall that the utility model provides, its insulation layer can be polyurethane foam plactics (PUF) or spraying modified polyurethane (PIR) insulation layer, the heat-insulating property of polyurethane foam plactics (PUF) and modified polyurethane (PIR) is the most excellent, its coefficient of thermal conductivity is 1/2 of a polyphenyl plate (EPS, XPS) under equal heat-retaining condition, 1/3 of rock wool, thus curtain wall thickness can be reduced.
The fireproof heat insulating curtain wall that the utility model provides, its fire prevention surface layer can be dry-type or rubber cement type polymer fire prevention rubber cement class, water-based or oiliness fireproof paint class, the perhaps light bone fire-proof cement of EPS, PUF, glass microballoon or perlite rubber cement class fire prevention mask, to strengthen drag to elementary fire, delay the time on fire, hinder fire spreading and reach with a loud crash.
The fireproof heat insulating curtain wall that the utility model provides, its fireproof strip can only be filled in keel 2 inboards that part constitutes grid, and insulation layer 3 strict encirclement seal.
The fireproof heat insulating curtain wall that the utility model provides, its fireproof strip can be for: rock wool, with or without the glass mat or the silicates inorganic heat insulation material of aluminium foil.
The fireproof heat insulating curtain wall that the utility model provides, its facing plate are stone material and sheet metal (aluminium-plastic panel) or glass, to increase attractive in appearance and light transmittance.
The fireproof heat insulating curtain wall that the utility model provides, its advantage is: heat-insulating property is the most excellent, and its coefficient of thermal conductivity is 1/2 of a polyphenyl plate (EPS) under equal heat-retaining condition, 1/3 of rock wool; Insulation layer is seamless, no cavity, and sealing, water resistance is superior, and is strong to the resistance of elementary fire, can delay the time on fire, hinders fire spreading and with a loud crash.
Description of drawings
Fig. 1 is the structural representation of fireproof heat insulating curtain wall.
The specific embodiment
The fireproof heat insulating curtain wall, its structure as shown in Figure 1, comprise facing plate 1, keel 2 (comprising column 21 and crossbeam 22), insulation layer 3 and fireproof strip 4, facing plate 1 is fixed on the outside of keel 2, insulation layer 3 is filled in 2 of keel, keel 2 inboards are filled with fireproof strip 4, and whole baffle wall is fixed on the built-in fitting 7 of exterior wall 6.
