CN2097891U - Steel and wood compound double-layer glass insulating window - Google Patents

Abstract

The utility model relates to a composite steel-wood double-layer glass insulating window, comprising a window frame, a sash and double-layer glass. The window frame and the sash are formed by the composite of hollow steel and timber with a T-shaped cross section, the limiting surface of the utility model is cemented by adhesive and is fastened by a long wood screw, and the double-layer flat plate glass is cemented on a wooden sash bar forming hollow glass with an air layer. The heat transfer coefficient of the utility model can be reduced to about 2.8w/m+[2]k, and the utility model can save 56% of energy than the ordinary steel window, 30% of energy than the single frame double-layer glass thermal insulation steel window and 10% of energy than the steel molding composite thermal insulation window. The utility model has the advantages of light weight, labour saving of installation, time saving, convenient opening and low cost.

Description

Steel and wood compound double-layer glass insulating window

The utility model belongs to a kind of building doors and windows.

The ratio that window heating heat waste outside the building accounts in the space enclosing structure heat waste is very big, and about 50%.The heat-insulating property that improves window is the important channel of reducing the architecture enclosing structural heat loss.Existing window have timber window, plastic window, steel sash, steel-plastics composite window several, timber window is because China's timber resources poorness, and limited its development; Though and the plastic window good heat insulating, cost is higher, also can not large tracts of land be generalized on the residential building; At present, steel sash has been used in northern heating area in a large number in residential building and the public building, and wherein continuous its heat-insulating property of hot steel sash is very poor, and (thermal transmittance is 6.4W/m ²K), even make the two glass steel sashes of single frame (window frame is warm constantly), thermal transmittance also can only drop to 4.0W/m ²About k.Improve the heat-insulating property of steel sash, the one, window frame is disconnected warm, but has increased the complexity of technology, and cost rises more, and the 2nd, adopt the good material of steel and heat-insulating property compound.

The purpose of this utility model provides the compound two glass heat insulation windows of a kind of steel wood, makes it both have advantages of high strength, has the advantage of good heat insulating again.

Steel of the present utility model wood Composite Double glass heat insulation window is made up of window frame, sash, glass, it is characterized in that: window frame and sash are that hollow profile steel and section are that the wood composite of T shape forms, its interface adhesive cementation, and fastening with long wood screw; Two-layer sheet glass gluing has the hollow glass of air layer in the middle of becoming on wooden moulding.

Adhesive material is latex or marine glue.

The utility model has the advantages that:

Good heat insulating, energy-saving effect is remarkable.The thermal transmittance of this window can drop to 2.8W/m ²About K, even it is lower, more energy-conservation 56% than common steel sash, more energy-conservation 30% than single frame and double glasses insulation steel sash, mould composite insulating window energy-conservation 10% than steel, because this window good heat insulating, can be widely applied to north cold area and severe cold area, solve effectively, cause the out layer window inner surface serious frosting problem to occur because the Steel window with double layer sealing is bad, improve the light transmittance of glass, improved window daylighting in winter effect.

Material source is wide, during making, and the special-less process requirement, combination process is simple, and cost is lower.

In light weight, install save time, laborsaving, it is convenient to open.

Below in conjunction with drawings and Examples the utility model is described in detail:

Fig. 1 is the elevation of the utility model steel wood Composite Double glass heat insulation window.

Fig. 2 is the schematic diagram of Figure 1A-A section.

Embodiment: steel wood Composite Double glass heat insulation window, to form by window frame 1, sash 2, double-layer glass 3, window frame and sash are that hollow profile steel 4 and section are that the timber 5 of T shape is composited, its interface usefulness cementing agent 6 gluings, and fastening with long wood screw 7; Two-layer sheet glass gluing has the hollow glass of 10～20 millimeters air layers in the middle of becoming on wooden moulding 8.Hollow profile steel can be 25A structural section commonly used, the connection joggle between the timber, the inner latex of using in timber and hollow profile steel junction, periphery marine glue (silica gel).The thickness of window-glass is 3mm, and the wooden frame bar that exposes of false hollow glass is brushed damp-proof paint, prevents that steam from entering glass sandwich.The fixing of glass and window frame, sash gets final product with putty 9 or timber bead 10.Seal with weather strip 11 between window frame and the sash.

Claims (2)

1, a kind of steel wood Composite Double glass heat insulation window is made up of window frame, sash, glass, it is characterized in that: window frame and sash are that hollow profile steel and section are that the wood composite of T shape forms, its interface adhesive cementation, and fastening with long wood screw; Two-layer sheet glass gluing has the hollow glass of air layer in the middle of becoming on wooden moulding.

2, according to the steel wood Composite Double glass heat insulation window of claim 1, it is characterized in that: described adhesive material is latex or marine glue.
