Description

The hollow glass assembly

The utility model relates to the assembly that is used to assemble hollow glass.

For a long time, hollow glass adopts the Aluminum Hollow spacer bar to separate glass, fills with poly-sulphur glue at bar body periphery to seal, and is desiccant-filled in the aluminium extruded sections, by the moisture in the perforate heat absorbing glass interlayer on section bar surface.Because the heat-proof quality of aluminium matter parting bead is poor, the thermal transmittance height, when moisture was met in the desiccant assembling back of packing in the bar body, desiccant moisture absorption heat release easily reacted with the aluminium spacer bar, so the aluminium spacer bar is not corrosion-resistant, application life weak point; In installation process, the aluminium spacer bar is more sliding in addition, must use glass clamp or be fixed on glassly with other pressure, has brought many inconvenience to assembling so again.

In order to solve corrosion-resistant and problem thermal insulation, adopted the plastics profiled spacer of polyvinyl chloride etc. to replace aluminium matter profiled spacer in the hollow glass assembly, a kind of plastics composite member that is used to assemble double glazed unit is disclosed as CN2117451U, it by soft, hard PVC composite co-extruding go out the spacer bar that processing and forming makes, the dovetail fastening limit and the plastics socket joint angle of hard PVC extrusion molding formed.But this hollow glass load module complex structure is difficult for processing, and inconvenience is installed.

A kind of insulation glazing assembly is disclosed among the CN1271401A, between two parallel glassy layers, be provided with the plastics profiled spacer, this profiled spacer includes the bar body of hollow, inside is filled with desiccant, on the face of glass sandwich inboard, have pore, be filled with fluid sealants such as poly-sulphur glue between section bar lateral surface and two glassy layers, the cementitious materials of field-applied when being assembling on the two sides of this profiled spacer.The shortcoming of this profiled spacer is that some plastic material fire resistance is bad; In addition, when assembling, need carry out on-the-spot gluing in the profiled spacer both sides; And because plastic material does not particularly have bonding force between polychloroethylene section bar and the poly-sulphur glue, so overall performance and sealing performance ideal not really all.

The technical problems to be solved in the utility model is, overcomes above deficiency of the prior art, provides a kind of corrosion-resistant, fire-retardant and heat-proof quality is good, good sealing effect during assembling, a kind of hollow glass load module that globality is strong, be convenient to install.

For achieving the above object, the utility model provides a kind of hollow glass assembly, comprise parallel first glassy layer (7) and second glassy layer (8), be provided with the polyvinyl chloride spacer bar between two glassy layers, this spacer bar comprises the bar body (1) of hollow, and inside is filled with desiccant (6), has pore (2) on the surface of glass sandwich inboard, with poly-sulphur glue (5) sealing, it is characterized in that between bar body (1) outside and two glassy layers:

(A) two sides of the bar body (1) of this spacer bar are provided with pressure-sensitive adhesive layer (3),

(B) the bar body (1) of this spacer bar on the surface in the glass sandwich outside, scribble one deck adhesive glue (4), to improve the bonding force between this body (1) surface and the poly-sulphur glue (5).

The bar body of the spacer bar in the glass assembly of the present utility model adopts the extrusion molding of Corvic raw material, overcome the shortcoming that existing aluminium matter spacer bar is not corrosion-resistant, heat-proof quality is bad, have excellent heat insulation property, its thermal transmittance is very little, only is 1/1250 of aluminium matter spacer bar; Do not react with desiccant, corrosion-resistant, long service life; The energy consumption of production unit weight is 1/8.8 of an aluminium parting bead, and cost is low; And compare with other plastics profiled spacer and to have good flame retardancy.

The utility model has no particular limits the shape of cross section of the bar body of the spacer bar in the glass assembly, can be rectangle or polygon, also can be various profile shapess, as long as this section bar can be realized technique effect of the present utility model.Air inlet on the bar body can have any shape, and is square as the pin hole shape, triangle, bar shaped or the like.

In the glass assembly of the present utility model, the bar body two sides of hollow glass spacer bar are provided with pressure-sensitive adhesive layer.Pressure sensitive adhesive is commonly called as adhesive sticker, can avoid the sideslip of glass in the assembling process or the inconvenience of on-the-spot gluing, and together plays the effect of double seal with poly-sulphur glue.For the ease of transporting and preserving, before assembling, outside pressure-sensitive adhesive layer, be attached with strippable coverlay.

In the technical solution of the utility model, on the another side except that two sides on the bar body, be coated with one deck adhesive glue, polyvinyl chloride bar body and poly-sulphur glue bond together by adhesive glue when assembling, overcome the shortcoming of no bonding force between the poly-sulphur glue of polychloroethylene section bar and sealing usefulness, improved overall performance.This adhesive glue can be any glue that can make contact surface produce bonding force, and the utility model is preferably PVC glue.

Fig. 1 is the utility model hollow glass component assembling sectional schematic diagram.

For the structure to hollow glass load module of the present utility model has further understanding, details are as follows in conjunction with embodiment of the present utility model:

With reference to accompanying drawing, in Fig. 1, the hollow glass assembly comprises the first parallel glassy layer 7 and second glassy layer 8, the polyvinyl chloride spacer bar is between layer glass layer 8 and 9, be provided with pressure-sensitive adhesive layer 3 (coverlay of outside is peeled off) with glassy layer 8 and 9 side surfaces contacted, the bar body 1 of spacer bar has air inlet 2 on the one side of glass sandwich inboard, inside is filled with desiccant 6, on the face in the glass sandwich outside, scribble G06-M0761 PVC glue 4 at bar body 1, on this surface, seal with poly-sulphur glue 5.
