Abstract
This invention relates to double glazing having two glass sheets with numerous spacers arranged therebetween, a void therebetween being sealed in a decompressed condition. Conventionally, the glass sheets have edges thereof spaced from each other by a seal. Under the influence of the binding force of the seal atmospheric pressure tends to act less on outermost spacers than on the other spacers. Consequently, the outermost spacers tend to move between the glass sheets. According to this invention, an outer interval (L1) between each outermost row of spacers (2) and a seal (4) is set at least equal to a basic interval (L0) between the outermost row and a second row adjacent thereto. Consequently, the spacers in the outermost rows bear a larger share of atmospheric pressure acting on the sheet surfaces than the spacers in the other rows. A sufficient force is secured to hold the spacers in the outermost rows in place, thereby preventing the spacers in the outermost rows from moving between the two glass sheets.
Description
Technical field
The present invention relates to double-glazing unit, wherein two blocks of glass has by predetermined space along glass pane surface and in many first gap keepers of in a row arranging between them, and is located at the second hole keeper that is used to be sealed in the space under decompression state between described sheet glass between the whole outward flange of these two sheet glass.
Background technology
In general, can be that isolator structure (wall and roof) provides heat insulation with lagging material.But the picture door has the spacing body in aperture then must be convenient to open and close and the transparency need be arranged with window and so on.Therefore be difficult to lagging material is used on the entire area of this class spacing body.Always be short of aspect heat insulation in this class aperture that does not add lagging material above.Double-glazing unit has been conceived to be used for above-mentioned aperture, and it comprises that two agllutinations are incorporated into glass together, and intermediate formation one layer of air plays a part thermal insulation layer.
One of shortcoming of this double-glazing unit is that sheet glass itself is thicker, adds sash, often is tasteless outward appearance.The double-glazing unit of thin height insulation had been proposed for this reason, be distributed with numerous partition member (be equivalent to the aforesaid first gap keeper and get the paxillae form that does not hinder the transparency) between two blocks of glass wherein, between the whole edge of these two sheet glass, then be provided with the second gap keeper, between two blocks of glass, to form the space of decompression.
Owing to disposed the above-mentioned partition member and the second gap keeper, even the decompression of the space between two sheet glass also can keep the space be scheduled to betwixt.Referring to Fig. 4 this class double-glazing unit is described below.Partition member 10 is provided with every (below be called basic interval) 11 by the basic compartment of determining according to the intensity of sheet glass 1.Interval between the outermost partition member 10a and the second gap keeper 12 (being called outer rim later at interval) calculates mark usually and determines, and will consider the width (or length) of sheet glass in the scope that is no more than basic interval 11.This is because the size of sheet glass may not be the integral multiple of above-mentioned basic interval usually.
The edge of two sheet glass is then by the second gap keeper constraint.But among above-mentioned double-glazing unit, outer rim is at interval 13 less than basic interval 11, under the influence of the restraint force of the second gap keeper 12, barometric point to outer most edge at interval the effect of 10a always less than to other effect at interval.Therefore, sheet glass will make the confining force that is delivered on the partition member insufficient, so that partition member easily moves between sheet glass.If partition member moves between sheet glass, the layout of whole separator structures will be unbalanced and damage its outward appearance.In addition, can increase the variation of sheet glass strained condition and weaken its intensity.
For this reason, purpose of the present invention promptly is to provide the double-glazing unit that can overcome above-mentioned shortcoming and suppress the first gap keeper motion.
Summary of the invention
Above-mentioned purpose is realized by the summary of the invention of claims defined.
The invention provides by predetermined space in many first gap keepers of in a row arranging along its surface between two sheet glass be located at the second gap keeper between these two whole outward flanges of sheet glass, and it is characterized in that, each of this first gap keeper efflux most and the second gap keeper between outer rim set at interval and equal each at least and efflux most and adjacent with it second row's basic interval.
According to said structure, equal basic interval at least because outer rim set at interval, the first gap keeper in effluxing is most compared with the first gap keeper among other row, will bear the barometric point on the glass pane surface of acting on than large portion.This part barometric point that is increased just can compensate and run in the prior art because the restraint force on the sheet glass of affacting of the second gap keeper is arranged, and cause efflux most in the confining force of the first gap keeper insufficient.The result can make the confining force that affacts on all first gap keepers substantially the same, thereby can prevent that the first gap keeper that effluxes most from moving between two sheet glass.Double-glazing unit of the present invention has been arranged, just can avoid now making the layout of the first gap keeper to become unbalanced and deface, and can avoid owing to first motion of gap keeper between two sheet glass weakens intensity.
In addition, the second gap keeper has also increased the restraint force to sheet glass, thereby has further improved sealing property.
Preferably outer rim is set at interval and is twice in basic interval.
Particularly it is desirable to, make outer rim be set at 1.25 times to 2 times of basic interval at interval.
Adopt the said structure decapacitation to avoid the first gap keeper to become unstable, can also prevent glass sheet breakage easily as outside above-mentioned the moving.Surpass basic interval greatly if outer rim is crossed at interval,, will strengthen the tension stress of glass surface and make glass sheet breakage then along with strengthening the effect of contraction of the second gap keeper to sheet glass.
In other words, because outer rim has minimum value 1 with respect to the multiple of basic interval at interval, just can avoid the first gap keeper motion.And, avoided glass sheet breakage because this multiple has the surperficial tension stress by in the marginarium of the second gap keeper constraint of maximum value 2, two sheet glass and just can be controlled in the allowable stress level of sheet glass.
Advantage of the present invention is set out in other dependent claims.

Implement optimised form of the present invention
Referring to accompanying drawing in detail form of implementation of the present invention is described in detail below.
Fig. 1 and 2 illustrations double-glazing unit of the present invention.Double-glazing unit P comprises a pair of sheet glass 1, between two glass pane surface along this surface by being interval with many partition members (they are examples of the first gap keeper), so that the space V of decompression to be provided between this sheet glass 1A and 1B.
It is outstanding on the direction that is parallel to the plate face that the outward flange of two sheet glass 1 is configured to a sheet glass 1A who makes wherein.The edge of space V is by the effective and sealing reliably of a kind of sealing material do of deposition on protuberance 5 when forming sealing member 5.
As for the layout of numerous partition members 2, be to make each partition member 2 that effluxes most and the outer rim between the sealing member 5 basic interval L1 between L1 〉=each each second row's partition member 2 that effluxes most and be adjacent at interval.
In this form of implementation, the about 20mm of basic interval L0; Outer rim is the about 20～40mm of L1 at interval, promptly is issued in its maximum situation and is twice in basic interval L0.
When outer rim at interval L1 set when equating with basic interval L0, i.e. L1=20mm then acts on the stress (confining force) that effluxes most on the partition member 2a and acts on second and arrange equating on the partition member 2b.So just avoided the partition member 2a that particularly effluxes most may be easy to move.Confirmed already, when outer rim when at interval L1 is less than basic interval L0, the share that affacts the barometric point on the glass pane surface that the partition member 2a that effluxes is most born is just less, and owing to the restraint force that has sealing member 5 to act on the double-glazing unit makes the stress (coercive force) that affacts on the partition member 2a less, so the partition member 2a in effluxing most is convenient to move (seeing Table 1).
The experiment situation that table 1 is listed is that partition member is arranged to: L0 is set at 20mm and makes L1 by being set in every 5mm in 10～40mm scope at interval, and moving of partition member 2a counted during statistics effluxed most then.Experimental result shows, when L1 was set to 10mm and 15mm, ading up in effluxing most had 51 and 12 respectively in 60 partition members and move, and this has just become problem in actual applications.And get when being decided to be 20～40mm the motion of partition member in just having prevented from basically to efflux most as L1.Especially preferably L1 is set at 25～40mm.That is to say that L1 should be set at 1.25～2 times of L0.Under such setting, the motion of partition member can not damage outward appearance in just preventing from reliably to efflux most, makes the variation minimum of the force-bearing situation of sheet glass, and can produce unblemished double-glazing unit aspect intensity.

Verified, L1 is set at 2 times when basic interval L0 is L1=40mm when the outer rim interval, is reached by the surperficial tension stress in two glass plate edge districts of sealing member 5 constraints to approximate the long-term tension stress value that allows of sheet glass.Like this, when at interval L1 is set in 2 times of basic interval L0 outer rim, just the internal stress of sheet glass can be restricted in the tension stress scope of permission, so break with regard to having avoided sheet glass to reduce pressure to cause because of space V seals.
Fig. 3 shows and bright above-mentioned double-glazing unit P experimentized, and measures the result that outer rim concerns between the surperficial tension stress in the marginarium that retrained by sealing member 5 of L1 and two sheet glass at interval.
In this experiment, two sheet glass by surperficial tension stress in the marginarium of sealing member 5 constraint, intermarginal outside every L1 by measuring from six kinds of situations that 28mm increases to 53mm every 5mm.
Experimental result shows that above-mentioned surperficial tension stress increases with the increasing of outer rim interval L1.When L1=40mm (be equivalent to L0 long at interval 2 times), this surperficial tension stress reaches 100kg/cm
2, and this is 3mm thick float glass plate allows the tension stress value for a long time.
