Below in conjunction with each width of cloth figure the present invention is explained further details:
As depicted in figs. 1 and 2, in the middle of two sheet glass 1, through installing ventilation film bag additional, original spatial of similar standard hollow glass structure is divided into three insulated spaces.From a structural point, film bag isolation layer is similar to the intermediate layer glass of the two hollows (the triplex glass unit of two-layer hollow) of standard.But owing to adopt the plastic sheeting edge sealing to form the sealing bag shaped structure, can be used as a new hollow layer that constitutes by film again.With respect to ordinary insulating glass, weight and thickness have been increased to minimum degree.And with respect to three layers of two hollow glass, then be farthest to have reduced weight.
The processing sealing of ventilation film bag can be processed through production line independently in advance.The function of film can be selected according to architect's requirement, like Low-e coating, anti-UV, optics control etc.
With two bidirectional stretching plastic films, according to the corresponding size of glass cut, coincidence, edge sealing.The sealing of film bag is through methods such as welding, bonding agent or heat-sealing limit technology, and the peripheral sealing-in of two films is got up, and forms an airtight bag shaped structure.And ripe industrialization edge sealing technology provides guarantee for reducing difficulty of processing with cutting down finished cost.
Interior hollow isolation layer is to be coincided together by two bidirectional stretching plastic films, along periphery through welding, bonding agent is bonding or method such as heat-sealing limit technology is sealed to form, and is designated hereinafter simply as " hollow membrane ".
See Fig. 3, reach certain intensity and have the limit seam junction of certain width, be called film bag edge sealing 2.1.Stress for fear of place, end angle is concentrated, and carries out the angle of rupture and handles and encapsulate ventilation ozzle 10.2.See Fig. 2, the film bag is hermetically-sealed construction independently, and the confined space that forms in the film bag is interior hollow isolation layer, is called film bag hollow b; The space that film bag and glass form is outer hollow isolation layer, is called glass hollow a.And outer hollow isolation layer tunicle bag is separated into inboard, the two-layer heat insulation hollow in the outside.
See Fig. 5, at specific end angle seam crossing, encapsulation ventilation ozzle 10.2.The ventilation ozzle is the adapter of plastic with certain internal diameter requirement, and the geometry of outer face should be convenient to and the encapsulation of film bag fracture, can adopt heat-sealing or binding agent method for packing.The ventilation ozzle of bottom one side communicates the air pressure of balance glass hollow and film bag hollow with the outer glass hollow of film bag.Top one side ventilation ozzle through be fastened on the structural frames breather valve 10.1 and with the respiratory siphon and the glass outer environmental communication that are embedded in the sealing structure glue-line, the air pressure of the interior exocoel of balance glass.Through the ventilation ozzle in the opposite direction that bottom and top encapsulate respectively, make built-in film bag between in suspension have " buffer air bag " function.
The buffer air bag function of film bag is looked the position of Low-e coating.When there is the Low-e coating on the glass inner side surface, the ventilation ozzle of film bag and the ventilation of glass hollow, the ventilation ozzle communicates with the glass unit external environment condition through respiratory siphon.Be that the glass chamber pressure is when high, through film bag exhaust decompression.Otherwise, then pass through the film bag to the glass hollow inflatable, with the balance that keep-ups pressure.When the diaphragm inboard scribbles the low-e coating, scavenging period and above-mentioned opposite.
The film bag must keep smooth and have certain force of strain in the cavity that two sheet glass form, to guarantee the normal realization of the whole optical function of glass unit.The present invention aids in the acting in conjunction of structural frames again through the built-in tensioning frame of film bag, can realize like a cork thin bag surface tighten, stretch tight flat with stretch tight the jail, thereby overcome the defective of existing mid-mounting thin film technique.For example, utilize the reheat of film heat-shrinkable to handle the membrane technology that stretches tight, utilize the membrane technology that stretches tight of winding spring, all exist, be easy to generate the numerous and diverse contradiction of film and hermetically-sealed construction and processing technology that stretches tight for the line that eliminates stress.
Through the section bar frame of holding the place, angle to be built-in with strainer and hollow membrane bag edge is strutted all around, hereinafter to be referred as " tensioning frame ".Tensioning frame of the present invention can be assembled through production line independently in advance.See Fig. 3, the assembling of tensioning frame mainly is through connecting hornwork 4.3 four frames to be coupled together, and must match with edge sealing size all around.Strainer wherein mainly is that the company's of assurance hornwork drives the outwards mobile expansion of whole tensioning frame along the telescopic displacement that is parallel to the glass surface direction, thereby the film bag is strutted.Simultaneously, form film bag hollow height, and make the surface of two films be in certain surface tension by the decision of tensioning frame thickness.
But a certain amount of desiccant 9 of inner chamber 4.2 fillings of tensioning frame, desiccant adopts the 3A molecular sieve, guarantees that filling gas reaches certain dew point in the film bag.Ventilation ozzle through end angle place is to charging into inert gas in the bag, the drying effect during dew point when guaranteeing first dress and operation are used.
Strutting of film bag mainly by four company's hornworks of holding angles.The junction, angle that connects hornwork is for cooperating the groove and the curved-surface structure of encapsulation ventilation ozzle.With the leakproofness that guarantees edge sealing and avoid the stress line of the film arm of angle that deformational displacement causes.The joint coupling 4.5 that can freely stretch is equipped with at the two ends that connect hornwork respectively, and the built-in flexible member with certain elastic force of joint coupling can be selected spring 4.4 for use.For the ease of with being connected of tensioning frame straightway with fixing, be provided with Embedded reducer union.After film bag edge sealing was accomplished, the compression spring in the joint coupling was in running order, and the middle appropriate location of compression travel.
The elastic force of compression spring in the joint coupling is considered the film bag flat required tensile force that stretches tight on the one hand, also will consider tensioning frame own wt on the other hand.At the glass unit that vertical direction uses, especially should note the influence of the tensioning frame weight of filling desiccant.In like manner, the intensity of film bag edge sealing must be considered the weight of tensioning frame behind the filling desiccant.
Because the film bag press the certain size edge sealing, so the film bag shape finalizes the design almost, and the interior tensioning frame of bag almost is in free expansion state.In order to make the film bag that is installed in the glass chamber after installing additional; Do not bend, distortion such as distortion and keep smooth and certain surface tension, just need the film bag to keep basic shape and offset concentrated ripple or the gauffer that produces because of the film internal stress through uniform deformation.Through with the cooperation of structural frames, the tensioning frame of film bag is suspended is fixed in the cavity of structural frames.Seeing Fig. 1, is basic suspension fixed form shown in the figure, and the barrier film boss 4.1 of tensioning frame closely cooperates with the film flange 3.1 that stretches tight of structural frames.The film flange 3.1 that stretches tight is pressed on the intrados of tensioning frame, and the tensioning frame is produced certain outward thrust, and the film bag is because stretching, and its edge sealing produces inside thrust to the tensioning frame again, and two kinds of active forces reach balance, thereby make film bag surface appear smooth.Among Fig. 4, several kinds of different suspension fixed forms have been showed.

Fig. 4-c is the fixing improvement structure that suspends, and at the arranged outside of the tensioning edge frame film groove that stretches tight, is provided with and stretches tight the adaptive boss of film groove in that the connection parting bead of structural frames is inboard.The outside of tensioning frame is improved to the film groove that stretches tight, and the connection parting bead of structural frames improves tightens boss.Except the film flange of tensioning frame barrier film boss and structural frames closely cooperates, increase the location, the film function of finalizing the design and stretch tight that connect the parting bead boss.In like manner, be pressed in the intrados of tensioning frame under the film flange that stretches tight, the tensioning frame is produced certain outward thrust, and the film bag is owing to connect the stretching of parting bead boss, again the tensioning frame is produced inside thrust and film is further tightened.This mode mainly is the tensioning frame be connected closely cooperating of parting bead, and the film flange that stretches tight is born the effect of the line that eliminates stress more, thereby film bag surface appears smooth.
Fig. 4-d is welded on the plastic film bag edge sealing on the slide block for the fixing practical modified that suspends, and on structural frames, is provided with chute, and slide block is contained in the chute.Film bag edge sealing directly is fixed on the structural frames through the welding slide block.Compare basic mode, the typing of film bag is simpler.The slide block slot of stretch tight the film flange and the structural frames of structural frames has surrounded a tensioning frame chamber with film bag edge; Make the tensioning frame in the chamber along with variations in temperature and deformation and corresponding telescopic displacement is free more; The pulling force that the film that stretches tight is produced is kept evenly constant all the time, the stress line that takes place with counteracting.
Fig. 4-c and Fig. 4-d show the fit structure of two kinds of tensioning frames and structural frames, and every kind of fit structure has all been realized typing, the location of plastic film bag.
To sum up, the inboard of tensioning frame is a barrier film boss 4.1, and it is shaped as rectangular boss, and the width of boss has determined the space size of aerated film bag.The film flange that stretches tight of boss both sides and structural frames forms certain interval, guarantees that boss side surfaces does not contact with pellicular front and film gos deep in the glass cavity open and flatly.
The section bar of tensioning frame 4 is an ellipse, and material selects for use thermal transmittance and coefficient of thermal expansion to be lower than or to be similar to the material of glass.Because the film at the edge sealing and the film flange place of stretching tight closely contacts with tensioning frame table face around the film bag, this contact surface is sphere and smooth, thereby reduces friction the freedom of power to guarantee that film is flexible, avoids the film that stretches tight is produced any damage.
In the inboard of every sheet glass, with the firm section bar frame of structure adhesive tape bonding, be called for short " structural frames " along glass edge.See Fig. 2, it act as and connects two sheet glass and claim as a whole hollow glass, simultaneously, the film bag is suspended be fixed in its inner chamber and it is tightened and smooth.
This section bar frame is two the independent section bars symmetrical each other with respect to two sheet glass, and material selects for use thermal transmittance and coefficient of thermal expansion to be lower than or to be similar to the material of glass.Can connect through connection parting bead 5 and become one.After two structural frames were connected firmly, the tail end of Seal end plate 5.2 and structural frames must be smooth and be same plane, and the frame of the tighter closed loop of 7 formation of the sealant tape on pasting it.
See Fig. 1, this structure adhesive tape 6 has quick sticking effect, and adhesive strength is enough born the structure bonding strength of glass unit, has the mechanical strength of stretch-proof, anti-shearing force.More important role is exactly to guarantee enough to a certain extent little of deformation and the displacement of structural frames.
Structural frames after attaching together, suitable space profiles that can " contain " the tensioning frame of its inner formation.Opposite side with respect to sealed sides is the end plate with decorative effect, is called decorative panel 3.2.Decorative panel has certain angle of slope and matches with the inboard decorative cover of tensioning frame to form and has the whole interior trim face that two diaphragms stretch out the slit.The decorative panel top is the film flange 3.1 that stretches tight, close sheet after, produce in the inboard cambered surface of tensioning frame and to compress the tension force of film downwards, thereby make film tighten and eliminate stress line because of stressed generation.
The outer side edges edge of structural frames is through connecting the parting bead or the two sheet glass volume inside height that directly link together through trip 3.3, and support, and it highly is the whole height of the inner hollow of glass unit, i.e. the entire net thickness of glass unit.The vertical height of structural frames decorative panel has determined the height of the hollow that film and glass form.And two inboard decorative panels of structural frames have constituted the middle break joint outlet that the film bag stretches out.The width of this outlet equates with the vertical height of two decorative panels, makes two films of plastic film bag that the inner space is separated into inside and outside three hollow isolation layers, and the volume of inside and outside hollow isolation layer is impartial.
See among Fig. 4-c that what connect the up-down structure frame is to connect parting bead 5, the adjacent side with the film bag of parting bead is the parting bead boss.This boss embeds in the groove of tensioning frame, and both cooperate, have to the film bag position, styling.Simultaneously, through with the propelling of film bag edge sealing in tensioning frame groove, have and the film bag is carried out secondary tighten function.
Among Fig. 4-d, structural frames directly connects through trip.Wherein the trip end top of a side has and is the fixing draw-in groove of film bag edge sealing.The slide block of compatible good welding material with film is installed in the draw-in groove, is used for the edge sealing of film bag bonding through sweat soldering mode and slide block point type.Through the fixing of welding slide block the film bag is produced certain pulling force.The film bag that the tensioning frame is housed and assembles, and after being fixed in the slide block on the structural frames, film bag surface forms certain surface tension.The inside of film bag struts the film bag through the tensioning frame, simultaneously, again through the pressing down of the film flange that stretches tight, further with the film bag strut stretch tight flat.Finally make the film bag as smooth hollow glass, be suspended in the centre of two sheet glass.
The outer seal structure of glass unit of the present invention is seen Fig. 2, mainly realizes through the two seals structure.The sealing of first road is twined stickup butyl rubber band 7 at the structural frames external surface.The sealing of second road, injecting structure fluid sealant 8 in the space of two sheet glass and 7 formation of butyl rubber band.
