Among the figure, 1 is sash, and 2 is window frame, and 3,7,12,13 is sealing joint strip, and 4,9,10 are the edge of dripping, and 5 is rain cape, and 6,11 are prominent edge, and 8 is glass block.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
As seen in Figure 1, the inward opening plastic window of this programme has sash 1 and window frame 2.In sash 1 arranged outside rain cape 5 is arranged, sash 1 is closed the back arranged outside the slit, is provided with sealing joint strip 3 in the chamber of the fan-shaped one-tenth of frame one.Described sealing joint strip 3 bottoms are fixed on the window frame 2, and the top is pressed in the prominent along on 6 of sash 1.For the effect of preventing sealing abutment surface tension force flows into airtight chamber, be provided with at rain cape 5 places of described sash and drip, described dripping along 4 outer side-lowers at described rain cape 5 along 4; In the other sash 1 in described slit, be provided with and drip along 10; Be provided with at oblique upper sash 1 place, described sealing joint strip 3 top and drip along 9.For improving sealing effectiveness, described sealing joint strip 3 is a Duckbill type.
As further improvement of the utility model, as shown in Figure 2, can on the basis of above-mentioned embodiment, increase by one independent sealing joint strip 12, improved sealing effectiveness.Owing to increased sealing joint strip 12 one, need be provided with again in sash 1 annular seal space inboard one prominent along 11, it is prominent along last 11, so that improve sealing effectiveness that the top of the second road sealing joint strip 12 can be pressed in.A sealing joint strip 3 can certainly only be installed as required.
This programme also can be implemented by another kind of embodiment.As shown in Figure 3, the inward opening plastic window of present embodiment has sash 1 and window frame 2.In sash 1 arranged outside rain cape 5 is arranged, sash 1 is closed the back arranged outside the slit, is provided with the sealing joint strip 13 that twice link together in the chamber of the fan-shaped one-tenth of frame.Owing to the twice sealing joint strip 13 that links together is arranged, so sealing effectiveness is improved.But,, need twice to change together if any damage because this two seals adhesive tape links together.For the effect of preventing sealing abutment surface tension force flows into airtight chamber, be provided with at rain cape 5 places of described sash 1 and drip, described dripping along 4 outer side-lowers at described rain cape 5 along 4; In the other sash 1 in described slit, be provided with and drip along 10; Be provided with at oblique upper sash 1 place, described sealing joint strip 13 top and drip along 9.For improving sealing effectiveness, described sealing joint strip 13 is a Duckbill type.In order to improve heat insulation effect, the sealing joint strip 7 on the glazing bead extends on the glass block 8, makes 7 of glass and sealing joint strips form a chamber.
This use is novel to be to utilize curtain of rain principle to design.Specific to external window of building, " curtain of rain " is meant one deck water curtain that the external surface of exterior window when raining is drenched by rainwater.Because the character of water and the surface free energy of water, this layer water curtain have the characteristic that keeps its integrality and be difficult for being permeated." curtain of rain principle " is a design principle, and it points out the principle how rainwater will be prevented from the infiltration of this one deck " curtain ".This principle is applied in and mainly is meant on the external window of building in window open-part inside and will be provided with cavity, and the air pressure in the cavity is on all sites and will keep in any case equating with outdoor air pressure always, is in isopiestic state.The pressure balanced unlatching seam tight seal that is not owing to surperficial outside window of obtaining constitutes, but has a mind to make it to be in opening-wide state, and making outside window, there is not any draught head in the unlatching seam both sides on surface.
When it's raining and blowing hard air flow pressure difference was big, the intermediate seal adhesive tape was pressed on the prominent along last of sash by wind and rain, and the big more pressure of wind and rain tight more guaranteed air-tightness.And the abundant pressure balance of curtain of rain both sides, heavy rain also can't break through the curtain of rain, can only collect on the curtain of rain thickness that increases the curtain of rain, and drops on rapidly and flow away on the outside window sill, has more guaranteed watertightness performance.But by wind-induced pressure in time with all be dynamic change on the space, in the moment of fitful wind fluctuation, the pressure of curtain of rain both sides has the unequal of short time will reach balance by circulation of air, just might bring water into equivalent pressure cavity when circulation of air, the drainage system of design in equivalent pressure cavity can be discharged the water that enters equivalent pressure cavity outside window rapidly." curtain of rain principle " is applied in then is the most typical on the inward opening external window of building, also is the simplest, only needs improvement part PVC-U profile design to increase a little investment, and its rainwater leakage prevention ability will obtain obviously to improve.
