Abstract

The utility model provides a louvre window lamella with streaks and an air chamber. The louvre window lamella is formed in the extrusion foaming mode by adopting plastic material, and the surface of the lamella has concave-convex and ruleless streaks; the thickness of the same section of the louvre window lamella is different, and the thick part of the section is provided with a hollow air chamber formed in the foaming mode; the section has thin part and thick part, and non-compact connecting shape is formed. The louvre window lamella having different transparency and good decorative effect is formed.

Description

Louvre window lamellar with streak and air chamber

The utility model relates to a kind of building window with hiding decorations articles for use, particularly a kind of louver lamina that has speckle and air chamber.

The structure of louver lamina as depicted in figs. 1 and 2 at present, it is that to extrude the surface that processes by the PVC material be the lath-shaped of smooth flat, the thickness of its arbitrary section is all identical, section inside is fine and close solid, though it has the adjusting room brilliancy after the string dress gets up, cover latent close and decoration function, but still have following shortcoming:

First: because blind blade 20 adopts the fine and close solid construction of squash type, therefore, the materials amount is more, monolithic weight is big, weight is also big after the whole string group, then must consider to exist the high problem of cost because of hanging great backguy that causes and leaf box load-bearing problem when whole louvered design.

Second: because blind blade is inflammable integral plane, its interior molecules connects closely, so in case during breaking out of fire, its conduction of heat and combustion-supporting property are higher, exist to promote the drawback of burning.

The 3rd: surfacing is smooth, adds its thickness homogeneous, so see that from whole leaf table no any decorative pattern presents, decorative effect is general, and in addition, isolated property is relatively poor.

The 4th: PVC has toxicity, uses at indoor extension for a long time health and environmental quality are had harmful effect.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provides a kind of in light weight, has the louver lamina that has speckle and air chamber that anti-flammability also can present the light and shade decorative pattern.

The purpose of this utility model is to realize by following technical scheme: blind blade adopts the plastic material foam shaping by extrusion, the blind blade surface has rough random speckle, the same section thickness difference of blind blade, the hollow gas chamber that on the thick position of section thickness, has foaming to form, in same section, Bao Youhou is arranged and form the non-fine and close shape that connects, can form a kind of blind blade with good decorating effect of different light transmittances.

Therefore: remarkable result of the present utility model is:

First: after blind blade was the not equal thickness plates of non-densification, its monolithic weight descended, and the materials amount descends, so can reduce cost.

Second: the discontinuous compactness structure that thickness differs, have the discontinuous fire retardation of burning, promptly can not help to increase burning.

The 3rd: rough random speckle, can obtain different light transmittances, can produce the visual impression as the silk and promote the effect of decorating.

The 4th: the air chamber of blind blade has the conduction of heat of making and is noncontinuity, thus have the thermal resistance effect in summer, and have heat insulation effect in the winter time.

The 5th: owing to adopted the PC plastic material, its oxious component is low than PVC.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.

Fig. 1 is the outline drawing of existing louver lamina.

Fig. 2 is the sectional drawing of Fig. 1.

Fig. 3 is a plan view of the present utility model.

Fig. 4 is the part plan enlarged drawing of Fig. 3.

Fig. 5 is the section of structure of Fig. 3.

Fig. 6 is the partial enlarged drawing of Fig. 5.

Be described in detail below in conjunction with 3 to 6 pairs of concrete structures of the present utility model of accompanying drawing:

The utility model has a tabular blind blade 20, it is characterized in that curtain sheet 20 surfaces have rough irregular speckle 21, and the section thickness difference of curtain sheet 20 is distributed with the air chamber 25 that foaming forms at the section internal layout.Referring to Fig. 3 to Fig. 6

Architectural feature of the present utility model also is:

The rough irregular surface of synthetic plastic expansion type blind blade 20 is to be formed by thickness

different zone

22,23 and 24 staggered net structures, the section thickness in zone 23 is less than the section thickness in zone 22, the section thickness in zone 24 is less than the section thickness in zone 23, and air chamber 25 is distributed in 22 inside, zone and is hollow form.Referring to Fig. 3 to Fig. 6

The mechanism of the variation of the result of use that is caused by the utility model architectural feature is as follows.

As shown in Figure 3 and Figure 4: because these blade 20 surfaces present uneven irregular speckle 21, and it is thick, thin with as thin as a wafer regional 22,23,24 etc. that its section is had, because in different its light transmittance difference of zone of thickness, so that regional 24 light transmissions are best as thin as a wafer, and zone 22 light transmissions of big thickness are the poorest or light tight fully; Therefore, by day with indoor light irradiation in evening down, can present two kinds of distinct aesthetic feelings, under the daytime daylight,, cause the light transmission difference because blade is uneven surface, can present the different speckle of light and shade.When under indoor light irradiation at night, the height of face of blade reflection photosensitiveness and careful lines cause blade to present as the crepuscular vision sense as the silk.Hence one can see that, this case blade by day with night two kinds of different light rays conditions under, can present two kinds of distinct lines, be different from over the impression that all presents same level at blade daytime and night, to reach the purpose of promoting decorative effect.

Moreover, because of blade 20 surfaces have rough irregular speckle 21, it is big that its maximum ga(u)ge zone 22 is maintained with general vane thickness etc., and the relative thickness that just can make the general blade of depressed part part is little, and the while is because of having cellular air chamber 25 again between its section.Therefore, the density of blade 20 does not influence under the bridging effect keeping, and its weight is can general blade little, and relative meeting reduces material use amount and monolithic weight, can reach the purpose of saving material and cost of transportation.

As shown in Figure 6: between the cross section of this case, have most cellular air chambers 25, this air chamber 25 can make the conduction of heat of blade 20 external surfaces to inner surface, presents the noncontinuity transmission.Therefore, this case blade 20 outside the solar radiant heat of major part can being denial in, and makes and is delivered to indoor heat energy and reduces when practical application, and the effect of heat insulation of general blade is better, has preferable effect of heat insulation.In addition, because the cellular air chamber exists, can make blade when fire takes place, the characteristic of discontinuity combustion combustion is arranged, relative can reduce flammability, and burning velocity is eased up, and has preferable flameproof effect.
