In this shutter, neighbouring described louver 1, the fixed part 1A4 of upper louver 1 windward side lower than under louver 1 on the upper end of curved surface plate body 1A3 below.
In shutter, the two ends of the triangular prism cylindrical shell of described louver are separately fixed on a louver munnion 3, as shown in Fig. 1, Fig. 7 and Figure 11 and Figure 12, be provided with a screw 1a at A place, the summit of louver 1, on the inner surface of the sidewall relative with summit A, be provided with another screw 1c.When assembling, the screw 4 wearing on louver munnion 3 is screwed onto in screw 1a and screw 1c, and the two ends of louver 1 are fixed on louver framework.Two described screws can be open type screws.
This highly-breathable weather proof louver production and processing installation process can be to carry out according to following technique:
1, the making of louver, first the louvre blade of processing composition each sidewall of louver 1 and the plate body of extension thereof, size, the shape etc. of area, perforated percentage and the perforation of louver is the balanced design that requires inflow and water leakage according to ventilation, and the louver that meets processing length dimensional requirement is carried out to 90 degree cutting stocks.
2, the processing of louver transverse frame of window, munnion, by horizontal the louver that meets processing length dimensional requirement frame and munnion, by 90 degree cutting stocks, each louvre respectively needs each one of two of munnions and upper and lower frame.
3, group frame, is assembled into louvre (as shown in figure 10) by the louvre framework of lower good louver and surrounding,
4, install.Louvre is transported to job site according to the requirement of Curtain Wall Design, is installed in the facade lattice of appointment, the fixed form of surrounding is identical with common louvre, no longer narrates at this.
The shutter that the utility model provides is a kind of ventilated efficiency and anti-racking into all good louvres of performance of rainwater, specifically: be exactly by one group of novel aluminum alloy louver design, compared with traditional aluminium alloy louver, be only by the louver of aluminium alloys carry out innovative design with regard to realized high efficiency and ventilated and possess conventional louvre necessary rainwater-proof waft into function, ensureing under the prerequisite of the weather-proof basic function of conventional louvre, strengthen the ventilation of unit area louvre, simultaneously by the design of different gravity vents and ventilation ratio, can meet the needs that distinct device ventilates.
The utlity model has following advantage:
1, high air permeability, what provide by the utility model is for example the louver that aluminium alloys is made, and processes the gravity vent of difformity, different densities on three faces of louver, realizes the high drafting efficiency of louvre.As shown in Fig. 1 and Figure 13, the A of louver to B to the drafting efficiency that is mainly used in increasing louver.The louver that the utility model provides ventilates from A upwards bores a hole, and air permeability is far away higher than existing shutter, and the drafting efficiency of unit area improves 50-100% left and right than conventional louver.
2, high weather proof performance.The most basic function of louver is exactly weather proof, avoid rainwater to waft into indoor, conventional louver all can have a small amount of raindrop to waft into indoor for larger wind and rain, this louver has high performance weather proof function, as shown in figure 14, the rainwater part being blown into is that sidewall 1A and 1A1 block by windward side, direct hole 1AK1 or the 1AK2 from sidewall 1A1 of a rainwater part by the perforation on windward side flows down, by the downward-sloping windward side of lower one deck louver stop flow to outdoor, another part enters in the cavity of cylindrical shell, the speed of raindrop slows down in space, can be from sidewall 1B near the perforation 1BK of drift angle A drain to lower floor's louver inclination windward side and flow to outdoor, the rainwater being blown into may some be crossed the first barrier that curved surface plate body 1A2 forms, can be carried out second by curved surface plate body 1A3 below stops, may also have the rainwater of less amount to cross curved surface plate body 1A3, along sidewall, 1C flows down, the groove that Bei tri-roads stop stops, and run down into the downward-sloping windward side of lower floor from the bottom land perforation 1B1K of groove, rainwater on each layer of windward side finally from the lower transverse frame 23 of framework discharged to outdoor.Rainwater changes with the wind in the wind action direction that descends slowly and lightly, the utility model takes curved surface plate body 1A2,1A3 and groove three road weather proof to waft into interior design, three road rainwater-proofs are counter fills with reverse osmosis design, there is good weather proof performance, offer perforation in the place that may accumulate rainwater as drain hole, can have thus and on the basis of high air permeability, accomplish that rainwater-proof effect is not less than the feature of common shutter simultaneously.
3, high strength design.Common louver is all the design of simple one chip, and intensity is low, and the in the situation that in louver length, large or wind load being larger, louver can be significantly sagging.Not only affect attractive in appearancely, also impact is used function, and this louver increases a closed cavity, in increasing louver intensity, does not affect the use function of louver.
4, environmental protection recoverable, this louvre can all adopt aluminum alloy materials to make, absolutely recoverable.
5, industrialization processing and fabricating, when precision is high, efficiency is high.This louver has all been assembled in production department processing, is just fixed on simply at the construction field (site) on the window hole in lattice Nei Huo building of curtain wall.
The height ventilation high strength weather proof louver that the utility model provides, its design is mainly by the aluminium alloy extrusions of one group of brand-new design, realizes: 1, high performance weather proof function.2, high efficiency performance of ventilating, the drafting efficiency of unit area improves 50-100% left and right than conventional louver.
