Abstract

The utility model relates to a ventilating structure device for a varnished roof wave slab. The utility model is composed of a varnished wave slab, a ventilating strip, etc., wherein, the left side of the varnished wave slab is an extended and heightened circular arc, and the empty part of the edge forms a ventilating opening. The U-shaped ventilating strip is sheathed in the ventilating opening, and the outside of the ventilating strip is provided with a plurality of ventilating windows. Each ventilating window is provided with a plurality of ventilating shutters, and the inner layer of each ventilating shutter is provided with a ventilating net. The right side of the varnished wave slab is provided with a small circular arc. When the small circular arc is lapped with the circular arc of the left side of the varnished wave slab in a matching way, a ventilating seam is formed. The edge of the small circular arc is concavely provided with a circular arc with an appropriate angle toward the inside. The device can exhaust the indoor hot air and clean the indoor air. The utility model has the advantages of low cost, long service life and beautiful appearance.

Description

Roof baking vanish wave plate ventilating structure device

The utility model relates to a kind of roof baking vanish wave plate ventilating structure device.

Now, the factory building of steel structure has installed attic type transom or heat insulation foam for eliminating the hot gas in the factory.Because attic type transom cost height, wind surface is big, the loss percentage height; And heat insulation foam can only be heat insulation, but the hot gas in the factory building can't be discharged, and hot gas can only be accumulated in the factory building top, makes the air in the factory building become muddy, sultry, peculiar smell is arranged on the contrary.If in factory building, install air regulator additional, at first be the waste that causes electric power, thereby strengthened cost, in addition for the factory building of steel structure, also be not suitable for using the method for air regulator.

The purpose of this utility model is a kind of roof of design baking vanish wave plate ventilating structure device, and this constructional device can shed the hot gas in the factory building, and produces cross-ventilation, to guarantee the cleaning of air in the factory building.

The purpose of this utility model realizes by following scheme: roof baking vanish wave plate ventilating structure device is made up of baking vanish wave plate, ventilative bar etc.The left side of described baking vanish wave plate is a circular arc that extension is increased, its edge part of leaving a blank forms a ventilation opening, the ventilative bar of one " U " font is inserted in it, the ventilative bar outside be equipped with distance suitably divide across several transoms, have several pages of ventilative louvres on the transom, ventilative louvre nexine is equipped with a gas-permeable nets, and there is a little circular arc on baking vanish wave plate right side, form a ventilative seam when cooperating overlap joint baking vanish wave plate left side circular arc, little arc edge is recessed to the inside simultaneously a suitable circular arc of an angle.

Roof baking vanish wave plate ventilating structure device utilizes thermal current to rise and can drive and discharge the hot air principle, promote the convection current of air in the factory building, reach the purpose of discharging indoor hot gas, cleaning room air.Because parts of the present utility model all adopt one-body molded mode, not only with low cost and long service life.Change as needs, it is very convenient to exchange old for new.Because it is handsome in appearance, so do not influence the attractive in appearance of former factory building.

Fig. 1 is an exploded perspective view of the present utility model;

Fig. 2 is a combination section of the present utility model;

Fig. 3 is the structural representation of transom in the utility model;

Fig. 4 is user mode figure of the present utility model;

Be described as follows below in conjunction with drawings and Examples:

As shown in Figure 1, roof baking vanish wave plate ventilating structure device comprises baking vanish wave plate 10, ventilative bar 20.Are circular arcs 11 that extend and increase in the left side of baking vanish wave 10, its edge part of leaving a blank forms a ventilation opening 12, and the ventilative bar 20 of U font is inserted in the part of leaving a blank of ventilation opening 12.And also there is a roundlet arc 13 that extends on the right side of baking vanish wave plate 10, and what cooperate that overlap joint goes up baking vanish wave plate left side increases circular arc 11.

In Fig. 2, Fig. 3, ventilative bar 20 outsides of above-mentioned U font be equipped with distance suitably divide across some transoms 21, transom has several pages of ventilative louvres 22, ventilative louvre nexine has one deck gas-permeable nets 23.Be to cooperate another baking vanish wave plate 10 of overlap joint, baking vanish wave plate 10 right side roundlet arcs 13 with increase circular arc 11 and overlap mutually, between form one and ventilatively stitch 15.The principle of utilizing thermal current to rise, when the hot air flow in the factory building rose to the roof, this ventilative seam 15 was equivalent to the pipeline of a ventilating air, thereby produces cross-ventilation, plays the effect that reduces temperature in the factory building.The edge of roundlet arc 13 is recessed to the inside in addition a suitable semi arch 14 of an angle.

After adopting the said structure design, not only can prevent dust, also can be rainproof.Attack as the high wind heavy rain, wind is discharged after can changeing an angle under the effect of interior concave arc 14 angles once again, and unlikelyly inwardly pours into, and rainwater then goes out along the underflow of interior concave arc 14.If when running into the big sun and be exposed to the sun strongly, because the high temperature hot gas circulation is often apart from be maximum temperature about the about chi of baking vanish wave plate, so heat wave high temperature flows can producing between baking vanish wave plate 10 1 chis under the effect of this device, and hot gas promptly is discharged between mobile.

Fig. 4 is user mode figure, and in the utility model, ventilative bar 20 is formed in one, so cost is low, long service life is easy to change.
