CN2479110Y - Ventilating device for roof - Google Patents

Abstract

The utility model discloses a roofing ventilating device. The roofing is composed of dual steel plates, and the steel plates are respectively provided with airflow orifices and air conducting grooves. The dual steel plates are arrayed with a stagger. Because the roofing is composed of steel plates with air permeability, according to the principle of free convection, thereby the hot gas and exhaust gas in workshops can be discharged from rooms timely without providing ventilation cowls, further large amounts of energy source is saved, comfortable environments are maintained and the production efficiency is improved.

Description

The Ventilating for roof device

The utility model relates to a kind of Ventilating for roof device that is applied to factory building.

As shown in Figure 1, the Ventilating for roof device of traditional factory building is that cowl B ' is set on factory building A ', and then the hot gas that distributes of waste gas in the factory building and thermal source C ' is discharged factory building by abat-vent A ' fully.But this Ventilating for roof device has following shortcoming:

1, cowl expends electric power, the consumption energy.

2, because the interior convection effects of factory building is poor, then the hot gas dissipation is too late, and operating environment is sultry; Waste gas can't in time be discharged, and operating environment is bad.

3, staff's mood and healthy influenced.

4, if the outside rainwater is excessive, then the rain phenomenon of wafing in the factory building can take place.

The purpose of this utility model provides a kind of energy conservation and ventilates smooth and easy, uniform Ventilating for roof device.

For achieving the above object, solution of the present utility model is: the Ventilating for roof device, wherein roofing is made of double-layer plate, is respectively equipped with air vent and guiding gutter on the steel plate, the double-layer plate placement of staggering.

After adopting such scheme, because roofing is to be made of ventilative steel plate, with the principle of natural convection, then hot gas in the factory building and waste gas can be discharged outside the room timely, need not cowl is set and save a large amount of energy, the maintenance a home from home is enhanced productivity.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is traditional factory building ventilation schematic diagram;

Fig. 2 is the floor map of the utility model steel plate;

Fig. 3 is the E portion enlarged drawing of Fig. 2;

Fig. 4 is that the D-D of Fig. 3 is to sectional view;

Fig. 5 is a free exhaust schematic diagram of the present utility model;

Fig. 6 is applied to the schematic diagram of factory building for the utility model;

Fig. 7 is a rainwater current drainage schematic diagram of the present utility model.

Shown in Fig. 2-7, Ventilating for roof device of the present utility model mainly is to be provided with double-deck ventilative steel plate 1 on the roofing A1 of factory building A, be respectively equipped with air vent 11 and guiding gutter 12 on this steel plate 1, during assembling, two-layered steel plates 1 staggers mutually, that is: the guiding gutter 12 of the position alignment upper strata steel plate 1 of lower floor's steel plate 1 upper vent hole 11.

Shown in Fig. 5,6, the hot gas that waste gas in the factory building A and thermal source C give out can utilize window (or door) A1 of factory building A with the principle of natural convection waste gas and hot gas among the factory building A to be discharged outside the room smoothly, and is smooth and easy with ventilation in the maintenance factory building A, need not consumes energy.

As shown in Figure 7, when rainy, guiding gutter 12 ventings of rainwater major part on the roofing on steel plate 1, because roofing is by double-layer plate 1 setting of staggering, the rainwater of small part is oozed by the steam vent on the upper strata steel plate 1 11 in the guiding gutter 12 that drops on lower floor's steel plate 1 and discharges outside the factory building A, then the phenomenon that leaks can not occur.Simultaneously, the roofing of double-layer plate also has good effect of heat insulation, amenity in the factory building, and production efficiency improves.

Claims (1)

1, a kind of Ventilating for roof device, it is characterized in that: roofing is made of double-layer plate, is respectively equipped with air vent and guiding gutter on the steel plate, the double-layer plate placement of staggering.
