Product Details

Product Parameters

        The thin roof ventilator is a side-by-side combination of small ventilation units similar to large roof ventilators, with a height and physical technical advantage for building applications. However, the small ventilation unit has a small space for inertial slow release, and the application often causes leakage of the building due to inertial splash of rain and unorganized dispersion of snow. To this end, the thin roof ventilator constantly changes the structure type, which makes the development of the conversion technology go wrong, and the product technology tends to be complicated: 1. The molded profiled plate product technology used is not conducive to product standardization and popularization, which is not conducive to the product. Material selection and application interchange; 2, the product appearance is the use of plate-type material light body technology, in fact, must support large-scale structural base support to form a complete product to ensure normal use; 3, thin roof ventilator has a good building through Light scattering body foundation, however, the special material product technology is not conducive to the development of light-transmissive materials, which is not conducive to the development of roof lighting and ventilation integration technology. (Figure 1, Figure 2)

          

 

The truss type thin roof ventilator (Fig. 2) is developed by our company based on the imported technology. The product technology is relatively simple and practical. 1. The large-span adjustable-strength metal structure truss naturally forms a small-sized ventilation unit. The truss structure is The ventilation unit carrier is also the structural body connecting the roof foundation, and there is no need to provide a large base support structure. 2, ventilation unit rain and drainage material is a double simple V-shaped plate, you can choose any material plate processing or custom-made according to needs. 3. The product is divided into fixed wind shelter, automatic shelter and adjustable wind shelter. It has technical and economical application selection mechanism. 4. As a substitute technology for building roofing, the product has the technology extension application prospect. For large-scale high-temperature production buildings and buildings requiring seasonal lighting and temperature control, large-area lighting and ventilation applications can be realized.

 

Thin roof ventilator technology comparison

 

No. Related technology Ventilator form Technical comparison content
1 structure type Truss         The steel truss has a high load-carrying adjustable strength and a thin roof ventilator base function, eliminating the need for a separate base and reducing the number of base steel profiles and installations.
Other technology         The ventilation unit group of the plate type molding material is spliced by itself, and has a large amount of steel base support.
2 Production Process Truss         All simple and versatile production processes are easy to standardize and popularize, making it easy to manufacture material selection and application interchange.
Other technology         The special-shaped board production process and unconventional general-purpose production technology are not conducive to product standardization development, which is not conducive to product maintenance and replacement.
3 Installation process Truss         The leveling pedestal has a small construction amount, and the frame structure is simple to install, and the construction operation can be started, the construction efficiency is high, and the cycle is short.
Other technology         The construction of the pedestal is huge, the splicing combination of the ventilation unit is complicated, and the construction process is restricted to expand the operation, which restricts the construction period.
4 Ventilation and shelter performance Truss         The triple V-shaped rain-proof drainage structure with self-draining function respectively forms a ventilation unit in the form of diversion, which is good in shelter from wind, small in ventilation resistance and large in effective ventilation area. The upper exhaust vent is technically reasonable and the method is simple.
Other technology         Take the increase of flow around, reduce the ventilation size to avoid the wind, the ventilation capacity is low, and form the special-shaped production and processing of the product. The opening and closing mode at the bottom air inlet is limited in wind and snow protection.
5 Lighting function Truss         All rain-proof drainage materials are made of high-temperature resistant and anti-corrosion light-transmitting materials, which have excellent large-area architectural lighting effect.
Other technology         Shaped materials are not conducive to the manufacture of light transmissive materials.
6 Precaution and service life Truss         It has the value of recycling board materials. The upper exhaust vent is suspended in the air panel, the torque is small, the control is simple, and the maintenance is convenient.
Other technology         Does not have replacement materials to extend product use conditions. The opening and closing control is in a small space at the bottom of the device, and the installation and maintenance are inconvenient.
7 Other technical features Truss         For dusty ventilation applications, the bottom sump can be set to push-pull for regular cleaning.

 

Economic analysis of main technical indicators of products
        No need for a pedestal, it is the biggest technical advantage and economic advantage of the truss type thin roof ventilator. The following is an example to analyze its technical uneconomicality.

        For example: design 6 m vents, 2000 extended meters thin roof ventilators, other thin technology requires the configuration of 5 longitudinal span roof beam pedestals, light H300 steel, pedestal steel structural material amount 2000? 7kg = 370000kg, ie 370 tons.
        With the frame technology, the steel structure is replaced by 5 frame structures, and the weight of the leveling buttress and the support is only 190 tons.
        The difference of 180 tons, the huge difference in pedestal materials, the impact on the overall benefits of the building is far from the above-mentioned digital statistics can fully represent.

 

Product structure and application classification
The product structure includes: structural truss, outer guard, one layer of flashing, two-layer flashing, sump, partition, flooding board, etc.
Product classification: According to the application building environment, the product is divided into three types: fixed shelter, automatic shelter and adjustable shelter.
