Description

Truss daylighting skylight

Technical field

The invention relates to a building energy-saving ventilation device, in particular to a truss-type daylighting ventilation skylight.

Background technique

The demand for building energy-saving applications has stimulated the development and application of building natural ventilation technology products. In recent years, truss-type daylighting and ventilating sunroofs have gradually been selected by certain design and use units. A roof ultra-thin streamline type ventilator disclosed in CN201589368U and an assembled lightweight roof ventilator disclosed in CN202501595U. However, the development of conversion technology has gradually become a misunderstanding, and the original simple and economical natural ventilation product technology has become more complicated: 1. The plate-type molded-shaped material technology used is not conducive to product standardization and popularization, which is not conducive to product material selection. It is interchangeable with the application; 2. The product appearance is the use of plate-type material light-weight technology. In fact, the support of large-scale structural profiles is required to form a complete product to ensure normal use; 3. Roofing lighting and ventilation integration technology is the development trend of building energy-saving technology The truss-type daylighting and ventilating sunroof has a good foundation of light-transmitting and scattering body. However, the special-shaped material technology makes the widely used high-temperature corrosion-resistant light-transmitting material technology not applicable, thus limiting the lighting effect of the product.

The trussed daylight louver is a small unit combination similar to a large roof ventilator, and the product development is expected to achieve a similar sheltered natural ventilation function. However, the small truss-type daylighting and ventilating sunroof has a small space for internal ventilation structure, lacks the slow release function of the internal structure distance of the large ventilator, and inertial splash and unorganized dispersion caused by rain, snow, and dust from the external wind. It is easy to fall into the vents and enter the building to cause pollution. Thus, in order to enhance the windproof performance, the above-mentioned thin ventilators can only enhance the shelter by adopting a constantly changing internal structure, including increasing the structural overlap and increasing the structure exhaust flow. According to the ventilation flow formula Q= FV2 P7 mVs, a certain size of ventilation device, the overlap degree increases, the effective flow area F inside the ventilator is reduced, and the low (thin) wind shelter structure increases the ventilation resistance after the exhaust air flows. The flow coefficient ^ is reduced. These ways of strengthening the wind avoid the ventilation flow Q, that is, the ventilation performance of the product is degraded.

In order to enhance the windproof performance, the assembled lightweight roof ventilator disclosed in CN202501595U is provided with a translating valve plate device, but since the valve plate device is located at the air inlet at the bottom of the ventilator, when the valve plate is closed, the ventilator loses ventilation capacity. External contaminants are more likely to fall on the valve plate with the wind, and the falling snow melts and falls into the building, causing pollution inside the building.

The type of flashing 5 and the upper V-shaped flashings 9, the V-shaped sump 12 and the partition 13 on both sides form a trapezoidal exhaust passage having a symmetrical arrangement and having an air inlet and an air outlet. The V-shaped sump 12 and the structural truss 1 are plug-in push-pull structures, so as to periodically clean the ash of the V-shaped sump, and solve the problem that the sump ash increases the load and affects the drainage function.

On the structural truss 1, a water stop member 4 is provided at both side edges of the middle V-shaped flashing 5. On the adjacent two rows of structural trusses 1, respectively, a middle suspension damper plate 6 is respectively arranged directly above the middle V-shaped flashing plate 5, and the damper plate 6 is supported by a hinge shaft welded at the middle of the two ends thereof. On the axle seat 15 above the truss 1, the weight of the portion of the damper plate 6 below the hinge shaft is greater than the weight of the portion above the hinge shaft, so that the damper plate 6 is in a vertical state by gravity when it is opened. The adjacent damper plates 6 located above each row of ventilating units 102 are connected by a connecting plate 7, and one end of the plurality of rows of damper plates 6 are hinged to each other by a connecting rod 8 to realize the linkage between the damper plates 6.
