Now, let's summarize the key issues to be aware of when designing Xiaoshan awnings:
Material
Ensure the use of tempered and interlayered glass, a combination of sheet tempered and inner semi-tempered glass. Semi-tempered glass, also known as heat-strengthened glass, shares a similar production process to tempered glass, but the wind pressure during the rapid cooling phase is lower than the standards for tempered glass. The surface stress of semi-tempered glass ranges between 24~69MPa, which is lower than that of tempered glass. Therefore, its strength and thermal shock resistance are slightly inferior to tempered glass but can be up to 1~2 times higher than regular glass. Compared to tempered glass, the advantages of semi-tempered glass include better flatness, reduced light distortion, and due to its lower stress, it does not exhibit spontaneous bursting.
After shattering, the fragments of semi-tempered glass resemble those of ordinary glass, showing through cracks without forming enclosed, small pieces at the center. This characteristic is crucial for Xiaoshan Rain篷 glass, as it prevents fragments from falling off buildings. Therefore, the inner layer of semi-tempered glass offers enhanced safety, ensuring that the glass does not sag upon breaking, maintaining both functionality and aesthetics, and guaranteeing a timely replacement.
2. Structure
The cantilevered awning wind pressure value is considered at -2.0.
Stiffness control is strictly maintained, taking into account the visual impact on humans.
3. Drainage
The canopy, which covers a relatively small area, can be designed for free drainage for a more sleek and aesthetically pleasing architectural effect.
4. Telescopic Handle Setting
The 3-meter overhanging canopy can be installed with a fixed connection, which is highly recommended, and pull rods may not be necessary.
For overhanging canopies in Xiaoshan exceeding 3 meters, it is recommended to use articulated joints to minimize fixed-end bending moments, and it is essential to install tension rods.
The rod settings can be divided into two types: A, vertical and horizontal fine rods (subject to tension), such as φ12-16 steel rods; B, installed rods (subject to tension and compression), for example: φ68×4-φ121×7.
