Skylighting Daylighting Atrium dome Roofing Steel Structure Project

Engineering characteristics

Hope to achieve each kind of modeling, space frame has a rhythm sense, and beautiful modeling.
The joints of roof glass or other materials are simple and convenient.
The size of the space frame structure is accurate, and the glass can be customized in advance to save installation time.
Good wind resistance, snow resistance, and earthquake resistance.

The high degree of the factory,80% of the workload is factory based and is in line with the characteristics of prefabricated building.

Solutions

Lighting roofs generally use laminated toughened glass (safety glass), such as heat insulation. sound insulation has special requirements, also can use laminated hollow tempered glass as the roof, such as the need to isolate UV energy saving and other effects as well as the need to use hollow toughened low-E glass. Materials such as highly transparent film, PE, and FRP can also be used, but the selection of materials should comprehensively consider the overall appearance, purpose of use, service life, and other requirements for appropriate matching.

The bolted connection can achieve part of the modeling, but more complex modeling, or the plant with a small amount of work due to economics When conditions permit, it is recommended to welding in at the site. But, if the amount of work is large and the shape is relatively regular, it is recommended to use a ZHM bolt connection.

There are many kinds of lighting roof materials. Each has advantages and disadvantages and must carry on the choice of matching degree. For example, the glass is more durable, but the weight is heavy and easy to self-detonation (The probability of self-detonation is related to wind force, installation level, and glass quality). Chemical material is lighter, but fire resistance and durability are generally poor.
If adopts site welding and block material (e.g. glass), the lighting materials should be re-sized and ordered after completion. BJMB structure generally, the error installation is small, and can be ordered in advance, but if the volume is large, and the error cannot be avoided, it is better to order after installation.

BJMB structure has rigidity and flexibility, and factory manufacturing; safety performance is better than site welding structure.

Process description

1. Design process:

The lighting roof requires shape and is very safe. It should be fully considered as a variety of possible load combinations when designing. Increase the safety coefficient to prevent any hidden danger that may not have been foreseen.

2. Production process:

Factory machining, welding production, very high precision, component miniaturization, easy to transport.

3. Installation process:

If the lighting roof is on the top floor roof, be sure to consider the installation method as far as possible with the help of existing conditions. Avoid large machinery, and the centralized placement of members on the floor must be prevented. If the weight of materials placed on the roof is more than the load that the floor can bear, it will cause danger.
