What are the commonly used shading methods for glass roofs of steel structure space frames?

What are the commonly used shading methods for glass roofs of steel structure space frames?

The daylight roof of the space frame structure is generally divided into three shading methods

One is to install the sunshade products above the grid structure and below the glass, and fix the sunshade products on the glass supporting square tube. This kind of sun-shading method is installed under the glass and runs close to the glass surface. A thermal insulation layer is formed between the sun-shading curtain and the glass surface. The sun-shading effect is good. However, the installation space of this method is small and the construction is difficult.

 

The second is to choose to install the sunshade products outside the daylighting roof, that is, to make the external sunshade, so that it is not limited to the influence of the internal grid roof structure, Construction and post-maintenance are very convenient, and the external shading product directly isolates the heat from the glass, which has the best shading effect. External sunshade products can choose to use dual-motor outdoor canopy, which is suitable for sun-shading in various areas. External sunshade products can choose to use dual-motor outdoor canopy, which is suitable for sun-shading in various areas.

 

The third is the shading method installed under the space frame structure. This shading method is easier to install and less difficult to construct. But the disadvantage is that because the sunshade products are installed under the space frame, they are far away from the glass, and the plane under the lighting top of the grid is smaller than the glass plane. Part of the heat energy enters the room, resulting in unsatisfactory heat insulation effect.
