An inclined beam, that is, two beams with unequal heights, is called an inclined beam. .

Cross beams, that is, transverse beams, are perpendicular to the columns and arranged along the short axis of the building.

Purlins, that is, purlins and trusses, are horizontal roof beams perpendicular to roof trusses or rafters to support rafters or roofing materials. Purlins are transverse bending (usually bidirectional bending) members, which are generally designed as single-span simply supported purlins. There are two commonly used purlins: solid purlins and light steel trusses.

Kanban, also called roof panel, is a wooden board laid on rafters to support roof tiles. It can also be nailed directly to the purlin. Waterproof layer, thermal insulation layer, thermal insulation layer and ceramic tile are generally laid on it.

Data expansion:

1. Pavilion is a traditional building in China, which is mostly built in gardens, Buddhist temples and temples. Buildings built on the roadside or in the garden for people to rest, shelter from the rain and enjoy the cool are very small, and most of them only have roofs and no walls. Pavilion is also a kind of garden sketch, which is used to decorate the garden landscape.

2. Most materials are wood, bamboo, stone and reinforced concrete. In recent years, glass, metal and organic materials have also been introduced into this kind of building, which makes the exhibition hall, an ancient architectural system, have a modern fashion sense.

3. The status of building a museum should be considered from two aspects: one is to look good from the inside out, and the other is to look good from the outside in. The garden pavilion should be built in a place with good scenery, so that people who rest can enjoy the scenery and stay there. At the same time, we should also consider that the pavilion will become a beautiful garden after it is built. Gardens can often play the role of finishing touch here.
