What is shelve angle?

Shelf angle is an important component in the construction of masonry buildings. It is a horizontal structural member attached to the exterior masonry wall, which supports the weight of the vertical load above it. The angle is typically made of steel and is provided with anchor bolts, which are embedded in the masonry wall, to hold it in place.

The angle is usually placed between the floor slab or beam and the masonry wall. Its position and orientation are important to ensure that the weight of the building is evenly distributed and that the angle is not subjected to excessive stress.

The shelf angle is usually designed to resist vertical loads, lateral loads, and thermal movements. The design of the angle is based on the material properties of the supporting wall and the load it carries. The angle should be selected based on the compressive strength and stiffness of the supporting wall.

The angle is typically installed with a downward slope towards the exterior to ensure proper drainage and prevent the accumulation of water. The slope should be sufficient to prevent water from accumulating anywhere on the shelf or behind the masonry wall.

In conclusion, shelf angle is a crucial component in the construction of masonry buildings that provides support for the vertical load above it. Its design and installation should be carefully considered to ensure the safety and longevity of the building.
