Ring beam is a kind of concrete beam member with closed reinforcement along the horizontal direction of masonry wall at the elevation of roof, window top, floor, crane beam top or foundation top surface of the house.
Difference 1:
The outward projection of the window sill beam can be made into a beautiful shape, which is also convenient for installing windows, and at the same time, it protects the bricks under the concrete to prevent rainwater from infiltrating and damaging.
Ring beam is a continuous closed beam along the external wall of a building and a part of the internal transverse wall. Its purpose is to enhance the overall stiffness of the building and the stability of the wall.
Difference 2:
Generally, the sill beam is arranged at the lower part of the window and closed discontinuously, while the ring beam is arranged at the upper part of the window and closed continuously.
Whether to set ring beams on each floor should be determined by the design department according to the seismic intensity of the building area and the seismic design grade of the building.
Difference 3:
Ring beam can reduce the adverse effect of uneven settlement of foundation or large vibration load on buildings and the wall cracking caused by it. In seismic fortification areas, it is more necessary to strengthen the wall with ring beams. The sill beam does not have this function.
Extended data:
In masonry buildings, closed reinforced concrete beams are set in the masonry along the horizontal direction to improve the spatial stiffness of the building, increase the integrity of the building, improve the shear and tensile strength of the masonry building, and prevent the building from being damaged by uneven settlement of the foundation, earthquake or other large vibration loads.
The continuous reinforced concrete beam on the foundation of a building is called the foundation ring beam, also called the ground ring beam (DQL); In the upper part of the wall, the reinforced concrete beam close to the floor is called the upper ring beam.
Ring beam is called ring beam because it is a continuous closed beam.
Ring beam is a kind of concrete beam member with closed reinforcement along the horizontal direction of masonry wall at the elevation of roof, window top, floor, crane beam top or foundation top surface of the house.
Ring beams are usually arranged at foundation walls, cornices and floors, and their number and position are related to the height, floors, foundation conditions and seismic intensity of buildings.
Lintel is a common component in the doors and windows of masonry buildings, which is used to bear the weight of masonry above the top of the hole and the load from the upper floor.
