First, what is a ring beam?
1. The closed reinforced concrete in the building is placed horizontally on the stone body. In order to improve the spatial stiffness of the building, increase the integrity of the building, increase the shear strength and tensile strength of Shi Zhuan, and prevent the building from being damaged due to unbalanced foundation, earthquake or other large vibration loads. The continuous reinforced concrete beam at the top of the building foundation is called the foundation ring beam, while the reinforced concrete beam at the top of the wall near the floor is called the upper ring beam because it is a continuous ring beam.
2. The definition of ring beam refers to the continuous reinforced concrete beam of building foundation, also known as ground beam. When it is on the wall, the reinforced concrete beam near the floor is called the top ring beam. Ring beam is a kind of closed reinforced concrete beam member, and its structure is set at the height of cornice, window roof, floor slab, crane beam roof or building foundation roof along the horizontal direction of brick wall.
Second, what is the role of the ring beam?
1. The main function of the ring beam is to increase the spatial stiffness of the building, increase the integrity of the building, and increase the shear strength and tensile strength of the brick. The ring beam is actually the same as the outside of the bucket ring.
2. In the earthquake-free reinforcement area, the main function of ring beam is to enhance the overall stiffness of stone structure building and prevent the building from being affected by uneven settlement of foundation or large vibration load.
3. In the earthquake area, the main function of ring beam is to improve the connection between vertical wall and transverse wall and improve the integrity of the house. As a corner member of the floor, the horizontal height of the floor can be increased. Reduce the free length of the wall. In order to improve the stability of the wall, prevent the oblique cracks and expansion of the wall, improve the shear strength of the wall, and reduce the influence of uneven settlement of the foundation on the house during the earthquake. Because the stress of circular beam is complicated, ordinary circular beam should be treated according to the structural requirements.
4. Sometimes, in order to improve the seismic performance of multi-storey brick structures, it is formally required to set reinforced concrete columns in appropriate brick parts of the building and connect them with ring beams to enhance the stability of the building. This kind of reinforced concrete column is usually called building column.
5. Round beams play a role in multi-storey brick houses, floor frames and internal frame bricks. Because the building column is connected with the adjacent vertical wall and teeth, the function of strengthening the connection between vertical columns is to connect two phases (six sections) every 500mm along the wall height, and the reinforcement on each side extends into the wall more than100 mm.
6. Brick wall shall be built first, then concrete column shall be poured during construction, and the connection of horizontal wall shall be increased to improve the shear bearing capacity of brick 10%-30%. Restrain wall cracks and limit the occurrence of cracks.
7. If the cooperation between constructional column and ring beam can split the brick and surround it, when the brick breaks, the crack should be within the closed range to prevent further expansion.
The above is a detailed introduction to what a ring beam is and what its function is. Everyone must know something about the ring beam. In this small series, it is better to invite some professionals to build houses, because they know something that people usually don't pay much attention to, and they also know the detailed steps. If.
