Prestressed reinforcement reinforcing system used for dome ring beam and construction method of prestressed reinforcement reinforcing system

Abstract

The invention discloses a prestressed reinforcement reinforcing system used for a dome ring beam and a construction method of the prestressed reinforcement reinforcing system. The prestressed reinforcement reinforcing system comprises an upper layer of prestressed tension structure and a lower layer of prestressed tension structure, and each layer of prestressed tension structure comprises at least one set of prestressed reinforcements. Each set of prestressed reinforcements comprises four prestressed reinforcements which are uniformly distributed in an annular array manner, and each prestressed reinforcement is horizontally arranged in the radial direction of the dome ring beam. All the prestressed reinforcements of each layer of prestressed tension structure are uniformly distributed inthe annular array manner. One ends of the prestressed reinforcements are anchored to the dome ring beam, and the other ends of the prestressed reinforcements are anchored to annular connecting pieces.The construction method comprises the steps of grouping, penetrating and anchoring the prestressed reinforcements on each layer and tensioning the prestressed tension structures on the upper layer and the lower layer in a layered manner. According to the system, the problem that connection of the dome ring beam and a wall body is prone to deforming in the related technology is solved, concrete cracks generated at the joint of the dome ring beam and the wall body are reduced, and therefore the bearing capacity of the reinforced concrete structure is improved.

Description

Technical field[0001]The invention relates to a prestressed steel reinforcement system and a construction method thereof, and belongs to the technical field of reinforced concrete structures.Background technique[0002]As the country's economy continues to improve, the proportion of natural gas as a clean energy source in the energy structure has also increased. It is estimated that by 2020, the total domestic natural gas consumption will reach 1 / 10 of the total energy consumption. Large-scale LNG prestressed storage tanks have become a widely used LNG storage facility internationally due to their large volume, small footprint, and safety, stability and durability.[0003]At this stage, the research on large-scale LNG prestressed storage tanks mainly focuses on the static analysis and seismic analysis of the tank wall, and there is very little research on the construction of prestressed outer tanks. During the construction stage, under the action of gravity and prestress of the outer ta...
