Reinforced concrete beam and section steel column end plate type connecting structure joint and construction method thereof

Abstract

The invention belongs to the technical field of constructional engineering, and particularly relates to a reinforced concrete beam and section steel column end plate type connecting structure joint and a construction method thereof. The reinforced concrete beam and section steel column end plate type connecting structure joint is characterized by comprising a steel bar connecting sleeve, a connecting end plate and a beam steel bar cage, wherein one side surface of the connecting end plate is connected with section steel in a section steel column; the steel bar connecting sleeve is fixed on the other side of the connecting end plate; and end steel bars of the beam steel bar cage are connected into the steel bar connecting sleeve. The reinforced concrete beam and section steel column end plate type connecting structure joint can be prefabricated and formed, construction difficulty is reduced, mounting precision is high, construction speed is high, and connection is reliable. By the optimized design of the structure, a construction process can be changed, construction is simple and convenient, the connecting end plate is matched with the connecting sleeve and is connected with the section steel column, the connecting joint has good bending resistance and tensile property, furthermore, construction cost is greatly reduced, and the reinforced concrete beam and section steel column end plate type connecting structure joint is suitable for being popularized and used in the constructional engineering industry.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a reinforced concrete beam and a steel column end plate connection construction node and a construction method thereof. Background technique [0002] Steel Concrete Structure (SRC) refers to the structure in which reinforced concrete members contain section steel. This structure is an embedded composite structure system that uses section steel as the steel frame and arranges steel bars and concrete around the section steel. Steel concrete beams and columns are the most basic components of steel concrete structures. [0003] The use of steel concrete structures in high-rise and ultra-high-rise buildings can greatly reduce the section of components and reduce the self-weight of the structure, thereby increasing the effective use area of ​​the room and conducive to the earthquake resistance of the structure. At present, the joints between concrete beams...

Problems solved by technology

However, due to the way of opening holes in the section steel, the section steel forms a stress concentration area at the opening position, which reduces the compressive performance of the section steel, and is prone to failure and damage at the opening position during an earthquake, and because the longitudinal reinforcement of the beam is bonded to the concrete form, when the longitudinal reinforcement is stressed, the stress on the longitudinal reinforcement is the largest at the edge of the steel concrete column, and a larger bonding force is required between the longitudinal reinforcement and the concrete

When the cohesive force is insufficient, there will be relative slippage between the steel bar and the concrete, and eventually bond splitting failure will occur. In addition, there is also the problem of alignment difficulties during construction
