Concrete member and steel support H-shaped embedded connection joint

Abstract

The invention provides a concrete member and steel support H-shaped embedded connection joint. The concrete member and steel support H-shaped embedded connection joint is arranged between beams and columns of a house. The concrete member and steel support H-shaped embedded connection joint comprises concrete member parts and connection joint parts, wherein each concrete member part comprises concrete beam inner longitudinal bars, concrete beam inner stirrups, concrete column inner longitudinal bars, concrete column inner stirrups, a first steel plate and a second steel plate; each connection joint part comprises a first support connection joint plate, a second support connection joint plate and steel supports; and both ends of each support steel are respectively and mutually connected with the connection joint parts. The concrete member and steel support H-shaped embedded connection joint is characterized in that the corresponding concrete member part also comprises third steel plates. The third steel plates are located between the first steel plate and the second steel plate; one ends of the third steel plates are connected with the first steel plate; and the other ends of the third steel plates are connected with the second steel plate.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an H-shaped pre-embedded connection node between a concrete member and a steel support applied between a beam and a column of a house to strengthen the supporting force of the house structure. Background technique [0002] Reinforced concrete frame structures are widely used and have a history of hundreds of years, and have the following advantages: [0003] (1) Take local materials. In reinforced concrete structures, sand and stones account for a large proportion, while cement and steel bars account for a small proportion. Sand and stones can generally be provided near the construction site. [0004] (2) Durable and fire-resistant. The steel bars are buried in the concrete, and the concrete protection is not easy to rust, thus improving the durability of the structure. When a fire occurs, the reinforced concrete structure will not be burned like a wooden structure, nor...

AI Technical Summary

Problems solved by technology

Although less heavy than steel, the cross-sectional size of the structure is larger, so its self-weight far exceeds the weight of a steel structure of the same span or height

[0007] (2) poor crack resistance

The tensile strength of concrete is very low, therefore, ordinary reinforced concrete structures often work with cracks

Although the existence of cracks does not necessarily mean that the structure is damaged, it affects the durability and aesthetics of the structure

When the number of cracks is large and wide, it will also create a sense of insecurity.

[0008] (3) The energy dissipation performance is not as superior as steel structure

[0011] However, the existing steel support and concrete connection joints need to embed section steel in the concrete member, and the construction is difficult. The arrangement of steel bars in the concrete conflicts w
