Description

A steel connecting structure for construction engineering

technical field

The invention relates to the technical field of construction engineering, in particular to a steel bar connection structure for construction engineering.

Background technique

Concrete structures are widely used around the world, ranging from single-family homes to multi-storey multi-family apartment buildings. Some high-rise commercial buildings and public buildings, such as conference tubes, high-rise buildings, high-rise residential buildings, shops and office buildings, also use this structural system. Concrete structure buildings have the advantages of long service life, simple construction, short construction period, personalized interior design, good thermal insulation effect, good air permeability, and earthquake resistance. In order to ensure the strength of concrete, steel bars are generally added to the concrete.

In the existing building structure, the grouting steel bar connection structure is mainly used, and the connection and installation of the steel bar is mainly performed by means of binding or sleeve. However, when connecting smooth steel bars and ribbed steel bars, the steel bar connection structure of house building is usually wound and fixed by iron wire, so that the smooth steel bars are easy to slide relative to each other, and the fixing effect is poor. , Because there is no fastening device installed, the smooth steel bars are easy to slide relative to the ribbed steel bars, thus reducing the fixing effect; when the steel wire is used for bundling, due to the small diameter of the steel wire, the bearing capacity is poor and it is easy to break. Under the action of large stress, the internal steel bars will be loosened, so that the strength of the whole concrete is poor; and most of the steel bars in the existing road and bridge construction are bundled with No. 8 wire. If it is fixed, there is no way to adjust it. If it must be adjusted, it needs to be fully opened for bundling. At the same time, the process of bundling the steel wire is also a cumbersome process, which wastes time and manpower, and delays the construction period.
