Concrete beam and steel column connection structure

Technical Field

The utility model relates to the field of assembly type buildings, in particular to a connecting structure of a concrete beam and a steel column.

Background

In the field of buildings, the demands of people on building industrialization are changed silently, concepts such as green buildings, sustainable development, energy conservation and emission reduction are gradually deeply paid attention to, and the conversion from the traditional extensive building production mode to intensive building becomes a key problem facing the current building industry. Under the background of the large environment, the assembly type building not only breaks through the limitation in the traditional house construction process, provides effective guarantee for the construction quality of the building engineering by utilizing advanced technical means, but also can effectively solve the phenomenon of labor resource shortage in the building market. Currently, the structural form of the fabricated building is mainly divided into fabricated concrete building and fabricated steel structure construction. Because the construction price of the fabricated concrete is relatively low, the fabricated concrete is widely applied to actual engineering.

In the prior art, the concrete beam is connected with the box-type steel column, and a steel column is generally perforated, so that longitudinal bars of the concrete beam directly penetrate through the steel column. This connected mode has more problems, if there is the construction gap between the concrete beam box steel column, and beam-ends cross-section shear strength is difficult to satisfy the atress requirement etc. influences assembled building life.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a concrete beam and steel column connecting structure, which can prolong the service life of an assembly type building.

The purpose of the utility model is realized as follows: the utility model provides a concrete beam and steel column connection structure, including concrete beam and box steel column, concrete beam and box steel column hookup location are equipped with the steel corbel, on indulge the muscle, indulge the muscle down, shear reinforcement and peg, the steel corbel is the I shape, including upper limb listrium, web and bottom flange board, steel corbel welded fastening is on the box steel column, on indulge muscle inner and upper limb listrium upper surface welded fastening, indulge muscle inner and bottom flange board upper surface welded fastening down, shear reinforcement includes vertical part and horizontal part, the vertical part is close to concrete beam and box steel column hookup location setting, the horizontal part outwards extends along the vertical part upper end, the peg sets up on the reinforcing bar inboard and vertical welding fixes on the box steel column that shears. The connecting structure of the concrete beam and the steel column has high shear strength and strong bearing capacity, and can effectively improve the structural reliability of the connecting position of the concrete beam and the steel column.

As a further improvement of the utility model, the inner side of the shear steel bar is provided with an upper transverse bar and a lower transverse bar, the upper transverse bar is positioned on the upper side of the upper longitudinal bar, and the lower transverse bar is positioned on the lower side of the lower longitudinal bar, so that the deformation of the connecting position is further prevented.

As a further improvement of the utility model, the inner ends of the upper longitudinal rib and the lower longitudinal rib extend into the box-type steel column and are welded and fixed with the box-type steel column, so that the structural strength of the connecting position is improved.
