Description

Technical Field

[0001] The utility model relates to the technical field of building steel structures, in particular to a box-type steel beam-column connection structure and system. Background Art

[0002] Steel concrete columns are widely used in large buildings due to their high strength, good seismic performance, high stability, high structural rigidity, fire resistance, corrosion resistance, and high space utilization. There are many ways to connect steel concrete columns and beams, each of which has its own unique characteristics and scope of application. The following are several common connection methods: Bolt connection: The steel beam and steel column are connected together by bolts. This connection is convenient and detachable, but requires regular inspection and maintenance; Anchor connection: The steel column is fixed to the foundation or concrete structure by anchors, and then the steel beam and steel column are connected together. This connection method is firm and reliable, but requires professional anchoring technology and construction; Welding connection: Steel beam welding generally uses CO2 gas shielded welding or manual welding. The connection strength is high, but care should be taken to prevent welding deformation and residual stress during welding; Bolted connection: The bolting of steel pipe columns and steel beams is generally divided into two types of connections: ordinary bolts and high-strength bolts, which also have high connection strength.

[0003] In order to improve the structural strength between the column and the beam, a corbel structure is usually set on the side of the column to install the beam. However, the existing steel corbel structure is mostly used in pure steel structures, and the cross-section is mostly H-section or box-type corbel. If used in steel concrete, the concrete at the connection is prone to cavity during the pouring process, affecting the structural strength.

[0138] After the reinforcement unit is tied around the longitudinal support structure 100, the template is placed against the first connecting element 251 for support to form a columnar mold body;

[0139] The cast-in-place structure 400 is poured into the interior of the columnar mold body, and the cast-in-place structure 400 is vibrated by a vibrator attached to the outside of the mold body, so that the cast-in-place structure 400 enters and fills the cavity unit 230 through the grouting element 241, thereby enhancing the compactness of the cast-in-place structure 400 in the mold body;

[0140] After the cast-in-place structure 400 is formed, the formwork is removed, the third support element 261 is welded to the outer side of the first connection element 251, and then the transverse support element is installed and fixed to the second connection element 272 by reinforcing bolts.

[0141] The advantage of the utility model is that by arranging a grouting unit on the first supporting unit, the cast-in-place structure can be densely filled in the cavity unit, thereby ensuring the structural strength of the column structure. At the same time, a first connecting unit is arranged at the second end of the first supporting unit to connect the second supporting unit, which is more convenient for formwork and construction, and solves the problem of cavities being easily formed during concrete pouring due to the corbel structure being arranged on the steel concrete column.

[0142] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
