Description

Inner diaphragm-outer diaphragm square concrete-filled steel tube column and steel beam cross joint structure

technical field

The utility model belongs to the field of construction engineering and relates to a cross joint structure of an inner partition-outer partition square steel pipe concrete column and a steel beam.

Background technique

With the development of building structures, the research and application of steel-concrete composite structures has been rapidly developed, and has become a recognized new structural system, which is juxtaposed with steel structures, wood structures, masonry structures and reinforced concrete structures, and Expanded to become the fifth largest structure. The steel-concrete composite structure gives full play to the material mechanical properties of the concrete under pressure and the steel under tension. Secondly, the application of steel is also conducive to reducing the excessive cross-section of the concrete structure, and the strong effect of the concrete material on the steel can reduce the steel structure. Requirements for fire protection. In addition, the above combined structure is also beneficial to the improvement of the anti-seismic performance. At present, steel-concrete composite structures, that is, steel-concrete composite structures, are widely used in many countries, and the domestic development is relatively rapid.

At present, the joint forms of the square concrete filled steel tube columns and steel beams in my country mainly include the outer diaphragm type, the inner diaphragm type and the diaphragm through type. Among them, the outer diaphragm type and the inner diaphragm type have their own advantages and disadvantages; the outer diaphragm inherits the characteristics of simple connection with the steel beam, and the inner diaphragm can effectively transmit the tension and pressure of the upper and lower flanges of the steel beam; because The inner partition and the outer partition are used independently, which cannot transmit the tension of the beam end well. The diaphragm through joint requires that the square steel pipe concrete column be cut off at the corresponding position of the upper and lower flanges of the steel beam, and the original square steel pipe is re-welded after the diaphragm is welded to the corresponding position. The construction of this kind of joint is complicated, and the weld seam is relatively concentrated, so it is rarely used in our country. It is an objective requirement to develop a new form of connecting nodes.

Utility model content

The purpose of this utility model is to provide a new inner partition-outer partition square concrete-filled steel tube column and steel beam cross joint structure, which overcomes the technical defects of the square steel tube concrete column and steel beam joint in the prior art.

For achieving the above object, the solution of the present utility model is:

A new type of inner diaphragm-outer diaphragm square concrete-filled steel pipe column and steel beam cross joint, which is composed of a square steel pipe concrete column, steel beam and force-transmitting members. It is a new type of joint form with simple structure, clear force transmission and simple construction. . The square steel pipe concrete column includes square steel pipes and concrete poured inside the square steel pipes; the steel beams include upper and lower flanges and webs; the force transmission members include inner diaphragms, outer ring plates, horizontal and Vertical connection plate; the upper and lower flanges of the horizontally arranged steel beams are respectively connected with the outer ring plate of the same width as the column through the horizontal connection plate through high-strength bolts, and the web plate and the vertical connection plate welded on the side of the square steel pipe concrete are connected through high-strength bolts Connection, the outer ring plate is welded to the side of the square steel tube concrete column; the inner partition and the outer ring plate are welded on the same horizontal plane.

The section form of the concrete-filled steel tube column is square; the steel beam is an I-beam; the concrete is ordinary concrete, high-strength concrete or self-compacting concrete.

Due to the adoption of the above scheme, the utility model has the following beneficial technical effects:

The utility model has the advantages of simple node structure, convenient processing and installation, clear and reliable force transmission, and adapts to the needs of industrialized production.

The node structure of the utility model combines the form of the inner partition and the outer ring plate in a certain sense, which is more conducive to force transmission; the welding of the inner partition can effectively transmit the tension and pressure of the upper and lower flanges of the steel beam; the welding of the outer ring plate, It inherits the simple connection between itself and the beam.

The node design method of the utility model is clear and reasonable, and the construction steps are simple and easy.
