Embodiment Construction

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.

[0025] Fig. 1 is the specific structural diagram of the joint structure of the concrete-filled steel pipe column and the reinforced concrete beam. 4. Beam main reinforcement thread sleeve 5, beam main reinforcement 6. 4 I-shaped dark piercing steel corbels 2 pass through the steel pipe 1 and intersect and weld in the pipe, the ring reinforcement 3 is welded on the upper flange of the steel corbel 2, and 7 plates The surface radial ribs 4 are evenly distributed between the beams and extend to the bottom of the floor slab; the double-sided fillet welds of the threaded sleeve 5 are welded to the flange at the upper end of the steel corbel, and are on a straight line with the main ribs 6 of the beam.

Abstract

The present invention discloses one kind of node structure for steel core concrete column and reinforced concrete beam and its forming process. The node structure includes feed-through bracket penetrating through and welded to steel pipe, ring rib welded to steel bracket outside the steel pipe, plate radial rib bent and hooked to the ring rib and main spiral rib sleeve welded to the end of the steel bracket. The forming process of the node structure includes calculating size of steel bracket, determining radial rib number and diameter and ring rib diameter, welding in plant, in-site tying of steel bars, and pouring concrete. The node structure has determined force transfer, capacity of controlling the crack development effectively, convenient construction and excellent engineering application foreground.

Description

technical field [0001] The invention relates to the field of structural engineering in civil engineering, in particular to a joint structure of a steel pipe concrete column and a reinforced concrete beam and a construction method thereof. Background technique [0002] Since the mid-1960s, CFST has been introduced into my country, and has been widely used in the construction of high-rise and super high-rise buildings and long-span bridges due to its superior mechanical properties. On the one hand, due to the restraining effect of the steel pipe on the filled concrete, the concrete is in a stress state of three-dimensional compression, so that its compressive strength can be fully exerted; on the other hand, due to the filling effect of the concrete, the buckling resistance of the steel pipe under the action of axial force is improved. ability. This very reasonable material combination of steel tube concrete structure can give full play to and utilize the characteristics of s...
