Embodiment 1

[0044] combine figure 1 , figure 2 As shown, the composite frame system with rectangular concrete-filled steel tube flanges is composed of composite column 1 and composite beam 2 connected by node 3, composite beam 2 is horizontally arranged between composite columns 1, and node 3 is an integral node of steel tube concrete. The concrete-filled steel tube integral joint is to weld the I-shaped node end beam 4 whose upper and lower flanges are rectangular steel pipes and the node end column 5 whose flange is a rectangular steel pipe. The connection between the I-shaped node end beam 4 and the node end column 5 The rectangular steel pipes communicate with each other to form a cross-shaped steel pipe integral node. The other end of the I-shaped node end beam 4 is welded with the connecting plate 6, and the two ends of the node end column 5 are welded with the connecting plate 6 respectively. The font-shaped composite beam and the cross-shaped composite column are connected, and ...

Embodiment 2

[0052] This composite frame system with beam-column flanges of rectangular concrete-filled steel tubes is composed of composite columns 1 and composite beams 2 connected by joints 3, composite beams 2 are horizontally arranged between composite columns 1, and node 3 is an integral joint of steel tube concrete, and the composite steel tube concrete The I-shaped node is to weld the I-shaped node end beam with rectangular steel pipes on the upper and lower flanges and the node end column with rectangular steel pipes on the flange. The high-strength bolts 11 can be connected with the I-shaped composite beam and the I-shaped composite column, and concrete 10 is poured into the beam column and the node at the steel pipe integral joint to form the steel pipe concrete integral joint; the other end beam of the I-shaped joint Connecting plate 6 is welded at one end, connecting plate 6 is welded at both ends of node end column 5 respectively, and concrete 10 is poured in the steel pipe in...

Embodiment 3

[0061] In this embodiment, the composite column is a cross-shaped composite column whose flange is rectangular steel tube concrete, and the joints are cross-shaped steel tube integral joints, and the others are the same as those in Embodiment 2.

[0062] The construction method of the composite frame system in which the above-mentioned beam-column flanges are rectangular steel tube concrete:

[0063]Firstly, the material is cut in the factory according to the design, and all the required steel components are welded and prefabricated, including the short steel pipe column 7 outside the combined column with the connecting plate 6 welded at one end and the other end buried in the foundation, and the combined column with the connecting plate 6 welded at both ends Rectangular steel pipe columns, the flanges of the connecting plates 6 welded at both ends are I-shaped honeycomb beams of rectangular steel pipes and integral porous nodes. The lower part of the outer steel pipe short co...

Abstract

The present invention relates to a composite frame system with rectangular concrete-filled steel tube flanges and a construction method. The composite frame system with rectangular concrete-filled steel pipe flanges is composed of composite columns and composite beams connected by nodes, and the composite beams are arranged horizontally between the composite columns. Between, the joints are integral joints of steel tube concrete, the composite column is a cross-shaped or I-shaped composite column with a rectangular steel tube concrete; the composite beam is an I-shaped honeycomb beam with a rectangular steel tube concrete; the node and the composite column are in the The respective connecting plates are fixedly connected by high-strength bolts, and the nodes and composite beams are also fixedly connected by high-strength bolts at their respective connecting plates. The invention solves the problems of cumbersome construction of the existing steel-concrete composite structure and poor connection and stability of the composite structures.

Description

technical field [0001] The invention relates to a house frame structure in the field of civil and architectural structures, in particular to a composite frame system and a construction method in which the flanges of beams and columns are rectangular steel pipe concrete. Background technique [0002] Conventional building frame structures are mostly cast-in-place welded reinforced concrete frames or steel frames, which have a long construction period, are greatly affected by the environment, and the achievable span is small, and the component bearing capacity is low, which has great limitations in practical engineering applications. sex. In recent years, with the development of buildings in the direction of faster, higher, larger span and stronger bearing capacity, conventional structural systems and construction methods are facing new challenges. People began to build structural systems with more convenient construction and stronger bearing capacity. Set the steel frame in...
