Abstract

The invention relates to a composite frame system with beam column flanges being made of steel pipe concrete and a construction method. The composite frame system with the beam column flanges being made of the steel pipe concrete is formed by connecting composite columns with composite beams through joints. The composite beams are horizontally arranged among the composite columns. The joints are steel pipe concrete integral type joints. The composite columns are cross-shaped or I-shaped composite columns with the flanges being made of the circular steel pipe concrete. The composite beams are I-shaped honeycombed beams with the flanges being made of the steel pipe concrete. The joints and the composite columns are fixedly connected at respective connecting plates through high-strength bolts. The joints and the composite beams are connected through buffer sections which are I-shaped honeycombed beams with the flanges being made of the steel pipe concrete. The cross sections of the buffer sections are variable cross sections gradually diminished from the two ends to the centers, and the cross sections of the buffer sections are smallest at the midpoints. The problems that according to an existing steel-concrete composite structure, construction is complex, connection and stability between the composite structure are poor, and the joints are liable to damage under the earthquake effect are solved.

Description

technical field [0001] The invention relates to a building 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 made of steel tube 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. It has great application in practical engineering. limitation. 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 into a detac...
