Abstract

The invention provides a steel pipe high-strength concrete column joint for beam-column connection and a manufacturing method thereof. The high-strength concrete steel tube column joint is composed of two parts: the column body and the joint section; the manufacturing method of the steel tube high-strength concrete column joint is that the joint section includes the joint section steel pipe, pull ring, pressure ring and piercing web, and the column body includes the steel pipe and flange of the column body section Ring; during installation, the end face of the pull ring and the end face of the pressure ring of the node section are respectively fitted with the end face of the flange ring of the column body, and the node section is connected with the column body by high-strength bolts. The steel pipe high-strength concrete column joint has reasonable stress, clear force transmission, good reliability, convenient construction, and easy control of welding quality.

Description

(1) Technical field [0001] The invention relates to a steel pipe high-strength concrete column joint used for beam-column connection and a manufacturing method thereof, which belongs to the manufacturing technology of steel pipe concrete structures. (2) Background technology [0002] Concrete filled steel pipe is a new type of composite structural material with high bearing capacity, good plasticity and toughness, cost saving, and convenient construction. It has been used in industrial and civil construction projects for many years, and has achieved good technical and economic benefits. Steel tube high-strength concrete is a component that uses high-strength steel plates rolled together with high-strength concrete above C60 to work together. Its failure state and working mechanism are similar to steel tube ordinary concrete, but its strength has been greatly improved. Elasticity The working range is increased, and the ductility requirements of the structure can be fully met ...
