Abstract

The utility model relates to a beam-column connection used in building frames, which is characterized in that: the utility model comprises upper and lower steel tube confined concrete columns and a reinforced concrete beam horizontally arranged between the upper and lower steel tube confined concrete columns; the steel tube confined concrete columns are made of steel tubes with concrete poured inside; the reinforced concrete beam is arranged inside with a vertical steel bar passed-through joint section; the joint connecting section of the upper and lower steel tubes is added with a reinforced skeleton frame composed of a longitudinal steel and a stirrup; the upper and lower ends of the reinforced skeleton frame are respectively extended inside the upper and lower steel tubes, thus connecting into a whole with the steel tube confined concrete columns. The utility model not only has a high bearing capacity and a good vibration-resistant performance but also has a simple structure, a convenient construction and a strong value in popularization and application.

Description

The beam-column connection that adopts in the building frame

Technical field

The utility model relates to the beam-column connection that adopts in a kind of building frame.

Background technology

So-called steel tube confined concrete column is meant fill concrete in steel pipe, but when stressed, steel pipe is not born longitudinal load, only plays confined concrete.Compare with reinforced concrete upright column, no longer join reinforcing bar in the pipe of steel tube confined concrete column and steel pipe itself can be made template, convenient construction; For the concrete filled steel tube column, when stressed, bear longitudinal load jointly, the mechanical behavior complexity of steel pipe owing to form the steel tube and tube inner concrete of concrete filled steel tube column; And the steel tube confined concrete column because steel pipe does not directly bear longitudinal load, can be brought into play the performance of material more fully.Studies show that both at home and abroad: steel tube confined concrete axial compressive strength bearing capacity is totally than steel concrete height.The shock test of its member shows that the steel tube confined concrete column has better anti.

Summary of the invention

The purpose of this utility model is that the beam-column connection that adopts in a kind of building frame will be provided, and this node not only bearing capacity height, anti-seismic performance is good, and simple structure, easy construction.

Of the present utility model being characterised in that: comprise upper and lower steel tube confined concrete column and cross at reinforced concrete beam between the upper and lower steel tube confined concrete column, described steel tube confined concrete column has concrete steel pipe to constitute by internal casting, longitudinal reinforcement in the described reinforced concrete beam body connects node area, described upper and lower steel pipe has additional the cage of reinforcement of being made up of longitudinal reinforcement and stirrup in the node joint area, the upper and lower end of described cage of reinforcement extends to respectively in the upper and lower steel tube body, links into an integrated entity with upper and lower steel tube confined concrete column.

The beneficial effects of the utility model are: both kept the good resistance shock stability of conventional steel concrete column connected node, had the good construction property of steel concrete beam connecting node again.Thereby when giving full play to material property, help constructing operation again, reduce construction costs.Along with the extensive use of encased structures in engineering practice, the node that the utility model proposed has the good engineering application prospect.
