Abstract

The utility model discloses a novel steel pipe concrete column. A steel pipe for filling concrete is a profiled thin wall steel pipe, and each side of the profiled thin wall steel pipe is provided with a constraining pull rod. The profiled thin wall steel pipe of the utility model can be a thin wall steel pipe in a square shape, an L shape or a T shape. The minimal side length of the profiled thin wall steel pipe is larger than or equal to 150MM, and the wall thickness is larger than or equal to 8MM. The spacing of every two constraining pull rods is 100MM to 200MM; the slenderness ratio of the column (the width ratio of the length to the minimum section) is less than or equal to 30. The structures of the column and the node of utility model are simple with economical and convenient construction, and the building plane requirements are easy to conform. The utility model has the advantages of high bearing capacity, large toughness, light weight, good plasticity, good toughness, good impact resistance, good fatigue resistance property, good shock resistance, etc.

Description

A kind of novel steel tube concrete column

The utility model relates to a kind of building structural element, relates to a kind of concrete filled steel tubular member specifically.

As a kind of brand-new structural shape, existing smooth bar pipe concrete coupled column have many reinforced concrete structures and steel work the advantage that can not compare.Because it has the bearing capacity height, rigidity is big, in light weight, plasticity, good toughness, advantages such as shock resistance and anti-fatigue performance are good, anti-seismic performance is good, encased structures just little by little is applied to each field of civil engineering such as highrise building, bridge engineering, unique construction, its practicality and superiority are also more and more obvious, have goodish application prospect.Know from having the data document both at home and abroad, round steel pipe concrete column theory is a comparative maturity, but round steel pipe concrete column shape is single, be difficult to satisfy changeable building function requirement, its construction requirement and cost are higher simultaneously, and the joint structure of cast-in-situ steel reinforced concrete beam is complicated, has limited being extensive use of of concrete filled steel tubular member to a great extent.

The purpose of this utility model is to provide a kind of novel steel tube concrete column for solving the deficiency of round steel pipe concrete column in the construction use, and its post and joint structure are simple, construction economy convenient, be easy to meet the architectural plane requirement.

The purpose of this utility model is achieved in that a kind of novel steel tube concrete column, and being used for the concrete steel pipe of filling is the special-shaped thin wall steel pipe, is provided with binding bar on each limit of special-shaped thin wall steel pipe.

Special-shaped thin wall steel pipe described in the utility model can be square, L shaped or T shape thin-wall steel tube; The minimum length of side 〉=the 150mm of special-shaped thin wall steel pipe, wall thickness 〉=8mm; The spacing that binding bar is set is 100～200mm; The slenderness ratio of the post ratio of smallest cross-sectional width (length with)≤30.

Basic principle of the present utility model is: by concrete filled the cripling pattern of steel pipe is changed, and the drawknot effect of binding bar reduces the distortion of steel pipe walls, thereby strengthen the stability and the ductility of steel pipe walls; Simultaneously, by cuff (constraint) effect of steel pipe and binding bar, make core concrete be in the three dimension stress state, thereby make core concrete have higher compressive strength and deformability core concrete.

The utlity model has following advantage:

(1) convenient construction, when being specially adapted to cooperate the basement reverse construction as the vertical support member of shear wall core tube, reduction of erection time significantly;

(2) because the raising and the shape of columns bearing capacity are carefully and neatly reasonable, avoid thick wall, fat post on the structural configuration, reduced the sectional area of vertical member, improved the building area utilization rate;

(3) special-shaped steel pipe concrete post and conventional reinforced concrete post structure compared weight reduction and save foundation cost, and, saved the man power and material again because need not install and stripping;

(4) because the special-shaped steel pipe concrete post is big littler with distortion than the rigidity of ordinary concrete post and concrete-filled circular steel tube column, thereby improve the integral rigidity and the compatibility of deformation ability of highrise building, helped structural seismic;

(5) the special-shaped steel pipe concrete post is applied to help in the construction work industrialization, standardization and the raising workmanship of constructing and producing;

(6) the special-shaped steel pipe concrete post is strong to the applicability of fire proofing material, adopts sheet material, masonry and spraying all feasible, the fire protection expense less expensive of steel work.

Below in conjunction with drawings and Examples concrete structure of the present utility model is described in further detail.
