Abstract
The utility model relates to a direct assembled steel pipe concrete combination special-shaped column, which comprises steel pipes, dumbbell-shaped lace pieces, stiffeners, bolts and concrete. The steel pipes are connected directly through dumbbell-shaped lace pieces to be the steel pipes combined special-shaped columns with L shaped, T shaped or cross-shaped cross sections, which are completed bypouring concrete into the steel pipes. The utility model has the benefits that the column is covered in the wall body, which prevents the formation of convex angles on the indoor corner parts; the interval between the single steel pie is adjustable, therefore a relatively high bending rigidity can be obtained by adopting a small cross-section steel pipe; the prefabricated components can be connected with bolts on-site, which has quick constructing speed and high precision. The utility model is suitable for steel structures dwelling houses or office buildings.
Description
Technical field
The utility model relates to a kind of hetermorphiscal column, more particularly, relates to a kind of direct assembly concrete-filled steel tube combined special-shaped column.
Background technology
Encased structures is that fill concrete constitutes in steel pipe, because the effect of contraction of steel pipe, core concrete is in the three dimension stress state during pressurized, improved concrete bearing capacity, and because concrete filling, prevented the too early flexing of steel pipe tube wall, and then reached the effect of 1+1＞2, make it have intensity height, characteristics that anti-seismic performance is good, in addition, concrete filled steel tube also has advantages such as fireproof performance is good, construction is convenient, economic performance is good, and therefore, concrete filled steel tube is used for structural column and has great advantage.
But in dwelling house and office building, usually because excessive pillar cross section makes the building bight salient angle occur, the usable floor area and the furniture that influence the house are arranged.And modern people also more and more pay attention to the house usable floor area more and more higher to interior decoration and environmental requirement, if the bight salient angle problem that can avoid pillar to cause will be a much progress of dwelling house and office building.
Using special-shaped column structure just can avoid the phenomenon of indoor salient angle, and can obtain very big bending rigidity with less cross section, is a kind of pillar form that is suitable for dwelling house, office building.At present using more hetermorphiscal column is the shaped rc columns structure, but concrete is easy to crack, thereby the shearing resistance of post and torsional property are bad, thereby anti-seismic performance exists not enoughly, and construction is complicated, needs the work that installs of a lot of reinforcing bar bindings and template.
In order to solve the problem of indoor-bollard salient angle phenomenon, reinforced concrete post anti-seismic performance deficiency, need seek a kind ofly can guarantee ductility, can bring into play the pillar form of hetermorphiscal column advantage again.
The utility model content
The utility model provides a kind of direct assembly concrete-filled steel tube combined special-shaped column structure.This post is to sew part with dumb-bell shape single rectangular steel pipe is connected, and forms cross sectional shape and be L shaped, T shape or criss-cross hetermorphiscal column, what fluid concrete was made in steel pipe again.
The technical solution of the utility model is as follows:
A kind of direct assembly concrete-filled steel tube combined special-shaped column, this post comprise that steel pipe, dumb-bell shape sew part, stiffener, bolt, concrete; Weld stiffener on the steel pipe tube wall, have bolt hole on the stiffener, dumb-bell shape is sewed part and is comprised two end plates, has on the two end plates and the corresponding bolt hole of stiffener upper bolt hole, and the end plate that dumb-bell shape is sewed part is attached on the stiffener, is connected with single steel pipe bolt; To be connected to form cross sectional shape be L shaped steel pipe combined special-shaped column or sew part by dumb-bell shape and four steel pipes are connected to form steel pipe combined special-shaped column that cross sectional shape is a T shape or sew part by dumb-bell shape five steel pipes are connected to form cross sectional shape is criss-cross steel pipe combined special-shaped column with three steel pipes to sew part by dumb-bell shape, is cast with concrete in steel pipe.
Described dumb-bell shape sew part at the steel pipe two ends respectively the steel pipe dumb-bell shape of welded end plate sew part;
Described dumb-bell shape sew part at the reinforcing bar two ends respectively the reinforcing bar dumb-bell shape of welded end plate sew part;
Described dumb-bell shape sew part at the steel plate two ends respectively the steel plate dumb-bell shape of welded end plate sew part.
The beneficial effects of the utility model are: (1) pillar is wrapped in the body of wall, has avoided indoor bight salient angle to occur, has overcome ordinary rectangular post or the big shortcoming of circular columns sectional dimension; (2) adopt steel core concrete column, improved ductility, overcome the shortcoming that shaped rc columns is easy to crack, antidetonation is bad; (3) spacing of single steel pipe can be adjusted, and realizes bigger bending rigidity easily, and realizes the equistability of two main shafts easily, has saved material; (4) factory-made component, on-the-spot bolt connects, and speed of application is fast, the precision height.Be applicable to steel house or office building.
