Abstract
The utility model relates to an indirect assembled steel pipe concrete combination special-shaped column, which comprises steel pipes, lace pieces, connecting plates, bolts and concrete. The connecting plates are welded onto the steel pipes at first, the laces pieces and the connecting plates are connected with bolts, and a plurality of steel pipes are connected to be the steel pipes combined special-shaped columns with L shaped, T shaped or cross-shaped cross sections, which are completed by pouring 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 beobtained 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 concrete filled steel tube combined special-shaped column, more particularly, relates to a kind of 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 purpose of this utility model provides a kind of indirect assembly concrete-filled steel tube combined special-shaped column.This post is by junction plate, will sew part and be connected with single steel pipe, and connecting many steel pipes, to form cross sectional shapes 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 indirect assembly concrete-filled steel tube combined special-shaped column, this post comprises steel pipe, sews part, junction plate, bolt, concrete, on steel pipe, be welded to connect plate, to sew part is connected with the junction plate bolt, to connect into cross sectional shape be L shaped or four steel pipes are connected into cross sectional shape with three steel pipes is T shape or five steel pipes are connected into cross sectional shape is criss-cross indirect assembled steel tube combined special-shaped column, is cast with concrete in steel pipe;
The described part of sewing is that angle steel is sewed part or steel plate is sewed part;
Described junction plate is steel plate junction plate or T-steel junction plate;
Described steel plate junction plate leaves bolt hole, is erected in the steel pipe sidewall, be welded to connect with steel pipe, angle steel sew part or steel plate sew part leave with the steel plate junction plate on the corresponding bolt hole of bolt hole, the steel plate junction plate with sew the part bolt and be connected;
Described T-steel junction plate is welded on the steel pipe sidewall on one side, Yi Bian have bolt hole, angle steel sew part or steel plate sew part leave with the T-steel junction plate on the corresponding bolt hole of bolt hole, the T-steel junction plate with sew the part bolt and be connected.
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.
