Abstract
The invention relates to steel tube-I-beam combination steel tube concrete special-shaped columns, which comprises steel tubes, I-beams and concrete poured inside the special-shaped columns. The steel tubes and the I-beams are welded together to compose the special-shaped columns with different sections. The whole sections are separated through the steel tubes and the I-beams, then the concrete is filled in separation spaces of the steel tubes and the I-beams, the steel tubes can be made by welding or rolling, and the I-beams can be made by welding or rolling. The steel tube-I-beam combination steel tube concrete special-shaped columns have the advantages that inside corner steel tube walls and I-beam flange steel plates are communicated with each other so as to overcome the defect that force delivery of inside corner portions of other steel tube concrete special-shaped columns is unclear, and whole working capacity of steel tube concrete special-shaped columns is improved. The steel tubes are placed at the edges and at corner portions of the sections so as to improve restrain capacity of the special-shaped columns. The steel tubes and the I-beams separate the concrete of the special-shaped columns, width-to-thickness ratio of the steel plates is reduced, bearing capacity and shock-resistance are improved, production and assembly of the special-shaped columns are modularized, and simultaneously construction speed is fast.
Description
Technical field
The present invention is specifically related to a kind of steel pipe-i iron combined steel pipe concrete profiled pile and preparation method thereof.
Background technology
Concrete filled steel tube is a fill concrete and forming in the steel pipe, and steel pipe and core concrete thereof can bear the structural element of external load effect jointly.Because the supporting role of fill concrete can prevent that the steel pipe tube wall from too early flexing taking place in advance, steel pipe is to the effect of contraction of core concrete simultaneously, thereby makes concrete filled steel tube have very high bearing capacity; Advantages such as concrete filled steel tube also has plasticity and good toughness simultaneously, and shock resistance is strong.Therefore, concrete filled steel tube has broad application prospects.
Avoid the outstanding influence of room corner post corner angle for satisfying building requirements in the architectural design to sighting within doors and taking up room; Improve the flexibility that premises furniture is arranged; Post jamb and infilled wall have obtained using widely with thick shaped rc columns structure; But concrete is easy to crack, thereby the shearing resistance of post and antitorque bearing capacity are relatively poor, so shock resistance is not enough.Also have at present some scholars to propose the section form of multiple steel pipe concrete profiled pile, but when flakiness ratio is big, exist steel pipe not strong to the concrete restriction ability, easily too early flexing reduces bearing of component.
Be to solve the shortcoming of shaped rc columns to antidetonation ability and steel core concrete column, it is good to seek a kind of ductility, the hetermorphiscal column that bearing capacity is high.
Summary of the invention
The present invention has overcome the deficiency of the hetermorphiscal column of existing concrete filled steel tube; Particularly overcome in the bigger concrete filled steel tube of flakiness ratio steel pipe to the deficiency of core concrete restriction ability; Thereby improved bearing of component and ductility, realized the production of steel pipe concrete profiled pile, the modularization of assembling simultaneously.Construction is made, and designs also simple relatively.
The present invention is a kind of steel pipe-i iron combined steel pipe concrete profiled pile, comprises steel pipe, i iron and builds the concrete composition in it; Steel pipe and i iron weld together the hetermorphiscal column of forming different cross section.Whole cross section is separated by steel pipe and i iron, again fill concrete in the space of steel pipe and i iron separation.
Described steel pipe can be to weld also rolling forming, and described i iron can be to weld also rolling forming.
The preparation method of said steel pipe-i iron combined steel pipe concrete profiled pile is characterized in that:
(1), prefabrication steel pipe and i iron:
Make steel pipe: steel pipe adopts by being welded or rolling forming; I iron adopts by being welded or rolling forming;
(2), field Welding steel pipe-i iron combined steel pipe concrete profiled pile:
After member was transported to the scene, the welding H-bar respectively on the adjacent both sides of steel pipe was welded in two steel pipes the other end of two i iron again, and it is L shaped steel pipe-i iron combined steel pipe concrete profiled pile that three steel pipes and two i iron are connected into cross sectional shape;
After the fixed in place,, form L shaped steel pipe-i iron combined steel pipe concrete profiled pile in concreting maintenance in the steel pipe and the i iron compartment;
(3), adopt identical method of attachment, four steel pipes and three i iron are welded, the concreting maintenance forms teeprofile-i iron combined steel pipe concrete profiled pile;
(4), adopt identical method of attachment, five steel pipes and four i iron are welded, the concreting maintenance forms ten shapes steel pipe-i iron combined steel pipe concrete profiled pile;
The invention has the advantages that:
(1) inner corner trim place steel pipe walls and i iron edge of a wing steel plate connect each other that to have overcome other steel pipe concrete profiled pile inner corner trim portion power transmissions unclear, have strengthened the overall operation ability of steel pipe concrete profiled pile;
(2) steel pipe is placed on the edge and the bight in cross section, produces stronger effect of contraction, has improved the bearing capacity and the shock resistance of hetermorphiscal column;
(3) steel pipe and i iron are separated the transmission to adjacent part that has prevented local distress in concrete with the cross section of hetermorphiscal column; Can effectively increase steel pipe to concrete restriction ability; Thereby, improve the bearing capacity and the ductility of hetermorphiscal column from minute performance steel and a concrete advantage separately;
(4) space of steel pipe and i iron separation is separate directly stressed, reduces the flakiness ratio of hetermorphiscal column cross section steel plate, prevents the too early flexing of steel pipe.
