Detailed description of the invention
As shown in Figures 1 to 3, regeneration concrete T-steel pipe hetermorphiscal column of the present utility model, comprises T-shaped hetermorphiscal column, and T-shaped hetermorphiscal column is welded to form by round steel pipe 2 and three U-shaped steel tanks 1, round steel pipe is as the corner of T-shaped hetermorphiscal column, and three U-shaped steel tanks are respectively as three limbs of T-shaped hetermorphiscal column; General aggregate concrete 3 is built in U-shaped steel tank inside, and regenerated aggregate concrete 5 is built in round steel pipe inside; Be welded with shearing bolt 4 in U-shaped steel tank, the diameter of round steel pipe is not less than 1.3 times of U-shaped steel tank width.
Manufacturing process
U-shaped steel tank is welded by encased steel plate, is first welded on steel plate by some row's shearing bolt connectors, and then by steel plate by soldering group synthesis U-shaped steel tank, three U-shaped steel tanks are welded to form T-shaped hetermorphiscal column with round steel pipe again.Build regenerated aggregate concrete in round steel pipe inside, regenerated aggregate concrete is made up of new mortar 6 and regeneration aggregate, and regeneration aggregate is made up of original natural aggregate 7 and the old mortar 8 of attachment.Build general aggregate concrete in U-shaped steel tank inside, general aggregate concrete is made up of new mortar 9 and common natural aggregate 10.Wherein, general aggregate strength grade of concrete is not less than C45, and strength of recycled aggregate concrete grade is not less than C35, and the concrete strength grade of general aggregate is greater than regenerated aggregate concrete.According to " reinforced concrete composite structure design specifications " (JGJ138-2001) regulation: the steel ratio of hetermorphiscal column is within the scope of 0.05-0.2.
Design principle
Steel pipe hetermorphiscal column of the present utility model both can meet requirement for bearing capacity, can improve again intensity and the shock resistance of restrained regeneration concrete.By arranging the larger steel pipe of diameter in the corner of T-shaped hetermorphiscal column, improve the Torsion bearing capacity of T-shaped hetermorphiscal column; Because steel duct builds regenerated aggregate concrete, in a compressed state, improve the intensity of regeneration concrete by the constraint of steel pipe, and then improve the bearing capacity of regeneration concrete, specifically: when axial force increases time, because concrete has certain poisson's ratio, lateral deformation can occur, under lateral deformation suffers restraints situation, the development of concrete microcrack can be restricted, deformation performance also can strengthen, thus improves bearing capacity; Because core concrete suffers restraints, when geological process, the micro-crack of inside concrete is also not easy expansion, thus improves shock resistance.Encased steel plate and natural aggregate concrete are by shearing bolt compact siro spinning technology, and the spacing of shearing bolt is not more than the width of U-shaped steel tank, is conducive to concrete and steel plate collaborative work.
