Background technology
Waste concrete block claims regeneration aggregate through aggregate that is broken, that clean and formed after classification; Regeneration aggregate partly or entirely replaces the formulated concrete of the natural aggregates such as sandstone to be called regenerated aggregate concrete, is called for short regeneration concrete.Applying of regeneration concrete is conducive to construction refuse resource, meets environmental protection and sustainable development requirement.The key character of sustainable development is environmental protection and the protection to natural resource.Make full use of regeneration concrete, not only effectively can reduce the quantity of building waste, reduce building waste to the pollution of natural environment, play the effect of protection of the environment; And the regenerated aggregate concrete utilizing regeneration aggregate to configure can also reduce the exploitation to natural aggregate in construction work, reach the object of saving natural sandstone resource.Recycled concrete achieves the recycling to waste concrete, forms new building material product, has significant economy, society and environmental benefit.Therefore; from the angle of environmental protection and utilization of resources; regeneration concrete is considered to ecological ideas concrete; its technical research of Efforts To Develop and application study are useful and necessary; meeting the Mode of Circular of building trade and the low-carbon economic policy requirement of country's promotion, is also one of important measures of the great strategy of human kind sustainable development.
But, owing to adhering to the impact of old mortar in regeneration aggregate, compared with ordinary concrete, regeneration concrete is more prone to occur micro-crack under uniaxial tension effect, and then cause the uniaxial compressive strength of regeneration concrete to be generally less than ordinary concrete, have impact on it and apply.
Utility model content
The technical problems to be solved in the utility model is to provide the regeneration concrete T-steel pipe hetermorphiscal column that a kind of bearing capacity is higher, anti-seismic performance is good.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: regeneration concrete L-type steel pipe hetermorphiscal column, comprise L-type hetermorphiscal column, L-type hetermorphiscal column is welded to form by round steel pipe and two U-shaped steel tanks, round steel pipe is as the corner of L-type hetermorphiscal column, and two U-shaped steel tanks are respectively as two limbs of L-type hetermorphiscal column; General aggregate concrete is built in U-shaped steel tank inside, and regenerated aggregate concrete is built in round steel pipe inside; Be welded with shearing bolt in U-shaped steel tank, the diameter of round steel pipe is greater than the width of U-shaped steel tank.
The diameter of round steel pipe is not less than 1.2 times of U-shaped steel tank width.
U-shaped steel tank is welded by encased steel plate.
The spacing of shearing bolt is not more than the width of U-shaped steel tank.
General aggregate strength grade of concrete is not less than C40, and strength of recycled aggregate concrete grade is not less than C30, and the concrete strength grade of general aggregate is greater than regenerated aggregate concrete.
Regenerated aggregate concrete is made up of new mortar and regeneration aggregate, and regeneration aggregate is made up of original natural aggregate and the old mortar of attachment; General aggregate concrete is made up of new mortar and common natural aggregate.
The steel ratio of L-type steel pipe hetermorphiscal column is 0.04-0.2.
For regenerated aggregate concrete application Problems existing, inventor has devised a kind of regeneration concrete L-type steel pipe hetermorphiscal column, be welded to form by round steel pipe and two U-shaped steel tanks, general aggregate concrete is built in U-shaped steel tank inside, and regenerated aggregate concrete is built in round steel pipe inside; Shearing bolt is welded with in U-shaped steel tank.Owing to adopting large diameter steel tube confinement regeneration concrete in the corner of L-type hetermorphiscal column, improve the stress performance of L-type hetermorphiscal column, improve its anti-torsion ability, and the bearing capacity that improve by the regeneration concrete of steel tube confinement and shock resistance, decrease the suspection of people to regeneration concrete poor performance, be conducive to regeneration concrete applying and construction refuse resource in highrise building.Regeneration concrete L-type steel pipe hetermorphiscal column of the present utility model can be applicable in highrise building, and the region that earthquake intensity is larger, expands the range of application of regeneration concrete.In addition, because encased steel plate and steel pipe can use as template, therefore save template, accelerate speed of application, improve economic benefit.

Detailed description of the invention
As shown in Figures 1 to 3, regeneration concrete L-type steel pipe hetermorphiscal column of the present utility model, comprises L-type hetermorphiscal column, and L-type hetermorphiscal column is welded to form by round steel pipe 2 and two U-shaped steel tanks 1, round steel pipe is as the corner of L-type hetermorphiscal column, and two U-shaped steel tanks are respectively as two limbs of L-type 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 1.2 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, two U-shaped steel tanks again with round steel pipe soldering group l-shaped hetermorphiscal column.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 C40, and strength of recycled aggregate concrete grade is not less than C30, 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 0.04-0.2.
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 L-type hetermorphiscal column, improve the Torsion bearing capacity of L-type 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.
