Description
Technical field
the present invention relates to bearing calibration and the device of steel beam column verticality in the construction of a kind of stand column pile, belong to construction foundation working technical field.
Background technology
in the fast development process of urban construction; the Application and Development of the underground spaces such as building basement, underground store and subway station gets more and more; for the consideration of the factors such as environmental protection, construction period, roading; many employings stand column pile is constructed; stand column pile takes full advantage of outer wall of basement as to go along with sb. to guard him and structural beam slab doubles as support; there is the advantages such as rigidity is large, Bit andits control ability is strong, field course layout is convenient; but at present in stand column pile work progress, how accurately, the verticality problem that controls stand column pile is efficiently the technical barrier needing to solve.
the verticality of current control stand column pile mainly contains three kinds of solutions, first air bag vertical adjustment method, and to be that four limits are each bottom steel beam column fix an air bag to specific practice, and air bag transfers to below ground with steel beam column, and is fixed in stressed good soil layer.By realizing the control of verticality to different bladder inflation/deflation.The subject matter that the method exists is that air bag has certain stroke, and adjusting range is less, requires higher to the verticality of stake holes.In addition, owing to adopting canvas air bag, in actual use, length is broken by hook and cannot construct, and air bag is also often embedded in concrete and is difficult to reclaim.
it two is mechanical vertical adjustment methods: the method is that the screw rod having a difference in height by four direction more than ground regulates, and screw rod heads on steel beam column and produces turning moment and realize degree control.The subject matter that the method exists is the vertical adjustment that can only be used for the larger steel beam column of rigidity (steel pipe bearing post etc.), if steel beam column rigidity less (as lattice column etc.), the flexural deformation applying lattice column during moment of torsion on top is excessive, is unfavorable for the vertical adjustment of lattice column.The party's ratio juris is the long limit utilizing the minor face basseted to control pile body, and error is comparatively large, and floor space is large.
it three is pilot sleeve vertical adjustment methods, and the method is converted into pilot sleeve correcting a steel beam column.The vertical adjustment of pilot sleeve can adopt air-bag method and mechanical vertical adjustment method.Subject-oriented sleeve vertical adjustment terminates and after fixing, inserts steel beam column, arrange the insertion that pulley is beneficial to support column, then build stand column pile concrete, until concrete extracts pilot sleeve after fixing steel beam column in pilot sleeve in the middle of pilot sleeve.The subject matter that the method exists is: because pilot sleeve is outside steel beam column, and aperture certainly will be made to become large.And sleeve self is without vertical adjustment function, need carry out vertical adjustment by air-bag method or mechanical vertical adjustment method, vertical error can be accumulated.
in sum, all there is a kind of problem in several vertical adjustment methods conventional at present, all undesirable to the degree control precision of steel beam column.
