200.Because rim of a cup basis 200 allows construction error, position is adjustable and is anchored firmly with concrete column 100, large-sized workshop basis
Rim of a cup basis 200 is generally used, the main technique of the lifting construction of concrete column 100 is：Concrete column 100 is hung by crane
Enter rim of a cup basis 200, carried on the back tightly with gad 3, it is then in place according to centre line aligning on post center line and rim of a cup with very heavy item 4, most
It is in the milk afterwards with fine-stone concrete.This method is used till today always, and there is problem mainly has：
First, concrete column 100 is more small than rim of a cup basis 200, and correction is difficult, and timing loosens gad 3 repeatedly, with thousand
The outer rim of concrete column 100 is pushed up in 4 sides of jin top, and concrete column 100 easily topples, the easy losing fangle in root of concrete column 100, influence
Stress and attractive in appearance；
Second, concrete column 100 is simply put into rim of a cup basis 200 by prior art, secondary centering, in place and raising mark
Height is required for artificial adjustment, and not only the time is long, also easily destroys concrete column when clamping concrete column 100 is moved with jack 4
100, i.e. not only benefit is low for existing concrete column lifting installation method, is also unfavorable for finished product protection.
The content of the invention
The present invention is made to solve above-mentioned technical problem present in prior art, and its object is to provide one kind
Do not need side fore-set, avoid the modification of post root, quick concrete column lifting installation method in place.
To achieve these goals, the present invention provides a kind of concrete column lifting installation method, including：It is pre- in concrete column
During system, at least four positioning pipes are buried in post root bottom part, wherein, arbitrary neighborhood Liang Gen positioning pipes bottom center is on coagulation
Earth pillar bottom center line is symmetrical；After prefabricated completion concrete column, the center line of every positioning pipe is ejected simultaneously in concrete column bottom
Cylinder cross hairs is marked on the vertical axis of at least two sides in addition to bottom surface and top surface in concrete column；Rim of a cup basis is looked for
It is flat；At least four positioning holes are drilled with rim of a cup bottom of foundation position corresponding relative to concrete column positioning pipe, wherein, it is described fixed
The centre-to-centre spacing of position hole to the rim of a cup bottom of foundation is equal with the centre-to-centre spacing of positioning pipe bottom center to the concrete column bottom center；
The rim of a cup bottom of foundation the positioning hole reinforcement planting as positioning bar, positioning bar one end leaks outside in the rim of a cup bottom of foundation, another
End insertion the rim of a cup bottom of foundation below, and positioning bar top surface using cross hairs mark positioning bar center, wherein, positioning bar
Diameter is less than the diameter of positioning pipe；In the basic top surface subscript of the corresponding rim of a cup in concrete column side with being labeled with cylinder cross hairs
Go out post centering insertion control point, i.e. the midpoint on the side close to side described in above-mentioned concrete column is marked on the basic top surface of rim of a cup；
Concrete column is sling, transfer to the post centering control point of the basic top surface of the crosspoint of its side cylinder cross hairs and rim of a cup with
In same level, adjust crosspoint and the post centering control point of cylinder cross hairs with this sideways vertical same axis；
Continue to transfer concrete column, reach above positioning bar, the cross at the top of the center line and positioning bar of concrete column bottom positioning pipe
Line is overlapped, and positioning bar is inserted in positioning pipe, and post is in place, and then grouting is fixed.
Above-mentioned concrete column lifts installation method, by the positioning that positioning pipe and the rim of a cup bottom of foundation are buried in concrete column
Muscle fixing concrete post is interior to rim of a cup basis, and utilizes the post centering insertion point on the basic top surface of rim of a cup and concrete column corresponding surface
On cylinder cross hairs crosspoint, adjust concrete column perpendicularity, utilize the cross hairs on rim of a cup bottom of foundation positioning bar
Overlapped with positioning pipe center line, adjust the levelness of concrete column so that concrete column need not use jack and gad
The adjustment of the perpendicularity and levelness of concrete column is completed, therefore post root will not deform, and can be quickly by concrete column
Lifting is interior to rim of a cup basis in place.
