contrary work in the fixing device for installing of steel pipe column after above-mentioned improvement, is provided with and can realizes vertical jack and the jack support of longitudinally controlling, and vertical jack is supported on articulated beam outer end.

contrary work in the fixing device for installing of steel pipe column after above-mentioned improvement, described articulated beam links together after installation has been located with firm bracing frame upper strata, if articulated beam and just bracing frame upper strata have gap to connect by adding junction plate.

compared with prior art, the utility model is useful in the reverse construction in civil engineering, be particularly suitable for the reverse construction in the super dark engineering of super large, by firm bracing frame, lead and tie-beam in the utility model, can realize and do to contrary that steel pipe column is disposable puts into hole stake, and it is just located and is fixed, then finely tune and adjust the contrary along slope coordinate of making steel pipe column by the contrary steel pipe column coordinate of doing of longitudinal jack pair, laterally jack adjustment is against making steel pipe column verticality.The utility model simple in structure firm, easy to operate, can save the construction period, save construction costs.

Accompanying drawing explanation

fig. 1 is the utility model structural representation;

contrary steel pipe column, 2-steel bracing frame, 3-articulated beam, 4-otic placode, 5-lead, 6-otic placode, the horizontal jack of 7-, the vertical jack of 8-, the support of 9-jack, 10-Prefabricated reinforced concrete cushion cap, 11-clamped beam, 12-reinforcing cage, 13-positioning beam, the 14-pile foundation steel casing done of 1-.

The specific embodiment

below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.

a kind ofly improve the rear contrary fixing device for installing of making steel pipe column, comprise contrary do steel pipe column 1 and steel bracing frame 2, at steel bracing frame 1 top, be provided with articulated beam 3, the inner of articulated beam 3 is connected with lead 5 upper ends by otic placode 4, and lead 5 lower ends are done steel pipe column 1 upper end and are connected with contrary by otic placode 6.

wherein just bracing frame 2 is clad steel frame construction, and just bracing frame 2 lower floors are provided with and can realize horizontal jack 7.

wherein be provided with and can realize vertical jack 8 and the jack support 9 of longitudinally controlling, and vertical jack 8 is supported on articulated beam 2 outer ends.

wherein articulated beam 2 links together after installation has been located with firm bracing frame 2 upper stratas, if articulated beam 2 has gap to connect by adding junction plate with firm bracing frame 2 upper stratas.

after described this improvement, the contrary fixing device for installing Specific construction step of making steel pipe column is for as follows:

1, the pile foundation completing in construction around original ground is made Prefabricated reinforced concrete cushion cap, Prefabricated reinforced concrete cushion cap surface is provided with the embedded hole that can be connected with steel bracing frame, wherein, by reinforcing bar or section bar, Prefabricated reinforced concrete cushion cap and ground are coupled together, steel bracing frame is placed on prefabricated cushion cap, and is fixed as one by embedded hole.

2, reinforcing bar cage hoisting is placed on to the bottom, stake hole of having constructed.

3, firm bracing frame is placed on Prefabricated reinforced concrete cushion cap, just the connecting hole under bracing frame is corresponding with embedded hole, and is provided with supporting very heavy nail support and vertical jack.

4, steel pipe column and measure steel pipe column are coupled together by otic placode as an integral body and adopt the ground lifting method that directly tilts to lift by crane, steel pipe column and measure steel pipe column support internal diameter by steel and slowly put into pile foundation.
