Further, said foundation bolt positioner comprises four blocks of plectanes, four straight-bars and a middle inclined support bar; Said four blocks of plectanes and four straight-bars are formed square; Four blocks of plectanes are distributed on foursquare four angles; Be equipped with on four blocks of plectanes with the tower crane base on corresponding four bolts hole in hole; Four straight-bars are distributed on the four edges, and middle inclined support bar tiltedly is pulled between two plectanes at diagonal angle, all is installed with foundation bolt in each bolt hole.
Further, at least one end of said straight-bar is dismountable to be connected on the plectane, dismountable being connected on the plectane of at least one end of middle inclined support bar.
Further; Four straight-bars are formed by connecting by two short straight rods; One end of a short straight rod is through the mode and the plectane welding of welding, and the other end is connected through bolt with an end of another root short straight rod, and the other end of another root short straight rod is connected with another plectane through bolt.
Further again, middle inclined support bar is formed by connecting two short inclined support bars, connects through bolt between two short inclined support bars, and the other end of two short inclined support bars is connected with two plectanes at diagonal angle respectively through bolt.
The pedestal steel work that is used for tower crane base location and installation of the utility model compared with prior art, has following advantage:
1, the pedestal steel work that is used for tower crane base location and installation has adopted a kind of foundation bolt positioner of being made up of inclined support bar in the middle of four blocks of plectanes, four straight-bars and, and this apparatus structure is light simple, and volume is little, is convenient to transport, and minimizes transport costs.
2, the pedestal steel work that is used for tower crane base location and installation can accurately be located the bolt on the basis, has both guaranteed tower crane base installation in position, can reduce certain transportation mounting cost and labour again, and has realized the disposable smoothing of tower crane base.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done to describe in further detail.
Fig. 1 is the structural representation that is used for the pedestal steel work of tower crane base location and installation, and is as shown in the figure.The pedestal steel work that is used for tower crane base location and installation comprises foundation bolt positioner, foundation bolt 5 and bar frame 6.Bar frame 6 is laid on the basis, and the foundation bolt positioner is arranged on the bar frame 6, and the top of foundation bolt 5 is through on the foundation bolt positioner, and the bottom of foundation bolt 5 and is welded on the bar frame 6 straight down.
Wherein, the foundation bolt positioner comprises inclined support bar 3 in the middle of four blocks of plectanes 1, four straight-bars 2 and, as shown in Figures 2 and 3.Four blocks of plectanes 1 and four straight-bars 2 are formed square, and four blocks of plectanes 1 are distributed on foursquare four angles, and four straight-bars 2 are distributed on the four edges.At least one end of straight-bar 2 is dismountable to be connected on the plectane 1 (in the present embodiment; One end of straight-bar 2 is connected with a plectane through bolt; The other end of straight-bar is fixedly connected with another plectane through the mode of welding), be equipped with on four blocks of plectanes 1 with the tower crane base on corresponding four bolts hole 4 in hole.Middle inclined support bar 3 tiltedly is pulled between two plectanes 1 at diagonal angle, and at least one end of middle inclined support bar 3 is dismountable to be connected (in the present embodiment, the two ends of middle inclined support bar 3 all are connected with plectane through bolt) on the plectane 1.
In the present embodiment, four straight-bars 2 are formed by connecting by two short straight rods, and an end of a short straight rod 21 is through the mode and the plectane welding of welding; The other end is connected through bolt with an end of another root short straight rod 22; The other end of another root short straight rod 22 is connected with another plectane through bolt, like this, when dismounting, only needs bolt is back-outed; Just can straight-bar 2 and plectane 1 be carried out folding, take up room (like Fig. 4 and shown in Figure 5) reduced in folding back.Middle inclined support bar 3 also is formed by connecting two short inclined support bars; Connect through bolt between two short inclined support bars, the other end of two short inclined support bars is connected with two plectanes 1 at diagonal angle respectively through bolt, when dismantling middle inclined support bar 3; Only need the bolt at two ends is back-outed; Will be wherein short inclined support bar Rotate 180 °, just can two short inclined support bars be overlaped (like Fig. 6 and shown in Figure 7), be convenient to put and transport.This pedestal steel work that is used for tower crane base location and installation is foldable positioner, is the field erected practical frock of tower crane bolt.
When using this pedestal steel work that is used for tower crane base location and installation, at first the foundation bolt positioner is removed; Placing of concrete need guarantee that when placing of concrete concrete casting is smooth; Ten six roots of sensation bolts are passed the bolt hole of tower crane base respectively; Behind the tower crane base installation in position, adjust disposable smoothing tower crane base through wedge; Gap below the tower crane base is carried out back-grouting with the mixed earth of rubble and is got final product at last.If bolt has the error of a little when passing the bolt hole of tower crane base, the nut of can screwing at the bolt top is proofreaied and correct with hammer.
