Abstract
The utility model discloses an embedded bolt positioning device for a tower crane foundation, which includes four steel sheets and lacing bars for fixedly connecting the four steel sheets, wherein the four steel sheets correspond to to-be-mounted bottom part fixing plates of a tower crane foundation section in position; four through holes are arranged on every steel sheet, and the through holes correspond to the mounting holes on the bottom part fixing plates of the tower crane foundation section in position; the lacing bars include a diagonal lacing bar, a transverse lacing bar and a vertical lacing bar; the two ends of the diagonal lacing bar are welded to the two diagonal steel sheets of the four steel sheets respectively; the two ends of the transverse lacing bar are welded to the two transverse-corresponding steel sheets respectively; and the two ends of the vertical lacing bar are welded to the two vertical-corresponding steel sheets respectively. The utility model has the advantages that the embedded bolt positioning device for the tower crane foundation can greatly improve the precision of the embedded bolts, and reduce the labor intensity of constructors.
Description
Technical field
The utility model has related to a kind of pillar crane installation auxiliary device, particularly a kind of pillar crane pre-embedded bolt positioner.
Background technology
Pillar crane is the indispensable lifting appliance of building unit in recent years, because of pillar crane install improper because of the accident that rises also be frequent appearance.Wherein the installation accuracy of the pre-embedded bolt of tower crane foundation plays a decisive role to the installation quality of pillar crane.Yet the installation accuracy of pre-embedded bolt is difficult to control, for example existing QTZ160 pillar crane, each angle of base section is fixed by four pre-embedded bolts, the pre-embedded bolt position must be accurate, otherwise influence installation accuracy, can't install even, not only influence the pillar crane installation progress, also can directly influence the pillar crane installation quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of tower crane foundation pre-embedded bolt positioner, it can accurately locate the tower crane foundation pre-embedded bolt fast, improve pre-embedded bolt installation accuracy and pillar crane installation quality, reduce constructor's labour intensity, stop the improper potential safety hazard of bringing to be installed because of pillar crane.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of tower crane foundation pre-embedded bolt positioner comprises four block plates and is used for fixing the lacing wire that is connected described four block plates; Position relation between described four block plates is corresponding with the position that tower crane foundation to be installed saves bottom fixed board; Described every block plate is provided with four through holes, and the position of through hole is corresponding with the position of mounting hole on the tower crane foundation joint bottom fixed board; Described lacing wire comprises diagonal brace, laterally lacing wire and vertical lacing wire; Described diagonal brace two ends are welded on respectively on two block plates that are in four block plates angular dependence; Described horizontal lacing wire two ends are welded on respectively on two block plates of horizontal correspondence; Described vertical lacing wire two ends are welded on respectively on two block plates of vertical correspondence.
The diameter of described through hole is identical with the installing hole diameter that tower crane foundation to be installed saves on the bottom fixed board.
Adopt the beneficial effect that technique scheme produced to be: four block plates of tower crane foundation pre-embedded bolt positioner are the diagonal angle setting, every block plate is respectively at the fixed head correspondence of tower crane foundation joint bottom, and the outline of steel plate is slightly larger than fixed head, also be provided with on four block plates with fixed head on the corresponding through hole of installing hole, in work progress, control the levelness of the height and the concrete surface of pre-embedded bolt by controlling the four block plates discrepancy in elevation each other, control pre-embedded bolt position each other by the relative position between the through hole on four block plates, make that the position relation between the pre-embedded bolt is more accurate, improve pre-buried efficient on the one hand, reduce constructor's labour intensity, improve the pillar crane installation quality on the other hand, avoid potential safety hazard.

The specific embodiment
A kind of tower crane foundation pre-embedded bolt positioner as shown in Figure 1 comprises four block plate 2-1 and is used for fixing the lacing wire that is connected described four block plate 2-1; Position relation between the described four block plate 2-1 is corresponding with the position that tower crane foundation to be installed saves bottom fixed board; Described every block plate 2-1 is provided with four through hole 2-2, and the position of through hole 2-2 is corresponding with the position of mounting hole on the tower crane foundation joint bottom fixed board; Described lacing wire comprises diagonal brace 2-4, horizontal lacing wire 2-5 and vertical lacing wire 2-3; Described diagonal brace 2-4 two ends are welded on respectively on the two block plate 2-1 that are among the four block plate 2-1 angular dependence; Described horizontal lacing wire 2-5 two ends are welded on respectively on the two block plate 2-1 of horizontal correspondence; Described vertical lacing wire 2-4 two ends are welded on respectively on the two block plate 2-1 of vertical correspondence.
The diameter of described through hole 2-2 is identical with the installing hole diameter that tower crane foundation to be installed saves on the bottom fixed board.
(participate in accompanying drawing 2) in the concrete work progress, at first pillar crane pre-embedded bolt positioner is placed in the good reinforcement foundation top of colligation, determine the position of four block plates according to designing requirement, then setscrew nut is screwed on the pre-embedded bolt, and the pre-embedded bolt end of thread passed through hole from steel plate below, determine that by adjusting setscrew nut pre-embedded bolt passes the length of steel plate, all the pre-embedded bolt crotch places that the 3rd step will adjust and the vertical muscle spot welding of tower crane foundation, and then adjustment setscrew nut, make the four block plate end face discrepancy in elevation less than 1%, realize the accurate location of pre-embedded bolt, last concreting, and the leveling concrete end face is so far finished the pre-buried of tower crane foundation pre-embedded bolt to the positioning bolt end face; Treat that concrete reaches after the intensity of installation requirement, pull down tower crane foundation pre-embedded bolt positioner and can carry out the installation of tower crane foundation joint, improve installation effectiveness and installation accuracy greatly, can also reduce constructor's labour intensity, the tower crane foundation pre-embedded bolt positioner of pulling down in addition can also have enough to meet the need use.
