Description

The three-dimensional adjustment tooling positioned in erection process for precast segment spliced girder
Technical field
The present invention relates to a kind of erection of precast beams position adjusting tools, and in particular to being used for precast segment spliced girder to a kind of The three-dimensional adjustment tooling positioned in erection process.
Background technology
Precast segment spliced girder generally use bridge machine is set up, and is lifted into using each beam section of day handlebar above bridge machine Position.Positioning segment position and absolute altitude is adjusted using the rotating cart of overhead traveling crane and hydraulic cylinder, when construction slightly shakes, essence later Deficiency is adjusted, can not be accurately positioned.
Positioning segment (first segment) be it is whole across starting point, directly control it is whole across it is linear, therefore when carrying out assembled, it is necessary to It is accurately positioned first segment.It is accurately positioned the positioning for referring to segment longitudinally, laterally with vertical three directions.Laterally with the center of circuit On the basis of line, that is, central lines of track and beam body center line (back axial line control point) is required to overlap;It is longitudinal to be with pinner cross hairs Benchmark, i.e. bearing center line and pinner cross hairs overlap;Vertically on the basis of back elevation control point elevation.
Invention content
The present invention provides a kind of three-dimensional adjustment toolings positioned in erection process for precast segment spliced girder, are used for The three-dimensional adjustment operation of the positioning segment of precast segment spliced girder beam section when positioning construction, can accurately adjust positioning beam sections Top mark height and beam section mileage position greatly improve construction rate of the positioning segment of beam sections in erection process.
In order to solve the above technical problems, the technical solution adopted in the present invention is:
A kind of three-dimensional adjustment tooling positioned in erection process for precast segment spliced girder, including horizontally disposed cunning Slot, sliding slot is interior to be equipped with telescoping mechanism and sliding block;The end of sliding slot wherein one end is fixedly connected with baffle;One end of telescoping mechanism with Baffle is fixedly connected, and the other end is connect with sliding block;Vertically arranged elevating mechanism is connected at the top of sliding block.
According to said program, the bottom of side of the baffle far from sliding slot is connected with horizontally disposed support baseboard, gear Gusseted block is fixedly connected between plate and support baseboard.
According to said program, the telescoping mechanism is mechanic jacks.
According to said program, the elevating mechanism is hydraulic jack.
Compared with prior art, the beneficial effects of the invention are as follows:Vertical thrust and transverse direction can be provided below beam section Thrust makes beam section accurately be moved to design position;There is provided supporting point simultaneously or below beam section makes beam section not generate shaking, disappears In addition to security risk.
Description of the drawings
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is structural schematic diagram when direction across bridge of the present invention is installed;
Fig. 3 is that the present invention indulges bridge to structural schematic diagram when installation.
Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings, each label is interpreted as in figure:It is sliding Slot 1, telescoping mechanism 2, sliding block 3, elevating mechanism 4, baffle 5, support baseboard 6, gusseted block 7.
The present invention includes horizontally disposed sliding slot 1, and telescoping mechanism 2 and sliding block 3 are equipped in sliding slot 1.The wherein one end of sliding slot 1 End is fixedly connected with baffle 5.Telescoping mechanism 2 is mechanic jacks, and the fixing end of mechanic jacks is fixedly connected with baffle 5, Movable end is connect with sliding block 3.The top of sliding block 3 is connected with vertically arranged elevating mechanism 4, and elevating mechanism 4 is hydraulic jack. The present invention adjusts back absolute altitude using hydraulic jack, and mechanic jacks provide horizontal thrust to the hydraulic jack on sliding slot 1 Drive beam body movement, adjustment beam section position.Hydraulic jack top/bottom part need to place a monoblock tetrafluoroethene plate or plastic plate in sliding slot 1 Hydraulic jack top edge sliding slot 1 is facilitated to slide as sliding block 3.Sliding slot 1 is placed directly in above pier top, close to bearing pad stone position. Impurity must not be arranged at 1 bottom of sliding slot, it is ensured that sliding slot 1 is more than the frictional force of hydraulic jack and sliding slot 1 with pier top frictional force.
The bottom of side of the baffle 5 far from sliding slot 1 is connected with horizontally disposed support baseboard 6, baffle 5 and support baseboard 6 Between be fixedly connected with gusseted block 7.Baffle 5, support baseboard 6 and gusseted block 7 form wedge shaped support structure, wedge shape branch Support structure can play the role of limited support to mechanic jacks, and good support force can be provided for mechanic jacks;And The structural strength that entire sliding slot 1 can be improved, promotes the stability of entire tooling.
The present invention use step be:
One, coarse adjustment is carried out to positioning segment using bridge machine overhead traveling crane, the present invention is installed near beam bottom pinner after the completion of coarse adjustment, Direction across bridge dispersion four present invention of installation are to provide lateral pushing power, adjustment beam section lateral position;
Two, beam section center line is adjusted:Mechanic jacks in the present invention placed using four direction across bridge carry out beam section horizontal To adjustment;
Three, beam section mileage is adjusted;Vertical bridge installs four present invention to dispersion, to provide longitudinal jacking force, so mechanical thousand Jin top pushing tow hydraulic jack carries out beam section longitudinally adjusted;
Four, beam section absolute altitude is adjusted:Beam absolute altitude is adjusted using hydraulic jack vertically arranged in the present invention;
Five, after the position of positioning segment is adjusted in place, erection support and anchor and position remove the present invention.
