Description
Technical field
The utility model relates to a kind of erection of precast beams position adjusting tools, and in particular to spell to a kind of for precast segment
The three-dimensional adjustment tooling that dress beam positions in erection process.
Background technique
Precast segment spliced girder generallys use bridge machine to set up, and is lifted into using each beam section of day handlebar above bridge machine
Position.Adjust positioning segment position and absolute altitude using the rotating cart of overhead traveling crane and hydraulic cylinder later, when construction slightly shakes, essence
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.Accurate positioning refers to positioning of the segment longitudinally, laterally with vertical three directions.Laterally with the center of route
On the basis of line, that is, central lines of track and beam body center line (back axial line control point) is required to be overlapped；It is longitudinal to be with pinner cross hairs
Benchmark, i.e. support center line and pinner cross hairs are overlapped；Vertically on the basis of back elevation control point elevation.
Utility model content
The utility model provides a kind of three-dimensional adjustment tooling positioned in erection process for precast segment spliced girder,
The three-dimensional adjustment operation of positioning segment beam section when positioning construction for precast segment spliced girder, can accurately adjust positioning section
Section back absolute altitude 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 technology employed by the present utility model 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 above scheme, 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 above scheme, the telescoping mechanism is mechanic jacks.
According to above scheme, the elevating mechanism is hydraulic jack.
Compared with prior art, the utility model has the beneficial effects that can be provided below beam section vertical thrust and
Lateral thrust makes beam section accurately be moved to design position；Beam section can also be made not generate rolling to provide supporting point below beam section simultaneously
It is dynamic, eliminate security risk.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is structural schematic diagram when the utility model direction across bridge is installed；
Fig. 3 is that the utility model indulges bridge to structural schematic diagram when installation.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure
Are as follows: sliding slot 1, telescoping mechanism 2, sliding block 3, elevating mechanism 4, baffle 5, support baseboard 6, gusseted block 7.
The utility model includes horizontally disposed sliding slot 1, is equipped with telescoping mechanism 2 and sliding block 3 in sliding slot 1.Sliding slot 1 wherein one
The end at end is fixedly connected with baffle 5.Telescoping mechanism 2 is mechanic jacks, and the fixing end and baffle 5 of mechanic jacks are fixed to be connected
It connects, 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
Top.The utility model adjusts back absolute altitude using hydraulic jack, and mechanic jacks provide water to the hydraulic jack on sliding slot 1
Flat-pushing power drives beam body mobile, adjusts beam section position.In sliding slot 1 hydraulic jack top/bottom part need to place a monolith tetrafluoroethene plate or
Plastic plate facilitates hydraulic jack 1 sliding along the chute 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 greater 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 use step of the utility model are as follows:
One, coarse adjustment is carried out to positioning segment using bridge machine overhead traveling crane, installation is originally practical near beam bottom pinner after the completion of coarse adjustment
Novel, direction across bridge dispersion four the utility model of installation adjust beam section lateral position to provide lateral pushing power；
Two, adjust beam section middle line: using four direction across bridge place the utility model in mechanic jacks to beam section into
Row laterally adjusts；
Three, beam section mileage is adjusted；Vertical bridge installs four the utility model to dispersion, to provide longitudinal jacking force, such machine
Tool jack pushing tow hydraulic jack carries out beam section longitudinally adjusted；
Four, it adjusts beam section absolute altitude: beam absolute altitude being adjusted using hydraulic jack vertically arranged in the utility model；
Five, after the position of positioning segment is adjusted in place, erection support and anchor and position remove the utility model.
