Preferably, the medial surface of described deflector apron 3 the most gradually tilts to the outside of described positioning framework 1,
Thus realize the effect of guide posts lifting location.It is set to medial surface the most gradually to location by being directed to baffle plate
The version that the outside of framework tilts, it is possible to effectively the default specified location of prefabricated stand column lifting to cushion cap is led
To the effect with location so that installation process is the most convenient and smooth and easy, prevent hoisting process from occurring skew being installed or installing
Position the generation of inaccurate phenomenon.
This utility model also provides for the locating mounting method of a kind of prefabricated stand column horizontal level, and it uses aforesaid prefabricated vertical
The horizontal positioning device of post, positions and fixes prefabricated stand column according to default horizontal level and is installed on cushion cap.By this reality
Locating mounting method with novel prefabricated stand column horizontal device, it is possible to be first positioned and secured on cushion cap by positioning framework is pre-
Column processed needs the horizontal position of location, then the central hollow position by prefabricated stand column lifting to the inside of positioning framework,
Then it is connected fixing between prefabricated stand column with cushion cap, thus realizes the most accurate location to prefabricated stand column horizontal level,
Being accurately positioned of prefabricated stand column position in the horizontal direction can be effectively realized so that prefabricated stand column is pre-when splicing with bottom cushion cap
The positioning precision of column horizontal level processed is high, it is simple, convenient to control.
In such scheme, first pass through shaft centerline measurement and determine reserved steel bar position in cushion cap, control Two bors d's oeuveres posting with this
Rack position, is i.e. determined the control outer edge of column bottom surface, then column lifting is guided to positioner by deflector apron, from
And the level to prefabricated stand column that realizes is to being accurately positioned.
Preferably, step one: city's roads (first, in civil engineering surveying, has zonal benchmark on cushion cap
Point, datum mark is measured and is obtained, the most precisely by precision instrument measurement by specialty unit；Go between according to datum mark, by coordinate bit
Put by measure axis to target proximity to be measured, determine the datum mark coordinate of target proximity to be measured, then treat according to this coordinate
Survey target measures.Setting-out belongs to general measure means in civil engineering.), determine reserved steel bar position, and reserved steel is set
Muscle；
Step 2: install and fix between reserved steel bar corresponding for the bearing of positioning framework；
Step 3: the ring flange of Two bors d's oeuveres bindiny mechanism is interfixed with bolt respectively so that described positioning framework is formed
Guan Bi framework；
Step 4: by prefabricated stand column lifting and put in positioner along deflector apron, complete the essence to its horizontal level
Determine position.
This is the concrete operation step of locating mounting method and the operational approach of prefabricated stand column horizontal level, is effectively realized
Prefabricated stand column horizontal direction position is installed on accurate as to position the default specified location of bottom cushion cap.
Introduce operation principle of the present utility model and preferred embodiment below in conjunction with the accompanying drawings:
The hugest in view of precast bridge column component volume weight, during on-site consolidation, its horizontal direction assembly is fixed
The more difficult control in position.The utility model proposes a kind of prefabricated stand column level to accurate positioning device, for lifting at prefabricated stand column
During, accurately control to ensure its precision conformance with standard requirement to location to its level.
Referring to figs. 1 to shown in Fig. 4, a kind of prefabricated stand column level is to accurate positioning device, including Two bors d's oeuveres positioning framework 1, with
The bearing 2 that bottom cushion cap connects, plays guide posts and positions the deflector apron 3 transferred, and be connected by Two bors d's oeuveres positioning framework is double
Join connection mechanism 4, and the reserved steel bar hole 5 on bearing.
During prefabricated stand column assembly, first having to position reserved steel bar position in cushion cap, its principle is to pass through
Datum mark, surveying setting-out determine prefabricated stand column horizontal level in cushion cap (after measured target has been disposed about datum mark,
Size according to drawing upper pillar stand position and coordinate, from datum mark lead-in wire so that it is determined that column horizontal level), pass through reserved steel bar
Transmitting, this process belongs to conventional method, does not repeats in this.
During mounting and positioning device, first Two bors d's oeuveres positioning framework 1 is fixed on reserved steel bar by the preformed hole of bearing 25 and holds
On platform, then by the ring flange of Two bors d's oeuveres bindiny mechanism upper 4, Two bors d's oeuveres positioning framework bolt is tightened together, form Guan Bi
Framework.
During the prefabricated stand column of location, first prefabricated stand column is sling, guided the horizontal position of correction prefabricated stand column by deflector apron 3
Put, prefabricated stand column is put in positioner completely, complete the level of prefabricated stand column to location, finally, remove Two bors d's oeuveres and connect machine
Bolt on structure 4 and the retainer ring on bearing 2, depart from positioner dismounting.
Beneficial effect: during can be to prefabricated stand column at the scene assembly, carries out accurate horizontal direction location, solves prefabricated
Splicing precision problem rambunctious between column (or pier stud) and cushion cap, is effectively ensured the scene of precast bridge column (pier stud)
Installation quality.
Those skilled in the art is it is easily understood that on the premise of not conflicting, above-mentioned each advantageous manner can be free
Ground combination, superposition.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.The above is only preferred implementation of the present utility model, it is noted that for the art
For those of ordinary skill, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification,
These improve and modification also should be regarded as protection domain of the present utility model.
