Abstract
It the utility model is related to a kind of prism bar for the measurement of suspension bridge Datum Strand, including a hexagonal clamp, the hexagonal clamp is bolted by two symmetrical fasteners and formed, each fastener includes 3 sides, one of horizontal edge, the both ends of the horizontal edge connect a hypotenuse with horizontal edge in 120 ° of angles respectively, the lower end of each hypotenuse, which is provided with, to stretch out and the otic placode parallel with horizontal edge, the otic placode is provided with screw, two fasteners are relative to be fastened, and is connected with by the screw on otic placode；The middle part of each horizontal edge connects a prism bar vertical with horizontal edge, and the end of the prism bar is provided with prism.
Description
Technical field
It the utility model is related to a kind of suspension bridge survey tool, and in particular to a kind of to be used for what suspension bridge Datum Strand measured
Prism bar.
Background technology
Before the general Strand Erection of main rope of suspension bridge, benchmark rope need to be measured, by measured data to benchmark rope
Sag, which is adjusted, reaches design attitude.In order to reduce influence of the temperature to main push-towing rope absolute altitude, measurement is typically chosen at dead of night
12 points to 6 points progress, measuring method measure for Trigonometric Leveling by Total Station.Need survey crew each in Datum Strand during gathered data
Prism is set up in characteristic point, because main push-towing rope has away from cat road 1.5m~1.7m distance, people station is needed when setting up prism on ladder
Make prism bar vertical by the way of hand steered, and in total powerstation gathered data, prism bar is held by survey crew and continues at least 2
~3min is in vertical state, waits transferring to subsequent point after the completion of data acquisition and measure.Thus need to expend largely
It is artificial, it is less efficient, and keep vertical using artificial hand steered prism bar, error can occur because of human factor unavoidably, influence to survey
Accuracy of measurement.
The content of the invention
The purpose of this utility model is, there is provided a kind of prism bar for being exclusively used in the measurement of suspension bridge Datum Strand, avoids base
Largely manually expend, save labour turnover during quasi- strand measurement, improve measurement accuracy and operating efficiency.
The technical solution of the utility model is as follows：
A kind of prism bar for the measurement of suspension bridge Datum Strand, it is characterised in that：Including a hexagonal clamp, described six
Side clamp is bolted by two symmetrical fasteners and formed, and each fastener includes 3 sides, one of horizontal edge,
The both ends of the horizontal edge connect a hypotenuse with horizontal edge in 120 ° of angles respectively, the lower end of each hypotenuse be provided with stretch out and with
The parallel otic placode of horizontal edge, the otic placode are provided with screw, and two fasteners are relative to be fastened, and passes through the screw bolt on otic placode
Connection；The middle part of each horizontal edge connects a prism bar vertical with horizontal edge, and the end of the prism bar is provided with prism.
The utility model is simple in construction, easy to use, when being measured for suspension bridge Datum Strand, can be temporarily fixed at benchmark
On strand and keep prism vertical, it is manually hand steered without survey crew, human cost can be greatlyd save, and measurement accuracy is high, speed
Degree is fast, improves operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes a hexagonal clamp 1, the hexagonal clamp 1 is by two symmetrical fastenings
Part, which is bolted, to be formed, and each fastener includes 3 sides, and one of horizontal edge, the both ends of the horizontal edge connect one respectively
Hypotenuse with horizontal edge in 120 ° of angles, the lower end of each hypotenuse, which is provided with, to stretch out and the otic placode 2 parallel with horizontal edge, the otic placode
2 are provided with screw, and two fasteners are relative to be fastened, and is connected by the screw bolt 3 on otic placode；Connect in the middle part of each horizontal edge
A prism bar 4 vertical with horizontal edge is connect, the end of the prism bar 4 is provided with prism 5.Prism is rotatablely connected with prism boom end.
The utility model is easy to quick and precisely adjust prism when it is implemented, level(l)ing bubble 6 can be set on the prism bar
The perpendicularity of bar.
When the utility model makes, hexagonal clamp uses 5 millimeters of steel plate as raw material, by lathe process system
Make.The size of hexagonal clamp is advisable depending on the diameter of Datum Strand with that can clamp Datum Strand.
The utility model is in use, can be temporarily fixed at Datum Strand each needs in the characteristic point that measures.First by six sides
Two fasteners of clamp separate, and are fastened on one on the other on Datum Strand；By the level(l)ing bubble on prism bar, rib is adjusted
Mirror bar is plumbness；Then two fasteners are connected by bolt, it is so manually not hand steered to keep prism bar
Plumbness.Rotating prism makes its be directed at total powerstation direction, gathers the data of prism up and down by total powerstation, two data
Average value is the absolute coordinate at Datum Strand center, you can completes measurement.
Claims (2)
- A kind of 1. prism bar for the measurement of suspension bridge Datum Strand, it is characterised in that：Including a hexagonal clamp, six side Clamp is bolted by two symmetrical fasteners and formed, and each fastener includes 3 sides, one of horizontal edge, institute The both ends for stating horizontal edge connect a hypotenuse with horizontal edge in 120 ° of angles respectively, the lower end of each hypotenuse be provided with stretch out and with horizontal stroke The parallel otic placode in side, the otic placode are provided with screw, and two fasteners are relative to be fastened, and is connected by the screw on otic placode with bolt Connect；The middle part of each horizontal edge connects a prism bar vertical with horizontal edge, and the end of the prism bar is provided with prism.
- 2. the prism bar according to claim 1 for the measurement of suspension bridge Datum Strand, it is characterised in that：The prism bar It is provided with level(l)ing bubble.
