Abstract
A pitch measuring type slope scale comprises a support leg with one end provided with a tip portion. A first line hammer used for correcting verticality of the support leg is arranged on the support leg, scales are arranged on the surface of the support leg along the vertical direction, the support leg is further hinged with a movable rod used for aiming at points to be measured, a locking nut used for locking and locating the movable rod is further arranged at the hinge position of the movable rod, and a second line hammer is further arranged at the movable end of the movable rod. The pitch measuring type slope scale is simple in structure, reasonable in design, low in construction cost, convenient to carry and capable of being suitable for slope measurement of various complex construction sites.
Description
Technical field
The utility model relates to a kind of span type grade rod.
Background technology
In the engineering construction process, inevitably will use survey instrument, and grade rod is a kind of survey instrument commonly used relatively, at present, those skilled in the art have also designed many grade rods according to practical application.For example: number of patent application is a kind of measurement level of 200920010114.9, vertical, oblique angle grade rod, comprises the chi main body, liquid housing, translucent cover, liquid; The translucent cover angle line is provided with the angle index line on corresponding liquid housing on the perpendicular muscle of chi main body, and corresponding liquid housing place is provided with folding at chi main body lower frame edge, adorns a reflection picture frame in the folding; Catoptron of insert above the reflection picture frame, a vertical miter angle plate is established at the chi main body lower frame edge below the reflection picture frame, and upper ledge is established stay hook; Be provided with the ruler scale mark at chi main body opposite side lower frame edge; Though that this grade rod has is simple in structure, cost is low, reading is directly perceived, advantage easy to use; But because it relies on chi main body to contact with tested surface to realize and measures, when surface of contact was smooth inadequately, the precision of its measurement will be affected.
Summary of the invention
The utility model provides a kind of span type grade rod, and this grade rod is simple in structure, and is reasonable in design, cheap, easy to carry, can adapt to the on-the-spot slope measuring of various complicated construction.
The technical scheme of the utility model is: a kind of span type grade rod; It is characterized in that: comprise supporting leg; Said supporting leg is provided with first plumb bob that is used to correct the supporting leg verticality; Said supporting leg surface is provided with scale along the longitudinal direction, said supporting leg also be hinged with one be used to aim at the measured point motion bar.
The hinged place of above-mentioned motion bar also is provided with the set nut that is used for its locking positioning.
Also be provided with second plumb bob on the movable end of above-mentioned motion bar.
Above-mentioned motion bar is hinged on the central region of supporting leg, and the pin joint of said supporting leg and motion bar is the initial point of scale.
The stiff end of above-mentioned first plumb bob is connected on the scale initial point of supporting leg.
The advantage of the utility model is: this grade rod is reasonable in design, and is simple in structure, cheap, easy to carry, can adapt to the on-the-spot slope measuring of various complicated construction.

Embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and conjunction with figs., elaborates as follows.
Embodiment 1
The span type grade rod of the utility model; Comprise that an end is provided with the supporting leg 1 of tip; Said supporting leg 1 is provided with first plumb bob 2 that is used to correct supporting leg 1 verticality, and said supporting leg 1 surface is provided with scale 3 along the longitudinal direction, said supporting leg 1 also be hinged with one be used to aim at the measured point motion bar 4; The hinged place of said motion bar 4 also is provided with the set nut 5 that is used for its locking positioning; For the ease of regulating, described set nut can adopt knurled nut or wing nut, also is provided with second plumb bob 6 on the movable end of said motion bar 4.Said motion bar 4 is hinged on the central region of supporting leg 1, and said supporting leg 1 is the initial point of scale with the pin joint of motion bar 4, and this scale 3 is unidirectional scale, promptly marks up or down from the scale initial point, marks scale downwards with initial point among Fig. 1 and illustrates.The stiff end of said first plumb bob 2 is connected on the scale initial point of supporting leg.
The span type grade rod of the utility model; Comprise that an end is provided with the supporting leg 1 of tip; Said supporting leg 1 is provided with first plumb bob 2 that is used to correct supporting leg 1 verticality, and said supporting leg 1 surface is provided with scale 3 along the longitudinal direction, said supporting leg 1 also be hinged with one be used to aim at the measured point motion bar 4; The hinged place of said motion bar 4 also is provided with the set nut 5 that is used for its locking positioning; For the ease of regulating, described set nut can adopt knurled nut or wing nut, also is provided with second plumb bob 6 on the movable end of said motion bar 4.Said motion bar 4 is hinged on the central region of supporting leg 1; Said supporting leg 1 is the initial point of scale with the pin joint of motion bar 4; This scale 3 is a centre zero scale, promptly from the scale initial point upwards with mark downwards, the stiff end of said first plumb bob 2 is connected on the scale initial point of supporting leg.
The job step of the utility model: A, setting supporting leg 1 are corrected with 2 pairs of supporting legs 1 of first plumb bob, and are fixed supporting leg 1; B, impact point is set on domatic tested, this impact point be positioned at tested domatic on, and impact point is identical from tested domatic vertical distance from tested domatic vertical distance and motion bar 4 interface points; C, make motion bar 4 run-homes point; D, locking set nut 5 are with fixing motion bar 4; E, supporting leg is set level, made second plumb bob 6 keep vertical state, read the scale value on the supporting leg; F carries out the gradient according to scale value and calculates.
The utility model does not limit to above-mentioned preferred forms, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
