Abstract
The utility model provides a gradient rulers, includes the main scale, and at least one side system of main scale is scaled, and zero graduation end axis position is articulated with the one end of down tube on the main scale, and the other end of down tube is articulated with the bracing piece, is equipped with the external screw thread on the bracing piece, and the nut passes through the screw thread and installs on the bracing piece. The utility model relates to a gradient rulers according to triangle -shaped similarity theorem, through adjusting, makes main scale, down tube and bracing piece constitution right angle triangle -shaped. Read out reading and nut lower extreme to the pitch number of down tube with the articulated department of bracing piece on the scale again, then simply the slope of surveying size can be obtained in calculation, easy operation is convenient. Again because the device articulated the forming that be each part, simple structure, conveniently carry, with low costs.
Description
Technical field
The utility model relates to a kind of measurement of the level instrument, is specifically related to a kind of grade rod.
Background technology
Current measurement of the level instrument mainly contains levelling pole and spirit-leveling instrument, and existing levelling pole can measure building sides whether level or vertically, but if desired measures the slope requirement whether tested surface reach theoretical, then need to utilize spirit-leveling instrument or other more complicated instruments.And spirit-leveling instrument carries trouble, and cost is higher, not easy to operate.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of grade rod, can not only measure the slope requirement whether tested surface reaches theoretical, and structure simple, be convenient for carrying, cost is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of grade rod, comprise main scale, at least side of main scale is shaped with scale, and on main scale, one end of zero mark end and brace is hinged, and the other end and the support bar of brace are hinged, and support bar is provided with external thread, and nut is arranged on support bar by screw thread.
Described main scale is socketed to form by multiple secondary chi, is mutually slidably connected between secondary chi.
Described brace is socketed to form by multiple pole, is mutually slidably connected between pole.
Described main scale transversely with is longitudinally respectively equipped with bubbler tube, and in bubbler tube, envelope has liquid and bubble.
Described main scale both sides are all shaped with scale.
Described support bar is provided with the mark number of mark pitch number.
A kind of grade rod of the utility model, technique effect is as follows:
1), when using, brace is affixed on inclined-plane and places, main scale is placed on the nut that is threaded with support bar.By setting nut, and observe the bubble in bubbler tube, make main scale terminal level.Thus form the right-angle triangle be made up of main scale, brace and support bar.By reading reading on scale and the nut lower end pitch number to brace and support bar hinged place, then surveyed gradient size can be obtained according to the calculating of triangle correspondence theorem.Then compare with design grade, the slope requirement whether tested surface reaches theoretical can be determined.
2), because main scale and brace are Collapsible structure, according to actual needs, by the cooperation of main scale, brace and support bar, both can measure the segment gradient, also can measure the mean inclination on longer slope.
3), because main scale is all connected in hinged mode with brace and support bar, therefore, when carrying, this device can be carried out folding placement, being convenient for carrying.
4), compared with spirit-leveling instrument, structure is simple, easy to operate, cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is described further:
Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
In figure: main scale 1, scale 2, brace 3, support bar 4, nut 5, secondary chi 6, pole 7, bubbler tube 8.
Embodiment
As shown in figs. 1-2, a kind of grade rod, comprises main scale 1, the at least side of main scale 1 is shaped with scale 2, and on main scale 1, one end of zero mark end and brace 3 is hinged, and the other end and the support bar 4 of brace 3 are hinged, support bar 4 is provided with external thread, and nut 5 is arranged on support bar 4 by screw thread.Main scale 1 can be placed on nut 5, and by setting nut 5, can form the right-angle triangle be made up of main scale 1, brace 3 and support bar 4.
Described main scale 1 is socketed to form by multiple secondary chi 6, is mutually slidably connected between secondary chi 6; Described brace 3 is socketed to form by multiple pole 7, is mutually slidably connected, thus structure between pole 7, in the measuring process of the gradient, according to actual needs, the stroke of main scale 1 and brace 3 is regulated, both can measure the segment gradient, also can measure the mean inclination on longer slope.
Described main scale 1 transversely with is longitudinally respectively equipped with bubbler tube 8, and in bubbler tube 8, envelope has liquid and bubble, structure thus, adjustable main scale 1, makes it be in horizontal or vertical state.
Described main scale 1 both sides are all shaped with scale 2, structure thus, facilitate both sides to observe, and read data.
Described support bar 4 is provided with the mark number of mark pitch number, structure thus, convenient reading pitch number.
Specific embodiment is as follows:
The first step: brace 3 is affixed on inclined-plane and places, main scale 1 is placed on the nut 5 that is threaded with support bar 4.By setting nut 5, and observe the bubble in bubbler tube 8, make main scale 1 terminal level, thus form the right-angle triangle be made up of main scale 1, brace 3 and support bar 4.
Second step: read the number of degrees on scale 2, be designated as L, counts the pitch number from nut 5 lower end to brace 3 and support bar 4 hinged place, is designated as n, according to known pitch a, and the thickness b of nut, by gradient computing formula:
Surveyed gradient size can be obtained.Compare with design grade again, the slope requirement whether tested surface reaches theoretical can be determined.
When being the gradient of vertical plane when needing measuring surface, using method and horizontal survey similar.Only need grade rod vertically to place, by setting nut 5, and observe the bubble in bubbler tube 8, make main scale 1 occupy vertical state.Then lower step repetitive operation is carried out.
