A kind of projection line-putting method of decorative pattern
[technical field]
The present invention relates to Garden Engineering technical field of construction, especially relate to a kind of central projection line-putting method of decorative pattern.
[background technology]
Along with the maturation day by day of garden landscape industry, the aesthstic cosmetic requirement of garden landscape inscape is more and more higher, and colourful figure line skin texture brings larger challenge to construction, especially more and more higher to the requirement of the construction line-putting.The construction line-putting is step the most basic in Garden Engineering, is the first step carrying out Garden Engineering, and the whether accurate of the construction line-putting is directly connected to the quality height of whole engineering and the quality of landscape effect.Traditional garden layout line-putting method mainly contains square mesh method and surveyor's table combination method, but square mesh method unwrapping wire is a kind of rough evaluation method inherently, the judgment simultaneously implementing again people with unwrapping wire has much relations, so the result of unwrapping wire often has larger deviation; Although surveyor's table combination method is more accurate than simple square mesh method, but it needs drawing to be placed on surveyor's table, execution conditions are affected by climate change larger, simultaneously due to the architectural characteristic of surveyor's table self, cisco unity malfunction in the landform that some are comparatively complicated, therefore its work efficiency is lower, and usable range is subject to certain restrictions.
Along with the development of the development of science and technology, particularly GPS, computer measurement technology and computer aided drawing, the accurate unwrapping wire of Garden Engineering is made to become possibility.But high-precision GPS price is costly, less use in Garden Engineering construction; Total powerstation, as a kind of ground survey instrument of multifunctional efficient rate, in recent years obtain application in construction work and Garden Engineering, but it has more advantages in large area engineering unwrapping wire, in the small scale pattern unwrapping wire of gardens style facing class, be difficult to effective use.
The present invention makes in view of the situation.

[embodiment]
Below in conjunction with accompanying drawing, the technology of the present invention feature is described in further detail so that described those skilled in the art can understand.
A projection line-putting method for decorative pattern, includes following steps:
A, in working drawing, at least three not unique point 3,4,5 point-blank overstriking marks are chosen to the pattern 2 of required unwrapping wire;
B, in working drawing, calculate the coordinate of described unique point 3,4,5 relative coordinate initial point 9, according to the construction surface 1 size relation of working drawing and Practical Project calculate described unique point 3,4,5 in construction surface 1 with the position coordinates of reference point 8; Described reference point 8 can be the arbitrfary point in described construction surface 1.
C, in described construction surface 1, setting-out is carried out to described unique point 3,4,5, the position of point in described construction surface 1 of overstriking mark setting-out;
D, erection projector 6 adjust the distance of itself and described construction surface 1, make the described unique point 3,4,5 in working drawing overlap completely with the point of setting-out in described construction surface 1;
E, in described construction surface 1, carry out the drafting of pattern contour line by the pattern 2 after projection in step B, complete the setting-out work of whole pattern.
Unique point described in the present embodiment is three, be labeled as 3,4,5 respectively, described working drawing is drawn by computer and is projected in the construction surface 1 of Practical Project through projector 6, and described three unique points 3,4,5 are on the edge of construction pattern, and three unique points are not on same straight line.
The method that described step B calculates the position coordinates of unique point 3,4,5 in working drawing is the level of calculating three unique points 3,4,5 relative coordinate initial point 9 and vertical distance, amplify according to the ratio of working drawing and construction surface 1 again, in construction surface 1 optional a bit as a reference point 8, this reference point 8 is equivalent to the true origin in construction surface, calculates the point of setting-out and the level of reference point 8 and vertical distance.Step C re-uses the survey instrument such as ruler or tape measure and carry out accurate setting-out in construction surface 1.Measure the point of setting-out and the level of reference point 8 and vertical distance, as shown in Figure 3, horizontal range a and the vertical distance b of one of them layout point and reference point 8 is measured in proportion according to survey instruments such as the position ruler of unique point in working drawing 3 or tape measures, thus determine the position of this layout point of construction surface 1, other layout point are also as herewith legal position.
Reference point 8 in Fig. 3 can be the arbitrfary point in described construction surface 1, also can be specified point in construction surface 1 to reach certain feature region the object of accurate Drawing of pattern 2 being limited in construction surface 1, if in working drawing using certain unique point as true origin 9, then reference point 8 is then the point of one of them setting-out in construction surface 1.
Described projector 6 must be carried out vertical projection to described construction surface 1 during projection, described construction surface 1 can be vertical plane or the plane of inclination.
Construction surface 1 shown in the present embodiment Fig. 1 is perpendicular, at ground erection projector equipment support 7, adjusts described support 7 and makes its height and described construction surface 1 center in the same horizontal line, to reduce the edge deformation of projection as far as possible; Be convenient to the working drawing after projecting and just cover whole construction surface, described projector 6 is located on described support 7.
Described projector 6 is measuring projector.
The present invention just described construction surface 1 must flatten and clean clean before carry out setting-out to unique point in described construction surface 1.
The relative square mesh method of projection line-putting method of decorative pattern of the present invention and surveyor's table combination method, equipment needed thereby is simple and easy, small investment, and simple and efficient to handle, degree of accuracy is high, reliability is strong, stability is high, be easy to operation and transfer, especially has superiority in the small scale pattern unwrapping wire of gardens style facing class.
Embodiment of the present invention is only the description carried out the preferred embodiment of the present invention; not inventive concept and scope are limited; under the prerequisite not departing from design philosophy of the present invention; the various modification that in this area, engineering technical personnel make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
