Abstract
The utility model discloses a combined survey mark belongs to the engineering survey field, including steel nail and ring, the steel nail includes the head of a nail and nail needle, and head of a nail upper surface is carved with two quadrature nicks, and the ring center is provided with the through -hole, and diameter of hole slightly is greater than the nail needle, and the nail needle can pass the ring through -hole. The utility model discloses a make up the mark of measuring the position with steel nail and ring, more traditional survey mark easily looks for, and construction convenience, swift simultaneously is particularly suitable for measuring under the campus bituminous paving or the cement road surface circumstances real the laying of control point of instructing.
Description
Technical field
This utility model belongs to engineering survey field, particularly to a kind of combined surveying marker.
Background technology
Engineering survey real training is that colleges and universities' relevant speciality carries out the important step measuring education, and a precondition of measurement real training is: lays in campus and measures control point.At present, the main laying form measuring control point in colleges and universities is: follows closely cement nail on road surface, campus, is then labeled near this cement nail with red paint etc..The prominent shortcoming of this laying form is: cement nail gets rusty easily, and paints disappearance of easily fading, substantially per will re-start a control points layout term, and repetitive operation is more.
Utility model content
This utility model be in that provide a kind of mark and be easy to search combined surveying marker, be particularly suitable in campus bituminous paving or cement pavement situation measure real training control point laying.
In order to achieve the above object, the technical scheme is that
A kind of combined surveying marker, including steel nail and annulus, described steel nail includes the head of a nail and nail pin, and described head of a nail upper surface is carved with two orthogonal indentations, and described circle ring center is provided with through hole, and through hole outer annular diameter is slightly larger than nail pin, and nail pin may pass through annulus through hole.
It is provided that further
The described head of a nail is circular, is provided with groove in described annulus, and groove is in the annular centered by through hole, and the diameter of groove is slightly larger than the diameter of the head of a nail, and nail pin is after annulus through hole, and the head of a nail can be inserted in the groove of annulus.
Described annulus is the thin ring of aluminum.
The diameter of the described head of a nail is 1.5 centimetres.
The outer annular diameter of described annulus is more than or equal to 5 centimetres.
The material of described steel nail is rustless steel.
The material of described steel nail is high-strength stainless steel.
This utility model is by the labelling of the measurement point position that steel nail and annulus combined, and relatively traditional measurement mark is prone to search, simultaneously easy construction, quick, is particularly suitable in campus bituminous paving or cement pavement situation measuring the laying at real training control point.

Label declaration
Combined surveying marker 30, steel nail 10, annulus 20, the head of a nail 11, follow closely pin 12, orthogonal indentation 13, through hole 21, groove 22.
Detailed description of the invention
A kind of combined surveying marker 30, including steel nail 10 and annulus 20, steel nail 10 includes the head of a nail 11 and nail pin 12, and the head of a nail 11 upper surface is carved with two orthogonal indentations 13, for the centering of the instrument such as theodolite, total powerstation.Annulus 20 is provided centrally with through hole 21, and through hole 21 diameter is slightly larger than nail pin 12, and nail pin 12 may pass through annulus through hole 21.
In order to steel nail 10 and annulus 20 are fixed, prevent displacement, the head of a nail 11 is provided in round shape or polygon, circular shape, is provided with groove 22 in annulus 20, groove 22 is also in the annular centered by through hole, the outer annular diameter of groove 22 is slightly larger than the diameter of the head of a nail 11, nail pin 12 is after the through hole 21 of annulus 20, and the head of a nail 11 edge inserts in groove 22 along the outer shroud of groove 22, and it has the effect of easy construction, difficult drop-off.
For the ease of carrying and reduce cost, annulus 20 is the thin ring of aluminum.
For saving material, the head of a nail 11 is little compared with the head of a nail size that general measure is followed closely, and diameter is 1.5 centimetres.
For convenience of labelling, and highlighting labelling and be easy to search, the outer annular diameter of annulus 20 be more than or equal to 5 centimetres, can be used for carving annotation such as organization, control period etc.；
In order to increase the service life of steel nail 10, it is prevented that steel nail 10 gets rusty, the material of steel nail 10 is rustless steel, it is preferable that high-strength stainless steel.
This utility model is by the labelling of the measurement point position that steel nail 10 and annulus 20 combined, and relatively traditional measurement mark is prone to search, easy construction simultaneously, quick, is particularly suitable in campus bituminous paving or cement pavement situation measuring the laying at real training control point.
Above example is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that the technical solution of the utility model is made by those of ordinary skill in the art or equivalent replace, without departing from the spirit and scope of technical solutions of the utility model, all should be encompassed in right of the present utility model.
