Description
Technical field
The utility model relates to Construction Technology fields, and in particular to a kind of simple protective device, it is embedded for protecting
Interim measurement mark in underground.
Background technique
Measurement mark (survey mark) be demarcate the markstone of ground survey control point position, surveyor's beacon and other be used for
The common name of the marker of measurement is deposited on ground, underground or building after Mapping departments establish and measure in measurement
Various marks.Each measurement mark finds out its plan-position and height above sea level on the ground by accurate measurement, calculating
Altitude data.
Measurement mark is divided into permanent surveying market and provisional measurement mark.Permanent surveying market refers to each grade
Wooden the observing of triangulation point, baseline point, traverse point, military control point, gravity station, astronomil, bench mark and global positioning satellite point
Mark, steel surveyor's beacon and stone marker, and fixed signal and seabed the earth for topographic mapping, engineering survey and distortion measurement
Point facility.Provisional measurement mark refers to that surveying and mapping unit is arranged and uses in measurement process, does not need after work long-term
The mark and label of preservation, such as survey station point timber, activity see mark, surveys flag, measuring staff, aeroplane photography surface mark, on ground or builds
(structure) builds label on object etc..
For interim measurement mark often because construction interference is destroyed, point benefit survey is comparatively laborious in tunnel at present, is related to conducting wire
Encryption and compensating computation, measurement reproducibility is high, larger workload.Therefore it is badly in need of a kind of simple protective device of low cost, is used for
Interim measurement mark is against damages under protecting field.
Utility model content
In view of the above technical problems, the utility model is intended to provide a kind of structure and is simple and convenient to operate, is at low cost, occupying
The small simple protective device in space, it is against damages for interim measurement mark under protecting field.
For this purpose, technical solution used by the utility model is：A kind of interim measurement mark simple protective device, including water
Plain plate and connector, the connector are embedded in concrete, and the upper end of connector has anti-drop hook, the horizontal steel
The side of plate is provided with mounting hole, and is rotatably installed on the anti-drop hook of connector by mounting hole, and horizontal steel plate can be horizontal
The surface of underground interim measurement mark is turned to, be staggered underground interim measurement mark after capable of also horizontally rotating, and horizontal steel plate
There are distances between the interim measurement mark of underground.
The connector is bent into " u "-shaped by steel bar as a preferred embodiment of the above solution, and the vertical bending in the upper end of steel bar is constituted
The anti-drop hook, the vertical bending in the lower end of steel bar form anticreep eave tile.Simplify the structure of connector, both by "u"-shaped
It can prevent horizontal steel plate from falling off, and generate loosening, and connector integral strength in concrete after connector stress can be prevented
It is good.
Further, the length of the anticreep eave tile is greater than the length of anti-drop hook, reduces the length of anti-drop hook, saves material
Material.
Further, the horizontal steel plate is circular steel plate, and mounting hole is eccentrically set in circular steel plate, the horizontal steel
The top surface of plate is flushed with ground, mounting hole and connector clearance fit, and convenient vehicle above the ground passes through, and horizontal steel plate
Rotary resistance is small.
The beneficial effects of the utility model：Connector is used for for connecting horizontal steel plate and concrete, horizontal steel plate drilling
Installation connecting element, horizontal steel plate are placed in interim measurement mark the preceding paragraph distance, and horizontal steel plate can be rotated around connector.Need using
When temporary sign, steel plate is rotated around connector, is resetted after use, indicates daily protection for measuring.Structure is simple, operates
It is convenient, at low cost, occupy little space, can effectively prevent the destruction to interim measurement mark of driving a vehicle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1, Figure 2, a kind of interim measurement mark simple protective device, mainly by horizontal steel plate 1, connector 2
Composition.
Connector 2 is embedded in concrete, and the upper end of connector 2 has anti-drop hook 2a.
Preferably, connector 2 is bent into " u "-shaped by steel bar, and the vertical bending in the upper end of steel bar constitutes anti-drop hook 2a and is used for
Horizontal steel plate 1 is installed, the vertical bending in the lower end of steel bar forms anticreep eave tile 2b for being stabilized in concrete.Anticreep eave tile 2b's
Length of the length more preferably greater than anti-drop hook 2a.
The side of horizontal steel plate 1 is provided with mounting hole 1a, and the anti-drop hook of connector 2 is rotatably installed in by mounting hole 1a
On 2a.Horizontal steel plate 1 can horizontally rotate the surface of underground interim measurement mark 3, play to underground interim measurement mark 3
Protective effect, for example prevent driving from damaging to underground interim measurement mark 3；Also the underground that is staggered after capable of horizontally rotating temporarily is surveyed
Mark 3 is measured, underground interim measurement mark 3 is exposed, is easy to use interim measurement mark 3.Horizontal steel plate 1 and underground interim measurement
There are distances between mark 3, prevent horizontal steel plate 1 from acting directly on the interim measurement mark 3 of underground.
Preferably, horizontal steel plate 1 is circular steel plate, and mounting hole 1a is eccentrically set in circular steel plate；Certainly, horizontal steel plate
1 can also be using rectangular or other shapes of steel plate.The top surface of horizontal steel plate 1 is flushed with ground, between mounting hole 1a and connector 2
Gap cooperation.
