Description
Technical Field
The utility model relates to the technical field of surface measurement and monitoring, in particular to an upgraded and improved measurement mark.
Background
At present, surface engineering measurement and monitoring are an indispensable part in most project construction, and measurement marks are widely applied to the surface with measurement or monitoring requirements. The monitoring of the surface subsidence is the important thing during the engineering construction, if the monitoring of the surface subsidence is not carried out during the construction, then will probably cause major engineering accident at last, consequently set up the survey mark when the construction just in order to monitor the surface subsidence in time, avoid the emergence of accident.
Although conventional survey markers may help monitor surface subsidence, there are still some problems in use, such as: some measuring marks do not need to be monitored after project construction is completed, but the measuring marks are abandoned due to the fact that the measuring marks are taken out too inconveniently, resource waste is caused, and construction cost is improved; after the measuring marks are embedded into the ground, the anchoring force between some measuring marks and the ground is not strong, and the measuring marks are easily damaged by external force. Therefore, there is a need for an upgraded measurement flag.
Disclosure of Invention
In order to solve the problems of resource waste and poor anchoring force caused by inconvenient disassembly after the existing measuring mark is used, the utility model provides an upgraded and improved measuring mark, which effectively solves the problems, reduces the resource waste and increases the anchoring force between the ground and the measuring mark.
The utility model adopts the following technical scheme:
the utility model provides a survey mark of upgrading transformation, comprises screw rod main part, expansion sleeve, hexagon nut, gasket and cap nut, the expansion sleeve is sheathe in earlier to the screw rod main part and screws up hexagon nut, then imbeds monitoring point with it, and the gasket is added after the spanner is fixed for use, screws up the cap nut that the top was carved with the spill cross at last.
Preferably, the expansion sleeve, the hexagonal nut, the spacer and the cap nut of the measuring mark are connected by the screw body to form a whole.
Preferably, the screw body bottom diameter is slightly larger than the diameter of the expansion sleeve.
Preferably, the measuring sign bottom rod body becomes a combination of the screw body, the expansion sleeve and the hexagonal nut.
Preferably, the spacer of the measuring mark and the cap nut are detachable.
The utility model has the beneficial effects that: (1) compare in traditional integral type survey mark, the novel survey mark after the transformation comprises each part, and convenient the dismantlement, partial part can dismantle reuse after the monitoring is accomplished, has effectively reduced construction cost. (2) Compared with the stress principle that the traditional measuring mark is directly embedded, the novel measuring mark is improved according to the stress principle of the expansion screw, the anchoring strength of the expansion screw during working is greatly improved by means of the friction force between the expansion sleeve and the embedded hole, which is deformed due to stress, and the reliability of the measured data is ensured.
Drawings
FIG. 1 is a schematic structural view of the present invention.
FIG. 2 is a detailed view of the structure of the components of the present invention.
In the figure, 1 is a screw body, 2 is an expansion sleeve, 3 is a hexagon nut, 4 is a gasket, and 5 is a cap nut.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
the utility model provides a survey mark that upgrading was reformed transform, comprises screw rod main part 1, expansion sleeve 2, hexagon nut 3, gasket 4 and cap nut 5, expansion sleeve 2 is sheathe in earlier to screw rod main part 1 and the hexagon nut 3 is twisted, then imbeds the monitoring point with it, and the back is fixed well with gasket 4 for use spanner, twists the cap nut 5 that the top was carved with the spill cross at last.
The measuring mark is composed of a screw rod main body 1, an expansion sleeve 2, a hexagonal nut 3, a gasket 4 and a cap nut 5, and the hexagonal nut 3, the gasket 4 and the cap nut 5 can be detached for recycling after the later monitoring is completed, so that the resource waste is reduced, and the construction cost is reduced.
The screw rod main body 1, the expansion sleeve 2 and the hexagonal nut 3 work according to the stress principle of the expansion screw, the anchoring strength of the measuring mark at work is greatly improved by means of the friction force between the expansion sleeve 2 and the embedded hole, the deformation of the expansion sleeve is caused by stress, the influence of external force on the measuring mark is reduced, and the reliability of measured data is effectively guaranteed.
When the device is used, firstly, a pre-buried hole is drilled at a point to be tested by an electric drill, then the assembled screw rod main body 1, the expansion sleeve 2 and the hexagon nut 3 are hammered into the pre-buried hole, then the hexagon nut 3 is screwed by a spanner, so that the screw rod main body is firmly fixed at the pre-buried hole by virtue of the friction force between the expansion sleeve 2 and the pre-buried hole, which are deformed due to stress, and finally, the gasket 4 is placed and the cover type nut 5 is screwed by the spanner.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
