Abstract
The utility model discloses a settlement observation mark comprising an L-shaped measuring bolt 1 and a mark head 2, wherein one side of the L-shaped measuring bolt 1 is provided with an external thread 3; one end of the external thread 3 is connected with the mark head 2; an annular anticollision slot 4 is formed between one end of the external thread 3 and the mark head 2. The settlement observation mark has the beneficial effects that the settlement observation mark can be used for observing the settlement at ordinary times, the L-shaped measuring bolt at one end of the mark head is provided with an external threaded hole for mounting a triple prism for observing the displacement, so that no new observation points need to be reset.
Description
Technical field
The utility model relates to technical field of mapping, relates in particular to a kind of sedimentation observing mark.
Background technology
In order to guarantee the safety of the large-scale structures such as buildings, whether regularly detect its sedimentation situation in architecture construction and use procedure is very important in allowed band, according to the requirement of national project specifications of surveys, the body of wall of Around Buildings distribute be embedded with several to tens permanent markers for detection of its sedimentation situation-building subsidence observation sign.But, when the security situation of the large-scale structures of observation, also need to observe its displacement situation, and displacement observation often needs again to get a little, has caused like this to repeat to get a little, increase the problem of workload.
The utility model content
In order to overcome defects, the utility model provides a kind of sedimentation observing mark.
To achieve these goals, the technical solution of the utility model is: a kind of sedimentation observing mark, comprise L-type survey bolt and sign head, one side that described L-type is surveyed bolt is provided with external thread, described have termination, externally threaded one side to connect the sign head, is provided with annular between termination, externally threaded one side and the sign head and dodges groove.
Further, described L-type is surveyed bolt has the screw thread path on externally threaded one side more than or equal to the maximum gauge of sign head.
The beneficial effects of the utility model are: this is novel can be used for observing sedimentation at ordinary times, and the L-type that indicates first end is surveyed bolt and is provided with outside threaded holes, can install prism, is used for observing displacement, need not re-establish observation station.
Description of drawings
Fig. 1 is front view of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
As shown in Figure 1, a kind of sedimentation observing mark comprises that L-type surveys bolt 1 and sign 2, one side L-type survey bolt 1 be provided with external thread 3, the described termination, one side that external thread 3 arranged connects sign 2, the termination, one side of external thread 3 with indicate 2 between be provided with annular and dodge groove 4.
Further, L-type is surveyed bolt 1 has the screw thread path on one side of external thread 3 more than or equal to the maximum gauge of sign 2.
This novel sedimentation observing mark when normally using, can be used for observing sedimentation, can also fix prism by external thread 3 simultaneously, is used for observing displacement, has reduced the work of setting up displacement observation point.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.
Claims (2)
1. sedimentation observing mark, comprise L-type survey bolt and sign head, it is characterized in that: one side described L-type is surveyed the external thread that is provided with of bolt, described have termination, externally threaded one side to connect the sign head, dodges groove one side be provided with annular between externally threaded termination and the sign head.
2. sedimentation observing mark according to claim 1 is characterized in that: described L-type is surveyed bolt has the screw thread path on externally threaded one side more than or equal to the maximum gauge of sign head.
