Description

A kind of measurement mark

Technical field

The utility model is related to surveying and mapping tool fields more particularly to a kind of measurement to indicate.

Background technology

It is the markstone for demarcating ground survey control point position, surveyor's beacon and other markers for being used to measure to measure mark Common name.It is the various marks being deposited in after Mapping departments establish and measure when measuring on ground, underground or building.At present Common method be on concrete structure, exposed bedrock, dirt floor etc. trepanning either dig pit then pour mortar or Concrete, then traditional control point survey mark inserted in the hole or cheated, mark core will be measured and revealed to outside.But due to measuring Mark is by concreting in ground, and do not repair in time may for concrete cracking after prolonged wind and weather solarization It can cause to measure the loosening indicated, solid metal cylinder is easy to extract from ground, loses once measuring mark, will be unable to obtain There is the loss that can not be remedied in precise leveling data.And the same place measures mark, and frequency of use is higher, abrasion Seriously, after for many years, Marks Illegible Chu cannot use substantially, need to punch on road surface again, new measurement mark is buried in grouting Will.

Utility model content

Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of measurement mark proposed, Suitable for mapping operations, equipment is simple and practical, is hardly damaged.

To achieve the goals above, the utility model uses following technical solution：

A kind of measurement mark, including measure sign body, protection cap, self-locking measurement mark core, mark post and fixinig plate, the survey It is cylindric to measure sign body shape, and upper inner edge has screw thread, and measuring sign body inside center has cylindrical groove, institute It states cylindrical groove and is used for placing interchangeable self-locking measurement mark core, it is cylinder of the top with crosshair that the self-locking, which measures mark core, Shape locking press button is pressed although there is sale in locking press button hardware store in order to obtain self-locking of the top with clearly crosshair Button can arrive the customization of associated production producer, and cost is relatively low, and the mark post is cylindrical posts, and mark post length is to measure sign body 2~3 times of length, the mark post are integrally formed with sign body is measured, and are located at the lower section for measuring sign body, the fixinig plate Centered on be provided with diameter and mark post diameter matches hole tagger, thickness is 1~2mm, and shape is circular or herringbone, Gu Stator is welded on along mark post length direction on mark post, welds one at a certain distance, and each mark post welds 2~4, indicates when measuring After being embedded in ground, fixinig plate can enhance the bond stress for measuring mark and surrounding concrete, and an entirety is formed with road surface, Prevent measure mark under the load actions such as vehicle because sedimentation and it is crooked due to cannot use.

Further, the protection cap side has and measures the matched screw thread of sign body upper inner edge screw thread, top There is flat recess, installation and the dismounting of protection cap to need by special wrench set, the head of the special wrench set and a word in portion Slot matches, and flat recess and special wrench set match, and reduces and measures mark and destroyed and the probability stolen by people.

Compared with prior art, the beneficial effects of the utility model：The utility model proposes a kind of measurement mark, usually When not in use, top has the protection of protection cap, prevent from measuring the crosshair indicated is exposed to road surface and be worn cannot It uses；It is the cylindric locking press button that top carries crosshair that internal self-locking, which measures mark core, and when use clicks, and crosshair is Pop-up, flushes with ground, after use, clicks, and mark core is to retract in the cylindrical groove for measuring sign body, with automatic circle The locking press button principle of pearl pen is identical, and the locking press button is mounted in the cylindrical groove measured inside sign body, if mark Core damages, and alternatively, increases the service life for measuring mark；After measuring mark and being embedded in ground, fixinig plate can increase It is strong to measure the bond stress indicated with surrounding concrete, an entirety is formed with road surface, prevents from measuring mark in the loads such as vehicle work With it is lower because sedimentation and it is crooked due to cannot use；Flat recess and special wrench set match, and reduce measurement mark and are destroyed by people With the probability of pilferage.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to figs. 1 to Fig. 6, a kind of measurement mark, including measure sign body 1, protection cap 2, self-locking measurement mark core 3, mark Bar 4 and fixinig plate 5,1 shape of measurement sign body are cylindric, and upper inner edge has screw thread, measures in sign body 1 There is cylindrical groove, the cylindrical groove to be used for placing interchangeable self-locking and measure mark core 3 at portion center, and the self-locking measures mark core 3 carry the cylindric locking press button 31 of crosshair 32 for top, although there is sale in 31 hardware store of locking press button, in order to obtain Locking press button 31 of the top with clearly crosshair, can arrive the customization of associated production producer, and cost is relatively low.The mark post 4 is circle Cylindricality stock, 4 length of mark post are to measure 2~3 times of 1 length of sign body, the mark post 4 with measure 1 one of sign body at Type is located at the lower section for measuring sign body 1, the thin iron of diameter and the hole of 4 diameter matches of mark post is provided with centered on the fixinig plate 5 Piece, thickness are 1~2mm, and shape is that circular or herringbone, fixinig plate 5 are welded on along 4 length direction of mark post on mark post 4, every Certain distance welds one, and each mark post 4 welds 2~4, and after measuring mark and being embedded in ground, fixinig plate 5 can enhance measurement Mark and the bond stress of surrounding concrete form an entirety with road surface, prevent from measuring mark under the load actions such as vehicle because Sedimentation and crooked and cannot use, 2 side of the protection cap has and measures the 1 matched spiral shell of upper inner edge screw thread of sign body Line, top have a flat recess 21, and the installation of protection cap 2 and dismounting are needed by special wrench set, the head of the special wrench set with The flat recess 21 matches, and flat recess 21 is matched with special wrench set, reduces measurement mark and is destroyed and stolen by people Probability.
