Description

A kind of novel planar measuring instrument

Technical field:

The utility model relates to a kind of measuring instrument, especially a kind of novel planar measuring instrument.

Background technology:

Building construction measurement be devise and draw the blueprint and building engineering construction between intermediary, it is operation ahead very important in the work progress, between construction survey quality and the construction quality confidential relation is arranged, to directly have influence on construction quality if measuring process has problem, and cause engineering defective even scrap.This shows, all need to measure in each stage of construction work construction, and the precision of measuring and the speed quality and the progress that directly have influence on whole engineering.Therefore, building engineering survey all has great importance to the quality and safety that guarantees aspects such as engineering programming, design, construction.

From the situation of the present building construction measurement of China, the following problem of ubiquity: survey crew quality is relatively poor and the professional is less; Surveying instrument equipment falls behind and lazy weight; The misoperation and the measuring process of surveying instrument are loaded down with trivial details; The measurement quality control is not in place or the like.And the principal element that improves at China's restriction construction engineering quality at present is exactly the backwardness of domestic surveying instrument equipment.The efficiency of measurement of surveying instrument equipment, measuring accuracy, measuring error, operation complexity will directly influence the quality and the speed of building construction measurement.

Thereby in building construction measurement, the speed and the quality that how to improve construction survey are the problems that we will face and solve.

The general instrument of 2 distances of measurement that exist in the present domestic engineering survey construction has rule (degree of accuracy is 1mm), tape measure (degree of accuracy is 1mm), vernier caliper (degree of accuracy is 0.1mm or 0.01mm), milscale (degree of accuracy is 0.01mm).Their structure is all very simple, and they all need to estimate reading, and personal error is bigger, and wherein the measuring accuracy of rule, tape measure is not high, though vernier caliper, milscale measuring accuracy height, its measurement range is very little.The high new instrument of measuring length has electro-optical distance instrument (comprising laser ranging, infrared distance measurement, pulse ranging, electromagnetic distance measurement), and (measuring accuracy is at 1cm～10m), total powerstation (measuring accuracy 2mm), GPRS (measuring accuracy 10m) or the like, though these instrument measurement ranges are big, but device structure complexity or manufacturing cost height, only being suitable for unit or collective tissue uses, be not suitable for individual in the daily life, groupuscule personnel's use, on small distance, small size, use inconvenience.The equipment volume that has is big, can't lay in a lot of special places; The apparatus expensive that has, individual or groupuscule member do not afford to do.

The direct measurement that exists in the present domestic engineering survey construction not on same vertical plane the instrument of 2 height spirit-leveling instrument, levelling pole etc. are arranged, measuring accuracy is 0.01mm or 0.1mm, though its structure is very simple, the equipment volume that has is bigger, the more important thing is that measuring object is single.

The instrument that takes measurement of an angle that exists in the present domestic engineering survey construction has transit, can only be used for the measurement of angle, and measuring object is single.

The measuring distance simultaneously that exists in the present domestic engineering survey construction and the instrument of angle have total powerstation (range measurement accuracy 2mm, angle-measurement accuracy 2s).
