Description

A kind of miniature antarafacial tracerse survey instrument

Technical field

The utility model relates to building engineering construction field, particularly relates to a kind of miniature antarafacial tracerse survey instrument.

Background technology

At present in China's Building Construction, construction survey instrument mainly comprises the accurate measurement instrument devices such as total powerstation, spirit-leveling instrument, transit, stadimeter, and these high-end accurate measurement instrument devices all rest in professional and technical personnel's hand, and these instrument and equipments are expensive; Because in work progress, survey speciality technician can not carry out measurement and positioning unwrapping wire to local fine dimension, the O. gracilipes (as: measurement of verticality, space antarafacial anti-line) of vast common construction operation personnel (as: carpenter, riveter, pipeliner, bricklayer etc.) to local all adopts line to fall and measures.

Line pendant is the conventional tool of antarafacial messenger wire and squareness measurement, is widely used in all kinds of staff's hand, comprises quality check and inspector, universal use.But line pendant has following defect, can not reach the object accurately measured.

1, poor stability: because air exists air current flow during line pendant messenger wire, high aerial wind-force is larger; The breathing of operator's human body, the stability of hand and surrounding environment influence, line pendant swings under adverse condition environment, and center of gravity and the line body deformability of line pendant easily produce deviation, causes accuracy to be difficult to control, inefficiency.

2, measuring accuracy is poor: the standing place (center side-play amount and measuring distance) of survey crew is different with method of sight, and take measurement of an angle and certainly exist difference, measuring accuracy also there are differences; Line pendant is in measuring process, and line pendant, owing to being subject to backlight, the unfavorable luminous environment impact of light-metering, producing the unfavorable factors such as vignette, causes measurement precision difference and inefficiency.

3, due to the impact of operator's individual factor when line pendant is measured, affect by the technical merit of construction operation personnel, physical factors.Test shows: the workman with certain technical merit carries out messenger wire under same environment, same position, and average error generation rate is 82%, and average measurement disqualification rate 11%, accurate rate only has 7%.Measuring error cumulative sum disqualification rate is the principal element causing engineering survey quality.Shown by above data: line pendant messenger wire technology by Personnel Skill Levels and individual parallax effects very large.Therefore; Line pendant messenger wire technology, being the standard embodying workman's technical merit ability, is the key point manufacturing specification product.The general personnel that all selection technique level is high when key position is measured implement.

4, measuring distance is short: effective elongated distance 1.5m of line pendant, the error produced when being greater than 1.5m just strengthens gradually.

In building operation, process equipment installation, decorations field, because the accurate measurement instrument devices such as total powerstation, spirit-leveling instrument, transit, stadimeter are expensive, cause still using original simple and crude line to fall and determine surveying setting-out quality level with the technical merit factor of people, this is China's building operation, process equipment is installed, main cause that the quality level such as decorations field and product physical dimension can not improve.
