Abstract

The invention discloses an adjustable and reusable arc-shaped positioning pay-off device. The adjustable and reusable arc-shaped positioning pay-off device comprises a pay-off plate; a supporting plate, wherein the two ends of the pay-off plate are detachably fixed to the supporting plate through fastening structures; and electric push rods which comprise a middle push rod body and at least one pair of side push rod bodies, wherein the middle push rod body is arranged in the middle of the supporting plate, the movable end of the middle push rod body is fixedly connected with the middle of the pay-off plate, the side push rod bodies are symmetrically arranged on the two sides of the middle push rod body, and the fixed ends of the middle push rod body and the side push rod bodies are fixedly connected with the supporting plate, so that the movable ends of the electric push rods can abut against the pay-off plate after extending. The invention further provides a pay-off method of the adjustable and reusable arc-shaped positioning pay-off device. The pay-off device can be used for convenient and quick adjusting to obtain a required arc, and has the characteristics that the precision of the formed arc is higher and the like.

Description

technical field [0001] The invention relates to the field of line rulers. More specifically, the present invention relates to an adjustable and reusable arc-shaped positioning pay-off device and a pay-out method thereof. Background technique [0002] The application of special-shaped building structures in modern construction projects has become more and more widely used. The traditional measurement and setting-out positioning method has the disadvantages of low efficiency and difficult quality control in the measurement, positioning and setting-out of special-shaped structures. At the same time, arc-shaped structures have higher and higher requirements for engineering surveys. During the setting-out measurement process of large-scale arc-shaped structures, the vertical transmission distance between the plane control network and the elevation is long, and many measuring station conversions are required. The cumulative measurement error is large, and often The building eleva...
