Description
Technical Field
The utility model relates to a lofting instrument specifically is an arc structures lofting instrument.
Background
A large number of special-shaped structures such as landscape weirs, water falling weirs and the like generally exist in ecological riverways, arc paying-off is frequently carried out, and two common methods for arc paying-off are adopted at present: one method is to adopt measuring instruments such as a total station instrument, a tape measure and the like to encrypt coordinates and then carry out arc lofting; the other is to adopt a sizing special-shaped wire laying tool. The first method has the defects of large measuring workload, low efficiency and unsuitability for lofting a large number of special-shaped structures with different radians; the arc formed by the encrypted coordinates is prone to arc-shaped irregularity and offset. The second method has the defects that the specification of the shaping arc-shaped tool is fixed, the radian of the special-shaped structure of the ecological river channel is different, and the special-shaped structure cannot be recycled, so that the resource waste is caused; the shaping arc-shaped tool is made of a single thin material, the radian cannot be finely adjusted, and the phenomenon of irregular arc and offset is easily caused at the damaged part.
Disclosure of Invention
The utility model discloses a solve arc building lofting precision not high and the unable turnover scheduling problem of lofting instrument, provide an arc structures lofting instrument.
Realize the technical scheme of the utility model, an arc structures lofting instrument, including first body, second body and radian fine tuning pole, first body be the arc form, the second body is the arc form, the one end fixed connection of first body and second body, the radian of first body is less than the radian of second body, wear to be equipped with a plurality of radian fine tuning poles between first body and second body, radian fine tuning pole be the bolt, the one end of bolt is located second body lateral surface, the other end of bolt is located the medial surface of second body, and is equipped with the goat's horn nut on the bolt, is equipped with the scale on the medial surface of second body.
The PVC square pipe is characterized in that the first body structure is a PVC square pipe, the second body structure is a PVC round pipe, the materials are simply obtained, the economical efficiency is good, and the flexibility and the toughness are good.
When the utility model is used, the end points at the two ends of the arc of the special-shaped structure are marked in sequence by measuring instruments such as a total station; calculating to obtain the length of the arc by a drawing tool, connecting the standard knots by a plurality of second bodies to obtain corresponding lengths, and enabling two ends of the tool with the corresponding lengths to correspond to end points at two ends of the arc lofting position to form the arc by the characteristics of flexible pipes; by comparing the tangent lengths of the corresponding positions of the plurality of arc sections, manually twisting a goat's horn nut to check the arc smoothness of the flexible pipeline; and lofting according to the second side edge of the first body by using a marking tool.
Compared with the prior device, the utility model has the advantages that:
(1) the arc positioning work can be completed only by measuring two end points of the arc section, the working strength is lower, and the working efficiency is higher.
(2) The utility model discloses the instrument can be connected the use according to special-shaped structures arc length, connects, dismantles easy operation, can have enough to meet the need the use, resources are saved, and the suitability is stronger.
(3) The utility model discloses a contrast several segmental arc tangent length, the smooth check-up of segmental arc smoothness can be accomplished to the hand-twist goat's horn bolt, easy operation, and circular arc smoothness degree is good.
