The invention discloses a multi-specification universal lofting device for a straight arrow of a traffic orientation arrow. The multi-specification universal lofting device consists of an angle framing mark, two foldable waistline templates and three bottom line templates, wherein each foldable waistline template is assembled by three sections of laths through sleeve type bidirectional folding hinges. The multi-specification universal lofting device can be applied to construction lofting of the straight arrows of the traffic orientation arrows with three different specifications through folding or unfolding, more than one half of manpower resources can be saved, and the lofting device is convenient to collect and transport.
Description
Technical field: [0001] The invention relates to a road marking drawing tool, in particular to a multi-standard flexible stakeout device for straight-pointing arrows of traffic guiding arrows. Background technique: [0002] On the roads and sites where vehicles are allowed to pass or park, traffic directional arrows must be marked. Since there are many types of arrowheads, and the sizes and specifications are also divided into three grades, it is necessary to have more than two personnel with a considerable level of knowledge in the implementation of lofting, which consumes a lot of human resources; It is necessary to fill a truck, and it is difficult to find it when using it. Invention content: [0003] In order to simplify the construction and stakeout work of traffic-oriented arrows, the present invention provides a multi-standard flexible stakeout device for direct-pointing arrows of traffic-oriented arrows. Each of the strips is a foldable waistline template compose...
