Description
Technical field
The present invention relates to be used in the digital building mapping indicate the aid that modeling indicates line, takes graticule modeling photo, be mainly used in architectural mapping field in modern times.
Background technology
At present, known architectural mapping method is " a traditional architecture mapping method ", and its range of application comprises the ancient building mapping, also comprises the architectural mapping in modern times.After " traditional architecture mapping method " refers to that nineteen thirty Zhu Qiqian foundes " Chinese tectonics society ", architectural mapping method on the Modern Significance that China first generation architect Liang Sicheng, Liu Dunzhen etc. introduce Western Modern architectural mapping method, found in conjunction with the Chinese ancient architecture feature also continued into the present for Chinese architecture mapping circle's widespread use afterwards always.Promptly continue this architectural mapping method as regular higher education civil engineering subject specialty Tenth Five-year plan teaching material " ancient building mapping ".(referring to the Wang Qiheng chief editor, the Wu green onion is established an army in vain and writes. ancient building mapping [M]. and Beijing: China Construction Industry Press, 2006)
One of disadvantage of traditional architecture mapping method is the pile mapping that need scaffold erecting, if do not scaffold erecting, the elevation of building schema mapping of the construction site that the mapping person can not directly contact can't be surveyed and drawn.Scaffold erecting and need expend a large amount of financial resource and material resource, this increases substantially the cost of architectural mapping; Ce Hui pile does not possess the condition that scaffolds erecting if desired, will the mapping of elevation of building schema mapping can't be carried out.
Summary of the invention
The purpose of this invention is to provide a kind of graticule and photography-assisting tool that is used for the digital building mapping, being used to be implemented under the prerequisite that pile do not scaffold erecting, to the mapping person can not construction site direct control, that be higher than the mapping person position the mapping of digital building facade schema mapping.
For achieving the above object, the technical solution used in the present invention is: this graticule and photography-assisting tool that is used for the digital building mapping comprises elevating lever, control lever and control cord, the top of described elevating lever is provided with rotatable motion bar, described rotatable motion bar is coaxial with the body of rod of described elevating lever, described control lever is fixedlyed connected with rotatable motion bar, the length direction of described control lever and the length direction of rotatable motion bar form an angle greater than zero, and the two ends of described control lever are connected with described control cord respectively.
Further, control lever of the present invention is vertical mutually with rotatable motion bar.
Further, the present invention is the center with the fixed connection place of described control lever and rotatable motion bar, and described control lever is symmetry status.
Further, the present invention is fixedly connected with Laser Line Marker erecting frame or photography holder on described rotatable motion bar.
Compared with prior art, the invention has the beneficial effects as follows: (1) the present invention is simple in structure, and is easy to use.(2) under the prerequisite that does not scaffold erecting, use prior art, promptly use the traditional architecture mapping method can't survey and draw the construction site that the mapping person can not directly contact in the pile, this causes the mapping of elevation of building schema mapping to implement.Owing to use graticule of the present invention and photography-assisting tool control Laser Line Marker accurately to locate, utilize Laser Line Marker to indicate the modeling sign line that this pile is higher than the construction to be measured position outside surface of mapping person position; Use graticule of the present invention and photography-assisting tool control camera accurately to locate, utilize camera to take the graticule modeling photo of this construction site, and then finish mapping to the digital building facade schema mapping of this construction site, thereby under the prerequisite that does not scaffold erecting, the mapping of using the elevation of building schema mapping that prior art can't finish is finished in the final mapping that realizes the digital building facade schema mapping of pile.(3) the present invention is the aid of the mapping of the digital building facade schema mapping of enforcement pile that do not scaffold erecting, and the mapping pile that do not scaffold erecting can be saved the expense that scaffolds erecting, and reduces the cost of architectural mapping significantly.
