A measuring instrument used in multiple environments for building construction surveying and mapping

Abstract

The invention discloses a measuring instrument for building constriction surveying and mapping in multiple environments. The measuring instrument for building constriction surveying and mapping in themultiple environments structurally comprises a surveying and mapping instrument, a positioning supporting disc, three foot stools, foot supports and fixed frames, the surveying and mapping instrumentis fixed to the upper end position of the positioning supporting disc, the three foot stools are in an equilateral triangle shape and distributed and fixed to the lower end position of the positioning supporting disc, the foot supports are arranged at the lower ends of the foot stools, and the foot stools are connected mutually through the fixed frames. According to the measuring instrument for building constriction surveying and mapping in the multiple environments, the foot supports arranged on the foot stools can be rotated and folded up and down, the foot supports are bent downwards whenfacing the cement ground, the ground is supported by the foot supports, the iron pickaxe tail ends of the foot stools are isolated from the cement ground so as to protect an iron pickaxe from being worn due to contact with the cement ground and face the oblique ground by adjusting the length of a middle shaft rod, it is ensured that the opening and closing degree of the foot stools always improvesthe measuring precision through the supporting of the fixed frames, when the iron pickaxe faces soil sandy ground, a material discharging groove adopting a thread shape is formed in the iron pickaxe,soil sand can be discharged through the material discharging groove when being inserted into the soil sandy ground, and the iron pickaxe is more conveniently inserted into the ground.

Description

technical field [0001] The invention relates to the field of architectural surveying and mapping, in particular to a measuring instrument used in multiple environments for architectural construction surveying and mapping. Background technique [0002] Measuring instruments are mainly used for measuring instruments on construction sites. When measuring, the benchmark pole and the horizontal plane are required to be vertical to ensure the measurement accuracy. At present, most of the base frames in the measurement are sharp corner frames, which are easily affected by different terrains. When the end of the bottom frame is worn with the cement on the cement floor, errors are prone to occur. On the soil and sand, the bottom frame is not easy to penetrate into the soil and sand, which increases the difficulty of use. Contents of the invention [0003] In view of the above problems, the present invention provides a measuring instrument used in multiple environments for building ...
