Horizontal plane level measuring instrument for constructional engineering

Abstract

The invention discloses a horizontal plane measuring instrument for constructional engineering, and relates to the technical field of constructional engineering. The horizontal plane measuring instrument of the present invention includes a movement device, a gradienter is fixed in the middle of the upper surface of the moving device; supports are fixed to the upper surface of the movement device and located on the two sides of the gradienter. The waist parts of the two brackets are respectively in running fit with an unwinding device and a winding device; a paper winding roller is rotatably matched with the top end of the support, a paper roll wraps the peripheral side face of the winding device, one end of the paper roll sequentially bypasses the paper winding roller to be connected withthe unwinding device, a sliding block is slidably matched with the inner top of the gradienter, a floating ball is fixed to the bottom of the sliding block, and a marking pen is inserted into the topend of the sliding block and connected with one surface of the paper roll. According to the invention, the paper roll is rolled while the moving device moves at a constant speed, and the ground flatness data, which comprises bulges and recesses on the ground, in the linear movement process of the moving device is recorded through the cooperation of the paper roll and the marking pen.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a plane level measuring instrument for construction engineering. Background technique [0002] Construction engineering, as a part of construction engineering, refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines, and equipment. Including factories, theaters, hotels, shops, schools, hospitals and residences, etc., to meet people's needs for production, living, learning, and public activities. In construction engineering, it is often necessary to measure the horizontal position in an area, which requires the use of a spirit level, which uses the characteristic that air bubbles always float on the highest water surface to judge whether the area is level or to measure the level position. Marking is a relatively convenient level dete...

Problems solved by technology

[0003] The current spirit level has been developed relatively well, and can basically complete the marking of the horizontal position, but at the same time, the current spirit level needs to be adjusted to the level before marking the horizontal position. Diameter, when it is observed that the bubble is roughly directly above the level, it is judged as a horizontal position, and there is still a certain error; moreover, the data collection of the traditional level is relatively scattered, and it is impossible to intuitively indicate the flatness of the ground
