Engineering cost measuring ruler for field measurement

Abstract

The invention discloses an engineering cost measuring ruler for field measurement, and belongs to the field of engineering cost equipment.The engineering cost measuring ruler for field measurement comprises a shell, a communicated rope outlet is fixedly formed in the outer end wall of the shell, and a wrapping post is rotationally connected to the interior of the shell; a round rope is wound on the outer side of the wrapping post, two vertically symmetrical wheel discs are rotationally connected into the rope outlet, length measurement is conducted by stretching the round rope, the total length of the adjacent bent faces on the construction site can be directly measured by means of the flexibility of the round rope, measurement operation is more convenient and faster, meanwhile, the positioning rod is connected with the round rope, and the measurement accuracy is improved. The circle drawing operation can be carried out by taking the round rope as a reference point and taking the extending length of the round rope as the radius, and an additional compass drawing device does not need to be arranged, so that the applicability of the device in a project cost measuring field is improved to a certain extent.

Description

technical field [0001] The invention relates to the field of engineering cost equipment, and more specifically relates to a measuring ruler used for on-site measurement of engineering cost. Background technique [0002] Project cost refers to the construction cost that constitutes the estimated or actual expenditure of the project during the construction period. In the existing technology, in order to ensure that the construction of the project project is more scientific and reasonable, the project cost is predicted, planned, controlled, calculated, Analysis and evaluation are particularly important. [0003] In the actual evaluation of project cost, staff usually need to conduct on-the-spot measurement and survey on the construction site. During on-site measurement, measuring devices such as measuring ruler or measuring pen are usually used. In actual use, the measuring ruler in the prior art Most of the measuring pens can only measure the length of a straight line. If you...

[0003] In the actual evaluation of project cost, staff usually need to conduct on-the-spot measurement and survey on the construction site. During on-site measurement, measuring devices such as measuring ruler or measuring pen are usually used. In actual use, the measuring ruler in the prior art Most of the measuring pens can only measure the length of a straight line. If you need to measure the total length of multiple continuous surfaces, you need to measure the lengths of multiple surfaces individually, and then calculate the total value by adding. It is difficult to directly measure the total length of straight lines on multiple surfaces, which makes it inconvenient to use, and most of the measuring rulers in the prior art are only suitable for length measurement, which is difficult to meet the complex needs of the construction site
