Measuring device for civil engineering

Abstract

The invention provides a measuring device for civil engineering. The measuring device for civil engineering comprises a measuring plate, a sliding cavity, two sliding blocks, two ruler plates and twopositioning blocks, wherein the sliding cavity is formed in the measuring plate; the two sliding blocks are slidably mounted in the sliding cavity; the two ruler plates are slidably mounted on the inner walls of the two sides of the sliding cavity correspondingly, the sides, close to each other, of the two ruler plates extend into the sliding cavity and are fixedly connected with the two sliding blocks correspondingly, and the sides, away from the two sliding blocks, of the two ruler plates extend out of the measuring plate; and the two positioning blocks are fixedly mounted on the sides, awayfrom the two sliding blocks, of the two ruler plates correspondingly. The measuring device for civil engineering has the advantages of being convenient to mark, having a telescopic function and having a reference target.

Description

technical field [0001] The invention relates to the technical field of civil engineering measurement, in particular to a measuring device for civil engineering. Background technique [0002] When constructing buildings in civil engineering, some measuring devices are needed, such as some total stations, tape measures and ruler boards. When the distance is long, people usually use total stations for positioning measurement. When the distance is medium, people usually use Using a tape measure, when the distance is small, it is usually measured by a ruler board for the convenience of people. When using the ruler board, due to the limited distance, people only need to hold the ruler board to measure when using it. Measuring the distance is a construction process. One of the most common and important measurement data. [0003] However, when people measure with the ruler board, they find that due to the limited distance of the ruler board, people need to move the ruler board mult...

Problems solved by technology

[0003] However, when people measure with the ruler board, they find that due to the limited distance of the ruler board, people need to move the ruler board multiple times to make more accurate measurements. When moving the ruler board, people need to manually mark the last measurement point, which is inconvenient. At the same time, because the size of the ruler plate is relatively fixed, it usually does not have the ability to expand and contract. In the final measurement, sometimes the other end of the ruler plate needs to be in conflict with the measurement. When people need to measure the roundness of a round object, they need to replace the measuring tool. It is inconvenient, and most of the current ruler boards do not have long-distance reference devices, and it is inevitable that deviation will occur when moving multiple times
