Description

Technical Field

[0001] The present invention relates to the technical field of building material measurement, and specifically to a building decoration construction surveying and setting-out measurement device. Background Art

[0002] A building decoration construction surveying and setting-out measurement device is a device used to accurately measure the position and size of the steel structure of the keel to be installed. It is mainly applied in building decoration construction. These devices, through advanced tools such as laser rangefinders, electronic levels, and total stations, help construction workers mark the correct position, length, levelness, and perpendicularity of the steel structure of the keel according to the design drawings. Through precise measurement and setting-out work, it is ensured that the steel structure completely conforms to the design requirements during the installation process, avoiding construction deviations and potential safety hazards. The use of such measurement devices greatly improves the construction efficiency and accuracy, ensuring the overall quality and structural safety of the building decoration project.

[0003] In the prior art, the price of traditional building decoration construction surveying and setting-out measurement devices for steel structures of keels is generally high, making it difficult to popularize in some small-scale or budget-constrained projects. Although these high-price devices have certain advantages in terms of accuracy and efficiency, their high cost limits the choice of many construction units. At the same time, when using the traditional tape measure for measurement of the steel structure of the keel after bending, there are often large errors. The steel structure may bend or deform during the installation process due to factors such as temperature and humidity. The tape measure measurement is easily interfered by these factors and cannot guarantee the accuracy. Such errors will not only affect the installation accuracy of the steel structure of the keel, but may also cause deviations in the building decoration project that do not meet the design requirements, thus affecting the overall project quality and construction progress. In addition, due to error accumulation, rework or readjustment may be required, increasing the construction cost and time and reducing the construction efficiency. For this reason, we propose a building decoration construction surveying and setting-out measurement device. Summary of the Invention

Two second ear pieces 4014 are rotatably sleeved with a second rotating shaft 4015 through bearings, and an upper pulley 4016 is fixedly sleeved outside. The upper pulley 4016 contacts the inner top wall of the keel steel structure 1 near one side, further improving the stability and sliding accuracy of the positioning system.
