Vault doors are important facilities for financial institutions such as banks and large shopping malls, and their security requirements are very high. Before installing the vault door, the door opening needs to be accurately measured to ensure the proper installation and use of the vault door. This article will introduce the method of measuring the opening of the vault door to ensure the smooth installation of the vault door.
1. Preparation before measurement.
Before carrying out the door opening measurement, the following preparations need to be made:
1.Determine the measurement reference point: According to the size and installation position of the vault door, determine the measurement reference point, usually choose the middle point of the door opening as the reference point.
2.Clean the door opening: Clean up the debris and dust in the door opening so that accurate measurements can be made.
3.Prepare measuring tools: Prepare measuring tools, angle rulers, levels and other measuring tools to ensure the accuracy and reliability of the tools.
Second, the measurement method of the door opening.
The measurement of the door opening mainly includes the measurement of width, height and depth, and the specific methods are as follows:
1.Width measurement: Use a measuring ruler or laser rangefinder to measure the width of the door opening, and ensure that the ruler or rangefinder is perpendicular to the ground during the measurement to avoid errors. At the same time, the distance between the left and right sides needs to be measured separately, and the average value is taken as a determined width value.
2.Height measurement: Measure the height of the door opening with a measuring ruler or laser rangefinder, making sure that the ruler or rangefinder is perpendicular to the ground while measuring. At the same time, the height of the upper and lower parts of the door opening needs to be measured separately, and the average value is taken as the determined height value.
3.Depth measurement: Use a measuring tape or laser rangefinder to measure the depth of the door opening, i.e. the distance from the inside to the outside of the door opening. It is also necessary to measure the distance on the left and right sides separately and take the average value as a determined depth value.
4.Angle measurement: Use a tool such as a ruler or total station to measure the angle of the doorway, especially if there is an angle of inclination in the doorway. It is necessary to measure the angles of the left and right sides of the door opening separately, and take the average value as the determined angle value.
5.Other details measurement: According to the special requirements of the vault door, it may also be necessary to measure the flatness, verticality and other details of the door opening to ensure the smooth installation and use of the vault door.
3. Precautions.
When measuring the door opening, you need to pay attention to the following:
1.Guarantee the accuracy of the measurement: In order to ensure the smooth installation and use of the vault door, the accuracy of the measurement needs to be guaranteed. Especially when measuring width, height and depth, it is necessary to double-check the data to avoid errors.
2.Be aware of security issues: Since vault doors are usually installed in financial institutions, security needs to be taken when taking door openings. Ensure that safety measures are in place in the work area, such as setting up warning lines, warning signs, etc.
3.Follow relevant codes and standards: When measuring door openings, it is necessary to follow relevant codes and standards, such as quality acceptance specifications for building decoration projects. At the same time, it is also necessary to measure according to the installation requirements provided by the manufacturer of the vault door to ensure the correct installation and use of the vault door.
Fourth, summary. This article introduces the methods and precautions for measuring the door openings of the vault door. When measuring the door opening of the vault, it is necessary to follow the relevant norms and standards to ensure the accuracy of the measurement, while paying attention to safety issues. Proper door opening measurement can ensure smooth installation and use of vault doors and improve the security of financial institutions.
