Before the installation, we must measure all the dimensions, including the measurement of the opening dimensions. I believe that most people do not understand the standard of door opening dimensions and measurement methods. Then, let Xiaobian share the standard of door opening dimensions and measurement methods for everyone. I hope to help everyone.
First, the door hole size standards and measurement methods
1. Actually measure the width and height of the door opening. It is necessary to measure the upper, middle and lower openings of the door hole. If they are inconsistent, the narrowest point shall prevail, but the error shall not exceed 20mm.
2. The wall hole should be corrected for errors exceeding 20mm. The correction can be corrected with cement mortar or lime.
3, measuring the size of the doorway to the amount of upper, middle and lower three, to see if the thickness of the wall is the same, but also depends on the thickness of the left and right walls and door openings on the wall is the same, not the same take their maximum, but The error must not exceed 5mm.
4. If the wall thickness error exceeds 5mm, it needs to be corrected.
5, if the wall is a T-shaped wall, you need to use a blockboard to do a false wall width of 50-60mm placement door line. The thickness is the same as the wall thickness of the wall.
6. The minimum thickness of the door wall is not less than 80mm. The strength of the door frame with a low and 80mm size is not great, and the support of the door is not enough. If less than 80mm, the thickness of the wall needs to be thickened to more than 80mm.
7. When there is a protruding beam above the door hole, the upper door line cannot be installed. It is also necessary to use a blockboard to make a false wall with a height of 50-60mm. The length is the same as the width of the doorway, and the depth is the same as the thickness of the doorway.
8, the door has a step. The face line with a step on one side is to add the height of the step, and the specific size is determined according to the height of the step.
9. The thickness of the bathroom and kitchen door wall should pay particular attention to the thickness of the wall tile. Generally, the single-sided tiling is thickened by 25mm, and the two sides are thickened by 50mm. The specific conditions are signed and confirmed by the designer, the customer and the decoration company. The final size of the door opening includes the thickness of the wall tile, preferably measured after the wall tile is attached.
10. Pay attention to the opening direction of the door when measuring, and the opening direction is defined as: From the front of the door, the hinge is left at the left, and the hinge is at the right at the right.
11. The measurement of mouthpieces and window covers is basically the same as the measurement of door openings, except that the door opening size is recorded according to the actual measurement results without deduction.
Xiao Bian summary: The above is about the door hole size standards and measurement methods, I believe we have read the door hole size measurement has a further understanding. For more decoration knowledge, please continue to pay attention to our website, follow-up wonderful presentation.
