Method of measuring the size of the door opening

Bedroom door hole measurement: When measuring the door hole, you first need to measure the height of the door hole. The height is the height from the ground to the top of the door hole. Both sides need to be measured. The width of the door hole should be divided into upper, middle and lower points. The inner and outer holes should be measured to see if the data is consistent. When measuring the thickness of the wall, it is also necessary to divide the middle and lower points, and the same two must be measured. Finally, the measurement results are recorded on the wall.

Kitchen and bathroom door hole measurement: It is basically the same as the bedroom door measurement method, but it should be noted that when measuring the blank room, the thickness of the tile should be taken into account, so it is necessary to add 2 to the measured data. Centimeters.

Sliding door single-faced door hole measurement: The height, width and thickness of the wooden hole are measured separately, which is consistent with the measurement method of the bedroom door hole.

Entrance door single-sided cover hole measurement: first measure the height; then measure the width, because there is no threshold on the right side of the entrance door, it will lead to the installation of the entire wooden door line can not be installed, so you need to install a false threshold here The threshold is 4 cm thick and the width is the width of the wall. Then, according to the entrance hole of the door hole, the thickness of the door sill is subtracted, and the final data is the width of the door; finally, the thickness of the wall is measured.

Note: When opening a door opening on a thin wall, in order to facilitate the placement of the door frame and ensure the stability of the wall, a threshold must be placed at the corner of the door or the side of the T-joint wall. The wall surface is not less than 120mm, and it should not be too long. The width is the same as the wall.

Facade width = door width + door sleeve width

Door width = door width + door fan clearance + door frame thickness + door frame solid plate thickness + door frame adjustment margin

1, the measurement of the door hole

The width of the door hole: horizontally measure the distance between the left and right of the door hole, select five or more measuring points for measurement, and the minimum value (minus the door frame adjustment margin) is the width of the door frame extension width

The height of the door hole: the distance between the upper and lower sides of the door hole is measured vertically. Three or more measuring points are selected for measurement. The minimum value (see door frame adjustment margin) is the height of the door frame.

Note: Pay attention to the ground treatment during the measurement process, and reserve the thickness of the floor decoration material for the required. Thickness of the wall of the door hole: measure the thickness of the wall horizontally. Select more than five measuring points to measure it. The maximum value is the thickness of the wall. If the wall needs to be decorated, the thickness of the door wall needs the thickness of the decorative material.

2, the measurement of the door leaf

Door leaf = inner space of the door frame - reserved gap

The width of the door leaf: measure the distance inside the door frame horizontally, and select more than five measuring points for measurement. The minimum value is (reduced clearance) is the door width.

Height of the door leaf: Vertically measure the distance inside the door frame, select more than three measuring points for measurement, and the minimum value (minus the reserved gap) is the door height.

Note: Pay attention to the ground treatment during the measurement process, and reserve the appropriate size for the required.

The height of the door leaf and the height of the door opening are 5-10mm, and the thickness of the door leaf is 38mm and 45mm. It must be matched with the door frame.

Conditions that must be met before the door is measured

1. The customer and the person in charge of construction must be on site;
2. The hydropower transformation and wall reconstruction must be completed;
3, the horizontal line is available, the kitchen wall, floor tiles need to be paved, the floor room needs to be leveled. The height of the wall, floor tiles and floor should be determined;
4. Determine whether the wall should be increased by the wall;
5. The measurement must be signed by the three parties.

Door measurement detail

1. The high demand is three times, and the results are measured in the order of left, middle and right.

2, pay attention to the order of the door and floor installation, it is recommended to install the floor after the door is installed.

1. After the ground treatment, it can be used for the construction of other projects. When the construction period is nearing the end, the floor and wooden door should be installed. Who is the first to install the wooden door and the floor? Let's analyze it. If you install the floor first, there are some problems that can't be solved.

2. The position of the buckle between the living room and the bedroom cannot be determined. The process requires that the buckle must be directly under the wooden door. After closing the door, the buckle cannot be seen inside or outside.

Precautions during door measurement

1. The door opening is required to complete the vertical and non-tilting of the wall, and the thickness of the left and right walls is uniform and on a vertical end surface.

2. The surveying personnel will propose the corresponding rectification requirements according to the actual measured hole size on the site. Please confirm the size of the production and installation of the product, and then carry out the rectification and construction by the customer. Note: Different series of doors have different structural dimensions. Pay attention to the boundary position of different materials (floor and floor, floor and masonry bead position) when laying on the ground. Avoid the appearance of two different materials on the floor where the door leaf falls.

3. If the thickness, width or height of the customer's blank wall does not match the standard combination size, the customer's construction team needs to construct the product before the finished door is installed. It can be reformed with sheet metal and brick material, such as adding /tick. Cut the wall, increase/lower the door opening, etc. Avoid the finished door can not be installed smoothly.

4. If there is a height difference between the hall and the kitchen and toilet floor, the size of the ground should be determined with the surveyor during the measurement and marked on the measurement sheet to prevent errors during installation. It is emphasized here that the horizontal level of the decoration is the only reference standard for the size of the ground and the actual height of the opening. Therefore, the horizontal line of the decoration must be clearly and accurately marked when measuring.

5, the finished door installation, the set plate and the hole installation end face need to have 10-25mm installation glue joint.

6. The ground crossing stone (also called the door stone) should be laid before the measurement. If the measurement is not completed, the size and method should be confirmed with the surveyor to avoid the dimensional deviation. It must be laid before installing the wooden door. Otherwise, the height of the door may be changed or the door gap may be too large.
