False sub-doors are divided into sub-doors and main doors. The main door can be opened and passed through. The sub-door is a decorative surface and cannot be opened. The surface is an extended facing and the inside is a solid wall.

The width of the decorative surface of the sub-door is about 1/2 the width of the main door.

Suitable for flat floors, hotel rooms, small offices and other places.

Extended study of common door installation techniques:

Process flow:

1) Play the thread and find the rules:

After the structural project has passed the inspection and acceptance by the supervision station, the door and window installation construction can be carried out. First, a large wire should be hung vertically from the top floor to check the accuracy of the window position and pop up the installation position on the wall. Line, process the structural edges that do not conform to the line

2) Determine the installation location of door and window frames:

Check the height of the window frame installation based on the indoor horizontal line of 100cm, and deal with the structural edges that do not conform to the line.

3) Determine the installation elevation:

Indoor and outdoor door frames should be installed according to the elevation of the drawing location. To ensure a solid installation, check in advance whether the number of pre-embedded wooden bricks is sufficient. For a 1.2m high doorway, two wooden bricks should be embedded on each side. For doorways with a height of 1.2 to 2m, 3 wooden bricks should be embedded on each side. For doorways with a height of 2 to 3m, 4 wooden bricks should be embedded on each side. Two 10cm long wooden bricks should be nailed to each wooden brick. of nails, flatten the nail caps, and drive them into the wooden door frame along the wood grain.

4) Installation template of sash and door frame:

Timber door frame installation should be carried out after floor work and wall construction

5) Make a sample:

Rotate the window sashInstall it on the window frame according to the requirements of the drawing. This process is called fan covering. For the quality of the cover fan, check the gap size, hardware installation position, size, model, and firmness according to the evaluation standards. If it meets the standard requirements, it will be used as a model. And use this as the acceptance criteria and basis.

6) Elastic wire installation of door and window frames:

The thickness of the plaster layer should be considered, and the installation position line should be drawn on the wall according to the size, elevation, position and opening direction of the door and window. The installation height of the window frame shall be based on the 50cm horizontal line on the wall. Use wooden wedges to temporarily fix the frame in the window opening. In order to ensure the straightness of the separated window frames, a small line should be pulled under the window frame to straighten it, and an iron level should be used. Introduce the flat line into the hole as a standard for erecting the frame, and then use a wire drop to correct the hanging straightness. Before installing the window frame, holes should be drilled in line with the position of the wooden bricks to facilitate nailing.

7) Door leaf installation:

① First make sure the door is open Direction and hardware model, installation position, cutting position and opening direction of the double door fan (usually the right fan is a cover fan)

② Check whether the size of the door is correct; whether the corners are square and whether there are any stray corners. Check the height of the door should be measured on the two vertical sides of the door. Check the width of the door should be measured on the upper, middle and lower points of the door. , and draw lines at the corresponding parts of the fan.

③ Place the door leaf against the frame and draw the corresponding size line. If the leaf is large, the larger part should be planed off according to the size of the frame. If the leaf is small, wooden strips should be tied, and the wooden strips should be tied to the hinge side. , glue it and nail it with nails. The nail caps should be flattened., 1~2mm into the frame along the wood grain;

④ After the first trimming The door leaf should be able to be stuffed into the entrance. After stuffing, use wooden wedges to support it and temporarily fix it. According to the width of the gap between the door leaf and the edge of the door, draw the second trimming line and mark the position of the hinge groove (distance from the door leaf). The upper and lower ends of each 1/10, and avoid the upper and lower heads). At the same time, attention should be paid to the smooth installation of the door and the leaf;

⑤ The door leaf is planed for the second time, and the gap Once the dimensions are appropriate, install the hinges. You should first use a thread to draw out the width of the hinge. According to the requirements of 1/10 of the upper and lower protrusions, determine the hinge installation edge. Measure the length of the hinge from the upper and lower edge lines inward. Pick the hinge groove and use the groove. Depth to adjust the door leaf and the frame after installation. Lines should be left when planing the hinge groove, and should not be too large or too deep;

⑥ After the hinge grooves are cut out, install the upper and lower hinges. During installation, you should first tighten a screw, then close the door and check whether the gap is suitable? Check whether the mouth and fan are flat. If there are no problems, tighten all the screws. Wood screws should be driven in 1/3 of the way in, and screwed in 2/3. If the wooden door is made of yellow pine or other hardwood, holes should be drilled before installation. The hole diameter of the hole should be 0.9 times the diameter of the wood screw, and the hole depth should be 0.9 times the diameter of the screw. 2/3, drill holes before tightening the screws to prevent the installation from cracking or breaking the screws.

⑦When installing a door leaf, you should measure the width of the door leaf with a ruler, and then determine the cutting depth of the center seam. If tongue and groove are used, the cutting depth and cutting direction of the joint should meet the requirements for locking, and then the surrounding areas should be planed to the exact size;

⑧ Hardware installation should comply with the requirements of the design drawings and must not be omitted. Generally, the height of door locks, bead bumpers, and handles at equal distances is 95 to 100 cm.

⑨ After the door leaf is opened, it is easy to touch the wall. In order to fix the position of the door leaf, a door bumper should be installed. For closed doors with special requirements, a door leaf opener should be installed.
