Directly connect to door frame
The above is the most common method of straight-jointed door frames. The general precautions are as follows:
1. The material thickness is recommended to be 1.2 thick (the actual thickness shall not be less than 1.08)
2. It is necessary to use vertical materials to close the door head and horizontal materials.
3. Note that the base must be about 5mm smaller than the edge size of the door frame to ensure sufficient space for installation and gluing.
4. The width of the door head board should be slightly smaller than the width of the vertical material by 1-2 mm, so that the closing is beautiful.
5. It is generally not recommended to use glue to close the inner corners of the door head board and the vertical panel, which is both beautiful and can test the installation quality of the door frame.
45° splicing door frame
The above is the most common 45° splicing door frame method. The general precautions are as follows:
1) The material thickness is recommended to be 1.2 thick (the actual thickness shall not be less than 1.08).
2) Note that there should be no misalignment at the diagonal point, and the welding point must be processed in a hidden position.
3) Note that the base layer must be about 5mm smaller than the edge size of the door frame to ensure sufficient space for installation and gluing.
4) It is generally not recommended to use glue to close the inner corners where the door head board and the vertical panel meet, which is both beautiful and can test the installation quality of the door frame.
Better splicing angle
Poor quality
▲The installation quality is poor, and the internal corners are glued to cover the defects. It is not recommended to use
Conventional practice
The conventional method of making a door frame with a stopper is shown in the figure above. The disadvantages of this method are:
1 It is difficult to insert it when the base is not accurate;
2 The size cannot be adjusted. If the base of the door opening changes, the size of the door frame cannot be changed.
3 The processing is complicated, and there is a risk of deformation during transportation when the size is large.
It is recommended to use the method shown in the figure above. The advantages of this method are:
1) When the base is inaccurate, it can be effectively resolved through structural decomposition.
2) The door frame width can be adjusted in a small range to adapt to changes on the construction site.
3) The size decomposition reduces the processing difficulty and deformation risk.
▲Note that the two boards must be kept horizontal during installation, and the base of the second gusset plate must be accurate.
Elevator door frame
General precautions are as follows:
1. The material thickness is recommended to be 1.5 thick (the actual thickness shall not be less than 1.38).
2. The width of the door headboard should be smaller than the width of the inner breadboard, so that the closing will be beautiful.
3. Note that the base must be about 5mm smaller than the edge size of the door frame to ensure sufficient space for installation and gluing.
Generally, it is not recommended to use glue to close the inner corners where the door headboard and the vertical breadboard meet, which is both beautiful and can test the installation quality of the door frame.
Node diagram of the door frame side panel structure decomposition
A part of the door cover panel is blocked and belongs to the invisible area, but it should be included in the final settlement, which causes material waste.
It is recommended to optimize the structure, as shown in the following figure:
The above nodes can effectively solve the problem of wasting invisible area in our conventional door frame production. At the same time, the edge card line can have a variety of changes, which is both beautiful and unified in structure.
