Corner wedge for press
Corner wedge for press + pin connection
I have explained to some extent how the internal profile gaps affect the corner joint wedge design regarding the frame design criteria. In this section, I will give information about how many types of corner joint methods there are and what should be taken into consideration during the design.
Profile Corner Joining Methods
Joining with press
Joining with pins or special screws.
Combining with compression
Joining with press
Notch slots
Frame press line
In the frame profile, the press lines do not change in the inner and outer profiles, this is the same in the mullion profiles. Since steel blind frame detail is generally used on the wall in our country, it is common to make a case from the mullion, which is more suitable for this detail. Since the inner and outer profiles are the same in the frame, a single measurement is sufficient for the press adjustment. This is not always the frame in sash profiles.
When designing the corner wedge, a small notch is cut from the profile flesh of the press blade and in order to squeeze the corners together and not leave any gaps, "notch slots" are created in the wedge. In this way, while the press blade passes into the slot with the aluminum, the corner 45s get very close to each other and do not leave any gaps. After this process, the profile notch will not come out again because it is stuck in the slot. Since the process is done in one go, it does not accept mistakes. It is necessary for the press blades to be in the correct position. The most important point in adjusting the press blades is the "A" measurement. It is useful to give a clear measurement of the "A" measurement during the corner wedge design. As a result, since we measure the press blades by looking at them with our eyes, we will not be able to choose dimensions smaller than millimeters.
There are those who make the notch slots in pairs on the corner wedge, but if there are double slots, generally the single slot, or rather the most suitable slot, is used. When a single slot is made, it is useful to place it in the most suitable place proportionally on the wedge and where the "A" measurement will be the clearest. The wedge should not stretch or warp when pressed, otherwise, if its profile tears its flesh, it will not have done the necessary compression job.
Wing press line is different
The press lines should be different in the inner and outer profiles of wing profiles. I will explain why in the "sash design criteria" section. Although there are applications in our country where the press lines of the inner and outer profiles of sash profiles are the same, I have seen that they encounter many problems, "the reason for doing this is to press the sash without disturbing the setting in the frame". Especially in these profiles, where there are much fewer problems with 12-15mm barriers, the problems start to become more obvious as the barrier grows, the barriers have to be enlarged according to market demands, so it is useful to know these problems in advance and make the design accordingly.
Sash press line is the same
In this picture, the press lines of the inner and outer profiles seem to be the same, there seems to be no problem. I will explain in more detail the "wing design criteria" regarding the problems that will be encountered.
