one. The definition of the hanging window refers to the window where the rotating shaft is mounted on the right and left and can be rotated along the shaft. Whereas the rotating shaft is vertically mounted, the window that can be rotated along the shaft strictly refers to the vertical window. The two are slightly different but the principle is the same. The following is for convenience of description, collectively referred to as the hanging window.
two. The history of hanging windows first appeared in Europe, sunroofs or roof windows that could not be reached by warehouse or factory personnel, and can be opened and closed with a long hook, and no other attachments are required (so now there is still part of the skylight in the form of suspension In the past, due to continuous development, mid-hung windows have undergone great changes, and their characteristics are complex material types, unique hardware, and complicated processing, because these difficulties make many manufacturers The owner was discouraged, but because the suspended window itself can create a smooth and massive air circulation in the open state, it is recommended by some architects for windows with the best ventilation in the same area:
three. Hardware to discuss the hanging window, it is inevitable to understand the key components: in the suspension axis.
Taking Savoy Hardware as an example, the dimensions of the middle suspension axis are as follows:
Salvao suspension shafts are made of aluminum alloy and nylon, and have hexagonal screws that adjust the friction. Compared with the old middle suspension shaft, this suspension shaft is more securely mounted and can cooperate well with the European standard C slot, so it can solve the problem of multi-point locks that couldn't be solved by the old suspension shaft (usually old The window is a single point seven-word handle. This point will be explained in detail below.
four. The profile of the suspension axis in profile section is more complex than the general window type. Take the following figure as an example. Let's specifically understand a typical mid-hang window section:
The hanging window profile has more transition material than the general opening form profile, and its function is that the middle suspension axis is bounded, and after being turned over respectively, it is connected with the frame material and the fan material to form the different opening modes of the inner opening and the outer opening. The dimensions of B and A in the figure correspond to the B and A of the middle suspension axis. The middle suspension axis can be directly snapped into the frame and the sash profile slot, which is easy to install. Therefore, the transition material should have centerline symmetry, that is, the transition material and the frame, or the fan should be turned over and connected afterwards, but the centerline should be the same, and the hardware notch and the strip lap seal should be taken into account.
At the same time, the fan material is designed with double slots so that the transmission rod can avoid the middle suspension shaft and complete the transmission of the multi-point lock.
Because of the excessive processing of the transition material profiles of the suspended shaft section in the installation of the mid-hung window, multiple channels of seals have been designed to enhance the tightness of the entire window, and in particular, the unique central tape has different design shapes. But its basic function is to complete the lap and ensure the seal.
Fives. The frame and fan processing of the hanging window in the process are the same as those of the basic casement window, and will not be discussed here. The processing difficulty is mainly concentrated in the transitional material installation in the suspended axis part: too little processing, the middle suspension axis is not good to install and open the middle suspension axis will interfere with the profile; too much processing is easy to leak leakage, combined with the previous article The specific dimensions of the suspended shaft and the transition material can be drawn as follows:
The processing size 33mm is determined by the size of the suspension axis itself, and 29mm is determined by the specific transition material.
six. If the multi-point lock is not large in area, at the same time, the sealability requirements are not high, and the suspension can be used as a handle and wind bracing to seal the dots.
However, when the window area is large enough and the sealing requirement is high, the single-point seal is obviously not enough. At this time, a multi-point lock hardware system is very necessary. One of the key points of the multi-point lock of the hanging window is how to avoid the middle suspension axis and form a locking system that takes care of both sides. This is achieved through the double slots on the fan and the processed drive bar below:
The aim of the milled holes is to avoid installing the screws in the suspension shaft.
The drive bar is driven at the outer slot of the double slot of the fan profile, and the position of the suspension shaft close to the middle is disconnected. The drive bar shown in the above figure on the inner slot of the double slot completes the connection and forms a linkage.
It should be noted that the reason for using a two-way actuator instead of a one-way actuator (such as a T-piece, a one-way transmission box, etc.) is that the use of a one-way actuator causes the entire mid-hung window to be clockwise or counterclockwise. In the direction of force, the window is easily deformed.
Seven. Summary In summary, compared with other window types, the material, processing and hardware configuration of the suspended window must be more complicated. However, in the actual process, if handled properly and avoid weaknesses, it may be a unique window type.
