The disclosure relates to building windows, more particularly to a frameless window installation assembly.
Referring to
However, it is difficult to conceal the outer holding member 922 of the window frame 92 during architectural design. In addition, the window frame 92 is made of metal material; the thermal insulation effect of this conventional window 9 is relatively poor due to the thermal conductivity of the metal frame portion 921.
Therefore, the object of the disclosure is to provide a frameless window installation assembly which provides a window apt to be concealed from view when mounted on the wall and has better thermal insulation effect.
According to the disclosure, a frameless window installation assembly is adapted to be mounted on a building wall. The frameless window installation assembly includes a window sheet unit, an inner bar holder, and an outer bar holder. The window sheet unit has an inside surface and an outside surface that are opposite to each other in an interior-exterior direction. The inner bar holder is made of metal, is disposed around a periphery of the inside surface of the window sheet unit, and is adapted to be secured to the building wall. The outer bar holder is made of metal, is disposed around a periphery of the outer side surface of the window sheet unit, is spaced apart from the inner bar holder, and is adapted to be secured to the building wall. The inner bar holder and the outer bar holder are not directly interconnected by a metal structure. The window sheet unit is secured between the outer bar holder and the inner bar holder.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
As shown in
The window sheet unit 1 includes two window sheets 11 juxtaposed with each other in the interior-exterior direction (D1), and a thermal insulation layer 12 disposed between the two window sheets 11. An inner one of the window sheets 11 has an inside surface 111 facing the interior of the building; an outer one of the window sheets 11 has an outside surface 112 facing the exterior of the building (i.e., the inside surface 111 and the outside surface 112 are opposite to each other in the interior-exterior direction (D1)). The inside and outside window sheets 11 are of equal size, and the thermal insulation layer 12 is disposed around and between peripheries of the two window sheets 11. In the first embodiment, the window sheets 11 are made of glass, but the window sheets 11 may be of other materials in other embodiments.
The inner bar holder 2 and the outer bar holder 3 are made of metal, are adapted to be secured to the installation surface 72 of the building wall 7, and are respectively disposed around the peripheries of the inside surface 111 and outside surface 112. The outer bar holder 3 and the inner bar holder 2 cooperatively define a channel (S), and the window sheet unit 1 has a peripheral portion that is received in the channel (S). The inner bar holder 2 and the outer bar holder 3 are not directly interconnected by a metal structure. In other words, no metal structure is provided to directly interconnect the inner bar holder 2 and the outer bar holder 3.
In the first embodiment, each of the inner bar holder 2 and the outer bar holder 3 is tubular and has a rectangular inner space. The tubular form minimizes the material cost and the weight. Moreover, the rectangular tubing is easy to handle and fits common situations. The shape and profile described herein are only for examples and should not be limited thereto. In addition, in the first embodiment, the tubular inner bar holder 2 and the outer bar holder 3 are filled with foam material in order to provide a better thermal insulation effect, but it may be filled with other materials or not filled.
The outer anchoring member 4 is adapted for extending from the outer bar holder 3 in a direction away from the window sheet unit 1 along the exterior-facing wall surface 71. In the first embodiment, the anchoring member 4 is welded to the outer bar holder member 3. In this way, the outer bar holder 3 and the anchoring member 4 can be fabricated separately and this facilitates the fabrication. However, the outer bar holder 3 and the anchoring member 4 may also be fixed to each other in other ways or formed integrally.
The fastener system 5 includes a plurality of first screws 51 which pass through the inner bar holder 2 and the installation surface 72 to fix into the building wall 7, and a plurality of second screws 52 which pass through the anchoring member 4 and the exterior-facing wall surface 71 to fix into the building wall 7. It should be noted that, in other embodiments, the inner bar holder 2 can be fixed to the building wall 7 in different ways, depending on actual conditions. For example, the first screws 51 may lock into the building wall 7 from the inside of the tubular inner bar holder 2.
The impervious unit 6 includes a impervious panel 61 that is adapted to extend through a gap between the inner bar holder 2 and the installation surface 72 of the building wall 7, a gap between the window sheet unit 1 and the installation surface 72, a gap between the outer bar holder 3 and the installation surface 72, and a gap between the exterior-facing wall surface 71 of the building wall 7 and the anchoring member 4. The impervious unit 6 further includes a plurality of airtight sealing strips 62 disposed respectively between the inside surface 111 and the inner bar holder 2 and between the outside surface 112 and the outer bar holder 3, a plurality of overlaid adhesive strips 63 each being disposed outer to a respective airtight sealing strip 62 and near the open end of the channel (S), and a caulk strip 64 disposed inner to the airtight sealing strips 62 in the channel (S) for filling the gap existing among the window sheet unit 1, the inner bar holder 2, the outer bar holder 3, and the impervious panel 61 or the installation surface 72.
As compared with the prior art, in the first embodiment, the outer bar holder 3 is not connected with the inner bar holder 2 through an integral metal structure. Therefore, in the aspect of appearance, a frameless effect can be produced when the outer bar holder 3 and the inner bar holder 2 are concealed from view, which is easier for architects to achieve. In the aspect of cost, the absence of integral metal structural connection between the inner bar holder 2 and the outer bar holder 3 can significantly reduce the material cost which in turn reduces the overall cost. Moreover, the thermal conduction will be reduced since there is no connection between the outer bar holder 3 and the inner bar holder 2 via thermal conductive structure, this will improve the thermal insulation effect of the embodiment.
Referring to
The second embodiment can achieve the same effect as that of the first embodiment. It is noted that the arrangement of the anchoring member 4 can be adjusted depending on the actual circumstances.
In summary, the frameless window installation assembly of the present disclosure provide the channel holder (S) for the window sheet unit 1, which is constituted by the inner bar holder 2 and the outer bar holder 3 which is not integrally connected with or in contact with the inner bar holder 2 by a metal structure, this makes it easy for architects to conceal the outer bar holder 3 and the inner bar holder 2 in order to create a frameless window appearance, and reduces the overall cost. Furthermore, it provides better thermal insulation effect.
