ABSTRACT:
FIELD OF THE INVENTION
The present invention involves the industrial production of a series of aluminum profiles for the construction of curtain walls with suspended glassed panels.
BACKGROUND OF THE INVENTION
The structure and shape of the frame of the curtain walls manufactured today in Greece and internationally are based on the traditional structure of the frame with a grid of vertical beams. The vertical beams extend across all the height of the curtain wall as continuous beams. Small horizontal beams transverse and are positioned between the vertical ones. The glassed panels are placed onto this grid in contact both with the vertical and the horizontal elements, and are supported by it.
This structure of the frame has several problems and weaknesses, mainly concerning thermal expansion, antiseismic properties, tightness, safety and operation of the windows, strength and durability of the sealing materials, the general construction cost, etc.
SUMMARY OF THE INVENTION
The above problems and weaknesses are addressed efficiently with the construction of curtain walls with suspended glassed panels, to which the present invention relates.
The objects of the present invention are basically obtained by a curtain wall of a predetermined height, comprising prefabricated glassed panels, and a frame having only horizontal beams into which the glassed panels are placed for supporting the glassed panels, without continuous vertical beams existing along the height of the curtain wall on a building with multiple floors.
With this invention, the elements of the glasses—glassed panels, prefabricated at the plant, are placed onto the frame of the curtain wall, and are suspended only from the horizontal beams of the frame along their whole length. The glassed panels do not touch the vertical beams. The vertical beams only support the horizontal beams onto the slabs of the floors of the building.
Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses preferred embodiments of the present invention.
