ABSTRACT:

The invention concerns the frontages of buildings, systems for constructing them and methods of constructing them.
“Lightweight” building frontages including lightweight frontage elements comprising a synthetic material cellular web are known per se. The frontage includes fixing members such as long horizontal rails joined to the building. Each frontage element is fixed to a plurality of rails supporting a plurality of frontage elements.
The drawback of this type of frontage is that the fixing members are difficult to transport, manipulate and install because they are large and heavy.
One aim of the invention is to provide a frontage that is easier to construct.
To achieve the above aim, in accordance with the invention a building frontage includes first frontage elements fixed to the building and each comprising a cellular core and second frontage elements, the first and second frontage elements are arranged in substantially the same plane and the second frontage elements are fixed only to the first frontage elements.
Accordingly, the fixing members are connected only to the first frontage elements. The shape and/or dimensions of the fixing members can therefore be modified to make them easier to manipulate. For example, their dimensions can be reduced until they are similar to or less than the dimensions of the first frontage elements.
Each second frontage element is advantageously fixed to four first frontage elements.
Accordingly, particularly reliable fixing of the second frontage elements to the first frontage elements is obtained.
The first frontage elements are advantageously disposed in parallel rows and the second frontage elements are disposed in rows parallel to the rows of first frontage elements.
The first frontage elements are advantageously fixed to floors of the building.
Each first frontage element is advantageously fixed to at least two floors at different levels.
Accordingly, particularly reliable fixing of the first frontage elements to the building is obtained.
Each first frontage element advantageously has a dimension in a direction perpendicular to the floors equal to n times a distance between like faces of two floors adjacent each other in that direction, n being an integer greater than or equal to 1.
Accordingly, first frontage elements and fixing members for fixing them to the building can be made which are identical to each other, which reduces their unit cost.
The frontage advantageously includes first members for fixing the first frontage elements to the building, the first fixing members having dimensions less than a greatest dimension of the first frontage elements.
Accordingly, handling of the first fixing members is facilitated.
Each first frontage element advantageously includes at least one rigid part fixed to the cellular core and the first fixing members are advantageously fixed to the rigid parts.
Accordingly, the mechanical strength of the first frontage elements is increased in the area where they are fixed to the building.
The frontage advantageously includes second members for fixing the second frontage elements to the first frontage elements and the second fixing members are advantageously fixed to the rigid parts.
Accordingly, the mechanical strength of the first frontage elements is increased in the area where the second frontage elements are fixed.
Each first fixing member advantageously includes means for adjusting an angular position of the first fixing member relative to a face of the building in at least one direction.
Accordingly, the fixing member can easily be fixed in a position near the required position.
The adjuster means are advantageously adapted to enable adjustment of the angular position of the first fixing member relative to the face of the building in two mutually perpendicular directions.
Accordingly, the first fixing member can be fixed more accurately.
The adjuster means advantageously include at least one screw-threaded housing in the first fixing member and at least one screw engaged therein, the first fixing member advantageously has two contact portions disposed to form a triangle with the screw and the contact portions and the screw are advantageously adapted to come into contact with the face of the building.
The contact portions advantageously comprise two screws engaged in second and third screw-threaded housings of the first fixing member.
The first fixing member advantageously further includes attachment parts for rigidly fixing the first fixing member to the building.
Accordingly, the function of adjusting the position and the function of fixing to the building are associated with separate parts, so that the parts can be better adapted to their respective functions.
The frontage advantageously further includes components fixed to at least some of the first and second frontage elements and lying in the plane of the first and second frontage elements.
Accordingly, there is no need to fix the components directly to the building, which can be laborious.
The invention also provides a system for constructing a building frontage including first elements comprising a cellular core and adapted to be fixed to a building and second elements, characterized in that it includes means for fixing the second elements to the first elements with the first and second elements in the same plane.
This system is used to construct the frontage in accordance with the invention.
The invention further provides a method of constructing a building frontage using first elements including a cellular core and second elements, in which method the first elements are fixed to the building and the first and second elements are disposed in the same plane and the second elements are fixed to the first elements.
This method is used to construct the frontage in accordance with the invention.
