DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method of mounting external cladding in the form of single sheets on, for example, the walls of buildings, by using fixtures which prior to the final mounting consist of at least two main segments, a wall bracket and a horizontal positioning plate, and also guides which hold the actual facing sheets in place. The invention also relates to the actual fixture.
The invention has been especially developed for mounting and fixing heavier types of external cladding, eg. natural stone. The fixtures can be mounted on all kinds of bases, such as steel, plaster, concrete and wood. The invention can be used both during the construction of new buildings and during the rehabilitation of existing buildings.
Today various methods are used for fixing external cladding consisting of, for instance, natural stone. A common feature of most of these methods is, according to persons versed in the art, that they are time-consuming. This is due, in the main, to the fact that it is often necessary to align the wall body and it is difficult to put the brackets in the right position on the wall. It is usual to use a guide pin which is passed through the bracket and into the facing stone in order to hold said facing stone in place. Because of inaccurate positioning of the brackets, it is common to drill guide pin holes in the facing stone whilst at work in the scaffolding after distance measurements or position measurements have been taken. This requires adjustment work stone by stone. This is both time consuming and expensive. There are various types of rail systems, but a common feature of these is that they are extremely expensive. In some cases the plates are attached above/below the facing stone, and in other cases they are attached along the sides. This is dependent upon the design of the plates.
EP-A-0208229 discloses a fixing bracket designed for external cladding in the form of artificial or natural stone. This bracket is not adjustable in height so that when the fixing screws are mounted in the bearing wall, the height position of the bracket will be fixed. The horizontal segment of the bracket can however be adjusted normal on the wall by means of slots, whilst it can be adjusted parallel to the wall by means of yet another slot. The bracket is thus adjustable in two dimensions.
DE Auslegesschrift 1289289 also discloses a wall bracket for external cladding. The segment which supports the facing sheet is adjustable to a certain extent relative to the wall. This segment is also height adjustable, but the height adjustment is dependent upon the adjustment in the horizontal plane in a direction along the wall.
DE Offenlegungschrift 3611072 also teaches a fixture for external cladding. One embodiment is not height adjustable. It can however be adjusted in the horizontal plane both along the wall and at right angles to the wall, although the last-mentioned is done by means of teeth which do it step by step and not continuously. A second embodiment is height adjustable by means of a slot. In this case, the distance to the wall can also be adjusted step by step and the adjustment along the wall is carried out by means of a slot, but a support plate describes a circular arc on adjustment of this kind. With a fixture of this kind the guide pins will easily come out of linear alignment with other pins on corresponding brackets when an adjustment of this kind is carried out.
DE Offenlegungschrift 3910286 teaches yet another fixing bracket for external cladding. It is height adjustable via a slot in a plate. The actual support portion of the bracket is not adjustable in the direction that is at right angles to the wall or along the wall in the horizontal plane.
The brackets referred to above according to the state of the art are designed for use with the traditional method of fixing external cladding. I.e., that the brackets are mounted in succession as the facing sheets are mounted in place one by one.
That which especially characterizes the present method and fixture is that the mounting of the exte
