FR2620761A1 - Semi-finished product, notably for dressing openings in masonry - Google Patents

Abstract

The unit consists of an angular section 21 in fibre cement concrete stuck for example to the jamb of a window 111 and level with the adjacent external face 112 of the masonry wall 11. This section includes one wing 211 and one wing 212. Application in construction.

Description

 The invention relates to a semi-finished product, in particular for covering masonry bays.

The masonry bays are fitted with wooden or sheet metal cladding for visual reasons, but also to protect the masonry from the weather
Window sills and sills are also dressed the same way. The pre-cut claddings are fixed to the masonry by screws, nails or the like. The external claddings in wood or sheet metal must be painted periodically if one wants to avoid phenomena of corrosion and crumbling.
Starting from the state of the prior art which has just been mentioned, the invention responds in the first place to a need for an inexpensive material requiring no maintenance for the dressing of masonry bays or the like, that it is also possible to set up easily
This object is produced according to the invention by a cement and fiber concrete angle offered in the form of a semi-finished product or a product by the meter. Such a material is comparatively inexpensive, is also weatherproof, requires almost no maintenance and can easily be fixed to masonry, for example by gluing.

 The product can be available on a large scale according to needs in different forms such as profiles with branches of the same width on the one hand and profiles with one branch having a greater width than the other on the other hand , as well as in the form of right angle angles on the one hand and in the form of obtuse angle angles on the other hand, and also in the form of profiles of which one branch is thicker than the other. In the latter case, the thicker branch may in particular have on the inner side a recess starting from its front face.

The semi-finished product according to the invention is particularly suitable for covering and / or covering masonry bays and therefore also window sills and sills. At the level of the masonry bays this product can then be used directly for the manufacture of the frame
The sound insulation of this new frame profile demonstrates its effectiveness in the implementation in connection with interior doors.

The invention will be better understood in the description which follows with the aid of a few exemplary embodiments represented schematically in the appended drawing, in which
Fig.l is a section showing an angle in cement concrete and fibers that can be fixed on the jamb of a window
Fig.2 is a representation similar to Figure 1 showing a modified angle for a door frame
Fig.3 is a section showing an angle in concrete of cement and fibers associated with a window sill.

 The trim profile 21 at right angles, made of cement concrete and fibers, shown in Figure 1 is glued to the window jamb 111 and at the adjacent exterior wall 112 of the masonry 11. The reference 31 designates the corresponding vertical branch of a window frame incorporated in bay 12 of the masonry. In this example, the two edges or wings 211 and 212 of the angle iron or of the right angle profile 21 have substantially the same width and the same thickness, and the outer edges of the wings 211 and 212 are chamfered.

 According to FIG. 2, the branch 211 ′ of the angle iron 21 ′ which comes to bear against the jamb, has a recess 213 in which the branch of a door frame 32 also engages in cement concrete and fibers which can be fixed from the inside on the masonry.

Both the covering 21 'and the frame 32 are bonded to the masonry. The door to be mounted in this masonry bay bears the mark 31 ′. In this second example, the branch or wing 211 ′ of the angle iron 21 ′ is substantially wider and thicker than the other branch or wing of this angle iron covering or covering 21 ', and the outer edge of this other branch or wing is chamfered.

 The trim profile 22 for the window sill 12 shown in FIG. 3 has an obtuse angle corresponding to the inclination of the window sill 12.

In this third example, the upper branch
Su profile 22 which is adjacent to the window and inclined on the window sill 12 is of greater width but of less thickness than the other branch or wing, in the lower position and substantially vertical against
The external face of the masonry, and the external edge coman to the two branches is chamfered.
