Description

The invention relates to a window frame with a window for a basement room. The like. Made of plastic consists, which has a substantially uniform wall thickness, which forms as permanent formwork for the window opening, and in its side parts as well has projections in the upper transverse part for the installation of the window, which protrude into the opening and through to the outside open U-shaped gutters are formed.

It is known to form a basement window reveal that a basement window frame as a lost Formwork is used.

From DE-Gbm 74 20414 a cover made of plastic is known, which, however, due to its small wall thickness, cannot withstand the formwork pressure without major deformations. In addition, there is no guarantee that this window frame will have a permanent connection with the concrete over its entire circumference comes in.

The invention is therefore based on the object of creating a window frame of the type described above which is able to withstand the formwork pressure without deformation and which is firmly connected to the masonry.

The invention solves this problem in a window frame of the type described at the outset in that Longitudinal metal rails are embedded in the parts of the garment, with part of their cross-section protrude outwards from the garment.

But in order to establish a secure connection with the Mau in the area of the relatively flat parts of the garment The metal rails are provided to achieve the work or the surrounding concrete. Overall can in this way keep the wall thickness sufficiently small, which in turn reduces the overall weight is, which facilitates the installation and of course also keeps the manufacturing costs low

Appropriate refinements of the invention are the subject matter of the subclaims. In particular, will the cohesion of the garment during manufacture

ίο Individual parts then improved when the metal rails are each connected to form a frame, for example, the end parts of the rails are connected at the corners by spot welding.

In the drawing are some exemplary embodiments

is the invention shown schematically and in the following explained in more detail It shows

F i g. 1 shows a vertical section through the lower one Part of a window frame with a window,

2 shows a section corresponding to the illustration

the F i g. 1 through the upper part of a window frame with a window,

3 shows the partial representation of a horizontal Section of the window frame with window according to FIGS. 1 and 2,

F i g. 4 shows a corner connection for the Execution example! according to the F i g. 1 to 3.

F i g. 5 shows a modified embodiment and application example similar to that according to FIG. 2 and 6 shows the partial representation of a vertical Section through a window wall with a window of another exemplary embodiment.

The in the F i g. 1 to 4 shown window frames 1 consists essentially of four parts, namely the lintel 2, the side parts 3 and 4, which are symmetrical / uein are formed other and the window sill 5.

The training of the side parts 3, 4 and the lintel 2 largely agree. These parts of the garment 1 essentially consist of flat surfaces 25 on the outside of the window and "'äenen surfaces 26 on the inside of the respective window. The surfaces 25.26 can make a small acute angle to the Fensier occupy the mid-plane to the production process from the plastic to be processed to facilitate.

In each case between the flat surfaces 25, 26 are the

formed in cross-section U-shaped projections t2,13,14. These U-shaped projections 12, 13, 14 each consist of the legs 27 and 28 and the web 15. The parts 27, 28 and 15 delimit the recess 6 and it is clear that, for example, when setting in concrete the

so the garment 1 the concrete fills the recess 6 and thereby gives the projections 12, 13, 1 * great stability.

Note that on the outside of the window the projections 12, 13, 14 each have a stop 16, which also has a U-shaped cross-section. In this way, everyone owns the Projections 12, 13, 14 two stop surfaces, and / was the stop surface 29 in the area of the leg 28 and the stop surface 30 of the stop 16.

In the web 15 of the projection 12 is a blind hole 17 is provided, in which the pin 31 can engage. The pin 31 holds the frame 34 of the by means of the clamp 32 Steel cellar window 35, which is still held on the bench 5 by means of the clamp 33. The fastening The screw of the clamp 33 is denoted by 36.

It is clear that in this way a basement window can be fastened quickly in the garment 1 Only a few clamps 33 need to be installed using the screws 36

animals.

The construction of the bench 5 differs from the design of the side parts 3, 4 or the lintel 2. she consists, as is known per se, of the inclined outer and inner parts 37 and 38 with a flat central part 5 39. A step 40 is provided between the middle part 39 and the outer part 37.

All four parts of the Gewär.des 1 have on the dem Brickwork facing outside the Meiallschienen 7. These rails 7 consist of the two sides 9 and 10, with the leg 9 in the plastic material the garment parts is embedded, while the leg 10 protrudes outward. Both legs 9.10 can have recesses ΐ 1, the better Serve anchoring both in the plastic and in the masonry. The wall thickness of the plastic of the garment parts in the area of the rails 7 corresponds approximately inside and outside of the embedded legs 9 the remaining wall thickness.

As a rule, it is advisable to manufacture the individual parts of the garment 1 separately. When it comes to shaping of the plastic parts, care should be taken to create suitable connecting surfaces 8 that go through in the miter direction extending parts 41,42 are obtained. These parts 41, 42 also delimit the depressions 6.

The ends of the rails 7 are also connected to one another by spot welds 44, see above that frame-like structures arise, which result in high stability.

The embodiment according to FIGS. 1 to 5 shows the installation of a steel window of the usual dimensions. In the variant according to FIG. 6 is in the same Walls a window frame 51 made of wood or plastic is provided for which the abutment surface 30 and the blind hole 17 are used.

The lower spar 52 is fixed to the bench 5 of the drapery 1 by means of the fastening screw 53.
