Abstract

The accommodation box is made of concrete, rigid plastic, compound cast mass and compound materials. The insert comprises an all-round frame, which at the bottom has two reinforcement thresholds, which present an application possibility for the window or door component to be installed and at the same time a location for the inner window sill. Integrated accommodation possibilities are provided for the incorporation of the roller blind shaft with internal shaft motor and the roller blind box cover, with corresponding dowel holes and fixtures nose formations together with a room-side extending plaster strip. The insert box is produced in different depths, heights and widths and for the different brickwork thicknesses, with and without front shells and for all window and outer door sizes.

Description

Window or exterior door insert with prefabricated roller shutter holder Box for electric shutters made of concrete, rigid plastic, composite casting compounds and composite materials, in particular for the shell of Apartment buildings.

It is known that such window or exterior door inserts with one prefabricated roller shutter receiving box (DE-GM 19 92 721), trades of Can combine external openings.

In the building shell area, these external openings such as windows, balcony and Patio doors of the living rooms individually or according to standard dimensions created. The planners often use this for cost reasons standardized windows and doors. The masonry creates the openings in the shell. It is at the opening itself and the top off save for the later assembly of the electric roller shutter. Also the consideration for the application of the interior window sill must be considered. In the planning of the architect and in the execution The contractor therefore makes decisions that the later Trades concern. There would be z. B. window or carpenter, roller shutters bauer, plasterer and stonemason, all trades that work together according to VOB work. Errors are human and less and less qualified personnel, they occur more and more frequently. Mistakes to avoid would be. For example, the openings may be too large or too small, the result is that post-mortem or must be bricked up. Windows are therefore usually only after the creation of the external clinker, because the view masonry is only binding. Also problems with plastering the Window reveals become very difficult and too large openings more expensive due to thicker plaster application, not to mention the Angularity and the elaborate setting of the corner protectors. At the Roller shutter builders always have difficult fastenings for the Hanging the cover box can be set, time consuming and costly intensive. The laying of the interior window sills can not in rare cases can only be done with additional masonry work, since Upper edge of parapet and lower edge of window groove too far from each other are removed. The window sills can also only be measured after the installation of the windows.

The problem is that by interlocking different ones Crafts groups and mistakes due to lack of coordination when creating and completing the openings, which arise can be corrected by corrections, which would however be avoidable. Also superficial, imprecise work of the craftsmen, ignorance of the  exact standard dimensions, all factors, the additional work and could cause unsatisfactory end results for windows and Exterior doors through prefabricated parts that do all of this in advance and take into account the coordination of the individual trades Form a combination, be completely excluded.

The problem can be solved with industrially prefabricated inserts that the have features listed in claim 1 can be solved.

The advantages achieved by the invention are that Insert boxes without previous knowledge, only after selecting the in the Ordered drawing specified dimensions and without much time be used. The stakes are then only with the wall plant network of the structure walled. The followers can be found on their trade matched upfront investments in advance that do their job combine and minimize. The stake includes, in each case Four continuous holes at the top for fastening the roller shutters shaft bracket. Also a nose for attaching the lower cover boards of the roller shutter box with clamping springs is on the right and left in front act. There are also three in the horizontal top part at the front and back through holes for dowel attachment of a construction slat for Attachment of the front roller shutter box cover provided. The actual cover plates of the roller shutter box are made of composite panels (wood / insulation board). Openings for the passage of the supply cable to the shaft motor are in the top right and on the left, depending on which side of the control switch is set. A protruding plaster strip on the corner of the window reveal / Room walls can make it unnecessary to attach corner protectors; it can simply be cleaned against the edge. Two lower ones Enabling reinforcement thresholds 1. the window can be on the after the threshold located on the outside and 2. the rear one Reinforcement threshold enables the windowsill to be securely placed on the the space between the two sleepers for receiving the laying mortar of the interior window sill. Disappear with door inserts this in the floor area. The top of the insert box serves the same timely as underlaying of the window or door lintel, which is therefore a smooth lintel base. The box can be in masonry width for masonry with external insulation and plaster, as well for masonry with insulation (e.g. mineral fiber wool) and facing clinker. With the latter, it is difficult anyway due to the window  of the high insulation thicknesses. A questioning of the Insert box in the insulation area eliminates this defect. The window or the patio door is fitted with special dowels between the window and Box securely attached. The size of the insert box allows for the shell work a safe and easy alignment; thereby save the follow-up works enormously in time, because they are expensive No more work. The more accurate the window or door, e.g. B. less than 1 cm all the way to the insert box, the less the night work. The resulting joint can be made with acrylic or the like be closed, if necessary with a cover strip.

The plastering of the window reveal could therefore be omitted. At most a fine filler would be necessary and the reveal could be painted, papered or tiled in bathrooms. The plaster, often a additional work step could be omitted. Also plastering up The upper edge of the inside reinforcement threshold would be cleaned Make it superfluous because the interior window sill is exactly at this point would hang up.

An advantageous embodiment of the invention is in claim 2 specified. The insert box can be in different depths be made so that it for all masonry thicknesses 17.5, 24 and 36 cm for supporting masonry with external insulation and plaster as well as in 24, 36 and 42 cm for masonry with insulation and clinker, boxes available. In addition, the inserts can be height and width can be manufactured variably so that they can be used for all windows and external doors Are available.

An embodiment is shown in the drawings and is in described below.

Show it:

The window and exterior door insert in drawing 1, number 1 shows the three dowel holes for attaching an auxiliary lath for attaching the front roller shutter box cover. Holes 1 a are intended for fastening the roller shutter shaft with an internal shaft motor and in 1 b there is a hole for the supply line to the motor, on the right and left, depending on the position of the control switch. At number 2 shows the fastening lugs for receiving the lower roller shutter box cover, on these lugs the cover can be fastened with clips. At the same time, this edge serves as a counter bearing and as a wind or dust break edge. 3 shows the outer, lower reinforcement threshold on which the window or door sits. Number 4 serves as a trough for receiving the installation mortar of the interior window sill.
