NL1033607C2 - Preservation of wooden structural profiles screens against weather influence and prevents spread of dry rot in connection with renewal of wooden window frames, where construction is still intact - Google Patents

Abstract

Preservation of wooden structural profiles screens against weather influence and prevents spread of dry rot in connection with renewal of wooden window frames, where the construction is still intact. The profiles are provided with a special profiling and are preserved with acetic acid anhydride in order to guarantee a life length of a minimum of 20 years. The wooden profiles have notches cut on the rear side at the position of the width and to accurate dimensions. Traditional wood working remains possible.

Description

Structure

The invention relates to a structure at least comprising wooden structural parts that are exposed to weather influences.

Such a structure is generally known. The structure is generally composed of a combination of concrete, stone, wood and plastic, whereby the wood is generally used for window frames or parts of the facade. The advantage of using wood is that it has a good insulating effect and a warm appearance. The disadvantage of wood in buildings, however, is that it requires measures that serve to protect the wood in order to prevent its rot. To this end, it is customary to provide the wood with one or more layers of paint. However, this is physically problematic since paint can have a sealing effect, which in combination with incorrect details in building parts and connections results in moisture penetration and, as a result, promotes wood rot. Sealing layers of paint and other detailing errors prevent ventilation, which is crucial for the prevention of wood rot.

The object of the invention is to provide a solution to this problem, wherein optimum ventilation requirements can be provided for the wooden components used, while nevertheless also providing optimum protection against weather influences, moisture penetration is prevented, the natural surface structure of wood is not affected and the processing fits in with the daily routine actions of a carpenter. It is therefore an object of the invention to maximize the advantages of wood as a structural component while avoiding the associated disadvantages.

To that end, the structure according to the invention is characterized in that wooden cladding parts are arranged on the wooden structural parts with a ventilating space between the wooden structural parts and the wooden cladding parts which shield the wooden structural parts from the weather influences. Advantageously, the wooden covering parts are preserved in process with acetic anhydride and provided with grooves at the rear, which serve as guide grooves for tools and reduce the wood thickness very locally such that the covering parts can be narrowed in the longitudinal direction with a sharp knife. With this provision, the inventor aims to reduce the number of different profiles, to be able to supply standard profiles from stock and to simplify the processability during application.

It is preferred that the wooden structural parts are at least partially free of paintwork and that the preserved wooden covering parts are arranged directly on the bare wooden structural parts. In this invention form the invention lends itself in particular to use on the damaged wooden structural parts, which have been sufficiently stripped of the old layers of paint for a good adhesion of the joints and sufficient ventilation for the drying of the wooden structural parts. The connection is then preferably provided by sealants, neoprene spacers and adhesive tape, which serves as a spacer between the wooden structural members and the wooden cladding members. If the profile is installed without a ventilating air cavity, it will be attached mechanically.

The invention will now be further elucidated with reference to drawings, in which;

Details 1 to 4 show the profiles. The black areas are saw cuts. On the basis of these notches, the profiles can easily be cut to the width to be applied.

Advantages of this construction are that, in addition to the advantages of easy processing and known material, the wooden coverings have the same physical properties for the carpenters as the wooden structural parts. The profiles are relatively inexpensive to produce in the factory, relatively inexpensive to apply to the work, relatively inexpensive to keep in stock (limited stock) and relatively cheap to purchase. This makes the product accessible to everyone, no specially trained practitioners are required and the product is elevated to general applicability for recognized repair companies.

30 Detail A, side glass interior glazing single glass. The profiles are applied on the outside, glazing is applied on the inside of the frame and fixed with cavity-free glass battens.

Detail B, side and middle pillar exterior glazing single glass. The front of the 3 frame is covered with ventilation. The edges of the frame are cavity-free (fixed with a nail or screw) / so that glass repair can be carried out without damage to the ventilating construction. The profiles can easily be brought to the correct width using the 5 notches on the back.

The edge rounding can (with a cut profile) be applied in the work by sanding, planing or milling. The wood grain is preserved.

Detail C, calf exterior glazing single glass. Top and front of the calf 10 are ventilated with the profiles.

Detail D, lower and upper sill outer glazing single glass. The front and top sides are coated with the profiles in a vertical fashion. The day side of the top sill is covered without a cavity (fixed with nail or screw), whereby glass repair can be carried out without damage to the ventilating construction.

Detail E, sill exterior glazing single glass (different format). Description as detail D.

Detail F, detail horizontal cross section between post insulating glass outer glazing. The profiles are provided with ventilation on the outside. The detail of connection profiles on swing windows is shown.

Detail G, detail horizontal cross section side post insulation glass inner glazing. The profiles are applied on the outside, glazing is applied on the inside of the frame and secured with cavity-free glass slats.

Detail H, detail vertical section side post insulating glass inner glazing.

A detail of a partially lined frame. The exact details and method of covering are determined in advance on the basis of the state in which the frame is located. Depending on the results, it is determined which parts are to be coated.

Detail I, detail horizontal sectional side and intermediate post exterior glazing. Detail of external glazing with hinged windows. The swing angle of the windows must be taken into account. In many cases, covering the day edges will not be necessary, since the weather influences on these planes are limited.
