Description

Field of the invention

The The invention relates to a profile frame construction comprising a Substructure made of wood and a basic profile attached to the substructure is attached. Furthermore, the invention is a method of attachment a basic profile on a post or bolt profile made of wood described.

The composed of mullion and transom sections substructure and the basic profile together with the infill elements, such as Panels or glass panes, the basic elements of a profile frame construction. Profile frame constructions are e.g. Facade structures, such as vertical Facades, polygonal facades or glass roofs, or spatial structures.

State of technology

in the In the prior art, the substructure of a facade is often made a single component extruded from aluminum or steel or stainless steel can be roll formed. The integrally formed substructure here has a device for fixing facade screws on, which is usually designed as a screw, as well as attachment approaches for inner seals. At the Providing a substructure of metal is due to the high Production costs for a precise one Shaping is common in steel a two-piece construction is provided in which on a substructure a basic profile is applied. Consists of the substructure made of wood, so two-piece constructions are also proposed since in particular in the area of the screw channel a high strength is needed.

In known in the art are wood-aluminum profile frame constructions, in which on a substructure made of wood a basic profile Aluminum is screwed on. Such a profile frame construction But is technically complex, because to achieve a sufficient strength a large number of mounting screws must be provided. In the art one therefore always endeavored, fastening screws to use that reducing the number of attachment points Make basic profile possible per running meter.

presentation the invention

Of the Invention is based on the object, a profile frame construction to propose the type mentioned, with which such Profile frame constructions faster and thus more cost-effective let produce.

These Task is by a profile frame construction with the features of claim 1. Preferred embodiments follow from the rest Claims.

The Profile frame construction includes a wooden substructure and a basic profile, the punctiform fastened to the substructure with fastening elements, being used as fasteners nails or brackets are provided extending through the base profile extend into the material of the substructure.

The inventive profile frame construction thus uses fasteners between basic profile and substructure, which, individually, usually used forms of fasteners often even lower tensile forces can transfer the basic profile in the substructure as usual in the art fastening screws. This implies that more such nails or staples are to be provided as would be the case with wood screws as a fastener. Of the Advantage of the solution according to the invention exists but in that the nails or brackets can be driven in a very simple manner by e.g. compressed air operated setting tools for shooting used in magazines fasteners used come. Here is a departure from the current trend, fasteners to choose that a smaller number per unit length Basic profile is sufficient.

Accordingly, FIG the procedure for attaching a basic profile to a post or bar profile made of wood the steps on laying the basic profile on the mullion or transom profile, the placement of a setting device for Delivery of nails or Clamps on the basic profile and driving a nail or a staple through the base profile into the post or Bolt profile, wherein the steps of placing the setting tool on the basic profile and the driving in of a nail at different Positions on the basic profile according to the desired Strength be repeated.

According to a preferred embodiment of the invention, the basic profile is made of metal, aluminum being particularly preferably used. Alternatively, steel, galvanized steel, stainless steel or copper can be used. A base profile made of metal has an increased strength compared to the wood of the substructure, is weather-resistant and can also be manufactured with tight tolerances. Aluminum is particularly preferred because even complex shapes can be produced by the extrusion process. Alternatively, however, the basic profile of one of the other mentioned steel materials are roll formed.

alternative Is it possible, the basic profile also made of plastic such. glass fiber reinforced polyamide.

It is preferred to provide as fasteners nails whose diameter between 1.5mm and 5mm, preferably between 2.5mm and 3.5mm. This diameter range can on the one hand transmit relatively high forces, On the other hand, there is also the usual Wooden materials of the substructure no danger, that the material is blown up when driving in the nails and thus the desired Strength can not be produced.

Preferably is the shaft length the nails used as fasteners between 25mm and 150mm, Preferably, the shaft length is between 45mm and 90mm.

at the use of nails can different types are used. For example, the nails can be smooth or be sharp-grooved. Another alternative exists in that nails Can be nail screws, as are also available for use in magazines for suitable setting tools. Especially in the latter case the use of nail screws is preferred, the nails with a head with tool attack, preferably torx, to provide with it the nails can also be turned out of the substructure again. On that way the profile frame construction according to the invention make it demountable.

alternative on the use of nails as fasteners can also staples are used, that is, essentially of wire material shaped, U-shaped Fasteners whose wire diameter between 1.0mm and 3.0mm, preferred is about 2.0mm. Staples have the disadvantage over nails that their Position for attachment not just punctiform predetermine, but Also the orientation of the bracket itself has to be considered. The advantage a mounting bracket opposite a nail is that, depending on the shape of the nail head, The clip looks a little lower than the height of the substructure opposite surface of the basic profile extends as a nail, but at the same time due the shaping of a clip with one of the two attachment legs connecting bridge one good form-locking Connection made between the bracket and the base profile becomes.

At the Use of staples as fasteners are preferred Brackets are used, which have an element length between 50mm and 150mm have. Such element length provides sufficient Penetration depth in the wood of the substructure safe.

Either when using nails or brackets are made of steel, galvanized steel or stainless steel.

In the previous description was assumed to that for a profile frame construction uses either nails or staples become. This certainly represents the more realistic variant Nevertheless, it is conceivable that nails and clamps parallel to each other and combined in a single profile frame construction.

Preferably are produced in the basic profile holes or in another way Holes to Attaching the nails or brackets provided. By providing appropriate holes can be easily penetrated the basic profile and it can also predefined distances specified between the individually set nails or brackets become. Alternatively, however, the basic profile no such holes own and used for driving the nails or staples setting tool has sufficient power to nails or staples also through a steel or stainless steel base profile of usual thickness into the To collect substructure of wood.

Around To increase the processing speed, setting tools are preferably used, which have a Magazine for holding a large supply have on fasteners. When using nails these can for example spirally prefabricated be used in such a magazine. such, spiral pre-assembled nails are referred to as coil and are available for appropriate setting devices in the trade.

• (a) Auflegung des Grundprofils auf das Pfosten- oder Riegelprofil;
• (b) Aufsetzen eines Setzgerätes zur Abgabe von Nägeln oder Klammern auf das Grundprofil;
• (c) Eintreiben eines Nagels oder einer Klammer durch das Grundprofil hindurch in das Pfosten- oder Riegelprofil;
• (d) wiederholen der Schritte (b) und (c) an verschiedenen Positionen auf dem Grundprofil.

The method of attaching a base profile to a wooden post or bar profile comprises the steps of:

• (a) application of the basic profile on the mullion or transom profile;
• (b) placing a setting device for dispensing nails or staples on the base profile;
• (c) driving a nail or staple through the base profile into the post or latch profile;
• (d) repeating steps (b) and (c) at different positions on the base profile.

In this case, preferably in step (b), the setting device is placed on the base profile such that the delivered nail or the delivered clip can pass through holes in the base profile.

alternative Is it possible, that in step (c) the nail or clip is the material of the Basic profile permeates.

at the implementation the method is preferably a setting tool for nails used with a Magazine for holding a preferably spirally prefabricated Supply of nails provided is. When using brackets is a stapler for staples used that with a magazine for recording in a row Pre-assembled stock of nails is provided.

Short description the figures

following the invention will be purely by way of example with reference to the accompanying figures described in which:

1 shows a section through a profile frame construction according to the invention;

2 is a plan view of a fixed to a substructure basic profile; and

3 represents exemplary designs of the nails or staples used.

Ways to execute the invention

In The following figures are each with the same components the same reference numerals. Therefore, in each subsequent Figures on a detailed Description of the already explained Components are omitted.

1 shows a section perpendicular to the longitudinal extent of a substructure 10 a facade. At the substructure 10 it can be both a post and a bar. Accordingly, the cut proceeds 1 with a post in the horizontal direction and with a bolt in the vertical direction. Although in 1 a façade structure is shown, it should be clear that the profile frame construction generally comprises a vertical facade, polygon facade, glass roofs, but also other spatial structures in which the basic elements described below are present in the same way.

In the present case, there is the substructure 10 made of wood and is designed as a rectangular profile. On the substructure 10 are fasteners 20 of which in the illustration in 1 only the head is visible. The fastener serves to a basic profile 12 on the substructure 10 to fix.

In the 1 and 2 illustrated geometry of the basic profile 12 is only an example, in particular with respect to the shape of the illustrated screw channel 25 and the attachment approaches 27 for a one-piece or multi-part inner sealing strip 16 , In the present case, a one-piece inner seal strip is provided, which extends over the screw 25 extends. It should be clear, however, that in addition to the embodiment shown here with a single continuous inner seal 16 , Which also has a Sollrissstelle for cutting through the overlapping attachment in the transition region between posts and bars, other geometries, as well as multi-part inner seals in the same way are possible. The same applies to the special shape of the inner seal 16 with fastening lugs 17 for attaching an additional insulating body 14 in Glasfalzbereich between the filling elements shown here as insulating glass panes 18 ,

In 1 Also shown is a facade screw 24 in the screw 25 engages and a pressure bar 26 with the interposition of external seals 28 against the basic profile 12 clamps to the filling elements 18 to fix. The essential aspect of the invention is to attach the base profile on the wooden substructure. The basic profile 12 is preferably made of aluminum, but other suitable materials can alternatively be used, such as steel, galvanized steel, stainless steel, copper but also plastic such as glass fiber reinforced polyamide. The basic profile 12 is about the fasteners 20 punctiform on the substructure 10 made of wood. These can be used as fasteners nails or staples. Both nails and brackets are preferably made of steel, galvanized steel or stainless steel. As will be described in more detail below, the attachment is usually carried out with the aid of a setting tool with which the nails or staples can be driven through the base profile into the substructure in a relatively rapid sequence. The advantage of choosing the fasteners 20 as nails or staples is thus that this much faster than conventionally used screws in the substructure 10 can be introduced, which allows the installation of the basic profile on the substructure much faster and thus cheaper to perform.

In the 2 shown plan view of a fixed to a substructure basic profile is intended to illustrate different attachment alternatives. In this embodiment, there are various holes 22 in the basic profile, where on the right in the drawing plane, the holes 22 for the passage of individual nails 21 serve while drilling 22 are arranged on the left side in the drawing plane in pairs and at a predetermined distance from each other to the passage of the legs of a clip 19 to enable.

In the same way it is also possible, the basic profile 12 without corresponding holes 22 provide and penetrate the material of the base profile when driving the nails or staples. The advantage of drilling 22 is that according to the required strength of the connection between substructure and base profile of the hole spacing and thus the number of nails or staples per meter can be specified. Another advantage of the provision of holes is that the force required to drive in the fasteners is lower. When driving in brackets with too much force, there is a risk that deform the legs of the clip. For this reason, the embodiment without the provision of holes in the base profile is also preferably provided in connection with nails as fastening elements.

Of the Disadvantage of the embodiment with holes is that an exact positioning of a setting tool for driving in nails or parentheses is required.

In 3 are shown different types of nails and the basic shape of a clip 19 , The nails can be made smooth, as with the nail 21a is shown, or grooved according to example 21b be executed. As another alternative can also nail screws 21c be used. With regard to the shape of the head, the various embodiments shown on nails can each also be combined with different heads. The nail screws preferably have a head 23 which allows a tool attack. The nail diameters are between 1.5mm and 5mm and are preferably between 2.5mm and 3.5mm, while the shank length of the nails can be selected over a wider range between 25mm and 150mm. However, shaft lengths between 45mm and 90mm are preferred.

The brackets 19 preferably consist of a tapered at the ends of wire with a diameter between 1mm and 3mm, preferably by 2mm. The total length of the brackets is between 50mm and 150mm. Both the nails and the brackets are preferably driven by means of a nail device or stapler, which can be used as helical coils in a corresponding magazine of a nail-setting device when using nails. When using nail screws they are driven like a nail, but can be unscrewed like a screw.

at the use of nails as fasteners are preferably compressed air operated Stauchkopfnagelvorrichtungen used. When using staples can be used commercially available staplers, which are powerful enough to clamp up to the specified length of to collect up to 150mm. Even with corresponding staplers magazines are for recording a big one Number of brackets used to attach as quickly as possible in lengths of several meters to be installed basic profiles on wooden substructures to enable.

The Method for attaching a basic profile is performed by first the basic profile placed on the posts or bars and optionally temporary is fixed on it. Subsequently becomes a setting tool for delivery of nails or staples placed on the base profile and a nail or a staple through the base profile into the post or Bolt driven. Subsequently becomes the setting tool to the next Mounting position moved or, in a mechanical assembly the post or bar with the basic profile fixed on it, under move a stationary setting device and the process repeats. Depending on whether the fasteners should be driven by existing in the base profile holes or not, of course, must the positioning of the setting device with larger or performed less accuracy become.

Of the essential aspect of the invention is that by the provision of nails or brackets although fasteners are used, the depending on the design, even lower tensile forces on the basic profile in transfer the substructure can as previously used in facade construction wood screws. The advantage However, it is that according to the invention profile frame structures can be mounted very quickly, because using automated setting tools this with a corresponding operated high frequency of driving individual fasteners can be.
