Description

Territory of invention

The The invention relates to a profile frame construction comprising a Substructure made of wood and a basic profile, punctiform with Fixing elements is attached to the substructure. Farther The invention relates to a guide device for driving in nails in such a profile frame construction.

The composed of mullion and transom sections substructure and a basic profile together with infill elements, such as panels or glass panes, the basic elements of a profile frame construction.

Profile frame construction are e.g. Facade constructions such as vertical facades, polygon 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. Further points the substructure also attachment approaches for inner sealing strips. When providing a metal substructure is due to the high production costs for a precise one Shaping is common in steel a two-piece construction provided, on which a substructure a basic profile is applied. Consists of the substructure made of wood, so also two-part constructions are proposed in particular in the area of the screw channel a high strength needed which a wood-based material can not afford.

In The technology is often wood-aluminum profile frame constructions have become known in which on a substructure of wood a basic aluminum profile is screwed on. Such But profile frame construction is technically complex because a large number to achieve sufficient strength must be provided by fastening screws. In the art was one therefore always strives to use mounting screws, the a reduction in the number of attachment points per running Meter basic profile possible do.

Out the German utility model 20 2005 005 795.9 is a profile frame construction known to be on a post or Bolt profile made of wood a basic profile using nails or Brackets is applied. The on both sides of the screw arranged nails are parallel to each other and parallel to the longitudinal as well as Transverse axis of the wood driven into the substructure. The There is a risk of a nail splitting the wood. This diminishes not only the strength of the connection, but can lead to serious damage when Moisture can enter the gap. Furthermore, in substructures, the are dimensioned such that the edge distance of the nail is small, the danger is given to nails Outside can sign off.

presentation the invention

Of the Invention is based on the object, a profile frame construction the type mentioned at the beginning with an improved nail connection to propose between substructure and basic profile. Farther the invention has the object to provide a guide device, the in conjunction with a nailing machine a faster and cheaper Producing the profile frame construction according to the invention allowed.

This Task is by a profile frame construction with the features of claim 1 and a guide device solved with the features of claim 12. Preferred embodiments follow from the rest Claims.

The Profile frame construction includes a wooden substructure and a basic profile, the punctiform is attached to the substructure with fasteners. The basic profile has a screw, in the mounting screws can be screwed. The fasteners are nails, which through the base profile into the wood material of the substructure extend. The nails are at an angle to the Median plane passing through the longitudinal axes the fixing screws is defined. In other words, one runs Center plane through the profile frame construction, centered through the screw channel as well as the underlying substructure extends from wood. At this median plane, the nails run in one Angle. Furthermore, the nails run so that they are in the Substructure with increasing distance from the base profile facing Approximate the side of the midplane substructure. In other words the nails on both sides of the screw channel so driven that they are in a sectional view considered to run towards each other.

The solution according to the invention is advantageous in that the driving in of the nails at an angle reduces the risk that nails will edge off at a small margin stand out. Another advantage is that the angular driving in of the nails reduces the risk that the nails will split the wood of the substructure.

To a preferred embodiment of Invention extend the nails at an angle between 3 ° and 10 °, preferably at an angle of about 5 ° to Midplane. These angular ranges have proven to be particularly advantageous proved to be at a correspondingly large penetration depth into the substructure to achieve the above benefits. After a preferred embodiment The invention consists of the basic profile of metal, in particular Aluminum is used. Alternatively, steel, galvanized Steel, stainless steel or copper can be used. A basic profile Metal has one opposite The wood of the substructure increased strength, is weather resistant and can be also manufactured with tight tolerances. Aluminum is particularly preferred because even complex shapes can be produced in the extrusion process. Alternatively, however, the basic profile of a steel material be roll formed.

alternative Is it possible, also to manufacture the basic profile from plastic, such as 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 usual Wooden materials of the substructure only a slight risk that the material is blown up when driving in the nails and thus the desired Strength can not be produced and moisture in the gap formed can penetrate. The shaft lengths The nails used as fasteners can be in a wide range vary between 25mm and 150mm, but are preferred between 45mm and 90mm.

It can used different types of nails become. The nails can for example, be smooth or be sharp-grooved. Another alternative is that the nails Can be nail screws, as are also available for use in magazines for suitable setting tools. 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 be turned out of the substructure again. To this Way lets the profile frame construction according to the invention make it demountable. The nails are preferably used made of steel, galvanized steel or stainless steel.

Preferably are produced in the basic profile holes or in another way Through openings for the Provided nails. By providing appropriate holes can easily The basic profile can be penetrated and there can also be predefined distances between the individual nails to be set be specified. Alternatively, however, the basic profile no have such holes and used for driving the nails Setting tool one have sufficient penetrating power to nails also by a steel or Standard stainless steel base profile Thickness through driving into the substructure of wood.

Around To increase the processing speed, setting tools are preferably used, which have a Magazine for holding a large supply on nails feature. The nails can for example spirally prefabricated be used in such a magazine. Such spirally prefabricated Become nails referred to as coil and are for corresponding setting tools available in the stores.

The Guide device according to the invention for Driving in nails in a profile frame construction of the type according to the invention includes a guide head with a first recess that is dimensioned to with at least a first contact surface this recess flush on a first outer wall be applied to the screw channel and at least one implementation for nails, the is inclined at an angle to the first contact surface. The implementation is in this case dimensioned so that a netting by this setting tool through the guide head can be driven. The guide head thus serves for a the nail guide and secondly, in coordination with the geometry of the profile frame construction according to the invention, a precise positioning of the nail to be driven.

The guide means preferably comprises a fastening device for attachment of a Nail setter. Thus, the guide device itself becomes part the jig and can be used accordingly as a guide head of the same become. The fastening device can be different, the person skilled in the art Species be designed.

According to a preferred embodiment of the invention, the guide head of the guide device is designed so that the first recess has a second contact surface which is parallel to the first contact surface and facing it, wherein the first recess is dimensioned to match the dimensions of the screw channel of Basic profile is tuned and can be plugged onto the screw. By providing the second Contact surface, which can be applied to the second outer wall of the screw, there is a secure positioning of the guide device relative to the base profile, so that a faulty application of the guide device is excluded relative to the base profile.

Preferably has the guide device a second recess, the axisymmetric to the longitudinal axis of the implementation relative is arranged to the first recess. The guide head thus has two Openings on which optionally on the Tightening channel of the basic profile can be inserted. Depending on whether the first or second recess on the screw of the basic profile plugged is, is the implementation for driving a nail on one side or the other Screw channel. In this way, with a single guide device and without the direction of actuation change the setting tool to have to a quick preselection of the side of the basic profile relative be taken to the screw, driven on a nail shall be.

The guide means can preferably be made of aluminum with an anodized surface or but made of plastic with good sliding properties. alternative can the leadership device but also be made of steel or stainless steel.

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. In the illustrated 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 facade construction is shown, it should be clear that the profile frame construction can generally represent a vertical facade, polygon facade, glass roofs, but also other frame structures, in which the basic elements described below are present in the same way.

The substructure 10 is made of wood and is designed as a rectangular profile. In the material of the substructure are fasteners 20 of which in the illustration in 1 only the head is visible. The fasteners 20 serve a basic profile 12 on the substructure 10 to fix.

In the 1 illustrated geometry of the basic profile 12 is only an example, in particular with respect to the dimensions of the illustrated screw channel 25 and the attachment approaches 27 for a one-piece or multi-part weather strip 16 , In the present case is a one-piece inner sealing strip 16 provided, extending over the screw 25 extends. However, it should be clear that in addition to the embodiments 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 in the same way are possible, as well as multi-part inner seals. 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 to a pressure bar 26 with the interposition of external seals 28 against the basic profile 12 to tension around the filling elements 18 to fix.

The essential aspect of the invention is to attach the base profile on the substructure on wood. 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 or plastic, such as glass fiber reinforced polyamide. The basic profile is made by means of the fastening elements 20 punctiform on the substructure 10 made of wood. These nails are used as fasteners. The nails are best preferably made of steel, galvanized steel or stainless steel. The attachment is usually done with the help of a nail-setting tool with which can be driven through the base profile into the substructure in relatively quick succession, the nails. The advantage of choosing the fasteners 20 as nails 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.

As is apparent from the schematic representation in 1 it can be seen in the longitudinal axis of the nails 20 in the substructure 10 is shown, the nails are driven at an angle α to the contact surface between the substructure and base profile, but also at an angle to each other. Define a midplane 19 so that these are the longitudinal center axes of the individual facade screws 24 contains, so are the nails 20 so driven into the basic profile that its longitudinal axis is at an angle to the median plane 19 is and approach the nails with increasing distance from the contact surface between the substructure and the base profile of the median plane.

To illustrate the diagonally inserted nails 20 are in the illustration after 1 shown on both sides of the screw nails. This gives the impression that the nails are arranged on both sides of the screw channel in the same cross-sectional area of the post or bar. However, since it is just to reduce the risk that the wood splits by the helical nailing, it is of course preferred to drive the nails on one side of the screw each offset with respect to the longitudinal direction of the profile to the nails on the other side of the screw. For this purpose, there may be holes in the base profile, which serve for the passage of individual nails, while the widened nail head can not pass through the corresponding holes. Alternatively, it is also possible to use a setting tool with a correspondingly high impact force, for example a pneumatically operated setting tool with high performance, and to pierce the base profile when inserting the nails. This alternative has the advantage that, unlike the specification of individual holes in the base profile, the mounting density of the nails can be adapted to the static requirements. The advantage of the holes in turn is that according to a required stress on the connection between the substructure and base profile of the hole spacing and thus the number of nails per meter can be fixed and the force required for driving the nails is lower. The disadvantage of the embodiment with holes but again is that an exact positioning of a setting tool for driving nails or staples in the longitudinal direction of the base profile is required.

In 3 Different types of nails are shown. The nails can be made smooth, as with the nail 21a is shown, or grooved according to example 21b be designed. 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, so that the nail screws can be unscrewed during disassembly of the profile frame construction again from the substructure.

The Nail diameters are between 1.5mm and 5mm and are preferred between 2.5mm and 3.5mm while the shaft length the nails over one wide range between 25mm and 150mm can be selected. Prefers are shaft lengths between 45mm and 90mm.

The Selection of nails takes place in coordination with the material of the substructure, preferably from spruce, larch or multiplex exists.

When driving in the nails compressed air driven Stauchkopfnagelvorrichtungen are preferably used as setting tools. It depends on the exact positioning of the nail devices, because the in 1 schematically illustrated angle α between the longitudinal axis of the nails and the median plane 19 between 3 ° and 10 ° and preferably about 5 °. In order to facilitate the user the exact positioning of the nails when driving, the nailing device may be equipped with a guide device, a in 3 having shown guide head. The guide head itself has a length L of about 60mm and is preferably made of aluminum with an anodized surface or plastic with good sliding properties. The guide head 30 is specifically aligned with a facade system and in particular the shape of the base profile, so that it has a fastening device, not shown, to attach the guide head to a nail device.

The function of the guide head 30 consists of one or more bushings 32 show, by a nail from the nail device accurately driven through the basic profile in the substructure. For exact positioning of the guide head 30 optionally serve a first recess 34 or second recess 36 , the each a first contact surface 38 have, with the help of which the guide head 30 is flush with an outer wall of the screw can be applied. The implementation 32 is in the above-mentioned angle of 3 ° to 10 ° and preferably about 5 ° relative to the first contact surface 38 inclined, so that after the flush application of the first contact surface to the outer wall of the screw a nail, depending on which of the contact surfaces has been used, can be driven on one or the other side of the screw.

The first recess 34 and second recess 36 are axisymmetric to the median plane of the guide head 30 arranged, wherein the longitudinal axis of the driving opening is located on this median plane. This means that the first contact surfaces 38 are at an angle to each other, which is twice as large as the desired angle α, with which the nail is to be driven.

The use of the guide device turns off 4 can be seen in the relative position of the guide head 30 is shown in two different positions. In solid lines, the guide head with 30a referred to while the alternative position of the guide head 30b is shown in broken lines.

How out 4 it can be seen are both the first recess 34 as well as second recess 36 dimensioned so that they play well or with little clearance for receiving the screw 25 of the basic profile 12 serve. By attaching the guide head 30 on the screw is the relative position of the bushing 32 fixed to the basic profile. Will now pass a nail through 32 driven, this receives the desired angular direction relative to the center plane defined by the center of the screw (see median plane 19 to 1 ). Due to the symmetrical design of the guide head 30 But nails can not only on one side of the screw, but in the same way and symmetrically drive this on the other side of the screw. For this purpose, the guide head 30a only pulled up and put back with the other recess on the screw, so that the guide head now in the reference numeral 30b is shown position. In this way, an alternating driving of nails can be performed under a precisely predetermined angle quickly and reliably.

The Insertion of the fastening nails at a predetermined angle reduces the risk that a nail the Wood splits as well as the risk of getting a nail at low edge distances Outside looming. Especially hard woods can not be ruled out that the nail is deflected when driving in and within the Substructure bends. By the angle driving the nails is therefore even with an unwanted Bending a nail the danger encountered that the nail Outside could sign on the substructure.
