DE3308233A1 - Framework having insertion members to be inserted between the frame elements thereof - Google Patents

Abstract

In a framework comprising frame elements (2) joined together at nodes, insertion members (32, 33) to be inserted between these frame elements are locked by means of catch devices (28). The catch devices (28) have self-acting spring catches, preferably leaf-springs, and are each held longitudinally displaceably on the frame element (2) and/or insertion member (32, 33). The insertion members (32, 33) are pushed into the framework transversely to the frame plane. The normally required sealing can be produced with a single pushing-in movement. After erecting the framework, a wall can normally be completed within a few minutes. The erection times for infilling the framework are negligible. It is also possible to employ materials with a quite different thermal expansion behaviour in association with flexible abutments, without the holding safety or the sealing suffering. <IMAGE>

Description

Framework with between its framework

elements to be inserted insert parts The invention relates to a Framework from frame elements joined together in nodes with between these insert parts to be inserted.

Frameworks of this kind are mainly flat or spatial in metal construction Structures known in various designs. Main areas of application are partition walls, but also outside walls, scaffolding, shelves and the like .. There is a flat framework usually .. from vertical frames and horizontal transoms, sometimes, provided No lateral building support is possible, struts, such as diagonal struts, retracted will. Posts and transoms usually form a grid-like structure and enclose it individual frame fields, which are then filled in with special insert parts will. Such insert parts can in principle be of any design, for example also protrude outward from the plane of the frame, but usually they have the shape of panels with their edge, possibly under sealing, with special fasteners be attached to the frame bars and thus in the frame field all around. As a fastening medium mostly screws, every now and then Terminal strips are also used, which in turn are often clamped by screws. Both are complex and require time-consuming and costly assembly processes.

The invention is based on the framework described above and pursues the task of making this framework as simple and inexpensive as possible, that the assembly is significantly simplified.

To solve this problem, according to the invention, between frameworks and insert parts Latching devices for locking the insert parts in the framework intended.

Ratchet devices of this type are known in various designs. For example, they have the advantage over screws and other bracing devices an uncomplicated and instant switching between initial position and Bolt position. You only need to "latch" the insert parts and only have make sure that the latching devices are also effective and the insert part lock in the framework or determine.

That it has proven to be particularly advantageous / the ratchet devices by the particular against an elastically resilient abutment, such as a seal have to be exerted insertion pressure of the insert parts automatically switching spring pawls. The insert parts are then only inserted into the framework transversely to the frame plane pressed in, whereby the resilient abutment applies the counter pressure to a reliable to ensure frictional engagement by means of the ratchet devices in the frame. With a single push-in movement, the most necessary Establish a seal. After the framework has been set up, a Wall mostly one A matter of a few minutes. Anyway will be the assembly times for flattening the framework are negligibly small.

The spring pawls are preferably bent in particular several times Bar springs, preferably designed as leaf springs, are therefore practical in terms of cost no meaning.

Whether you use such leaf springs or other latching devices, they can easily be attached to the framework and / or insert along their frame element adjustable, especially keep it slidable. In this way, a setting can be made create in the whole frame level. In connection with flexible abutments or Seals can then also be made of materials with very different thermal expansion behavior can be used without the security of the hold or the seal being impaired.

So it has proven to be useful, the latching devices in each case in longitudinal guides of their frame element, in particular longitudinal slots of a hollow profile frame rod to keep. Suitable bar profiles are freely available, especially for light metal bars, but also with frame bars made of closed tubes, such as steel tubes, corresponding recesses can be punched in without further ado, since there are only to expansion lengths in the order of magnitude of a maximum of 1 mm to 2 mm, the Longitudinal adjustability is therefore extremely limited.

The spring pawls that are preferably used can be placed on opposite sides Pages in particular one-piece molded retaining elements for engagement on the frame element and have on the insert. So the leaf spring latch holding tongues stamped on a first side for the holder on the frame rod have, and on the opposite second side, their ends can be used as ratchet blades be bent back like a barb. The initially exhibited wedge-shaped The latch blades are loaded against the wedge direction and thereby swiveled back, while they snap back when passing their end and then their latch function carry out.

The opposite directions behind the flange edges of the frame elements gripping retaining tongues can be along their adjustment guide on the frame part in this way Staggered to each other so that they fit snugly into the holding position as a swivel bolt are pivotable. They are simply twisted by approx. 90 "into the holding recess inserted and then rotated.

It has proven to be particularly advantageous1 along a Arched path pivotable ends of the ratchet blades on the insert part of the arched path adapted, in particular in the locking position approximately tangentially adjoining this Assign support area. The pawls can then move after reaching the maximum Operating pressure without further relocation of the insert part in the framework completely Move to the end position without losing contact with the abutment surface. Then the relative arrangement of the frame element and the insert part is also independent of the respective pivot position of the pawl.

This arrangement is of particular importance in the event that the slidable one opposite the support surface and absorbing the application pressure Abutment surface is arranged at least approximately parallel to the support surface. Different L Length dimensions or expansion of the framework and insert part in the frame plane to have thus only a parallel shift of the insert part on the framework.

In order to save profile thickness here, it may be appropriate to use the abutment surface on one of the adjoining components in individual sawtooth-shaped adjoining Subdivide surface elements.

It can also be expedient to have at least the sliding abutment surface to be attached indirectly to a rubber-elastic deformable abutment. So can about the flexible abutment has a strip direction that surrounds a frame opening or have a ring seal, which is inserted into the profile grooves of the frame bars and also has a static support function in addition to its sealing function. Suitable rubber-like plastics that also work in temperature ranges below freezing point remain sufficiently elastically deformable are well known.

The insert parts preferably have a surrounding insert frame, which encloses and holds a middle insert filling, as well as support and abutment surfaces having. This insert frame protects the filling, which is adapted to it, and facilitates handling. This is independent of the fact that fillings such as window panes can in turn be encompassed by a separate frame made of metal or plastic.

For at least some of the frame fields to be filled in, both sides Provide latching devices and insert inserts from opposite sides. The insert parts to be attached in the same frame field can also be quite different be designed, depending on which space they delimit. This double arrangement is likely be the rule wherever one- on the one hand the outer surface of the framework must meet certain requirements on both sides and also thermal insulation is to be achieved.

Thus, the insert filling can be at least approximately dimensionally stable and, if necessary, have an outer layer that can be decorated and a heat-insulating inner layer, no special requirements are placed on their appearance, strength and the like. The two filling layers can also be easily separated from opposite ones Hold sides against stops of the insert frame against each other, for example in such a way that the inner layer on the back of the plate-shaped outer layer in the insert frame is foamed.

According to the invention, the outer layer can also be made with a resistant one Covering layer provided semi-hard board be designed like a plasterboard. Such plasterboard or comparable products are extremely inexpensive offered by different manufacturers, but can also be done without any special costs with a very attractive coating, for example applied using a paint spray process are provided, which can also be designed decorative.

When designing the framework, it is currently preferred to use latch bars with their ends detachable by butt connectors on vertical posts in their plane to connect. In this way, the entire frame or even a spatial scaffolding can be set up quickly and easily assemble from individual bar elements and form or force fit associate.

The butt connectors can each have abutments on the mullion and transom bar, which can be clamped against each other by clamping means such as screws. It should at least the abutment part of the post releasably thereon, in particular along the post adjustable, be provided.

In the frame filling of a latticework made of posts and transom bars In particular, movable sub-frames such as windows or doors can also be inserted will. Leave it at the edges of the framework to improve the finish the end posts, also from possibly movable subframes, separate connection profile strips with brackets for the outer layer of the insert panels, corresponding cover strips assign.

The drawing shows the invention for example.

1 shows a view of a framework according to the invention with insert parts for a partition to be drawn in in a building, FIG. 2 a three-dimensional representation of the node II in Fig. 1, with individual wall parts 3 are a side view of a leaf spring pawl, FIG. 4 a This pawl is viewed from below in FIG. 3, FIG. 5 shows a partial section the line V-V in Fig. 1, Fig. 5a in an enlarged excerpt view the assignment a leaf spring latch to an insert part that fits into the frame field inserts, Fig. 5b the same representation with a shortened in the frame plane Insert part, FIG. 5c the position in the case of an insert part extended in the plane of the frame, 6 shows a section through a wall termination used here as a floor termination according to the line VI-VI in Fig. 1, where as in the following Fig.

Frame bars are shown as square tubes, Fig. 7 shows a section through the hinge connection of a door and FIG. 8 shows the corresponding one Section through the end of this door.

The planar framework 1 shown in Fig. 1 is assembled from vertical posts 2 and horizontal bars 3 and fits into a building Opening between the floor 4, the ceiling 5 and the side walls 6, 7.

While the posts 2 all over the entire height of the building opening are passed through, the locking bars 3 each extend between adjacent ones Posts 2 and are attached to them by the butt connectors shown in FIG. 2 connected that mullions and transom bars lie in the same frame level.

As a result, frame fields 8 are in each case in a lower line, frame fields 9 divided into a middle and frame fields ii in an upper row. In the right row is formed by omitting a latch rod 3, a door opening and in this a door 12 is attached. All frame fields 8, 9 are wall insert parts filled in, -the frame fields 11 by window insert.

As can be seen from Fig. 2, posts 2 and frame bars 3 have the same Cross-section. They are as light metal profile tubes with an essentially rectangular cross-section formed, on a rectangular inner tube with two opposite Walls 13, 14 are formed in a mirror-inverted manner with holding flanges 15, 16 spaced apart and form a longitudinal slot 17 between them.

On the other two sides, starting from the flanges 15, 16 each angle strips 18, 19, 21, 22 formed, the two T-shaped grooves 23 for Recording of Form sealing strips.

Close to each end of a frame rod 3 is a rectangular one Coupling recess 24 molded into the two walls 13, 14. In this coupling recess a retaining plate 25 engages, which is braced against an anchor plate 27 by screws 26 are behind two flanges 15, 16 of the post 2 on this longitudinally displaceable is held. The butt connector formed in this way makes it possible to use the uniform Frame bars can be adjusted along the posts at will, but still reliable to brace. All frame bars can be cut to length and finished with the provide the desired surface protection, e.g. B. anodized.

For fastening and holding the various types of insert Leaf spring pawls 28 made of spring steel sheet serve on the frame bars, as shown primarily in FIGS. Output parts of the leaf spring pawls 28 are rectangular spring steel leaves, from the center of which two retaining tongues 29 are punched out and bent back around 1800. Their distance a from the leaf spring body 43 corresponds the thickness of the flanges 15, 16. Both retaining tongues are transverse to the longitudinal direction of the Blade body offset so far that it is in the longitudinal position in the slot 17 downwards pressed and then swiveled under the flanges 15, 16 by turning 90 ", until the leaf spring pawl 28 assumes the position shown in FIG.

The ends bent back over approx. 1500 upwards form a wedge shape protruding resilient ratchet blades 31, each of the latching process between Frame elements and two insert parts to be inserted into the frame fields from both sides to accomplish.

Thus, according to FIG. 5, first insert parts 32 are at the bottom of the frame rod 2 Wall function and above second insert parts 33 connected with window function. Both insert parts have in common a circumferential one formed from individual rod profiles metallic insert frame 34 or 35.

Both insert frames also have an anchor part 36 with one in common abutment flange 37 lying parallel to the frame plane and an inwardly inclined one protruding latch flange 38 with a nose rib 39. The abutment flange is supported 37 via a sealing strip 41 made of rubber-like material, which is guided all around from, which sits in one of the T-shaped grooves 23 of the bar profile.

The nose rib 39 has on the inside a support surface 42 which is around the same angle d to the frame plane as the ratchet blade 31 to the base body 43 of Leaf spring pawl 28 is inclined. With this nose rib 39 are when pressed of an insert part, the pawl blades 31 are pivoted partly against the leaf spring body 43, partly bent, the sealing strip 41 becoming increasingly compressed until finally the nose rib 39 over the free end of the ratchet blade 31 is reached and this is bent back and pivoted back about its bend 44 will. This angling forms approximately the reference point of a swiveling curve, to which the support surface 42 hugs as a tangent. In any case, the rib of the nose locks 39 behind the free end of the ratchet blade, which thus a locking element and in connection with the opposing sealing strip 41 a somewhat resiliently flexible resilient bracket forms, the frictional connection is determined by the latching force.

The inner surface 37 of the Wi, the bearing flange, which forms an abutment surface 30 is parallel in the illustrated preferred embodiment as an inclined surface to support surface 42 educated. This way they become different Length dimensions and compensatory movements in the frame plane, as they are due to different Thermal expansion can be caused by slight shifts in this Level balanced, but the holding force remains the same.

The effect of the leaf spring pawls can best be seen from the enlarged Recognize representation in FIGS. 5a to 5c. The insert frames 34 close in the process and the wall 231 of the sealing strip 41 receiving groove 23 in the same Level down. With broken lines 311 is the position and shape of the pivoted and slightly bent pawl blade 31 denotes that at the moment of passing the nasal rib 39 along the support surface 42 in the drawn as a full line Bolt position swivels. The path of the end of the latch blade is right exactly coincides with a straight line that can also be seen as a tangent to the swivel arc can. In any case, practically no displacement occurs when the pawl blade 31 is pivoted out of the frame part used transversely to the frame plane. Here comes the end of the Leaf spring pawl at a certain distance from the inner end of the support surface 42 to rest and there acts a locking function against pull-out movements. It will the insert 32 is also centered in the frame field, with a displacement from the central position the friction on the abutment surface 30 also counteracts it. However, this friction is usually not so great an expansion or contraction of the insert element to prevent in its plane under the influence of heat.

Insert elements with length tolerances are also often delivered. Thus, the surface dimension according to FIG. 5b is smaller by about 2b, so that the connecting parts shift at both ends by the length b. Taking into account the Angle of inclination d of the abutment surface 30 results in a displacement of bl to the outside. This shift parallel to the abutment surface 30 and thus to the support surface 42 arises on the whole Insert frame, so that the end of the ratchet blade 31 to the outer end the nose rib 39 moves towards without changing the spring tension.

Conversely, with a larger length dimension according to FIG. 5c the outer end of the ratchet blade 31 relocated umb to the connecting part of the nose rib 39, and the outer surface 48 of the outer plate 47 and thus of the insert part 32 is around bl shifted outwards. This does not change the effectiveness of the hold function, and the outward shift does not have to appear when between adjoining Insert parts separate seals or just sealing panels are inserted.

Since a single inclined abutment surface 30 is relatively transverse to the frame plane takes up a lot of depth, it can be broken down into individual sloping surface strips, which are connected in series in a sawtooth manner.

The insert frame 34 forms each with an outwardly / inwardly open Edge groove 46 is a cuboid space that is completely filled by an outer plate 47 will. This can be a plasterboard or the like. In particular has undergone a surface treatment on the outer surface 48 that corresponds to the respective Purpose is adapted and decorative as well as strength and hardness can have an enhancing effect. On the inside of the outer plate 47 is a thermal insulation layer 49 foamed, which engages behind a bevel 51 of the rib 39 and thus also the Outer plate 47 sets in the insert frame.

In the case of the insert frame 35 of an insert part, only one is different inwardly open U-shaped retaining groove 52 for the turn U-shaped metallic Edging 53 of the window pane 54. There is a screen between sealing strip 40 inserted into the nose ribs 39. However, it is not essential necessary to provide separate insert frames 5. In principle, the edging can also be used 53 for the window pane 54 directly in the edge groove 46 through various available Means to be set. This does not exclude the possibility of using all frames outside provides an inwardly projecting flange part which, for example, also has the edge the outer plate 47 is detected. Of course, adhesive connections to the Use.

The one remaining between the adjacent insert elements 32, 33 Gap 55 can be closed in a known manner by a further sealing strip that creates a thermal insulation against the frame rod and thus inhibits the flow of temperature between the rooms separated by the wall. The interior between opposite insert parts is in any case by their impressions into the latching position instantly through the sealing strips 41 to the outside closed. A further improvement of the thermal insulation can be achieved by that in or on the insert filling, in particular on the inside of two opposite ones Insert fillings heat-reflecting layers are attached to the heat balance counteract by thermal radiation.

According to FIG. 6, there are sealing strips in place of the sealing strips 141 provided with a rectangular cross-section.

In addition, the frame rod 56 is designed as a smooth rectangular tube, be a steel tube and only insert openings 57 for inserting the leaf spring pawls 28 and 58 for connecting end profile rods 59. Corresponding Modified are also the insert frames 134, as well as, if necessary, the end profile rod 59 can be formed by folded steel sheets. These end profile bars can directly adjoin the insert frame 34 and form U-shaped on the outside Grooves 60 are inserted into the outer plates 147 corresponding to strips of material 61 permit. Furthermore, a layer of insulating material can be used for sealing against the floor 4 or a wall 62 can be inserted.

As can be seen from FIG. 7, the surface dimensions Apart from that - the same insert parts for the frame fields 8 and 9 and the door 12 Use 132, which in the manner shown in FIG. 6 on a frame rod 56 connected, with both frame bars partly with one opposite to each other arranged T-shaped end rod 63 are provided. The door hinge can then be in be laid outwards from the middle frame level in a known manner.

The outer part of the door 12 is similar to the embodiment of FIG. 6 with two T-shaped rods 59 provided, which carry a sealing lip 64 between them, the cooperates with a double wedge strip 65 attached to the wall 7.
