Insulating building board connection arrangement

The invention relates to an insulating joint arrangement for building boards and in particular to a façade structure according to the preamble of claim 5 carrying glass panels, and to a plastic spacer according to the preamble of claim 12 for such a joint arrangement.

An insulating connection arrangement of this type is known, for example, from DE-OS 31 07 725. This connection arrangement uses plastic spacers, the front split ends of which are tightened in the grooves of the body parts by inserting a pin, which may be formed, for example, as a nail or screw. In addition, this known connection arrangement 15 has securing plates for fixing the building boards to the frame parts, which can be used as an aid for installation before the final fixing of the building boards by means of the frame parts and the facade frame parts. To this end, the fastening plates are fastened to the shortened plastic spacers 20, which, however, do not have fastening elements for the outer façade frame parts. In other words, this means that two different types of plastic spacers are formed in connection with this structure, in which case the latter can be used only for the temporary fastening of the building boards by means of securing plates.

Although this type of connection arrangement is in practice completely satisfactory and effectively avoids the disadvantages of the connection arrangement known from CH-PS 501 135, for example, certain improvements in terms of cost reduction in installation and avoidance of various building elements are desirable.

This also applies to the second structure known from DE-OS 2 021 536, which is described as a cladding wall, in which the connecting pieces are made of heat-insulating material in the form of pins which adhere formally behind the longitudinal grooves of the columns at their inner end. they are connected at their outer end to the outer frame profiles 5 after insertion of the wall fillings, for example by a screw.

In another thermally insulating aluminum façade truss construction method used in practice, polyamide strips are arranged between the column profile and the compression profile 10 for thermal insulation, the ends of which in each case adhere to the column or compression profile in a lateral protrusion. This structure is also relatively expensive in terms of installation technology and thus also in need of improvement.

It is therefore an object of the present invention to provide an insulating connection arrangement as set out in the preamble of claim 1, which makes it possible to calculate the cost of installation and parts.

This object is solved by the features of claim 1.

This ensures that the plastic spacer and the pin form a single unit which is already in the correct position before the final installation, so that in order to fasten the end of the spacer it is only necessary to move the pre-assembled pin to the locking position when the planned breaking point breaks. This can happen, for example, by hitting with a hammer.

In addition, the very advantageous effect is obtained that, if necessary, the securing plate of the connecting arrangement according to the invention can be mounted immediately on the spacer piece, to which the outer facade frame parts or cover profiles are also attached. This means that only one type of spacer is needed, which can be used to attach both the backing plate and the cover profile, if necessary. In addition, in connection with the advantageous reduction in the number of individual parts required for the connection system according to the invention, the installation is also facilitated.

The dependent claims contain preferred embodiments of the invention.

If a control device is formed on the spacer, which surrounds the spacer, very advantageous installation conditions are obtained, since no changes are required in the locking parts to fasten the external façade frame parts, as they are not disturbed by the mounting plate installed in their arrangement and operation.

A very preferred embodiment 10 of the control device is seen in claim 3, according to which interlocking teeth are formed which allow a subtle displacement of the securing plate and thus trouble-free adaptations to different building board thicknesses.

The formation of a hole as part of the control device makes it possible to grip the spacer on all sides, so that a secure holding of the release plate is guaranteed here.

The mounting of the teeth at right angles to the strips projecting from the surface of the securing plate provides additional stability for the control of the securing plate and also forms a simple fitting.

Preferred further developments according to claims 6 to 11 further simplify the installation due to the fact that the wedge-laying along the obliquely extending support surfaces of the teeth of the locking part makes it possible in a simple manner to adjust the distance of the outer public frame parts or cover profiles. Which, on the basis of the complementary angles acting together with the teeth of the locking part and the first support surface, again form a support surface parallel to the building board, this parallel support surface being more or less relative to the plane of the building board, depending on the adjustment of the key. moved in one of the two directions, which gives the possibility of adjusting the distance of the outer cover profile, in order to avoid the wedge falling out in the event of possible vibrations, its longitudinal slot n long 5 inner sides are equipped with cam-like locks.

Finally, claim 12 defines a plastic spacer as a self-handling part for a joint arrangement, it being emphasized that the spacer according to the invention does not necessarily have to be connected to a securing plate, but can also be used without a securing plate alone to install cover profiles due to temporary fixing of building plates. not necessarily to occur with each spacer formed. On the contrary, it is only possible to equip a certain number of spacers with a securing plate, as this is perfectly sufficient to secure the building boards in position.

Other details, features and advantages of the invention will become apparent from the following description of application examples 20 with reference to the drawings.

In the drawings: Figure 1 is a perspective partial view of an insulating joint arrangement according to the present invention; Fig. 2 is a plan view of a plastic spacer according to the first embodiment; Fig. 3 is a side view of the spacer of Fig. 2; Fig. 4 is a plan view of a securing plate connectable to the spacer 30 of Figs. 2 and 3; Fig. 5 illustrates a narrow side of the securing plate of Fig. 4; Fig. 6 is a sectional view of a part of the connecting arrangement in the installed state of the spacer; Fig. 7 is a view corresponding to Fig. 2 of a second embodiment of a spacer; 93669 Fig. 8 is a description of the spacer of Fig. 7 corresponding to Fig. 3; Fig. 9 is a plan view of a wedge to be connected to the spacer of Figs. 7 and 8; 5 and Figure 10 are side views of the wedge of Figure 9.

Figure 1 shows an insulating joint arrangement 1 for building boards 2, which can be formed in particular as a façade structure bearing glass sheets.

The connecting arrangement 1 has a plurality of intersecting body parts, of which Figure 1 shows a box-shaped vertical body part 3 and likewise a box-shaped horizontal body part 4. The body part 3 has a longitudinal groove 5 15 extending over its entire length and part 4 a longitudinal groove 6.

The connecting arrangement further comprises plastic spacer pieces, of which the spacer piece 7 is representatively illustrated in the figure. These spacer pieces 7 act to fasten the outer public body parts or cover profiles, of which two cover profiles 8, 8 'are shown in Fig. 1. The cover profile 8 has a longitudinal locking groove 9 and the cover profile 8 'a longitudinal locking groove 9', to which the locking parts of the spacer pieces 7 to be described later engage in order to fasten the cover profile 8, 8 '.

.25 In addition, the connecting arrangement 1 according to the invention has a plurality of building plate support parts, of which the support part 10 is illustrated in Fig. 1. This is fixed to the longitudinal groove 6 of the horizontal frame part 4 and has a support surface on which the respective building plate 2 can be supported.

In addition, Fig. 1 shows a securing plate 2 * which acts to fasten the building plates 2 from its position. However, the securing plate 2 'shown in Fig. 1 represents a securing plate used so far, which in principle can also be connected to the spacers / 6 93669 according to the invention, which nevertheless requires the formation of a separate fastening part, which according to the present invention can be avoided. spacers. The formation according to the invention is described in more detail below. For other already known details of the connection arrangement 1, reference is made to DE-OS 31 07 725, the disclosure of which is hereby incorporated by reference to be used to illustrate the present invention.

Also described below with reference to Figs. 10 and 3 is a first embodiment of the spacer 7 illustrated in Fig. 1 in a state attached to the body 4, however, the outer facade body 8 is not yet attached to the spacer 7 so that its general fit to the inner body 4 can be present.

For the sake of completeness, it should be mentioned at this point that, of course, also according to the description selected in Fig. 1, spacers 7 are formed for fastening the vertical cover profiles 8 ', which engage in the longitudinal groove 5 for fastening to the vertical body part 3.

Figure 2 shows a top view of a first embodiment of the spacer body 7. It can be seen from this top view that the outer contour of the spacer body 7 is substantially rectangular. The spacer piece 7 .25 is made of plastic in order to form a cold bridge cut between the inner frame parts and the outer load-bearing façade frame parts.

The spacer 7 has in detail an end 11 with side-ul machines, which to form the end-strips 11a, 11b shown in Fig. 3 is provided with a slot 12 which, viewed longitudinally of the spacer 7, ends in the end wall 13 but extends over the entire width of the spacer 7. . The fitting of this gap 12 results in a flexible recoil of the main strips 11a and 11b 35, so that when pressed 7 93669 into the longitudinal grooves 5 or 6 of the body parts 3 or 4 they resiliently resiliently opposite, allowing locking in the longitudinal grooves 5 or 6.

As is apparent from the description of Figures 2 and 3, the spacer 7 has at its other end a total of four locking parts 14 to 17 projecting outwards from tongues formed by placing two intersecting slots 18 and 19. The locking parts 14 to 17 engage in a locking groove 9 or 9 in the final installation space. 'in the outer cover profile 8 or 10 8'.

As further shown in Figs. 2 and 3, the spacer pieces 7 are formed in one piece with a pin 20 extending in the slot 18 along the longitudinal central axis. The pin 20 is pivoted from the indicative breaking point 15 not shown in Figures 2 and 3 into the end wall 13, and its end 21 protrudes slightly over the end wall 13 in this state, as can be seen in Figure 3. Furthermore, it will be apparent from Figures 2 and 3 that the pin 21 opposite the head 21 the head protrudes a considerable amount over the locking parts 14 to 17 20, so that in order to fasten the main strips 11a and 11b to the longitudinal grooves 5 or 6 of the body parts 3 or 4 the pin 20 can be inserted from this side into the gap 12 between the main strips 11a and 11b. which acts to secure the head 11 to the longitudinal grooves 5 or 6 of the body parts 3 or 4 corresponding to .25.

The outlines of the main strips 11a and 11b are arranged in longitudinal grooves 5 and 6, which are preferably formed approximately in the shape of an arrowhead.

In addition, Figs. 2 and 3 show that the end 11 has in addition two transverse support strips 22 and 23 which join internally to the main strips 11a and 11b and which, in the installed state of the main spacer 7 according to Fig.

By forming a pin 20 connected in one piece from the indicative breaking point 35 to the strip piece, the installation is considerably simplified, since the pin 20 is already in the correct position before installation. In addition, this arrangement can be manufactured at once, which reduces acquisition costs.

Figures 2 and 3 further show that the spacer piece 7 is provided with teeth 28 or 29 in each case at a substantially right angle to the side surfaces 26 and 27 associated with the cover surfaces 24 and 25. These teeth 28 and 29 form a part which in Figures 10 4 and 5 with the control device 30 described in more detail below.

The securing plate 30 has a substantially rectangular shape and has a rectangular hole 31 arranged along the longitudinal central axis, in the illustrated embodiment.

The hole 31 is provided on its narrow sides with two strips 32 and 33 rising perpendicular to the surface of the securing plate 30, which are provided with ribs 34 and 35 to improve strength. The strip 32 is provided with teeth 36 and the strip 33 with teeth 37 facing each other 20. In order to attach the securing plate 30 to the spacer piece 7, the securing plate 30 is pushed through the hole 31 in the spacer piece 7, whereby the strips 32 and 33 point towards the locking parts 14 and 15. During this pushing, the inner teeth 36 and 37 engage the outer teeth 28 and 29 of the spacer 7, as a result of which it is possible to adjust the securing plate 30 along the longitudinal axis of the spacer 7 and lock the securing plate 30 to the spacer 7 in the adjusted state.

In connection with the securing plate 30 30 arranged on the spacer piece 7, the building plate 3 can be fastened to its respective thickness in position, which considerably simplifies subsequent adjustment work and the fitting of the outer cover profiles 8-8 '.

As already mentioned, in this case it is not necessary to provide each spacer piece 7 necessary for forming the connecting arrangement 1 according to the invention with a securing plate 30. Rather, only as many securing plates 30 are formed as are necessary for fixing the building plates earlier.

In order to clarify the final installation space of the connecting arrangement 1 according to the invention, Fig. 6 shows this part, whereby it becomes clear how the main strips 11a and 11b are fastened with the inserted pin 20 to the longitudinal grooves 5 or 6 of the body parts 3 or 4. , that a second shape of the external cover profile is formed, which is provided with an external visual protection 38, so that the strip parts 7 are not visible from the outside and so that a smooth and beautifully shaped visible surface can be formed.

Figures 7 and 8 illustrate another embodiment of the spacer body 7 '. As will be apparent from a comparison of Figures 7 and 8 with Figures 2 and 3, this spacer 7 'corresponds to an embodiment of the spacer 7 in terms of forming the head 11 and the central portion with external teeth 28 and 29, the spacer 7' being provided with a one-piece connected pin 20. has been omitted from Figures 7 and 8 for simplification of description.

It should be emphasized, in contrast to the spacer 7 described in Figures 2 and 3, that the spacer 7 'does not have a transverse slot 19, but is provided only with a longitudinal slot 18'.

However, four locking parts 14 'to 17' with side projections are likewise formed, which, however, are arranged only on the opposite sides of the two tongues, in which, as said, only one longitudinal slot 18 'is formed.

A special feature of the embodiment according to Figures 7 and 8 is that the locking parts 14 'to 17' have support surfaces 39, 39 'to 41 extending obliquely at an acute angle α relative to the reference line B. The reference line B is arranged at a right angle to the longitudinal axis L of the spacer body 7 ', as shown in Fig. 7.

The inclination of the support surfaces 39, 39 'to 41 allows adjustment of the wedge 42 illustrated in Figures 9 and 10. The wedge 42 is formed in a substantially U-shape and has two substantially parallel arms 43 and 44 connected to each other by a connecting leg 45. Thus, a longitudinal slot 46 is formed, with Figure 9 showing 10 that the leg 44 may deviate somewhat in the direction of the leg 43 from a position parallel to this relationship to ensure a firm position as the wedge 42 protrudes over the spacer 7 '.

The arms 43 and 44 have chamfers 47 and 48 at the opposite end to their arm 45, which further facilitate insertion. In order to avoid the wedge 42 falling off in the event of possible vibrations, the two inner surfaces forming the longitudinal groove 46 of the substantially parallel branches 43, 44 are provided with securing means 53, 54, which are preferably formed as a cam.

It can be seen from Fig. 10 that on opposite sides of the branches there is in each case a first support surface 49 and a second support surface 50 divided into slots 46. The first support surface 49 then joins an end surface 51 arranged on the branch 45 at an angle 6 dimensioned so that the wedge 42 is inserted over the spacer 7 '. in connection with this, the second support surface 50 is oriented parallel to the opposite surface of the respective building board 2. Here, the support surface 50 joins the end surface 51 at right angles.

All in all, this structure makes it possible to push the wedge 42 over the part 52 bordering the support surfaces 38-41 of the spacer 7 ', whereby the area 52 is introduced into the longitudinal slot 46 of the wedge 42. Thus the support surfaces 38-41 will press into the first support surface 49. depending on how far the wedge 42 is pushed onto the spacer 7 ', a displacement of the parallel support surface 50 in the direction towards or away from the end 11 of the spacer 7' is obtained. Since the locking groove 9 of the cover profile 8 or 8 'is pressed against the support surface 50, this structure makes it possible to adapt to different building board thicknesses, which can be implemented in a simple manner and can be converted steplessly.

It will be clear from the above description of the application examples 10 of the invention that the invention provides considerable savings due to the reduction in the number of individual parts required for the connection arrangement 1 and the clearly simplified installation of the device.
