Panels and posts, in particular for building purposes

The invention relates to industrially manufactured building elements, namely panels and posts, in particular for Construction τοη single houses and apartments. These panels are self-supporting and the posts are capable of to absorb additional loads, such as those resulting from the roofing, for example.

101883/1346

The plates and posts according to the invention are characterized in that they have a core made of zelligea material have, which is enclosed by a shell formed from two elements, as well as profiles, one of which Part is enclosed in the soul and another part protrudes outside the shell, indea it is generally space runs between the two elements of the shell, the latter being part of the profile serves to effect the connection of the plates with one another or between the plates and the posts.

In these plates and posts according to the invention, the shell enclosing the core of cellular material can consist of two half-shells of matching shape and dimensions, but it can also consist of two different parts, in particular one part, one side and the strips of the plate encloses, and a flat part that is in contact old the other side of the plate.

The elements or parts forming the shell can be connected to the core of cellular material during the manufacture of the plate or the post. Sit can also be connected aittels the profiles together · The shell may be made of a laminate of aittels Hari and fibers, in particular glass fibers.

S09883 / 1346

The material for the cellular soul can be organic Use cellular products, especially foams of the Polyurethane that adheres well to the elements enable the shell. Since this attachment deals with which can diminish in time, especially in warm and humid atmosphere, it is beneficial between the Elements of the shell and the foam provide a connecting layer, which is made up of a thin skin an adherent material that is associated with each of the is compatible with both materials. This thin skin can, for example, be painted with polyurethane or rubber adhesives be. Suffice it to the inner surface of the Elements of the shell with the help of these adhesives or paints to coat and possibly the formed Let layer dry before expanding of the foaming material begins.

One can also see the foam sticking to the elements favor the shell and the good properties of this Maintain adhesion after aging by having a Makes staining with short glass fibers. This operation for example, it can be executed right now the manufacture of the. Shell when this fabrication in touch with the foam just before the hardening of the Resin takes place. If you manufactured with the machine Using shells, & s can be difficult to surface having optical fibers falling into the eyes; you can then do the flocking after fabrication make the shell by using a § * jigx most suitable /

th adhesive, such as a rubber adhesive, or with a coating of polyurethane.

A very substantial improvement in the mechanical quality of the panels can also be achieved by using providing an intermediary material of some thickness between the foam and the shells. This material should have mechanical properties between those of the materials used for the shell and the soul lie. This design of the plate or the post enables the reduction of the shear stress

voltage ^ that in the case of mechanical bending stresses Interlayer are present. The intermediate and / or mediating material can also have properties with regard to thermal expansion between which the main components lie. In this case one also reduces with temperature changes the visual tension in the intermediate layers.

This mediating material can consist of a polyurethane foam of high density, on the order of about 300 kg / m 2. This polyurethane can for example be thrown into the interior of the bowls by atomization. Then the connection is made two half-shells and foaming, as previously described, with the help of a polyurethane cream, the densities in the Achieving a magnitude of 40 kg / m is permitted. This mediating material makes it possible to get the soul out of the cellular product to connect with the shells, whereby

909883/1346

both of them can moreover be produced with the effect of foaming between the two preceding ones Materials.

This mediating material can also consist of a composite Product exist, for example a polyurethane reinforced with glass fibers. It can possibly have powdery supplementary fillers. You can also use an epoxy resin concrete with low resin content and high filler content.

The profiles can have a Η cross-section, with one of the legs of the H being arranged between the shell and the core made of cellular material, while the other leg is arranged outside the shell. The connection between successive structural elements is advantageously achieved by gluing or casting a flexible connection between adjacent profiles.

According to another embodiment, the connection between successive elements is mechanically effected by means of the profiles which nest one inside the other.

According to another feature of the invention, the profiles have in their inner part the core of zelligea mate rial through a hollow rough "for laying i of sewage or electrical cables.

909883/1346

According to another characteristic of the invention, the posts have a structure similar to that of the panels are, in addition, a hollow central core, which is designed as a round or square metal tube can be. This soul preferably absorbs mechanical forces from the shells due to the higher Value of their modulus of elasticity. This soul also allows anchorages to be formed easily at the ends of the posts.

Further features and advantages of the invention will become apparent from the following description, the its Reproduces embodiments which are given as non-limiting examples

In this description, reference is made to the drawing. In this show:

In the embodiment of FIGS. 1 and 2, each plate has a core 1 made of rope material, which is completely encased τοη two half-shells 2 and 3. Each plate has also a profile in Η-shape, one of the legs 4 in the

909863/1346

Soul 1 and its other leg 5 is arranged outside the shell. The crossbar 6 of the H occurs through the shell in the space between the half-shells 2 and 3.

When attaching a plate, its profile is compared to the profile of the next plate and the connection between these plates is achieved by means of a ™ flexible connection 7 between these profiles

is glued.
I) ^

The post 8 also comprises a core 9 made of cellular material and two half-shells 10 and 11. A connecting device is formed in the same way as that of the plates. In this way the post can be connected to the adjacent panel.

The outer part of the profiles can have ribs 13, protrusions or the like. have to facilitate the attachment of the connections 7. These connections consist of a Elastomer that adheres to the profiles. They can consist of two parts leaving a space in between, in which one introduces an insulating material 14 to prevent the formation of thermal bridges through the connections to avoid.

The connections can be limited on the outside in the height of the profiles, as can be seen in the upper part of FIG is. But you can also use the profiles against

the sehale to be elongated, as is the case in the lower part this figure is shown.

Fig. 3 shows another form of a profile 15 with an inner cavity 16, which is particularly suitable for laying of electrical lines' is used.

In the embodiment according to FIG. 4, the profiles allow a mechanical connection between the plates or between the plate and the post. These profiles have different shapes, depending on the edge of the plate one looks at. They have father profiles 17 on one side and mother profiles 18 on the other. These profiles are nested within one another. In this figure, at 19 is a thermal insulator between the Profiles and shown at 20 a sealant. This means should be pliable and on the half-shells cling. It can, for example, a silicone, a polyurethane or the like. be.

Fig. 5 shows an arrangement in which the shell consists of a part 21, one of the sides of the plate and its Belts completely enclosing, as well as from a flat part 22 which covers the other side of the plate. The connection profiles have a part 23 in which the flat plate 22 fits, and a part 24 in which the part 21 of the shell inserts. They also have a mother part 25 and a father part 26, depending on which one Hand one is considered to connect two to each other

to effect the following plates. The tightness against moisture of the connection between the panels can be very simply be brought about with an elastomer that is poured between the two profiles during assembly and the space 27 between the parts 25 and fill in 26. The gap 28 that is left between two consecutive plates, can with filled with an insulating material.

The part 21 of the shell which is one of the sides of the plate forms, can be flat or have longitudinal ribs, as can be seen at 29.

The arrangements described ensure complete tightness between the plates on their two bands. To produce the end sealing of the panels, one can 6 use caps 30, which close the two ends of the plates from the inside or from the outside. These Caps also allow the top and bottom of the panels to be attached to the structure.

The tightness can also be achieved by means of a certain thickness of polyester concrete 32 or another similar concrete (Fig, 10 and 11). If the slabs are made in one size, you can attach them to the pieces of concrete shape separately and glue them to the ends of the polyester shells; one forms a closed volume that one then fills with look.

When the panels are made continuously and cut to length, cut the foam up to a certain depth and fills the cavity thus formed with concrete. Extension pieces 33 can also be used Plastic or galvanized sheet metal (Fig. 9) stick on. These extension pieces can have projections 34 as shown in FIG. 9 or grooves to facilitate attachment the connection. According to FIG. 11, the piece of concrete 32 can have grooves 32 *. It can also have ribs.

It is of particular interest in the manufacture of the Post lines to be provided for the laying of electrical cables. These lines 31 can be in a projecting rib of the post may be provided, as shown in FIGS. 7 and 8. They can be extruded from one There are plastic profiles that are glued to the inside of the shell during the manufacture of the posts. As can also be seen from these figures, the posts have a central hollow core 36, for example made of Metal.

According to FIG. 12, an anchoring between the Post 35 and plank 37 produce by means of an expansion device which has a slotted sleeve 38, which is arranged in the core 36 of the post. This sleeve is conical at both ends and is in contact on the one hand with an »internally smooth conical part 39 and on the other hand with a conical part 40,

909883/1346

which is internally threaded. A threaded mandrel 41 is supported on the board and screws into it Part 40 and thereby causes the elongation of the slotted sleeve 38 and thereby the attachment of the post the hall.

In the variant according to FIG. 13, the core 36 of the post is extended by a part 36a that extends over the Board 37 protrudes. This protruding part has two openings 42 into which a wedge 43 is inserted and thereby anchoring the post to plank 37. A cap 44 closes the part 36a at the top and is attached to the board. A connection can be seen at 45 in this figure which is provided between the post and the lower surface of the board. This connection is made in the groove 32 * of the piece 32 Polyester concrete attached.

In the embodiment according to FIG. 14, the post has parts 32, 32a made of polyester concrete at both ends and is secured between the plank 37 and the plank or floor 46 by a shaft 47 which is coaxial to the post is. This shaft is attached on the one hand with its head 49 to an anchorage 48 which is in the ground is provided, and on the other hand it is supported on the board 37 by a sleeve 50 which is firmly connected with a cup 51, a screw nut 52 being screwed onto the shaft and a spring 53 being screwed onto the cup

presses; At the ends of the post are links 54 and 55 provided.

The posts that are used for the formation of walls and vertical partitions alternating with the panels can have different shapes. In particular from The interest is in cross shapes that allow easy connections between walls and walls with a single post model enable outer post. The circular shape of the posts also enables partition walls to be built at any angles to each other. In this case, the bands of the plates are expediently concave according to FIGS Figs. 15 and 16, which show a series of plates, such as 56, with concave bands, which are connected to posts, such as 57, connected by circular shape.

A likewise advantageous arrangement is shown in FIGS. This arrangement includes plates 58, whose bands are beveled. This makes it easy to with a single type of element both a continuous wall (Fig. 17) and a connection between one another create other right-angled walls. The bands of the plates can possibly be hollow. You can create profiles, such as 59, have, for example, made of wood, polyester concrete, plastic material, etc. The posts can be made of a metallic Drill 60 exist, and a connection 61 may be provided between the post and adjacent ones Plates (Fig. 17).
