Description

Methods relating to compressed matrix structures, such structures and uses of such structures

The present invention relates to methods for attaching devices to a compressed base structure, such as fibreboard or the like, by compressing a base material between compression members and subjecting said material to produced by the hardening process. The invention also relates to a compressed matrix structure, such as fibreboard or the like, wherein said structure comprises a fibrous matrix material which hardens during compression to form a firm structure, and to such The special use of the structure.

Fibreboards and similar structures are known, wherein such structures comprise a matrix material such as wood or similar fibers substantially surrounded in a bonding composition such as glue, cement, gypsum or the like. Such panels or certain other embodiments of structures such as wainscoting or the like are made by feeding a quantity of matrix material, including a suitable bonding material, between compression members, which The pressing members are usually pressing plates or the like, and then, at least one of said pressing members is moved towards the opposite one, thereby compressing the intermediate matrix material to 1/3 of its original size in at least one direction to 1/4. Simultaneously, or in combination with this pressing step, the bonding component in the matrix material is hardened. After release from said pressing member, the matrix material forms a structure of the desired shape, most usually a fibreboard, which can be used as a base material for further production steps.

Fibrous structures, especially panels and edging elements fabricated as described above, are widely used in construction applications. When connecting such a structure to another structure of relatively large size, glue, nails or screws are usually used as fastening means. However, there is often also a need to fasten different types of smaller devices to such plates. For this purpose, usually nails, screws or similar fastening means are forcefully driven between the fibers of the structure, or these fastening means are inserted into the fibers of the structure. The overall length of these fastening means must be adapted to the thickness of the structure so as not to penetrate the structure completely and thereby damage its opposite sides. This feature often limits the use of conventional fastening means or, as a result, requires the plate to be thicker than necessary in order to obtain adequate installation force. In some cases, fully penetrating bolts and nuts are used so that these pieces can be clearly seen on both sides of the structure. In most cases, this is considered a surface defect and special attention must be paid to it later.

For fastening hooks or the like of panels sometimes expansion devices are used which pass through a hole in the panel and expand inside said hole and/or on the back of the panel. Such means can be used in cases where the opposite side of the plate or the like does not simultaneously constitute a second front surface.

In the house building industry, a modern method of making concrete structures is known, in which a formwork of opposing slabs is connected to each other and then concrete is poured into the space between said slabs. Such shaped panels are not removed after the concrete has cured, but are left in place, so that they form a good outer surface of the concrete. Because the concrete is subjected to considerable hydrostatic pressure exerted on the form before the concrete cures, the slab so formed must be securely fastened. The usual through fastening means and the corresponding known locking means cannot be used, since the outer sides of the formwork must be kept substantially inaccessible and the formwork in its entirety. For this purpose, until now special tongue-shaped fastening means were usually used, which were fastened to the inner side of the formwork with screws or the like. Since the screws must withstand considerable forces, they must be relatively long, so that the thickness of the plate must be as high as 25 mm or more. This is costly, and the installation of the fastening means is laborious, however, does not give an overall reliable connection between the opposing plates.

The object of the present invention is to overcome these disadvantages of the prior art and to give a rather new concept for mounting external devices and the like to fibreboard or other compressed structures made of compressed matrix material without It is necessary to use special fastening means which have to be fitted by hand or at least have to be fitted separately to the plate.

The idea of the invention arises from the practice that by mounting the separate means on the compressed base plate during the manufacture of the plate a much simpler and more reliable mounting can be obtained than with any external means. This can easily be achieved by placing special elements between the pressing elements of known pressing means for compressing the matrix material during the production of the panels. The special member is arranged between the pressing members before the compressible matrix material is introduced between the pressing members. Said special part is preferably a tongue-shaped mounting means which extends into the base material and correspondingly to the surface parts which are in the immediate vicinity of the pressure part during production. In a finished panel or similar structure, said surface portions are on its surface and can be bent or raised to a protruding position where said surface portions are actually formed by the usual panel The surface stretches outward.

The invention is more precisely described in the appended claims. Thus, in addition to the methods known in the introductory part, the method of the invention comprises the steps of providing at least one separate piece of deformable material comprising at least one surface portion and correspondingly at least one mounting The mounting portion, at least at its base portion, is directed towards the interior of the pressurizing device at an angle relative to the surface portion. Preferably, at least a first portion of said mounting portion extends in a substantially normal direction with respect to said surface portion, and an outermost portion of said mounting portion is slightly offset from said normal direction. One or more such separate elements are arranged substantially directly on the surface of at least one of said pressure elements, and said matrix material is then introduced between at least two of said pressure elements. When said pressure members are moved towards each other in a manner known per se, so as to compress said matrix material between them to its final dimensions, said mounting portion will be securely fitted in said mounting portion. Made on the base material inside the compressed structure.

The compressed matrix structure of the present invention comprises at least one separate piece which is embedded in at least one surface of said structure during the manufacture of said structure in such a way that at least one of said separate pieces is preferably The tongue-shaped or helical mounting portion extends at an angle into the base material before it is pressed, and a surface portion of the member extends along the surface of the structure. As a result of the compression of the base material, this material will firmly surround the mounting part and provide a strong connection between the part and the inner material of the fabricated structure. Because the mounting portion will extend into the base material at an angle, the portion will be exposed to any internal forces acting in the material. Such forces and internal movement of the matrix material will advantageously slightly deform at least a part of the mounting portion during the compression step and thus further enhance its mounting to said matrix material.

Said surface portion of said separate member extends substantially along and is flush with at least one surface of said structure, from which position it can be bent to extend at a position offset from said surface. Said angle between said mounting portion and said surface portion will determine in an advantageous manner the approximate position at which said bending occurs, and thus can easily predetermine the position of the projection of said surface portion in its direction. The exact position of the base in the outwardly bent state, this property is important when the surface portion is used for fastening purposes. The preferred arrangement of the mounting portion to extend at least somewhat substantially orthogonally with respect to the final surface of the structure will further facilitate this performance while preventing any breakage of the surface in the vicinity of the portion.

Particular inventive uses of the method and apparatus of the present invention include the use of compressed matrix panel structures as defined above in the construction industry as formwork.

The invention will now be described in more detail, by way of example only, with reference to some preferred embodiments shown in the accompanying drawings, in which:

Figure 10 shows an embodiment in relation to a substantially three-dimensional fibreboard structure, namely a cornice; and

Figures 11a and 11b show a vertical section of a particular arrangement especially suitable for use in formwork.

Referring now to Fig. 1, a formwork known from the prior art comprises two opposite plates 1, 1a forming a space 2 between them for holding cement or similar material in a semi-liquid state, these The material is adapted to be cured to form a rigid structure. In order to maintain the distance between said panels 1, 1a and to withstand the hydrostatic pressure of the cement before it hardens, the formwork includes supports 3 connecting the panels 1, 1a to each other. Said support 3 is also suitable to include fixings for reinforcing rods, pipes or the like 4, which are placed inside the concrete. The support 3 may comprise parts 5 , 5 a connected to each other, see FIG. 2 .

According to the prior art, the support 3 or similar 5a is attached to the inner surface 9a of the plate 1, 1a using screws or similar attachment means 6 which pass through the flanges of the support The portion 7 stretches and extends into the interior 8 of said plate 1, 1a. Because it is desirable to keep the outside surface 9 of the plate clean and not disconnected, the length (L) of the connecting means 6 must not exceed the thickness (T) of the plate 1, 1a, which may occur if the plate is not of sufficient thickness. As a result, the installation strength will not be satisfactory. Consequently, the thickness (T) of the plates 1 , 1 a must be adapted to the technically necessary length (L) of the connection means 6 , often resulting in an unnecessary heavy plate construction.

Now, referring to Fig. 3, the present invention brings a very new concept for attaching any kind of device to a plate or similar structure, therefore, this device is also included in the formwork shown in Fig. 1 A piece used as support 3. The device according to the invention comprises a special separate part 10, usually made of suitable thin material such as sheet metal, wire or the like, which are deformable, i.e. they can be bent and raised at least once , without breaking. According to FIG. 3, said separate member 10 comprises at least two functionally separate parts, namely a suitable tongue-shaped mounting part, which is generally indicated by reference numeral 11, and a surface part 12, which can For any purpose, e.g. as a fastening device, etc. Said mounting portion 11 is used to mount the separate element 10 to a surface 9a of any such compressed base structure made, for example a fibreboard element 1, 1a, an edge element or the like, such as According to the introductory part of claim 1 it is known per se. This mounting is such that the surface portion 12 of the member 10 will lie close to the surface 9a of the compressed base structure and, in practice, is usually slightly embedded in it. According to a preferred embodiment, said mounting portion 11 of said separate element 10 is adapted to comprise at its extreme end one or more tongue-like or corresponding formations 13 which may comprise a special surface structure 14 , ie hatched portions etc., are used to improve the mounting to a compressed base structure such as the base material 16 of the fibreboard member 1, 1a. It can be observed that the outermost end of said surface portion 12 which is located opposite said mounting portion 11 may have any suitable form or shape. The shape shown in FIG. 3 is just an example.

Mounting portion 11 is preferably of tongue-like configuration which is particularly suitable for flexing during compression. However, any other suitable shape is also possible, as long as this shape allows it to be completely embedded in the matrix material and achieves a secure fit of the separate piece 10 in the inner material of the panel 1, 1a.

The technical characteristics of this embedded installation can be clearly seen from Figure 4a and Figure 4b. According to the method of the present invention, one or several such separate parts 10 are arranged next to the pressing part 15, usually directly on the top surface of the lower part of a pair of such parts 15, 15a, or for example in a stack of such parts. On the top surface of each successive piece in pieces 15 to 15b. Figure 7 shows an arrangement in which such pressing members 15 to 15b in the shape of substantially thin sheets (typically about 3 mm in thickness) and alternately arranged base materials 16 are stacked on a per se known Between the actual pressurizing device (not shown). Said separate part 10 is provided before feeding uncompressed matrix material 16 into the space above said lower pressing part 15 . At this point (see FIG. 4a ), the tongue mounting portion 11, including any tongue or similar structure 13, will extend into the base material 16 approximately orthogonally with respect to the pressure member 15, at least in such a The outermost part of the tongue or similar structure 13 is preferably separated by a small distance D, which is set to facilitate the initial deformation of the mounting part.

According to known manufacturing methods, the fibreboard 1, 1a or similar structure will now be made by pressing at least one of the opposing pressing members 15 against the other, thereby compressing the intermediate matrix material 16 to its original state. about 1/3 to 1/4 of the thickness is compressed and, substantially in the same step, the matrix material is hardened, as is known per se.

When the pressing members 15, 15a are pressed together on both sides of the matrix material 16 (see the vertical arrows in Fig. 4a), the matrix material will be compressed, and simultaneously, according to the present invention, in the matrix material 16 Under the effect of the applied internal pressure, the mounting portion 11 and in particular any tongue-like structure 13 will bend slightly (see curved arrow in FIG. The surfaces of the mounting part 11, especially the tongue-like structure 13 (see FIG. 4b ) are closely in contact with each other. This bending can be facilitated by making some or all of the mounting portion 11 slightly curved, particularly any of its outermost end structures 13, wherein any adjacent structures 13 are preferably in the are bent in opposite directions so that when said material 16 is compressed they will stretch in opposite directions within the matrix material 16 . Under normal circumstances, however, the tongue does not extend through the structure onto its opposite side and will therefore keep the structure, eg the opposite surface 9 of the plate 1 , flat and free of defects. It can therefore be used directly as a final wall surface, eg in a formwork application, as described above.

Due to the stiffening of the matrix material 16, said tongue-shaped mounting portion 11 of said separate piece will now be firmly fitted into the matrix material 16, and thus to the compression structure such as a manufactured fibreboard 1 or the like. in. Such a mounting will in fact involve a much larger internal area of compressed base material than any possible screw 8 or similar fastening means, and therefore the mounting according to the invention is stronger than known fastening methods many. Since some parts of the portion 11, in particular any outermost end structures 13 thereof, will preferably after the compression step substantially extend in, for example, the generally planar direction of the plate structure 1, the structure can be made as compared to The corresponding structures are made in dimensions suitable for fastening with screws much thinner.

Referring now to Figure 5a, it shows a surface portion of a structure 1 made in accordance with the present invention, said structure comprising an additional or embedded surface portion 12 of a separate piece 10 on at least one of its side surfaces 9a. When the structure being made is a panel, it is easy to stack several such panels one on top of the other and transport them to a building site or the like, since the structure of the separate pieces 10 remains flat. of.

In the field, the surface portion 12 of such a piece 10 can now be easily detached from the surface 9a of the fiber structure 1 and bent, for example, into the protruding position shown in FIG. is appropriate for any other state. Now, the structure, for example according to the panel 1 shown in Fig. 5b, comprises a protruding portion 12 extending transversely to the panel surface 9a and fastened firmly to the inner material of said panel. Only a shallow mark 12a remains on the surface, which can be easily smoothed out with putty if necessary. In the case of applications where the direction of the protruding surface part is towards the interior of the structure, for example in formwork, any such smoothing work is not necessary.

The protruding member 12 provided by the present invention, which is securely fitted to the compressed base structure, can be used for many different purposes, some of which are temporary, such as in connection with the erection of a building, while some Some will be preserved, for example as future installation points for paintings or similar detailing in the final building. These projections can thus also be used, for example, in the furniture industry.

A preferred embodiment of the invention is shown in Figures 6 to 9 and is particularly suitable for use in formwork. Here, the integral connection of a plurality of separate protruding surface part elements to each other is suitable to form a row of fastening means which can extend substantially over the entire length of the panel structure. As is clear from FIG. 6a, such a piece 20 is suitably produced, for example, from a strip 21 of sheet metal, wherein on one edge of said strip 21 a continuous serrated portion 22 is punched out. Subsequently, the relatively longer sections are bent over and flattened (see FIG. 6b ), thus forming a continuous fastening section 23 corresponding to said surface section 12 according to the embodiment described above. The central tongue portion 24 is bent approximately 90 degrees (see FIG. 6c) to form a continuous mounting portion encased in the base material 16 of the panel to be produced. Said tongue portion 24 is preferably bent into a slightly curved shape, wherein successive tongue portions are inclined slightly in different directions, in order to facilitate a firm and secure fit into the base material 16 of the structure 1 . An uninterrupted lug-like formation 25 extends along the entire length of the unitary member 20 and connects the separate parts 23, 24 to each other. Of course, the successive mounting part 11 and surface parts 12, 23 can also be realized in an arrangement different from that in Figs. 6 to 8, which should only be regarded as an example.

Figure 7 shows how such an integral elongated piece is placed on a compression panel prior to feeding the matrix material 16 into it. As shown in Figure 7, a press function preferably includes pressurizing a plurality of superimposed base portions 16, 16a, 16b, each of which is provided with a lower press member 15, On the top side of 15a, 15b, these pressure pieces are suitably made of steel. Each base portion 16 , 16a , 16b suitably comprises a plurality of integral separate pieces 20 , 20a each of which is arranged on a respective underlying pressing piece 15 . In this way, up to 50 panels can be produced in one pressing operation, each panel 1 having a plurality of rows of protruding surface portions 23 or corresponding means arranged flat on one surface 9a, relatively The surface 9 is clean and smooth (see Figure 8a).

Arranging said protruding surface portions 23 flat, as shown in FIG. Parallel, and practically embedded in its surface 9a, due to the manufacturing method according to the invention. On the building site, the protruding surface portion 23 to be used is bent upwards, as shown in FIG. 8b. Due to the bending discussed above, the device can easily be bent upwards so that the lug-like structure 25 will also stretch in a direction perpendicular to the plane of the plate 1 , as can be seen in FIG. 9 .

FIG. 9 now shows how the plates 1 , 1 a made according to the embodiment shown in FIGS. 6 to 7 are particularly well suited for forming formwork as discussed above. Here, the protruding surface portions 23, 23a on the opposing plates 1, 1a are connected to each other using, for example, special sheet metal connecting clamp means known per se. These connection clamping means are pressed by overlapping tongue-like portions of opposite projections 23, 23a, wherein one or several locking connections 27 are to be formed. Introduction of the clamping means into the space 26 will form this space where the mounting portion 24 extends into the plate 1, 1a in opposite directions. Since the lug-like structures 25 are also bent upwards from the plates 1, 1a, there will be enough room for introducing concrete or similar material into the space 2 between the plates 1, 1a.

On the other hand, Figures 11a and 11b show in a simplified manner a formwork arrangement in which one or more reinforcing rods 4 are used to effectuate the connection between opposing plates 1, 1a in the formwork. This embodiment of the invention comprises one or preferably a plurality of elongated holes 35 provided in the cooperating flange-shaped supports 3, 3a. The supports 3, 3a are attached to the boards 1, 1a using mounting portions 11 provided on the supports 3, 3a, respectively. According to this embodiment, reinforcing rods are arranged through the intersecting portions of said holes 35 in said supports 3, 3a. Said holes 35 respectively comprise an elongated main part and semicircular parts 36 , 36 a , 37 , 37 a , said holes extending transversely for receiving said reinforcing rod 4 . Figure 11a illustrates an arrangement in which the two parts 37 (and 37a) arranged centrally on the upper edge of the hole 35 intersect at a location where a hook or the like (not shown) can be used to hold the The assembly consisting of opposing panels 1, 1a and telescoping supports 3 is raised. In this position, the reinforcing bar locks the member 3 in a position that minimizes the overall thickness of the assembly and thus facilitates storage of the assembly. On the other hand, Fig. 11b shows the situation before filling said space 2 between said panels 1, 1a with concrete or similar. In this position, said reinforcing bar 4 will drop into the recessed parts 37, 37a which are located in the lower part of said elongated hole 35 and nest said parts 1, 1a to the corresponding last A stretched position for the appropriate width of the structure. Such locations may be provided in a number of different wall thicknesses using a number of recessed portions 37, 37a.

Embodiments where the compressed base structure comprises a substantially flat fiberboard or similar structure have been primarily discussed above. However, it should be understood that the invention may also be used with structures of other shapes. Fig. 10 thus shows how the concept of the invention can be used for example in a cornice 33, in which case a fastening device according to an embodiment of the invention can be inserted into the slit between the wall and the ceiling. In this embodiment, the separate elements 30 are initially bent (shown in dashed lines) corresponding to the corners of the cornice 33, which cornice is produced in a manner known per se by pressing the fibrous material. On site, a tongue portion 31 of said member 30 is then bent into the position shown in solid lines in FIG. 10 . In this embodiment, the outermost portion of said tongue portion 31 preferably includes a hook formation 32 for securing the tongue portion to a wall panel 1 or the like. In this embodiment, the mounting tongue 34 of the separate piece 30 is also bent during the pressurization of the matrix material constituting the body of said cornice 33 .

In some cases it may be desirable to provide projections according to the invention on both sides of the panel. In this case, it is suitable to temporarily fix the flat surface parts 12, 23, 31 to the respective pressing parts with a weak glue, double-sided tape or the like, in order to Keep them in their place. In these embodiments of the invention, it may also be desirable for at least one panel surface to be relatively flat, although it may be desirable to have integral protrusions at specific locations. In this case, the special element according to the invention can be arranged with a portion of flat thin material, for example paper or the like, for the manufacturing step between the separating element and the pressing element. In the final board, this thin material will form a smooth, flat outer surface which can easily be painted or wallpapered. However, such locations covering the protrusions can be easily identified by visually observing the surface structure prior to coating and even later by using eg a metal detector or simply by tapping on the surface.

Typically, the protruding surface portions 12, 23, 31 will be flush with the surface of the structure and, in fact, somewhat embedded in it. Usually, it is easy to disengage the outer end of the part and raise the protruding tongue or the like 12, 23, 31 upwards. To allow easy gripping of the outer end, it may comprise a suitable formation, such as a hole 17, or an inclined notch 18, which constitutes a mounting site for a suitable lifting tool. In some cases it may also be advantageous to carefully facilitate the raising step by arranging so that the surface part is free and its edges are not embedded in the matrix material to any extent. Achieved. This can be done by arranging a small piece 19 of firm sheet material between said surface portion 12, 23, 31 and the base material, ie on the upper side of said surface portion, before introducing said base material 16 so that it Stretching on the pressure member 15 (see FIG. 4b ) is easily achieved.

Above, certain preferred embodiments have been described, by way of example only. It should be understood that the present invention will not be limited to these examples and embodiments, but it will also include other embodiments and modifications within the scope of the appended claims.

Therefore, other embodiments may comprise special formations 14, 28, 32 provided on said tongue-shaped mounting portion 11, its ends 13, 23, 34 and/or on said surface portions 12, 23, 31, The purpose is to facilitate the attachment of the device to the base material 16 and the attachment of the different separate pieces to the surface parts 12, 23, 31. These structures 28, 32 may include, for example, holes, hooks, indentations or similar structures. It can also be observed that the embodiment in which the support 3 is placed for example formwork used in the building industry should be seen as an example only, and the invention is not limited to these only, but generally includes any other kind of Mounting of parts comprising at least one part 12, 23, 31 to a basic structure 1 made of compressed matrix material, the parts having at least one part of a generally planar appearance during their manufacture, during the manufacturing step This part can then be raised at any angle with respect to the general surface of said basic structure 1 and can be used as a mounting means for attaching any kind of device to said basic structure 1 .
