The insulation material supply device 3 shown in an enlarged scale in FIG. 2 is for supplying insulating plates I, interconnecting the insulating plates I to an insulating material web K, and severing the insulating body W from the insulating material web K. The insulating material feeding device 3 has an insertion device 19 on, which determines the formation of the insulating body W of the component B certain insulating plates I according to the direction of the arrow P4 of the production line XX of the system laterally. The insertion device 19 consists essentially of two working cylinders 20, the piston rods are moved in accordance with the double arrow P5 and are provided at its end with a pressure plate 21. In the production line XX is a conveyor belt 22nd arranged, which is drivable by means of a conveyor drive 23 in the production direction P1 and the insulating plate I advances in this direction along the production line XX. With the aid of a transversely displaceable stop frame 24, the feed movement P4 of the insulating plates I is limited and determines the position of the insulating I in the production line XX exactly. On the inlet side of the conveyor belt 22, a feed device 25, for example a working cylinder, is arranged. The piston rod of the working cylinder 25 is movable according to the double arrow P6 and provided with one of the end face of the insulating I I adapted pressure plate. With the aid of the feed device 25 located on the conveyor belt 22 insulating plate I 'is additionally advanced according to the arrow P1 to move the insulating I' relative to the already formed Isoliermaterialbahn K and thus the insulating I 'positively and non-positively with the end of Isoliermaterialbahn K and produce an endless, continuous insulating material web K. Under a positive connection, a compound of the insulating I, I 'understood that at the junction between the two insulating I, I' has neither gaps nor lateral projections. A non-positive connection means a connection of the insulating plates I, I 'in which the connection point does not open under tensile and compressive loading.

For connecting the insulating plates I 'with the already formed Isoliermaterialbahn K, a connecting device 26 is disposed in the output region of the conveyor belt 22. The connecting device 26 is displaceable according to the directions of the double arrow P7 transversely to the production line XX and parallel to the production line XX corresponding to the directions of the double arrow P8. According to this embodiment, insulating panels I, I 'are used, which have flat end faces F on their narrow sides. To produce an endless insulating material web K, the insulating plate I 'is formed, for example, by heat welding with the aid of a heating device Connecting device 26 connected to the insulating material K. The heating device essentially consists of a heating plate and a heating transformer serving for heating the heating plate. The endless insulating material web K is produced in the following manner: The insulating plate I 'located on the conveyor belt 22 is advanced by means of the feed device 25 according to the arrow P6 until the insulating plate I' abuts the heating plate abutting the end face of the insulating material web K. , The heating plate is then heated with the aid of the heating transformer until the adjacent end faces of the insulating material K and the insulating I 'are softened. The hot plate is then rapidly pulled out of the gap between the insulating plate I 'and the insulating material web K in the corresponding arrow direction of the double arrow P7 and the insulating plate I' with the aid of the feed device 25 according to the production direction P6 slightly advanced to press the heated end faces against each other and in order to weld the insulating plate I 'to the insulating material web K and thus to connect it positively and non-positively. Since the insulating material K is gradually conveyed in the connection process by the conveyor belt 22, in time with the entire production plant according to the production direction P1, the connecting device 26 is also gradually moved during the heating according to the corresponding arrow direction of the double arrow P8 and after pulling out the hot plate in the appropriate Opposite direction of the double arrow P8 moved back to the starting position.

According to a further exemplary embodiment, to produce an endless insulating material web K, the insulating plate I 'is connected to the insulating material web K by gluing with the aid of a connecting device 26 designed as an adhesive device. The adhesive device has, for example, a spray nozzle together with a storage container which is filled with a suitable adhesive. The glue must be used to glue the material of the insulating panels I, I 'be suitable and have a tuned to the production speed drying time to ensure a secure connection of the insulating plate I' with the insulating material K. The adhesive device is for spraying the adhesive on the end face F of the insulating I 'in the horizontal direction and in the vertical direction movable. In order to accelerate the application of the adhesive, several adhesive devices can be used simultaneously within the scope of the invention. Within the scope of the invention it is also possible to spray several insulating panels I 'simultaneously with adhesive. The endless insulating material web K is produced in this embodiment in the following manner: Immediately before the supply of the insulating plate I in the production line XX an end face F of the insulating plate I is provided with adhesive. The insulating plate I 'is inserted with the help of the insertion device 19 first according to the direction of the arrow P4 laterally into the production line XX and stored on the conveyor belt 22. Subsequently, the insulating plate I 'with the aid of the feed device 25 according to the production direction P1 slightly advanced to press the adhesive face of the insulating I' against the end face of the insulating material K and thus the insulating I 'with the insulating material K form and to connect non-positively.

In the context of the invention, the insulating plates I, I 'at one end face F a groove and at the other opposite end face F' have a spring, groove and spring are formed such that the spring of an insulating plate I positive and non-positive in the groove a following other insulating I 'fits. Due to the relative movement corresponding to the direction of the arrow P6, the spring of the insulating plate I 'engages in the groove of the terminal element of the already formed Isoliermaterialbahn K. The grooves and springs are matched in their design to one another, which creates a positive and non-positive clamping connection, both the Escape the insulating panels I, I 'as well as their fixed Ensuring connection with each other. The connecting device 26 is in this embodiment out of function.

In the context of the invention, it is possible to provide the tongue and groove provided with end face of the insulating I, I 'additionally with an adhesive to ensure a secure connection of the insulating panels. The adjacent to form the Isoliermaterialbahn K end faces of the insulating plates I, I 'may be provided in the invention with other positive and non-positively cooperating Klemmverbindungselementen that are formed, for example, dovetailed.

It is understood that the illustrated embodiments can be varied in the context of the general inventive concept variously, in particular with regard to the configuration and execution of the devices for connecting the insulating plates I, I 'to form an endless insulating material web K. When using appropriate adhesives, both the end face F of the insulating I, I 'and the end face of the insulating material K can be provided with adhesive.

Furthermore, it is possible within the scope of the invention to provide one or both of the flat end faces F of the insulating panels I, I 'to be joined with a self-adhesive film. The film can already be applied in the manufacture of the insulating panels I, I 'and is expediently protected by a peelable film.

To the conveyor belt 22 includes a over the entire production line X-X extending conveyor, for example, a conveyor chain 27 which is driven according to the production direction P1 and the insulating material K and the insulating body W in the production line X-X intermittently move according to the production direction P1.

The insulating material supply device 3 has a cutting device 28 for the insulating material web, which correspond to the directions of the double arrow P9 transverse to the production line XX and parallel to the production line XX according to the directions of the double arrow P10 is displaceable. The cutting device 28 separates the insulating body W from the insulating material web K in a selectable length and has at least one cutting drive 30 drivable by means of a cutting drive 30. To increase the cutting performance, a further cutting drive 29 'together with cutting disk 30 can be used. The cutting device 28 is moved along with the feed movement of the conveyor chain 27 in accordance with the production direction P1 during cutting and returned to the initial position after the cut, these movements take place in accordance with the double arrow P10. The retraction into the cutting position the corresponding retraction from the cutting position is carried out according to the double arrow P10.

Within the scope of the invention it is possible to use other cutting methods and devices for separating the insulating body W from the insulating material web K. These methods and devices must be tailored to the material properties of the insulating materials and ensure that the cut as smooth as possible edges and does not affect the material of the insulator in its properties, for example, is melted. In particular, can be used as a Isoliermaterialbahn-cutting device transverse to the insulating material K movable and heatable by means of a heating transformer cutting wire.

Since the cutting device 28 is also conveyed stepwise in the cycle of the entire production plant according to the production direction P1 when cutting the Isoliermaterialbahn K by the conveyor chain 22, the cutting device 28 is also moved during the cutting stepwise according to the corresponding arrow direction of the double arrow P10 and after the completion of the cut moved back in the corresponding opposite direction of the double arrow P10 in the starting position. The conveyor chain 27 conveys the insulating body W separated from the insulating material web K in accordance with the production direction P1 in the subsequent processing equipment of the plant.

Since the conveyor chain 27 must not extend into the trajectories of the connecting device 26 and the cutting device 28, the insulating material K is supported in this area of at least two support members 31, which by means of a working cylinder corresponding to the double arrow P11 from the movement path of the connecting device 26 and the cutting device 28 can be moved.

The insulating body W is of several rows of several, in the vertical direction at a mutual distance one above the other arranged straight ridge wires S, S 'interspersed. The webs S, S 'are at their two ends respectively to the corresponding longitudinal wires L, L' of the two wire mesh mats M, M 'and protrude with a supernatant E, E' slightly laterally beyond the longitudinal wires L, L 'out to a ensure safe welding with the corresponding longitudinal wires L, L 'of the wire mesh mats M, M'. As the exemplary embodiment of the component B shown in FIG. 8 shows, the bar wires S, S 'are each welded to the longitudinal wires L, L', wherein, as shown in FIG. 7b, all the bar wires S1, S1 'are along a longitudinal wire pair L1, L1 'lie in a web wire plane ZZ common to the longitudinal wire pair L1, L1' and the sense of direction of the web wires S1, S1 'changes zigzag in the plane ZZ, so that a truss-like arrangement of the web wires S1, S1' is formed. The respective angles of the webs S1, S1 'to the longitudinal wires L1, L1' are selectable. In the case of an upright component B, a plurality of web wire planes Z-Z extend horizontally, with spacing parallel to one another, ie. the ridge wires S, S 'form in the insulating body W and thus also in the component B to be produced a matrix-like structure, which gives the component B the required rigidity. The entry angle at which the webs S, S 'are introduced into the space between the two wire mesh mats M, M' is adjustable by pivoting the web wire feeder 6, 6 'according to the double arrows P13 (Figure 6) the two web wires S and S 'to the wire mesh mats M, M' value wise equal but are chosen with different signs in order to achieve the truss-like stiffening of the component B.

The material and the structure of the insulating body W must be such that the insulating body W, the web wires S. in the subsequent, take place in the direction of production P1 onward transport in position within the insulating body W immovably fix. The number and the entry angle of the webs S, S 'in the web wire planes ZZ and the mutual, vertical distances of the web wire planes ZZ is selected according to the static requirements of the component B.

In some applications, it may be necessary to make the insulating body W of the component B of such hard materials that it can not be penetrated by the ridge wires S, S 'without deformation of the same. For example, hard plastics, such as polyurethane, lightweight concrete provided with expanded or foamable polystyrene as a lightweight aggregate, gypsum plasterboard or cement-bonded pressure plates containing waste plastics, wood chips or wood shavings, mineral or vegetable fibrous substances, can be used. In these cases, each web wire feeding device 6, 6 'each preceded by a Vorstechvorrichtung 34, 34', which, as shown schematically in Fig. 6, in the insulating body W corresponding channels C, C 'for receiving a respective web wire S, S form ,

The number of lattice engagement recesses 64 is chosen according to the transverse wire pitch of the wire mesh mats M, M 'such that the transverse wires Q, Q' of the wire mesh mats M, M 'are reliably detected by the transport disks 62 and the slip-free feed of the wire mesh mats M, M' is guaranteed , As a result of the inclination of the shafts 58, the transport discs 62 engage each advancing element 17, 17 '; 18, 18 'not only on one, but on a plurality of cross wires Q, Q' of the wire mesh mats M, M ', so that the tensile force is distributed over a plurality of wires and these are not too heavily loaded during advancement of the wire mesh mats M, M' , The inclination of the shafts 58 also ensures a continuous and slip-free further transport of the wire mesh mats M, M 'of successive components B, wherein the successive wire mesh mats may have distances in the joint area, for example, when separating pieces from the wire mesh webs G, G' arise.

The conveying elements 36, 36 '; 37, 37 'of the component conveyor 35 are analogous to the feed elements 17, 17'; 18 18 'of the wire mesh mat conveyor 16 constructed. Only the transport disks 66 illustrated in FIG. 4b had lattice engagement recesses 64 of lesser depth. The feed rollers 10, 10 'for the wire mesh webs G, G' have substantially the same elements as the feed elements 17, 18 of the wire mesh mat conveyor 16 shown in Fig. 3. The only difference is that, as shown in Fig. 4b , the lattice engagement recesses 64 of the transport discs 66 are substantially deeper so that they have pointed teeth 67. This shaping of the teeth 67 ensures that the teeth 67 reaching from the side into the non-guided wire mesh web G, G 'reliably grasp the transverse wires Q, G' of the wire mesh webs G, G 'and advance the wire mesh webs G, G' without slip.

It is possible to manufacture with the system according to the invention components B in which the wire mesh mats M, M 'different structure, i. have different longitudinal wire pitches and / or transverse wire pitches and different diameters of the longitudinal wires and / or transverse wires. However, the various transverse wire pitches must be integer multiples and may be 50, 100 or 150 mm, for example. Another limitation is that it must be ensured that the webs S, S 'can be positioned so that they can be securely welded in spite of these different wire divisions and wire diameter with the longitudinal wires of the two wire mesh mats M, M'.

It is possible to produce with the system according to the invention components B, in which one and / or both wire mesh mats M, M 'project beyond the insulating body W at one or both sides parallel to the production direction P1 sides. To achieve this, either the driver 57 are raised or extended, or the conveyor track of the conveyor chain 27 raised so that the lower, parallel to the production direction P1 extending side surface of the insulating body W is raised accordingly, whereby one and / or both Wire mesh mats M, M 'form the desired supernatant on this side. The conveyor track of the arranged at the top of the insulating body W upper conveyor chain 27 'must be lowered accordingly or the driver 57' lowered or extended accordingly.

For the manufacture of components B, in which the insulating body W project beyond the two wire mesh mats M, M 'on one or both sides or sides running parallel to the production direction P1, the conveying path of the lower conveyor chain 27 is lowered and optionally the conveying path of the upper conveyor chain 27 'raised so that the lower and possibly the upper, parallel to the production direction P1 extending side surface of the insulating body W relative to the wire mesh mats M, M' is lowered or raised accordingly, whereby the insulating body W, the two wire mesh mats M, M 'at one or surmounted on both sides with the desired supernatants.

The continuous production of the components B by means of the installation according to the invention preferably takes place in such a way that the wire mesh mats M, M 'of successive components B are separated from each other only by a negligibly narrow parting line between the longitudinal wires of successive wire mesh mats M, M' and also the corresponding insulator W associated therewith successive components B follow each other without appreciable gaps.

In the context of the invention, however, it is also possible to produce components B in which one and / or both wire mesh mats M, M 'project beyond the insulating body W at one or both sides perpendicular to the direction of production P1. If one or both wire mesh mats M, M 'should project beyond the insulating body W on both sides, the insulating bodies W of adjacent components B are fed by the conveyor belt 22 with appropriately selected distances to the production channel 2 and fed there with these mutual distances. When using an endless insulation material web K must during separation the insulating body W a piece corresponding to this distance from the insulating material K are cut out. The two joints between the wire mesh mats M, M 'successive components B are either exactly opposite or laterally offset from each other.

For the manufacture of components B, in which the insulating bodies W project beyond the two wire mesh mats M, M 'on one or both sides perpendicular to the production direction P1, the wire mesh mats M, M' are advanced in the production channel 2 at a predetermined distance. To produce this selectable distance between the wire mesh mats M, M 'of successive components B is cut out of the endless wire mesh webs G, G' by the wire mesh mats cutting devices 5, 5 'in generating the wire mesh mats M, M' a distance corresponding portion. The size of the distance is limited by ensuring that the gaps between the wire mesh mats M, M 'of successive components B can be bridged by the inclined shafts 58 of the wire mesh mat conveyor 16 and the component conveyor 35 to slip-free Feed the wire mesh mats M, M 'successive components B to ensure.

In Fig. 5a, a wire mesh mat cutting device 5, 5 'is shown schematically, which performs a separating cut and thus continuously separated from the wire mesh web G wire mesh mats M, M'. The wire mesh mat cutting device 5 shown in FIG. 5a has a cutting bar 68 which, when the wire mesh web G is upright, runs in the vertical direction parallel to the wire mesh web G and is arranged on one side of the wire mesh web G. On the other side of the wire mesh track G is also a vertical, parallel to the wire mesh track G extending blade bar 69 is arranged. The cutter bar 68 is corresponding to the directions of the double arrow P23 and the cutter bar 69 corresponding to the directions of the double arrow P24, respectively towards the wire mesh G back and forth away from this. For severing the wire mesh web G of the cutter bar 68 carries a counter blade 70. The cutter bar 69 carries a cutting blade 71, which cooperates with the opposite counter blade 70 during the separation cut. In Fig. 5a, the counter knife 70 is already shown in its cutting position, while the cutting blade 71 is in its movement to the wire mesh web G. The cutter bar 68 and the cutter bar 69 are adjustable for positioning in and against the wireframe feed direction P3. It is possible to use, instead of a counter knife and a cutting knife, a plurality of counter and cutting knives in order to cut through either each longitudinal wire L of the wire mesh web individually or in groups.

In Fig. 5b, an embodiment of a wire mesh mat cutting device 5, 5 'is shown, which makes it possible to cut in a cutting operation of the wire mesh web G a selectable section whose length in the feed direction P3 preferably the distance between adjacent transverse wires, the so-called cross-wire pitch, or an integer multiple of the transverse wire pitch corresponds, at the same time a trimming of the longitudinal wire ends takes place. The illustrated wire mesh mat cutting device has a cutter bar 72, which runs in the vertical direction parallel to the wire grid track G and is arranged on one side of the wire grid track G with edgewise wire grid G. On the other side of the wire mesh track G is also a vertical, parallel to the wire mesh track G extending knife bar 73 is arranged. The cutter bar 72 is movable toward and away from the wire mesh path G in accordance with the directions of the double arrow P23 and the cutter bar 73, respectively, in accordance with the directions of the double arrow P24. For cutting out a portion of the wire grid G of cutting bar 72 carries two adjustable to the position of the transverse wires Q of the wire mesh G counter knife 74, wherein also the mutual distance of the two counter blade 74 to the length the herauszutrennenden section is adjustable. The cutter bar 73 carries two adjustable to the position of the transverse wires Q of the wire mesh track G cutting blade 75 whose mutual distance is adjustable to the length of herauszutrennenden portion, and which cooperates with the opposite counter blade 70 when cutting out a piece. In Fig. 5b, the counter blades 74 are already shown in their cutting position, while the cutting blades 71 are still in their movement to the wire mesh web G. The cutter bar 72 and the cutter bar 73 are adjustable for positioning in and against the wireframe feed direction P3. In the context of the invention, it is also possible in this embodiment, instead of a counter knife and a cutting blade to use multiple counter and cutting blades to separate out either the sections for each longitudinal wire L of the wire mesh G individually or in groups.

The web wire feeding device 6 shown schematically in FIG. 6 has a base plate 76 which carries a backstop 77, a guide rail 78 extending in the direction of the component B and a cutting device 79. On the guide rail 78 is a carriage 80 by means of a drive device, not shown, e.g. a working cylinder, crank mechanism, motor drive and the like, according to the double arrow P25 displaceable. On the carriage 80 are for supplying a the wire S forming wire D, a vertical bar preference 81 arranged with a force acting as a wire feeder feed clamp 82 and a laterally projecting adjusting rail 83.

The feed clamp 82 has two wedge-shaped, with the preference bar 81 fixedly connected preferred jaws 84, two cooperating with the preferred jaws 84, movable wedge-shaped clamping jaws 85 and the jaws 85 against the preferred jaws 84 pressing spring 86. The arranged on the base plate 76 backstop 77 is analog constructed to feed clamp 82 and has two wedge-shaped, with the base plate 76 fixed Locking jaws 87, two cooperating with the locking jaws 87, movable wedge-shaped clamping jaws 88 and a clamping jaws 88 against the locking jaws 87 pressing spring 89. At the projecting end of the adjusting rail 83, a vertical Vorstechbalken 90 is arranged, the like with the aid of not shown drive means, such as a working cylinder, adjusting spindle, according to the double arrow P26 adjustable and fixable on the adjusting rail 83. At Vorsteckbalken 90 at least one Vorstechnadel 91 is mounted such that it extends perpendicular to the adjusting rail 83 and perpendicular to the piercing bar 90 with its free, projecting end in the direction against the component B. The cross-sectional shape of the Vorstechnadel 91 is preferably round, wherein the diameter of the Vorstechnadel 91 is at least equal to the diameter of the insulator to be passed through the bar wire S, but preferably greater than the diameter of the web wire S. At its free end, the pilot needle 91 is provided with a wear-resistant, preferably hardened tip 92.

The described web wire feeding device 6 operates in the following manner: By the advancing movement of the carriage 80 in the direction of the component B facing direction of the double arrow P25 the Vorstechnadel 91 is moved against the component B. In this case, the tip 92 penetrates into the insulating body W and forms during the advancing movement a receiving channel C in the insulating body W. The advancing movement of the carriage 80 is terminated when the tip 92 has completely penetrated the insulating body W and on the opposite side of the insulating body W exited is. In order to facilitate the penetration of the insulating body W, the Vorstechnadel 91 or only the tip 92 of the same, for example by means of induction coil or similar to a soldering iron by means of a heating element can be preheated.

Simultaneously with the advancing movement of the pilot needle 91 in the direction of the component B facing the double arrow P25, the wire D is withdrawn as a result of the advancing movement of the carriage 80 by means of the feed clamp 82 from the supply spool 32, not shown, via a, a vertical and horizontal straightening 93 or93 'having Dressur 33 and according to the arrow P12 along a through the preferred jaws 84 and whose feed movement defined bullet line advanced. Due to the advancing movement of the carriage 80 and thus the feed clamp 82 to the component B through the jaws 85 are pressed in addition to the action of the spring 86 to the web wire S due to the wedge-shaped design of them receiving preferred jaws and take this with. The jaws 85 are provided to increase the frictional engagement with the web wire S on its side facing the web S side in addition with a toothing.

At the same time pushes the web wire S during its feed, the jaws 88 of the backstop 77 against the spring 89 of the backstop 77 and the wider end of the wedge-shaped opening of the locking jaws 87 out, so that the locking jaws 87 oppose the advancing movement of the bridge wire S virtually no resistance. The web S is passed through a aligned with the bullet line cutting nozzle 94 of the cutting device 79 by a formed in a previous work cycle with the help of the pilot needle 91 in the insulating body I receiving channel C. The advancing movement of the bar wire S is continued until the initial piece of the bar wire S protrudes just above the plane of the wire mesh mat M and thereby in a subsequent step with the corresponding wires L and Q of the wire mesh mat M can be welded.

The length of the feed path of Vorstechnadel 91 and the web wire S are exactly the same. After completion of the feed movement of the web wire S using a cutting blade 95 of the cutting device 79 is separated from the wire D. The carriage 80 returns to its original position, the Vorstechnadel 91 is pulled out of the receiving channel C and the jaws 85 of the feed clamp 82 release the wire D, while now the jaws 88 of the backstop 77 hold the wire D in its position and prevent it from being pushed back in the direction supply reel 32.

In the context of the invention, it is also possible to take an already cut, directed web wire S a supply magazine and introduce with the help of the web wire feeding device 6 along the insertion line in the preformed receiving channel C. In this case, the training device 33, the backstop 77 and the cutter 79 remain out of action.

The base plate 76 is pivotally mounted at the pivot point 96 corresponding to the double arrow P13, so that any angle between the web wires S and the pre-needle 91 on the one hand and the longitudinal wires L, L 'of the wire mesh mats M, M' on the other hand are adjustable.

In the manufacture of the components B, the bar wires S, S 'are supplied in most cases from the two opposite sides of the component B, so that a bar wire feeding device 6, 6' is arranged on each side of the component B to be produced. In FIG. 6, for the sake of clarity, only a second pre-piercing needle 97 and a further web wire S 'have been drawn. The Vorstechnadel 97 moves according to the double arrow P27, while the web wire S 'according to the Peil P12' is advanced. The movement of the Vorstechnadel 97 in the direction of the component B and the passage of the web wire S 'through the insulating body W take place simultaneously and together.

The Vorstechnadel 97 and the web wire S 'are shown in a snapshot of their corresponding feed movement, just before they reach their final position. The Vorstechnadel 97 forms from this side in the insulating body W receiving channels C 'for the ridge wires S'.

For simultaneous feeding of a plurality of webs S per work cycle are on feed bar 81 more feed terminals 82nd arranged with selectable intervals one above the other in the web wire planes ZZ, and arranged in the corresponding positions a plurality of associated backstops 77 and cutting devices 79 fixed to each other on the base plate 76. To form the corresponding receiving channels C, a plurality of preforming needles 91 are arranged one above the other on the precut bar 90 in the corresponding bar wire planes ZZ. Each pre-piercing needle 91 is located together with the bullet line of the associated feed clamp 82, the associated cutting nozzle 94 and the associated backstop 77 in the horizontal web wire plane ZZ (Fig. 7b). When introducing pre-stretched web wires in the receiving channel C each Vorstechnadel 91 together with the associated insertion also in the corresponding horizontal web wire plane ZZ. In order to adapt to different thicknesses of the insulating body W, all Vorstechnadeln 91 together by means of a drive device, not shown, such as an adjusting spindle, drive chain and the like displaced in the longitudinal direction and fixed in its working position by means of a clamping device, for example by means of a clamping screw in the piercing bar 90.

For simultaneously feeding a plurality of webs S 'per power stroke corresponding devices on the other side of the production channel 2 in the web wire planes Z-Z are arranged one above the other.

The tools for forming the receiving channel for the web wires S, S 'may be formed as solid plug or hollow needles or as a rotating drill, and have a wear-resistant, for example, hardened tip. The plug or hollow needles are preferably preheated in their tips to facilitate penetration of the insulating body W.

In the context of the invention, it is possible to form the Vorstechnadel in the form of a hollow needle and to attach them coaxially with the web wire S, S 'in the insertion line of the web wire S, S' at the feed clamp 82. The inner diameter of the Hollow needle is just so large that the bridge wire S, S 'can be pushed through it. By this movement, the hollow needle and the web wire S, S 'are simultaneously and coaxially advanced by the advancing movement of the feed clamp 82, wherein the hollow needle forms the receiving channel C simultaneously with the advance of the web wire S, S'. In this embodiment, the hollow needle with the aid of the feed clamp 82 must first be retracted to its original position before the introduced into the insulating body W web wire S, S 'can be separated from the wire supply D using the cutting device 70.

The trimming devices 8, which are shown only diagrammatically in FIG. 7a, have a cutting bar 98 pivotable in the direction of the double arrow P28, which runs parallel to the wire mesh mats M, M 'of the component B and carries a plurality of upper blades 99 arranged respectively in the region of each web wire plane Z-Z. In the illustrated embodiments, the wire mesh mats M, M 'of the component B are arranged standing upright, so that in Fig. 7a, the web wire plane Z-Z coincides with the plane and the cutting bar 98 extends vertically. The Besäumvorrichtung 8 also has a corresponding to the directions of the double arrow P29 pivotable cutter bar 100 which is parallel to the wire mesh mats M, M 'of the component B and a plurality, in the region of each web wire plane Z-Z arranged lower blade 101 carries.

Each upper blade 99 has, as shown in FIGS. 7a, 7b and 7c, two recesses 102 for each transverse wire Q of the wire mesh mat M, so that it becomes possible for the upper blades 99 to be in their working position between the longitudinal wires L without interference from the transverse wires to turn the wire mesh mat M. The dimensions and distances of the recesses 102 are selected according to the transverse wire pitch of the wire mesh mats M. Each upper knife 99 also has two catch noses 103 on, which are provided on its underside with a triangular guide and Zentrierausnehmung 104 for the longitudinal wires L.

Each lower blade 101 has two Abweisnasen 105, which prevent the pivoting of the lower blade 101 in the cutting position that the lower blade 101 in this case push under the longitudinal wires L of the wire mesh mats M and get tangled there. Between the two Abweisnasen 105 is the cutting edge 106 for separating the web wire protrusion E. The upper blade 99 and the lower blade 101 are made of hardened material, the flanks of the cutting edge 106 are additionally ground.

The trimming device 8 operates in the following manner: According to FIG. 7b, the upper knife 99 and the lower knife 101 are each in their initial position outside the component B. With the aid of correspondingly driven swivel devices, the cutting bar 98 pivots and thus also all the upper knives 99 from their in FIG 7b together in the corresponding direction of the double arrow P28 toward the component B toward a centering position shown in FIG. 7c. In this case, the catch noses 103 engage between the grid wires L1 in this way; Q of the wire mesh mat M, that the longitudinal wire L1, to which the bridgewire to be sawn S1 is welded, in the guide and Zentrierausnehmungen 104 of the catch noses 103 of the upper blade 99 is set. The guide and Zentrierausnehmungen 104 are designed such that both the longitudinal wire L1 is securely caught and guided when pivoting the upper blade 99 and the upper blade 99 forms an abutment for this by fixing the longitudinal wire L1. The pivoting of the upper blade 99 is not hindered by the transverse wires Q, since they find sufficient clearance in the recesses 102 of the upper blade 99 (FIG. 7). The lower blade 101 remains in its initial position for the time being.

With the help of correspondingly driven pivoting devices pivot in a following step, the cutter bar 100 and thus all lower blade 101 from their in Figs. 7b shown starting position together according to the direction of the component B direction of the double arrow P29 guided by the Abweisnasen 105 in a cutting position shown in Fig. 7c. In this case, the cutting edge 106 comes to the disconnected web wire projection E to the plant.

The cutting position shown in Fig. 7c, however, means no interruption of the movement sequence P29 of the cutter bar 100, but is merely an instantaneous representation of the movement sequence. The lower blade 101 continues to move in the direction of the double arrow P29 against the component B and separates the web wire projection E from. After separation of the web wire protrusion E, the separating beams 98 with all upper knives 99 and the knife bar 100 with all lower knives 101 pivot back into their starting positions. The now trimmed component B is then advanced horizontally in the production direction P1, so that further columns of untrimmed ridge wires are brought into the area of action of the trimming device 8.

The trimming device 8 'is constructed analogously to the trimming device 8 and in each case separates the other web wire protrusion E' synchronously with the trimming device 8.

The component B shown in axonometric view in FIG. 8 consists of an outer and an inner wire mesh mat M or M ', which are arranged parallel to each other at a predetermined distance. Each wire mesh mat M or M 'consists of a plurality of longitudinal wires L and L' and of a plurality of transverse wires Q and Q ', which intersect each other and are welded together at the crossing points. The mutual distance of the longitudinal wires L, L 'and the transverse wires Q, Q' to each other is selected according to the static requirements of the component B. The distances are preferably the same size, for example, selected in the range of 50 to 150 mm, so that the respective adjacent longitudinal and transverse wires form square mesh. In the context of the invention, the meshes of the wire mesh mats M, M 'can also be rectangular and, for example have short side lengths of 50 mm and long side lengths in the range of 75 to 100 mm.

The diameters of the longitudinal and transverse wires L, L 'and Q, Q' are also selectable according to the static requirements and are preferably in the range of 2 to 6 mm. The surface of the wires L, L '; Q, Q 'of the wire mesh mats M, M' may be smooth or ribbed in the invention.

The two wire mesh mats M, M 'are connected to one another by a plurality of webs S, S' to a dimensionally stable grid body A. The webs S, S 'are welded at their ends in each case with the wires of the two wire mesh mats M, M', wherein in the context of the invention, the web wires S, S 'either, as shown in Fig. 8, with the respective longitudinal wires L, L 'or with the cross wires Q, Q' are welded. The ridge wires S, S 'are alternately inclined in opposite directions, i. arranged in a lattice, whereby the grid body A is stiffened against shear stress.

The spacings of the webs S, S 'to each other and their distribution in the component B depend on the static requirement on the device and are for example along the longitudinal wires 200 mm and along the transverse wires 100 mm. The mutual distances of the webs S, S 'in the direction of the longitudinal wires L, L' and the transverse wires Q, Q 'are expediently a multiple of the mesh pitch. The diameter of the longitudinal wires L, L 'and the transverse wires Q, Q' is preferably in the range of 3 to 7 mm, wherein for components with thin longitudinal and transverse wires, the diameter of the web wires S, S 'is preferably selected to be larger than the diameter of Longitudinal and transverse wires.

The spatial grid body A formed from the two wire mesh mats M, M 'and the web wires S, S' must not only be dimensionally stable, but also fulfill the function of a spatial reinforcement element in its preferred use as a wall and / or ceiling element, ie and absorb pressure forces. Therefore, both the longitudinal and transverse wires with each other, as usual with reinforcing mats, as well as the bridge wires S, S 'with the wires L, L'; Q, Q 'of the wire mesh mats M, M' welded while maintaining a minimum strength of the weld knots. In order to fulfill the function of a spatial reinforcement element, the wires L, L '; Q, Q 'of the wire mesh mats M, M' and the web wires S, S 'consist of suitable materials and have corresponding mechanical strength values, so that they can be used as reinforcement wires for the wire mesh mats M, M' to be used as reinforcing mesh mats or as the two wire mesh mats M, M 'connecting reinforcing wires are used.

In the space between the wire mesh mats M, M 'an insulating body W is arranged at a predetermined distance from the wire mesh mats, whose top surfaces parallel to the wire mesh mats S, S' extend. The insulating body W is used for thermal insulation and sound insulation and consists for example of foamed plastics, such as polystyrene or polyurethane foam, rubber and rubber-based foams, lightweight concrete, such as autoclave or aerated concrete, porous plastics, porous rubber and rubber-based materials, pressed Schlakke, plasterboard Cement-bonded press plates consisting of wood chips, jute, hemp and sisal fibers, rice husks, straw waste, mineral and glass wool, corrugated board, pressed waste paper, bonded brick chippings, and melted recyclable plastic waste. The insulator W can in the context of the invention also consist of bioplastics, for example, algae foam, which is made from foamed algae or algae pulp.

The insulating body W can be provided with predrilled holes for receiving the web wires S, S '. The insulating body W can also be provided on one or both sides with a serving as a vapor barrier plastic or aluminum layer. The position of the insulating body W in the component B is determined by the inclined webs S, S ', which penetrate the insulating body W.

The thickness of the insulating body W is arbitrary and is for example in the range of 20 to 200 mm. The distances of the insulating body W to the wire mesh mats M, M 'are also freely selectable and are for example in the range of 10 to 30 mm. The component B can be produced in any desired length and width, with a minimum length of 100 cm and standard widths of 60 cm, 100 cm, 110 cm and 120 cm having proved to be advantageous on the basis of the manufacturing method.
