Wire mesh mats M, M 'in order to ensure a safe further promotion of the wire mesh mats M, M' by the wire mesh mat conveyor 16.

The insulating 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 separating the insulating body W from the insulating material web K. The insulating material feeding device 3 has a Slide-in device 19, which the insulating for the formation of the insulating W of the component B certain insulating I according to the direction of arrow P4 of the production line XX of the system feeds laterally. The insertion device 19 essentially consists of two working cylinders 20 whose piston rods are moved in accordance with the double arrow P5 and are provided with a pressure plate 21 at their end. 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 Pl 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 the position of the insulating plates I in the production line XX is determined precisely. 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 in accordance with the double arrow P6 and provided with a pressure plate adapted to the end face of the insulating plate I. With the help of the feed device 25 located on the conveyor belt 22 insulating plate I 'is additionally advanced according to the arrow Pl 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 is a connection 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 perpendicular to the production line X-X and parallel to the production line X-X corresponding to the directions of the double arrow, in accordance with the directions of the double arrow P7

P8 movable. 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 produced, for example, by heat welding with the aid of a heating device. formed connecting device 26 with the insulating material K connected. 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 web K and the insulating plate I 'are softened. The heating plate is then rapidly pulled out of the space 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' advanced slightly with the aid of the feed device 25 in accordance with the production direction P6 in order to move the heated end faces toward one another press and thus the insulating plate I 'to be welded to the insulating material K and thus form and locks to connect. 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 Pl, 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 The opposite direction of the double arrow P8 moved back into the Ausgangsläge.

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 adhesive must be used to bond the material of the insulation plates I, I 'and have a tuned to the production speed drying time to ensure a secure connection of the insulating plate I' with the insulating material web K. The adhesive device is for spraying the adhesive on the end face F of the insulating plate 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 first inserted laterally into the production line XX with the aid of the insertion device 19 in accordance with the direction of the arrow P4 and deposited on the conveyor belt 22. Subsequently, the insulating plate I 'is advanced by means of the feed device 25 in accordance with the production direction Pl to press the adhesive face of the insulating plate I' against the end face of the insulating material K and thus the insulating plate I 'with the insulating material web K form - and to connect frictionally.

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 of the insulating panels I, I 'to be joined as well as their fixing - li ¬

the connection with each other is guaranteed. The connection 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. Within the context of the invention, the end faces of the insulating plates I, I 'adjacent to form the insulating material web K can also be provided with other clamping connection elements which cooperate positively and non-positively and which, for example, are dovetail-shaped.

It is understood that the exemplary embodiments illustrated may be modified variously, in particular with regard to the configuration and design of the devices for connecting the insulating plates I, I 'to form an endless insulating material web K within the scope of the general inventive concept. When using appropriate adhesives, both the end face F of the insulating plate I, I 'and the end-side end face of the insulating material web 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 during the production of the insulating panels I, I 'and is expediently protected by a peelable film.

Adjoining the conveyor belt 22 is a conveyor device extending over the entire production line X-X, for example a conveyor chain 27 which can be driven in accordance with the production direction P1 and moves the insulating material web K and the insulating bodies W in the production line X-X in a cyclic manner 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 Pl during cutting and returned to the initial position after the cut, these movements being carried out 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, a cutting wire movable transversely to the insulating material web K and heatable by means of a heating transformer can be used as the insulating material web cutting device.

Since the cutting device 28 is also conveyed step by step in the cycle of the entire production plant according to the production direction Pl when cutting the Isoliermaterialbahn K by the conveyor chain 22, the Schneidvorrich- device 28 is also gradually moved during the cutting in accordance with the corresponding arrow direction of the double arrow P10 and after quitting of the cut in the corresponding opposite direction of the double arrow P10 moved back to the starting position. The conveyor chain 27 conveys the insulating bodies W separated from the insulating material web K according to the product. tion direction Pl in the subsequent processing devices of the system.

Since the conveyor chain 27 must not extend into the trajectories of the connecting device 26 and the cutting device 28, the Isoliermaterialbahn K is supported in this area of at least two support members 31 by means of a working cylinder corresponding to the double arrow Pll from the movement path of the connecting device 26 and the cutting device 28 can be moved. In the context of the invention, it is also possible to provide additional, acting on the insulating material K clamping elements, which additionally fixes them when connecting the insulating plate I 'with the already formed Isoliermaterialbahn K.

On both sides of the production channel 2, the guide devices 15, 15 'are respectively followed by a bar wire feeding device 6, 6', with which several wires D, D 'are simultaneously fed from wire supply spools 32, 32' from both sides of the production channel 2 in steps Arrow direction P12, P12 ^■ withdrawn, straightened by means of a dressing device 33, introduced in the horizontal direction into the space between the two wire mesh mats M, M ', pushed through the insulating body W, like a nail, and separated from the wire supply. The piercing of the insulating body W is substantially facilitated by heating the tips of the web wires S, S ', wherein the heating takes place, for example, by an inductively operating heating device.

In the context of the invention, it is also possible to arrange all bar-wire feeders 6, 6 'on one side of the production channel 2 in the production direction Pl in succession.

In the context of the invention, it is possible to supply already pre-stretched webs S, S 'in vertically extending rows in selectable angles to the wire mesh mats M, M' the production channel 2 side. Also in this case can Preheat the tips of the bridge wires using appropriate heaters.

Insulating body W is penetrated by a plurality of rows of a plurality of straight ribbed wires S, S 'arranged one above the other at a mutual distance in the vertical direction. 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 secure welding with the corresponding longitudinal wires L, L ^{1 of} the wire mesh mats M, M '. As the embodiment of the component B shown in FIG. 8 shows, the web wires S, S 'are each welded to the longitudinal wires L, L', wherein, as shown in FIG. 7b, all the web wires Sl, Sl 'along a wire pair Ll, Ll 'lie in one with the longitudinal wire pair Ll, Ll' common web wire plane ZZ and the sense of direction of the web wires Sl, Sl 'zigzag changes in the plane ZZ, so that a truss-like arrangement of the web wires Sl, Sl' arises. The respective angles of the webs Sl, Sl 'to the longitudinal wires Ll, Ll' 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) of the two webs S and S 'to the wire mesh mats M, M' in terms of value equal but are chosen with different signs in order to achieve the fachwerkarti- ge stiffening of the component B.

The material and the construction of the insulating body W must be such that the insulating body W, the web wires S in which subsequent, take place in the direction of production Pl further 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 produce the insulating body W of the component B from such hard materials that it can not be penetrated by the webs S, S 'without deformation, for example hard plastics, such as polyurethane, lightweight concrete, gypsum plasterboard or cementitious pressboard containing waste plastics, wood chips or wood shavings, mineral or vegetable fibrous matter containing expanded or foamable polystyrene, in which case each piercing wire feeding device 6, 6 'will each have a piercing device 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 two wire mesh mats M, M 'with the aid of the second feed element pair 18, 18' of the Drahtgittermatten- conveyor 16 stepwise and synchronously with the means of the conveyor chains 27, 27 'advanced insulating W together with the land wires S, S' the downstream web-wire welding 7th , 7 ', in which the webs S, S' are each welded at one end to the longitudinal wires L, L 'of the wire mesh mats M, M' by means of pairs of welding guns pivotable into the web wire planes ZZ. The welding guns are designed as pairwise cooperating, two-armed, pivotable lower and upper welding gun levers, whose wire mesh mats M; M 'facing ends pivotable in the web wire planes ZZ at least one welding electrode for the purpose of welding at least one bar wire S; S 'with a longitudinal wire L, L' of the wire mesh mat M; M 'have.

The bar-wire welding devices 7, 7 'are offset from one another on the outside of the two wire mesh mats M, M' and are displaceable in the longitudinal direction and transversely to the production channel 2. In the context of the invention, two or more web welding devices 7, 7 'per side surface, as seen in the feed direction Pl of the wire mesh mats M, M', can be arranged one behind the other. The now dimensionally stable component B is further promoted by a downstream component conveyor device 35, which has substantially two pairs of mutually opposite to both sides of the production channel 2 conveying elements 36, 36 'and 37, 37'. The protruding over the wire mesh mats M, M 'protrusions of the web wires S, S' pose a significant risk of injury in the handling of the component B, hinder the stacking of the components for transport and must therefore be separated so that the ridge wires S, S 'possible flush with the longitudinal wires L, L '. With the aid of the first pair of spring elements 36, 36 ', the component B is fed to the downstream, on opposite sides of the production channel 2 staggered arranged Besäumvorrichtungen 8, 8', which over the respective longitudinal wires L, L 'of the wire mesh mats M, M' laterally projecting web wire - Cut off projections E, E 'flush with longitudinal wires L, L'. In order to increase the production speed of the system, moreover, in the context of the invention, on each side face of the component B to be trimmed, a plurality of trimming devices 8, 8 'can be arranged one behind the other in the direction of production P1.

The finished trimmed component B is conveyed out of the production channel 2 with the aid of the second pair of conveyor elements 37, 37 'of the component conveyor 35, and the component Pass elements cross conveyor 9 for removal and stacking of several components B.

The distance between the second feed element pair 18, 18 'of the wire mesh mat conveyor 16 and the first pair of conveyor elements 36, 36' of the component conveyor 35 and the distance between the conveyor element pairs 36, 36 'and 37, 37' must always be smaller than the smallest Length of the wire mesh mats M, M 'used to make the component B, in order to ensure safe Weiterfδrderung the wire mesh mats M, M' between the wire mesh mats conveyor 16 and the component conveyor device 35 and through them.

For the continuous production of the components B, it is absolutely necessary that the two wire mesh webs G, G ', the wire mesh mats M, M' and the insulating material web K or the individual insulating panels I the individual processing stations 5, 5 '; 6, 6 '; 7, 7 '; 8, 8 '; 9 safe and trouble-free supply. To ensure this, the wire mesh feed rollers 10, 10 ', the feed element pairs 17, 17'; 18, 18 'of the wire mesh mat conveying device 16, the conveying element pairs 36, 36'; 37, 37 'of the component conveying device 35 and the conveyor chains 27, 27' driven by a central main feed drive 38, wherein all elements 17, 17 '; 18, 18 '; 36, 36 '; 37, 37 'and the feed rollers 10, 10' by means of articulated drive shafts 39, 39 '(Fig. 2) are interconnected. The feed steps take place cyclically, because the insertion of the web wires S, S ', the welding of the web wires S, S' with the wires of the wire mesh mat M, M 'and the trimming of the web wire projections E, E' respectively at standstill of the wire mesh mats M, M ' , the insulator W or of the component B take place. Here, the length of the feed steps corresponding to the cross-wire pitch or an integral multiple of the cross-wire pitch can be selected.

By broadening the production channel 2 and the guiding devices 15, 15 'as well as corresponding, individually or jointly sam lateral adjustment of the feed elements 17, 17 '; 18, 18 ', the conveying elements 36, 36'; 37, 37 'and the elements of the processing stations 6, 6'; 7, 7 '; 8, 8 'transverse to the production line XX components B can be made with different, predetermined width.

With the aid of the component cross conveyor 9, the finished component B is conveyed out laterally from the production line X-X. The components B is first supplied from a provided with a correspondingly shaped gripper feed dog 40 along the production line X-X a transverse conveyor 41. The feed dog 40 may for example consist of a working cylinder whose piston rod is movable in accordance with the double arrow P14. The transverse conveyor 41 consists for example of two working cylinders whose piston rods are movable in accordance with the double arrow P16 and each provided with a push-off plate 42. The cross conveyor 41 pushes the finished components B according to the direction of arrow P15 from the production line X-X in a tilting device 43 shown only schematically, which has a plurality of, corresponding to the directions of the double arrow P17 pivotable uprights 44. The upright produced in the production plant components B are brought by means of the tilting device 43 in a horizontal position and stored on a stack of components T.

The plant shown in FIG. 2 consists of an insulating material feed device 3, a wire mesh feed device 4, and a wire mesh feed device 45, as seen in the production direction Pl.

The wire mesh mat M is formed according to the embodiment of FIG. 1. The supply of already prefabricated wire mesh M 'with the help of Drahtgittermatten- supplying device 45 in the following manner: From a mat stack 46 by means of a conveyor 47, which is pivotable according to the double arrow P18, successively removed wire mesh mats M' and stored in a receiving rail 48 , With the aid of a push-in device 49, the wire mesh mats M 'according to the direction of arrow P19 successively via a directional device 50 of a corresponding to the double arrow P20 drivable feed device 51, for example, a feed roller supplied. The insertion device 49 consists for example of a working cylinder whose piston rod is movable according to the double arrow P21 and which is provided with a gripper 52 for detecting the wire mesh mat M '. The wire mesh mat straightening device 50 has an inlet guide 53 for the wire mesh mat M ', a plurality of dressage rollers 54 and eccentric rollers 55 arranged offset in two rows. The feed roller 51 pushes the wire mesh mats M 'successively in the production line X-X, where they at a distance and parallel to the insulating material K and together with this by means of the conveyor element pairs 17 17'; 18, 18 'in the direction of production Pl stepwise along the production line XX the downstream processing devices 6, 6'; 7, 7 'and 8, 8' are supplied.

In the context of the invention, it is possible, instead of the wire mesh web G, to provide a second mat stack with prefabricated wire mesh mats M and to supply the mats with the wire mesh feed apparatus 4.

The Fδrdervorrichtung shown schematically in Fig. 3 for the wire mesh mat M, M 'and the insulating body W has the Hauptschubantrieb 38 according to the direction of arrow P22 driven conveyor chain 27, which defines the conveying path of the insulating body W within the production channel 2. The conveyor chain 27 carries a plurality of carrier carrier 56, which are each provided with a driver 57. The drivers 57 are angular, hook-shaped or thorn-like design to produce a secure connection with the underside of the insulating body W and thus to avoid any slippage between this and the driver carriers 56 during advancement of the insulating body W.

When the insulating bodies W are reliably fed in, the conveying device has a further upper conveyor chain 27 'with corresponding chenden Mitnehmerträgern 56 'and drivers 57', which engage at the top of the insulating body W.

The advancing elements 17, 18 of the wire mesh mat conveying device 16 shown only schematically in FIG. 3 have a shaft 58 inclined to the vertical, which is driven by a bevel gear 60 via a coupling 59 and is mounted in an abutment 61. The angle gear 60 is driven via the drive shaft 39 from the main feed drive 38. Each shaft 58 is provided with a plurality of spaced-apart transport discs 62 which are rotatable for adjustment on the shaft 58 and, after adjustment by means of a clamping element 63, are fixedly connected to the shaft 58.

The transport disks 62 have, as shown in Fig. 4a, a plurality of regularly distributed on the circumference lattice engagement recesses 64 with selectable depth, so that flattened teeth 65 arise. The number of lattice engagement recesses 64 is selected in accordance with 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 ¹ 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 Drahtgit- 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 conveying device 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 essentially the same elements as the feed elements 17, 18 of the wire mesh mat conveying device 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 produce with the system according to the invention components B, in which the wire mesh mats M, M 'different structure, ie, different longitudinal wire pitches and / or transverse wire pitches and different diameters of the longitudinal wires and / or transverse wires. However, the various cross-wire divisions must be integer

Multiples correspond and may for example be 50, 100 or 150 mm. Another limitation is that it must be ensured that the webs S, S ¹ can be positioned so that they can be securely welded to the longitudinal wires of the two wire mesh mats M, M 'despite these different wire divisions and wire diameter.

It is possible with the system according to the invention to produce components B in which one and / or both wire mesh mats M, M 'project beyond the insulating body W on one or both sides running parallel to the production direction Pl. In order to achieve this, either the drivers 57 are raised or extended in such a way, or the conveying path of the conveyor chain 27 is raised such that the lower side surface of the insulating body W running parallel to the production direction Pl is raised correspondingly, 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 producing components B, in which the insulating bodies W project beyond the two wire mesh mats M, M 'on one or both sides or sides running parallel to the production direction Pl, the conveying path of the lower conveyor chain 27 is lowered and, if appropriate, the conveying path of the conveyor belt raised upper conveyor chain 27 'such that the lower and possibly the upper, parallel to the production direction Pl running 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 ' surmounted on one or 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 without significant gaps follow each other.

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 production direction Pl. 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 insulating material web K, it must be NEN of the insulating body W a distance corresponding to this part of 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 producing components B, in which the insulating bodies W project beyond the two wire mesh mats M, M 'on one or both sides extending perpendicularly to the production direction P 1, the wire mesh mats M, M' are advanced in the production channel 2 at a predetermined distance. In order to produce this selectable distance between the wire mesh mats M, M 'of successive components B, a part piece corresponding to this distance is cut out of the endless wire mesh webs G, G' by the wire mesh mats cutting devices 5, 5 'during production of the wire mesh mats M, M'. The size of the distance is limited in that it must be ensured 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 ensure a slip-free feed of the wire mesh mats M, M 'of successive components B.

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. To cut through the wire mesh web G, the cutting bar 68 carries a counter knife 70. The knife bar 69 carries a cutting knife 71, which cooperates with the opposing counter knife 70 during the cutting 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. In the context of the invention, it is possible to use a plurality of counter and cutting blades instead of a counter knife and a cutting blade, either individually or in groups to sever each longitudinal wire L of the wire mesh track. 5b shows a further embodiment of a wire mesh mat cutting device 5, 5 ', which makes it possible to cut a selectable section out of the wire mesh web G, the length of which in the feed direction P3 is preferably the distance between adjacent transverse wires, the so-called transverse wire pitch. or an integer multiple of the transverse wire pitch, wherein 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 mesh web 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 on the length of ge of 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 piece and piece, 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 cutting 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 return lock 77, a guide rail 78 running 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. To feed a wire D forming the bar wire S, a vertical preferred bar 81 with a feed clamp 82 acting as a wire feed device and a laterally projecting adjusting bar 83 are arranged on the carriage 80.

The feed clamp 82 has two wedge-shaped, with the preferential beam 81 firmly 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 77th is constructed analogously to the feed clamp 82 and has two wedge-shaped, with the base plate 76 fixed Bound locking jaws 87, two interacting with the locking jaws 87, movable wedge-shaped clamping jaws 88 and the 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 of 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 a horizontal straightening 93 and93 'having Dressurein- direction 33 and corresponding to the arrow P12 along a through the preferred jaws 84 and their feed movement defined bullet line advanced. Due to the advancing movement of the carriage 80 and thus the feed clamp 82 toward the component B, the clamping jaws 85 are pressed against the web wire S in addition to the action of the spring 86 due to the wedge-shaped design of the preferred jaws 84 receiving them and take it with them. 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, so that the locking jaws 87 of the advancing movement of the bridge wire S virtually no NEN resistance -gegengegensetzen , 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 starting piece projects the bar wire S just above the plane of the wire mesh mat M and thereby can be welded to the corresponding wires L or Q of the wire mesh mat M in a subsequent working step. The length of the feed path of Vorstechnadel 91 and the

Stegdrahtes 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 bridge wire S 'is advanced according to the Peil P12'. 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 pre-piercing needle 97 and the bar wire S 'are shown in a moment recording 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 land wires S '.

For simultaneous feeding of a plurality of webs S per working cycle, several feed terminals 82 are produced on the preferential bar 81 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 Auf ahmekanäle C Vorstechbalken 90 a plurality Vorstechnadeln 91 are arranged in the corresponding web wire planes ZZ one above the other. Each Vorstechnadel 91 is located together with the bullet line of the associated feed clamp 82, the associated cutting nozzle 94 and the associated return lock 77 in the horizontal web wire plane ZZ (Fig. 7b). When inserting pre-stretched webs wires in the receiving channel C each Vorstechnadel 91 together with the associated insertion also in the corresponding horizontal web wire plane ZZ. For the purpose of adaptation to different thicknesses of the insulating body W, all preforming needles 91 can be displaced in the longitudinal direction together by means of a drive device, for example an adjusting spindle, drive chain and the like, and fixed in their working position by means of a clamping device, for example by means of a clamping screw in the piercing bar 90 become.

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-in or hollow needles are preferably preheated in their tips in order to facilitate piercing 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 these coaxial with the

Bridge wire S, S 'in the insertion line of the bridge wire S, S' to the feed clamp 82 to attach. The inner diameter of the Hollow needle is just so large that the bridge wire S, S 'can be pushed through it. As a result of this arrangement, the advancing movement of the feed clamp 82 advances the hollow needle and the web wire S, S 'simultaneously and coaxially, the hollow needle forming the receiving channel C simultaneously with the advancement of the bar 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 exemplary 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 of the drawing and the cutting bar 98 extends vertically. The trimming device 8 also has a knife bar 100 which can be pivoted in accordance with the directions of the double arrow P29 and which runs parallel to the wire mesh mats M, M 'of the component B and carries a plurality of bottom knives 101 arranged in the region of each metal wire plane Z-Z.

Each upper blade 99, as shown in FIGS. 7a, 7b and 7c, has two recesses 102 for each transverse wire Q of the wire mesh mat M, so that it is possible to move the upper blades 99 into their working position between the two without interfering with the transverse wires Swing longitudinal wires L of 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 towards the component B in a centering position shown in FIG. 7c. In this case, the catch lugs 103 engage between the grid wires Ll; Q of the wire mesh mat M, that the longitudinal wire Ll, to which the bridgewire to be sawn Sa is welded, in the guide and Zentrierausnehmungen 104 of the catch noses 103 of the upper blade 99 is set. The guiding and centering recesses 104 are designed in such a way that both the longitudinal wire L1 is securely caught and guided during pivoting of the upper blades 99, and the upper blade 99 forms an abutment for the latter 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 aid of correspondingly driven pivoting devices, in a following working step, the knife banks 100 and thus all lower knives 101 pivot out of their position as shown in FIG. 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. Here, the cutting edge 106 comes to rest on the web wire projection E to be separated.

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 bridgewire supernatant E, the divider beams 98 with all upper knives 99 and the knife bar 100 with all lower knives 101 return to their initial positions. The now trimmed component B is then advanced horizontally in the production direction Pl, 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 synchronously with the trimming device

8 the other web wire projection E 'from.

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 short Seitenl lengths of 50 mm and have 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 ^{1 are} welded. The web wires S, S 'are alternately inclined in opposite directions, ie, they are 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 web wires S, S 'in the direction of the longitudinal wires L, L' and the transverse wires Q, Q ¹ 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 chosen to be greater than the diameter of the 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. Therefore, both the longitudinal and transverse wires are one behind the other, as is usual with reinforcing mats, as well as the bar 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 support 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. Insulating body W serves 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 gas concrete, porous plastics, rubber and rubber-based porous materials, pressed slag, gypsum plaster boards, cementitious press boards 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 webs 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.
