Abstract

The invention relates to a method and device for continuously producing components (B), whereby two wire mesh mats (M, M') are placed in a parallel position at a distance from one another that corresponds to the desired thickness of the component (B). In order to form an insulating body (W) of the component, a plate (I, I1, I1', I2, I2') made of a heat-insulating material is inserted into the space between the parallel wire mesh mats while being situated at a distance from each wire mesh mat. In addition, a number of connecting wires (S, S') are, at the same time, inserted into the space between the wire mesh mats whereby passing through at least one of the two wire mesh mats. These connecting wires start from at least one side while running in a diagonal manner that alternates in opposite directions and in planes extending perpendicular to the planes of the wire mesh mats. The free ends of the connecting wires are pushed through the insulating body, whereby each connecting wire comes to rest near a wire (L, L', L1, L1'; Q, Q', Q1, Q1') of both wire mesh mats, and the connecting wires are welded to these wires. The ends of the connecting wires projecting beyond the wires are then cut off.

Further features and advantages of the invention are explained in more detail below using exemplary embodiments with reference to the drawings. Show it:

The system according to the invention shown in Fig. 1 is used to manufacture a component B consisting of two parallel, flat wire mesh mats M, M 'of longitudinal and transverse wires L, L' and Q, Q ', welded together and welded to each other at the crossing points, from the two Wire mesh mats M, M 'at a predetermined mutual spacing straight web wires S, S', which are welded at each end to a wire of each of the two wire mesh mats M, M ', and from one between the wire mesh mats M, M' and with predetermined distance from these arranged, at least partially dimensionally stable insulating body W, for example an insulating plate I made of plastic.

The system has a base frame 1, on which a horizontal production channel 2, which is only indicated schematically, is preferably arranged in the center. Two upright wire mesh webs G and G 'are drawn off from two supply spools 3, 3' in accordance with the arrows Pl and Pl ', the mutual distances between the longitudinal wires L, L ¹ and the cross wires Q, Q' of each wire mesh web G, G 'to each other, ie the so-called line wire and cross wire divisions, as well as the width of each wire mesh web G, G' can be freely selected within certain ranges.

Via a wire mesh web guide 4, 4 ', each wire mesh web G, G' enters a straightening device 5, 5 ', each consisting of a plurality of staggered rollers 6, 6', which straighten each wire mesh web G, G '. Each straightening device 5, 5 'has on its inlet side a wire mesh feed device 7, 7', each consisting of a driver roller 8, 8 'and a drive roller 9, 9' interacting with the driver roller 8, 8 ', each Drive roller 9, 9 'by swiveling according to the double arrow P2, P2' either in or out of engagement with the driver roller 8, 8 ' can be brought. The wire mesh web feed devices 7, 7 'have the task of feeding the wire mesh webs G, G' for further processing of downstream wire mesh web insertion devices 10, 10 'in the direction of the arrows Pl, Pl', or after the end of production, no longer required pieces of the To promote wire mesh webs against the direction of the arrows Pl, Pl 'from the straightening device 5, 5'.

According to the double arrow P3, P3 ', each wire mesh insert device 10, 10' can be pivoted between a working position in which it is in engagement with the wire mesh web G, G 'to be inserted, and a rest position in which it is disengaged from the wire mesh web G , G 'stepwise wire mesh mat shears 11, 11' fed, each essentially having a cutting bar 12, 12 'and a cutter bar 13, 13' and severing wire mesh mats M, M 'of predetermined length from the endless wire mesh webs G, G'.

In the example shown, the wire mesh mat scissors 11, 11 'work in such a way that a cut is to be made and thus continuously separate wire mesh mats M, M' from the wire mesh webs G, G '. Within the scope of the invention, however, it is also possible to design and control the wire mesh mat shears 11, 11 'in such a way that they carry out a trimming cut on the longitudinal wires L, L' and in one or two cutting operations from the wire mesh webs G, G 'a selectable section cut out, the length of which in the feed direction preferably corresponds to the cross wire pitch or an integer multiple of the cross wire pitch.

By slightly curved, directed wire mesh mats M, M ¹ only elastically deforming and tangentially opening in opposite longitudinal sides of the production channel 2 guiding devices 14, 14 ', which consist for example of several arched strips arranged one above the other and by means of brackets 15, 15' and brackets 16, 16 'are attached to the base frame 1, the wire mesh mats M, M' are thus inserted into the production channel 2 passed that they get there in a parallel position to each other, with a mutual distance which corresponds to the desired thickness of the component B to be produced. In the production channel 2, the two wire mesh mats M, M 'are reliably guided over their entire width with the aid of only schematically indicated spacer elements 17, 17', which consist, for example, of spacer plates and a plurality of spacer guides arranged one above the other in the vertical direction, and always precisely defined in this Kept clear. With the aid of a wire mesh mat conveying device 18, which essentially has two pairs of feed elements 19, 19 'and 20, 20' arranged opposite each other and arranged on both sides of the production channel 2, the two wire mesh mats M, M 'are gradually moved into the guide devices 14, 14 'and conveyed along the production channel 2 in the production direction P4 to the downstream processing stations. The first pair of feed elements 19, 19 'is arranged in the parallel outlet area of the guide devices 14, 14'. The distance of the first pair of feed elements 19, 19 'from the wire mesh mat shears 11, 11' and the distance between the two pairs of feed elements 19, 19 'and 20, 20' from each other must be less than the smallest length of the wire mesh mats M, M intended for producing the component B. ¹ in order to ensure safe further conveyance of the wire mesh mats M, M 'by the wire mesh mat conveying device 18.

Individual insulating plates I are fed from a feeder device 21 in the direction of the arrow P5 to a guide device 22 which forms the inlet side of the production channel 2 and is fastened to the base frame 1 by means of a fastening plate 23. The guide device 22 is designed in such a way that the insulating plate I is reliably guided both in the vertical direction and in its position relative to the two wire mesh mats M, M 'and at a predetermined distance therefrom. The length and width of the insulating plate I preferably corresponds to the length or the width of the wire mesh mats M, M '.

In the inlet area of the guide device 22, the insulating plate I is grasped by an insulating body conveyor device 24 that extends over the entire length of the production channel 2 and is fed step by step synchronously with the wire mesh mats M, M 'to the downstream processing stations of the production system.

Within the scope of the invention it is possible to supply the feeder device 21 with an insulating material web K instead of the individual pre-cut insulating plates I and to separate insulating bodies W of predetermined length from the insulating material web K with the aid of an insulating material cutting device 25 arranged in the outlet area of the guide device 22. Corresponding exemplary embodiments are described in more detail in FIGS. 4 to 6.

On both sides of the production channel 2, a guidewire feed and cutting device 26, 26 'is connected downstream of the guiding devices 14, 14', with which a plurality of wires D, D 'are stepped from wire supply spools 27, 27' simultaneously from both sides of the production channel 2 in accordance with the direction of the arrow P6, P6 'removed, straightened by means of a dressing device 28, 28', inserted in the horizontal direction into the space between the two wire mesh mats M, M ', pushed through the insulating body W, as if by a nail, and separated from the wire supply , Puncturing the insulating body W is made considerably easier by heating the tips of the land wires S, S ', the heating being carried out, for example, by an inductively operating heating device.

Within the scope of the invention, it is possible to arrange all the bridge wire feed and cutting devices 26, 26 'one behind the other on one side of the production channel 2 in the production direction. Within the scope of the invention, it is possible to feed web wires S, S 'which have already been cut to length in vertically running rows Rl or R2 at selectable angles to the wire mesh mats M, M' to the side of the production channel 2. In this case too, the tips of the bridge wires can be preheated with the aid of appropriate heating devices.

The insulating body W is penetrated by a plurality of rows Rl and R2 each of a plurality of straight web wires S, S 'arranged one above the other in the vertical direction at a mutual spacing. The web wires S, S 'lie with their two ends slightly laterally on the corresponding longitudinal wires L, L' of the two wire mesh mats M, M 'in order to securely weld them to the corresponding longitudinal wires L, L' of the wire mesh mats M, M ' guarantee. In the illustrated embodiment of the component, which corresponds to the exemplary embodiment in FIG. 10, the web wires S, S 'run horizontally obliquely in the same direction within a vertical row R1 or R2 to the wire mesh mats M, M'. In adjacent rows Rl; R2, the bridge wires S, S 'are inclined in opposite directions. Seen in the horizontal direction, the web wires S, S 'in the form of horizontal lines H run obliquely between opposite longitudinal wires L and L' of the wire mesh mats M and M '. The respective angles of the bridge wires S, S 'to the longitudinal wires L, L' can be selected, the sense of direction of the bridge wires S, S 'changing within a row Z, so that a framework-like, zigzag arrangement of the bridge wires S, S' within a line H arises. A plurality of parallel, horizontal rows H of land wires S, S 'are therefore arranged one above the other in the vertical direction in the insulating body W, ie the land wires S, S ¹ form a matrix-like structure in the insulating body W and thus also in the component B to be produced, with the component B standing upright horizontal rows H and vertical rows R1, R2.

The weft angle at which the web wires S, S 'into the space between the two wire mesh mats M, M' are introduced, can be adjusted by pivoting the bridge wire feed and cutting device 26, 26 'according to the double arrows P7, P7'. The material and the structure of the insulating bodies W must be such that the insulating bodies W immovably fix the web wires S in their position within the insulating bodies W during the subsequent transport in the direction of production P4. The number, the weft angle and the mutual, vertical distances of the bridge wires S arranged one above the other in the vertical direction in a row Rl or R2, and the horizontal distance of the bridge wire rows are selected in accordance with the structural requirements for the component B.

In some cases, it may be necessary to manufacture the insulating body W of the component B from such hard materials that it cannot be penetrated by the bridge wires S, S 'without deforming it. For example, hard plastics such as polyurethane, expanded concrete or foamable polystyrene as a lightweight aggregate, lightweight concrete, gypsum plasterboard or cement-bonded press panels that contain plastic waste, wood chips or wood chips, mineral or vegetable, fibrous substances can be used. In these cases, each ridge wire feeding and cutting device 26, 26 'is preceded by a piercing device 29, 29' shown schematically in FIG. 1. Each pre-lancing device 29, 29 'has a plurality of tools arranged one above the other in the vertical direction, which are used to form a channel in the insulating body W for receiving a web wire S, S' and which are arranged on a common, pivotable stand. Here, the stands of the piercing devices 29, 29 'are firmly coupled to the associated bridge wire feed and cutting device 26, 26', and can be moved together with them in the direction of the insulating body W of the component B and away from it, and together with this correspondingly Double arrow P7, P7 'pivotable. Within the scope of the invention it is possible to design the piercing devices 29, 29 'in accordance with the device described in EP-B-398465. Here, the feed movement of the piercing devices 29, 29 'for shaping the receiving channel for the bridge wires S, S' takes place independently of the feed movement of the bridge wire feed and cutting devices 26, 26 '. Only the pivoting movement of each stand of the piercing devices 29, 29 'for changing the shot angle of the bridge wires S, S' takes place synchronously with the pivoting movement of the respectively associated bridge wire feed and cutting device 26, 26 'according to the double arrows P7, P7'.

The tools for shaping the receiving channel for the web wires S, S 'can be designed as solid pins or hollow needles or as rotating drills, and have a wear-resistant, for example hardened tip. The pins or hollow needles can preferably be preheated in their tips in order to facilitate penetration of the insulating body W.

With the aid of the second pair of feed elements 20, 20 'of the wire mesh mat conveying device 18, the two wire mesh mats M, M' are gradually and synchronously with the insulating body W advanced by means of the insulating body conveying device 24 together with the land wire welding devices 30, 30 connected downstream of the land wires S, S ''supplied, in which the web wires S, S' are welded at one end with the aid of welding tongs 31, 31 'to the longitudinal wires L, L' of the wire mesh mats M, M '. The bridge wire welding devices 30, 30 'are offset from one another on the outside of the two wire mesh mats M, M'. The now dimensionally stable component B ^{• is} further conveyed step by step from a downstream component conveying device 32 which essentially has two pairs of conveying elements 33, 33 'and 34, 34' opposite each other on both sides of the production channel 2. The protrusions of the bridge wires S, S 'protruding laterally beyond the wire mesh mats M, M' represent a considerable risk of injury when handling the component B, hinder the stacking of the components for transport and must therefore be separated so that the bridge wires S, S 'are as possible close flush with the longitudinal wires L, L '. With the aid of the first pair of conveying elements 33, 33 ', the component B is fed downstream, offset on the opposite sides of the production channel 2, edging devices 35, 35''which feed the wire mesh mats M, M' over the corresponding longitudinal wires L, L '. Cut off the web wire ends that protrude laterally with the longitudinal wires L, L '.

Within the scope of the invention it is possible to divide the finished, trimmed component B in the horizontal direction into at least two components, preferably of equal size, by means of horizontal cutting devices 36, 36 'connected downstream of the trimming devices 35, 35' on both sides of the production channel 2 , The horizontal cutting devices 36, 36 'are designed in such a way that they can cut through both the transverse wires Q, Q' of the wire mesh mats M, M 'and the insulating body W.

Within the scope of the invention, it is also possible, by means of the feeder device 21, to feed individual, cut-to-length insulating plates I and / or a plurality of vertically running, endless insulating material webs K to the guide device 22 in a plurality of webs running one above another in the vertical direction.

Furthermore, it is possible within the scope of the invention to insert the one-piece insulating plates I and / or the endless insulating material web K in the insulating material web cutting device 25 by means of an additional cutting tool in at least two sections or partial webs running one above the other in the vertical direction divide so that only the transverse wires Q, Q 'of the wire mesh mats M, M' are to be cut in the horizontal cutting devices 36, 36 '. According to the invention, it is also possible not to cut through the insulating material web cutting device 25 when cutting the insulating plate I or the insulating material web K completely, but only from both sides or only from one side of the insulating plate I or the insulating material web K as far as in cut this in that a web connecting the two parts remains in the insulating body W. In this case, only the transverse wires Q, Q 'of the wire mesh mats M, M' are severed in the horizontal cutting devices 36, 36 'and the final division of the finished component B into two or more component parts is carried out only at the construction site by breaking the connecting web between the insulating bodies ,

In order to keep the cross wire protrusions as small as possible when cutting the component B and to avoid further trimming of the component parts, it is possible within the scope of the invention, as shown in FIG. 2, the distances between the two central longitudinal wires C, C ' , between which the component B is severed, to be chosen correspondingly smaller than the remaining longitudinal wire division of the wire mesh mats M, M '.

The finished, trimmed component B is conveyed out of the production channel 2 with the aid of the second pair of conveyor elements 34, 34 'of the component conveying device 32 and transferred to a device shown in FIG. 4 for removal or stacking of several components.

The distance between the second pair of feed elements 20, 20 'of the wire mesh mat conveyor 18 and the first pair of conveyor elements 33, 33' of the component conveyor 32 and the distance between the pairs of conveyor elements 33, 33 'and 34, 34' must always be smaller than the smallest Length of the wire mesh mats M, M 'used to manufacture the component B, in order to ensure that the wire mesh mats M, M' are reliably conveyed between the wire mesh mat conveying device 18 and the component conveying device 32 and by 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 plates I the individual processing stations 11, 11 ';25; 26, 26 '; 29, 29 '; 30, 30 '; 35, 35 '; 36, 36 'safely and trouble-free feed. To ensure this, the wire mesh insert devices 10, 10 ', the pairs of feed elements 19, 19'; 20, 20 'of the wire mesh mat conveyor 18, the conveyor element pairs 33, 33'; 34, 34 'of the component conveying device 32 and the insulating body conveying device 24 are driven by a central main feed drive 37, all elements 19, 19'; 20, 20 '; 33, 33 '; 34, 34 'and the wire mesh insert device 10, 10' are connected to each other with the aid of articulated drive shafts 38, 38 '. The feed steps take place in cycles, because the insertion of the web wires S, S ', the welding of the web wires S, S' to the wires of the wire mesh mat M, M 'and the trimming of the web wire end parts each when the wire mesh mats M, M', of the insulating body W are at a standstill or component B take place. The length of the feed steps can be selected according to the cross wire division or an integer multiple of the cross wire division.

By widening the production channel 2 and corresponding lateral or individual adjustment of the feed elements 19, 19 '; 20, 20 ', the conveyor elements 33, 33'; 34, 34 'and the elements of the processing stations 25; 26, 26 '; 29, 29 '; 30, 30 '; 35, 35 '; 36, 36 ', components B with different predetermined widths can be produced.

The insulating body conveyor device 24 shown schematically in FIG. 2 has a conveyor chain 39 which is driven by the main feed drive 37 in the direction of the arrow P8 and which defines the conveying path of the insulating bodies W within the production channel 2. The conveyor chain 39 carries a plurality of carrier carriers 40, each of which is provided with a carrier 41 ^' . The drivers 41 are angular, hook-shaped or designed like a spike in order to establish a secure connection to the underside of the insulating body W and thus to prevent any slippage between the insulating body W and the carrier carriers 40 when the insulating body W is advanced. When the insulating bodies W are fed in a plurality of tracks lying one above the other, the insulating body conveying device 24 has a further upper conveyor chain 39 'with corresponding driver carriers 40' and drivers 41 'which engage on the upper side of the insulating body W of the uppermost insulating body track. The feed elements 19, 20 of the wire mesh mat conveying device 18 shown schematically in FIG. 2 have a shaft 42 inclined to the vertical, which is driven by a bevel gear 44 via a coupling 43 and is mounted in a counter bearing 45. The angular gear 44 is driven by the main feed drive 37 via the drive shaft 38. Each shaft 42 is provided with a plurality of transport disks 46 which are arranged at a mutually adjustable distance and which are rotatable for adjustment on the shaft 42 and are fixedly connected to the shaft 42 by means of a clamping element 47 after the adjustment.

As shown in FIG. 3a, the transport disks 46 have a plurality of grid engagement recesses 48, which are regularly distributed over the circumference, with a selectable depth, so that flattened teeth 49 are formed. The number of mesh engagement recesses 48 becomes corresponding to the cross wire division of the wire mesh mats

M, M 'selected such that the cross wires Q, Q' of the wire mesh mats M, M 'are securely gripped by the transport disks 46 and the slip-free feed of the wire mesh mats M, M' is ensured. As a result of the inclined position of the shafts 42, the transport disks 46 of each feed element 19 engage

19 '; 20, 20 'not only on one, but on several transverse wires Q, Q' of the wire mesh mats M, M ', so that the tensile force is distributed over several wires and these are therefore not too heavily loaded when the wire mesh mats M, M' are advanced - the. The inclination of the shafts 42 also ensures a continuous and slip-free further transport of the wire mesh mats M, M 'of successive components B, the successive wire mesh mats in the joint region being able to have distances which arise, for example, when trimming the wire mesh mats M, M' or when parts are removed from the wire mesh webs G, G '.

The conveyor elements 33, 33 '; 34, 34 'of the component conveying device 32 are analogous to the feed elements 19, 19'; 20, 20 'of the wire mesh mat conveyor 18 is constructed. Only the transport disks 46 have lattice engagement recesses 48 with a smaller depth. The wire mesh insert devices 10, 10 'have essentially the same elements as the feed elements 19, 20 of the wire mesh mat conveying device 18 shown in FIG. 2. The only difference is that, as shown in FIG. 3b, the mesh engagement recesses 48 in FIG Transport discs 50 are significantly deeper so that they have pointed teeth 51. This shape of the teeth 51 ensures that the teeth 51 which engage from the side in the non-guided wire mesh web G, G 'securely grasp the transverse wires Q of the wire mesh webs G, G' and advance the wire mesh webs G, G 'without slippage.

It is possible to use the system according to the invention to produce components B in which the wire mesh mats M, M 'have different structures, ie different line wire partitions and / or cross wire partitions as well as different diameters of the line wires and / or cross wires. However, the different cross wire divisions must correspond to integer multiples and can be, for example, 50, 100 or 150 mm. A further restriction is that it must be ensured that the web wires S, S 'can be positioned in such a way that they can be securely welded to the longitudinal wires of the two wire mesh mats M, M' despite these different wire pitches and wire diameters.

It is possible to use the system according to the invention to produce components B in which one and / or both wire mesh mats M, M 'protrude beyond the insulating body W on one or both sides running parallel to the production direction P4. In order to achieve this either the carriers 41 are raised or extended in this way, or the conveyor track of the conveyor chain 39 is raised such that the lower side surface of the insulating body W, which runs parallel to the production direction P4, is raised accordingly, as a result of which one and / or both wire mesh mats M, M 'on this side Form the desired supernatant. The conveying path of the upper conveyor chain 39 ′ arranged on the upper side of the insulating body W must be lowered accordingly or the drivers 41 ′ must be lowered or extended accordingly. In order to produce components B in which the insulating bodies W protrude beyond the two wire mesh mats M, M 'on one or both sides or sides running parallel to the production direction P4, the conveyor path of the lower conveyor chain 39 is lowered in this way and, if appropriate, the conveyor path of the upper conveyor chain 39 'raised such that the lower and optionally the upper side surface of the insulating body W, which runs parallel to the production direction P4, is correspondingly lowered or raised, as a result of which the insulating body W has the two wire mesh mats M, M' on one or both sides with the desired projections surmounted.

The continuous production of the components B with the aid of the system according to the invention is preferably carried out in such a way that the wire mesh mats M, M 'of successive components B are separated from one another only by a negligibly narrow joint between the longitudinal wires of successive wire mesh mats M, M' and also the corresponding associated insulating bodies W. successive components B follow one another without significant gaps.

Within the scope of the invention, however, components B can also be produced in which one and / or both wire mesh mats M, M 'protrude the insulating body W on one or both sides, perpendicular to the production direction P4. If one or both wire mesh mats M, M 'are to protrude from the insulating body W on both sides, the insulating bodies W of adjacent components B are fed from the feeder device 21 to the production channel 2 at appropriately selected intervals and are advanced there at these mutual intervals. When using an endless insulating material web K, a section corresponding to this distance must be separated from the web K when the insulating bodies W are separated. The two joints between the wire mesh mats M, M 'of successive components B are either exactly opposite or laterally offset from one another.

To produce components B, in which the insulating bodies W protrude beyond the two wire mesh mats M, M 'on one or both sides, running perpendicular to the production direction P4, the wire mesh mats M, M' are advanced with a predetermined distance in the production channel 2. To produce this selectable distance between the wire mesh mats M, M 'of successive components B is by the

Wire mesh mat scissors 11, 11 'when producing the wire mesh mats M, M' cut a section corresponding to this distance from the endless wire mesh webs G, G '. The size of the distance is limited by the fact 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 42 of the wire mesh mat conveying device 18 and the component conveying device 32 in order to prevent slippage To ensure feed of the wire mesh mats M, M 'of successive components B.

With large distances between adjacent rows of bridge wire

R1 and R2 can also be two or more in the context of the invention

Bridge wire welding devices 30 or 30 'per side surface, in

Feed direction P4 of the wire mesh mats M, M 'can be arranged one behind the other as seen. Here are the welding gun levers 66 and 67 and the welding electrodes 69 are designed such that only one bridge wire S is welded to a corresponding longitudinal wire L, L 'per pair of welding guns 31, 31'.

In order to increase the production speed, several trimming devices can also be arranged one behind the other in the horizontal direction in the context of the invention on each side surface of the component.

The insulating material supply device 52 has an insertion device 55 which supplies the insulating plates II intended for forming the insulating body W of the component B in accordance with the direction of the arrow P9 of the production line XX of the installation. The insulating plates II are provided on one end face with a groove N and on the other opposite end face with a tongue F, tongue and groove being designed and the insulating plates II being arranged such that the tongue of an insulating plate II is positively and non-positively in the groove a subsequent insulating plate II 'fits. The insertion device 55 consists of two working cylinders 56, the piston rods of which are moved in accordance with the double arrow P10 and are provided with a pressure plate 57 at their end. A conveyor belt 58 is arranged in the production line XX, which can be driven in the production direction P4 with the aid of a conveyor drive 59 and advances the insulating plate II in this direction along the production line XX. A transversely displaceable stop frame 61 is fastened to a frame 60, which limits the feed movement P9 of the insulating plates II and exactly fixes the position of the insulating plates II in the production line XX. sets. A feed device 62, for example a working cylinder, is arranged on the inlet side of the conveyor belt 58. The piston rod of the working cylinder 62 can be moved in accordance with the double arrow P4 and is provided with a pressure plate 63 which is matched to the end face of the insulating plate II which is provided with a groove. With the aid of the feed device 62, the insulating plate II 'located on the conveyor belt 58 is additionally advanced in accordance with the arrow P1 in order to move the insulating plate II' relative to the insulating material web K already formed and thus the insulating plate II 'with a positive and non-positive fit at the end to connect the insulating material web K and to produce an endless, coherent insulating material web K. Here, the tongue of the insulating plate II 'engages in the groove of the terminal element of the insulating material web K. The grooves and tongues are coordinated with one another in their design in such a way that a positive and non-positive clamping connection is created, which both aligns the insulating plates II, II 'as well as their firm connection with each other. Connected to the conveyor belt 58 is the conveyor chain 39 which extends over the entire production line XX and can be driven in accordance with the production direction P4 and which moves the insulating material web K in the production line XX in cycles in accordance with the production direction P4. The transition point between the conveyor belt 58 and the beginning of the conveyor chain 39 is laterally delimited by side plates 64, 64 ', in order to avoid lateral deflection of the insulating plates II' when connecting adjacent insulating plates II 'to form the insulating material web K. The distance between the side plates 64, 64 'is adjustable in order to ensure the tightest possible guidance even with different thicknesses of the insulating plates II'. In the context of the invention, it is possible to provide additional clamping elements which engage on the insulating material web K and which additionally fixes the insulating material web K when the insulating plate II 'is connected. The wire mesh mat M is formed in the following manner in accordance with the exemplary embodiment described in FIG. 1: A wire mesh web G standing upright is drawn off from a supply reel 3 in accordance with the direction of the arrow P1 with the aid of the wire mesh web insert device 10, which essentially consists of a corresponding to the double arrow P12 drivable feed roller 10, and fed to a straightening device 5. The straightening device 5 consists of two rows of straightening rolls 6 and deliverable eccentric rolls 8 which are offset from one another. In the exemplary embodiment shown, the wire mesh mat shears 11 work in such a way that they cut out a selectable section from the wire mesh web G in a so-called gas cut so that the wire mesh mats M fed to the production line XX follow one another at a distance. Within the scope of the invention, however, it is also possible to design and control the wire mesh mat shears 11 in such a way that a separating cut or a trimming cut is carried out.

The wire mesh mat M reaches the production line XX via the guide devices (not shown) and is there at a distance and parallel to the insulating material web K with the aid of two pairs of conveying elements 19, 19 'which can be driven in accordance with the arrows P13, P13'; 20, 20 'in the production direction P4 step by step along the production line XX together with the insulating body web K the downstream processing devices 26, 26'; 30, 30 'and 35, 35' fed. Already prefabricated ^' wire mesh mats M' are supplied with the aid of the wire mesh mat feed device 53 'in the following manner: wire mesh mats M' are removed and removed from a stack of mats 65 'with the aid of a conveyor 66' which can be pivoted in accordance with the double arrow P14 ' stored in a receiving rail 67. With the help of an insert Device 68 'is fed the wire mesh mats M' one after the other in the direction of the arrow P15 'via a skin pass device 69' to a feed roller 70 'which can be driven in accordance with the double arrow P16'. The insertion device 68 'consists, for example, of a working cylinder, the piston rod of which can be moved in accordance with the double arrow P17' and which is provided with a gripper 71 for gripping the wire mesh mat M '. The wire mesh matting device 69 'has dressing rollers 72 and eccentric rollers 73 arranged offset from one another. The feed roller 70 'pushes the wire mesh mats step by step into the production line X-X, where they are spaced apart and parallel to the insulating material web K and together with this with the aid of the conveyor element pairs 19, 19'; 20, 20 'in the production direction P4 step by step along the production line XX the downstream processing devices 26, 26'; 30, 30 'and 35, 35' are supplied.

In the web wire feed devices 26, 26 ', a plurality of wires D, D' are simultaneously fed from both sides in accordance with the arrow directions P6 and P6 'and as web wires S, S' in the horizontal direction at a selectable angle through the meshes of the wire mesh mats M, M 'and pushed through the insulating material web K, the web wires S, S' with their two ends each abutting the corresponding wires L, L 'or Q, Q' of the wire mesh mats M, M 'with a slight lateral protrusion. In the context of the invention, the bridge wires S, S 'can be separated from a wire supply with the aid of suitable scissors or can also be fed to the bridge wire feed devices 26, 26' as straight, straight rods. With the help of the pairs of conveying elements 19, 19 '; 20, 20 ', the wire mesh mats M, M' are fed together with the insulating material web K fed by means of the conveyor chain 39 and equipped with the bridge wires S, S 'to the downstream bridge wire welding devices 30, 30' in which the bridge wires S, S 'are each provided the corresponding wires L, L 'or Q, Q' the Wire mesh mats M, M 'are welded. The lattice body H formed in this way, together with the insulating body web K, is driven with the aid of two pairs of conveying elements 33, 33 '; 34, 34 'fed to the downstream trimming devices 35, 35', in which the web wire protrusions projecting beyond the wires L, L 'or Q, Q' of the wire mesh mats M, M 'are cut off flush.

With the aid of the pairs of conveying elements 33, 33 '; 34, 34 ', the grid body H is fed together with the insulating material web K to the cutting device 25'. The cutting device 25 'separates the insulating body W from the insulating material web K in a selectable length and has at least one cutting disk 75 which can be driven by means of a cutting drive 74. A further cutting drive 74 'including cutting disc 75 can be used to increase the cutting performance. The cutting device 25 'is synchronized with the feed movements of the conveyor element pairs 19, 19'; 20, 20 'and 33, 33'; 34, 34 'moved according to the direction of production P4 and, after the cut has been made, returned to the starting position, these movements taking place according to the double arrow P19. The entry into the cutting position in the corresponding return from the cutting position takes place according to the double arrow P20. In the context of the invention, the length of the insulating body W can correspond exactly to the length of the wire mesh mats M, M ', so that the cutting device 25' has to cut a corresponding piece out of the insulating material web K in a so-called gas cut. It has proven to be advantageous, however, to let the insulating body W protrude somewhat beyond the wire mesh mats M, M ', so that when components B are used, there is almost continuous insulation in the components

B formed walls is reached.

The finished component B is fed by a conveyor 77 provided with a correspondingly designed gripper 76 along the production line XX to a cross conveyor 78. The conveyor 77 can, for example, from a working cylinder which consist of a piston rod which can be moved in accordance with the double arrow P21. The cross conveyor 78 pushes the finished components B according to the direction of the arrow P22 from the production line XX.

According to this exemplary embodiment, insulating plates 12 are used which have flat end faces E in comparison to the insulating plates II, II 'described in FIG. 4. The insulation plates 12 are fed into the production line X-X on the conveyor belt 58 via the insertion device 55. To produce an endless insulation material web K, the insulation plate 12 'is connected to the insulation material web K by means of heat welding with the aid of a heating device 80. The heating device 80 essentially consists of a heating plate 81 and a heating transformer 82 used to heat the heating plate 81.

The endless insulating material web K is produced in the following way: The insulating plate 12 'located on the conveyor belt 58 is advanced with the aid of the feed device 62 in accordance with the arrow P4 until the insulating plate 12' is placed on the heating plate 81 resting on the end face of the insulating material web K. abuts. The heating plate 81 is then heated with the aid of the heating transformer 82 until the abutting end faces of the insulating material web K and the insulating plate 12 'are softened. The heating plate 81 is then quickly pulled out of the space between the insulating plate 12 'and the insulating material web K in the corresponding arrow direction of the double arrow P24, and the insulating plate 12' is advanced somewhat by means of the feed device 62 in accordance with the production direction P4, so that the heated end faces face each other to press and thus the To weld insulating plate 12 'to the insulating material web K and thus to connect it in a positive and non-positive manner. Since the insulating material web K is conveyed step by step by the conveyor belt 58, in time with the entire production system, in accordance with the direction of production P4, the heating device 80 is also moved during the heating step by step in accordance with the corresponding arrow direction of the double arrow P25 and after the heating plate 45 has been pulled out moved back to the starting position in the corresponding opposite direction of the double arrow P25.

In the context of the invention, it is possible, as shown in FIG. 5, to arrange the cutting device 25 for severing the insulating material web K directly behind the heating device 80 and before feeding the wire mesh mats M, M 'into the production line X-X. Since the cutting device 25 is also conveyed step by step through the conveyor chain 39 in step with the entire production system in accordance with the production direction P4 when the insulating material web K is cut, the cutting device 25 is also moved step by step according to the corresponding arrow direction of the double arrow P19 and after the end of the cut moved back to the starting position in the corresponding opposite direction of the double arrow P19. The conveyor chain 39 conveys the insulating bodies separated from the insulating material web K by W in the direction of production P4 into the subsequent processing devices of the system.

Since the conveyor chain 39 must not extend into the movement paths of the heating device 80 and the cutting device 25, the insulating material path K is supported in this area by at least two support elements 83 which - with the help of a working cylinder 84 corresponding to the double arrow P26 from the movement path of the heating device 80 and the cutting device 25 can be moved.

In the context of the invention, it is possible, as shown in FIG. 5, two supply spools 3, 3 'with wire mesh webs G, G 'to be provided to create the wire mesh mats M, M'. The corresponding elements have the same reference numbers, which are provided with or without an apostrophe. 6 shows the inlet area of a further exemplary embodiment of a system according to the invention. According to this exemplary embodiment, the insulating plates 12 already described in FIG. 5 are also used. The insulation plates 12 are fed into the production line XX on the conveyor belt 58 via the insertion device 55. To produce an endless insulation material web K, the insulation plate 12 'is connected to the insulation material web K by gluing with the aid of an adhesive device 85. The adhesive device 85 has a spray nozzle 86 together with the storage container, which is filled with a suitable adhesive. The adhesive must be suitable for gluing the material of the insulating plates 12 and must have a drying time which is matched to the production speed in order to ensure a secure connection of the insulating plate 12 'to the insulating material web K. The adhesive device 85 can be moved in the horizontal direction and in the vertical direction in accordance with the double arrow P27. To spray the adhesive onto the end face E of the insulating plate 12, the adhesive device 85 is moved in accordance with these directions of movement. In order to accelerate the application of the adhesive, several adhesive devices 85 can also be used simultaneously within the scope of the invention. Within the scope of the invention it is also possible to spray several insulating plates 12 with adhesive at the same time.

In this exemplary embodiment, the endless insulating material web K is produced in the following way: Immediately before the

When the insulating plate 12 is fed into the production line XX, an end face E of the insulating plate 12 is provided with adhesive. With the aid of the feed device 52, the insulating plate 12 is first advanced into the production line XX in accordance with the direction of the arrow P9 and placed on the conveyor belt 58. On- finally, the insulating plate 12 'is advanced somewhat with the aid of the feed device 62 in accordance with the production direction P4 in order to press the adhesive end face of the insulating plate 12' against the end face of the insulating material K and thus the insulating plate 12 'with the insulating material web K connect.

6 shows a further exemplary embodiment of a cutting device 25 for separating the insulating body W from the insulating material web K. The cutting device 25 has a straight guide carriage 87 which can be displaced along a rail 88 in accordance with the double arrow P14, the movement in the production direction P4 taking place synchronously with the advance of the insulating material web K. A cutting wire 89 is fastened to the straight guide carriage 87 and, according to the double arrow P28, can be moved transversely to the insulating material web K and can be heated with the aid of a heating transformer 90. To separate the insulating body W from the insulating material web K, the heated cutting wire 89 is correspondingly moved through the insulating material web K and reaches the position shown in broken lines in FIG. 6. After the cut, the straight guide carriage 87 together with the cutting wire 89 is moved back to its starting position.

In the context of the invention it is possible to replace the cutting device 25 'shown in Fig. 4 by the cutting device described above, i.e. to arrange the cutting device described above after the trimming devices 35, 35 '.

Within the scope of the invention, it is possible, as shown in FIG. 6, to provide two stacks of mats 65, 65 'with wire mesh mats M, M ¹ . The corresponding elements have the same reference numbers, which are provided with or without an apostrophe.

It goes without saying that the exemplary embodiments shown differ in the context of the general inventive concept, in particular with regard to the design and configuration leadership of the devices for connecting the insulating plates to form an endless web of insulating material can be modified. If appropriate adhesives are used, both the end face of the insulating plate and the end face of the insulating material web 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 of the insulating plates to be connected with a self-adhesive film. The film can already be attached during the manufacture of the insulating plates and is expediently protected by a removable film.

Furthermore, it is possible within the scope of the invention to additionally provide the tongue and groove end face of the insulating plates with an adhesive in order to ensure a secure connection of the insulating plates.

The end faces of the insulating plates which are adjacent to form the insulating material web can also be provided within the scope of the invention with other form-fitting and non-positively interacting clamping connecting elements which are, for example, dovetail-shaped.

Furthermore, it is possible within the scope of the invention to use other cutting methods and devices for separating the insulating body from the insulating material web. These methods and devices must be matched to the material properties of the insulating materials and ensure that the cut results in edges that are as smooth as possible and that the properties of the material of the insulating body are not impaired, for example melted. The component shown in ^'Fig. 7 ^in' axonometric view consists of an outer and an inner wire mesh mat M and M ', which are arranged at a predetermined distance parallel to each other. Each wire mesh mat M and M' comprises a plurality of longitudinal wires L and L 'and from several cross wires Q and Q ¹ , which cross each other and on the cross points are welded together. The mutual distance between the longitudinal wires L, L 'and the transverse wires Q, Q' to one another is selected in accordance with the structural requirements for the component. The distances are preferably of the same size, for example in the range from 50 to 150 mm, so that the respectively adjacent longitudinal and transverse wires form square meshes. In the context of the invention, the meshes of the wire mesh mats M, M 'can also be rectangular and have, for example, short side lengths of 50 mm and long side lengths in the range from 75 to 100 mm.

The diameters of the longitudinal and transverse wires L, L 'and Q, Q' can also be selected in accordance with the static requirements and are preferably in the range from 2 to 6 mm. The surface of the wires L, L '; Q, Q 'of the wire mesh mats M, M' can be smooth or ribbed in the context of the invention.

The two wire mesh mats M, M 'are connected to one another by a plurality of bridge wires S, S' to form a dimensionally stable grid body A. The web wires S, S 'are welded at their ends to the wires of the two wire mesh mats M, M', whereby in the context of the invention the web wires S, S 'are either, as shown in FIG. 7, with the respective longitudinal wires L. , L 'or with the cross wires Q, Q' are welded. The bridge wires M, M 'are alternately inclined, i.e. arranged in the manner of a truss, whereby the lattice body is stiffened against shear stress.

The spacing of the bridge wires M, M 'from one another and their distribution in the component depend on the structural requirements on the component and are, for example, 200 mm along the longitudinal wires and 100 mm along the transverse wires. The mutual distances between the web wires M, M '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 from 3 to 7 mm, with the diameter of the bridge wires S, S 'being preferred in the case of components with thin longitudinal and transverse wires. is chosen larger than the diameter of the longitudinal and transverse wires.

The spatial lattice body A formed from the two wire mesh mats M, M 'and the web wires S, S ¹ must not only be dimensionally stable, but also, in its preferred use as a wall and / or ceiling element, also perform the function of a spatial reinforcement element, ie shear and absorb pressure forces. For this reason, both the longitudinal and transverse wires are mutually one another, as is customary in the case of reinforcement mats, and the land 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 welding nodes. In order to be able 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 'are made of suitable materials and have corresponding mechanical strength values so that they are used as reinforcement wires for the wire mesh mats M, M' to be used as mesh reinforcement mats or as the two wire mesh mats M, M '' connecting reinforcing wires can be 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, the top surfaces 91 and 91' of which run parallel to the wire mesh mats M, M '. The insulating body W serves for thermal insulation and sound insulation and consists, for example, of foam plastics, such as polystyrene or polyurethane foam, foams based on rubber and rubber, lightweight concrete, such as autoclave or gas concrete, porous plastics, porous substances based on rubber and rubber, pressed slag, plasterboard , cement-bound press plates made from wood chips, jute, hemp and sisal fibers, rice husks,

In the context of the invention, the insulating body W can also consist of bioplastics, for example from algae foam, which is made from foamed algae or algae pulp.

The insulating body W can be provided with pre-drilled holes for receiving the bridge wires S, S '. The insulating body W can also be provided on one or both sides with a plastic or aluminum layer serving as a vapor barrier. The position of the insulating body W in the component is determined by the inclined web wires S, S 'which penetrate the insulating body W. The thickness of the insulating body W is freely selectable and is, for example, in the range from 20 to 200 mm. The distances between the insulating body W and the wire mesh mats M, M 'can also be freely selected and are, for example, in the range from 10 to 30 mm. The component can be produced in any length and width, a minimum length of 100 cm and standard widths of 60 cm, 100 cm, 110 cm and 120 cm having proven advantageous on the basis of the production process.

The through holes 92; 93, 93 'are drilled into the insulating body W or punched out of it. In the context of the invention, it is also possible, in the production of the insulating body W, to shape the through holes 92; 93, 93 'to be left out. The directions of the inclined through-holes 93, 93 'are selected in such a way Ge, ^that' when using the device as a perpendicular wall, at least the through holes 93, 93 'of a type extending obliquely from top to bottom, wherein the directions parallel to the longitudinal wires L, L 'and / or run parallel to the cross wires Q, Q' of the wire mesh mats M, M '. The number, dimensions and distribution of all through holes 92; 93, 93 'can be freely selected. The number and dimensions should not be too large to match the thermal insulation values of the

Component not to deteriorate too much. The number is, for example, between two and six pieces per m 2. The shape of the through holes 92; 93, 93 'can also be selected as desired and can be, for example, square, rectangular or round. With a round cross section of the through holes 92; 93, 93 ', the diameters are preferably in the range from 50 to 100 mm. The distribution of the through holes 92; 93, 93 'in the component can be regular or random in the context of the invention, with a random and asymmetrical distribution of the through holes 92; to avoid resonance effects. 93, 93 'is advantageous.

As can be seen from the top view of the component shown in FIG. 9, in the wire mesh mat M at the edge of the component B, the longitudinal wires L and the edge longitudinal wires L1 each fit flush with the edge cross wires Q1 and the cross wires Q and the edge cross wires Ql each flush with the longitudinal edge wires Ll. The same applies analogously to the wires L ', Ll'; Q ', Ql' of the other wire mesh mat M '.

FIG. 10 shows a side view of the component B viewed in the direction of the cross wire array. The web wires S, S 'are each welded to the longitudinal wires L and L' of the wire mesh mat M and M '. In this case, the web wires S running parallel in the transverse wire direction form a row Rl running perpendicular to the plane of the drawing and the corresponding web wires S 'form a further row R2 running perpendicular to the drawing plane, which runs in the opposite direction to the row Rl. The web wires lying in a plane S, S 'of different rows Rl, form which runs in Fig. 10 in parallel to the plane of a web wire row H, ^■. When the component B is produced in the systems according to the invention, the rows R1, R2 run in the vertical direction perpendicular to the production direction P4, while the ridge wire rows H run parallel to the production direction P4 in the horizontal direction. FIGS. 11 and 12 each show exemplary embodiments with different angles between the web wires S, S 'and the corresponding longitudinal wires L, L' of the wire mesh mats M, M ', wherein according to FIG. 11 also different angles within a row within a component of bridge wires are possible.

13 shows a component B in which in a row R1 the web wires S run in the same direction at an angle between the longitudinal wires L and L 'of the wire mesh mats M, M', while in the next row R2 the web wires S 'shown in broken lines also run in the same direction, however run in opposite directions between the corresponding longitudinal wires L, L ', ie the component has several rows of diagonally inclined bridge wires with changing direction from row to row. In the context of the invention, the rows of web wires aligned obliquely in the same direction can also run between the transverse wires Q, Q 'of the wire mesh mats M, M'.

14 shows a component B with oppositely inclined web wires S, S 'per row R1, R2, the spacing of adjacent web wires in the row being selected such that the ends of the web wires facing each other come as close as possible, which means that ll two bridge wires can be welded together in one work step with the corresponding grid wire.

15 shows, the insulating body W can also be arranged asymmetrically with respect to the two wire mesh mats M, M '. Here, the diameters of the wires L ', Ll'; Q ', Ql' of the wire mesh mat M 'lying further away from the insulating body W advantageously larger than the diameter of the wires L, Ll; -Q, Ql of the wire mesh mat M closer to the insulating body W.

In order to stiffen the grid body at its edges, additional, preferably perpendicular to the wire grid mats M, M 'and with the corresponding edge wires L1, Ll'; Ql, Ql 'of the wire mesh mats M, M' welded edge bridge wires S1 are provided. The diameter of the edge web wires S1 is preferably equal to the diameter of the web wires S, S '.

17 shows a component B according to the invention, the insulating body W of which on the side surfaces 94 running parallel to the transverse wires Q, Q 'does not end with the two wire mesh mats M, M', but is laterally surmounted by them. With this embodiment, when two identical components are linked, the insulating bodies of adjacent components can be arranged without a space, while the wire mesh mats of the two components overlap one another and thereby form a load-bearing overlap joint. Analogously, the wire mesh mats M, M 'can laterally protrude laterally from the side surfaces 94' running parallel to the longitudinal wires L, L '.

In the context of the invention, the insulating body W can also end flush on all side surfaces 94, 94 'with the inner wire mesh mat M' and only protrude beyond the outer wire mesh mat M in practical use. Analogously, it is possible within the scope of the invention that the insulating body W is flush on all side surfaces 94, 94 'with the outer wire mesh mat M and only projects beyond the inner wire mesh mat M' in practical use.

One or both of the wire mesh mats M, M 'can also protrude laterally from the insulating body W on all side surfaces 94, 94' thereof. In all the exemplary embodiments, any edge web wires S1 can be arranged in such a way that they run outside the insulating body W or connect flush to the side of the latter.

The thickness of the outer shell 96 is selected in accordance with the static and the sound and thermal requirements for the component B 'and is, for example, 20 to 200 mm. If component B 'is used as a ceiling element, the minimum thickness of the outer shell 96 must be 50 mm for structural reasons.

On the inner wire mesh mat M 'intended to form the inside of the component, an inner shell 97 is applied, which adjoins the insulating body W, W', surrounds the inner wire mesh mat M 'and consists, for example, of concrete or mortar. The thickness of the inner shell 97 is selected in accordance with the static and the sound and thermal requirements for the component B 'and is, for example, 20 to 200 mm. The two shells 96, 97 are preferably applied at the place of use of the component B ', for example sprayed on using the wet or dry method.

Since the partial areas of the land wires S, S 'and possibly also the edge land wires S1 lying in the interior of the component B' are not covered with concrete and are therefore exposed to corrosion, the land wires S, S 'or Sl must be provided with a corrosion protection layer. This is preferably achieved by galvanizing and / or plastic coating the bridge wires S, S ', Sl. In order to allow the web wires S, S ', Sl to be welded to the wires of the wire mesh mats M, M', however, the plastic layer must not cover the end regions of the web wires S, S 'or edge web wires S1. For reasons of cost, it has proven to be advantageous to use galvanized wire at least for the land wires S, S ', S1 during the manufacture of the grid body A. The web wires S, S ', Sl can also be made of stainless steel or of other non-corrosive materials, for example aluminum alloys, which must be connectable, preferably weldable, to the wires of the wire mesh mats M, M'.

This applies analogously to the case that the thick outer shell 96 'is reinforced only with the outer wire mesh mat M. The inner wire mesh mat M 'and the inner additional reinforcement mat 98' can be connected by a plurality of spacer wires 99, which preferably run perpendicular to the inner wire mesh mat M 'and inner additional reinforcement mat 98' and whose mutual, lateral spacing is freely selectable. The diameter of the spacer wires 99 is preferably the same as the diameter of the wires of the wire mesh mats M, M ¹ .

Within the scope of the invention, the outer additional reinforcement mat 98 and the outer wire mesh mat M can also be connected with spacer wires, which preferably run perpendicular to the outer wire mesh mat M and outer additional reinforcement mat 98.
