Depicted in FIG. 1, the apparatus according to the invention serves to manufacture the apparatus of FIG. 8 of the building element B consisting of two parallel, flat mesh mats M, M 'from intersecting and welded to each other at the intersection points of the longitudinal b, b' and transverse b, 6 'wires, from retaining mesh mats M, M' on a given reciprocal the distance of straight jumper wires 8, 8 ', which are welded to one wire of both mesh mats M, M' at each end, as well as from at least a partly insulating body located between the mesh mats M, M 'at a given distance from them V. for example insulating nd plate of plastic.

Depicted in FIG. 1 installation contains the main frame 1, which preferably is located in the middle marked only schematically horizontal, defining production line XX technological channel 2. At the entrance of the technological channel 2 is located the device 3 for supplying the insulating body V. On both sides of the technological channel 2, if you look in the direction of P1 production, there is one device 4, 4 'for feeding wire mesh cloths, one device 5, 5' for cutting mesh mats, one device 6, 6 'for feeding re sliver wires, one device 7, 7 'for welding jumper wires and one trimmer 8, 8'. At the output of the technological channel 2 is located, in addition, the transverse transport device 9 for building elements.

With the help of a feeding device, for example, driven along the double arrow P2, P2 'of the feed roll 10, 10' of devices 4, 4 'for feeding wire mesh cloths, two coils of wire on the edge are unwound from two rolls 11, 11' along arrows P3, P3 ' mesh sheets O, O ', and the mutual distance between the longitudinal b, b' and transverse b, O 'wires of each wire mesh sheet O, O', i.e. the so-called pitch of the longitudinal and transverse wires, as well as the width of each wire mesh sheet O, O ', can be freely selected within certain limits. Each device 4, 4 'for feeding the wire mesh fabric contains the correct device 1 2, 12', which is governed by the corresponding wire mesh fabric C, C and consists of several regular rolls arranged in two rows with an offset relative to each other 13, 13 '(Fig. 2) and the input eccentric rolls 14 (Fig. 2). The feed rolls 10, 10 'have the task of periodically feeding wire mesh cloths C, C' for further processing to series-connected devices 5, 5 'for cutting mesh mats along arrows P3, P3', or at the end of the production of removing unnecessary more wire mesh webs C, C 'in the direction against the arrows P3, P3' of the correct rolls 13, 13 '. Each feed roller 10, 10 'is rotatably mounted between the working position in which it is in contact with the retractable wire mesh fabric C, C', and the initial position in which it is out of contact with the wire mesh fabric C, C '.

Devices 5, 5 'for cutting mesh mats, as described with reference to FIG. 5a, 5b, are separated from the endless wire mesh sheets C, C ', respectively, the mesh mats M, M' of a given length. Due to the slightly curved, only elastically deforming mesh mats M, M 'and ending tangentially on opposite longitudinal sides of the technological channel 2 of the leading devices 15, 15' (Fig. 2), which consist, for example, of several arcuate planks located one above another and fixed by means of consoles and holders on the main frame 1, the mesh mats M, M 'are sent to the technological channel 2 in such a way that they fall into position parallel to each other at a mutual distance corresponding to the desired thickness not manufactured building element B. In the technological channel 2, both mesh mats M, M 'with the help of spacer retaining elements consisting, for example, of spacer plates and several spacer guides arranged in a vertical direction, one above the other, are always and exactly hold at that particular distance.

Using the transport device 16 for mesh mats, containing mainly two pairs of opposite each other, located on both sides of the technological channel 2 feed elements 17, 17 ', 18, 18', both mesh mats M, M 'are periodically transported in leading devices 15, 15 'in the direction P1 of production along the technological channel 2 to the connected processing areas 6, 6'; 7, 7 '; 8, 8 '; 9, 9 '. The first pair of feeding elements 17, 17 'is located in a parallel output area of the masters 15, 15'. The distance between the first pair of feeding elements 17, 17 'and devices 5, 5' for cutting mesh mats, as well as the distance between both pairs of feeding elements 17, 17 ', 18, 18' must be less than the minimum length intended for the manufacture of building element B mesh mats M, M ', in order to ensure reliable further transportation of the mesh mats M, M' transport device 1 6.

Depicted in FIG. 2 on an enlarged scale, the device 3 for supplying an insulating material serves to supply insulating plates I, for interconnecting them into the sheet K of insulating material and for separating the insulating body A from the sheet K of an insulating material. The device 3 for supplying the insulating material contains an inserting device 1 9, which feeds from the side the insulating plates I intended for the formation of the insulating body A of the building element B along the arrow P4 to the production line X-X of the installation. The retractor 19 consists mainly of two working cylinders 20, the piston rods of which are mounted to move along the double arrow P5 and are equipped with a pressure plate 21 at their end. In the production line XX, there is a belt conveyor 22 driven by an actuator 23 conveyor in the direction of P1 production and feeding the insulating plate I in this direction along the production line X-X. Using a transversely displaceable support frame 24, the movement P4 of the supply of the insulating plates I is restricted and the position of the insulating plates I is precisely set in the production line XX. On the inlet side of the belt conveyor 22, there is a feeding device 25, for example, a working cylinder 25. The piston rod of the working cylinder 25 is mounted for movement along the double arrow P6 and is provided with a corresponding end surface of the insulating plate I with a pressure plate. Using a feeding device 25, the insulating plate I ′ located on the conveyor belt 22 is further advanced along the arrow P1 so as to move the insulating plate I ′ relative to the already formed web K of insulating material, thereby connecting the insulating plate I ′ with geometric and force closure with the end of the web To the insulating material and form an infinite single web To the insulating material. The connection with the geometric closure means the connection of the insulating plates I, I ', which at the junction of both insulating plates I, I' has neither gaps nor lateral overlaps. The connection with the power closure means the connection of the insulating plates I, I ', in which the junction does not diverge under the influence of tensile and compressive loads.

To connect the insulating plates I ′ with the already formed web K of the insulating material, a connecting device 26 is located in the exit zone of the belt conveyor 22. The connecting device 26 is arranged to move along the double arrow P7 across the production line X-X and along the double arrow P8 parallel to the production line X -H. According to this exemplary embodiment, insulating plates I, I 'are used, having flat end surfaces P. on their narrow sides. To form an endless web to an insulating material, an insulating plate I' is insulated, for example by heat sealing using a connecting device made in the form of a heating device 26, is connected to the web of insulating material. The heating device consists mainly of a heating plate and a heating transformer used for heating the heating plate. The endless web To the insulating material is created as follows. The insulating plate I ′ located on the belt conveyor 22 is advanced in the direction of arrow P6 by means of the feeding device 25 until the insulating plate I ’is pressed into the heating plate adjacent to the end end surface of the sheet K of the insulating material. Then, the heating plate is heated by the heating transformer until the adjacent end surfaces of the web K of the insulating material and the insulating plate I ′ are softened. Thereafter, the heating plate in the corresponding direction of the double arrow P7 is quickly pulled out from the gap between the insulating plate I 'and the sheet K of the insulating material, and the insulating plate I' is slightly advanced in accordance with the production direction P6 by means of the feeding device 25 in order to press the heated end surfaces to each other and, thereby, weld the insulating plate I 'with the sheet K of the insulating material and, therefore, connect with a geometric and force closure. Since the sheet K of the insulating material is periodically transported further along the conveyor belt 22 to the tact of the entire production plant in the production direction P1, the connecting device 26 also periodically moves in the corresponding direction of the double arrow P8, and after removing the heating plate in the corresponding opposite direction The double arrow P8 returns to its original position.

According to another exemplary embodiment for the formation of an endless web K of insulating material, the insulating plate I ′ is connected to the web K of insulating material by gluing with a connecting device 26 made in the form of a gluing device. The gluing device contains, for example, a nozzle and a reservoir filled with a suitable adhesive. The adhesive must be suitable for bonding the material of the insulating plates I, I 'and have a drying time consistent with the production speed to ensure a reliable connection of the insulating plate I' with the sheet K of the insulating material. The gluing device is arranged to move in horizontal and vertical directions for spraying the glue on the end surface P of the insulating plate I '. To speed up the application of glue in the framework of the invention can also be used at the same time several gluing devices. In the framework of the invention, it is also possible to spray the glue simultaneously on several insulating plates I '. The endless web To the insulating material is created in this exemplary embodiment as follows. Immediately before the supply of the insulating plate I 'to the production line XX, the end surface P of the insulating plate I is provided with glue. The insulating plate I ′ is first pushed along the side of arrow P4 into the production line XX using the insertion device 19 and placed on the conveyor belt 22. Then the insulating plate I ′ is slightly advanced in the production direction P1 using the feeding device 25 so that it is equipped with glue end surface P of the insulating plate I 'is pressed against the end end surface of the web To the insulating material and connect, thereby, the insulating plate I' with the web To the insulating material with geometric and force closure.

In the framework of the invention, the insulating plates I, I 'can have a groove P on one end surface and a ridge on the other opposite end surface P', and the groove and the ridge are designed so that the crest of one insulating plate I fits with a geometrical and force closure the groove of the next insulating plate I '. Due to the relative movement along the arrow P6, the ridge of the insulating plate I 'enters the groove of the end element of the already formed web K of the insulating material. The grooves and ridges are coordinated with each other in their execution with the possibility of forming a clamping connection with a geometric and force closure, which ensures both the alignment of the connecting insulating plates I, I ', and their strong connection with each other. The connecting device 26 in this example execution is not valid.

In the framework of the invention, the end surfaces P of the insulating plates I, I ', which are provided with a groove and a tongue, can additionally be provided with an adhesive to ensure a reliable connection of the insulating plates. In the framework of the invention, the adjacent end surfaces of the insulating plates I, I 'for the formation of the K insulating material can also be provided with other clamping connecting elements cooperating with the geometric and force closure, for example, in the form of a dovetail.

It is clear that the depicted embodiments in the framework of the general idea of the invention can be modified in different ways, in particular with regard to the implementation of devices for connecting insulating plates I, I 'in order to form an endless web K of insulating material. When using appropriate adhesives, both the end surface P of the insulating plate I, I 'and the end end surface of the sheet K of the insulating material can be provided with glue.

In addition, in the framework of the invention it is possible to provide one or both of the joined flat end surfaces P of the insulating plates I, I 'with a self-adhesive film. The film can be placed already in the manufacture of insulating plates I, I 'and is expediently protected by a detachable film.

The belt conveyor 22 is adjacent to a transport device passing through the entire production line X-X, for example a chain conveyor 27 driven in the direction P1 of production and driving the web To the insulating material and the insulating bodies A in the production line X-X in the direction P1 of production.

The device 3 for supplying an insulating material contains a device 28 for cutting a sheet of insulating material that moves along the double arrow P9 across the production line X-X and along the double arrow P10 parallel to the production line X-X. The cutting device 28 separates from the blade K of the insulating material an insulating body A of a selectable length and contains at least one separating disk 30 driven by the cutting drive 29. To increase the cutting performance, an additional cutting drive 29 ′ can be used together with the separating disk 30. When the cutting device 28 cutting moves synchronously with the direction of movement of the chain conveyor 27 in the direction P1 of production and after making the cut returns to its original position, and these movements occur along d war arrow P10. Enter into the cutting position and the corresponding conclusion from the cutting position occur along the double arrow P10.

In the framework of the invention, other cutting methods and cutting devices can be used to separate the insulating body A from the web K of the insulating material. These methods and devices must be consistent with the properties of insulating materials and ensure that the incision forms as smooth edges as possible and that the material of the insulating body does not deteriorate in its properties, for example, does not melt. In particular, a cutting wire moved across the web K of insulating material and heated by a heating transformer can be used as a device for cutting the web of insulating material.

Since the cutting device 28, when cutting the web To the insulating material, is transported further by means of a chain conveyor 27 periodically to the full production unit in the production direction P1, the cutting device 28 also periodically moves in the corresponding direction of the double arrow P10 and, after the cutting is completed, returns to its original position in the corresponding opposite direction of the double arrow P10. The chain conveyor 27 transports the insulating bodies A separated from the web to the insulating material in the production direction P1 to the subsequent processing devices of the plant.

Since the chain conveyor 27 must not reach the trajectories of the connecting 26 and the cutting device 28, the web To the insulating material in this area is supported by at least two supporting elements 31, which with the help of the working cylinder can move along the double arrow P11 from the trajectory of the connecting 26 and cutting 28 devices.

In the framework of the invention, it is also possible to provide additional clamping elements acting on the sheet K of the insulating material, which, when the insulating plate I ′ is joined to the already formed sheet K of the insulating material, additionally fix it.

On both sides of the technological channel 2 after the leading devices 15, 15 'there is one device 6, 6' for supplying jumper wires, with which simultaneously on both sides of the technological channel 2 periodically from reels 32, 32 'with a supply of wires along the arrows P12, P12 'is unwound several wires Ό, Ό', is straightened by means of a training device 33, injected horizontally into the gap between the two mesh mats M, M ', pierced like a nail through the insulating body A and separated from the wire stock. Punching the insulating body A is greatly facilitated by heating the edges of the jumper wires 8, 8 ', and the heating occurs, for example, by means of an inductive heating device.

In the framework of the invention, it is further possible to arrange all devices 6, 6 'for supplying the jumper wires on one side of the technological channel 2 one after the other in the production direction P1.

In the framework of the invention, it is possible to feed previously cut off jumper wires 8, 8 'to the mesh mats M, M' on the side of the technological channel 2 by vertically passing rows at selected angles. Also in this case, the points of the jumper wires can be preheated using appropriate heating devices.

Insulating body A is penetrated by several rows of several straight jumper wires 8, 8 'each, located one above the other in the vertical direction at a mutual distance. The jumper wires 8, 8 ', with their both ends, abut on the respective longitudinal wires, Ь' of both mesh mats M, M ', and are slightly protruded from the sides of the protruding end E, E' beyond the longitudinal wires Ь, Ь 'to ensure reliable welding with appropriate longitudinal wires b, b 'mesh mats M, M'. As shown in FIG. 8 is an example of the construction element B, the jumper wires 8, 8 'are welded with the corresponding longitudinal wires b, b', and, as shown in FIG. 7b, all jumper wires 81, 81 'lie in common with a pair of longitudinal wires b1, b1' plane Ζ-Ζ, and the direction of the jumper wires 81, 81 'changes in a zigzag manner in the-Ζ plane, so that the arrangement of the jumper wires 81, 81 'like half-timbered. The corresponding angles of the jumper wires 81, 81 'relative to the longitudinal wires b1, b1' can be selected. At the building element B, standing on the edge B, several planes пров-Ζ of the jumper wires run horizontally at a distance parallel to each other,

those. jumper wire 8, 8 'form in the insulating body and, thus, also in the manufactured building element In the matrix structure, which gives the building element In the desired rigidity. The entry angle at which the jumper wires 8, 8 'are inserted into the gap between the two mesh mats M, M' can be adjusted by turning the device 6, 6 'to feed the jumper wires along the double arrow P13 (Fig. 6), the angles of both jumper wires 8, 8 'with respect to the mesh mats M, M' are chosen for the same value, but with a different sign to achieve the rigidity of the building element like half-timbered.

The material and construction of the insulating body must be such that the insulating bodies rigidly fix the jumper wires 8 during subsequent further transportation in the direction of P1 production in their position inside the insulating body Number and input angles of the jumper wires 8, 8 'in the-Ζ planes, as well as mutual the vertical gaps between the Ζ-Ζ planes are chosen in accordance with the static requirements for the building element B.

In some cases of application, it may be necessary to manufacture the insulating body of the building element B from such rigid materials so that it cannot be penetrated by the jumper wires 8, 8 'without deformation. Hard plastics, such as polyurethane, equipped with expanded or expandable polystyrene as a light additive, lightweight concrete, gypsum plasterboard or extruded cement-bonded plates, containing polymer waste, wood chips or wood chips, mineral or vegetable, can be used. fibrous materials. In these cases, in front of each device 6, 6 'for the supply of jumper wires, there is one piercing device 34, 34', which, as schematically depicted in FIG. 6, the corresponding channels C, C are arranged in the insulating body to accommodate one jumper wire 8, 8 'each.

Both mesh mats M, M 'using the second pair 18, 18' of the propulsive elements of the transport device 1 6 for the wire nets periodically and synchronously with the advanced chain conveyors 27, 27 'of the insulating body together with the jumper wires 8, 8' are fed to the connected devices 7 , 7 'for welding jumper wires, in which jumper wires 8, 8' at one end are welded with rotating wires M, M 'of the welding mats M, M' in the planes Ζ-Ζ of the welding tongs at one end. Welding tongs are made in the form of pairwise interacting, double-arm, swivel lower and upper arms facing the mats M, M ', turning in the plane of the jumper wires Ζ-мы whose ends contain at least one welding electrode for welding at least one jumper wire 8, 8 'with the longitudinal wire b, b' net mesh M, M '.

Device 7, 7 'for welding jumper wires are opposite to each other with displacement on the outer side of both mesh mats M, M' and mounted to move in the longitudinal direction and across the process channel 2. In the framework of the invention one after another, when viewed in the direction of P1 advancing mesh mats M, M ′, two or more devices 7, 7 ′ for welding jumper wires to each side surface may also be located.

The form-stable building element B is then periodically transported further using a transport device 35 connected in series, which contains mainly two pairs of transporting elements 36, 36 ', 37, 37' opposite to each other on both sides of the technological channel 2.

Ledges behind the mesh mats M, M 'the ends of the jumper wires 8, 8' create when manipulating the building element B a significant risk of injury, impede the stacking of the building elements for transportation and must therefore be separated so that the jumper wires 8, 8 'end up as can be more flush with the longitudinal wires b, b '. Using the first pair of transporting elements 36, 36 ', the building element B is fed to cutting devices 8, 8' connected in series and arranged offset on opposite sides of the technological channel 2, which cut protruding lateral wires behind the corresponding longitudinal wires M, L 'of the mesh mats M , M 'ends E, E' flush with the longitudinal wires b, b '. To improve the performance of the installation, in addition, in the framework of the invention, with each side surface of the trimmed building element B next to each other, when viewed in the direction of P1 production, several trimming devices 8, 8 'can be located.

The finished trimmed construction element B is removed by means of a second pair of transporting elements 37, 37 'of the transport device 35 from the technological channel 2 and transmitted to the transverse transport device 9 for withdrawing and stacking several construction elements B.

The distance between the second pair of feeding elements 18, 18 'of the transport device 16 for mesh mats and the first pair of transporting elements 36, 36' of the transport device 35 for building elements, as well as the distance between the pairs of transporting elements 36, 36 ', 37, 37' should be always less than the minimum length of the mesh mats M, M 'used to manufacture the building element B, in order to ensure reliable further transportation of the mesh mats M, M' between the transport devices 16, 35 and through them.

For the continuous manufacture of building elements B, reliable and uninterrupted supply of both wire mesh sheets C, O ', mesh mats M, M' and blade K of insulating material or separate insulating plates I to individual machining sections 5, 5 'is required; 6, 6 '; 7, 7 '; 8, 8 '; 9. To ensure this, the feed rolls 10, 10 'for wire mesh cloths, a pair of feed elements 17, 17', 18, 18 'for mesh mats of the transport device 16, a pair of transport elements 36, 36', 37, 37 'of the transport device 35 and chain conveyors 27, 27 'are driven by a central main feed drive 38, all elements 17, 17'; 18, 18 '; 36, 36 '; 37, 37 'and the feed rolls 10, 10' are interconnected by means of articulated drive shafts 39, 39 '(Fig. 2). Advance steps occur on a tactical basis, since the input of jumper wires 8, 8 ', welding of jumper wires 8, 8' with wires of mesh mats M, M 'and trimming of protruding ends E, E' of jumper wires occurs respectively when the mesh mats M, M 'stop, insulating body A or building element B. In this case, the length of the advancing steps is chosen in accordance with the pitch of the transverse wires or the integer multiple of the pitch of the transverse wires.

Due to the expansion of the technological channel 2 and the leading devices 15, 15 ', as well as the corresponding, carried out separately or jointly lateral displacement of the feeding elements 17, 17', 18, 18 ', transporting elements 36, 36', 37, 37 'and elements of the sections processing 5, 5 '; 6, 6 '; 7, 7 '; 8, 8 'across the production line X-X building elements B can be made of different, given width.

Using the transverse transport device 19, the finished building element B is discharged to the side of the production line X-X. Initially, the building element B is supplied along a production line X-X to the transverse conveyor 41 provided with an appropriately gripped transporting body 40. The transporting body 40 may consist, for example, of a working cylinder, the piston rod of which is mounted for movement along the double arrow P14.

The transverse conveyor 41 consists, for example, of two working cylinders whose piston rods are mounted for movement along the double arrow P16 and are equipped with each pushing plate 42. The transverse conveyor 41 pushes the finished building elements B along the arrow P15 from production line XX to schematically depicted tilting device 43, containing several crossbars 44 pivoting along the double arrow P17. Manufactured in the production plant on the edge building elements B using tilting mouth oystva 43 is brought into a horizontal position and are stacked T.

From the stack of grids 46, mesh mats M ′ are successively removed using a transport body 47 mounted to rotate along the double arrow P18. driven by a double arrow P20 feeding device 51, for example, the feeding roll. The retractor 49 consists, for example, of a working cylinder, the piston rod of which is mounted for movement along the double arrow P21 and provided with a gripper 52 for gripping the mesh mat M '. The correct device 50 contains an inlet guide 53 for the mesh mat M ′, which are somewhat arranged with two rows of training rollers 54 and eccentric rollers offset to each other. they are at a distance from each other and parallel to the web K of the insulating material and together with it with the help of pairs of transporting elements 17, 17 '; 18, 18 'are periodically supplied along production line XX to connected processing devices 6, 6'; 7, 7 '; 8, 8 '.

In the framework of the invention, instead of the wire mesh sheet C, it is possible to provide a second stack of prefabricated mesh mats M and feed the nets using the device 4 for feeding the wire mesh sheets.

Schematically shown in FIG. 3, the feed members 17, 18 of the transport device 16 for the mesh mats comprises a shaft 58 inclined to the vertical, driven through a coupling 59 by an angular gear 60 and mounted in a counter support 61. The angle gear 60 is driven through the drive shaft 39 by the main feed drive 38. Each shaft 58 is provided with several transporting disks 62 arranged at a mutually adjustable distance, which for adjustment are mounted on the shaft 58 for rotation, and after regulation are firmly connected to the shaft 58 by means of a clamping element 63.

The conveying discs 62 have, as shown in FIG. 4a, several evenly distributed circumferentially recesses 64 of a selectable depth for engaging the mats, so that flattened teeth 65 are formed. 'mesh mats M, M' transporting disks 62 and ensure the promotion of mesh mats M, M 'without slipping. Due to the inclined position of the shafts 58, the conveying disks 62 of each pair of pushing members 17, 17 '; 18, 18 'affect not only one, but also several transverse wires O. O' of the mesh mats M, M ', so that the tensile force is distributed over several wires and they are therefore not loaded when advancing the mesh mats M, M' too hard. The inclined position of the shafts 58 also provides continuous and without slippage further transportation of the mesh mats M, M 'of successive building elements B, while those following the mesh mats in the joint zone may have gaps arising, for example, when cutting pieces of wire mesh paintings C. O '.

Transporting elements 36, 36 '; 37, 37 'of the transport device 35 for building elements are made similarly to the feeding elements 17, 17'; 18, 18 'of the transport device 16 for mesh mats. Only those shown in FIG. 4b, the transporting discs 66 have notches 64 of lesser depth for engaging the mats. The feed rollers 10, 10 'for wire mesh cloths C. O' contain mainly the same elements as those shown in FIG. 3 feed elements 17.8 of the transport device 16 for mesh mats. The only difference is that the notches 64 for engaging the mats of the transporting discs 66 are significantly deeper, so that they have sharp teeth 67. This form of teeth 67 ensures that the non-directional wire mesh C entering the side C. With the teeth 67 securely grip the transverse wires O. O 'C. Wire Mesh Fabrics C. O' and without slippage promotes wire mesh cloth C. C. C '.

In the installation according to the invention, it is possible to manufacture building elements B in which the mesh mats M, M 'have a different construction, i.e. different pitch of longitudinal and / or transverse wires, as well as different diameters of longitudinal and / or transverse wires. Different pitch of the transverse wires should correspond, however, to an integer multiple and can be, for example, 50, 100 or 150 mm. A further limitation is the need to ensure that the jumper wire 8. 8 'can be positioned with the possibility of reliable welding with the longitudinal wires of both mesh mats M, M', despite this different pitch and wire diameter.

In the installation according to the invention, it is possible to manufacture building elements B in which one and / or both mesh mats M, M 'are issued as an insulating body on one or both sides parallel to the P1 production side. To achieve this, either the drivers 57 raise or extend, or the transport path of the chain conveyor 27 is raised so that the lower, parallel to the P1 production direction, the side surface of the insulating body is raised accordingly, due to which one and / or both mesh mats M, M 'form from this side, the desired protruding segment. The transport path located on the upper side of the insulating bodies of the upper chain conveyor 27 'must be respectively lowered or the leads 57' must be lowered or extended accordingly.

For the manufacture of building elements B, in which insulating bodies extend beyond both mesh mats M, M 'from one or both parallel to the P1 production side, the transport path of the upper chain conveyor 27' is raised so that the lower and, if necessary, upper the side surface of the insulating body parallel to the production direction P1 is respectively lowered or raised relative to the mesh mats M, M ', due to which the insulating body protrudes over both mesh mats M, M 'on one or both sides with desired protruding segments.

Continuous production of building elements B using the installation according to the invention occurs predominantly in such a way that the mesh mats M, M 'of successive building elements B are separated from each other only by a negligibly narrow dividing seam between the longitudinal wires of successive mesh mats M, M ', and, accordingly, the insulating bodies of the consecutive building elements B corresponding to them follow each other without noticeable gaps.

In the framework of the invention, however, construction elements B can be manufactured, in which one and / or both mesh mats M, M 'are issued as an insulating body on one or both sides perpendicular to the direction P1 of the production side. If one or both of the mesh mats M, M 'should

- 8 006403 to stand out for the insulating body V on both sides, the insulating bodies V of the adjacent building elements B are fed to the technological channel 2 by a belt conveyor 22 with appropriately selected gaps and advanced there with these predetermined gaps. When using an endless web of insulating material, when separating insulating bodies V, it is necessary to cut a piece corresponding to this gap out of the web of insulating material. The two dividing seams between the mesh mats M, M 'of the successive building elements B are either directly facing each other or displaced laterally relative to each other.

For the manufacture of building elements B, in which both mesh mats M, M 'are issued as insulating bodies V with one or both of the sides passing perpendicular to direction P1, mesh mats M, M' are advanced in the technological channel 2 with a predetermined interval. To obtain this selectable gap between the mesh mats M, M 'of successive building elements B with the help of cutting devices 5, 5' while forming the mesh mats M, M ', the piece corresponding to this gap is cut out of the endless wire mesh sheets O, O'. The size of the gap is limited by the fact that it is necessary to guarantee the possibility of overlapping gaps between the mesh mats M, M 'of successive building elements In the spacing shafts 58 of the transport device 16 for mesh mats and the transport device 35 for building elements, so as to ensure the movement of the mesh elements without slipping mats M, M 'successive building elements B.

FIG. 5a shows a schematic representation of a device for cutting mesh mats 5, 5 ′, which makes a separating section and thereby continuously separates the mesh mats M, M ′ from the wire mesh sheet O of the grid. Depicted in FIG. 5a, the device 5 for cutting mesh mats comprises a cutting bar 68, which, when a wire mesh cloth O is standing on an edge, passes in a vertical direction parallel to the wire mesh cloth O and is located on one side of the latter. On the other hand, the wire mesh cloth O is located also passing vertically, parallel to the wire mesh cloth O, the blade bar 69. The cutting 68 and knife blade 69 bars are installed with the possibility of supplying and withdrawing from the wire mesh cloth O and correspondingly from the double arrow P23 and P24, respectively. For cutting the wire mesh cloth O, the cutting bar 68 carries the counter knife 70. The blade bar 69 carries the cutting knife 71, which, when cut, interacts with the opposite counter knife 70. In FIG. 5a, the counter knife 70 is already shown in its cutting position, while the cutting knife 71 is in motion towards the wire mesh sheet O. Cutting 68 and knife bar 69 are adjustable for positioning and advancing against the wire mesh in the direction P3. In the framework of the invention, instead of one mating and one cutting knives, several mating and cutting knives can be used in order to cut each longitudinal wire L of the wire mesh fabric separately or in groups.

FIG. 5b depicts another exemplary embodiment of the device 5, 5 'for cutting mesh mats, which provides cutting from the wire mesh fabric O in the process of cutting a selectable piece, the length of which in the forward direction P3 corresponds mainly to the distance between adjacent transverse wires, the so-called transverse wire step, or integer a multiple of the pitch of the transverse wires, and at the same time the ends of the longitudinal wires are trimmed. The depicted device for cutting wire nets contains a cutting bar 72, which, when a wire mesh cloth O is standing on an edge, passes in a vertical direction parallel to the wire mesh cloth O and is located on one side of the latter. On the other hand, the wire mesh cloth O is also located vertically, parallel to the wire mesh cloth O, the blade bar 73. The cutting 72 and knife blade 73 bars are installed with the possibility of supplying and discharging the wire mesh cloth O and away from it, respectively, by the double arrow P23 and P24. To cut a piece of wire mesh cloth O, the cutting bar 72 carries two positionally adjustable transverse wires O of the wire mesh cloth O of the counter knife 74, and, moreover, the mutual distance between the two counter blades 74 can be adjusted by the length of the cut piece. The blade bar 73 carries two positionally adjustable transverse wires O of the wire mesh fabric O of the cutting knives 75, the mutual distance between which can be adjusted by the length of the cut-out piece, and which interacts with the opposite counter-knife 75 when cutting the piece. FIG. 5b, the counter knives 74 are already shown in their cutting position, while the cutting knives 71 are still in motion to the wire mesh sheet O. The cutting 72 and knife 73 bars are adjustable for positioning and facing towards the wire mesh in the direction P3. In the framework of the invention, in this exemplary embodiment, instead of one return and one cutting knife, several response and cutting knives can be used in order to cut pieces for each longitudinal wire B of the wire mesh sheet O separately or in groups.

Schematically shown in FIG. 6, the device 6 for feeding the jumper wires comprises a base 76 carrying a backstop 77, extending in the direction of the building element 8 a guide 78 and a cutting device 79. On the guide 78, it can be moved along

- 9 006403 double arrow P25 with the help of a driving device (not shown), for example, a working cylinder, a crank mechanism, an electric drive, etc., are fitted with a slide 80. On the slide 80 are arranged to feed the jumper wire 8 wire Ό vertical exhaust wire forming the jumper wire 8 bar 81 with acting as a device for feeding the wire pushing clamp 82 and protruding sideways adjustment tire 83.

The pushing clamp 82 contains two wedge-shaped, firmly connected to the exhaust beam 81, exhaust pads 84, two interacting with the exhaust pads 84, movable wedge-shaped clamping pads 85 and spring 86, which presses the clamping pads 85 to the exhaust pads 84. Located on the base 76 of the reverse stopper 77 made similar to the pushing clamp 82 and contains two wedge-shaped, firmly connected to the base 76 of the lock pads 87, two interacting with the lock pads 87, movable wedge-shaped clamping pads 88 and p a gun 89 clamping the clamping pads 88 to the locking pads 87. At the protruding end of the adjusting tire 83 there is a vertical piercing bar 90, which can be moved along the double arrow P26 by means of driving means (not shown), for example, a working cylinder, a driving screw, etc. p., and fixation on the adjusting tire 83. At least one piercing needle 91 is placed on the piercing bar 90 in such a way that, with its free protruding end, it runs in the direction of the building element B perpendicular the adjustment bus 83 and perpendicular to the piercing bar 90. The cross section of the piercing needle 91 is predominantly round, the diameter of the piercing needle 91 being at least equal to the diameter of the jumper wire 8 passing through the insulating body, but preferably greater than the diameter of the jumper wire 8. At its free end the piercing needle 91 is provided with a wear-resistant, preferably hardened, tip 92.

The described device 6 for filing jumper wires works as follows. Due to the feed movement of the slide 80 in the direction facing the double arrow P25, the piercing needle 91 moves towards the building element B. In this case, the tip 92 penetrates into the insulating body Y and forms the receiving channel C during the feed movement.

The feed motion of the slide 80 ends when the point 92 penetrates the insulating body U completely and exits the insulating body U on the opposite side. or, similarly to a soldering iron, by means of a heating cartridge.

Simultaneously with the movement of the supply of the piercing needle 91 in the direction of the double arrow P25, the wire Ό due to the movement of the supply of the slide 80 is unwound using the push-in clamp 82 from the reel 32 (not shown) through the edging 93 and horizontal 93 'straightening direction training device 33 and along the arrow P12 moves along the entry line formed by the exhaust pads 84 and due to the movement of their supply. Due to the movement of the feed of the slide 80 and, thereby, of the pushing clamp 82 in the direction of the building element B, the clamping pads 85 due to the wedge-shaped execution of the exhaust pads 84 accommodating them, in addition to the action of the spring 86, are pressed against the jumper wire 8 and are gripped. To enhance the frictional circuit with a jumper wire 8, the clamping pads 85 on their side facing the jumper wire 8 are additionally provided with teeth.

At the same time, the jumper wire 8 advances the clamping pads 88 of the return stopper 77 to its spring 89 and to the wider end of the wedge-shaped opening of the brake pads 87, so that the brake pads 87 do not have any resistance to the movement of the jumper wire 8. Jumper wire 8 through coinciding with the input line of the cutting nozzle 94 of the cutting device 79 is passed through the receiving channel C, formed in the insulating body I for the previous working time using the piercing needle 91. The feed movement of the jumper wire 8 continues until the start of the jumper wire 8 will not protrude beyond the plane of the mesh mat M and due to this, in the next operation it will not be welded with the corresponding wires b and O of the mesh mat M.

The length of the supply path piercing needle 91 and jumper wire 8 exactly the same. At the end of the feed movement, the jumper wire 8 is separated from the wire Ό by means of the cutting knife 95 of the cutting device 79. The slide 80 returns to its original position, the piercing needle 91 is removed from the receiving channel C, and the clamping shoes 85 of the advance clamp 82 release the wire Ό, whereas clamping pads 88 of backstop 77 hold the wire Ό in its position and prevent it from retracting back in the direction of the roll 32.

In the framework of the invention, it is also possible to remove the already cut, straightened jumper wire 8 from the magazine and enter the preformed receiving channel C along the insertion line into the preformed receiving channel C using the feeding device 6. In this case, the training device 33, the reverse stop 77 and the cutting device 79 do not function.

The base 76 is rotatably mounted at point 96 along the double arrow P13, so that any angles between the jumper wires 8 and the piercing needle 91 can be adjusted, on the one hand, and the longitudinal wires b, b 'mesh mats M, M', on the other parties.

In the manufacture of building elements B, the jumper wires 8, 8 'in most cases are supplied from both opposite sides of the building element B, so that on each side of the building element B have one feeding device 6, 6'. FIG. 6, for clarity, only the second piercing needle 97 and the additional jumper wire 8 'are shown. The piercing needle 97 moves along the double arrow P27, while the jumper wire 8 'moves along the arrow P12'. The movement of the piercing needle 97 in the direction of the building element B and the passage of the jumper wire 8 'through the insulating body occur simultaneously and together.

The piercing needle 97 and the jumper wire 8 are presented at the time of their respective feed motion, shortly before they reach their final position.

For simultaneous supply of several jumper wires 8 on the working stroke on the exhaust bar 81 in the planes Ζ-Ζ of the jumper wires one above the other with selectable gaps there are several advance clamps 82, and on the base 76 stationary one above the other in respective positions there are several associated stoppers 77 reverse and cutting devices 79. For the formation of the corresponding receiving channels C on the piercing bar 90 in the respective planes Ζ-Ζ of jumper wires one above the other, Several piercing needles 91 are laid. Each piercing needle 91 lies along with an insertion line of a corresponding pushing clamp 82, a corresponding cutting nozzle 94 and a corresponding backstop 77 in the horizontal plane Ζ-Ζ of jumper wires (Fig. 7b). When inserting the pre-cut jumper wires into the receiving channel C, each piercing needle 91 lies along with the corresponding input device also in the corresponding horizontal plane Ζ-Ζ of the jumper wires. For the purpose of fitting to different thicknesses of the insulating body, all of the piercing needles 91 can be jointly advanced in the longitudinal direction by means of a driving device (not shown), for example, a lead screw, a driving chain, etc. and are fixed in the piercing bar 90 in their working position by means of a clamping device, for example with a clamping screw.

For the simultaneous supply of several jumper wires 8 'to the working cycle on the other side of the technological channel 2 in the planes Ζ-Ζ one above the other have corresponding devices.

The tools for forming the receiving channel for the jumper wires 8, 8 'can be made in the form of massive pins or hollow needles or in the form of rotating drills and have a wear-resistant, for example, hardened, point. Pins or hollow needles are made, preferably, with the possibility of pre-heating their tips to facilitate penetration of the insulating body.

In the framework of the invention, it is possible to make a piercing needle in the form of a hollow needle and fix it on the pushing clamp 82 coaxially with the jumper wire 8, 8 'along the line of its insertion. The inner diameter of the cannula is just such a size that the jumper wire 8, 8 'can be passed through it. Due to this arrangement, the cannula and the jumper wire 8, 8 'move simultaneously and coaxially due to the movement of the feed of the pushing clamp 82, and the cannula forms the receiving channel C simultaneously with the advance of the jumper wire 8, 8'. In this exemplary embodiment, the cannula must first be retracted to its original position with the help of the pushing clamp 82, before the jumper wire 8, 8 'inserted into the insulating body can be separated from the stock of the wire with the help of the cutting device 70.

Schematically shown in FIG. 7a, the trimming device 8 comprises a cutting bar 98 that is rotatably mounted on the double arrow P2 8 and extends parallel to the mesh mats M, M 'of the building element B and carries several upper blades 99, each of which is located in the zone of the Ζ-plane of the jumper wires. In the depicted examples, the mesh mats M, M 'of the building element B are located on the edge, so that in FIG. 7a, the plane Ζ-Ζ of the jumper wires coincides with the plane of the drawing, and the cutting bar 98 extends vertically. The cutter 8 contains, in addition, mounted with the possibility of rotation along the double arrow P29 knife bar 1 00, which runs parallel to the mesh mats M, M 'of the building element B and carries several lower blades 1 01, each of which is located in the zone of the plane Ζ-Ζ jumper wires.

Each upper knife 99, as shown in FIG. 7a, 7b, 7c, has two notches 102 for two transverse wires O of the mesh mat M, so that it becomes possible to turn the upper knives 99 freely through the transverse wires into their working position between the longitudinal wires L of the mesh mat M. 02 They are selected in accordance with the pitch of the transverse wires of the mesh mats M. Each upper knife 99 has, in addition, two fishing socks 103, which are equipped with a triangular guide-centering recess 104 for the longitudinal wires b on their underside.

- 11 006403

Each lower knife 101 has two deflecting socks 105, which, when turning the lower knives 101 to the cutting position, prevent the lower knives 101 from penetrating under the longitudinal wires L of the mesh mats M and are entangled there. Between the two deflecting socks 105 there is a cutting edge 106 for separating the protruding end E of the jumper wire. The upper 99 and lower 101 knives consist of a hardened material, and the sides of the cutting edge 106 are further polished.

Cutting device 8 operates as follows. FIG. 7b, the upper 99 and lower 101 knives are in their initial position outside the building element B. With the help of reversible rotary devices, the cutting bar 98 and, thus, also all the upper knives 99 are rotated together from their initial position in FIG. 7b in the corresponding direction of the double arrow P28 to the building element B to the centering position in FIG. 7c. In this case the fishing socks 103 enter between the wires b1; About the mesh mat M in such a way that the longitudinal wire L1, to which the cut off jumper wire 81 is welded, is fixed in the guide-centering grooves 104 of the catching socks 103 of the upper knife 99. The guide-centering grooves 104 are designed in such a way that the longitudinal wire L1 when turning the upper knives 99 is reliably caught and guided, and the upper knife 99 by fixing the longitudinal wire b1 forms a support for it. The transverse wires O. do not interfere with the rotation of the upper knives 99 because they find enough free space in the notches 102 of the upper knife 99 (Fig. 7). The lower knife 101 remains in its original position.

By means of respectively reversible turning devices, the blade bar 1 00 and, thus, all the lower knives 101, guided by the deflecting socks 105, are rotated together in the next working step from their original position in FIG. 7b in accordance with the direction of the double-arrow P29 towards the cutting position in FIG. 7c. When this cutting edge 1 06 adjacent to the detachable protruding end E of the jumper wire.

Shown in FIG. 7c, the cutting position does not mean, however, interruption of the process P29 of the movement of the blade bar 1 00, but is only an instantaneous representation of the process of movement. The lower blade 1 01 moves further in the corresponding direction of the double arrow P29 towards the building element B and at the same time separates the protruding end E of the jumper wire. After separation of the protruding end E of the jumper wire, the cutting bar 98 with all the upper blades 99 and the blade bar 1 00 with all the lower blades 1 01 fold back to their original positions. The now cut off building element B is then advanced horizontally in the direction P1 of production, so that the other gaps of the uncircumcised jumper wires fall within the range of the cutter 8.

The cutting device 8 'is made similar to the cutting device 8 and synchronously with the cutting device 8 separates the other protruding end E' of the jumper wire.

Depicted in FIG. 8 in a perspective view, the building element B consists of the outer M and the inner M ′ of the mesh mats, located at a predetermined distance parallel to each other. Each mesh mat M, M 'consists of several longitudinal b, b' and transverse O. O 'wires, which intersect and are welded together at the intersection points. The mutual distance between the longitudinal b, b 'and transverse O. O' wires is chosen in accordance with the static requirements for the building element B. The distances are chosen mostly equal, for example, in the range of 50-150 mm, so that respectively the adjacent longitudinal and transverse wires form square cells . In the framework of the invention, the cells of the mesh mats M, M 'may also be rectangular and have, for example, a short side face 50 mm long and a long side side 75-100 mm long.

The diameters of the longitudinal b, b 'and transverse O. O' wires are also chosen in accordance with static requirements, and they lie mainly in the range of 2-6 mm. Wire surface b, b '; A. O 'of the mesh mats M, M' may be smooth or ribbed in the framework of the invention.

Both mesh mats M, M 'are interconnected by several jumper wires 8, 8' into a form-stable lattice body A. Jumper wires 8, 8 'are welded at their ends, respectively, with wires of both mesh mats M, M', and in the framework of the invention the jumper wires 8, 8 'are welded either, as shown in FIG. 8, with corresponding longitudinal b, b ', or with transverse O, O' wires. The jumper wires 8, 8 'are alternatively arranged in an opposite direction at an angle, i.e. like the half-timbered frame, thanks to which the lattice body A is stiffened against the shear load.

The gaps between the jumper wires 8, 8 'and their distribution in the building element B depend on the static requirements for the building element and are, for example, 200 mm along the longitudinal wires, and 1 00 mm along the transverse wires. Mutual gaps between the jumper wires 8, 8 'in the direction of the longitudinal b, b' and transverse O, O 'wires make up expediently a multiple of the pitch of cells. The diameter of the longitudinal b, b 'and transverse O, O' wires lies mainly in the range of 3-7 mm, and for building elements with thin longitudinal and transverse wires, the diameter of the jumper wires 8, 8 'is preferably chosen larger than the diameter of the longitudinal and transverse wires.

- 12 006403

Formed from both mesh mats M, M 'and jumper wires 8, 8', the spatial lattice body A must not only be form-stable, but also be used as a wall element and / or floor element in its preferred use as a reinforcing element, t. e. perceive shear and compressive forces. Therefore, the longitudinal and transverse wires are welded to each other, as is usual for reinforcing meshes, and the jumper wires 8, 8 'with wires b, b; O. O 'mesh mats M, M' with the observance of the minimum strength of welded nodes. To perform the function of spatial reinforcement element of wire b, b '; O. O 'mesh mats M, M' and jumper wires 8, 8 'should consist of suitable materials and have the appropriate values of mechanical strength so that they can be used respectively as reinforcement wires for mesh mats M, M' used as a reinforcing mesh, and as a reinforcing wire connecting the two mesh mat M, M '.

In the gap between the mesh mats M, M 'at a given distance from them, there is an insulating body V, the outer surfaces of which run parallel to the mesh mats M, M'. Insulating body V is used for heat and sound insulation and consists, for example, of foams, such as polystyrene foam or polyurethane foam, rubber and rubber-based foams, lightweight concrete, such as autoclaved or aerated concrete, porous plastics, porous materials on rubber and rubber, pressed slag, plasterboard, pressed cement cement binder, consisting of wood chips, jute, hemp and sisal fibers, rice husk, straw waste, mineral and glass wool, corrugated cardboard, ressovannoy wastepaper associated brick rubble and molten, recyclable plastic waste. The insulating body V may, in the framework of the invention, also consist of bioplastics, for example, of an algal foam material made from foamed algae or algal cellulose.

The insulating body V can be provided with pre-drilled holes to accommodate the jumper wires 8, 8 '. The insulating body V 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 V in the building element B is fixed by means of angled jumper wires 8, 8 ', penetrating the insulating body V.

The thickness of the insulating body V can be freely selected, and it lies, for example, in the range of 20,200 mm. The intervals between the insulating body V and the mesh mats M, M 'can also be freely selected, and they lie, for example, in the range of 10-30 mm. The building element B can be made of arbitrary length and width, and on the basis of the manufacturing method, the minimum length of 100 cm and the standard width of 60, 100, 110 and 120 cm were preferred.
