The front ends of the jumper wires are welded with the corresponding wire mesh of one wire mesh fabric and the jumper wires are separated from the supply of wire. In a subsequent operation in another device for welding jumper wires, the separated ends of the jumper wires are welded with the corresponding wire mesh of another wire mesh cloth.

The apparatus according to the invention depicted in FIG. 1 is used for the manufacture of the construction element B shown in FIG. 8, consisting of two parallel flat mesh mats M, M ′ of intersecting and welded together at the intersection points of longitudinal L, L 'and transverse Q, Q 'wires from the holding mesh mats M, M' at a given mutual distance of the direct jumper wires S, S ', which are welded at one end to one wire of both mesh mats M, M', as well as from located between the mesh mats M, M ' on a given m distance from them, at least partially dimensionally stable insulating body W, for example an insulating plate from plastic.

The installation depicted in Fig. 1 comprises a main frame 1, on which preferably only a schematically horizontal, defining the production line ХX Х technological channel 2 is located in the middle. At the input of the technological channel 2 there is a device 3 for supplying an insulating body W. On both sides of the technological channel 2, if you look in the production direction P1, there is one device 4, 4 'for feeding wire mesh cloths, one device 5, 5' for cutting mesh mats, one device for each count 6, 6 'for supplying the jumper wires of one device 7, 7' for welding the jumper wires and one edging apparatus 8, 8 '. At the exit of the technological channel 2, in addition, a transverse transport device 9 for building elements.

Using a feed device, for example a feed roll 10, 10 'in a double arrow P2, P2', feed devices 4, 4 'for feeding wire mesh webs, from two rolls 11, 11' along the arrows P3, P3 'unwind two standing on the edge of the wire mesh cloths G, G ', and the mutual distance between the longitudinal L, L' and the transverse Q, Q 'wires of each wire mesh cloth G, G', i.e. the so-called pitch of longitudinal and transverse wires, as well as the width of each wire mesh cloth G, G ’, can be freely selected within certain limits. Each device 4, 4 'for feeding wire mesh cloth contains a correct device 12, 12', which corrects the corresponding wire mesh cloth G, G 'and consists of several regular rows 13, 13' located in two rows offset from each other ( figure 2) and supplied eccentric rolls 14 (figure 2). The feed rolls 10, 10 'have the task of periodically feeding the wire mesh cloths G, G' for further processing to sequentially connected devices 5, 5 'for cutting the mesh mats in the direction of the arrows P3, P3' or at the end of the production of removing any more residual wire mesh cloths G , G 'in the direction opposite the arrows P3, P3' from the straightening 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 web G, G’ and the initial position in which it is out of contact with the wire mesh web G, G ’.

The devices 5, 5 ’for cutting mesh mats, as described using FIGS. 5a, 5b, are separated from the endless wire mesh cloths G, G’, respectively, mesh mats M, M ’of a given length. Due to slightly curved, only elastically deforming mesh mats M, M 'and ending tangentially on opposite longitudinal sides of the technological channel 2 of the driving devices 15, 15' (figure 2), which consist, for example, of several arcuate strips located one above the other 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 so that there they fall into position parallel to each other at a mutual distance corresponding to the desired thickness to the fabricated building element B. In the technological channel 2, both mesh mats M, M 'with the help of spacing holding elements, consisting, for example, of spacing plates and several spacing rails located vertically one above the other, are reliably guided over their entire width and always precisely held at this specific distance.

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

The device 3 for supplying insulating material shown in FIG. 2 is used to supply insulating plates I, to interconnect them in the web K of insulating material and to separate the insulating body W from the web K of insulating material. The device 3 for supplying insulating material contains a retracting device 19, which feeds from the side insulating plates I intended to form the insulating body W of the building element B in the direction of arrow P4 to the production line XX of the installation. The retractor device 19 consists mainly of two working cylinders 20, the piston rods of which are mounted for movement along the double arrow P5 and are equipped with a pressure plate 21 at their end. In the production line XX there is a conveyor belt 22 driven by a drive 23 conveyor in the production direction P1 and feeding the insulating plate I in this direction along the production line XX. Using the transversely movable thrust frame 24, the movement P4 of the supply of insulating plates I is limited and the position of the insulating plates I in the production line XX is precisely set. On the input side of the conveyor belt 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 equipped with a pressure plate corresponding to the end surface of the insulating plate I. Using the feeding device 25, the insulating plate I 'located on the conveyor belt 22 is further advanced in the direction of arrow P1 so as to move the insulating plate I' relative to the already formed insulating material web K, thereby connecting the insulating plate I 'with a geometric and force closure with the end of the web K of insulating material and form an infinite single web K of insulating material. The connection with a geometric circuit is understood to mean the connection of insulating plates I, I ’, which at the junction of both insulating plates I, I’ has neither gaps, nor lateral overlaps. Connection with power circuit means the connection of insulating plates I, I ’, in which the connection does not diverge under the influence of tensile and compressive loads.

To connect the insulating plates I 'with the already formed sheet K of insulating material in the output zone of the conveyor belt 22, a connecting device 26 is located. The connecting device 26 is arranged to move along the double arrow P7 across the production line XX and along the double arrow P8 parallel to the production line X -X. According to this exemplary embodiment, insulating plates I, I 'are used having flat end surfaces F on their narrow sides. To form an endless web K of insulating material, the insulating plate I', for example by heat sealing using a connecting device 26 made in the form of a heating device, is connected to cloth K of insulating material. The heating device consists mainly of a heating plate and used to heat the heating plate of a heating transformer.

The endless web K of insulating material is created as follows. The insulating plate I ’located on the conveyor belt 22 is advanced using the feeding device 25 in the direction of arrow P6 until the insulating plate I’ abuts against the heating plate adjacent to the end face of the sheet K of insulating material. Then, the heating plate is heated using a heating transformer until the adjacent end surfaces of the sheet K of the insulating material and the insulating plate I ’are softened. After that, 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 insulating material, and the insulating plate I' with the feeding device 25 is slightly advanced in accordance with the direction of production P6 so as to press the heated end surfaces to each other and, thereby, weld the insulating plate I 'with the sheet K of insulating material and, therefore, connect with a geometric and power circuit. Since the sheet K of insulating material during the connection process is periodically transported further along the conveyor belt 22 to the beat of the entire production unit in the production direction P1, the connecting device 26 also periodically moves in the corresponding direction of the double arrow P8 during heating, and after removing the heating plate in the corresponding opposite direction double arrow P8 returns back to its original position.

According to another embodiment, for forming an endless web K of insulating material, the insulating plate I ’is connected to the web K of insulating material by gluing using the connecting device 26, made in the form of a gluing device. The gluing device comprises, for example, a nozzle and a reservoir filled with suitable glue. The adhesive must be suitable for bonding the material of the insulating boards I, I ’and have a drying time consistent with the production speed to ensure reliable bonding of the insulating board I’ with the sheet K of insulating material. The bonding device is movable in horizontal and vertical directions to spray glue on the end surface F of the insulating plate I ’. In order to accelerate the application of glue, several gluing devices can also be used simultaneously in the framework of the invention. Within the scope of the invention, it is also possible to spray glue simultaneously on several I ’insulating boards. The endless web K of insulating material is created in this embodiment as follows. Immediately prior to supplying the insulating board I ’to the production line XX, the end surface F of the insulating board I is provided with glue. The insulating plate I 'with the help of the retractor 19 is first pushed sideways along arrow P4 into the production line XX and laid on the conveyor belt 22. Then, the insulating plate I' using the feeding device 25 is slightly advanced in the production direction P1 so that it is provided with glue press the end surface F of the insulating plate I 'to the end end surface of the sheet K of insulating material and thereby connect the insulating plate I' to the sheet K of insulating material with a geometric and force closure.

In the framework of the invention, the insulating plates I, I 'can have a groove on one end surface F, and a ridge on the other opposite end surface F', and the groove and comb are made so that the crest of one insulating plate I is geometrically and force-locked to the groove of the next insulating plate I '. Due to the relative movement along arrow P6, the crest of the insulating plate I ’fits into the groove of the end element of the already formed web K of insulating material. The grooves and ridges are coordinated with each other in their implementation with the possibility of forming a clamping connection with a geometric and power short circuit, which ensures both the alignment of the connected insulating plates I, I ’, and their strong connection between each other. The connecting device 26 in this embodiment is not valid.

In the framework of the invention, the end surfaces F of the insulating plates I, I ’provided with a groove and a crest can be additionally provided with glue to ensure a reliable connection of the insulating plates. In the context of the invention, the end surfaces of the insulating plates I, I ’adjacent to the formation of the insulating material web K can also be provided with other clamping and connecting elements made, for example, in the form of a dovetail, interacting with a geometric and force closure.

It is clear that the illustrated exemplary embodiments within the framework of the general idea of the invention can be modified in different ways, in particular with respect to the construction of devices for connecting the insulating plates I, I ’to form an endless web K of insulating material. When using appropriate adhesives, both the end surface F of the insulating plate I, I ’and the end end surface of the sheet K of insulating material can be provided with glue.

In addition, it is within the scope of the invention to provide one or both of the joined flat end surfaces F of the insulating boards I, I ’with a self-adhesive film. The film can be placed already in the manufacture of insulating plates I, I ’and it is advisable to protect the detachable film.

A conveyor device passing along the entire production line XX is adjacent to the belt conveyor 22, for example, a chain conveyor 27 driven in the production direction P1 and a moving fabric K of insulating material and insulating bodies W in the production line XX in the production direction P1.

The device 3 for supplying insulating material comprises a device 28 for cutting a sheet of insulating material, moved along the double arrow P9 across the production line XX and along the double arrow P10 parallel to the production line XX. The cutting device 28 separates an insulating body W of a selectable length from the sheet K of insulating material and contains at least one dividing disk 30 driven by the cutting drive 29. To increase the cutting performance, an additional cutting drive 29 ′ can be used together with the dividing disk 30. The cutting device 28 when cutting, it moves synchronously with the direction of movement of the chain conveyor 27 in the production direction P1 and after the cut is completed, it returns to its original position, and these movements occur along double arrow P10. Entering the cutting position and the corresponding conclusion from the cutting position occur in the double arrow P10.

Within the scope of the invention, other cutting methods and cutting devices can be used to separate the insulating body W from the web K of insulating material. These methods and devices should be consistent with the properties of insulating materials and ensure that the cut 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, as an apparatus for cutting a web of insulating material, an insulating material moved across the web K of insulating material and a cutting wire heated by a heating transformer can be used.

Since the cutting device 28, when cutting the web K of insulating material, is transported further by the chain conveyor 27 periodically to the whole production unit in the production direction P1, the cutting device 28 also periodically moves in the corresponding direction of the double arrow P10 during cutting and returns to its original position after cutting in the corresponding opposite direction of the double arrow P10. The chain conveyor 27 transports the insulating bodies W separated from the sheet K of insulating material in the production direction P1 to subsequent processing units of the installation.

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

It is also possible within the scope of the invention to provide additional clamping elements acting on the insulating material web K, which, when the insulating plate I ’is connected to the already formed insulating material web K, additionally fixes them.

On both sides of the technological channel 2 after the leading devices 15, 15 'there is one device 6, 6' for feeding jumper wires, with the help of which simultaneously on both sides of the technological channel 2 periodically from the bobbins 32, 32 'with a supply of wire according to the arrows P12, P12 'unwind several wires D, D', by means of a training device 33, straighten them out, insert them horizontally between the two mesh mats M, M ', pierce them as a nail through the insulating body W and separate them from the supply of wire. The penetration of the insulating body W is substantially facilitated by heating the tips of the jumper wires S, S ’, and heating, for example, occurs by means of an inductive heating device.

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

In the framework of the invention, pre-cut jumper wires S, S ’can be fed from the side of the process channel 2 to the mesh mats M, M’ in vertically extending rows at selectable angles. Also in this case, the points of the jumper wires can be preheated using appropriate heating devices.

The insulating body W is pierced by several rows of several straight jumper wires S, S ’in each, located one above the other in the vertical direction at a mutual distance. The jumper wires S, S 'with their both ends adjoin the respective longitudinal wires L, L' of both mesh mats M, M 'and slightly protrude protruding end E, E' from the sides for the longitudinal wires L, L 'to ensure reliable welding with the corresponding longitudinal wires L, L 'of mesh mats M, M'. As shown in FIG. 8, an exemplary embodiment of the building element B, the jumper wires S, S 'are welded with the corresponding longitudinal wires L, L', and, as shown in Fig. 7b, all the jumper wires S1, S1 'are in common with a pair longitudinal wires L1, L1 'of the ZZ plane, and the direction of the jumper wires S1, S1' zigzags in the ZZ plane, so that there is an arrangement of jumper wires S1, S1 'like half-timbered. The corresponding angles of the jumper wires S1, S1 ’relative to the longitudinal wires L1, L1’ can be selected. At a building element B standing on the edge, several Z-Z planes of the jumper wires extend horizontally at a distance parallel to each other, i.e. the jumper wires S, S ’form a matrix structure in the insulating body W and, therefore, also in the fabricated building element B, which gives the building element B the required rigidity. The angle of entry, at which the jumper wires S, S 'are introduced between the two mesh mats M, M', can be adjusted by turning the device 6, 6 'for feeding the jumper wires along the double arrow P13 (Fig.6), and the angles of both the jumper wires S, S 'with respect to the mesh mats M, M' are chosen to be identical in value, however, with a different sign to achieve the rigidity of the building element like half-timbered.

The material and design of the insulating body W must be such that the insulating bodies W rigidly fix the jumper wires S during subsequent further transportation in the production direction P1 in their position inside the insulating body W. The number and angles of entry of the jumper wires S, S 'in the ZZ planes, and also, the mutual vertical gaps between the ZZ planes are selected in accordance with the static requirements for building element B.

In some applications, it may be necessary to fabricate the insulating body W of the building element B from such rigid materials that it cannot be penetrated by jumper wires S, S ’without deformation. In this case, for example, rigid plastics such as polyurethane equipped with expanded or expandable polystyrene, lightweight concrete, gypsum boards or pressed cement-cement boards containing polymer waste, wood chips or wood chips, mineral or vegetable, can be used as light additives fibrous materials. In these cases, one piercing device 34, 34 'is installed in front of each device 6, 6' for supplying jumper wires, which, as shown schematically in Fig. 6, carry out corresponding channels C, C 'in the insulating body W to accommodate one jumper wire S, S 'in each.

Both mesh mats M, M ', using the second pair of 18, 18' advance elements of the wire mesh transport device 16, periodically and synchronously with the advanced chain conveyors 27, 27 'insulating body W together with the jumper wires S, S' are fed to the connected devices 7 , 7 'for welding jumper wires in which the jumper wires S, S' at one end are welded with pairs of welding tongs rotated in the ZZ planes with longitudinal wires L, L 'of mesh mats M, M'. The welding tongs are made in the form of pairwise interacting, two-shouldered, rotary lower and upper arms, facing the mesh mats M, M ', rotated in the ZZ plane of the jumper wires, the ends of which contain at least one welding electrode for welding at least one jumper wire S, S 'with a longitudinal wire L, L' of a mesh mat M, M '.

Devices for welding jumper wires 7, 7 'are opposite to each other with offset on the outer side of both mesh mats M, M' and are mounted with the possibility of movement in the longitudinal direction and across the technological channel 2. Within the framework of the invention, one after another, if you look in the direction P1 advancing mesh mats M, M ', two or more devices 7, 7' for welding jumper wires on each side surface may also be located.

The shape-resistant building element B is periodically transported further by means of a transport device 35 connected in series, which mainly contains two pairs of conveying elements 36, 36 ’, 37, 37’ opposite each other on both sides of the process channel 2.

The ends of the jumper wires S, S 'protruding from the sides of the mesh mats M, M' when handling the building element B pose a significant risk of injury, prevent the stacking of building elements for transportation and must therefore be separated so that the jumper wires S, S 'end as can be flush with the longitudinal wires L, L '. Using the first pair of conveying elements 36, 36 ', the building element B is fed to the trimming devices 8, 8' connected in series and located on the opposite sides of the process channel 2, which cut the mesh mats M protruding from the sides for the corresponding longitudinal wires L, L ' , M 'ends E, E' flush with the longitudinal wires L, L '. In order to increase the productivity of the installation, in addition, within the framework of the invention, one after the other, when viewed in the production direction P1, several trimming devices 8, 8 ’can be arranged on each side surface of the cut-off building element B.

The finished cut-off building element B is brought out by means of a second pair of conveying elements 37, 37 ’of the transport device 35 from the technological channel 2 and transferred to the transverse transport device 9 for removal and stacking of several building elements B.

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

For the continuous production of building elements B, a reliable and uninterrupted supply of both wire mesh cloths G, G ’, mesh mats M, M’ and cloth K of insulating material or individual insulating plates I to individual processing 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 of which are 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). The steps of moving forward are tactful, since the insertion of the jumper wires S, S ', the welding of the jumper wires S, S' with the wires of the mesh mats M, M 'and the trimming of the protruding ends E, E' of the jumper wires occur respectively when the mesh mats M, M 'are stopped, insulating body W or building element B. In this case, the length of the steps of advancement is chosen in accordance with the step of the transverse wires or an integer multiple of the step of the transverse wires.

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

Using the transverse transport device 19, the finished building element B is led out from the side of the production line XX. At first, the building element B is conveyed by means of a conveyor body 40 provided with a gripper respectively arranged along the production line XX to the transverse conveyor 41. The conveyor body 40 can consist, for example, of a working cylinder, the piston rod of which is arranged to move along the double arrow P14. The cross conveyor 41 consists, for example, of two working cylinders, the piston rods of which are mounted for movement along the double arrow P16 and each equipped with a counter plate 42. The cross conveyor 41 pushes the finished building elements B along arrow P15 from the production line XX to schematically shown tipping device 43, containing several crossbars 44 rotatable in the double arrow P17 44. The building elements B made in the production installation on the edge using the tipping device oystva 43 is brought into a horizontal position and are stacked T.

The installation depicted in FIG. 2 consists, when viewed in the production direction P1, of a device 3 for supplying insulating material, a device 4 for feeding wire mesh webs and a device 45 for feeding wire mats.

The mesh mats M are formed according to the exemplary embodiment of FIG. 1. The supply of pre-fabricated mesh mats M ’is carried out using the feeding device 45 as follows.

Mesh mats M 'are sequentially removed from the stack of nets 46 with the help of a transporting body 47, which can be rotated in the double arrow P18, and placed on the receiving bus 48. Using the retractor 49, the mesh mats M' are fed through the correct device 50 in the direction of the arrow P19 driven by a double arrow P20 feed device 51, for example a feed roll. The retracting device 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 leveling device 50 comprises an input guide 53 for the mesh mat M ', several offset with two rows of training rolls 54 and eccentric rolls 55. The feed roll 51 periodically pushes the mesh mats M' sequentially into the production line XX, where them at a distance from each other and parallel to the canvas K of insulating material and in common with it using pairs of conveying elements 17, 17; 18, 18 ’periodically fed along production line XX to connected processing devices 6, 6’; 7, 7 ’; 8, 8 ’.

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

Schematically depicted in figure 3, the transport device for mesh mats M, M 'and the insulating body W contains a chain conveyor 27 driven by the main feed drive 38 in the direction of arrow P22, which forms the transport path of the insulating bodies W inside the process channel 2. The chain conveyor 27 carries several holders 56, each of which is equipped with a leash 57. The leashes 57 are angled, hook-shaped or like a pin in order to create a reliable connection with the lower side of the insulating body W and, thus, when advanced and the insulating body W to eliminate any slippage between the holders 56 and leashes.

When the insulating body W is reliably fed, the transport device comprises an additional upper chain conveyor 27 ’with respective holders 56’ and leashes 57 ’that act on the upper side of the insulating body W.

3, the feeding elements 17, 18 of the transport device for mesh mats, schematically shown in FIG. 3, comprise a shaft 58 inclined to the vertical, driven through a sleeve 59 by an angular gear 60 and mounted in a counter support 61. An angular gear 60 is driven through a drive shaft 39 by a main drive 38 filing. Each shaft 58 is equipped with several transporting disks 62 arranged at a mutually adjustable distance, which are rotatably mounted on the shaft 58 for adjustment, and after adjustment, they are firmly connected to the shaft 58 by means of a clamping element 63.

The transporting disks 62 have, as shown in FIG. 4a, several recesses 64 of evenly distributed circumference of selectable depth for engaging mats, so that flattened teeth 65 are formed. The number of recesses 64 for engaging mats is selected in accordance with the pitch of the transverse wires of the mesh mats M, M 'with the possibility of reliable capture of the transverse wires Q, Q' of the mesh mats M, M 'by the transporting discs 62 and ensuring the advancement of the mesh mats M, M' without slipping. Due to the inclined position of the shafts 58, the transport discs 62 of each pair of advance members 17, 17 ’; 18, 18 'act not only on one, but also on several transverse wires Q, Q' of the mesh mats M, M ', so that the tensile force is distributed over several wires, and due to this, when moving the mesh mats M, M' are loaded not too much. The inclined position of the shafts 58 provides, in addition, continuous and without slippage further transportation of the mesh mats M, M 'of successive building elements B, moreover, the following successive mesh mats in the joint area may have gaps that occur, for example, when cutting pieces of wire mesh cloths G, G '.

Transporting elements 36, 36 ’; 37, 37 ’of the transport device 35 for building elements made in the same way as the feeding elements 17, 17’; 18, 18 ’of the transport device 16 for mesh mats. Only the transport disks 66 shown in FIG. 4b have recesses 64 of lesser depth for engaging the mats. The feed rolls 10, 10 ’for the wire mesh cloths G, G ″ comprise essentially the same elements as the feed elements 17, 8 of the transport device 16 for mesh mats shown in FIG. The only difference is that the recesses 64 for engaging the mats of the transport disks 66 are substantially deeper, so that they have sharp teeth 67. This shape of the teeth 67 ensures that the teeth 67, which are laterally entering the non-directional wire mesh web G, G 'reliably grasp the transverse wires Q, Q 'of wire mesh cloths G, G' and without slipping advance wire mesh cloths G, G '.

On the installation according to the invention, it is possible to produce building elements B in which the mesh mats M, M ’have a different design, i.e. different pitch of the longitudinal and / or transverse wires, as well as different diameters of the longitudinal and / or transverse wires. The different pitch of the transverse wires must 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 wires S, S ’can be positioned so that they can be reliably welded to the longitudinal wires of both of the mesh mats M, M’ despite this different pitch and diameter of the wires.

On the installation according to the invention, it is possible to produce building elements B in which one and / or both of the mesh mats M, M ’protrude from the insulating body W from one or both sides extending parallel to the production direction P1. To achieve this, either the leashes 57 are lifted or lengthened, or the transport path of the chain conveyor 27 is lifted in such a way that the lower side surface of the insulating body W, which runs parallel to the production direction P1, is respectively raised, due to which one and / or both of the mesh mats M, M 'form on this side, the desired protruding section. The transport path of the upper chain conveyor 27 ’located on the upper side of the insulating bodies W should be respectively lowered or the leashes 57’ should be respectively lowered or extended.

For the manufacture of building elements B, in which the insulating bodies W protrude behind both mesh mats M, M 'with one or both sides parallel to the production direction P1, the transport path of the upper chain conveyor 27' is lifted in such a way that the lower and, if necessary, the upper side surface parallel to the production direction P1 of the insulating body W is respectively lowered or raised relative to the mesh mats M, M ', due to which the insulating body W protrudes beyond both the mesh m ata M, M ’on one or both sides with the desired protruding segments.

The continuous production of building elements B using the installation according to the invention takes place mainly in such a way that the mesh mats M, M 'of successive building elements B are separated from each other only by a negligible narrow dividing seam between the longitudinal wires of successive mesh mats M, M ', and correspondingly the insulating bodies W corresponding to them of the building elements B following each other, follow each other without noticeable gaps.

In the framework of the invention, however, building elements B can be manufactured in which one and / or both of the mesh mats M, M ’protrude from the insulating body W from one or both sides extending perpendicular to the production direction P1. If one or both of the mesh mats M, M ’must protrude from the insulating body W on both sides, then the insulating bodies W of the adjacent building elements B are fed to the processing channel 2 by a conveyor belt 22 with appropriately selectable gaps and advance there with these predetermined gaps. When using an endless web K of insulating material when separating the insulating bodies W, it is necessary to cut a piece corresponding to this gap from the web K of insulating material. Both dividing seams between the mesh mats M, M ’of the building elements B following one after the other lie either exactly opposite each other, or are offset sideways with respect to each other.

For the manufacture of building elements B, in which both mesh mats M, M ’protrude from the insulating bodies W from one or both, extending perpendicular to the direction P1 of production of the sides, mesh mats M, M’ are advanced in the technological channel 2 with a predetermined gap. To obtain this selectable gap between the mesh mats M, M ’of successive building elements B using cutting devices 5, 5’ when forming mesh mats M, M ’from the endless wire mesh cloths G, G’, a piece corresponding to this gap is cut. The gap is limited in that it is necessary to guarantee the possibility of overlapping gaps between the mesh mats M, M 'of successive building elements In the oblique shafts 58 of the transport device 16 for mesh mats and the transport device 35 for construction elements in order to ensure that the mesh advance without slipping mats M, M 'of building elements of V. following each other.

Fig. 5a schematically shows a device 5, 5 ’for cutting mesh mats, which performs a dividing section and thereby continuously separates successive mesh mats M, M’ from the wire mesh cloth G of the grid. 5a, the device for cutting mesh mats shown in FIG. 5a comprises a cutter bar 68, which, when standing on a rib of a wire mesh cloth G, extends vertically parallel to the wire mesh cloth G and is located on one side of the latter. On the other side of the wire mesh web G, a knife bar 69 also extends vertically parallel to the wire mesh web G. The cutter bar 68 and the knife bar 69 are mounted with the possibility of approaching and withdrawing from the wire mesh web G along the double arrow P23 and P24. To cut the wire mesh web G, the cutting bar 68 carries a counter knife 70. The knife bar 69 carries a 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 toward the wire mesh web G. The cutter 68 and the knife bar 69 are mounted for adjustment to position and toward the advancement of the wire mesh web in the direction P3. In the framework of the invention, instead of one reciprocal and one cutting knife, several reciprocal and cutting knives can be used in order to cut each longitudinal wire L of the wire mesh separately or in groups.

Fig. 5b shows another embodiment of a device for cutting mesh mats 5, 5 ', which cuts out a wire mesh G during cutting of a selectable piece, the length of which in the advance direction P3 corresponds mainly to the distance between adjacent transverse wires, the so-called step of the transverse wires or an integer 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 mesh contains a cutter bar 72, which, when standing on the edge of the wire mesh cloth G, extends in a vertical direction parallel to the wire mesh cloth G and is located on one side of the latter. On the other side of the wire mesh web G, a knife bar 73 also extending vertically parallel to the wire mesh web G is arranged. The cutter bar 72 and the knife bar 73 are mounted with the possibility of approaching and withdrawing from the wire mesh web G along the double arrow P23 and P24. To cut a piece from the wire mesh web G, the cutter bar 72 carries two positionally adjustable transverse wires Q of the wire mesh web G of the reciprocating knife 74, and in addition, the mutual distance between the two reciprocating knives 74 can be adjusted by the length of the cut piece. The cutter bar 73 carries two positionally adjustable transverse wires Q of the wire mesh web G of the cutting knife 75, the mutual distance between which can be adjusted to the length of the cut piece and which interacts with the opposite mating knife 75 when cutting the piece. 5b, the mating blades 74 are already shown in their cutting position, while the cutting knives 71 are still moving towards the wire mesh G. The cutting 72 and knife bars 73 are adjustable for positioning in the direction P3 of advancement of the wire mesh and to meet him. In the framework of the invention, in this exemplary embodiment, instead of one reciprocal and one cutting knife, several reciprocal and cutting knives can be used in order to cut pieces for each longitudinal wire L of the wire mesh web G separately or in groups.

Schematically shown in Fig.6, the device 6 for feeding jumper wires contains a base 76, bearing a stopper 77 backward, passing in the direction of the building element In the guide 78 and the cutting device 79. On the guide 78 with the possibility of moving along the double arrow P25 using a drive device ( not shown), for example, of a working cylinder, a crank mechanism, an electric drive, etc., a slide 80 is installed. A slide 80 is arranged on the slide 80 to feed the jumper wire S of the wire D yazhnoy timber 81 acting as a device for feeding the wire clamp 82 and promotes laterally protruding adjusting rail 83.

The advance clamp 82 comprises two wedge-shaped exhaust blocks 84 firmly connected to the exhaust bar 81, two movable wedge-shaped clamp blocks 85 interacting with the exhaust blocks 84 and a spring 86 pressing the clamp blocks 85 to the exhaust blocks 84. The backstop 77 located on the base 76 is made similar to the advance clamp 82 and contains two wedge-shaped locking pads 87 firmly connected to the base 76, two movable wedge-shaped clamping pads 88, etc. dinner 89, pressing the clamping pads 88 against the locking pads 87. A vertical piercing bar 90 is arranged on the protruding end of the adjusting rail 83, which is movable along the double arrow P26 by means of a drive means (not shown), for example, a working cylinder, lead screw, etc. p., and fixation on the adjusting rail 83. At least one piercing needle 91 is placed on the piercing beam 90 so that it extends in the direction of the building element B of the perpendicular with its free protruding end perpendicular to the piercing bar 90. The cross-sectional shape of the piercing needle 91 is predominantly round, with the diameter of the piercing needle 91 at least equal to the diameter of the jumper wire S passed through the insulating body, but preferably larger than the diameter of the jumper wire S. the free end of the piercing needle 91 is provided with a wear-resistant, preferably hardened tip 92.

The described device 6 for feeding jumper wires operates as follows.

Due to the feed movement of the slide 80 facing away from the building element In the direction of the double arrow P25, the piercing needle 91 moves to the building element B. In this case, the tip 92 penetrates the insulating body W and forms a receiving channel C in it during the feed movement. Slide feed movement 80 ends when the tip 92 penetrates completely through the insulating body W and exits from the opposite side of the insulating body W. To facilitate penetration through the insulating body W, the piercing needle 91 or only its tip 92 can be preheated, for example, by means of an inductor or, similarly to a soldering iron, by means of a heating cartridge.

Simultaneously with the feed movement of the piercing needle 91 in the direction of the double arrow P25, the wire D, due to the feed movement of the slide 80, is unwound using the advance clamp 82 from the reel 32 (not shown) through a tempering device 33 having a vertical 93 and horizontal 93 'direction of dressing 33 and along arrow P12 it moves along the input line formed by the exhaust pads 84 and due to the movement of their feed. Due to the feed movement of the slide 80 and thereby the advance clamp 82 in the direction of the building element B, the clamping blocks 85, due to the wedge-shaped design of the exhaust blocks 84, which are placed in addition to the action of the spring 86, are pressed onto the jumper wire S and grab it. To enhance the frictional closure with the jumper wire S, the jaws 85 on their side facing the jumper wire S are further provided with teeth.

At the same time, the jumper wire S advances the clamping pads 88 of the backstop 77 to its spring 89 and to the wider end of the wedge-shaped opening of the stoppers 87, so that the stoppers 87 exhibit practically no resistance to the feed movement of the jumper wire S. The jumper wire S, through the cutting nozzle 94 of the cutting device 79, which coincides with the input line, is passed through the receiving channel C formed in the insulating body I in the previous working cycle by the piercing needle 91. The feed movement of the jumper wire S continues until the beginning of the jumper wire S 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 L and Q of the mesh mat M.

The length of the feed path of the piercing needle 91 and the jumper wire S exactly coincides. At the end of the feed movement, the jumper wire S is separated from the wire D by means of a cutting knife 95 of the cutting device 79. The slide 80 is returned to its original position, and the piercing needle 91 is removed from the receiving channel C, and the jaws 85 of the advance clamp 82 release the wire D, while the clamping pads 88 of the backstop 77 hold the wire D in its position and prevent it from being pulled back in the direction of the roll 32.

In the framework of the invention, it is also possible to remove the already cut off, straightened jumper wire S from the magazine and, using the feeding device 6, to enter along the input line into the preformed receiving channel C. In this case, the training device 33, the backstop 77 and the cutting device 79 are not functioning.

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

In the manufacture of building elements B, jumper wires S, S ’are in most cases fed from both opposite sides of the building element B, so that one feeding device 6, 6’ is provided on each side of the building element B. 6, for illustrative purposes, only the second piercing needle 97 and the additional jumper wire S ’are shown. The piercing needle 97 moves along the double arrow P27, while the jumper wire S ’moves along the arrow P12’. The movement of the piercing needle 97 towards the building element B and the passage of the jumper wire S ’through the insulating body W occur simultaneously and together.

For the simultaneous supply of several jumper wires S to the working cycle on the exhaust bar 81 in the planes ZZ of the jumper wires, several advance clamps 82 are located one above the other at selectable intervals, and on the base 76 there are several reverse stops 77 related thereto located in respective positions stroke and cutting devices 79. To form the corresponding receiving channels C on the piercing beam 90 in the respective planes ZZ of the jumper wires one above the other there are several piercing needles 91. Each piercing needle 91 lies with the input line of the corresponding advance clamp 82, the corresponding cutting nozzle 94 and the corresponding backstop 77 in the horizontal plane Z-Z of the jumper wires (Fig. 7b). When introducing the pre-cut jumper wires into the receiving channel C, each piercing needle 91 lies with the corresponding insertion device also in the corresponding horizontal plane Z-Z of the jumper wires. In order to fit to different thicknesses of the insulating body W, all piercing needles 91 can be jointly advanced in the longitudinal direction by means of a drive device (not shown), for example a spindle, a drive chain, and the like. and are fixed in the piercing beam 90 in its working position by means of a clamping device, for example with a clamping screw.

For the simultaneous supply of several jumper wires S ’to the operating cycle, on the other side of the technological channel 2, corresponding devices are placed on top of each other in Z-Z planes.

Tools for forming the receiving channel for the jumper wires S, S ’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, tip. Pins or hollow needles are preferably configured to preheat their tips to facilitate penetration of the insulating body W.

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 advancing clip 82 of the coaxial jumper wire S, S ’along its input line. The inner diameter of the hollow needle is just such a size that the jumper wire S, S ’can be passed through it. Due to this arrangement, due to the feed movement of the advance clamp 82, the hollow needle and the jumper wire S, S ’move simultaneously and coaxially, the hollow needle forming the receiving channel C simultaneously with the advancement of the jumper wire S, S’. In this exemplary embodiment, the hollow needle with the advance clamp 82 must first be retracted to its original position before the jumper wire S, S ’inserted into the insulating body W can be separated from the supply D of the wire using the cutting device 70.

Schematically depicted in Fig. 7a, the trimming device 8 comprises a cutter bar 98 mounted rotatably in a double arrow P28, parallel to the mesh mats M, M 'of the building element B and carrying several upper knives 99, each of which is located in the zone of the ZZ plane of the jumper wires . In the depicted exemplary embodiments, the mesh mats M, M ’of the building element B are positioned on a rib, so that in Fig. 7a, the plane Z-Z of the jumper wires coincides with the plane of the drawing, and the cutting bar 98 extends vertically. The trimming device 8 further comprises a knife beam 100 mounted pivotally in a double arrow P29, running parallel to the mesh mats M, M ’of the building element B and carrying several lower knives 99, each of which is located in the zone of the Z-Z plane of the jumper wires.

Each upper knife 99, as shown in FIGS. 7a, 7b, 7c, has two recesses 102 for two transverse wires Q of the mesh mat M, so that it becomes possible to rotate the upper knives 99 freely through the transverse wires to their working position between the longitudinal wires L of the mesh mat M. The dimensions and spaces between the recesses 102 are selected in accordance with the pitch of the transverse wires of the mesh mats M. Each upper knife 99 also has two fishing socks 103, which are provided with a triangular guide-centering recess 1 on their lower side 04 for longitudinal wires L.

Each lower knife 101 has two deflecting socks 105, which, when the lower knives 101 are rotated to the cutting position, prevent the lower knives 101 from getting under the longitudinal wires L of the mesh mats M and entangle them there. Between both deflecting socks 105 is a cutting edge 106 for separating the protruding end E of the jumper wire. The upper 99 and lower 101 knives are made of hardened material, with the sides of the cutting edge 106 being further ground.

Cutting device 8 operates as follows. In Fig. 7b, the upper 99 and lower 101 knives are in their initial position outside the building element B. Using respectively driven rotary devices, the cutter bar 98 and, thus, also all the upper knives 99 are rotated together from their original position in Fig. 7b the corresponding direction of the double arrow P28 to the building element B in the centering position in figs. While fishing socks 103 enter between the wires L1; Q of the mesh mat M in such a way that the longitudinal wire L1 to which the cut-off jumper wire S1 is welded is fixed in the guide-centering recesses 104 of the fishing socks 103 of the upper knife 99. The guide-centering recesses 104 are made so that the longitudinal wire L1 when turning the upper the knives 99 are reliably caught and guided, and the upper knife 99, by fixing the longitudinal wire L1, forms a support for it. The transverse wires Q do not interfere with the rotation of the upper knives 99, since they find enough free space in the recesses 102 of the upper knife 99 (Fig. 7). The lower knife 101 remains in its original position.

By means of respectively driven rotary devices, the knife bar 100 and, thus, all lower knives 101, guided by deflecting socks 105, are rotated together at the next working step from their initial position in Fig. 7b in accordance with the direction of the double arrow P29 facing the building element B in the cutting position on figs. In this case, the cutting edge 106 is adjacent to the detachable protruding end E of the jumper wire.

The cutting position shown in FIG. 7c does not mean, however, the interruption of the process P29 of the movement of the knife beam 100, but is only a snapshot of the movement process. The lower knife 101 moves further in the corresponding direction of the double arrow P29 towards the building element B and separates the protruding end E of the jumper wire. After separating the protruding end E of the jumper wire, the cutting bar 98 with all of the upper knives 99 and the knife bar 100 with all of the lower knives 101 are folded back to their original positions. The circumcised building element B is then advanced horizontally in the production direction P1, so that other clearances of the uncut jumper wires fall into the range of the trim device 8.

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

The building element B shown in FIG. 8 in an axonometric view consists of an external M and an internal M ’mesh mat located at a predetermined distance parallel to each other. Each mesh mat M, M ’consists of several longitudinal L, L’ and transverse Q, Q ’wires that intersect and are welded together at the intersection points. The mutual distance between the longitudinal L, L 'and transverse Q, Q' wires is chosen in accordance with the static requirements for building element B. The distances are predominantly equal, for example, in the range of 50-150 mm, so that adjacent longitudinal and transverse wires form square cells, respectively . In the framework of the invention, the cells of the mesh mats M, M ’can also be rectangular and have, for example, a small lateral length of 50 mm and a large lateral length in the range of 75-100 mm.

The diameters of the longitudinal L, L ’and the transverse Q, Q’ wires are also chosen in accordance with static requirements, and they lie mainly in the range of 2-6 mm. The surface of the wires L, L ’; Q, Q ’of mesh mats M, M’ may be smooth or ribbed within the scope of the invention.

Both mesh mats M, M 'are interconnected by several jumper wires S, S' into a form-resistant grid A. S, S 'are welded either, as shown in Fig. 8, with the corresponding longitudinal L, L', or with transverse Q, Q 'wires. The jumper wires S, S ’are alternatively arranged in the opposite direction at an angle, i.e. like fachwerk, due to which lattice body A is given rigidity against shear load.

The gaps between the jumper wires S, S ’and their distribution in the building element B depend on the static requirements for the building element and, for example, are 200 mm along the longitudinal wires and 100 mm along the transverse wires. The mutual gaps between the jumper wires S, S ’in the direction of the longitudinal L, L’ and the transverse Q, Q ’wires are expediently a multiple of the cell spacing. The diameter of the longitudinal L, L ’and the transverse Q, Q’ 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 S, S ’is predominantly larger than the diameter of the longitudinal and transverse wires.

Formed from both mesh mats M, M 'and jumper wires S, S', the spatial lattice body A must not only be dimensionally stable, but also, when it is preferably used as a wall element and / or floor element, to perform the function of a spatial reinforcing element, i.e. e. perceive shear and compressive forces. Therefore, the longitudinal and transverse wires are welded together, like in reinforcing mesh, and the jumper wires S, S ’- with wires L, L’; Q, Q ’of mesh mats M, M’ with minimum strength of welded joints. To perform the function of the spatial reinforcing element of the wire L, L ’; Q, Q 'of mesh mats M, M' and jumper wires S, S 'must consist of suitable materials and have the corresponding values of mechanical strength so that they can be used respectively as reinforcing wires for mesh mats M, M', used as reinforcing nets, and as reinforcing wires connecting both mesh mats M, M '.

In the interval between the mesh mats M, M ’at a given distance from them is an insulating body W, the outer surfaces of which run parallel to the mesh mats M, M’. The insulating body W is used for heat and sound insulation and consists, for example, of foams such as polystyrene foam or polyurethane foam, foams based on rubber and rubber, lightweight concrete such as autoclave or aerated concrete, porous plastics, porous materials based on rubber and rubber, pressed slag, gypsum boards, pressed cement binder plates consisting of wood chips, jute, hemp and sisal fibers, rice husks, straw waste, mineral and glass wool, corrugated cardboard, ressovannoy wastepaper associated brick rubble and molten, recyclable plastic waste. The insulating body W can also be comprised within the framework of the invention of bioplastics, for example of algal foam made from foamed algae or algal cellulose.

The insulating body W may be provided with pre-drilled holes to accommodate the jumper 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 building element B is fixed by means of jumper wires S, S ’that extend at an angle and piercing the insulating body W.

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