Description

FIELD OF THE INVENTION

The aim of the invention is to provide a method of manufacturing a cellular plate, a cellular plate, a method of manufacturing an element of a cellular plate from a steel strip and a production line in accordance with the preambles of the independent claims below. Especially the present invention relates to a new method for the manufacture of cellular boards.

Description of the prior art

A honeycomb plate refers to a structure known per se that is formed of two substantially parallel outer plates and an inner member located between them. Typically, the inner element is also made of plate material, but is arranged in a shape having a direction different from the direction of the outer plates, for example, by forming folds and grooves between them in the plate material. Usually the inner element contains a number of adjacent and parallel straight forms, usually passing essentially through the entire mesh plate. The longitudinal direction of the direct forms of the internal element of the mesh plate in this description is called the main direction. The cellular board resists bending particularly effectively in the direction perpendicular to the direction of the inner member. An internal element of the cellular board of the prior art is a structure that is initially separated from the outer plates, but firmly attached to the outer plates. Typically, the outer plates and the inner element are welded to each other by laser welding or spot welding. It is also known that the outer plates and the inner element can be glued together. In a mesh board, the outer plates and the inner member are usually made of metal, for example stainless steel or aluminum, but other materials may also be discussed. The thickness and material of the outer plates and the inner element, as well as the shape of the inner element, can be sized to suit each situation. The design of the mesh board may provide a design that is substantially lighter and more rigid and that is more resistant to bending than a uniform board structure. The shape of the inner element greatly affects the rigidity and strength of the mesh board. An internal element made of steel may, for example, be made of a plate that is curved into a wave-like shape in which wave vertices are usually welded to the outer plates. The inner elements can also be arranged, for example, in the shape of the letter V, or they can be formed using plates that are located essentially perpendicular to the outer plates, i.e. in the form of the letter I. The inner element can be formed using platinum, which is curved into a honeycomb shape. Rods in the form of tubes with a circular cross-section or other shapes can be used as an internal element.

A problem associated with the manufacture of a conventional cellular board is that it is difficult to attach the internal elements of the cellular boards to the outer plates, especially in the central part of the large area boards. Manufacturing requires expensive equipment. One drawback of conventional honeycomb panels was that usually only honeycomb panels of a certain size could be easily made from the same raw materials.

The main floors of buildings are often made of concrete. The main floor is usually supported on horizontal beams, such as concrete beams. If vertical supports, such as steel supports, are used to support the main floor, special solutions are required to secure the supports. Horizontal supports also required specific design solutions. Insulation of concrete main floors also required their own special solutions.

Objective and Brief Description of the Present Invention

The objective of the present invention is to reduce or even eliminate the problems that occur in the prior art, mentioned above.

An object of the present invention, in particular, is to provide a solution whereby a cellular board can be manufactured using an inexpensive, fast and efficient method.

The aim of the present invention, in particular, is to provide a solution according to which hot-dip galvanized steel plate can be used as a raw material for cellular steel plates without causing damage to the coating.

The aim of the present invention, in particular, is to provide a solution according to which the main floors of buildings can be made, at least in part, from a cellular board and using an inexpensive, fast and efficient method.

To achieve, inter alia, these objectives, the present invention is characterized in that it is presented in distinctive parts in the attached independent claims.

The embodiments and advantages indicated in this description, where applicable, are used in the methods of the present invention, in the cellular board of the present invention, as well as the production line of the present invention, even if not always specifically indicated.

The honeycomb plate comprises first and second substantially parallel outer plates and an internal structure between them. A conventional cellular board in accordance with the present invention is made by attaching to each other a series of individual boards which are made of a plate material, i.e. profiles, which are also called thin plates in this application. In the finished cellular board, each individual profile is designed to form:

essentially flat first outer element,

essentially flat second outer element,

the inner element, which is located to connect the first and second outer elements.

The profiles of the honeycomb in accordance with the present invention are attached to each other so that:

the first outer elements are adjacent and form the first outer plate of the mesh plate,

the second outer elements are adjacent and form a second outer plate of the mesh plate,

profile inner elements are attached to the first and second outer elements, as a result of which they form the inner structure of the mesh plate.

The present invention can be used for the manufacture of honeycomb panels used, for example, on the middle decks of ships or in intermediate ceilings, walls, ceilings and floors of high-rise buildings. Very strong and lightweight supporting structures can be made of a cellular board in accordance with the present invention. For example, a cellular board in accordance with the present invention can be used in cabin or residential modules of ships or buildings. Then, for example, the cabin module can be easily made as a self-supporting structure, on the upper part of which even several floors can be built. Such modules can, for example, form a self-supporting cabin section on a ship or a tall building.

Various profiles and mesh panels in accordance with the present invention can be easily manufactured to suit the situation in question. Cellular panels of various sizes and thicknesses are easily made. The profiles may, for example, be made of steel, aluminum and some other suitable materials. In addition, other materials may be discussed. Lamellar materials and profiles made of them can be coated on one side or on both sides, for example, with a polyvinyl chloride film. The thickness of the plate material may be, for example, from 0.5 to 5 mm or from 0.5 to 3 mm. The length of the profiles in the so-called direction of the inner element can be, for example, from 0.5 to 20.0 m or from 1.0 to 10.0 m. The width of the external profiles can be, for example, from 0.1 to 1 m, from 0.1 to 0.5 m or from 0.1 to 0.2 m. The distance between the external elements of a separate profile can be, for example, from 0.1 to 0.5 m, from 0.05 to 0.4 m or from 0.1 to 0.3 m. The thickness of the finished cellular board is usually approximately equal to the distance between the outer elements in a separate profile. The finished mesh board may contain, for example, from 5 to 1000, from 10 to 200, or from 20 to 100 profiles, fixed side by side. In the direction that can withstand more effort, the length or size of the finished cellular board is usually approximately equal to the length of the profile in the so-called direction of the inner element. The width of the mesh plate in the direction perpendicular to the direction of the inner element may be, for example, from 0.5 to 50 m, from 1 to 25 m, or from 5 to 20 m. The indicated dimensions are only examples. Other sizes are also possible.

It has now been found that durable cellular boards can be made from individual profiles or thin plates that are much smaller than a finished cellular board by fixing several profiles side by side. Thus, a series of relatively narrow plates attached to each other or of the outer elements of a separate profile form the outer plates of the mesh plate.

Since individual profiles are small compared to a finished cellular board, it is easy to manipulate, store and transport raw materials.

One of the most important advantages of the present invention is that it is easy to fasten profiles in accordance with the present invention. Many prior art methods can be used to secure profiles. You can always choose the appropriate method from among the available methods. Thus, even a large mesh board can be easily and economically manufactured.

In one embodiment of the present invention, a separate profile is made of a separate thin metal plate. Edges, recesses, protrusions, folds and other shapes are formed on a thin metal plate using some essentially known method. An advantageous method for forming profiles are other cold stamping methods, for example roller profiling or side crimping. Profiles can be made simply and economically from a thin plate.

In one embodiment of the present invention, mutually fit fastening folds were formed on the outer members or inner members, whereby profiles adjacent to each other were secured by placing the fastening folds in one another. Fixing folds can be formed using the same method and even simultaneously with edges, recesses, protrusions, folds or other specified shapes. By means of mutually fitting fastening folds, it is easy to arrange the profiles next to each other in the desired mutual position.

In an embodiment of the present invention, adjacent profiles are further secured to each other on fastening bends located next to each other using one or more of the following known fasteners, such as:

machine seam

glue,

rivet,

screw,

weld.

Thus, the joints between the profiles will become very strong and stable. For example, on the same mounting bend, adjacent profiles may be glued together with each other, and then the connection may be further secured by securing the profiles to each other using screws or rivets.

In an embodiment of the present invention, a first mounting fold is formed at a first end of the first outer member, and a second mounting fold inserted into the first mounting fold is formed at a second end of the first outer member. The fastening fold in the profile forming one inner element of the mesh plate is usually also formed in conjunction with the fastening folds of two adjacent outer elements.

The fastening folds can be formed in such a way that the fastening folds formed at the ends of three different profiles can be fixed to each other at the same attachment point. When assembling a cellular plate, the fixing bends of the profiles forming two adjacent outer elements and one inner element of the cellular plate are connected and fixed to each other. The fastening can be easily performed, for example, using a well-known, essentially edging machine.

In the present description, the term crosslinking under a press is sometimes also used instead of machine crosslinking, and the term press brake is used instead of a press brake.

Machine stitching i.e. crosslinking under a press is a method known per se to a person skilled in the art.

In an embodiment of the present invention, the fastening fold of each joint profile comprises a double-bent metal plate. When three such connectable fastening folds are sewn together on a machine, a six-layer machine seam is made of metal in the connection of the profiles. A compound of this type is very durable.

In an embodiment of the present invention, the first and second outer elements are arranged substantially in parallel. When the profiles are fixed to each other in such a way that adjacent external elements are arranged in parallel, a cellular plate is easily obtained in which the first and second external plates are fairly even. External elements of a separate profile usually have the same length, i.e. the distance between the first and second ends of the first outer element is approximately equal to the distance between the first and second ends of the second outer element.

In an embodiment of the present invention, the cross section of an individual profile is substantially symmetrical. Profiles of this type are easy to install.

In an embodiment of the present invention, the first and second outer elements are substantially the same in shape or are mirror images of each other. These profiles are easy to install. An advantageous cellular board is at least mainly formed from profiles of only two types, of which the first profiles are installed as external elements and the second profiles as internal elements.

In an embodiment of the present invention, the inner member is secured between the first and second outer members, so that the cross section of some part of the mesh board is substantially in the shape of the letter Z. “Essentially, the shape of the letter Z” means, for example, that the inner member connects the first and second outer elements at their opposite ends. Z-shapes are subject to change. The angle between the outer element and the inner element, for example, can be approximately equal to 90 degrees, or somewhere between 45-135 degrees.

In another embodiment of the present invention, the cross section of the two outer elements and the inner element connecting them is U-shaped or II-shaped, with the result that the first end of the first outer element is attached using the inner element to the first end of the second outer element. Such a shape is usually symmetrical about an axis extending laterally through the inner member. The mold thus obtained may have sharp corners, or its corners may be rounded. It is also possible that the connection between the first outer element and the inner element is pointed and the connection between the second outer element and the inner element is rounded. Then the angle between the outer element and the inner element is usually very close to 90 degrees or exactly equal to 90 degrees.

The cellular board may contain external elements and internal elements located both in the form of Z, and in the form of U.

In an embodiment of the present invention, the inner element or part thereof may be formed with small folds in a zigzag shape, or they may have a wavy shape. Bends or waves can be located either in the direction of the internal element of the profile, or from it.

In one embodiment of the present invention, the elongated reinforcing forms are located on the first outer element, or on the second outer element, or on the inner element, or in all of them, for example, recesses, grooves, protrusions made by cold stamping, for example by means of roller profiling. Reinforcing forms can be located on the outer elements and on the inner element at an angle of 90 degrees to the direction of the inner profile element in the direction of the inner element. The reinforcing forms on the outer elements and on the inner element may have different directions, for example, so that the reinforcing forms on the outer elements can be located at an angle of 90 degrees to the direction of the inner element and on the inner element in the direction of the inner element. Reinforcing forms can be formed so that they start at a first distance from the first end of the outer element and are formed to pass to a point at a second distance from the connection between the outer element and the inner element. The first distance and the second distance may be different, however, so that the reinforcing form advantageously contains the main part of the distance between the first end of the outer element and the connection. In some cases, the length of the reinforcing form is substantially equal to the distance between the first end of the outer element and the joint, or relative to the inner element, it may be substantially equal to the distance between the joints.

In an embodiment of the present invention, the profile comprises as a whole:

part of the first outer plate of the finished mesh board,

part of the second outer plate of the finished mesh board,

part of the internal structure of the finished mesh board.

In an embodiment of the present invention, the mesh plate comprises at least two types of profiles in accordance with the present invention. Then the cellular plate can be made, for example, from U-shaped profiles, of which each other contains reinforcing forms and each other does not contain reinforcing forms. In this way, the strength of the mesh board can be easily and simply adjusted to suit the intended use. The direction of the reinforcing forms may also be different in different profiles of the cellular plate. A mesh board may also contain profiles with both a Z-shape and a U-shape.

A cellular board in accordance with the present invention can be made of steel sheet strip using a method comprising at least the following steps:

roller profiling of fastening folds with a roller bending machine into steel sheet blanks of a certain width and length made of steel sheet strip, and thus turning the blanks into thin plates,

sorting thin plates according to the assembly order,

fixing the thin plates with each other on their mounting bends,

machine stitching the fastening bends of thin plates pre-fixed to each other on an edge bending machine so that they are firmly fixed to each other and so that the thin plates fixed to each other form the structure of the outer plates and the inner element of the mesh plate, resulting in elements of a mesh plates are formed in this way.

Cellular panels or cell panel elements in accordance with the present invention can be made of steel sheet strip in a production line containing at least:

a roll bending machine for forming fixing folds on steel sheet blanks made of steel sheet strip and having a certain width and length, and thus turning the blanks into thin plates,

a bending machine for firmly securing to each other fastening bends of thin plates pre-fixed to each other, so that thin plates fixed to each other form the structure of the outer plates and the inner element of the mesh plate.

A typical installation in accordance with the present invention for the manufacture of a cellular plate of thin plates contains at least the following elements:

a table for assembling a cellular plate,

press brake located in connection with the assembly table,

means for feeding thin plates to a press brake.

In accordance with advantageous embodiments of the present invention, the installation may further comprise at least one of the following distinctive features or one of additional elements:

means for supplying thin plates to the press brake are located in the press brake;

a press brake is arranged to move relative to the assembly table;

a press brake comprises at least two means for cross-linking under the press, which mainly comprise pinch rollers and roll rollers;

a device for placing insulation for positioning the insulation inside the thin plates sewn under the press, on which the insulation is usually fixed with glue; and / or

means for arranging a sealant in the gaps of at least some of the thin plates before sewing these thin plates under pressure.

In an apparatus according to the present invention, three thin plates are simultaneously fed into a press brake, i.e. thin plates that form the outer parts and the inner part of the mesh plate element.

The process can be performed even faster and more efficiently if the means for feeding the thin plates to the press brake are located in the press brake and if the press brake is movable relative to the assembly table. Then you can use the installation in accordance with the present invention so that when the press brake sewed thin plates with each other, i.e. when it has moved from the first end of the assembly table to its second end, then it moves the following thin plates to the appropriate position for processing when it returns to its original position. Then, the press brake can begin directly a new crosslinking cycle, i.e. it can again move from the first end of the assembly table to its second end and at the same time make all the necessary seams. The seams under consideration are, for example, typically the upper and lower seams of thin plates.

The press brake can contain any suitable amount of crosslinking means, for example, two, three, four, five, six, seven, eight, nine or ten means.

When, in an embodiment of the present invention, means are used to place the joint insulation material in the gaps between at least some of the plates before these plates are sewn under the press, i.e. stitched on the machine, then the seams can be simultaneously sealed. The sealant may, for example, be an adhesive such as urethane adhesive.

The installation or production line in accordance with the present invention may further comprise additional means, such as an additional table, onto which the elements of the cellular board of a given size are moved from the assembly table. Elements of a cellular plate are brought to the end on an additional table; for example, additional equipment, edging, required holes, etc. carried out at this stage.

The usual method of manufacturing a cellular plate of thin plates in accordance with the present invention is characterized in that the method includes at least the following steps:

a) the location of the first thin plates on the assembly table;

b) stapling under a press or machine stitching of thin plates with each other using an edge-bending press, so that the plates fixed to each other form the structure of the outer plate and the inner element of the mesh plate;

c) the location of the second thin plates in conjunction with the first thin plates;

d) press stapling or machine stitching of the second thin plates to each other and to the thin plates fixed to each other in the first step by means of an edge-bending press, so that they also form the outer plate and the inner element of the mesh plate;

e) repeating steps c) and d) until a cell element of a predetermined size is obtained.

According to an embodiment of the present invention, at least three thin plates, i.e. thin plates forming the first and second outer parts and the inner part of the mesh plate element are sewn under the press with each other at the same stage. Then you can make all the seams between them at the same time.

A typical supporting flat building structure in accordance with an embodiment of the present invention comprises:

a first flat cellular slab in which internal elements are located mainly in the first direction;

a second flat cellular plate in which the internal elements are located mainly in the second direction;

a flat insulating layer fixed between the first and second cellular boards.

The first and second cellular plates and the insulating layer between them are located mainly parallel, as a result of which the surfaces of the first and second cellular plates directed from the insulating layer form the outer surfaces of the structure.

In an embodiment of the present invention, the first direction substantially coincides with the plane direction of the first flat cellular board, and the second direction substantially coincides with the plane direction of the second flat cellular board.

In an embodiment of the present invention, the first direction and the second direction form a significant angle between themselves. Thus, the cellular slabs of the structure have multidirectional internal elements. This strengthens the design. In an embodiment of the present invention, the first direction and the second direction are substantially perpendicular to each other. In this case, this design is particularly robust.

In an embodiment of the present invention, the first and second cellular boards are steel cellular boards.

For example, when a structure in accordance with the present invention is used as the main floor of a building, an elongated support can be attached to the outer surface of the mesh board. Typically, the support is located substantially perpendicular to the direction of the plane of the first mesh board.

In an embodiment of the present invention, the support is attached by laying the support to the outer surface of the first mesh board. Such a support gasket is arranged to contact the outer surface of the first mesh plate, so that the support gasket distributes the load applied by the support to the first mesh plate over an area that is larger than the surface of the end of the support, or over the contact area of the support gasket. The contact area of the support gasket is substantially larger, predominantly greater than 100%, or even more predominantly greater than 300%, compared with the area of the end of the support attached to the support gasket protruding on the plane of the first mesh board.

In an embodiment of the present invention, the support gasket is arranged to contact the outer surface of the first honeycomb plate, at least substantially only on the outer edges of the contact area of the support gasket. A design of this type distributes the forces exerted by the support on the cellular slab over a large area of the cellular slab.

In an embodiment of the present invention, the support gasket consists mainly of plate material in a part connecting the outer surface of the first honeycomb plate and the support. The direction of the plane of this plate material differs, at least mainly from the direction of the plane of the first cellular board. This plate material may take the form of, for example, a cone or a pyramid with a lower part located on a mesh plate.

Detailed description of examples in the drawings

Similar reference numbers are used for corresponding elements in various embodiments. In some drawings describing the present invention, elements are depicted with inaccurate dimensions for clarity. For example, gaps between profiles are usually increased.

Figure 1 depicts a cellular plate 401 of the prior art. The mesh plate 401 comprises a first outer plate 402 and a second second outer plate 403 parallel to it. Separate inner structures 404 are welded between the outer plates.

Figure 2 depicts in the main form part of the cellular plate 1 in accordance with the present invention. The mesh plate 1 is assembled from a number of metal profiles 5 in a Z-shape. Each profile 5 contains a first element 6 and a second element parallel to it 7. The outer elements are connected using a one-piece inner element 4, which forms an element made as a whole with them. Profile 5 is bent from a flat metal plate, for example, by roll profiling on a roll bending machine or by forming the first and second folds 8 and 9 on it. The first fold 8 is located between the first outer element 6 and the inner element 4. The second fold 9 is located between the second outer element 7 and the inner element 4. The inner element 4 is bent at approximately right angles to the outer elements. When the profiles are attached to each other, for example, by welding at their contact points 10, the first outer elements form the first outer plate 2 of the mesh plate and the second outer elements form the second outer plate 3 of the mesh plate.

The mesh plate 1 in FIG. 3 corresponds otherwise to the mesh plate 1 in FIG. 2, and the ratio of the length of the inner element 4 to the length of the outer elements 6 and 7 is substantially greater than the ratio of the inner element 4 to the length of the surface 6 and 7 in FIG. 2. Although the profiles 5 in both drawings are made of a metal strip with the same thickness, the mesh plate 1 in Figure 3 essentially has increased strength.

The mesh plate 1 shown in FIG. 4 is formed from a series of mutually identical and symmetrical profiles 5, 5 '. Figure 5 shows in an enlarged view the point 10 of the contact between the two profiles 5, 5 '. At the contact point 10, a first mounting fold 11 'is formed on the first fold 8' of the first profile 5 '.

Neighboring profiles 5 and 5 'can, for example, be welded to each other at the contact point 10 between the end 12 of the outer element 6 and the fastening fold 11' located next to each other. Other attachment points between the profiles are located in a similar manner.

The cellular plate 1 shown in Fig.6, is formed from a number of mutually identical and symmetrical profiles 5, 5 '. 7 depicts an enlarged view of the contact point 10 between two profiles 5, 5 '. At the contact point 10, a first mounting bend 11 is formed in the form of a groove on the second bend 9 of the first profile 5.

Other attachment points between the profiles are located in a similar manner.

Fig. 8 shows how a mesh plate 1 is formed from a series of mutually identical and symmetrical profiles 5, 5 '. On the first bend 8 of the first profile 5, at the first contact point 10, a first fixing bend 11 is formed, comprising a groove 15 and a protrusion 16 located adjacent to each other. At the end 13 'of the first outer element 6' of the second profile 5 ', a hook-shaped second fastening fold 14' is formed. The fastening fold 14 'is inserted into the groove 15 and the protrusion 16 so that the adjacent first outer elements 6 and 6' will be located in the same plane after fixing.

Neighboring profiles 5 and 5 'can, for example, be glued to each other at the point of contact 10 between the end 13' and the fastening fold 11 located next to each other. Other attachment points between the profiles are located in a similar manner.

A third mounting fold 22 ′ comprising a recess 23 ′ is formed adjacent to the second fold 9 ′ of the second profile 5 ′ at the second contact point 10 ′ in FIG. A hook-shaped fourth fastening fold 25 is formed at the second end 24 of the second outer element 7 of the first profile 5. The fastening fold 25 is inserted into the groove 23 'so that the adjacent second outer elements 7 and 7' will be located in the same plane after fixing.

Fig. 9 is an enlarged view of the first contact point 10 shown in Fig. 8 and how the profiles 5 and 5 'are fixed here by machine stitching. The groove 15, the protrusion 16 and the fastening fold 14 'are pressed in the direction indicated by the arrow to the stationary die cutting knife 20. Thus, the profiles 5 and 5' made of a thin plate are fixed to each other.

FIG. 10 is an enlarged view of the second contact point 10 ′ shown in FIG. 8, and how profiles 5 and 5 ′ are fixed here by machine stitching. The groove 23 'and the fastening fold 25 are pressed in the direction indicated by the arrow to the stationary die cutting knife 20. Thus, the profiles 5 and 5' made of a thin plate are fixed to each other.

11 depicts a mesh plate 1, similar to the mesh plate in figure 4, with the result that this plate is formed from a number of mutually identical and symmetrical profiles 5, 5 ', 5' '. At the first contact point 10, the first mounting fold 11 'is formed on the first fold 8' of the profile 5 '. The end 12 of the first outer element 6 of the profile 5 is inserted into the fastening fold, so that the adjacent outer elements 6 and 6 'will be in the same plane. Neighboring profiles 5 and 5 'can, for example, be welded to each other so that they are fixed at the contact point 10 between the end 12 of the outer element 6 and the fastening fold 11' located next to each other. A screw or rivet 31 is also installed through the end 12 and the mounting fold 11 'to provide a connection.

At the second contact point 10 ′ in FIG. 11, a fastening fold 14 ′ is formed at the end 13 ″ of the second outer element 7 ″ of the profile 5 ″. The fastening fold 14 ″ is located adjacent to the inner element 4 ′ of the adjacent profile, so that the adjacent second outer elements 7 ′ and 7 ″ will be in the same plane. Neighboring profiles 5 and 5 'can, for example, be welded or glued to each other at the contact point 11 between the fastening fold 14' and the inner element 4 'located next to each other. A screw or rivet 31 is also installed through the fastening fold 14 'and the inner member 4' to provide a connection. Other attachment points between the profiles in FIG. 11 are arranged in a similar manner.

12 is a cross-sectional view of a mesh board in accordance with a seventh embodiment of the present invention. The cellular plate 1 is assembled from a series of metal profiles 5, 5 'having the shape of the letter U. Each profile 5, 5' contains a first outer element 6 and a parallel second outer element 7. The outer elements are connected by an inner element 4, which forms an element made as one with them. Profile 5 is bent from a flat metal plate, for example, by roll profiling or side compression of the first and second folds 8 and 9 on it. The first fold 8 is located between the first outer element 6 and the inner element 4. The second fold is between the second outer element 7 and the inner element 4. The inner element 4 is bent at approximately right angles to the outer elements. When the profiles are fixed to each other, for example, by welding and / or using screws or rivets 31 at their contact points, the first outer elements form the first outer plate of the mesh plate and the second outer elements form the second outer plate of the mesh plate.

Fig.13 depicts a cellular plate 1, similar to the cellular plate in Fig.12, which is formed from a number of mutually identical and symmetrical U-shaped profiles 5, 5 '. In a separate profile, the inner element 4 is formed with folds 22 in a zigzag shape. Bends can be located all the way in the direction of the inner element, i.e. from the first outer edge of the inner element to its second outer edge. With the help of bends, it is possible to change the strength and flexibility characteristics of the profiles and, thus, the strength and flexibility characteristics of the mesh plate as necessary.

Fig. 14 is a cross-sectional view of a cellular board in accordance with a ninth embodiment of the present invention. The honeycomb plate 1 is formed from a series of metal profiles 5, 5 'having the shape of the letter U. Each profile 5, 5' contains a first outer element 6 and a parallel second outer element 7, the outer elements being connected by an inner element 4, which forms an element, made as one unit with them. The elongated reinforcing molds 20, 20 ′ were formed in the profile 5 both on the outer members 6, 7 and on the inner member 4 of the mesh board 1. The reinforcing molds were formed, for example, by roll forming or side crimping. Reinforcing forms 20, 20 'were formed both on the outer elements 6, 7 and on the inner element so that they extend from the direction of the inner element. The reinforcing molds 20, 20 ′ were formed so that they start at a first distance from the first end 6 ″ of the surface 6, and so that they extend to a second distance from the joint 6 ″ between the outer member 6 and the inner member 4. For clarity, FIG. 14 does not show securing profiles 5 to each other.

Fig. 15 depicts a cellular slab 1 similar to the cellular slab of Fig. 14, whereby the slab is formed from a series of mutually identical U-shaped profiles 5, 5 'with reinforcing forms 20, 20' formed thereon. On the outer elements 6, 7, reinforcing forms 20, 20 'were formed parallel to the direction of the inner element, and on the inner element 4 they are formed from the direction of the inner element. For clarity, FIG. 15 does not show the fastening of the profiles 5 to each other.

Fig.16 depicts the outer element 6 and the inner element 4 in accordance with the present invention. Profiles or thin plates 4 and 6 were formed from a flat metal strip by roller profiling of the mounting bends on their longitudinal edges and reinforcing forms 20 in the longitudinal direction of the profile between the edges of the surface 6. The fixing fold 13 is located on the first edge 11 of the outer element 6, and the fixing fold 14 is located on the second edge 12 of the outer element. A fixing fold 23 is located on the first edge 21 of the inner member 4, and a fixing fold 24 is located on the second edge 22 of the inner member.

Fig. 17 shows an example of the formation of a mesh board 1 from individual profiles, i.e. from external elements 6, 6 ', 6' ', 6' '' and internal elements 4, 4 '. The fastening fold 14 of the second edge of the outer element 6, the fastening fold 13 'of the first edge of the outer element 6' and the fastening fold 23 of the first edge of the inner element 4 are inserted into each other at the contact point 10. Similarly, the fastening fold 14 ″ of the second edge of the outer element 6 ″, the fastening fold 13 ″ of the first edge of the outer element 6 ″ and the fastening fold 24 of the second edge of the inner element 4 are inserted into each other at the contact point 10 ′. The profiles are fixed to each other by machine stitching at the contact points 10 and 10 '. Then, the outer elements 6 and 6 'form the first outer plate 2 of the mesh plate 1, and the outer elements 6' 'and 6' '' form the second outer plate 3 of the mesh plate 1. At the attachment points, the compressed material has six layers.

On Fig and 17 shows that the outer elements located opposite each other, such as 6 and 6 ', have the same shape. Surface elements 6 and 6 'were installed only in a mutually opposite position. Thus, the cellular plate 1 is formed using profiles of only two different shapes - one for the outer elements and the other for the inner elements.

The width or run A of the outer element depicted in FIG. 16 may be, for example, approximately 0.15 m. The width B of the inner element depicted in FIG. 16 may be, for example, approximately 0.9 m. The thickness of the entire mesh plate 1, shown in FIG. 17, will then be approximately B plus the thickness of the two metal plates used, in other words, for example, 0.095 m.

During assembly, insulation can be installed in the space 30 inside the mesh board. The insulation may be, for example, a mineral wool gasket, which substantially completely occupies the space 30. In one space 30, a mineral wool layer having a cross section of approximately rectangular shape can be arranged. This insulation may have dimensions that, for example, are A × B, using the indicated dimensions. In the direction transverse to the cross section shown in the drawings, the insulation may, for example, have the length of the entire mesh board or profiles 4 and 6.

Fig. 18 depicts a production line in accordance with the present invention for manufacturing a steel mesh plate member from a steel sheet strip. Typically, at least the main part of the devices of the production line in accordance with the present invention and, preferably, all devices are located in the same building. The production line operates as follows.

Steel sheet rolls are stored in the storage compartment 101. The storage compartment contains many rolls. If necessary, the steel sheet rolls are moved using the device 102 to move the rolls from the storage compartment to the first coiler 103. The steel sheet is unwound from the first coiler to the device (104) for longitudinally cutting the sheet into strips. A device for longitudinally cutting a sheet into strips cuts a steel sheet into sheet strips with a width and thickness determined in accordance with a predetermined cell element under consideration. For example, if the width B of the inner element 4, which mainly determines the thickness of the given mesh plate, is 100 mm, then the width of the necessary strip for the inner element is 100 mm + the amount of material required for the fastening bends 23 and 24, in other words, the material necessary for machine stitching.

The strips cut on the device 104 for longitudinally cutting the sheet into strips are moved to the second coiler 105. If necessary, strips of different widths can also be made and stored in the storage compartment. The cut strips are unwound from the second coiler 105 onto the strip cutter 106. The cutting device 106 cuts the strip into steel sheet blanks with a predetermined length. The strip is cut along the length determined by the length of the given mesh plate.

Then, the steel sheet blanks are moved from the cutting device 106 to the roll bending machine 107. The roll bending machine 107 forms fixing bends 13, 14, 23, 24 (see FIGS. 1 and 2) on the billets, as well as any other shapes, such as reinforcing bends 20. Thus, the workpieces are transformed into thin plates or profiles that form a mesh plate. The width of the thin plate 6, 6 ′ forming the outer plate 2, 3 of the mesh plate determines the run A of the plate portion and the distance between the internal elements 4, 4 ′. The width B of the thin plate 4, 4 ', forming the internal structure, determines the thickness C of the finished mesh plate and, thus, also its strength. Typically, the wider the inner element, the stiffer and stronger the cellular board is.

From the roller bending machine 107, the thin plates are moved onto the table 108 for sorting the thin plates. A table 108 for sorting thin plates is needed as a place for sorting and storing thin plates. On the sorting table 108, thin plates are sorted according to their assembly order. The sorted thin plates are moved from the sorting table 108 to the table 109 for pre-assembly of the thin plates. On the sorting table, thin plates are pre-fixed to each other on mounting bends before stitching. At this stage, it is possible, for example, to pre-fix one profile blank, in other words, two outer thin plates 6 and 6 'and an inner thin plate 4 connecting them.

Thin plates pre-fixed to each other are moved forward from the pre-assembly table 109 either to the gluing device 111, or to the insulation device 110, or to the mesh plate assembly table 113.

The gluing device 111 can, for example, extrude glue into the gaps between pre-fixed thin plates, for example, before machine stitching into a seam that can be sewn on a machine. This can provide a sealed mesh board and increase the strength of the mesh board.

Using the device 110 for applying insulation, it is possible to arrange the insulation on at least part of the thin plates or in the gaps between the thin platinum. The insulation is installed on a pre-cross-linked honeycomb section, for example, before installation and machine cross-linking of the next pre-assembled profile blank. The insulation can be glued between the plates as needed.

On the mesh board assembly table 113, thin plates pre-fixed to each other are sewn onto the machine using a hemming machine 112 so that they are firmly fixed to each other on their mounting bends, and thus parts of the mesh plate element are formed. Edging machine 112 is typically positioned to move along one side of assembly table 113, for example along rails. For example, you can proceed as follows: the already sewn cell plate element is moved to the assembly table along the width of the thin plate, after which new pre-assembled thin plates are fed for stitching. The number of thin plates sewn together determines the width of the mesh plate.

The elements of the mesh plate of a given size are moved from the assembly table 113 to the additional table 114 of the element of the mesh plate. On an additional table 114, the honeycomb plate is brought to an end, for example, additional equipment, edging, necessary holes, etc. carried out at this stage. The finished elements of the mesh plate are moved using the device 115 for lifting the element of the mesh plate from the additional table 114 to the compartment 116 for storing the elements of the mesh plate. Conventional lifting device 116 raises the finished cell element and at the same time supports it at its ends, which can be disconnected. In the storage compartment 116, items may be stored horizontally or vertically.

The apparatus depicted in FIGS. 19 and 20 may illustrate an example of stitching on a machine, i.e. press brake 112 and assembly table 113.

Figs. 19 and 20 depict an apparatus for manufacturing a cellular plate element from thin plates 202, 203. Fig. 19 depicts an apparatus in accordance with an embodiment of the present invention, when viewed from a first direction, i.e. from one end. The installation comprises an assembly table 204 of the cell plate element 201 and a press brake 205 located in connection with it. A press brake 205 is arranged to move on wheels 206 supported by guides 207 on one side of the assembly table 204. The press brake 205 contains the necessary power sources, such as electric and / or hydraulic motors, automatic control devices, clutches and gearboxes and other necessary equipment, known essentially to a person skilled in the art.

Press brake 205 comprises shaft devices, pinch and roll rollers 208, known per se to a person skilled in the art. Advantageously, the assembly table 204 is driven in such a way that the finished part of the mesh plate element can be moved forward onto the table, so that the next thin plate can be fed for stitching. In addition, FIG. 19 depicts means 209 for positioning an insulating material, such as urethane adhesive, between at least some of the plates before stitching these thin plates on the press brake.

On the assembly table 204 of the mesh plate element, a press brake 205 sews the pre-fixed thin plates firmly with each other on their mounting tabs, and thus the mesh plate element is formed. The operations, for example, are performed as follows: the already sewn part of the mesh plate element is moved to the assembly table along the width of the thin plate, after which new pre-assembled thin plates are fed so that they can be stitched with the component of the mesh plate element. The number of thin plates sewn together determines the width of the mesh plate.

Fig.20 depicts the installation of Fig.19, shown on one side or in a direction transverse to the direction of Fig.19. The arrow 211 in the drawing shows the direction of movement of the press brake 205. In addition, the drawing shows means 210 for feeding thin plates to the press brake. When the press brake 205 stitched the thin plates 202, 203 with each other and with the pre-stitched thin plates, in other words, when it moved from the first end to the second end of the assembly table 204, then it will move the following thin plates to the exact processing position when he will return to his original position. Then, the press brake can directly start a new crosslinking cycle, i.e. move again from the first end of the assembly table to its second end and at the same time carry out all the necessary seams. Typically, all considered seams, for example, are the upper and lower seams of a thin plate.

21-24 depict a flat building supporting structure 330 comprising a first flat mesh plate 331, a second flat mesh plate 332, and a flat insulating layer 333 that is secured between the first and second mesh plates. The internal elements 334 of the mesh plate 331 are parallel to the plane of the mesh plate 331 and are generally directed in the first direction. The internal elements 335 of the mesh plate 332 are parallel to the plane of the mesh plate 332 and are generally directed in a second direction. The first and second cellular boards and the insulating layer between them are generally parallel. The inner elements 334 and 335 are generally perpendicular to each other. The surface of the first mesh plate 331 directed from the insulating layer 333 is the lower surface 336 of the structure 330. The surface of the second mesh plate 332 directed from the insulating layer 333 is the upper surface 337 of the structure 330. The first and second mesh plates 331 and 332 are, for example, steel mesh boards in accordance with Fig.16 and 17 or 1-15.

Figures 22-24 depict structures 330 that are intended as load-bearing structures of buildings. The lower surface 226 of the structure is supported on an elongated support 340. The support may be, for example, made of steel or concrete. The support 340 is substantially vertical, that is, substantially perpendicular to the generally horizontal direction of the structure 330. The support 340 is attached to the bottom surface 336 of the mesh plate 331 by means of a support gasket 341. As for the support, the gasket of the support includes a mounting portion 351, which sits on the support. The support gasket 341 distributes the load applied by the support 340 to the lower surface 336 of the structure through its enlarged portion 342 over an area that is larger than the end of the support 340, i.e. by the contact area of the support gasket. The contact area is defined by the edges 343 of the enlarged portion 342 of the support gasket, which are attached to the bottom surface 336. The contact area of the support gasket 341 is substantially larger than the area of the end of the support 340 attached to the support gasket protruding on the lower surface. The support gasket is attached to the lower surface 336 of the structure 330 by means of fasteners 353, for example by means of bolts, or by welding.

In the embodiment of FIG. 22, the enlarged support gasket portion 342 is a flat plate. The flat plate, for example, may be a steel plate with a thickness of at least 10 mm. In practice, there is a risk that even a relatively thick plate 342 may be bent so that the edges 342 are detached from the bottom surface 336. This reduces the contact area and the load of the support 340 will change direction on an even smaller area relative to the structure 330.

In the embodiment of FIGS. 23 and 24, the enlarged support gasket portion 342 is mainly made of plate material and is located in connection with the lower surface 336 of the structure only at the edges 343 of the enlarged part 342. The plane direction of such plate material is essentially different from the plane direction the lower surface 336. However, the edges 343 can be bent mainly in the direction of the plane of the lower surface 336. A structure like this always distributes forces from the side of the support 340 directed to the structure s 330, over a large area of the lower surface 336. The material of this plate-shaped enlarged part may be a steel plate with a thickness, for example, from 3 to 10 mm.

23 depicts an enlarged portion 342 having a generally truncated pyramid shape.

24 depicts an enlarged portion 342 having a trough shape. In a vertical cross section, the trough of the enlarged portion 343 is generally in the shape of the letter V or U, open towards the bottom surface 336.
