    BACKGROUND OF THE INVENTION The invention relates to a plate which can be used, for example, as an end plate of a container.
    It is challenging to produce large plates, for example in the order of square meters, which are used, for example, as the ends of tanks. The plate must be sufficiently rigid and straight, but at the same time also reasonably lightweight and simple to handle. One plate is disclosed in FI 126050.
    Brief description of the invention The object of the invention is to provide a new type of plate and container. The solution according to the invention is characterized by what is stated in the independent claims. Preferred embodiments of the invention are the subject of dependent claims.
    In the solution shown, the plate is formed of a plurality of adjacent profiles, which profiles are hollow extruded or extruded profiles, the walls of which comprise a plastic material. The profiles are essentially straight and rigid. The profiles are arranged side by side and connected to each other. The cross section of the profiles is such that when an adjacent profile is connected to each side of the profile so that the two sides of the profile are against the adjacent profile, more than 50% of the surface area of the outer surface of the profile is against the adjacent profile. Such a plate is reasonably lightweight, dimensionally accurate and has a good bending resistance.
    According to one embodiment, the cross-section of the profiles is a triangle, wherein the two sides of the triangle form said two sides of the profile. There is an oblique structure between the first and second surfaces of such a plate and the plate withstands bending very well.
    N According to another embodiment, the cross section of at least some of the profiles is an isosceles triangle. In this way, symmetry in the structure of the D plate can be easily achieved.
    = According to another embodiment, the cross section of at least some profiles is an equilateral triangle. Such a solution further facilitates the formation of the plate and the result is easy to obtain.
    3 According to another embodiment, the cross section of at least some of the profiles is a rectangular triangle. With such a solution, both a sloping structure and a perpendicular structure between the surfaces can be obtained between the first and second surfaces of the plate structure.
    According to another embodiment, at least some of the profiles in the plate are hollow. This makes the plate simple and easy to form.
    According to another embodiment, at least some of the profiles in the plate are filled. By filling in the profiles, various desired properties are obtained on the board with reasonable simplicity.
    According to another embodiment, the cross-sectional shape of all profiles is the same. In this case, the production of the board is simple and the properties of the board can be easily desired.
    The plate according to any of the above embodiments can be used to form, for example, at least one end of a container to be mounted on the ground or an upper end and / or a lower end, i.e. a bottom, of a vertical container. The tank can thus be horizontal or vertical, or a well or pumping station or other similar product. The plate forming the end of the container can be made larger than the cross-section of the container. In this way, a self-anchoring tank to be installed in the ground can be formed, i.e. a tank in which the structure itself has a structure enabling anchoring. The plate then extends beyond the shell of the tank, and on top of this plate extending outside the tank, a ground mass can be arranged to counteract the lift caused by the groundwater to the tank. Such a method of anchoring the tank is cost-effective when a separate concrete slab or other anchoring structure is not required. By all means, the invention makes the structure of the container advantageous.

    DETAILED DESCRIPTION OF THE INVENTION Figure 1 illustrates a plate 1 and a step in its forming process.
    The plate 1 is formed of several adjacent profiles 2. The profiles 2 are extruded or extruded profiles.
    The plate 1 can also be called a cell plate or a cell plate structure.
    The profiles 2 can be made of, for example, a thermoplastic material, such as polyethylene PE or polypropylene PP, or a composite material.
    In the first stage of the production of the plate 1, a straight profile is extruded or extruded.
    The formed profile is cut into pieces of suitable length.
    The cut profile pieces are placed side by side and joined together to form a plate.
    The profiles are cut into, for example, profiles 0.5 to 10 m long 2. The profiles 2 can be, for example, 20-200 mm wide in the width direction and 50-500 mm high in the height direction.
    In other words, the sides 2a and 2b of the profiles 2 can be, for example, 50-500 mm high and the bases 2c and 2d of the profiles 2 20-200 mm wide.
    At least three profiles 2 are arranged side by side.
    Up to dozens of profiles 2 can be arranged side by side in the plate.
    The width of the prepared plate 1 can be, for example, 0.5-10 m.
    The wall thickness of the profiles 2 can be, for example, 2-20 mm.
    The profiles 2 are rigid, in which case they are preferably formed, for example, from non-foamed = thermoplastic material.
    N In the embodiment of Figure 1, the profiles 2 are joined together by extrusion welding.
    The profiles 2 are arranged side by side in a horizontal plane and a first extruder 3a is arranged above them and a second extruder 3b is arranged below them.
    E 30 The extruders 3a and 3b extrude a material which joins the profiles 2 to each other.
    Preferably, the material to be extruded by the extruders 3a and 3b is the same material D from which the profiles 2 are formed. The extruders 3a and 3b can thus be used to join the profiles 2 NN so that the extrusion welding is carried out simultaneously on both sides of the plate 1 to be formed.
    The joining can also be done in such a way that the extrusion
    drying is done first on the first side and then on the second side.
    The extruder 3a, 3b can be used to connect two profiles at the same time, i.e. to make one seam, or it is possible to join several profiles at the same time, i.e. to make several seams at the same time.
    There can be one extruder 3a, 3b or several extruders side by side on one side of the plate to be manufactured.
    In Figure 1, the profiles are thus placed horizontally side by side, but if desired, the profiles 2 can be placed vertically side by side, i.e. they can be stacked before joining them.
    Instead of extrusion welding, the profiles 2 can also be joined together by wire, ultrasonic, laser or butt welding.
    Furthermore, the profiles 2 can also be connected to one another, for example by gluing or by a mechanical connection, such as the dovetail connection shown in Fig. 9, or by some other suitable connection method.
    The profiles 2 are thus formed into hollows by extrusion.
    In the finished plate 1, the profiles 2 can also be hollow.
    According to one embodiment - however, the profiles 2 are filled either before they are connected to each other or when they are attached to the plate 1. By filling the profiles 2, the properties of the plate 1, such as bending stiffness, can be easily adjusted.
    The profiles 2 can be filled, for example, with foam welded to the walls of the profile.
    For example, foamed polyethylene can be fitted inside profiles made of non-foamed polyethylene.
    Some other foam or other filling can also be fitted inside the profiles 2.
    In addition to or instead of foam, another material such as wood, steel, aluminum, concrete or glass can be fitted inside the profiles 2, for example as a stiffener.
    The profiles 2 can also be stiffened by fitting additional stiffeners inside the walls of the profiles 2.
    Additional stiffeners can also be fitted, for example, to welds between profiles o 2.
    The additional stiffeners can be, for example, steel, glass or aluminum or some other suitable material. > In the embodiment of Figure 1, the sides 2a and 2b of the profiles 2 are against the sides 2a and 2b of the adjacent = profiles 2.
    The bases 2c and 2d of the profiles 2 form the surfaces of the plate 1A 30.
    The sides 2a and 2b of the profiles 2 are longer than the bases 2c and 2d of the profiles 2.
    E In this embodiment, therefore, when an adjacent profile 2 is connected to each side of the profile 2 so that the two sides 2a and 2b of the profile 2 are against the adjacent profile D 2, more than 50% of the outer surface area of the profile 2 is against the adjacent profile 2 2.
    In this case, for example, a good plate N 35 with very good bending properties is obtained1.
    The outer circumferential profile 2 may also be rectangular in shape, as shown in Figure 1. According to one embodiment, the outer circumferential profile may also have a support structure, which may be, for example, a partition wall extending obliquely from corner to corner. 5 This partition may be substantially similar in material and, for example, thickness to the wall forming the outer circumference.
    Due to the sloping partition wall, the profile 2 has two triangular structures, whereby there is also an oblique structure between the first surface and the second surface of the plate 1.
    In the embodiments of Figures 2-9, the cross section of the profiles is triangular.
    In this case, the walls forming the outer circumference of the profiles also provide an oblique structure between the first surface and the second surface of the plate.
    The bases 2c of the triangular profiles 2 form the surfaces of the plate 1 and the sides 2a and 2b of the triangular profiles 2 are against the sides 2a and 2b of the adjacent triangular profile 2.
    Also in these embodiments, therefore, when an adjacent profile 2 is connected to each side of the profile 2 so that the two sides 2a and 2b of the profile 2 are against the adjacent profile 2, more than 50% of the outer surface area of the profile 2 is against the adjacent profile 2.
    In the embodiment of Figure 2, the shape of the triangle is an isosceles triangle.
    The base 2c of the triangular profiles 2 is shorter than its sides 2a and 2b.
    Also in the embodiment of Figure 3, the shape of the triangle is an isosceles triangle.
    The base 2c of the triangular profiles 2 is longer than its sides 2a and 2b.
    In the embodiment of Figure 3, there is a right angle between the sides 2a and 2b.
    In the embodiment of Figure 4, the shape of the triangle is an equilateral triangle, i.e. the base 2c is the same length as the sides 2a and 2b.
    In this case, the production of the plate is simple in terms of work steps, because it does not matter which of the sides of the triangle is placed against the side of the adjacent triangle.
    D In the embodiment of Figure 5, there is a right angle> between the base 2c and the first side 2a.
    In this case, a plate can be formed in which there is both an oblique structure and a perpendicular structure between the first surface and the second surface.
    A 30 In the embodiments of Figures 6 and 7, some of the profiles 2 are rectangular triangles according to the embodiment E of Figure 5 and some are equilateral triangles. o In the embodiment of Figure 6, all isosceles triangular profiles are mounted so that their base 2c forms the first surface of the plate 1.
    In the embodiment of Figure 7, again, the bases 2c of isosceles triangles form part of both the first surface of the plate 1 and its second surface N35.
    In the embodiment of Figure 8, the shape of the profiles 2 is the same as in the embodiment of Figure 3. However, in the embodiment of Figure 3, the plate 1 is formed by fitting the catheters of the triangles against each other. In the embodiment of the slot 8, instead, the hypotenuse of the triangle forms its first side 2a placed against the hypotenuse of the adjacent triangle and its second side 2b is formed by a catheter placed on the other side against the catheter of the adjacent triangle.
    Figure 9 illustrates the mechanical connection of the profiles to each other. Mechanical connection can take place, for example, using form locking. Figure 9 shows an example of a form lock with a dovetail joint.
    According to one embodiment, more than 55% of the surface area of the outer surface of the profile 2 is against the adjacent profile 2. According to another embodiment, more than 60% of the surface area of the outer surface of the profile 2 is against the adjacent profile 2.
    It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments - are thus not limited to the examples described above but may vary within the scope of the claims.
