Description

lamellar material METHOD FOR THEIR PRODUCTION AND ROLLS FOR USE IN THE METHOD Full Description BACKGROUND The present invention Gay relates in one respect to a laminate material of the type; hereinafter designated by the specified type; It includes a group of rows of ridges located on both surface kidneys so that each ridge is formed by photodistortion of the lamellar material so that it makes a corresponding depression on the opposite surface of the material. The laminate material is of the specified type, Lal, from the planar laminate material from which it is formed and the mass of the material required for a particular task can be reduced by the use of the laminate material of the specified type, Yay, of the planar laminate material. . An example of a laminate material of the specified variety is described in Chinese Patent No. 0 011-486.281. In this example; stretch; Direction oJ are rows of alternating bumps and depressions and straight lines can be drawn on a surface of the material between adjacent rows of such rows. The protrusions and depressions also form rows extending in a second direction perpendicular to the first direction, between which additional straight lines can be drawn on the surface of the material. And along: these straight lines; The total thickness of the material shall be substantially equal to the thickness of the 0 flat lamellar material from which the material of the specified type is formed and the material may be bent along these lines much more easily than it can be bent along the centerline of a row. as well as for the material described in this published specification; The total thickness of the laminate material of the specified type is about 11 times the thickness at a point where the thickness has a maximum value. This thickness is called in this statement the standard thickness of the material 0 (gauge of the material) 0 £YA.

. An alternative formulation material is described in UK Patent No. GB 20113138 as Van Leer. It is stated that this construction element can be made of: concrete; steel plate; hl: or synthetic resin and that the manufacturing process may include cutting or deep drawing. The structural element includes rows of buttresses on both surfaces, as well as rows of gaps between the rows of ridges. The total thickness of the mounting element is several times the standard thickness of the material from which it is formed. LS, used in this statement “Jody” The term 'sheet material' Generally flat material as described in the aforementioned Swiss patent specification af Products manufactured by bending generally flat sheet material; examples of such products are described In the UK Patent International Gig PCT Application Published in the Name of Applicant No. PCT/GB81/00095 General Description of the Invention 0 We supply according to Jf facet of the invention; a laminate material of the specified kind in which the relative positions of the protrusions and depressions such that the lines drawn on the surface of the material between adjacent rows 1 of the ridges and depressions are not straight.The total thickness of the laminate material (Ey of the invention as seen from any cross-section located in a plane perpendicular to the laminate material Gages is substantially greater than The standard thickness of the material, in contrast to the laminate material described in the Chinese patent No. “CH-486.281”, where the total thickness of the material in some planes that are perpendicular to the laminate material is generally essentially equal to the standard thickness. In all these cross-sections; The Gy laminate material of the invention is corrugated and there is no Say position at which the material is cut along a straight line and the resulting cross-section of the material will be straight. The total thickness of the laminate material embodying the invention is determined by the height of the burrs on both surfaces of the material. The height of the ridges which is sufficient to ensure that vo lines drawn on a surface of the material lie between adjacent rows of ridges and depressions is not straight £YA

¢’ on the spacing of the ridges and depressions in the rows. It was found that the total thickness, which is twice the standard thickness of the laminated material, is an appropriate and sufficient thickness to avoid the presence of straight lines on the surface of the material. It is preferable that the total thickness does not exceed four times the standard thickness of the material. It is best that the total thickness does not exceed three times the standard thickness 0 of the material. and by setting the total thickness of the material to a value sufficiently large to avoid straight lines on both surfaces of the material; It was found that a significant reduction in the overall length of the lamellar material could be avoided during the formation of bumps. It will be understood that the length of the lamellar material: tends to decrease when ridges are formed along the entire surface of the material: substantially lamellar. In the example described in Chinese Patent No. (CH-486.281) there will be a significant decrease in the length of the laminate material when burrs are formed to increase the total thickness (Jalal GE) of approximately 11. Although the resulting laminate material (Lal) will be However, the weight of the laminate material per unit surface area will be greater than 0 and the bumps on each surface of the laminate material described in Chinese Patent No. CH-486.281 are correlative and this property improves the value of the weight per unit surface area surface area. lamellar according to the present invention; the distance between the vertices of adjacent ridges on each surface of the material preferably exceeds three times the distance of each such vertex Lalla in the same direction as said interlayer dimension. ; and the ridges on each surface of the material embodying the present invention may be allocated to a variety of rows For example rows that extend along the material Rows that extend across the material in a straight line and rows that extend across the material diagonally relative to the length of the material In the row that has the smallest spacing the spacing (called in this statement the smallest spacing) is preferably in the range of 1 mm to © mm. It is also desirable that the spacing ve be smaller in the range from four to ten times the standard thickness of the material. Found to perform £YA

smaller spacing of about six times the standard thickness of the material; in Alla the total thickness is about twice the standard thickness; to avoid the presence of straight lines on both surfaces of the material and thus achieve a substantial improvement in the resistance (Dl) in comparison with the flat lamellar material from which the material embodying the invention is formed; Without a significant increase of A+ in the mass of the material per unit surface area. and in a case where stretched laminate material is used; It is preferable that each protrusion include a group of sides oriented in their own directions that are neither along the length of the material nor perpendicular to it. It is believed that this arrangement results in a better weight-to-resistance ratio than that resulting from the arrangement described in Chinese Patent No. 486.281-011; Where cil ga the bumps are directed in perpendicular directions along the material. In the preferred material embodying SAY (cp) the matrix of ridges on one surface of the material Silas is essentially the matrix of ridges on the opposite surface of the material. According to a second aspect of the invention; provide a method for producing a laminate material of the specified type wherein a set of “Glial” shall be provided on two rollers” and each tooth shall have four rolled sides and vo each side shall be oriented in a direction which is between an axial direction and a circumferential direction; The two rollers are installed so that they rotate relatively around their parallel axes, which are far from each other, a distance to ensure that the planes on one of the two rollers extend into gaps located between the gears on the rolling mill, os AY). Gy of the invention also furnishes a rolling pin comprising a set of gears on its outer surface 0©; Each tooth has four convoluted sides, each side oriented in a direction that lies between an axial direction and a circumferential direction.

The lamellar material shown in Figures 1 through ; In the drawings, it is made of metal and includes a large number of bumps and depressions on both surfaces, and each bump on one of the two surfaces corresponds to a depression on the other surface. The bumps and depressions that fall on one of the two surfaces are arranged in the form of straight rows in which the bumps and depressions alternate. One of these rows is indicated. which extends along the lamellar salad with reference number 801 and denoted CL © Row A of these rows is perpendicular to row 01 with reference number 11. There are rows 11 that have ridges only and are angled It is 45 for Rows 01 and 11 and there are Lad 1” rows that have depressions only and are sloped at an angle of © for Rows 0 and 1. Adjoining depressions and bumps are close enough together that there are no flat areas at all substantial amount of lamellar matter between them. ‎£YA | y

Vo is essentially flat and each depression has a base VE and each ridge has a vertex where the sides of Ly are inclined to at least the shape of a square 04 and each peak has a square shape 011 with an angle of ©; with respect to the length of the lamellar material. It is also for each base (VE) so that the sides are parallel to those vertices 3a 0 from each other by a distance that differs 5 188 in the direction 16 and adjacent vertices diverge but are at least twice as far apart as each vertex measured in the same direction and can reach more than four times that dimension. In Figure 0; Shows one of the two surfaces of the lamellar material. The opposite surface is essentially the same; where there is a corresponding matrix of ridges and recesses on the corresponding - © surface. It will be understood that a depression on the surface represented in the figure corresponds to a bump on the opposite surface. The foregoing description of burrs and recesses applies to 1 the burrs and recesses on both surfaces. The size of the vertices and other dimensions of the array on one surface are the same as those of the array on the other. ae Cross-section view of the lamellar material in a plane at the center of 1 shows the figure and as can be seen in Fig. 7; Material VT corrugated adjacent row 11 Row spacing 16 and 11 so that 11 laminar is in the plane midway between the two rows The total thickness of the material in this plane is substantially greater than the standard thickness of the material (p). A line drawn on both surfaces of the material in the cross-sectional plane shown in “© Figure 7” is not straight. In le oil, the ripples of the material appear more clearly in a plane that contains centers. The total thickness of the material at this oF level as shown in Figure 01. row is about twice the standard thickness of the material. in general; The total thickness does not exceed (0) four ay when the bumps and depressions form (Jade) times the standard thickness of the material and in the form of © £YA

A: The total thickness should not substantially exceed three times the standard thickness. and a post-treatment of the material may reduce the overall thickness to a certain extent. and “By the process shown 017 the laminate material shown in figures (ie) is formed from a roll (other than 117 in figure ;. In this process; The flat lamellar material, each containing a number of teeth, is pulled on NAVA and passed between a pair of 0 and 1 Ve rollers that hold its outer surface. Each tooth pushes a section of the laminated material into a gap between the notches on the surface of the other rolling to form a protrusion corresponding to that of the other rolling and a corresponding depression corresponding to the first rolling. Thus, the total thickness increases on the two surfaces. By forming the lamellar material passes between the rollers in pairs 09 and VA and from the pair of rollers and 74 that forms the lamellar material in the form of a channel rod. The other pair 77 YY with YO and 14 is managed by means of a joint management YY and pairs of rollers 77-19 and 18 of the rollers. The rollers are run at the same circumferential speed, YT, in a well-known form, and they include an electric motor, essentially, so that the lamellar material passes continuously and at the same speed between the two rollers.

YF 77 of the pairs of Yas Rollers and then between the Rollers in successive pairs. 19 and VA - Alternative means or means to modify the laminate material may be provided in another way. And after VE and use it. Loli] The modification of the shape of the lamellar material is completed; It can be cut into pieces of the same shape, and one of these two rolls is shown in Figure 19 and VA. The two rolls have a TY arrangement on their outer surface on a number of identical gears V4. This roll includes ov. Rolled with an angle of 46. Each tooth includes Yo in several spiral rows off-axis at an angle of £0 and Ye extends square in shape as the edges of the square off-axis YA header and 7? from each edge of the head. The adjacent sides meet at the edges of the TY Fe YE with a corresponding socket (AY) of the tooth. As can be seen in a direction extending from one of these edges to the edge of the side that lies between the two edges, a curved shape is formed. And it shall be for all aspects in all elderly women © M

same shape. It will be noted that the sides of the gears on the rollers point in directions that lie between the circumferential direction and the axial direction. In an alternate arrangement; Shown in Figure A the heads of the gears 4 in one direction inclined at an angle of 60 from axis 171 are longer than those of the other cil alan. And in this arrangement; The grooves in one of the groups of spiral grooves 0 » that lie between adjacent rows of serrations are closer to each other than the grooves in the other groups. The VY laminate material is held and stretched by the gears when it is passed between the two rollers VA and 19 so that the GS Js hl of the laminate material is reduced to a small degree only or not to a great extent. The decrease in total height (13 found) depends on several factors; Including the thickness of the laminate material and the increase in the total thickness which occurs by the two-rolled VA 18 preferably; should in all cases; The length of the laminate material, Le, shall not be reduced by more than 719 from the initial length. in general; The length of the sheet material leaving the two rolls 18 and 51 shall not be less than 900 of the length (AY) and it is preferable to keep the length of the sheet material in the range from 756 to 7001 of the initial length. Preferably the total thickness ve | of the lamellar material leaving the rolled VA and 91 should be between two and three times the standard thickness sal all lamellar. Post-treatment of the laminate material with VY YE YY pairs of rollers reduces the total thickness to a value of about twice the standard material thickness. : LS can be seen in the figure ©. The sides of the notches 77 meet those of the adjacent notches YY through the gaps YE whose width is at least the same as that of the VY thread at its base nor ©” - these VE slots are occupied by the PY threads on the VA roll and at The nipping area between the two rolls VA 5 VA enters the elderly?? To the gaps between the edges of: the YY threads so that the edges of each TY tooth face the edges of the adjacent threads YY and in the gaps FE the metal plate is not constrained to take a shape that is determined according to the forces exerted on the plate at the heads of the YY threads And??. These forces are applied such that the vo|lamina does not remain flat in the gaps YE EYA

And the separation distance between the heads of the adjacent threads is 717 times the distance of each of these heads Talia in the same direction at least. When rolling pins 18 and 51 have the shape shown in Figure (A), the elongated pins 0 on one of the rolling pins extend into the gaps “1” which lie between specific pairs of adjacent elongated pins 0 on the other rolling but not These gaps are fully occupied.Therefore, two relatively small sections of each long side of each tooth are usually directed towards the sections corresponding to the sides of a tooth on the other roller. This clearance is somewhat greater than the standard thickness of the laminated material to be processed by the rolling pins.The notches - on one of the two rollers - do not enter into the gaps 15 that are located between the short grooves of the adjacent notches on the other roller. The two rollers have 18 and 91 teeth that have a shape (lata) and each side is in the form of a twisted curve; as seen in a direction extending from the edge of the tooth on one of the borders of that side to the edge of the tooth on the opposite border of that side. The effect of each of the two rolls VA and 41 on the laminate material is considered Wiles to the effect of other rolling mills.The resulting lamellar material by the process shown in the figure is considered; suitable for use alone as a structural member; For example a pillar or a sill. For these purposes; Lamellar material in the form of a canal rod is particularly suitable; The ductal rod includes lips and a tendon that keeps the lips spaced a predetermined distance apart. “Jay©” - The surfaces of both the lips and chord are on rows of ridges and depressions. and in some cases; It may necessitate the presence of bumps and depressions only on a section of the surface of the laminate material. The invention can be applied particularly usefully to uprights used in upright and framing partitions and to channel rails having lower end portions and upper end portions of uprights.

/" For the purposes of (sal) a flat material in general or any material with a section other than the channel section is useful. An alternative to the pair of rollers 19 OVA may be represented by a pair of rollers; 0 each of which has the shape shown in Figure A or A pair of asymmetrical rollers, for example, one with square gear and the other with elongated gear The sheet material is preferably mild steel, which may be galvanized or otherwise coated to protect it from rust The adjustment to be made is left to the wrought steel plate Flat galvanized starting with the method described above Protective coating intact Lol The standard thickness of the flat sheet material is typically in the range from 0.7 mm to mm.
