Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal mesh and a method for manufacturing the same.

By the way, in this specification, up and down, left and right refer to directions based on the drawing, vertical refers to the upper and lower directions, and horizontal refers to the left and right directions, and these are all relative concepts.

A metal plate containing extruded aluminum is used as a material, and after forming a number of slots in a staggered arrangement in the longitudinal direction,
Metal mesh products, so-called expanded products, obtained by stretching and expanding in the width direction are known.

This net-like material has a large number of hexagonal-shaped meshes formed by vertical straight parts on both the left and right sides and a pair of left and right vertically inclined straight parts of equal length extending upwardly and downwardly in mutual directions from both the upper and lower ends of the mesh. However, they are arranged regularly in the vertical and horizontal directions, resembling a single hexagonal pattern. By the way, since the meshes mentioned above are regularly arranged, there is little variation, and these are used as fences, gates, etc.
Used as architectural members such as surface lattices, etc. 5. Sanskrit: ＾Me=
;} A metal mesh is desired, but since each mesh is obtained by enlarging the slots formed in the metal plate, it is possible to plasticize the material without creating cracks at the edges of the slots. There is a restriction that the hexagonal meshes must be deformed, and other than the regular arrangement of the hexagonal meshes, no other mesh shape or arrangement state has been realized.

This invention was made in view of the above circumstances.

Therefore, the hexagonal mesh A1 is formed by the two vertical straight portions 4 shorter than the vertical straight portion 2 and the four vertically inclined straight portions 3, respectively.

Then, the two meshes A1 are arranged on the left and right so that the straight portions 2 and 3 are in common and have a single hexagonal pattern, and the peripheral edge shape is a hexagonal shape that is symmetrical in the left and right as shown by the chain line. A central mesh group G is formed by arranging the meshes A2 above and below this. On the other hand, parallel vertical straight sections 5, 5 on both left and right sides arranged in a staggered manner in the vertical direction and upper and lower oblique straight sections 6, 6 connecting the upper and lower ends of these vertical straight sections 5, 5 are provided. Quadrilateral mesh Bn (n=1, 2
) is formed.

These parallelogram meshes Bn have their vertical straight portions 5 in common, and the hexagonal meshes Al, A
2 and the inclined straight line parts 3 and 6 are arranged in common along the inclined edge of the central mesh group G, two of each are arranged,
An outer mesh group H is configured. Furthermore, the central mesh group G and the outer mesh group H constitute a unit mesh group E whose peripheral edge shape is approximately hexagonal, and a large number of these unit mesh groups E are arranged in a connected pattern with the outer mesh group H in common. By doing so, a metal net-like object 1 is formed.

This example is a case where N=2 and M=1.

Therefore, the central mesh group G is N2 (N squared) = 4 hexagonal meshes Al, A2, and the outer mesh group H is N2 (N squared).
XM (product of N2:M) = 2 parallelogram meshes Bn
Each of them is composed of: Incidentally, on the vertical edge of each mesh group unit E, the linear sections 2 and 5 and their extensions are connected to form a block linear section D. Next, a method for manufacturing the metal mesh 1 will be explained.

Referring to FIGS. 2 and 3, a cross-sectional shape having an uneven shape is made up of a large number of parallel flanges 12 extending in the vertical direction and spaced apart from each other, and a web 13 connecting adjacent flanges at the middle of the dog's width. The material is an extruded aluminum plate cut into a predetermined length. And web 13
By forming a large number of vertically elongated slots in the section, a large number of unit slot groups e consisting of a central slot group g and outer slot groups h located around the central slot group g are created.
The central slot group g is formed by forming two slots Al, al in the left and right webs 13 with one web 13 in between, and two slots A2, a, vertically in the sandwiched web 13, in a staggered arrangement. Created by

Slot A is connected to the upper and lower ends of both slots Al and al.
The lower or upper end portions of , are sandwiched and overlapped in the left and right direction as shown by S. Further, the line connecting the upper and lower edges of each slot Al, a has a flat hexagonal shape that is vertically and horizontally symmetrical, as shown by the chain line. The outer slot group h has two slots B each.
n along the inclined sides of the flat hexagon, each slot b
1 and B2 so that the upper and lower ends overlap in the left-right direction (indicated by V), and the upper and lower ends of each slot Bl, b2 and Al, a2.
The lower end portions are formed so as to overlap in the left-right direction (indicated by UlU2).

The slot B2 is formed on the same web 13 as the slot a1, and the slot b1 is formed on the web 13 outside this web 13. Slot processing is carried out by forming the central slot groups g in a staggered arrangement on the material, and by creating a large number of unit slot groups e such that the outer slot groups h located around these central slot groups g are common. A preformed material 11 is produced.

Next, if this profile 11 is expanded by pulling it in the left-right direction along its entire length with a force greater than the deformation yield point of the flange 12, the flange 12 will be bent at the upper and lower edges of each slot a1 to B2, Slot Al, a2 is mesh Al, A2
Thus, the central slot group g forms the central mesh group G, the slots Bn form the mesh Bn, and the outer slot group h forms the outer mesh group H, and a unit composed of these slot groups G and h is formed. A metal mesh 1 is obtained in which unit mesh groups E are formed by the slot groups e, and each unit mesh group E is arranged in a connected pattern with the outer slot group H in common.

Here, the flange portion sandwiched by the overlapping portion S of the slots a1 and A2 becomes the common inclined linear portion 3 of the meshes A1 and A2, and similarly the flange portion sandwiched by the overlapped portion V becomes the mesh Bn. The flange portion sandwiched between the overlapping portions Ul and U2 is the mesh Al,
This becomes a common inclined straight portion 6 (or 3) between A2 and the mesh BO. In addition, the flange parts other than the above are the vertical straight parts 2, 4,
5, and furthermore, the remaining portion d where no slots are formed between the slot group units e becomes a lumpy straight portion D as it is. The placement of each slot above on the material is as follows:
Most preferably, a model of the mesh 1 to be manufactured is first drawn and the length and position of each slot are determined based on this.

FIG. 4 shows another embodiment.

This is the case when N=2 and M=3. The central mesh group G includes four hexagonal meshes A with different lengths of the vertical straight portions 2 and 4.
1 and A2, but here the vertical straight line portion 4 is longer than the vertical straight line portion 2.

Therefore, as shown by the chain line, the shape of the peripheral edge of the central mesh group G is such that the sloped edges are uneven and the vertical edges are very short. shall be included in the phrase ``approximately hexagonal or diamond-shaped with horizontal and vertical symmetry.'' The outer mesh group H is composed of NXM=6 parallelogram meshes B-(n=1,
2, m=1, 2, 3), and these meshes Brlrrl are arranged in two rows 3 along each inclined edge of the central mesh group G.
It is arranged in tiers. Here the mesh BruTl
n represents the number of columns, and m represents the number of stages. In this embodiment, the lengths of the vertical straight portions 5, 7, and 8 forming the parallelogram mesh Brlrrl are the same as those of the first and second rows in the first row.
In the second row and the third stage, the length is different for each stage, and becomes shorter toward the top and bottom and outward. Items of the same length are indicated by the same reference numerals. Therefore, these vertical straight portions 5, 7, 8 are partially common to those in the adjacent rows.The inclined straight portions 6 in each row are common to the adjacent meshes B.lnl, and are equally The one-stage parallelogram mesh BOl has hexagonal meshes Al, A2 and their inclined straight parts 6, 3 in common.This metal mesh 21 is manufactured in the same manner as the mesh 1 described above, but the outer shell is The slot group h is formed corresponding to the outer mesh group H of two rows and three stages.

Referring to FIG. 5, the outer slot group h is formed by forming six slots bl in two rows of three slots diagonally upward and downward from the periphery of the central slot group g to the left and right. At this time, the lengths of the slots in each row are different, and the size of the vertical slot interval V2 between each row is also different. This is because the lengths of the vertical straight portions 5, 7, and 8 of the mesh Brlrrl are changed for each stage. Also,
The slots Bnl, Bn2, and bn3 in each row are arranged so that their upper and lower ends overlap in the left-right direction (indicated by T).
The flange portion sandwiched between the overlapping portion molecules becomes the inclined straight portion 6. Furthermore, the slots Blm. which should be the meshes Blm and B2m on the same level. The upper and lower ends of b2m also overlap slightly in the left and right direction (indicated by V1), and the flange part sandwiched between this part V1 and the flange part at the above-mentioned interval V2 are the vertical straight parts of each mesh B-. 5, 7, and 8, which are partially common to the adjacent meshes. If such a slotted profile 22 is pulled and expanded in the left-right direction, a metal mesh 21 will be obtained. FIG. 6 shows still another embodiment, in which N=4 and M:3. The central mesh group G is composed of N2=16 hexagonal meshes A that are completely identical in shape, and the peripheral edge shape thereof is approximately rhombic.

The outer mesh group H consists of completely identical NXM: 12 parallelogram-shaped meshes Brlnl (n=1, 2, 3, 4, m= 1, 2
, 3), which are arranged in four rows and three stages along each inclined edge of the central mesh group G. These mesh groups H and G constitute a mesh group unit E, and a required number of these mesh group units are arranged in a connected pattern to form the metal net-like object 23. Metal net-like objects 1 and 21 in the above three embodiments
, 23 according to the present invention has at least one unit mesh group consisting of a central mesh group and outer mesh groups located above and below the central mesh group, the central mesh group comprising: N2 pieces (N is an integer of 2 or more) formed by the left and right kamedo sickle portions and a pair of left and right vertically inclined linear portions extending upward and downward in mutual directions from the upper and lower ends of these vertical linear portions. ), each of which has one straight line in common with other hexagonal meshes adjacent to it vertically and horizontally, forming a connecting pattern, and whose peripheral edge shape is roughly hexagonal or diamond-shaped with horizontal and vertical symmetry. The outer mesh group is formed by vertical straight sections on both left and right sides arranged staggered in the vertical direction and vertical straight sections connecting the upper and lower ends of these vertical straight sections. NXM
(M is a positive integer) parallelogram-shaped meshes, each of which has at least a part of one straight line in common with other parallelogram-shaped meshes adjacent vertically and horizontally, and It should be understood that the metal meshes are arranged in N rows and M stages along the inclined edge of the central mesh group, sharing one straight line part in common with the hexagonal meshes on the outside. The figure shows a slotted profile 24 used for manufacturing a metal mesh 23, with a central slot group g consisting of 16 slots a corresponding to the hexagonal mesh A of the mesh 23, and a central slot group g consisting of 16 slots a corresponding to the hexagonal mesh A of the mesh 23. The outer slot group h is made up of a total of 12 slots Brlnl formed in 4 rows of 3 slots, and by pulling and enlarging this in the left-right direction, the above-mentioned net-like material 23 can be easily manufactured. You'll understand.

To summarize, the method for manufacturing the metal net-like article described above consists of using a metal plate as a material, creating a unit slot group consisting of a central slot group and an outer slot group located around the central slot group on this metal plate. , is a method of stretching and expanding the entire material, in which the central slot group has N2 slots (N is an integer of 2 or more) arranged in a staggered manner and connects the upper and lower edges of the outermost slots. Created by forming the wire into a flat roughly hexagonal or diamond shape,
The outer slot group has NXM slots (M is a positive integer) in N rows diagonally upward and downward to the left and right, and the upper and lower ends of the slots in each row are connected to the central slot group. This can be said to be a manufacturing method in which the outermost slot and the adjacent slot are formed so that their upper and lower ends overlap in the left-right direction.
Therefore, in the above description, slots are formed for each web of the aluminum extrusion material, but slots may be formed for each unit of a plurality of flange strips. At this time, the straight portions forming each mesh are constituted by a plurality of flanges. Further, although the material is an extruded aluminum material in which webs and flanges are alternately connected, the material may be formed into a flat plate, and not only aluminum but also iron, copper, etc. can be used. As explained in detail above, this invention
This is completely different from conventional metal meshes in which hexagonal meshes are arranged regularly in the vertical and horizontal directions, and a plurality of hexagonal meshes and parallelogram meshes are combined to provide a highly varied meshwork. .

When this is used as architectural members such as fences, gates, and lattices, highly decorative buildings can be obtained. Furthermore, since the hexagonal mesh and the parallelogram mesh are arranged in a laid-down position, cracks will not occur at the slot edge edges when the slot is made in the material and expanded by pulling. It is also extremely easy to manufacture. Furthermore, if an arbitrary line is drawn horizontally on a net-like material, each mesh can be arranged so that the vertical straight part of each mesh is always on this line, so the bending strength is almost uniform and large. .
