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.
If it is used as a building material such as a grid, the finished building will look dull and monotonous.

Therefore, there is a need for a metal mesh with a wide variety of variations, but each mesh is obtained by enlarging the slots formed in the shape of a metal plate. There is a constraint that the hexagonal meshes are plastically deformed, and other than the regular arrangement of the hexagonal meshes, no other mesh shape or arrangement state has been realized. The present invention has been made in view of the above-mentioned circumstances, and provides an easy-to-manufacture metal mesh material that is highly decorative, has high bending strength, and a method for manufacturing the same.

A detailed explanation will be given below with reference to the drawings.

In FIG. 1, parallel vertical straight portions 2, 2 on both left and right sides,
The center of the hexagonal shape is formed by six straight parts, including a pair of left and right upper inclined straight parts 3, 3 and lower inclined straight parts 3, 3 extending upward and downward from both the upper and lower ends of these vertical straight parts 2, 2. A mesh A is formed.

On the other hand, parallel vertical straight parts 4, 4 on both left and right sides arranged in a staggered manner in the vertical direction, and vertical straight parts 5, 5 with both vertical slopes connecting the upper and lower ends of these vertical straight parts 4, 4 are provided. A quadrilateral outer mesh B is formed. Then, this outer mesh B shares the inclined linear portion 5 with that of the central mesh A and is arranged above and below this mesh A, thereby forming a unit mesh group E whose peripheral edge shape is approximately hexagonal. has been done. The hexagonal horizontal connecting mesh Q adjacent to this unit mesh group E is also formed by left and right vertical straight portions 6, 6 and a pair of left and right vertically inclined straight portions 7, 7. In this embodiment, the unit mesh groups E and the horizontal linking meshes Q are arranged alternately in the left and right direction, and are horizontally linked to the vertical straight portions 4, 2, 4 on the vertical edges of the periphery of the unit mesh group E. The vertical straight portions 6 of the mesh Q are common to each other. Furthermore, in this embodiment, the mesh rows L, which are formed by alternately arranging the unit mesh groups E and the horizontal linking meshes Q in the left-right direction, are arranged in a plurality of vertical stages.

Between this mesh row L, there are also left and right vertical straight portions 8,
8 and a pair of left and right vertically inclined linear portions 9, 9, hexagonal vertical linking meshes R are arranged in the left-right direction with the vertical linear portion 8 in common, and the inclination of these meshes R is The straight line portion 9 and the inclined straight portions 5 and 7 of the parallelogram-shaped outer mesh B and lateral linkage mesh Q are common. Then, the vertical straight parts 4, 4 forming the outer mesh B are connected to the mesh R
are connected in a straight line with the vertical straight section 8 interposed between them. By connecting the connecting points of the left and right inclined straight parts 7, 7 with the vertical straight part 8, a unit mesh group E is created.
are linked in the vertical direction. The metal mesh 1 is constructed as described above. In addition, each unit mesh group E
The straight parts 2, 4, and 6 are connected to the vertical edges of the unit mesh group E, and the straight parts 8, 4, and their extensions are connected to the upper and lower connecting parts of the unit mesh group E, forming a block straight part. D is formed.

In the metal mesh 11 shown in FIG. 2, unit mesh groups E are arranged in the left-right direction every third horizontal linkage mesh Q.

In this way, the number of connected meshes Q for lateral linkage is arbitrary, and an appropriate number of unit mesh groups E may be arranged consecutively without meshes Q intervening. It is also possible to arrange the shape meshes B in multiple stages vertically.

Next, a method for manufacturing the metal mesh 1 will be explained.

Referring to FIGS. 3 and 4, a plate with an uneven cross section is made up of a large number of parallel flanges 22 extending in the vertical direction and spaced apart from each other, and a web 23 connecting adjacent flanges at their width intermediate portions. The material is an extruded aluminum material cut into a predetermined length. By forming a large number of vertically extending slots in the web portion 23, a slot row 1 consisting of a unit slot group e and a lateral linking slot q is created. The unit slot group e is
It is created by forming a central slot a and an outer slot group b such that the upper and lower ends thereof are sandwiched therebetween and the upper and lower ends overlap each other in the left-right direction (indicated by T).

Then, the unit slot group e and the horizontal linking slots q are arranged alternately in the left and right direction to form a slot row 1. The slot rows 1 are formed in a plurality of stages with required intervals vertically, and vertically connecting slots r are formed between each slot row 1. The vertical linkage slot r is formed so that its upper and lower ends are sandwiched between the unit slot group e and the horizontal linkage slot q, and overlap in the left-right direction (indicated by S). Through the above steps, the slotted shape material 21 is produced. Next, if this profile 21 is expanded by pulling it in the left-right direction over its entire length with a force greater than the deformation yield point of the flange 22, the flange 22 will be expanded above each slot A, b.
It is bent at the lower edge, slots A and b become meshes A and B, unit slot group e forms unit mesh group E, slot q forms mesh Q, slot r forms mesh R, and the mesh rows are formed. A metal net-like material 1 in which L is connected vertically in a plurality of stages is obtained.

Here, the overlapping part molecules of slots A and b become the common slope linear parts 3 and 5 of meshes A and B, and the overlap part S of slots r and b or q becomes the common slope of meshes R and meshes B or Q. This becomes the straight portion 9,5 or 9,7. Furthermore, the remaining portion d where no slots are formed between the upper and lower unit slot groups e and between the upper and lower slots r becomes a block-like straight portion D as it is. In order to arrange the slots on the material, it is most preferable to first draw a model of the mesh to be manufactured, and then determine the length and position of each slot based on this.

In the above description, slots are formed for each web of the aluminum extruded material, but slots may be formed for each unit of a plurality of flanges.

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. FIG. 5 shows yet another embodiment of the invention.

In this figure, a pair of left and right vertically inclined straight parts 33, 35
The central mesh group G is formed by four hexagonal meshes Al and A2 having the same length but different lengths in the vertical straight portions 32 and 34.
is configured. Two meshes A1 are arranged on the left and right, and two other meshes A2 are arranged above and below these, and each straight portion 32,
33 and 35 are commonly arranged in a single hexagonal pattern, and the peripheral edge shape is a hexagonal shape that is symmetrical in the left and right directions as shown by the chain line.

On the other hand, four equal parallelogram meshes Brlm
(n = 1, 2, m = 1, 2) constitutes an outer mesh group H, and these meshes B. Tn are arranged in two rows and two stages along each inclined edge of the central mesh group G.

Here mesh B. n in m represents the number of columns, and m represents the number of stages. These meshes B- have a common vertical straight portion 36 in each row and a common inclined straight portion 37 in each row, and further have a parallelogram-shaped mesh B- in the first stage.
n! is a hexagonal mesh Al, A2 and its inclined straight part 33,
35 and 37 are used in common. These central mesh group G and outer mesh group H constitute a unit mesh group E whose peripheral edge shape is approximately hexagonal, and this unit mesh group E is arranged in the left-right direction every second hexagonal lateral linkage mesh Q. A mesh horizontal row L is created, and the vertical straight portion 38 of the adjacent horizontal linking mesh Q and the vertical straight portions 32 and 36 on the vertical edges thereof are common.

In this embodiment, since the outer mesh group H is composed of two rows of meshes B-, in order to arrange a plurality of mesh rows L one above the other and connect them together, two horizontal rows of vertical linking meshes R are required. and,
An auxiliary mesh J arranged between these is required.

The auxiliary mesh J shares the inclined straight line portions 37, 41, 43 with the parallelogram-shaped mesh B22 and the vertical linkage mesh R, and the vertical linkage mesh R has the parallelogram-shaped mesh Bl2, the horizontal linkage mesh Q, and the auxiliary mesh. Mesh J and inclined straight parts 37, 39, 41, 4
3 in common. In the above, the central mesh group G is 4
It is composed of hexagonal meshes Al and A2,
This is a pattern in which N2 (N is an integer greater than or equal to 2) hexagonal meshes are connected in common with other hexagonal meshes adjacent to each other vertically, horizontally, and vertically, with one straight line in common, and the peripheral edge shape is symmetrical horizontally, vertically, and vertically. It is constructed by arranging them in a roughly hexagonal or rhombic shape.

The outer mesh group H includes 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 has a central mesh. N rows M along the inclined edge of the central mesh group, with the outermost hexagonal mesh of the group and one straight line part in common.
It is constructed by arranging it in stages. Here, the shape of the periphery of the central mesh group is "hexagonal or rhombic" because it may be rhombic depending on the length of the vertical straight part and the inclined straight part of each hexagonal mesh. In addition, even if the inclined edge of the peripheral edge is stepped, this peripheral edge shape is included in the above phrase. In addition, in the outer mesh group, "4x.j-, in which at least a part of one straight line part is common," means that when the length of the vertical straight part of the parallelogram mesh is changed every 5 stages, only part of it is common. This is because a situation may occur in which the metal mesh 31 shown in FIG.
It is manufactured by using an extruded aluminum material with an uneven cross section as a material, punching a number of slots in it, and then expanding it by stretching5.The slots can be formed to correspond to each mesh, so The manufacturing method will be easy to understand.

The central slot group corresponding to the central mesh group G has -y slots arranged in a staggered manner, and has a roughly hexagonal or rhombic shape with a flat line connecting the upper and lower edges of the outermost slots. The outer slot group corresponding to the outer mesh group H has NXM slots in N rows diagonally upward and downward on the left and right, and the upper and lower ends of the slots in each row. The outermost slot of the central slot group and the adjacent slot are formed so that their upper and lower ends overlap in the left-right direction. The central slot group and the outer slot group constitute a unit slot group, and the unit slot groups are arranged in the left-right direction every required number of lateral connection slots corresponding to the lateral connection mesh Q. As explained in detail above, the present invention is completely different from conventional metal meshes in which hexagonal meshes are arranged regularly in the vertical and horizontal directions, and in which one or more hexagonal meshes and parallelogram meshes are assembled. They are combined to form one unit mesh group, and this unit mesh group is further arranged in the left-right direction in combination with other hexagonal meshes, providing a highly varied network.

When this is used as architectural members such as fences, gates, and lattices, highly decorative buildings can be obtained. Moreover, since the hexagonal mesh and parallelogram mesh are optimally arranged, when a slot is formed in the material and the material is stretched and expanded, cracks do not occur at the edges of the slot, making it extremely easy to manufacture. It is. Additionally, if you draw an arbitrary line horizontally on a mesh, 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. ing.
