しておく。First, a plurality of rectangular tubular reinforcing portions (12) extending in the up-and-down direction and a connecting wall portion that integrally connects adjacent rectangular tubular reinforcing portions (12) at an intermediate portion of their thickness ( A plate-shaped metal material (11) made of an aluminum extruded mold material consisting of 13) is prepared.
The rectangular tubular reinforcing part (12) is hollow with a vertical rectangular cross section, and the rectangular tubular reinforcing part (12) is expanded from the material (11).
It becomes the reinforcing portion (2) when the metal (1) is manufactured. Connecting wall
On both upper and lower surfaces of (13), two ridges (14) extending in the up-down direction parallel to the rectangular tubular reinforcing portion (12) are provided at predetermined intervals in the left-right direction. Then, between the ridges (14) between the connecting wall portions (13) between the adjacent rectangular tubular reinforcements (12) and between the ridges (14) and the rectangular tubular reinforcements (12), Multiple vertical slots (15) each with a certain vertical spacing
(16) (17) is formed and three rows of slots extending vertically are formed. Vertical slots (16) (17) on both left and right slot rows and vertical slots on the central slot row on each connecting wall (13)
It is staggered vertically from (15). Further, a horizontal slot (1) is provided between the middle portions of the lengths of the vertical slots (16) (17) of the slot rows on the left and right sides of each connecting wall (13).
8) is formed and the vertical slot (16) and the vertical slot (17) are connected.

る。After that, if this material (11) is stretched in the left-right direction over the entire length and expanded, the portions corresponding to the ridges (14) and (14) of each connecting wall portion (13) will be deformed and the left-right vertical straight line portion (4) will be deformed. , Upper inclined straight section
(5) and the lower inclined straight line portion (6), the vertical slot (15) of the central slot row is expanded to form a hexagonal mesh (3).
Then, the rectangular tubular reinforcing portion (12) becomes the reinforcing portion (2). Also,
The lateral slot (18) is also expanded vertically. Horizontal slot (1
If you do not form 8), when you stretch the material (10) by pulling it in the left-right direction, the upper slanted linear portions (5) and the lower slanted linear portions (6) that form the hexagonal mesh (3) are formed. The angle between them is smaller than that in the case where the lateral slots (18) are formed, and as a result, the distance between the adjacent reinforcing portions (2) is smaller.

容易に行ない得る。EFFECTS OF THE INVENTION According to the method of manufacturing an expanded metal according to the present invention, a plate-shaped metal material having reinforcing portions on both left and right edges is provided with three rows of vertical slots at predetermined intervals in the vertical direction. A plurality of sets are formed at predetermined intervals in the left-right direction as one set, and the vertical slots of the left and right side slot rows of each set and the vertical slots of the central slot row are arranged in a staggered manner in the vertical direction. Since the horizontal slots are formed between the middle portions of the lengths of the vertical slots of the slot row to connect the vertical slots, and finally the plate-shaped metal material is stretched in the left-right direction to be expanded. As compared with the conventional method for producing expanded metal, the width of pulling and expanding can be increased, and it is possible to produce a wide expanded metal. Further, in the expanded metal produced by the method of the present invention, the presence of the lateral slots formed in the material makes the shape more peculiar than the conventional one. Further, in the expanded metal manufactured by the method of the present invention, since the reinforcing portions are present on the left and right side edges, the frame process and the like can be easily performed by utilizing the reinforcing portions.
