Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a multi-type angle type steel material which is used for a support column, a horizontal beam of an assembly shelf, a frame of various other structures, and the like.

[Prior Art] L-shaped angle type steel materials are used for columns, beams and other frameworks of assembly shelves, but when conventional angle type steel materials are manufactured and processed for their respective purposes, There was a problem that was not applicable. For example, as shown in Japanese Utility Model Laid-Open Nos. 55-7470 and 47-24325, the columns of the assembling shelves are provided with a large number of rows of engaging holes such as pins or tacks at predetermined intervals on the left and right side plate surfaces of the L shape. Cut the cut pieces to a certain length with the same length, put the corners inside and fit the corners of the shelves into the corners, and fasten the pins such as pins or tacks to the locking holes. Since it is to be worn, the holes in the surface of the side plate are used only for attaching the shelf plate. Therefore, there is a problem in terms of manufacturing, management, and cost because it is necessary to prepare a large number of various things other than the support because it cannot be applied to other things.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems of the conventional technology. The purpose of the present invention is to make an angle-type steel material by a simple process to form a column or a horizontal column. It is intended to provide a universal type angle type steel material which can be used for a frame of a crosspiece and other various structures, and can be easily applied to various kinds of products and has an excellent appearance.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the angle type steel material in the present invention is an angle type steel having left and right side plates bent into an L shape, and the left and right side plate surfaces are full length. A round hole and a vertically elongated hole are arranged in a row at regular intervals, and a reference hole is arranged in a row at the same interval over the entire length with a pitch formed at the corner of the angle steel.

[Embodiment] FIG. 1 shows an angle type steel material in which the left and right widths W are formed to be the same width, and one side plate 1 is provided with a large number of round holes 3.3. The other side plate 2 is provided with vertically elongated holes 4.4 in the same row and at the same interval S.

Further, the corner portions 5 of the left and right side plates 1.2 are provided along the longitudinal direction with reference holes 6.6. .

4 to 14 are application lines using the above angle type steel materials.

In FIG. 4, a line is drawn from one reference hole 6 at a certain angle θ to the surface of one side plate 1 and the shaded portion is cut. Then, the side plate 2 on the other side corresponding to the center of the reference hole 6 can be bent, so when it is bent inward, when θ is 90 °, a right angle L-shaped frame material as shown in FIG. 5 is obtained. To be The angle of θ is 60
A frame material having a desired angle can be obtained by selecting an arbitrary angle such as ° or 120 °.

As shown in Fig. 6, the upper end of the angle type steel material is cut into V-shapes in the left and right side plates 1.2 around the reference hole 6, and the triangular pieces 1'.2 'are bent inward. As shown in Fig. 7, the end plates 7a. A strut closed with 7b is obtained. Similarly, if the lower end is also cut and bent inward, a column whose lower end is closed by an end plate is obtained.

When one upper piece of the side plate is cut as shown in FIG. 8 and the upper piece 1 ″ of the other side is bent inward, a pillar closed by the end plate 7c is obtained as shown in FIG.

Fig. 10 shows the upper piece 1a of the other side cut by cutting one upper piece of the side plate.
Is cut diagonally to form a mountain-shaped upper piece 1a ', which is bent inward, and at the same time, the shape steel material itself is bent from the corner portion 5 to an acute angle θ'from 90 °, as shown in Fig. 11. Thus, a modified column having a closed upper end can be obtained.

As shown in FIG. 12, the shape steel material is cut into a certain size, and the side plate 1 is cut along the V-shaped angle θ ″ around the central reference hole 6 and bent as shown in FIG. As shown in Fig. 14, this is fitted with holes 3 or 4 at the lower end of the column.
When the above are combined and stopped with screws or the like, the support column 9 with a base is obtained. The angle θ ″ of the V type can be arbitrarily selected such as 90 ° and 120 °.

Embodiment 2 As shown in FIG. 15, one side plate 1.2 is formed wider than the other side W ', and the side plate 1 has a vertically elongated hole along its longitudinal direction.
4.4 ... are arranged at a predetermined interval S, and on the other wide side plate 2, round holes 3 and vertically elongated holes 4 are alternately arranged along the longitudinal direction at the same interval S as described above in two left and right rows. Set up. Side plate 1.2
The corner portion 5 is provided with reference holes 6.6 ... Consisting of round holes at the same interval S along the longitudinal direction with a pitch of half the pitch of the holes 3.4 and the entire length.

As shown in Fig. 16, when the upper piece 1 ".2" of both side plates 1.2 is cut into a V shape and each is bent inward, a pillar whose upper end is closed by end plates 7d.7e is formed as shown in Fig. 17. can get.

As shown in FIG. 18, a pillar is obtained by cutting one upper side of the side plate and bending the other upper piece inward to close the end plate 7f.

End plate 7g.7h as shown in Fig. 19 depending on the V-shaped cut angle
It is also possible to obtain a deformed column having

As shown in Fig. 20, if the middle part of the side plate 1.2 of angle type steel is cut into a V-shape at a certain angle θ and the steel is bent inward so that the V-shape matches, a frame with an angle according to the angle θ The material is obtained.

[Operation] When cutting or bending the end portion or the middle portion of the side plate, the reference hole 6 is used as the center. Further, when the angle of the corner portion is widened or bent into an acute angle, since the reference holes 6 are arranged in a row at a predetermined interval S, the reference holes are guided by bending and bending force is small. .

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

By simply cutting and bending angle type steel,
It can be used for all kinds of applications such as stanchions, cross rails, and frames.

The reference holes in the corners can be used as the center for easy and quick cutting, bending, etc. processing, and one type of versatile angle steel can be standardized and mass-produced at low cost. .

The round hole and the vertically elongated hole on the left and right side plates, and the reference hole at the corner portion can be used as engaging holes for screws and bolts, and therefore have great utility value as an assembly shelf.
