[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ruler for cutting steel used when cutting steel.

[0002]

2. Description of the Related Art In order to form a structure by welding steel materials in combination, it is necessary to cut off portions where the steel materials overlap, as shown in FIG. Conventionally, a steel material cutting ruler as shown in FIG. 4 has been devised in order to efficiently perform the cutting operation of the channel steel.

[0003] That is, in FIG. 4, a cutting portion 12 corresponding to a steel material cutting line is provided at a corner in the long side direction of the horizontal plate 10, and a steel material locking member 14 is attached to a tip end of the cutting portion 12. This is a steel material cutting ruler which is formed by joining rectangular vertical plates 16 at right angles to the rear end and the short side surface 18 to form a single piece.

In order to use the ruler for cutting steel material, the ruler for cutting steel is superimposed on the channel steel 20, the locking member 14 is hooked on the end of the steel material, and the cutting machine is cut along the cutting portion 12 for cutting steel material. It cuts steel by running.

[0005]

However, the steel materials used for cutting are not always straight as sized but sometimes deformed or out of dimensional. Therefore, the conventional steel material cutting ruler may not be able to be perfectly fitted to the steel material.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional ruler for cutting steel materials. The ruler can be fitted to a slightly deformed steel material by slightly expanding and contracting the width of the ruler. It is an object of the present invention to provide a ruler for cutting steel material that can be used.

[0007]

According to the present invention, there is provided a ruler for cutting steel material, comprising a pair of angled members formed by joining a vertical plate and a horizontal plate at a right angle, and a pair of the vertical plate and the horizontal plate of the angled member. A ruler cutout provided on one side corresponding to the steel material cutting line, a connecting member attached to the upper surface of each horizontal plate for connecting the angled members symmetrically, and the connecting members And a bolt that is connected via a spring.

[0008]

A connecting member is mounted on the upper surface of each horizontal plate for connecting the chevron members symmetrically. Since these connecting members are joined by bolts via springs,
By slightly expanding and contracting the width of the ruler, it can be fitted to steel materials having slightly deformed and different dimensions. On the other hand, since the vertical plate and the horizontal plate are joined at right angles to each other, a ruler cutout is provided on one side of a pair of angled members integrated with each other so as to correspond to the steel material cutting line on the vertical plate and the horizontal plate. Then, the steel material is cut along the ruler cutout.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view in which a part of an embodiment of the present invention is cut away;
FIG. 2 is a plan view. The pair of chevron members 22 are formed by joining the vertical plate 16 and the horizontal plate 10 at right angles to be integrated,
On one side of the vertical plate 16 and the horizontal plate 10 of the angled member 22, there are provided ruler cutouts 12 provided respectively corresponding to the steel material cutting lines.

The connecting members 24 are mounted on the upper surfaces of the respective horizontal plates 10 for connecting the angled members 22 symmetrically, and two bolt insertion holes 26 penetrate therethrough. One side of the bolt insertion hole 26 has a size through which only the bolt 28 penetrates, while the other side has a large diameter so that the spring 30 that is fitted to the bolt 28 and interposed can be accommodated. Since the bolt 28 fitted in the bolt insertion hole 26 is urged by the spring 30, the connecting member 24 is tightened, and the two chevron members 22 are elastically connected symmetrically.

The magnet 3 is provided at an appropriate position on the inner surface of the horizontal plate 10.
2 is attached so that the angled member 22 and the steel material 20 are brought into close contact with each other. In addition, a handle 34 is attached to the connecting member 24 so as to be convenient for handling a ruler for cutting steel material. Further, a locking piece 36 hangs down from the tip of the chevron 24 where the cutout 12 is located, and is hooked to the end of the grooved steel 20 as necessary.

The operation of the steel cutting ruler according to the present embodiment will be described. When the steel cutting ruler is fitted to the deformed grooved steel material 20 or the grooved steel material 20 having a somewhat larger dimension, the pair of angled members 22 are formed. Since the connection member 24 is tightened by the bolt 28 via the spring 30, the gap between the chevron members 22 expands and contracts, and a gap is freely formed. Therefore, the ruler for cutting steel material can be accurately applied to the channel steel 20.

[0013]

As described in detail above, the ruler for cutting steel material according to the present invention has a pair of angled members formed by joining a vertical plate and a horizontal plate at right angles, and the vertical plate and the horizontal plate of the angled member. A ruler cutout provided on one side of the plate corresponding to the steel material cutting line, a connecting member attached to the upper surface of each horizontal plate for connecting the angled members symmetrically, and the connection It is characterized by comprising bolts that connect members together via a spring, and the connecting portion between the left and right chevron members expands and contracts freely, so that a deformed grooved steel material or a slightly larger grooved shape Even with steel, the steel cutting ruler can be accurately applied.
