JPH09155453A - Bender for lip channel - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily perform the execution without any troublesome operation such as welding, by providing a bender consisting of a loading table on which a lip channel is loaded and a fitting groove in which an opening end part of the lip channel can be fitted along the longitudinal direction. SOLUTION: A lip channel 8 is inserted in a fitting plate 2 from an opening end part along the longitudinal direction. A drill bit is inserted from a through hole 2a in the drill bit of the fitting plate 2, and a fitting hole 9 of a screw is made. A tread part 5 is stepped by the foot so as to be fixed, and an inclined plate 3 is manually bent approximately at right angle. The end part of the lip channel 8 is bent to form a joining piece having the fitting hole 9 of the screw. The bending work can be easily and rapidly performed, and at the same time, the joining piece can be manufactured in a standardized manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used for joining a lip groove type steel (commonly called C-type channel steel) to another member, particularly for joining the ends thereof. .

[0002]

2. Description of the Related Art A channel member made of lip grooved steel is widely used as an aggregate of a structure. Conventionally, the following method has been used to join other members to these members. That is, one is a method of directly welding with another member, and the other is a method of screwing.

[0003]

However, in the method of welding, it is necessary to prepare an apparatus for welding, and if other members are other than metal, they cannot be joined. Not only that, but the work becomes complicated. Further, in the method of screwing, particularly when they are arranged in orthogonal postures to each other, it is necessary to fixedly connect to the end of the channel through an L-shaped metal fitting called “angle cat”. It was a laborious task.
In view of the above problems of the prior art, the present invention, when joining the lip groove type rope end portion and other members, without performing a complicated work such as welding, and without using a separate connecting member, It is an object of the present invention to provide a bender made of lip groove type steel that can be installed extremely easily.

[0004]

Therefore, in the present invention, a bender of lip groove type steel is basically provided with a mounting table on which the lip groove type steel is mounted, and the lip groove provided on the mounting table. The open end of the shape steel is configured with a fitting groove that can be fitted along the longitudinal direction thereof.

Then, in practice, it is fixed on the mounting table with a gap having a length substantially the same as the thickness of the lip groove type steel, and
The lip groove section steel is composed of a fitting plate provided so as to be fitted along the longitudinal direction of the opening.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a lip groove type steel bending device according to the present invention, FIG. 2 is a plan view of FIG. 1, FIGS. 3 (a) and 3 (b) are side views showing a method of using the bending device, FIG. FIG. 6 is a perspective view showing a bent portion of lip groove type steel.

As shown in FIGS. 1 to 3, the folding device in the present embodiment comprises a mounting table 1 and a fitting plate 2 which is welded and fixed onto the mounting table 1. Table 1
Is formed by bending a flat long metal plate to form an inclined plate portion 3 and a standing plate portion 4, and forming a step plate portion 5 extending horizontally from the lower end of the standing plate portion 4. There is. A gap 6 into which the open end of the lip groove type steel can be inserted is formed in the bottom surface of the fitting plate 2 (joint surface with the inclined plate portion 3). The gap 6 has a width substantially the same as the plate thickness of the lip groove type steel and is formed with a depth corresponding to the desired bending margin of the lip groove type steel end portion.

Further, the fitting plate 2 has a lip groove type steel (hereinafter,
Steel material) is provided with a through hole 2a for a drill blade for drilling a screw, and the inclined plate portion 3 has an oval through hole at a position facing the through hole 2a for the drill blade. Three
a is drilled. This through hole 3a is a through hole 2a in the steel material.
It is preferable to form the steel material to a relatively large size in order to prevent the steel material after processing from coming off from the gap 6 due to the burr that occurs when the steel is opened. Incidentally, reference numeral 7 in the drawing denotes a receiving plate for the drill blade.

Next, a method of working the lip groove type steel with the bender configured as described above to form a joint with another channel member will be described. First, as shown by the solid line in FIG. 3, the lip groove type steel 8 to be processed is inserted into the fitting plate 2 from the opening end thereof along the length direction. Then, a drill blade is inserted from the insertion hole 2a of the drill blade of the fitting plate 2 to drill a screw mounting hole 9, and the foot plate portion 5 is stepped on with a foot as shown by a chain double-dashed line in FIG. Fix it and push it manually until it becomes almost perpendicular to the inclined plate 3. This allows
The end portion of the lip groove type steel 8 is bent in the state shown in FIG. 4, and a joining piece 8a having a screw mounting hole 9 is formed. As described above, when the folding device of the present invention is used, not only the bending work of the lip groove type steel 8 can be performed easily and quickly, but also the joining piece 8a can be standardized and manufactured. The workability of the entire construction using the channel steel 8 becomes extremely good. Moreover, since the steel body and the joint are integrally formed, a very strong joint can be obtained.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, when joining the lip groove type steel end portion and other members, there is no need for complicated work such as welding, and no separate connecting member is used. There is an excellent effect that the construction can be performed extremely easily.
