Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for correcting misalignment of a section steel such as a T section steel.

[0002]

2. Description of the Related Art In hull structural members, bridges and other steel structures, a large number of shaped steels such as T-shaped steels are used as reinforcing members for steel plates.

[0003] The above-mentioned steel structure is often made of blocks, and the blocks are often welded to each other to complete a large-sized structure. In many cases, a so-called misalignment has occurred. The deformation due to the thermal strain of the steel plate, the deformation due to the thermal strain between the shaped steel plate and the steel plate, or the mounting error is caused by various combined effects, and a difference is generated.

Conventionally, these methods for correcting misalignment of shaped steel have been
It is shown in FIG. 5 (side sectional view). In FIG. 5, reference numerals 1 and 2 denote steel shapes joined to steel plates 10 and 11 by welding a and b, and the steel shapes 1 and 2 are flanges 1a and 2a and webs 1b and 2b.
Consists of 1c and 2c are welding grooves. In the case where there is a difference between the shaped steels 1 and 2 as shown in the figure, the L-shaped piece 12 is welded to the steel plate 10 of one block, and the steel plate 11 on the other side is welded.
A wedge 13 is driven in from the side with a hammer 14 to correct misalignment.

[0005]

However, the straightening method using the L-shaped piece 12 and the wedge 13 has the following problems. Since the L-shaped piece 12 is attached to the steel plate 10 by welding c, welding time is required. After the shape steels 1 and 2 are welded, it takes time to perform gas cutting and grinder finishing of the L-shaped piece 12. After the gas is cut off and removed from the L-shaped piece 12, a scratch may be generated on the steel plate 10, and it takes time to repair the scratch.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus for correcting a misalignment of a shaped steel which does not need to be welded to a block of a steel plate or the like and does not require labor such as gas cutting and grinder finishing.

[0007]

An object of the present invention is to provide an inverted C-shaped part which is provided so as to straddle a flange portion of a shaped steel which is disposed to face each other, and one of the inverted C-shaped parts has a side part. A first hook portion inclined in the web direction with respect to the flange surface, and a second hook portion bent below the flange portion of the section steel, and further, a flange of the section steel is provided on one side before and after the one inverted C-shaped portion. A width determining portion that abuts on a side surface is provided, and the inverted C-shaped portion and the inverted C-shaped portion and the width determining portion on the other side are aligned in the longitudinal direction of the shaped steel to correct misalignment of the shaped steel. Solved by the device.

According to the above-mentioned means, each of the inverted C-shaped portions is disposed so as to cover from above the flange portion of the shaped steel, with the welded portions of the shaped steel disposed opposite to each other as boundaries. When the wedge is driven between the first hook portion inclined in the web direction of the C-shaped portion and the flange of the shaped steel, the width determining portion abuts the flange side surface of the shaped steel, and the main body is fixed to one side of the shaped steel. You. In this state, by inserting another wedge between the shaped steel on the other side and the inverted C-shaped portion on the other side, the webs of the shaped steel can be aligned with the cores of the flange surfaces.

Further, since the inclined first hook portion is formed on the inverted C-shaped portion, the first hook portion is inserted into the shaped steel flange portion from an oblique direction, so that the setting is easy.

[0010]

FIG. 1 is a side view of an apparatus for correcting misalignment of shaped steel according to the present invention. Reference numerals 1 and 2 denote shaped steel such as T-shaped steel, which are straightening members arranged opposite to each other. 2a and webs 1b and 2b, 1c and 2c are welding grooves.

Reference numeral 3 denotes a base of the apparatus for correcting misalignment of a shaped steel according to the present invention, and reference numeral 4 denotes an inverted C-shaped portion attached to one side of the base 3, as shown in FIG. And is provided so as to cover the flange 1a of the shaped steel 1 by inverting the C-shape, and has side bodies 4a and 4b. In correcting the section steel 1, the section steel is straightened downward by driving a wedge 13a, and the section steel is corrected right and left by driving a wedge 13b.

Reference numerals 5 and 6 denote width determining portions provided on side portions of the base 3, and have hook portions 5a (6a) formed at lower portions as shown in FIG. 3 (cross section taken along the line B in FIG. 1).

An inverted C-shaped portion 7 is provided between the width determining portions 5 and 6, and the inverted C-shaped portion 7 has a first hook 7a and a second hook 7b, as shown in FIG. The first hook 7a is provided with an inclined portion 7c that is inclined with respect to the surface of the flange 2a. In addition, 8 is a handle.

The steel bars 1 and 2 are set on the flanges 1a and 2a of the steel bars 1 and 2 with the base body 3 tilted. The lower surfaces of the width determining portions 5, 6 and the inverted C-shaped portion 7 are brought into contact with each other,
In this state, a wedge 9 is driven into the inclined portion 7c of the hook 7b of the inverted C-shaped portion 7 and the corner of the flange 2a of the shaped steel 2.

The base 3 is fixed to the shaped steel 2 in a state of being supported at three points by the width determining portions 5 and 6 and the wedge 9 of the inverted C-shaped portion 7.

Thereafter, the inverted C formed at the end of the base 3
Wedges 13a and 13b are driven into the gap on the upper surface or the side surface of the flange 1a of the section steel 1 in the mold section 4, and the misalignment of the section steel 1 is corrected.

[0017]

According to the present invention, since only wedges are driven, the conventional work of removing the L-shaped piece, such as welding and gas cutting, and the repair of scratches do not occur.
