Description

{Correcting Device for Deformation of Block}

The present invention relates to a block deformation correcting apparatus, and more particularly, to a deformation correcting apparatus capable of minimizing or correcting welding deformation of a block during welding.

The hull blocks 10, welded and assembled in block units in the ship drying process, are formed by vertically and horizontally joining a plurality of beams 5 as shown in FIG.

These beams 5 and blocks 10 are mostly joined by welding, which may result in weld deformation of the block and beam in a concave-convex shape due to thermal deformation by welding heat.

Generally, to compensate for such welding deformation, the workpiece can be straightened and the assembly can be continued by correcting the welding deformation.

However, even if the uneven deformation of each beam 5 may disappear, the block 10 after completion of the waving operation may become much more shrunk in the direction of the weld line of each beam 5, Likewise, the lower portion of the neutral axis n of the beam 5 may be contracted and warped as a whole.

3, the upper part of the neutral axis n of the beam 5 is subjected to a triangular heating process, as shown in FIG. 3, (7) method so as to correct the deformation.

However, this process has the following problems.

First, when the block work is carried out outside the factory, the work must be started after installing the gas line and the water-cooled hose line, which are necessary for heating, to the preceding drying position, and the work load is high.

Second, the block work is expensive because it requires a high-level expert who has accumulated a lot of experience, and it takes a lot of work cost and can not input an expert to other work.

Thirdly, if the preceding painting is done, the painting part is damaged due to the triangular heating (7) by the working work, therefore, a re-painting work is required.

Fourth, there is a problem that the steel structure may be denatured by heating and cooling even before the preceding painting.

Fifth, in the case of a work using heat, the portion of the work where the heat is applied reaches a tensile yielding condition. If the work is partially performed only by triangular heating, it may cause structural problems such as buckling and the like If the heating area is widened in order to avoid such a problem, the working efficiency is extremely deteriorated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a block deformation correcting apparatus which minimizes thermal deformation even during welding and does not require a smooth operation.

The problems of the present application are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a method of manufacturing a plasma display panel, including: forming a first block including a flange and a web; A wire exerting a tensile force on the first plate; And a wire coupling portion coupled to one surface of the first plate and coupled to an end of the wire.

And a pair of second plates coupled to the surface of the first plate coupled with the web and extending from the first plate toward the longitudinal center of the first flange and spaced from each other.

An end portion of the first plate facing the outer side may be formed to be inclined so as to form an angle of refraction.

The end of the flange being formed at a position retreated from the end of the web by a predetermined length and the end of the first plate being aligned with the end of the web, And may correspond to a distance between an end of the first flange and an end of the web.

Since the work by the welding work can be solved by a method other than heating, it is possible to solve the problem of painting and deformation of the work by heating, and it is possible to work even if it is not a skilled worker.

Also, since the stiffness of the beam is increased by the tensile force of the block deformation correcting device, the beam size can be reduced, and the overall weight can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In describing the present embodiment, the same designations and the same reference numerals are used for the same components, and further description thereof will be omitted.

The block deformation correcting apparatus according to the present embodiment will be described by taking an example that it is installed in a beam. In this embodiment, the beam 100 may include a web 110 and a first flange 120, as shown in FIG.

The web 110 may be formed to have a longitudinal direction in one direction. As shown in Fig. 4, a rectangular member having a longitudinal direction in one direction may be formed in a width direction.

The first flange 120 has a longitudinal direction similar to that of the web 110 and is coupled to be perpendicular to the top surface of the web 110 and may have a width greater than the thickness of the web 110 .

At this time, the first flange 120 may be formed at a position where both ends of the web 110 are retracted a predetermined distance inward from both ends of the web 110. That is, the first flange 120 may be shorter than the web 110.

That is, the web 110 and the first flange 120 may have a T-shaped cross section.

A second flange (not shown) having a shape similar to that of the first flange 120 may be formed on the lower side of the web 110. However, in the present embodiment, only the first flange 120 is formed . That is, the present invention is not limited by the shape of the beam 100.

On the other hand, the block deformation correcting apparatus of the present invention may include a wire fixing hole 130 and a wire 140.

The wire fixture 130 may be coupled to the upper surface of the web 110 and the side surface of the first flange 120 such that the first flange 120 is shorter than the web 110, .

Accordingly, the wire fixing holes 130 may be provided at both ends of the web 110 and the first flange 120, respectively.

The wire 140 is coupled to both the wire fixing hole 130 and the web 110 and the first flange 120 on which the wire fixing hole 130 and the wire fixing hole 130 are installed, .

The wire fixing part 130 may include a first plate 132, a wire coupling part 134, and a second plate 136, as shown in FIGS. 5 and 6.

The first plate 132 is coupled such that the first flange 120 is shorter than the web 110 to be perpendicular to the exposed portion of the web 110.

The length a of the first plate 132 may correspond to the distance a between the end of the first flange 120 and the end of the web 110.

Thus, the end of the first plate 132 and the end of the web 110 may be aligned.

The wire coupling portion 134 may be formed on the opposite side of the surface of the first plate 132 to which the web 110 is coupled, where the end of the wire 140 is coupled.

The wire coupling part 134 may extend from the first plate 132 toward the center longitudinal direction of the first flange 120 by a predetermined length. The rear end of the extended wire coupling portion 134 may be formed to be in contact with the upper surface of the first flange 120.

The second plate 136 is coupled to a surface of the first plate 132 that is coupled to the web 110 and a second plate 136 extending from the first plate 132 to the length of the first flange 120 &Quot; towards the center of the < / RTI > The rear end of the extended second plate 136 may be formed to contact the lower surface of the first flange 120.

At this time, the second plates 136 are separated from each other on the center line of the first plate 132, and the interval b may correspond to the thickness (b) of the web 110.

The upper surface of the web 110 is inserted into a portion of the wire fixing hole 130 where the second plate 136 is spaced apart from the wire fixing portion 130. The upper surface of the web 110 is inserted between the wire coupling portion 134 and the second plate, (Not shown).

At this time, the wire fixing holes 130 may be joined by a welding method.

The end portion 138 of the first plate 132 facing the end of the web 110 may be inclined to form an angle of refraction.

This is to form a weld improvement angle 139 when welded to another wire fixture 130, as shown in FIG.

In addition, the wire 140 may be provided with a turnbuckle 142 capable of adjusting tension. Of course, the turnbuckle 142 is not necessarily provided in the wire 140, and may be provided in the wire coupling part 134.

7, the wire fixing holes 130 are provided at both ends of the web 110. When the wire 140 is in a state of applying a tensile force to the wire fixing holes 130, Tensile force may be applied to the upper side of the neutral axis (n)

Accordingly, when the lower portion of the neutral axis of the beam is contracted and bent as in the prior art, it is possible to perform the work without heating it, and thereby, various effects can be exhibited.

A second plate 136 and a wire coupling portion 134 are connected and supported on the upper and lower sides of the first flange 120 so that a first plate 136 and a second plate 136 are interposed between the wire coupling portion 134 and the second plate 136, Since the flange 120 is inserted into the wire fixing hole 130, tensile force by the wire 140 is applied to the wire fixing hole 130, so that even if a moment is generated in the wire fixing hole 130, it can be effectively supported.

On the other hand, the tensile strength of the web 110 and the first flange 120 can be increased by the tensile force of the wire 140. Accordingly, the strength of the structure itself can be improved, and the height of the web 110 or the thickness of the web 110 or the first flange 120 can be designed to be thin as much as the strength contribution of the wire 140 The size and weight of the web 110 and the first flange 120 can be reduced.

8, when a tensile force is applied to the upper side of the neutral axis n of the web 110 by adjusting the tension of the wire 140, As described above, the deformation of the beam 100 can be corrected to correct deformation of the block.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. . Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and thus the present application is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
