[0001]
[Industrial application fields]
The present invention relates to a lining plate provided with a block plug material and a method for manufacturing the same.
[0002]
[Prior art]
As shown in FIG. 5, the lining plate 1 is conventionally lifted by lifting the lining plate 1 on the upper surface of the end portion of the lining plate 1 in order to lift the lining plate 1 during transportation and installation. A hole 7 is provided.
For this reason, while the lining plate 1 is used after being installed, water such as rainwater, earth and sand is transferred from the lifting hole 7 to the inner cavity 6 formed by the upper and lower flanges 3, 3, the web 4 and the side plate 16. , Muddy water, or similar solids, liquid mixtures, and the like enter. As a result, the lumen 6 of the lining plate 1 is corroded, and the strength and the like of the lining plate 1 are lost.
Therefore, a steel partition plate 15 is attached to the lining plate 1 in order to prevent intruded water or the like from entering further into the lining plate 1.
The partition plate 15 is attached to the inner side of the H-section steel 2 and the end portion of the side plate 16 by the entire circumference welding 18. After the partition plate 15 is attached, the end side plate 17 manufactured as a separate part is attached to the flange 3 and the side plate 16 of the H-section steel 2 by welding. The end plate 17 is provided with a discharge port 19 for discharging water or the like that has entered from the lifting hole 7.
[0003]
[Problems to be solved by the invention]
As described above, the measure for preventing intrusion of water or the like has a problem that the steel partition plate 15 is attached by welding all around, so that the number of parts is increased, requiring much labor, and high cost is inevitable. .
In addition, the dimensions of the H-section steel 2 that is the material of the lining plate 1, that is, the web height, the flange width, and the thickness thereof have manufacturing errors. For example, according to the JIS standard, the flange height is less than 400 mm. In this case, when the tolerance is ± 2.0 mm and the flange width is 100 mm or more and less than 200, it is ± 2.5 mm. In addition to such an error, it occurs due to shape deformation such as perpendicularity at which the flange 3 and the web 4 intersect. There is a dimensional error. For this reason, even if it is with respect to the H-section steel 2 of the same nominal dimension, actually, the partition plate 15 is appropriately applied to the lining plate 1 by dealing with the H-section steel 2 having different dimensions as a raw material, and There is a problem that it is necessary to prepare in advance several types of partition plates 15 having different dimensions in order to perform rapid assembly and welding work.
Further, since the partition plate 15 is fixed and attached to the lining plate 1 by welding 18, after the lining plate 1 is manufactured, the inside of the lining plate 1 sealed by the partition plate 15 is looked into. In the long-term use, water may penetrate into the inside due to cracks in the welded part. However, since the inside cannot be inspected or inspected, the quality of the lining plate 1 against long-term corrosion A problem also arises in terms of warranty.
[0004]
The present invention solves such problems, eliminates the work complexity and cost caused by using conventional partition plates, and covers even when the lining plate is manufactured and used, when necessary. A block that enables inspection and inspection of the internal condition of the work board, maintains the quality assurance of the cover board, and reliably prevents water entering from the lifting hole of the cover board from entering the interior. An object of the present invention is to provide a lining plate provided with a plug material and a method for manufacturing the lining plate.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a lining plate provided with the block plug material of the present invention has an H-shaped portion formed by an upper and lower flange, web, and side plate of H-shaped steel outside the lining plate. It is configured by mounting a block plug material in the vicinity of the inside of the H-shaped steel in the longitudinal direction with respect to the lifting hole of the cover plate provided at the longitudinal end of the upper and outer flanges of the steel.
Here, the block plug material can be composed of a main body of the plug material and a watertight holding portion provided in the periphery in contact with the lumen portion. The reason for providing the watertight holding portion is to make it possible to more effectively cope with dimensional errors and deformation of the H-section steel. As the block plug material, a rubber material, a foam material, a plastic material, or the like can be used.
Further, the watertight holding portion can be composed of lip portions provided in a plurality of rows in the depth direction of the block plug material and a sealing material interposed between the lip portions.
A stopper for preventing the block plug material from moving inward can be provided in the lumen portion of the lining plate.
The end of the side plate of the lining plate can be provided with a block plug material insertion hole for inserting the block plug material into the lumen of the lining plate. The charging hole can serve as a discharge hole for water or the like that has entered from the lifting hole.
