Description

Technical Field [0001] The present invention relates to a surface lining structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface lining structure and a construction method thereof, and more particularly, to a surface lining structure having excellent workability and economical efficiency because a lining structure can be constructed only by welding.

Generally, a water treatment facility formed of concrete such as a water tank for treatment of sewage and wastewater, a water channel, or a large capacity tank is used for waterproof defects such as cracks, cracks, foam ties, Without appropriate repair and waterproofing, the steel or concrete inside the concrete will corrode by water or chemicals penetrated through the defect.

Corroded reinforcing steel causes volume expansion, which further expands the cracks, causing the surface to peel or peel off. In this way, once damaged concrete is damaged, leakage of leaks and corrosion of reinforcing steel will be accelerated and the area of deterioration will be expanded so that the entire structure is structurally very vulnerable.

Therefore, a lining structure can be constructed on the outer wall of the concrete structure to enhance durability. Various methods such as waterproof coating method, polyethylene (PE) lining method, stainless steel (STS) lining method, ceramic coating lining method, or composite material lining method are known as a lining construction method.

Conventional lining structures or construction methods include a structure repair and reinforcement method using a titanium sheet of Patent No. 10-0976997, a lining material of No. 10-1086815 and a construction method using the same, a structure protection system of a water treatment facility, No. 10-1321743, a structure protection system for a water treatment facility, a waterproof lining structure for a concrete structure, and a construction method thereof are disclosed.

In the Japanese Patent Registration No. 10-1139969, the bent panels are joined to each other by bolts or welding, and then fixed to the wall with an anchor bolt formed at the center of each panel. Panels are first assembled by bolts or welds and then fixed with anchor bolts. It is not easy to move the huge assembly panel and tighten the anchor bolts by aligning a number of corresponding anchor bolt holes in each panel 1: 1 There is a problem that the workability is poor.

Japanese Patent Application No. 10-1321743 fixes a fixed channel to a structure with an anchor bolt, and joins the joining channel to the fixing channel by welding or bolt, and joins the panel to the joining channel with the joining bolt. Since all four sides of the square panel must be tightly bolted together, a coupling channel extending in both the vertical and horizontal directions is necessarily required. Therefore, there is a problem that construction cost and economical efficiency are lowered because the material cost is required and the construction period is lengthened to increase the labor cost burden.

Since the conventional stainless steel lining method uses a welding rod having a different material from that of the lining plate, the bolting method is mainly used in order to prevent corrosion at the welding portion.

However, since the bolt joint method can not tighten all the bolts with the same force because the worker manually tightens the bolt, the panel tightening surface of the portion where the bolt is tightened more loosely than the portion where the bolt is tightened relatively strongly due to the difference in tightness, There may be a problem that water or chemicals leak into the filling space after leakage of the filling material or after reverse application. Therefore, precise attention is required when constructing so that there is no lifting area like this.

It is an object of the present invention to solve the above problems and provide a surface lining structure having excellent workability and economical efficiency by applying a lining structure only by welding, and a method of constructing the same.

As in the previous embodiments, the four-zone edges are welded to the metal bar 310 and the backing plate by titanium welding.

10 is a process flow chart for explaining a method of constructing a surface lining structure according to the present invention.

Referring to FIG. 10, in order to construct the surface lining structure on the inner wall and the bottom of the water tank, the anchor bolts, which are the metal protrusions 112, are installed at regular intervals on the inner wall and bottom of the water tank. Here, the mounting intervals of the anchor bolts 112 are set at proper positions as shown in Fig. 1 in consideration of the width of the titanium metal plate 120. The degree of protrusion of the free end of the anchor bolt is determined in consideration of the installation space of the metal bracket 114 and the metal bar 116.

The metal bracket 114 is disposed so that the free end of the installed anchor bolt 112 is inserted into the insertion hole formed in the vertical portion of the C-shaped metal bracket 114. After adjusting the height and the horizontal of the horizontal portion of the metal bracket 114, the vertical portion of the metal bracket 114 is welded to the anchor bolt 112 (S102).

Then, the channel (116) is fitted in the groove of the metal brackets (114) arranged on the same line so that the vertical part of the channel (116) faces the front. The vertical portion of the channel (116) is provided as a welding surface of the titanium metal plate (120). The distance between the surface of the metal channel bracket 114 and the channel 102 is adjusted according to the degree of overlap between the metal channel 114 and the channel 102. In the state where the distance between the welding surfaces is adjusted as described above, the installation of the metal bar 110 is completed by welding the C channel 116 to the horizontal portion of the metal bracket 114 (S104). The metal bars 110A, 110B, 110C and 110D installed in the step S104 are arranged at the intervals of the upper and lower titanium metal plates 120 as shown in FIG.

Next, the titanium metal plate 120 is disposed between the vertically adjacent metal bars 110A and 110B, the first edge, which is the upper edge of the titanium metal plate 120, is titanium-welded to the metal bar 110B, The edge is titanium welded to the metal bar 110A. The third edge on the left side of the titanium metal plate 120 is titanium-atmosphere atmosphere welded to the backing plate of another titanium metal plate adjacent to the left as shown in FIG. 2 (S106). The back side plate 122 of the titanium metal plate 120 is subjected to taste atmosphere welding on the left side of another titanium metal plate adjacent to the right side. Here, the backing plate 122 of the titanium metal plate 120 may be first welded to the titanium metal plate 120, or may be welded to the fourth edge after welding the upper and lower edges to the metal bar. Also, in the present invention, when the titanium metal plate 120 is used as a 0.5 mm plate, it is also possible to cut the titanium plate in the form of a roll and cut it in the field.

Finally, the filler is filled between the inner wall of the concrete tank or between the bottom and the titanium metal plate (S108). When the filled filler is cured, the titanium lining structure is completed.

Since the titanium metal plates 120 are welded at the four edges by the titanium welding electrode, the gap between the metal plates is spoiled by titanium which is the same material as the metal plate. That is, even if a chemical such as a chlorine component, which is a disinfectant for tap water, is present in the water tank, the welded portion of the metal plate is completely shielded from the titanium material, thereby preventing corrosion due to chemicals. Therefore, there is no fear of corrosion even after a lapse of time, so deterioration of the concrete water tank due to leakage can be completely prevented.

As described above, the field worker can advance the entire work process after the anchor bolt by only the titanium welding tool, so that the work can be performed simply and efficiently.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. It will be understood that the invention may be modified and varied without departing from the scope of the invention.
