The present invention mainly relates to wall linings that cover steel plates on the outer surfaces of concrete structures and the like. More particularly, the present invention relates to a structure for connecting a steel sheet panel and a steel sheet panel for steel sheet overlay, that is, lining.

Conventional method of connecting steel plate and steel plate has a method of welding or connecting bolts or rivets, but there is a limit to welding or connecting thin steel plates with bolts or rivets, and welding work in a place where the working space is almost enclosed. In the case of glass roofing, the method of attaching glass to the rigid body forming a glass roof has a disadvantage in that water is leaked when the glass is expanded or stretched due to strong sunlight and temperature change.

In order to solve the above problems, the present invention connects the steel plate and the steel plate without the bolt and rivet bonding or welding when lining the panel, such as steel sheet, the degree of water leaking, the connection parts and the steel sheet Structure can be expanded or stretched by inserting it without being integrated by welding, and by allowing the expansion amount to be absorbed by leaving a free space so that the panel does not come into close contact with the connection part due to the expansion. And it is an object of the present invention to provide a wall lining that can prevent the destruction of the panel (panel), such as a steel sheet (lining) and a connection part suitable for the lining and a wall reinforcement method using the wall lining.

The present invention for achieving the above object is to connect and fix the steel plate and the steel plate when lining (panel) such as steel plate (panel) on the wall surface or mortar wall surface of the concrete structure such as concrete tank In addition to the method of welding, there is provided a wall lining that can be made by a steel sheet lining method without welding the connection portion.

)연결부속을 구조물에 앵커볼트 등으로 고정시키고 연결부속 ㄷ자 가운데에 강판등 패널(panel)을 끼워 넣어 연결하는 것을 특징으로 한다.Such wall lining is a bi-directional c-shaped (2) type which is a very suitable connection method in the case where the steel plate is thin and requires very skilled welding technology or when bolts or rivets are inadequate.

A) Anchor bolts are fixed to the structure with anchor bolts, and the panel is inserted into a panel with a steel plate.

In addition, the present invention is characterized in that when the order is required so that water does not leak from the connecting portion to insert the index packing between the groove and the panel of the connecting portion to order.

In addition, the steel plate and the water seal can be closely adhered to the water pressure part, so that the water pressure plate can be inserted between the connection part and the water seal so that the water does not leak, and the press bolts can be tightened to be completely filled.

According to the wall reinforcement method using the wall lining of the present invention, when concrete needs to be repaired due to aging due to neutralization, etc. Connection parts can be made to secure the space as much as the required mortar or reinforced concrete thickness, and the steel plate can be used as formwork.

At this time, in order to prevent the steel sheet from sagging or falling off due to the mortar or the weight of the reinforced concrete, a band-shaped reinforcing plate may be placed on the front surface of the steel sheet at regular intervals determined by structural calculation, and reinforcement cement mortar or concrete may be poured. It is desirable to.

The connection part for wall lining of the present invention may have a short type and a long type as a basic linear connecting part, and a connecting part having a c-shaped groove in both directions and a fixing means for fixing the connecting part to a target wall surface, for example, A bolt hole may be formed in a portion extending from the connecting portion, and a fixing means such as installing a bolt or installing a rivet or a nail may be provided. When the linear connecting parts are arranged in a checkerboard shape in the longitudinal and transverse directions on the wall surface, the grid point may be provided with cross-shaped (+ type) connecting parts connecting the linear connecting part, the groove part and the rigid part.

On the other hand, for the wall reinforcement method of the present invention may be further provided with an extension portion connected to the connection portion to be perpendicular to the groove direction of the connection portion so that the steel plate is spaced apart from the wall surface in the connection portion.

After fixing to the concrete surface with anchor bolts (23), insert the steel plate (eg 21a), and then insert the other side (eg the right or upper part) into the steel plate, and then fix it to the concrete (10) side. : 21b) can be inserted and the lining work is completed by repeatedly inserting and fixing the connecting parts. At this time, after fixing the connecting parts in advance, a little more margin is provided between the connecting parts and the connecting parts so that a panel such as a lining steel sheet can be inserted, and the connecting parts are fixed to the concrete surface 10 first. After installation, it may be possible to insert a panel such as a steel sheet.

On the other hand, in a structure in which water should not leak between panels such as overlaid steel sheets, an index packing 24 is inserted between the panel and connecting parts such as steel sheets, or an index agent is injected to make the order. 22a) was inserted into the short (22b) and long (22c) connecting parts and fixed installation, and in order to prevent the leakage of water into the gap inserted by injecting epoxy or silicone, water, etc. into the connection (j) This can be prevented from leaking and water can be prevented with minimal welding only when absolutely necessary.

When the front surface (S3) and the concrete surface (S1) of the) is separated and the steel sheet touches the concrete surface (S1) by hydraulic pressure, the steel sheet is bent, so that the water-proof packing (24) in the connecting part does not come into close contact with the steel sheet end and thus cannot be ordered. In order to prevent this from happening, the steel sheet 60 is provided with a bent portion g to produce and install the steel sheet. The space between the steel sheet 60 and the structure surface S1 is filled with a filling material 61 so that the steel sheet is not bent by water pressure. It is to avoid. If the steel plate surface (S3) and the connection part surface (S2) to match the aesthetic appearance may be better.

After tightening the bolts 91 to prevent the release of the reinforcing plate is in close contact with the connecting portion to receive a steel sheet to show one form of the integral reinforcing plate to prevent the steel sheet from leaving. Anchor bolt is installed to increase adhesion by equally applying force to the joint while preventing the bolt from coming into contact with the joint when it is tightened.

FIG. 10 is an enlarged view of a plan view (or front view) of a combination of the three connecting parts of the cross section 22a, the short form 22b, and the long form 22c of FIG. 22a2 and 22a3 are welded along a weld line w. FIGS. 10a to 10e are developed to produce the three cross, short, and long connection parts described above. The center part 22a1 of a cross connection part was developed, and FIG. 10B is the figure which developed the right part 22a2 of the center of a cross connection part, and FIG. 10C is the figure which developed the left part 22a3 of the center of a cross part connection part. . And by folding the steel sheet along the fold line (f) of the developed drawings, and welded along the weld line (w), it is possible to produce a central cross-shaped connecting part (22a), Figure 10d is a short connecting part (22b) 10e is a drawing showing the elongated connection part 22c, which is manufactured by folding a steel plate along a fold line f, and fitting it to the fitting line p of the central connection part 22a, and then anchor bolt. It is very easy to manufacture or install because it is fixed to the furnace structure and water can be injected into the fitting part.

Since welding is not performed, the coating to prevent corrosion of the steel sheet is not likely to be damaged by the heat generated during welding, so it is possible to lining all coated and coated steel sheets, etc. It is possible to work in a confined space that is hardly ventilated, such as inside the water tank, and the construction cost is low due to the reduction of welding products and the increase of working efficiency.

It is a connecting method that separates panels such as steel sheets by inserting the connecting parts into the connecting parts without integrating panels such as steel plates by welding, etc., so that the amount of expansion or expansion of the steel sheets due to temperature change can be absorbed into the free space in the connecting parts. Therefore, it is not necessary to install a separate expansion joint or the like to cope with the expansion and contraction of panels such as steel sheets, and it is also applicable to glass plate construction having a large expansion and expansion.

There is an exponent packing between the connection part and the steel plate so that it can be used for water structures or glass roofs where water should not leak.

The parts and equipment necessary for the work are simple, so the construction is easy even in narrow places.

Meanwhile. Since it serves as an electrical insulation by the exponential packing of the connection portion, there is a feature that can prevent the electrical corrosion by the potential difference between dissimilar metals,                     

By using steel plate as a formwork substitute, it is also possible to apply reinforcement reinforced concrete or mortar to existing structures, making construction easier and significantly reducing construction costs.
