The present invention relates to a water storage structure having a non-welded sandwich wall, which uses reinforced concrete as a core material, and has a non-welded sandwich wall wall which can be quickly constructed and semi-permanently sanitarily used by a material covering the inner and outer surfaces of the reinforced concrete. It relates to a structure and a construction method.

In general, repair facilities include water tank facilities for storing water, plumbing facilities, pump facilities, water treatment facilities, and wastewater treatment facilities. In particular, water tank facilities and water treatment facilities should be kept clean so that water is not contaminated. It is essential.

Among most water treatment plants, the impingement wells serve to equally distribute and distribute the flow rate of raw water, which is the natural water that is the source of tap water.

In order to easily remove various turbidity from raw water, the chemical input facility automatically puts chemicals such as PAC (polyaluminum chloride), aluminum sulfate, calcined lime and activated carbon into mixed paper according to the amount of raw water and the quality of water. Admixture is a facility that adds purified water to raw water and mixes it evenly with a stirrer. The flocculation paper coagulates the hazy material (turbidity) uniformly mixed in the mixing paper into a large mass which is easy to settle, and the flocculation paper sinks the flocculation flocs in the flocculation paper to make it clear and clean. The filter paper filters out fine suspended solids that have not been removed from the sedimentation basins with sand and A / C (anthracite), and the advanced water treatment plant passes ozone contact and bioactive carbon filter paper to remove harmful substances from the water. Remove it. In addition, the purified water is temporarily stored after the chlorine disinfection and fluorine injection into the purified water passed through the advanced water treatment facility, the water pump facility serves to push the tap water to each household and drains with a motor pump. In addition, the drainage serves to temporarily supply water for demand, and is installed at a relatively high place to prevent losses such as pressurization and leakage, so that water is supplied to each household at natural pressure.

Such a drainage is a structure having a large capacity to hold water installed in a basement or a building, and has been mostly made of concrete in terms of construction economy, and its shape is usually hexagonal.

However, despite the excellent structural strength, watertightness, and economic efficiency, these concrete drainage basins are moist or corrode on the inner wall over time because they come into contact with moisture. To prevent this, the paint may be contaminated, and even if the inner circumferential surface of the basin is coated to prevent it, the paint may be contaminated by the disinfectant of the tap water itself or by a cleaning disinfectant (eg, CARELAR BIO, CARELAR PLUS) used to clean and disinfect the basin. Hygiene problems have arisen, such as separation from water and water pollution.

The water tank assembly structure according to the prior art is a construction method for coating a thin stainless steel panel on the inner circumferential surface of the concrete water tank conventionally constructed, it is disclosed in Utility Model Registration Nos. 2000-2746 and 2000-16586.

This technique is simply a method of lining stainless panels inside a concrete water tank, which causes a problem that the stainless panel is peeled off from the inner surface of the concrete water tank and uses a plurality of coupling holes in the direction of area expansion. There is still a complicated and difficult problem of connecting the corner portion and the panel joint portion and processing watertightness, and when water leaks in concrete during a long time of use, there is a disadvantage that water leakage and water leakage problems occur.

As a prior art to solve this problem, the present applicant has disclosed a drainage basin having a panel-integrated concrete structure and a construction method thereof through Korean Patent Application No. 2003-19228.

Drainage having a panel-integrated concrete structure of the prior art is a water storage structure having a non-welded sandwich wall consisting of a wall and a floor, a plurality of bent portions and fixing pieces are formed in the middle portion and a plurality of first, A second stainless panel; A plurality of steel panels having grooves formed at four corners and adjacent to each other; At least one horizontal beam coupled to the first and second support plates at both ends of the shaft corresponding to the groove; In order to construct the wall, the horizontal beam is filled with concrete in the side wall panel formwork assembly coupled to the groove of the first stainless panel and the groove of the steel panel, respectively, and the second stainless panel to construct the floor The concrete is covered with the floor concrete before curing, the panel and the concrete is characterized in that it serves as an integral structure.

However, in the drainage system having a panel-integrated concrete structure of the prior art, many welding sites are formed because all panels have to be welded when they are expanded in the width direction, and the construction period is somewhat longer by integrally constructing floor and wall concrete. Complex drawbacks were noted.

In addition, the drainage having a panel-integrated concrete structure of the prior art has a disadvantage in that the curing period is long due to the absence of drainage means when placing concrete, welding each end of the plurality of horizontal beams between the stainless panel and the steel panel Because of the need to join through, there are relatively many welding sites, which requires a large number of welding workers.

In addition, the drainage having a panel-integrated concrete structure of the prior art is a safe structure without reinforcement because the stainless steel and reinforced reinforced concrete is an integrated structure, or the work is inconvenient because it is required to combine the various beams and beams in a structure similar to the formwork structure. Has

In addition, the conventional lip system (1) (LIPP SYSTEM) shown in Figure 1 as a prior art is a tank structure developed in Germany, there is no welding site, even non-skilled people can be installed, fully drained, safe structure without internal reinforcement It is registered as 'KS B 6282'.

However, the conventional lip system 1 has not only a relatively low structural rigidity compared with the drainage paper having the panel-integrated concrete structure mentioned in the prior art by itself, but also the multifold portions 2 are formed in diagonal directions. And maintains no welding, after a long time of use, the reliability of watertight maintenance and maintenance is poor. That is, once the leak occurs in the multi-folding part 2, since water flows down the spiral from the leaked place along the diagonal line, it is difficult to determine where the leak occurs, and the multi-folding part 2 Since the tank itself is continuously connected while maintaining a spiral shape from the bottom to the top of the tank, maintenance of a leaking site is very difficult.

That is, the conventional lip system 1 is a component that can solve the problems of leakage due to the spiral image in the multi-fold portion (2), relatively weak durability problems, securing safety for semi-permanent use and maintenance problems There is no characteristic, it is difficult to apply and use as a drainage basin is a large repair facility.

SUMMARY OF THE INVENTION In view of the problems of the prior art as described above, an object of the present invention is to provide a water storage structure having a non-welded sandwich wall which is quick, hygienic, semi-permanent, and stainless-concrete composite short-time construction is possible.

In addition, another object of the present invention is to provide a construction method of a low water structure having a non-welded sandwich wall that can be bonded to both ends of the connection member fixed to the core material to the inner material and the outer material by a welding-free bonding method.

An object of the present invention as described above is a water storage structure having a non-welded sandwich wall consisting of a wall and a bottom plate and a top plate, the inner shell of the cylindrical shape; A cylindrical outer material disposed outside so as to maintain a predetermined clearance from the inner material; A plurality of connecting members coupled between the inner material and the outer material based on the multiple folded portions of the inner material; And a core material corresponding to reinforced concrete filled between the inner material and the outer material to be fixed to the connection material, wherein the core material, the inner material and the outer material are coalesced by the connecting material.

First, as shown in FIG. 2, the water storage structure having the non-welded sandwich wall of the present invention is manufactured by the manufacturing apparatus 10 of the present invention, which is similar to the lip system but further has a structural feature.

The manufacturing apparatus 10 disclosed in the present invention is a reel member 11 (reel) for mounting any one of a stainless steel coil, a pre-coated material stainless steel coil, and other steel sheet coils, and releasing such coils and discharging them in a strip state. member); A ring member 12 serving as a tank shape maintaining structure supporting member mounting member while maintaining a circular shape; A profile member 13 installed at one circumference of the ring member 12 and serving to form different bent shapes at upper and lower ends of the strips supplied from the reel member 11; A folding member (14) installed on the other circumference of the ring member (12) and serving to form a multi-folded portion by merging end portions of different bent shapes exiting from the profile member (13); Sealing material (eg, installed on the strip inlet portion of the folding member 14 and injecting the sealing material between the end portions of the different bent shapes, passing through the folding member 14 to all inner surfaces of the completed multi-folded portion (eg : Sealing member 15, which serves to uniformly apply any one of the sealing materials selected from watertight silicone, epoxy resin, Teflon resin in the gel state, etc.).

Here, the upper end and the lower end of the strip exiting from the reel member 11 has a straight cross-sectional shape (a, b). In addition, the upper end and the lower end of the strip processed by the profile member 13 are different from the aforementioned bent shape, that is, the upper end of the strip is bent and the end of the 'c' cross-section bending shape ( c), the lower end of the strip has a 'c' cross-section bending shape (d) which is bent at the left end and laid down.

The strips in which these bent shapes (c, d) are integrally formed at the upper and lower ends respectively rotate in a spiral direction.

By the spiral rotation, the upper strip 31 and the lower strip 32 are stacked in a state in which they are spaced apart from each other in the height direction in front of the strip inlet portion of the folding member 14.

The lower end of the upper strip 31 and the upper end of the lower strip 32 are engaged by the operator at the front position of the strip inlet of the folding member 14, as indicated by the letter 'e'.

Here, the bent shape c corresponding to the upper end of the lower strip 32 is engaged with the inner space of the bent shape d corresponding to the lower end of the upper strip 31.

Under this situation, the sealing member 15 uniformly applies the aforementioned sealing material between the bent shapes (c, d).

Then, the bending shape (e) of the strips coated with the sealing material and interlocked with each other passes through the first to fifth folding devices of the folding member 14, respectively, and is referred to as 'f', 'g', and 'h'. , 'i' and 'j' change to a cross-sectional shape.

As a result, in the final step (see reference numeral 'j'), the upper strip 31 and the lower strip 32 have a non-welded joint through the multi-folded portion (30).

The manufacturing apparatus 10 of this invention completes the basic tube 20 of a spiral tube shape or cylindrical shape shown by the dotted line.

When the basic material 20 is integrally integrated with the inner surface (inner circumferential surface) of the concrete in the water storage structure having the non-welded sandwich wall of the present invention, it is referred to as 'inner material 120' (see FIG. 4). After forming a larger diameter than the basic type material 20, when integrally incorporated into the outer surface (inner circumferential surface) of the concrete will be referred to as the 'outer material 220 (see Figure 4)'.

As shown in Figure 3, the multi-folded portion 30 is present in a plurality of while maintaining a certain distance in the height direction of the tank in the inner or outer material mentioned above, but continuous in the wound direction (for example, spiral direction) of the strip Is formed.

The multi-folding part 30 is folded and stacked in a plurality of layers (for example, 5 ply) by bending and stacking the lower end of the upper strip 31 and the upper end of the lower strip 32, while being folded and stacked. The sealing material 50 is interposed in between to perform the watertightness more effectively.

The sealing material 50 preferably has a portion 51 that protrudes slightly at the junction of the first bent portion of the top strip 31 and the bottom strip 32.

The multi-folded portion 30 corresponds to a non-welded coupling portion, and is continuously formed along the spiral direction where the upper strip 31 and the lower strip 32 meet each other.

The multi-folded portion 30 serves as a helical flange in the inner shell or outer shell formed in a spiral cylindrical shape to help increase the structural rigidity.

As shown in FIG. 4, the water storage structure having the non-welded sandwich wall according to the present invention maintains a predetermined distance w (for example, 35 cm), but the inner core material 120 and the outer material material 220 whose shaft centers coincide with each other. Has

The inner shell 120 and the outer shell 220 are completed in a few tens of minutes or two hours in a quick, easy and non-welding manner by the aforementioned manufacturing apparatus.

The installation method of the inner material 120 and the outer material 220 is as follows. After completion of the outer shell 220, the separately completed inner shell 120 can be installed by lifting the crane to the inside of the outer shell 220.

When maintaining the space | interval w of the inner side workpiece 120 and the outer side workpiece 220 to 1 m or more, the inner side workpiece 120 is completed by a manufacturing apparatus. Thereafter, the manufacturing apparatus is re-installed on the outside of the inner cover material 120. In this case, the outer material 220 can be manufactured and completed while maintaining the gap w at the outside of the inner material 120 without lifting the crane.

In addition, in the water storage structure having the non-welded sandwich wall of the present invention, the bottom plate 110 has a shape of any one of circular, conical and corrugated.

At this time, the bottom plate 110 preferably has a diameter corresponding to the diameter of the outer shell 220, the inner shell 120 by the connecting ribs 111, 112 (see Fig. 14), respectively, which will be described in detail below. The lower circumferential edge of the) and the outer circumferential edge of the outer material 220 is coupled by welding.

It is preferable that a porous pipe 300 extending in the vertical or horizontal direction is installed between the inner side member 120 and the outer side member 220 in order to improve drainage during concrete pouring.

The porous pipe 300 is disposed so that one end thereof is exposed to the upper portion of the water storage structure having the non-welded sandwich wall of the present invention, and the other end thereof is connected to the drain hole 310 formed of a plurality of holes in the outer cover 220. In order to discharge moisture generated during curing of the concrete to the outside of the outer shell 220, the inner shell 120 and the inner shell 220 are installed inside the outer shell 220.

The manufacturing method of the drain 310 is briefly described as follows.

First, the circular plate material is cut out by the diameter corresponding to the drain hole from the outer skin 220.

A plurality of through holes are drilled in the circular plate thus cut out, and the pipe connecting edges are protruded outwardly of the circular plate. The circular plate produced in this way is fixed by spot welding only a few places. After connecting the other side of the porous pipe 300 to the pipe connecting edge of the circular plate corresponding to the fixed drain hole 310, the connection point is fixed using a fixing ring, a wire or the like.

On the other hand, between the inner shell 120 and the outer shell 220 over the entire area except the installation space of the porous pipe 300, such as conventional reinforcement reinforcement 321, such as reinforcing bars, mesh (mesh) and concrete such as ready-mixed concrete It is preferable that the 322 is hermetically filled by placing equipment such as a vibrator so that the core material 320 corresponding to reinforced concrete is coalesced.

That is, the core material 320 is cultivated by ordinary reinforced concrete casting using a ready-mixed concrete or the like, and is completely integrated with the surface of the inner material 120 and the surface of the outer material 220 to be completed as a sandwich wall.

The inner material 120 and the outer material 220 have various types of connection materials (first to first for ease of explanation), which will be described below, so that the inner material 120 and the outer material 220 have a function of increasing the function as the formwork and the integrity of the core material 320. It is preferably connected to each other on the basis of the multi-folded portion 30 of the inner shell material (called the fourth connecting member).

A feature of the first to fourth connectors is to connect the inner material 120 and the outer material 220 integrally with each other to minimize the number of welding or no welding at all.

For example, when described in connection with the prior art, in a drain with a conventional panel-integrated concrete structure, both ends of the horizontal beam are joined by welding between the stainless panel and the steel panel, so that at least two to four places Welding was required, and connection points were also provided at both ends, ie two connection points per beam.

However, the first to fourth connection member in the present invention connects the inner material 120 and the outer material 220 without requiring only a maximum of one welding site or no welding at all. By providing a plurality of connection points per one connecting material to minimize the number of welding or no welding at the same time, it is possible to allow the inner material 120 and the outer material 220 to be connected to each other at several connection points. The following describes each of these features.

5 and 6, the first connecting member 410 has two connection points, one of which is coupled to the inner material 120 by an impact fixing method, and the other is a welding or the like. It is coupled to the outer shell 220 by the fixing method.

To this end, the first connecting member 410 forms a 'c' shaped impact fixing part 411 at one end of the bar-shaped shaft 412, and the fixing plate 413 is integrally formed at the other end of the shaft 412. Characterized in that formed.

Here, the bar-shaped shaft 412 extends between the 'c' shaped impact fixing part 411 and the fixed plate 413 in a downward inclined direction, as shown in the figure, or in an upper inclined direction or a horizontal direction although not shown. It is preferable.

The bar shaft 412 prevents the inner shell member 120 and the outer shell member 220 from being spaced apart during curing of the core member 320.

The bar shaft 412 and the 'c' shaped impact fixing part 411 and the fixing plate 413 are fixed inside the core material 320 corresponding to the cured concrete.

When the bar-shaped shaft 412 extends in the inclined direction in the core 320, the 'c' shaped impact fixing part 411 is bent at an end to more effectively play a role as a latch. Of course, even though the bar-shaped shaft 412 extends horizontally, the bar shaft 412 may be coupled to the multi-folded portion 30 of the inner side member 120 without being stably welded by the 'c' shaped impact fixing part 411. Can be.

In addition, the 'c' shaped impact fixing part 411 is a 'b' shaped clamp formed over the inclined upper portion of the multi-folded portion 30 of the inner cover material 120, and extends from this 'a' shaped clamp It has a 'b' shaped cramp formed to hold the site.

The spacing between the ends of the 'a' and the 'b' clamps is widened to correspond to the thickness of the base 31 of the relatively thin portion of the multi-folded portion 30.

When the 'c' shaped impact fixing part 411 is inserted into the multiple folding part 30, which is relatively thicker than the thickness of the base part 31 by the force coupling method, by the action of its own elastic force, As the 'b' is opened and then returned to the original state, the impact fixing is made to surround the multi-folding portion (30).

The fixing plate 413 is fixed to the inner circumferential surface of the outer material 220 by conventional metal fixing means such as welding and bolts.

In such a case, since no welded portion is formed at least in the portion in contact with or near the water, the sandwich wall of the present invention can be utilized.

In addition, the porous pipe 300 is preferably fixed to any one of all the second, third, and fourth connecting materials to be described below, including the first connecting material 410 using the wire 390 or the wire. Do. That is, the porous pipe 300 is supported by the wire 390 or the wire in the second, third, and fourth connector, including the first connector 410 so that it can be stably erected even during reinforced concrete curing.

As shown in FIGS. 7 and 8, the second connecting member 410 has five connection points, four of which are respectively coupled to the inner member 120 by an impact fixing method, and the other is welded. It is coupled to the outer material 220 by a fixing method such as.

To this end, the second connecting member 420 forms a 'c' shaped impact fixing part 421 described above on each of the other four ends of the connecting wire 422 having a spider or 'X' shape having a large number of connecting legs. The welded portion 423 is formed integrally with the overlapping portion of the connection wire 422.

Four 'c' shaped impact fixing portion 421 allows the second connecting member 420 to be coupled to the multiple folded portion 30 of the inner cover material 120 without being welded.

The welding portion 423 of the second connecting member 420 is fixed to the outer material 220 by welding.

In this state, reinforced concrete is cured between the inner shell material 120 and the outer shell material 220, and as a result, the bar-shaped shaft 412 and the 'c' shaped impact fixing part 411 and the fixing plate 413 Is fixed inside the core material 320 corresponding to the cured concrete.

The second connecting member 420 is connected to the inner member 120 through four 'C' shaped impact fixing parts 421 on the basis of one welding part 423 of the outer member 220, and thus the number of welding times is increased. In addition to the reduction, the shape of the spider or 'X' shaped connecting wire 422 allows the outer material 220 and the inner material 120 to be interconnected over a relatively large area. Have

The third and fourth connectors 430 and 440 disclosed in FIGS. 9 to 12 provide the present invention with the ability to form a sandwich wall by complete welding.

9 and 10, the third connecting member 430 has two connection points, one of which is coupled to the inner member 120 by an impact fixing method, and the other of the outer member 220. Is coupled to the outer flank 220 by way of being folded together by folding together at the time of folding of the multiple folds 30 '.

To this end, the third connecting member 430 forms a 'c' shaped impact fixing part 431 at one end of the bar-shaped shaft 432, and relatively thinner at the other end of the shaft 432 and toward the end thereof. It is characterized in that the folding fixing plate 433 which is reduced in thickness is formed integrally.

The 'c' shaped impact fixing part 431 of the third connector 430 has the same configuration as the 'c' shaped impact fixing part described above in the first and second connecting members.

The folding fixing plate 433 of the third connecting member 430 is disposed between the bent shape of the lower end of the upper strip and the bent shape of the upper end of the lower strip in the outer material 220, and then, the folding member 14 of the manufacturing apparatus. As it is bent to correspond to the bent shape while passing through), it is incorporated with the multi-folded portion 30 'of the outer material 220.

The third connecting member 430 is also connected between the inner member 120 and the outer member 220 in a state of being fixed to the core member 320 by a non-welding method.

11 and 12, the fourth connecting member 440 has five connection points, four of which are respectively coupled to the inner member 120 by an impact fixing method, and the other one of the outer member ( When the multiple folding portion 30 ′ of 220 is folded, it is coupled to the outer material 220 in a manner of being incorporated by folding.

To this end, the fourth connecting member 440 forms a 'c' shaped impact fixing part 441 described above on each of the four other ends of the spider or 'X' shaped connecting wire 442, and the connecting wire 442. The 'b' shaped folding fixture 443 is attached to the overlapping portion 444 at the opposite direction to the impact fixing portion 441.

The four 'c' shaped impact fixing part 421 also has the same configuration as that described in the second connection member, and is fixed to the multiple folding portions 30 'of the inner side member 120 by the same impact fixing method.

The upper portion of the 'b' shaped folding fixture 443 of the fourth connector 440 is fixed to the overlapped portion 444 of the connecting wire 442 by welding, and the horizontal of the 'b' shaped folding fixture 443 is fixed. The portion preferably has a shape in which the thickness becomes thinner toward the end and the planar area gradually widens.

The horizontal portion of the 'b' shaped folding fixture 443 is disposed between the bending shape of the lower end of the upper strip and the bending shape of the upper end of the lower strip in the outer cover 220, and then, the folding member of the manufacturing apparatus ( As it is bent in correspondence with the bent shape as it passes through 14), it is incorporated with the multiple folded portions 30 'of the outer material 220.

The fourth connection member 430 can also maintain a stable coupling state at multiple points, while also connecting the inner member 120 and the outer member 220 in a non-welding manner while being fixed to the core member 320. Will be.

As shown in FIG. 13, the inner material or the raw material of the outer material can be used not only stainless material but also a strip of pre-coated material stainless coil.

The strip of pre-coated material stainless steel coil allows the multiple folds 30 "disclosed herein to have a cross-sectional structure in the form of a clad laminate.

In this case, it is not necessary to apply a separate sealing material for watertightness inside the multi-folded portion 30 ″, thereby making it possible to quickly manufacture the inner and outer materials.

As shown in FIG. 14, the water storage structure having the non-welded sandwich wall of the present invention can be applied to repair facilities related to water storage including ground or underground drainage 400 which is a large capacity water storage facility.

For example, when the drainage 400 is installed underground, ① digging work, ② ground level work, ③ floor concrete base work, ④ bottom plate work, ⑤ sandwich wall work, ⑥ piping and concrete pouring work, and ⑦ top plate and It is constructed in the order of construction of finishing work.
