In particular, the rectangular multiple partition wall 140a is a flange bending portion of the 'b' cross section, a flange bending portion of the 'c' cross section shape, a flange bending portion of the 'ㅁ' cross section shape, a circular flange, as in the prior art A barrier panel (not shown) having a curled portion is extended in the longitudinal direction to form a rectangular first stage unit, and the second, third and fourth stage units are connected to the first stage unit in the same extension manner. It is constructed while repeating lamination and welding on top of each other.

In addition, as shown in Figure 8b, if a person having ordinary knowledge to understand the description of the present invention, the storage tank having a wall structure consisting of a concrete and a vertical panel of the present invention integrally with the side wall 100 described in detail above It will be readily appreciated that it will comprise multiple partition walls 140b constructed in the same manner.

In this case, the rectangular multiple partition wall 140b is constructed inside the sidewall 100 only by further performing the bottom and sidewall reinforcement work and the vertical panel and the outside formwork as in the construction order of the sidewall 100.

In particular, the through passage 141 such as a straight flow path tube, an inclined flow path tube, a perforated plate, a flow path, and the like in the lower portion or the upper portion of the rectangular multiple partition wall 140b is a vertical panel and two vertical panels facing each other during an external formwork. And after arranging the stainless pipe in advance between the outer formwork, the both ends of the pipe may be made by welding the coupling holes drilled in the vertical panel and the outer formwork.

Hereinafter, a construction method of a storage tank having a concrete and vertical panel integrated wall structure according to the present invention will be described with reference to FIGS. 3 and 9.

When the side wall 100 is constructed on the ground or inside the building, the construction sequence of the side wall 100 is as follows.

First, the ground leveling is performed on the ground or inside the building, and the floor and sidewall reinforcement work is performed, and then the vertical panel 110 and the outer formwork 410 are performed.

Subsequently, the concrete base part pouring, curing work (S2) and the bottom plate work and the concrete part placing work (S3) in parallel to the side by finishing the finishing work (S4), such as passive film regeneration treatment, it becomes a concrete vertical panel integrated structure.

More specifically, the ground leveling construction is to properly mix the soil and gravel to level the floor surface or to maintain the 'V' cross-sectional shape in the longitudinal direction in consideration of the water flow direction as shown in Figure 3 the ground 20 To form.

In addition, in the reinforcement construction of the concrete base 300 and the side wall 100, the formwork for the concrete base is performed in parallel, and at the same time, the rebar 320 and the rebar mesh 321 may be woven to the ground 20. Along with this, the worker may use other reinforcing bars 322, that is, the reinforcing bars embedded in the concrete unit 120 as longitudinal reinforcing bars, and other reinforcing bars 323. After erecting perpendicular to the ground (20) in connection with 321, and extending along the outer side of the side wall 100, thereby forming a basic outer reinforcement frame 324. At this time, the reinforcing bar 320 and the reinforcing bar 321 on the ground 20 side may be changed in the shape of the rebar structure to correspond to the planar or V-shaped surface shape. And, the concrete base formwork 330 is a steel prefabricated formwork using a product that can be easily found in the conventional construction industry. These products have a number of bolt holes in the side of the formwork that allow bolting.

Formwork 330 for the concrete base in the present invention also serves as a support structure for fixing the vertical panel 110 perpendicular to the ground (20).

Thereafter, the vertical panel 110 is attached to the upper end of the reinforcement 320 embedded in the concrete base 300 by welding or the like, and the flanges 111 are welded between the vertical panels 110, respectively, and in addition, by fixing means. By fastening, the inner circumference of the side wall 100 is completed, and at the same time, the outer formwork 410 is installed to be separated by the thickness of the concrete part 120 as shown in FIG. 9.

In addition, in the vertical panel 110 and the outer formwork 410 construction, a plurality of horizontal support rods 430 corresponding to the width (height) and the spacing of the vertical panel 110 and the outer formwork 410 are shown in FIG. 9. It is fixed so that the concrete portion 120 between the vertical panel 110 and the outer formwork 410 can support their load during casting and curing. Thus, in the construction method of the present invention, since the vertical panel 110 can be used as a formwork, the construction is easy and the material cost is reduced.

On the other hand, in the present invention, when it is difficult to bear the load of the concrete part only by the vertical panel 110, that is, when the thickness of the wall is large, as shown in Figure 9 in the step of constructing the vertical panel 110 and the outer formwork 410 The inner formwork 420 may be installed on the inner surface of the vertical panel 110, that is, the surface in contact with the water. The inner formwork 420 is installed on the inner side of the vertical panel 110 by using a double-sided tape 421 to facilitate the installation of the inner formwork 420 and to form the inner formwork 420 from the vertical panel 110 during finishing. There is an advantage of easy separation.

Subsequently, the concrete base portion 300 pouring and curing work is evenly cast concrete (product name KS ready-mixed concrete) mixed with water, aggregate, and cement inside the formwork 330 for the concrete base portion, and the steel reinforcement 320 laid on the ground 20. The step of forming the bottom concrete part to completely cover the reinforced mash 321.

The concrete part 120 of the side wall 100 is to be poured at the same time as the concrete base part 300, and the concrete base is evenly placed between the vertical panel 110 and the outer formwork 410. The concrete portion 120 of the side wall 100 is formed while being coalesced with the concrete at the time of pouring.

In addition, in the construction of the bottom plate 130 on the top of the concrete base 300, at least one bottom plate panel (not shown in the drawings) before the poured concrete base 300 has a predetermined strength (5 kg / cm 2 to 10 kg / cm 2). After covering the upper part of the concrete base 300 with a close contact, and is connected to each other by welding the joint around the bottom panel panels.

When the construction of the side wall 100 is completed, the top plate 200 is installed and finished. The finishing work is performed by dismantling the formwork and performing passive film regeneration. The passive film regeneration is performed by the bottom plate panel and the vertical panel (110). This is a treatment step to prevent corrosion by forming a film on the welded part of).

On the other hand, in the present invention, in order to construct the concrete base 300, the concrete base formwork 330 was used, but when installed in a place where the concrete base 300 is not necessary, the installation of a separate concrete base formwork 330 Naturally, no work or dismantling is required.
