2 is a perspective view of a first embodiment of a prefabricated wall structure according to the present invention, and FIG. 3 is a partial side cross-sectional view of the prefabricated wall structure according to the present invention.

2 and 3, prefabricated wall structure for a water treatment plant according to the present invention is composed of two or more horizontal frames 110 and two or more vertical frames 120 are coupled to the inner wall of the flow channel (2) It comprises a support frame 100 and the panel 200 is formed in a flat plate shape coupled to the support frame 100 to generate a vortex in the fluid passing through the flow channel 2, that is, water to increase the water purification effect do. In this case, the prefabricated wall for the water treatment plant includes both a barrier wall and a ditch wall applied to a water treatment plant and a sewage treatment plant to purify water.

The horizontal frame 110 is arranged to have a length in the horizontal direction and arranged in parallel in the vertical direction, the vertical frame 120 is arranged to have a length in the vertical direction and arranged in parallel in the left and right directions, the horizontal frame ( 110 and the vertical frame 120 are coupled to cross each other. The horizontal frame 110 positioned at the bottom of the horizontal frame 110 is coupled to the bottom of the flow channel 2, and the vertical frame 120 positioned at the outermost side of the vertical frame 120 is the flow channel 2 As coupled to the side wall of the support frame 100 is fixedly coupled to the flow channel (2). At this time, since the flow channel 2 is generally made to have a large strength, such as concrete, the horizontal frame 110 and the vertical frame 120 are coupled to the bottom and sidewalls of the flow channel 2 by the stud bolt 130. Combined.

The support frame 100 is a member for preventing the panel 200 from being pushed backward or damaged by the pressure of the fluid passing through the flow channel 2, and the horizontal frame 110 and the vertical frame 120 are It may be formed in a general rod or rod shape, or may be formed of a pipe having a cross section of a pipe or a shape bent one or more times, that is, a H-beam or an L-beam such as to have a high strength to weight.

At this time, in order to maintain the state in which the support frame 100 is more firmly coupled to the flow channel 2, the vertical frame 120 positioned at the outermost sides at the left and right ends, that is, the left and right sides of the flow channel 2 It is preferable that the horizontal frames 110 are respectively coupled to both inner walls and positioned at the outermost sides of the upper and lower ends, that is, the upper and lower sides, respectively.

The panel 200 is a member that serves to change the path of the fluid passing through the flow channel 2, and is generally made of glass-reinforced thermosetting plastic (GRP) to have high strength to weight and prevent corrosion even after being immersed for a long time. It is made of metal with excellent corrosion resistance such as synthetic resin or stainless steel (STS), zinc alloy and aluminum alloy. In this case, the panel 200 may be formed of a plate having a general flat plate shape, or may be manufactured as a hollow panel 200 having a through hole formed therein so as to increase the strength to weight. In this case, if water is accumulated in the through hole for a long time, the panel 200 may decay. Therefore, the panel 200 may be formed so that water in the through hole may be drawn out of the panel 200. That is, the panel 200 is preferably formed so that the through-hole is formed in the vertical direction so that the water in the through-hole escapes downward and the lower end is spaced apart from the bottom surface of the flow channel (2).

In addition, when the panel 200 is coupled to the rear surface of the support frame 100 based on the flow direction of the fluid passing through the flow channel 2, the pressure of the fluid in the direction away from the support frame 100, the panel 200 ), The panel 200 may be separated from the support frame 100. Therefore, the panel 200 is the front of the support frame 100, ie, the outer surface of the support frame 100, based on the flow direction of the fluid passing through the flow channel (2) of the fluid passing through the flow channel (2) It is preferred to be coupled to the side opposite the flow. When the panel 200 is coupled to the support frame 100 as described above, the panel 200 receives the pressure of the fluid in the direction in which the panel 200 is in close contact with the support frame 100, so long as the support frame 100 is not damaged. The position will not be changed or modified.

Referring to the process of constructing a prefabricated wall structure according to the present invention.

First, the contractor first combines the support frame 100 to the flow channel (2), wherein the process of coupling the support frame 100 to the flow channel (2), first produced the entire support frame 100 After it may be made to couple to the flow channel (2), after combining the horizontal frame 110 and the vertical frame 120 to the bottom, ceiling, both side walls of the flow channel (2), and then another horizontal frame 110 ) And the vertical frame 120 may be arranged to be coupled in parallel.

The support frame 100 is provided with a bolt 310 is coupled to the end portion toward the panel 200 in contact with the panel 200, the panel 200 is in close contact with the support frame 100 The bolt hole 210 is formed in a portion corresponding to the bolt 310 so that the end of the bolt 310 can be penetrated. Therefore, the contractor closely adheres the panel 200 to the support frame 100 so that the end of the bolt 310 penetrates the bolt hole 210, and then the nut (end) of the bolt 310 penetrates the panel 200. By fastening the 320, the panel 200 may be coupled to the support frame 100. At this time, when the panel 200 is made of a material having a relatively low hardness, such as a synthetic resin, there is a possibility that the portion to which the nut 320 is coupled may be damaged by the tightening nut 320, as well as the combined nut ( There is a fear that 320) can be easily released. Therefore, the panel 200 is preferably provided with a reinforcing part 220 for strength reinforcement at a portion where the nut 320 is coupled, wherein the reinforcing part 220 has a higher strength than the panel 200 such as a metal plate. Can be applied as a member of the material. As such, when the reinforcement part 220 is provided in the panel 200, not only the damage of the panel 200, which may occur when the bolt 310 and the nut 320 are coupled, is prevented, and the fastening force of the nut 320 is increased. There is an advantage that the loosening of the nut 320 is prevented.

In the conventional prefabricated wall structure, the panel 200 must be fixed by inserting the panel 200 into a channel-shaped frame, and thus, the construction is complicated, and the frame and panel ( 200) There was a problem that manufacturing is difficult, but the prefabricated wall structure according to the present invention is configured in such a manner that the panel 200 is attached to one side of the frame, as described above, the process of combining the panel 200 is simplified Since there is no need to match the thickness of the panel 200 to the size of the frame, the frame and the panel 200 may be more easily manufactured.

The panel 200 shown in FIG. 2 is configured such that the left and right ends and the bottom of the panel 200 are respectively coupled to the side walls and the bottom surface of the flow channel 2 so that the fluid introduced into the flow channel 2 is transferred upward. The shape of the panel 200 to be applied is not limited thereto and may be freely changed according to a user's selection. That is, the panel 200 is not coupled to the entire support frame 100, but is coupled to only a part of the support frame 100 to cover only the left or right side of the flow channel 2 as shown in FIG. 4. May be

At this time, the support frame 100 and the panel 200 are arranged in the longitudinal direction of the flow channel 2 so that the water passing through the flow channel 2 can generate more vortices, each panel 200 ) Are preferably formed to cover a portion of the flow channel 2 on the side different from the neighboring panel 200.

In addition, as shown in FIG. 5, the panel 200 may be configured to open only one corner of the flow channel 2. In this case, too, each panel 200 may be formed such that a corner opposite to the neighboring panel 200 is opened so that the water passing through the flow channel 2 may generate more vortices. That is, when one panel 200 is configured to open the lower right part, the neighboring panel 200 is preferably configured to open the upper left part.

When the panel 200 is configured to block a part of the water channel 2 with one panel 200 as in the first to third embodiments, the size of the panel 200 is increased as the size of the water channel 2 is increased. In addition, when the size of the panel 200 is increased in this way, there is a difficulty in producing the panel 200 as well as a lot of difficulties in construction.

Therefore, the prefabricated wall structure according to the present invention may be configured to block a part of the flow channel 2 by combining two or more panels 200 to one support frame 100 as shown in FIG. 6. In the embodiment illustrated in FIG. 6, the prefabricated wall structure according to the present invention is configured such that different panels 200 are coupled to left and right sides of one support frame 100, respectively, but one support frame 100 is provided. Different panels 200 may be coupled to upper and lower sides, respectively, or a plurality of panels 200 may be coupled to one support frame 100 in a checkerboard arrangement.

In this case, the support frame 100 applied to the present invention may be used in common even if the size and arrangement of the panel 200 are different. Therefore, in the prefabricated wall structure according to the present invention, the fabrication of the support frame 100 becomes easy, and even if the arrangement of the panel 200 is changed, the support frame 100 can be used as it is, thus increasing resource utilization, and the panel 200. Since the detachment of the panel 200 is simple, there is an advantage in that the arrangement of the panel 200 is easily changed.
