Description

Pedestal Integrated Seismic Water Tank {Water STorage Tank having a Reinforced Frame and Pad for Earthquake-proof}

The present invention relates to a pedestal-integrated seismic water tank having an external sub-steel frame structure, in which a floor frame, a vertical frame, and a ceiling frame are integrally combined so as to have structural stability against water pressure and seismic load (horizontal seismic force) acting on the water tank. It relates to a seismic water tank having a closed rectangular frame structure.

In general, a water tank is a tank used as a means for storing water for living, including drinking water and washing water, and in order to facilitate construction, a prefabricated water tank is widely used.

The prefabricated water tank is typically constructed by assembling rectangular unit panels made of SMC (sheet molding compound) or stainless steel at the construction site. When water is stored, the structure is deformed by water pressure, and when it is manufactured in a large size, durability is lowered.

As a technology related to such a prefabricated water tank, there are various things including Patent Documents 1 to 3.

Patent Document 1 is composed of a bottom disposed at the bottom and a wall part with a lower part fixed to the bottom part and extending to the upper part, and a cover part covering the upper part of the wall part, and the wall part is a cross-sectional shape of an H-shaped steel with fitting grooves on the left and right sides In the case of being composed of vertical posts and synthetic resin wall boards (PDF panels) supported by vertical posts and vertical posts that are fixedly supported by being inserted into the fitting grooves of vertical posts, the cross bars and vertical posts are The step caused by the difference in thickness is removed by adding and removing separate flat members having a thickness equal to the thickness difference on the outer surface of the crossbar except for the part fitted into the fitting groove, so that the wallboards made of synthetic resin are applied to the vertical posts and crossbars. It is configured to be tightly supported without stepping,

Patent Document 2 discloses a plurality of bottom panels connected to each other to form a floor, a plurality of side panels connected to and installed on a plane perpendicular to the bottom panel and connected to an outer edge of the floor with a lower end to form a side wall; , a plurality of ceiling panels perpendicular to the side panel and installed connected to each other on a plane facing the bottom panel, and the outer edge is connected to the upper end of the side wall to form a ceiling, wherein the ceiling panel comprises a corner It consists of a flat part formed as a flat part and a flange part formed by bending vertically upward from the edge end of the flat part,

Patent Document 3 discloses that in a prefabricated water tank provided with an external reinforcing member to reinforce durability, a plurality of unit panels having at least one fastening hole near a corner are coupled to each other to form a water storage space therein; A nut member press-fitted into each fastening hole, and a connecting hole corresponding to the fastening hole formed in the plurality of unit panels coupled to each other are formed on one surface. It includes a bolt member.

As described above, the conventional prefabricated water tank has a reinforcing structure using a reinforcing member or vertical post to protect the water tank from the pressure of water stored therein. There is a problem in that the panel supported by the reinforcing posts is separated from the reinforcing posts, thereby damaging the water tank or causing water leakage.

Patent Document 4 discloses that in an assembled plant tank including a tension adjusting means for adjusting the tension of a reinforcing wire, the reinforcing wire is a wing fixing groove formed in a panel fixing bracket to correspond to a portion welded to an end of a coupling wing formed on an edge of a steel plate panel. The panel fixing bracket not only reinforces strength by bending the outside of the wing fixing groove outward one or more times so that the end of the reinforcing bent part is in close contact with the inner wall of the external reinforcing post, By expanding the contact area of the reinforcing posts, the panel fixing brackets are more firmly supported by the external reinforcing posts. Corner panel fixing brackets installed at the corners of the water tank are installed, and the corner panel fixing brackets fix two wings. It has a groove and is shaped so that the two wing fixing grooves are at right angles to each other, and the waterproof sheet is installed only on the connection part of the steel plate panels on the inner wall of the water tank to prevent leakage between the steel plate panels. .

However, such a conventional water tank has problems in that it is difficult to manufacture and install, as well as leaks may occur due to gaps between the steel plate panels due to external vibration or seismic vibration.

In particular, when an earthquake occurs, the water tank wall is subjected to compressive and tensile forces due to ductile vibration, so that the prefabricated water tank having an internal reinforcement structure by a round bar or wire may be easily damaged.

However, even in the prior art, as shown in FIG. 2 , a pair of left/right vertical members 2L and 2R having a symmetrical cross section are coupled to face each other to form a side vertical frame, Many structures are known for supporting the water tank wall panels by integrally coupling the vertical flanges 1V to the left and right.

However, since the side vertical frames disclosed in the prior art were in the form of beams manufactured to have the same length as the height of the water tank, there has been difficulty in transporting them and bringing them into the work site. In addition, as shown in the circle shown in FIG. 1, the conventional left and right vertical members 2L and 2R are cut-out grooves G-L for accommodating the horizontal flanges of the unit panels constituting the wall of the water tank ( G-R) are formed, respectively. Since the pair of left and right vertical members 2L and 2R receives a bending stress in the outward direction of the water tank, two cut-out grooves G-L (G-R) of the left and right vertical members 2L and 2R It is formed at the same height, and stresses are concentrated in these cut-out grooves, and consequently, problems are pointed out in which the rigidity of the vertical frame becomes very weak.

In order to compensate for this, there are many cases where additional reinforcement is added to the area where the incision grooves G-L (G-R) are formed. In order to separately manufacture the additional reinforcement, many ancillary operations are required, and a lot of time and labor cost increase factors for installation work. acts as
