Description

[0001] The present invention relates to a fluid storage tank,

The present invention relates to a water tank, and more particularly, to a water tank having a vibration isolator formed by a combination of an elastic pad made of a coil spring or a polyurethane disk having high compression and high elasticity properties and an elastic pad. In addition, it is possible to more effectively prevent the external vibration by receiving the vertical vibration and the horizontal vibration by the multi-connected elastic body, and to prevent the pipe from being disconnected smoothly even when excessive horizontal displacement occurs due to the flexible joint. Or a water tank connected to be discharged.

Generally, most residential and commercial buildings, such as office buildings, apartments, and public buildings, have water tanks installed on the roof or underground for supplying water, and water tanks are installed in factories for supplying industrial water.

Such water tanks are made of various materials. For example, stainless steel, SMC (sheet molding compound), FRP (fiber reinforced plastic), and concrete are used.

Among the technologies related to such water tanks, there are water tanks mainly made of metal such as stainless steel, and these water tanks are mainly used in small size, and in the case of large water tanks, they are mainly made of concrete structures.

The water tank is generally constructed by assembling panels of round or square shape, which are manufactured from SMC (sheet molding compound) or stainless steel, by factory or on-site manufacturing and assembling.

There are various technologies related to such a water tank, including Patent Documents 1 and 2.

Patent Document 1 discloses a steel deck plate wall plates which are erected at predetermined intervals and formed with recesses on both sides thereof, steel deck plate wall plates which are supported so as to be supported by the steel plate supports, synthetic resin wall plates The steel deck plate wall plates are fixed between the steel leg supports and the synthetic resin wall plate sheets in such a manner that the steel deck plate wall plates are fixed successively, And a synthetic resin insulation plate which is fitted and fixed in a recessed groove formed in the shape steel legs.

Such a conventional water tank has a disadvantage in that it takes a long time and a lot of time for construction because of its complicated structure because there is a frame made up of sections and a side wall material.

On the other hand, there is a problem that the water tank is damaged by earthquake due to the vibration or the crustal change due to the construction, or the piping connected to the water tank is damaged and the water can not be supplied. In order to overcome such disadvantages, 2.

Patent Document 2 discloses a water tank which is separated from the ground by a spacing member and spaced above the ground surface. The water tank is provided with a tank main body in which a plurality of unit panels are coupled to each other and a water receiving space is formed therein, And at least one vibration damping means for buffering the vibration transmitted from the tank body to the tank body.

Although watertight tanks having such an earthquake-proof performance are equipped with seismic performance, there are limitations in realizing sufficient seismic performance, and it is impossible to sufficiently accommodate the watertank when vibration exceeding permissible displacement occurs. There is no problem.

However, since the vibration isolator of the conventional water tank is fixed between the bottom of the water tank and the ground, when the horizontal vibration of a predetermined size or more occurs, the vibration isolator suppresses the water tank and prevents the vibration tank from moving. There is a problem that the isolator is damaged or the water tank is broken.

As shown in FIG. 2, a plurality of the vibration isolators 300 may be spaced apart at regular intervals. The vibration isolator 300 is coupled to a lower portion of a bottom frame installed under the water tank.

The bottom frame includes a vertical frame 330 installed in a vertical direction and a horizontal frame 320 installed in a direction perpendicular to the vertical frame 330. The transverse frame 320 and the vertical frame 330 are formed of an H-shaped steel, an I-shaped steel, a d-shaped steel, or the like. The section steel is formed by upper and lower flanges and abdomen, and the vibration isolator 300 is coupled to the bottom frame. In detail, the lower flange and the abdomen of the vertical frame 330 or the horizontal frame 320 are cut at the portion where the vibration isolator 300, which is one kind of the vibration isolator 300, is installed, The upper sliding plate 311 of the buffer member 310 is engaged. Or one of the vertical frame 330 or the horizontal frame 320 may cut the lower flange and the upper flange while leaving only the abdomen so that the remaining abdomen can be folded at right angles to join the folded abdomen with the abdomen of the other flange. As described above, the combination of the horizontal frame 320 and the vertical frame 330 can be changed into various forms. In addition, the horizontal frame 320 and the vertical frame 330 are coupled to the upper portion of the foundation concrete 200 in a lattice form. When the interval of the foundation concrete 200 is long or the load of the upper fluid is increased, And can be further combined between the respective gratings.

As shown in FIG. 2, the bottom frame supporting the lower surface of the water tank includes a horizontal frame 320 and a vertical frame 330, and a vibration isolator 300 is coupled to the lower portion thereof. The vibration isolator 300 may be divided into a cushioning body 310 and an elastic pad 340 and may be installed at a portion where the horizontal frame 320 and the vertical frame 330 are coupled to each other.

Specific shapes of the buffer 310 and the elastic pad 340 are shown in FIGS.

3 shows an example of the buffer 310. FIG. 3, an upper slip plate 311 provided on the bottom surface of the bottom frame formed by the transverse frame 320 and the vertical frame 330 coupled to the water tank and having a slide plate 312 formed on the bottom surface, ; A lubricant sliding plate (313) for receiving horizontal vibration applied to the water tank in contact with the slide plate (312); And grooves of a predetermined size and depth are formed on the upper surface for fixing and inserting the lubricant sliding plate 313 and the lower surface is provided with grooves for receiving the elastic body 316 for absorbing the vibration acting vertically, An intermediate fixing plate 314 having an annular projection (not shown) for receiving the elastic body 316; An elastic body 316 which is fitted between the intermediate fixing plate 314 and the lower fixing plate 315 and absorbs vibration transmitted vertically; And a lower fixing plate 315 for receiving the lower surface of the elastic body 316 and transmitting the vertical vibration energy transmitted through the elastic body 316 to the base concrete 200.

Further, a groove for fixing the lubricant sliding plate 313 is formed on the upper surface of the intermediate fixing plate 314, and a lubricant sliding plate 313 is inserted into the groove. The lubricant sliding plate 313 is formed to abut the sliding plate 312 coupled to the lower surface of the upper sliding plate 311 so that the lubricating sliding plate 313 can smoothly move when horizontal vibration occurs. The lubricating sliding plate 313 may be coated with solid oil on the lubricating sliding plate 313 so as not to generate a frictional force when sliding with the sliding plate 312. The solid lubricant may be applied to prevent friction, and a lubricant sliding plate may be made of a plate such as PTFE. Further, friction type PTFE capable of friction with the lubricating sliding plate 313 can be used so that the horizontal vibration energy can be diverted into frictional heat. In this case, the friction type PTFE can dissipate the horizontal vibration energy by radiating heat due to the movement friction with the slide plate 312. These examples are the same as those of a seismic isolation device that is installed on a building or a bridge and disperses the earthquake load.

The elastic body 316 must be able to sufficiently accommodate the vertical vibration and be able to withstand and be able to withstand horizontal vibrations by more than a predetermined value. For this purpose, the elastic body is applicable as a coil spring. The coil spring compresses and restores in the coil direction, so that the vertical vibration can be absorbed and dispersed.

A circular protrusion (not shown) protruding to a predetermined size is formed on the lower portion of the intermediate fixing plate 314 and the upper portion of the lower fixing plate 315 to securely receive and receive the elastic body 317. The circular protrusion serves to prevent the elastic body 317 from coming off. Further, a groove for fixing the lubricant sliding plate 313 is formed on the upper surface of the intermediate fixing plate 314, and a lubricant sliding plate 313 is inserted into the groove. The lubricant sliding plate 313 is formed to abut the sliding plate 312 coupled to the lower surface of the upper sliding plate 311 so that the lubricating sliding plate 313 can smoothly move when horizontal vibration occurs. The lubricating sliding plate 313 may be coated with solid oil on the lubricating sliding plate 313 so as not to generate a frictional force when sliding with the sliding plate 312. The solid lubricant may be applied to prevent friction, and a lubricant sliding plate may be made of a plate such as PTFE. Further, friction type PTFE capable of friction with the lubricating sliding plate 313 can be used so that the horizontal vibration energy can be diverted into frictional heat. In this case, the friction type PTFE can dissipate the horizontal vibration energy by radiating heat due to the movement friction with the slide plate 312. These examples are the same as those of a seismic isolation device that is installed on a building or a bridge and disperses the earthquake load.

The elastic body 317 must be able to sufficiently receive the vertical vibration and be able to withstand and move beyond a predetermined value even in the horizontal vibration. For this purpose, the elastic body 317 may be applied in the form of a polyether disc having a high compression and high elasticity property. The polyurethane disk is in the shape of a circular plate, and a hole of a certain size is formed at the center. In addition, grooves are formed on the outer edge of the polyurethane disk in the form of V, U, and semicircular shapes. When the polyurethane disk is compressed, the polyurethane disk is horizontally expanded into grooves formed on the outer edge and restored to its original shape after compression. The nature of the material of the polyurethane disk is as follows.

A shear key in the form of a circular column may be additionally coupled to the hole formed in the central portion of the polyurethane disk to resist horizontal vibration and prevent the polyurethane disk from flowing out to the outside. The shear key penetrates a hole formed in a central portion of the polyurethane disk and is coupled to the lower surface of the intermediate fixing plate 314. In the intermediate fixing plate 314, a thread groove is formed for fixing the shear key formed of the steel material, and a thread is formed at one end of the shear key that is coupled to the intermediate fixing plate 314 so that the thread of the shear key is screwed and fixed to the thread groove. The lower fixing plate 315 is formed with a through hole at the center of the lower fixing plate 315 so as to partially receive the other end of the shear key and resist the horizontal force. When the polyurethane disk is vertically deflected by the upper load through the through hole, the shear key is simultaneously deflected and moved through the through hole of the lower fixing plate 315, thereby accommodating the polyurethane disk. In addition, when the horizontal vibration is excessively generated, the shear key is once fixed to a hole or a through hole formed at the center of the intermediate fixing plate 315 and the lower fixing plate 315, and the other end is fixed at a free end, You can resist. The through holes formed at the center of the lower fixing plate 315 are formed to be equal to or equal to the diameter of the shear key. However, the size of the through hole can be made larger so that the permissible rotational angle of the polyurethane disk can be less than 0.03 rad as compared with the case where the polyurethane disk is eccentric to one side.

Although not shown in the upper slip plate 311 and the lower fixed plate 315, a separate hole may be formed on the outer surface of the upper slip plate 311 so as to be fixed to the bottom frame and bolted together. When the bolts are not fastened, the outer surface of the upper slip plate 311 can be welded to the bottom frame. A separate flange may be formed on the outer surface of the lower fixing plate 315 or may be formed larger than an area capable of accommodating the elastic body 317 and a hole may be formed in the flange to be coupled with the upper portion of the base concrete by bolts .

5 shows an example in which an elastic pad 340 is installed between the bottom frame and the foundation concrete. 1, 2, and 5, the elastic pad (not shown) is attached to a central portion or a side surface portion of the bottom frame where the horizontal frame 320 and the vertical frame 330, which are formed of the H-, I- 340 are coupled and supported.

[ In order to engage the lubricant sliding plate 342 with the elastic body 343, the lubricant sliding plate 342 can be bonded by adhesive bonding, heat sealing bonding or inserting. A slide plate 341 is coupled to the lower surface of the bottom frame made up of the horizontal frame 320 and the vertical frame 330 so as to be slidable in contact with the lubricant sliding plate 342 in the longitudinal direction. The lubricating sliding plate 342 may be coated with solid oil on the lubricating sliding plate 342 so as not to generate frictional force when sliding with the sliding plate 341. The solid lubricant may be applied to prevent friction, and a lubricant sliding plate may be made of a plate such as PTFE. Friction type PTFE capable of friction with the lubricating sliding plate 342 can be used so that the horizontal vibration energy can be diverted into frictional heat. In this case, the frictional PTFE can dissipate the horizontal vibration energy by radiating heat due to the movement friction with the slide plate 341. These examples are the same as those of a seismic isolation device that is installed on a building or a bridge and disperses the earthquake load.

The elastic body 343 is formed of a flexible material such as rubber or polyurethane, and is capable of moving in a horizontal direction. Particularly, when used as a friction material such as friction type PTFE by the lubricant sliding plate 342, the elastic body 343 moves horizontally in a small horizontal load such as wind or the like and receives a horizontal load The lubricating sliding plate 342 made of friction PTFE acts between the slide plates 341 to dissipate excessive horizontal vibration energy.

The elastic pad 340 may be integrally joined with one or more elastic members 343, and a shim plate made of a steel material may be inserted therebetween. A through hole is formed at the center of the stacked elastic body 343, and an anchor bolt is coupled to the through hole to be coupled to the base concrete. In this case, the elastic body functions merely as an elastic supporting function, but does not support a horizontal load.
