。Conventionally, storage tanks have two structures: steel structures made of thin copper plates and reinforced concrete structures, and each has the following advantages. There are disadvantages. In other words, the former has excellent airtightness and waterproofness, but has problems with buckling, heat insulation, and rust prevention, while the latter has excellent buckling, heat insulation, and rust prevention, but has problems with airtightness. There is a problem that it is inferior in durability and waterproofness. Therefore, a storage tank having a copper plate reinforced concrete structure is known as a storage tank that has solved this problem. This structural type uses steel plates as structural materials by placing steel plates on the inside of the storage tank and reinforced concrete on the outside, and has the advantages of both of the above-mentioned construction types. L7]-5 In this type, there is a problem with the integrity of the steel plate and the concrete IJ'-1-, and the toughness is poor. ) and sub-bins (Y) between these main bins (01 in the figure is steel plate, OG is concrete), the sub-bins (Y) are located between the hopper mounting part and the roof section. There is a problem that the steel plate has to be discontinuous and the airtightness of the sub-bin (Y) cannot be maintained sufficiently.

なるという問題がある。In addition, the following methods are used to construct this type of storage tank. One of them is the special public service in 1970.
There is a method disclosed in Japanese Patent No. 2, in which a first-stage annular inner wall made of glue 11 is manufactured, a shear connector is welded to the outside of the annular inner wall, and reinforcing bars are further arranged through the shear connector. Next, the inside of the annular inner wall is reinforced with shoring, an outer form is provided at a predetermined interval using cylindrical form ties on the outside, and concrete is poured between the inner wall and the outer form.
Form the storage tank wall. Next, a second stage storage tank is formed in the same manner, but in this case, the first
Using the holes formed in the tiered storage tank wall, the shoring and outer formwork are opened several times and concrete is poured in. This process is repeated to construct a storage tank of a predetermined height. 1. As another construction method, reinforced concrete storage JHL17 M4
There is one that uses the Tj1 so-called slip-slip form construction method, which is commonly used for construction. Another method is to make the entire storage tank into parts and erect the precast boards manufactured by Ageo on site.
A method of completing the storage tank 4/EH by welding the joints and filling with mortar has also been developed, and the 'f7' construction method is similar to that of steel 4JJ storage tanks. However, among the above construction methods, the first method is not the slip form construction method, and requires provision of temporary scaffolding on the entire outside.
j! In addition to the types of construction work required under I, work such as erecting and welding steel plates and installing shear belts is required, which makes on-site work complicated and has the problem of poor construction efficiency. When constructing a group of silos with 5 main bins and sub-bins between the main bins, it is necessary to construct all the works at the same height at the same time. In addition to requiring manpower and equipment such as cranes, it also requires multiple skills such as reinforcing bar work, concrete work, and mechanical operator accommodation, and has the disadvantage that the construction work is complicated and difficult to complete. In addition, in the second construction method, since the slip form construction method is used, it is necessary to intersect the yoke when assembling the copper plate, so the copper plate is constructed into small pieces and the pieces are welded. There is a problem that the knee 11 cost becomes very large.

ある。In addition, when constructing a group of silos in the first place, it has the same difficulties as the above-mentioned 10th construction method. Furthermore, in the third construction method, the size of the parts cannot be increased for transportation, so there is a problem that the number of parts is large, and therefore the number of welding steps is also extremely large. In addition, each part must have a structure in which reinforcing bars are joined one by one to the copper plate frame on each side by welding, etc., so the number of welding man-hours and 6i *3'',! There are many problems, such as increasing production costs. Furthermore, there is also the problem that the transportation cost increases significantly depending on the transportation distance.

The fact that it has a wall structure with a force of When building a storage tank by dividing it into several stages in the height direction (lo and gamma), for each stage, an inner wall steel plate with a shear connector on one side and an outer wall copper plate are arranged so that the shear connectors face each other, and the inner wall The work scaffold placed inside the steel plate prevents the inner wall steel plate from deforming inward (one basic feature is that concrete is placed between both steel plates). As a collection method, an inner wall steel plate and an outer wall steel plate each having a shear connector on one side are arranged so that the shear connectors face each other to construct a steel tank, and the steel tank is sealed to reduce the internal pressure. Another basic feature is that concrete is poured between the inner wall steel plates and the outer wall steel plates.

, 1J7 for the secondary bottle shown in Figure 3.
The composite structure storage tank of the present invention, which is obtained by applying the joint plate (6) from below with soil, and then placing the concrete (3), Inner wall copper plate (1) with one side connection (4) and external electrical control panel (2)
Because the concrete is poured between the steel plate and the concrete wall, it is possible to obtain excellent airtightness due to the drawing board, and also to ensure that the steel plate and concrete do not overlap. It has high integrity and can have a structure with excellent toughness. In other words, the concrete penetrates into the steel plate with the shear connector.
Because of its structure, even when the concrete is subjected to heavy loads, the concrete becomes triaxially stressed due to the restraint effect of the steel plates, and toughness that can be achieved without reinforcing bars can be obtained. In addition to these advantages, when constructing a group silo, as shown in Figure 3, the inner and outer wall steel plates (1) and (2) are used for the airtight material and structure of the main bin (X) and sub-bin (Y). It is economical because it can be used as a material, and since concrete acts as an anti-buckling material or a compression material, the thickness of the steel plate can be made extremely thinner than conventional ones.

) and (2) are the formwork allowances, and the lateral pressure due to concrete pouring is due to the outer wall steel *, and (2) is due to the hoop tension of the steel plate itself, and the inner wall hook plate (1) is is supported by the hoop tension and the working scaffold (8) or the tank internal pressure P, so the steel plate protrudes due to lateral pressure 3i without shoring or edge angle f'9:
Can be appropriately prevented. 'Furthermore, both the drawing boards on the outside wall of the vinyl are self-contained, with approximately 9 joints, and only membrane stress acts on them, so there is little deformation, so there is no need for 4 tons of form ties for steel plates. moreover,! If you want to raise a Western-style baby, please prepare a separate JL book 17. for each bottle. It is important to complete the work publicly and independently, and for this reason, compared to the conventional method, it is necessary to complete the work at one time.
It is possible to significantly reduce the number of engineering/jf equipment, etc.

兼用せしめることができる。In addition, as an effect of the tank internal pressure P, a tensile force acts on the steel tank αυ in the axial direction due to the pressure acting on the roof θ'3 and the hopper, so the tank itself is made of thin steel plate. It can fully withstand the load during construction without buckling. Further, although the storage tank is subjected to an airtightness test after completion, in the present invention, this test can also be used to apply the above-mentioned internal pressure P during construction.
