The concrete slab (C) of the above-ground tank is installed so that the pile head of the concrete pile (Steel pipe pile (b) etc.) is buried in the concrete slab (C) of the above-ground tank by approximately 10an. , this joint structure is assumed to be a set-up bottle joint, but in reality it is a semi-rigid structure. As a result, a head pressure bending moment will inevitably occur at t1, ``. As the concrete slab expands and contracts due to temperature changes from the time of placing the pile to the time of receiving the contents, as well as seasonal changes, cracks are likely to occur, and the joint between the pile and the concrete slab may undergo shear failure as shown in d. Arise - become easier.

、杭頭部に発生する曲げモーメントを軽減できる。In the present invention, as described above, in a pile-type above-ground tank, the buffer 1 is interposed at the contact surface between the reinforced concrete slab of the tank and the pile head of the pile supporting the slab. Compared to the conventional structure in which the parts are directly connected, the connection conditions between the two are closer to pin connections, and the bending moment generated at the pile head can be reduced.

におけるクラックの発生を防止するものである。Then, the pile head of the concrete pile (1) is fitted into the recess of the slab (2), and a Teflon plate or the like is installed between the slab (2), the top surface of the pile head, and the outer peripheral surface of the pile head, respectively. By interposing a support plate (7) consisting of a base plate (7) and a filler plate (8) consisting of an asphalt-based filler, the bonding conditions between the concrete pile (1) and the reinforced concrete slab (2) are improved. By bringing the slab closer to the joint, the bending moment generated at the pile head is reduced, and the filling material (8) absorbs expansion and contraction due to temperature changes of the slab, reducing horizontal force generated at the pile head. K, said slab (21
This prevents cracks from forming in the steel.
