Abstract

PURPOSE:To assure safety of membrane by providing free length to iron rod at the joint while providing a gap between side wall an bottom plate to absorb horizontal displacement at the joint. CONSTITUTION:Iron rods 4 at the joint are separated from concrete through PC rods in radial and circumferential direction while free length (L) is provided to allow free expansion/contraction of rods 4. Consequently a gap 8 is provided between side wall 5 and bottom plate 3 and even for large horizontal displacement of side wall, iron rods at the joint will expand/shrink to absorb it.

。The applicant previously proposed LNG as shown in Figures 1 and 2.
We proposed an underground storage tank (Patent No. 966577). In other words, this storage tank has a double slab structure by cutting the upper floor plate 1 with the bottom plate 3 using a cutting material 2 such as asphalt,
The upper floor plate 1 is connected to the side wall 5 with reinforcing bars 4, and blind areas 6 are provided in the upper floor plate 1 in the circumferential direction and radial direction, so that the horizontal displacement of the side wall 5 is absorbed and dispersed by the joints 6.

In the case of structural construction, in order to ensure the safety of the membrane, the upper floor plate joints must have a flexible structure so that this large horizontal displacement can be absorbed and dispersed as evenly as possible.

In the storage tank of the present invention, as shown in FIGS. 3 and 4, the upper floor plate 1 is separated from the bottom plate 3 by an edge cutter 2 made of, for example, a Teflon sheet, and the upper floor plate 1 is connected to the side wall 5 by reinforcing bars 4. The upper floor slab 1 is provided with blind areas 6 in the circumferential direction and the radial direction. As shown in detail in Fig. 5, the reinforcing bars 4 at the joints are edged with the concrete in both the radial and circumferential directions using winding sheaths 7 for PC steel bars. A free length t is provided so that it can expand and contract freely.

Even if the horizontal displacement of the side wall becomes large because the design is such that there is a gap 8 between the bottom plate 3 and the bottom plate 3, the reinforcing bars at the joint can expand and contract freely to absorb the large horizontal displacement at the joint. I can do it.
