So-called prefabricated storage tanks installed on the rooftops or basements of buildings are required to be extremely earthquake resistant. However, the bottom wall can be fixed to a frame fixed to the base, but for side walls that stand upright from this, there is no means to firmly fix the bottom wall, so a tension rod is stretched between the opposing side walls. In addition, diagonal braces were inserted between the side walls and the bottom wall to improve earthquake resistance.

ある。 Recently, external reinforcement methods have been developed to replace these so-called internal reinforcement methods, and the earthquake resistance of side walls has also been significantly improved. For ceiling walls that are attached to the top of side walls using bolts and nuts, there has been no effective means to improve seismic resistance, and in seismic tests, there is a possibility that damage may occur at the attachment point between the ceiling wall and side wall. .

６の破壊に至る可能性のあることが判明した。 Figure 1 shows a panel 2 constituting a side wall 1 with a height of 2
m, width 1 m, the side wall 1 is constructed by connecting surrounding flanges 3, and the flanges 3 are reinforced with an outer reinforcing material 4 forming a loop, and the bottom wall (not shown)
The ceiling wall 5 is constructed by similarly connecting 1 m x 1 m panels 6 with flanges 7. However, according to seismic tests (conditions: sine wave resonance input several times higher than gravitational acceleration), cracks may occur at the attachment point between the side wall 1 and the ceiling wall 5, and this may lead to the destruction of the panel 6 constituting the ceiling wall 5. It turns out that there is.

に集中することによるものである。 Figure 2 shows the installation of the side wall 1 and ceiling wall 5.
The first crack mentioned above occurred near the bolt 8 that fixed both walls, and the head of the bolt 8 was attached to the ceiling panel 6.
This is caused by the screw coming off the flange 7 or the head of the bolt 8 breaking off. This means that during vibration, the force is applied to this bolt 8 in the relationship between the side wall 1 and the ceiling wall 5.
This is by concentrating on

The present invention includes a peripheral flange 7' of a ceiling wall 5, which is constructed by connecting flanges 7'' projecting downward around a plurality of horizontally installed panels to each other with a plurality of flange connection bolts 16; This storage tank ceiling reinforcing structure is used when connecting the upper end of a vertical wall, and a reinforcing tool 12 is stretched between the adjacent parts of the vertical wall and the ceiling wall, and this reinforcing tool 12 is made of a plate material and is provided at one end. A tongue piece 13 is overlapped with the flange 7'' of the ceiling wall, and this tongue piece 1
3 is fixed to this flange 7'' by a flange connecting bolt 16 closest to the peripheral flange 7';
The other end of this plate is provided with a tongue piece 15 bent at right angles, which is overlapped with the upper end of the vertical wall, and a bolt 17 is passed through the vertical wall and fixed to the vertical wall. It is characterized in that a recess portion 32 is provided which is spaced apart from the peripheral flange 7' of the ceiling wall.

ボルト付近のパネルを保護することができる。 In this manner, the present invention directly reinforces the upper end of the vertical wall and the periphery of the ceiling wall, that is, the corner portion formed by the vertical wall and the ceiling wall.
In this corner part, the vertical wall and the ceiling wall are overlapped and simply connected with bolts, and the horizontal external force deforms it like a link connection. The parts closest to the joint are diagonally connected by the stiffeners, so that the vertical wall, the ceiling wall, and the stiffeners form a triangle with small corners. Therefore, even if a large horizontal load is applied during an earthquake, the included angle between the vertical wall and the ceiling wall will not change significantly, and the connecting bolt between the vertical wall and the ceiling wall and the panel near this bolt will be protected. be able to.
