By installing them as one unit, it is possible to shorten the construction period of the entire storage tank. Furthermore,
Since the two roof structure parts with a half-dome structure are constructed in different places, no work place near the tank body is required during that period,
In addition, since the roof structure is divided into two half-dome structures, there is no need for a large work area in one place even after transporting to the vicinity of the tank body, and there is even a work area of half-dome size on both sides of the tank body. If possible, it will be possible. Therefore, the working period near the tank body is short, and the roof part can be constructed without requiring a large space in one place.

A method of laterally moving the roof structure 3 to a will be described with reference to the plan view on the left side of the paper of FIG. 4. First, two carriages 11 that laterally move on both sides of the cradle 8 on which the roof structure 3 is placed. The trolley 11 is mounted via wheels 17 on the temporary rail 10 laid in advance. FIG. 6 is a side view of the carriage 11 that laterally moves. A hydraulic jack 18 is mounted on the carriage 11 and serves as a mechanism for extending the cylinder 20 upward. Two laterally moving carts 1
After arranging 1 on the right and left sides of the receiving stand 8, the receiving beam 12 connecting the two carriages 11 is placed on the upper part of the hydraulic jack 18, the hanging wire 19 is lowered from the center thereof, and the lower end thereof is attached to the hanging bracket 9. In the portion of the cradle 8 which is responsible for the three roof constructions of the halved dome structure, the dolly 11 and the beam 12 are provided.
After all the mounting of the suspension wire 19 is completed, the cylinders 20 of the hydraulic jack are simultaneously extended upward, the entire roof structure 3 is suspended, and the suspension structure 8 is levitated. After the entire floating is completed, the cradle 8 is lifted from the temporary rail 10 and removed by a crane waiting nearby. Figure 4
In the above, after the removal of the three receiving stands is completed, all the carts 11 are driven to run on the temporary rails 10 all at once, and the roof structure 3 having the half-dome structure is placed at the upper opening 1a of the tank 1.
To move sideways. After the lateral movement to the installation position of the upper opening 1a is completed, the cylinders 20 of the hydraulic jack 12 mounted on the truck 11 are simultaneously contracted to lower the entire roof structure 3 to the upper surface of the tank body 1 at a plurality of places. It is mounted and supported on the installed mounting base 21 and fixed by installation. Figure 8
Is a side view thereof. After this installation and fixing is completed, the cylinder 20 of the hydraulic jack 18 is further contracted to loosen and remove the suspension wire 19, and then the carriage 11 is removed by a crane or retracted rearward. The same operation is performed on the half-dome structure roof structure 3 on the opposite side of the tank body 1,
It is installed in the upper opening 1a of the tank body 1. After that, the roof bones 22 and the roof plates 23 that connect the two half-dome structure roof components 3 to each other are attached by a mobile crane to complete the integral dome-shaped roof structure 2 and finish the installation.
