、コンクリート打設を行う手段がある。In addition, as another means, as shown in Fig. 4, a conch IJ
-1. There is a method for pouring concrete by supporting the load during pouring with the rigidity of the steel roof itself.

、費用が嵩むという問題点がある。In this case, the rigidity of the steel roof is ensured by the roof plates 5 and roof ribs 6, so the
1. Cross-sectional rigidity is required to be 15 to 20 times higher than the roof rigidity without coating.'n! There is a problem in that a lot of materials are required for the 4-piece roof, which increases the cost.

Seventh, it is necessary to provide a construction method that can shorten the construction period and reduce costs by simply increasing the pressure in the storage tank to match the concrete covering load.

リート打設を行うことを特徴とするものである。Means for Solving the Problems] The construction method of the concrete/crete roof for storage tanks of the present invention which solves the problems of the prior art is
-1- When constructing a covered roof structure, after completing the installation of the W4 roof, a pressure approximately equal to the concrete load to be poured and covered on the outer surface of the steel roof is applied in the storage tank, and the concrete load is applied by applying the pressure inside the storage tank. This system is characterized by the fact that concrete is placed while supporting the concrete.

Figure 2, a schematic diagram of the storage tank, shows a partially enlarged view of the roof structure. Figure 1 shows a storage tank 1 consisting of a concrete structure.
On the other hand, the steel roof 12 constructed by conventional means has been completely installed and is covered with reinforcing bars 1 and 13.

。(7) After completing the installation of the steel roof 12, high-pressure air is fed into the storage tank 11 using a compressor (not shown), etc., until the pressure P in the storage tank becomes equal to or almost equal to the concrete covering load We. After applying pressure, or while applying pressure, reinforced concrete 13 is placed on the outer surface of the steel roof 12. After the installation is completed, the storage tank 11
Construction is completed by releasing the pressure inside and bringing it to atmospheric pressure.
