に連結する。This piping unit Pd is a pipe body divided in accordance with the thickness of the above-mentioned deck beam unit A, and the pipe body is divided into the upper part of the hEE force suppression chamber.
The deck beam unit A and piping unit P are installed in advance at the factory etc., as shown in Figure 11. However, it is also possible to transport this to the site, or have a Detsuki Beam unit person near the site take the piping unit P, but in either case [7] the piping unit P is After configuring the deck beam units A corresponding to the number of divisions, install the 8 unit A at the site and install the piping unit P in this way. Beam unit A% 7.2174 As shown in the figure, the m1 secondary stage beam is installed on both side walls I A * 1)) of the structure 1 for housing the beam unit A%7.2174, which has already been constructed. Then connect them to each other, and further connect the piping and knit P turns to each other.

、After completing the connecting chart for the deck beam unit A and the piping unit P, place the deck plate 14 on top of the deck beam unit A, and place the necessary arrangements on it. After making the striations, the ceiling concave +1-115 is cast to form the ceiling of the pressure suppression chamber B, and the necessary piping P' is installed above the pressure suppression chamber (14 and σ). As explained above, the method for installing piping according to the present invention is to divide the ceiling deck beam of the pressure suppression chamber into a beam unit, and to install this deck beam unit. This is a construction method in which a piping unit) is installed in advance in the pressure suppression chamber and a deck beam unit is installed to run the piping inside the pressure suppression chamber, so the on-site piping work t and the connection of these piping units ff = q are required. Therefore, the piping forms that can be prepared at the site are extremely simple, and since the deck beams and piping are unitized in this way,
At the site, it can be constructed in a block format, and time-consuming temporary equipment such as temporary transport 1-1 and transport rails can be eliminated, so labor-saving piping work alone can shorten fk (the construction period is shortened accordingly). It has excellent effects such as being able to use cloth,
