It is characterized by being installed.

The step A) is a step of erecting a frame for an outer wall, and the first vertical frames 10A having fitting grooves 11 are set at equal intervals to the left and right and fixed and installed on the pedestal.

The step B) is a step of installing the second PDP panel 20B into the first vertical frames 10A where the installation is completed.

As the first vertical frame 10A for the outer wall, when the vertical frames 10 having the same lengths of the flanges 12 and 13 and without the upper support 15 are installed, the second PD panel 20B is vertically framed. (10) can be installed by sliding in the longitudinal direction,

Alternatively, if the length of the flanges 12 and 13 is different as the first vertical frame 10A for the outer wall, and the vertical frame 10' having the support 15 formed at the upper end is installed, the second PD panel 20B After inserting one end of the first into the fitting groove 11 of the one side vertical frame 10', the left and right side ends of the second PD panel 20B are turned to one side and tilted, so that the flange 12, 13 Using the space formed by the length difference (D1) of the second PD panel (20B) (the other end of the other vertical frame (10') of the fitting groove 11, and then the second PD panel (20B) The inner plate can be pushed outward to fit the flanges 12 and 13.

The step C) is a step of fixing and installing the first horizontal channels 30A on the outer plate 22 of the second PD panel 20B, which has been installed, at the same intervals.

When the vertical frame 10 is installed as the first vertical frame 10A, the first horizontal channel 30A is fixed relatively vertically and inserted between the fitting grooves 11, and then the first horizontal channel 30A is fixed. After the first horizontal channel 30A is laid down in a horizontal or diagonal direction at a height to be set, the second support portions contacting the second flanges 13 and 13 are fastened with fixing bolts to connect the first horizontal channels 30A to the second. Fix and install on the outer surface of the PD panel 20B,

When the vertical frame 10' is installed as the first vertical frame 10A, the first horizontal channel 30A in the same manner as the second PDP panel 20B using the opposite opening in which the second PDP panel 20B is installed. By installing and fixing the first horizontal channels 30A on the outer surface of the second PD panel 20B, the installation of the outer wall W is completed.

Next, as shown in Figure 5, in the construction method of the prefabricated PDF water tank according to the present invention,

The partition (P),

a) installing the first and second flanges 12, 13, the web 14, and the second vertical frames 10B for partitions having a fitting groove 11 spaced apart at predetermined intervals from side to side;

b) installing the third PDP panel 20C for partitioning into the fitting groove 11 so that both ends are supported on the inner surface of the first flange 12 of the second vertical frame 10B;

c) Each second horizontal channel (30B) is coupled to the third PD panel (20C) by inserting a plurality of second horizontal channels (30B) for partitions in a diagonal direction to the fitting groove (11) so as to be spaced apart at predetermined intervals. Fixing by;

d) Inserting the fourth PDP panel 20D composed of the first powder 24 and the second powder 25 separated left and right into the fitting groove 11, both ends of the fourth PDP panel 20D It is installed, including; installing to be supported on the inner surface of the second flange (13),

In the step d), the outer ends of the powder bodies 24 and 25 are inclined to be inclined in the vertical direction with respect to the first powder body 24 and the second powder body 25, respectively. ), after inserting into the fitting groove 11, the installation of the fourth PD panel 20D is completed by pushing the inner ends of the powders 24 and 25 in contact with the inside of the partition P.

The a) step is a step of erecting a frame for the partition (P), the second vertical frame (10B) having a fitting groove (11) is erected at equal intervals left and right, fixed to the bottom plate and installed.

The step b) is a step of installing and installing the third PDP panel 20C into the second vertical frames 10B where the installation is completed.

The specific installation method of the third PDP panel 20C according to the vertical frames 10 and 10' used as the second vertical frame 10b is as described in the second PDP panel 20B of the outer wall W same.

The step c) is a step of fixing and installing the second horizontal channels 30B on the inner plate 21 of the third PD panel 20C, which has been installed, at the same intervals.

The specific installation method of the second horizontal channel 30b according to the vertical frames 10 and 10' used as the second vertical frame 10b is the same as described in the first horizontal channel 30a of the outer wall W. .

The step d) is a step of completing the partition P by installing the fourth PD panel 20D.

The fourth PDP panel 20D may also be formed as a single panel like the third PDP panel 20C, and may be installed by sliding or sliding the panel in the longitudinal direction.

In the present invention, the second support portion 32 of the second horizontal channels 30B is spaced apart at a predetermined distance to a portion where the inner plate 21 of the fourth PD panel 20D comes into contact with the second support portion ( The surfaces formed by the 32) are uneven, and the remaining space of the fitting grooves 11 in which the third PDP panel 20C and the second horizontal channel 30B are installed is also very narrow, so that the single type second PDP is described in the above manner. Panel installation is difficult.

Accordingly, the fourth PD panel 20D is composed of two powders 24 and 25, so that each powder 24 and 25 are staggered from side to side in step d). (24) After first fitting the outer end of the (25) into the fitting groove (11), the inner ends of the protruding powders (24) (25) are pushed inward into the partitions so that both ends of the powder (24) (25) Fitted to the inner surface of the flange 13, the installation of the fourth PD panel 20D is completed.

That is, the right end of the first powder 24 is fitted in a diagonal shape to the fitting groove 11 of the right second vertical frame 10B, and the left end of the second powder 25 is used using the space formed thereby. After aligning and fitting the fitting groove 11 of the left second vertical frame 10B in a diagonal shape,

The first and second locking portions 24a and 25a of the first and second powder bodies 24 and 25 are alternately aligned, and then the first and second locking portions 24a and 25a are pushed inward, As the first and second powders 24 and 25 are pushed to the left and right due to the second support 32 of the second horizontal channel 30B, the powders 24 and 25 are flatly aligned, so that the Installation is complete.

According to the present invention, the third and fourth PD panels 20C and 20D and the second horizontal channel 30B are installed in the second vertical frame by installing the separated powders 24 and 25 in the above-described manner. By accurately fitting and installing between (10B), the construction of the partition P can be carried out more easily and quickly.

In addition, the prefabricated PDF water tank according to the present invention, even if the waterproof pouch made of synthetic resin of vinyl such as PE sheet is covered inside the water tank, the bolt fixing the second horizontal channel 30B is in contact with the waterproof pouch partition P ) Is not exposed to the outer surface of the waterproof pouch is not damaged.

In the above, in explaining the present invention, a prefabricated PD F water tank having a seismic function and a construction method thereof have been mainly described with reference to the accompanying drawings, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art And substitutions should be construed as falling within the protection scope of the present invention.
