As shown in FIG. 4A, first, the steel wire 4 is disposed through the steel wire fastening holes 111 of the plurality of basic integrated type PC walls 10 formed by standing in a row, and is tightened after being strained.

At this time, on the side end front surfaces of the base integrated type PC wall 10 corresponding to the one end portion and the other end portion of the upright wall body 1, the fixing holes 117 and 118 are blocked out so as to intersect with the steel wire fastening holes 111 So that one end and the other end of the steel wire 4 can be easily fixed and fixed.

 Thereafter, as shown in Figs. 4B to 4C, the steel wire 4 is pulled out from the steel wire fitting hole 112 of the (n + 1) th integrated integral PC wall 10 in order from one side to the other side of the upright wall 1 The n and n + 1 th integrated seamless PC walls 10 are fixed to each other by fixing the cut and cut steel wire 4 at the steel wire fitting 112 so that the resistance against vertical shear deformation is increased .

The steel wire 4 is inserted into the steel wire fastening hole 111 of each base integral type PC wall body 10 so that the steel wire 4 is cut in a stepwise manner so that the steel wire 4 is cut into the steel wire fastening hole 112, The wedge cone 41 is sandwiched between the steel wire 4 and the steel wire 4 so that the steel wire 4 is fixed to the wedge cone 41 at the time of cutting the steel wire 4 .

Thereafter, as shown in Fig. 5, a foundation slab 5 is formed under the base integral-type PC wall 10 (e).

The foundation slab 5 connects the reinforcing bars for forming the foundation slab 5 with the connecting reinforcing bars 121a protruding from the rear joining portion 121 of the base integrated type PC wall 10, Thereby forming the slab 5.

Then, as shown in FIG. 6, the bottom plate slab 6 of each layer is sequentially installed from the bottom to the top (FIG. 6F).

The base integrated PC wall 10 of the upright wall 1 is provided with a step by step at every predetermined height of the wall plate 11 and the concrete is laid and cured so that the bottom plate slab 6 of each layer is constructed.

At this time, when the reinforcing bar embedding box 13 is buried at a certain height of the rear face portion where the bottom plate slab 6 is to be formed in the base integral type PC wall 10 and the mold of the bottom plate slab 6 is installed, The reinforcing bars 131 may be integrally formed by connecting the reinforcing bars to the reinforcing bars to form the bottom plate slabs 6 of the respective layers. In particular, The slab 14 can be stably mounted on the mounting jaw 14 when the dowel is installed to place the bottom plate slab 6 of each layer.

As shown in the figure, the reinforcing bars 131 may be formed by connecting the reinforcing bars 131 such that one end of the reinforcing bars 131 is embedded in the wall plate 11, And a lid is formed on the surface thereof, so that the lid can be removed and the connecting reinforcing bar 131 formed inside can be unfolded.

Finally, as shown in Fig. 7, the roof slab 7 is completed and completed (g).

In order to construct the roof plate slab 7, a mold is installed at the upper end of the base integrated type PC wall 10 and the concrete is laid on the upper end of the base integrated type PC wall 10 in such a manner that a lower end is embedded A connecting rebar may be constructed.

In the method of constructing a building using the integrated monolithic PC wall as described above, the PC wall in which the monolithic foundation is formed is erected so that the outer wall of the monolith can be constructed at the same time as the foundation, There is a very effective effect that the processes of cutting and fixing the steel wire so as to integrate the adjacent PC walls together after the adjacent PC walls are strained by the steel wire are integrated with uniform tension force between the PC walls.
