Description

A PC wall structure having an integral vertical joint and a method for converting an external wall of the basement to a PC using the same {MODULARIZED MONOLITHIC JOINT PC WALL AND BASEMENT OUTER WALL PC CONSTRUCTION METHOD}

The present invention relates to a PC wall structure having an integral vertical junction and a method for converting an external wall of an underground layer to a PC method using the same, and more particularly, it minimizes the quantity of temporary construction while securing stability against horizontal force when constructing an external underground wall, and at the same time construction of two or more floors It relates to a PC wall structure having an integral vertical joint of a new structure capable of reducing construction cost and construction time by making this possible, and a method for converting an external wall of the basement to a PC using the same.

Recently, in constructing structures, each structure is produced as PC (Precast Concrete) in the factory in advance, transported to the site, arranged according to the design location, and then concrete is poured on the site to integrate each PC.

As a construction method for integrating the PC wall, the upper view of FIG. 1 is a view showing a conventional joint site formwork installation type. Referring to this, the existing construction method for unifying the PC wall consists of horizontal reinforcing bars 3 and 3 penetrating the PC wall 2 in the longitudinal direction, and sets a predetermined interval between the continuous PC walls 2 to set a predetermined distance. After overlapping the horizontal reinforcing bars (3, 3') protruding from the left and right of each PC wall (2), install the formwork (4) in a predetermined space and pour the on-site concrete (5) Thus, the continuous PC wall 2 is integrated.

However, in this PC wall integration construction method, a separate formwork (4) is additionally installed in a predetermined space formed between the continuous PC walls (2), the on-site concrete (5) is poured, and the poured on-site concrete (5) ) is completed, the process of dismantling the installed formwork (4) again takes a long time, and the amount of temporary construction due to the formwork (4) installation increases and process interference occurs, so the advantages of the PC wall (2) There are problems that cannot be saved.

Next, the lower view of FIG. 1 is shown for the conventional horizontal reinforcing bar U-shaped overlap joint form, and concave grooves 2' concave inwardly are formed at both ends of the PC wall 2, and U-shaped reinforcing bars from the both ends. (6) is formed to protrude.

That is, in the continuous installation of the PC wall 2, the U-shaped reinforcing bars 6 protruding from both ends of the PC wall 2 are configured to continuously overlap in the vertical direction, and the central portion of the overlapping U-shaped reinforcing bars 6 By assembling the vertical joint reinforcing bar 7 on the and pouring the on-site concrete 5 into the concave grooves 2' configured at both ends of the PC wall 2, the continuous PC wall 2 is integrated.

However, the above method is difficult to apply because it is impossible to assemble it with a horizontal connection part at the same time as a vertical reinforcing bar sleeve. Also, when changing to a roof type to enable the assembly of vertical joint reinforcing bars, there is a problem in that it is difficult to secure the rigidity of the integral wall.

Therefore, in recent sites, a PC wall structure having an integrated vertical joint with a new structure with improved stability by minimizing the amount of field work and temporary construction and securing the rigidity of the integrated PC wall and the basement external wall PC to which the PC wall is integrated. There is a need for a chemical method.
