[0020] Next, the operation of the elastic resin layer 4. First, even when the retaining wall is constructed by arranging the formwork panels 1 of the first embodiment on the wall, the poured concrete C shrinks with solidification. However, when the elastic resin layer 4 is compressed by the load at the time of placing the concrete C and the concrete C solidifies and contracts, the elastic resin layer 4 adheres to the concrete C and is restored by its own elastic force. As shown in FIG. 1A, no gap G is generated between the elastic resin layer 4 and the solidified concrete C.
Even if the gap G occurs, the gap G is very small. [0021] However, the rainwater in the small gap G entering between concrete C which solidified elastic resin layer 4, be frozen, such as rain water in the gap G, as shown in FIG. 1 (b) When the elastic resin layer 4 is compressed, the stress caused by the freezing of rainwater or the like that has entered the gap G does not act on the wall-form construction form panel 1, and cracks R are formed on the wall-form construction form panel 1. No longer occurs. Incidentally, when the melts frozen rainwater gap G, the elastic resin layer 4, FIGS. 1 (a)

[0022] Thus, rainwater that has entered the small gap G between the concrete C which solidified backside wall construction for formwork panel 1 is frozen, even if repeated the frozen rain dissolves, elastic resin When the layer 4 is elastically deformed, the stress caused by the freezing of rainwater or the like that has entered the gap G does not act on the wall panel 1 and the crack R is generated on the wall panel 1. At the same time, there is no possibility that a part or the whole of the wall panel 1 will fall off, and the scenery decorated with the wall panel 1 can be maintained. The elastic resin layer 4 provided on the back surface of the wall-building form panel 1 has good adhesiveness to a sealing material for sealing between the wall-building form panels 1, so that high-fluidity concrete or the like is used. Even if it is provided, there is no need to worry about leakage of the highly fluidized concrete or the like from between the wall panels 1. Furthermore, since the elastic resin layer 4 is provided on the back surface of the wall panel 1, moisture such as cast concrete C flows through the capillary of the wall panel 1 to the surface of the wall panel 1. Because it does not penetrate, that is, the elastic resin layer 4 blocks the permeation of moisture to the surface of the wall-building formwork panel 1, so that the floating lime or the like precipitates on the surface of the wall-building formwork panel 1. Does not occur, and the surface of the wall panel forming form panel 1 is not stained, and the landscape is not damaged.

By bonding to the REIT and restoring with its own elastic force,
A gap is created between the elastic resin layer and the solidified concrete
No longer. And since the elastic resin layer was provided on the back of the wall construction form panel, the rainwater that entered between the back of the wall construction form panel and the solidified concrete freezes, and the frozen rain water melts. be repeated, by elastic resin layer is elastically deformed, the stress is wall-building formwork panel due to such penetration rainwater freezes between concrete solidified backside for formwork panel wall construction Since it does not work, cracks do not occur on the wall construction form panel, and there is no possibility that part or the whole of the wall construction form panel will fall off, and the scenery decorated with the wall construction form panel will be eliminated. Can be maintained. The elastic resin layer provided on the back surface of the wall panel for forming a wall has good adhesiveness to a sealing material for sealing between the wall panels for forming a wall. In addition, there is no need to worry about leakage of highly fluidized concrete or the like from between the wall construction form panels.
Furthermore, since the elastic resin layer is provided on the back surface of the wall-building form panel, moisture such as cast concrete does not penetrate into the surface of the wall-building form panel through the capillary tube of the wall-building form panel. In other words, since the elastic resin layer blocks the penetration of moisture to the surface of the wall-building formwork panel, the efflorescence phenomenon of floating lime or the like that precipitates on the surface of the wall-building formwork panel does not occur, and The surface of the formwork panel is not stained, and the landscape is not damaged.
