It is a front view explaining 1st Embodiment of this retaining wall construction method. In these figures, reference numeral 21 denotes a foundation formed by casting concrete, and 31 denotes a support angle formed by embedding the lower end of a metal angle in the base 21, and the support angle 31 is used for retaining wall construction. It is erected at a half interval in the width direction of the formwork panel 1, that is, at an interval of 450 mm.
Reference numeral 41 denotes a sealing material for sealing the back side of the seam of the wall panel forming form panel 1, which prevents concrete or the like from flowing out to the front side or infiltrating thin or the like from the front side. 51 indicates a filler, and 61 indicates a backfill material.

Next, a case in which the retaining wall is constructed by arranging the formwork panels 1 for wall construction will be described. First, the foundation 21 is cast into a width for constructing the retaining wall, and the support angles 31 are erected on the foundation 21 at intervals of 450 mm. next,
Each hook 3 on the lower side which made the wall form forming panel 1 horizontally long
The lower portion 12d of the connecting fixture 11A is fitted into the inside of the hook 3 and the lower portion 12d of the connecting fixture 11 is fitted into each upper hook 3.

Then, the wall panel forming form panel 1 is erected from the support angle 31 by, for example, 300 mm, and the separators 13 are set to be in a state of being perpendicular to the wall surface forming form panel 1. That is, the other end sides of the connecting fixtures 11 and 11A are fixed to the angle 31 by welding. By sequentially performing this work in the horizontal direction (horizontal direction), the first-stage wall-form building form panels 1 can be arranged side by side as shown in FIGS.

Next, the second-stage wall-building formwork panel 1 is を of the width of the first-stage wall-building formwork panel 1.
Then, the upper part 12u of the connecting plate 12 is fitted into the lower hooks 3 of the second stage while sliding the upper portion 12u of the connecting plate 12 against the back surface of the second form wall panel 1. After this work is sequentially performed in the horizontal direction, the lower portion 12d of the connecting plate 12 is fitted into the hooks 3 on the upper side of each of the second-stage wall forming form panels 1, and the second-stage respective wall forming The other end side of each connecting fixture 11 is welded and fixed to the angle 31 so that the form panel 1 stands upright, and as shown in FIGS. Ones can be stacked and arranged side by side.

The work of stacking the second-stage wall forming form panels 1 can be performed without using a scaffold from the back side of the wall-side forming form panel 1, for example, the fourth-stage wall forming form panel. After the form panels 1 are stacked, the back side of the seam of the form wall panel 1 is sealed with a sealing material 41, and then, as shown by a two-dot chain line in FIG. By filling and hardening the back side of the construction form panel 1, the vertically arranged wall construction form panel 1 and the solidified concrete are integrated.

Thereafter, as shown in FIG. 4, for example, as shown in FIG. 4, the work of filling the concrete (filling material 51) after sequentially stacking the three-tiered formwork panels 1 and sealing them with the sealing material 41 is performed. Walls can be built.

In addition, as shown in FIG. 4, the front surface of the first-stage wall form building form panel 1 is backfilled with a predetermined backfill material 61 at an appropriate time.

As described above, according to the first embodiment of the present invention, a retaining wall can be constructed using the wall construction frame panel 1 without installing a temporary scaffold. And since a retaining wall can be constructed without installing a temporary scaffold, a construction period can be shortened and construction cost can be reduced. In addition, since a portion on the back surface side of the wall panel forming form panel 1 serving as a retaining wall or on the cured filler 51 can be used as a scaffold, work can be performed safely and work efficiency can be improved.

FIG. 6 is a plan view illustrating a second embodiment of the retaining wall construction method of the present invention, and FIG. 7 is a front view illustrating the second embodiment of the retaining wall construction method of the present invention. Note that the second embodiment is arranged so that it is located at the center of two hooks 3 that are continuously arranged in the left-right direction and that constitute one set, that is, 90 hooks.
The difference from the first embodiment is that the column angles 31 are erected on the foundation 21 at intervals of 0 mm.

When a retaining wall is constructed in the second embodiment,
As shown in FIG. 6, the only difference is that the bent other end of the separator 13 is welded to the support angle 31.
Otherwise, a retaining wall can be constructed by performing the same operation as in the first embodiment.

Therefore, in the second embodiment, the same effect as in the first embodiment can be obtained. Further, since the support angle 31 is erected at the center of the two hooks 3 that are continuously arranged in the left-right direction that constitute one set, the number of the support angles 31 is reduced, so that the construction cost can be reduced. . In addition, support angle 31
The work becomes easy and the work efficiency is improved by widening the interval of.

In the embodiment described above, the form panel body 2 excluding the hooks 3 has a height of 300 mm, a width of 900 mm, and a thickness of 35 mm, but is not limited to this size. Absent. In addition, hook 3
However, the connecting member may be formed of an angle material having a through hole through which the anchor bolt is inserted, by forming a part of the male screw and projecting the anchor bolt.

In the above description, the form panel 1 for constructing a wall is made of concrete. However, a natural stone may be cut out in a plate shape and a connected member such as a hook 3 may be fixed. Further, the example has been described in which the other end side of the separator 13 is fixed by welding to the angle support 31.
For example, the other end of the separator 13 may be fixed to the angle support 31 using a fixing metal.

In the second embodiment, an example has been described in which the support angle 31 is erected at the center of two connected components that are continuously arranged in the left-right direction. The same effect can be obtained even when the column angles 31 are erected between the connecting tools. Here, the two connected components continuously arranged in the left-right direction are the two connected components provided on the adjacent two wall construction form panels 1 as shown in the first row of FIG. 7 and two connected components provided on one wall construction frame panel 1 as shown in the second row of FIG. 7.

As described above, according to the present invention, a retaining wall can be constructed using a wall construction form panel without installing a temporary scaffold. And since a retaining wall can be constructed without installing a temporary scaffold, a construction period can be shortened and construction cost can be reduced. In addition, since the portion on the back side of the wall construction frame panel serving as a retaining wall or on the cured filler can be used as a scaffold, the work can be performed safely and the work efficiency can be improved. Furthermore, since the columns are erected between the two connected components that are continuously arranged in the left-right direction or substantially at the center of one set, the number of columns is reduced,
The construction cost can be reduced, and the spacing between the columns (at the approximate center, the spacing is almost equal)
Work is easy and work efficiency is improved.
