As shown in FIGS. 1 to 3, a plug-in type simple concrete wall 10 according to an embodiment of the present invention is provided with a cane-shaped support member 11 on the back surface and concrete columns 12 arranged at predetermined intervals. A concrete insert 13 is installed between the concrete columns 12, and a girder 14 is installed on the top of the concrete columns 12. These will be described in detail below.

The concrete column 12 has vertical grooves 15 and 16 on both sides,
It is firmly connected to the back supporting member 11 having a cane-shaped support member by an inverted V-shaped connecting rebar 17. In addition, the cane-shaped support member
A drop-out preventing projection 18 is provided on the lower part of 11 to easily adhere to the earth deposited on the back side.

As shown in FIG. 4, the plug-in concrete plate 13 has a pair of hanging metal fittings 19 protruding from the upper part except the uppermost plug-in concrete plate 13a, and when stacked on the lower part,
A small hole 20 into which the hanging fitting 19 is fitted is provided.

Both sides of the concrete insert plate 13 are slightly thinned to form vertical groove fitting portions 21 and 22.

Said girder 14 is made of a member having a quadrangular cross section, is provided with a mounting hole in the lower portion according to the pitch of the concrete support columns 12, and is provided on the top of the concrete support column 12 in front of the upper ends of the vertical grooves 15 and 16. It is supposed to be covered.

Therefore, when assembling the plug-in type simple concrete wall 10, first, dig a hole of a predetermined size at a predetermined pitch in the ground, and tilt the concrete support column 12 slightly to the back side so that the lower part of the cane-shaped support member 11 is on the ground. The lower part of the girder is buried and the girder 14 is placed on the upper part. This allows the concrete columns 12 to be supported in place.

Next, the vertical groove fitting portions 21 and 22 on both sides of the inserted concrete plates 13 and 13a are connected to the vertical groove 1 of the adjacent concrete support columns 12.

Reinforcing bars are provided on each concrete part.

[Effect of device]

As is clear from the above description, the plug-in type simple concrete wall according to the present invention is fitted into the top of the front side of the concrete pillar from the end of the vertical groove, and the concrete pillar is connected to prevent lateral movement. Since the girder is provided, the insertion concrete plate can be inserted and replaced even when the insertion simple concrete wall is installed on the site.

Further, since the gaze beam is provided on the top of the concrete pillar, the concrete pillar can be laterally fixed to construct a high wall. Further, in assembling, since the columns can be fixed by using the gaze beam, there is an advantage that insertion of the concrete insert plate is extremely easy.

Further, since the upper part of the cane-shaped supporting member is connected to the concrete pillar through a connecting rebar, and the retaining protrusion is provided at the lower part thereof, the cane-shaped supporting member is attached to the soil on the back surface. In addition to being able to be fixed, the connection strength of concrete columns can be increased.

Furthermore, the insert concrete plates other than the insert concrete plate arranged at the uppermost part are provided with a pair of hanging metal fittings on the upper part thereof, and the lower part is provided with a hanging metal fitting for suspending the insert concrete plate arranged at the lower part. Since there is a pair of small holes into which the metal fittings are inserted, it is possible to stack the concrete insert plates in an orderly manner, and furthermore, it is possible to hang the concrete insert boards in good balance by using a pair of hanging metal fittings for carrying them. it can.

Since both sides of the inserted concrete plate are stepwise thinned to form a vertical groove fitting portion which fits into the vertical groove of the concrete support pillar, it is possible to increase the plate thickness of the portion to which the bending moment is applied by the earth and sand. As a result, sufficient strength can be obtained, and since the vertical groove fitting portions on both sides are thin, it is possible to reduce the thickness of the concrete column.
