However, in the wall surface construction method and the wall surface structure disclosed in the above-mentioned conventional patent document 1, when the wall is constructed by stacking the concrete panels, the bolts are inserted into the bolt insertion holes of the attachment plate and the concrete panel from the attachment plate side , It is necessary to fasten each panel by screwing the nut to the opposite side. This operation is required for two attachment points per attachment plate, and it is necessary to maintain the state that the upper panel is placed on the lower panel. For this reason, in the conventional wall surface construction method and wall structure using a plurality of such attachment plates, it takes a very long time to construct the wall surface, and the operation efficiency is not good.

Further, since each panel is tightly connected to each other by a bolt, the flexibility is lowered. Therefore, when the wall surface constructed by the conventional wall surface construction method and the wall surface structure is used for a wall surface of a flexible structure such as a reinforced soil construction method, embankment or the like behind the panel is deformed or settled and the load is concentrated on the back surface of the panel When applied, panels that are tightly connected together by bolts follow them and can not move. As a result, a large load is locally applied to a part of the panel constituting the wall surface, and the panel may be damaged.

According to an aspect of the present invention, there is provided a panel main body comprising: a plurality of panel main bodies arranged in a plurality of lateral directions, each having a height different from a top end portion thereof, A method of constructing a wall by stacking up the panel main body to a predetermined height by raising the upper end of the panel body to a height higher than the upper end of the side panel body,

At the same time, the anchor bolts 4 on the lower side of the rearmost panel 1A ₁ and the rear side of the panel 1B are directly welded to the fixing member 52 and the anchor bolts 4 on the rear side of the panel 1A ₁ , The conductive member 51 is welded between the conductive member 52 and the conductive member 52. By this operation, the conduction to the front side of the panel ₁ IA and the panel 1B at the lowest level is prevented.

Next, the heights of the upper ends are alternately changed so that the lower end of each of the panels 1A ₁ , 1B of the first stage located at the lowest end arranged in the plurality of horizontal directions, (1A _21), the first becomes built up by matching the panel (1B) and side end of the second stage, stacked two panels of the second stage panel (1A ₂₁₎ upper end side of the first end of the raised (1A ₁₎ the upper end of ≪ / RTI > The panel body 1a is piled up in the same manner as in the first embodiment. Then, with two anchor bolts (4) of the rear top of the panel (1A ₂₁₎ of the second end panel (1A ₂₁₎ and between the second end with the anchor bolt (4) and the fastener (52) of the back bottom of the fastener ( 52 are welded to each other. By this operation, the conduction to the front surface of each panel 1A ₂₁ of the second stage is prevented.

Next, different from the height of the upper end turns, a first end arranged in a plurality of horizontal directions and two each of the panels of the first stage _{(1A 1), (1A 21} ) , each panel of the in the first stage a low upper (1A ₁ , The second stage panel 1A ₂₂ is piled up in such a manner that the first stage panel 1A ₁ and the side end portions thereof are aligned with each other and the upper end of the stacked second stage panel 1A ₂₂ is stacked on the second stage Is higher than the upper end of the side panel 1A _{21 of the main} body 1A.

By this operation, the conduction to the front surface of the second stage of the panel 1A ₂₂ is prevented.

Next, the heights of the upper ends are alternately changed so that the upper ends of the respective panels 1A ₂₁ , 1A ₂₂ of the second stage arranged in the plurality of lateral directions are arranged in the lower panel 1A ₂₁ , 1A ₃₁ are stacked in such a manner that the respective panels 1A ₂₁ and the side ends of the second stage are aligned with each other and the upper end of the stacked third stage panel 1A ₃₁ is stacked on the side of the second stage side panel 1A ₂₂ Is higher than the upper end. Then, the three anchor bolts (4) on the top back surface of the second end panel (1A ₃₁₎ the anchor bolts (4) of the back bottom of the fastener 52, and between the third end panel (1A ₃₁₎ in between the fastener ( 52 are welded to each other. By using this repeating operation, the conduction of the front side of the three panels ₍₃₁ 1A) of the second stage is prevented.
