Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described embankment structure, the tie rods are horizontally extended from the upper end side of the wall to reach the ground side, and the positional relationship of the connection points of the tie rods on each of the wall and the ground side is uniquely defined. Therefore, in the vicinity of an area where obstacles such as existing water channels or trestle bridges exist on the ground, there is a problem that the wall and the ground side cannot be connected by tie rods due to interference with these obstacles.

[0005] The present invention has been made to solve such problems, and its object is to provide a technique for preventing a situation where the wall and the ground side cannot be connected by tie rods even when there are obstacles on the ground.

Means for Solving the Problems

[0006] The connecting structure according to the present disclosure is an embankment structure having a wall body provided at a position facing a ground wall surface formed by the ground, a tie rod connecting the wall body and the ground wall surface, and an embankment material filled between the ground wall surface and the wall body, wherein the connecting structure for connecting the tie rod to the wall body and the ground wall surface is such that the connection angle between the wall body and the tie rod is variable, and / or the connection angle between the ground wall surface and the tie rod is variable. [Effects of the Invention]

[0007] According to this disclosure, since the connection angle between the wall and the tie rod, and the connection angle between the ground wall and the tie rod, or both, are configured to be variable, the positional relationship of the points where the tie rod is connected in either the wall or the ground wall, or both, can be arbitrarily changed. As a result, even if there are obstacles in the ground, the tie rod can be connected to the wall and the ground wall, respectively, while avoiding these obstacles. [Brief explanation of the drawing]

[0009] Hereinafter, one embodiment of this disclosure will be described with reference to the drawings. (1) Overall structure

[0010] As shown in Figure 1, the embankment structure 1 is installed along a ground wall surface 110 formed by the ground 100, and comprises a wall body 10 positioned opposite the ground wall surface 110, a tie rod 20 connecting the wall body 10 and the ground wall surface 110, embankment material 30 filled between the ground wall surface 110 and the wall body 10, a connector 40 connecting one end of the tie rod 20 to the wall body 10, and a pressure plate 50 connecting the other end of the tie rod 20 to the ground wall surface 110.

[0011] The wall structure 10 comprises a plurality of columnar members 11 arranged at intervals along the ground wall surface 110, and a plate-like member 13 attached to the side of the columnar members 11 opposite to the ground wall surface 110 (the left side in the figure). In this embodiment, H-beams are used for the columnar members 11. The columnar members 11 are also arranged at intervals in a direction intersecting the plane of the paper in Figure 1.

[0012] The embankment material 30 is made of foamed resin.

[0013] The connector 40 realizes a connection structure in which the connection angle between the tie rod 20 and the wall 10 can be freely adjusted. As shown in Figure 2, the connector 40 comprises a first connecting member 410 provided on the side of the wall 10 facing the ground wall surface 110 (right side in the figure; the same applies hereafter), and a second connecting member 420 provided on one end of the tie rod 20.

[0014] Of these, the first connecting member 410 comprises a plate-like body 411 extending from the side of the wall body 10 facing the ground wall surface 110 toward the ground wall surface 110, a through hole 413 penetrating from the front to the back of the plate-like body 411, and a pair of extending regions 415 extending from the wall body 10 toward the ground wall surface 110 in a positional relationship with the through hole 413 in the direction of expansion of the wall body 10. In this embodiment, the first connecting member 410 is provided on the upper end side of the wall body 10. In this embodiment, plate-like members are formed as extending regions 415 at the upper and lower positions with the through hole 413 in between.

[0015] Further, as shown in FIG. 3, the second connecting member 420 includes an arcuate body 421 that extends in an arc shape with a circular cross section smaller than the through hole 413, and plate-shaped connecting portions 423 that connect the respective ends of the arcuate body 421. With the arcuate body 421 passed through the through hole 413, the respective ends of the arcuate body 421 are attached to one end side of the tie rod 20. In the present embodiment, the respective ends of the arcuate body 421 are fixed to the connecting portions 423, and one end side of the tie rod 20 is attached to the region of the connecting portion 423 sandwiched between these ends. In the present embodiment, a U-bolt is used as the arcuate body 421.

[0016] In the coupler 40 of the present embodiment, the plate-like body 411 is arranged in a direction extending along the vertical plane (the plane of FIGS. 1 and 2), and the arcuate body 421 is passed through the through hole 413 that penetrates the plate-like body 411 in the front-back direction. Thus, in the present embodiment, with the region of the arcuate body 421 passed through the through hole 413 as the rotation center, the tie rod 20 attached to the arcuate body 421 can rotate along the vertical plane, thereby realizing a connection structure in which the connection angle between the wall body 10 and the tie rod 20 can vary freely.

[0017] The pressure receiving plate 50 is fixed to the ground wall surface 110 by an anchor 51 embedded in the ground 100.

[0018] (2) Modified Example As described above, the embodiments of the present disclosure have been described. However, the present disclosure is not limited to the above embodiments, and various modifications are possible without departing from the gist of the invention. In particular, the plurality of modified examples described in this specification can be arbitrarily combined as needed.

[0019] For example, in the above embodiment, a configuration is exemplified in which the first connecting member 410 is provided on the wall body 10 and the second connecting member 420 is provided on one end side of the tie rod 20, so that the connection angle between the tie rod 20 and the wall body 10 can vary freely. However, in order to make the connection angle between the tie rod 20 and the wall body 10 variable, a configuration in which the second connecting member 420 is provided on the wall body 10 and the first connecting member 410 is provided on one end side of the tie rod 20 may be adopted as well. <A

[0020] In addition, in the above-described embodiment, a connection structure in which the connection angle between the tie rod 20 and the wall body 10 can vary has been exemplified. However, any connection structure in which the connection angle between the wall body 10 and the tie rod 20 can vary and / or the connection angle between the ground wall surface 110 and the tie rod 20 can vary may be used. That is, not only a connection structure in which the connection angle between the tie rod 20 and the wall body 10 can vary, but also a connection structure in which the connection angle between the tie rod 20 and the ground wall surface 110 can vary may be used, or a connection structure in which both of these connection angles can vary may be used.

[0021] Here, a connection structure in which the connection angle between the tie rod 20 and the ground wall surface 110 can vary can be realized by providing a first connection member 410 on either the other end side of the tie rod 20 or the pressure receiving plate 50, and providing a second connection member 420 on the other.

[0022] In addition, a connection structure in which the connection angle between the wall body 10 and the tie rod 20 can vary and the connection angle between the ground wall surface 110 and the tie rod 20 can vary can be realized by the following configuration. That is, a first connection member 410 is provided on either one end side of the tie rod 20 or the wall body 10, and a second connection member 420 is provided on the other, and a first connection member 410 is provided on either the other end side of the tie rod 20 or the pressure receiving plate 50, and a second connection member 420 is provided on the other.

[0023] In addition, in the above-described embodiment, the plate-like body 411 is arranged in a direction extending along the vertical plane, so that the tie rod 20 attached to the arc body 421 can rotate along the vertical plane with the region passed through the through hole 413 in the arc body as the rotation center. However, by arranging the plate-like body 411 in a direction extending along the horizontal plane, the tie rod 20 attached to the arc body 421 may be configured to be rotatable along the horizontal plane.

[0024] (3) Operational effects According to this embodiment, since the connection angle between the wall 10 and the tie rod 20, and the connection angle between the ground wall surface 110 and the tie rod 20, or both, are configured to be variable, the connection points with the tie rod 20 on either the wall 10 or the ground wall surface 110, or both, can be arbitrarily changed. As a result, even if there is an obstacle in the ground 100, the tie rod 20 can be connected to the wall 10 and the ground wall surface 110, respectively, while avoiding the obstacle.

[0025] Furthermore, in this embodiment, the connector 40, which includes the first connecting member 410 and the second connecting member 420, makes it possible to realize a connecting structure in which either or both of the connection angle between the wall 10 and the tie rod 20, and the connection angle between the ground wall surface 110 and the tie rod 20, can be freely adjusted.

[0026] In this connecting structure, the first connecting member 410 comprises a plate-like body 411 extending from the wall body 10 toward the ground wall surface 110 and a through hole 413 penetrating the plate-like body 411 from the front to the back surface, and the second connecting member 420 comprises an arc-shaped body 421 having a circular cross-section smaller in diameter than the through hole 413 and an arc-shaped region extending in an arc shape, with the ends of the arc-shaped body 421 attached to one end of the tie rod 20 while passing through the through hole 413.

[0027] Furthermore, in this embodiment, the first connecting member 410 has an extended region 415 that extends from the wall 10 toward the ground wall surface 110 in a positional relationship with the through hole 413 in the direction of expansion of the wall 10, and this extended region 415 functions as a reinforcing member against bending of the plate-like body 411.
