The cushioning member 8 comprises an L-shaped cushioning support 8a as a support material, and an elastic wooden buffer 8b mounted on the buffering support 8a. 8a is mounted in the mounting hole 12d of the flange plate 12c by a fixing bolt / nut 8c which is a mounting tool protruding from the rear surface of the flange 8a. The wedge mounting surface 8c of the buffer body 8b facing the load C is formed at a wedge receiving angle α that approaches the load C toward the lower part, so that the wedge member 8 is in surface contact. The wedge member 9 is also made of, for example, elastic wooden material.

Therefore, the securing column 11 is moved around the axis by 9
By rotating the sockets by 0 ° and mounting them in the socket holes 3 and 6, the position of each side plate 12a can be changed in four stages.

As shown in FIG. 6, socket holes 17 and 1 formed in a floor rail (floor member) 15 and a ceiling rail (ceiling member) 16 constituting the floor surface 2 and the ceiling surface 5, respectively.
Numerals 8 are arranged evenly along the row direction, and are formed and arranged in a staggered manner in a plan view displaced in the rail length direction with respect to the socket holes 17 and 18 of the adjacent rails 15 and 16. Thereby, with respect to the side surface of the load C orthogonal to the length direction of the rails 15 and 16, an appropriate socket is inserted from two of the socket holes 17 and 18 at the approach distance DS or the socket holes 17 and 18 at the separation distance DL. Holes 17, 18
Can be selected.

As shown in FIG. 7, the socket holes 27 and 28 of the floor rail 25 and the ceiling rail 26 may be alternately shifted in the rail width direction. With this configuration, conventionally, only the socket holes 3 and 6 that are arranged at equal intervals at the center position of the floor rail 4 and the ceiling rail 7 are available, but the arrangement of the socket holes 27 and 28 is changed to a rail. By alternately shifting in the length direction and the width direction, the side of the two loads C is separated from the load C by the binding posts 11.
Can be selected from two distances DS and DL.

In the above configuration, the load C is carried into the hold by a working device such as a forklift, and two side surfaces (one or none) may be applied to the already fixed securing columns 11. At a predetermined position. Then, the securing posts 1 are inserted into the socket holes 17 and 18 of the floor rail 15 and the ceiling rail 16 corresponding to the other two side surfaces.

Further, when the lashing support 11 is mounted in the socket holes 17 and 18, the eccentric distances a, b, c, and d are selected from the eccentric distances a, b, c, and d corresponding to the distance between the side surface of the load C and the flange surface 11 c. It is possible to set an appropriate interval at which the buffer member 8 and the wedge member 9 can function properly.

8 to 10 show another embodiment.
The same members as those in the previous embodiment are denoted by the same reference numerals, and description thereof will be omitted. The lashing support 20 has a lower support mounting portion 21 and an upper support mounting portion 22 projecting from a lower end and an upper end of the support main body 12, each having a square cross section, and having a center inclined from the support main body corner. Distances e, f,
g and h are provided at different eccentric positions, and the flange surface 12c is inclined with respect to the side surface of the load C by an inclination angle β =
It is twisted around the axis so as to incline in the range of 20 ° to 40 °. In addition, the buffer 23 of the buffer member 8 is
The wedge mounting surface 23c is formed at an inclination angle β such that the lower the wedge mounting surface 23c is, the closer to the load C side. Therefore, fine adjustment for enlarging or reducing the distance between the wedge mounting surface 23c and the side surface of the load C can be performed by the adjusting unit that slides the buffer body 23 left and right on the buffer receiver 8a. Of course, as in the previous embodiment, when the securing column 11 is mounted in the socket holes 17 and 18, the side faces of the load C are selected from the eccentric distances e, f, g, and h in the inclination directions at every 90 °. Can be selected according to the distance between the flange 11c and the flange surface 11c. Here, when the inclination angle β is less than 20 °, the change in the distance between the wedge mounting surface 23c and the side surface of the load C due to the slide of the buffer 23 is small. This is because the component force becomes large and the buffer 23 cannot be supported by the frictional force of each other on the buffer receiver 8a, and may slip.

In the above configuration, the load C is carried into the hold by a working device such as a forklift, and is placed at a predetermined position so that, for example, two sides are applied to the lashing posts 11 that are already erected. Then socket holes 1 of floor rail 15 and ceiling rail 16 corresponding to the other two sides
The lashing struts 11 are mounted on 7 and 18. At this time, first, the socket holes 17 and 18 at appropriate positions are selected, and further, the lashing support 11 is rotated about the axis corresponding to the distance between the side surface of the load C and the socket holes 17 and 18 so that every 90 ° From the eccentric distances e, f, g, and h in the inclination direction, the interval at which the buffer member 8 and the wedge member 9 can function more appropriately is selected. Then, the buffer receiver 8a is attached to a predetermined position of the column main body 21, and the buffer 23 is slid left and right on the buffer receiver 8a.
The distance between the wedge mounting surface 23c and the side surface of the load C is finely adjusted, and the wedge member 9 is driven between the wedge mounting surface 23c and the side surface of the load C from above, thereby firmly fixing the load C.

According to the above embodiment, in addition to the operation and effect of the above embodiment, the wedge mounting surface 23c and the side surface of the load C are formed by sliding the buffer 23 right and left on the buffer receiver 8a. Can be finely adjusted, and an optimum interval by the wedge member 9 can be set. In addition,
In the above-described embodiment, the inclination angle β is given to the column mounting portion 21 and the upper column mounting portion 22.
May be inclined at an inclination angle β.
