In the drawing, the wale and beotimbo structure 1 includes a plurality of wale 10 extending and disposed in contact with the retaining temporary structure 70. The wale 10 is composed of a wale body 110 and corner extensions 140 . The wales 10 are firmly coupled to each other even in a curved section by the corner extensions 140 . The wales 10 are coupled with the beotimbo 40 at the same time. The combination of the beotimbo 40 and the wale 10 is made by the length adjustment module 20.

On the other hand, beotimbo 40 is supported by being connected to the supporting beam 50 and the post pile 60. The supporting beam 50 is connected to the lower part of the beotimbo 40. The post pile 60 is connected to the side of the beotimbo 40. At the same time, the post pile 60 is also connected to the supporting beam 50. Therefore, the entire structure is firmly supported by contacting these three components and being coupled in the X, Y, and Z directions.

3 and 4 show an example of combining an oblique section in which the struts 40 are coupled to wales 10 forming an angle. In the drawing, two wales 10 form an angle with each other and are coupled by corner extensions 140. In this embodiment, the angle is close to 90 °, but the corner extension 140 of the present invention can combine the wales 10 without being limited to a specific angle, as will be described later.

Both ends of the beotimbo 40 are coupled to each of the wales 10 formed at an angle to each other and combined. In the drawing, one end of the strut 40 is coupled to the length adjustment module 20 and the pivot connector 30 in turn, and only the pivot connector 30 is coupled to the other end. According to this configuration, the wale 10 is firmly supported by the beotimbo 40.

The reinforcing plate 270 is movably installed between the end plate 220 and the second coupling plate 260, the central rod member 280 and the plurality of outer rod members 290 penetrate, and the end plate ( After setting the position for 220), it is possible to fix the plurality of outer rod members 290.

At this time, the reinforcing plate 270 has a plurality of through holes 271 formed at corresponding positions so that the central rod member 280 and the plurality of outer rod members 290 can pass through, and the central rod member 280 and the plurality of It is possible to prevent buckling of the central rod member 280 and the plurality of outer rod members 290 by coupling with the outer rod member 290.

The outer rod member 290 may be screwed to a nut member 291 installed on at least one of upper and lower surfaces of the reinforcing plate 270 and fixed to the reinforcing plate 270 .

On the other hand, the rotation connector 30 adjusts the coupling angle of the length adjustment module 20. 21 and 22, the rotation connector 30 includes a rotating shaft portion 31 and a coupling plate 36 coupled to the length adjustment module, and may be connected to the length adjustment module 20 or the wale body 40. .

In the above, preferred embodiments that can be implemented by the present invention have been described, but these are exemplary. The scope of the present invention should not be construed as being limited to the above embodiments, and it will be said that all the technical ideas of the present invention described above and the technical ideas underlying them are all included in the scope of the present invention.
