Meanwhile, although not shown, a method of processing logs according to an embodiment of the present invention includes the steps of inserting a stainless steel bar into each of a plurality of holes 50 formed in a wood, injecting a polymer And may further include a corrosion preventing portion for preventing the corrosion of the wood and improving the strength of the wood. In other words, the corrosion prevention part inserts a stainless steel bar into the inner hole of the dried wood, or injects the polymer.

Hereinafter, a method for processing logs according to an embodiment of the present invention will be described in detail with reference to FIG.

Referring to FIG. 4, a method for processing logs according to an embodiment of the present invention includes: (S110) supplying high-temperature, high-pressure steam to wood; Applying pressure to the curved portion of the wood (S120); Forming a plurality of holes in the wood (S130); Drying the wood (S140); And blocking the holes formed in the wood to prevent corrosion and improve the strength of the wood (S150).

Meanwhile, in one embodiment of the present invention, the wood may be wood, but is not limited thereto.

In step S110 of supplying steam to the wood at a high temperature and a high pressure, steam can be supplied to the wood for 4 to 5 days in a high-temperature and high-pressure environment to soften the wood of the wood. At this time, the atmospheric pressure may be, for example, 20 to 30 atm, and the temperature may be 200 to 300 ° C, but is not limited thereto.

In step S120, following the above steps, the structure of the wood is made very flexible and then the pressure is applied to the bent part of the wood, the bent part of the wood is pressed while rotating the wood.

In the log processing method according to an embodiment of the present invention, the log is slowly pressed while rotating the log until the bent part of the log straightens. At this time, the operation of flattening the bent part of the log can be repeatedly performed.

Subsequently, in step S130 of forming a plurality of holes in the wood, a plurality of holes are formed in the longitudinal direction of the log, that is, in the horizontal direction.

At this time, each of the plurality of holes may be formed at one end face of the wood and at the other end face of the wood. More specifically, among the plurality of holes, the first hole may be a first groove formed from one end face of the wood and a second groove formed from the other end face of the wood. In other words, one half of the first hole can be formed in one direction of the cross section of the wood, and the other half can be formed in the direction of the other cross section of the wood.

Next, in the step of drying the wood (S140), the wood is vertically raised so as to allow air to flow through each of the plurality of holes formed in step S130, and the wood is dried by natural convection of air.
