Description

TECHNICAL FIELD The present invention relates to a wooden windbreak fence that does not use metal binding tools, is entirely made of wooden logs, and does not pollute the environment even if it rots over time.

As shown in the front view of FIG. 9 and the cross-sectional view of FIG. It is crossed and tied with binding iron wire and fixed.
Logs of the same standard are assembled on site and arranged in a simple assembly, so it is easy to assemble, dismantle, and move, and has high stability against wind. There are effects such as being able to freely change the height of the windbreak fence.

However, this construction method is a construction method considering the promotion of vegetation for the purpose of disaster prevention and windbreak in the coastal area, but due to salt damage in the coastal area, the protective body collapses quickly due to the corrosion of the binding iron wire and metal, and the purpose is short-lived. It can be seen that In addition, scattering of the dropped metals is dangerous and costs labor costs for recovering the metals. Therefore, the development of a wooden windbreak fence that does not use binding iron wires and metals has been desired.

In addition, the applicant of the present application has developed a wooden protective body that uses wood such as thinned wood, is assembled with a simple joint structure, has a low processing cost, and is friendly to environmental conservation (see Patent Document 1). .

An embodiment of the wooden windbreak fence of the present invention will be described below with reference to the accompanying drawings.
As shown in the front view of FIG. 1 and the right side view of FIG. 2, the wooden windbreak fence of the present invention comprises an upper horizontal tie log 1 and a lower horizontal tie log 2 arranged vertically in parallel with a predetermined interval, and Notched semicircular recesses 6 to be fitted to the upper log 1 and the lower log 2 are provided on the outer peripheral surface, and are fitted to the left and right ends of the upper log 1 and the lower log 2. The first vertical log 3 at the end and a notched semicircular concave portion 6 fitted to the upper log 1 and the lower log 2 are provided on the outer peripheral surface, and are adjacent to the inner side of the first vertical log 3 at the end. The second vertical log 4 at the end and the cuts that are arranged continuously adjacent to the inside of the second vertical log 4 at the end and alternately fit the upper log 1 and the lower log 2 at the horizontal connection. A main vertical log 5 having a notched semicircular recess 6 on its outer peripheral surface and arranged in a triangular structure by fitting the semicircular recesses 6 alternately to the horizontal connecting upper log 1 and the horizontal connecting lower log 2 in an intersecting manner. Consists of

The horizontal connecting upper log 1 and the horizontal connecting lower log 2 are made of cylindrical bodies with the same diameter that are machined to the same standard, are arranged vertically in parallel with a predetermined interval, and are natural or natural to suit drug injection. It is best to use Akita cedar that has been kiln-dried.

As shown in the front view of FIG. 3(a), the first vertical log 3 at the end has a notch semicircular concave portion 6 fitted to the upper horizontal connecting log 1 and the lower horizontal connecting log 2 on the outer peripheral surface. In preparation for vertically symmetrical positions, as shown in the bottom view of FIG.
Further, as shown in (a) the front view, a wooden plug hole 8 for inserting a wooden plug 7 is formed through the notched semicircular concave portion 6 at the central position of the vertically symmetrical position. The wooden plug holes 8 are preferably made of the wooden plugs 7 made of cedar square lumber.

As shown in the front view of FIG. 4(a), the second vertical log 4 at the end has a notch semicircular concave portion 6 fitted to the upper horizontal connecting log 1 and the lower horizontal connecting log 2 at the end. They are provided at vertically symmetrical positions on the outer peripheral surface on the side opposite to the first vertical log 3 .
Also, similarly to the first vertical log 3 at the end portion, as shown in (a) front view, a wooden plug hole 8 for inserting a wooden plug 7 is inserted into the central position of the notched semicircular concave portion 6 at a vertically symmetrical position. to form through. The wooden plug holes 8 are preferably made of the wooden plugs 7 made of cedar square lumber.

As shown in the front view of FIG. 5(a), the main vertical log 5 has notched semicircular recesses 6 fitted to the horizontal connecting upper log 1 and the horizontal connecting lower log 2 at vertically symmetrical positions on the outer peripheral surface. prepared for.
