Description

  The present invention relates to protection technologies such as windbreak fences and fences using wood such as thinned wood, and reinforcements used for greening of road slopes and mountain slopes.

Conventionally, guard fences have a structure in which horizontal logs are placed on piles that have been processed into rolling logs, and vertical plates are driven by nails at required intervals, and horizontal members that are connected horizontally between adjacent struts. Although it was a structure (refer to patent documents 1) which arranged a plurality of windbreak fence wood for a frame and a support, the situation where the flying sand invades from the gap of the vertical interval and has influenced the planting growth of the back It is in. According to the research data of the Forestry Research Institute, a movement survey was conducted in the Tottori Sand Dunes, and it was found that the movement from the GL to about 6 cm was intense. In consideration of the current situation, a conventional vertical plate material is replaced with a horizontal plate, and a construction in which the horizontal plate is buried in 10 cm sand is considered.
Moreover, although the wooden guard fence which arrange | positioned the wooden beam over several steps between several wooden support | pillars is disclosed by Unexamined-Japanese-Patent No. 2014-25218 (refer patent document 2), Is joined via a metal joint, and even if both of them are decayed due to aging, the metal joint does not change to soil, and therefore it is not environmentally friendly and the processing cost is also joined. Due to the increased cost, windbreak fences for home use, windbreak fences for tree planting in sand dunes, and other techniques that cannot be used for streaks in slope greening methods.
Conventional woodworking techniques such as joining two members by joining a dowel and a dowel hole or joining a dowel and a dowel hole have been adopted for buildings and furniture, but it takes time to drill the hole. There is a problem that the arrangement posture of both holes is limited.
