  The boundary block 1 of this embodiment has a wooden block body 3 formed by stacking a plurality of wooden plate members 2 in the vertical direction, and an anchor bolt penetrating from the vicinity of the upper part to the lower surface 3a inside the wooden block body 3. An insertion hole 4 is provided, and an anchor bolt 6 erected and fixed in advance to the foundation 5 is inserted into the anchor bolt insertion hole 4 and an upper portion of the anchor bolt 6 is fixed with a nut 7 to fix the wooden block body to the foundation 5. 3 is a boundary block, and a spacer 8 is partially disposed between the lower surface 3a of the wooden block body 3 and the upper surface 5a of the foundation 5, so that the lower surface 3a of the wooden block body 3 and the foundation 5 are It is a boundary block characterized by being separated from the upper surface 5a. Hereinafter, each configuration will be described in detail.

  As shown in FIG. 1 or FIG. 2, the wooden block body 3 is formed by overlapping a plurality of wooden plate members 2a, 2b, 2c, and an anchor bolt insertion hole penetrating from the vicinity of the upper portion to the lower surface 3a. 4 and a nut fixing space 9 provided near the upper portion.

  Specifically, the wooden board 2 of this embodiment includes a first wooden board 2a arranged at the uppermost part, a second wooden board 2b arranged at the lowermost part, and three stages adjacent to the central part. It consists of three 3rd wooden board | plate materials 2c arrange | positioned over. These are sequentially stacked (stacked) in the vertical direction to form one wooden block body 3 as a whole.

  The first wooden board 2a is formed to have a thickness of 45 mm, a width of 200 mm, and a length of 1800 mm. The upper and left and right sides are chamfered, and the upper surface is formed as an inclined surface. Since the upper surface of the wooden block body 3 becomes an inclined surface, rainwater or the like flows down without accumulating on the upper surface, so that damage to the wooden block body 3 is further suppressed. In addition, although the upper surface of this Example is each formed in the downward inclined surface toward the both sides from the center vicinity, you may form in the inclined surface which goes to one side.

  The second wooden board 2b is formed in a size of thickness 50 mm × width 200 mm × length 1800 mm, and the third wooden board 2c is formed in a size of thickness 35 mm × width 100 mm × length 1800 mm. Has been.

  Although the boundary block of this embodiment is made of a total of five wooden boards, it may be any number as long as it is plural, and the dimensions of each wooden board can be changed as appropriate. All the wooden plates may have the same dimensions.

  As described above, since the boundary block of the present invention is formed of a plurality of wooden boards, it is possible to use inexpensive small-diameter wood and laminated timber, and it can be partially replaced even if part of it is damaged. Therefore, the cost required for production and repair can be reduced. In particular, as in this embodiment, if a board having a small width is used as the wooden board disposed in the middle part and wide boards are disposed above and below the wooden board, a cheaper small-diameter tree can be utilized in the middle part.

  As wooden boards, coniferous trees such as pine, oak, birch, and cedar can be suitably used, but especially after the war, a large amount of trees are planted as components of utility poles. By doing so, it is possible to effectively use wood resources.

  Inside the wooden block body 3, an anchor bolt insertion hole 4 penetrating from the vicinity of the upper portion to the lower surface 3a is drilled. The anchor bolt insertion hole 4 is a part through which the anchor bolt 6 is inserted when the boundary block 1 is disposed, and is provided to extend in the vertical direction near the center of the wooden block body 3.

  As shown in FIG. 1, the boundary block 1 of this embodiment is one in which the anchor bolts 6 are inserted and disposed near both ends in the longitudinal direction, and the anchor bolt insertion holes 4 are also provided corresponding thereto. Two locations are formed near both ends in the longitudinal direction. However, the formation site of the anchor bolt insertion hole 4 is not limited to this, and the design can be appropriately changed according to the number and location of the anchor bolts erected on the foundation 5.

  A nut fixing space 9 is provided in the upper part of the wooden block body 3. The nut fixing space 9 is a space for fixing the upper portion of the anchor bolt 6 with the nut 7 when the boundary block 1 is disposed.

  As shown in FIG. 1 or 2, a spacer 8 is partially arranged between the lower surface 3 a of the wooden block body 3 and the upper surface 5 a of the foundation 5, and the lower surface 3 a of the wooden block body 3 It is comprised so that the upper surface 5a of the foundation 5 may space apart. This is because the boundary block 1 is most likely to corrode with water and bacteria on the boundary surface between the wooden block body 3 and the foundation 5, and the spacer 8 is disposed at this site, so that the wooden block body 3 This is because the lower surface 3a is levitated from the upper surface 5a of the foundation 5 to maintain the dry state of the lower surface 3a of the wooden block body 3 and prevent corrosion.

  Specifically, a brass cage is used for the spacer 8 of this embodiment, and this brass cage has a strength that does not crush even in a small space due to the weight of the wooden block body 3 and is more suitable without rusting. is there. In addition, as shown in FIG. 1 or FIG. 3, nine spacers in this embodiment are provided on each side and near the center in the longitudinal direction of the wooden block body 3 in total. Is placed on the lower surface or the bottom surface 3a of the wooden block body 3 by being punctured on the lower surface of the wooden plate member 2b, and the head of the brass cage 8 is formed between the lower surface 3a of the wooden block body 3 and the upper surface 5a of the foundation 5. The separated state is maintained.

It may be anything. Further, the distance between the lower surface 3a of the wooden block body 3 and the upper surface 5a of the foundation 5 is preferably about 3 to 5 mm as long as the ventilation between them can be secured.

  Further, as shown in FIG. 4, a water draining groove 11 is provided on the upper surface 5 a of the foundation 5 of this embodiment from the standing part of the anchor bolt 6 to the end part. This is because the mortar 10 is filled in the nut fixing space 9, but the mortar 10 contracts due to changes over time and moisture flows into the nut fixing space 9, and accumulates in the anchor bolt insertion holes 4 to cause corrosion. This is because it causes the water flowing through the anchor bolt 6 to be discharged to the outside through the water draining groove 11.

  Specifically, the draining groove groove 11 of this embodiment is formed in a V shape from the standing part of the anchor bolt 6 toward both ends, so that both ends are positioned on the low ground side. It is formed. For example, when the boundary block 1 is disposed on a completely flat ground, the water draining groove 11 is provided in a direction perpendicular to the longitudinal direction from the standing portion of the anchor bolt 6 and as it goes to both ends. You may form so that a groove | channel may become deep.

Next, a method for disposing (attaching) the boundary block 1 according to the present invention will be described.
Boundary block 1 is the boundary between the sidewalk or median strip on the road and the roadway, the boundary between the parking lot and the approaching roadway in various facilities (hospital, park, rotary in front of the station, high-speed service area, etc.), or in various facilities In order to divide the flower bed etc., it is arranged at a necessary part as appropriate.

  At the time of arrangement, first, as a foundation formation, a crushed stone layer (not shown) is formed, and then concrete is placed thereon to form a foundation 5 as shown in FIG. When placing concrete, the anchor bolt 6 is erected and fixed, and a water draining groove 11 is formed on the upper surface 5a of the foundation 5 from the erected portion of the anchor bolt 6 to the end.

  After the concrete is hardened and the foundation 5 is formed, the wooden block body 3 is placed on the upper part of the foundation 5. This placement is performed such that the anchor bolt 6 is inserted into the anchor bolt insertion hole 4.

  The wooden block body 3 includes a step of forming a plurality of wooden plate members 2 to a required size, a step of superposing a plurality of wooden plate members 2 to form a block body, and forming anchor bolt insertion holes 4 inside the block body. It is manufactured through a process of preserving the wooden board 2, a process of treating the surface of the block body, and a process of arranging the spacer 8 on the lower surface of the wooden block body 3.

  Then, after placing the wooden block body 3 on the upper part of the foundation 5, the nut 7 is screwed into a screwing part provided on the upper part of the anchor bolt 6, and is firmly fixed via a washer. In this state, the nut fixing space 9 is filled with the mortar 10 and cured to complete the arrangement.

  Further, another embodiment of the boundary block of the present invention shown in FIG. 5 will be described. The difference between the boundary block 20 of this embodiment and the boundary block 1 described above is that the boundary block 20 is a boundary block in which earth and sand are arranged on one side of the wooden block body 3 (for example, a boundary block for flower bed configuration or a mound-up sidewalk) This is the same as the boundary block for construction) except that a resin sheet 21 is attached to one side of the wooden block 3. The same components as those of the boundary block 1 are denoted by the same reference numerals and description thereof is omitted.

  Specifically, the flower bed constituting boundary block or the mound-up sidewalk constituting boundary block is usually easily corroded because one side of the wooden block body 3 is in contact with earth and sand. For this reason, for example, the olefin resin sheet 21 is attached to one side surface of the wooden block body 3 of the boundary block 20 of this embodiment with an adhesive so that the one side surface of the wooden block body 3 does not come into contact with earth and sand. It is configured.

  As described above, the boundary block of the present invention realizes a wooden boundary block that can be used for a longer period of time by adopting many structures in which the wooden block body does not corrode more.

It is a side view of the boundary block of this invention. It is an AA line expanded sectional view of FIG. It is a BB line expanded sectional view of Drawing 1.
