Description

  The present invention relates to a boundary block, in particular, a boundary block that can be used for a flower bed and the like and a boundary structure using the boundary block.

  Conventionally, when forming a flower bed or a curbstone, after constructing a foundation work along the boundary line, it is constructed by stacking concrete blocks and bricks along the boundary line while fixing them with mortar. In addition, it has also been proposed to form flower beds, curbs, and the like by a dry method that does not use mortar, in contrast to a wet method that uses such mortar.

For example, as described in Patent Document 1, after a floor plate formed by standing a bolt on an iron plate is laid along a boundary line, a plurality of holes are inserted into the floor plate by inserting the vertical holes of the boundary block into the bolt of the floor plate. The boundary blocks are arranged in order, and the nuts are fastened to the bolts to fix the boundary blocks to the base plate. Next, the bolts are fastened to the nuts, and then the vertical bolts of the new boundary blocks are inserted into the extended bolts. A new boundary block is stacked in order on the boundary block previously arranged, and a new boundary block is fixed by fastening a nut to a bolt, and thereafter, the same operation is performed to form a boundary such as a flower bed. .

It is formed by joining together.

  FIG. 5 shows a boundary formed by the dry method using the boundary block 1 and the end boundary block 12 thus configured.

  Hereinafter, the construction procedure for forming the boundary shown in FIG. 5 will be described.

  First, a base plate 21 is prepared in which a plurality of bolts 23 are erected on the base plate 22 with a set interval (see FIG. 6). Here, the interval between the bolts 23 of the floor plate 21 is set to an integer multiple of the width dimension of the boundary block 1, for example, an interval twice, and the length thereof extends from the lower end surface of the boundary block 1 to the upper surface of the connecting portion 4. It is set so that the tip is located slightly beyond.

  Next, after excavating the boundary line and the ground in the vicinity thereof to a set depth, the crusher run 31 (see FIG. 5) is spread over a certain depth to level the ground. Next, a plurality of floor plates 21 are laid in order on the crusher run 31 along the boundary line via the sand cushion 32 (see FIG. 5). At this time, when the level of the floor plate 21 is required, a plastic level plate 24 (see FIG. 6) is disposed on the crusher run 31 to adjust the unevenness of the floor plate 21.

  Instead of the sand cushion 32, an empty kneaded mortar can be used.

  Thereafter, along the boundary line, the end boundary block 12 is arranged at the start end, for example, the right end. Then, the right end face is abutted against the left end face of the arranged end boundary block 1, and the boundary block 1 is sequentially arranged in the left direction along the boundary line. At this time, the boundary block 1 is arranged so that the bolts 23 of the floor plate 21 are positioned substantially at the center of the space formed by the concave portions 4a of the connecting portions 4 formed by abutting the left and right end surfaces of the adjacent boundary blocks 1. (See FIG. 7).

  If the boundary block 1 is arranged along the boundary line, the boundary block 1 has a width corresponding to the width of the guide groove 4 c formed on the upper surface of the connection portion 4 in the boundary block 1, according to the interval between the bolts 23 of the floor plate 21. A long connecting rail 25 in which mounting holes (not shown) are formed is arranged over the upper surfaces of the connection portions 4 of the plurality of boundary blocks 1. And the connection rail 25 was formed in the upper surface of the connection part 4 in the boundary block 1, inserting the attachment hole of the connection rail 25 in the volt | bolt 23 of the base plate 21 which protrudes from the upper surface of the connection part 4 in each boundary block 1. Arranged in the guide groove 4c. Next, the boundary block 1 is fixed to the floor plate 21 by fastening the nut 26 to the male screw of the bolt 23 protruding from the mounting hole of the connecting rail 25 (see FIG. 8).

  At this time, the guide block 4c formed on the upper surface of the connecting portion 4 in the boundary block 1 is placed along the linear connecting rail 25 so that the boundary block 1 is easily positioned and arranged along the boundary line. Can do.

  When the boundary block 1 is arranged and fixed along the boundary line, the end boundary block 12 is joined to the boundary block 1 via an adhesive at the end of the boundary line.

  When the fixing of the boundary block 1 and the end boundary block 12 is completed, the excavated earth and sand so as to cover the crusher run 31 is backfilled, and then the customer soil 33 is interposed between the front surface portion 2 and the back surface portion 3 of the boundary block 1. Fill. At this time, the customer soil 33 is rolled so that the customer soil 33 also enters the through hole 4b of the connecting portion 4. Then, planting may be performed on the filled soil 33 (see FIG. 9).

  As a result, the boundary block 1 can be arranged along the boundary line so that the boundary can be formed easily and in a short time, and planting can be performed just before the boundary line, without impairing the appearance. Moreover, since each boundary block 1 is fixed to the floor plate 21 by the connecting plate 25 fastened via the bolt 23 and the nut 26, the boundary can be maintained for a long time.

  In addition, when planting the boundary block 1 and providing a fence or the like, for example, as shown in FIG. 10, as shown in FIG. By using the plate 25, the pipe 27 can be arranged in a space having a set interval among the spaces formed by the concave portions 4 a of the connecting portions 4 in the pair of adjacent boundary blocks 1. Therefore, prior to filling of the land 33, a support 34 is inserted into each pipe 27 and fixed with a mortar, so that a fence or the like is provided using a plurality of supports 34 standing at set intervals. Is also possible.

  In the above-described embodiment, the case where the ground around the boundary line where the boundary block 1 is installed is excavated, and the crusher run 31 is spread and the floor plate 21 is laid is illustrated. For example, a flower bed is formed by dividing a sidewalk. For example, the boundary block 1 may be arranged by laying the floor plate 21 directly on a paved surface such as a sidewalk.

  Furthermore, in the above-described embodiment, the case where the boundary is formed by the dry construction method using the boundary block 1 along the linear boundary line has been described. However, the boundary block 1 is continuously formed over the entire circumference of a residential land or the like. You may arrange. Here, when the boundary line intersects at a set angle, the corner boundary block 11 may be used at the corner.

  Hereinafter, the case where a boundary is formed by the wet method using the boundary block 1, the corner boundary block 11, and the end boundary block 12 will be described with reference to FIGS.

  First, after excavating the boundary line and the ground in the vicinity thereof to a set depth, the crusher run 31 is spread over a certain depth, and then the foundation concrete 35 is placed on the crusher run 31 to construct the foundation work. At this time, the horizontal portion of the L-shaped anchor reinforcing bar 36 is embedded in the foundation concrete 35 at an interval of an integral multiple of the width dimension of the boundary block 1, for example, twice.

  After that, along the boundary line, the end boundary block 12 is disposed on the foundation concrete 35 via the height adjusting mortar 37 at the start end, for example, the right end. Then, the right end face is abutted against the left end face of the arranged end boundary block 12, and the boundary block 1 is sequentially arranged in the left direction along the boundary line. At this time, the boundary block 1 is arranged so that the vertical portion of the anchor reinforcing bar 36 is positioned substantially at the center of the space formed by the concave portion 4a of the connecting portion 4 formed by abutting the left and right end surfaces of the adjacent boundary block 1 To do.

  Here, when the boundary lines intersect at a set angle, the corner boundary block 11 may be used.

  When the boundary block 1 is arranged along the boundary line, the space by the concave portion 4a of the connecting portion 4 in the adjacent boundary block 1 is filled with the mortar 38, and the vertical portion of the anchor reinforcing bar 36 is embedded. At this time, the mortar 38 is filled so as to enter the through hole 4 b of the connection portion 4.

  In addition, when providing a fence etc. in the boundary block 1, the support | pillar 34 in the space where the anchor reinforcing bar 36 does not exist among the space formed of the recessed part 4a of the connection part 4 in a pair of adjacent boundary blocks 1 with a set space | interval. After that, the mortar 38 is filled and the support 34 is fixed.

  Further, in order to further increase the strength of the boundary block 1, the vertical portion of the anchor reinforcing bar 36 may be connected through a horizontal bar (not shown) prior to filling the mortar 38. As described above, when the anchor reinforcing bars 36 are connected to each other via the horizontal bars, the length of the vertical portion of the anchor reinforcing bars 36 protruding from the foundation concrete 35 is set from the lower end surface of the boundary block 1 to the upper surface of the connecting portion 4. It is preferable to set so that the tip is located slightly beyond. The mortar 38 is preferably filled so as to bury the upper end portion of the anchor reinforcing bar 36 projecting from the upper surface of the connection portion 2 and the upper surface of the connection portion 4 in each boundary block 1.

  Further, concrete can be used in place of the mortar 38.

  Next, after the earth and sand excavated so as to cover the height adjustment concrete 37 is backfilled, the soil 33 is filled between the front surface portion 2 and the back surface portion 3 of the boundary block 1, and then the filled soil soil 33 is filled. Just plant it.

  As a result, the boundary block 1 can be firmly installed while being accurately positioned along the boundary line, and planting can be performed up to the boundary line.

  Incidentally, FIG. 13 and FIG. 14 show the boundary block 5 of another embodiment.

  The boundary block 5 is formed with a height lower than that of the back surface portion 3 instead of the back surface portion 3 of the boundary block 1 described above, and its upper end surface is formed as a flat surface. Since it is not different from the boundary block 1 except that the back surface portion 6 in which the inclined surface is formed from the end edge to the back surface side edge of the upper surface of the connection portion 4, other detailed description is omitted.

  When the corner boundary block is formed by using the left end block 5L, the right end block 5R, and the intermediate block 5C formed of the boundary block 5 of this embodiment, the outer surface of the surface portion 2 is always positioned on the outer surface side. Therefore, the corner boundary block 13 (see FIG. 15) when the outer surface of the surface portion 2 of the left end block 5L and the outer surface of the surface portion 2 of the right end block 5R intersect at 270 degrees in the clockwise direction, and the left end block 5L. There are prepared two types of corner boundary blocks 14 (see FIG. 16) when the outer surface of the front surface portion 2 and the outer surface of the surface portion 2 of the right end block 5R intersect in the clockwise direction at 90 degrees.

  And also about the boundary block 5, the same code | symbol is attached | subjected to the member demonstrated previously, and as shown in FIG. 17, it can construct by a dry-type construction method and can form a boundary, It is the same as the member demonstrated previously. As shown in FIG. 18, the boundary can be formed by a wet method.

  When the boundary is formed using the boundary block 5, in addition to the space formed by the inner surface of the front surface 2 and the inner surface of the rear surface 6 of each boundary block 5, in the space defined by the outer surface of the rear surface 6 of the boundary block 5, The customer soil 33 can be filled beyond the height of the back surface portion 6. For this reason, the back surface part 6 of the boundary block 5 can be covered with the soil 33, the exposure of the boundary block 5 can be minimized, and the inner side of the boundary block 5 is also planted and greened. Can do. Therefore, for example, an island-like flower bed can be easily formed using the boundary block 5 on a sidewalk or the like.
