Description

  The present invention relates to a civil or architectural block used for a standing structure such as a fence, a safety fence, and a retaining wall, and particularly relates to a block having a self-supporting performance.

  Conventionally, concrete blocks for civil engineering or construction have been produced at factories and assembled at construction sites. Such a block is formed in the shape of a rectangular parallelepiped in consideration of the ease of manufacture and the efficiency of the storage space during storage and transportation.

  In addition, in the conventional block, the strut penetration holes for penetrating the struts such as reinforcing bars have the same shape and the same size over the entire length, and the struts are penetrated into the strut penetration holes to form the strut penetration holes. Filled with concrete and hardened.

  However, since the above-mentioned conventional block is not self-supporting, there is a possibility that the block may fall down during storage, transportation, and construction, and therefore, it is necessary to devise measures that prevent the block from falling down. In addition, even if such a device is used, the block may fall over, and it is not easy to return to the standing state because it is heavy, and damage to the object or personal injury may occur. .

  In addition, when a pillar is penetrated into a pillar penetration hole of a conventional block and concrete is filled into the pillar penetration hole and solidified, it has the same shape over the whole length and the same shape over the whole length in the same size cavity. Since the same size shaft-shaped concrete part is in a state of being fitted, the fixing property is not so high.

  In view of the above problems with the conventional block, the present inventor has developed a block having improved self-supporting property and improved adhesion as a result of extensive research.

  The self-supporting block according to the present invention includes a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion, and the base portion is one of a front side and a back side of the vertical wall portion at a lower portion of the vertical wall portion. Alternatively, both are provided so as to project in the horizontal direction.

  By comprising in this way, since a vertical wall part is supported by a base part, the independence of a block improves and it becomes difficult to fall down.

  In addition to the above configuration, a height adjusting member may be disposed on the vertical wall portion and the base portion.

  With this configuration, even when the block is tilted when the block is erected, this can be corrected.

  Furthermore, in addition to the above-described configuration, a structure may be provided that includes a column penetrating hole that penetrates in the vertical direction inside the vertical wall portion.

  If comprised in this way, when assembling a block, a block penetration hole can be fitted in the said support | pillar, and a block can be installed.

  In addition, when the through hole for the column is configured so that the cross-sectional area increases from the lower part to the upper part, the cross-sectional area of the shaft-shaped concrete portion that is filled and solidified in the through hole for the column increases from the lower part to the upper part.

  Furthermore, when the concrete filling hole is provided in the base portion, the concrete filled from the concrete filling hole enters below the base portion.

  The self-supporting block according to the present invention includes a vertical wall portion and a base portion provided at a lower portion of the vertical wall portion, and the base portion is one of a front side and a back side of the vertical wall portion at a lower portion of the vertical wall portion. Alternatively, since the vertical wall portion is supported by the base portion so that the vertical wall portion is supported on both sides, the self-supporting property of the block is improved and it is difficult to fall down. The trouble of returning to the state, the damage of things and the risk of personal injury are eliminated.

  In addition to the above configuration, when the height adjustment member is arranged on the vertical wall portion and the base portion, the installation location may not be horizontal or uneven when the block is erected. Thus, even if the block is inclined, it can be corrected, so that the block can always stand upright.

  Moreover, if the through-hole for the column is configured so that the cross-sectional area increases from the lower part to the upper part, the cross-sectional area of the shaft-shaped concrete portion that fills and solidifies in the through-hole for the column increases from the lower part to the upper part. The shape has an advantage that the adhesion between the block and the shaft-like concrete portion is improved.

  Furthermore, when a concrete filling hole is provided in the base portion, when the block is installed and the block is solidified with concrete, when the concrete is filled from the concrete filling hole, the concrete enters below the base portion. Therefore, there is an advantage that a complete foundation can be solidified without any gaps.
