NEW BUILDING BLOCK FORM BLOCK, CONCRETE STRUCTURE AND CONSTRUCTION METHOD OF CONCRETE FOUNDATION
To provide a new building block form block which eliminates the necessity of fastening work on a lower end side at the time of bolt fastening, and which can perform constitution of a concrete structure in a short period, to provide a concrete structure, and to provide a construction method of concrete foundation.SOLUTION: In a new building block form block 2 for constituting a concrete structure 1 by being stacked in a plurality of stages and being fastened by a bolt, a bolt insertion hole 22 is communicated from an upper end surface 211 of a block body 21 to the front of a lower end part, and a cross-sectional shape in a plan view has longitudinal width larger than the length in the longer direction of a T-shaped end part 41 and also has lateral width smaller than the length in the longer direction of the T-shaped end part 41, corresponding to the dimension of the T-shaped end part 41 of a T-shaped bolt 4 which is inserted. A bolt locking chamber 23 includes a space in which the T-shaped bolt 4 is rotatable by about 90 degrees around a rotation axis, and has a ceiling surface 231 which brings an upper end surface 411 of the T-shaped end part 41 into contact and locks it.SELECTED DRAWING: Figure 2
【課題】 ボルト締結時の下端側の締結作業を不要にし、コンクリート構造物の構築を短期間に行うことのできる、新積木型枠ブロック、コンクリート構造物およびコンクリート基礎の施工方法を提供する。【解決手段】 複数段に積み重ねてボルトで締結することによりコンクリート構造物１を構築するための新積木型枠ブロック２であって、ボルト挿入孔２２は、ブロック体２１の上端面２１１から下端部手前まで連通されているとともに、平面視の断面形状が、挿入されるＴ字ボルト４のＴ字形端部４１の寸法に対応して、当該Ｔ字形端部４１の長手方向長さより大きな寸法の縦幅を有するとともに、Ｔ字形端部４１の長手方向長さより小さな寸法の横幅を有しており、ボルト係止室２３は、Ｔ字ボルト４を回転軸回りに約９０度回転可能な空間を備えているとともに、Ｔ字形端部４１の上端面４１１を当接させて係止する天井面２３１を有している。【選択図】 図２
