What ブロック積み do

An English description is being prepared. Japanese description:

建築用コンクリートブロックをモルタルや鉄筋を使って積み上げ、壁や塀(へい)・建物などを造る。
 建築用コンクリートブロックは、空洞ブロック、型枠状ブロック、化粧ブロックなどに分けられる。
 ブロック工事は、建築工事の中では大きな道具を使わない方である。作業場所の移動もあるが、取り扱う材料も比較的小型なので小回りがきく。
 作業はまず、必要な量の建築用コンクリートブロック、砂、セメント、鉄筋などを所定の場所まで運ぶ。次に、ブロック積上げの所定の位置を明示する線(墨)を確認し、基礎を造り、ブロック用の遣り方を堅固に建て、水糸を張る。セメントと砂(1:2.5~3)を水で適当な硬さに練り合わせてモルタルをつくり、鏝(こて)や鏝板などを使ってコンクリートの基礎に塗り、高さの調整などを行う。鉄筋を配したコンクリート基礎の上に、順次モルタルで調整、空洞部へモルタルを充填(てん)し、計画通りの段数ごとに横鉄筋を配しながら、最下段から一段ずつ積む。積み上げにあたっては、あらかじめ決められた割付け(遣り方)に従い、糸の先に逆円錐形のおもりを垂らした水糸(下げ振り)を張り、ブロック端部(たんぶ)が垂直になるよう順次、上方に積み上げて行く。
 ブロック積みが終わるとモルタルのほど良い硬化を待ち、刷毛(はけ)などを使って、ブロックを水洗いし汚れを落として、目地(めじ)部モルタルを仕上げる。仕上げには、ブロックの仕上げそのものを見せる「化粧積み」と、ブロックの上にモルタル塗りやタイル張りなどを施す「下地積み」があり、前者の場合には目地をモルタルで美しく仕上げる「目地ごしらえ」という工程が加わる。

How AI is changing this job

A written analysis for this occupation is being prepared.

AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
