First time we are onsite since construction started last month. Foundation has been laid and now the walls are growing from the ground up. There are 12 people onsite, with 4 cement trucks doing the rounds the whole afternoon.
Out of the earthquake disaster in Tainan last February, we now know about the 135 degree bend that is needed for the pillars.
繫筋與耐震彎鉤
主筋之間必須綁紮足夠的繫筋，以加固核心混凝土的圍束效果。『繫筋』指橫向連結兩端主筋用的鋼筋，其一端需彎曲135ْْ，另一端為90ْ，形成耐震彎鉤。耐震彎鉤因伸入核心混凝土中，因此不易鬆脫。
