style="text-indent:25px">疊合梁簡述：采用疊合式構(gòu)件，可以減輕裝配構(gòu)件的重量更便于吊裝，同時由于有后澆混凝土的存在，其結(jié)構(gòu)的整體性也相對較好。其薄弱環(huán)節(jié)主要在預(yù)制構(gòu)件與后澆混凝土兩者之間的結(jié)合面上?？蚣芰旱臋M截面一般為矩形或T型，當(dāng)樓蓋結(jié)構(gòu)為預(yù)制板裝配式樓蓋時，為減少結(jié)構(gòu)所占的高度，增加建筑凈空，框架梁截面常為十字形或花籃形，在裝配整體式框架結(jié)構(gòu)中，常將預(yù)制梁做成T形截面，在預(yù)制板安裝就位后，再現(xiàn)澆部分混凝土，即形成所謂的疊合梁。</p></p><br
