方形柱頭構(gou)造設(she)計：突緣支承(cheng)加勁(jing)板(ban)(ban)的底部應刨平并應在(zai)軸線附(fu)近與柱頂(ding)(ding)板(ban)(ban)頂(ding)(ding)緊(jin)。為提高柱頂(ding)(ding)的抗(kang)彎剛度，應加設(she)一(yi)塊墊板(ban)(ban)，并在(zai)軸線處增(zeng)設(she)加勁(jing)肋。兩梁間(jian)應留(liu)10mm的空隙，安裝時尚應嵌入填板(ban)(ban)并用構(gou)造螺栓固(gu)定。對于格構(gou)式(shi)柱，為了保證傳(chuan)力均(jun)勻，在(zai)柱頂(ding)(ding)應設(she)置綴板(ban)(ban)把兩肢連接起來，分肢之間(jian)頂(ding)(ding)板(ban)(ban)下面應設(she)置加勁(jing)肋。
