鋁(lv)(lv)模板中心(xin)支撐(cheng)與(yu)框架銜(xian)接處的結構(gou)請(qing)求(qiu)鋁(lv)(lv)模板中心(xin)支撐(cheng)與(yu)鋼(gang)(gang)框架梁(liang)柱(zhu)銜(xian)接處應契合下列結構(gou)請(qing)求(qiu)鋁(lv)(lv)模板H形截面中心(xin)支撐(cheng)翼緣(yuan)與(yu)鋼(gang)(gang)柱(zhu)或(huo)(huo)(huo)鋼(gang)(gang)梁(liang)銜(xian)接處，應在鋼(gang)(gang)柱(zhu)或(huo)(huo)(huo)鋼(gang)(gang)梁(liang)上(shang)設(she)置(zhi)加勁肋。加勁助應按(an)接受中心(xin)支撐(cheng)翼緣(yuan)分擔的軸心(xin)力對鋼(gang)(gang)柱(zhu)或(huo)(huo)(huo)鋼(gang)(gang)梁(liang)的程度或(huo)(huo)(huo)豎向分力計算。

　　當(dang)H形截(jie)面(mian)(mian)支(zhi)(zhi)撐(cheng)翼(yi)緣與箱(xiang)形截(jie)面(mian)(mian)鋼柱銜(xian)接時(shi)，在鋁模(mo)板(ban)(ban)鋼柱壁板(ban)(ban)的相應位置(zhi)(zhi)應設置(zhi)(zhi)橫隔板(ban)(ban)，Η形截(jie)面(mian)(mian)支(zhi)(zhi)撐(cheng)翼(yi)緣端(duan)部與鋁模(mo)板(ban)(ban)框(kuang)架(jia)梁柱構(gou)件銜(xian)接處(chu)，宜設計成(cheng)圓弧形，當(dang)中心支(zhi)(zhi)撐(cheng)桿件為填(tian)板(ban)(ban)銜(xian)接的組合截(jie)面(mian)(mian)時(shi)可采用鋁模(mo)板(ban)(ban)節點(dian)板(ban)(ban)停止銜(xian)接。

　　節點(dian)(dian)(dian)(dian)板邊緣與(yu)(yu)(yu)中心(xin)支(zhi)(zhi)撐(cheng)軸線(xian)(xian)的(de)夾角不(bu)應小于30",且節點(dian)(dian)(dian)(dian)板的(de)假定(ding)約(yue)束(shu)點(dian)(dian)(dian)(dian)連(lian)線(xian)(xian)應與(yu)(yu)(yu)支(zhi)(zhi)撐(cheng)桿端(duan)平(ping)行(xing)，防止支(zhi)(zhi)撐(cheng)受扭，.為了保證(zheng)鋁(lv)模板支(zhi)(zhi)撐(cheng)兩端(duan)的(de)節點(dian)(dian)(dian)(dian)板不(bu)發作(zuo)出平(ping)面外失(shi)穩(wen)，在(zai)支(zhi)(zhi)撐(cheng)端(duan)部(bu)與(yu)(yu)(yu)節點(dian)(dian)(dian)(dian)板假定(ding)約(yue)束(shu)點(dian)(dian)(dian)(dian)連(lian)線(xian)(xian)之間(jian)應預留2倍節點(dian)(dian)(dian)(dian)板厚度的(de)間(jian)。

　　鋁(lv)模板(ban)在(zai)停(ting)止抗震鋁(lv)模板(ban)設計時，中心支撐的截(jie)面宜(yi)采(cai)(cai)用(yong)軋制(zhi)寬翼緣Η型(xing)鋼，不宜(yi)采(cai)(cai)用(yong)焊(han)(han)接(jie)(jie)組(zu)合日形截(jie)面，由于(yu)在(zai)重復荷載作用(yong)下中心支撐易于(yu)屈曲，常招致(zhi)組(zu)合截(jie)面呈現焊(han)(han)縫斷裂。當采(cai)(cai)用(yong)焊(han)(han)接(jie)(jie)Η形截(jie)面時，翼緣和腹板(ban)之間應采(cai)(cai)用(yong)坡口全熔(rong)透燁縫銜接(jie)(jie)。
