智能玻璃大(da)棚(peng):Venlo型玻璃溫(wen)室(shi) 一(yi)種(zhong)多屋(wu)(wu)(wu)(wu)脊(ji)(ji)連棟小(xiao)屋(wu)(wu)(wu)(wu)面(mian)玻璃溫(wen)室(shi),溫(wen)室(shi)單間(jian)跨(kua)度(du)為6.4m、8m、9.6m、12.8m,開(kai)間(jian)距為3m、4m或4.5m,檐高(gao)3.5~5.0m,每(mei)跨(kua)由兩個(ge)(ge)或三個(ge)(ge)(雙(shuang)屋(wu)(wu)(wu)(wu)面(mian)的)小(xiao)屋(wu)(wu)(wu)(wu)面(mian)直接支承(cheng)在桁架上(shang),小(xiao)屋(wu)(wu)(wu)(wu)面(mian)跨(kua)度(du)為3.3m,矢高(gao)0.8m。近年有改良為4.0m跨(kua)度(du)的。根(gen)據桁架的支承(cheng)能力,還可將兩個(ge)(ge)以上(shang)的3.2m的小(xiao)屋(wu)(wu)(wu)(wu)面(mian)組合成6.4m、9.6m、12.8m的多脊(ji)(ji)連棟型大(da)跨(kua)度(du)溫(wen)室(shi)。可大(da)量免去早期每(mei)小(xiao)跨(kua)排(pai)水槽下(xia)的立柱,減(jian)(jian)少(shao)(shao)構件遮光(guang),并使溫(wen)室(shi)用(yong)鋼量從普通溫(wen)室(shi)的12~15kg/㎡減(jian)(jian)少(shao)(shao)到5kg/㎡,其覆蓋材(cai)料采用(yong)4mm厚(hou)的園(yuan)藝(yi)專用(yong)玻璃。由于(yu)屋(wu)(wu)(wu)(wu)面(mian)玻璃安裝從排(pai)水溝(gou)直通屋(wu)(wu)(wu)(wu)脊(ji)(ji),中間(jian)不加(jia)檁條,減(jian)(jian)少(shao)(shao)了屋(wu)(wu)(wu)(wu)面(mian)承(cheng)重構件的遮光(guang),且排(pai)水溝(gou)在滿足排(pai)水和結構承(cheng)重條件下(xia),減(jian)(jian)少(shao)(shao)了排(pai)水溝(gou)的截(jie)面(mian)(溝(gou)寬從0.22m縮小(xiao)到0.17m),提高(gao)了透光(guang)性(xing)。開(kai)窗(chuang)(chuang)(chuang)設置以屋(wu)(wu)(wu)(wu)脊(ji)(ji)為分界線,左右交錯(cuo)開(kai)窗(chuang)(chuang)(chuang),每(mei)窗(chuang)(chuang)(chuang)長1.5m,一(yi)個(ge)(ge)開(kai)間(jian)(4m)設兩扇窗(chuang)(chuang)(chuang),中間(jian)1m不設窗(chuang)(chuang)(chuang),并在頂側(ce)通風(feng)、外遮陽,濕簾-風(feng)機降(jiang)溫(wen),加(jia)固基礎強(qiang)度(du),加(jia)大(da)排(pai)水溝(gou),增加(jia)夏季(ji)通風(feng)降(jiang)溫(wen)效(xiao)果。
