鋼材的特點(diǎn)是強(qiáng)度高、自重輕、整體剛度好、變形能力強(qiáng)，故用于建造大跨度和超高、超重型的建筑物特別適宜；材料勻質(zhì)性和各向同性好，屬理想彈性體，符合一般工程力學(xué)的基本假定；材料塑性、韌性好，可有較大變形，能很好地承受動(dòng)力荷載；建筑工期短；其工業(yè)化程度高，可進(jìn)行機(jī)械化程度高的專(zhuān)業(yè)化生產(chǎn)。 </p> <p> 鋼結(jié)構(gòu)應(yīng)研究高強(qiáng)度鋼材，**提高其屈服點(diǎn)強(qiáng)度；此外要軋制新品種的型鋼，例如H型鋼（又稱(chēng)寬翼緣型鋼）和T形鋼以及壓型鋼板等以適應(yīng)大跨度結(jié)構(gòu)和超高層建筑的需要。 </p> <p>

鋼架大棚是現(xiàn)在農(nóng)業(yè)發(fā)展中不可或缺的重要溫室大棚，溫室大棚一般全部采用全鋼架大棚結(jié)構(gòu)，結(jié)構(gòu)先進(jìn)，抗風(fēng)雪能力強(qiáng)，適宜國(guó)內(nèi)大部分地區(qū)使用。這種鋼架溫室大棚骨架全部使用國(guó)標(biāo)熱鍍鋅鋼架加工而成，使用壽命更長(zhǎng)。雖然鋼架大棚先天有很多優(yōu)點(diǎn)，但是離不開(kāi)我們后期的維護(hù)，下面是一些具體的維護(hù)知識(shí)： </p> <p> 維護(hù)知識(shí)（一） </p> <p> 1、在搭建時(shí)要安裝牢固鋼架大棚 </p> <p> （1）棚腳入土到位棚腳邊緣的土壤，一般會(huì)因耕作逐年下降，使棚腳入土變淺，造成大棚傾斜。因此，大棚腳的入土深度一定要達(dá)到40厘米的標(biāo)準(zhǔn)。 </p> <p> （2）連接桿扎緊扎牢大棚的三道連接桿與骨架接觸部位用鐵絲扎緊扎牢，有的用竹竿做連接桿，但竹竿會(huì)因干燥收縮而松動(dòng)，因此，應(yīng)經(jīng)常檢查，隨時(shí)扎緊并間隔2—3年更換一次，以防竹竿老化，大棚傾斜。 </p> <p> （3）大棚支撐牢固水泥大棚兩端的混凝土支撐桿，用兩長(zhǎng)兩短，即兩根短撐桿與連接桿對(duì)準(zhǔn)。 </p> <p> <br /> 大棚高跨比大時(shí)，大風(fēng)不易損壞塑料薄膜。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="大理餐廳大棚工程,大棚"

正確的方法是，棚前臉處挖一條東西走向與大棚同長(zhǎng)的排水溝，排水溝寬約半米，深約30厘米左右。好讓大棚面上留下的水隨時(shí)流走，防止水流入棚內(nèi)。 </p> <p> 2、后兩排立柱間距太大 </p> <p> 溫室大棚內(nèi)后兩排立柱之間，間隔盡量縮小，應(yīng)在80厘米左右，中間只建一條東西走向的水泥溝兼人行路即可。 </p> <p> 3、兩棚之間空地太少 </p> <p> 首先，冬季前面大棚對(duì)后面遮陰太大，使大棚的前半部分蔬菜生長(zhǎng)不利。其次，對(duì)排澇害處較大。會(huì)出現(xiàn)冬季下雪時(shí)，掃雪棚前堆不下的情況。所以?xún)膳镏g空地的正確距離以4－5米為宜，這樣既不互相遮陰，又可防風(fēng)。 </p> <p> 4、后坡缺少保護(hù)措施 </p> <p> 要在溫室大棚后坡包上一層塑料布，再在外面包上一層無(wú)紡布。每10米左右用鋼絲封一下，這樣可保證五年左右，沒(méi)有太大的問(wèn)題。南方地區(qū)溫度較高，此地溫帶不明顯，故大棚的跨度可小一些。德宏餐廳大棚報(bào)價(jià)</p><p style="text-indent:25px"> 大棚高跨比越大，建造成本提高.大理餐廳大棚工程</p><p
