農(nóng)村的小叔子家里的房子是他自己蓋的，伊犁鍍鋅槽鋼哪家好，對建房子很有自己的一套方法。上次我特地請教他關于閣樓上用槽鋼還是用工字鋼的問題，他很是耐心的給我講解。首先一起了解一下什么是槽鋼和工字鋼。槽鋼和工字鋼是鋼筋結構隔層的兩種類型，還包括鋼結構現(xiàn)澆混凝土，基本上是這三種。一、槽鋼：1、優(yōu)點：它的搭建速度快，隨搭隨用，不需要等待很久。槽鋼一般用于小面積小跨度戶型，適合家用。槽鋼可以改變建筑物的著力結構，節(jié)省建筑用材。2、缺點：槽鋼做的閣樓當人在上面走動時，會有一定的晃動聲，槽鋼規(guī)格越小，晃動聲越大。槽鋼規(guī)格越大，晃動聲越小。二、工字鋼：1、優(yōu)點：工字鋼的很寬，側向剛度大，抗彎強度會更高，經(jīng)久耐用，一般用于大跨度大面積的樓房或者廠房。表面平行讓連接、加工、安裝更加簡便。殘余應力小，無需昂貴的焊接材料和焊縫檢測，伊犁鍍鋅槽鋼哪家好，相對來說也節(jié)約了成本。工字鋼可加工成T型鋼，蜂窩梁可經(jīng)組合形成各種截面形式，極大滿足工程設計與制作需求，伊犁鍍鋅槽鋼哪家好。2、缺點：造價也會更高，而且工字鋼占用的空間層高也更大。不是什么建筑環(huán)境都是可以用工字鋼的。</p><div

style="text-indent:25px"> 一般來講型材就是有一定截面形狀和尺寸的材料，很多不同種類的材料如：鋼鐵、鋁合金、銅合金包括木材等都有自己的型材系列。下面我們以鋼材中型鋼為例介紹一下型材。型鋼是一種有一定截面形狀和尺寸的條型鋼材。型鋼分類：按照鋼的冶煉質量不同，型鋼分為普通型鋼和質量型鋼。普通型鋼按現(xiàn)行金屬產(chǎn)品目錄又分為大型型鋼、中型型鋼、小型型鋼。根據(jù)截面復雜程度型鋼又可分為復雜截面型鋼與簡單截面型鋼，復雜截面型鋼有工字鋼、槽鋼、H型鋼、鋼軌、窗框鋼、彎曲型鋼等；簡單截面的型鋼有方鋼、圓鋼、線材、扁鋼、彈簧扁鋼、角鋼、三角鋼、六角鋼、弓形鋼、橢圓鋼等。板材概述板材的分類：按厚度分類：薄板中板厚板特厚板。按生產(chǎn)方法分類：熱軋鋼板冷軋鋼板。按表面特征分類：鍍鋅板（熱鍍鋅板、電鍍鋅板）鍍錫板復合鋼板彩色涂層鋼板！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="伊犁鍍鋅槽鋼哪家好" src="http://tyunfile.71360.com/UploadFile/xjzzyt/637206745616054687/9041778.jpg"></div><p style="text-indent:25px">工字鋼的種類有熱軋普通工字鋼、輕型工字鋼和寬平行腿工字鋼（H型鋼）。我國熱軋普通工字鋼的腰寬為100～630mm，表示為No.10～No.63，腿內側壁斜度為1：6。軋制工字鋼的孔型系統(tǒng)有直軋孔型系統(tǒng)、斜軋孔型系統(tǒng)和混合孔型系統(tǒng)。工字鋼還可以采用特殊軋法。（1）直軋孔型系統(tǒng)。直軋孔型系統(tǒng)是指工字鋼孔型的兩個開口腿同時處于軋輥軸線的同一側，腰與軋輥軸線平行的孔型系統(tǒng)。其優(yōu)點是軋輥軸向力小，軸向竄動小，不需工作斜面，孔型占用輥身長度小，在輥身長度一定的條件下可多配孔型。（2）斜軋孔型系統(tǒng)。這種孔型系統(tǒng)是指工字鋼孔型的兩個開口腿不同時處于腰部的同一側，腰與水平軸線有一夾角。（3）混合孔型系統(tǒng)。根據(jù)軋機和產(chǎn)品的特點，為充分發(fā)揮各自系統(tǒng)的優(yōu)點，克服缺點，往往采用混合孔型系統(tǒng)，即兩種以上系統(tǒng)的組合。如成品孔和成品前孔采用直腿斜軋孔型系統(tǒng)，其他孔型采用彎腿斜軋系統(tǒng)；或者粗軋孔采用直軋系統(tǒng)，3～4個精軋孔采用直腿斜扎孔等。（4）特殊軋法。由于某種原因采用通常的軋制方法難以軋出要求的工字鋼時，可采用特殊軋法，充分利用不均勻變形和孔型設計的技巧。</p><div
