型鋼是一種有一定截面形狀和尺寸的條型鋼材，是鋼材四大品種(板、管、型、絲)之一。根據(jù)斷面形狀，型鋼分簡單斷面型鋼和復(fù)雜斷面型鋼(異型鋼)。簡單斷面型鋼指方鋼、圓鋼、扁鋼、角鋼、六角鋼等；復(fù)雜斷面型鋼指工字鋼、槽鋼、鋼軌、窗框鋼、彎曲型鋼等。型鋼一般用于機械加工、結(jié)構(gòu)連接等。薄鋼板是平板狀，矩形的，可直接軋制或由寬鋼帶剪切而成。鋼板按厚度分，薄鋼板<4毫米（最?。?，厚鋼板4~60毫米，特厚鋼板60~115毫米。鋼板按軋制分，分熱軋的和冷軋的。薄板的寬度為500~1500毫米；厚的寬度為600~3000毫米。薄板按鋼種分，有普通鋼，南陽專業(yè)樓梯安裝、優(yōu)質(zhì)鋼、合金鋼、彈簧鋼、不銹鋼、工具鋼、耐熱鋼、軸承鋼、硅鋼和工業(yè)純鐵薄板等；按專業(yè)用途分，有油桶用板、搪瓷用板、防彈用板等；按表面涂鍍層分，有鍍鋅薄板、鍍錫薄板、鍍鉛薄板、塑料復(fù)合鋼板等。厚鋼板的鋼種大體上和薄鋼板相同。在品各方面，除了橋梁鋼板、鍋爐鋼板，南陽專業(yè)樓梯安裝，南陽專業(yè)樓梯安裝、汽車制造鋼板、壓力容器鋼板和多層高壓容器鋼板等品種純屬厚板外，有些品種的鋼板如汽車大梁鋼板（厚）、花紋鋼板（厚）、不銹鋼板、耐熱鋼板等品種是同薄板交叉的。另外，鋼板還有材質(zhì)一說，并不是所有的鋼板都是一樣的，材質(zhì)不一樣。</p><div

style="text-indent:25px">樓梯梯段是由若干踏步組成，每個踏步由踏面和踢面組成。樓梯梯段是供人通行的，因此踏步尺寸要與人行走有關(guān)，即踏面寬度與人的腳長和上下樓梯時腳與踏面接觸狀態(tài)有關(guān)。踏面寬300mm時，人的腳可以完全落在踏面上，行走舒適。當(dāng)踏面寬減少時，人行走腳跟部分可懸空，行走就不方便。一般踏步面寬不宜小于240mm。踢面高度的確定與踏面寬度有關(guān)。一是踢面高度和踏面寬度之比決定樓梯坡度，二是踢面高度和踏面寬度之和要與人的跨步長度相吻合。可按下列經(jīng)驗公式計算踏步尺寸 2hb600～620mm或hb450mm式中h表示踏步踢面高度；b表示踏步踏面寬度。600～620mm表示一般人的步距。當(dāng)踏步尺寸較小時，可以采取加做踏口或使踢面傾斜的方式加寬踏面。踏口的挑出尺寸為20～25mm，這個尺寸過大時行走不方便。</p><div style="width:100%;text-align: center;"><img style="max-width:

鋼結(jié)構(gòu)樓梯上可不可以鋪設(shè)大理石？當(dāng)然可以鋪設(shè)大理石踏步。但樓梯踏步鋼板和石材之間的結(jié)合層應(yīng)該妥善處理。通常需要解決好兩個問題，一是共振問題，二就是結(jié)合強度的問題。施工中比較成熟的辦法，一般先在鋼板踏步上焊上兩道10MM鋼筋條（或鋼帶），再焊上鋼絲網(wǎng)。然后1:3水泥砂漿找平，等干硬以后，在用水泥砂漿把大理石貼上。也有直接焊接鋼絲網(wǎng)然后鋪水泥砂漿，貼大理石的。這樣就可以避免大理石的脫落，影響鋼結(jié)構(gòu)樓梯的美觀。
