建筑鋼結(jié)構(gòu)的經(jīng)濟(jì)性能一直是大家最為關(guān)注的一個(gè)問題。如何控制工程造價(jià)，充分發(fā)揮鋼結(jié)構(gòu)建筑技術(shù)經(jīng)濟(jì)上的綜合優(yōu)勢(shì)，工程設(shè)計(jì)階段是關(guān)鍵階段。探討在設(shè)計(jì)階段材料選用，提高建筑經(jīng)濟(jì)性能的可行性。

The economic performance of building steel structure has always been the most concerned issue. How to control the project cost and give full play to the comprehensive advantages of steel structure building technology and economy, the engineering design stage is the key stage. Discuss the feasibility of material selection in the design stage to improve the economic performance of buildings.

材料選用方面

Material selection

由于我國鋼產(chǎn)量已經(jīng)突破兩億噸，鋼材品種更趨于多樣化。各種新型建材，如輕質(zhì)保溫墻板、彩涂壓型鋼板、樓承板等不斷開發(fā)出來并推廣應(yīng)用。建筑鋼結(jié)構(gòu)在設(shè)計(jì)階段材料的選擇上有了更大的空間。材料選擇不同，工程直接費(fèi)不同，總造價(jià)不同。設(shè)計(jì)階段合理選擇建筑材料，控制材料單價(jià)或工程量，是控制工程造價(jià)的有效途徑。試舉例如下：

As China's steel output has exceeded 200 million tons, steel varieties tend to be more diversified. All kinds of new building materials, such as lightweight insulation wallboard, color coated pressed steel plate, floor plate and so on, are constantly developed and applied. Building steel structure has the greater space in the selection of materials in the design stage. Material choice is different, the project direct cost is different, the total cost is different. In the design stage, the unit price or quantity of materials are an effective way to control the project cost. Examples are as follows:

白色彩涂鋼板：彩涂鋼板一般用于輕鋼廠房屋面板和墻面板，有不同板型、不同基板厚度和鋼號(hào)、不同鍍鋅板類別和鍍鋅層厚度以及不同的彩涂層類別，在形式上又可選用單板、保溫復(fù)合板、單板加內(nèi)保溫層等，其中保溫層又有超細(xì)玻璃絲棉、硬質(zhì)巖棉、聚苯乙烯等類別及厚度的不同，這些不同都造成單方材料價(jià)格的差異，從而影響廠房工程總造價(jià)。所以設(shè)計(jì)時(shí)要根據(jù)廠房性質(zhì)、大氣環(huán)境等因素綜合考慮，合理選用板材，控制工程造價(jià)。

White color coated plate: color coated steel plate generally used for light steel mills building panel and wall panel, have different plate, different substrate thickness and steel, different galvanized plate category and galvanized layer thickness and different color coating category, in the form and can choose veneer, insulation composite plate, veneer and internal insulation layer, etc., the insulation layer and ultrafine glass wool, hard rock wool, polystyrene category and the thickness of different, these different cause unilateral material price difference, thus affect the plant project total cost. So the design should be based on the nature of the plant, atmospheric environment and other factors, reasonable selection of plate, control the cost of the project.
