工程建設常用的圍擋類型
Types of enclosure commonly used in engineering construction
每個地區(qū)對建筑區(qū)域的外殼都有不同的要求,包括外殼的材料、類型、高度等。具體情況需要詳細分析。接下來,我將分析工程建設中常用的圍護結(jié)構(gòu)類型。。
Each area has different requirements for the shell of the building area, including the material, type, height, etc. The specific situation needs to be analyzed in detail. Next, I will analyze the types of envelope commonly used in engineering construction..
金屬圍擋:
Metal enclosure:
此類外殼的主要材料仍由彩鋼板組成,標準版金屬外殼(高2米、寬3.6米、厚0.3毫米)的仍主要受彩鋼厚度影響盤子。金屬外殼強度高于PVC外殼,外觀更高,光潔度更高,使用壽命可達5年以上。特別是改進后的新型龍骨扣彩鋼外殼采用1.2厚G型鋼作為龍骨,大大增強了外殼的抗風能力,使安裝更加輕松方便。
The main material of this kind of shell is still composed of color steel plate, and the price of standard metal shell (2m high, 3.6m wide and 0.3mm thick) is still mainly affected by the thickness of color steel. The strength of metal shell is higher than that of PVC shell, with higher appearance, higher finish and service life of more than 5 years. In particular, the improved new keel buckle color steel shell adopts 1.2-thick G-shaped steel as the keel, which greatly enhances the wind resistance of the shell and makes the installation easier and convenient.
PVC圍擋:
PVC enclosure:
別名(市政圍欄、工程圍欄、工地圍欄、塑料圍欄、市政圍欄或圍欄)
Alias (municipal fence, engineering fence, site fence, plastic fence, municipal fence or fence)
這種的主要材料是聚乙烯和鈣粉。標準版PVC外殼(高2.5米,寬3.0米,厚2.2厘米)影響PVC外殼主要是因為PVC表面的材質(zhì)。乙烯和鈣粉的組合沒有未成型的板面。好的PVC板表面韌性好,不易斷裂變脆,光潔度高,易清潔,外觀阻燃。這種外殼可以使用三年以上。
The main materials of this are polyethylene and calcium powder. The standard PVC shell (2.5m high, 3.0m wide and 2.2cm thick) affects the price of PVC shell mainly because of the material of PVC surface. The combination of ethylene and calcium powder has no unformed plate surface. Good PVC board has good surface toughness, not easy to break and become brittle, high finish, easy to clean and flame retardant appearance. The shell can be used for more than three years.

鐵皮圍擋:
Iron sheet enclosure:
別名(彩鋼圍欄、簡易圍欄、移動圍欄)
Alias (color steel fence, simple fence, mobile fence)
顧名思義,這種外殼的主要材料是彩鋼板,而鐵皮外殼的還是由彩鋼板的厚度決定的,是根據(jù)個別客戶的剛性需求而定的。鐵柵欄多用于短期施工,或需要經(jīng)常拆除挪用。建議是好使用一年。拆裝方便,便宜。
As the name suggests, the main material of this kind of shell is color steel plate, and the price of iron sheet shell is determined by the thickness of color steel plate, which is determined according to the rigid demand of individual customers. Iron fences are mostly used for short-term construction or need to be removed and misappropriated frequently. The suggestion is to use it well for one year. Convenient disassembly and cheap price.
泡沫圍擋
Foam enclosure
泡沫圍擋的主要材料是塑料泡沫。泡沫外殼的立柱與金屬外殼沒有區(qū)別,只是泡沫夾芯板有一個卡扣設計,用于固定外殼的泡沫夾芯板表面。泡沫夾芯板一般為5CM厚,中間為泡沫塑料,兩側(cè)為彩鋼瓦。彩鋼瓦的厚度從0.5mm到3mm不等,規(guī)格和也不同。您可以根據(jù)自己的實際需要購買。
The main material of foam enclosure is plastic foam. There is no difference between the column of the foam shell and the metal shell, except that the foam sandwich panel has a snap design, which is used to fix the surface of the foam sandwich panel of the shell. Foam sandwich panels are generally 5cm thick, with foamed plastic in the middle and colored steel tiles on both sides. The thickness of colored steel tiles ranges from 0.5mm to 3mm, and the specifications and prices are also different. You can buy according to your actual needs.
圍擋護欄廠家認為工程建設買什么樣的護欄好,這個要根據(jù)當?shù)氐某墙ㄒ?guī)定或者市容管理規(guī)定來決定,所以需要根據(jù)實際情況來分析。欲了解更多信息,請訪問網(wǎng)站www.sud-inc.com
What kind of guardrail the guardrail manufacturer thinks is good for engineering construction should be determined according to the local urban construction regulations or city appearance management regulations, so it needs to be analyzed according to the actual situation.
