Color steel enclosure is a kind of profile for site maintenance and barrier with the outside world after processing by machine molding, painting and bending. It is suitable for construction site, highway maintenance and construction site. It is a light barrier plate with the characteristics of fire prevention, waterproof, moisture-proof and light weight.

彩钢围挡特性不需砌砖，更不需水泥墩筑基，不易褪色不易变形不需经常维修，运用时，不论是装置还是拆卸都快捷便当，而且还能够重复运用。其强度、耐性以及性都是比拟好的，颜色丰厚，价钱实惠。彩钢围挡装置彩钢围挡装置前普通是土建已构成托付砖砌或砼浇捣的下部根底。

The color steel enclosure does not need bricklaying, let alone cement pier foundation construction, is not easy to fade, is not easy to deform, and does not need frequent maintenance. When in use, it is fast and easy to install or disassemble, and can be reused. Its strength, durability and are relatively good, rich in color and affordable. Color steel enclosure device in front of color steel enclosure device, it is generally civil engineering that has formed the lower foundation entrusted with brick masonry or concrete pouring and tamping.

护栏可采用机械式胀栓、化学螺检等方式将立柱钢衬底板固定在下部根底的部位作直线均布，如彩钢围挡的下部根底尚未构成，倡议将立柱钢衬增加长度直接预埋在墙体内，待墙体养护期后即可正式施工；或预制预埋件敷设在墙体平面以后将立柱钢衬用电焊方式与预埋件焊接。

The guardrail can adopt mechanical expansion bolt, chemical screw inspection and other methods to fix the column steel lining bottom plate at the center of the lower foundation for straight-line uniform distribution. If the lower foundation of the color steel enclosure has not been formed, it is suggested to increase the length of the column steel lining and directly embed it in the wall, and the formal construction can be carried out after the wall maintenance period; Or after the prefabricated embedded parts are laid on the wall plane, the column steel lining is welded with the embedded parts by electric welding.

这二种方式特性是较螺栓衔接更为结实，但预设时必需留意直线与程度线，立柱钢衬的间距须与设计尺寸分歧，预装配的半废品能与之衔接，在直线间隔全段拉上下限二道平行线作装置调整基准。护栏装置完工后上下端的平直度。

The characteristics of these two methods are stronger than bolt connection, but attention must be paid to the straight line and degree line during preset. The spacing of column steel lining must be different from the design size. The pre assembled semi-finished products can be connected with it. Two parallel lines at the upper and lower limits shall be drawn at the straight-line interval as the device adjustment benchmark. Straightness of upper and lower ends after completion of guardrail device.
