Steel structure workshop roof construction scheme
Steel structure workshop roof construction scheme
The construction method
1. Construction process arrangement
1.1 Roof: color board approach – construction platform – gutter installation – lower board installation – insulation cotton laying – roof board installation – roof cap installation – gable flooding installation – gutter waterproof treatment – sporadic cloth.
1.2 Wall: color board approach — construction platform — wall wiring installation — laying insulation cotton — inner wall panel installation — flooding installation — door and window package installation — project acceptance.
2. Steel structure color plate:
2.1 Installation of gutter
Workshop wheelbase is 6m each span gutter divided into two sections, using welding joints, in order to avoid welding deformation, the joint first with indirect spot welding, until the joint is completely flat in full welding. After qualified, hoisting and welding will be carried out in turn.
2.2 Roof slab construction method
The roof bottom plate is Q900 type plate, which is fixed on the upper plane of purlin and then laid with rock wool insulation layer. Lay from axis 16 to axis 1.
In laying rock wool at the same time laying roof roof, in the installation of roof board should pay attention to the horizontal flatness of the board, in laying the first piece of steel tape measure out the parapet to the steel beam parallel size. And positioning.
When laying 3-5 roof panels, measure whether the width of the ridge and cornice is the same to ensure that the roof is parallel and ensure that the maximum slope does not exceed the specification 20mm.
2.3 Gable flooding. Roof ridge cover plate construction method
After the roof board installation is completed, the first ridge eaves to do flooding along the waterproof treatment, in the installation of the ridge cap, in the installation of the ridge cap lap part length is not less than 100mm, and connected with rivets, in the ridge cover after the completion of all exposed rivets full play sealant.
2.4 Wall color board installation method
When installing the wall panels, install the outer wall panels, which are fixed on the outside of the purlin. After fixing the first outer wall panels, ultra-straight laying and ultra-flat will be carried out, and the lower flooding will be leveled straight, and then installation will be carried out successively. After installing the outer wall panels, In order to prevent sagging of thermal insulation surface, rock wool nail should be laid on the outer wall panel in large area to ensure that the thermal insulation surface is fixed without sagging, and the inner wall panel should be fixed in the inside of the purlin and the laying of thermal insulation surface. The practice is the same as the outer wall.
Trench waterproof treatment – sporadic repair – project acceptance
It is the upper, middle and lower sections of the plate. The middle joint is connected by pressure type side drawing plate. Each span can be installed independently.
