Installation of roofing panels and cladding panels
There is no joint in the longitudinal direction of the roof panel, and the roof panel production site and finished product stacking site should be left at the end of the hill wall on the construction site. The roof panels will be transported to the roof by crane, and the installation order should be considered to be conducive to the dominant wind direction of the region and laid from one end of the plant span by span. The construction order of roof panels will be determined according to the site conditions.
● Install the first panel against the side of the hill wall first, when the first roof panel is fixed in place, pull a continuous collinear line at the eaves of the roof, this line and the first roof panel will become the guiding reference for the quick installation and correction of the subsequent roof panels, then each roof area should be tested periodically during installation by measuring the width of the roof panel that has been fixed. Measure once at the ridge line (or top of the panel) and once at the gable (or bottom of the panel) to ensure that there is no movement and scalloping and that the roof panels are parallel and perpendicular.
● The steel structure project roof panel bending parts mainly have the ridge inside and outside closing, sealing board and ridge hill wall gable closing and so on (pay attention to the construction sequence), these color plate bending parts and color plate connection with aluminum rivets, color steel bending parts accessories should be neat, beautiful, meet the waterproof effect, after all fixed, with sealant play a section and then lightly rub to make even, flood plate and other waterproof points should be coated with sealant.
1、Roof panel installation
The construction order is decided by the sequence of the structure with conditions, and the normal construction order is from one end of the roof to the other end.
According to the structure of the metal roofing system and the installation procedure of the system, the construction procedure of this project is shown in the following page.
● Build a walkway on the purlins to ensure construction safety and construction progress.
● For installation, lift the panels onto the roof with a crane (manual lifting method can also be used). The lifting belt must use flexible liftings such as a nylon belt or cloth belt, and a steel belt must not be used. A protective wooden strip should be inserted between the package and the sling or package, thus preventing the deformation along the board.
●The plates should be handled gently to avoid bumping and dragging on the ground to avoid damaging the plates.
● The surface of the board should be cleaned first before installation, and then check whether there are residues on the board surface, such as cleaning agents and water to clean the mixture. And dry the surface with a dry cloth.
● The laying direction of the board must be laid against the dominant direction. ●The line must be popped up at any time during the roof panel installation to prevent accumulated error.
●During roof panel installation, the ridge cover and waterproof plug (or roof panel upper bend) must be installed at the same time to keep up.
●The board is more sensitive to concentrated load, so the construction personnel must not gather together during the construction of roofing color board to avoid the local damage of the board caused by the concentrated load.
When installing roofing panels, adopt side lifting and transport installation, at least finish installing the boards on the lifting roof on the same day, and take corresponding measures to prevent falling for all boards that are not installed on the same day.
Quality requirements: The size of the press board is correct, the surface is clean, there is no perceptible bump or fold, the joints are straight, the vertical and horizontal laps are straight, the joints are even and neat, and there is no warpage or mis-drilled holes.
