The utility model discloses a large-scale steel construction cornices roofing structure's construction steps as follows:
(1) Eaves purlin installation.
Cornice purlines mainly bear the force of profiled steel sheets and play a role of a planar stress structure. The installation of eaves purlin will control the outward appearance and the inspection of detecting a flaw of welding seam, the axis displacement of steel eaves purlin, radian, levelness, the straightness that hangs down in striding, side direction bending etc..
(2) And (5) installing the profiled steel sheet.
The profiled steel sheet is an aluminum-zinc-magnesium plated profiled steel sheet with the thickness of 1.2mm, and mainly plays a role of a roof truss for sealing a main body structure. The installation of profiled steel sheets is to control the length of longitudinal and transverse lap joints, the condition of seams and the like.
(3) And (5) mounting a supporting framework.
The supporting framework is mainly used as a stress framework to bear the pressure of the supporting plate and the fixed support of the protection plate. The connection mode of the horizontal purlines and the connecting pieces of the supporting framework is fixed by welding, and the connection mode of the longitudinal purlines and the horizontal purlines is characterized in that one end of each purline is welded and the other end of each purline is fixed by a bolt. Horizontal purlin spot welding earlier, full welding again after adjusting the position, vertical purlin penetrates the bolt, does not screw up earlier, treats one end welding completion, and adjacent purlin top surface difference in height is fastening bolt when within 2mm, if not flat through the backing plate adjustment after fastening again, should adjust into the unanimity with double-phase adjacent purlin top surface as far as possible during the installation.
(4) The bearing plate is installed.
The support plate mainly functions as a plane carrier for providing stress for laying the waterproof roll. The integral shape of the whole roof supporting plate must meet the shape requirement and performance requirement of roofing engineering. The anchoring is reliable, the installation is smooth, the plate gap is tightly contacted, and the plate surface is clean.
(5) Waterproof system of waterproofing membrane + guard plate.
Accurately paying off according to a prearranged drawing, and laying the waterproof roll in advance, wherein the waterproof roll is lapped by water and staggered joints when laid. The longitudinal lap width of the coil stock is 80mm, and the transverse lap width is 120mm.
The fixing support of guard plate installation mainly provides the atress supporting role for the guard plate to can fix waterproofing membrane to a certain extent. According to the installation drawing of the roof plate, the measurement of the position control points of the fixed seat, the measurement of the control lines for installing the bottom plate, the measurement of the fixed support, and the straightness and parallelism of the support installation and the height difference control of the interval support should be noticed.
The protection plate adopts 1.0mm thick aluminium magnesium manganese alloy roof boarding, is a neotype roof boarding, because structural strength is moderate, resistant weather, resistant stain, easily advantages such as welding process of bending, generally accepted as the roofing of architectural design life more than 50 years, after the roof boarding position adjustment, carries out the lockstitching interlock with the machine of lockstitching a border. The undercut is required to be continuous and flat, and cannot be twisted or cracked, and the roof panel in place on the same day must be undercut.
After the roof panel is installed, a honeycomb aluminum plate and an aluminum alloy decorative strip with the thickness of 25mm are installed on the roof panel.
