Sanle fiber cement board is a new type of green environmental
protection board with excellent performance, such as fireproof,
moisture proof,insect-resistant ant, easy working, thermal
insulation,low deformation coefficient and durable. It is widely
used for partition wall, exterior cladding and floor in offices,
hospitals, factory building, villas,theaters and various art
buildings.

board preparation: according to the size and design requirements,
installing the supporting aluminum accessories( six aluminium
accessories per sheet) on the back of fiber cement board ( maximum
cross section size is 2780 * 1220 mm). Making cross line according
to the vertical distance ( 600 mm ) between the transverse keels
and length of fiber cement board uniform size, then fixing
supporting aluminum fasteners at the intersection,using 10 mm long
and 4 mm thick stainless steel screws.2. Construction wall
preparation: cleaning up the wall surface, and then marking out the
position lines and partition lines of the steels according to the
design drawings and actual needs.3. Wire hanging: vertical wire
hanging should use the ∮1.0-∮1.2 size steel wire, with 8-10 kgs
weight lower counterweight iron, and the upper end is hung on the
special wire hanging Angle iron frame. The angle iron frames are
fixed on the top corners of the wall with expansion bolts, and
marking on the top and bottom of the control line.4. Keel
installation: first fixing 50×50×4 angle iron (with adjustable
hole) on the structural surface with ∮8 expansion bolt, that
horizontal distance between the angle iron and the 50×50×3.5
vertical square steel tube on the angle steel is 800mm. When
installing the vertical square steel tube, it must be checked by
hanging steel wire from top to bottom to detect its
Perpendicularity. After that, installing the fastening angle iron
and the transverse aluminum keel (with 600mm spacing). The
connection between angle iron, square steel tube and transverse
keel is made with ∮10 bolts. Last, using the infrared level meter
to detect whether the horizontal aluminum keel is horizontal, and
the steel line to detect whether it is vertical.5. Fiber cement
board installation: mounting the advance processing board on the
keel according to the design drawings, and using aluminum
accessories to connect the panel and keel. Hanging lightly the same
level layer fiber cement boards on the keel, and then adjusting the
horizontal and vertical degree of board through upper and lower
steel wires. After that, checking the boards seam, whose width
should be uniform according to the requirements of design. Last,
tightening the stainless steel screws (20mm long and 6mm thick) on
the complete set of aluminum accessories.6. Board joint treatment:
using the fiber cement board powder mixing glue to fill the seam,
and then painting with special coating twice. When filling the gap,
it is necessary to pay attention to the uniform and full filling.1.
The top and bottom keels are fixed respectively top floor and on
floor with expansion bolts.2. The vertical keel should be aligned
well according to the requirement (generally being 612 mm) with
laterally supporting keel installed.3. Cutting the board material
to the dimensions needed (about 10mm lower than wall height)4.
Board material is fixed on keel in anchoring seam way with tapping
screw: the interval of tapping screw is generally about 200~250mm
with screwssinking 0.5mm under the board face.5. The expansion seam
of about 4mm between boards should be kept.6. The shrouding should
be fixed from the middle to the four sides and cannot be operated
at multipoint simultaneously to avoid generating inner stressto
make board material bucking.7. Before board being packaged and
fixed, depending the needs, glass cotton or rock cotton can be
filled.Selection of steel structure keel:1. The span is within 8m:
15H steel for the main beam, #10 channel beam and #63 angle iron
for the secondary beam.2. No embedded parts shall be fixed with
expansion bolts.3. Abundant space can be used upper and lower beam
structure, space is not enough can be used plane structure.Steel
structure welding requirements: There are must be at least three
sides of the welding, the top surface can not be welded.Floor board
Installation:1. Before laying the boards, the welding seam on the
top surface must be polished flat and the welding spatter must be
cleared away.2. The longitudinal direction of the boards should be
parallel to the main beam.3. Any edge o
