2nd, prepare construction material, including GRC products outside, cement mortar, acrylic type adhesive, fluid sealant, antirust paint and The supplementary materials such as welding rod；Prepare construction equipment:It is cutting machine, electric welding machine, spirit level, horizon rule, tape measure, ink line case, angle square, straight Ruler, clearance gauge and linen thread etc..
3rd, the attachments such as dirt, mortar block and the rubbish of stair step base are removed, chipping processing is made in local prominent place. Check whether the quality of base meets the requirements.
4th, in the acrylic type gluing oxidant layer of substrate surface, uniformly one layer of 1~2mm thickness of smearing；Cover the rubber slab of 5mm thickness Protective layer, and it is levelling with horizon rule；
5th, in base's face pop-up horizontal line, vertical line and GRC product location lines, it is necessary to accomplish smooth vertical and horizontal, part and part Between gap uniformity, gap control in≤5mm.
6th, GRC cover boards are carried out to fix, weld；Again GRC cover boards installation effect is carried out with horizon rule；
7th, hanging GRC products, spiral stairs form of marking time carries out from lower to upper in order, suitable for reading to be subject to horizontal line, bottom Hang up properly after, corrected with guiding ruler inspection, must not there is the phenomenon that uneven up and down, gap control is in 3~5mm between product.
8th, after seam crossing adds acrylic type adhesive to mix thoroughly using cement mortar, divide 2~4 times according to the thickness of covering cover board When embedding full seam, each filleting interval 2~4 are small, ensure that caulking agent fully cures.
9th, one layer of 3~6mm thickness rubber slab is padded in GRC products and base junction, to separate GRC plates and base's steel construction Contact directly, and with sealing compound filleting.
Fastener used in fixation described in step 6 use zinc-plated processing, embedded part exposed parts, fumigation free, reinforcing bar and Weld seam etc. makees preservative treatment, generally red lead anti-corrosive paint.
Welding needs control sequence and weld bead height described in step 6, meets design requirement, does pullout tests if necessary.
Above-mentioned construction method carries out acceptance of concealed work work.
The quality inspection and evaluation of above-mentioned construction method：
1st, quantity is checked, ladder is marked time at each inspection layer selective examination three for an inspection layer per floor, and often place marks time selective examination 3~5 Point contacts gap and pedal tread on an empty stomach including pedal surrounding.
2nd, the model of GRC components, accessory and connector, specification and technical conditions meet design and related code requirement.GRC Component strength meets design requirement, surface free from flaw.The method of inspection:Check component dispatch from the factory documentary evidence, qualified product card, Check cement mortar block Measurement Report.Observation checks component surface.
3rd, GRC components installation method and installation quality should meet design requirement, firmly install non-loosening.The method of inspection:It sees Inspection is examined, with hand jog.Check concealment acceptance list.
4th, seam meets design and related code requirement, component are firmly bonded, free from flaw.Visual examination.
The advantage of the invention is that：With total quality is light, combination flexibly, convenient and quick construction, without secondary decoration, easily In the series of advantages such as being consistent with periphery decoration style.Using this construction technology, it is existing to environmental protection to meet country It is required that the application of this construction technology, method, whether old industry cleaning or promoted in the range of the whole city will generate huge Economic benefit and social benefit.
