GRC Component Installation Ten Key Steps Full Process

GRC component installation ten key steps: ① measure layout (3D control network establishment); ② base and embed check (load capacity review); ③ keel installation (welding and anti-corrosion treatment); ④ component entry acceptance (number check and damage check); ⑤ pre-arrangement trial assembly (key component ground pre-assembly); ⑥ formal installation (top-down or by zone); ⑦ connection node fix (torque and anti-fall check); ⑧ joint treatment (backing + sealant); ⑨ surface repair and clean; ⑩ sub-item acceptance (including water spray test). Each step has quality control point, missing any step will放大 into quality problem later.

Core Points

• Layout → base → keel → acceptance → pre-arrangement → install → fix → joint → finish → acceptance ten-step loop
• Key control points: keel anti-corrosion, connection torque, joint depth and width
• Acceptance includes water tightness (water spray) test

Important Notes

Industry iron rule 'three-tenths material seven-tenths installation' — the same batch of components, different installation teams' final effect can differ by one grade. When choosing manufacturer, in-house installation team is worth more than 5% cheaper subcontract model.

GRC component installation ten steps: measure layout, base and embed check, keel installation, component entry acceptance, pre-arrangement trial assembly, formal installation, node fix, joint treatment, finish and sub-item acceptance; each step set quality control point to form closed-loop management system.

Myth: GRC installation is 'just hanging the component up.' Installation essence is 'gradual digestion of error': structure construction error ±20 mm level → keel level to ±5 mm → component installation precision ±2 mm — each step creates precision baseline for next step. Teams that skip layout and directly install, the joints must not align.

Steps One to Four: Lay Foundation Right

Measure layout: use total station to establish 3D control network, pop out component installation baseline (custom-shaped project extract model control point coordinates); base check: embed position deviation recheck (over-tolerance handling plan), concrete strength confirmation; keel installation: weld per drawing, weld anti-corrosion recoat (missed coating is corrosion starting point), vertical flatness verification (within ±3 mm); entry acceptance: check component number against installation drawing, check transport damage (damaged component register, forbid injured on wall).

Steps Five to Seven: Core Three Installation Steps

Pre-arrangement trial assembly: complex component (corner, curved surface, first piece) ground pre-assembly, verify joint and cumulative error; formal installation: top-down or按 flow section proceed, each panel position by number (custom-shaped piece installed wrong position = curved surface break), elevation and front-back dual control; node fix: tighten per design torque, anti-fall card installed in place, record one by one (panel number - installer - date traceable card). Qinglong's in-house installation team executes process card system — each step leaves trace, responsibility to person.

Steps Eight to Ten: Finish Decides Appearance

Joint treatment: clean joint debris → backer foam rod (control joint depth) → sealant application (width-to-thickness 1:1-2:1, continuous uniform no break); finish: transport and hoist bump repair (same color same material), surface clean remove sealant trace; sub-item acceptance: appearance (uniform joint, consistent color, no damage) + function (water spray test check leakage, pull-out test spot check connector) dual-dimension acceptance. Three-tenths material seven-tenths installation, last three steps are where 'seven-tenths' comes from.

Comprehensive Comparison

• Precision transfer: structure ±20 mm → keel ±5 mm → component ±2 mm
• Key control points: keel anti-corrosion / connection torque / joint depth and width
• Acceptance dual dimension: appearance + function (water spray / pull-out)
• Management tools: process card + traceable installation record
