Bar grating panel

View as Markdown

Welded / pressure-locked steel bar grating panel modelled bar by bar: bearing bars along X at the set pitch (30 × 3 mm at 30 mm by default), cross bars at 100 mm, edge banding, optional 100 mm kick plates on the long edges and saddle clips at the corners. Bottom on y = 0, walking surface at y = depth, centred on the origin; the bearing bars span along X.

Installation

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add grating-panel

Copies structure/grating-panel.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { GratingPanel } from './components/deck-twin/structure/grating-panel'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <GratingPanel />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

P&ID

Plan view: an area filled with close parallel lines (the bearing bar direction), sometimes a cross-hatch, with the panel outline; solid plate is drawn plain or with a checker-plate hatch.

Layout plan convention (structural / plot plan drawings) (floor plan hatch)

Only on structural and layout drawings. The hatch direction shows the span direction of the bearing bars.

For agents

Machine-readable entry with props, ranges, defaults and ports:

$npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info grating-panel

Or fetch /r/grating-panel.json, or copy a ready-made instruction:

Add the Deck Twin "Bar grating panel" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add grating-panel` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info grating-panel` for its props, ranges and ports. Render <GratingPanel /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
