Utendørs LED-reklameskilt i stål: Sjekkliste for tegninger

DOIT VISION Ingeniørteam

The first drawing a billboard fabricator needs is the approved cabinet layout. It fixes the active dimensions, mounting interfaces and service side. A price based only on screen area leaves the fabricator to guess where the display attaches and how parts will come out later.

Start with the equipment layout

Use the selected standard Square 960 cabinet drawing. Mark columns, rows, front orientation, connection points and the boundary between active image and trim. For example, five 960 mm cabinets span 4.80 m of active width. A five-metre architectural opening is a different dimension.

Tegningsinndata Hvem leverer det Hva det løser
Cabinet schedule and interface drawing Display supplier Cabinet size, weight and fixing locations for the selected build
Survey and existing support details Nettstedsteamet Where the proposed frame meets the building or pole
Service and cable routes Installer and display supplier Access to parts, connections and isolators
Site design and fabrication release Project structural lead and fabricator Which reviewed revision may be fabricated

Mark the interfaces that must stay accessible

Draw one cabinet in section at an edge and another at an interior position. Show which way the module leaves the face, where the control box opens and where cables enter. A support member that clears the cabinet outline can still obstruct a latch or the path of a replacement power supply.

Separate design support from the steelwork order

DOIT VISION provides product drawings, steel-structure CAD drawings, wiring diagrams and installation instructions for outdoor display projects. Installation plates and screws are identified by item and quantity on the order. Put fabrication, local structural review, transport of the steel and site erection on separate scope lines with a named responsible party.

The site structural professional needs the actual building or foundation information and local design conditions. Cabinet weight is one input to that review. A fixed percentage added to display weight cannot establish the capacity of the complete support.

Release one drawing set to all parties

Put the display model, layout revision and orientation on the frame, power and cabinet drawings. Before fabrication, compare hole locations, clear openings and cable entry against the same revision. If the cabinet changes, have the fabricator mark affected interfaces before authorising work on the revised set.

FAQ
What information is needed for a support-frame drawing?
A dimensioned elevation, installation height, face count, cabinet grid and photographs of the existing support are useful starting inputs. The selected cabinet drawing then supplies fixing points and weight. Mark which surfaces can be reached after installation and who will review the site connection. A photograph is useful for orientation but does not establish structural capacity.
Does cabinet weight define the entire structural load?
Cabinet weight describes the equipment, not the response of the entire structure. Give the project structural lead the equipment schedule, frame concept, site geometry and support information. That person can specify the additional site data needed for review. Keep the approved support design separate from the supplier’s cabinet weights and illustrative equipment layouts.
Can an existing billboard frame be reused?
Reuse is a design decision for the existing structure and the proposed new equipment. Survey the frame, record its condition and compare its actual interfaces with the new cabinet drawing. Even a display of the same active area can move mounting points, block an access opening or change the loads at the existing connections.
Does a steel-structure CAD file include local approval?
The supplier’s CAD drawing communicates the display layout and interfaces. Local design review, any required approval and release for fabrication need an assigned party in the project scope. Ask the fabricator which signed or reviewed documents they require before cutting steel, and record who obtains them alongside the schedule for cabinet delivery.
How is front-service access reflected in the frame?
Show the path of the part being removed, including the space for tools and hands at the edge and centre of the display. Mark cable and power connections as separate access points. A frame can leave the module face clear while still covering a fastener or obstructing a component behind it.
What happens if cabinet dimensions change after the drawing?
Stop using the superseded drawing for new fabrication. Compare the revised cabinet grid, fixing positions, weight, cable routing and service paths with the last accepted set. Have the affected parties record which parts can be retained before releasing a new revision. An unchanged overall screen width does not guarantee unchanged structural interfaces.
