3807-BS300 Standard Bolt Truss Design for Lighting and Exhibition Structures
Introduction
This drawing archive presents the BS300 standard round tube bolt-connected aluminum truss components developed for lighting structures, exhibition frameworks and mechanical support applications.
The drawings are indexed under references 3807, 3886, 3926 and 3939, covering multiple standard lengths from 1.1m to 3.2m.
The BS300 series adopts a 300mm × 300mm square truss structure with 50mm aluminum round main tubes. The bolt-connected design provides a flexible solution for temporary structures where transportation, installation efficiency and configuration flexibility are important.
Unlike welded permanent structures, bolt-connected aluminum truss systems can be disassembled, transported and reused, making them suitable for event applications, exhibition installations and entertainment structures.
Design Overview
The BS300 round tube bolt-connected truss adopts a modular structural design.
The main components include:
50mm aluminum round tube main chords;
Aluminum diagonal braces;
Square end plates;
Bolt-connected assembly system.
Compared with fixed welded truss structures, bolt-connected truss systems provide advantages in:
Easy transportation;
Convenient storage;
Flexible installation;
Reusable structural configuration;
Customized length selection.
The 300mm × 300mm cross-section provides a balance between structural performance and portability, making it widely used for small and medium-scale lighting and exhibition structures.
The connection method is an important factor when selecting temporary structure components. Different connection systems, such as spigot connection, bolt connection and plate connection, are selected according to application requirements.
