21 cze 2023 · The Mono Truss is configurable in a range of sizes with typical spans between 16’-40’ (4.9-12.2 m) and overall heights of 5’4”-40’ (1.63-12.2 m). The thickness of wood trusses is commonly 1.5”, 3”, or 4.5” (3.8, 7.6, 11.4 cm). Trusses have a pitch ratio typically between 1:1 to 1:6.
An advantage of the truss design for roofs is that ducts and pipes that are required for operation of the buildings services can be installed through the truss web. 1.4.2 General geometry In order to get a good structural performance, the ratio of span to truss depth should be chosen in the range 10 to 15.
At Minera Roof Trusses we often use mono trusses in combination with raised tie roofs and lattice trusses as shown in the image below. The lattice trusses will span along the apex between the raised tie trusses.
Roof Truss Span Tables. Alpine truss designs are engineered to meet specific span, configuration and load conditions. The shapes and spans shown here represent only a fraction of the millions of designs produced by Alpine engineers. Total load(PSF) Duration factor. Live load(PSF) Roof type.
Queen post truss details: Unlike the king post, the queen post truss has two vertical posts, providing additional support for wider roof spans. 3. Scissor and Mono Pitch Roof Truss Details. Scissor trusses create a vaulted ceiling effect, while mono-pitch trusses are used for sloped roofs.
This document provides roof truss span tables for different roof configurations including common, mono, scissors, and flat roofs. It lists the top and bottom chord sizes and maximum span lengths in feet for various roof pitches, truss depths, and load conditions.
Hipped roofs constructed with trussed rafters typically require a series of diminishing mono-pitched trusses supported by a girder truss. The bearing of mono-pitched trusses into shoes should be in accordance with Table 1, unless designed by an engineer in accordance with Technical Requirement R5.
