To analyse the Roof Truss Forms

Description

Before we build or design a Roof Truss. we may have to analysis the Truss forms and following we gonna analyze from different aspects :From the aspects of mechanics and analysis of truss shape bending moment diagram is similar to that of a simply supported beam, the bottom chord axial force distribution is uniform, diagonal axial force is small, the materials the most provinces; Analysis from the material and manufacturing, wood made triangle truss, steel truss of trapezoid or parallel chord shape, reinforced concrete and prestressed concrete truss as polygon or trapezoid is advisable.Truss the ratio of height and span, usually use 1/6 ~ 1/12, have specific provisions in the design manual and specification. Truss using range is very wide,should be considered when choosing truss form the purpose of the truss, materials and supporting method, construction conditions, the principle of choosing the best form is under the premise that meets the requirement, to materials and labor used in the manufacture and installation to the minimum. Roof Truss may consist of aluminum truss, steel truss open space truss, insert truss, the cue rack, tooth column for truss.1, Aluminum truss, light and flexible, safe and reliable, it can combinate freely, dismounting conveniently, also can be divided into three tube, four tube aluminum trusses,aluminum tube, aluminum truss welding truss;2, Steel truss, tubes and tube, triangular and quadrilateral perfect combination, stiffness big, large span, modelling grand;3, tooth bar truss: beautiful appearance, flexible structure, qualitative light, ever-changing modelling with colourful lamp, make whole booth more gorgeous, bright;4, the ball clubs: 18 hole section aluminum ball, with a diameter of 22 mm and 30 mm of two kinds of aluminum alloy cue connection, including 30 clubs notches can be connected to metro batong exhibition;5, board: board with 150, 200 mm wide two specifications, the shape of circle, triangle and so on, beautiful appearance, light and flexible, can make the booth have transparent effect, strong artistic;6, aluminum soldering truss: light texture, novel, beautiful shape, can be used for all sorts of modelling of booth and use in Roof Trusses Systems;7, butterfly truss: can be widely used in various industry exhibition, tear open outfit, easy to transport;8, LH series: straight tube with inclined tube perfect collocation, can be widely used in all sorts of modelling of the booth, all packaged structure, easy installation and disassembly, can realize long-span connection. 987XMLTR 130521
