Problems solved by technology

[0003] At present, the main components of the truss: the chord and the web are formed through fasteners, bolts or welding to realize the formation of the entire truss structure. In order to adapt to different working environments, some truss structures with adjustable chords have also appeared. The previous truss structure has not changed much, and when adjusting the length of the chord, the position of the web must be re-installed and adjusted, which is more troublesome and increases the cost of the process and labor

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0018] Such as figure 1 As shown, the parallel chord plane truss with variable node positions and lengths of diagonal webs includes upper chord 2, lower chord 8, straight web 6 and diagonal web connecting upper chord 2 and lower chord 8, upper chord 2 and lower chord A connecting piece is provided between the rod 8 and the straight web bar 6 and the diagonal web bar. The connecting piece includes a sleeve 1 coaxially connected with the upper and lower chord bars 2, 8 and a single lug detachably connected with the web bar, and the sleeve 1 is provided with positioning bolt holes 11 and positioning bolts 12 in the radial direction (see image 3 ), there are three single lugs arranged along the axial direction of the sleeve 1, one of which is a straight lug 4 perpendicular to the axial direction of the sleeve 1, and the straight lug 4 is connected wit...

Abstract

The invention discloses a plane truss for parallel chords, which is featured in that the node position and length of diagonal web members are changeable and falls into the field of structural members. The detachable connection with chords through connectors and the telescopic mechanism of diagonal web members achieve the effect that the node position and length of the diagonal web members are changeable, thus improving the applicability of the truss in different working places.

Description

technical field [0001] The invention belongs to the field of structural components, and in particular relates to a parallel chord plane truss with variable node positions and lengths of diagonal web members. Background technique [0002] A truss is a planar or spatial structure composed of straight rods, generally with triangular elements. Under load, the truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save material, reduce self-weight and increase rigidity, and is suitable for large-span load-bearing. Structures and tall structures such as roof trusses, bridges, transmission line towers, satellite launch towers, hydraulic gates, crane frames, etc. [0003] At present, the main components of the truss: the chord and the web are formed through fasteners, bolts or welding to realize the formation of the entire truss structure. In order to adapt to different working environments, so...
