Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] see figure 1 , a new truss-type steel roof truss, including upper chord 1, lower chord 2, diagonal web 3, straight web 4, upper chord gusset 5, lower chord gusset 6, upper chord connecting plate 7, lower chord connecting plate 8 , Sandalwood supporting plate 9, bearing plate 10, web bar angle steel limb 11, web bar connecting plate 12.

[0017] The upper chord 1 is a downward C-shaped section composed of two unequal angle steels passing through the upper chord gusset plate 5 and the upper chord connecting plate 7. The short legs of the angle steel are located on both sides of the section; The gusset plate 6 and the lower chord connecting plate 8 form an upward C-shaped section, and the short legs of the angle steel are located on both sides of the section; the upper chord gusset plate 5 and the lower chord gusset plate 6 are connected ...

Abstract

The invention discloses a novel trussed steel roof frame, which consists of an upper chord rod, a lower chord rod, a web rod, a connection point plate and a connection plate. Section shapes of the upper chord rod, the lower chord rod and the web rod are improved, so that the material performance can be fully used; and effects of saving materials and greatly improving the anti-corrosion coating quality and the maintainability of the roof frame are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial and civil building steel structures, and relates to a truss type steel roof truss of a new structure type. Background technique [0002] There are two known truss-type steel trusses, one is a triangular roof truss with a triangular appearance, and the other is a trapezoidal roof truss with a trapezoidal appearance; the triangular roof truss is generally used for buildings with a span of less than 18 meters, and the trapezoidal roof truss is generally used for larger Long-span buildings. [0003] The known truss-type steel roof trusses consist of upper chords, lower chords, webs and gusset plates. All members are connected by unequal angle steel or equilateral angle steel with filler plates. The design theory is to ensure that the short limbs are not unstable in the plane under compression and comply with the maximum slenderness ratio in the steel structure design code. While the compression c...
