Novel roof truss construction structure

Abstract

The invention discloses a novel roof truss construction structure. The novel roof truss construction structure comprises a first truss core, wherein a first connecting rod is welded inside the first truss core, two sides of the first connecting rod are respectively connected with a plurality of upper chord members and lower chord members in a rotating manner, the upper chord member is located above the lower chord member, a web member is arranged between the upper chord member and the lower chord member, one end, away from the first connecting rod, of the upper chord member is connected with afixed block in a welding manner, a fixed rod is welded on a position, away from the first truss core, of the bottom of the lower chord member, and the bottom of the fixed rod is connected with a damping apparatus in a rotating manner. By adopting the novel roof truss construction structure, the born pressure can be uniformly scattered, when in breaking, the pressure can be alleviated by virtue ofbending, the safety potential hazard can be reduced, when in impaction and shaking, the shaking can be alleviated, the damage of the junction can be prevented, the pressure is uniformly scattered tothe ground by virtue of the base, the tilting can be prevented, when the height is adjusted, the height of local areas can be separately adjusted, and the construction requirement can be met.

Description

technical field [0001] The invention relates to the field of roof trusses, in particular to a novel roof truss construction structure. Background technique [0002] A truss is a geometrically invariant structure composed of a triangular frame composed of straight rods. The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials, and reduce structural weight. According to the axis of the truss members and the distribution of the external force, the trusses can be divided into plane trusses and space trusses. Spatial structures such as roof trusses or bridges are composed of a series of parallel planar trusses. [0003] Existing roof truss construction structures usually use cuboids composed of metal rods or wooden rods to disperse pressure and hinge rotation connections between metal rods: most of this type of roof truss construction structures are of average stability and cannot evenly distr...

Problems solved by technology

[0003] Existing roof truss construction structures usually use cuboids composed of metal rods or wooden rods to disperse pressure and hinge rotation connections between metal rods: most of this type of roof truss construction structures are of average stability and cannot evenly distribute pressure, and some support rods When it breaks, the broken connecting rod hangs in the air, causing pressure and potential safety hazards. Since multiple connections are welded for stability, the connections are easily damaged in the face of impact and vibration. When adjusting the height, it can only be mobilized as a whole, and the pressure passes through the support. When the legs reach the ground, they do not spread evenly and tend to skew
