Hanging truss
The hanging structure is a structure in timber , steel or reinforced concrete construction . The loaded bundle beam ( truss beam ) is hung on hanging posts . The hanging posts absorb the load from the collar beam as tensile force and transfer this to the struts at the upper node as compressive forces or, in the case of the double hanging structure, in the tie bar and strut . The struts in turn support the compressive force from the collar beams (see Langerscher beams ) or into the supports .
In contrast, a truss works without hanging posts and directs the pressure forces of the struts below the horizontal beam directly into the supports. This also applies to suspended trusses, however, in which the struts run partly below and partly above the collar beam. This means that it can be hung from a hanging post, just like with the hanging structure.
Roof trusses are sometimes designed as hanging trusses and then support the ceiling of the floor below. In this way, a large, column-free space can be created there.
In the case of a hanging structure, the struts are often connected to the hanging post with a double offset and the clamping bar with a front offset at the top.
