Embodiment Construction

[0044] Figure 1 schematically shows a bay of a building for pouring concrete floors and having suspended trusses mounted on columns. The suspended truss 2 has two main girders 4 extending between and supported by columns 12 of the building to which they are mechanically secured by column jacks 9 mounted on the columns. A bay 11 of a building is usually the space between columns 12 . A number of beams 6 of the composite structure are connected to the main beam 4 . These beams are generally perpendicular to the main beam 4 . Rail beams 8 are attached to the upper surfaces of the beams 6 and support the plywood shelving 14 . Once the reinforced concrete floor 10 has been poured and partially hardened so that it can support its own weight, the suspended trusses can be lowered on the column jacks 9 and removed from the bay to be placed in the Between the columns of the next floor or adjacent bay.

Abstract

An assembled structural beam according to the present invention comprises a top chord and a bottom chord mechanically connected by series of diagonal connecting members. The top chord includes, on an upper surface, a longitudinally extending bolt slot. The bottom chord includes, on a bottom surface, a longitudinally extending bolt slot. Each of the chords have two opposed side surfaces with a shallow channel recess in one side and extending the length of the chord, with a complementary projection on the opposite side and extending the length of the chord sized for receipt in the shallow channel recess. Each chord is an extruded component and includes a securing flange which cooperates with the diagonal connecting members to secure the top chord to the bottom chord. The structural beam is particularly useful in flying forms for concrete forming.

Description

technical field [0001] This invention relates to a truss system for use in the construction industry and, in particular, to a column-suspended truss system for forming concrete floors. Background technique [0002] Trusses in suspended form are used to form the concrete floor slabs of the multi-story structure. During the rapid construction period, some truss systems in the form of suspension convey the poured concrete directly to the lower slab, which has not yet fully hardened. For this reason, rebracing of the underlying concrete slab may be necessary in order to transfer loads to the fully hardened slab. The restoring takes extra time and also limits access to some of the lower heights that have hardened effectively. [0003] In order to overcome the above-mentioned problems, it is known to use columns of a truss system mounted in suspended form, conveying the concrete to the column opposite the floor below. The truss system with the columns installed allows full acce...
