Embodiment Construction

[0040] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0041] like figure 1 As shown, a high and low web truss beam according to an embodiment of the present invention includes a high web truss beam 1, a low web truss beam 2, an L-shaped connector group 3, a steel strip 4, a hexagonal bolt 5, and a self-tapping screw 6. Among them, the high-web truss beam 1 and the low-web truss beam 2 are butt-connected through the connector group 3, the steel strip 4, the hexagonal bolt 5 and the self-tapping screw 6.

[0042] like figure 2 , Figure 4 As shown, the high-web bar truss beam 1 includes a first U-shaped steel upper chord 11, a first C-shaped steel oblique web bar 12, a first C-shaped steel straight web bar-13, a C-shaped steel second straight web bar-14, a first A U-shaped steel bottom chord 15. Fur...

Abstract

The invention discloses high and low web member truss girders based on fabricated type cold-formed thin-wall section steel. The truss girders comprise a high web member truss girder, a low web membertruss girder, a connecting piece group and steel belts. The high web member truss girder and the low web member truss girder comprise U-shaped section steel upper chords, C-shaped steel diagonal web members, C-shaped section steel first vertical web members, C-shaped section steel second vertical web members and U-shaped section steel lower chords. The connecting piece group comprises an L-shapedfirst connecting piece, an L-shaped second connecting piece and an L-shaped third connecting piece, wherein the L-shaped second connecting piece is separately used with the L-shaped first connecting piece and the L-shaped third connecting piece, and the L-shaped first connecting piece, the L-shaped second connecting piece and the L-shaped third connecting piece are fixedly connected through boltsand self-tapping screws. The joint U-shaped section steel lower chords and the C-shaped section steel second vertical web members are sleeved with the steel belts and fixedly connected through screws.The invention firstly discloses a solution method for the docking arrangement of the high web member truss girder and the low web member truss girder, the requirement of floor local board descendingis realized in the condition of not adding lower layer stand columns, a force transferring route is clear, and the mechanical property at the joint is good.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a high and low web truss beam based on prefabricated cold-formed thin-walled steel. Background technique [0002] Due to the different functions of each room in the building and residence, different floor and floor decoration materials are used accordingly, which will also cause local slab drop. Generally speaking, the overall lowering slab can be used to deal with the lowering slab, that is, all the beams and slabs of the structure are lowered to the required elevation as a whole, and the rest is leveled through the surface layer. This approach not only reduces the clear height of the lower room, but also increases the load borne by the floor. The other is a local lowering slab that lowers the beam slab at the desired lowering slab to the required level. Although the construction and stress of this method become complicated, it does not increase the load and do...
