Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] as attached figure 1 , 2 , 4, 5, and 7, the precast concrete ultra-thin two-way loaded reinforced truss laminated floor is composed of beams, studs, temporary supports, connecting plates, triangular steel trusses, prefabricated short bars, and precast concrete slabs ; The basic unit of the precast concrete ultra-thin two-way stressed assembled reinforced truss laminated floor includes a transverse I-shaped beam (1), a longitudinal I-shaped beam (2), a temporary support (4) and a prefabricated concrete slab layer (6).

[0031] as attached figure 1 As shown, the laminated floor beam includes a transverse I-shaped section beam (1) and a longitudinal I-shaped section beam (2). The upper and lower ends of the connecting plate (5) are welded on the transverse I-shaped cross-section beam (1). The studs (10) are welded on the upper surface of the upper flange of ...

Abstract

The invention discloses a prefabricated concrete ultra-thin type two-way stress fabricated steel bar truss composite floor slab, and belongs to the technical field of structural engineering. The basiccomposition of a composite beam-slab structure comprises shape steel beams, three-dimensional truss temporary supports, connecting plates, triangular reinforcing steel bar trusses, prefabricated short bars and prefabricated concrete slabs, wherein the shape steel beams are welded to the connecting plates, and the prefabricated short bars, the reinforcing steel bar trusses and the prefabricated floor slab are poured into a whole. The beams, the temporary supports and precast concrete floor slabs are hoisted in place and connected by bolts, reinforcing steel bars are paved in a penetrating mode, and the beams, the temporary supports and precast concrete floor slabs are poured with remaining concrete. The prefabricated concrete ultra-thin type two-way stress fabricated steel bar truss composite floor slab with temporary supports is used, the problem of integrity of the floor slab is solved, the reliability of the floor slab in the construction stage is guaranteed, a post-pouring strip ofthe fabricated floor slab is avoided, the field work efficiency is improved, the thickness of the prefabricated concrete slab is reduced, the weight of the hoisting is reduced, and the fabricated accuracy is improved.

Description

technical field [0001] The invention relates to a prefabricated concrete ultra-thin two-way force-bearing assembled steel bar truss laminated floor slab, which belongs to the technical field of structural engineering. Background technique [0002] Prefabricated buildings are the focus of development in my country's construction industry for a period of time in the future, and the innovation of industrialized prefabricated structural systems is imperative. The prefabricated structural system refers to the building produced by making housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. A large number of building parts are produced and processed by the workshop, a large number of assembly operations on site, standardization of design and informatization of management meet the requirements of green buildings. It is characterized by light building weight, energy savi...
