Steel bar truss floor support plate and system

Abstract

The invention provides a steel bar truss floor support plate and a production method. The steel bar truss floor support plate is characterized in that the steel bar truss floor support plate comprises a truss and a bottom plate, and the truss is fixedly arranged on the bottom plate; the truss comprises a plurality of truss units and connecting rod reinforcing steel bars used for connecting the truss units, each truss unit comprises an upper chord reinforcing steel bar arranged on a first reference plane, a first lower chord reinforcing steel bar and a second lower chord reinforcing steel bar arranged on a second reference plane, a first web member reinforcing steel bar arranged on a third reference plane, and a second web member reinforcing steel bar arranged on a fourth reference plane; and the first reference plane, the second reference plane, the third reference plane and the fourth reference plane are determined according to a preset optimization model. The steel bar truss floor support plate can be machined and manufactured in advance before leaving a factory, the field installation workload is reduced, and the field installation efficiency of the steel bar truss floor support plate is improved; and meanwhile, the anti-seismic performance is high, and the quality of a corresponding building is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a reinforced truss floor deck and a system. Background technique [0002] The steel truss floor deck is a kind of unsupported pressure-type composite floor deck, including the steel truss and the bottom plate; the steel truss is finalized and processed in the background processing plant, and the on-site construction needs to fix the bottom plate on the beam with studs or welding , then place steel trusses for binding, and pour concrete after the acceptance of the steel truss floor deck. However, in the process of installing the reinforced truss floor deck on site, specifically in the installation process of the fasteners at the connection position, multiple procedures are required to complete the installation, and the construction process is relatively cumbersome. , needs to be aligned, positioned, fixed and tied, especially during the installation process, which usually requires syn...

Problems solved by technology

However, in the process of installing the reinforced truss floor deck on site, specifically in the installation process of the fasteners at the connection position, multiple procedures are required to complete the installation, and the construction process is relatively cumbersome. , needs to be aligned, positioned, fixed and tied, especially during the installation process, which usually requires the simultaneous installation of the bottom plate, steel trusses and fasteners, resulting in inconvenient construction on site, laborious installation process, and low installation efficiency

Therefore, the existing floor deck has the problem of low on-site installation efficiency
