Problems solved by technology

[0004] However, the bottom surface of the existing connecting fasteners often cannot be closely attached to the upper surface of the bottom slab. After the concrete floor is poured, hollowing will occur, resulting in the disconnection of the concrete at the bottom of the connecting fastener, which seriously affects the reinforced truss floor deck. the quality of
And when using the above-mentioned reinforced truss floor slab for concrete floor pouring, after the concrete floor slab is poured, the bond strength between the galvanized sheet or wood floor and the mortar cannot meet the design requirements, so the floor needs to be removed to Make the concrete floor meet the design and use requirements
However, the removal of the bottom plate requires a lot of manpower and material resources, and it will also prolong the construction time, resulting in an increase in construction costs.

The steel bar truss floor support plate comprises a bottom plate and a steel bar truss arranged on the bottom plate, further comprises a reinforcing reinforcement assembly, the reinforcing bar assembly comprises reinforcing bars on the bottom plate, first upper chord steel bars arranged on the reinforcing bars and first lower chord steel bars arranged on the reinforcing bars, the steel bar truss comprises web member steel bars arranged on the bottom plate, second upper chord steel bars arranged on the web member steel bars and second lower chord steel bars arranged on the web member steel bars.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a reinforced truss floor deck without dismantling the bottom form. Background technique [0002] Reinforced truss floor decks are more and more popular in the market because of their advantages such as standardization, factory production, stable quality, uniform distribution of steel bars and accurate dimensions. [0003] In the prior art, the reinforced truss floor deck generally includes a base plate made of galvanized sheet or wood and a steel truss connected to one side of the base plate. Generally, steel bar trusses are assembled and fixed on the base plate by connecting fasteners. [0004] However, the bottom surface of the existing connecting fasteners is often not in close contact with the upper surface of the bottom slab. After the concrete floor is poured, hollowing will occur, resulting in the disconnection of the concrete at the bottom of th...
