AI Technical Summary
When existing steel bar trusses come into contact with pressed steel plates or concrete, the contact area is small, easy to deweld or cannot be well poured with concrete.
A plate belt is provided on the lower side of the steel bar truss and is fixedly connected with the bending feet of the steel bar truss to form a steel bar truss with the steel bar. After the steel bar truss is combined with fiber cement flat plates or fine stone concrete, a mold-free steel bar truss floor bearing plate or laminated plate is formed.
By increasing the contact area between the steel bar truss and the base plate increases, the strength of the mold-free floor bearing plate or laminated plate is improved, and the punching of the plate strip is conducive to the combination with concrete or fiber cement plates.
