Abstract

The invention discloses a full-fabricated floor slab assembled-type steel-concrete combined floor. The floor comprises an H-shaped steel beam and floor slabs which are disposed on the beam. One or more rows of connection studs or other connectors are disposed on the H-shaped steel beam; the two adjacent floor slabs in the steel beam-floor slab connection position are placed on the two sides of theupper flange of the steel beam; the sections, in the joint connection position on the beam, of the floor slabs are in a step shape; V-shaped notches are formed in the lower portions of the steps in the spliced joint connection positions of the floor slabs; shear reinforcements are put in the notches, in the two sides of the spliced joints, of the floor slabs; reinforcements on the upper portionsof the steps in the spliced joint connection positions of the floor slabs extend out, and lap joint reinforcements are placed to be connected with the extend-out reinforcements of the floor slabs on the two sides of the spliced joints; and UHPC or ECC concrete materials fill in the space between the floor slabs on the two sides of the spliced joints and the steel beam. According to the floor, thestud connectors, the V-shaped notches in the floor slabs, the shear reinforcements, the lap joint reinforcement structure and the post-cast UHPC or ECC concrete materials are skillfully utilized, andreliable connection between the floor slabs and the steel beam is formed.

Description

Technical field

[0001] The invention relates to the field of construction, in particular to a fully prefabricated floor slab assembly type steel-concrete combined floor. Background technique

[0002] Steel structure buildings have the unique advantages of being environmentally friendly, recyclable, and good seismic performance, and have outstanding features such as green buildings and industrialization during their full life cycle. Fabricated steel structure buildings will have great development prospects. Residential buildings account for a large proportion of the total construction. At present, steel structure houses in my country account for less than 1%. From the perspective of breaking through the bottleneck of the development of prefabricated steel structures, housing is one of the most important parts of the incremental market.

[0003] The traditional steel-in-situ concrete floor slab has good mechanical performance and economy, but the cast-in-situ floor slab is faced wit...
