Problems solved by technology
There are some deficiencies in the practice of laminated floor slabs: (1) There are many wet operations of cast-in-place concrete, and the overall assembly rate is low; (2) The thickness of the prefabricated part is small, which makes the prefabricated part vulnerable to damage during transportation and hoisting, and even affects Carrying capacity

The invention provides a dry connecting structure for an assembled-type prefabricated beam and a prefabricated floor slab. The dry connecting structure comprises a prefabricated T-shaped beam plate and the prefabricated floor slab, the prefabricated T-shaped beam plate comprises first rebars and a first embedded steel plate welded on the first rebars, a plurality of first openings are formed in the first embedded steel plate, the first T-shaped beam plate is provided with first reserved holes corresponding to the first openings, and a first grout hole is formed in each first reserved hole; the prefabricated floor slab comprises second rebars and a second embedded steel plate welded on the second rebars, the first embedded steel plate and the second embedded steel plate are docked, the second embedded steel plate is provided with a plurality of second openings, the prefabricated floor slab is provided with second reserved holes corresponding to the second openings, a second grout hole is formed in each second reserved hole, and each first reserved hole and the second reserved hole communicated with the same form an independent grouting area which forms a grouting section after grouting. By the dry connecting structure, connecting reliability is improved, assembly efficiency is improved, and wet operation is reduced.
Description
technical field [0001] The invention relates to the construction field, in particular to a dry connection structure between an assembled prefabricated beam and a prefabricated floor. Background technique [0002] At present, prefabricated laminated floors are still the main method in prefabricated buildings. The practice of prefabricated laminated floors is composed of prefabricated parts and cast-in-place parts. Among them, the prefabricated parts are mostly thin plates, which are processed in the factory and then Transported to the construction site for hoisting, and used as a formwork for the cast-in-place part. There are some deficiencies in the practice of laminated floor slabs: (1) There are many wet operations of cast-in-place concrete, and the overall assembly rate is low; (2) The thickness of the prefabricated part is small, which makes the prefabricated part vulnerable to damage during transportation and hoisting, and even affects Carrying capacity.
