Fabricated floor slab wet connection knot and connection method

Abstract

The invention discloses a fabricated floor slab wet connection knot and a connection method. The knot comprises a I-shaped beam, a first prefabricated floor slab and a second prefabricated floor slab;a plurality of studs are evenly fixed on the I-shaped beam; the first prefabricated floor slab and the second prefabricated floor slab are correspondingly located at two sides of the studs and form amounting groove; the first prefabricated floor slab is provided with a first groove; the first groove is internally provided with a plurality of first protruding steel bars; a first distributed steelbar is fixed on the plurality of protruding steel bars; the second prefabricated floor slab is provided with a second groove; the second groove is internally provided with a plurality of second protruding steel bars; a second distributed steel bar is fixed on the plurality of second protruding steel bars; corresponding second protruding steel bars and the first protruding steel bars are all interconnected and fixed through additional steel bars, and a plurality of U-shaped shear reinforcement bars are arranged at intervals in the mounting groove; and concrete is poured in the mounting groove,the first groove and the second groove.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, and more specifically relates to a wet connection node and connection method of a prefabricated floor slab. Background technique [0002] Today, with the continuous development of urban architecture, the industrialization of architecture has gradually become a new development trend of architecture. The so-called construction industrialization refers to the use of advanced industrial technology, production methods, management methods, etc. to replace traditional building construction methods. Industrialized production methods are adopted, and prefabricated assembly parts are mostly used to minimize the disadvantages of scattered construction, low-efficiency operations, high labor costs, and long construction periods in traditional building construction. [0003] With the emergence of prefabricated buildings, the industrialization of the construction industry has been realized, wit...

Problems solved by technology

[0004] However, the common practice at this stage is to use laminated floor slabs, but laminated floor slabs also have disadvantages such as slow construction speed and complicated on-site installation and construction.

Or concrete is poured between adjacent prefabricated slabs, but studies have shown that concrete at the joints of laminated floors usually cracks under the action of temperature and volume shrinkage
