Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] see Figure 1~5 , a precast concrete ring beam-floor connection structure based on PBL connection, including a transverse ring beam 1, a longitudinal ring beam 2, an inner ring beam 3, a prefabricated floor 4 and an upper wall 5; the transverse ring beam 1 and the longitudinal ring beam 2. The inner side of the longitudinal ring beam 2 is provided with a parallel inner ring beam 3, and the longitudinal ring beam 2 is provided with a ring beam reserved f...

The invention discloses a prefabricated concrete ring beam-floor connection structure based on PBL connection and an installation method. The structure comprises a transverse ring beam, a longitudinal ring beam, an inner ring beam, a prefabricated floor, an upper-layer wall, ring beam reserved floor supporting surfaces, a ring beam-upper shear wall pre-embedded part, a ring beam-lower shear wall pre-embedded part, a transverse-longitudinal ring beam connecting pre-embedded part, a prefabricated floor hand hole, and a floor connecting rabbet. The prefabricated concrete ring beam-floor connection structure based on PBL connection has the beneficial effects that on-site wet operation is abandoned, and the advantages of saving resources, protecting the environment and reducing pollution of a prefabricated building technology are exerted to the maximum extent. According to the installation method, the floor supporting surfaces is reserved on the ring beams, after the ring beams are installed, a floor is supported by the ring beams and can be directly erected on the ring beams, and the bottom of the floor does not need to be supported in installation. The adjacent floors adopt a tongue-and-groove method to ensure that joints between the floors are closely spliced. Adjacent floors are connected by the rabbet, so that close splicing between the joints of the floors is ensured. Compared with a steel structure house commonly adopted by middle and low-rise buildings, the connection structure has better durability and comfort.
Description
technical field [0001] The invention relates to a ring beam-floor connection structure, in particular to a prefabricated concrete ring beam-floor connection structure and an installation method based on PBL connection, and belongs to the technical field of construction engineering applications. Background technique [0002] PBL connection is a kind of shear connector embedded in concrete. It has been used in the field of bridges, and it is used for the first time in prefabricated components of house construction. The PBL connection has large bearing capacity, good ductility, easy and quick installation, and has the property of secondary use after disassembly, which is friendly to the environment. Mass production costs are lower. [0003] The connection between the ring beam and the floor slab in the existing prefabricated concrete building still retains the method of pouring concrete at the connection point, which does not have the function of turnover. The existing steel ...
