Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete floor and roof panels, in particular to a novel assembled reinforced concrete floor and roof panel structure. Background Art

[0002] At present, prefabricated floor and roof panels are widely used in buildings. These panels are prefabricated in the prefabrication yard, installed and connected on the construction site, and finally form a whole floor and roof panel. In the prefabricated frame structure, the connection between floor and roof panels is not only used to fix multiple panels, but also plays a role in load transfer. Therefore, a reasonable connection method is the key to ensure the smooth construction of the floor.

[0003] However, existing prefabricated floor panels have some problems in the connection process, including insufficient connection strength and unstable connection. In addition, the structure of the prefabricated floor panels is complex, the prefabrication process is inconvenient, and the installation process is cumbersome, which affects the construction efficiency.

[0004] Based on this, those skilled in the art have proposed a new type of assembled reinforced concrete floor and roof panel structure. Utility Model Content

[0005] The utility model discloses a novel assembled reinforced concrete floor and roof panel structure, aiming to solve the technical problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A novel assembled reinforced concrete floor panel structure comprises a prefabricated panel, one side of which is provided with serrated grooves at equal intervals, the interior of the serrated grooves is provided with through holes at equal intervals, the interiors of the through holes are all fixedly connected with in-panel connecting steel bars, an I-beam is arranged between the bottoms of two prefabricated panels, the top of the I-beam is fixedly connected with a connecting steel plate, the in-panel connecting steel bars all penetrate to the outside of the connecting steel plate, and bolts are threadedly connected to the outside of the in-panel connecting steel bars and the outside of the connecting steel plate.

[0008] In a preferred solution, the two tooth-shaped grooves are combined to form a post-casting section, and the size of the post-casting section is smaller than the width of the I-beam.

[0009] In a preferred solution, a shear key is fixedly provided on the top of the I-beam, and the shear key is used to enhance the connection strength between the prefabricated panel and the I-beam.

[0010] In a preferred solution, the surface of the prefabricated panel is also covered with a waterproof coating to enhance its waterproof performance.

[0011] In a preferred solution, the connecting steel bars in the plate are made of high-strength steel bars to improve the bearing capacity of the entire structure.

[0012] The utility model provides a novel assembled reinforced concrete floor panel structure with the following advantages:

[0013] The utility model connects the connecting steel plate and the connecting steel bars in the plate by bolts, has a simple structure, a stable connection, and is convenient to operate, thus reducing the construction cost of the reinforced concrete roof panel structure.
