Description

Technical Field

[0001] The utility model relates to the technical field of production of reinforced concrete prefabricated panels, in particular to a reinforced concrete prefabricated panel provided with connecting pieces. Background Art

[0002] Reinforced concrete precast panels are concrete components made in a factory environment with a flat, smooth surface and a variety of sizes. Its production process is standardized and modular, which can be completed quickly and efficiently, while saving manpower and facilitating on-site assembly. Precast panels are widely used in construction, roads, bridges, tunnels and other projects to make various structures or components, such as roofs, floors, walls, etc.

[0003] Existing reinforced concrete prefabricated panels generally do not have connectors and have poor integrity, which limits their production flexibility and ability for personalized design. Since they cannot be adjusted according to specific design requirements, their bearing capacity may be affected to a certain extent, which in turn affects the overall safety. During on-site construction, prefabricated panels without connectors need to be assembled through steel bar connections, which not only prolongs the construction period and increases labor costs, but may also have an adverse effect on construction quality. In addition, prefabricated panels without connectors require complex steel bar processing, drilling and assembly work on site, which further increases the difficulty of construction and urgently needs improvement and optimization.

[0004] How to solve the above technical problems is the subject faced by the present utility model. Utility Model Content

A T-shaped connector is fixed on one side of the short side surface of the prefabricated panel body, and a connecting groove matching the connector is opened on the other side of the short side surface of the prefabricated panel body. The utility model arranges a connector and a connecting groove on the prefabricated panel to connect the prefabricated panel into a whole, and seals and reinforces the connecting groove and the connector with concrete after assembly to improve the integrity and stability of the component, enhance its mechanical properties, improve its bearing capacity and seismic resistance, and make it more suitable for high-strength structural requirements. After the prefabricated panel is equipped with a connector, it can be directly installed, eliminating on-site processing and assembly work, and speeding up the speed of construction; the connector can ensure the accuracy and consistency of prefabricated panel production through automated production and factory operation, thereby improving construction quality and reliability.

[0007] Furthermore, a snap-in opening is provided on the snap ring, a bolt opening is provided on the upper surface of the prefabricated plate body on one side of the snap-in opening, and a bolt fixing groove is provided inside the bolt opening.

[0014] Furthermore, a plurality of evenly distributed weight-reducing holes are preset on the surface of the precast panel body, and the weight-reducing holes penetrate the surface of the precast panel body, thereby reducing the weight of the reinforced concrete precast panel, saving materials, and facilitating transportation and hoisting.

[0015] Furthermore, the number of the connecting heads and the connecting grooves is two, and the two connecting heads and the two connecting grooves are respectively located on both sides of the short side of the prefabricated board body. By setting the number of the connecting heads and the connecting grooves to two, and the two connecting heads and the two connecting grooves are respectively located on both sides of the short side of the prefabricated board body, such a layout design not only ensures a stable connection between the prefabricated boards, but also optimizes the mechanical properties of the overall structure, making it more adaptable to high-strength structural requirements and ensuring uniform force on the device.
