Description
Technical Field
[0001] The utility model relates to the technical field of prefabricated composite panels, in particular to prefabricated composite panels for assembled buildings. Background Art
[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. In prefabricated buildings, composite panels are the most commonly used prefabricated components in prefabricated buildings, and their construction quality has an important impact on the entire project. Composite panels are assembled integral floor slabs composed of prefabricated composite panels and cast-in-place reinforced concrete layers. However, compared with the tightness of the connection between the prefabricated composite panels and the cast-in-place concrete on them, the tightness of the connection between adjacent prefabricated composite panels needs more attention, because the tightness of the connection between adjacent prefabricated composite panels is worse, and it is easy to crack due to stress and vibration.
[0003] In response to the above problems, “A prefabricated composite board for assembled buildings” with Chinese publication number CN218843488U, by arranging end protrusions and end grooves at the front and rear ends of the concrete structure layer, and arranging side protrusions and side grooves on both sides of the concrete structure layer, can make the contact surface of two adjacent prefabricated composite boards larger when connected, thereby making the bonding force between them stronger, and it is not easy for cracks to occur between the two adjacent prefabricated composite boards during use, which affects their use, and by arranging a steel mesh in the concrete structure layer and extending outward on all four sides, the connection between the two adjacent prefabricated composite boards is made stronger.
[0004] However, this type of prefabricated composite slab still has certain defects when in use. For example, the steel bars of this type of prefabricated composite slab are directly exposed. During transportation or handling, the exposed ends of the steel bars may cause accidental injuries such as scratches to construction workers. In addition, although the bent connection seams of this type of prefabricated composite slab increase the contact area, they put forward higher requirements on the pouring and vibration of cast-in-place concrete. Improper operation may lead to insufficient concrete filling, forming voids, affecting the integrity and durability of the structure. Utility Model Content
