Description

Technical Field

[0001] This utility model relates to the field of double-T slab technology, specifically a prestressed double-T slab for floor slabs. Background Technology

[0002] Double-T slabs are precast reinforced concrete load-bearing components that combine slab and beam structures. They consist of a wide panel and two narrow, tall ribs. The panel provides lateral load-bearing support, while the longitudinally positioned ribs provide compression support. In construction, double-T slabs can be directly placed on frames, beams, or load-bearing walls, or used as floor or roof structures.

[0003] Current double-T panels use a fixed structural design, which does not allow for adjustment of the width of the top panel, thus limiting their applicability. Furthermore, adjacent double-T panels cannot be assembled together, resulting in limited lateral stability. Double-T panels are generally designed as a single unit, making them heavy and inconvenient to produce, transport, and hoist, which can easily lead to safety accidents.

[0004] The inability to adjust the width of the top panel limits its applicability and makes it inconvenient to use; the inability to assemble the double T-panels together results in limited lateral stability, leading to gaps at the joints and poor overall integrity and load-bearing capacity when the double T-panels are assembled continuously; the large weight makes production, transportation and hoisting inconvenient, easily causing safety accidents, posing a certain threat to the production environment and making it difficult to guarantee the personal safety of workers.
