Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled prestressed support-free structure in a hydraulic environment. Background Art

[0002] Compared with reinforced concrete solid slabs, reinforced concrete hollow slabs have lower cost, less materials, lighter weight and better sound insulation. The construction method of reinforced concrete hollow slabs in the prior art mainly involves first setting up the bottom formwork of the hollow slab, tying steel bars, placing side formworks, and then placing a hollow mold box on the bottom formwork, pouring concrete in the cavity enclosed by the bottom formwork and the side formworks, and after the concrete reaches a certain strength, removing the side formworks and bottom formworks, and then brushing mortar on the bottom of the slab to form an integral hollow slab.

[0003] The connection of UHPC cast-in-place concrete is connected by truss reinforcement. When the steel strands in the UHPC base plate are tensioned by prestressing, the presence of truss reinforcement will share part of the prestress, resulting in the loss of prestress in the UHPC base plate. The compressive capacity of concrete in the prestressed structure is enhanced due to the stress of the prestressed reinforcement, and the tension of the structure is mainly borne by the prestressed reinforcement;

[0004] However, when the existing UHPC ribbed composite plates are connected to the columns, they are only erected on the columns in a single manner, lacking connection with the columns, and the UHPC ribbed composite plates installed on the columns are not stable enough, which may cause safety hazards. Therefore, based on the above-mentioned problems, an assembled prestressed support-free structure for hydraulic environment is introduced. Utility Model Content
