Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a bridge UHPC concrete component. Background Technique

[0002] In recent years, precast concrete reinforced steel truss slabs have been widely used in the construction industry. This product can reduce the operation steps, the usage of construction forms and scaffolds during the construction process, reduce labor consumption, lower the construction difficulty, and improve the construction efficiency.

[0003] The existing closely assembled composite slabs are mainly composed of ordinary concrete and prestressed steel bars. Its function is to serve as a structural bottom slab to provide a formwork support for the cast-in-place concrete, so as to facilitate construction and eliminate form removal, etc. However, the composite slab made of ordinary concrete and prestressed steel bars is relatively thick, with a large self-weight and poor flexural and crack resistance performance, resulting in a low cost performance. In addition, the connection strength between the closely assembled composite slabs and between the slab beams is insufficient, and the connection is relatively inconvenient. Therefore, a bridge UHPC concrete component is introduced to solve the above-mentioned problems. Content of the Utility Model
