Abstract

The invention discloses a permanent formwork, which comprises an ultra-high performance concrete layer. The ultra-high performance concrete layer comprises a bottom plate and side plates arranged on the bottom plate. Grooves are uniformly distributed on the inner surface of the ultra-high performance concrete layer. In addition, the invention discloses a reinforced concrete beam structure composedof the permanent formwork and a manufacturing method. The permanent formwork works together with post-poured ordinary concrete, and good force performance is achieved. Because there are shear bonds distributed between the ultra-high performance concrete layer and the post-poured ordinary concrete, the bonding between the two materials is increased, and the shear capacity of the beam is greatly improved.

Description

technical field [0001] The invention relates to the field of civil engineering structure reinforcement, and relates to a permanent formwork and a reinforced concrete beam structure and a manufacturing method thereof. Background technique [0002] Concrete engineering is divided into two categories: cast-in-situ concrete structure engineering and precast concrete structure assembly engineering, and concrete prefabricated components are divided into factory prefabrication and on-site prefabrication. Driven by the improvement of the seismic performance of engineering structures and the continuous improvement of cast-in-place concrete engineering technology, cast-in-place concrete has become the main type of concrete engineering today. The construction of cast-in-place concrete structure engineering is divided into three sub-projects: formwork engineering, steel reinforcement engineering and concrete pouring engineering. The construction sequence of formwork and reinforcement v...
