Abstract

The invention relates to concrete beams and columns and discloses a carbon fiber-polyurea double-constraint fiber reinforced concrete beam and column structure based on a trunk structure bionic designconcept. The beam and column structure comprises a fiber reinforced concrete core, a bonding layer, a polyurea middle layer, an impregnating resin layer and a carbon fiber outer layer from inside tooutside in sequence. The carbon fiber outer layer and the polyurea middle layer constrain the inside fiber reinforced concrete core structure, thereby jointly forming a beam and column strengthened structure. The fiber reinforced concrete core and the polyurea middle layer are integrated through the bonding layer, and the carbon fiber outer layer is bonded to the outside of the polyurea middle layer through the impregnating resin layer. According to the structure, a bionic trunk structure is adopted for strengthening and optimizing the concrete structure, compared with a traditional steel-concrete combined structure, a C-P-C combined component designed based on the characteristics of wooden substrate, forming layer and active phloem of the trunk structure can derive diversified mechanicalperformance and durability.

Description

technical field

[0001] The invention relates to concrete beams and columns, in particular to a "carbon fiber-polyurea" double-constrained fiber concrete (C-P-C) beam-column structure based on the idea of ​​tree trunk structure bionic design. Background technique

[0002] Most of the current building beams and columns are reinforced concrete structures or steel structures. Concrete is a heterogeneous brittle material. When a small longitudinal deformation occurs, the deformation of various materials in the matrix is ​​inconsistent, which makes the concrete beams and columns crack due to the Poisson's ratio effect. The brittle failure of concrete limits the further development of concrete in engineering applications. Moreover, concrete is an important building material, and the durability protection of concrete structures is also an important issue.
