Fiber reinforced concrete frame structure

Abstract

The invention provides a fiber reinforced concrete frame structure, and belongs to the field of concrete members. The fiber reinforced concrete frame structure comprises a plurality of frame units formed by connecting a plurality of reinforcement cages, each frame unit comprises a plurality of concrete beams and concrete columns which are crossed and vertically arranged, and the concrete beams andthe concrete columns are composed of the reinforcement cages and concrete poured in the reinforcement cages; prestressed fiber reinforced composite sheets are fixedly clamped on the surfaces of the concrete beams and the surfaces of the concrete columns through anchorage devices, the clamping anchorage devices are connected with the reinforcement cages, and reinforced fiber reinforced concrete joints are formed at the joints of the concrete beams and the concrete columns; and each reinforcement cage comprises in-column profile steel and in-beam profile steel, the periphery of the in-column profile steel is connected with one piece of in-beam profile steel, the in-column profile steel and the in-beam profile steel form a reinforcement cage structure, and fiber reinforced concrete is pouredinto the reinforcement cage structure. The structure adopts a limiting material to effectively improve the tensile strength and the crack resistance of the concrete in a plastic area, and the deformability and the bearing capacity of the plastic area can be enhanced.

Description

technical field [0001] The invention belongs to the field of concrete components, and in particular relates to a fiber reinforced concrete frame structure. Background technique [0002] With the development of society, the urban population has increased year by year, and the increase in population has brought about the tension of land use issues. In order to make full use of land resources, there are more and more types of buildings and their heights are increasing, which also makes people pay more and more attention to the performance and safety of buildings. [0003] Concrete frame structure is the most common building structure at present. It is composed of steel frame and concrete poured inside, and has good earthquake resistance, ductility and bearing capacity. Usually, the flexural rigidity, bearing capacity and durability of the joints of the concrete frame structure are relatively weak, so it is very important to improve the performance of the joints. At the same t...

Problems solved by technology

At the same time, the existing concrete frames are bound by steel bars and cannot be modularized. They are all bound on site, and the production efficiency is low.
