Problems solved by technology

[0007] At present, there are some deficiencies in the performance and use of CFST columns, such as the high price of steel pipe materials and high processing requirements; the fire resistance of CFST columns is poor, and other measures need to be taken to increase the fire resistance limit; the material properties of steel pipes and concrete are very different. , it is easy to cause the steel pipe and concrete to be empty, etc.
In addition, the concrete-filled steel tube columns need regular maintenance during use, which increases the cost of use

Embodiment Construction

[0027] As shown in the accompanying drawings, the present invention is characterized in that the casing of the reinforced concrete column 2 is a prefabricated active powder concrete casing 1, such as figure 1 shown. It is also characterized in that the inside of the active powder concrete sleeve 1 is equipped with longitudinal steel bars 3 and stirrups 4, such as figure 1 and figure 2 shown. It is also characterized in that the steel bars configured in the reinforced concrete column 2 are longitudinal steel bars 5 and spiral stirrups 6, such as figure 1 and figure 2shown. During implementation, firstly, the reinforcement cage composed of the longitudinal reinforcement 3 and the stirrup 4 in the active powder concrete casing is bound, and placed in the mold for making the prefabricated active powder concrete casing 1; the prepared active powder concrete is poured to make a prefabricated Reactive powder concrete casing 1; remove the formwork 1 day after pouring, and place...

Abstract

The invention discloses a sleeve reinforced concrete column. The sleeve reinforced concrete column is characterized in that: a sleeve (1) of a reinforced concrete column (2) is a prefabricated active powder concrete sleeve. The sleeve reinforced concrete column has the advantages of convenience for construction, low cost, high axial bearing capacity, good shock resistance, predominant fireproof performance, excellent durability and the like, meanwhile, saves more resources and energy, and accords with the requirements of sustainable development.

Description

technical field [0001] The invention mainly relates to the field of building structures in civil engineering, in particular to a casing reinforced concrete column that can be used as a structural column. Background technique [0002] With the progress of the society and the continuous development of the economy, the modern construction industry has higher and higher requirements for building materials and building structures. The materials and structures must be able to adapt to the development of modern engineering structures to large spans, towering towers, and heavy loads and to withstand harsh conditions. The use environment and durability requirements meet the requirements of modern construction technology industrialization, and have high load-bearing capacity, good deformation capacity, good fire resistance and good performance / cost ratio. In the past 30 years, the emergence and development of new composite materials and composite structures have greatly promoted the d...
