Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to an assembled bracket for a reinforced concrete column. Background Technique

[0002] Steel pipe seats are usually applied to support members such as municipal engineering pipelines, cables, equipment, and maintenance steel platforms, and are an important part of the support structure stress system. During the laying process of engineering pipelines, in order to reduce construction costs and on the premise of meeting structural safety, existing building and structure frame columns are often used to install pipe seats. At present, the following several connection methods are mainly adopted between the steel pipe seat and the reinforced concrete column:

[0003] 1. Embedded steel plates or bolts. This method is only applicable to the situation where the pipe seat and the reinforced concrete frame column are constructed simultaneously. The pipe seat embedded parts can be set according to the installation requirements during the construction of the concrete column. Before pouring the concrete, the steel plates or bolts are embedded into the side wall of the reinforced concrete frame column, and the pipe seat is installed after the construction of the reinforced concrete column is completed;

[0004] 2. Post-inserted reinforcement or expansion bolt connection. This method is to install the pipe seat on the existing reinforced concrete frame column. It is necessary to drill holes in the existing reinforced concrete column body, implant steel bars or drive in expansion bolts, and then install and connect the pipe seat with the embedded parts.

[0005] The installation method of embedded steel plates or bolts requires embedding during the construction of the reinforced concrete column. However, from the actual engineering situation, the most common situation is to install on the existing formed reinforced concrete column. In such cases, the method of embedded steel plates or bolts is not applicable. If post-inserted reinforcement or expansion bolt connection is adopted, drilling is required on the existing column body, which is very easy to damage the longitudinal stressed steel bars or stirrups of the column, having an adverse impact on structural safety.

[0006] The existing connection methods between the steel pipe seat and the reinforced concrete column usually have the following disadvantages:

[0007] 1. Adopting post-inserted reinforcement or expansion bolt connection. This method has a certain degree of destructiveness. It is necessary to drill holes in the existing reinforced concrete column body, implant steel bars or drive in expansion bolts, and then install and connect the pipe seat. When using post-inserted reinforcement or expansion bolts, drilling is required on the existing column body, which is very easy to damage the longitudinal stressed steel bars or stirrups of the column, having an adverse impact on structural safety.

[0008] 2. When using post-inserted reinforcement or expansion bolts for connection, the steel pipe seat lacks flexibility. The connection position between the steel pipe seat and the reinforced concrete column, especially the installation height, is fixed, and the installation height and position cannot be adjusted after installation;

[0009] 3. The construction period of the steel pipe seat connected by planting steel bars or expansion bolts is long. After the construction is completed, the pipe seat cannot be recycled. Summary of the Invention
