Description

Reinforced concrete columns with built-in high-strength or ultra-high-strength concrete core columns

技术领域technical field

本发明涉及土木工程领域的配筋混凝土柱。The invention relates to a reinforced concrete column in the field of civil engineering.

背景技术Background technique

为了满足混凝土柱承载力和抗侧(风、震)的要求，有时需要混凝土柱的截面尺寸过大，为了解决这一问题，曾有人提出过采用内置钢管混凝土芯柱的配筋混凝土柱，但这类柱的钢管要贯穿结构的节点，使得水平构件中的钢筋穿越节点十分困难，不利于施工，而且工程质量也难以保证。In order to meet the requirements of concrete column bearing capacity and lateral (wind, earthquake) resistance, sometimes the cross-sectional size of the concrete column needs to be too large. The steel pipes of this type of column have to penetrate the joints of the structure, making it very difficult for the steel bars in the horizontal members to pass through the joints, which is not conducive to construction, and it is difficult to guarantee the quality of the project.

本发明不但可明显减少柱截面尺寸，使得水平构件中节点施工困难的问题得以克服，它还具有节省钢材，而且可方便施工，工程质量易于保证的特点。The invention can not only significantly reduce the section size of the column, so that the problem of difficult construction of joints in the horizontal member can be overcome, but also has the characteristics of saving steel materials, convenient construction, and easy guarantee of engineering quality.
