Description
Technical Field
The invention belongs to the field of buildings, and particularly relates to a hollow stainless steel-concrete-carbon steel tube concrete column base node.
Background
The hollow stainless steel-concrete-carbon steel tube concrete column is a combined structure or member formed by pouring concrete between outer stainless steel and inner carbon steel, the member has large bending rigidity due to the expansion of the cross section, and the bearing capacity of the member is larger than the simple superposition of the bearing capacity of the stainless steel, the concrete and the carbon steel due to the constraint effect of the steel tube on the concrete, and the member has good ductility and stress performance due to damage. During construction, the hollow stainless steel-concrete-carbon steel tube concrete column can be processed by adopting a prefabricating method, or the stainless steel and the carbon steel are concentrically arranged and connected into a double-layer steel tube, and the concrete between the stainless steel column and the double-layer steel tube is poured after the stainless steel and the carbon steel are installed on a construction site.
If the hollow stainless steel-concrete-carbon steel tube concrete column base is connected with the foundation bolt pre-embedded in the concrete foundation by adopting a conventional installation and fixing method, the following problems need to be solved in the actual use process: firstly, because the construction precision of concrete engineering is generally lower than that of steel structure engineering, and the error is relatively large, the problem that the bolt holes of foundation bolts and a steel pipe concrete column base plate are not aligned and need to be corrected often occurs during operation; secondly, bolts cannot be screwed down or can be screwed down after being cleaned due to the pollution of concrete in the construction process of foundation bolts, so that the construction efficiency is low; and thirdly, in the construction process, the bolt thread is damaged due to the fact that workers do not operate normally, and the thread needs to be turned again on site. And fourthly, the stud bolt is easily corroded when exposed in the air, the durable advantage of the stainless steel outer pipe on the members is lost, and if the outer wrapping type stud is adopted, a template needs to be erected, so that time and labor are wasted.
