Problems solved by technology

However, at present, due to the inherent damage of recycled aggregates and the high water absorption rate caused by the adsorption of a layer of old mortar on its surface, the strength, shrinkage and durability of recycled concrete are poorer than ordinary concrete. The earth limits its scope of use

Embodiment Construction

[0017] Steel frame-steel tube recycled concrete cross-section composite column is composed of steel frame, steel tube, steel frame and concrete. Steel frame 5 is welded by steel plate. The steel pipe 3 is located at the core of the cross-shaped column, the concrete 2 is recycled concrete, and the recycled concrete 2 is located inside and outside the steel pipe 3 and inside the cross-shaped column surrounded by hoops and 4 bars. The steel frame is welded into a T shape by steel plates. The corners of the cross-shaped column surrounded by the stirrups 4 are equipped with longitudinal steel bars 1 .

[0018] The specific process is as follows:

[0019] 1. Weld the steel plate into a steel frame according to the regulations;

[0020] 2. Fix the steel frame and steel pipe by welding or bolting, and keep it vertical or at a certain angle;

[0021] 3. Binding steel skeleton;

[0022] 4. Support formwork on the outside of the steel skeleton;

[0023] 5. Fully mix recycled concret...

Abstract

A related steel rib-steel pipe regenerated-concrete combined column with a cross-shaped section is composed of a steel rib, a steel pipe, a steel skeleton and concrete; the steel rib is formed by welding steel plates, and is disposed on a limb of the cross-shaped column formed by stirrups in a circle; the steel pipe is at the core of the cross-shaped column; concrete is regenerated concrete and is at the interior and the exterior of the steel pipe and the interior of the cross-shaped column limb formed by stirrups in a circle; the steel rib is T-shaped by welding the steel plates; and corners of the cross-shaped column formed by stirrups in a circle are provided with vertical steel bars. Due to the fact that the regenerated concrete is at the interior and the exterior of the steel pipe, resource is saved and environment is protected. The steel skeleton constrains concrete and enhances the bearing capability of the column. The combined column is a main member of a framework structure of high-rise and wide-span buildings, and has the characteristics of high bearing capacity, high rigidity, light weight, good plasticity and toughness, good impact resistance and fatigue resistance, excellent earthquake-proof performance, good endurance, energy saving, environment friendliness and the like.

Description

technical field [0001] The invention relates to a concrete component, in particular to a concrete cross-shaped column used in civil engineering, which is a novel cross-section composite column. Background technique [0002] In the current society, with the development of the economy and the improvement of residents' living standards, people have higher and higher requirements for housing, especially for housing structure and living room layout. Because the cross-sectional size of ordinary concrete columns is often larger than the thickness of the wall, it affects the use of indoor space, and it is difficult to meet the requirements of architectural beauty. In order to solve this problem, the structural form of reinforced concrete cross-shaped column appeared. The advantages of the reinforced concrete cross-shaped column structure system are more prominent, and scholars and experts at home and abroad have conducted extensive and in-depth research on it. The theoretical syst...
