Example Embodiment

[0024] Such as Figure 1~2 As shown, a corner steel-clad lightweight aggregate concrete column includes a column made of lightweight aggregate concrete 3. The column is covered with angle steel 1 at each corner along its length direction. The surface is higher than the surface of the column or flush with the surface of the column, the inner surface of the angle steel is reliably bonded to the column, and two adjacent angle steels are connected by transverse stirrups 2, which are welded to the two limbs of the angle steel 1. The inner surface.

[0025] In this embodiment, the cross section of the column is polygonal, and the angle formed by the two limbs of each angle steel is equal to the angle of the corresponding corner of the polygon, and may be less than, equal to or greater than a right angle.

[0026] In this embodiment, the lightweight aggregate of the lightweight aggregate concrete 3 is ceramsite, volcanic slag or coal gangue, wherein the ceramsite is one of shale ceramsit...

Abstract

The invention relates to a lightweight aggregate concrete column with steel-armored corners. The lightweight aggregate concrete column comprises a column body fabricated by lightweight aggregate concrete, wherein the column body is coated with a steel angle at each corner along the length direction; the outer surface of each steel angle is higher than or flush with the surface of the column body; the inner surface of each steel angle is reliably attached to the column body; each two adjacent steel angles are connected through a transverse hoop; the hoops are welded at the inner surfaces of two limbs of the steel angles. The invention also relates to a fabrication technology of the lightweight aggregate concrete column with the steel-armored corners. The fabrication technology comprises the following steps: supporting a template according to a steel design result; welding a steel angle skeleton; pouring the lightweight aggregate concrete; and maintaining. The lightweight aggregate concrete column with the steel-armored corners has the characteristics of having energy-saving and environment-friendly effects, and being high in carrying capacity, good in anti-seismic property, convenient and fast in construction and good in economic benefits on the premise of meeting various performance indexes (carrying capacity, ductility, durability and the like) of the column; the dead load of the column is reduced; the lightweight aggregate concrete column is applicable to large-scale popularization and application, and has significant economic and social benefits.

Description

technical field [0001] The invention relates to a corner steel-clad lightweight aggregate concrete column and a manufacturing process thereof, belonging to the field of building structures. Background technique [0002] In recent years, outsourcing steel concrete columns have been widely used in frame structures with heavy loads, large spans, and high heights because of their high bearing capacity, convenient welding of various small components, and easy laying of process pipelines. Industrial buildings such as thermal power plants that require high welding. [0003] With the rapid development of economy and society, modern buildings are gradually developing towards large-span and high-rise buildings. The capacity of thermal power plant units continues to increase, and the height, span and load of the factory building are getting larger and larger. The cross-section of the outsourcing steel concrete column is often quite large. , leading to a significant increase in the sel...
