Steel pipe and desert sand light aggregate concrete combination column

Abstract

The invention discloses a steel pipe and desert sand light aggregate concrete combination column. The steel pipe and desert sand light aggregate concrete combination column comprises a steel pipe anddesert sand light aggregate concrete poured into the steel pipe. Preparation raw materials of the desert sand light aggregate concrete include desert sand. According to the steel pipe and desert sandlight aggregate concrete combination column, the bearing and deformation capacity of structural elements can be well guaranteed, and good heat insulating and heat resisting performance is achieved under the condition that the bearing requirements are met. The combination column is low in mass, materials are easy to draw, and the combination column has the accessory attributes of being simple in structure and convenient to transport and is especially suitable for remote towns with insufficient material supply, low human quality and deficient technical force in northwest regions. The desert sandlight aggregate concrete is restrained by the steel pipe, the hoop effect of the steel pipe is enhanced, the desert sand light aggregate concrete in the steel pipe is in a three-dimensional pressed state, the deformation of the desert sand light aggregate concrete is restrained, and the steel pipe and desert sand light aggregate concrete combination column has the beneficial effects of being convenient to construct, high in bearing force and good in anti-seismic performance and achieving energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular, the invention relates to a steel-pipe desert sand lightweight aggregate concrete composite column. Background technique [0002] With the acceleration of economic development and urbanization, there are more and more concrete structural projects such as high-rise buildings, bridges, high-speed railways, and large tunnels, and the demand for concrete is increasing. River sand is a very important raw material in the concrete preparation process. The increase in the demand for concrete has led to an increase in the mining demand for river sand, and the sand mining load in the river has increased. , and due to the shortage of river sand resources, the price of river sand has increased significantly, and the construction cost has increased. [0003] On the other hand, the west of my country is currently at the peak of urban infrastructure development, and the desert sa...
