Problems solved by technology

However, hollow interlayer concrete-filled steel tube columns mainly rely on their own strength to resist earthquakes. Under repeated loads, large stresses will be generated inside the components, and brittle failures are prone to occur.

Embodiment Construction

[0018] The present invention includes circle-covered circle, square-covered square, square-covered circle, round-covered square, and rectangular-covered rectangular section forms, and is characterized in that it consists of an outer steel pipe 1, an inner steel pipe 2, interlayer concrete 3 and a rubber mixture 4, with two inner and outer layers The steel pipes are fixed by welding or bolting, wherein the interlayer concrete 3 is located in the middle of the double steel pipes, the rubber compound 4 is filled in the inner steel pipes, and the interlayer concrete 3 is self-compacting concrete.

[0019] The specific process is as follows:

[0020] 1. According to the bearing capacity checking calculation, select the inner and outer two layers of steel pipes and interlayer concrete;

[0021] 2. Pour 40~50mm cement mortar at the bottom of the inner steel pipe, and fix the inner and outer two layers of steel pipes by welding or bolting to keep them vertical or at a certain angle; ...

Abstract

The invention is a novel double steel pipe concrete anti-seismic column with built-in rubber compound. Including circle in circle, square in square, circle in square, square in circle, and rectangle in rectangular cross-section, it is composed of outer steel pipe, inner steel pipe, interlayer concrete and rubber mixture. The concrete is placed between the double steel pipes, the rubber compound is filled in the inner steel pipes, and the sandwich concrete is self-compacting concrete. The rubber compound is located inside the inner steel pipe, which has a good energy dissipation and shock absorption effect, can effectively absorb earthquake energy, and can also effectively prevent fires; the double steel pipe concrete anti-seismic column with built-in rubber compound has a relatively low self-weight. The invention is the main component of the frame structure in high-rise and long-span buildings, and has the characteristics of high bearing capacity, light weight, good plasticity and toughness, good impact resistance and fatigue resistance, good earthquake resistance, good durability and the like.

Description

technical field [0001] The invention relates to a concrete member, in particular to a steel pipe concrete column used in civil engineering, which is a double steel pipe concrete anti-seismic column built with a rubber compound and a construction method thereof. Background technique [0002] At present, the seismic resistance of buildings mainly depends on the stiffness of structural components. Under repeated loads such as earthquakes, structural components can only rely on their own strength to absorb the energy of earthquakes. In this case, the deformation of large rigid components is very large. If it is small, it will inevitably generate excessive internal force. When some strong earthquakes come, the structural system is extremely prone to brittle failure, endangering the property safety and life safety of the people. In addition, in some super high-rise and long-span buildings, the size of components is often made large or structural systems such as shear walls and cy...
