Problems solved by technology

However, in the current construction process, there is no mature process for the positioning and alignment of double pipes, and there is no effective tool to ensure the alignment effect. The personal experience and naked eye operation level of the construction personnel are often relied on, and scaffolding needs to be erected on the construction site, which occupies a relatively large area. Large space and resources, cumbersome operation and low precision are not conducive to the effective and rapid development of double-pipe composite structural parts during the construction process.

Abstract

The invention discloses a double-tube centering device. The double-tube centering device comprises T-shaped connecting parts, a fastening bolt, an adjustable bolt, a puller bolt, a long nut, a fixing bolt, an inner tube, an outer tube and a bottom plate, wherein the inner tube and the outer tube are both arranged on the bottom plate; the inner tube is located in the outer tube, and a space is reserved between the inner tube and the outer tube; and all the multiple T-shaped connecting parts are arranged on the bottom plate and arranged on the periphery of the outer tube. The double-tube centering device can be suitable for double-tube structure parts with various different tube diameters and tube thicknesses, different structure part section hollow rates, different tubes and different section shapes. The device is reasonable in design, ingenious in size, simple in structure, low in cost, high in repeated utilization rate, easy to operate and high in reliability and does not influence concrete pouring in tubes, and used materials can be obtained conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a double-pipe centering device and a realization method thereof. Background technique [0002] With the continuous improvement of concrete strength and various properties, confined concrete components have been greatly developed. For example, the early widely used concrete steel tube concrete components are not only convenient for construction, but also the bearing capacity and ductility of the inner concrete are greatly enhanced under the constraint of the outer steel tube. With the development of new materials, fiber-reinforced polymers (fibre-reinforced polymer, referred to as FRP) with its light weight, high strength, strong plasticity, corrosion resistance and other excellent properties, used to restrain concrete, can effectively reduce the structural performance degradation caused by steel pipe corrosion And other issues. However, due to the solid filling ...
