Description

Technical Field

[0001] The invention relates to the technical field of industrial and civil steel structure construction, and in particular to a pin shaft adjusting device for a large-span double-hinged arch structure and a pin shaft installation method. Background Art

[0002] The hinged arch building structure is a body that uses a hyperbolic surface. It can not only withstand the pressure of external loads, but also fully disperse the load and reduce the concentration of loads. Through comprehensive stress analysis and calculation, the building can meet the form requirements of the building body and ensure the stability and bearing capacity of the structure when facing different loads. During the installation process, the double-hinged arch bottom plate is the main stress-bearing part of the steel structure. The concentricity of the pin holes reserved in the double-hinged arch structure between each axis directly affects the successful installation of the pins, and plays a key role in the hoisting and alignment of the large-span double-hinged arch structure. The high-precision installation control of the pins of the double-hinged arch bottom plate has a one-time success rate that affects the progress of construction. Now it is necessary to develop a large-span double-hinged arch structure pin precise installation control method to ensure the one-time installation success of the multi-span double-hinged arch structure hoisting alignment, so as to achieve the purpose of rapid construction, strive for construction period, and strive for benefits.

[0003] The existing disadvantages are that the double-hinged arch bottom plate and the pin plate have been factory-produced before the upper arch structure is assembled. The installation process is that the single-span double-hinged arch structure is hoisted and aligned at the same time, and the construction efficiency is low. For the assembly of multi-span double-hinged arch structures, the pin hole installation accuracy control and adjustment technology is not perfect, and the construction efficiency is low. The double-hinged arch bottom plate is connected and fixed to the ground by anchor bolts, and the secondary leveling time is long. Summary of the invention
