Description

Ultra-high performance concrete steel connection node frame structure Technical Field The invention relates to the technical field of building structures, in particular to an ultra-high-performance concrete steel connecting node frame structure. Background In the field of building engineering, a frame structure is one of the most widely applied structural forms, and currently, the main stream of frame structures is mainly divided into two main types of steel structure frames and concrete structure frames, but the two types of structures have technical defects which are difficult to overcome respectively, and the comprehensive requirements of building engineering on manufacturing cost, construction efficiency, fireproof performance, durability and environmental protection cannot be met at the same time, so that popularization and application of the frame structure in various building scenes are limited. The traditional steel structure building has the remarkable advantages of light weight, high construction efficiency, short construction period, high recycling rate and low carbon emission of the components, is widely applied to large-span, high-rise and industrial buildings, but simultaneously has outstanding technical short plates, namely, on one hand, the steel structure material is relatively high in cost, so that the overall building cost is relatively high, the engineering investment cost is increased, on the other hand, the steel is relatively poor in fireproof performance, easy to deform and unstably occur in a high-temperature environment, complex fireproof protection measures are required to be additionally arranged, the construction difficulty and the construction cost are further increased, and in addition, the steel is easy to rust and corrode in the natural environment after long-term exposure, so that the structural durability is reduced, the maintenance is required to be regularly carried out, and the subsequent maintenance cost is relatively high. Compared with a steel structure, the traditional concrete structure has the advantages of good fireproof performance, excellent durability and relatively low manufacturing cost, is widely applied to civil buildings and multi-layer buildings, but has obvious defects that the construction process of the concrete structure is complex, the on-site pouring workload is large, the construction speed is slow, the engineering requirements of a short construction period are difficult to meet, meanwhile, the recycling difficulty of concrete structure materials is high, the recycling proportion is low, the construction wastes generated after the building is dismantled are difficult to effectively recycle, the resource waste is caused, and in addition, a large amount of carbon emission is generated in the concrete production process, so that the method does not accord with the current industry trend of green building and low-carbon development. In order to take account of the advantages of the steel structure and the concrete structure and overcome the defects of the steel structure and the concrete structure, the skilled person tries to develop a combined structure, but the existing combined structure adopts common concrete and steel for simple combination, and the core advantages of the two materials cannot be fully exerted, so that either the manufacturing cost cannot be effectively reduced, the fireproof performance and the durability cannot be improved, or the construction efficiency and the structural stability cannot be guaranteed, and various problems of the traditional structure cannot be fundamentally solved.
