Abstract
The invention provides a full-assembled type cross node with a steel plate concrete cantilever beam. The full-assembled type cross node is mainly composed of concrete columns, the steel plate concrete cantilever beams, installation beam lugs, cantilever beam embedded end plates and the like. The cantilever beam embedded end plates of the four steel plate concrete cantilever beams are welded into a square shape. Each steel plate concrete cantilever beam is respectively provided with two installation beam lugs. Each steel plate concrete cantilever beam is formed by a steel plate frame and concrete poured in the steel plate frame. The full-assembled type cross node ihas the advantages of being high in bearing capacity, good in plasticity and toughness, convenient to construct, good in economical effect, quick in construction speed, suitable for large span, towering and heavy load development of modern engineering structures, capable of bearing severe conditions and capable of meeting the requirements of technical industrialization of modern construction.
Description
technical field [0001] The invention relates to a new type of node of a building structure, in particular to a fully assembled cross-shaped node with a steel plate concrete cantilever beam of an assembled concrete structure. Background technique [0002] Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. The assembly methods of components generally include on-site post-casting laminated layer concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting connection, welding, mechanical connection and lap connection of reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor ...
