An assembled connection node

Abstract

The invention discloses a novel assembled connection node. It includes prefabricated corbel columns and prefabricated beams, and also includes screw rods fixed on the corbels and parallel to the prefabricated corbel columns, and the ends of the prefabricated beams rest on the corbels and are fitted by bolts Connection; through the first through hole corresponding to the screw rod at the end of the prefabricated beam; the groove is opened on the surface of the end of the prefabricated beam, including the upper end of the first through hole with a diameter larger than The first groove of the first through hole also includes a second groove perpendicular to the width direction of the prefabricated beam, one end of the second groove communicates with the first groove, and the other end extends to the The edge of the end; the two ends of the tie rod shaft are set as rings, the size of the shaft matches the second groove, the outer diameter of the ring matches the size of the first groove, and the inner diameter The diameter of the first through hole is the same as that of the first through hole; the second through hole is opened parallel to the width direction of the prefabricated corbel column.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a novel assembled connection node. Background technique [0002] Prefabricated concrete building is the most important way of building industrialization. It has many advantages such as improving quality, shortening construction period, saving energy, reducing consumption, and clean production. At present, with the rapid development of my country's economy, the construction industry, like other industries, is undergoing industrial technological transformation, and prefabricated concrete buildings have begun to glow with new vitality. Compared with cast-in-place concrete structures, prefabricated concrete frame structures have It has the advantages of high efficiency and environmental protection, energy saving, less wet work on site, and easy management. Many high-quality buildings have been built with prefabricated structures, and the building system has also used foreign e...

AI Technical Summary

Problems solved by technology

Most of the existing prefabricated joints are mainly connected by wet method, that is, the prefabricated beams and prefabricated columns are integrally connected by post-cast concrete to form rigid joints, but there are disadvantages such as unstable quality and large workload of on-site pouring

However, the dry connection method has problems such as too many components at the nodes, and the connection stiffness cannot meet the requirements.
