Novel assembly type connecting joint

Abstract

The invention discloses a novel assembly type connecting joint. The novel assembly type connecting joint comprises a prefabricated bracket column and prefabricated beams, and further comprises screw rods, first through holes, grooves, tie rods and second through holes, wherein the screw rods are fixed to brackets and parallel to the prefabricated bracket column, the ends of the prefabricated beamsare placed on the brackets and connected with the brackets in a bolt fit mode, the first through holes are formed in the end parts, corresponding to the screw rods, of the prefabricated beams in a penetrating mode, the grooves are formed in the surfaces of the end parts of the prefabricated beams and comprise first grooves formed in the upper ends of the first through holes, the diameters of thefirst grooves are larger than the diameters of the first through holes, the grooves further comprise second grooves perpendicular to the width direction of the prefabricated beams, one ends of the second grooves communicate with the first grooves, the other ends of the second grooves extend to the edges of the end parts, circular rings are arranged at the two ends of rod bodies of the tie rods, the sizes of the rod bodies are matched with the sizes of the second grooves, the outer diameters of the circular rings are matched with the size of the first grooves, the inner diameters of the circular rings are the same as the diameters of the first through holes, and the second through holes are formed in the mode of being parallel to the width direction of the prefabricated bracket column in apenetrating manner.

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.
