Full-bolt socket and spigot type beam column connecting structure of fabricated steel concrete

Abstract

The invention provides a full-bolt socket and spigot type beam column connecting structure of fabricated steel concrete. The beam column connecting structure comprises a steel column, a plurality of I-shaped beams, supporting pieces and connecting pieces, wherein the plurality of I-shaped beams, the supporting pieces and the connecting pieces are arranged on the steel column, the steel column is provided with a hollow cavity for concrete pouring, a plurality of fixing steel bars are arranged in the hollow cavity, the supporting pieces are arranged below the I-shaped beams and connected with the I-shaped beams through bolts, one ends of the connecting pieces are connected with the I-shaped beams through bolts, the other ends of the connecting pieces are inserted into the hollow cavity of the steel column to be connected with the fixing steel bars, and finally concrete is poured for fixing. By means of the combination of steel concrete connection and bolt connection, the beam-column joint has the stability of welding type connection, the construction precision of full-bolt type installation is also reduced, the construction process is simple, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of concrete engineering, and in particular relates to an assembled steel concrete full-bolt socket-type beam-column connection structure. Background technique [0002] The prefabricated concrete structure has the advantages of high degree of industrialization, material saving, low pollution, convenient construction, short construction period, and fast investment recovery. It is the direction of the development of new building industrialization. As far as the prefabricated building industry is concerned, my country's development started relatively late, but after years of vigorous development, prefabricated buildings have entered the fast lane of development. At present, the beam-column connection structures of steel composite structures or steel and concrete composite structures at home and abroad adopt welding or The combination of bolts and welds leads to slow construction on site. After welding, minor adju...

Problems solved by technology

As far as the prefabricated building industry is concerned, my country's development started relatively late, but after years of vigorous development, prefabricated buildings have entered the fast lane of development. At present, the beam-column connection structures of steel composite structures or steel and concrete composite structures at home and abroad adopt welding or The combination of bolts and welds leads to slow construction on site. After welding, minor adjustments to the components are required, and rework is required when construction errors occur. The efficiency and quality are not high. The requirements for component prefabrication accuracy and on-site construction accuracy are extremely high, and construction is difficult to achieve
