Embodiment Construction

[0025] Such as Figure 1~3 As shown, a fully prefabricated composite frame node, including a square concrete-filled steel tube concrete upper column and a square concrete-filled steel tube lower column; Shear key 2; the two adjacent columns of the square concrete-filled steel tube concrete upper column and the two complementary columns of the square concrete-filled steel tube concrete lower column are respectively pre-welded beam connection joints 3; the square concrete-filled steel tube upper column and the square concrete-filled steel tube lower column For butt weld connection, the inserted steel shear key 2 is inserted into the single-mouth groove 1; the beam connection joint 3 is welded together with the upper column of the square steel tube concrete and the lower column of the square steel tube concrete.

[0026] Specifically, the upper and lower columns of the square steel tube concrete are made of Q345 steel plates with a wall thickness of 10-15mm and a minimum width-to...

Abstract

The invention discloses a total prefabricated combination frame joint and a manufacture method thereof. The joint comprises column-column connection between total prefabricated square steel tube concrete columns and beam-column connection between an H-shaped steel beam and a total prefabricated square steel tube concrete column; a single notch is formed in the connection section of a square steeltube concrete lower column; an interpolation type profile steel shear key is arranged on the connection section of an upper column; H-shaped steel connectors are respectively pre-welded with connectorcolumn surfaces of the upper and lower columns; ducts are reserved on the connector column surfaces of the upper and lower columns; the upper and lower columns are connected with each other through butt welds; externally coated steel plates in the position of a seam are mounted and fixed through opposite-pull screws and are welded with a H-shaped steel connector into a whole body; steel columns are connected with each other through web high-strength bolts in a flange welding mode. The total prefabricated combination frame joint avoids field wet operation, is high in construction operability,reduces the field welding difficulty from the design level, and realizes connection of total prefabricated combination frame joints.

Description

technical field [0001] The invention relates to an assembled node, in particular to a fully prefabricated assembled mixed frame node and a manufacturing method thereof. Background technique [0002] With the rise and promotion of prefabricated buildings, the problem of prefabricated node connection has become a bottleneck restricting the development of prefabricated buildings. In order to adapt to the development of building industrialization and actively promote the application of composite structures in the field of high-rise buildings, the design idea of ​​fully prefabricated hybrid frame nodes was formed. [0003] At present, the joint connection of prefabricated concrete structures is mostly wet work, which brings inconvenience to construction; and at this stage, the seismic performance of prefabricated concrete structures in China is flawed, so the introduction of composite structural systems will be a good choice. The composite structure has the characteristics of ea...
