Embodiment Construction

[0039] Examples see Figure 1-8 As shown, this H-shaped steel beam and H-shaped steel column weak axis variable beam height assembled joint includes H-shaped steel column 1 and H-shaped steel beam 2, and the node also includes column seals 7, T-shaped connectors 3, L-shaped connector 4 and bolts.

[0040] see figure 1 , Figure 6 As shown, the column seal 7 is composed of a column seal plate 7.1, a beam upper flange stiffener 7.2 and a column seal plate stiffener 7.3. The column seal plate 7.1 is vertically arranged, and its lower part has a reserved bolt hole 7.4, and the reserved bolt hole 7.4 The number of is four, distributed in a rectangle. The upper flange stiffener 7.2 of the beam is vertically connected with the top edge of the column sealing plate 7.1 to form an L shape, the stiffener 7.3 of the column sealing plate is vertically connected at the angle between the column sealing plate 7.1 and the stiffener 7.2 of the upper flange of the beam, and the front side of ...

Abstract

The invention discloses an H-shaped steel beam and H-shaped steel column minor axis variable beam height fabricated node and a construction method thereof. The node comprises an H-shaped steel column, an H-shaped steel beam, a column sealing piece, a T-shaped connection piece, an L-shaped connection piece and bolts. The column sealing piece consists of a column sealing plate, a beam upper flange stiffening rib and a column sealing plate stiffening rib; the T-shaped connection piece consists of an upper flange plate connection plate which is arranged horizontally and a web connection plate which is perpendicular to the bottom surface of the upper flange plate connection plate; the L-shaped connection piece consists of a lower flange plate connection plate which is arranged horizontally and a column connection plate which is perpendicular to the lower flange plate connection plate downward. All accessories required by the node are prefabricated in a factory, the requirement of equal-strength connection in the process of changing the section of the H-shaped steel beam in a certain range can be met, high-strength bolts are adopted by a construction field node so as to realize the fabricated connection, and the node is high in rigidity and high in connection speed, and can meet the requirement of the fabricated construction of a steel structure.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a steel structure beam-column connection node and a construction method thereof. Background technique [0002] In multi-story and high-rise steel structures, H-shaped steel beams and H-shaped steel columns are used as the main load-bearing components, and the nodes connecting H-shaped steel beams and H-shaped steel columns play the role of transmitting beams, column bending moments, and shear forces. The overall mechanical performance has a significant impact. The full-welded connection and bolt-welded connection of H-shaped steel beams and columns have high structural connection stiffness and good mechanical performance, but stress concentration is prone to occur due to the existence of welds, and the on-site construction is difficult and expensive, which cannot meet the requirements of steel beams and columns. Structural construction efficiency r...
