Embodiment Construction

[0026] In the present invention, the H-shaped steel column is composed of a web 7 and two flanges 6 arranged at both ends of the web 7, between the two flanges 6, a gusset plate 1 is welded at a position flush with the outer edge of the flange 6 . A stiffening plate 2 is welded at the vertical center line inside the gusset plate 1, and the gusset plate 1 and the stiffening plate 2 are perpendicular to each other. The stiffener 2 is trapezoidal, wherein the short bottom of the trapezoid is welded to the gusset plate 1 , and the long bottom is welded to the web 7 of the H-shaped steel column. Two supporting plates 3 are welded on the H-shaped steel column, the two supporting plates 3 are flush with the lower edge of the gusset plate 1, and perpendicular to the web 7 of the H-shaped steel column, two flanges 6, and the stiffening plate 2, and the stiffening plate 2 is symmetrical about the axis of symmetry. The H-shaped steel beam is vertically welded to the rectangular end pla...

Abstract

The invention discloses an H section steel girder-column minor axis connecting end plate node and a preparing method of the H section steel girder-column minor axis connecting end plate node, wherein the H section steel girder-column minor axis connecting end plate node is characterized in that a T-shaped combined body consisting of a node plate and a stiffening plate is welded on an H section steel column, a supporting plate is welded at the bottom of the T-shaped combined body, an end plate is welded at one end of the H section steel column, the node plate and the end plate are connected through high-strength bolts, and two spaces defined by the H section steel column, the T-shaped combined body and the supporting plate are filled with concrete fillers. The preparing method comprises the following steps that the node plate and the stiffening plate are welded into the T-shaped combined body; the T-shaped combined body and the supporting plate are welded on the H section steel column; the end plate is welded on the H section steel column; the end plate and the node plate are connected by the high-strength bolts; a rectangular region of a node area is poured with concrete. The H section steel girder-column minor axis connecting end plate node and the preparing method have the advantages that the respective advantages of steel and concrete are fully utilized, the anti-seismic performance is good, the bearing capability is great, and the construction is simple and convenient.

Description

technical field [0001] The invention relates to an H-shaped steel beam-column weak shaft connection end plate node and a preparation method thereof, belonging to the field of building structure engineering. Background technique [0002] Steel frame is a safe, reliable, lightweight, high-strength, and fast-construction structural system, which has been widely used in architectural structural engineering. In earthquake disasters, due to unreasonable design and construction, frame joints are often prone to failure prior to structural members, resulting in structural seismic performance that cannot meet the requirements of seismic design. In general, the steel frame system is a frame in both vertical and horizontal directions, that is, both the strong axis and the weak axis of the H-shaped steel column are connected to the H-shaped steel beam. However, due to the difficulties in analysis, design and installation of H-shaped steel beam-column weak-axis connections, there are few...
