Embodiment 1

[0048] see Figure 1-Figure 6As shown, the present invention provides a connection structure between a steel structure stiff frame column and an overrunning beam, comprising a steel structure stiff frame column with a cross section of 1000*1000 mm, and overrun beams arranged on four sides of the steel structure stiff frame column 1 and fill the concrete layer arranged at the connection node between the steel structure stiff frame column and the overrun beam 1, the steel structure stiff frame column includes a rectangular frame column body 3, a column body fitting arranged on the inner surface of the frame column body 3 Rib 4 , square steel column core member 5 arranged in the center of frame column body 3 , C40 high-strength non-shrinkage CGM grouting filler 6 and limit fastening rib 8 filled in square steel column core member 5 . The limiting fastening rib 8 is Ω-shaped, including an intermediate limiting portion 81 and a fixed portion 82 symmetrically arranged at both ends o...

Embodiment 2

[0066] Embodiment 2, a connection structure of stiff frame columns and overrunning beams of a steel structure and its construction method are the same as in Embodiment 1, except that the upper longitudinal reinforcement 11 includes a first longitudinal reinforcement 101 and a second longitudinal reinforcement 102; see Figure 7 and 8 shown.

[0067] The short side of the horizontal connecting plate 7 is fixedly connected to the outer surface of the frame column body 3, the upper end surface of the horizontal connecting plate 7 is fixedly connected to the lower end surface of the first longitudinal rib 101, and the first longitudinal rib 101 is close to the outer surface of the frame column body 3. There is a gap between one side and the outer surface of the frame column body 3, and there is no sleeve outside the end of the first longitudinal rib 101; there are two second longitudinal ribs 102 and are symmetrically arranged on the outer side of the long side of the horizontal ...

Embodiment 3

[0068] Embodiment 3, a steel structure stiff frame column and overrunning beam connection structure and its construction method, is the same as Embodiment 1, and no sleeve is provided at the end of the upper longitudinal reinforcement 11 . It also includes a rectangular horizontal receiving plate 10 arranged directly below the horizontal connecting plate 7, one side of the short side of the horizontal receiving plate 10 is fixedly connected with the frame column body 3, and the upper end surface of the horizontal receiving plate 10 is fixedly connected with the lower end surface of the lower longitudinal rib 12; A vertical connecting plate 14 is also arranged between the receiving plate 10 and the horizontal connecting plate 7 .

Abstract

The invention discloses a steel structure stiff frame column and over-limit beam connecting structure and a construction method thereof, and the steel structure stiff frame column and over-limit beam connecting structure comprises a steel structure stiff frame column, over-limit beams arranged on four side surfaces of the steel structure stiff frame column, and a concrete layer filled at connecting joints of the steel structure stiff frame column and the over-limit beams, the steel structure stiff frame column comprises a rectangular frame column body, column body reinforcing bars arranged on the inner side face of the frame column body, a square steel column core component arranged in the center of the frame column body, filler arranged in the square steel column core component in a filling mode and limiting fastening bars. The ultralimit beam comprises an upper longitudinal bar, a lower longitudinal bar, stirrups bound to the outer side faces of the upper longitudinal bar and the lower longitudinal bar, connecting sleeves and at least one rectangular horizontal connecting plate. The sides, close to the frame column body, of the upper longitudinal bar and the lower longitudinal bar are sleeved with the connecting sleeves. And one side of the short edge of the rectangular horizontal connecting plate is fixedly connected with the frame column body. The method is convenient to construct, accurate in structure, convenient to install and good in stability.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection structure of a rigid frame column of a steel structure and an overrunning beam and a construction method thereof. Background technique [0002] With the continuous improvement of people's living standards, the growing material and spiritual cultural needs put forward new requirements for architecture. In order to adapt to the needs of the times and the vigorous development of society, the construction industry pursues the diversification of architectural structures. As an independent art category, the appearance of buildings (including materials, shapes, colors and even light and shadow changes) provides a rich visual experience, giving people a very Great sense of elegance. [0003] In order to continuously meet new market demands and continue to develop, buildings are getting taller and spans are getting bigger and bigger, but the required construction period ...
