specific Embodiment 1

[0053] like Figure 1 to Figure 6 As shown, the connection node between the prefabricated web through-type concrete-filled steel tube column and the steel beam (hereinafter referred to as the connection node) includes a steel tube concrete column 101 and four steel beams connected to the steel tube concrete column 101. The steel beams here are engineering The beams 104 and the concrete-filled steel tube columns 101 extend vertically, and the I-beams 104 extend horizontally. The four I-beams 104 are arranged crosswise in the shape of a "ten". The concrete-filled steel tube column 101 in this embodiment is a square concrete-filled steel tube column with a rectangular cross section.

[0054] like figure 1 As shown, in order to connect the steel tube concrete column 101 and four I-beams 104, the first node plate 102 and the second node plate 103 are penetrated in the steel tube concrete column 101, and the plates of the first node plate 102 and the second node plate 103 The plan...

specific Embodiment 2

[0062] like Figure 7 to Figure 9 As shown, the difference from Embodiment 1 is that in this embodiment, a slot 206 is opened at the end of the first gusset plate 202 facing the I-beam 204 , and the slot 206 here can be used for the I-beam 204 The web 2041 and the flange are inserted and then fixed. Specifically, such as Figure 8 As shown, a first gusset plate connection hole 207 is opened on the first gusset plate 202, as Figure 9 As shown, a web connection hole 2042 is opened on the web 2041, and the first gusset plate 202 and the web 2041 are connected together by bolts. The connection mode between the wing plate 205 and the first gusset plate 202 is the same as that in Embodiment 1, and will not be described in detail here. It should be noted that, in this embodiment, the slot on the wing 205 corresponds to the slot 206 . The connection mode between the second gusset plate 203 and the I-beam 204 is consistent with that in Embodiment 1, and the connection mode between...

Embodiment 1

[0065] In Example 1, bolts are used to fix the two cover plates, the web plate and the gusset plate. In this embodiment, one of the web plate and the gusset plate is connected to the cover plate by welding, and the other is connected to the bolts, or both are connected by welding.

Abstract

The invention relates to the technical field of building structure engineering, in particular to a prefabricated web through type concrete-filled steel tubular column and steel beam connecting joint.The connecting joint comprises a vertically-extending concrete-filled steel tubular column and four steel beams distributed in a crossed mode; the connecting joint comprises a first joint plate and asecond joint plate; the first joint plate and the second joint plate are distributed in a crossed mode; the first joint plate horizontally penetrates through the concrete-filled steel tubular column;a groove hole allowing the second joint plate to penetrate through is formed in the first joint plate; the second joint plate penetrates through the concrete-filled steel tubular column and the firstjoint plate at the same time; the first joint plate and the second joint plate are both welded to the column wall of the concrete-filled steel tubular column; and the steel beams are fixedly installedat the two ends respectively. The prefabricated web through type concrete-filled steel tubular column and steel beam connecting joint solves the problem of assembly type operation of a closed-sectioncolumn, concrete-filled steel tubes do not need to be disconnected in a joint area, flanges of the steel beams and the column walls are not welded any more, weld joint breakage is avoided, and the anti-seismic property is excellent.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a connection node between a prefabricated web through-type concrete filled steel pipe column and a steel beam. Background technique [0002] The connection between the steel tube concrete column and the steel beam can ensure the bearing capacity and reliability, realize the aesthetic appearance, and form a frame system with simple shape and flexible layout. Therefore, the application prospect of the connection between CFST columns and steel beams in high-rise and super high-rise buildings is very good. [0003] The existing joints between CFST columns and steel beams usually include CFST columns. The inside of the CFST column is fixed with an inner gusset plate, and the outside is fixed with a column outer plate. The ends of the beams are attached to the outer panels of the columns. The current connection nodes have some disadvantages in actual use: steel...
