Embodiment 1

[0035] Such as Figure 5 What is shown is that the corbel 3 is connected to the column web 22, that is, the weak axis connection. The column web 22 and the corbel 3 are connected by welding in the workshop, and the transverse reinforcing rib 8 on the column 2 corresponds to the upper and lower flanges 31 and 32 of the corbel. The box girder 1 is welded and spliced ​​in the workshop to form a box girder with an H-shaped end. The H-shaped end includes an upper flange 41 , a lower flange 42 and a web 43 . After the box girder 1 and column 2 are transported to the construction site, align the upper and lower flanges 41, 42 of the box girder end with the upper and lower flanges 31, 32 of the corbel, and align the web 43 of the end of the box girder with the corbel The leg web 33 is aligned, and after alignment, the connecting plate 5 is set on both sides of the flange and the web, and the H-shaped end flange and the corbel flange, the end web and the corbel web are fastened by bol...

Embodiment 2

[0037] Such as Figure 6What is shown is that the corbel 3 is connected to the column flange 21, that is, the strong axis connection. The column flange 21 and the corbel 3 are connected by welding in the workshop, and the transverse reinforcing ribs on the column 2 correspond to the upper and lower flanges 31 and 32 of the corbel. The box girder 1 is welded and spliced ​​in the workshop to form a box girder with an H-shaped end. The H-shaped end includes an upper flange 41 , a lower flange 42 and a web 43 . After the box girder 1 and the column 2 are transported to the construction site, the upper and lower flanges 41, 42 of the box girder end are aligned with the upper and lower flanges 31, 32 of the corbel, and the web plate 43 of the end of the box girder is aligned with the corbel. The leg web 33 is aligned, and after alignment, the connecting plate 5 is set on both sides of the flange and the web, and the H-shaped end flange and the corbel flange, the end web and the cor...

Embodiment 3

[0039] In the above-mentioned prefabricated node connection between the box beam and the column, the column is an H-shaped structure. In practical applications, the column can also be a regular structure such as a box-shaped, circular, or other special-shaped structure. Combine now Figure 7 The connection between the box-shaped beam and the box-shaped column shown is explained. The box-shaped column 9 is assembled from box-shaped wall panels 91 . The box-shaped column 9 is provided with a transverse reinforcing rib 8 inside. The box-shaped column 9 and the corbel 3 are connected by welding in the workshop, and the transverse reinforcing rib 8 provided inside the box-shaped column 9 corresponds to the upper and lower flanges 31 and 32 of the corbel. The box girder 1 is spliced ​​into a box girder with an H-shaped end by welding in the workshop, and the H-shaped end includes an upper flange 41 of the end, a lower flange 42 of the end and a web 43 of the end. After transporting...

Abstract

The invention relates to a box type beam and column connecting assembly type node preparation technology and a node thereof. The node comprises a box type beam, a vertical column and a bracket, the end of the box type beam forms an H-type end through transition, the H-type end comprises an end upper flange, an end lower flange and an end web plate; the vertical column is connected with the bracketthrough welding, and the bracket is an H-type bracket which comprises a bracket upper flange, a bracket lower flange and a bracket web plate; the H-type end is in butt joint with the flanges and theweb plate of the H-type bracket, connecting plates are arranged on the two sides of the flanges and the web plate and firmly connected through bolts, and then the box type beam and column connecting assembly type node is formed. Accordingly, the manufacturing cost is greatly lowered, on-site construction is more convenient, the labor intensity is lowered, box type beam node complete assembly connection is achieved, the box type beam and column connecting mounting speed is increased, and the project construction period is shortened.

Description

technical field [0001] The invention relates to a preparation process for a joint between a box beam and a column, in particular to a preparation process for an assembled joint connecting a box beam and a column through bolts. [0002] The invention also relates to a box-shaped beam-to-column connection fabricated node processed through the above node preparation process. Background technique [0003] In recent years, steel structures have developed rapidly in various industries in my country because of their light weight, good seismic performance, short construction period and recyclable materials. With the development of society and the improvement of people's environmental awareness and energy-saving awareness, the installations and equipment in many industries are developing towards large-scale and large-scale development. To a large extent, this puts forward higher requirements for the design and construction of steel structures. Require. At the same time, the design ...
