Problems solved by technology
For the multi-span portal frame structure with drawn columns, the drawn columns will cause the difference in lateral stiffness of adjacent portal frames, and under the action of transverse wind load, the lateral displacement difference of the portal frame will be caused.
The difference in lateral displacement will cause the torsion of the longitudinal bracket beam, but the main setting of the bracket beam is mainly used to bear the vertical load, and its own torsional rigidity is poor
In actual engineering, designers usually do not consider the space effect between each portal frame, but use the plane modeling calculation method to design each portal frame, and the connection between the bracket beam and the portal frame beam is High-strength bolts are used for rigid connection, and the torsion of the bracket beam caused by the extraction of columns is not considered in the analysis and calculation

Embodiment Construction
[0016] The technical solution of this patent will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] Such as Figure 1-4 , the connection node disclosed in the present invention includes a horizontally arranged upper beam 1 and an upper beam 2; during use, a longitudinally arranged lower beam below the upper beam, the upper beam and the lower beam are arranged crosswise; the upper beam can be a door Type rigid frame structure rigid frame beam, the lower beam 2 plays a supporting role, which can be H-shaped steel or the like.
[0018] A hinge assembly is provided at the intersection of the upper beam and the lower beam; the hinge assembly includes: a hinge upper part 10 installed on the lower surface of the upper beam; a sliding assembly is provided on the upper surface of the lower beam, and the sliding assembly A hinge lower part 9 is installed on the upper surface; the hinge upper part and the hinge lower pa...

The invention discloses a connecting node, which comprises an upper beam horizontally arranged, and a lower beam longitudinally arranged under the upper beam. The upper beam and the lower beam are arranged in a crossing way; a hinge assembly is arranged at a position of a crossing point of the upper beam and the lower beam, and comprises a hinge upper part arranged on a lower surface of the upperbeam; a sliding assembly is arranged on an upper surface of the lower beam; a hinge lower part is arranged on an upper surface of the sliding assembly; the hinge upper part and the hinge lower part are connected through a pin shaft. According to the scheme, the hinged node reliably transfer a vertical load of the upper beam to a directional sliding framework, so that the directional sliding and the vertical load transferring of the connecting node are realized. The engineering problems that a bracket beam is tortured, and a calculation model and a structure actual force are assumed to be inconsistent are solved.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a bracket beam connection node. Background technique [0002] In order to meet the functional requirements of large-span and no inter-column support for large-scale warehouse-style industrial buildings, columns are often treated in the design of multi-span portal frame structures to achieve the functional requirements of the building, and bracket beams are set for the extraction of columns. Portal frame beams to support. For the multi-span portal frame structure with drawn columns, the drawn columns will cause the difference in lateral stiffness of adjacent portal frames, which will lead to the difference in lateral displacement of the portal frame under the action of transverse wind load. The difference in lateral displacement will cause the torsion of the longitudinal bracket beam, but the main configuration of the bracket beam is mainly used to bear the vertical load, an...
