Description
Technical Field
The invention relates to the technical field of connecting nodes, in particular to a novel flange disconnection type beam-column connecting node.
Background
In recent years, the number of steel structure buildings in China is gradually increased. Steel structures are different from concrete structures, and besides the design of the self components, the nodes are also important design items. A large number of joints adopted in China for a long time are traditional styles, and the styles are difficult to meet the requirements of steel structure buildings of various different forms. Therefore, the development of new nodes with good applicability is imminent.
At present, when steel structure connection design is carried out, beam column connection needs to be strengthened to the node when the checking calculation of the beam column is not satisfied. The following are commonly used as reinforcement means: 1. reinforcing by a cover plate; 2. widening flanges and reinforcing; 3. strengthen the axilla. The purpose of the reinforced end is to move the plastic hinge outwards from the design principle. There is also a way to weaken the outboard beam flange so that this location creates a plastic hinge before the other locations, commonly referred to as a "dog bone" connection, as shown in fig. 3. However, the connection has a high requirement on the machining precision, namely, the weakened part needs to be smooth, and the defects of stress concentration caused by burrs, gaps and the like cannot occur.
Therefore, there is a high demand for a new type of connection node in the market to solve the above problems.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a novel flange disconnection type beam-column connecting joint which is used for solving the technical problems in the prior art, and is convenient to install and manufacture while forming a plastic hinge.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1-2, the present embodiment provides a novel flange-disconnected beam-column connection node, including:
the upper flange plate is a common rectangular plate and comprises a first upper flange plate 21 and a second upper flange plate 24, an upper flange notch 23 is formed between the first upper flange plate 21 and the second upper flange plate 24, and it can be understood that the first upper flange plate 21 and the second upper flange plate 24 are two parts formed by cutting the upper flange plates;
the upper connecting plate 22 is a rectangular plate with a smaller volume, two ends of the upper connecting plate 22 are respectively fixed on the first upper flange plate 21 and the second upper flange plate 24, the central line of the upper connecting plate 22 corresponds to the upper flange notch 23, the cross section of the first upper flange plate 21 is the same as that of the second upper flange plate 24, and the cross section area of the upper connecting plate 22 is smaller than that of the first upper flange plate 21;
the lower flange plate has the same structure as the upper flange plate, the lower flange plate comprises a first lower flange plate 31 and a second lower flange plate 34, and a lower flange cut 33 is arranged between the first lower flange plate 31 and the second lower flange plate 34, and it can be understood that the first lower flange plate 31 and the second lower flange plate 34 are two parts formed by cutting the lower flange plates;
the structure of the lower connecting plate 32 is the same as that of the upper connecting plate 22, two ends of the lower connecting plate 32 are respectively fixed on the first lower flange plate 31 and the second lower flange plate 34, the central line of the lower connecting plate 32 corresponds to the position of the lower flange cut 33, the cross section of the first lower flange plate 31 is the same as that of the second lower flange plate 34, and the cross section area of the lower connecting plate 32 is smaller than that of the first lower flange plate 31;
one end of the web plate 1, the upper flange plate and the lower flange plate is fixed on one side of the web plate 1.
In use, only the upper flange plate will be described below, and the lower flange plate will be the same as the upper flange plate. The cross-sectional area of the upper web 22 is smaller than the cross-sectional area of the first upper flange plate 21, and is arranged to reduce the flexural load-bearing capacity there. In medium and large earthquakes, plastic hinges appear at the weakened positions after the external load exceeds the plastic bending bearing capacity of the positions. Because the upper flange plate is disconnected, the plastic hinge is formed more thoroughly, and greater energy consumption capability can be provided. The working principle of the lower flange plate is the same as that of the upper flange plate, so that the description is omitted.
In this embodiment, a gap is formed between the upper flange plate and the lower flange plate, and the gap can be used for connecting other beam-column structures.
