Description

Technical Field

[0001] The present application relates to a cladding beam-column connection structure. Background Art

[0002] With the improvement and innovation of building structure, the advantages of steel structure buildings are very obvious. Compared with concrete structure, steel structure has higher strength and better earthquake resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. For this reason, its application in high-rise and super high-rise buildings is becoming more and more mature, but its shortcomings are more obvious, such as heat resistance, fire resistance and corrosion resistance. In order to improve the fire resistance of steel structures, spraying fire retardant coatings is now mostly used, but this method is not effective and does not bring any benefits to the overall structural strength of steel structures. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a cladding type beam-column connection structure, including a vertical column, two vertically arranged vertical connection plates are arranged on the side of the vertical column, a transverse beam is arranged between the two vertical connection plates, and a plurality of connection screws are arranged on the transverse beam and the vertical connection plate, and the transverse beam includes a middle plate, an upper plate and a lower plate are arranged on the upper and lower sides of the middle plate, and a neck portion is arranged at the position where the upper plate and the lower plate are adjacent to the vertical column; a vertical steel cage and a vertical concrete layer are arranged on the outer side of the vertical column, and a transverse steel cage and a transverse concrete layer are arranged on the outer side of the transverse beam. The present application can not only enhance the strength of the steel structure itself, but also greatly improve the fire resistance of the steel structure by arranging the transverse steel cage, the vertical steel cage, and the outer vertical concrete layer and the transverse concrete layer on the outer side of the vertical column and the transverse beam.

[0004] Preferably, an outer protective plate is provided on the side of the neck portion relative to the middle plate, and a side protective plate is provided between the middle plate and the neck portion, and the side portions of the outer protective plate and the side protective plate are arranged to abut against each other so that the neck portion is wrapped therein. The present application can completely wrap the neck portion by providing the neck portion and the outer protective plate and the side protective plate outside. The neck portion is provided between the beams and columns so that the connection between the beams and columns has a certain degree of flexibility, thus avoiding rigid deformation and improving the reliability of the whole during use. At the same time, it can also provide good protection for the neck portion and avoid failure during use.

[0005] Preferably, the outer protective plate and the side protective plate are arranged in the transverse steel cage.

[0006] Preferably, the outer protective plate and the side protective plate are silicone plates.

[0007] Preferably, the vertical column includes a vertical plate arranged in the middle, lateral vertical plates are arranged on both sides of the vertical plate, and the vertical connecting plates are vertically arranged on the lateral vertical plates.

[0008] Preferably, the vertical steel cage comprises a first annular hoop arranged outside the vertical column, and a plurality of vertical ribs are evenly distributed on the first annular hoop.

[0009] Preferably, the transverse reinforcement cage comprises a second annular hoop arranged outside the transverse beam, and a plurality of transverse ribs are evenly distributed on the second annular hoop.

[0010] Preferably, the neck portion is formed by an arc-shaped notch provided on the upper plate or the lower plate. The neck portion of the present application is formed by providing an arc-shaped notch, which has limited influence on the load-bearing capacity of the structure itself, but can improve the impact resistance of the connection and ensure the stability of the structure.

[0011] This application can bring the following beneficial effects:

[0012] 1. This application can not only enhance the strength of the steel structure itself, but also greatly improve the fire resistance of the steel structure by arranging a transverse steel cage, a vertical steel cage, and an outer vertical concrete layer and a transverse concrete layer on the outer side of the vertical column and the transverse beam.

[0013] 2. The present application can completely wrap the neck portion by providing a neck portion and an external outer protective plate and a side protective plate. The neck portion is provided between the beams and columns so that the connection between the beams and columns has a certain flexibility, thereby avoiding rigid deformation and improving the overall reliability during use. At the same time, it can also provide good protection for the neck portion and avoid failure during use.

[0014] 3. The neck portion of the present application is formed by setting an arc-shaped notch. This method has limited impact on the load-bearing capacity of the structure itself, but can improve the impact resistance of the connection and ensure structural stability.
