[0002] The safety and reliability of building structures are important barriers to ensure personal safety and property safety. The beam-column connection nodes are important components of building structures, and their stress performance will directly affect the safety and reliability of the entire building structure.

[0003] For example, a beam-column connection node with Chinese publication number CN114108807A comprises: a first square steel tube concrete column and a second square steel tube concrete column butted up and down; a connecting tube, which is sleeved on the above-mentioned butt joint; two H-shaped steel beams, which are respectively arranged on opposite sides of the connecting tube, a first L-shaped connecting piece is provided between the upper flange of the H-shaped steel beam and the connecting tube, a second L-shaped connecting piece is provided between the lower flange of the H-shaped steel beam and the connecting tube, a detachable energy-absorbing component is provided on the flange of the H-shaped steel beam, and an anchor plate is provided on the web of the H-shaped steel beam; a first prestressed steel strand is passed through the connecting tube and the first square steel tube concrete column, and its two ends are respectively anchored on two anchor plates located on different sides of the connecting tube; a second prestressed steel strand is passed through the connecting tube and the second square steel tube concrete column, and its two ends are respectively anchored on two anchor plates located on different sides of the connecting tube.

[0004] The above-mentioned prior art arranges energy-absorbing connectors between beams and columns as a connection method between the two, so that the node is far away from the axis of the supporting column. This not only increases the building volume but also makes the supporting force of the load-bearing node mainly concentrated at the connection outside the supporting column, which easily leads to poor node support effect and insufficient stability.

[0005] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes.

Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Depend on Figures 1 to 5As shown, an embodiment of the utility model provides a socket-and-spigot box-type side column concrete 10 steel beam node, comprising a box-type column 1 and an I-beam 2 installed on one side of the box-type column 1 through a connecting assembly 3; the connecting assembly 3 comprises two flange connecting plates 4 and two welded steel plates 5, the welded steel plates 5 are parallel to the flange parts of the I-beam 2 and are chamfered and welded on the inner wall of the box-type column 1, the flange connecting plates 4 pass through the inner wall of the box-type column 1 and are fixed to the welded steel plates 5 by bolts, the flange connecting plates 4 are located at the outer side of the box-type column 1 and are fixed to the flange of the I-beam 2 by bolts; further, the connecting assembly 3 also comprises two web connecting plates 6 and a reinforcing steel plate 7, the two web connecting plates 6 pass through the inner wall of the box-type column 1 and are symmetrically installed on both sides of the web of the I-beam 2 by bolts, the reinforcing steel plate 7 is installed between the two web connecting plates 6 by bolts, and the reinforcing steel plate 7 is located inside the box-type column 1. Among them, the socket-type box column 1 is provided with an opening suitable for the flange connecting plate 4 and the web connecting plate 6 to pass through at the position where the I-beam 2 is connected. The end of the installed I-beam 2 is against the side wall of the box column 1, so that the force node between the beam and the column is closer to the center of the box column 1 as the main support, and at the same time, the connection node is partially extended into the box column 1 with space, making full use of the spatial structure of the box column 1. The force of the node part directly acts on the axial direction of the box column 1 structure, making the building structure more compact and more stable. Preferably, the welded steel plate 5 is penetrated by a through hole 8 for pouring concrete 10; the lower end of the welded steel plate 5 extends from the end of the through hole 8 to the outer side end around the axially downward to form an extension. After the installation of the beams, columns and connecting components 3 is completed, concrete 10 is poured at the nodes, so that a steel tube concrete 10 structure is formed in the box column 1, the bearing capacity of the component can be greatly improved, the connection performance is further improved, and a prism-shaped space is formed in the middle part by setting an inclined extension portion. After the concrete 10 is poured, it is vibrated again, so that the internal air bubbles can leave the node along the inclined inner wall, avoid being trapped under the welded steel plate 5 at the node, and improve the uniformity and quality of the concrete 10 after forming.

[0025] like Figure 3 Preferably, the side end of the extension portion is provided with a through groove 11 suitable for the web connecting plate 6 to pass through. When the web connecting plate 6 contacts the extension portion, the through groove 11 is provided to avoid interference between the two. If there is no contact during design, the welding steel plate 5 with the through groove 11 can be omitted, and the top of the through groove 11 can also be slightly inclined to reduce interference with the movement of bubbles.

[0026] like Figure 4Among them, because the welding steel plate 5 must be kept parallel to the flange part of the I-beam 2, the welding steel plate 5 located below has a flange connecting plate 4 located below the welding steel plate 5, and the side end of the extension part is provided with a groove 12 suitable for inserting the flange connecting plate 4, which can avoid the conflict between the components. During splicing, the bolts can pass from the upper end of the welding steel plate 5 downward through the flange connecting plate 4 and the groove 12 for reinforced connection assembly.

[0027] As a preferred embodiment, the welded steel plate 5 is a low yield point steel plate with a yield point less than or equal to Q100, so that the welded steel plate 5 serves as a stable connecting member in normal state. When an earthquake occurs and the node is subjected to external force, resulting in structural damage to the concrete 10, the circular through hole 8 in the middle can be used as a compression space to yield and deform, thereby producing energy dissipation effect to a certain extent.

[0028] Furthermore, the through hole 8 is arranged at the axial center position of the welded steel plate 5. And the cross section of the box-type column 1 is a regular rectangular shape to ensure that the force between the structures can be evenly transmitted when subjected to external force.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
