Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a force conversion node structure of a steel structure corridor system. Background Art

[0002] With the development of economy, super high-rise connected steel structures are widely used. High-altitude corridors with connected structures are generally made of steel structures. Due to the large span of the corridor, the deformation of the corridor floor beams will generate very large tension and pressure on the main structures of the towers on both sides, which has a great influence on the stress of the main structure. Therefore, the columns and beams of the main structure are increased accordingly, resulting in an increase in the cost of the main structure.

[0003] The utility model patent with announcement number CN205276461U is named as a hinged and rigid force conversion node of a steel structure corridor, which includes an upper steel column, a lower steel column, a corridor upper chord steel beam and a diagonal web member. The end of the corridor upper chord steel beam is connected to the upper steel column, and a diagonal web member is provided at the connection between the two. A lower steel column is provided below the upper steel column, and its characteristics are: it also includes a semicircular steel shaft and a corresponding shaft support, the semicircular steel shaft is arranged on the web plate of the bottom surface of the upper steel column, the shaft support corresponding to the semicircular steel shaft is arranged on the web plate of the top surface of the lower steel column, the upper steel column is arranged on the lower steel column, and the semicircular steel shaft on the web plate of the bottom surface of the upper steel column is located in the shaft support on the web plate of the top surface of the lower steel column; the upper steel column and the lower steel column realize rotation through the semicircular steel shaft and the shaft support. The upper chord steel beam of the corridor in this scheme is connected to the upper steel column, and the upper steel column and the lower steel column are connected to the shaft support through a semicircular steel shaft and can rotate. However, the upper chord steel beam of the corridor is only connected to the upper steel column through a diagonal web member. Therefore, when the upper steel column and the lower steel column rotate, the connection strength between the upper chord steel beam of the corridor and the upper steel column will be difficult to ensure, which will cause adverse effects. Therefore, a force conversion node structure of a steel structure corridor system is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a force conversion node structure of a steel structure corridor system, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a force conversion node structure of a steel structure corridor system, including a column, a steel beam connected to the column is provided on the outside of the column, a connecting frame connected to the column is provided on the outside of the column, and the steel beam is installed in the column through the connecting frame and the steel beam can move slightly. The steel beam is installed in the column through the connecting frame, and can have a certain degree of rotational freedom through the setting of the connecting frame, which helps to reduce the stress and deformation generated by the structure when it is subjected to force. And through the setting of the connecting frame, a certain connection strength can be provided, so that the steel beam and the column can jointly bear a larger load.

[0008] Furthermore, the connecting frame is a rib plate, the rib plate is installed at the top end of the column, and the steel beam is installed on the rib plate.

[0009] Furthermore, the lower end of the steel beam is provided with a semicircular steel bar connected to the steel beam, and the rib plate is provided with a slide groove adapted to the semicircular steel bar, and the steel beam can be moved slightly along the slide groove in the rib plate through the semicircular steel bar, and the steel beam and the rib plate can be rotated through the semicircular steel bar. The function of the semicircular steel bar is to hinge the steel beam and the column, thereby having a certain degree of rotation freedom.

[0010] Furthermore, the rib is provided with a connecting screw that can be inserted into the steel beam, and the rib is provided with a limit block for limiting the connecting screw, and the limit block can be slightly displaced along the steel beam, and graphite powder is provided between the semicircular steel bar and the slide groove. By setting structures such as the connecting screw and the limit block, it can not only cooperate with a certain rotation of the semicircular steel bar, but also ensure the connection strength between the steel beam and the rib. Graphite powder has good properties such as high temperature resistance, electrical conductivity, thermal conductivity, lubrication and chemical stability, which makes it have many possible uses in construction. For example, graphite powder can be used as a refractory material to improve the high temperature resistance of building materials. In addition, the lubricating properties of graphite powder can also be used to reduce friction and wear of construction machinery during operation and increase the service life of the equipment.

[0011] Furthermore, a through groove is provided in the steel beam, a protrusion that can be embedded in the through groove is provided at the bottom of the limit block, and a limit bolt that can be inserted into the connecting screw is provided on the outside of the limit block. The coordinated arrangement of the connecting screw, the limit block, the through groove and the limit bolt enables the connecting screw to drive the limit block to move longitudinally when the steel beam is rotated through the semicircular steel column, thereby ensuring a certain connection strength during the rotation process. When the steel beam and the semicircular steel column slide slightly along the slide groove, the limit block and the protrusion can move along the through groove, and the connection strength can still be ensured. Therefore, it can not only reduce the stress and deformation generated by the structure when it is subjected to force, but also enable the column and the steel beam to jointly withstand a larger load.

[0012] Furthermore, the cross-sectional shape of the protrusion is semicircular, and the diameter of the protrusion with the semicircular cross-sectional shape is smaller than the diameter of the through groove.

[0013] Furthermore, the column is provided with an I-shaped steel frame connected to the column, the rib plate is provided with a fastening bolt that can be inserted into the column, the column is provided with a fastening nut ring that is compatible with the fastening bolt, the column is provided with a locking bolt that can be inserted into the I-shaped steel frame and compatible with the fastening bolt, and the outside of the locking bolt is provided with an auxiliary bolt that can be inserted into the fastening bolt.

[0014] Furthermore, the column is provided with a sliding block A that moves along the horizontal sliding groove of the column, the sliding block A is provided with an arc rod connected to the sliding block A, the steel beam is provided with a sliding block B that moves along the longitudinal sliding groove of the steel beam, and the arc rod is installed in the sliding block B in the steel beam. Through the coordinated arrangement of the sliding block A, the arc rod, the sliding block B and other structures, it can not only prevent the steel beam from rotating through the semicircular steel bar and other structures, but also help to strengthen the connection strength between the steel beam and the column to ensure its safety.

[0015] Furthermore, a longitudinal strip through groove is provided in the steel beam, and the arc rod can be displaced along the longitudinal strip through groove, and the arc rod is connected to the sliding block B through a connecting ball.

[0016] Compared with the prior art, the force conversion node structure of the steel structure corridor system not only improves the rotation ability of the node and ensures that the corridor can be deformed freely, but also further improves the overall connection strength, thereby ensuring its safety.
