[0030] The present invention provides a node connection device for a high-rise building steel structure through improvement. The technical solution of the present invention is:

[0031] like Figures 1 to 8 As shown, an embodiment of the present invention provides a node connection device for a high-rise building steel structure, including a main beam and a secondary beam, wherein the main beam is composed of a main vertical plate 1 and a pair of main horizontal plates 101, and the secondary beam is composed of a secondary vertical plate 2 and a pair of secondary horizontal plates 201. A vertical support plate 3 is fixedly connected between the two secondary horizontal plates 201, and a horizontal support plate 9 is fixedly connected between the two main horizontal plates 101. It also includes a reinforcement component and a detection component. The vertical support plate 3 and the horizontal support plate 9 are provided to support the main beam and the secondary beam to a certain extent, and at the same time provide a certain basis for the subsequent arrangement of the reinforcement component. The detection component can be used to detect the connection of the steel structure to prevent the reinforcement from being unreliable after a long time, which may cause the steel structure to deform or deviate, thereby bringing certain safety hazards.

[0032] The reinforcement component includes a double force connection frame 5 and a single force connection frame 11 arranged between the main vertical plate 1 and the secondary vertical plate 2. The double force connection frame 5 and the single force connection frame 11 can play a certain role in reinforcing the connection between the main beam and the secondary beam at the connection of the steel structure.

[0033] The detection component includes an electric power tube 17 fixedly mounted on the main horizontal plate 101. The set electric power tube 17 can provide support for the remaining components of the detection component and can provide guarantee for the normal operation of the detection component.

[0034] Furthermore, a plurality of inner longitudinal pulling holes 6 are opened on both sides of the double force connecting frame 5, and outer longitudinal pulling holes 4 corresponding to the inner longitudinal pulling holes 6 are opened on the vertical pulling support plate 3 and the main vertical plate 1. The double force connecting frame 5 is threadedly connected with the vertical pulling support plate 3 and the main vertical plate 1 through the inner longitudinal pulling holes 6 and the outer longitudinal pulling holes 4. The longitudinal bolts 13 can be used to stably and firmly connect the double force connecting frame 5 with the vertical pulling support plate 3 and the main vertical plate 1 through the opened inner longitudinal pulling holes 6 and the outer longitudinal pulling holes 4, thereby achieving the effect of longitudinal reinforcement of the steel structure.

[0035] Furthermore, multiple inner vertical pull holes 8 are provided on the upper and lower sides of the double-force connecting frame 5, and outer vertical pull holes 7 corresponding to the inner vertical pull holes 8 are provided on the main horizontal plate 101 and the secondary horizontal plate 201. The double-force connecting frame 5 is threadedly connected with the main horizontal plate 101 and the secondary vertical plate 2 through the inner vertical pull holes 8 and the outer vertical pull holes 7. By utilizing the provided inner vertical pull holes 8 and the outer vertical pull holes 7, the double-force connecting frame 5 is fixedly connected with the main horizontal plate 101 and the secondary vertical plate 2 through the vertical bolts 14, thereby achieving the vertical reinforcement effect of the steel structure connection.

[0036] Furthermore, multiple inner horizontal pulling holes 12 are opened on both sides of the single-force connecting frame 11, and outer horizontal pulling holes 10 corresponding to the inner horizontal pulling holes 12 are opened on the horizontal pulling support plate 9 and the secondary vertical plate 2. The single-force connecting frame 11 is threadedly connected with the horizontal pulling support plate 9 and the secondary horizontal plate 201 through the inner horizontal pulling holes 12 and the outer horizontal pulling holes 10. The single-force connecting frame 11 is fixedly connected with the horizontal pulling support plate 9 and the secondary horizontal plate 201 by the horizontal bolts 15 by utilizing the opened inner horizontal pulling holes 12 and the outer horizontal pulling holes 10, thereby achieving the effect of transverse reinforcement of the steel structure connection, thereby further improving the structural strength of the node at the steel structure connection.

[0037] As a further solution of the present invention, a pair of vertical extrusion sensors 18 and a pair of transverse extrusion sensors 19 are symmetrically fixedly installed on the inner wall of the power pipe 17, and a longitudinal tension sensor 20 is fixedly installed on the inner wall of the power pipe 17. The vertical extrusion sensors 18, transverse extrusion sensors 19 and longitudinal tension sensors 20 can realize multi-directional detection of the nodes at the connection of the steel structure, so that the staff can reinforce and maintain the steel structure connection in time.

[0038] An alarm 21 is fixedly installed on one side of the power pipe 17. The vertical compression sensor 18, the horizontal compression sensor 19 and the longitudinal tension sensor 20 are all electrically connected to the alarm 21. Through the electrical connection, it can be ensured that the alarm 21 can be triggered in time when multiple sensors are triggered, thereby achieving the purpose of reminding the staff.

[0039] Furthermore, a touch rod 16 is fixedly installed on the surface of the secondary cross plate 201, and one end of the touch rod 16 is movably installed inside the power tube 17. A connecting rod 22 is fixedly installed between the touch rod 16 and the longitudinal tension sensor 20. When longitudinal looseness occurs between the secondary cross plate 201 and the main cross plate 101, the touch rod 16 pulls the longitudinal tension sensor 20 through the connecting rod 22 to cause the alarm 21 to sound an alarm, thereby facilitating the detection of longitudinal changes in the steel structure.

[0040] Specific working principle: first, the double-force connecting frame 5 and the single-force connecting frame 11 are fixedly installed between the main vertical plate 1 and the secondary vertical plate 2, and then the vertical tension support plate 3 and the horizontal tension support plate 9 are fixedly installed, and multiple groups of outer vertical tension holes 7 and inner vertical tension holes 8 are opened. The double-force connecting frame 5 is fixedly connected with the vertical tension support plate 3 and the main vertical plate 1 by vertical bolts 14 to achieve vertical reinforcement of the steel structure connection. Similarly, the horizontal bolts 15 and the longitudinal bolts 13 are fixedly installed in sequence to achieve multi-directional reinforcement of the steel structure, thereby greatly improving the structural strength of the nodes at the steel structure connection. In addition, by arranging power pipes 17 and vertical extrusion sensors 18 and horizontal extrusion sensors 19 and longitudinal tension sensors 20 on the surfaces of the steel structure at two places, the touch rod 16 is triggered, and the touch rod 16 can move with the changes in the steel structure connection, thereby triggering the corresponding sensor, and then triggering the alarm 21 to work, thereby reminding the staff to reinforce and maintain the steel structure connection and improve the stability and safety of the steel structure connection.
