A node connection device for steel structures of high-rise buildings

Abstract

This invention discloses a node connection device for high-rise building steel structures, relating to the field of steel structure connection technology. It includes a main beam and secondary beams. The main beam consists of a main vertical plate and a pair of main horizontal plates, and the secondary beam consists of a secondary vertical plate and a pair of secondary horizontal plates. A vertical tie plate is fixedly connected between the two secondary horizontal plates, and a horizontal tie plate is fixedly connected between the two main horizontal plates. It also includes a reinforcement component and a detection component. This invention achieves multi-directional reinforcement of the main and secondary beams of the steel structure, improving the overall structural strength. It solves the problem that the connection methods between the main and secondary beams in the searched patents have poor stability and firmness. Existing methods typically use high-strength bolts for fixing, but because the main and secondary beams are subjected to lateral, longitudinal, and vertical forces, the bolts need to withstand forces of different angles and magnitudes, which can easily lead to metal fatigue and deformation of the bolts, reducing the connection strength between the main and secondary beams.

Description

Technical Field

[0001] This invention relates to the field of steel structure connection technology, and in particular to a node connection device for high-rise building steel structures. Background Technology

[0002] Steel structure materials are widely used in the modern construction industry. They are used as supports in many high-rise buildings, and the stability of the steel structure connections is often an important guarantee for ensuring the stability of the overall structural frame.

[0003] Patent document CN218562638U discloses a seismic-resistant steel structure for high-rise buildings, including a first main board, a first connecting plate fixedly connected to one outer wall of the first main board, a first slot formed on one outer wall of the first main board, a second main board disposed on one side of the first main board, a second connecting plate fixedly connected to one outer wall of the second main board, a second slot formed on one outer wall of the second main board, the outer wall of the first connecting plate engaging with the inner wall of the second slot, and the outer wall of the second connecting plate engaging with the inner wall of the first slot.

[0004] However, the above invention has the following shortcomings: the stability and firmness of the connection between the main beam and the secondary beam are poor. The existing method usually uses high-strength bolts for fixing. Since the main beam and the secondary beam are subjected to lateral, longitudinal and vertical forces, the bolts need to withstand forces of different angles and magnitudes. Therefore, the bolts are prone to metal fatigue and deformation, which reduces the connection strength between the main beam and the secondary beam. Thus, there are certain limitations. Summary of the Invention

[0005] The purpose of this invention is to provide a node connection device for steel structures of high-rise buildings to solve the problems mentioned in the background art. By setting multiple bolts in different directions, the steel structure is connected and reinforced. At the same time, the connection points of the steel structure can be detected in real time by setting multiple sensors in different directions, which facilitates the maintenance of the connection points of the steel structure by the staff.

[0006] The technical solution of the present invention is: a node connection device for steel structure of high-rise building, including a main beam and a secondary beam. The main beam is composed of a main vertical plate and a pair of main horizontal plates. The secondary beam is composed of a secondary vertical plate and a pair of secondary horizontal plates. A vertical tie plate is fixedly connected between the two secondary horizontal plates. A horizontal tie plate is fixedly connected between the two main horizontal plates. The device also includes a reinforcement component and a detection component.

[0007] The reinforcement components include a double-force connecting frame and a single-force connecting frame disposed between the main vertical plate and the secondary vertical plate;

[0008] The detection component includes a power pipe fixedly installed on the main horizontal plate.

[0009] Preferably, the double-force connecting frame has multiple inner longitudinal tension holes on both sides, and the vertical tension support plate and the main vertical plate have outer longitudinal tension holes corresponding to the inner longitudinal tension holes. The double-force connecting frame is connected to the vertical tension support plate and the main vertical plate by longitudinal bolts threaded through the inner and outer longitudinal tension holes.

[0010] Preferably, the double-force connecting frame has multiple inner vertical pull holes on both the upper and lower sides, and the main horizontal plate and the secondary horizontal plate have outer vertical pull holes corresponding to the inner vertical pull holes. The double-force connecting frame is connected to the main horizontal plate and the secondary horizontal plate by vertical bolts threaded through the inner vertical pull holes and the outer vertical pull holes.

[0011] Preferably, the single-force connecting frame has multiple inner horizontal pull holes on both sides, and the horizontal pull plate and the secondary vertical plate have outer horizontal pull holes corresponding to the inner horizontal pull holes. The single-force connecting frame is connected to the horizontal pull plate and the secondary vertical plate by a horizontal bolt threaded through the inner and outer horizontal pull holes.

[0012] Preferably, a pair of vertical compression sensors and a pair of horizontal compression sensors are symmetrically fixedly installed on the inner peripheral wall of the power pipe, and a longitudinal tension sensor is fixedly installed on the inner side wall of the power pipe.

[0013] Preferably, an alarm is fixedly installed on one side of the power pipe, and the vertical compression sensor, horizontal compression sensor and longitudinal tension sensor are all electrically connected to the alarm.

[0014] Preferably, a contact rod is fixedly installed on the surface of the secondary horizontal plate, one end of the contact rod is movably installed inside the power pipe, and a connecting rod is fixedly installed between the contact rod and the longitudinal tension sensor.

[0015] This invention provides an improved node connection device for high-rise building steel structures, which has the following improvements and advantages compared with the prior art:

[0016] Firstly, this invention utilizes a double-force connecting frame and vertical tie plate, with longitudinal bolts used to fix the steel structure longitudinally through the outer and inner longitudinal tie holes, and vertical bolts used to fix the steel structure vertically through the outer and inner vertical tie holes. The longitudinal and vertical bolts effectively fix the steel structure connections longitudinally and vertically. In addition, by using a single-force connecting frame and transverse tie plate, with transverse bolts used through the inner and outer transverse tie holes, the steel structure connections are fixed laterally, thus achieving multi-directional fixing of the steel structure and improving the connection strength between the main and secondary beams.

[0017] Secondly, this invention uses power pipes and vertical compression sensors, horizontal compression sensors, and longitudinal tension sensors. When different degrees of deformation and movement occur at the steel structure connection, the contact rod will touch the sensor, thereby triggering an alarm and reminding staff to reinforce and maintain the steel structure connection.

[0029] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides an improved node connection device for high-rise building steel structures. The technical solution of this invention is as follows:

[0031] like Figures 1 to 8 As shown, this embodiment of the invention provides a node connection device for a high-rise building steel structure, including a main beam and a secondary beam. The main beam consists of a main vertical plate 1 and a pair of main horizontal plates 101, and the secondary beam consists of a secondary vertical plate 2 and a pair of secondary horizontal plates 201. A vertical tie plate 3 is fixedly connected between the two secondary horizontal plates 201, and a horizontal tie plate 9 is fixedly connected between the two main horizontal plates 101. The device also includes a reinforcement component and a detection component. The vertical tie plate 3 and the horizontal tie plate 9 provide certain support for the main beam and the secondary beam, and at the same time provide a certain foundation for the subsequent installation of the reinforcement component. The detection component can detect the connection of the steel structure to prevent the steel structure from deforming or shifting due to the instability of the reinforcement over a long period of time, thereby causing certain safety hazards.

[0032] The reinforcement components include a double-force connecting frame 5 and a single-force connecting frame 11 set between the main vertical plate 1 and the secondary vertical plate 2. The double-force connecting frame 5 and the single-force connecting frame 11 can play a certain role in reinforcing the connection between the main beam and the secondary beam at the steel structure connection.

[0033] The detection component includes a power pipe 17 fixedly installed on the main horizontal plate 101. The power pipe 17 can provide support for the other components of the detection component, ensuring that the detection component can work normally.

[0034] Furthermore, multiple inner longitudinal tension holes 6 are provided on both sides of the double-force connecting frame 5, and outer longitudinal tension holes 4 corresponding to the inner longitudinal tension holes 6 are provided on the vertical support plate 3 and the main vertical plate 1. The double-force connecting frame 5 is connected to the vertical support plate 3 and the main vertical plate 1 by longitudinal bolts 13 through the inner longitudinal tension holes 6 and the outer longitudinal tension holes 4. Through the inner longitudinal tension holes 6 and the outer longitudinal tension holes 4, the longitudinal bolts 13 can stably and firmly connect the double-force connecting frame 5 to the vertical support plate 3 and the main vertical plate 1, thereby achieving the effect of longitudinal reinforcement of the steel structure.

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

[0036] Furthermore, multiple inner horizontal tension holes 12 are provided on both sides of the single-force connecting frame 11, and outer horizontal tension holes 10 corresponding to the inner horizontal tension holes 12 are provided on the horizontal tension support plate 9 and the secondary horizontal plate 2. The single-force connecting frame 11 is connected to the horizontal tension support plate 9 and the secondary horizontal plate 201 by horizontal bolts 15 through the inner horizontal tension holes 12 and the outer horizontal tension holes 10. By using the inner horizontal tension holes 12 and the outer horizontal tension holes 10, the single-force connecting frame 11 is fixedly connected to the horizontal tension support plate 9 and the secondary horizontal plate 201 by the horizontal bolts 15, thereby achieving the effect of lateral reinforcement at the steel structure connection and further improving the structural strength of the joint at the steel structure connection.

[0037] As a further embodiment of the present invention, a pair of vertical compression sensors 18 and a pair of horizontal compression sensors 19 are symmetrically fixedly installed on the inner peripheral wall of the power pipe 17, and a longitudinal tension sensor 20 is fixedly installed on the inner side wall of the power pipe 17. By setting the vertical compression sensors 18, horizontal compression sensors 19 and longitudinal tension sensor 20, multi-directional detection of the nodes at the steel structure connection can be achieved, enabling workers to reinforce and maintain the steel structure connection in a timely manner.

[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 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 contact rod 16 is fixedly installed on the surface of the secondary horizontal plate 201. One end of the contact rod 16 is movably installed inside the power pipe 17. A connecting rod 22 is fixedly installed between the contact rod 16 and the longitudinal tension sensor 20. When longitudinal loosening occurs between the secondary horizontal plate 201 and the main horizontal plate 101, the contact rod 16 pulls the longitudinal tension sensor 20 through the connecting rod 22 to trigger the alarm 21, which facilitates the detection of longitudinal changes in the steel structure.

[0040] The specific working principle is as follows: 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, respectively. Then, the vertical tie plate 3 and the horizontal tie plate 9 are fixedly installed. Multiple sets of external vertical tie holes 7 and internal vertical tie holes 8 are opened. The double-force connecting frame 5 is fixedly connected to the vertical tie plate 3 and the main vertical plate 1 using vertical bolts 14 to achieve vertical reinforcement of the steel structure connection. Similarly, horizontal bolts 15 and 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 joint at the steel structure connection. In addition, by setting power pipes 17, vertical compression sensors 18, horizontal compression sensors 19 and longitudinal tension sensors 20 on the surface of the steel structure at two points, the sensors are triggered by the contact rod 16. The contact rod 16 can move with the changes at the steel structure connection, thereby triggering the corresponding sensors and triggering the alarm 21 to work, thus reminding the staff to reinforce and maintain the steel structure connection, improving the stability and safety of the steel structure connection.
