Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure bridge support node. Background Technology

[0002] Connecting bridges, serving as links between two or more high-rise buildings, have become an indispensable component of connected and adjacent structures. When the rigidity of the connecting bridge itself is weak, even a rigid connection cannot effectively coordinate the deformation of the two towers. In such cases, a sliding connection should be considered. A sliding connection can involve one end of the connecting bridge being hinged to the tower and the other end being slidably connected, or both ends being fitted with sliding supports. To ensure the normal use of the connecting bridge, engineering projects often install connecting bridge supports at both ends. Firstly, the connecting bridge supports act as a force transmission medium, transferring the load to the structural members on both sides, ensuring the overall structural safety and stability of the connecting bridge. Secondly, the connecting bridge supports can absorb the deformation of the connecting bridge and the structural members on both sides during use, preventing excessive deformation from damaging the overall structure of the connecting bridge. Finally, the connecting bridge supports have vibration damping and sound insulation effects, effectively mitigating vibration and noise during use. Currently, ball joint supports are commonly used as the sliding supports at the ends of steel connecting bridges. Ball joint bearings require the purchase of prefabricated bearings, which has a long procurement cycle and high cost. In addition, the ball joint bearing and the support below it are relatively tall, which reduces the net height of the building floors. Utility Model Content

[0003] Due to the aforementioned deficiencies in existing technologies, this utility model provides a steel structure bridge support node with a relatively simple structure, short processing and manufacturing cycle, and low construction cost. While ensuring structural safety, it can maximize the building's clear height.

[0004] To achieve the above objectives, this utility model provides a steel structure bridge support node, comprising:

[0005] The corbel support is welded to the main structural steel beam, and the top is provided with the first high-strength bolt hole;

[0006] The flange plate extends horizontally outward from both sides of the lower flange at the end of the main steel beam of the connecting bridge, and has a second high-strength bolt hole.

[0007] The web plate connecting plate is vertically disposed on both sides of the end of the main steel beam of the connecting bridge, and is connected to the main steel beam of the connecting bridge through the third high-strength bolt hole and high-strength bolt;

[0008] High-strength bolts pass through the first and second high-strength bolt holes to connect the corbel support and the flange plate; the web plate connecting plate is welded to the main structural steel beam.

[0009] The bridge support joints meet both structural stress requirements and expansion / contraction requirements. Furthermore, the bridge undergoes repeated expansion and contraction over long periods, posing a risk of breakage to the high-strength bolts. The bridge support joints ensure the structural safety of the bridge even if the bolts break.

[0010] Furthermore, the first high-strength bolt hole is an oblong hole, the second high-strength bolt hole is a circular hole, and the third high-strength bolt hole is an oblong hole.

[0011] Furthermore, the end of the main steel beam of the connecting bridge also includes a cover plate covering the web connecting plate; the cover plate is horizontally butt-welded to the flange plate of the main steel beam of the connecting bridge and corner-welded to the top surface of the web of the main steel beam of the connecting bridge.

[0012] Furthermore, the ends of the main steel beam of the connecting bridge are box-shaped sections with gradually decreasing height, and a first vertical stiffening plate is provided on the inner side.

[0013] Furthermore, the first vertical stiffening plate is provided at both the normal height of the box-shaped section and at the opening where the height is reduced.

[0014] Furthermore, the corbel support includes a top plate and a second vertical stiffening plate; a first high-strength bolt hole is formed on the top plate.

[0015] Furthermore, a third vertical stiffening plate is provided on the inner side of the main structural steel beam; the third vertical stiffening plate is at least located on the same plane as the second vertical stiffening plate.

[0016] Furthermore, the third vertical stiffening plate is also provided on both sides of the same plane as the second vertical stiffening plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) Compared with traditional finished supports, this utility model has the advantages of simple manufacturing, low cost and short cycle.

[0019] (2) Compared with traditional finished supports, this utility model reduces the node height and can provide the maximum building height.

[0020] (3) Compared with the simple elongated hole high-strength bolt connection node, the added lower support of this utility model can provide vertical support in the event of high-strength bolt failure, thus ensuring structural safety. Attached Figure Description

[0033] Example

[0034] This embodiment provides a steel structure bridge support node. See the bridge construction details below. Figure 1 and attached Figure 2 It consists of two parts: the connecting bridge section and the main structure section; the connecting bridge section consists of the main steel beam 1 and the connecting cable 2; the support section consists of the main structure steel beam 3 as the support steel beam and the corbel support 4.

[0035] See Figures 3 to 8 The support nodes include the corbel support 4, the flange plate 12, and the web connecting plate 5.

[0036] The bracket 4 is welded to the main structural steel beam 3, and the top is provided with the first high-strength bolt hole 13;

[0037] The flange plate 12 extends horizontally outward to both sides of the lower flange of the end of the main steel beam 1 of the connecting bridge, and the second high-strength bolt holes are opened there;

[0038] The web plate connecting plate 5 is vertically installed on both sides of the end of the main steel beam 1 of the connecting bridge, and is connected to the main steel beam 1 of the connecting bridge through the third high-strength bolt hole and high-strength bolt.

[0039] High-strength bolts pass through the first high-strength bolt hole 13 and the second high-strength bolt hole to connect the bracket support 4 and the flange plate 12; the web plate connecting plate 5 is welded to the main structural steel beam 3.

[0040] The connecting bridge support nodes are connected to the main structure support via high-strength bolts through horizontally extending flange plates at the lower flange ends of the connecting bridge steel beams; and vertically extending bolt plates with elongated holes at the ends of the steel beams are welded to the main structure steel beams. This achieves horizontal expansion and contraction deformation and vertical support for the connecting bridge, and the lower support avoids the structural safety risks caused by the wear and breakage of the high-strength bolts. The connecting bridge support nodes also ensure the structural safety of the connecting bridge in the event of bolt breakage. If the high-strength bolts break, the web plate connecting plate 5 at the ends of the steel beams will restrict the horizontal displacement of the main steel beam 1 of the connecting bridge, ensuring that the connecting bridge steel beam is located above the support; in addition, the corbel support below the main structure steel beam 3 will provide vertical support, and the connecting bridge cables 2 on both sides will also provide vertical and horizontal support.

[0041] The installation process of the connecting bridge support node is as follows: After the main steel beam 1 of the connecting bridge is installed in place, high-strength bolts are installed on the corbel support 4 and initially tightened; then the web plate connecting plate 5 is installed and the high-strength bolts are initially tightened; finally, the web plate connecting plate 5 is welded to the main structural steel beam 3. After the high-strength bolts and the main structural steel beam 3 are welded, anti-corrosion paint repair is carried out in the node area to complete the construction of the connecting bridge node.

[0042] As a preferred technical solution, the first high-strength bolt hole is an oblong hole, the second high-strength bolt hole is a circular hole, and the third high-strength bolt hole is an oblong hole. Thus, the first and third high-strength bolt holes allow for fine-tuning of the high-strength bolt position. The second high-strength bolt hole prevents the high-strength bolt from shaking.

[0043] As a preferred technical solution, the end of the main steel beam 1 of the connecting bridge also includes a cover plate 11 covering the web connecting plate 5; the cover plate 11 is horizontally butt-welded to the flange plate of the main steel beam (1) of the connecting bridge, and corner-welded to the top surface of the web plate of the main steel beam (1) of the connecting bridge. During node installation, the cover plate 11 is welded after the anti-corrosion paint repair is completed to further protect the node from rainwater erosion.

[0044] As a preferred technical solution, the ends of the main steel beam 1 of the connecting bridge are box-shaped sections with gradually decreasing height, and a first vertical stiffening plate 10 is provided on the inner side. Furthermore, the first vertical stiffening plate 10 is provided at both the normal height of the box-shaped section and at the reduced height opening. This improves the bearing capacity at the joint.

[0045] As a preferred technical solution, the corbel support 4 includes a top plate 6 and a second vertical stiffening plate 9; a first high-strength bolt hole is formed on the top plate 6.

[0046] As a preferred technical solution, a third vertical stiffening plate 8 is provided on the inner side of the main structural steel beam 3; the third vertical stiffening plate 8 is at least located on the same plane as the second vertical stiffening plate 9. In this way, the bearing capacity at the joint can be improved.

[0047] As a preferred technical solution, the third vertical stiffening plate 8 is also provided on both sides of the same plane as the second vertical stiffening plate 9. This can improve the bearing capacity at the joint.

[0048] As can be seen from the above construction structure, the steel bridge of this utility model has the characteristics of simple manufacturing, low cost and short cycle, while reducing the node height and maximizing the building's net height; the added lower support can provide vertical support in the event of high-strength bolt failure, ensuring structural safety.

[0049] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a conventional manner within the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this utility model using the disclosed methods and techniques, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. This does not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
