Description

Technical Field

[0001] This utility model relates to the field of beam-column connection technology, specifically a quick-assembly beam-column connection node. Background Technology

[0002] Beam-column connection refers to the secure connection of beams and columns in a building structure to transfer loads and maintain the overall stability of the structure. Beam-column connection is an important component of steel structures, and its connection method directly affects the load-bearing capacity and safety of the structure. Therefore, a quick-assembly beam-column connection node is needed.

[0003] When connecting beams and columns, operators often use welding. However, welding reduces their strength, stiffness, and energy dissipation capacity. Furthermore, the limited methods of fixing beams and columns may result in poor stability and reduced practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-assembly beam-column connection node to solve the problem mentioned in the background art, where operators often use welding when connecting beams and columns. However, welding reduces strength, stiffness, and energy consumption, and the single method of fixing beams and columns may result in poor stability and reduced practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly beam-column connection node, comprising a base column and a connecting column. The top of the base column has a connecting groove, and a beam is movably installed inside the connecting groove. Both ends of the top of the base column have slots, and both ends of the bottom of the connecting column have fixedly installed blocks that are compatible with the slots. Both ends of the base column and the connecting column have movably installed square plates. Both sides of the beam have pin holes, and one end of each square plate has a movably installed connecting plate. One end of each connecting plate has a fixedly installed limiting pin. One end of the limiting pin passes through the square plate and the base column and extends to the back of the square plate, and the outer surface of the limiting pin is movably connected to the inner surface of the pin hole.

[0006] Preferably, a lead screw is fixedly installed at one end of each limiting pin, a sleeve rod is movably sleeved on the surface of the lead screw, and a nut is threaded onto the surface of each limiting pin.

[0007] Preferably, one end of each square plate is rotatably fitted with a fastening bolt, and one end of the fastening bolt passes through the bottom column and the connecting column and extends into the interior of the bottom column and the connecting column.

[0008] Preferably, a positioning plate is movably installed between one side of the connecting column and the top of the beam. A positioning bolt is rotatably installed on one side and the bottom of the inner side of the positioning plate. The bottom of the positioning bolt located at the bottom of the inner side of the positioning plate penetrates the positioning plate and extends into the interior of the beam. One side of the positioning bolt located on one side of the inner side of the positioning plate penetrates the positioning plate and extends into the interior of the connecting column.

[0009] Preferably, a mounting bracket is movably installed between one side of the base column and one end of the beam. A mounting bolt is rotatably installed on one end and one side of the mounting bracket. One end of the mounting bolt located at one end of the mounting bracket passes through the mounting bracket and extends into the interior of the beam, and one side of the mounting bolt located on one side of the mounting bracket passes through the mounting bracket and extends into the interior of the base column.

[0010] Preferably, both sides of the base column are fixedly installed with support frames located below the beam, and the interior of each support frame is fixedly installed with reinforcing plates at equal intervals.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This rapid-assembly beam-column connection node allows for quick connection during daily use. The operator places the beam inside the connection slot and then slides the connecting column. The connecting column then moves a locking block, placing it inside the slot and connecting the base column. Square plates are then placed at both ends of the base column and connecting column, respectively. The fastening bolts are then screwed into the base column and connecting column. Simultaneously, the connecting plate is slid, causing a limiting pin to slide through the square plate and base column and into a pin hole. The limiting pin then moves a threaded rod until one end of the connecting plate is positioned at the front end of the square plate of the base column. Finally, a sleeve is fitted onto the threaded rod and secured with a nut, thus connecting the beam to the base column and connecting column. This method allows for rapid connection and avoids welding.

[0013] This type of quick-assembly beam-column connection node, during daily use, involves the operator placing the positioning plate between one side of the connecting column and the top of the beam, then rotating the positioning bolts, and subsequently screwing the positioning bolts into the positioning plate and the interior of the beam and the connecting column, respectively. Simultaneously, the mounting bracket is placed between one side of the base column and one end of the beam, and the mounting bolts are rotated, subsequently screwing the mounting bracket into the interior of the beam and the interior of the base column, respectively. This process re-fixes the base column, beam, and connecting column, reducing loosening and improving stability. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a quick-assembly beam-column connection node, including a base column 1 and a connecting column 5. The top of the base column 1 has a connecting groove 2, and a beam 3 is movably installed inside the connecting groove 2. The connecting groove 2 and the beam 3 are compatible, and the beam 3 can be placed inside the connecting groove 2. Both ends of the top of the base column 1 have slots 4, and both ends of the bottom of the connecting column 5 have fixedly installed blocks 6, which are compatible with the slots 4. When the connecting column 5 slides, it will cause the blocks 6 to slide, thus placing the blocks 6 inside the slots 4, thereby connecting the base column 1 and the connecting column 5. Both ends of the base column 1 and the connecting column 5 are movably installed with square plates 7. Pin holes 8 are opened on both sides of the inside of the beam 3, and the pin holes 8 are compatible with limiting pins 10. The beam 3 can be positioned through the pin holes 8 and the limiting pins 10. One end of the square plate 7 is movable. A connecting plate 9 is installed, and a limit pin 10 is fixedly installed at one end of the connecting plate 9. When the connecting plate 9 slides, it will drive the limit pin 10 to pass through the square plate 7 and the bottom column 1 and be placed inside the pin hole 8, thereby fixing the beam 3. One end of the limit pin 10 passes through the square plate 7 and the bottom column 1 and extends to the back of the square plate 7. The outer surface of the limit pin 10 is movably connected to the inner surface of the pin hole 8. A screw rod 11 is fixedly installed at one end of the limit pin 10. When the limit pin 10 slides, it will drive the screw rod 11 to slide. There are two limit pins 10, and the two limit pins 10 are the same size. A sleeve rod 12 is movably sleeved on the surface of the screw rod 11, and a nut 13 is threaded on the surface of the limit pin 10. Due to the design of the sleeve rod 12 and the nut 13, the screw rod 11 can be fixed, thereby fixing the limit pin 10.

[0021] One end of each square plate 7 is rotatably fitted with a fastening bolt 14, one end of which passes through the bottom column 1 and the connecting column 5 and extends into the interior of the bottom column 1 and the connecting column 5, respectively. By rotating the fastening bolt 14 and screwing it into the interior of the bottom column 1 and the connecting column 5, the bottom column 1 and the connecting column 5 can be connected. A positioning plate 15 is movably installed between one side of the connecting column 5 and the top of the beam 3. A positioning bolt 16 is rotatably installed on one side and the bottom of the positioning plate 15. The bottom of the positioning bolt 16 located at the bottom of the positioning plate 15 passes through the positioning plate 15 and extends into the interior of the beam 3, and one side of the positioning bolt 16 located on one side of the positioning plate 15 passes through the positioning plate 15 and extends into the interior of the connecting column 5. By rotating the positioning bolt 16 and screwing it into the interior of the positioning plate 15 and the beam 3 and the interior of the positioning plate 15 and the connecting column 5, the bottom column 1, the beam 3 and the connecting column 5 can be connected. Four mounting brackets 17 are movably installed between one side of the base column 1 and one end of the beam 3. The four mounting brackets 17 are the same size. Mounting bolts 18 are rotatably installed on one end and one side of the inside of the mounting bracket 17. One end of the mounting bolt 18 located at one end of the inside of the mounting bracket 17 passes through the mounting bracket 17 and extends into the inside of the beam 3. The other side of the mounting bolt 18 located at one side of the inside of the mounting bracket 17 passes through the mounting bracket 17 and extends into the inside of the base column 1. By rotating the mounting bolts 18 and screwing them into the inside of the mounting bracket 17 and the beam 3 and the base column 1 respectively, the beam 3 and the base column 1 can be connected. Support brackets 19 located below the beam 3 are fixedly installed on both sides of the base column 1. Reinforcing plates 20 are fixedly installed at equal intervals inside the support brackets 19. The design of the support brackets 19 and the reinforcing plates 20 can support the beam 3, thereby making it more stable.

[0022] Working principle: First, the operator places beam 3 inside the connecting groove 2, then slides connecting column 5. Connecting column 5 then causes locking block 6 to slide and be placed inside the groove 4, connecting bottom column 1 and connecting column 5. At this point, square plate 7 is placed at both ends of bottom column 1 and connecting column 5. Then, the fastening bolt 14 is rotated and screwed into the bottom column 1 and connecting column 5 respectively. Simultaneously, connecting plate 9 is slid, causing limiting pin 10 to slide and pass through square plate 7, bottom column 1, and into pin hole 8. Limiting pin 10 then causes lead screw 11 to slide until one end of connecting plate 9 is in front of one end of square plate 7 of bottom column 1. Then, sleeve rod 12 is fitted onto the surface of lead screw 11 and positioned using nut 13, thus connecting beam 3 between base column 1 and connecting column 5. Next, positioning plate 15 is placed between one side of connecting column 5 and the top of beam 3, and positioning bolt 16 is rotated. Then, positioning bolt 16 is screwed into the interior of positioning plate 15 and beam 3, and into the interior of positioning plate 15 and connecting column 5, respectively. At the same time, mounting bracket 17 is placed between one side of base column 1 and one end of the interior of beam 3, and mounting bolt 18 is rotated. Then, mounting bolt 18 is screwed into the interior of mounting bracket 17 and beam 3, and into the interior of mounting bracket 17 and base column 1, thus fixing and connecting base column 1, beam 3 and connecting column 5 again.
