[0037] See also Figures 1 to 7 , the present invention provides a technical solution:

[0038] Example 1

[0039] A prefabricated lattice column scissors brace for a subway station comprises a lattice column, a tensioning column 8 and a scissors brace 11.

[0040] Specifically, the lattice column includes a lattice vertical beam 1 and a lattice cross beam 2. The lattice column uses a structure commonly used in the prior art and is composed of four lattice vertical beams 1 and multiple lattice cross beams 2 welded together. A first hanging plate 3 and a second hanging plate 4 are respectively suspended on both sides of the lattice column. A strip hole 5 and an avoidance hole 6 are opened in the middle of the second hanging plate 4. The avoidance hole 6 is located at the upper end of the strip hole 5 and has an inner diameter larger than the strip hole 5. A notch groove 7 is opened at the lower end of the first hanging plate 3.

[0041] Secondly, the tensioning column 8 is located between the first hanging plate 3 and the second hanging plate 4. Both ends of the tensioning column 8 are fixedly connected with threaded rods 9. The two threaded rods 9 are movable through the strip hole 5 and the notch groove 7 respectively. The ends of the threaded rods 9 are screwed with tensioning nuts 10. Figure 3 、 Figure 4 and Figure 5 As shown, the threaded rod 9 at one end of the tensioning column 8 passes through the avoidance hole 6 and then moves downward to be hung on the lower end of the strip hole 5. The threaded rod 9 at the other end of the tensioning column 8 can be placed into the inner cavity of the notch groove 7 from bottom to top, and then the two ends of the tensioning column 8 can be tightened and fixed to the first hanging plate 3 and the second hanging plate 4 respectively by tightening the tensioning nut 10;

[0042] Furthermore, the cross brace 11 is located in the middle of the outer side of the second hanging plate 4. A connecting hole 12 is provided at the end of the cross brace 11. The end of the cross brace 11 is fixedly connected to the end of a threaded rod 9 through a fastening nut 13. The cross brace 11 is supported by the threaded rod 9. The cross brace 11 applies a downward force to the threaded rod 9 at one end of the tension column 8, causing the tension column 8 to rotate according to the lever principle with the inner wall of the lower end of the strip-shaped hole 5 as the fulcrum. The threaded rod 9 at the other end of the tension column 8 is stuck in the inner cavity of the notch groove 7 from bottom to top. The first hanging plate 3 can position the other end of the tension column 8 to prevent the tension column 8 from rotating, thereby ensuring that the cross brace 11 remains stable in position under the action of gravity after installation. And between the middle parts of the two cross braces 11, they are fixedly connected through a reinforcement mechanism 22 to further reinforce the stability of the two cross braces 11.

[0043] Embodiment Two

[0044] On the basis of Embodiment One, in order to further support the cross brace 11, the present application further has a support frame 14 provided between the cross brace 11 and the second hanging plate 4. The support frame 14 is in an "L" shape. The support frame 14 is padded under the end of the cross brace 11 from bottom to top. A boss 15 is fixedly connected to the middle part of the outer side wall of the second hanging plate 4. The boss 15 is arranged in a "U" shape with the opening facing downwards. The thickness of the boss 15 is the same as the thickness of the vertical surface of the support frame 14. The support frame 14 is used to further support the end of the cross brace 11. The settings of the support frame 14 and the boss 15 can also ensure that the fitting surface between the second hanging plate 4 and the cross brace 11 remains flush.

[0045] Embodiment Three

[0046] On the basis of Embodiment Two, in order to hang the support frame 14, the present application further has a connecting plate 16 fixedly connected to the upper end of the support frame 14. The thickness of the connecting plate 16 is smaller than the thickness of the boss 15. A hanging hole 17 is provided on the surface of the connecting plate 16. The connecting plate 16 is sleeved outside the threaded rod 9 through the hanging hole 17. The connecting plate 16 is located between the tension nut 10 and the second hanging plate 4. The settings of the connecting plate 16 and the hanging hole 17 are used to hang the support frame 14 on the threaded rod 9.

[0047] Embodiment Four

[0048] On the basis of Embodiment Three, in order to prevent the second hanging plate 4 from sliding along the length direction of the lattice cross beam 2, the present application further has positioning baffles 18 fixedly connected to both the upper and lower ends inside the second hanging plate 4. The positioning baffles 18 are perpendicular to the second hanging plate 4. Chamfers are provided at both ends of the positioning baffles 18. The two end faces of the positioning baffles 18 respectively abut against the sides of two adjacent lattice vertical beams 1. The settings of the positioning baffles 18 are used to prevent the second hanging plate 4 from sliding along the length direction of the lattice cross beam 2.

[0049] Embodiment Five

[0050] On the basis of Example 4, in order to define the hanging connection of the first hanging plate 3 and the second hanging plate 4 in detail, the present application also has a limiting card 19 fixedly connected to the inner wall of the first hanging plate 3, and the limiting card 19 is arranged in an "L" shape. The limiting card 19 is buckled from bottom to top on the outside of the lattice beam 2. Since the tensioning column 8 will rotate under the gravity of the scissors strut 11, the first hanging plate 3 will be subjected to an upward force. At this time, the limiting card 19 is stuck on the lower side of the lattice beam 2, and the position of the first hanging plate 3 can be positioned, thereby preventing the tensioning column 8 from rotating and tilting. The upper end of the second hanging plate 4 is arranged in an "η" shape and is buckled from top to bottom on the outside of the lattice beam 2 to ensure that the second hanging plate 4 can be suspended and connected to the lattice beam 2 under the action of gravity.

[0051] Example 6

[0052] On the basis of Example 5, in order to prevent the first hanging plate 3 and the second hanging plate 4 from tilting, the present application also has a limit baffle 20 fixedly connected to the inner side of the lower end of the first hanging plate 3, the limit baffle 20 is pressed on the outer side of the lattice vertical beam 1, and the lower end of the second hanging plate 4 is placed on the outer side of the lattice horizontal beam 2, which is used to prevent the first hanging plate 3 and the second hanging plate 4 from being too close to each other during the process of tightening the first hanging plate 3 and the second hanging plate 4 by the tightening nut 10, causing the first hanging plate 3 and the second hanging plate 4 to tilt.

[0053] Example 7

[0054] On the basis of Example 6, in order to prevent the tensioning column 8 from separating from the first hanging plate 3, the present application also has an anti-slip block 21 fixedly connected to the lower end of the outer wall of the first hanging plate 3, and the anti-slip block 21 is flush with the height position of the middle part of the notch groove 7. The anti-slip block 21 is set to limit the tensioning nut 10 on the outside of the first hanging plate 3 to prevent the tensioning nut 10 from moving downward and causing the tensioning column 8 to separate from the first hanging plate 3.

[0055] Example 8

[0056] On the basis of Example 7, in order to tighten and fix the two scissors struts 11, the reinforcement mechanism 22 of the present application includes a tightening screw 23. An adjustment slot 27 is opened through the middle of the scissors strut 11. The end of the tightening screw 23 passes through the inner cavity of the adjustment slot 27 and is screwed with a connecting nut 24. The connecting nut 24 is pressed on the outer side of the scissors strut 11 to tighten and fix the two scissors struts 11.

[0057] Embodiment 9

[0058] On the basis of the eighth embodiment, in order to mutually restrict the two cross braces 11, the present application further has "U"-shaped clamping plates 25 sleeved on both ends of the tensioning screw rod 23. The "U"-shaped clamping plates 25 are buckled on the inner sides of the cross braces 11. Positioning nuts 26 are screwed on both ends of the tensioning screw rod 23, and the positioning nuts 26 press on the surfaces of the "U"-shaped clamping plates 25. The "U"-shaped clamping plates 25 are used to clamp the cross braces 11, ensuring mutual restraint between the two cross braces 11, thereby improving the connection stability between the two cross braces 11.

[0059] A construction process for the fabricated lattice column cross braces of a subway station according to the above, specifically includes the following steps:

[0060] Step 1: Hang the second hanging plate 4 from top to bottom on the lattice cross beam 2 on one side of the lattice column. Pass the tensioning column 8 through the lattice column from the other side of the lattice column, and make the threaded rod 9 pass through the strip hole 5. Then tighten the tensioning nut 10 to press the second hanging plate 4, ensuring that the tensioning column 8 is connected to the second hanging plate 4;

[0061] Step 2: Set the first hanging plate 3 on the other side of the lattice column, and ensure that the threaded rod 9 at the other end of the tensioning column 8 passes through the inner cavity of the notch groove 7. Then use the tensioning nut 10 to press the first hanging plate 3, ensuring that the tensioning column 8 is connected to the first hanging plate 3;

[0062] Step 3: Hang the support frame 14 on the threaded rod 9 through the hanging hole 17 and fit it with the outer side wall of the second hanging plate 4. Then fixedly connect the end of the cross brace 11 to the end of the threaded rod 9 through the fastening nut 13. At this time, the cross brace 11 can be hung on the outside of the lattice column, and the support frame 14 is padded under the lower surface of the end of the cross brace 11 from bottom to top to further support the cross brace 11;

[0063] Step 4: Buckle two "U"-shaped clamping plates 25 on the middles of the two cross braces 11 respectively. Then tighten the two cross braces 11 in the middle through the tensioning screw rod 23 and the connecting nut 24. Then tighten the positioning nut 26 to press the "U"-shaped clamping plate 25 and the cross brace 11 to fit tightly, and the two cross braces 11 can be tensioned and strengthened.
