[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a reinforced steel structure at the joint of a steel structure, comprising a vertical beam 1, a horizontal beam 3 is fixedly connected to the top of the vertical beam 1, a placement plate 4 is fixedly connected to the inner side of the vertical beam 1, a worm 5 is rotatably connected to the front side of the vertical beam 1, and the rear end of the worm 5 passes through the vertical beam 1, and the left and right sides of the top of the placement plate 4 are rotatably connected to a rotating rod 6, a worm wheel 7 is fixedly connected to the outer side of the rotating rod 6, and the two worm wheels 7 are respectively meshed with the left and right sides of the worm 5, and the top of the rotating rod 6 is fixedly connected to a driving bevel gear 8, and the left and right sides of the inside of the vertical beam 1 are rotatably connected to a bidirectional screw rod 9, and the middle part of the outer side of the bidirectional screw rod 9 is fixedly connected to a driven bevel gear 10, and the two driven bevel gears 10 are respectively meshed with the corresponding driving bevel gear 8. The front and rear sides of the outer wall of the bidirectional screw rod 9 are both threadedly connected with movable blocks 11, and the top of the movable block 11 is fixedly connected with a bent rod 12. The left and right sides of the vertical beam 1 are both provided with a first U-shaped plate 13, and one end of a plurality of bent rods 12 respectively penetrates the front and rear sides of the corresponding first U-shaped plate 13. The left and right sides of the bottom of the cross beam 3 are slidably connected with a second U-shaped plate 15, and an adjustment mechanism 2 is provided on one side of the first U-shaped plate 13. The rear end of the worm 5 is rotatably connected to the inner rear side of the vertical beam 1. The plurality of first U-shaped plates 13 and the second U-shaped plates 15 are symmetrically distributed, and a plurality of plug holes 17 are equidistantly provided on the front and rear sides of the cross beam 3. A plug rod 16 is provided on the front side of the second U-shaped plate 15, and one end of the plug rod 16 respectively penetrates the corresponding second U-shaped plate 15 and the plug hole 17;

[0032] Specifically, when the worm 5 is rotated, the worm wheels 7 on both sides that are tightly meshed with it will rotate accordingly. This meshing relationship ensures the smooth transmission of power and reduces energy loss. As the worm wheel 7 rotates, the rotating rod 6 will also rotate, thereby driving the active bevel gear 8 to rotate. At the same time, the driven bevel gear 10 on the two-way screw 9 will also start to rotate due to the meshing relationship with the active bevel gear 8. As the driven bevel gear 10 rotates, the two-way screw 9 also starts to rotate. At this time, the curved rod 12 on the movable block 11 starts to move to both sides under the drive of the two-way screw 9 until the curved rod 12 is completely inserted into the hole reserved on the first U-shaped plate 13. Subsequently, the insertion rod 16 is inserted into the corresponding insertion hole 17 to complete the installation of the reinforcing steel. The installation and disassembly process of this method is relatively simple, which not only reduces the workload of the staff, but also improves the work efficiency.

[0033] Reference Figure 1 and Figure 4 The adjusting mechanism 2 includes a first rotating shaft 201, and the two first rotating shafts 201 are respectively rotatably connected to the adjacent sides of the first U-shaped plate 13, and the bottom of the second U-shaped plate 15 is rotatably connected to the second rotating shaft 202, and one side of the first rotating shaft 201 is fixedly connected to a hollow column 203, and one side of the hollow column 203 is equidistantly provided with a plurality of limiting holes 204, and one side of the second rotating shaft 202 is fixedly connected to a movable rod 205, and the upper side of the movable rod 205 is provided with a hole 206, and the inner bottom of the hole 206 is fixedly connected to a spring 207, and the top of the spring 207 is fixedly connected to a limiting rod 208, and the two limiting rods 208 are respectively plugged into the corresponding limiting holes 204, and the two movable rods 205 are respectively slidably connected to the inside of the corresponding hollow column 203, and the sizes of the two movable rods 205 match the internal sizes of the corresponding hollow column 203.

[0034] Specifically, when it is necessary to adjust the usable length of the steel structure, the staff only needs to press the limit rod 208. At this time, the spring 207 will be squeezed to drive the limit rod 208 to disengage from the limit hole 204 and enter the hole 206. The first rotating shaft 201 and the second rotating shaft 202 will rotate accordingly, and the movable rod 205 will also move in the hollow column 203. When the second U-shaped plate 15 moves to the corresponding position, the spring 207 will release the squeezed force and drive the limit rod 208 to pop out from the corresponding limit hole 204, thereby further improving the stability of the joint of the steel structure.

[0035] Reference Figure 2 and Figure 3 , a plurality of slide bars 14 are fixedly connected to the left and right sides of the interior of the vertical beam 1, and the left and right sides of the plurality of movable blocks 11 are slidably connected to the outer walls of the corresponding slide bars 14 respectively;

[0036] Specifically, the moving track of the moving block 11 can be limited by the sliding rod 14, so that the moving block 11 can move more smoothly.

[0037] Reference Figure 1 , the front and rear ends of the left and right tops of the vertical beam 1 are fixedly connected with reinforcing ribs 18;

[0038] Specifically, the overall stability between the cross beam 3 and the vertical beam 1 can be further increased by the reinforcing ribs 18 .

[0039] Working principle: When using the reinforced steel structure, first put the first U-shaped plate 13 into the corresponding position, and then rotate the worm 5. At this time, the worm wheels 7 on both sides will rotate due to the meshing with the worm 5, and the rotating rod 6 will rotate accordingly, thereby driving the active bevel gear 8 to rotate. The driven bevel gear 10 on the two-way screw rod 9 will rotate due to the meshing with the active bevel gear 8, thereby driving the two-way screw rod 9 to rotate. At this time, the curved rod 12 on the movable block 11 will move to both sides until it is inserted into the hole reserved on the first U-shaped plate 13, and then the second U-shaped plate 15 is moved to the corresponding position, and then the insertion rod 16 is inserted into the corresponding insertion hole 17 to complete the installation of the reinforced steel. The installation and disassembly of the reinforced steel structure is relatively simple, thereby reducing the workload of the staff, meeting the needs of the user, and when installing the reinforced steel structure, First observe the size of the beam 3, then remove the insertion rod 16 and move the second U-shaped plate 15, so that the second U-shaped plate 15 is moved to the middle position on both sides of the beam 3, which can make the beam 3 placed more stably. While moving the second U-shaped plate 15, press the limit rod 208, and the spring 207 will be squeezed to drive the limit rod 208 to disengage from the limit hole 204 and enter the hole 206. At this time, the first rotating shaft 201 and the second rotating shaft 202 will rotate accordingly, and the movable rod 205 will also move in the hollow column 203. The use length of the reinforced steel structure can be adjusted according to the actual length of the beam 3. After the second U-shaped plate 15 moves to the corresponding position, the spring 207 will release the squeezed force and drive the limit rod 208 to pop out of the corresponding limit hole 204, thereby further improving the stability of the steel structure connection.
