Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steelmaking plant, in particular to a large-scale staggered-span continuous-row steelmaking plant structure and construction method. BACKGROUND

[0002] The large-scale staggered-span continuous-row steelmaking plant is a specially designed industrial building, mainly used for steelmaking production. The design of this plant structure takes into account the special conditions such as high temperature and heavy load in the steelmaking production process, while pursuing efficient space utilization and flexibility. The staggered span refers to the asymmetric or staggered arrangement of the plant in the span design. This design enables the plant structure to adapt to different process flows and equipment requirements, improving the efficiency of space utilization.

[0003] CN211619768U is a stable combined steel beam structure for steelmaking plant. The steelmaking plant structure is supported by the support plate, support column, double-end screw and steel beam, which can support the steel beam, improve the stability of the steel beam, facilitate the walking of the overhead crane, and further support and reinforce the steel beam by setting the support rod, connecting rod and fixed screw, avoiding the shaking of the steel beam and enhancing the stability of the steel beam.

[0004] However, the above plant structure adopts bolts and nuts for connection between steel beams. Due to the large vibration of the internal equipment of the steelmaking plant during use, the plant is in a vibrating environment for a long time, which can cause loosening between the bolts and nuts, and the bolts can fall off from the steel beam, reducing the connection stability between the steel beams and the overall structural stability of the plant.

[0037] The top of each beam column 1 is fixedly provided with a horizontal plate 5, the mounting bolt 6 is threadedly provided between the top beam 2 and the horizontal plate 5, the threaded end of the mounting bolt 6 is threadedly sleeved with a limit nut 7, the limit nut 7 is in contact with the bottom of the horizontal plate 5, and the inside of the top beam 2 is provided with a mounting hole connected with the mounting bolt 6;

[0038] A vertical plate 8 is fixedly installed on the top of the horizontal plate 5. A connecting groove is opened on both sides of the vertical plate 8. A vertical rod 9 is fixedly installed on the inner wall of the connecting groove. The cross-section of the vertical rod 9 is rectangular. A limiting block 10 is sleeved on the outer side of the vertical rod 9. A limiting pressure plate 11 is fixedly installed on the outer wall of the limiting block 10. The limiting pressure plate 11 is located on the top of the mounting bolt 6.

[0039] When constructing the factory structure, multiple beams and columns 1 are first placed at intervals at the factory installation location, and the top crossbeams 2 are laid. At this time, the beams and columns 1 and the top crossbeams 2 can be connected by installation bolts 6 and limit nuts 7. Then, the limit blocks 10 can be inserted into the connecting groove, and the position of the limit blocks 10 is determined with the setting of the vertical rods 9. At this time, the limit blocks 10 can drive the limit pressure plates 11 to be set on the top of the installation bolts 6, so as to avoid the bolts falling off from the inside of the top crossbeams 2 under vibration environment and ensure the connection stability between the steel structures of the factory. After multiple support components are set, the reinforcing beams 4 can be reinforced, and a canopy can be set on the top of multiple top crossbeams 2, thereby completing the setting of the factory structure.

[0040] Example 2

[0041] Example 2, based on Example 1, aims to fix the position of the limiting pressure plate 11, such as... Figures 2-3 As shown, the limiting block 10 is U-shaped. A locking and positioning mechanism is provided between the limiting block 10 and the vertical rod 9. The locking and positioning mechanism includes two symmetrically arranged locking blocks 12, both of which are wedge-shaped blocks. The interior of the limiting block 10 is hollow. The two locking blocks 12 are slidably disposed on both sides of the inner wall of the limiting block 10. Both sides of the inner wall of the limiting block 10 are provided with through holes 21 for the locking blocks 12 to pass through. A spring 13 is fixedly provided between the side of the locking block 12 located inside the limiting block 10 and the inner wall of the limiting block 10. Two symmetrically arranged sliding grooves are provided at both ends of the inner wall of the limiting block 10. A sliding plate 14 is fixedly disposed on the inner wall of the locking block 12. The two ends of the sliding plate 14 are slidably disposed in the two adjacent sliding grooves.

[0042] When the limiting block 10 is inserted into the connecting groove, since the locking block 12 is a wedge-shaped block with one side set at an angle, when the angle of the locking block 12 contacts the vertical rod 9, the locking block 12 is pushed and squeezes the spring 13. During this process, the movement of the locking block 12 can be stably limited and supported by the cooperation of the sliding plate 14 and the sliding groove. When the limiting block 10 contacts the inner wall of the connecting groove, the locking block 12 rebounds under the elastic force of the spring 13 and is set on the outside of the vertical rod 9. At this time, the position of the limiting block 10 and the limiting pressure plate 11 can be determined by the connecting groove, thereby completing the top limiting of the mounting bolt 6.

[0043] Example 3

[0044] Example 3 is based on examples 1-2 in order to be able to timely remove the limiting block 10 when the top beam 2 installation deviation occurs, and the installation bolt 6 is reset, as shown in Figures 3-5 The inner wall of the limiting block 10 is rotatably provided with a rotating rod 15, the rod wall of the rotating rod 15 is fixedly sleeved with a push plate 16, the two sides of the push plate 16 are in contact and fit with a connecting plate 17, the two connecting plates 17 are respectively fixedly connected with the two clamping blocks 12, the push plate 16 is provided in a cam shape, the two connecting plates 17 are provided in a central symmetry, and the side close to each other is provided in an inclined surface, the rod wall of the rotating rod 15 is fixedly sleeved with a rotating wheel 18, the rod wall of the rotating rod 15 is sleeved with a torsion spring 19, the two ends of the torsion spring 19 are respectively fixedly connected with the rotating rod 15 and the inner wall of the limiting block 10, the outer wall of the limiting block 10 is provided with a rotating hole 20 matched with the rotation of the rotating wheel 18, the side wall of the rotating wheel 18 extends to the outside through the rotating hole 20.

[0045] When the installation position of the top beam 2 deviates, the rotating wheel 18 can be pushed to make the rotating wheel 18 drive the rotating rod 15 to rotate, so that the rotating rod 15 drives the push plate 17 to rotate, and the two ends of the push plate 17 cooperate with the inclined surfaces of the two connecting plates 16 to make the connecting plate 16 be pushed to drive the clamping block 12 to move, at this time the clamping block 12 can retract into the limiting block 10, at this time the limiting block 10 can be pulled out from the connecting groove and separated from the installation bolt 6, and the installation bolt 6 can be quickly disassembled to ensure the convenience of connection and disassembly between the steel structure of the factory building, and improve the construction efficiency of the steel factory building.
