Description

Technical Field

[0001] The invention relates to the technical field of steelmaking plants, and in particular to a large-scale staggered-span steelmaking plant structure and a construction method. Background Art

[0002] Large-scale staggered-span steelmaking plants are a specially designed industrial building, mainly used for steelmaking production. The design of the 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 span design of the plant. This design enables the plant structure to adapt to different process flows and equipment requirements, thereby improving the utilization efficiency of space.

[0003] CN211619768U discloses a stable combined steel beam structure for a steel plant. The steel plant structure cooperates with the steel beam through the support plates, support columns, double-headed screws, etc. to support the steel beam, improve the stability of the steel beam, and facilitate the movement of the overhead crane. The support rods, connecting rods, and fixed screws are arranged to cooperate with the steel beam to further support and reinforce the steel beam, avoid shaking of the steel beam, and enhance the stability of the steel beam.

[0004] However, when connecting the steel beams in the above-mentioned factory building structure, bolts and nuts are used. Since the equipment inside the steelmaking plant will generate large vibrations when in use, the factory building is in a vibration environment for a long time, which can easily cause the bolts and nuts to loosen, causing the bolts to fall off from the steel beams, reducing the connection stability between the steel beams and the overall structural stability of the factory building.

This solves the problem that when the plant structure is used to connect the steel beams, bolts and nuts are used for cooperation, and since the internal equipment of the steelmaking plant will generate large vibrations when in use, the plant is in a vibrating environment for a long time, which makes it easy for the bolts and nuts to loosen.

[0035] Example 1

[0036] See also Figure 1-5 , a large staggered span steelmaking plant structure and construction method, comprising a plurality of support components arranged front and back, each support component comprising a plurality of beams and columns 1 arranged at intervals, a top crossbeam 2 being placed on the tops of two adjacent beams and columns 1, a reinforcement frame 3 being fixed on the upper ends of the outer walls of the plurality of beams and columns 1, and a reinforcement beam 4 being fixed between the plurality of reinforcement frames 3 in front and back;

[0037] A transverse plate 5 is fixed on the top of the plurality of beams 1, a mounting bolt 6 is threadedly passed through the top transverse beam 2 and the transverse plate 5, a limiting nut 7 is threadedly sleeved on the lower side of the threaded end of the mounting bolt 6, the limiting nut 7 is in contact with the bottom of the transverse plate 5, and a mounting hole is opened inside the top transverse beam 2 to match the mounting bolt 6;

[0038] A vertical plate 8 is fixed on the top of the horizontal plate 5, and connecting grooves are opened on both sides of the vertical plate 8. A vertical rod 9 is fixed on the inner wall of the connecting groove. The cross-section of the vertical rod 9 is rectangular. A limit block 10 is sleeved on the outer side of the vertical rod 9. A limit pressure plate 11 is fixed on the outer wall of the limit block 10, and the limit pressure plate 11 is arranged on the top of the mounting bolt 6.

[0039] When constructing the factory building structure, firstly, multiple beams 1 are spaced apart at the factory building installation position, and the top cross beam 2 is laid. At this time, the beams 1 and the top cross beam 2 can be connected by installing bolts 6 and limit nuts 7. Then, the limit block 10 can be inserted into the connection groove, and the position of the limit block 10 can be determined under the setting of the vertical rod 9. At this time, the limit block 10 can drive the limit pressure plate 11 to be set on the top of the installation bolt 6, and try to avoid the bolts from falling off from the top cross beam 2 in a vibration environment, so as to ensure the connection stability between the steel structures of the factory building. After multiple supporting components are set, the reinforcing beam 4 can be reinforced, and the ceiling can be set on the top of multiple top cross beams 2 to complete the setting of the factory building structure.

[0040] Example 2

[0041] Embodiment 2 is based on Embodiment 1 in order to make the setting position of the limiting pressure plate 11 fixed, as shown in FIG. Figure 2-3 As shown, the limit block 10 is set in a U shape, and a card-connecting positioning mechanism is provided between the limit block 10 and the vertical rod 9. The card-connecting positioning mechanism includes two symmetrically arranged card blocks 12, and the two card blocks 12 are wedge-shaped blocks. The interior of the limit block 10 is hollow, and the two card blocks 12 are respectively slidably arranged on both sides of the inner wall of the limit block 10. Both sides of the inner wall of the limit block 10 are provided with through holes 21 for matching the card blocks 12. A spring 13 is fixedly provided between one side of the card block 12 located inside the limit block 10 and the inner wall of the limit block 10. Two symmetrically arranged sliding grooves are provided at both ends of the inner wall of the limit block 10. A slide plate 14 is fixedly penetrated through the inner wall of the card block 12, and the two ends of the slide plate 14 are respectively slidably arranged in two adjacent sliding grooves.

[0042] When the limit block 10 is inserted into the connecting groove, since the block 12 is a wedge-shaped block and one side is arranged with an inclined surface, when the inclined surface of the block 12 contacts the vertical rod 9, the block 12 is pushed and squeezes the spring 13. In this process, the cooperation of the slide plate 14 and the slide groove can provide stable limiting support for the movement of the block 12. When the limit block 10 contacts the inner wall of the connecting groove, the block 12 rebounds and is arranged on the outside of the vertical rod 9 under the elastic force recovery of the spring 13. At this time, the position of the limit block 10 and the limit pressure plate 11 can be determined by cooperating with the connecting groove, thereby completing the top limit of the mounting bolt 6.

[0043] Example 3

[0044] Embodiment 3 is based on Embodiment 1-2, in order to be able to promptly remove the limit block 10 and reset the mounting bolt 6 when the top crossbeam 2 has an installation deviation, as shown in FIG. Figure 3-5 As shown, a rotating rod 15 is rotatably provided on the inner wall of the limit block 10, and a push plate 16 is provided on the rod wall fixing sleeve of the rotating rod 15. Connecting plates 17 are provided on both sides of the push plate 16 in contact and cooperation. The two connecting plates 17 are respectively fixedly connected with the two clamping blocks 12, and the push plate 16 is arranged in a cam shape. The two connecting plates 17 are arranged symmetrically with the center, and the sides close to each other are arranged in an inclined surface. A rotating wheel 18 is provided on the rod wall fixing sleeve of the rotating rod 15, and a torsion spring 19 is provided on the rod wall sleeve of the rotating rod 15. The two ends of the torsion spring 19 are respectively fixedly connected with the rotating rod 15 and the inner wall of the limit block 10, and a rotating hole 20 is opened on the outer wall of the limit block 10 to cooperate with the rotation of the rotating wheel 18. The side wall of the rotating wheel 18 passes through the rotating hole 20 and extends to the outside.

[0045] When the installation position of the top crossbeam 2 deviates, the rotating wheel 18 can be pushed, so that the rotating wheel 18 drives the rotating rod 15 to rotate, and 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, so that the connecting plates 16 are pushed and drive the clamping block 12 to move. At this time, the clamping block 12 can retract into the limit block 10. At this time, the limit block 10 can be pulled out of the connecting groove and separated from the mounting bolts 6, and the mounting bolts 6 can be quickly disassembled, ensuring the convenience of connection and disassembly between the steel structures of the factory building and improving the construction efficiency of the steelmaking plant.
