Description

Technical Field

[0001] This invention relates to the field of factory building structure technology, specifically to a large-scale double-span steelmaking factory building structure and its construction method. Background Technology

[0002] Traditional large-scale, double-span steelmaking plant structures often employ pre-embedded steel sections, with tie rods used to stabilize the sections and form a frame structure. Walls are then constructed between the steel sections, and corrugated steel sheets are used for roofing. The walls are constructed by gradually stacking hollow bricks or directly riveting corrugated steel sheets onto the steel sections. The problems with this approach are: poor structural stability between the steel sections; long construction time and high cost using hollow bricks; low strength and poor insulation with corrugated steel sheets; long construction period for pre-embedded steel sections; lack of versatility; and low construction precision.

[0003] CN109083456A describes a prefabricated factory building structure, comprising a base, wall panels, lintels, and a roof. Multiple bases are assembled into a parallel matrix within a foundation pit. The wall panels slide against the bases and are secured with anchors and adapters. However, this design is cumbersome and time-consuming. If a central wall panel is damaged, the outer wall panels must be removed first before the damaged panel can be replaced. After replacement, the outer wall panels must be reinstalled, making the process tedious and labor-intensive. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a large-scale double-span steelmaking plant structure and construction method that enables rapid disassembly and replacement of damaged wall panels, greatly improving the efficiency of wall panel replacement. This solves the problem in existing prefabricated plant structures where, if a central wall panel is damaged, the outer wall panel must be disassembled first before the damaged wall panel can be replaced. After replacement, the outer wall panel must be reinstalled, a cumbersome, time-consuming, and labor-intensive process that significantly impacts the efficiency of wall panel replacement.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a large-scale double-span steelmaking plant structure and construction method, comprising a base and a roof, wherein multiple bases are arranged sequentially from front to back on both sides below the roof, multiple adjacent bases are abutting each other, and support plates are fixedly installed on both sides of the multiple bases; mounting holes are fixedly installed on the lower surfaces of both sides of the roof at positions corresponding to the multiple support plates, and support rods are inserted into the inner sides of the multiple mounting holes; the lower ends of the multiple support rods are fixedly connected to the corresponding support plates; the lower surfaces of both ends of the roof are... Each of the bases is fixedly provided with a first mounting plate, and each of the multiple bases is fixedly provided with a second mounting plate. A wall plate is provided between the first mounting plate and the multiple second mounting plates. A connecting plate is slidably provided at both ends of the outer side of the wall plate. The connecting plates on both sides abut against the corresponding first and second mounting plates. A plug rod is fixedly provided on the opposite side of the connecting plates on both sides. A plug hole is provided on the surface of the first and second mounting plates at the position corresponding to the plug rod. One end of each of the multiple plug rods is plugged into the corresponding plug hole.

[0008] Side plates are fixedly installed at both ends of the opposite side of the wall panels on both sides. Slide grooves are opened at both ends of the side plates. Movable plates are slidably fitted inside the two slide grooves. One end of the movable plate is fixedly connected to the corresponding connecting plate.

[0009] A rotating rod is rotatably installed in the middle of the side opposite to the two wall panels, and the rod wall is provided with a transmission mechanism that drives the two connecting plates to move.

[0010] Preferably, the transmission mechanism includes a rotating block and push rods. The rotating block is rotatably sleeved on the wall of the rotating rod. Two push rods are disposed on the front sides of both ends of the rotating block. One end of each push rod is rotatably connected to one end of the rotating block through a first axle pin. The other end of each push rod is rotatably connected to a connecting block through a second axle pin. The connecting blocks on both sides are fixedly connected to corresponding connecting plates. A drive mechanism for rotating the rotating rod is disposed between the two side plates.

[0011] Preferably, the driving mechanism includes a worm gear and a worm, the worm gear is fixedly sleeved on the wall of the rotating rod, the worm is meshed on the lower side of the worm gear, and both ends of the worm are rotatably connected to the corresponding side plates.

[0012] Preferably, a rotating wheel is fixedly sleeved at one end of the worm gear.

[0013] Preferably, the sidewall of the wheel is provided with anti-slip texture.

[0014] Preferably, both the movable plate and the chute have rectangular cross-sections.

[0015] Preferably, multiple crossbeams are fixedly installed inside the canopy from front to back.

[0016] Preferably, all of the aforementioned inserts are integrally formed with the corresponding connecting plates.

[0017] A method for constructing a large-scale double-span steelmaking plant structure, comprising the large-scale double-span steelmaking plant structure, and the specific steps are as follows:

[0018] Step 1: Install the base. First, place and fix multiple bases according to the mounting holes opened on the lower surface of the ceiling. Then, weld and fix the support rods on the support plates inside the multiple bases.

[0019] Step 2: Install the canopy. Fix and weld multiple crossbeams inside the canopy, and then connect the mounting holes on the lower surface of the canopy to the corresponding support rods to complete the installation of the canopy and the base.

[0020] Step 3: Install the wall panels. Place multiple wall panels together between the base and the ceiling. Then rotate the worm gear, which drives the worm wheel to rotate, causing the rotating rod to rotate. The rotating rod drives the rotating block to rotate, causing the rotating block to rotate the push rods on both sides towards verticality. This causes the two push rods to push the corresponding connecting plates to both sides, so that the connecting plates on both sides abut against the corresponding first and second mounting plates, respectively. This allows multiple insert rods to be inserted into the corresponding holes, thus completing the installation and fixing of the wall panels.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a large-scale double-span steelmaking plant structure and construction method, which has the following beneficial effects:

[0023] This anti-theft factory structure with a buffer mechanism, by rotating the worm gear, drives the worm wheel to rotate, which in turn drives the rotating block to rotate. This causes the rotating block to rotate the push rods on both sides towards the horizontal, thus pulling the connecting plates on both sides towards each other. This allows multiple inserts on both sides to disengage from the corresponding holes on the first and second mounting plates, thereby releasing the restriction on the wall panels. This enables the quick disassembly and replacement of any damaged wall panels without first disassembling other wall panels, greatly improving the efficiency of wall panel replacement.
