Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically an adaptive spiral locking component and its usage method. Background Technology

[0002] In recent years, with economic development and the need to accommodate various sports and performance functions, stadiums have been constructed on a large scale, and the use of heavy-duty movable structures has become a new trend. To achieve the lifting and lowering of movable structures, a beam-column joint design is required that facilitates rapid on-site construction while ensuring load-bearing capacity. Currently, most beam-column joints in heavy-duty movable structures use fully bolted connections, which are costly, labor-intensive, and technically demanding during mode replacement. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects and propose an adaptive spiral locking device that is suitable for movable structures, especially heavy structures. In one state, the platform can withstand a large load and achieve a rigid connection between beam and column nodes. In another state, the platform can move up and down along the frame columns as a whole. Furthermore, it can be repeatedly installed and disassembled, and the conversion process is simple to operate.

[0004] To achieve the above objectives, the present invention is implemented as follows: An adaptive spiral locking assembly includes a ring beam, a central upper movable pin, a central lower movable pin, and a rotating core seat; in, The ring beam is used for connecting the frame beams; in the locked state, it adjusts the internal forces of the frame beams on both sides of the node; in the disengaged state, the ring beam and the frame beam form a stable structural system with high rigidity, making it easy to move the platform up and down as a whole; a fixed pin is set on the inner side of the ring beam for mechanical engagement with the central movable pin; The central upper movable pin and the central lower movable pin are rotatable parts. By rotating the central movable pin, the adaptive screw locking assembly can be locked or disengaged. Rotary core seat is used for frame column connection joints and central movable pin support structure; in, The bottom of the lower tooth groove of the central movable pin is inclined, and the corresponding position of the tooth of the fixed pin on the inner side of the ring beam is also inclined at the same angle. The contact surfaces between the central lower movable pin and the rotating core seat, the central lower movable pin and the fixed pin, and the central upper movable pin and the fixed pin are machined, chrome-plated, and grease-lubricated; the contact surfaces between the central upper movable pin and the rotating core seat are threaded, blackened, and sealed with grease. The fixed pin, the central upper movable pin, and the central lower movable pin are made of forgings or castings.

[0005] The method of using the adaptive spiral locking component includes: Step 1, Locked State: Step 1.1: Rotate the central lower movable pin until its teeth are tightly engaged with the teeth of the fixed pin; Step 1.2: Install the central movable pin until its teeth are tightly engaged with the teeth of the fixed pin; Step 2, Disconnected state: Step 2.1: Remove the central movable pin; Step 2.2: Install the T-shaped column on the top of the rotating core seat; Step 2.3: Install the hydraulic lifting equipment; Step 2.4: Tension the rope between the T-shaped column and the ring beam; Step 2.5: Rotate the central lower movable pin 45°; Step 2.6: Lowering the platform, frame beams, and floor slabs; Step 2.7: Remove the central lower movable pin and the rotating core seat.

[0006] Currently, most beam-column joints in heavy-duty mobile structures are connected entirely with bolts. Each mode change requires the installation and removal of bolts within a few days, resulting in a large workload and significant manpower. To ensure the structure's reusability, fabrication and installation require higher precision, and bolt installation demands a higher perforation rate, requiring highly skilled personnel. Furthermore, the bolts cannot be reused; each installation / removal necessitates replacement with new bolts, incurring substantial costs.

[0007] Taking into account the above factors, the present invention allows the device to bear a large load in the locked state and effectively restrict the displacement and rotation of the frame beam, achieving a rigid connection between the beam and column nodes; in the disengaged state, the platform (frame beam and floor slab) can move up and down along the frame column as a whole; the various parts are mechanically meshed and can be repeatedly installed and disassembled; the conversion process is simple to operate, and the central movable pin can be rotated by applying a small torque (manual rotation).

[0023] The present invention will be further illustrated below through specific embodiments.

[0024] An adaptive spiral locking component suitable for beam-column joints in active structures (frame structures). Figure 1 This is especially true for heavy-duty mobile structures. The platform can withstand large loads (such as a platform fully covered with personnel loads) and achieves rigid connections between beam and column joints, i.e., a locked state. Figure 2 and Figure 3 The platform (frame beams and floor slabs) can move up and down along the frame columns as a whole, which is the detached state. Figure 4 and Figure 5 ).

[0025] The adaptive spiral locking assembly comprises four parts: a ring beam, a central upper movable pin, a central lower movable pin, and a rotating core seat; wherein... Ring beam ( Figure 6 The frame beam connection joint can effectively adjust the internal forces of the frame beams on both sides of the node in the locked state; in the disengaged state, the ring beam and the frame beam can form a stable structural system with greater rigidity, making it easy to move the platform up and down as a whole; a fixed pin is set on the inner side of the ring beam for mechanical engagement with the central movable pin.

[0026] Central activity sales ( Figure 7 The rotatable part can achieve two states (locked and unlocked) by rotating.

[0027] Rotating core holder ( Figure 8 ), frame column connection joint; central movable pin support structure.

[0028] Specific device structure: The bottom of the lower tooth groove of the central movable pin is inclined. Figure 15 The corresponding position of the fixed pin teeth is also tilted at the same angle to facilitate rotational engagement.

[0029] The contact surfaces between the central lower movable pin and the rotating core seat, the central lower movable pin and the fixed pin, and the central upper movable pin and the fixed pin are machined / chrome-plated / greased. Figure 14 This facilitates rotation; the contact surfaces between the central movable pin and the rotating core seat are sealed using open threading / blackening / grease filling. Figure 14 This makes it easy to install and disassemble.

[0030] The fixed pin and the central movable pin are made of forgings / castings to facilitate machining.

[0031] The four parts of the device are mechanically connected, allowing for repeated installation and disassembly; the pin tooth contact rotating surface is specially treated. Figure 13 This can effectively reduce the coefficient of friction; using a rotating handle ( Figure 11 The central movable pin can be rotated by applying only a small torque (manual rotation).

[0032] Locking state implementation method: Rotate the central lower movable pin ( Figure 11 ), until its teeth meet the teeth of the fixing pin ( Figure 12 Tightly engaged; installation of the central movable pin ( Figure 11 ), until its teeth meet the teeth of the fixing pin ( Figure 12 They mesh tightly.

[0033] Force transmission path in locked state: frame beam → ring beam ( Figure 6 → Central activity sales ( Figure 7 → Rotating Core ( Figure 8 → Frame columns allow for effective transmission of internal forces. The frame columns, through a rotating core seat → central movable pin → ring beam, effectively constrain the displacement and rotation of the frame beams, achieving a rigid connection between the beam and column joints. Figure 9 ).

[0034] Methods for implementing detached states ( Figure 10): Remove the central upper movable pin → Install the T-shaped column (at the top of the rotating core seat) → Install the hydraulic lifting equipment → Tension the rope between the T-shaped column and the ring beam → Rotate the central lower movable pin 45° → Lower the platform (frame beam and floor slab) → Remove the central lower movable pin and the rotating core seat.

[0035] Method for rotating the central movable pin: Remove the upper central movable pin, and then rotate the lower central movable pin (45°) until its teeth are completely disengaged from the teeth of the fixed pin.
