[0001] The utility model belongs to the field of building construction, and in particular relates to a dismantling device for a prefabricated support system of a conical silo top plate. Background Art

[0002] In the entire production and operation system of coal and grain storage plants, silos are indispensable as facilities for transfer and storage. Silos are mostly tall cylinders with sloped or funnel-shaped tops, which change the traditional loose stacking method to high-level bundle stacking in a closed space, which not only saves floor space, but also ensures the closed storage environment and reduces the impact on the surrounding environment.

[0003] The pouring construction of the sloped or funnel-shaped top of the silo structure requires the construction of a relatively large steel structure support platform to avoid the super-high construction of the formwork support frame. The construction of the steel structure support platform can use existing slipform equipment, cranes, etc., but when the steel structure support platform is removed after the top plate is poured and hardened, many lifting equipment have been evacuated or it is difficult for large external lifting equipment to transport the steel platform inside the warehouse to the ground outside the warehouse. Even if large lifting equipment is selected, the efficiency of disassembly and transportation is low. Therefore, it is necessary to develop a dismantling device for the prefabricated support system of the conical silo top plate to achieve safe and efficient disassembly of the silo top formwork.

[0032] Each silo top support frame 4 includes an anchor plate 4-1, a vertical pole 4-2, a support beam 4-3, a fixed beam 4-4, and a lifting main beam.

In the figure, two parallel joists 4-3 are used to fix two groups of adjacent vertical poles 4-2. The fixed beam 4-4 is vertically arranged above the supporting beam 4-3 and located at both ends of the supporting beam 4-3, so as to fix and connect the two supporting beams 4-3; an I-shaped lifting main beam 4-5 parallel to the two fixed beams 4-4 is arranged, and the I-shaped lifting main beam 4-5 is erected in the middle position of the two supporting beams 4-3; the cross-sectional shape of the I-shaped lifting main beam 4-5 is I-shaped. An electric hoist 5 is hung below the web and the lower flange of the I-shaped lifting main beam 4-5 to lift materials. The pulley 5-1 of the electric hoist 5 slides along the lower flange of the I-shaped lifting main beam 4-5, and a sling 5-2 is provided at the lower end of the electric hoist 5. The lifting of materials is achieved by lifting or lowering the sling 5-2. The installation diagram of the electric hoist 5 on the I-shaped lifting main beam 4-5 is shown in the figure Figure 3 When necessary, the hopper 5-3 can be matched at the lower end of the sling 5-2 to realize the disassembly and transportation of scattered materials. The multiple slings 5-2 are connected to the steel structure support frame 2 to realize the lifting of the steel structure support frame 2.

[0033] In order to realize the connection of the silo top support frame 4, 25cm×25cm cylinder top plate reserved holes 1-2-1 are reserved at equal intervals on the cylinder top plate 1-2 near the cylinder top bracket 1-3.

In the figure, each silo top support frame 4 includes 4 uprights 4-2 and 4 anchor plates 4-1.

The sling 5-2 of the electric hoist 5 passes through the reserved hole 1-2-1 on the barrel top plate.

[0040] Step 2: Remove the round steel pipe 3-1 and the template 3-2 of the template support frame 3, and place the components on the hopper 5-3 nearby, such as Figure 5 As shown, the electric hoist 5 is slid from the I-shaped lifting main beam 4-5 to the gap between the roof trusses 2-2, and the sling 5-2 is lowered to transport the disassembled formwork support frame 3 components to the ground.

[0041] Step 3: Remove the hopper 5-3 hanging on the sling 5-2, tie the slings 5-2 at each position to the roof truss 2-2, and use the wire rope 2-1 to tie and secure some of the rods of the steel structure support frame 2. Figure 6 After the slings 5 ​​- 2 of the electric hoists 5 at each position are hung, the connection between the roof truss 2 - 2 and the embedded support 1 - 4 is removed.

[0042] Step 4: Synchronously lower the slings 5 ​​- 2 of the electric hoists 5 at each position, and check whether the electric hoists 5 at each position are lowered synchronously through the strain gauges on the longitudinal reinforcement trusses 2 - 3 .

[0043] Step 5: After the steel structure support frame is lowered to the ground, Figure 7 As shown, its components are disassembled on the ground and transported to the next project.
