An adjustable steel internal support platform device for silo slipform construction Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to an adjustable steel internal support platform device for silo slipform construction, which is suitable for the construction and adjustment of the internal support platform in silo slipform construction with a diameter of up to 26 meters. Background Technology

[0002] Existing slipform construction methods for silos mostly employ flexible internal platforms, which have the following technical drawbacks:

[0003] 1. Insufficient platform space: The flexible platform has only a 1.5m wide operating surface along the cylinder wall, and the material loading area intersects with the construction passage, resulting in uneven load distribution and poor slip-lift stability.

[0004] 2. High safety risks: The installation of steel beams on the warehouse roof relies on suspended cage operations, which poses a high risk to workers operating at heights; the sealing of beam sockets requires repeated formwork erection, which is inefficient and prone to quality defects.

[0005] 3. Low construction efficiency: In traditional processes, the slipform platform and the silo top construction cannot be coordinated, and the connection between processes is interrupted, resulting in a delay in the construction period.

[0006] 4. Lack of adjustment function: The existing platform is a flexible structure that cannot adapt to the needs of different elevation operations, resulting in repeated assembly and disassembly and serious waste of materials.

[0007] Therefore, we propose an adjustable steel internal support platform device for silo slipform construction. Summary of the Invention

[0012] The central steel cylinder has a diameter of 700mm and a height of 1500mm. It is fixedly connected to the I-beam main beam by a flange and M24 bolts. There are 16 sets of bolt holes evenly distributed on the flange to enhance stability.

[0013] Round steel tie rod: Φ25 round steel, both ends are connected to the I-beam main beam and the central steel cylinder by turnbuckles. Adjust the tension so that the central steel cylinder is suspended by 1cm to ensure uniform force distribution.

[0014] Bracket embedded part: L-shaped 16# steel plate, embedded 1.5m below the bottom elevation of the steel beam on the top of the silo, welded and fixed to the embedded steel plate on the cylinder wall, and equipped with an electric hoist to realize the platform lifting.

[0015] Platform laying layer: The closed rigid operating platform is composed of ring steel pipes, timber and film-coated multi-layer boards; the timber is spaced 200mm apart and is fixed to the steel pipes by iron wire.

[0016] This utility model has the following beneficial effects:

[0017] 1. Significantly expanded operating area: The platform area has increased from the traditional 120㎡ to 953㎡, with clear division of material storage area, equipment passage and work surface, reducing cross-process interference.

[0018] 2. Enhanced safety performance: The platform elevation can be adjusted by electric hoists, avoiding high-altitude cage operations and reducing the accident rate by 80%.

[0029] Please refer to Figures 1-4. This utility model is an adjustable steel internal support platform device for silo slipform construction, comprising the following components:

[0030] I-beam main beam 1: 16 I-beams (model HN250×125×6×9mm) are evenly distributed radially along the silo. The top is covered with ring steel pipe 7 and timber 8 to form the foundation load-bearing structure.

[0031] The central steel cylinder 2 has a diameter of 700mm and a height of 1500mm. It is fixedly connected to the I-beam main beam 1 by flange 6 and M24 bolts. There are 16 sets of bolt holes evenly distributed on the flange to enhance stability.

[0032] Round steel tie rod 3: Φ25 round steel, both ends are connected to the I-beam main beam 1 and the central steel cylinder 2 by turnbuckles. Adjust the tension so that the central steel cylinder is suspended by 1cm to ensure uniform force distribution.

[0033] Bracket embedded part 4: L-shaped 16# steel plate, embedded 1.5m below the bottom elevation of the steel beam on the top of the silo, and welded and fixed to the embedded steel plate 11 on the cylinder wall, and equipped with electric hoist 10 to realize platform lifting.

[0034] Platform laying layer 5: It consists of a closed rigid operating platform composed of ring steel pipe 7, timber 8 and film-coated multilayer board 9; the timber 8 are spaced 200mm apart and are fixed to the steel pipe by iron wire.

[0035] Please refer to Figures 1-4. This embodiment illustrates the installation method of the components of an adjustable steel internal support platform device for silo slipform construction:

[0036] 1. Installation of I-beam main beam 1: 16 I-beam main beams 1 are evenly distributed along the radial direction of the silo. They are aligned with the central steel cylinder 2 through flange 6 and fixed with M24 bolts to ensure that the connection between each component is reliable and the position is accurate.

[0037] 2. Fixing the central steel cylinder 2: Use lifting equipment to hoist the central steel cylinder 2 to the preset position. After aligning the flange 6 with the bolt holes of the I-beam 1, reinforce it with M24 bolts to ensure that the overall structure remains stable under stress. After installation, check all connections to ensure that there is no looseness or deviation.

[0038] 3. Adjustment of round steel tie rods 3: Install Φ25 round steel tie rods between the I-beam main beam 1 and the central steel cylinder 2. The round steel tie rods 3 are connected by turnbuckles to adjust the tension. During installation, each round steel tie rod 3 should be adjusted so that the central steel cylinder 2 is suspended by about 1cm to ensure that the platform is evenly stressed. During the tension adjustment process, the construction personnel should use special tools such as torque wrenches to check all connection parts to ensure that the tension of the tie rods meets the design requirements, thereby realizing the overall rigidity and adjustment function of the internal support platform.

[0039] 4. Installation of the bracket embedded part 4 and the electric hoist 10: The bracket embedded part 4 is made of L-shaped 16# steel plate and embedded at an elevation of 1.5m below the steel beam on the top of the silo. It is then fixed to the cylinder wall by welding with the embedded 16# steel plate 11. After the embedding is completed, the electric hoist 10 is installed on the climbing rod. This lifting device enables the platform height adjustment function. During the installation process, it is essential to ensure that the embedded part and the electric hoist 10 are firmly installed to prevent displacement under platform lifting or external loads. At the same time, the welding quality and fixing status are strictly inspected to ensure safe use.

[0040] 5. Construction of Platform Laying Layer 5: First, lay the ring-shaped steel pipe 7 on top of the I-beam main beam 1 to form the basic framework of the platform. Second, lay timber 8 on the steel pipe framework according to the design requirements, maintaining a 200mm spacing between each timber 8, and use wire to bind and fix it to the steel pipe to ensure sufficient rigidity of the overall structure. Finally, lay film-coated plywood 9 on the surface of the timber 8 to form a closed, rigid operating platform. During the laying process, attention should be paid to the connection between each board surface and the edge fixing to ensure that the platform is flat and stable, facilitating safe operation for construction personnel.
