Description

Technical Field

[0001] This utility model relates to a large-scale granulation tower steel grid construction platform, belonging to the field of granulation tower construction technology. Background Technology

[0002] The construction of a granulation tower requires the use of an aerial work platform for the construction of the upper steel-concrete structure. However, the large diameter of the granulation tower's inner cylinder necessitates the use of a traditional H-beam aerial work platform. This would involve excessive steel consumption, high risks during construction and dismantling, and significant time commitment. Furthermore, it would require a large truck crane for lifting, which is inefficient due to limited space constraints and high costs. Therefore, a traditional H-beam construction platform cannot meet the construction requirements. To address these issues, a new technical solution is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a large-scale granulation tower steel grid construction platform to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a large granulation tower steel grid construction platform, including a granulation tower, on which steel brackets and bolted spherical steel grids are provided. The steel brackets are pre-embedded in 12 equal parts above the inner wall of the granulation tower. The steel brackets are welded together from a pre-embedded steel plate, a support plate, an inclined bottom plate, and a reinforcing plate. The pre-embedded steel plate has 16 bolt holes equidistantly opened. The support plate has connection holes distributed in a quadrilateral pattern. The bolted spherical steel grid is placed inside the granulation tower and is fixedly connected to the support plate by bolts.

[0005] Preferably, the bolted spherical steel grid frame has bolted balls distributed in a ring at equal intervals above and below, and the top of the upper bolted ball is connected to a steel base by a thread.

[0006] Preferably, the horizontally adjacent bolt balls are connected by a main support rod via threads, and the vertically staggered bolt balls are connected by a secondary support rod via threads.

[0007] Preferably, the bolt hole is welded to the main reinforcement of the inner wall of the granulation tower by means of anchor bars.

[0008] Preferably, a screw is provided on the steel base, a support column is integrally formed and connected to the top of the screw, and a support disc is integrally formed and connected to the top of the support column.

[0009] Compared with the existing technology, the beneficial effects of this utility model are as follows: Compared with the traditional H-beam steel construction platform, this utility model has good stress performance, can withstand various loads, has good overall stability, improves the safety operation factor, greatly reduces the amount of steel used, and the innovative method of pre-customized processing and manufacturing by the manufacturer, on-site assembly, and overall lifting and installation accelerates the construction platform construction speed and greatly saves the construction period.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figure 1-4 As shown, a large granulation tower steel grid construction platform includes a granulation tower 1. Steel brackets 2 and bolted spherical steel grids 3 are installed on the granulation tower 1. The steel brackets 2 are pre-embedded in 12 equal sections above the inner wall of the granulation tower 1. The steel brackets 2 are welded from pre-embedded steel plates 4, support plates 5, inclined bottom plates 6, and reinforcing plates 7. Sixteen bolt holes 8 are evenly spaced on the pre-embedded steel plates 4. Connection holes 9 are distributed in a quadrilateral pattern on the support plates 5. The bolted spherical steel grids 3 are placed inside the granulation tower 1 and fixed to the support plates 5 with bolts. The bolted spherical steel grid frame 3 is connected with bolted balls 10 distributed in a ring at equal intervals on the upper and lower sides. The top of the upper bolted balls 10 is connected to a steel base 11 by threads. The horizontally adjacent bolted balls 10 are connected to a main support rod 12 by threads. The staggered bolted balls 10 are connected to a secondary support rod 13 by threads. The bolt holes 8 are welded to the main reinforcement of the inner wall of the granulation tower 1 by anchor bars. The steel base 11 is provided with a screw rod 14. The top of the screw rod 14 is integrally connected to a support column 15. The top of the support column 15 is integrally connected to a support disc 16.

[0017] Specific usage: Using construction engineering surveying tools, quickly and accurately install and fix six "5t winches + 10t pulleys" integrated lifting devices to the top of granulation tower 1. Then, assemble the bolted spherical steel grid 3 on the floor of granulation tower 1, leaving the outermost grid nodes and chords uninstalled. Simultaneously, set six equally spaced lifting points on the bolted spherical steel grid 3. Then, use the six "5t winches + 10t pulleys" integrated lifting devices to simultaneously lift the bolted spherical steel grid 3 from the six equally spaced lifting points. During the overall lifting process, observe and control the balance of the bolted spherical steel grid 3. Measure the level of the bolted spherical steel grid 3 with a steel ruler every 1.5 meters of lifting height. Adjust the winches individually to control the bolted spherical steel grid 3. The horizontal height difference of the bolted spherical steel grid frame 3 is kept within 30 cm. After the six winches lift the bolted spherical steel grid frame 3 to the top of the granulation tower 1, the outermost grid frame is assembled and lowered onto the 12 pre-fabricated steel brackets 2, completing the positioning and installation of the steel brackets 2 and the bolted spherical steel grid frame 3. Finally, the steel base 11 is used as the main load-bearing node of the GHJ steel truss. With the help of the bolted spherical steel grid frame 3 construction platform, the hoisting of the GHJ rigid steel truss of the upper structure of the granulation tower 1 and the construction of the steel-concrete structure are completed. After the upper structure construction is completed, the bolted spherical steel grid frame 3 platform is lowered onto the scraping layer of the granulation tower for dismantling and disassembly, and then lifted out through the hoisting hole.
