Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of support systems, in particular to a structural column support type heavy-load conversion system. Background Art
[0002] With my country's remarkable economic growth, a large number of steel-structured exhibition halls, airports, industrial plants, and high-rise buildings have sprung up. Steel structure installation often relies on large-scale machinery for hoisting and construction. Many projects include basement structures, requiring large machinery to hoist the steel structure onto the basement roof and load large amounts of material onto the roof. Avoiding significant damage to the roof and impacting the construction of the underground structure presents a challenge.
[0003] The traditional reinforcement method is to erect scaffolding at the bottom of the basement roof. This reinforcement method has the following disadvantages: (1) Scaffolding supports are mostly point supports, which can easily cause floor cracks. (2) It affects the installation of secondary structures, mechanical and electrical engineering, etc. in the basement. (3) Scaffolding rental fees are high, and the labor costs for installation and removal are high. Summary of the Invention
[0004] In view of the above-mentioned prior art, the present invention proposes a structural column supported heavy-load transfer system.
[0005] The utility model provides a structural column supported heavy-load transfer system, which includes a basement floor, a plurality of structural columns are provided at the upper end of the basement floor, a basement roof is provided at the upper end of the plurality of structural columns, a steel platform is provided at the upper end of the basement roof, the steel platform includes two relatively arranged main steel beams, a plurality of secondary steel beams are provided between the two main steel beams, and a roadbed box is provided at the upper end of the steel platform.
[0006] Preferably, a plurality of engineering piles are provided at the lower end of the basement floor.
[0007] Preferably, a buttress plate is provided at the lower end of the main steel beam and directly above the structural column.
[0008] Preferably, the main steel beam and the secondary steel beam are both made of Q355B material, and the main steel beam and the secondary steel beam are connected by welding, and the yield strength is not less than 690MPa.
[0009] Preferably, the roadbed box is fully laid on the steel platform.
[0010] Preferably, the thickness of the buttress plate is 3 cm.
[0011] Compared with the existing technology, the beneficial effects of the present invention are as follows: the present invention proposes a structural column supported heavy load conversion system, and a force conversion structural pier plate is arranged at the bottom of the steel platform to directly transfer the upper load to the structural column, avoiding the heavy load acting on the floor slab and reducing the risk of damage; the steel section assembly and welding method is adopted, the force transmission path is clear, and it can be used multiple times, which increases the economy of the platform; since there is no need to lay a full-floor scaffolding for top plate reinforcement support, the construction process will not affect the secondary structure of the basement and mechanical and electrical installation and other projects, shortening the construction period and reducing the overall cost.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.
[0016] Example: Figure 1-Figure 2 As shown, a structural column-supported heavy-load transfer system includes a basement floor 9, the lower end of which is provided with several engineering piles 8, which are set in the underlying soil 10. Four structural columns 7 are provided at the upper end of the basement floor 9, evenly distributed at the four corners of the basement floor 9. The upper ends of the four structural columns 7 are provided with a basement roof 6, and the upper end of the basement roof 6 is provided with a steel platform. The steel platform includes two main steel beams 3 arranged opposite each other, and a 3 cm thick buttress plate 5 is provided at the lower end of the main steel beams 3 and directly above the structural columns 7 to transfer the upper load to the structural columns 7. Several secondary steel beams 4 are provided between the two main steel beams 3, and the top ends of the main steel beams 3 and the secondary steel beams 4 are located at the same elevation. A roadbed box 2 is provided at the upper end of the steel platform, and the roadbed box 2 is fully spread on the steel platform to ensure the safety of large machinery traveling on the steel platform. The top of the roadbed box 2 is used to set the mechanical load 1. The main steel beam 3 and the secondary steel beam 4 are both made of Q355B material. The main steel beam 3 and the secondary steel beam 4 are connected by welding, and the yield strength is 690 MPa.
[0017] During construction, the heavy-load transfer system involves installing a steel platform on the basement ceiling 6, located along the fixed travel path of large machinery. The upper portion of the platform consists of a fully paved roadbed box 2, with buttress plates 5 positioned below, supported by structural columns 7. The columns 7 bear the entire load, leaving the concrete floor slab and beams of the basement ceiling 6 empty. The deadweight of the large machinery and the load of hoisted components are transmitted from the roadbed box 2 to the secondary steel beams 4, primary steel beams 3, buttress plates 5, structural columns 7, and finally engineering piles 8. This entire force transmission system meets design requirements, offers strong construction feasibility, and protects concrete beams and slabs from stress, ensuring the safety and stability of the concrete structure.
[0018] The above is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent scheme made using the contents of the present invention specification, directly or indirectly used in other related technical fields, is also within the patent protection scope of the present invention.
