Description

Technical Field

[0001] The utility model relates to the field of building formwork support, in particular to a steel pipe column structure for the roof of a high elevated area. Background Technique

[0002] In a large number of engineering constructions, large-span and ultra-high elevated area roof concrete structures are often encountered, such as in the local process production area of a large factory building, the atrium of a large shopping mall, etc. To meet the production process requirements or to meet lighting, ventilation, personnel flow, etc., some large-span and ultra-high elevated areas may be designed. The roof concrete structure in this area has the characteristics of large span, high structure, large beam cross-section, etc., bringing many difficulties and challenges to the construction of the roof structure. The existing bottom support systems for large-span and ultra-high elevated area structures are mainly divided into two types: full hall steel pipe support systems and Bailey frame support platforms. However, when facing building structures with large spans and high heights, these traditional support systems often seem inadequate. They not only do not have obvious advantages in economic benefits, but their bearing capacity and stability also face severe challenges, thus bringing greater construction risks. More importantly, as the height of the support system increases, the economy of these traditional solutions will be further reduced, seriously affecting the cost-effectiveness of the overall project. Content of the Utility Model

[0003] Based on this, the purpose of the utility model is to provide a steel pipe column structure for the roof of a high elevated area to solve the technical problem that the traditional support system does not have obvious economic benefits for building structures with large spans and high heights.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A steel pipe column structure for the roof of a high elevated area, including a circular pipe column and three layers of structural plates. A structural steel main beam is arranged at the top end of the circular pipe column. A plurality of structural steel secondary main beams are arranged on both sides of the top of the structural steel main beam. A steel structure support is arranged at the top of the structural steel secondary main beam. A formwork support is arranged at the top of the steel structure support. A roof concrete beam and slab is arranged at the top of the formwork support.

[0005] By adopting the above technical scheme, the bearing capacity of the steel structure platform placed on the cast-in-place floor slab can be fully utilized. In order to prevent the middle area of the steel platform from having too large a deflection due to overload, a support circular pipe column is designed to be added in the middle area. This measure not only saves the cost investment in foundation reinforcement or floor backlining, but also effectively solves the structural safety problems that may be caused by the formwork support of the beam and slab.

[0006] Further, a plurality of the structural steel secondary main beams are arranged at equal intervals linearly along the length line of the structural steel main beam.

[0007] By adopting the above technical solutions, the load distribution of the entire steel platform can be ensured to be uniform. This layout optimizes the stress performance of the structure, prevents structural deformation or damage caused by local overload, and thus improves the stability and safety of the entire steel platform.

[0008] Furthermore, the structural steel main beam is of the HM440×300×11×18 steel structure type, and the circular tube column is fixedly welded to the structural steel main beam.

[0009] By adopting the above technical solutions, the structural steel main beam is of the HM44,0×300×11×18 steel structure type. This type has high load-bearing capacity and stability, can withstand various loads from the steel platform and its upper part, and ensures the stability of the entire structure.

[0010] Furthermore, multiple circular tube columns are provided, and the multiple circular tube columns are arranged in an equidistant linear pattern. The circular tube column is of the Φ500×12 type.

[0011] By adopting the above technical solutions, multiple circular tube columns are provided, and these circular tube columns are arranged in an equidistant linear pattern, which can ensure the uniform support and stability of the entire structure. This layout effectively disperses the load, prevents the situation of single-point overload, and thus improves the load-bearing capacity and safety of the entire steel platform.

[0012] Furthermore, the structural steel secondary main beam is of the HM440×300×11×18 steel main beam type.

[0013] By adopting the above technical solutions, the structural steel secondary main beam is of the HM440×300×11×18 steel main beam type, which has high bearing capacity and stability. The steel beam of this type can effectively support the floor and transfer the load, ensuring the structural safety of the steel platform under various usage conditions.

[0014] Furthermore, the steel structure support is composed of multiple H-shaped steels HW100×100×6×8, and is fixedly welded to the structural steel secondary main beam.

[0015] By adopting the above technical solutions, multiple H-shaped steels HW100×100×6×8 have high strength and stability, can withstand large loads, and ensure the stability of the steel platform. The combined use of multiple H-shaped steels further enhances the load-bearing capacity of the support, enabling it to better support the steel platform and the loads thereon.

[0016] Furthermore, steel pipes and steel bars are fixedly welded on the steel structure support, and a 1-mm-thick floor formwork is fully laid for hard enclosure to prevent sundries from falling.

[0017] By adopting the above technical solution, the steel pipes and steel bars welded and fixed on the steel structure support enhance the overall stability of the structure. These reinforcement measures make the support more solid and able to withstand greater external forces and loads, thereby improving the safety of the entire platform.

[0018] Furthermore, a scaffold is provided on the outside of the circular tube column, and inclined rods are installed on both sides of the scaffold.

[0019] By adopting the above technical solution, the scaffolding on the outside of the circular tube column provides a stable working platform for construction, which is convenient for workers to carry out various operations such as installation and maintenance, ensuring the smooth progress of construction operations, not only improving work efficiency, but also ensuring the safety of the construction process.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model uses the structural construction operation of round tube columns, structural steel main beams and structural steel secondary main beams, the roof steel tube columns of the super-high overhead area between the large spans of the factory building and the steel structure formwork platform to fully utilize the bearing capacity of the steel structure platform structure itself placed on the cast-in-place structure floor. At the same time, in order to prevent the middle part of the steel platform from being overloaded and causing excessive deflection, supporting round tube columns are added in the middle area, which saves the investment in foundation reinforcement or floor top return, and well solves the difficult problem that the beam and slab support top is prone to structural safety accidents. The steel structure truss beams and I-beam platforms are clearly stressed, safe and reliable, and the process is simple. The steel sections of the steel structure trusses, frame beams and I-beam platforms have a high recycling rate and are economical and reasonable. The ground-type elevated formwork is converted into an ordinary formwork through the steel platform, which avoids the large investment in steel pipe scaffolding, reduces labor intensity, occupies a small area, and is convenient for three-dimensional cross-operation.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] A steel pipe column structure for an elevated roof, such as Figures 1 - 4 As shown, it includes a circular tube column 1 and a three-layer structural plate 8. The top of the circular tube column 1 is provided with a structural steel main beam 2. Both sides of the top of the structural steel main beam 2 are provided with multiple structural steel secondary main beams 3. The top of the structural steel secondary main beam 3 is provided with a steel structure bracket 4. The top of the steel structure bracket 4 is provided with a formwork frame 6. The top of the formwork frame 6 is provided with a roof concrete beam plate 7. It can fully utilize the bearing capacity of the steel structure platform placed on the cast-in-place floor slab. In order to prevent the middle of the steel platform from causing excessive deflection due to overload, a supporting circular support is added in the middle area. Pipe column 1, this measure not only saves the cost of foundation reinforcement or floor top-up, but also effectively solves the structural safety problems that may be caused by beam and slab support. At the same time, the design of steel structure truss beams and I-beam platforms has clear force, which is both safe and reliable and simple to use. These steel structure materials have a high recycling rate and are economical and reasonable. Through the steel platform, the complex ground-type elevated formwork is cleverly simplified to ordinary formwork, thereby avoiding the large investment in steel pipe scaffolding, reducing labor intensity, saving space, and making it easier to carry out three-dimensional cross-operation.

[0032] SeeFigure 1 , Figure 4 , multiple secondary main structural steel beams 3 are arranged linearly at equal intervals along the length line of the main structural steel beam 2, which can ensure uniform load distribution across the entire steel platform. This layout optimizes the stress performance of the structure, preventing structural deformation or damage caused by local overload, thereby enhancing the stability and safety of the entire steel platform. Meanwhile, the equally spaced linearly arranged secondary main structural steel beams 3 also simplify the construction process and material management. Since all secondary main beams are arranged at equal intervals, this makes the installation process more standardized and efficient, reducing the complexity and error rate during construction. This setup also facilitates subsequent maintenance and repair work because all structural components follow a unified layout rule.

[0033] Refer to Figure 4 , the model of the main structural steel beam 2 is HM440×300×11×18 steel structure. The circular tube column 1 is welded and fixed to the main structural steel beam 2. The main structural steel beam 2 adopts the HM440×300×11×18 model of steel structure, which has high load-bearing capacity and stability, can withstand various loads from the steel platform and above it, ensuring the stability of the entire structure. Meanwhile, its specification size is moderate, meeting both the mechanical property requirements and avoiding unnecessary material waste. At the same time, the circular tube column and the main structural steel beam are fixed by welding. This connection method ensures a tight combination between the two, enhancing the rigidity of the overall structure. Welding fixation is not only simple and feasible but also has high connection strength, capable of effectively transmitting and dispersing loads, further enhancing the overall stability and safety of the steel platform.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , multiple circular tube columns 1 are provided, and the multiple circular tube columns 1 are arranged linearly at equal intervals. The model of the circular tube column 1 is Φ500×12. Providing multiple circular tube columns 1 and arranging these circular tube columns 1 linearly at equal intervals can ensure uniform support and stability of the entire structure. This layout effectively disperses the load, preventing single-point overload, thereby enhancing the load-bearing capacity and safety of the entire steel platform. Meanwhile, using the circular tube column 1 with the model Φ500×12, this specification of column has high strength and stiffness, capable of withstanding large pressure and bending moment, further ensuring the stability of the structure. The equally spaced linearly arranged circular tube columns 1 also facilitate construction and installation, improving work efficiency and providing convenience for subsequent maintenance and repair work.

[0035] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, the structural steel secondary main beam 3 is of the HM440×300×11×18 steel main beam type. The structural steel secondary main beam uses a steel main beam of the HM440×300×11×18 type, which has high bearing capacity and stability. This type of steel beam can effectively support the floor and transfer loads, ensuring the structural safety of the steel platform under various usage conditions. At the same time, the steel main beam of the HM440×300×11×18 type has a high degree of standardization, which is convenient for procurement and replacement, reducing the costs of maintenance and repair. Its structural design is reasonable, optimizing the use efficiency of steel. It not only meets the structural strength requirements but also avoids material waste, thus achieving the dual goals of economy and safety.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 4 , the steel structure support 4 is composed of multiple H-shaped steels HW100×100×6×8 and is welded and fixed to the structural steel secondary main beam 3. The multiple H-shaped steels HW100×100×6×8 have high strength and stability, can bear large loads, and ensure the stability of the steel platform. The combined use of multiple H-shaped steels further enhances the bearing capacity of the support, enabling it to better support the steel platform and the loads thereon. At the same time, the steel structure support 4 and the structural steel secondary main beam 3 are fixed by welding. This connection method ensures the close combination between the support and the secondary main beam, improving the overall structural stability. Welding fixation not only has high connection strength but also can effectively transfer loads, preventing structural loosening or deformation, thus ensuring the safety and reliability of the steel platform.

[0037] Refer to Figure 1 、 Figure 2 , steel pipes and steel bars are welded and fixed on the steel structure support 4, and a 1-mm-thick floor formwork is fully paved for hard enclosure to prevent sundries from falling. The steel pipes and steel bars welded and fixed on the steel structure support 4 enhance the overall stability of the structure. These reinforcement measures make the support more firm and able to bear greater external forces and loads, thus improving the safety of the entire platform. At the same time, fully paving a 1-mm-thick floor formwork for hard enclosure effectively prevents sundries from falling from the platform. This enclosure measure not only protects the safety of the area below, avoiding accidental injuries caused by falling objects, but also makes the platform cleaner and more convenient for cleaning and maintenance. In addition, the laying of the floor formwork also increases the bearing capacity of the platform, enabling it to better disperse and transfer loads, further enhancing the stability and safety of the structure.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3, a scaffold is provided on the outer side of the circular pipe column 1, and diagonal braces 5 are installed on both sides of the scaffold. The scaffold on the outer side of the circular pipe column provides a stable working platform for construction, facilitating workers to carry out various operations such as installation and maintenance, ensuring the smooth progress of construction operations, not only improving work efficiency but also ensuring the safety of the construction process. At the same time, the diagonal braces 5 installed on both sides of the scaffold significantly enhance the structural stability. The diagonal braces 5 can resist the deformation of the scaffold caused by wind force and other external forces, effectively preventing the scaffold from tilting or collapsing, further protecting the safety of construction workers. The addition of the diagonal braces 5 also optimizes the force distribution of the scaffold, making it more uniform and reasonable, and extending the service life of the scaffold.
