Description
Technical Field
[0001] The present invention relates to the field of engineering technology, in particular to the field of steel structure support, and specifically to a high-altitude cantilever steel structure support component and a use method thereof. Background Art
[0002] Cantilever structure is a term used in the engineering industry. It mainly refers to an effect achieved by building components using other structural designs. Part or all of the building is unsupported below, giving people a visual effect of being suspended in the air, and is mainly subjected to lateral forces. Cantilever structure is one of the common structural forms in engineering structures, such as awnings, eaves, external balconies, and cantilevered corridors in construction projects. This structure is a cantilever structure formed by cantilevering beams or plates from the main structure. It is essentially a beam-slab structure.
[0003] With the acceleration of urbanization and the development of high-rise buildings, high-altitude cantilever steel structure support components are increasingly used in modern buildings. High-altitude cantilever structures are usually used in balconies, viewing platforms, eaves, billboard brackets and other parts of buildings. These structures not only require high strength and high stability, but also need to maintain good performance under complex load conditions.
[0004] Existing steel structure support components have the following major problems and challenges in practical applications: Under high load conditions, cantilever beams are prone to excessive deflection and deformation, and even the risk of structural damage, which not only affects the functional use of the structure, but also may bring safety hazards; high-altitude operations have high technical requirements for construction personnel, which increases the difficulty of construction and safety risks. How to simplify the construction process, improve installation efficiency, and reduce construction costs is still a problem that needs to be solved. Summary of the invention
[0005] The present invention provides a high-altitude cantilever steel structure support component and a use method thereof to solve a series of problems such as the existing cantilever beam is prone to structural damage under high load and high altitude operation is difficult.
[0006] The present invention is implemented by the following technical solutions: A high-altitude cantilever steel structure support assembly includes a support structure installed on a wall, the support structure includes a main beam, a pair of parallel upper support beams are installed on the side of the web of the main beam close to the wall, and the free ends of the upper support beams are fixed to the wall; a pair of parallel lower support beams are installed on the bottom surface of the main beam, a lower reinforcement rod is fixedly installed between the two lower support beams, a horizontal lower cantilever beam is installed on the bottom surface of the main beam between the two lower support beams, and an oblique support rod connected to the lower reinforcement rod is installed at the lower part of the free end of the lower cantilever beam; the upper surface of the lower cantilever beam is supported by an upper cantilever beam through a plurality of web rods, one end of the upper cantilever beam is fixed to the upper surface of the main beam, an operating table is installed on the main beam, and two adjacent operating tables are connected by a connecting plate and fastening bolts.
[0007] During implementation, it includes a supporting structure installed on the wall. The connection nodes of the supporting structure are all connected by high-strength bolts. The high-strength bolt connection is easy to install and has a fast construction speed, which helps to shorten the construction period. The bolt connection makes the disassembly and replacement of the structure more convenient, which is conducive to later maintenance and inspection. The high-strength bolts have excellent shear and tensile properties to ensure the reliability and durability of the connection nodes. The exposed steel structure surface of the supporting structure is coated with a layer of anti-corrosion paint. The anti-corrosion paint effectively prevents oxidation and corrosion on the surface of the steel structure, significantly extending the service life of the structure. At the same time, it reduces the frequency of maintenance and replacement due to corrosion and reduces long-term maintenance costs. The supporting structure includes a main beam, which is made of H-shaped steel. The H-shaped steel has high bending stiffness to ensure that the structure has small deformation and high stability under load. A pair of parallel upper support beams are installed on the web of the main beam close to the wall. An upper reinforcement rod is fixedly installed between the two upper support beams, and the free end of the upper support beam is fixed to the wall.
[0008] A pair of parallel lower support beams are installed on the bottom surface of the main beam, and a lower reinforcement rod is fixedly installed between the two lower support beams.
[0009] The bottom surface of the main beam is located between the two lower supporting beams and is installed with a horizontal lower cantilever beam. The lower part of the free end of the lower cantilever beam is installed with an oblique brace connected to the lower reinforcement rod. The oblique brace is made of rectangular steel pipe. The oblique brace, the lower cantilever beam and the main beam form a triangular structure, which can effectively disperse and transfer the load and improve the overall stability and lateral force resistance of the structure.
[0010] The upper surface of the lower cantilever beam is supported by an upper cantilever beam through a number of web bars. The upper cantilever beam and the lower cantilever beam are made of I-shaped steel. The I-shaped steel has high bending stiffness, which ensures that the structure has small deformation and high stability under load. The combination of different types of steel materials optimizes the load and force of each part, thereby improving the bearing capacity of the overall structure. One end of the upper cantilever beam is fixed to the upper surface of the main beam, and an operating table is installed on the main beam. Two adjacent operating tables are connected by a connecting plate and fastening bolts.
[0011] Furthermore, a positioning rail is fixed to the lower surface of the operating table on the side of the upper cantilever beam, and the positioning rail cooperates with the positioning bolts installed on one side of the upper cantilever beam to fix the operating table, that is, the positioning rail is fixed to the lower surface of the operating table, and the positioning bolts pass through the positioning rail and are installed on the upper cantilever beam; a slide rail with rollers installed inside is fixed to the other side of the upper cantilever beam, and the sliding surface of the slide rail is flush with the upper surface of the upper cantilever beam and are on the same horizontal plane.
[0012] A method for using a high-altitude cantilever steel structure support assembly comprises the following steps: S1: Install two sets of upper support beams and lower support beams on the wall to ensure that they are firmly fixed. Through precise positioning and fixing, the installation height of each upper support beam and each lower support beam is consistent to provide a stable foundation.
[0013] S2: Fix the main beam on the upper supporting beam and the lower supporting beam, and install the upper cantilever beam above the main beam and the lower cantilever beam below it, ensuring that the connection between the upper cantilever beam, the lower cantilever beam and the main beam is tight and seamless to form a solid frame.
[0014] S3: The web is fixedly installed between the upper cantilever beam and the lower cantilever beam. This component increases the rigidity and stability of the entire structure and ensures that the structure does not deform under load.
[0015] S4: Installing lower reinforcement rods between lower support beams and installing upper reinforcement rods between upper support beams further enhances the strength of upper and lower cantilever beams, enabling them to withstand greater loads.
[0016] S5: Install the diagonal brace between the lower middle section of the lower reinforcement rod and the lower free end of the lower cantilever beam to form a triangular structure. The stability of the triangular geometry can effectively disperse and transfer the load, thereby improving the overall stability and lateral force resistance of the structure.
[0017] S6: Move the positioning track under the operating table close to the upper cantilever beam, and place the operating table on the upper cantilever beam and the slide rail. When adjusting the position of the operating table, the operating table slides on the upper surface of the upper cantilever beam and the slide rail. Construction personnel can flexibly adjust the position of the operating table according to specific work requirements, so as to facilitate high-altitude operations. Determine the position of the operating table and use positioning bolts to fix the positioning track to the upper cantilever beam.
[0018] S7: Connect the two operating tables using the fastening bolts.
[0019] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a high-altitude cantilever steel structure support component and a method of using the same. By using H-shaped steel as the main beam, I-shaped steel as the upper cantilever beam and the lower cantilever beam, and rectangular steel pipes as the diagonal bracing rods, the combination of different types of steel materials optimizes the load-bearing and force-bearing aspects of each part. The fixed installation of the web increases the rigidity and stability of the overall structure, ensuring that no deformation occurs under the action of load. The triangular structure formed by the diagonal bracing rods, the lower cantilever beam and the main beam improves the overall stability and lateral force resistance of the structure by effectively dispersing and transferring the load. The high-strength bolt connection is simple and fast, and has excellent shear and tensile properties, ensuring the reliability and durability of the connection nodes. These designs and material selections significantly improve the load-bearing capacity and service life of the high-altitude cantilever steel structure support component.
[0020] In the present invention, the exposed steel structure surface of the supporting structure is coated with an anti-corrosion paint, which effectively prevents oxidation and corrosion of the steel structure surface, significantly prolongs the service life of the structure, reduces the frequency of repairs and replacements due to corrosion, and reduces long-term maintenance costs. The use of high-strength bolt connections makes installation simple and quick, helps shorten the construction period, and makes disassembly and replacement of the structure more convenient, which is conducive to later maintenance and overhaul.
[0021] In the present invention, the design of the operating platform enables it to slide freely in the slide rail. Construction personnel can flexibly adjust the position of the operating platform according to specific work requirements, thereby making it more convenient to perform aerial work and improving work efficiency. The shell installed on the side of the upper cantilever beam and the rollers evenly distributed inside it reduce the friction of the operating platform when it moves on the slide rail, making the movement smoother and more labor-saving, improving the smoothness of the operating platform during movement, reducing jams and resistance, and ensuring the safety of aerial work.
