Description

Technical Field

[0001] The purpose of this utility model is to provide a steel structure support beam to solve the problems of insufficient load-bearing capacity, unstable connection and complicated installation of existing support beams, and to improve the performance and construction efficiency of support beams. Background Technology

[0002] In modern construction engineering, steel structure support beams, as key structural components, are widely used in various building projects, undertaking the important mission of bearing and transferring loads. However, with the continuous development of the construction industry and the increasing complexity of building structures, existing steel structure support beams have gradually revealed many problems that urgently need to be solved.

[0003] Traditional support beam structural designs have limitations, and their load-bearing capacity is inadequate when faced with complex and variable load conditions. Due to unreasonable design, localized stress concentration is prone to occur. When the localized stress exceeds the material's bearing capacity, the support beam will deform or even be damaged. This not only shortens the service life of the support beam but may also cause serious safety hazards, threatening the stability and safety of the entire building structure.

[0004] Some of the support beams are not securely connected, and during long-term use, they are prone to loosening and displacement due to various external forces and environmental factors. Once a problem occurs at the connection, the collaborative working ability between the support beams decreases, thereby affecting the stability of the entire building structure and posing a significant risk to the normal use of the building.

[0005] The installation of existing support beams is often cumbersome, requiring a significant investment of manpower and time. This complex process not only increases construction costs but also prolongs the construction period, hindering efficiency and failing to meet the demands of modern construction engineering for speed and efficiency. Utility Model Content

[0006] Purpose of the utility model: This utility model aims to provide a steel structure support beam that, through innovative structural design and reasonable component configuration, effectively solves the problems of insufficient load-bearing capacity, unstable connection, and cumbersome installation of existing support beams, comprehensively improves the performance and construction efficiency of support beams, and provides a more reliable and efficient structural support solution for building engineering.

[0007] Technical solution

[0008] A steel structure support beam mainly consists of three parts: the main support beam body, reinforcing connectors, and end fasteners. These three parts work together to achieve the various functions of the support beam.

[0009] The main support beam features a unique box-section design, assembled from four high-strength steel plates using a welding process. This box-section design offers excellent mechanical properties, effectively resisting bending and torsional forces. Inside the main support beam, meticulously designed transverse and longitudinal stiffening ribs are arranged in a honeycomb pattern. This honeycomb structure boasts extremely high space utilization and mechanical stability, effectively distributing loads and uniformly transferring concentrated stress throughout the beam structure, reducing localized stress concentration, and significantly improving the torsional and bending resistance of the main support beam. The stiffening ribs are joined to the high-strength steel plates using a double-bevel welding process. This welding method ensures connection strength and sealing, allowing the stiffening ribs and steel plates to form a unified whole, sharing the load. The outer surface of the main support beam undergoes a special hot-dip galvanizing anti-corrosion treatment. The hot-dip galvanized layer can effectively isolate moisture, oxygen and corrosive substances in the external environment, improve the corrosion resistance of the main support beam, thereby extending its service life and reducing maintenance costs. The ratio of the side length to the wall thickness of the box section of the main support beam is within 2 to optimize the structural performance of the main support beam.

[0010] The reinforced connector is used to connect adjacent main support beams, enhancing connection stability and overall integrity. It comprises a central connecting block and two side connecting plates. The central connecting block is a cuboid structure with multiple reinforcing ribs arranged in a crisscross pattern. This crisscross pattern further enhances the central connecting block's strength and resistance to deformation, ensuring it can withstand significant external forces during connection. The side connecting plates are connected to the ends of the main support beams using high-strength bolts. Continuous trapezoidal anti-slip teeth are provided on the contact surface between the side connecting plates and the main support beams, with a tooth height of 5 mm and a tooth spacing of 5 mm. This special tooth design significantly increases the friction of the contact surface, effectively preventing relative slippage at the connection and improving connection reliability. Simultaneously, the high-strength bolts are equipped with anti-loosening nuts and spring washers. The anti-loosening nuts prevent loosening during long-term use, while the spring washers provide continuous preload, further ensuring the stability of the connection.

[0011] End fasteners are installed at both ends of the main support beam to securely fix the support beam to the foundation of the building structure. Each end fastener consists of a fixing plate and multiple anchor bolts. The fixing plate is welded to the end of the main support beam, ensuring a strong, integrated structure. Multiple bolt holes are provided on the fixing plate, through which the anchor bolts pass to securely connect the fixing plate to the building foundation. The anchor bolts are made of high-strength alloy steel with a strength grade not lower than [specific grade], providing sufficient anchoring force to ensure the reliability of the connection between the end fasteners and the building foundation. A rubber vibration damping pad is installed between the fixing plate and the building foundation. The rubber vibration damping pad has a Shore hardness of [X] and a thickness of [X] mm. The rubber vibration damping pad effectively absorbs and buffers the vibrations generated by the support beam under load, reducing the impact of vibrations on the building foundation. It also allows for some adjustment of the installation height and level of the support beam, reducing the difficulty of adjustment during installation.

[0012] Compared with existing technologies, the beneficial effects of this invention are: significantly improved load-bearing capacity: the box-section design of the main supporting beam and the internal honeycomb stiffening rib structure form a highly efficient mechanical load-bearing system. The honeycomb stiffening ribs can evenly distribute the load throughout the entire beam structure, greatly improving the torsional and bending resistance of the supporting beam, enabling it to withstand greater loads. At the same time, it reduces the occurrence of local stress concentration, extends the service life of the supporting beam, and provides more reliable support for the building structure.

[0013] Stable and reliable connections: The special design of the reinforced connectors, including the cross-mesh reinforcing ribs of the central connecting block, the trapezoidal anti-slip serrations of the side connecting plates, and anti-loosening measures for high-strength bolts, ensures the stability of the connection between adjacent supporting beams from multiple aspects. The anti-slip serrations increase the friction of the contact surfaces, preventing relative slippage at the connection points; the anti-loosening nuts and spring washers ensure the long-term stability of the bolted connections, effectively preventing loosening and displacement, and improving the stability of the entire building structure.

[0014] Easy and efficient installation: The design of the end fasteners allows the support beams to be easily and quickly fixed to the building foundation. The rubber vibration damping pads not only reduce the impact of vibration on the building foundation, but also adjust the installation height and level of the support beams to a certain extent, reducing the difficulty of adjustment during installation. At the same time, the reinforced structural design of the connectors facilitates on-site installation, reduces construction time and labor costs, improves construction efficiency, and better meets the needs of rapid construction in modern building projects.

[0015] Excellent corrosion resistance: The outer surface of the main support beam is hot-dip galvanized, forming a dense protective film that effectively resists corrosion from the external environment, extending the service life of the support beam and reducing maintenance costs. This allows the support beam to maintain good performance under various harsh environmental conditions, improving the durability and reliability of the building structure.

[0033] End fastener installation: Use hoisting equipment to lift the main support beam to the predetermined position and install the end fasteners. Securely connect the fixing plate to the building foundation with anchor bolts, and place rubber shock-absorbing pads. During installation, use measuring tools such as levels and theodolites to monitor and adjust the horizontality and verticality of the support beam in real time to ensure installation accuracy.

[0034] Connecting adjacent support beams: When connecting adjacent main support beams, precisely align the side connecting plates of the reinforcing connector with the ends of the main support beams, use high-strength bolts for connection, and install lock nuts and spring washers. During the connection process, tighten the bolts to the specified torque value to ensure the stability of the connection.

[0035] Inspection and Acceptance: After installation, a comprehensive inspection of the support beam's installation position, connection status, and various performance indicators will be conducted. The inspection will include checking the support beam's levelness and verticality, the tightening torque of the connecting bolts, and the compression of the rubber shock-absorbing pads. After ensuring the support beam installation meets design requirements and construction specifications, it will be accepted and put into use.
