Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building structures, and in particular to a welding-free aluminum alloy frame beam-column connection node and a construction method. Background Art

[0002] Aluminum alloy frames refer to structural systems with a certain shape and function, which are assembled through specific connection methods using aluminum alloy as the main structural components. They are widely used in fields such as architecture and aerospace. Aluminum alloy frame beams and columns can be connected in a variety of ways, but compared to steel structures, aluminum alloy has many shortcomings in welding applicability. The main reasons are as follows:

[0003] ① Oxidation problem: Aluminum is very easy to oxidize in the air, and a dense oxide film will quickly form on the surface. Its melting point is as high as 2054℃, which is much higher than the melting point of aluminum (about 660℃). During the welding process, this oxide film will block the fusion of the metals, resulting in poor welding quality and defects such as lack of fusion and slag inclusion.

[0004] ② Aluminum has a much higher thermal conductivity and specific heat capacity than steel. This leads to faster heat dissipation during welding, requiring a higher heat input to ensure sufficient melting of the weld metal. This increases the difficulty of welding and may result in significant weld deformation.

[0005] ③ Porosity is easily generated. When welding aluminum, the solubility of hydrogen in liquid aluminum is much higher than in solid aluminum. During the solidification process of the weld, hydrogen does not have time to escape, resulting in pores. At the same time, the hydrogen generated by the decomposition of impurities such as moisture and oil during welding is also a major cause of pore formation.

[0006] ④ Prone to thermal cracking. Aluminum alloys experience a sharp drop in strength and plasticity at high temperatures, making thermal cracking more likely to occur in the heat-affected zone during welding. Furthermore, the linear expansion coefficient of aluminum alloys is twice that of steel, leading to greater thermal stress during welding, which also increases the tendency for thermal cracking.

[0007] ⑤ Joint softening: After aluminum alloy welding, the heat-affected zone is prone to softening, which reduces the strength and hardness of the joint. This will seriously affect the performance of structural parts that require high strength. Summary of the Invention

[0039] Furthermore, a plurality of bolt holes are provided on the H-shaped aluminum alloy column, the H-shaped aluminum alloy beam I, the H-shaped aluminum alloy beam II, and the plurality of connecting parts.

[0040] The bolt holes on the H-shaped aluminum alloy column, H-shaped aluminum alloy beam I, and H-shaped aluminum alloy beam II correspond to the bolt holes on the connecting parts one by one.

[0041] Another object of the present invention is to provide a construction method based on a welding-free aluminum alloy frame beam-column connection node, comprising the following steps:

[0042] S1. Process the H-shaped aluminum alloy columns, H-shaped aluminum alloy beams I, H-shaped aluminum alloy beams II, and several connecting parts in the factory. After processing, the components are transported to the construction site.

[0043] S2. Install H-shaped aluminum alloy column 1.

[0044] When the H-shaped aluminum alloy column is the middle column, four aluminum alloy angle pieces V are relatively installed on both sides of the web of the H-shaped aluminum alloy column, and an aluminum alloy T-shaped piece is installed between each of the two aluminum alloy angle pieces V on the same side.

[0046] S3. Hoist the H-shaped aluminum alloy beam I to the designated location, and install the H-shaped aluminum alloy beam I on the H-shaped aluminum alloy column through two aluminum alloy angle pieces I, two aluminum alloy angle pieces II, four aluminum alloy angle pieces IV, and several bolts.

[0047] When the H-shaped aluminum alloy column is an intermediate column or a side column, two H-shaped aluminum alloy beams I are installed. When the H-shaped aluminum alloy column is a corner column, one H-shaped aluminum alloy beam I is installed.

[0048] S4. Hoist the H-shaped aluminum alloy beam II to the designated location, and connect the aluminum alloy angle piece V, the aluminum alloy T-shaped piece, and the four aluminum alloy angle pieces IV through four aluminum alloy angle pieces III, two aluminum plywood, and several bolts to install the H-shaped aluminum alloy beam II on the H-shaped aluminum alloy column.

[0049] When the H-shaped aluminum alloy column is an intermediate column, two H-shaped aluminum alloy beams II are installed. When the H-shaped aluminum alloy column is a side column or a corner column, one H-shaped aluminum alloy beam II is installed.

[0050] The technical effects of the present invention are undoubted, and the beneficial effects of the present invention are as follows:

[0051] ① The present invention provides a welding-free aluminum alloy frame beam-column connection node, which enhances the integrity, enables more uniform force transmission in the structure, effectively improves the overall mechanical properties and bearing capacity of the structure, and reduces the phenomenon of local stress concentration.

[0052] ② When installing the welding-free aluminum alloy frame beam-column connection node provided by the present invention, it is only necessary to fix the connecting parts to the beams and columns, without the need for a large amount of welding or other complicated processing operations on site, which can shorten the construction period to a limited extent and improve construction efficiency.

[0053] ③ The present invention does not require professional welding equipment and technicians, which reduces the construction difficulty and labor costs. In addition, there is no high-temperature welding operation during the construction process, and no pollution such as welding smoke and strong light will be generated. It improves the construction environment and reduces safety hazards.

[0054] ④ The construction quality of bolted connections is easier to inspect and control. Tools such as wrenches can be used to ensure that the bolts are tightened so that the torque meets the requirements, thereby ensuring the connection strength and avoiding internal defects such as slag inclusions, pores, and incomplete penetration caused by improper welding process parameters and operational errors.

[0055] ⑤ When aluminum alloy frames need to be modified, repaired, or replaced, bolted connections are easy to disassemble without damaging beams and columns. However, welded connections require cutting and grinding, which can damage the components. After repeated disassembly and reassembly, as long as the bolts and connectors are intact, the connection will maintain good performance. However, welded repairs may experience performance degradation.

[0056] ⑥ The present invention will not change the metallographic structure of the aluminum alloy material due to the high welding temperature, resulting in a decrease in material properties such as reduced strength and toughness, nor will it generate residual stress in the connection area like welding, effectively improving the reliability and service life of the structure.
