Description

Technical Field

[0001] This utility model relates to the field of steel structures, and more specifically, to a steel structure column with high thermal insulation properties. Background Technology

[0002] Steel structural columns, as core load-bearing components in modern architecture and engineering, are widely used in high-rise buildings, industrial plants, bridges, and other applications due to their high strength, lightweight, and ease of construction. However, with the increasing standards for building energy conservation and safety, the problems arising from their inherent characteristics have gradually become prominent, becoming a focus of industry attention.

[0003] Existing steel structure columns have the following drawbacks in practical use. On the one hand, traditional steel structure columns mostly use external wall insulation. Although this method is relatively convenient to construct, it has significant defects. Thermal bridges are easily formed between the insulation layer and the steel column, causing heat to be rapidly conducted through the steel column, which greatly reduces the overall insulation efficiency of the building and increases energy consumption. At the same time, the external insulation layer is affected by environmental factors (such as sun exposure and wind and rain erosion), which are prone to cracking and falling off, further weakening the insulation effect and requiring frequent maintenance. On the other hand, the traditional insulation layer and steel column structure are relatively independent and cannot work together to bear the load, resulting in uneven load distribution. Local stress concentration can easily cause damage to the insulation layer and shorten its service life. In addition, traditional steel column insulation construction often relies on welding, bonding and other processes, which not only have high requirements for the construction environment and personnel skills, but are also easily limited by humidity, temperature and other conditions, making it difficult to control construction errors and posing hidden dangers such as loose insulation layer adhesion and residual thermal bridges.

[0004] How to invent a steel structure column with high thermal insulation to solve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a steel structure column with high thermal insulation properties, aiming to solve the problems mentioned in the background.

[0006] This utility model is implemented as follows: This utility model provides a steel structure column with high thermal insulation performance, including a rectangular tube, several steel profiles, and a connecting plate. The rectangular tube and the connecting plate are fixed together by positioning bolts. After the rectangular tube and the connecting plate are installed, they are fixed to the several steel profiles by connecting bolts. The rectangular tube is provided with an insulation component, which includes an inner support column, a main insulation board, and two side insulation boards. There are two main insulation boards and two side insulation boards. The bottom of the main insulation board is provided with a baffle. The side wall of the main insulation board is provided with a positioning post. The main insulation board has a sliding groove. The two sides of the side insulation board are provided with limiting strips that match the sliding groove. The top of the inner support column is provided with a first buckle groove. The side wall of the rectangular tube is provided with a positioning hole that matches the positioning post. Corresponding to the first buckle groove, the side insulation board is provided with a third buckle groove, and the main insulation board is provided with a second buckle groove. The bottom of the inner support column is provided with a boss. The inner support column has a receiving cavity. The boss has an installation groove inside, and a plug is threaded into the installation groove.

[0007] Preferably, the baffles on different main insulation boards are centrally symmetrically distributed.

[0008] Preferably, when installing the insulation components, first, install the main insulation panels on both sides, and then insert the side insulation panels along the sliding grooves. At this time, the two main insulation panels and the two side insulation panels form a frame. Finally, insert the inner support column into the frame.

[0009] Preferably, the bottom hollow area of ​​the frame matches the boss.

[0010] Preferably, the distance between the top of the baffle and the top of the main insulation board is equal to the height of the side insulation board, and the height of the inner support column is equal to that of the side insulation board.

[0011] Preferably, the cavity is filled with thermal insulation material particles, and the main insulation board and the side insulation board are made of the same material.

[0012] The beneficial effects of this utility model are: Existing steel columns mostly use external wall insulation, which is prone to thermal bridging. This structure, however, uses a multi-layer insulation system of "insulation frame + air layer + granular filling" to block the heat conduction path from the inside, significantly reducing the overall thermal conductivity and improving the insulation effect. Most traditional steel columns rely on external fire-retardant coatings for fire protection, which are prone to peeling and have limited fire resistance time. This structure uses non-combustible or flame-retardant materials for internal filling, forming a composite structure of "metal shell + fireproof core material", which effectively slows down the temperature rise of the steel column in a fire, significantly extends the fire resistance time, and improves building safety.

[0013] The insulation components employ a mortise and tenon joint and interlocking design to transfer the load step by step, disperse pressure, avoid localized damage, and improve the overall structural stability and durability. Traditional steel column insulation construction often requires complex processes such as welding and bonding, which are easily affected by the environment and have large errors. This structure adopts a modular design and physical interlocking connection, eliminating the need for welding and adhesives. The installation process is simple and quick, reducing construction steps and time, and lowering construction difficulty and labor costs. Traditional external wall insulation occupies extra space, affecting the building's usable area and appearance. This structure integrates the insulation layer internally, without occupying external space. The outer wall of the steel column can be directly decorated, meeting the building's space requirements and enabling diverse appearance designs to suit various architectural scenarios.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example, refer to Figures 1-6 A high-insulation steel structure column includes a rectangular tube 1, several-shaped steel profiles 2, and a connecting plate 3. The rectangular tube 1 and the connecting plate 3 are fixed together by positioning bolts 4. After the rectangular tube 1 and the connecting plate 3 are installed, they are fixed to the several-shaped steel profiles 2 by connecting bolts 41. The rectangular tube 1 is equipped with an insulation component, which includes an inner support column 5, a main insulation board 6, and a side insulation board 7. The rectangular tube 1 serves as the main load-bearing component, bearing axial loads and bending moments. Its internal cavity provides installation space for the insulation component. The several-shaped steel profiles 2 are connected to the rectangular tube 1 through the connecting plate 3 to enhance the overall rigidity of the column. It is suitable for scenarios requiring lateral support (such as frame structure nodes). The insulation component is filled inside the rectangular tube 1. Through the splicing of the main insulation board 6, the side insulation board 7, and the inner support column 5, a continuous insulation layer is formed, blocking the heat conduction path of the metal wall of the rectangular tube 1.

[0019] Two main insulation boards 6 and two side insulation boards 7 are provided. A baffle 62 is provided at the bottom of the main insulation board 6, and positioning posts 61 are provided on the side walls of the main insulation board 6. A sliding groove 63 is provided on the main insulation board 6. Limiting strips 71 matching the sliding grooves 63 are provided on both sides of the side insulation board 7. The side insulation board 7 is embedded into the sliding grooves 63 of the main insulation board 6 through the limiting strips 71 on both sides, forming a "drawer-type" sliding connection. No adhesive or bolts are required; assembly is quick through physical interlocking, adapting to on-site construction errors. A snap-fit ​​groove 54 is provided at the top of the inner support column 5, and the side walls of the rectangular tube 1 are provided with... The positioning post 61 is matched with the positioning hole 11. During installation, the positioning post 61 of the main insulation board 6 is inserted into the positioning hole 11 on the side wall of the rectangular tube 1 to achieve the initial fixation of the insulation board and the steel column and avoid displacement. The side insulation board 7 corresponding to the first groove 54 is provided with the third groove 72 and the main insulation board 6 is provided with the second groove 64. The setting of each groove makes it easy to pull out each part. The bottom of the inner support column 5 is provided with the boss 51. The inner support column 5 is provided with the receiving cavity 50. The boss 51 is provided with the installation groove 52. The installation groove 52 is threaded with the plug 53.

[0020] It should be noted that the baffles 62 on the different main insulation boards 6 are centrally symmetrically distributed, providing a supporting base for the side insulation boards 7 and providing positioning space for the bosses 51.

[0021] When installing the insulation components, first, install the main insulation panels 6 on both sides, and then insert the side insulation panels 7 along the sliding grooves 63. At this time, the two main insulation panels 6 and the two side insulation panels 7 form a frame. Finally, insert the inner support column 5 into the frame.

[0022] It should be noted that the bottom hollow area of ​​the frame matches the boss 51, forming a "mortise and tenon" joint when inserted. This not only fixes the vertical position of the inner support column 5, but also distributes the bottom load, preventing the insulation board from cracking due to pressure. The distance between the top of the baffle 62 and the top of the main insulation board 6 is equal to the height of the side insulation board 7, ensuring that the upper and lower surfaces of the entire frame are flush after the side board is inserted, facilitating the insertion of the inner support column 5. The height of the inner support column 5 and the side insulation board 7 are equal. The cavity 50 is filled with insulation material particles (such as expanded perlite and aerogel particles). The air layer between the particles further reduces heat conduction. At the same time, fluid insulation material (such as foamed polyurethane) can be injected through the mounting groove 52 of the boss 51 to fill gaps and eliminate thermal bridges. The main insulation board 6 and the side insulation board 7 are made of the same material and use high-efficiency insulation materials (such as rock wool and polyurethane). The same material is continuously spliced ​​to form a closed insulation layer on all four sides, blocking the heat conduction between the metal wall of the rectangular tube 1 and the outside.

[0023] The working principle of this high-insulation steel structure column is as follows: The rectangular tube 1 serves as the main structural component. Its hollow cross-section design satisfies the bending and torsional strength requirements, while the internal cavity provides installation space for the insulation components. Several steel profiles 2 form a support column with the rectangular tube 1 through the connecting plate 3. After being fixed by the connecting bolt 41, it can bear the lateral shear force (such as horizontal wind load and seismic action), enhance the node stiffness of the steel column in the frame structure, and avoid the overall structural instability caused by the deformation of a single column.

[0024] When installing the insulation components, first, install the main insulation panels 6 on both sides, and then insert the side insulation panels 7 along the sliding grooves 63. At this time, the two main insulation panels 6 and the two side insulation panels 7 form a frame. Finally, insert the inner support column 5 into the frame.

[0025] By inserting the positioning post 61 into the positioning hole 11 of the rectangular tube 1, the main insulation board 6 is first fixed to the inner wall of the steel column, and the side insulation board 7 is slidably engaged with the sliding groove 63 through the limiting strip 71, forming a closed "rectangular insulation frame". No on-site welding or adhesive is required; the physical structure allows for rapid positioning, avoiding the problems of insulation layer cracking or thermal bridge exposure caused by construction errors in traditional processes. The tiny gap (air layer) between the frame and the inner wall of the rectangular tube 1, along with the insulation board material itself (such as the low thermal conductivity of rock wool), jointly blocks the heat conduction path. After the inner support post 5 is inserted into the insulation frame, the insulation components are locked as a whole through the tenon and mortise joint between the bottom boss 51 and the hollow area of ​​the frame, providing support for the entire insulation frame. Simultaneously, the insulation particles (such as expanded perlite) in the receiving cavity 50 further reduce heat conduction through the static air layer between the particles, while the insulation material injected into the installation groove 52... Polyurethane foam can fill all gaps and eliminate "point contact" thermal bridges. The materials filled inside the rectangular tube 1 (such as rock wool, glass wool, and foamed concrete) are mostly non-combustible or flame-retardant materials and are wrapped by steel to form a composite structure of "metal shell + fireproof core material". In a fire, heat must first penetrate the steel (slow heat conduction) and then be transferred to the insulation layer, which slows down the heating rate of the steel column and significantly extends the fire resistance time. In addition, the insulation layer directly covers the inside of the steel, blocking the heat conduction path through the steel cross section (especially the large metal parts such as the web and flange of the rectangular tube 1). The steel only acts as the "shell" to transfer heat, while the insulation material filled inside can greatly reduce the overall thermal conductivity. The insulation layer is completely located inside the steel column and does not occupy external space. The outer wall of the steel column can be directly used as a decorative surface (such as painting or tiling) or seamlessly connected with the curtain wall, taking into account both functionality and aesthetics.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "join," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
