Description

Technical Field

[0001] This patent relates to the field of steel components, and in particular to an end plate and a steel structure module. Background Technology

[0002] Steel structures are widely used in the construction industry due to their high strength, durability, and ease of construction, especially in temporary structures. Typical temporary steel structures include excavation and lateral support (ELS) systems and temporary steel platforms. The former uses support members, columns, and other components to resist lateral soil pressure, ensuring the safety of excavation construction; the latter provides a stable working surface for large machinery (such as crawler cranes). However, these temporary structures are dismantled after the permanent works are completed, resulting in a large amount of steel structural components becoming scrap. Statistics show that the global construction industry generates approximately 15%-20% of the total steel used in steel structures annually due to temporary works, not only wasting resources but also exacerbating carbon emissions due to the high energy consumption of steel smelting.

[0003] Traditional steel structure connections primarily employ on-site welding. While welding achieves high-strength bonding through high-temperature fusion, it presents significant drawbacks: First, welded joints are non-removable permanent connections, requiring destructive methods such as cutting, grinding, and severing for dismantling, rendering the components unusable. Second, the welding process easily induces steel deformation, residual stress, and microcracks, affecting structural performance. Third, welding quality depends on manual operation, necessitating specialized equipment and protective measures, resulting in high construction costs and occupational health risks. Fourth, weld quality must be inspected and confirmed before proceeding to the next construction step, a time-consuming process. Furthermore, the lack of standardization in existing steel structure designs leads to significant differences in component dimensions and connection methods across different projects, further hindering the versatility of recycled steel.

[0004] To solve, or at least partially solve, the aforementioned technical problems, the first aspect of this patent provides an end plate, comprising:

[0005] The main body can be connected to the end of the first steel structural member;

[0006] A connecting part is provided on the main body for connecting to the connecting part of the other end plate on the end connected to the second steel structure member;

[0007] The position of the connecting part on the body avoids the vertical projection of the first steel structural member and the second steel structural member on the body.

[0008] A further technical solution could be that the first steel structural component and the second steel structural component have different specifications.

[0009] A further technical solution may be that the connecting part includes:

[0010] Multiple screw holes are distributed on the body to be used to connect the end plate of the second steel structural member to the screw holes by bolts.

[0012] The rectangular trajectory is set outside the outer contour of the projection of the first steel structural member, or...

[0013] The rectangular trajectory extends within the range of the outer contour of the projection of the first steel structural member.

[0014] A further technical solution could be that both the first steel structural member and the second steel structural member are I-beams.

[0022] Multiple first connecting plates are arranged sequentially along the length of the first steel structural member and connect the sides of the first steel structural member and the third steel structural member.

[0023] A further technical solution could be that the steel structure module also includes:

[0024] The fourth steel structural member is arranged side by side with the second steel structural member;

[0025] The third steel structural member and the fourth steel structural member are connected by another end plate;

[0026] The connecting plate is also used to connect the end plate of the third steel structural member and the fourth steel structural member;

[0027] The steel structure module also includes: multiple second connecting plates, each of which is distributed sequentially along the length of the second steel structure member and connects the side of the second steel structure member and the fourth steel structure member.

[0028] A further technical solution could be that the first steel structural member, the third steel structural member, the second steel structural member, and the fourth steel structural member form an integral structure through the connecting plate located between the end plates, each with its own end plate.

[0029] A further technical solution could be that the first steel structural member is a reusable component, and a marking attachment is provided on the first steel structural member to identify its identity.

[0030] A further technical solution could be that the marking accessory is a stainless steel sheet with a QR code on it.

[0031] This patent proposes an end plate and a steel structure module. By connecting the end plates, the recyclable steel structure components can be modularized and standardized, thereby improving the reuse rate of steel structure components, significantly promoting environmental protection and the circular economy, reducing the amount of scrap steel generated, and reducing carbon emissions.

[0052] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0053] The inventors discovered that, although the industry is increasingly recognizing the importance of steel structure reuse, existing technologies still face multiple obstacles:

[0054] Connection methods restrict recycling: The current situation, dominated by welding processes, makes component disassembly difficult and makes it hard to guarantee the integrity of recycled steel;

[0055] Insufficient standardization: Non-uniform component specifications and connection designs make it difficult to adapt recycled steel to the needs of new projects;

[0056] Lack of a recycling system: The lack of a comprehensive management system covering production, installation, dismantling, and testing makes it difficult to trace the quality and evaluate the performance of recycled steel.

[0057] Economic bottleneck: Traditional recycling processes require a large investment of manpower, warehousing and transportation resources, making the cost far higher than directly purchasing new steel.

[0058] The aforementioned issues have resulted in a steel structure reuse rate that has remained below 30% for a long time, contradicting the construction industry's goal of low-carbon transformation. Therefore, a technological solution is urgently needed that, while ensuring structural performance, achieves efficient disassembly, non-destructive recycling, and cross-project reuse of steel structures through modular connection design and standardized management, thereby reducing scrap steel generation and carbon emissions.

[0059] Implementation Method 1

[0060] To address the aforementioned problems, the first aspect of this embodiment discloses an end plate 1, such as... Figure 1 and Figure 2 As shown, it includes:

[0061] The main body 11 can be connected to the end of the first steel structural member 2;

[0062] The connecting part 12 is provided on the body 11 and is used to connect with the connecting part of the other end plate 1 on the end connected to the second steel structure 3.

[0063] The position of the connecting part 12 on the body 11 avoids the vertical projection of the first steel structural member 2 and the second steel structural member 3 on the body 11.

[0064] The body 11 is the main structure of the end plate 1, providing a flat surface for fixing to the end of the steel structure and serving as the carrier of the connecting part 12. The body 11 receives the load transmitted by the steel structure. Specifically, in this embodiment, the connecting part 12 can be a screw hole. When the first steel structure 2 and the second steel structure 3 are connected, the screw holes on their respective end plates 1 correspond one-to-one and are connected and fixed by bolts. In other embodiments, as an alternative, the connecting part 12 can also be a tenon. When the first steel structure 2 and the second steel structure 3 are connected, the tenons on their respective end plates 1 correspond one-to-one. The tenon is inserted from the tenon of one end plate 1 and passes through to the other end plate 1, and is fixed from one side of the other end plate 1 by a locking tenon. Compared with the prior art, traditional welding connections directly fuse the ends of components, resulting in irreversible disassembly and material damage. This embodiment, however, achieves a completely reversible modular assembly method through indirect connection via end plates 1, enabling non-destructive disassembly and reuse of steel structure components.

[0065] It should be noted that, in this embodiment, the area where the vertical projection of the first steel structural member 2 on the body 11 is located can be understood as the area where the ends of the body 11 and the first steel structural member 2 are connected. Therefore, if the connecting part is located within this vertical projection, it may affect the stability of the connection between the body 11 and the first steel structural member 2. Therefore, in this embodiment, to solve the above problem, the position of the connecting part 12 on the body 11 avoids the vertical projections of the first steel structural member 2 and the second steel structural member 3 on the body 11. The vertical projection of the first steel structural member 2 on the body 11 refers to the area where the cross-section of the first steel structural member 2 is located on the corresponding plane of the body 11. The vertical projection of the second steel structural member 3 on the body 11 refers to the area where the cross-section of the second steel structural member 3 is located on the corresponding plane of the body 11. In this embodiment, the connecting part 12 is positioned to avoid these projection areas, ensuring that the connecting part 12 is not covered or blocked by the solid parts of the steel structural members (the first steel structural member 2 and the second steel structural member 3), thus preventing the connecting part 12 from affecting the connection strength between the body 11 and the first steel structural member 2. The avoidance design of this connection part 12 can improve the universal adaptability of the standardized end plate 1; moreover, the modular end plate 1 structure simplifies the on-site installation process, reduces the dependence on professional welding equipment and personnel, and provides a feasible technical path for the recycling of steel structures.

[0066] 1. It is worth mentioning that when setting the specific position of the connecting part 12, the following situations need to be considered (taking the connecting part 12 as a screw hole as an example): spatial interference between two adjacent screw holes on the same end plate 1, that is, ensuring that there is sufficient distance between two adjacent screw holes to meet the needs of bolt installation and the needs of operating space when installing bolts.

[0067] 2. Spatial interference between the screw hole and the first steel structural component 2, that is, to ensure that there is sufficient distance between the screw hole and the edge of the end plate to meet the requirements of bolt installation.

[0068] The second aspect of this embodiment also discloses a steel structure module a, comprising:

[0069] The first steel structural member 2 has an end plate 1 as described above on its end.

[0070] The second steel structural member 3 has another end plate 1 on its end, and the end plate 1 of the first steel structural member 2 and the end plate 1 of the second steel structural member 3 are connected to each other.

[0071] This embodiment constructs a modular connection system using standardized end plates 1. Specifically, after the end plate 1 is installed on the end of the first steel structural member 2, a unified connection interface is formed. The bolt hole distribution of the end plate 1 is adjusted according to the projection position of adjacent steel structural members to avoid spatial interference. When it is necessary to connect the second steel structural member 3, the corresponding end plate 1 at its end is precisely aligned with the end plate 1 of the first steel structural member 2 using bolts.

[0072] In some specific embodiments, the end plate 1 body 11 is a rectangular steel plate. The body 11 is fixed to the end face of the first steel structural member 2 (e.g., an I-beam) by welding or bolting. The connecting part 12 includes a plurality of screw holes distributed along the peripheral area of ​​the body 11, forming a rectangular or polygonal array surrounding the projection of the end face of the first steel structural member 2. When the end plate 1 is bolted to another end plate 1 connected to the end face of the second steel structural member 3 (e.g., another I-beam), these screw holes are located outside the vertical projections of the first and second I-beams on the body 11. For example, if the webs and flanges of the first and second I-beams form an "H"-shaped projection area on the body 11, the screw hole array is arranged around the periphery of the "H"-shaped area, ensuring that the bolts do not interfere with any part of the I-beams when passing through the screw holes. Thus, an unobstructed connection between the end plates 1 is achieved, facilitating the installation and removal of bolts.

[0073] In existing technologies, steel structure connections rely on on-site welding to form permanent joints. Dismantling requires cutting and damaging the steel structural components, which is cumbersome, time-consuming, and prone to deformation in the heat-affected zone during welding. This embodiment uses mechanical end plate connections, enabling rapid on-site installation and dismantling, reducing on-site processing needs and shortening the construction cycle. The connection interface is separate from the steel structural component body 11, and the dismantling process does not damage the main structure, preserving the integrity of the steel. This achieves non-destructive dismantling and cross-project reuse of steel structural components, solving the problem of component scrapping caused by irreversible welding connections and avoiding deformation, residual stress, and safety hazards caused by welding. In addition, the standardized end plate 1 design eliminates the limitations of component specification differences on reuse, and the modular connection structure simplifies the assembly and disassembly process, reducing the difficulty of warehousing management.

[0074] In some preferred embodiments, the first steel structural member 2 and the second steel structural member 3 have different specifications, indicating that this technology has a wide range of applications.

[0075] As can be seen from the above, the end plate 1 includes a body 11 and a connecting part 12. The connecting part 12 is disposed on the body 11, and its position avoids the vertical projection of the first steel structural member 2 and the second steel structural member 3 onto the body 11. When the specifications of the first steel structural member 2 and the second steel structural member 3 are different, a solution is needed to effectively achieve the connection, solve the connection adaptation problem of steel structural members of different specifications, and realize the universal connection of irregular components. By adopting the end plate 1 described above, its connecting part 12 is disposed on the body 11, and the position of the connecting part 12 on the body 11 avoids the vertical projection of the first steel structural member 2 and the second steel structural member 3 onto the body 11. Therefore, even if the specifications of the first steel structural member 2 and the second steel structural member 3 are different, and their projection sizes on the body 11 are different, the position design of the connecting part 12 ensures that it is located in a common area outside the two different projection areas, thereby providing a standardized connection interface. This design allows the same type of end plate 1 to be used to connect various steel structural components of different specifications, solving the problem of connection compatibility between steel structural components of different specifications, improving the versatility of the connection, and thus accelerating the construction progress of the project.

[0076] The following two examples illustrate this point:

[0077] Example 1: The first steel structural member 2 is an I-beam (e.g., UC 305x305x137), and the second steel structural member 3 is an I-beam (e.g., UC 305x305x198).

[0078] Example 2: The first steel structural component 2 is a box-shaped steel (e.g., 200×200×10), and the second steel structural component 3 is a channel steel (e.g., C160).

[0079] In the two examples above, the placement of the connecting part 12 follows these rules: the position of the connecting part 12 on the body 11 avoids the vertical projections of the first steel structural member 2 and the second steel structural member 3 onto the body 11. The specific placement of the connecting part 12 requires adjustment of the cross-sectional dimensions of the steel structural members to ensure the stability of the bolted connection.

[0080] Implementation Method 2

[0081] This embodiment proposes an end plate 1 and a steel structure module a. This embodiment is a further improvement based on the first embodiment. In this embodiment, the specific arrangement of the connecting portion 12 is further defined. Specifically, as follows... Figure 1 and Figure 2 As shown, the connecting part 12 includes:

[0082] Multiple screw holes are distributed on the body 11 to be connected to the screw holes of the end plate 1 of the second steel structural member 3 by bolts.

[0083] Specifically, the screw holes are machined into standardized diameters and evenly distributed on the surface of the end plate 1 body 11. The screw holes on the end plates 1 of the first steel structural member 2 and the second steel structural member 3 correspond one-to-one. After the bolts pass through the corresponding screw holes, they engage with the nuts to form a detachable connection. When disassembly is required, simply loosening the nuts separates the end plate 1 from the second steel structural member 3, without requiring cutting or damaging the body 11 or the steel structural member. The distribution range of the screw holes is controlled outside the projection area of ​​the first steel structural member 2 to avoid interference with existing components during bolt tightening. When adapting to different specifications of the second steel structural member 3, the number, spacing, or arrangement trajectory of the screw holes can be adjusted to allow the end plate 1 to meet various standardized connection requirements. Moreover, the standardized screw hole layout design enables the end plate 1 to adapt to connection requirements in different engineering scenarios, reducing the difficulty of secondary processing of recycled components and providing a basic connection guarantee for the steel structure recycling system.

[0084] Bolted connections are a reversible mechanical connection method, allowing for the installation and disassembly of components without damaging them. The distribution of multiple bolt holes provides sufficient connection points, ensuring the strength and stability of the connection. Replacing traditional welding with bolted connections avoids the high temperatures, deformation, and residual stress problems associated with welding, reduces the skill requirements for construction workers, and improves construction safety. Furthermore, the ease of disassembly of bolted connections allows steel structural components to be easily removed from one project and reused in another, reducing scrap steel generation and lowering resource consumption and carbon emissions.

[0085] In some preferred embodiments, at least some of the screw holes are distributed at intervals along a rectangular trajectory on the connecting surface of the end plate 1.

[0086] The screw holes are arranged along a rectangular trajectory at fixed intervals. This rectangular distribution forms a structured connection layout, facilitating alignment with corresponding screw holes on the other end plate 1. Furthermore, this arrangement optimizes the stress path, improves connection strength and space utilization, and avoids stress concentration caused by densely packed screw holes.

[0087] Specifically, in some embodiments, such as Figure 6 As shown, the rectangular trajectory is set outside the outer contour of the projection of the first steel structural member 2. This arrangement ensures that there is space between the bolt connection area and the connection area of ​​the first steel structural member 2, avoiding physical interference during connection. In other embodiments, such as Figure 7As shown, the rectangular trajectory extends within the outer contour of the projection of the first steel structural member 2. This arrangement is suitable for situations requiring a more compact connection layout. The aforementioned method of limiting the screw hole positions, combined with the distribution pattern of the rectangular trajectory, ensures that the screw hole arrangement effectively connects to the end plate 1 of the second steel structural member 3 while avoiding conflict with the connection area of ​​the first steel structural member 2 on the end plate 1, thus improving connection reliability and construction convenience. Furthermore, this arrangement allows the screw holes to avoid the projection of the steel structural member, reducing positioning errors during installation.

[0088] In some preferred embodiments, both the first steel structural member 2 and the second steel structural member 3 are I-beams.

[0089] By defining the first steel structural member 2 and the second steel structural member 3 as I-beams, a design for an end plate 1 specific to a particular member type is provided. I-beams have a standard cross-sectional shape, including a web and flanges. Specifying the member type as an I-beam allows the design of the end plate 1 to be optimized for the geometric characteristics of the I-beam. For example, the specific position and layout of the connection part 12 on the body 11 of the end plate 1 can be determined to ensure that the connection part 12 effectively avoids the projection area of ​​the I-beam cross-section on the end plate 1, while achieving a reliable connection with the end of the I-beam. This limitation reduces the design complexity caused by the diversity of member types, facilitates the standardized production and application of the end plate 1, and improves the connection efficiency and interchangeability of members when using I-beams as structural components.

[0090] Furthermore, limiting the first steel structural member 2 and the second steel structural member 3 to I-beams provides a specific and feasible component application scenario for the end plate 1 connection scheme, making the design and connection method of the end plate 1 more explicit and concrete. Specifically, in this embodiment, the parameters of the end plate 1 can be specifically designed according to the existing I-beam models to achieve standardized design of the end plate 1, enabling flexible splicing of steel structural members of different specifications and improving connection efficiency; the standardized bolt hole layout can adapt to a variety of steel structural members, shorten on-site construction time, support multiple disassembly and reassembly of temporary structures, and significantly improve the reuse rate of steel.

[0091] Accordingly, for high-demand scenarios involving I-beams, a standardized end plate design can be provided to adapt to general-purpose steel structural components. Furthermore, using existing general-purpose I-beam specifications facilitates the reuse of steel structures, reduces steel production needs, lowers resource consumption and waste disposal costs, and achieves sustainable development in the construction industry.

[0092] Implementation Method 3

[0093] This embodiment is a further improvement based on the first or second embodiment, and the improvement is that, for example... Figure 3 and Figure 4 As shown, the steel structure module a further includes:

[0094] The third steel structural member 4 is arranged side by side with the first steel structural member 2;

[0095] A connecting plate 5 is disposed between the two end plates 1, and the connecting plate 5 is used to connect the end plates 1 of the third steel structural member 4.

[0096] The inventors discovered that after the first steel structural member 2 and the second steel structural member 3 are connected to form a basic unit through their respective end plates 1, the basic unit only provides a connection between the two steel structural members and cannot directly connect to the third steel structural member 4 which is arranged side by side with the first steel structural member 2, thus limiting the expansion capability of the modular structure.

[0097] Therefore, in this embodiment, a third steel structure member 4 is arranged parallel to the first steel structure member 2, and a connecting plate 5 is provided between the end plate 1 of the first steel structure member 2 and the end plate 1 of the second steel structure member 3. The connecting plate 5 is used to connect the end plate 1 of the third steel structure member 4. Thus, the end of the third steel structure member 4 can be connected to the basic connection unit through the connecting plate 5, realizing the ability to connect multiple parallel steel structure members at the same connection node. The introduction of the third steel structure member 4 expands the width of the module, and the connecting plate 5 acts as a bridge, enabling the parallel third steel structure members 4 to be effectively integrated into the connection system composed of the first and second steel structure members 3, improving the combination flexibility and scalability of the steel structure module a. It is worth mentioning that the connecting plate 5 adopts the same design standard as the end plate 1, thereby enabling the connecting plate 5 to connect with the end plate 1.

[0098] In some preferred embodiments, such as Figure 3 As shown, the steel structure module a further includes:

[0099] Multiple first connecting plates 6 are distributed sequentially along the length of the first steel structural member 2 and connect the sides of the first steel structural member 2 and the third steel structural member 4.

[0100] By distributing multiple first connecting plates 6 along the length direction and connecting the sides of the first steel structural member 2 and the third steel structural member 4, a connection along the length direction is established between the first steel structural member 2 and the third steel structural member 4. This connection method improves the overall stiffness between the two parallel steel structural members, enhances stability, restricts their relative movement along the length direction, and limits deformation. Thus, it solves the problem of insufficient connection along the length direction of parallel steel structural members and addresses the issue of decreased stability. Connecting the first and third steel structural members 4 side-by-side using connecting plates adapts to complex structural requirements and can form multi-directional symmetrical structures.

[0101] In some preferred technical solutions, such as Figure 3 , Figure 4 and Figure 5 As shown, the steel structure module a further includes:

[0102] The fourth steel structural member 7 is arranged side by side with the second steel structural member 3;

[0103] The third steel structural member 4 and the fourth steel structural member 7 are connected by another end plate;

[0104] The connecting plate 5 is also used to connect the end plate 1 of the third steel structural member 4 and the fourth steel structural member 7;

[0105] The steel structure module a also includes: a plurality of second connecting plates 8, each of the second connecting plates 8 being distributed sequentially along the length direction of the second steel structure member 3 and connecting the side of the second steel structure member 3 and the fourth steel structure member 7.

[0106] The ends of the third steel structural member 4 and the fourth steel structural member 7 are connected by an additional end plate 1, ensuring the structural continuity of these two parallel members at one end of the module. Multiple second connecting plates 8, arranged along the length of the second steel structural member 3, connect the sides of the second steel structural member 3 and the fourth steel structural member 7. These second connecting plates 8 provide lateral stiffness along the length direction, enhancing the stability of the structural unit composed of the third steel structural member 4 and the fourth steel structural member 7. This design, by adding parallel members and corresponding connectors, achieves lateral expansion of the module, solves the width limitation, and ensures the integrity and stability of the expanded structure, facilitating modular disassembly and reuse.

[0107] In some embodiments, the first steel structural member 2, the third steel structural member 4, the second steel structural member 3, and the fourth steel structural member 7 form an integral structure through the connecting plate 5 located between the end plates 1 of their respective end plates 1.

[0108] The above configuration forms an integral modular structure consisting of four parallel steel structural members (first steel structural member 2, second steel structural member 3, third steel structural member 4, and fourth steel structural member 7) connected by end plates 1, connecting plates 5, and lacing plates (first lacing plate 6 and second lacing plate 8). The individual steel structural members are fixed together, restricting their relative displacement and rotation. This allows the originally independent steel structural members to be combined into a whole that can jointly bear and transmit loads as a unit, solving the problem that simply connecting the components may not ensure that the entire module can work stably and reliably as a whole structure.

[0109] It is worth mentioning that, in this embodiment, the first steel structural member 2, the second steel structural member 3, the third steel structural member 4, and the fourth steel structural member 7 are connected into a whole by connecting plate 5 and connecting plates (first connecting plate 6 and second connecting plate 8). Specifically, the first steel structural member 2 and the third steel structural member 4 are arranged side-by-side in their width direction and connected by the first connecting plate 6, thereby extending the whole in the width direction; the third steel structural member 4 and the fourth steel structural member 7 are arranged side-by-side in their width direction and connected by the second connecting plate 8, thereby extending the whole in the width direction; the two wholes are connected together by connecting plate 5 and extend in the length direction, forming a three-dimensional combined structure. In this way, multiple steel structural members can be combined to form a three-dimensional combined structure with greater length and width. While meeting performance requirements, this structure can meet the needs of engineering projects and improve the adaptability of steel structural members. Moreover, steel structural members can be used individually or in combination, providing greater possibilities for the application of steel structural members and making engineering planning and design more flexible.

[0110] In some embodiments, the first steel structural member 2 and the third steel structural member 3 each have an upper side plate and a lower side plate arranged in parallel, and a central connecting plate connecting the upper side plate and the lower side plate;

[0111] The central connecting plates of the third steel structural member 3 and the first steel structural member 2 are arranged opposite to each other and parallel to each other.

[0112] Since the central connecting plates of the third steel structural member 3 and the first steel structural member 2 are arranged opposite to each other and parallel to each other, and the upper side plate of the first steel structural member 2 is on the same plane as the upper side plate or lower side plate of the third steel structural member 3, the combination of the two can provide a plane for the installation of the first connecting plate 6. Furthermore, in this embodiment, the first steel structural member 2 and the third steel structural member 3 are essentially I-beams; the upper and lower side plates mentioned above refer to the flanges of the I-beams, while the central connecting plate refers to the web of the I-beams.

[0113] It is worth mentioning that, in this embodiment, as Figure 4 As shown, a relatively enclosed space exists between the first steel structural member 2 and the third steel structural member 3, and a gap communicating with this space exists between the upper side plate of the first steel structural member 2 and the upper side plate of the second steel structural member. Some of the screw holes on the end plate are located within this enclosed space; therefore, the screw holes within this enclosed space may lack sufficient working space, making it impossible to install bolts. Therefore, in this embodiment, the positions of the first steel structural member 2 and the third steel structural member 3 can be adjusted to increase the gap between the upper side plate of the first steel structural member 2 and the upper side plate of the second steel structural member, allowing the installation tool to extend through this gap into the space between the first steel structural member 2 and the third steel structural member 3 to install bolts.

[0114] In other embodiments, the location of the screw holes can be designed so that, even without bolts installed in the screw holes within the enclosed space, other screw holes outside the enclosed space, after bolt installation, still provide sufficient connection strength to meet mechanical performance requirements. Therefore, in this case, no special design is needed for the positions of the first steel structural member 2 and the third steel structural member 3. Specifically, as... Figure 8 As shown, the first steel structural member 2 and the third steel structural member 3 can be arranged in a closely spaced configuration, that is, the upper side plate of the first steel structural member 2 and the upper side plate of the second steel structural member are closely spaced, forming a sealed space between the first steel structural member 2 and the third steel structural member 3. This configuration can also effectively prevent foreign objects from entering the sealed space.

[0115] Implementation Method 4

[0116] This embodiment is a further improvement based on the first, second, or third embodiment, and the improvement lies in that, for example... Figure 5 As shown, the first steel structural member 2 is a reusable component, and a marking attachment 9 is provided on the first steel structural member 2. The marking attachment 9 is used to identify the identity of the first steel structural member 2.

[0117] The reused components refer to steel structural members that have been disassembled non-destructively after the initial engineering is completed and have undergone surface treatment and dimensional calibration. The marking attachment 9 refers to an information carrier that is physically bound to the steel structural member and is used to identify the identity of the first steel structural member 2. In some embodiments, the first steel structural member 2 is an I-beam, and the marking attachment 9 can be set on the web of the I-beam. This is because, in various stages such as the use, transportation, installation, and dismantling of the I-beam, the web area of ​​the I-beam is less likely to be impacted and is relatively safe, which can effectively ensure the stability and safety of the marking attachment 9.

[0118] Specifically, the reused steel structural components are disassembled without damage via bolt connections, with the end plates 1 maintaining their complete structural form. Marking attachment 9 is fixed to a non-load-bearing area, such as the middle of the web of an I-beam, during the initial installation of the component. The information carried by marking attachment 9 can be linked to a database through a steel structure information traceability system, recording data such as the specifications, usage records, and inspection reports of the first steel structural component 2 corresponding to marking attachment 9. During inter-project transfers, the construction party can obtain the specifications, usage records, and inspection reports of the steel structural component by scanning the code using a scanning device.

[0119] Because the marking attachment 9, which records information about steel structural components, corresponds one-to-one with each component, the entire lifecycle management of steel structural module A (supply, installation, dismantling, and reuse) can be achieved through the steel structural information traceability system. For example, during the production stage of a steel structural component, marking attachment 9 is used to mark the component, and the production information and other data of that component are bound to marking attachment 9 within the steel structural information traceability system. After the steel structural component is used in a project, its usage records and other data can be synchronously updated to the steel structural information traceability system. After the recycled steel structural component undergoes inspection and repair, the corresponding data can also be synchronously updated to the steel structural information traceability system. Through these settings, traceability of steel structural components is achieved, improving reuse efficiency; combined with the steel structural information traceability system, the usage history of steel structural components is recorded, reducing the risk of repeated use, promoting the recycling of steel structural module A, and reducing resource waste.

[0120] In some embodiments, the marking attachment 9 can be a PVC label (3mm thick) affixed to the flange of the H-beam, with a built-in chip. The chip information can be read by a corresponding reading device, and the information can be queried in the steel structure information traceability system.

[0121] In some preferred embodiments, the marking attachment 9 is a stainless steel sheet with a QR code. The stainless steel sheet can be made of 304 or 316 stainless steel through laser engraving or stamping processes, utilizing the corrosion resistance and mechanical strength of stainless steel to ensure the long-term preservation of the marking in the construction environment. The material's lifespan being the same as the steel structure ensures the marking remains intact throughout the component's entire lifespan, preventing marking failure due to environmental corrosion.

[0122] Specifically, stainless steel sheets are fixed to the surface of the steel structure, for example, through welding to achieve permanent attachment. During the recycling phase, a scanning device automatically scans the QR code to instantly retrieve the component's quality inspection report and compatibility information, thereby determining whether it meets the requirements of the new project. This embodiment, through the combination of physical carriers and digital encoding, ensures that information is not tampered with or lost during transportation, storage, and construction, while supporting fully automated data management throughout the entire process.

[0123] In traditional engineering projects, steel structural components are often identified using spray-painted numbers or hanging tags, which are prone to information loss during transportation, collisions, or outdoor storage. This solution uses stainless steel sheets as marking attachments (9), which are welded to the steel structural components to identify them. This solves the problem of traditional marking methods being easily damaged and faded, leading to the loss of traceability of structural component identification information after long-term service. Furthermore, compared to traditional numbering, QR codes can record more data and support contactless scanning, effectively improving recognition efficiency.

[0124] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this patent to facilitate a better understanding of the invention. However, even without these technical details and various variations and modifications based on the above embodiments, the technical solutions claimed in the claims of this patent can be substantially achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of this patent.
