Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of public bench seat technology, specifically to prefabricated bench seats and prefabricated bench seat assembly methods. Background Technology

[0002] Public benches are an indispensable infrastructure in outdoor public spaces, widely used in various open activity areas. Currently, most public benches on the market adopt traditional structural designs and construction methods, mainly divided into two types: one-piece cast-in-place and simple assembly. One-piece cast-in-place benches require on-site concrete pouring, while simple assembly benches use ordinary materials for easy assembly. Both types are widely used in various outdoor public scenarios.

[0003] However, the inventors discovered that when the aforementioned traditional public benches are used in outdoor public spaces, the following technical problems often arise: Traditional one-piece cast-in-place seating has a long construction cycle and a large amount of on-site work. Its fixed structure makes it impossible to flexibly adjust its position according to the layout of public spaces. Later maintenance and replacement require complete dismantling, resulting in high maintenance costs and poor flexibility. Simple splicing seating has unreasonable connection methods for its components and lacks a reliable fixing structure. When exposed to the outdoor environment for a long time, it is susceptible to the effects of wind and rain erosion, temperature changes, and frequent use by people, resulting in problems such as loosening, falling off, and damage. Its structural stability and durability are insufficient, and it cannot meet the public rest needs in the long term. Summary of the Invention

[0004] The summary portion of this disclosure is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description portion. This summary portion is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] Some embodiments of this disclosure propose prefabricated bench seats and prefabricated bench seat assembly methods to solve the technical problems mentioned in the background section above.

[0006] In a first aspect, some embodiments of this disclosure provide a prefabricated strip seat, which includes a prefabricated concrete structure, bamboo strips, and supporting steel components. An embedded part is pre-embedded inside the prefabricated concrete structure. One end of the prefabricated concrete structure and one end of the bamboo strips are fixedly connected via the embedded part and a first steel connector. The other end of the bamboo strips is connected to the supporting steel components via a second steel connector. The first and second steel connectors are fastened with through bolts, and the first steel connector is welded to the embedded part. One end of the supporting steel components is welded to the second steel connector. A reserved hole is provided on the bamboo strip to mate with the through bolt, and the diameter of the reserved hole is adapted to the diameter of the through bolt.

[0007] Optionally, the finish of the above-mentioned prefabricated concrete structure is made by bonding terrazzo with cement mortar and then grinding it into shape.

[0008] Optionally, the above-mentioned prefabricated concrete structure includes a precast concrete matrix, a reinforcing cage is provided inside the precast concrete matrix, the embedded part is tied and fixed to the reinforcing cage as a whole, and the exposed end of the embedded part is welded to the corresponding steel connector.

[0009] Optionally, the other end of the aforementioned supporting steel member is fixedly connected to the ground-mounted embedded part by expansion bolts, and the aforementioned bamboo and wood strips are connected to the aforementioned second steel connector and the aforementioned supporting steel member by through bolts. Optionally, a bamboo disc is provided at the end of the bamboo strip, and the bamboo disc is interference-fitted with the end of the bamboo strip.

[0010] Secondly, some embodiments of this disclosure provide an assembly method for a prefabricated strip seat, applicable to the prefabricated strip seat described in the first aspect, comprising: ground installation of the prefabricated concrete structure; welding and fixing a first steel connector to the prefabricated concrete structure via embedded parts; fixing a supporting steel member to the ground using expansion bolts; welding and fixing the supporting steel member to a second steel connector; and fastening bamboo strips to the first and second steel connectors.

[0011] Optionally, before the above-mentioned prefabricated concrete structure is installed on the ground, the method further includes: applying terrazzo to the surface of the prefabricated concrete structure using cement mortar; and grinding the terrazzo applied to the surface of the prefabricated concrete structure.

[0012] Optionally, the above-mentioned fastening and fixing of the bamboo strips to the first steel connector and the second steel connector includes: pre-arranging and installing the bamboo strips; in response to confirming that the pre-arrangement is qualified, fastening and fixing the bamboo strips to the first steel connector and the second steel connector by passing through the pre-drilled holes on the bamboo strips with through bolts.

[0013] Optionally, the above method also includes: applying anti-corrosion treatment to each welding point.

[0014] Optionally, the above method further includes: inserting bamboo or wooden discs into the ends of the bamboo or wooden strips.

[0015] Optionally, the aforementioned prefabricated strip seat further includes a detection device and a processor. The detection device includes various pressure sensors, which are respectively installed above and below the connection between the bamboo strip and the first steel connector. The method further includes: acquiring an initial pressure information set detected by the pressure sensors under no-load conditions using the processor, wherein each initial pressure information in the initial pressure information set corresponds to a pressure sensor identifier, and different initial pressure information corresponds to different pressure sensor identifiers; determining whether each initial pressure information in the initial pressure information set is within the initial qualified pressure range; and responding to the determination of the initial pressure information set... Each initial pressure information is within the initial qualified pressure range. The processor acquires the load-bearing pressure information set detected by each pressure sensor under the load, wherein each load-bearing pressure information in the load-bearing pressure information set corresponds to a pressure sensor identifier, and different load-bearing pressure information corresponds to different pressure sensor identifiers. The processor determines the absolute value of the upper and lower difference between the load-bearing pressure information of the corresponding upper pressure sensor and the load-bearing pressure information of the corresponding lower pressure sensor in the load-bearing pressure information set. The processor determines whether the absolute value of the upper and lower difference is less than a preset upper and lower difference threshold. In response to determining that the absolute value of the upper and lower difference is less than the preset upper and lower difference threshold, the processor determines that the assembled strip seat is qualified for assembly.

[0016] The above-described embodiments of this disclosure have the following beneficial effects: the prefabricated strip seats through some embodiments of this disclosure can improve structural stability and durability while improving assembly efficiency and flexibility. Specifically, the reasons for poor structural stability and durability, as well as poor assembly efficiency and flexibility, are as follows: traditional one-piece cast-in-place seats have long construction cycles, large on-site workload, and fixed structures that cannot be flexibly adjusted according to the layout of public spaces. Later maintenance and replacement require complete dismantling, resulting in high maintenance costs and poor flexibility; simple splicing seats have unreasonable connection methods for each component, lack reliable fixing structures, and are easily affected by factors such as wind and rain erosion, temperature changes, and frequent use by people when exposed to the outdoor environment for a long time, resulting in problems such as loosening, falling off, and damage. The structural stability and durability are insufficient, and they cannot meet the public rest needs for a long time. Based on this, some embodiments of the prefabricated strip seat disclosed herein include a prefabricated concrete structure, bamboo and wood strips, and supporting steel components; the prefabricated concrete structure has embedded parts inside, and one end of the prefabricated concrete structure and the bamboo and wood strips are fixedly connected by the embedded parts and a first steel connector, while the other end of the bamboo and wood strips is connected to the supporting steel components by a second steel connector; the first steel connector and the second steel connector are fastened by through bolts, and the first steel connector is welded to the embedded parts, and one end of the supporting steel components is welded to the second steel connector; the bamboo and wood strips have reserved holes that mate with the through bolts, and the diameter of the reserved holes is adapted to the diameter of the through bolts. Therefore, through the prefabricated modular component design and scientific connection method of the prefabricated strip seats, precise splicing and reliable fixing of each component are achieved, ensuring high structural stability and durability of the seats. This replaces the traditional one-piece casting and simple splicing construction methods, simplifying the installation process, reducing on-site work, and improving assembly efficiency. Simultaneously, the prefabricated structure can be flexibly adjusted in position according to the on-site work layout, and subsequent maintenance and replacement can be performed by disassembling the corresponding components individually without the need for overall dismantling, significantly improving the layout and maintenance flexibility of the seats. Thus, the prefabricated strip seats of some embodiments of this disclosure can improve structural stability and durability while increasing assembly efficiency and flexibility.

The bamboo and wood strips 2 include pre-drilled holes 21 and 22. The prefabricated concrete structure 1 includes embedded parts 11.

[0028] Figure 4 This is a side sectional view of a prefabricated strip seat according to some embodiments of this disclosure. Figure 4 It includes bamboo and wood strips 2, a second steel connector 4, supporting steel components 5, and a ground surface 6. Bamboo and wood strips 2 include through bolts 23 and bamboo and wood round caps 24. Supporting steel components 5 include rear-mounted embedded parts 51 and expansion bolts 52.

[0029] Figure 5 This is a structural schematic diagram of the steel connector in a prefabricated strip seat according to some embodiments of this disclosure. Figure 5 It includes a first steel connector 4. The first steel connector 4 includes a pre-drilled hole 41.

[0030] In some embodiments, the prefabricated strip seat may include a prefabricated concrete structure 1, bamboo strips 2, and supporting steel members 5. The prefabricated concrete structure 1 has embedded parts 11 pre-embedded inside. One end of the prefabricated concrete structure 1 and the bamboo strip 2 are fixedly connected via the embedded parts 11 and a first steel connector 3. The other end of the bamboo strip 2 is connected to the supporting steel member 5 via a second steel connector 4. The prefabricated concrete structure 1 can serve as the main load-bearing structure of the seat, providing stable support. The bamboo strip 2 can serve as the seat's surface component, providing a comfortable resting contact surface. The supporting steel member 5 can serve as the support structure for the other end of the bamboo strip 2, assisting in fixing the bamboo strip 2 and enhancing the overall stability of the seat. The embedded parts 11 can be metal components pre-embedded inside the prefabricated concrete structure 1, used to connect to the first steel connector 3. The first steel connector 3 can be a metal connector used to connect the prefabricated concrete structure 1 to one end of the bamboo strip 2. The aforementioned second steel connector 4 can be a metal connector used to connect the other end of the bamboo strip 2 to the supporting steel component 5.

[0031] In some embodiments, the first steel connector 3 and the second steel connector 4 are fastened together by through bolts 23, and the first steel connector 3 is welded to the embedded part 11, while one end of the supporting steel member 5 is welded to the second steel connector 4. The through bolts 23 can be fasteners that penetrate the first steel connector 3, the bamboo strip 2, or the second steel connector 4, used to fasten the components together. The welding fixation can be achieved by high-temperature fusion welding, connecting the first steel connector 3 to the embedded part 11 and the supporting steel member 5 to the second steel connector 4 to ensure a strong connection.

[0032] In some embodiments, the bamboo strip 2 is provided with pre-drilled holes (e.g., pre-drilled hole 21 that mates with a pre-drilled hole in the first steel connector 3 and pre-drilled hole 41 that mates with a pre-drilled hole in the second steel connector 4), and the diameter of the pre-drilled holes is adapted to the diameter of the through bolt 23. These pre-drilled holes can be holes pre-drilled during the processing of the bamboo strip 2, for the through bolt 23 to pass through. The adaptation of the hole diameter to the diameter of the through bolt 23 can be achieved by the inner diameter of the pre-drilled hole being slightly larger than the outer diameter of the through bolt 23, ensuring that the through bolt 23 can pass through smoothly and remains secure after tightening.

[0033] Optionally, the surface finish of the prefabricated concrete structure 1 is achieved by bonding terrazzo with cement mortar and then polishing it. The cement mortar can be a bonding material made by mixing cement, sand, and water in a predetermined ratio, used to bond the terrazzo to the surface of the prefabricated concrete structure 1. The terrazzo can be a finishing material made by mixing cement as a binder and marble or granite chips as aggregate, followed by molding, curing, and polishing. The polishing process involves using polishing equipment to polish the bonded terrazzo surface to make it smooth and even, improving its aesthetics and wear resistance.

[0034] Optionally, the prefabricated concrete structure 1 includes a precast concrete matrix, within which a reinforcing cage is installed. The embedded part 11 is bound and fixed integrally with the reinforcing cage, and the exposed end of the embedded part 11 is welded to a corresponding steel connector (first steel connector 3). The precast concrete matrix can be the core of the prefabricated concrete structure 1, formed using a factory prefabrication method. The reinforcing cage can be a mesh structure made of bound reinforcing bars, installed inside the precast concrete matrix to enhance the strength and crack resistance of the prefabricated concrete structure 1. The binding and fixing can be achieved by using binding wire to tightly connect the embedded part 11 to the reinforcing cage, ensuring that the embedded part 11 does not shift position during concrete pouring. The exposed end of the embedded part 11 can be the portion extending beyond the surface of the precast concrete matrix, used for welding connection with the first steel connector 3.

[0035] Optionally, the other end of the aforementioned supporting steel member 5 is fixedly connected to the post-embedded part 51 of the ground 6 via expansion bolts 52, and the aforementioned bamboo strip 2 is fastened to the aforementioned second steel connector 4 and the aforementioned supporting steel member 5 via through bolts 23. The aforementioned expansion bolts 52 can be fasteners that utilize the frictional force generated by expansion to fix the supporting steel member 5 to the ground 6. The aforementioned post-embedded part 51 of the ground 6 can be a metal component pre-embedded inside the ground 6, used to cooperate with the expansion bolts 52 to fix the supporting steel member 5. The aforementioned fastening connection can be achieved by using through bolts 23 to tightly fix the bamboo strip 2 to the second steel connector 4 and the supporting steel member 5, ensuring that the bamboo strip 2 is firmly installed and without loosening.

[0036] Optionally, a bamboo or wood disc 24 is provided at the end of the bamboo or wood strip 2, and the bamboo or wood disc 24 is interference-fitted with the end of the bamboo or wood strip 2. The bamboo or wood disc 24 can be a circular component made of bamboo or wood, and is provided at the end of the bamboo or wood strip 2. The interference fit can be such that the outer diameter of the bamboo or wood disc 24 is slightly larger than the inner diameter of the end of the bamboo or wood strip 2, and the bamboo or wood disc 24 is embedded into the end of the bamboo or wood strip 2 by compression to achieve a tight connection, thereby sealing the end of the bamboo or wood strip 2 and improving its aesthetics.

[0037] The above-described embodiments of this disclosure have the following beneficial effects: the prefabricated strip seats through some embodiments of this disclosure can improve structural stability and durability while improving assembly efficiency and flexibility. Specifically, the reasons for poor structural stability and durability, as well as poor assembly efficiency and flexibility, are as follows: traditional one-piece cast-in-place seats have long construction cycles, large on-site workload, and fixed structures that cannot be flexibly adjusted according to the layout of public spaces. Later maintenance and replacement require complete dismantling, resulting in high maintenance costs and poor flexibility; simple splicing seats have unreasonable connection methods for each component, lack reliable fixing structures, and are easily affected by factors such as wind and rain erosion, temperature changes, and frequent use by people when exposed to the outdoor environment for a long time, resulting in problems such as loosening, falling off, and damage. The structural stability and durability are insufficient, and they cannot meet the public rest needs for a long time. Based on this, some embodiments of the prefabricated strip seat disclosed herein include a prefabricated concrete structure, bamboo and wood strips, and supporting steel components; the prefabricated concrete structure has embedded parts inside, and one end of the prefabricated concrete structure and the bamboo and wood strips are fixedly connected by the embedded parts and a first steel connector, while the other end of the bamboo and wood strips is connected to the supporting steel components by a second steel connector; the first steel connector and the second steel connector are fastened by through bolts, and the first steel connector is welded to the embedded parts, and one end of the supporting steel components is welded to the second steel connector; the bamboo and wood strips have reserved holes that mate with the through bolts, and the diameter of the reserved holes is adapted to the diameter of the through bolts. Therefore, through the prefabricated modular component design and scientific connection method of the prefabricated strip seats, precise splicing and reliable fixing of each component are achieved, ensuring high structural stability and durability of the seats. This replaces the traditional one-piece casting and simple splicing construction methods, simplifying the installation process, reducing on-site work, and improving assembly efficiency. Simultaneously, the prefabricated structure can be flexibly adjusted in position according to the on-site work layout, and subsequent maintenance and replacement can be performed by disassembling the corresponding components individually without the need for overall dismantling, significantly improving the layout and maintenance flexibility of the seats. Thus, the prefabricated strip seats of some embodiments of this disclosure can improve structural stability and durability while increasing assembly efficiency and flexibility.

[0038] Figure 6 This is a flowchart illustrating an assembly method for a prefabricated bench seat according to some embodiments of the present disclosure. A flowchart 600 is shown for some embodiments of the assembly method for a prefabricated bench seat according to the present disclosure.

[0039] The assembly method of this modular bench seat includes the following steps: Step 601: Install the prefabricated concrete structure on the ground.

[0040] In some embodiments, an execution entity (e.g., a robot) can perform ground installation of the prefabricated concrete structure. The execution entity installs the prefabricated concrete structure to a preset position on the ground 6. This lays the foundation for the subsequent connection and fixing of various components, ensuring the stability and standardization of the overall seat installation.

[0041] Furthermore, prior to installation, the composite components can be further designed in detail, clarifying design parameters: primarily defining the prefabricated concrete shape, steel conversion parts specifications, and bamboo / wooden strip specifications. This involves the prefabrication and transportation of the prefabricated concrete (including embedded parts), steel conversion parts (with openings), and bamboo / wooden strips (with openings). The installation of the prefabricated concrete structure includes: prefabricated component design, concrete type design, factory prefabrication and splicing of formwork, formwork support erection, steel reinforcement cage fabrication in the steel reinforcement factory, binding and fixing of embedded parts, concrete pouring and curing, and on-site transportation and storage of concrete components.

[0042] Step 602: The first steel connector is welded and fixed to the prefabricated concrete structure through embedded parts.

[0043] In some embodiments, the aforementioned executing entity can weld and fix the first steel connector to the aforementioned prefabricated concrete structure using embedded parts. In practice, the aforementioned executing entity can connect the first steel connector to the embedded parts inside the prefabricated concrete structure as a whole by welding. The welding fixation uses high-temperature fusion to tightly combine the two metal components (the first steel connector and the embedded parts), ensuring a firm connection and providing a stable connection foundation for the subsequent installation of bamboo and wood strips, preventing loosening during later use.

[0044] Step 603: Secure the supporting steel component to the ground using expansion bolts.

[0045] In some embodiments, the aforementioned actuator can fix the supporting steel component to the ground using expansion bolts. In practice, the actuator can drive the expansion bolts into the ground, utilizing the friction between the expanded bolts and the ground to firmly fix one end of the supporting steel component to the ground. This ensures that the supporting steel component can provide stable support for the bamboo strips, preventing the seat from shifting or wobbling due to force, and ensuring the overall stability of the seat installation.

[0046] Step 604: Weld and fix the supporting steel component to the second steel connector.

[0047] In some embodiments, the aforementioned execution entity may weld and fix the aforementioned supporting steel member to the second steel connector.

[0048] Step 605: Secure the bamboo strips to the first and second steel connectors.

[0049] In some embodiments, the aforementioned executing entity can fasten and fix the bamboo strip to the first steel connector and the second steel connector. The aforementioned executing entity can fasten and fix both ends of the bamboo strip to the first steel connector and the second steel connector respectively, so that the bamboo strip can be stably installed between the two steel connectors to form the resting surface of the seat.

[0050] Optionally, before the above-mentioned prefabricated concrete structure is installed on the ground, the method further includes: The first step is to use cement mortar to adhere terrazzo to the surface of the prefabricated concrete structure.

[0051] The second step is to grind the terrazzo that is pasted on the surface of the prefabricated concrete structure.

[0052] Optionally, the above-mentioned fastening and fixing of the bamboo strips to the first steel connector and the second steel connector includes: The first step is to pre-arrange and install the bamboo and wood strips. In practice, the aforementioned implementer can initially arrange the bamboo and wood strips between the first and second steel connectors, adjusting the position and spacing of the bamboo and wood strips to ensure that the bamboo and wood strips are evenly and flatly arranged, conforming to the design dimensions and installation standards of the seat. This prepares for subsequent fastening and fixation, avoiding unevenness and uneven stress on the seat surface after fastening due to arrangement deviations.

[0053] The second step, in response to confirming the pre-arrangement is qualified, involves using through bolts to secure the bamboo strips to the first and second steel connectors. In practice, the executing entity can either pass the through bolts through the first pre-drilled hole in the bamboo strip, through the first steel connector, and tighten the bolts to firmly secure the bamboo strip to the first steel connector. Alternatively, the executing entity can pass the through bolts through the second pre-drilled hole in the bamboo strip, through the second steel connector, and tighten the bolts to firmly secure the bamboo strip to the first steel connector, ensuring the bamboo strips are firmly installed without loosening, while also guaranteeing the flatness of the bamboo strip installation.

[0054] Optionally, the above method further includes: applying anti-corrosion treatment to each welding point. This anti-corrosion treatment can be applying rust-preventive paint or hot-dip galvanizing.

[0055] Optionally, the above method further includes: inserting a bamboo disc into the end of the bamboo strip. In practice, the aforementioned implementing entity can embed the bamboo disc into the end of the bamboo strip by compression (interference fit). The interference fit means that the outer diameter of the bamboo disc is slightly larger than the inner diameter of the end of the bamboo strip. After compression, a tight connection is achieved. Its function is to seal the end of the bamboo strip, prevent the inside of the bamboo strip from getting damp or damaged, and at the same time improve the neatness and aesthetics of the seat.

[0056] In the process of using the above-mentioned prefabricated structural technology to solve the technical problems of unstable structure, low assembly efficiency and poor flexibility of traditional public bench seats, the following technical problem often arises: After the components of the prefabricated bench seat are assembled, it is impossible to accurately determine whether the installation is qualified. In particular, the connection between bamboo and wood strips and steel connectors, and the load-bearing stability of the prefabricated concrete structure, lack scientific and accurate testing methods. Relying solely on manual visual observation or simple manual shaking cannot detect potential problems such as loose installation and uneven stress. This leads to safety hazards after the seat is installed, and long-term use may result in component detachment, structural deformation, etc., affecting the structural stability and service life of the seat. In fact, improper installation may even cause personal injury to users.

[0057] Regarding the second technical problem mentioned above, the conventional solution is generally to manually check the tightness of the connections of each component, shaking bamboo and wooden strips and prefabricated concrete structures to determine if they are loose, and observing whether there are obvious signs of misalignment or loosening at each weld point and bolt connection. However, the above conventional solution still has the following problems: manual judgment relies on the operator's experience, which is highly subjective and cannot accurately identify potential hazards such as slight loosening or uneven stress; it lacks quantitative testing standards, making it impossible to accurately assess the stress state after installation, resulting in large errors in the judgment results; and it cannot achieve comprehensive testing of each connection, which is prone to omissions, and still cannot completely avoid the safety hazards caused by substandard installation, resulting in poor testing reliability.

[0058] Considering the problems with the conventional solutions mentioned above, and addressing the second technical issue—the inability to accurately determine the installation quality of prefabricated bench seats after assembly—especially regarding the connections between bamboo / wood strips and steel connectors, and the load-bearing stability of the prefabricated concrete structure, the lack of scientific and precise testing methods, relying solely on visual inspection or simple manual shaking, fails to detect potential issues such as loose installations and uneven stress. This leads to safety hazards after installation, and long-term use may result in component detachment and structural deformation, affecting the structural stability and lifespan of the seat, and potentially causing personal injury to users due to improper installation. Based on the current technological situation, the following solution can be adopted: Optionally, the aforementioned prefabricated strip seat further includes a detection device and a processor. The detection device includes various pressure sensors, which are respectively installed above and below the connection point between the bamboo / wooden strip and the first steel connector. For example, four pressure sensors can be installed above the connection point between the bamboo / wooden strip and the first steel connector. Similarly, four pressure sensors can be installed below the connection point between the bamboo / wooden strip and the first steel connector.

[0059] The above methods also include: The first step is to obtain the initial pressure information set detected by each pressure sensor when no heavy object is loaded through the processor. Each initial pressure information in the initial pressure information set corresponds to a pressure sensor identifier, and different initial pressure information corresponds to different pressure sensor identifiers.

[0060] The second step is to determine whether each initial pressure information in the aforementioned initial pressure information set is within the initial acceptable pressure range. In practice, this involves determining whether the initial pressure information detected by each upper pressure sensor is within the initial acceptable upper pressure range, and whether the initial pressure information detected by each lower pressure sensor is within the initial acceptable lower pressure range.

[0061] The third step is to determine that each initial pressure information in the above initial pressure information set is within the initial qualified pressure range, and to obtain the load-bearing pressure information set detected by each pressure sensor under the load of the heavy object through the processor. Each load-bearing pressure information in the above load-bearing pressure information set corresponds to a pressure sensor identifier, and different load-bearing pressure information corresponds to different pressure sensor identifiers.

[0062] The fourth step is to determine the absolute value of the difference between the upper and lower load-bearing pressure information of the corresponding upper pressure sensor and the lower load-bearing pressure information in the aforementioned load-bearing pressure information set. In practice, the absolute value of the difference between the average value of the load-bearing pressure information of each corresponding upper pressure sensor and the average value of the load-bearing pressure information of each corresponding lower pressure sensor can be determined.

[0063] The fifth step is to determine whether the absolute value of the above-mentioned upper and lower differences is less than a preset upper and lower difference threshold. The preset upper and lower difference threshold can be a pre-set value indicating that the absolute value of the above-mentioned upper and lower differences is less than the threshold value for the assembled strip seat to be considered properly assembled.

[0064] Step 6: In response to determining that the absolute value of the above-mentioned upper and lower differences is less than the above-mentioned preset upper and lower difference threshold, the assembly of the prefabricated strip seat is deemed qualified.

[0065] The aforementioned content regarding the detection of the assembly qualification of prefabricated bench seats using pressure sensors is an inventive point of this disclosure, solving technical problem two: "After the components of prefabricated bench seats are assembled, it is impossible to accurately determine whether the installation is qualified, especially at the connection between bamboo and wooden strips and steel connectors, and the load-bearing stability of prefabricated concrete structures. There is a lack of scientific and precise testing methods; relying solely on visual observation or simple manual shaking cannot detect potential problems such as loose installation or uneven stress, leading to safety hazards after installation. Long-term use can easily result in component detachment and structural deformation, affecting the structural stability and service life of the seat, and may even cause personal injury to users due to improper installation." The reasons for inaccurate installation detection and safety hazards are as follows: After the components of prefabricated bench seats are assembled, there is a lack of scientific and precise testing methods. Relying solely on visual observation or simple manual shaking cannot detect potential problems such as loose installation or uneven stress. Furthermore, manual judgment is highly subjective and lacks quantitative standards, easily leading to missed detections and misjudgments. If the above factors are addressed, accurate detection of the installation qualification of prefabricated bench seats can be achieved, avoiding installation safety hazards and ensuring the structural stability and service life of the seats. To achieve this effect, the prefabricated bench seat disclosed herein provides an installation detection scheme based on pressure sensors. By installing pressure sensors above and below the connection between the bamboo / wooden strips and the steel connectors, and using a processor to collect pressure information under both unloaded and loaded conditions, the system accurately determines whether the installation is qualified by judging whether the initial pressure meets the standard and whether the pressure difference between the upper and lower parts under load meets the threshold. This achieves quantitative detection of the installation status of prefabricated bench seats, avoiding the subjectivity and error of manual judgment, accurately identifying potential installation hazards, ensuring qualified installation, and further guaranteeing the structural stability, service life, and safety of the seats.
