Description

Technical Field

[0001] This invention relates to the field of steel structure assembly technology, specifically to a modular steel structure. Background Technology

[0002] Modular steel structure is a type of building structure that consists of multiple standardized modules. These modules are prefabricated in a factory and then transported to the site for rapid assembly. The modules are connected by specific methods, such as screw connections and plug-in connections, to form a stable overall structure. It is suitable for various building types, such as temporary buildings and industrial plants.

[0003] Chinese patent CN115059176A discloses a modular steel structure connection node, including a connection module and a positioning structure. Two connection modules are provided and installed at the upper and lower ends of the positioning structure, respectively. Each connection module includes four connection structures and a connection block. The cross-sectional shape of the connection block is square. The four connection structures are respectively installed on the four vertical surfaces of the connection block. Adjacent connection structures are in contact and are threaded together with a No. 2 screw. Two vertically opposite connection structures are threaded together with a No. 1 screw. The No. 1 screw penetrates the positioning structure. The end face of the connection block facing the positioning structure is on the same plane as the end face of the connection structure facing the positioning structure. The connection structure includes a longitudinal connecting pipe and a transverse connecting pipe.

[0004] However, the equipment and existing technology mentioned in the above-mentioned reference documents still have the following defects in actual use: 1. Compared with the modular steel structure involved in the reference documents, it mainly includes two symmetrically arranged connecting modules, positioning structure, No. 1 screw and No. 2 screw. The connecting module is composed of four connecting structures and connecting blocks. Each connecting structure contains one longitudinal connecting pipe and two transverse connecting pipes. Therefore, there are four longitudinal connecting pipes and eight transverse connecting pipes in the same connecting module. The four longitudinal connecting pipes form a column structure.

[0005] First, during the assembly process, there are multiple operations that require the use of screws for connection. The four connecting structures in the same connecting module must first be connected to the connecting block, and then connected together with screw #2. Finally, the upper and lower connecting modules need to be connected together with the positioning structure and screw #2. This means that after the assembly is completed, the workers need to perform screw connection and installation work multiple times. For modular steel structure splicing and installation, there will be multiple such connection nodes, so the number of screw connections will be considerable, greatly increasing the labor intensity and working time of the workers.

[0006] Secondly, due to the structural characteristics of steel structures, the location of screw connections is not always easy to operate. In some complex structural parts, workers need to tighten screws in a narrow space. This not only requires special tools and skills, but also causes inconvenience due to the limited operating space, and may even result in screws not being tightened properly, affecting the stability of the connection.

[0007] Finally, from the perspective of the entire installation process, due to the large number of design components and the relatively fixed connection methods and order of each component, for example, the four connection structures in the same connection module must be connected to the connection block first before other connection operations can be performed. This strict installation order limits the flexibility of the installation process. Once a problem occurs in a certain link, subsequent operations cannot be carried out smoothly and need to be readjusted or reworked, which will affect the overall installation progress.

[0008] 2. Compared to existing technologies, steel has the characteristic of thermal expansion and contraction. Under different temperature environments, the dimensions of steel structural components will change. When the temperature changes, the components will produce gaps due to expansion or contraction. For example, steel structures installed in the high temperature environment of summer will easily cause gaps to appear at the joints when the temperature drops in winter due to the contraction of the components. Furthermore, during the long-term use of steel structures, they will be subjected to various loads, such as self-weight, wind load, and seismic action. These loads will cause the steel structure to deform. If the deformation exceeds a certain limit, it will cause the connection between components to loosen, resulting in gaps. For example, in areas with large wind loads, steel structure buildings subjected to wind force for a long time may gradually deform, causing the gaps at the joints to gradually increase.

[0009] The presence of gaps can compromise the airtightness of steel structures, allowing external moisture, dust, corrosive gases, and other contaminants to easily enter the interior. This not only affects the appearance of the steel structure but also leads to corrosion and damage to internal components, reducing the service life of the steel structure.

[0010] Therefore, in view of this, the present invention proposes a modular steel structure to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0011] To address the aforementioned technical problems, this invention provides a modular steel structure to solve the technical problems mentioned in the background section.

[0012] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a modular steel structure, including a steel structure body, an assembly plate fixedly connected to the side wall of the steel structure body, assembly holes uniformly opened through the surface of the assembly plate, and an auxiliary installation mechanism provided on the outside of the steel structure body, the auxiliary installation mechanism being used to realize the rapid and accurate assembly between the steel structure bodies.

[0013] Furthermore, the auxiliary installation mechanism includes an external gear ring disposed on the outside of the main steel structure, an internal gear ring fixedly connected inside the external gear ring, a limit plate uniformly rotatably connected to the side wall of the external gear ring, a driven gear shaft installed on the side wall of each limit plate, and mounting screws installed on the outside of each driven gear shaft.

[0014] Furthermore, the mounting screws correspond to the mounting holes on the surface of the mounting plate, and each mounting screw has an adsorption ring installed on its outer wall. The adsorption rings are rotatably connected to the outer wall of the outer toothed ring.

[0015] Furthermore, the driven gear shaft as a whole includes gears and a main shaft. The gears in the driven gear shaft are all engaged with the internal gear ring, and the main shaft in the driven gear shaft is rotatably connected to the limiting plate.

[0016] Furthermore, the assembly screw is made entirely of ferromagnetic metal, and the adsorption ring is made entirely of magnetic material.

[0017] Furthermore, both the outer toothed ring and the inner toothed ring are designed to be telescopic, and each has an elastic cable installed inside. In their initial state, both the outer toothed ring and the inner toothed ring are regular circular shapes.

[0018] Furthermore, the steel structure body is provided with a double-layer temperature control mechanism inside. The double-layer temperature control mechanism is used to specifically control the internal temperature of the steel structure body. The double-layer temperature control mechanism includes a wiring assembly installed inside the steel structure body, and a support member is installed on the outer wall of the wiring assembly.

[0019] Furthermore, the wiring assembly is composed of a solid column and a cylindrical shell, with a perforated groove between the solid column and the cylindrical shell. The wiring assembly is used to lay out the wiring inside the main steel structure.

[0020] Furthermore, the support component is composed of a buffer rod and a support pad, with the buffer rod made of an elastic material and the support pad made of a metal material.

[0021] Furthermore, a heat-conducting ring is fixedly connected to the outer wall of the support member, an inner frame is fixedly connected to the outside of the heat-conducting ring, a cylindrical chamber is uniformly connected to the outside of the inner frame, an outer frame is installed on the outer wall of the cylindrical chamber, and a sealing ring is installed on the outside of the outer frame.

[0022] Furthermore, the heat-conducting ring is entirely made of boron nitride ceramic material, and the sealing ring is entirely made of rubber material.

[0023] Furthermore, both the inner and outer frames contain heat-sensitive materials, and the outer wall of the inner frame is uniformly perforated with through slots, which are located between every two cylindrical compartments.

[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) The device uses the synchronous rotation mechanism of the external gear and the internal gear ring. Under the premise of limiting the assembly screws, the internal gear ring can drive multiple assembly screws to rotate at one time. In this way, the number of assembly screw connection operations is greatly reduced, and the assembly efficiency is significantly improved. Correspondingly, the installation method adopted by the device is also convenient for disassembly and assembly in the later stage. In the maintenance and modification of steel structures, it is often necessary to disassemble and replace some structures. The device only needs to be synchronized with the above-mentioned installation operation to realize the synchronous disassembly of multiple assembly screws. When reassembling, it can also quickly complete the connection, thereby greatly reducing the time cost of maintenance and modification and improving work efficiency.

[0025] Compared to existing technologies, large modular steel structure projects in practice require individual screw tightening. However, by using this device, the number of operations can be reduced by several times, greatly shortening the assembly cycle.

[0026] Furthermore, this device achieves self-positioning and self-calibration of the assembly screws through the cooperation of the limiting plate and the driven gear shaft. It eliminates the need for tedious manual position adjustments, ensuring accurate alignment of the assembly screws at each position and enabling rapid connection. This effectively avoids connection problems caused by human error and improves the accuracy and reliability of the connection.

[0027] Compared to existing technologies, this device, through its design of using an internal gear ring to rotate multiple assembly screws at once, reduces the number of operations required by workers in confined spaces, avoids operational inconveniences caused by space limitations, and can smoothly complete screw connection operations even in complex structural parts, optimizing the utilization of operating space and improving the overall maintenance and modification effect.

[0028] Most importantly, by designing the outer and inner toothed rings to be telescopic, this device eliminates the need for operators to hold the auxiliary installation mechanism continuously during installation. In actual use, the outer toothed ring is stretched to separate and passed through the outside of the steel structure, allowing the auxiliary installation mechanism to be fitted onto the outside of the steel structure. During this process, operators only need to move to align the parts. This method greatly reduces the time and effort required for manual operation, increases the automation level of the installation process, and thus significantly improves the overall installation efficiency. Furthermore, when proceeding to the next step of installing the steel structure, the auxiliary installation structure of this device can easily slide along the outside of the steel structure, enabling rapid positional changes.

[0029] Compared to existing technologies, the sliding position adjustment mechanism of this device is more efficient and convenient. This method enables the installation work to proceed more smoothly, reduces the time wasted due to position adjustments, and helps to complete the splicing and installation of multiple steel structure main bodies in a short time. It is especially suitable for the construction of large-scale steel structure projects.

[0030] This device features magnetic adsorption rings at the corresponding positions of the mounting screws. During actual operation, these rings provide axial force, making the connection between the mounting screws and the mounting holes tighter and preventing loosening. This anti-loosening effect improves the reliability of the connection and ensures the safe operation of the components.

[0031] (2) The double-layer temperature control mechanism introduced in this device can adaptively adjust the sealing according to the temperature difference between the inside and outside of the steel structure. First, when the outside temperature is higher than the inside of the steel structure, the heat-sensitive material inside the outer frame expands due to heat, which causes the sealing ring to expand and cover the gap, effectively preventing the intrusion of external substances, enhancing the sealing performance inside the main body of the steel structure, and ensuring that the steel structure maintains a good sealing state when the outside temperature environment is high.

[0032] Secondly, when the temperature inside the steel structure is higher than the outside temperature, the heat-sensitive material in the inner frame will expand due to heat and move inward, exposing the cylindrical chamber and achieving interconnection between the inner and outer sides. This design allows the interior of the steel structure to exchange heat with the outside, playing a cooling role and avoiding the adverse effects of excessively high internal temperatures on the performance of the steel structure. In some high-temperature environments or when the internal temperature of the steel structure rises due to the heating of internal equipment, this mechanism can automatically activate the cooling function to maintain the stability of the internal temperature of the steel structure, which helps to improve the overall stability and reliability of the steel structure.

[0033] In summary, this device optimizes the internal temperature distribution of the steel structure through the adjustment of the double-layer temperature control mechanism. Under different temperature environments, the mechanism can adaptively adjust according to the temperature difference between the inner and outer sides. This not only prevents structural deformation and performance degradation caused by excessively high temperatures, but also avoids component shrinkage and gap formation caused by excessively low temperatures. This optimized temperature distribution helps reduce stress concentration and deformation problems caused by temperature changes in the steel structure, thereby improving the fatigue resistance and load-bearing capacity of the steel structure.

[0034] In particular, the connection points of steel structures often bear large concentrated stresses. The metal support pads introduced in this device have high strength and rigidity, which can effectively distribute the concentrated stress at the connection point evenly over a larger area. This allows the force to be transferred to a wider area, avoiding stress concentration in local locations, thereby reducing structural deformation or damage caused by excessive stress and ensuring the stability of the connection point.

[0035] Furthermore, the elastic material of the buffer bar can absorb and dissipate the impact energy through its own elastic deformation when the steel structure is subjected to impact or vibration, thereby reducing the direct impact on the connection position of the steel structure. In this way, it can effectively buffer the energy transmitted by seismic waves to the steel structure, reduce the vibration response of the structure, protect the connection parts of the steel structure from damage, and improve the seismic performance of the steel structure.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] It should be noted that the structure and working principle of the above-mentioned steel structure main body 1, assembly plate 11 and other components are existing technologies and will not be described in detail here.

[0050] Example 1: Please refer to Figure 1 As shown, a modular steel structure includes a steel structure body 1, an assembly plate 11 is fixedly connected to the side wall of the steel structure body 1, and assembly holes are uniformly opened through the surface of the assembly plate 11. An auxiliary installation mechanism 2 is provided on the outside of the steel structure body 1, and the auxiliary installation mechanism 2 is used to realize the rapid and accurate assembly between the steel structure bodies 1.

[0051] Please refer to Figures 2 to 6 As shown, the auxiliary installation mechanism 2 includes an external gear ring 21 disposed outside the main steel structure 1. An internal gear ring 22 is fixedly connected inside the external gear ring 21. Limiting plates 23 are uniformly rotatably connected to the side walls of the external gear ring 21. Driven gear shafts 24 are installed on the side walls of the limiting plates 23. Assembly screws 25 are installed on the outside of the driven gear shafts 24. The assembly screws 25 correspond to the assembly holes opened on the surface of the assembly plate 11. Adsorption rings 26 are installed on the outer walls of the assembly screws 25. The adsorption rings 26 are rotatably connected to the outer walls of the external gear ring 21.

[0052] It should be noted that the driven gear shaft 24 consists of gears and a main shaft. The gears in the driven gear shaft 24 are all meshed with the internal gear ring 22, and the main shaft in the driven gear shaft 24 is rotatably connected to the limiting plate 23. The mounting screw 25 is made of ferromagnetic metal, and the adsorption ring 26 is made of magnetic material. Both the external gear ring 21 and the internal gear ring 22 are designed to be telescopic, and elastic cables are installed inside them. In their initial state, both the external gear ring 21 and the internal gear ring 22 are regular circular shapes.

[0053] Specifically, the auxiliary installation mechanism 2 mentioned in this device is an auxiliary structure used during the process of splicing and installing the main steel structure 1. First, the outer toothed ring 21 is stretched to separate it, so that it can pass directly through the outside of the main steel structure 1. When the auxiliary installation mechanism 2 moves to the position of the assembly plate 11, it is then squeezed to restore it to its original shape, i.e., a regular circle. At this time, the worker only needs to attach the gear that matches the outer toothed ring 21 to the outer wall of the electric drill tool. Then, by starting the electric drill, the gear will drive the outer toothed ring 21 to rotate synchronously, thereby completing the synchronous installation of multiple assembly screws 25. Moreover, the above-mentioned workflow, such as installing the matching gear on the outer wall of the electric drill tool, can be performed before splicing and installing the main steel structure 1. Therefore, in the actual installation between the main steel structure 1, not many steps are required.

[0054] When the gear outside the electric drill drives the external gear ring 21 to rotate, since the driven gear shaft 24 is engaged with the internal gear ring 22, the movement of the internal gear ring 22 will also drive the driven gear shaft 24 to rotate synchronously. In this way, the mounting screw 25 installed outside the driven gear shaft 24 can be installed into the corresponding mounting hole on the surface of the mounting plate 11 in a continuously rotating manner.

[0055] The adsorption ring 26 is made entirely of magnetic material and is magnetic, while the mounting screw 25 is made entirely of ferromagnetic metal. Therefore, when the mounting screw 25 approaches the adsorption ring 26, it will be attracted by the magnetic force of the adsorption ring 26. This magnetic force will generate a force in the axial direction of the mounting screw 25, causing it to tend to move towards the adsorption ring 26. This axial force will make the fit between the mounting screw 25 and the mounting hole tighter. For example, during the process of screwing the mounting screw 25 into the mounting hole, the magnetic force of the adsorption ring 26 will help the mounting screw 25 to better align with the mounting hole, and after screwing it in, the axial force will continue to be applied to maintain a certain pressure between the contact surfaces of the mounting screw 25 and the mounting hole.

[0056] Please refer to Figures 7 to 11 As shown, a double-layer temperature control mechanism 3 is provided inside the main steel structure 1. The double-layer temperature control mechanism 3 is used to specifically control the internal temperature of the main steel structure 1. The double-layer temperature control mechanism 3 includes a wiring assembly 31 installed inside the main steel structure 1. A support member 32 is installed on the outer wall of the wiring assembly 31.

[0057] It should be noted that the wiring assembly 31 is composed of a solid column and a cylindrical shell, and a perforated groove is provided between the solid column and the cylindrical shell. The wiring assembly 31 is used to lay out the wiring inside the steel structure body 1. The support member 32 is composed of a buffer rod and a support pad. The buffer rod is made of elastic material and the support pad is made of metal material.

[0058] It should be noted that a heat-conducting ring 33 is fixedly connected to the outer wall of the support 32, and an inner frame 34 is fixedly connected to the outside of the heat-conducting ring 33. Cylindrical chambers 35 are uniformly connected to the outside of the inner frame 34. An outer frame 36 is installed on the outer wall of the cylindrical chambers 35, and a sealing ring 37 is installed on the outside of the outer frame 36. The heat-conducting ring 33 is made entirely of boron nitride ceramic material, and the sealing ring 37 is made entirely of rubber material. The inner frame 34 and the outer frame 36 are both filled with heat-sensitive material. A through groove is uniformly opened through the outer wall of the inner frame 34, and the through groove is located between every two cylindrical chambers 35.

[0059] Specifically, the heat-conducting ring 33 is made entirely of boron nitride ceramic material. The crystal structure of boron nitride ceramic contains many bonds between atoms or ions. In boron nitride ceramic material, the bonding force between atoms or ions is relatively strong, which enables boron nitride ceramic material to effectively transfer heat energy.

[0060] Both the inner frame 34 and the outer frame 36 contain a thermosensitive material, which is a shape memory alloy. When heated, it changes shape, including expansion and other deformations, and returns to its original shape when the temperature drops. Specifically, it is a nickel-titanium shape memory alloy, which is mainly composed of nickel and titanium. The nickel content is about 49% to 51% atomic percentage, and the titanium (Ti) content is also controlled at about 49% to 51% atomic percentage. When it is subjected to heat input, the molecules will absorb this heat energy and convert it into molecular thermal motion. Molecular thermal motion will weaken the interaction force between molecules and change the equilibrium position between molecules, thereby causing the volume of the material to increase, i.e., thermal expansion.

[0061] According to the principle of heat transfer, heat always flows from a high temperature area to a low temperature area. When the external temperature of the main steel structure 1 is greater than the internal temperature, the temperature of the outer frame 36 is higher. The part of the heat-sensitive material near the outside will absorb heat first, so that the atoms in this part will gain more energy and the distance between the atoms will increase. This will cause the material to expand outward first, thereby filling and covering the splicing gaps between the main steel structures 1.

[0062] Similarly, when the internal temperature of the main steel structure 1 is higher than the external temperature, the temperature inside the main steel structure 1 is higher, and the temperature of the inner frame 34 is also higher. The part of the heat-sensitive material closer to the inside will preferentially absorb heat, and the arrangement between atoms will change, causing this part to expand first. Therefore, the heat-sensitive material tends to expand inward first. Since the outer wall of the inner frame 34 is uniformly provided with through slots, and the through slots are located between every two cylindrical chambers 35, when the heat-sensitive material in the inner frame 34 expands, the cylindrical chambers 35 will connect with the outer frame 36, thereby enabling heat exchange between the inside of the main steel structure 1 and the outside, playing a role in cooling and avoiding the adverse effects of excessively high internal temperature on the performance of the steel structure.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
