Description

Technical Field

[0001] The present invention relates to the field of bridges and building structures, and particularly to an intelligent construction method and system for a steel web composite structure based on a spatial coordinate system. Background Art

[0002] In the fields of construction, bridges, steel structures, and composite structure engineering, corrugated plates are widely used in butt joints with cylindrical members such as steel pipes due to their good flexural stiffness and lightweight characteristics, and serve as an important part of the steel webs of composite structure bridges. However, the connection method between corrugated plates and steel pipes in the prior art has significant defects, seriously restricting the safety, durability, and aesthetics of the structure.

[0003] Currently, in composite structure engineering, as the steel web, the butt joint between corrugated plates and steel pipes mainly adopts the following method: directly attaching a flat steel plate to the bottom of the corrugated plate and fixing it to the surface of the steel pipe by welding through this flat steel plate. Although this method is simple to operate, it has the following key problems:

[0004] Too small welding contact surface: The planar shape of the attached flat steel plate cannot effectively match the curved surface of the steel pipe, and the actual welding contact area is only a linear or dot-like area, resulting in a significant reduction in welding strength. Research shows that the shear strength of such welded joints is less than 40% of the theoretical value and is prone to fatigue failure under dynamic loads.

[0005] Low durability: The narrow welding surface is easily affected by environmental corrosion and stress concentration, and cracks or even fractures are likely to occur in the weld area, significantly shortening the service life of the structure; statistics show that the average maintenance cycle of such connection methods is shortened by more than 50% compared with traditional welded structures.

[0006] Poor aesthetics: The exposed attached flat steel plate destroys the original streamline design of the corrugated plate, resulting in a protruding and uneven interface, which is difficult to meet the strict requirements of modern engineering for aesthetic effects.

[0007] Lack of adaptability: The prior art does not perform targeted cutting treatment on the corrugated plate and cannot form a matching contact surface according to the curvature of the steel pipe, restricting the application in special-shaped structures or high-precision assembly scenarios.

[0008] With the development of large composite structure projects towards lightweight, high durability, and refined design, the defects of traditional connection methods have become increasingly prominent. For example, in cross-sea bridges or high-rise buildings, the durability of connection nodes directly affects the safety life of the overall structure; in the field of public buildings, the aesthetics of interfaces has become an important indicator for design evaluation. In addition, the limitations of the prior art also lead to material waste (such as additional flat steel plates requiring extra processing) and increased construction costs.

[0009] Therefore, there is an urgent need for an innovative technology that can form a groove contact surface that perfectly matches the curvature of the steel pipe by performing high-precision cutting on the corrugated plate, thereby significantly increasing the welding area, structural strength, and aesthetics, while reducing maintenance costs. This improvement not only fills the gap in existing technologies but also has important significance for promoting the technological upgrading of steel structure projects. Summary of the Invention

Through the dynamic matching of the coordinate system and cutting parameters, the contact surface matching problem is actually solved. The contact surface after cutting is no longer a standard cosine function, improving the cutting accuracy; based on the standardized cutting process and combined with the mathematical model of the present invention, manual intervention is reduced, the cutting accuracy and consistency are improved, and the accuracy and efficiency are greatly enhanced, especially suitable for mass production.

[0057] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments. For the convenience of description, only parts related to the embodiments of the present invention are shown. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0058] Embodiment 1

[0059] As Figure 1 shown is a flowchart of the intelligent construction method for the steel web composite structure based on the space coordinate system of the present invention. The method includes:

[0060] S101, project the first corrugated plate frontally into a planar corrugated curve;

[0061] As Figure 2 shown is a graph of the front projection of the corrugated plate of the present invention as a planar corrugated curve. The corrugated plate has an arc-shaped fold angle, and the arc-shaped fold angle refers to the arc-shaped bending part of the transition between adjacent wave peaks and wave valleys on its plate surface. It is a continuous and smooth arc that connects the wave peak and the wave valley, similar to a part of a circular arc; when viewed from the side, the corrugated plate presents a periodically repeated wave shape, and the arc-shaped fold angle is where the wave rises and turns;

[0062] In this embodiment, a corrugated plate with an arc-shaped fold angle is adopted, which enhances the overall structural performance of the steel web composite structure. Compared with flat steel plates and folded steel plates, it has better compressive and bending resistance and can disperse stress;

[0063] The frontal projection means vertically mapping the bottom of the first corrugated plate onto a plane to form a planar corrugated curve. As Figure 2as shown;

[0064] In order to distinguish the corrugated plates before and after the intelligent construction of the steel web composite structure, in this embodiment, the corrugated plates are divided into a first corrugated plate and a second corrugated plate, where the first corrugated plate is the corrugated plate of the prior art, and the second corrugated plate is the corrugated plate after intelligent construction (cutting) based on the space coordinate system of the present invention; when drawing a schematic diagram, for the convenience of understanding, Figure 4 、 Figure 5 it is only a simple schematic diagram, and only the approximate appearance after fitting and docking is shown in the figure. In the figure, 1 is the first corrugated plate and 2 is the steel pipe (i.e., the circular steel pipe);

[0065] S102, establish a space coordinate system including the X, Y, and Z axes according to the plane corrugated curve;

[0066] Establish a space coordinate system according to the relative position after the docking of the first corrugated plate and the steel pipe. The origin of the X, Y, and Z axes is O, as Figure 2 、 Figure 3 shown, where the X axis is the distance of the plane corrugated curve (including wave crests, wave troughs, etc.) relative to the Y axis;

[0067] The Y axis is the space longitudinal through center axis of the contact surface curve after the first corrugated plate and the steel pipe are fitted and docked. For the convenience of understanding, as Figure 5 , the Y axis can be simply understood as the straight coordinate axis passing through the midpoint between the wave crest and the wave trough of the first corrugated plate;

[0068] The Z axis is the height of the first corrugated plate;

[0069] In the space coordinate system of the X, Y, and Z axes, the projection of the X and Z axes on the Y axis is the X - O - Z coordinate system, Figure 3 as shown in the schematic diagram of the dynamic cutting of the corrugated plate;

[0070] S103, according to the space coordinate system, formulate a cutting function and a cutting angle , and obtain a reference cutting point Q and a target cutting point B, specifically:

[0071] S1031, create the prerequisite conditions for completely cutting the first corrugated plate: , the reference cutting point Q is on the X axis and below it;

[0072] In reality, generally, a steel pipe with a diameter larger than the thickness of the first corrugated plate (here the thickness refers to the value of the wave crest minus the wave trough) is docked with the first corrugated plate. Therefore, when cutting the first corrugated plate, there must be prerequisite conditions to ensure that the first corrugated plate can be completely cut. The complete cutting means that when using a cutter to cut the first corrugated plate, the edge of the first corrugated plate after cutting will not be too thick (i.e., not reaching the position of the wave crest or wave trough) or too thin (i.e., the cutting area exceeds the position of the wave crest or wave trough);

[0073] S1032. Assume that the planar wave curve of the first corrugated plate satisfies the standard cutting cosine function. Draw a circle with O' as the center and r as the radius. The circle intersects the X-axis at A and -A;

[0074]

[0075] Draw a straight line through the center O' , , that is parallel to the X-axis;

[0076] The diameter of the steel pipe is 2r, and the circle is the cross-section of the steel pipe;

[0077] , A is the amplitude of the wavy line curve, that is, the distance from the coordinate origin O to the wave crest or wave trough, , is the diameter of the circle, which can also be understood as the diameter of the steel pipe; the wavelength is S or the wave period of the wavy line curve is S, and each period S = 2 ;

[0078] S1033. Obtain the cutting angle ;

[0079] Such as Figure 3 , AO'A is the cutting angle , randomly take a point z1 in the A - A arc interval, draw a perpendicular line to the X-axis, and intersect the X-axis at x1 and the straight line at point x2. z1x2 is perpendicular to O'x2;

[0080] Among them , , ,

[0081] In actual cutting, dynamically adjust the reference cutting point Q. The reference cutting point , y , -A < x < A

[0082] There is

[0083] For X - Y - O', S = T, which is the wave period. There is

[0084] And

[0085] Also

[0086]

[0087]

[0088] For x to satisfy simultaneously ①

[0089] According to the interior angle theorem of a triangle, the cutting angle satisfies , and Z In the area where, referring to the cutting point Q being on the X-axis and below it, can the first corrugated plate be completely cut;

[0090] For , there is

[0091] ②

[0092] Substitute ① into ② to obtain the equation of z with respect to y:

[0093] S1034, according to the said cutting angle , obtain the reference cutting point Q;

[0094] The coordinates of the said reference cutting point Q are ( , y, )

[0095] For the coordinates of the reference cutting point Q (which can also be understood as the target cutting point B without deformation compensation) to satisfy simultaneously:

[0096]

[0097] However, since the present invention aims to make the structure more stable after the first corrugated plate is butted with the steel pipe, a deformation compensation coefficient needs to be introduced for the coordinates of the reference cutting point Q, so as to further obtain the target cutting point B after deformation compensation,

[0098] And in the X-O-Z axis,

[0099] ,

[0100] That is, , 1

[0101] By combining,

[0102] :

[0103]

[0104] d is a constant, and its value is , is a constant related to parameters such as the elastic modulus, Poisson's ratio, and density of the material;

[0105] S104. According to the cutting function and cutting angle , reference cutting point Q and target cutting point B, cut the first corrugated plate to generate a second corrugated plate with a contact surface curve space at the bottom, and the second corrugated plate fits and docks with the steel pipe through the contact surface curve space;

[0106] The contact surface curve space is the curve space where the second corrugated plate completely fits and docks with the steel pipe, and it is a complex curved surface space;

[0107] In step S104, a steel cutter cuts the first corrugated plate according to the cutting function, cutting angle , reference cutting point Q and target cutting point B to generate a second corrugated plate with a contact surface curve space at the bottom;

[0108] The steel cutter is a cutter in the prior art that can cut steel materials such as traditional corrugated plates and steel pipes. The steel cutter can be a flame cutter, water cutter, laser cutter, plasma arc cutter, etc. in the prior art. In the present invention, a laser cutter and a plasma arc cutter are preferably used. During the cutting process, the cutting parameters of the steel cutter need to be controlled. The cutting parameters include cutting function, cutting angle, target cutting point, guide rail distance, nozzle inclination angle, drag amount, etc., to ensure that the flatness and perpendicularity of the cutting surface space of the corrugated plate (i.e., the contact surface curve space) match the steel pipe to be welded later;

[0109] By establishing a space coordinate system and deriving a cutting function, the present invention combines mathematical modeling with the physical cutting process to achieve high-precision cutting of the first corrugated plate. Especially in complex curved surface cutting, the coordinates of the dynamic reference cutting point Q, target cutting point B, and cutting angle are calculated, which has non-obviousness;

[0110] Considering factors such as amplitude, wavelength, and cutting angle, the reference cutting point Q and target cutting point B are dynamically determined through the cutting function to ensure that the contact surface curve space after cutting meets the geometric requirements;

[0111] Through the correction terms in the cutting function (such as introducing a square root term, displacement parameter, etc.), the curve deformation after cutting is indirectly compensated, implicitly adjusting the adaptability to the change law. By dynamically matching the coordinate system and cutting parameters, the contact surface matching problem is actually solved. The contact surface after cutting is no longer a standard cosine function, which is a pioneering technology;

[0112] By standardizing the cutting process (such as adjusting the guide rail distance, nozzle inclination angle, trailing amount, etc. in existing cutting technologies) and combining with the mathematical model of the present invention, manual intervention is reduced, cutting accuracy and consistency are improved, and both accuracy and efficiency are greatly enhanced, which is especially suitable for mass production;

[0113] The method proposed by the present invention can be adapted to different cutting technologies (such as flame cutting, plasma cutting, etc.), has good universality, expands the application scenarios of traditional cutting technologies, and has remarkable technical effects;

[0114] Existing cutting technologies mostly rely on empirical parameters or simple geometric models, while this invention realizes systematic innovation from theory to practice by introducing complex mathematical functions (such as the modified cosine function, cutting angle formula, deformation compensation coefficient) and three-dimensional coordinate systems, etc.;

[0115] Further, the specific content of step S104 is as follows:

[0116] S1041, the steel cutter cuts the first corrugated plate according to the cutting function, cutting angle , reference cutting point Q and target cutting point B, and generates a contact surface curve space;

[0117] S1042, collect the redundant steel cut, clean, cut or crush the redundant steel to make a welding core;

[0118] S1043, prepare a coating to wrap the welding core, and dry it to make a welding rod or welding wire;

[0119] S1044, the contact surface curve space fits and docks the first corrugated plate and the steel pipe through a welding torch via the welding rod or welding wire;

[0120] In construction engineering, when welding steel plates and steel pipes, using electrodes or welding wires of the same material as the base metal has the advantages of ensuring performance matching, improving welding quality, and enhancing structural stability. After the steel plates and steel pipes are welded, they jointly bear various loads imposed by the building structure. Using electrodes or welding wires of the same material as the base metal can better match the mechanical properties such as strength, hardness, and toughness of the weld with the steel plate, ensuring that when bearing dynamic loads (such as seismic forces) or static loads (such as the weight of the building itself), the weld will not deform or crack first due to mismatched mechanical properties, thus guaranteeing the safety and reliability of the entire structure. The structures in construction engineering may be exposed to various natural environments and face problems such as corrosion. Electrodes or welding wires of the same material as the steel plate have the same chemical composition as the steel plate and can cooperate with the steel plate in terms of chemical properties such as corrosion resistance, improving the corrosion resistance and durability of the welded joint in different environments and extending the service life of the structure. The metallurgical compatibility between electrodes or welding wires of the same material and the steel plate is better. During the welding process, they can be more evenly fused, reducing the occurrence of welding defects such as pores, slag inclusions, and lack of fusion. For example, in carbon dioxide gas shielded welding, using welding wires that match the steel plate material can make the welding process more stable, with uniform droplet transfer, thus effectively reducing the probability of welding defects. Due to the same material, the fluidity and wettability of the weld are more ideal during welding, which can better fill the weld gap, making the weld surface smoother and more uniform, with a beautiful shape. This not only improves the appearance quality of the structure but also helps to reduce stress concentration points and improve the overall performance of the structure. When welding with electrodes or welding wires of the same material as the steel plate, the mechanical properties and thermal expansion coefficients between the weld and the steel plate are relatively consistent. During the welding process and in use, when the structure is subjected to external forces or temperature changes, the stress can be more evenly distributed between the weld and the base metal, avoiding premature failure of the structure due to stress concentration at the weld, thus enhancing the stability of the entire structure. Electrodes or welding wires of the same material and the steel plate match in thermophysical properties, with relatively small thermal deformation during the welding process, and the deformation law is easier to predict and control. This is beneficial for ensuring the dimensional accuracy of the welded structure, reducing the need for correction work due to excessive deformation, improving construction efficiency, and also helping to maintain the stability and safety of the structure.

[0121] Furthermore, step S104 can specifically be:

[0122] The steel cutter cuts the first corrugated plate according to the cutting function, cutting angle , reference cutting point Q and target cutting point B to generate a contact surface curve space;

[0123] Collect the excess steel cut off, clean, cut or crush the excess steel to make steel powder;

[0124] The contact surface curve space welds the first corrugated plate and the steel pipe together through a welding torch using a welding rod or welding wire, and at the same time sprays the steel powder on the weld; during the cutting process of the steel cutter, a high-speed rotating grinding device is arranged near the cutting area. When the excess steel cut off falls, it is immediately ground into steel powder by the grinding device; during the steel plate welding process, the welding torch provides an electric arc or flame to melt the welding rod or welding wire (which can be a traditional welding rod or welding wire, or the welding rod or welding wire of the present invention), thereby realizing the connection of metals; during the welding process, the high temperature will expose the weld formed by welding and the surrounding metals to the air, making them prone to oxidation. In this embodiment, applying a layer of steel powder of the same material as the first corrugated plate during welding can play a certain protective role, preventing oxidation and corrosion; the steel powder can help the weld better adhere to the metal surface, prevent welding deformation, and can also increase the strength and hardness of the weld, improving the welding quality;

[0125] Through the systematic integration of mathematical modeling and dynamic cutting technology, the present invention proposes an innovative method for butt welding of corrugated steel plates and steel pipes, solving the core problems such as small welding surface, low durability, and poor aesthetics in the prior art;

[0126] To verify the implementation effect of the present invention, the inventor selected multiple first corrugated plates with thicknesses of 10, 15, and 20 mm, widths of H800, H700, and H600, and lengths of 2 m, 5 m, and 10 m; the steel pipe diameters were selected as 600 mm, 1000 mm, and 1200 mm. Experiments (including tensile tests, bending tests, impact tests, and hardness tests) were carried out for the prior art and the technical solution of the present invention, and the experimental performance comparisons are shown in the following table:

[0127]

[0128]

[0129] Conclusion: For the technical solution of this embodiment, through stress distribution simulation analysis, the stress distribution of the welded joint is relatively uniform, and no obvious stress concentration points appear, indicating that the safety and reliability of the welded structure are relatively high; the deformation amount of the welded joint is small, indicating that the stiffness and stability of the welded structure are good;

[0130] In this embodiment, by establishing a space coordinate system and deriving a cutting function, the mathematical modeling is combined with the physical cutting process to achieve high-precision cutting of the first corrugated plate; according to factors such as the amplitude and wavelength of the first corrugated plate, the reference cutting point Q and the target cutting point B are dynamically determined through the cutting function to ensure that the contact surface curve space with the steel pipe after cutting meets the geometric requirements; a deformation compensation coefficient is introduced for the coordinates of the reference cutting point Q, especially the coordinates and cutting angles of the dynamic reference cutting point Q and the target cutting point B are introduced in the cutting of complex curved surfaces Calculation indirectly compensates for the curve deformation after cutting, implies an adaptive adjustment to the variation law, and actually solves the contact surface matching problem through the dynamic matching of the coordinate system and cutting parameters. The contact surface after cutting is no longer a standard cosine function, improving the cutting accuracy. Based on the standardized cutting process and combined with the mathematical model of the present invention, manual intervention is reduced, and the cutting accuracy and consistency are improved. The accuracy and efficiency are greatly enhanced, especially suitable for mass production.

[0139] In the space coordinate system of the X, Y, and Z axes, the projection of the X and Z axes with respect to the Y axis is the X - O - Z coordinate system;

[0140] The parameter module is connected to the coordinate system module and the cutting module and is used to formulate a cutting function and a cutting angle , and obtain a reference cutting point Q and a target cutting point B. Specifically:

[0141] Premises for creating a complete cut of the first corrugated plate: , the reference cutting point Q is on the X axis and below it;

[0142] In reality, generally, a steel pipe with a diameter greater than the thickness of the first corrugated plate (where the thickness refers to the value of the wave crest minus the wave trough) is butt-jointed with the first corrugated plate. Therefore, when cutting the first corrugated plate, there must be a prerequisite condition to ensure that the first corrugated plate can be cut completely. The so-called complete cutting means that when cutting the first corrugated plate with a cutter, the edge of the first corrugated plate after cutting will not be too thick (i.e., not cutting to the position of the wave crest or wave trough) or too thin (i.e., the cutting area exceeds the position of the wave crest or wave trough).

[0143] Assume that the wave curve of the first corrugated plate satisfies the standard cutting cosine function. Draw a circle with O´ as the center and r as the radius. The circle intersects the X-axis at A and -A;

[0144]

[0145] Draw a straight line through the center O´ , , that is parallel to the X-axis;

[0146] The diameter of the steel pipe is 2r, and the circle is the cross-section of the steel pipe;

[0147] , A is the amplitude of the wave curve, that is, the distance from the coordinate origin O to the wave crest or wave trough, , is the diameter of the circle, and can also be understood as the diameter of the steel pipe; the wavelength is S or the wave period of the wave curve is S, and each period S = 2 ;

[0148] Obtain the cutting angle ;

[0149] AO´A is the cutting angle , take any point z1 in the A - A arc interval, draw a perpendicular line to the X-axis, and intersect the X-axis at x1 and the straight line at point x2, and z1x2 is perpendicular to x2;

[0150] Among them , , ,

[0151] In actual cutting, dynamically adjust the reference cutting point Q, the reference cutting point , y , -A < x < A

[0157]

[0158] For x that satisfies ①

[0159] According to the interior angle theorem of a triangle, the cutting angle satisfy , and Z The reference cutting point Q is on or below the X-axis to completely cut the first wave plate.

[0160] for ,have

[0161] ②

[0162] Substituting ① into ②, we get the equation of z with respect to y:

[0163] According to the cutting angle , obtain the reference cutting point Q;

[0164] The coordinates of the reference cutting point Q are ( ,y, )

[0165] The coordinates of the reference cutting point Q (which can also be understood as the target cutting point B that has not been compensated for deformation) satisfy the following requirements:

[0166]

[0167] However, since the present invention aims to make the structure after the first corrugated plate and the steel pipe are butt-jointed more stable, it is necessary to introduce a deformation compensation coefficient k for the coordinates of the reference cutting point Q, so as to further obtain the target cutting point B after deformation compensation.

[0173]

[0174] d is a constant, and its value is , is a constant related to material elastic modulus, Poisson's ratio, density and other parameters;

[0175] A cutting module is connected to the parameter module and is used to , cutting the first corrugated plate with reference to the cutting point Q and the target cutting point B to generate a second corrugated plate with a contact surface curve space at the bottom;

[0176] The contact surface curve space is the curve space where the first wave plate (which can also be understood as the second wave plate) and the steel pipe are completely matched and connected, which is a complex curved surface space;

[0177] The cutting module may be a cutter capable of cutting the first wave plate, steel pipe and other steel materials in the prior art. The steel material cutter may be a flame cutter, a water cutter, a laser cutter, a plasma arc cutter and the like in the prior art. The present invention preferably uses a laser cutter and a plasma arc cutter. During the cutting process, the cutting parameters of the steel material cutter shall be controlled. The cutting parameters include a cutting function, a cutting angle, a target cutting point, a guide rail distance, a cutting nozzle inclination angle, a back drag and the like, so as to ensure that the flatness and verticality of the cutting surface space (i.e., the contact surface curve space) of the first wave plate are matched with the steel pipe to be welded later.

[0178] Furthermore, the system further comprises a welding module, which is connected to the cutting module and is used to fit and dock the first corrugated plate with the steel pipe through the contact surface curve space;

[0179] The welding module is a welding device for welding steel structures in the prior art;

[0180] The cutting module is further optimized for , cutting the first corrugated plate with reference to the cutting point Q and the target cutting point B and generating a contact surface curve space; collecting the excess steel cut off, cleaning, cutting or crushing the excess steel to make a welding core; preparing a coating to wrap the welding core, and drying it to make a welding rod or welding wire;

[0181] The welding module is also used to butt the first corrugated plate and the steel pipe together through the contact surface curve space and the welding rod or welding wire;

[0182] In construction projects, when welding steel plates and steel pipes, welding rods or welding wires made of the same material as the parent material are used, which has the advantages of ensuring performance matching, improving welding quality, and enhancing structural stability. After welding, steel plates and steel pipes must jointly bear various loads imposed by the building structure. Using welding rods or welding wires made of the same material as the parent material can better match the mechanical properties of the weld, such as strength, hardness, and toughness, with the steel plate, ensuring that when bearing dynamic loads (such as earthquake forces) or static loads (such as the weight of the building itself), the weld will not be the first to deform or crack due to mismatched mechanical properties, thereby ensuring Safety and reliability of the entire structure; structures in construction projects may be exposed to various natural environments and face problems such as corrosion. Welding rods or welding wires made of the same material as steel plates have the same chemical composition as steel plates and can work with steel plates in terms of chemical properties such as corrosion resistance to improve the corrosion resistance and durability of welded joints in different environments and extend the service life of the structure; welding rods or welding wires of the same material have better metallurgical compatibility with steel plates, and during the welding process, they can fuse more evenly, reducing the generation of welding defects such as pores, slag inclusions, and incomplete fusion; for example, in carbon dioxide gas protection During welding, using welding wire that matches the material of the steel plate can make the welding process more stable and the molten droplet transition uniform, thereby effectively reducing the probability of welding defects. Due to the same material, the fluidity and wettability of the weld are more ideal during welding, which can better fill the weld gap, make the weld surface smoother and more uniform, and have a beautiful shape, which not only improves the appearance quality of the structure, but also helps to reduce stress concentration points and improve the overall performance of the structure. When welding with welding rods or welding wires of the same material as the steel plate, the mechanical properties and thermal expansion coefficients between the weld and the steel plate are relatively consistent. During the welding process and use, when the structure is subjected to external force or temperature changes, the stress can be more evenly distributed between the weld and the parent material, avoiding premature damage to the structure due to stress concentration at the weld, thereby enhancing the stability of the entire structure. The welding rods or welding wires of the same material match the steel plate in thermal physical properties, and the thermal deformation generated during welding is relatively small, and the deformation law is easier to predict and control, which is conducive to ensuring the dimensional accuracy of the structure after welding, reducing the correction work required due to excessive deformation, improving construction efficiency, and also helping to maintain the stability and safety of the structure.

[0183] The cutting module is further optimized for , cutting the first corrugated plate with reference to the cutting point Q and the target cutting point B and generating a contact surface curve space; collecting the excess steel cut off, and cleaning, cutting or crushing the excess steel into steel powder;

[0184] The welding module is also used to butt the first corrugated plate with the steel pipe through the contact surface curve space using a welding rod or welding wire made of the same material as the first corrugated plate, and spray steel powder made of the same material as the first corrugated plate on the weld.

[0185] The cutting module is further optimized to cut the first corrugated plate according to the cutting function, cutting angle , reference cutting point Q and target cutting point B and generate a contact surface curve space; a high-speed rotating grinding device is arranged near the cutting area. When the redundant steel drops, it is immediately cleaned, cut or broken by the grinding device into steel powder;

[0186] During the steel plate welding process, the welding module provides an electric arc or flame to melt the welding electrode or welding wire (which can be a traditional welding electrode or welding wire, or the welding electrode or welding wire of the present invention), so as to realize the connection of metals; during the welding process, the high temperature will expose the weld formed by welding and the surrounding metals to the air and is prone to oxidation. In this embodiment, applying a layer of steel powder of the same material as the first corrugated plate during welding can play a certain protective role to prevent oxidation and corrosion; the steel powder can help the weld better fix on the metal surface, prevent welding deformation, and can also increase the strength and hardness of the weld and improve the welding quality;

[0187] Further, the welding module includes a processor, a first welding gun body, a second welding gun body and a third welding gun body, and the second welding gun body includes a high-pressure device and an atomizing device;

[0188] As Figure 6 shown, the first welding gun body, which is connected to the cutting module and the processor, is used to instantaneously melt the metals on the surfaces of the second corrugated plate and the steel pipe through a high-energy density such as a laser beam or an electron beam along the surface angle after the second corrugated plate is butted against the steel pipe, form a molten pool, and fill the molten pool with the welding electrode or welding wire to form a first welding surface;

[0189] The first welding surface is the outer surface of the molten pool formed on the surface of the included angle;

[0190] For easy understanding, Figure 6 only the surface angle after the second corrugated plate is butted against the steel pipe is shown, and the second corrugated plate and the steel pipe are omitted;

[0191] The processor, which is connected to the first welding gun body, the second welding gun body and the third welding gun body, is used to receive the start signal of the first welding gun body, judge the continuous working time of the first welding gun body. If the continuous working time of the first welding gun body is 0, it waits. If the continuous working time reaches 800 - 1000 milliseconds, it starts the high-pressure device of the second welding gun body; when the continuous working time reaches 1100 - 1300 milliseconds, it starts the third welding gun body and the atomizing device, and at the same time sends a jetting instruction to the third welding gun body and a spraying instruction to the atomizing device; it is also used to control the relative positions of the atomizing device of the first welding gun body, the second welding gun body and the third welding gun body. Among them, the nozzle of the first welding gun body that sprays the laser beam or electron beam, the spray head of the atomizing device of the second welding gun body and the jetting head of the third welding gun body form an isosceles triangle, asFigure 7 Shown is a schematic diagram of the relative positions of the key components of the welding module. The nozzle of the first welding torch body is at the vertex of an isosceles triangle, and the spray head of the atomization device of the second welding torch body and the air jet head of the third welding torch body are juxtaposed at two points at the bottom of the isosceles triangle; the length of the equal sides is 8 - 15 mm, preferably 10 mm; the spray line of the atomization device of the second welding torch body and the air jet line of the third welding torch body intersect at the first welding surface and form the second welding surface; it is also used to rotate and control the isosceles triangle according to the position of the first welding surface, that is, to ensure the formation of the first welding surface, and also to ensure that the first welding surface is just suitable for spraying steel powder and can form the second welding surface, and also to ensure that both the first welding surface and the second welding surface maintain running along the spatial side surface of the contact surface curve, so that the second corrugated plate and the steel pipe can be intelligently, semi-automatically and completely fitted for welding;

[0192] The high-pressure device, connected to the processor and the atomization device, is used to receive and execute the processor instructions, and is also used to high-pressure liquefy the steel powder of the same material as the first corrugated plate; at the same time, it notifies the processor, and the processor sends an air jet instruction to the third welding torch body;

[0193] The atomization device, connected to the high-pressure device and the processor, is used to receive the spray instruction, atomize the liquefied steel powder, and finally spray it onto the first welding surface to form the second welding surface;

[0194] The third welding torch body, connected to the processor, is used to receive the air jet instruction, and spray a protective gas onto the first welding surface or the second welding surface to form an isolation layer, preventing the oxygen in the air from contacting the molten second welding surface, thereby further increasing the strength and corrosion resistance of the weld;

[0195] Furthermore, the welding module further includes a bracket. The top of the bracket is located below the handle section of the welding module. The end of the bracket is in the shape of an umbrella arc and can have non-linear displacement, that is, the relationship between the applied force and the generated displacement is non-linear, which can play a role in temporarily locking the displacement state and is used to support the welding module to prevent fatigue;

[0196] Furthermore, the bracket is composed of a screw, a nut, a reverse device and a ball. When the screw or the nut rotates, the ball rolls in the thread raceway, realizing the conversion of rotary motion into linear motion or the conversion of linear motion into rotary motion. When rotating (axial rotation) or linearly moving (length expansion and contraction), due to certain pre-tightening force (set for the purpose of eliminating gaps and improving stiffness, etc.) and friction between the ball and the raceway, a certain force is required to drive, realizing high-precision, high-efficiency support and arc displacement;

[0197] Furthermore, the bracket is composed of an internal spline and an external spline. The external spline has longitudinal key teeth on the outer surface of the shaft, and the internal spline has corresponding key teeth on the inner surface of the hub hole. When the shaft needs to rotate axially, due to the meshing between the key teeth and a certain fitting accuracy, there will be a certain frictional resistance, etc., and a certain force is required to drive the rotation; when there is a need for relative movement (telescoping) axially, due to factors such as the interaction of the key teeth and surface friction, a certain force also needs to be applied to achieve telescoping; to relieve fatigue, save effort, improve efficiency, and not reduce the welding accuracy;

[0198] Similarly, this implementation has also been experimentally verified. It is the same as the comparison table in Embodiment 1 and will not be elaborated here;

[0199] In this embodiment, the first corrugated plate is orthographically projected into a planar corrugated curve by the digital module. The coordinate system module establishes a space coordinate system including the X, Y, and Z axes. The parameter module formulates a cutting function and a cutting angle according to the space coordinate system , obtains the reference cutting point Q and the target cutting point B. The cutting module cuts the first corrugated plate according to the cutting function, cutting angle , reference cutting point Q and target cutting point B to generate a second corrugated plate with a contact surface curve space at the bottom; in this embodiment, by establishing a space coordinate system and deriving a cutting function, the combination of mathematical modeling and physical cutting process is realized, achieving high-precision cutting of the first corrugated plate; according to factors such as the amplitude and wavelength of the first corrugated plate, the reference cutting point Q and the target cutting point B are dynamically determined through the cutting function to ensure that the contact surface curve space with the steel pipe after cutting meets the geometric requirements; a deformation compensation coefficient is introduced for the coordinates of the reference cutting point Q, especially the coordinates of the dynamic reference cutting point Q, target cutting point B and the cutting angle are introduced in the cutting of complex curved surfaces Calculation indirectly compensates for the curve deformation after cutting, implies an adaptive adjustment to the variation law, and actually solves the contact surface matching problem through the dynamic matching of the coordinate system and cutting parameters. The contact surface after cutting is no longer a standard cosine function, improving the cutting accuracy. Based on the standardized cutting process and combined with the mathematical model of the present invention, manual intervention is reduced, and the cutting accuracy and consistency are improved. The accuracy and efficiency are greatly enhanced, especially suitable for mass production. In this embodiment, the cutting module also collects the redundant steel cut, cleans, cuts or crushes the redundant steel to make welding cores. The welding cores are wrapped with flux and dried to make electrodes or welding wires. The welding module fits and docks the first corrugated plate with the steel pipe through the contact surface curve space and the electrodes or welding wires. Using electrodes or welding wires of the same material as the base material can better match the mechanical properties such as strength, hardness, and toughness of the weld with the steel plate, ensuring that when bearing dynamic or static loads, the weld will not deform or crack first due to mismatched mechanical properties, thus guaranteeing the safety and reliability of the entire structure. Further, the cutting module collects the redundant steel cut, cleans, cuts or crushes the redundant steel to make steel powder. The welding module simultaneously sprays steel powder of the same material as the first corrugated plate on the weld. Spraying a layer of steel powder of the same material as the first corrugated plate during welding can play a certain protective role, preventing oxidation and corrosion. The steel powder can help the weld better adhere to the metal surface, prevent welding deformation, and can also increase the strength and hardness of the weld, improving the welding quality. This embodiment also refines the welding module, making the system of this embodiment more creative. It also increases brackets to prevent fatigue, realizes high-precision and high-efficiency support and arc displacement, and improves efficiency.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
