[0045] As shown in Figure 1 An arch rib assembling method provided by an embodiment of the present application includes:

[0046] S100, the first arch rib 1 is placed at the first lying assembling jig 3, wherein the first inner web side 12 of the first arch rib 1 is in contact with the first bottom jig 31 of the first lying assembling jig 3, and the first inner web side 12 is a side for connecting with the second arch rib 2.

[0047] Specifically, the first arch rib 1 and the second arch rib 2 are two main components of the arch structure and are basic units of the arch structure. The first arch rib 1 is a main arch rib and is a main load-bearing part of the arch structure. It is usually designed as the longest and widest arch rib unit in the structure and bears the main load of the arch structure. The second arch rib 2 is a secondary arch rib that assists the main arch rib to bear the load. The first lying assembling jig 3 is used for supporting and positioning the components to be assembled and is usually made of high-strength steel material and has sufficient rigidity and carrying capacity to ensure that it does not deform during the assembly of the plate units to form a single arch rib segment. In the manufacture of a single segment of the first arch rib 1, the flat inner web is in contact with the bottom jig of the lying assembling jig, and then the plate units of the single segment of the first arch rib 1 are assembled. The plate units include a bottom plate, an inner web, a top plate, and an outer web. The end of the first bottom jig 31 away from the first inner web side 12 is fixed to the ground. The first arch rib 1 can be divided into four sides: the first bottom plate side 11, the first inner web side 12, the first top plate side 13, and the first outer web side 14.

[0048] S200, placing the second arch rib 2 at the second lying assembly jig 4, wherein the second inner web side 22 of the second arch rib 2 is in contact with the second bottom jig 41 of the second lying assembly jig 4, and the second inner web side 22 is the side for connecting with the first arch rib 1.

[0049] Specifically, when the single segment of the second arch rib 2 is manufactured, the flat second inner web 22 is in contact with the second bottom jig 41 of the second lying assembly jig 4, and then the plate unit assembly of the single segment of the second arch rib 2 is carried out. The end of the second bottom jig 41 away from the second inner web side 22 is fixed on the ground. The second arch rib 2 can be divided into four sides: the second bottom plate side 21, the second inner web side 22, the second top plate side 23, and the second outer web side 44.

[0050] S300, fixing the first anti-deformation tool 5 on the first arch rib 1 and fixing the second anti-deformation tool 6 on the second arch rib 2.

[0051] Specifically, the mounting points of the anti-deformation tools are determined on the first arch rib 1 and the second arch rib 2 respectively. These points are usually located at the weak parts of the arch rib or the places where deformation is easy to occur, such as the vicinity of the arch crown, the arch foot or the connection. The anti-deformation tools are fixed on the arch rib by welding. After installation, the fixing condition of each anti-deformation tool is carefully checked to ensure that they are firm and in the correct position. If any looseness or misalignment is found, it should be adjusted immediately.

[0052] S400, separating the first arch rib 1 with the fixed first anti-deformation tool 5 and the second arch rib 2 with the fixed second anti-deformation tool 6 from the first lying assembly jig 3 and the second lying assembly jig 4 respectively and moving them to the vertical assembly jig 8, wherein the first bottom plate side 11 of the first arch rib 1 is in contact with the vertical assembly jig 8, the second bottom plate side 21 of the second arch rib 2 is in contact with the vertical assembly jig 8, the first bottom plate side 11 of the first arch rib 1 is the side adjacent to the first inner web side 12, and the second bottom plate side 21 of the second arch rib 2 is the side adjacent to the second inner web side 22.

[0053] Specifically, the vertical assembly jig 8 is a vertical or inclined support structure, which is marked with positioning lines and positioning holes for positioning, ensuring that the bottom plate side of the arch rib can be accurately contacted with the vertical assembly jig 8. The first arch rib 1 fixed with the first anti-deformation tool 5 is carefully lifted from the first horizontal assembly jig 3 using a crane or other heavy lifting equipment. During lifting, ensure that the lifting ropes or lifting belts are evenly distributed to avoid additional pressure or bending on the arch rib. The first arch rib 1 fixed with the first anti-deformation tool 5 is slowly moved above the vertical assembly jig 8, and the first bottom plate side 11 is aligned with the area of the vertical assembly jig 8 to be contacted. The first bottom plate side 11 is adjacent to the first inner web side, and the first bottom plate side will be in direct contact with the vertical assembly jig 8. When the first arch rib 1 approaches the vertical assembly jig 8, use tools such as laser range finders or levels to accurately adjust the position of the arch rib to ensure that the first bottom plate side 11 corresponds to the positioning marks on the vertical assembly jig 8. The method of placing the second arch rib 2 on the vertical assembly jig 8 is the same as that of placing the first arch rib 1 on the vertical assembly jig 8, which will not be described one by one.

[0054] S500, connecting the first inner web side 12 and the second inner web side 22 to realize the assembly of the first arch rib 1 and the second arch rib 2.

[0055] Specifically, the first inner web side 12 of the first arch rib 1 and the second inner web side 22 of the second arch rib 2 are opposite, and a connecting rod is arranged between the first inner web side 12 and the second inner web side 22 to connect the first arch rib 1 and the second arch rib. A diagonal rod can be provided for connection, which can significantly enhance the stability of the arch rib structure. During the assembly of the arch rib, the diagonal rod plays a role similar to that of the diagonal brace in the triangular structure, which can effectively disperse the horizontal and vertical forces received by the arch rib, and improve the overall rigidity and stability of the arch rib. The diagonal rod and the first arch rib 1 and the second arch rib 2 can be firmly connected by welding.

[0056] In this embodiment, the first and second arch ribs are first placed on their respective horizontal assembly jigs, with the wider inner web plate contacting the bottom jig before assembly. The inner web plate is flatter than the bottom plate, providing stable support and preventing deformation of the arch ribs during assembly. The horizontal assembly jig is a temporary structure used to support and position components, effectively limiting the deformation of the arch ribs during assembly. After the individual arch rib segments are manufactured, anti-deformation fixtures are installed on the first and second arch ribs before they are transferred from the horizontal assembly jig. The anti-deformation fixtures effectively prevent structural deformation caused by self-weight or external forces during transfer, turning, and hoisting, ensuring the linear accuracy of the connection control surface. Next, the two arch ribs are transferred to the vertical assembly jig, so that the bottom plate sides of the first and second arch ribs contact the vertical assembly jig. The vertical assembly jig provides a vertical assembly platform, using it as a reference plane to ensure the correct vertical position of the first and second arch ribs during hoisting. Finally, using multiple diagonal bars to connect the first and second arch ribs not only enhances the overall connection strength between the two arch ribs, forming a robust structural system that can better withstand external loads and pressures, but also improves the overall safety and stability of the building.

[0057] Optionally, placing the first arch rib 1 on the first horizontal assembly frame 3 includes:

[0058] The first bottom plate side 11 of the first arch rib 1 is brought into contact with the first side frame 32 of the first horizontal assembly frame 3.

[0059] Specifically, such as Figures 2 to 4 As shown, Figure 3 for Figure 2 A schematic diagram of the cross-section of the first arch rib 1 obtained at the dashed line. Figure 4 This is a schematic diagram of the first arch rib 1 in the first horizontal assembly jig 3. During the manufacturing and initial assembly stages of the first arch rib 1, in addition to the first inner web plate side 12 contacting the first bottom jig 31 of the first horizontal assembly jig 3, the first bottom plate side 11 contacts the side jig 32 of the first horizontal assembly jig 3. This ensures that the first bottom plate side 10 maintains precise alignment and structural stability during assembly. The first side jig 32 supports and fixes the first bottom plate side 11, preventing unnecessary deformation during assembly and ensuring that the alignment of the bottom plate side conforms to the design. The end of the first side jig 32 away from the first bottom plate side 11 is fixed to the ground.

[0060] In this optional embodiment, the line shape of the bottom plate side can be strictly controlled by the contact between the bottom plate side and the side frame. The use of the side frame not only helps to maintain the line shape accuracy of the bottom plate side, but also provides additional support during the assembly process, reducing structural deformation caused by gravity or external forces, thereby improving the overall structural stability of the arch rib.

[0061] Optionally, the first anti-deformation tool 5 is fixed on the first arch rib 1, comprising:

[0062] The first anti-deformation tool 5 is fixed on the first inner web side 12 and the first bottom plate side 11.

[0063] Specifically, as shown in Figure 5 , Figure 5 The first anti-deformation tool 5 is fixed on the first arch rib 1 on the first horizontal assembly jig 3. During the manufacturing and assembly of the first arch rib 1, the first anti-deformation tool 5 is fixed on the first inner web side 12 and the first bottom plate side 11. The first anti-deformation tool 5 on the first inner web side 12 is mainly responsible for controlling the longitudinal deformation of the arch rib during the assembly process, while the first anti-deformation tool 5 on the first bottom plate side 11 focuses on preventing transverse deformation and twisting, especially during the process of detaching the arch rib from the horizontal assembly jig and subsequent transportation, turning and vertical assembly hoisting, to ensure that the linear precision of the arch rib is not affected.

[0064] In addition, Figure 6 The second anti-deformation tool 6 is fixed on the second arch rib 2 on the second horizontal assembly jig 4. The position of the second anti-deformation tool 6 fixed on the second arch rib 2 is consistent with the position of the first anti-deformation tool 5 fixed on the first arch rib 1.

[0065] In this optional embodiment, the application of the anti-deformation tool can significantly reduce the deformation of the arch rib during the manufacturing and assembly process, especially for the inner web side and the bottom plate side, which are the two key parts, which helps to maintain the overall stability and geometric precision of the arch rib structure.

[0066] Optionally, the first anti-deformation tool 5 is fixed on the first inner web side 12 of the first arch rib 1 and the first bottom plate side 11 of the first arch rib 1, comprising:

[0067] The first inner web side 12 is fixed with a first member 51, and the first bottom plate side 11 is fixed with a second member 52, wherein the first anti-deformation tool 5 is connected by the first member 51 and the second member 52, and the connection angle between the first member 51 and the second member 52 is a preset angle, and the preset angle is the angle formed by the plane where the first inner web side 12 and the first bottom plate side 11 are located.

[0068] Specifically, as shown in Figure 7 and Figure 8As shown, the first anti-deformation tooling 5 is connected by a first component 51 and a second component 52. The first component 51 and the second component 52 are connected by setting the connection angle through the angle formed by the plane where the first inner web side 12 and the first bottom plate side 11 are located, which ensures that the first anti-deformation tooling 5 can be closely combined with the arch rib structure to provide the best anti-deformation effect, and the connection method can adopt the welding method. The first component and the second component can be made of steel materials with good mechanical properties and low cost. The first component 51 is fixed with the first inner web side 12 of the first arch rib 1, and the second component 52 is fixed with the first bottom plate side 11 of the first arch rib 1. The fixed method can adopt the spot welding method, and the spot welding method can complete the fixing work in a short time, is easy to disassemble, is convenient for subsequent surface treatment and maintenance work, and improves the production efficiency.

[0069] In this optional embodiment, the first anti-deformation tooling ensures the geometric precision of the arch rib during the assembly process, especially for the inner web side and the bottom plate side, which ensures the linear precision of these parts and prevents the deformation of the arch rib during the assembly process, thereby maintaining the stability and integrity of the arch rib structure. The first component is fixed with the first inner web side of the first arch rib to ensure that the longitudinal deformation of the arch rib during the assembly process can be effectively prevented. The second component is fixed with the first bottom plate side of the first arch rib to ensure that the transverse deformation of the arch rib during the assembly process can be effectively prevented. The anti-deformation tooling provides sufficient support force on the inner web side and the bottom plate side of the arch rib, effectively controls the deformation of the arch rib during the assembly process, and especially resists external force during the transportation, turning and vertical assembly lifting process.

[0070] Optionally, the first inner web side 12 is fixed with the first component 51, and the first bottom plate side 11 is fixed with the second component 52, comprising:

[0071] The first inner web side 12 is fixedly connected with the first outer side edge 5111, and the first bottom plate side 11 is fixedly connected with the second outer side edge 5211. The first component 51 comprises a first main plate 511 and a first web plate 512 connected with each other, the first outer side edge 5111 is an outer side edge of the first main plate 511, the second component 52 comprises a second main plate 521 and a second web plate 522 connected with each other, the second outer side edge 5211 is an outer side edge of the second main plate 521, and the included angle between the first outer side edge 5111 and the second outer side edge 5211 is the preset angle.

[0072] Specifically, the first component 51 comprises a first main plate 511 and a first web 512, wherein the first main plate 511 is the main plate of the first component 51, the first web 512 is the web of the first component 51, and the first main plate 511 is connected with the first web 512. The second component 52 comprises a second main plate 521 and a second web 522, wherein the second main plate 521 is the main plate of the second component 52, the second web 522 is the web of the second component 52, and the second main plate 521 is connected with the second web 522. The first outer side edge 5111 of the first main plate 511 of the first component 51 is fixedly connected with the first inner web side 12 of the first arch rib 1, and the second outer side edge 5211 of the second main plate 521 of the second component 52 is fixedly connected with the first bottom plate side 11 of the first arch rib 1. The angle between the first outer side edge 5111 and the second outer side edge 5211 is the preset angle. The connection mode can be selected as spot welding, which can complete the fixing work in a short time and improve the production efficiency. The outer side edge of the component is usually the part with strong load-carrying capacity, and through the fixation with the arch rib, the deformation that may occur during use can be effectively resisted, and the stability and safety of the entire structure are ensured. The surface area of the outer side edge is usually small, and the fixation with the outer side edge can simplify the processing and installation process.

[0073] In the optional embodiment, the first inner web side is fixedly connected with the first outer side edge, which can effectively enhance the overall rigidity and load-carrying capacity of the structure and avoid deformation caused by external pressure during use. By fixedly connecting the first bottom plate side with the second outer side edge, the effective connection surface between the components is increased, which is helpful to realize better load distribution and improve the long-term stability of the structure. The safety and durability under load are ensured, thereby guaranteeing the functionality and reliability of the structure in actual application.

[0074] Optionally, one face of the first main plate 511 is connected with one face of the first web 512, so as to obtain the first component 51 in T shape, and one face of the second main plate 521 is connected with one face of the second web 522, so as to obtain the second component 52 in T shape.

The angle between the first outer side edge 5111 and the second outer side edge 5211 is the preset angle. The connection mode can be selected as spot welding, which can complete the fixing work in a short time and improve the production efficiency. The outer side edge of the component is usually the part with strong load-carrying capacity, and through the fixation with the arch rib, the deformation that may occur during use can be effectively resisted, and the stability and safety of the entire structure are ensured. The surface area of the outer side edge is usually small, and the fixation with the outer side edge can simplify the processing and installation process. Figure 7As shown, the first member 51 is a T-shaped member composed of a first main plate 511 and a first web 512, and the second member 52 is a T-shaped member composed of a second main plate 521 and a second web 522. The first main plate can be cut from a plate material to a desired size, and the main plate is usually thick to enhance its load bearing capacity. The web is also cut from a plate material to a specified shape, which can be a rectangle with a width equal to or slightly smaller than the main plate and fixed at the center of the main plate. The web is usually thin to provide support in the longitudinal direction while ensuring weight reduction. The main plate and the web can be connected by welding. When connected, the narrower side of the first web is connected to the wider side of the first main plate, and the narrower side of the second web is connected to the wider side of the second main plate, forming a "T" shaped structure with good load bearing capacity and rigidity. This can effectively resist deformation of the arch rib during assembly, transportation and hoisting, and maintain the geometric accuracy of the arch rib.

[0076] In this optional embodiment, the fixation of the outer sides of the first main plate 511 and the second main plate 521 of the T-shaped member to the arch rib can effectively prevent deformation of the arch rib during assembly, and maintain the stability and integrity of the arch rib structure. The design of the T-shaped member ensures the geometric accuracy of the arch rib during assembly, especially for the two key parts of the inner web side and the bottom plate side, which ensures the linear accuracy of these parts.

[0077] Optionally, the first member 51 and the second member 52 are formed by cutting an H-shaped member 7, which includes the first main plate 511, the second main plate 521 and a web 71, and the first main plate 511 and the second main plate 521 are symmetrically arranged on both sides of the web 71 and connected by the web 71.

[0078] Optionally, the method further comprises:

[0079] cutting the web 71 along the symmetry plane of the first main plate 511 and the second main plate 521 to obtain the first member 51 and the second member 52.

[0080] In particular, as Figure 8As shown, the H-shaped member 7 is composed of a first main plate 511, a second main plate 521 and a web plate 71, wherein the first main plate 511 and the second main plate 521 are symmetrically arranged on both sides of the web plate 71 and connected by the web plate 71. The H-shaped member 7 is cut along the dashed line on the web plate 71 between the first main plate 511 and the second main plate 521 to form two T-shaped members. After the web plate 71 is cut, it is divided into a first web plate 512 and a second web plate 522. The first T-shaped member 51 includes the first main plate 511 and the first web plate 512, and the second T-shaped member 52 includes the second main plate 521 and the second web plate 522. The web plate 71 can be accurately cut along the center plane using a plasma cutting machine or a laser cutting machine to ensure smooth and neat cutting edges. The anti-deformation tool provides sufficient support force on the inner web plate side and the bottom plate side of the arch rib, effectively controlling the deformation of the arch rib during assembly, especially resisting external forces during transportation, turning and vertical assembly hoisting.

[0081] In this optional embodiment, the cross-sectional shape of the T-shaped member has high structural strength and rigidity, which can effectively resist bending and twisting of the arch rib during assembly, and maintain the geometric shape and dimensional accuracy of the arch rib. The design of cutting two T-shaped members from one H-shaped member not only simplifies the manufacturing process of the tooling, but also optimizes the use of materials, reduces material waste and reduces production costs. The symmetrical design of the T-shaped member makes the installation and disassembly process of the anti-deformation tooling more simple and efficient, which can be achieved without complex tools, improving production efficiency.

[0082] Optionally, the first arch rib 1 fixed with the first anti-deformation tooling 5 and the second arch rib 2 fixed with the second anti-deformation tooling 6 are respectively detached from the first horizontal assembly jig 3 and the second horizontal assembly jig 4 and moved to the vertical assembly jig 8, comprising:

[0083] The first bottom plate side 11 is in contact with the first jig 81 in the vertical assembly jig 8, and the second bottom plate side 21 is in contact with the second jig 82 in the vertical assembly jig 8, and the distance between the first jig 81 and the second jig 82 is a predetermined distance.

[0084] Specifically, as Figure 7As shown, during the assembly of the first arch rib 1 and the second arch rib 2, the first bottom plate side of the first arch rib 1 is fixed with the first jig 81 in the vertical assembly jig 8, and the second bottom plate side of the second arch rib 2 is fixed with the second jig 82 in the vertical assembly jig 8. The fixing is to ensure that the overall structure of the assembled arch rib meets the design requirements. The distance between the first jig 81 and the second jig 82 must be strictly controlled within the preset distance range. This preset distance is determined according to the size of the arch rib, the design requirements, and the connection method between the arch ribs, to ensure accurate butt joint of the assembled arch rib and maintain the stability of the structure. The end of the first jig 81 away from the first bottom plate side 11 and the end of the second jig 82 away from the second bottom plate side are fixed to the ground.

[0085] In this optional embodiment, by precisely controlling the distance between the first jig and the second jig, the position accuracy of the arch rib during assembly can be ensured, avoiding inaccurate butt joint of the arch rib due to distance errors, and improving the overall accuracy of arch rib assembly. It helps to maintain the structural performance of the arch rib during use, prolongs the service life of the arch rib, and reduces long-term maintenance costs.

[0086] Optionally, after connecting the first inner web side 12 and the second inner web side 22, the method further comprises:

[0087] removing the first anti-deformation tooling 5 fixed on the first arch rib 1 and the second anti-deformation tooling 6 fixed on the second arch rib 2;

[0088] polishing the target area on the first arch rib 1 and the second arch rib 2, wherein the target area is the area on the first arch rib 1 and the second arch rib 2 where the anti-deformation tooling is fixed.

[0089] Specifically, in the final stage of arch rib assembly, once the assembly accuracy is confirmed, the next step is to remove the anti-deformation tooling used to ensure the stability of the arch rib structure before. These toolings are fixed on the arch rib by spot welding during assembly, and now the anti-deformation tooling needs to be removed to restore the complete appearance and structure of the arch rib. After removing the anti-deformation tooling, the target area of the first arch rib and the second arch rib 2 is polished. The target area refers to the area on the arch rib where the anti-deformation tooling is fixed, i.e. the spot welding area. Polishing the spot welding area removes the marks left by the welds, smoothens the surface, and prevents the spot welding area from becoming a stress concentration point, while preparing for subsequent surface treatment (such as painting, corrosion prevention, etc.). Polishing can be done manually or with electric tools such as a grinder, a sander, etc. It is necessary to ensure that the polished surface is smooth and flat, without obvious marks or defects.

[0090] In this optional embodiment, the anti-deformation tooling is removed and the spot-welded areas are ground, which restores the integrity and aesthetics of the surface of the arch rib. Grinding the spot-welded areas can eliminate the stress concentration points that may exist, avoid cracks or corrosion in the future in these areas, and more evenly and effectively cover the surface of the arch rib whether it is painted or corrosion treated, thereby improving the safety and durability of the arch rib structure.

[0091] Although the present application has been disclosed with reference to the above embodiments, the protection scope of the present application is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications will fall within the protection scope of the present application.
