Description

Technical Field

[0001] This invention relates to the field of dome construction technology, and in particular to a dome assembly frame. Background Technology

[0002] In the assembly and welding of large building dome structures, the jig serves as a key auxiliary tool, undertaking the important task of providing support and positioning for the dome components. Its performance directly affects the accuracy of dome assembly, welding quality, and the overall construction efficiency of the project.

[0003] However, with the increasing diversity and complexity of architectural designs, traditional formwork has gradually revealed many insurmountable problems when dealing with dome structures of different shapes and design changes, which seriously restricts the smooth progress of dome construction and the improvement of project quality.

[0004] Traditional construction jigs are often custom-designed for specific dome structures, resulting in extremely limited applicability. For example, patent CN112609832B discloses a method for constructing an arch membrane for a double-shell dome in a nuclear power plant. While this method performs well for the specific double-shell dome structure of that nuclear power plant, its design is tightly bound to the dome's specific curvature and dimensions, with the dimensions, angles, and connection methods of each component of the jig remaining fixed. When encountering dome structures of different shapes, this type of jig cannot be directly applied and must be redesigned and manufactured, undoubtedly increasing engineering costs and extending the construction period.

[0005] Furthermore, the assembly jig for the AP1000 nuclear power plant dome disclosed in patent publication number CN203284883U also has similar problems. This jig is specifically designed for the AP1000 nuclear power plant dome. While it uses less material, is easy to operate, and is easy to disassemble and transport, its structure is also optimized for domes with specific geometric shapes. For domes with irregular shapes or special design requirements, its positioning and support effects are significantly reduced, making it difficult to meet diverse construction needs.

[0006] Furthermore, the positioning and welding of traditional jigs present significant challenges for specific dome structural shapes. In terms of positioning, traditional jigs typically rely on simple mechanical positioning methods, resulting in low accuracy and difficulty in ensuring the precise installation of dome components, easily leading to dimensional deviations in the assembled dome structure. During welding, the insufficient stability of the jig makes it susceptible to deformation due to welding thermal stress and external forces, thus affecting welding quality and increasing subsequent correction work.

[0007] Therefore, there is an urgent need for a novel dome assembly jig. This jig can flexibly adjust its support and positioning methods according to the shape and size requirements of different dome structures, achieving multi-purpose functionality and greatly improving its versatility and applicability, effectively reducing project costs and construction time. During the welding process, the jig exhibits good stability and resistance to deformation, effectively reducing the impact of welding thermal stress and external forces on the jig, ensuring welding quality, reducing subsequent correction work, and improving construction efficiency and project quality. Summary of the Invention

[0008] The present invention aims to solve the problems of the traditional jigs in the prior art, such as limited applicability to dome structures of different shapes, and difficulties in positioning and welding.

[0009] To address the above problems, the present invention provides a dome assembly frame, comprising:

[0010] The positioning ball seat and the connecting rod connecting the positioning ball seat, as well as the auxiliary connection device provided in the positioning ball seat and the connecting rod;

[0011] The positioning ball seat includes a support base and a spherical shell that is fixedly connected to the support base. The spherical shell has a hollow structure, and the connecting rod has a tubular structure. The auxiliary connection device includes an auxiliary receiving component and an auxiliary connecting component. The auxiliary receiving component includes several receiving ears that are fixedly installed in the positioning ball seat. The auxiliary connecting component includes an auxiliary connecting rod that passes through the connecting rod. The auxiliary connecting rod includes a tension locking device for locking the receiving ears.

[0012] Preferably, the auxiliary receiving component includes a receiving support column fixedly disposed in the positioning ball seat, a plurality of receiving ears disposed at equal angles on the receiving support column, a plurality of equally distributed receiving holes formed between the receiving support column and the receiving ears, and a docking opening corresponding to the position of the receiving holes opened on the spherical shell.

[0013] Preferably, the tension locking device includes several tension springs fixedly connected to the middle position of the auxiliary connecting rod, and locking buckles fixedly disposed at both ends of the auxiliary connecting rod, the locking buckles locking the receiving ear through the receiving hole.

[0014] Preferably, the connecting rod can be inserted into the docking opening, and receiving slots for accommodating at least part of the receiving ears are provided at both ends of the connecting rod;

[0015] When both ends of the connecting rod are connected to positioning ball seats through auxiliary connecting components, the connecting rod abuts against the receiving ear through the docking opening.

[0016] Preferably, there is one tension spring, which is fixedly connected to the center of the auxiliary connecting rod.

[0017] Preferably, there are two tension springs, which are fixedly connected to both sides of the middle area of ​​the auxiliary connecting rod, and the two tension springs are symmetrically distributed about the central axis of the auxiliary connecting rod.

[0018] Preferably, there are two tension springs, which are fixedly connected to both ends of the auxiliary connecting rod, and the end of each tension spring away from the auxiliary connecting rod is fixedly connected to the locking buckle of the corresponding end.

[0019] Preferably, the receiving support column and the support base are located on the same axis, and the two ends of the receiving support column are fixedly connected to the inner wall of the spherical shell.

[0020] The beneficial effects of this invention are as follows:

[0021] In this invention, the positioning ball seat and the connecting rod are connected by an auxiliary connection device. The receiving ears are set at equal angles on the receiving support column to form evenly distributed receiving holes. The connecting rod can be inserted into the docking opening and the receiving ears can be locked by the auxiliary connection component. This design makes the connection position between each component precise and fixed, and can provide basic positioning for the dome structure when welding the jig, ensuring the accuracy of the relative position of each component during the assembly process, improving the assembly accuracy, and ensuring that the final welded dome structure meets the design requirements.

[0022] The tension locking device includes a tension spring and a locking buckle, which securely connects the connecting rod to the positioning ball seat. The tension spring provides a certain tension, allowing the locking buckle to reliably lock the receiving ear, preventing loosening during welding, ensuring the stability of the assembly platform during welding, and providing good support conditions for welding work.

[0037] The technical solution of the present invention will now be described with reference to the accompanying drawings. However, the described embodiments are only some embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 11 As shown, the present invention provides a dome assembly frame, including a positioning ball seat 10 and a connecting rod 11 connecting the positioning ball seat 10, as well as an auxiliary connection device 12 disposed in the positioning ball seat 10 and the connecting rod 11;

[0039] The positioning ball seat 10 includes a support base 101 and a spherical shell 102 fixedly connected to the support base 101. The spherical shell 102 has a hollow structure. The connecting rod 11 has a tubular structure. The auxiliary connection device 12 includes an auxiliary receiving component 121 and an auxiliary connecting component 122. The auxiliary receiving component 121 includes a plurality of receiving ears 1211 fixedly disposed in the positioning ball seat 10. The auxiliary connecting component 122 includes an auxiliary connecting rod 1221 passing through the connecting rod 11. The auxiliary connecting rod 1221 includes a tension locking device 1223 for locking the receiving ears 1211.

[0040] like Figures 2 to 5 As shown, in this embodiment, the auxiliary receiving component 121 includes a receiving support column 1212 fixedly disposed in the positioning ball seat 10, a plurality of receiving ears 1211 disposed at equal angles on the receiving support column 1212, a plurality of equally distributed receiving holes 1213 formed between the receiving support column 1212 and the receiving ears 1211, and a docking opening 1021 corresponding to the position of the receiving holes 1213 is provided on the spherical shell 102.

[0041] In this embodiment, the positioning ball seat 10 is the basic support component of the jig frame, which is formed by the fixed connection of the support base 101 and the spherical shell 102.

[0042] Specifically, the support base 101 is typically designed as a rectangular flat plate. This shape provides a large contact area, evenly distributing the weight transmitted from the upper structure and ensuring the positioning ball seat 10 is placed stably on the ground or other supporting surfaces. The four corners of the plate can be chamfered to prevent scratching operators or damaging other objects during handling and installation. High-strength steel, such as Q345 steel, is generally used. This type of steel has good mechanical properties and can withstand large loads, ensuring that the support base 101 will not deform or be damaged during long-term use.

[0043] To further improve the strength and stability of the support base 101, reinforcing ribs can be installed at the bottom of the plate. The reinforcing ribs can be made of channel steel or angle steel, and are welded to the bottom of the plate at certain intervals and in a certain direction to form a grid-like reinforcing structure.

[0044] Specifically, the spherical shell 102 is a hollow hemispherical structure, and its diameter is designed according to the overall size and load-bearing requirements of the jig. The hemispherical design ensures that the spherical shell 102 has the same mechanical properties in all directions, enabling it to evenly bear the force from the connecting rod 11. High-strength steel, such as Q345 steel, is also used, consistent with the material of the support base 101, to ensure the structural strength of the entire positioning ball seat 10. The spherical shell 102 is fixedly connected to the support base 101 by welding. During welding, it is essential to ensure that the weld quality meets relevant standards, employing full penetration welding, and undergoing non-destructive testing, such as ultrasonic testing, to ensure that there are no internal defects in the weld and that the connection is firm and reliable.

[0045] In this embodiment, the receiving support column 1212 and the support base 101 are located on the same axis, and the two ends of the receiving support column 1212 are fixedly connected to the inner wall of the spherical shell 102.

[0046] Specifically, the receiving support column 1212 is fixedly disposed inside the spherical housing 102 and is located on the same axis as the support base 101. The receiving support column 1212 has a cylindrical structure, and its diameter is designed according to the size and number of receiving ears 1211. The two ends of the receiving support column 1212 are fixedly connected to the inner wall of the spherical housing 102 by welding, and the welding requirements are the same as those for the connection between the spherical housing 102 and the support base 101.

[0047] Several receiving ears 1211 are arranged at equal angles on the receiving support column 1212. For example, if six receiving ears 1211 are provided, the included angle between adjacent receiving ears 1211 is 60°. The receiving ears 1211 are rectangular block structures, and their dimensions should be designed according to the dimensions of the receiving slots 111 on the connecting rod 11 to ensure accurate fit. The receiving ears 1211 are fixed to the receiving support column 1212 by welding. During welding, it should be ensured that the receiving ears 1211 are perpendicular to the receiving support column 1212 and that the weld quality is good. Several evenly distributed receiving holes 1213 are formed between the receiving support column 1212 and the receiving ears 1211. The shape of the receiving holes 1213 is rectangular, and their size should be able to accommodate the locking buckles 1225 on the auxiliary connecting rod 1221.

[0048] A mating opening 1021 corresponding to the receiving hole 1213 is provided on the spherical shell 102. The shape of the mating opening 1021 can be circular, rectangular, or any other desired shape, and its size should be slightly larger than the cross-sectional size of the connecting rod 11 so that the connecting rod 11 can be smoothly inserted. According to different receiving holes 1213 and their corresponding mating openings 1021, the assembly jig can be assembled into any desired three-dimensional or two-dimensional dome shape. The edges of the mating opening 1021 should be ground to make them smooth and flat to avoid scratching the connecting rod 11 or other components during the connection process.

[0049] like Figure 2 , Figure 3 and Figures 6 to 9 As shown, in this embodiment, the tension locking device 1223 includes a plurality of tension springs 1224 fixedly connected to the middle position of the auxiliary connecting rod 1221, and locking buckles 1225 fixedly disposed at both ends of the auxiliary connecting rod 1221. The locking buckles 1225 lock the receiving ear 1211 through the receiving hole 1213.

[0050] like Figure 7 As shown, in this embodiment, there are two tension springs 1224, which are fixedly connected to both ends of the auxiliary connecting rod 1221 respectively, and the end of each tension spring 1224 away from the auxiliary connecting rod 1221 is fixedly connected to the locking buckle 1225 of the corresponding end.

[0051] Specifically, there are two tension springs 1224, made of 60Si2MnA spring steel. The two tension springs 1224 are fixedly connected to both ends of the auxiliary connecting rod 1221, and the end of each tension spring 1224 furthest from the auxiliary connecting rod 1221 is fixedly connected to the corresponding locking buckle 1225. This structural design allows the tension springs 1224 to act directly on the locking buckle 1225, providing a more direct and effective pulling force, resulting in a tighter lock between the locking buckle 1225 and the receiving ear 1211. The connection between the tension springs 1224 and the auxiliary connecting rod 1221 and the locking buckle 1225 can be achieved by welding or snap-fit ​​connection, ensuring a secure connection.

[0052] The shape and size of the locking buckle 1225 are designed according to the receiving hole 1213, and the connection method with the auxiliary connecting rod 1221 is welding. When the connecting rod 11 is inserted into the docking opening 1021, the auxiliary connecting rod 1221 is pulled, and the tension springs 1224 at both ends are stretched, pulling the locking buckle 1225 toward the receiving ear 1211, so that it is firmly locked in the receiving hole 1213, ensuring that the connection between the connecting rod 11 and the positioning ball seat 10 is stable.

[0053] like Figure 8 As shown, in some embodiments, the tension spring 1224 is a single spring and is fixedly connected to the center of the auxiliary connecting rod 1221.

[0054] Specifically, the tension spring 1224 is a single unit, also made of high-strength spring steel, such as 60Si2MnA spring steel. This steel has good elasticity and fatigue strength, ensuring that the tension spring 1224 will not undergo plastic deformation or breakage during long-term use. The tension spring 1224 is fixedly connected to the center of the auxiliary connecting rod 1221, secured by welding or snap-fit ​​connection. During welding, ensure a firm and reliable connection between the spring and the auxiliary connecting rod 1221; for snap-fit ​​connection, select appropriate snap-fits to ensure connection strength.

[0055] Locking buckles 1225 are fixedly installed at both ends of the auxiliary connecting rod 1221. Their shape is rectangular or L-shaped, and the specific shape should be designed according to the size and shape of the receiving hole 1213 to ensure smooth insertion into the receiving hole 1213 and locking of the receiving ear 1211. Locking buckles 1225 are fixed to the auxiliary connecting rod 1221 by welding, with welding requirements identical to those for the tension spring 1224. When the connecting rod 11 is inserted into the mating opening 1021 and abuts against the receiving ear 1211, pulling the auxiliary connecting rod 1221 causes the locking buckles 1225 to enter the receiving hole 1213. The tension spring 1224 is stretched, generating tension that tightly fixes the locking buckles 1225 to the receiving ear 1211, thus achieving the connection between the connecting rod 11 and the positioning ball seat 10.

[0056] like Figure 9 As shown, in some embodiments, there are two tension springs 1224, which are fixedly connected to both sides of the middle area of ​​the auxiliary connecting rod 1221, and the two tension springs 1224 are symmetrically distributed about the central axis of the auxiliary connecting rod 1221.

[0057] Specifically, there are two tension springs 1224, both made of 60Si2MnA spring steel. The two tension springs 1224 are fixedly connected to both sides of the middle area of ​​the auxiliary connecting rod 1221, and are symmetrically distributed about the central axis of the auxiliary connecting rod 1221. This design provides greater tensile force and better stability compared to a single tension spring 1224. The tension springs 1224 are fixed to the auxiliary connecting rod 1221 by welding or snap-fit ​​connection, with connection requirements the same as in the first configuration.

[0058] The locking buckle 1225 is configured in the same way as in the above embodiment, and is fixedly installed at both ends of the auxiliary connecting rod 1221. Its shape and size are designed according to the receiving hole 1213, and it is fixed by welding. When the connecting rod 11 is connected to the positioning ball seat 10, the auxiliary connecting rod 1221 is pulled, and the two tension springs 1224 are stretched. The resulting tension makes the locking buckle 1225 firmly fixed on the receiving ear 1211, preventing the connection from loosening during the welding process.

[0059] like Figures 1 to 6 As shown, in this embodiment, the connecting rod 11 can be inserted into the docking opening 1021, and receiving slots 111 are provided at both ends of the connecting rod 11 to accommodate at least part of the receiving ear 1211; when both ends of the connecting rod 11 are connected to the positioning ball seat 10 through the auxiliary connecting assembly 122, the connecting rod 11 passes through the docking opening 1021 and abuts against the receiving ear 1211.

[0060] Specifically, the connecting rod 11 is a hollow cylindrical rod that connects different positioning ball seats 10 to form a complete jig structure. It uses the same Q345 high-strength steel as the positioning ball seats 10 to ensure that the connecting rod 11 has sufficient strength and rigidity to withstand the tensile and compressive forces generated during the assembly of the dome structure. The hollow design of the connecting rod 11 not only reduces its own weight, facilitating handling and installation, but also reduces material costs. The diameter of the hollow part should be rationally designed according to the dimensions of the connecting rod 11 and the load-bearing requirements, while ensuring sufficient internal space for the auxiliary connecting rod 1221 to pass through.

[0061] Both ends of the connecting rod 11 are provided with receiving grooves 111 that can accommodate at least part of the receiving ears 1211. The receiving grooves 111 are rectangular in shape, and their dimensions match the dimensions of the receiving ears 1211. The depth should be designed according to the actual situation to ensure accurate docking when the connecting rod 11 is connected to the positioning ball seat 10. The edges of the receiving grooves 111 should be chamfered to facilitate the entry of the receiving ears 1211. The connecting rod 11 can be inserted into the docking opening 1021 of the positioning ball seat 10. When both ends of the connecting rod 11 are connected to the positioning ball seat 10 through the auxiliary connecting assembly 122, the connecting rod 11 abuts against the receiving ears 1211 through the docking opening 1021. At this time, a stable connection structure is formed between the connecting rod 11 and the positioning ball seat 10, which can withstand various forces generated during the assembly and welding of the dome structure.

[0062] This invention has many applications, including but not limited to the following described scenarios:

[0063] During the construction of domes in large stadiums, theaters, exhibition halls, and other buildings, a large number of steel structural components need to be assembled and welded. This dome assembly jig can provide precise positioning and stable support for these steel structural components, ensuring the accurate assembly and welding quality of the dome structure and meeting the high requirements of structural precision and safety for large buildings.

[0064] Industrial plants typically have large spans and spaces, and their dome structures are also quite complex. Using this type of assembly frame, the size and shape of the frame can be flexibly adjusted according to the specific design requirements of the plant dome, enabling efficient assembly and welding of industrial plant domes of different specifications, ensuring construction progress and quality.

[0065] For dome projects with unique shapes, such as art buildings and theme park structures, the dome structure often has distinctive curves and shapes. This formwork's flexible connection method can adapt to the needs of these special shapes. By adjusting the connection position of the connecting rods and positioning ball seats, the assembly of specially shaped domes can be precisely achieved, providing strong support for the design and construction of creative buildings.
