[0002] In the process of nuclear power plant construction, the assembly and construction of steel containment, shielding plant, fuel plant and other structures are a crucial link in nuclear power construction. When the steel containment, shielding plant, fuel plant and other structures are sequentially assembled and welded from bottom to top, a scaffold needs to be built around the construction area from bottom to top simultaneously. For example, after the first layer of steel plate welding operation of the steel containment is completed, a first layer of scaffold platform must be built on its side to perform the second layer of steel plate welding operation of the steel containment.

[0003] Since the scaffold used in the construction process of the existing nuclear power plant structures such as steel containment, shielding plant, fuel plant is formed by connecting a large number of steel pipes, it not only consumes a large amount of human resources when building the scaffold around the nuclear power plant structure, but also requires a large amount of physical materials, increasing the construction cost. In addition, after the construction is completed, the built scaffold needs to be sequentially removed from top to bottom, which is time-consuming and labor-intensive, greatly increasing the construction period of the nuclear power plant. SUMMARY

[0004] The purpose of the utility model is to provide a supporting device for nuclear power plant structure construction to alleviate the technical problem that the scaffold used in the construction process of the existing nuclear power plant structures is formed by connecting a large number of steel pipes, which not only consumes a large amount of human resources when building the scaffold, but also requires a large amount of physical materials, increasing the construction cost, and the process of removing the scaffold after construction is completed is also time-consuming and labor-intensive, greatly increasing the construction period of the nuclear power plant.

[0005] In a first aspect, the utility model provides a supporting device for nuclear power plant structure construction, comprising a plurality of supporting components and a plurality of fixing members.

[0006] The plurality of fixing members are used to be fixed on the circumferential sidewall of the completed construction layer of the nuclear power plant structure; each supporting component is provided with a connecting member on one side, and the plurality of connecting members are used to be detachably connected with the plurality of fixing members one by one, so that the plurality of supporting components are sequentially distributed along the circumference of the completed construction layer and connected to form a ring-shaped supporting platform.

[0007] In an optional embodiment, the supporting component comprises a walking plate and a supporting frame, the walking plate is fixed on the supporting frame, and the side of the supporting frame close to the completed construction layer can abut against the outer wall of the completed construction layer.

[0008] In an optional embodiment, the connecting member is fixed to the side of the support frame close to the finished construction layer, and the side of the support frame close to the finished construction layer is provided with a protrusion, which is lower than the connecting member, and the protrusion is used to abut the circumferential side wall of the finished construction layer.

[0009] In an optional embodiment, a rubber cap is further included, which covers the protrusion.

[0010] In an optional embodiment, a supplementary plate is further included, which covers the gap between any two adjacent support assemblies.

[0011] In an optional embodiment, one side of the supplementary plate is hinged with the support assembly adjacent thereto.

[0012] In an optional embodiment, the fixing member is a hanging ring, and the connecting member is a hook with the opening facing downward.

[0013] In an optional embodiment, a hook is arranged on the support assembly.

[0014] In an optional embodiment, a guardrail assembly is further included, which is fixed to the side of each support assembly away from the finished construction layer.

[0015] In an optional embodiment, a reinforcing structure is further included, which is detachably connected between the guardrail assemblies of any two adjacent support assemblies.

[0016] The utility model provides a support device for nuclear power station structure construction, which comprises a plurality of support assemblies and a plurality of fixing members; the plurality of fixing members are fixed to the circumferential sidewall of the completed layer of the nuclear power station structure at intervals along the circumferential direction of the completed layer; each support assembly is provided with a connecting member on one side, and the plurality of connecting members are detachably connected with the plurality of fixing members one by one, so that the plurality of support assemblies are sequentially distributed along the circumferential direction of the completed layer and are spliced to form an annular support platform. The support device for nuclear power station structure construction is used in the splicing and welding construction process of the structures such as the steel containment vessel, the shielding plant and the fuel plant of the nuclear power station. In the construction process, the first layer of the nuclear power station structure can be constructed on the ground first, and the first layer structure becomes the completed layer after being constructed. Then, the plurality of support assemblies can be installed on the circumferential side of the completed layer. In the process of installing the support assemblies, the connecting members and the fixing members can be connected with each other by means of a crane, a hoist or other mechanical equipment, so that the support assemblies are fixed to the circumferential side of the completed layer.

The annular support platform can provide support for the construction personnel and facilitate the construction personnel to perform welding splicing work on the next layer of the nuclear power station structure, such as the second layer of the nuclear power station structure. Since the annular support platform is formed only by installing the plurality of support assemblies on the circumferential side of the completed layer, it is not necessary to erect a large number of steel pipes to form a scaffold. Therefore, compared with the prior art, the support device for nuclear power station structure construction effectively simplifies the construction steps and effectively reduces the application of manpower and material resources, thereby improving the construction efficiency. In addition, since the connecting members on the support assemblies are detachably connected with the fixing members, it is not necessary to sequentially disassemble a large number of steel pipes when disassembling the support device for nuclear power station structure construction. Only the connecting members and the fixing members need to be separated. Compared with the prior art, the support device for nuclear power station structure construction can also effectively simplify the disassembly steps, effectively reduce the application of manpower and material resources, and improve the construction efficiency.

When disassembling, only the connecting members and the fixing members need to be separated, without the need to disassemble a large number of steel pipes, thereby effectively saving manpower and material resources and improving the construction efficiency.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Example:

[0031] like Figures 1-5 As shown, the support device for nuclear power plant structure construction provided in this embodiment includes multiple support components 1 and multiple fasteners 2; the multiple fasteners 2 are used to be fixed at intervals along the circumferential sidewall of the completed construction layer 3 of the nuclear power plant structure; each support component 1 is provided with a connector 10 on one side, and the multiple connectors 10 are used to be detachably connected to the multiple fasteners 2 in a one-to-one correspondence, so that the multiple support components 1 are distributed sequentially along the circumferential side of the completed construction layer 3 and spliced ​​together to form a ring-shaped support platform.

[0032] This support device for nuclear power plant structure construction is used in the assembly and welding process of structures such as the steel containment building, shielding building, and fuel building. During construction, the overall nuclear power plant structure can be divided into multiple layers from bottom to top. The first layer of the nuclear power plant structure is then constructed on the ground. After the first layer is completed, it becomes the completed layer 3. Subsequently, multiple support components 1 can be installed around the perimeter of the completed layer 3. It should be noted that each layer of the nuclear power plant structure becomes the completed layer 3 after its completion. During the installation of the support components 1, mechanical equipment such as cranes and hoists can be used to connect the connectors 10 and the fasteners 2, thereby fixing the support components 1 to the perimeter of the completed layer 3.

[0033] After multiple support components 1 are fixed to the periphery of the completed layer 3 in sequence, the multiple support components 1 can be spliced ​​together to form a ring support platform around the periphery of the completed layer 3. This ring support platform can provide support for construction personnel, making it easier for them to perform welding and splicing operations on the next layer of nuclear power plant structure, such as the second layer of nuclear power plant structure.

[0034] Since the formation of the ring support platform only requires the installation of multiple support components 1 on the three sides of the completed construction layer, without the need to build a large number of steel pipes to form scaffolding, the support device for nuclear power plant structure construction provided in this embodiment effectively simplifies the construction steps and effectively reduces the application of manpower and material resources compared with the prior art, thereby improving construction efficiency.

[0035] In addition, since the connecting piece 10 on the support assembly 1 is detachably connected with the fixing piece 2, when the support device for nuclear power station structure construction is disassembled, a large number of steel pipes do not need to be disassembled one by one, only the connecting piece 10 and the fixing piece 2 need to be separated, compared with the prior art, the support device for nuclear power station structure construction provided by the embodiment can also effectively simplify the disassembly steps, also effectively reduce the application of manpower and material resources, and improve the construction efficiency.

[0036] It should be noted that when the construction of the nuclear power station structure above the second layer, for example, the third layer of the nuclear power station structure, is carried out, the plurality of support assemblies 1 on the periphery of the first layer of the nuclear power station structure can also be disassembled and transported and installed on the periphery of the second layer of the nuclear power station structure, thereby recycling the support assemblies 1, greatly improving the reusability of the support device for nuclear power station structure construction, and further saving the construction cost.

[0037] It should be further noted that the fixing piece 2 in the support device for nuclear power station structure construction provided by the embodiment can be pre-fixed on each assembled module of the nuclear power station structure by welding, integral molding or the like, and when any layer of the nuclear power station structure is constructed, the periphery of the constructed layer 3 is fixed with a plurality of fixing pieces 2. On this basis, a plurality of support assemblies 1 can be fixed to one side of the assembled module by the connecting piece 10 and the fixing piece 2 before the assembled module of the nuclear power station structure is transported, and when the assembled module is transported in place and the assembled modules are welded to form the constructed layer 3, the periphery of the constructed layer 3 forms an annular support platform. This construction method not only enables the connection process between the support assembly 1 and the constructed layer 3 to be carried out on the ground, but also enables the support assembly 1 to support the assembled module during transportation, which helps to enhance the strength and stiffness of the assembled module, thereby reducing the risk of deformation, instability or structural damage of the assembled module during transportation.

[0038] Compared with the prior art, the support device for nuclear power station structure construction provided by the embodiment can build a support platform on the periphery of the constructed layer 3 of the nuclear power station structure by connecting the connecting piece 10 on the plurality of support assemblies 1 with the plurality of fixing pieces 2, thereby facilitating the welding construction of the next layer of the nuclear power station structure, and when disassembled, only the connecting piece 10 and the fixing piece 2 need to be separated, without the need to disassemble a large number of steel pipes, thereby effectively saving manpower and material resources and improving construction efficiency.

[0039] In actual application, each support assembly 1 can be managed by coding, thereby facilitating inventory management and logistics distribution of the support device for nuclear power station structure construction, and the disassembly and transportation process of the support assembly 1 can also adopt a standardized process, thereby further improving construction efficiency and reducing construction cost.

[0040] For example, Figure 2 andFigure 3 As shown, the support assembly 1 includes a walking plate 11 and a support frame 12. The walking plate 11 is fixed on the support frame 12, and the side of the support frame 12 closest to the completed layer 3 can abut against the outer wall of the completed layer 3.

[0041] The walking platform 11 provides support for construction workers and serves as their work area. The support frame 12 provides a solid foundation for the walking platform 11, effectively ensuring its stability.

[0042] The side of the support frame 12 closest to the completed layer 3 can abut against the outer wall of the completed layer 3, which can increase the contact points between the support device for the construction of the nuclear power plant structure and the completed layer 3 of the nuclear power plant structure, thereby improving the installation stability of the support device for the construction of the nuclear power plant structure.

[0043] Furthermore, such as Figure 3 As shown, there can be multiple support frames 12, and the multiple support frames 12 are fixed at intervals below the walking plate 11 along the length direction of the walking plate 11.

[0044] Multiple support frames 12 can further improve the stability of the walking board 11, thereby effectively ensuring the safety of construction workers.

[0045] The support frame 12 and the walking plate 11 can be fixedly connected by fasteners such as bolts 13.

[0046] Furthermore, there can be one or more walking plates 11. For example... Figure 2 As shown, when there are multiple walking slabs 11, the multiple walking slabs 11 can be distributed sequentially along the circumference of the completed layer 3 and spliced ​​together in pairs.

[0047] like Figure 3 and Figure 4 As shown, the support frame 12 in this embodiment may include a horizontal bar 120, a vertical bar 121, and a diagonal bar 122; the horizontal bar 120, vertical bar 121, and diagonal bar 122 are connected in sequence to form a right-angled triangular structure. The horizontal bar 120 is fixed below the walking plate 11, and the vertical bar 121 stands upright on one side of the completed layer 3. This arrangement not only effectively improves the structural stability of the support frame 12 but also reduces its weight. Thus, while effectively improving the overall structural stability of the support device for nuclear power plant structure construction, it also effectively reduces the overall weight and material consumption of the support device for nuclear power plant structure construction.

[0048] In this embodiment, the horizontal bar 120, vertical bar 121 and diagonal bar 122 of the support frame 12 can all be made of angle steel.

[0049] like Figure 2 and Figure 4As shown, the connecting piece 10 is fixed to the side of the support frame 12 close to the completed construction layer 3, and the side of the support frame 12 close to the completed construction layer 3 is provided with a protrusion 123, which is lower than the connecting piece 10. The protrusion 123 is used to abut the circumferential side wall of the completed construction layer 3.

[0050] The protrusion 123 lower than the connecting piece 10 can cooperate with the connecting piece 10, so that the support assembly 1 has two contact points with the completed construction layer 3. When the construction personnel work on the walking plate 11, the contact point between the protrusion 123 and the completed construction layer 3 can provide a supporting reaction force to effectively improve the balance of the support assembly 1.

[0051] In order to ensure the use effect of the protrusion 123, the vertical distance between the side of the protrusion 123 connected to the support frame 12 and the side in contact with the completed construction layer 3 can be 50 mm.

[0052] Further, the support device for nuclear power plant structure construction provided by the embodiment further comprises a rubber cap, which is arranged outside the protrusion 123.

[0053] The rubber cap has good elasticity and wear resistance, can effectively absorb impact force, and reduce damage to the protrusion 123 and the completed construction layer 3 caused by collision or friction. At the same time, the rubber cap can also play a role in preventing slipping, thereby improving the walking safety of the construction personnel on the walking plate 11, and avoiding accidents caused by the construction personnel slipping. In addition, the rubber cap can also isolate the protrusion 123 and the completed construction layer 3, preventing the protrusion 123 from scratching the paint on the surface of the steel containment vessel, the shielding plant, the fuel plant and other nuclear power plant structures.

[0054] In order to further improve the support effect of the right-angled triangular support frame 12 on the walking plate 11, as shown in Figure 2 The top end of the vertical rod 121 in the support frame 12 can be higher than the walking plate 11, and the connecting piece 10 is fixed to the top end of the vertical rod 121. At this time, the vertical rod 121 can support the connecting piece 10, so that the connecting piece 10 is higher than the walking plate 11, and in cooperation with the protrusion 123, the triangular support stability of the support frame 12 on the walking plate 11 can be effectively improved, preventing the walking plate 11 from overturning.

[0055] As shown in Figure 2 and Figure 6 The support device for nuclear power plant structure construction provided by the embodiment further comprises a supplementary plate 4, which is arranged at the gap between any group of two adjacent support assemblies 1.

[0056] The supplementary plate 4 can ensure the close connection between the two adjacent support assemblies 1, and reduce the safety hazards during construction work.

[0057] In use, the supplementary plate 4 can be arranged between two adjacent support assemblies 1 by overlapping. In order to improve the installation stability of the supplementary plate 4, the supplementary plate 4 is preferably hinged on one side with the support assembly 1 adjacent thereto, and the other side of the supplementary plate 4 is overlapped on the support assembly 1 adjacent thereto.

[0058] The hinged connection can make one side of the support assembly 1 of the supplementary plate 4 flexible to turn over, so as to facilitate folding the supplementary plate 4 to one side of the support assembly 1 during transportation, reduce the size of the support device for nuclear power plant structure construction, and facilitate turning over the supplementary plate 4 to be flush with the support assembly 1 to cover the gap between the two adjacent support assemblies 1 during installation.

[0059] Further, the supplementary plate 4 and the support assembly 1 can be connected to each other through a hinged structure. As shown in Figure 2 and Figure 6 , the hinged structure includes a hinged pipe 5 and a hinged rod 6, the hinged rod 6 is an L-shaped rod formed by the vertical connection of a first rod and a second rod; the hinged pipe 5 is fixed on the support assembly 1 and extends along the width direction of the support assembly 1, the first rod of the hinged rod 6 is sleeved in the hinged pipe 5, and the second rod is fixedly connected with the supplementary plate 4. Among them, the second rod is located on the upper surface of the supplementary plate 4, and the hinged pipe 5 is located on the upper surface of the support assembly 1, at this time, the supplementary plate 4 can be flexibly turned over by 180 degrees, so as to realize the state that the supplementary plate 4 is folded above the support assembly 1 and flush with the support assembly 1.

[0060] In actual application, the structure of the fixing member 2 has multiple choices, the fixing member 2 can be a bolt, a buckle, etc., and correspondingly, the connecting member 10 can be a nut, a clamping hole, etc. In order to improve the installation convenience of the support assembly 1, as shown in Figure 2 , Figure 4 and Figure 5 , the embodiment preferably adopts a hanging ring as the fixing member 2 and a hook with the opening downward as the connecting member 10.

[0061] When the fixing member 2 is a hanging ring and the connecting member 10 is a hook with the opening downward, the process of installing the support assembly 1 can be achieved by hoisting the support assembly 1 on one side of the construction completed layer 3, and then moving the support assembly 1 vertically from top to bottom until the hook is hooked with the hanging ring. Correspondingly, when the support assembly 1 is disassembled, the hook and the hanging ring can be separated by moving the support assembly 1 vertically from bottom to top.

[0062] Among them, the hanging ring can be made of channel steel. Since the nuclear power plant structure is usually made of steel, the hanging ring can be formed by welding the channel steel on the circumferential side wall of the nuclear power plant structure.

[0063] To further improve the connection stability between the support assembly 1 and the nuclear power plant structure, threaded holes can be provided on the hanging ring and the hook, and the threaded holes on the hanging ring and the threaded holes on the hook are correspondingly communicated. When the hook is hooked with the hanging ring, the bolts are screwed into the threaded holes on the hanging ring and the threaded holes on the hook, so that the hook and the hanging ring are further combined together stably, thereby ensuring that the support assembly 1 can be stably hung on the circumferential side wall of the nuclear power plant structure, effectively preventing the support assembly 1 from loosening, and significantly improving the safety performance of the support assembly 1.

[0064] When the connecting piece 10 is a hook with the opening downward, in order to facilitate hoisting the support assembly 1 to hook the hook with the hanging ring, as shown in Figure 2 and Figure 7 , the embodiment preferably provides a lifting hook 7 on the support assembly 1, which is used to connect with the lifting rope 70 on the crane, hoist, or other mechanical equipment.

[0065] Among them, the shape of the lifting hook 7 has multiple choices, such as circular, square. In order to improve the stability of the hoisting process, the embodiment preferably provides a square lifting hook 7.

[0066] Further, as shown in Figure 7 , the lifting hook 7 can be provided as four, and the four lifting hooks 7 are divided into two groups, and the two groups of lifting hooks 7 are respectively arranged at the positions close to the two ends of the support assembly 1, and the two lifting hooks 7 in each group of lifting hooks 7 are spaced apart along the width direction of the support assembly 1. At this time, the four lifting hooks 7 are installed at the four corner portions close to the support assembly 1 and are symmetrically distributed on the support assembly 1, which can effectively improve the balance and stability of the support assembly 1 during hoisting.

[0067] When the support assembly 1 includes the walking plate 11 and the support frame 12, as shown in Figure 2 , the walking plate 11 can be provided with two installation holes spaced apart, and as shown in Figure 3 , the lifting hook 7 can be formed by a bent rod member which is sequentially threaded through one of the installation holes, the cross rod 120 of the support frame 12, and the other installation hole and then connected end to end. At this time, the lifting hook 7 can not only be connected with the lifting rope 70 of the hoisting equipment during hoisting the support assembly 1, but also will automatically fall and tightly adhere to the surface of the walking plate 11 after hoisting is completed, thereby avoiding affecting the walking process of the construction personnel on the walking plate 11.

[0068] Further, as shown in Figure 1 and Figure 2 , the support device for nuclear power plant structure construction provided by the embodiment further includes a guardrail assembly 8, and each support assembly 1 is fixed with a guardrail assembly 8 away from the construction completed layer 3.

[0069] The guardrail assembly 8 can play a protective role and effectively prevent the construction personnel from falling from a high place.

[0070] In this embodiment, the guardrail assembly 8 can be composed of railings and protective netting, and the bottom of the guardrail assembly 8 can be provided with a kick plate 80.

[0071] Guardrails can further enhance construction safety, while kickboards can effectively prevent tools or other objects from falling from heights, avoiding personal injury or equipment damage.

[0072] like Figure 1 As shown, the support device for nuclear power plant structure construction provided in this embodiment also includes a reinforcement structure 9, and the guardrail components 8 on any two adjacent support components 1 are detachably connected to the reinforcement structure 9.

[0073] The reinforcement structure 9 can connect the guardrail components 8 on two adjacent support components 1, thereby improving the stability and protective effect of the guardrail components 8.

[0074] Among them, the reinforcement structure 9 can adopt structures such as ropes and reinforcement plates. There are no restrictions on its structure, as long as it can achieve the connection and fixation between the guardrail components 8.

[0075] like Figure 1 As shown, the preferred reinforcement structure 9 in this embodiment includes a clamp 90 and a connecting pipe 91. The connecting pipe 91 is vertically arranged between the vertical members of two adjacent guardrail components 8, and the clamp 90 is used to fix the connecting pipe 91 and the adjacent vertical member.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
