A porous composite shear wall structure and method suitable for nuclear power plants

Abstract

This application provides a porous composite shear wall structure and its construction and design methods. The construction method includes: configuring a precast concrete wall with multiple pre-reserved holes, providing multiple optional installation positions for embedded parts; after selecting the installation position of the embedded part, installing the embedded part into the corresponding pre-reserved hole; sealing the connection between the embedded part and the precast concrete wall, as well as the remaining pre-reserved holes, and then pouring cast-in-place concrete. The porous composite shear wall structure provided by this application provides multiple optional installation positions by setting multiple pre-reserved holes, allowing the installation scheme of the embedded parts to be determined before on-site pouring. This allows the production of precast components to precede the determination of the embedded part installation scheme, avoiding the inability to adjust the arrangement of embedded parts after precasting. Sealing the connection between the embedded part and the precast concrete wall, as well as the remaining pre-reserved holes, effectively avoids grout leakage problems during subsequent concrete pouring.

Description

Technical Field

[0001] This application relates to the field of shear wall technology, specifically to a porous composite shear wall structure and method suitable for nuclear power plants. Background Technology

[0002] Currently, most third-generation nuclear power plant buildings employ thick shear wall structures, and construction often involves on-site rebar binding or the use of partial rebar cages, resulting in a large volume of on-site formwork work and low efficiency. Prefabricated shear wall structures are suitable for nuclear power plant applications, but if a prefabricated shear wall structure is used as a whole, the lifting weight is large, requiring sophisticated lifting equipment, and the wall placement is difficult. While composite shear wall structures can alleviate the lifting pressure, the following technical problems still exist: In nuclear power engineering, shear wall structures typically require a large number of embedded parts, and the arrangement of these embedded parts often changes during design optimization and modification. If the production of prefabricated components for the shear wall structure precedes the determination of the embedded part arrangement, the arrangement of the embedded parts cannot be adjusted after the prefabricated components are manufactured. This becomes a key obstacle to the implementation of prefabricated shear wall structures in nuclear power plant projects.

[0003] Furthermore, composite shear wall structures also suffer from problems such as complex construction of panel wall joints, easy damage to the reinforcing steel bars of the wall by newly added embedded parts, and easy leakage of grout during the pouring process, making it difficult to meet the dual requirements of structural safety and construction flexibility in nuclear power engineering.

[0004] In view of this, this application proposes a porous composite shear wall structure suitable for nuclear power plants and its construction method, in order to solve one or a combination of the above-mentioned technical problems. Summary of the Invention

[0005] The first aspect of this application is to provide a construction method for porous composite shear wall structures suitable for nuclear power plants.

[0006] The second aspect of this application is to provide a porous composite shear wall structure suitable for nuclear power plants.

[0007] A third aspect of this application is to provide a design method for porous composite shear wall structures suitable for nuclear power plants.

[0008] The construction method for porous composite shear wall structures applicable to nuclear power plants according to the first aspect of this application includes the following steps: Providing prefabricated components for the porous composite shear wall structure includes: configuring a prefabricated concrete wall with a plurality of reserved holes, wherein the plurality of reserved holes can provide a plurality of optional installation positions for installing embedded parts; After the installation position of the embedded part is selected, the embedded part is installed into the corresponding reserved hole; After sealing the connection between the embedded part and the precast concrete wall, and sealing the remaining reserved holes not used for installing the embedded part, concrete is then poured on site to obtain the porous composite shear wall structure.

[0009] The composite shear wall structure construction method provided in this application uses precast concrete walls as casting templates, reducing on-site formwork work compared to the traditional method of casting shear walls as a whole. Compared to the fully precast shear wall scheme, the composite structure helps reduce hoisting weight and lowers on-site construction difficulty. Multiple pre-reserved holes in the precast concrete walls provide multiple optional installation positions, allowing the embedded part installation scheme to be determined before on-site pouring, reserving sufficient time for design changes, and allowing precast component production to precede the embedded part scheme determination. This avoids the problem of unadjustable embedded part placement after precasting, shortening the construction period and reducing waste, especially suitable for the frequent changes in embedded part schemes in nuclear power projects. Sealing the connection points between the embedded parts and the precast concrete walls, as well as sealing the remaining pre-reserved holes not used for installing embedded parts, effectively prevents cement slurry leakage during cast-in-place concrete pouring due to the pre-reserved holes and embedded part installation, ensuring construction quality.

[0010] In some embodiments, the remaining reserved holes are sealed by cooperating with a threaded sleeve disposed in the reserved hole using a sealing bolt.

[0011] In some embodiments, after the embedded part is installed into the corresponding reserved hole, the edge position where the embedded part contacts the precast concrete wall is sealed by a sealing structure to achieve the sealing of the connection position between the embedded part and the precast concrete wall.

[0012] In some embodiments, the precast concrete wall is configured such that a plurality of the reserved holes are evenly arranged, and the spacing between the anchoring parts of the embedded part is adapted to the spacing between adjacent reserved holes, so that the plurality of anchoring parts of the embedded part can be correspondingly inserted into the plurality of reserved holes.

[0013] In some embodiments, the precast concrete wall is configured to have a plurality of pre-reserved holes arranged in a matrix, wherein the spacing between the anchorages of the plurality of different embedded parts is adapted to the spacing between adjacent pre-reserved holes.

[0014] In some embodiments, the prefabricated components of the porous composite shear wall structure further include: pre-embedding steel sleeves at the slab-wall connection points of the prefabricated concrete wall, wherein the steel sleeves are used to provide anchorage and fixing positions for the longitudinal steel bars of the floor slab.

[0015] In some embodiments, after obtaining the porous composite shear wall structure, holes are drilled at the positions corresponding to the reserved holes to provide installation positions for the post-embedded parts.

[0016] In some embodiments, providing prefabricated components of the porous composite shear wall structure further includes: configuring the prefabricated concrete wall to include two layers of prefabricated walls and having a steel reinforcement frame.

[0017] According to the second aspect of this application, a porous composite shear wall structure is used to perform the construction method as described in the first aspect, comprising a precast concrete wall, embedded parts, and a sealing structure; wherein the precast concrete wall has a plurality of reserved holes, the plurality of reserved holes providing a plurality of optional installation positions for installing the embedded parts; the embedded parts are installed in the reserved holes; the sealing structure includes a first sealing structure and a second sealing structure, the first sealing structure sealing the connection position between the embedded parts and the precast concrete wall, and the second sealing structure sealing the remaining reserved holes where the embedded parts are not installed.

[0018] The design method for a porous composite shear wall structure according to the third aspect of this application, used to realize the design of a porous composite shear wall structure as described in the first aspect, includes the following steps: Designing a precast concrete wall includes: designing a plurality of reserved holes in the precast concrete wall, such that the plurality of reserved holes provide a plurality of optional installation positions for installing embedded parts; The embedded parts are designed such that the spacing between the anchoring parts of the embedded parts is adapted to the spacing between the adjacent reserved holes; Design a sealing structure for the connection between the embedded part and the precast concrete wall, and design a sealing structure for the remaining reserved holes where the embedded part is not installed.

[0031] This application uses flowcharts to illustrate the operations performed according to embodiments of this application. It should be understood that, depending on the actual situation, the steps shown in the diagrams are not necessarily performed sequentially, and other operations may be added to these processes, or one or more steps may be removed from these processes.

[0032] It is understood that the porous composite shear wall structure and its construction and design methods provided in this application are particularly suitable for scenarios where the installation scheme of embedded parts in nuclear power engineering needs to be frequently changed. They can also be applied to other applicable occasions, and are not limited thereto.

[0033] See Figures 1 to 5 The diagram shows a porous composite shear wall structure 1 suitable for nuclear power plants and its construction method. The construction method includes the following steps: S1. Factory prefabrication steps: A prefabricated component for a porous composite shear wall structure 1 is provided, comprising: providing a prefabricated component for a composite shear wall, and configuring its prefabricated concrete wall 13 to have a plurality of reserved holes 11, the plurality of reserved holes 11 being able to provide a plurality of optional installation positions for installing embedded parts 121.

[0034] The reserved holes 11 mentioned here are prefabricated holes for the anchoring parts 123 (such as anchor bars, anchor bolts, etc.) of the embedded parts 12 (embedded parts 121 and post-installed embedded parts 122) to pass through for anchoring and fixing. When installing the embedded parts 121, their anchor bars pass through the corresponding reserved holes 11 and achieve a reliable connection through grouting.

[0035] Compared to the traditional construction method of cast-in-place shear walls, the use of prefabricated shear wall structures can effectively reduce the amount of on-site formwork. Compared to the fully precast shear wall scheme (i.e., the entire steel-concrete structure of the wall is prefabricated in the factory), the use of composite shear wall structures, with precast concrete wall 13 as the on-site casting formwork, helps to reduce the weight of precast components during hoisting and reduces the difficulty of on-site construction.

[0036] S2. Installation steps for embedded parts: After the installation position of the embedded part 121 is selected, the embedded part 121 is installed into the reserved hole 11 corresponding to the installation position.

[0037] By setting multiple reserved holes 11 to provide multiple optional installation positions, the installation position of the embedded part 121 can be delayed until before on-site pouring, allowing sufficient adjustment time for design changes, and allowing the production of precast components of the multi-hole composite shear wall structure 1 to be earlier than the determination of the installation plan of the embedded part 121, avoiding the technical problem that the layout plan of the embedded part 121 cannot be adjusted after the precast components are manufactured, which helps to shorten the construction period and reduce waste.

[0038] S3. Sealing and on-site pouring steps: The connection between the embedded part 121 and the precast concrete wall 13 is sealed, and the remaining reserved holes 11 not used for installing the embedded part 121 are sealed. Then, concrete is poured on the construction site to obtain the porous composite shear wall structure 1.

[0039] The connection between the sealed embedded part 121 and the precast concrete wall 13, as well as the unused reserved holes 11, can effectively prevent the cement slurry from flowing out during the subsequent concrete pouring process due to the setting of reserved holes 11 and the installation of embedded parts 121, thus ensuring the construction quality.

[0040] like Figure 3 As shown, in some embodiments, after the embedded part 121 is installed into the corresponding reserved hole 11, a sealing structure, such as applying sealant or setting a sealing strip, is used to seal the edge position (contact gap) where the embedded part 121 contacts the precast concrete wall 13, so as to seal the connection position between the embedded part 121 and the precast concrete wall 13, effectively preventing the grout from seeping out from the edge position during the pouring process, simplifying the construction, and ensuring a reliable connection between the embedded part 121 and the precast concrete wall 13.

[0041] like Figure 4 As shown, in some embodiments, the remaining reserved holes 11 not used for installing the embedded part 121 are sealed by the cooperation of the sealing bolt 171 with the threaded sleeve 172 provided in the reserved hole 11. The sealing bolt 171 mentioned here is a threaded connector with an integrated sealing structure.

[0042] Generally, the threaded sleeve 172 can be installed in the pre-drilled hole 11 during the factory prefabrication process. Therefore, during on-site construction, only the sealing bolt 171 needs to be screwed into the pre-drilled hole 11 not used for installing the pre-drilled part 121 after the layout of the embedded part 121 is determined, thus sealing the remaining pre-drilled holes 11. The operation is simple. Using the sealing bolt 171 and threaded sleeve 172 also facilitates the provision of pre-tightening force through the threaded engagement to ensure connection strength and withstand the pressure applied during grouting.

[0043] like Figure 1As shown, in some embodiments, the precast concrete wall 13 is configured such that multiple reserved holes 11 are evenly arranged, and the spacing of adjacent anchoring parts 123 of the embedded parts 12 (pre-embedded parts 121 and post-embedded parts 122) is adapted to the spacing of adjacent reserved holes 11, for example, the two are equal or an integer multiple, so that multiple anchoring parts 123 of the embedded parts 12 can be inserted into multiple reserved holes 11 accordingly. This is beneficial to improve the flexibility of the design change of the installation position of the embedded parts 12 and make fuller use of the reserved holes 11 and the wall surface.

[0044] Furthermore, the precast concrete wall 13 is configured to have a plurality of pre-reserved holes 11 arranged in a matrix; in other words, the plurality of pre-reserved holes 11 are evenly arranged at fixed intervals along both the transverse and longitudinal directions of the wall surface (e.g., Figure 1 As shown), the spacing between adjacent anchoring portions 123 of multiple different embedded parts 12 is adapted to the spacing between adjacent reserved holes 11. For example, at least the first embedded part 1211 and the second embedded part 1212 are adapted to the reserved holes 11.

[0045] This provides a standardized connection structure between the wall and the embedded part 12, allowing a single reserved hole 11 to be used in more installation locations and reused by different embedded parts 12, further improving the utilization rate of the reserved hole 11 and the wall surface, as well as the flexibility of the embedded part 12. It can be understood that the layout scheme of the reserved hole 11 can also be determined according to the standardized embedded part 12 specifications commonly used in the nuclear power field, so as to promote its application in nuclear power engineering.

[0046] like Figure 2 As shown, in some embodiments, the prefabricated components of the porous composite shear wall structure 1 further include: pre-embedded steel sleeves 141 at the wall-slab connection portion 14 of the prefabricated concrete wall 13. The steel sleeves 141 are used to provide anchorage positions for the longitudinal steel bars 142 of the floor slab. The wall-slab connection portion 14 mentioned here refers to the interface area between the prefabricated concrete wall 13 and the horizontal floor slab. The steel sleeves 141 pre-embedded in the prefabrication process facilitate the anchorage of the longitudinal steel bars 152 of the floor slab. After the wall is hoisted on site, the longitudinal steel bars 152 of the floor slab can be screwed into the steel sleeves 141, achieving a rapid connection without on-site formwork.

[0047] like Figure 2 As shown, in some embodiments, the prefabricated components of the porous composite shear wall structure 1 further include: the prefabricated concrete wall 13 adopts a double-layer prefabricated wall structure, with a steel reinforcement skeleton 15 inside, to ensure that the mechanical properties of the porous composite shear wall meet the safety requirements of nuclear power engineering, and a space is provided between the two layers of walls for pouring cast-in-place concrete.

[0048] Generally, the double-layer precast wall and the steel reinforcement frame 15 can adopt a common arrangement in the field. For example, the steel reinforcement frame 15 includes transverse steel bars 151, longitudinal steel bars 152, and truss bars 153 connecting the two layers of precast walls arranged in the double-layer precast wall, which will not be elaborated here. When arranging the steel reinforcement frame 15, care should also be taken to avoid leaving the internal space reserved for the anchorage of the embedded part 121.

[0049] When tying the reinforcing steel cage 15, longitudinal reinforcing steel bars 142 and related mechanical connectors for the floor slab can be pre-embedded at the wall-slab connection points 14. The pre-embedded longitudinal reinforcing steel bars 142 can also be used in conjunction with the aforementioned reinforcing steel sleeves 141. After the reinforcing steel bars are tied, precast concrete is poured to form the structure. In this way, the reinforcing steel bars for the wall-slab connection nodes are pre-embedded in the factory, eliminating the need for formwork and tying of node reinforcing steel bars on site. This simplifies construction and is particularly suitable for the simultaneous installation of precast floor slabs, enabling the construction of a complete prefabricated building system for nuclear power plants.

[0050] like Figure 1 , Figure 5 As shown, in some embodiments, the construction method further includes: S4. Installation steps for rear-mounted embedded part 122: After obtaining the porous composite shear wall structure 1, holes are drilled at the positions corresponding to the reserved holes 11 to provide installation positions for the post-installed embedded parts 122. In other words, after the cast-in-place concrete layer of the porous composite shear wall structure 1 is poured and the wall is shaped, if it is necessary to install the post-installed embedded parts 122, holes can be drilled directly at the positions corresponding to the reserved holes 11 to avoid the steel reinforcement skeleton 15 inside the wall. This eliminates concerns about damaging the reinforcing steel, does not affect the structural safety of the wall, and simplifies construction.

[0051] In one example, the construction method of the porous composite shear wall structure 1 specifically includes: S101. A prefabricated component for a multi-hole composite shear wall 1 prefabricated in a factory, comprising: a two-layer prefabricated wall structure and a steel reinforcement skeleton 15 for providing a prefabricated concrete wall 13; threaded sleeves 172 positioned and installed in a matrix arrangement; longitudinal steel reinforcement and connectors of the floor slab pre-embedded at the junction of the wall panels; and concrete poured in the factory (i.e., the prefabrication site, not the final construction site) after the steel reinforcement is tied to obtain the prefabricated concrete wall 13. S201. Hoist the precast concrete wall 13 to the predetermined position on site (i.e. the final construction site). After the layout plan of the embedded part 121 is determined, insert the anchor bar of the embedded part 121 into the corresponding reserved hole. At the junction of the wall panel and the precast floor slab, use dry connection or wet joint connection. S301. After the embedded part 121 is installed in place, a sealing structure is set at the contact gap between the periphery of the embedded part 121 and the precast concrete wall 13, and sealing bolts 171 are provided to be screwed into the remaining reserved holes not used for installing the embedded part 121. Then, concrete is poured on site to shape the entire porous composite shear wall structure 1 and complete the wall construction.

[0052] like Figures 1 to 4 As shown, this application also provides a porous composite shear wall structure 1, which can perform the construction method described above, including a precast concrete wall 13, embedded parts 121, and a sealing structure. The precast concrete wall 13 has multiple reserved holes 11, providing multiple optional installation positions for the embedded parts 121; the embedded parts 121 are installed in the reserved holes 11; the sealing structure includes a first sealing structure 16 and a second sealing structure 17, the first sealing structure 16 sealing the connection position between the embedded parts 121 and the precast concrete wall 13, and the second sealing structure 17 sealing the remaining reserved holes 11 where the embedded parts 121 are not installed.

[0053] The first sealing structure 16 is, for example, the sealant and sealing strip provided in the contact gap between the embedded part 121 and the precast concrete wall 13 as described above; the second sealing structure 17 includes, for example, the sealing bolt 171 and threaded sleeve 172 connected as described above, which will not be described in detail here.

[0054] This application also provides a design method for a porous composite shear wall structure 1, which is used to design the porous composite shear wall structure 1, including the following steps: The design of the precast concrete wall 13 includes: designing a plurality of reserved holes 11 on the precast concrete wall 13, such that the plurality of reserved holes 11 provide a plurality of optional installation positions for installing the embedded parts 121. The embedded part 121 is designed so that the spacing between adjacent anchoring parts 123 of the embedded part 121 is adapted to the spacing between adjacent reserved holes 11. The design includes sealing structures for the connection between the embedded part 121 and the precast concrete wall 13, as well as sealing structures for the remaining reserved holes 11 where the embedded part 121 is not installed, to prevent grout leakage during subsequent concrete pouring.

[0055] Furthermore, the design method for the porous composite shear wall structure 1 also includes: The reserved holes 11 of the precast concrete wall 13 are designed to be arranged in a matrix with fixed spacing along the horizontal and vertical directions. At the same time, the spacing of the anchoring parts of various embedded parts 12 is designed to be equal to or an integer multiple of the spacing of the adjacent reserved holes 11. This provides a standardized connection interface between the embedded parts 12 and the wall, which can adapt to the installation requirements of multiple specifications of embedded parts 12, simplify the design process and improve construction efficiency.

[0056] In summary, the beneficial technical effects of this application include, but are not limited to, at least one of the following: The composite shear wall structure construction method provided in this application uses precast concrete walls as casting templates, reducing the amount of on-site formwork work compared to the traditional method of cast-in-place shear walls. The composite structure reduces hoisting weight and on-site construction difficulty compared to integral precast shear walls. Multiple pre-reserved holes in the precast concrete walls provide multiple optional installation positions, allowing the embedded part installation scheme to be determined before on-site pouring. This provides sufficient time for design changes and allows precast component production to precede the embedded part scheme determination, avoiding the problem of unadjustable embedded part placement after precasting. This shortens the construction period, reduces waste, and is particularly suitable for the frequent changes in embedded part schemes required in nuclear power projects. Sealing the connection points between the embedded parts and the precast concrete walls, as well as sealing the remaining pre-reserved holes not used for installing embedded parts, effectively prevents cement slurry leakage during cast-in-place concrete pouring due to the pre-reserved holes and embedded part installation, thus ensuring construction quality.

[0057] While this application discloses preferred embodiments as described above, it is not intended to limit the scope of this application. Any changes and modifications can be made by those skilled in the art without departing from the spirit and scope of this application. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall fall within the protection scope defined by the claims of this application.
