Description

Technical Field

[0001] The invention specifically relates to a wall panel module of a steel plate concrete wall, a nuclear industrial plant and a manufacturing method. Background Art

[0002] At present, the nuclear power industry has entered a safe and efficient development period. Nuclear power owners and construction units have put forward higher requirements and goals for project quality, construction period, project cost, etc. However, the traditional construction and installation methods are restricted by construction logic, and the space for optimizing the construction period is very limited; the development of advanced construction technology, construction methods, and the change of traditional construction and installation processes in terms of resource occupation can also achieve the purpose of improving project quality, reducing safety hazards, and shortening construction period.

[0003] Nowadays, modular technology plays a significant role in improving construction quality, shortening construction period, reducing manpower input and improving efficiency. In modular technology, steel plate concrete composite wall structure can usually be used as floor slabs and walls. Compared with ordinary reinforced concrete structures, it has the following advantages: the combined force of steel plate and concrete can significantly improve the bearing capacity, ductility and impact and explosion resistance of components; steel plate has isotropic tensile strength and is suitable for special-shaped irregular components; steel plate can also serve as concrete formwork to simplify the on-site formwork process.

[0004] However, in the nuclear power field, such as nuclear island plants, the walls of the plants often need to have a large number of holes for cables, pipes and other pipeline structures to pass through. The steel plate concrete composite wall structure is very difficult to dismantle and modify. When used in nuclear power plants, leaving these holes usually requires a lot of adjustments and modifications to the original walls. These modifications not only require a lot of manpower and time, but may also cause problems such as reduced wall strength. Summary of the invention

[0005] The inventors of the present invention have found that it is currently difficult to dismantle and modify a completed steel plate concrete composite wall structure because, for a double steel plate steel plate concrete composite wall structure, reinforcement bars are usually provided between the steel plates on both sides of the wall panel module (i.e., the part where concrete is not poured). Figure 1 and Figure 2 As shown in the figure, the tie bars are connected to the steel plates on both sides by plug welding. The tie bars are used to connect the steel plates on both sides so that they can resist construction loads such as hoisting and pouring; at the same time, they are used to bear the out-of-plane shear force generated by various loads during the use stage. Once the holes are opened, dismantled and modified, the original tie bar layout inside the wall panel module needs to be changed, which will destroy the structural balance of the wall panel module and make it difficult for the wall panel module to achieve the original structural strength.

[0006] The technical problem to be solved by the present invention is to provide a wall panel module of a steel plate concrete wall in view of the above-mentioned deficiencies in the prior art. The wall panel module has a simple structure and a reasonable layout, and can provide a path for pipelines passing through the wall without destroying the original structural balance, thereby improving construction flexibility, reducing construction difficulty, and improving economic efficiency. The present invention also provides a nuclear industrial plant, a concrete unit manufacturing method, and a nuclear industrial plant manufacturing method.

[0007] The present invention provides a wall panel module of a steel plate concrete wall, comprising a wall panel, a tie rod and a sleeve, wherein a plurality of tie positions are arranged on the wall panel in a set layout manner, the wall panel comprises a first area and a second area, the second area is an area where a through-wall pipeline needs to pass through the wall panel, the tie rod is located between two relatively arranged wall panels, and the two ends of the tie rod are respectively connected to the tie positions in the first area, the sleeve is a tubular structure whose equivalent strength to the tie rod cross section satisfies a set relationship, the sleeve is located between two relatively arranged wall panels, and the two ends of the sleeve are respectively connected to the tie positions in the second area, so that the inner hole of the sleeve is used as a channel for the through-wall pipeline to pass through the wall panel.

[0008] Furthermore, the set relationship satisfied by the cross-sectional equivalent strength of the sleeve and the reinforcement is:

[0009] F y2 ·A s2 ≥F y1 ·A s1

[0010] Among them, F y1 is the material strength of the reinforcement, A s1 is the cross-sectional area of ​​the reinforcement, F y2 A is the strength of the casing material, s2 It is the cross-sectional area of ​​the casing, and the material grade of the casing is not greater than the material grade of the wall panel.

[0011] Furthermore, the outer diameter D and thickness h of the sleeve satisfy the following formula, so that the cross-sectional equivalent strength of the sleeve and the reinforcement satisfies the set relationship:

[0012]

[0013] Among them, S is the cross-sectional area required for the wall pipeline to penetrate the wall panel.

[0014] Furthermore, the setting layout of the tie-down positions is a square array layout with equal spacing in the longitudinal and transverse directions.

[0015] Furthermore, the wall panel is provided with a connection hole corresponding to each tie position for connecting a tie rod or a sleeve.

[0016] Furthermore, two ends of the tie rod are respectively welded and connected to connection holes provided at corresponding tie positions of the two wall panels.

[0017] Furthermore, two ends of the sleeve are respectively welded and connected to connection holes provided at corresponding tie positions of the two wall panels.

[0018] Furthermore, the wall panel module of the steel plate concrete wall also includes a connecting component, which includes a first gasket, a second gasket and a third gasket. The two ends of the sleeve are respectively inserted into connecting holes provided at corresponding tie positions of the two wall panels. The first gasket and the second gasket are both sleeved on one end of the sleeve, and are respectively located on the outside and inside of the connecting hole penetrated by the end of the sleeve, so as to clamp and fix the wall panel where the connecting hole is located. The third gasket is sleeved on the other end of the sleeve, and is located on the outside of the connecting hole penetrated by the other end of the sleeve, thereby clamping and fixing the two wall panels together with the first gasket.

[0019] Furthermore, the second gasket is welded to the sleeve.

[0020] Furthermore, both ends of the sleeve are provided with external threads, the inner holes of the first gasket and the third gasket are both provided with internal threads, and the first gasket and the third gasket are both fastened to the sleeve by threads.

[0021] The present invention also provides a nuclear industrial plant, the wall panels and / or floor panels of the nuclear industrial plant include concrete units, and the concrete units are formed by pouring concrete in the wall panel modules using the wall panel modules of the above-mentioned steel plate concrete wall as casting templates.

[0022] The present invention also provides a method for manufacturing a concrete unit, comprising the following steps: prefabricating a wall panel module of the steel plate concrete wall;

[0023] Lift and install the wall panel modules at the set position;

[0024] Concrete is poured in the wall panel modules to form concrete units.

[0025] Furthermore, after the wall panel module is hoisted and installed at the set position, the following steps are also included to allow the wall panel module to allow the through-wall pipeline that has temporarily changed its position to pass through: a connection hole is opened at the tie position corresponding to the through-wall pipeline on the wall panel;

[0026] Insert the two ends of the sleeve with the second gasket into the connection holes of the two wall panels respectively, so that the second gasket is pressed against the inner side of one connection hole;

[0027] Fix the first gasket on the sleeve and press against the outer side of the connecting hole corresponding to the second gasket;

[0028] Fix the third gasket on the sleeve and press it against the outside of the other connecting hole.

[0029] The present invention also provides a method for manufacturing a nuclear industrial plant, comprising the following steps: using the above-mentioned concrete unit manufacturing method to manufacture concrete units forming walls and / or floor slabs;

[0030] When laying the through-wall pipeline, the through-wall pipeline is passed through the inner hole of the sleeve of the wall panel module to enter the space on the other side of the wall and / or floor slab.

[0031] The present invention provides a wall panel module of a steel plate concrete wall, wherein a plurality of anchoring positions are preset on the wall panel of the wall panel module according to a set layout mode, and positions where through-wall pipelines need to pass through the wall panel are pre-planned, and the wall panel is divided into a first area and a second area accordingly, and reinforcement bars are connected to the anchoring positions in the first area of ​​the wall panel, and a tubular structure sleeve having an equivalent strength to the reinforcement cross-section that satisfies a set relationship is connected to the anchoring positions in the second area of ​​the wall panel, so that the inner hole of the sleeve is used as a channel for the through-wall pipeline to pass through the wall panel.

[0032] For the area where cables and small pipelines need to be laid out during the layout of this wall panel module, the original tie rods are replaced with sleeves in advance, and the equivalent strength of the structural section before and after the replacement satisfies the set relationship. This set relationship specifically ensures that the structural balance and structural strength of the wall panel before and after the replacement are not affected. The inner hole of the sleeve can also allow the pipeline to pass through the wall panel as a channel, so there is no need to dismantle and modify on site, avoiding the investment of a lot of manpower and time, and reducing the intensity and difficulty of on-site construction. And because the equivalent strength of the sleeve and the tie rod section meets the set relationship, and is arranged at the tie position arranged according to the set layout method, replacing the tie rod to achieve the tie, even if it is replaced, the layout plan inside the wall panel module is not changed, and the structural balance of the wall panel module will not be destroyed. The sleeve can also play the role of resisting the lifting and pouring construction loads and bearing the external shear force that the original tie rod can achieve, that is, the original structural strength of the wall panel module is guaranteed, so that the sleeve can solve the tooling and out-of-plane shear resistance while providing a path for cables and other items to pass through.

[0047] Example 1

[0048] like Figures 3 to 9 As shown, the wall panel module of the steel plate concrete wall of this embodiment includes a wall panel 1, a tie rod 2 and a sleeve 3. A plurality of tie positions are arranged on the wall panel 1 according to a set layout. The wall panel 1 includes a first area and a second area. The second area is an area where the through-wall pipeline needs to pass through the wall panel 1. The tie rod 2 is located between two relatively arranged wall panels 1, and the two ends of the tie rod 2 are respectively connected to the tie positions in the first area. The sleeve 3 is a tubular structure whose equivalent strength to the cross-section of the tie rod 2 satisfies a set relationship. The sleeve 3 is located between two relatively arranged wall panels 1, and the two ends of the sleeve 3 are respectively connected to the tie positions in the second area of ​​the wall panel 1, so that the inner hole of the sleeve 3 is used as a channel for the through-wall pipeline to pass through the wall panel 1.

[0049] For the area where cables and small pipelines need to be laid out during the layout of this wall panel module, the original tie rod 2 is replaced with a sleeve 3 in advance, and the equivalent strength of the structural section before and after the replacement satisfies the set relationship. This set relationship specifically ensures that the structural balance and structural strength of the wall panel 1 before and after the replacement are not affected. According to the number of tie positions in the second area, it can be replaced in groups or individually. The inner hole of the sleeve 3 can also allow the pipeline to pass through the wall panel as a channel, so there is no need to dismantle and modify on site, avoid investing a lot of manpower and time, and reduce the intensity and difficulty of on-site construction. And because the sleeve 3 and the tie rod 2 cross-sectional equivalent strength meet the set relationship, and are arranged at the tie position arranged according to the set layout mode, replacing the tie rod 2 to achieve the tie, even if it is replaced, the layout plan inside the wall panel module is not changed, and the structural balance of the wall panel module will not be destroyed. The sleeve 3 can also play the role of resisting the hoisting and pouring construction loads and bearing the external shear force that the original tie rod 2 can achieve, that is, the original structural strength of the wall panel module is guaranteed, so that the sleeve 3 can solve the tooling and out-of-plane shear resistance while providing a path for cables and other items to pass through.

[0050] In this embodiment, the set relationship between the cross-sectional equivalent strength of the sleeve 3 and the tie rod 2 is the following formula, so that the structural balance and structural strength of the wall panel 1 before and after replacement are not affected:

[0051] F y2 ·A s2 ≥F y1 ·A s1 (1)

[0052] Among them, F y1 is the material strength of the reinforcement 2, A s1 is the cross-sectional area of ​​the reinforcement 2, F y2 A is the material strength of casing 3, s2The cross-sectional area of ​​the sleeve 3 is equal to or less than the material grade of the wallboard 1. For example, when the wallboard 1 uses Q355 steel, the sleeve 3 should use Q355 or less steel. In general, it is advisable to use steel of the same material as the wallboard 1. The sleeve 3 of this embodiment can be obtained by the size and material of the tie bar 2 and the material of the required sleeve 3. Since the sleeve 3 is a hollow structure and the tie bar 2 is a solid structure, when the formula (1) is satisfied and the material grade of the sleeve 3 is not greater than the material grade of the wallboard 1, the cross-sectional equivalent strength of the tie bar 2 and the sleeve 3 can be basically consistent, and the material grade of the sleeve 3 is not greater than the material grade of the wallboard 1. This setting method can ensure the replacement of the same strength as before, and can also minimize welding problems, which is conducive to the connection of the sleeve 3 and the tie bar 2 to the wallboard 1. The material strength is the strength characteristics of the material itself (such as tensile and shear resistance, etc.), which is specifically selected according to the problems that need to be overcome in the application scenario, and will not be elaborated here.

[0053] Specifically, according to formula (1), further calculation is performed, and the outer diameter D and thickness h of the sleeve 3 satisfy the following formula, so that the cross-sectional equivalent strength of the sleeve 3 and the tie rod 2 satisfies the set relationship:

[0054]

[0055]

[0056] Wherein, S is the cross-sectional area required for the wall-penetrating pipeline to penetrate the wall panel 1, which is a set value selected according to the actual situation of the wall-penetrating pipeline and will not be elaborated here.

[0057] In this embodiment, the layout of the tie-in positions is a square array layout with equal spacing in the longitudinal and transverse directions. In this embodiment, a square array layout of 200 mm×200 mm is specifically selected.

[0058] Example 2

[0059] This embodiment includes all the configuration schemes in Embodiment 1. In addition, in this embodiment, Figure 3 and Figure 4 As shown, the wall panel 1 is provided with connection holes at each tie position corresponding to the tie rod 2 or the sleeve 3. The hole diameter of the connection hole in the first area is adapted to the diameter of the tie rod 2, and the hole diameter of the connection hole in the second area is adapted to the outer diameter of the sleeve 3. The wall panel 1 is made of steel plate, which can also serve as a concrete pouring template.

[0060] In this embodiment, the two ends of the tie rod 2 are respectively welded to the connection holes provided at the corresponding tie positions of the two wall panels 1. The welding connection can be performed by perforation plug welding.

[0061] In this embodiment, both ends of the sleeve 3 are respectively welded to the connection holes provided at the corresponding tie positions of the two wall panels 1. The sleeve 3 can be made of a steel pipe and welded in a conventional manner.

[0062] Specifically, in the wallboard module of the steel plate concrete wall of this embodiment, the arrangement method of steel pipe-reinforcement is as follows: the two sides of the structure are steel plates, and steel bars with a spacing of 200mmX200mm are arranged on the steel plates (in the first area). The local position (second area) where the cables and pipelines are passed through selects steel pipes of different diameters according to the size of the items, and steel pipes are used to replace the reinforcement in the local area. The reinforcement is welded and fixed with the steel plates on both sides by perforated plug welding, and the two ends of the steel pipe (casing 3) are connected to the steel plate by arc welding. The overall structure is complete and reliable, which is convenient for on-site construction. Traditional reinforcement is welded on the steel plate and can only be used as a structural member. In this embodiment, the steel pipe replaces the traditional steel bar and also has the function of pre-buried holes. During construction, it is directly avoided to open holes on site to damage the prefabricated module. The difficulty and construction period of laying cables and pipelines in the equipment installation stage can be greatly reduced. In this embodiment, the arrangement schemes such as steel plate thickness, reinforcement diameter and steel pipe size, length, and arrangement spacing can be determined by structural modeling software analysis and calculation.

[0063] In general, the wall panel module of the steel plate concrete wall of this embodiment belongs to the field of building structure design, and involves a layout scheme of a steel plate concrete steel pipe-reinforcement combination module of a nuclear power plant. Steel pipes are set in the positions where cables or pipes need to be passed through the steel plate concrete instead of ordinary steel bar-type reinforcements. The steel pipes themselves can be used as reinforcements and also as reserved holes for other professional items to pass through the wall. The steel pipes can be welded in a conventional way to reduce the workload of punching and plug welding the reinforcement. When laying cables and pipes during the equipment installation stage, the damage to the steel plate concrete composite structure caused by opening holes can be avoided, and the impact on the design strength of the overall structural module can be avoided. The problem of laying reserved items for the steel plate concrete composite structure is solved, effectively promoting the development of construction and installation integration.

[0064] Steel pipe-reinforced steel plate concrete composite structure This scheme uses steel pipes to replace steel reinforcement in the cable and pipeline locations, which can ensure equivalent structural strength, avoid damage to the reinforcement in the structure without drilling during construction, ensure the overall integrity of the modular structure, and greatly reduce the difficulty of cable laying during the equipment installation stage. This method is simple and efficient and suitable for modular construction. This provides a simple and effective layout scheme to improve the modularity of the steel plate concrete composite structure, optimize the construction steps while ensuring the structural strength and integrity, and improve economic benefits.

[0065] This layout scheme is particularly suitable for application scenarios such as nuclear power plants that require the layout of a large number of through pipelines and have high requirements for strength. Steel pipes are used instead of tie rods in local steel plate concrete structures in nuclear power plants. While meeting structural design requirements, the construction flexibility of the steel plate concrete composite structure is improved, the construction difficulty is reduced, and the economy is improved.

[0066] Example 3

[0067] This embodiment is basically the same as the embodiment 2, except that the connection method between the sleeve 3 and the wall panel 1 is different. In this embodiment, Figures 5 to 9 As shown, the wall panel module of the steel plate concrete wall also includes a connecting component 4, which includes a first gasket 41, a second gasket 42 and a third gasket 43. The two ends of the sleeve 3 are respectively inserted into the connecting holes corresponding to the tie positions of the two wall panels 1. The first gasket 41 and the second gasket 42 are both sleeved on one end of the sleeve 3, and are respectively located on the outside and inside of the connecting hole penetrated by the end of the sleeve 3 to clamp and fix the wall panel 1 where the connecting hole is located. The third gasket 43 is sleeved on the other end of the sleeve 3, and is located on the outside of the connecting hole penetrated by the other end of the sleeve 3, thereby clamping and fixing the two wall panels 1 together with the first gasket 41.

[0068] After the steel tube-reinforced steel plate concrete unit is installed, it is difficult to avoid the modification of the path of the items passing through the wall later. In Example 2, the sleeve 3 is fixed by welding, which is more suitable for the situation where the cable route can be determined in advance. The sleeve 3 and the reinforcing bar 2 are welded together, and the strength of the wall panel 1 will not change due to subsequent dismantling and welding. The installation method of this embodiment adopts a mechanical structure connection, which is fixed by clamping and tightening. Compared with the welding connection method in Example 2, it can solve the problem of difficulty in dismantling and modifying caused by temporary modification of the cable path after the module is formed and in place, and provides an installation scheme for the rear steel pipe of the steel plate concrete steel tube-reinforced combined module.

[0069] In order to avoid the damage to the steel plate concrete composite structure caused by the modification of the cable and pipeline laying path during the equipment installation stage, this embodiment can use the prefabrication method to connect the sleeve 3 and the tie rod 2 together, or use the post-connection method to modify the path. That is, before installation, only a hole is opened at the steel plate at the modified position, and the sleeve 3 and the connection component 4 are placed. After installation, the post-installed steel pipe component (sleeve 3 and connection component 4) can replace the role of the original position tie rod, avoiding the impact on the design strength of the overall structural module, and at the same time solving the construction difficulties caused by the modification of items after the steel plate concrete composite module is installed in place. Compared with welding, it is more convenient for later dismantling and modification, and has a smaller impact on the structural balance.

[0070] In this embodiment, the second gasket 42 is connected to the sleeve 3 by welding.

[0071] In this embodiment, Figure 6 and Figure 7 As shown, both ends of the sleeve 3 are provided with external threads, the inner holes of the first gasket 41 and the third gasket 43 are provided with internal threads, and the first gasket 41 and the third gasket 43 are both fastened to the sleeve 3 by threads. Thus, the movement of the gasket on the sleeve 3 is realized through the threaded fit, ensuring that the gasket can press against the wallboard 1.

[0072] In this embodiment, the steel pipe assembly (sleeve 3 and connection assembly 4) takes the sleeve 3 with an outer diameter of 115 mm as an example. The steel pipe assembly is divided into 4 parts. The first part is the sleeve 3, and the second part is the third gasket 43 and the first gasket 41 and the second gasket 42. The third gasket 43 has an inner diameter of 115 mm and an outer diameter of 150 mm. The first gasket 41 and the second gasket 42 have an inner diameter of 115 mm and an outer diameter of 135 mm. Before installation, the sleeve 3 and the second gasket 42 are welded and connected, and then the sleeve 3 is inserted into the wall panel 1, and then the first gasket 41 and the third gasket 43 are fastened by threaded connection. The thickness of the wall panel 1 (wall thickness) is the thickness between the first gasket 41 and the third gasket 43.

[0073] This embodiment aims to solve the problem that when there is a need to modify the new path, the construction is difficult and the integrity of the module will be damaged. It provides a post-installed steel pipe-reinforcement arrangement scheme that is easy to construct, does not damage the integrity of the module, and can effectively solve the problem of modifying the path of items after the module is installed. The post-installed steel pipe assembly only needs to open holes on the steel plates on both sides. After the post-installed steel pipe assembly is installed, it is not fixed by welding, but tightened by threading, which will hardly affect the overall integrity of the module structure. This method greatly reduces the difficulty of cable path modification during the equipment installation stage, and the construction is simple and efficient, effectively ensuring the overall strength of the structure.

[0074] Example 4

[0075] The nuclear industrial plant of this embodiment, the wall panels and / or floor panels of the nuclear industrial plant include concrete units, and the concrete units are formed by pouring concrete in the wall panel modules using the wall panel modules of the steel plate concrete walls in Examples 1 to 3 as casting templates.

[0076] Example 5

[0077] The concrete unit manufacturing method of this embodiment includes the following steps:

[0078] Prefabricate the wall panel modules of the steel plate concrete wall in Examples 1 to 3;

[0079] Lift and install the wall panel modules at the set position;

[0080] Concrete is poured within the wall panel modules to form concrete units.

[0081] The prefabricated wall panel modules of the steel plate concrete wall in Examples 1 to 3 include connecting the tie rods 2 at the tie positions in the first area of ​​the wall panel 1; and connecting the sleeves 3 at the tie positions in the second area of ​​the wall panel 1.

[0082] The tie rod 2 can be specifically connected by welding using a perforation plug welding method.

[0083] In the process of prefabricating the wall panel module, the step of "connecting the sleeve 3 at the tie position in the second area of ​​the wall panel 1" can be directly performed on the existing wall panel module to perform the modification. Before the wall panel module is hoisted in place, it can be used to form the wall panel module in Example 2, that is, the sleeve 3 is connected by welding; and after the wall panel module is hoisted in place, if there is a situation where the through-wall pipeline temporarily changes its position, it can be modified on the existing wall panel module or any prefabricated wall panel module in Examples 1 to 3 to form the wall panel module of Example 3 (or Example 1, Example 2 combined with Example 3), that is, after the wall panel module is hoisted and installed at the set position, the following steps are also included to allow the wall panel module to allow the through-wall pipeline that has temporarily changed its position to pass through:

[0084] A connection hole is provided on the wall panel 1 at the tie position corresponding to the place where the through-wall pipeline passes;

[0085] Insert the two ends of the sleeve 3 with the second gasket 42 into the connection holes of the two wall panels 1 respectively, so that the second gasket 42 is pressed against the inner side of one connection hole;

[0086] Fix the first gasket 41 on the sleeve 3 and press against the outer side of the connecting hole corresponding to the second gasket 42;

[0087] The third gasket 41 is fixed on the sleeve 3 and pressed against the outer side of the other connecting hole.

[0088] In this embodiment, the outer diameters of the first gasket 41 and the second gasket 42 are consistent, and both are smaller than the diameter of the third gasket 41. The apertures of the connecting holes on the two wall panels 1 are inconsistent. The aperture of the second connecting hole pressed by the third gasket 43 is larger than the first connecting hole pressed by the first gasket 41 and the second gasket 42. The aperture of the second connecting hole is larger than the first gasket 41 and the second gasket 42, and smaller than the third gasket 43. The aperture of the first connecting hole is smaller than the first gasket 41 and the second gasket 42. The sleeve 3 with the second gasket 42 passes through the wall panel 1 through the second connecting hole to avoid interference.

[0089] Combined with the specific structural content mentioned in Example 3, the outer diameter of the steel pipe assembly (sleeve 3 and connection assembly 4) is first determined according to the size of the wall-penetrating item. In this embodiment, the sleeve 3 with an outer diameter of 115 mm is taken as an example. The steel pipe assembly is divided into 4 parts, the first part is the sleeve 3, and the second part is the third gasket 43 and the first gasket 41 and the second gasket 42. The third gasket 43 has an inner diameter of 115 mm and an outer diameter of 150 mm, and the first gasket 41 and the second gasket 42 have an inner diameter of 115 mm and an outer diameter of 135 mm.

[0090] Make the steel pipe assembly: Determine the reserved length of the two ends of the steel pipe according to the wall thickness, and thread it, and weld and fix the second gasket 42 to the end of the threaded position of the steel pipe end. The remaining first gasket 41 and third gasket 43 are standby for installation.

[0091] The first step in installing the steel pipe assembly is to make holes on the steel plate (wall panel 1) of the steel plate concrete steel pipe-reinforcement combination module, a 140mm round hole (second connection hole) on the front, and a 124mm round hole (second connection hole) on the back, and remove the reinforcement at the corresponding position, such as Figure 5 . The second step is to insert one end of the sleeve 3 with the welded second gasket 42 from the large round hole on the front of the module until the gasket 2 is against the small round hole on the back steel plate. The third step is to thread and tighten the first gasket 41 from the back end, and clamp the back steel plate with the second gasket 42. The fourth step is to thread and tighten the third gasket 43 from the front end to the front steel plate. At this point, the installation of the rear steel sleeve assembly is complete.

[0092] In the construction of traditional steel plate concrete units, there is no good solution to the problem of temporary modification of the item path after the module is installed in place. Usually, the entire module is reprocessed, or a destructive demolition and modification solution is used. In this embodiment, the installation method of the post-installed steel pipe assembly effectively solves the above problem, and the damage to the steel plate concrete unit can be almost ignored, which effectively improves the construction efficiency and greatly reduces the construction cost caused by design changes.
