Description

Technical Field

[0001] The invention relates to the field of nuclear power building structures, and in particular to a modular assembly steel cage device and method. Background Art

[0002] The number of large industrial buildings, high-rise buildings, deep foundation pits and other projects has gradually increased, which has put forward higher requirements on the construction efficiency and construction methods of such projects. Since nuclear power plant projects are large-scale systematic projects, all types of construction must meet standardized construction, and modular construction can better meet the requirements of nuclear power projects. However, compared with the traditional prefabricated structure in civilian use, in nuclear power plants, due to the relatively irregular structure of the plant and the relatively thick wall panels, the weight of the prefabricated components is relatively large, which puts forward high requirements for hoisting. A new type of mortise and tenon concrete structure is disclosed in a Chinese patent (publication number CN21848862U, publication date 20221227), which connects the concrete parts by sliding connection of dovetail blocks and dovetail grooves, and then inserts the pin key blocks into the pin key grooves to complete the limit to meet the splicing requirements. However, the layout of nuclear power plant buildings is generally relatively compact, and the hoisting area and hoisting capacity of hoisting equipment are generally limited. Therefore, the use of traditional prefabrication in nuclear power plants has great limitations, and through the experience of existing nuclear power projects, it is found that the economic efficiency of projects that adopt modular construction and installation is relatively general.

[0003] The construction of nuclear power plants adopts the method of steel cage assembly, which is a better choice to improve construction efficiency and construction economy, and overcomes the shortcomings of prefabricated buildings and modular construction. In the process of steel cage construction, after the steel cage module is completed, the steel cage modules are assembled together after hoisting in place. Common assembly methods include welding connection and mechanical connection. After the steel cage is in place, it needs to be kept in a hoisting state or supported by manual assistance before the steel cage connection is completed. The connection of a steel bar generally takes 5 to 10 minutes, and 2 to 3 people are required to work at the same time, and the connection efficiency is low. In addition, the steel bars used in nuclear power construction projects have a large diameter and a long lap length. Due to the long length, it is difficult to use the lap method, and the welding connection method of large-diameter steel bars has a low operating efficiency and is not suitable for use. Therefore, the connection method for assembling steel cage modules in nuclear power plants should adopt a mechanical connection method, and the current mainstream connection method of mechanical connection is sleeve connection. The steel cage sleeve needs to adopt a "two-piece set" or "three-piece set" sleeve. The sleeve itself has a high material cost, so the cost is higher than that of a conventional sleeve. Moreover, under actual working conditions on site, the steel cage is affected by factors such as hoisting deformation and prefabrication errors during the hoisting process, and the steel bars that need to be connected have certain eccentricity and gaps, which affects the quality and efficiency of the construction. Summary of the invention

[0004] The purpose of the present invention is to provide a modular steel cage assembly device and method in view of the defects existing in the prior art. A sliding and clamping connection component is installed at the splicing position of different steel cages to achieve rapid splicing. The connection component includes a groove steel and a protrusion steel connected to the splicing position of the steel cage. The slide groove on the groove steel and the slider on the protrusion steel can be slidably spliced. After the splicing is completed, a clamping fixation is formed to resist the detachment of the steel cage. The groove steel and the protrusion steel can reinforce the edge and splicing position of the steel cage, thereby resisting deformation during the lifting process of the steel cage. The deformation of the groove steel and the protrusion steel is small during lifting, thereby ensuring the accuracy and smoothness of the sliding splicing, and realizing precision control of the splicing of different steel cages.

[0005] The first object of the present invention is to provide a modular assembly steel cage device, using the following scheme:

[0006] It includes a steel cage and a connection component, which includes a groove steel and a convex block steel. One side of the groove steel is connected to the steel cage, and the other side is provided with a slide groove. One side of the convex block steel is connected to the steel cage, and the other side is provided with a slider. The slide groove and the slider are slidably matched, and after matching, the displacement of the groove steel and the convex block steel in a direction perpendicular to the sliding direction is constrained to enable different steel cages to be assembled and spliced.

[0007] Furthermore, a flange plate is provided on the side of the groove-shaped steel away from the slide groove and on the side of the protrusion-shaped steel away from the slide block, and the flange plate is overlap-welded with the steel cage to form a welding section.

[0008] Furthermore, the steel cage includes a steel mesh, and the two sides of the flange plate are respectively connected with the steel mesh to form welding sections.

[0009] Furthermore, the connection assembly is located between different steel cages, and the grooved steel and the protruding block steel of the connection assembly serve as structural members of the steel cages.

[0010] Furthermore, the grooved steel and the protruding steel are connected to the edges of the splicing positions of the reinforcement cage.

[0011] Furthermore, the cross-sectional shape of the slide groove is a groove with an opening, and the cross-sectional shape of the slider is adapted to the groove to constrain the displacement of the slider relative to the groove in the direction of the plane where the cross-sectional shape is located.

[0012] Furthermore, the groove is in a dovetail shape, and the slider is also in a dovetail shape that matches the groove.

[0013] Furthermore, when different steel cages are horizontally spliced, the grooved steel and the protruding block steel are vertically distributed along the splicing position; when different steel cages are vertically spliced, the grooved steel and the protruding block steel are non-throughout distributed horizontally along the splicing position.

[0014] The second object of the present invention is to provide a construction method for modularly assembling a reinforcement cage device as described in the first object, comprising:

[0015] Prefabricated steel cage, when prefabricating the steel cage, the groove steel and the convex steel are fixed as structural parts at the preset splicing position of the steel cage;

[0016] Lift the steel cages for splicing, so that the groove steel and the convex steel between the two steel cages to be spliced ​​are slidably matched until the groove steel and the convex steel are in place;

[0017] Fix the position of the spliced ​​steel cage and pour concrete to form a concrete wall.

[0018] Furthermore, when prefabricating the steel cage, the splicing position and the state after splicing are determined, and the grooved steel and the protruding steel are installed accordingly. During the sliding cooperation between the grooved steel and the protruding steel, the relative position of the steel cage is corrected by utilizing the guiding effect of the slider when cooperating with the groove.

[0019] Compared with the prior art, the present invention has the following advantages and positive effects:

[0020] (1) In view of the problem of great difficulty and poor precision in splicing of prefabricated steel cages used in the construction of nuclear power plants, a sliding clamping connection component is installed at the splicing position of different steel cages to achieve rapid splicing. The connection component includes a groove steel and a protrusion steel connected to the splicing position of the steel cage. The slide groove on the groove steel and the slider on the protrusion steel can be slidably spliced ​​to form a clamping fixation to resist the separation of the steel cage after the splicing is completed. The groove steel and the protrusion steel can reinforce the edge and splicing position of the steel cage, thereby resisting the deformation of the steel cage during the hoisting process. The deformation of the groove steel and the protrusion steel is small during hoisting, thereby ensuring the precision and smoothness of the sliding splicing, and realizing the precision control of the splicing of different steel cages. The position between different steel cages is corrected by using the direction of the sliding splicing process along the longitudinal direction of the groove steel and the protrusion steel, so that the different steel cages can be accurately located at the set position to meet the needs of subsequent concrete pouring.

[0021] (2) The grooved steel and the convex steel are matched with a combination of a slide groove and a slider on one side, and a flange plate on the other side. The flange plate and the steel cage are overlapped to form a welding section. Each flange plate is connected to the steel cage respectively. While establishing a connection with the steel cage, the edge or other splicing positions of the steel cage can be reinforced. When multiple steel cages are spliced, multiple splicing positions located at the edge or other positions of the steel cage can be reinforced respectively, thereby improving the overall structural strength and stability of the steel cage, thereby resisting deformation during lifting and meeting the precision requirements of the steel cage.

[0022] (3) The slide groove and the slider can form a snap-fit ​​state after being matched, which can limit their position in the non-sliding direction. At the splicing position of the steel cage, the relative sliding direction of the slide groove and the slider is generally perpendicular to the distribution direction of the two steel cages, so that the two steel cages can be connected by the cooperation of the slide groove and the slider, avoiding the separation and dislocation between the steel cages in the horizontal direction, and meeting the assembly connection requirements of the steel cage.

[0023] (4) The cross-section of the chute and the slider is dovetail-shaped, and the fit between the two is a close fit with small clearance. The close fit enables the dovetail-shaped slider to be accurately positioned in the dovetail-shaped chute. After the dovetail-shaped slider and the dovetail-shaped chute are matched, its position in all directions is relatively fixed, and it can only move along the direction of the chute, which can ensure that the steel cage can be accurately positioned at the required position after hoisting and matching, without offset or shaking.

[0027] Example 1

[0028] In a typical embodiment of the present invention, Figure 1 As shown, a modular assembly steel cage device is provided.

[0029] In nuclear power construction projects, the steel bars have large diameters and long lap lengths, making it difficult to use lap joints. Welding connections are inefficient and not suitable, and mainstream sleeve connections are expensive. Based on this, this embodiment provides a modular assembly steel cage device suitable for assembling nuclear power steel cage 8 modules. The sliding card connection assembly can achieve rapid splicing, improve the connection efficiency of the steel cage 8, and at the same time, the connection assembly can be used to reinforce the steel cage 8, thereby improving the strength of the steel cage 8 to resist deformation during the hoisting process and improve the accuracy of the steel cage 8 after assembly.

[0030] like Figure 1As shown, the modular assembly steel cage device includes a steel cage 8 and a connecting component, the connecting component includes a grooved steel 2 and a protruding steel 3, the grooved steel 2 and the protruding steel 3 are installed on the steel cage 8 to form a modular structure, when different steel cages 8 are spliced, the clamping structure formed by the sliding fit of the grooved steel 2 and the protruding steel 3 is utilized to realize the splicing between different steel cages 8, and resist the detachment and deviation between the steel cages 8.

[0031] The steel cage 8 is a basic component in the construction of a nuclear power plant. In this embodiment, as the main body to be connected and assembled, the groove steel 2 is connected to the steel cage 8 on one side, and a slide 4 is provided on the other side, which can cooperate with the protrusion steel 3. The protrusion steel 3 is connected to the steel cage 8 on one side, and a slider 5 is provided on the other side. The slider 5 can cooperate with the slide 4 on the groove steel 2. The fast splicing of the steel cage 8 is achieved by sliding the slide 4 and the slider 5, and after the splicing is completed, a clamping fixation is formed to prevent the steel cage 8 from detaching. At the same time, the groove steel 2 and the protrusion steel 3 can also reinforce the splicing positions such as the edge and middle of the steel cage 8 to resist the deformation of the steel cage 8 during the hoisting process.

[0032] Under actual working conditions on site, the steel cage 8 is affected by hoisting deformation and prefabrication errors, and the connected steel bars have eccentricity and gaps, which affect the construction quality and efficiency. In this embodiment, on the one hand, the grooved steel 2 and the convex steel 3 are used to reinforce the splicing position of the steel cage 8 to resist deformation. On the other hand, the deformation is small during hoisting, ensuring the accuracy and smoothness of the sliding splicing, thereby improving the construction quality and efficiency.

[0033] The sliding clamping connection assembly realizes the rapid splicing of different steel cages 8, improving the connection efficiency. The grooved steel 2 and the convex steel 3 can form a clamping fixation to resist the separation of the steel cage 8 after the splicing is completed by using the rigidity of their bodies, thereby ensuring the stability of the connection. The splicing position of the steel cage 8 is reinforced to resist deformation during the hoisting process, and the accuracy and smoothness of the sliding splicing are guaranteed, so that the precision control of the splicing of different steel cages 8 is realized, and the construction quality is improved.

[0034] When a conventional wall is constructed, the edges of two steel cages 8 are spliced, and the grooved steel 2 and the protruding steel 3 are located at the edges of the steel cages 8; when a T-shaped wall is formed, the grooved steel 2 is installed on the side of one steel cage 8, and the protruding steel 3 is installed on the edge of the other steel cage 8. The splicing of the grooved steel 2 and the protruding steel 3 forms a T-shaped structure, which enhances the connection strength and integrity between the steel cages 8 at the T-shaped intersection. When the T-shaped wall is subjected to external forces, such as lateral pressure or vertical pressure, the connection components at the T-shaped intersection can transmit and disperse the forces between different steel cages 8. Therefore, the distribution positions of the grooved steel 2 and the protruding steel 3 are determined according to the splicing positions, and after they are installed in the steel cage 8, the steel cage 8 can be reinforced.

[0035] It is understandable that since a single steel cage 8 is often spliced ​​with multiple other steel cages 8, on this basis, the grooved steel 2 and the protrusion steel included in the connection assembly can be reinforced from multiple positions of the steel cage 8, thereby ensuring the structural stability of the steel cage 8.

[0036] The structure of the grooved steel 2 and the convex steel 3 is obtained by modifying or customizing the I-shaped steel as the basic structure. Figure 1 As shown, the side of the groove steel 2 away from the slide 4 and the side of the protrusion steel 3 away from the slider 5 are provided with a flange plate 7, and the flange plate 7 and the steel cage 8 are overlap-welded to form a welding section 6. The connection strength between the connection assembly and the steel cage 8 is enhanced. Through welding, the flange plate 7 is tightly combined with the steel mesh 1 of the steel cage 8, so that the connection assembly can better serve as a structural member of the steel cage 8 and participate in the overall force system of the steel cage 8.

[0037] The flange plate 7 is connected to the steel mesh 1 on both sides to form a welding section 6, which transmits the force of the connection assembly to each part of the steel cage 8, thereby improving the integrity and stability of the steel cage 8. At the same time, when the steel cage 8 is subjected to external force, the flange plate 7 can also play a certain role in strengthening and supporting, thereby preventing the steel cage 8 from being deformed or damaged at the connection part.

[0038] When modularly assembling the steel cage 8 using mechanical connection, the main difficulty currently faced is to ensure that the axial and radial deviations caused by the docking of the steel cage 8 are within a controllable range after the steel cage 8 is hoisted. In this regard, in this embodiment, by using the grooved steel 2 and the protruding steel 3 to form a mechanical connection, the requirements for the deformation of the steel cage 8 and the error of the main bars of the steel cage 8 in the horizontal and vertical directions during the modular assembly of the steel cage 8 can be greatly reduced. Through lap welding and structural extrusion between the grooved steel 2 and the protruding steel 3, the efficiency of engineering construction can be greatly improved while ensuring the structural strength.

[0039] At the stage where the lifting of the steel cage 8 module is completed, compared with the traditional sleeve connection which requires the participation of multiple people at the same time and takes a long time to operate, the steel cage 8 module is connected by the grooved steel 2 and the protruding steel 3 proposed in this embodiment. On site, it is only necessary to ensure that the groove 4 and the slider 5 of the grooved steel 2 and the protruding steel 3 are snapped into connection to form a male and female head snap-in connection state, so that an equal strength connection can be achieved. Therefore, the workload on site can be greatly reduced, the construction time can be shortened, the personnel input can be reduced, and the safety of on-site construction can be ensured.

[0040] The steel cage 8 module is connected by grooved steel 2 and protruding steel 3, which greatly reduces the requirements for the working space and has strong environmental adaptability. The original sleeve connection method requires assembling two steel cage 8 components together between the narrow steel bar gap. The grooved steel 2 and the protruding steel 3 form a male and female head connection during lifting to complete the assembly of the steel cage 8.

[0041] like Figure 1 As shown, when the steel cages 8 are horizontally butt-jointed in sequence to form a continuous wall structure, the connecting assembly is located between different steel cages 8 and connected to the edge of the splicing position of the steel cages 8, so that the connecting assembly can play a key connecting and reinforcing role at the splicing position of the steel cages 8. Connecting at the edge position can better control the splicing accuracy of the steel cages 8, and can effectively resist the deformation and separation of the steel cages 8 at the splicing during lifting and use.

[0042] It should be pointed out that the existing steel cage 8 connection can generally only realize the connection of single-layer and double-layer steel cage 8 meshes. When connecting the steel cage 8 of multi-layer steel mesh 1, it is difficult to achieve modular assembly due to the limitations of steel bar spacing, sleeve volume and personnel operation, and can only be connected in layers. When using the connection assembly in this embodiment, it is only necessary to make the width of the grooved steel 2 and the protrusion steel 3 according to the number of layers and thickness of the steel bars to effectively connect the multi-layer steel mesh 1. At the same time, the grooved steel 2 and the protrusion steel 3 can also be adapted to steel cages 8 of different thicknesses respectively, and form a connection to realize the assembly of steel cages 8 of different thicknesses, which greatly improves the scope of application. It can not only cover the coverage of the existing technology, but also is suitable for the efficient assembly of heavy shear wall steel cages 8 with multi-layer steel mesh 1.

[0043] When the steel cage 8 is assembled using the connection assembly in this embodiment, the current vertical operation method of wall steel bar binding can be improved to horizontal binding. The steel bars are not in an upright state during the binding process, which eliminates the possibility of instability of the steel cage 8 and greatly improves construction safety.

[0044] like Figure 1 As shown, when different steel cages 8 are horizontally spliced, the grooved steel 2 and the convex steel 3 are vertically distributed along the splicing position, which can provide uniform connection and reinforcement effect in the entire length direction of the horizontal splicing, ensuring that the horizontally spliced ​​steel cage 8 has sufficient integrity and stability in the vertical direction.

[0045] In other optional embodiments, when different steel cages 8 are vertically spliced, the grooved steel 2 and the protruding steel 3 are non-through-length distributed in the horizontal direction of the splicing position. For example, multiple sections of grooved steel 2 are distributed at intervals, and multiple sections of protruding steel 3 are distributed at intervals. On the one hand, the stress conditions in the horizontal direction are relatively complex, and the non-through-length distribution can better adapt to the stress characteristics during vertical splicing. On the other hand, it can reduce the misalignment state of the grooved steel 2 and the protruding steel 3 during the initial matching, reduce the space occupied during sliding matching, adapt to the compact working environment of the nuclear power plant, and can also reduce the use of materials and improve economic efficiency under the premise of meeting the connection and reinforcement requirements.

[0046] like Figure 1 As shown, the cross-sectional shape of the slide groove 4 is a groove with an opening, and the cross-sectional shape of the slider 5 is adapted to the groove, which can effectively restrict the displacement of the slider 5 relative to the groove in the plane direction of the cross-sectional plane, thereby ensuring the accuracy and smoothness of the sliding splicing. Through precise shape matching, the grooved steel 2 and the protruding steel 3 can be accurately aligned and connected during the splicing process, avoiding offset or jamming.

[0047] Specifically, the groove of the cross section of the chute 4 is in a dovetail shape, and the slider 5 is also in a dovetail shape that matches the groove. The dovetail structure has good guiding and self-locking properties. During the sliding splicing process, the dovetail chute 4 and the slider 5 can ensure that the connection components are spliced ​​in the correct direction, and after the splicing is completed, a stable clamping fixation can be formed to prevent the steel cage 8 from detaching. At the same time, the dovetail structure can also withstand a large load, improve the bearing capacity of the connection component, and further enhance the stability of the steel cage 8 after splicing.

[0048] In other optional embodiments, the cross-sectional shape of the slide groove 4 and the slider 5 can also be T-shaped, trapezoidal or other polygonal shapes, which can meet the requirements of sliding fit. At the same time, after fitting, the displacement of the groove steel 2 and the protrusion steel 3 perpendicular to the sliding direction is constrained to resist the horizontal separation and dislocation of the steel cage 8, so that different steel cages 8 can be assembled and spliced.

[0049] Specifically, the slide groove 4 and the slider 5 can form a clamping state after cooperation, which can limit their position in the non-sliding direction. At the splicing position of the steel cage 8, the relative sliding direction of the slide groove 4 and the slider 5 is generally perpendicular to the distribution direction of the two steel cages 8. The cooperation of the slide groove 4 and the slider 5 is used to achieve the connection between the two steel cages 8, avoiding the separation and dislocation between the steel cages 8 in the horizontal direction, and meeting the assembly connection requirements of the steel cages 8.

[0050] Example 2

[0051] In another typical embodiment of the present invention, Figure 1As shown, a construction method for modular assembly of a steel cage device is provided, using the modular assembly of a steel cage device as in Example 1.

[0052] like Figure 1 As shown, the construction method of the modular assembly steel cage device includes:

[0053] Prefabricate the steel cage 8, and fix the grooved steel 2 and the convex steel 3 as structural parts at the preset splicing position of the steel cage 8 when prefabricate the steel cage 8;

[0054] Lift the steel cage 8 for splicing, so that the groove steel 2 and the convex steel 3 between the two steel cages 8 to be spliced ​​are slidably matched until the groove steel 2 and the convex steel 3 are in place;

[0055] The position of the spliced ​​reinforcement cage 8 is fixed, and concrete is poured to form a concrete wall.

[0056] Among them, when prefabricating the steel cage 8, the splicing position and the state after splicing are determined, and the grooved steel 2 and the protruding steel 3 are installed accordingly. During the sliding cooperation between the grooved steel 2 and the protruding steel 3, the relative position of the steel cage 8 is corrected by utilizing the guiding effect of the slider 5 when cooperating with the groove.

[0057] By determining the splicing position in advance and installing the connection components, preparations can be made for the subsequent hoisting and splicing, which can ensure that the steel cage 8 can be spliced ​​quickly and accurately at the construction site, thereby improving construction efficiency; the sliding splicing characteristics of the connection components are utilized, and the steel cage 8 is quickly connected through the cooperation of the slide 4 and the slider 5. In this process, the grooved steel 2 and the protruding steel 3 not only play a connecting role, but also can constrain and adjust the splicing position of the steel cage 8 to ensure the precision and accuracy of the splicing.

[0058] As for the guiding function, the position of the steel cage 8 can be adjusted in real time during the hoisting and splicing process to ensure that the two steel cages 8 can be accurately spliced ​​together. For example, if the steel cage 8 is slightly offset during the hoisting process, the position of the steel cage 8 can be corrected through the sliding guiding function of the slider 5 in the groove, ensuring the accuracy and smoothness of the splicing, thereby improving the overall construction quality.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
