Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a built-in steel plate reinforced concrete wall system and its construction method. Background Technology

[0002] Heavy concrete, as a high-density, high-performance special engineering material, can effectively block gamma rays and X-rays by using high-density aggregates such as barite and magnetite. It is widely used in special engineering fields with stringent requirements for radiation protection and structural safety, such as nuclear power plants, particle accelerator devices, and hospital radiotherapy rooms.

[0003] For projects with high radiation protection requirements, the industry typically incorporates steel plates inside heavy concrete walls. On one hand, the steel plates act as a metallic shielding layer, further enhancing the overall radiation shielding effectiveness of the wall and compensating for any inherent weaknesses in the shielding of heavy concrete. On the other hand, the steel plates significantly improve the wall's seismic performance, ensuring structural reliability under complex working conditions.

[0004] The current construction process for heavy concrete walls with built-in steel plates generally involves first hoisting the steel plates into their predetermined positions, and then pouring heavy concrete on both sides of the steel plates. However, this construction process has significant shortcomings: the steel plates built into the heavy concrete walls are usually quite thick and have a high overall weight, which greatly increases the difficulty of hoisting and accurately positioning the steel plates; at the same time, to ensure the integrity of the wall's radiation shielding, it is necessary to avoid allowing the tie bolts used to fix the concrete support formwork to pass through the steel plates. This not only further increases the difficulty and cost of on-site construction, but may also affect the forming quality of the heavy concrete wall due to improper formwork support.

[0005] Therefore, there is an urgent need for a built-in steel plate heavy concrete wall system and its construction method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a built-in steel plate heavy concrete wall system and its construction method, which reduces the difficulty of steel plate hoisting and positioning, reduces construction costs, and ensures the integrity of the wall's radiation shielding and the forming quality of the heavy concrete wall system.

[0007] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, a built-in steel plate heavy concrete wall system is provided, comprising a multi-layer main structure connected sequentially in a vertical direction. The main structure includes steel plate components, mounting bases, and heavy concrete layers. The steel plate components are disposed on the mounting bases and include multiple sub-steel plates stacked along their thickness direction. Heavy concrete layers are disposed on both sides of the steel plate components along their thickness direction. Tie bolts can pass through the mounting bases. The mounting base of the lowest main structure can be disposed on a base plate. In two adjacent main structures, the mounting base of the upper main structure is disposed on top of the steel plate components of the lower main structure.

[0008] Optionally, the mounting base includes multiple mounting positions, each corresponding to a multiple sub-steel plate of the steel plate assembly. Each mounting position is provided with multiple mounting slots arranged in a matrix. The bottom of each sub-steel plate is provided with multiple mounting parts, each corresponding to a multiple mounting slot of the corresponding mounting position. The mounting parts can be inserted into the corresponding mounting slots.

[0009] Optionally, a pouring space is provided on the mounting base of the lowest main structure. A flow gap is formed between the groove wall of the mounting groove and the corresponding mounting part. Multiple flow gaps can be connected to the pouring space, and heavy concrete can flow into the pouring space through the flow gaps.

[0010] Optionally, in the two adjacent main structures, a first protrusion is provided on one of the top of the lower heavy concrete layer and the bottom of the upper heavy concrete layer, and a first groove is provided on the other of the top of the lower heavy concrete layer and the bottom of the upper heavy concrete layer, and the first protrusion can be embedded in the first groove. A second protrusion is provided on the bottom of the lowest heavy concrete layer and on the bottom plate, and a second groove is provided on the other side of the bottom of the lowest heavy concrete layer and on the bottom plate, and the second protrusion can be embedded in the second groove.

[0011] Optionally, metal isolation plates are installed at the interface between two adjacent heavy concrete layers in the vertical direction and at the interface between the lowest heavy concrete layer and the base slab. The metal isolation plates are used to isolate radiation.

[0012] Optionally, the first side of the sub-steel plate is provided with a plurality of first connecting parts arranged in a matrix, and the second side of the sub-steel plate is provided with a plurality of first connecting grooves, the plurality of first connecting grooves corresponding one-to-one with the plurality of first connecting parts, and any first connecting part of the sub-steel plate can be inserted into the corresponding first connecting groove of the adjacent sub-steel plate.

[0013] Optionally, a guide groove extending along the thickness direction of the sub-steel plate is provided on one of the first connecting part and the first connecting groove wall, and a guide part is provided on the other of the first connecting part and the first connecting groove wall, the guide part being slidably embedded in the guide groove.

[0014] Optionally, the mounting base is provided with multiple through holes spaced apart along the extension direction of the main structure, and the through holes extend along the thickness direction of the main structure, so that the tie bolts can pass through any one of the through holes.

[0015] Secondly, a construction method for a built-in steel plate reinforced concrete wall system is provided, applicable to the built-in steel plate reinforced concrete wall system of the first aspect, comprising the following steps: S1. Install the mounting base of the lowest main structure onto the base plate, and install the multiple sub-steel plates of the lowest main structure onto the corresponding mounting bases. S2. Install support templates on both sides of the bottom steel plate assembly along its thickness direction, and install multiple tie bolts on the upper and lower sides of the bottom steel plate assembly. The tie bolts located below the bottom steel plate assembly pass through the bottom mounting base and the two support templates, and the tie bolts located above the bottom steel plate assembly pass through the two support templates. S3. Pour heavy concrete to form the heavy concrete layer of the bottom main structure; after the heavy concrete has solidified, remove the multiple tie bolts and support formwork of the bottom layer. S4. Install the mounting base of the main structure of the layer to be installed on top of the installed uppermost steel plate assembly, and install multiple sub-steel plates of the layer to be installed on the mounting base of the layer to be installed. S5. Install support templates on both sides of the steel plate assembly to be installed along its thickness direction, and install multiple tie bolts on the upper and lower sides of the steel plate assembly to be installed. The tie bolts located below the steel plate assembly to be installed pass through the mounting base of the layer to be installed and the two support templates, and the tie bolts located above the steel plate assembly to be installed pass through the two support templates. S6. Pour heavy concrete to form the heavy concrete layer of the main structure of the layer to be installed; after the heavy concrete has solidified, remove the multiple tie bolts and support formwork of the layer to be installed. S7. Repeat steps S4 to S6 until the multi-layer main structure is installed.

[0016] Optionally, the main structure includes a plurality of steel plate assemblies arranged continuously along its extension direction; In steps S1 and S4, when installing multiple sub-steel plates onto the mounting base, multiple steel plate assemblies are installed sequentially along the extension direction of the main structure, and when installing each steel plate assembly, the multiple sub-steel plates of the installed steel plate assembly are installed one by one onto the mounting base of the corresponding layer.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a built-in steel plate heavy concrete wall system and its construction method. The built-in steel plate heavy concrete wall system includes a multi-layer main structure. Each layer of the main structure's steel plate assembly includes multiple sub-steel plates stacked along its thickness direction, resulting in smaller thickness and height for each sub-steel plate. Therefore, during hoisting and positioning, the hoisting structure only needs to move the smaller sub-steel plates, significantly reducing the difficulty of hoisting and positioning, lowering the lifting capacity requirements of the hoisting structure, and reducing construction costs. The steel plate assemblies are installed on mounting bases, and adjacent layers of steel plate assemblies are connected by a mounting base. This allows tie bolts to connect the formwork structures on both sides by passing through the mounting bases without passing through the steel plate assemblies, reducing construction difficulty while ensuring the integrity of the wall's radiation shielding and the forming quality of the heavy concrete wall system. Compared with existing technologies, the construction method of the built-in steel plate heavy concrete wall system provided by this invention adopts a layered construction approach, with each layer constructed in stages, significantly reducing the difficulty of each layer's construction, improving the accuracy of each layer's construction, and ensuring the forming quality of the heavy concrete wall system.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0024] Example 1 like Figures 1 to 6 As shown, this embodiment provides a built-in steel plate heavy concrete wall system, which reduces the difficulty of steel plate hoisting and positioning, reduces construction costs, and ensures the integrity of the wall's radiation shielding and the forming quality of the heavy concrete wall system.

[0025] See Figure 1 The built-in steel plate heavy concrete wall system includes a multi-layer main structure 10 connected sequentially in the vertical direction. The main structure 10 includes a steel plate assembly 100, a mounting base 200, and a heavy concrete layer 300. The steel plate assembly 100 is disposed on the mounting base 200. The steel plate assembly 100 includes components along its thickness direction ( Figure 1Multiple steel plates 110 are stacked in the X direction. The steel plate assembly 100 has heavy concrete layers 300 on both sides along its thickness direction. Tie bolts can pass through the mounting base 200. The mounting base 200 of the lowest main structure 10 can be set on the base plate 20. In two adjacent main structures 10, the mounting base 200 of the upper main structure 10 is set on the top of the steel plate assembly 100 of the lower main structure 10.

[0026] The built-in steel plate heavy concrete wall system provided in this embodiment includes a multi-layer main structure 10. Each layer of the main structure 10 has a steel plate assembly 100, which includes multiple sub-steel plates 110 stacked along its thickness direction. This results in a smaller thickness and height for each sub-steel plate 110. Therefore, during hoisting and positioning, the hoisting structure only needs to move the smaller sub-steel plates 110, significantly reducing the difficulty of hoisting and positioning, lowering the lifting capacity requirements of the hoisting structure, and reducing construction costs. The steel plate assemblies 100 are mounted on mounting bases 200. Adjacent layers of steel plate assemblies 100 are connected by a mounting base 200. During construction, tie bolts 50 can connect the formwork structures on both sides by passing through the mounting base 200 without passing through the steel plate assemblies 100. This reduces construction difficulty while ensuring the integrity of the wall's radiation shielding and the forming quality of the heavy concrete wall system.

[0027] For example, see Figure 1 The built-in steel plate heavy concrete wall system includes a two-layer main structure 10.

[0028] Optionally, see Figure 1 , Figure 2 and Figure 3 The mounting base 200 includes multiple mounting positions 210, each corresponding to a different sub-steel plate 110 of the steel plate assembly 100. Each mounting position 210 has multiple mounting slots 211 arranged in a matrix. Each sub-steel plate 110 has multiple mounting parts 111 on its bottom, each corresponding to a different mounting slot 211 in the mounting position 210. The mounting parts 111 can be inserted into their respective mounting slots 211. This arrangement allows the mounting parts 111 to be quickly and accurately installed into the mounting slots 211, thereby enabling the sub-steel plates 110 to be quickly and accurately installed onto the mounting base 200. This helps reduce construction difficulty, improve construction accuracy, and accelerate construction efficiency.

[0029] Specifically, the mounting base 200 includes multiple cubic blocks, each of which corresponds one-to-one with a multiple sub-steel plate 110 of the steel plate assembly 100, and each cubic block is provided with a mounting position 210.

[0030] For example, see Figure 2The multiple mounting slots 211 on the mounting base 200 are preferably arranged symmetrically along both the width and length directions of the mounting base 200.

[0031] In this embodiment, see Figure 2 , Figure 3 and Figure 4 The lowest main structure 10 has a pouring space 220 on its mounting base 200. A flow gap is formed between the wall of the mounting groove 211 and the corresponding mounting part 111. Multiple flow gaps connect to the pouring space 220, allowing heavy concrete to flow into it. This design ensures that the heavy concrete in the pouring space 220 forms a unified structure with the base slab 20, effectively preventing relative movement between the lowest mounting base 200 and the base slab 20 when the load above it increases. This guarantees the stability of the lowest mounting base 200 installation and improves construction quality.

[0032] Specifically, when the cross-sectional width of the mounting groove 211 is greater than the cross-sectional width of the mounting part 111, a flow gap is formed between the groove wall of the mounting groove 211 along its width direction and the mounting part 111; when the cross-sectional length of the mounting groove 211 is greater than the cross-sectional length of the mounting part 111, a flow gap is formed between the groove wall of the mounting groove 211 along its length direction and the mounting part 111.

[0033] For example, the lowest mounting base 200 is provided along the entire length of the heavy concrete wall system. The lowest mounting base 200 is subjected to a large force. This arrangement can not only effectively avoid local stress concentration and reduce deformation, cracking or crushing of the lowest mounting base 200, but also enhance the stability of the support of the lowest mounting base 200 for the lowest steel plate assembly 100, and ensure the reliability of the installation of the lower steel plate assembly 100.

[0034] For example, a pre-embedded steel plate is embedded in the base plate 20, and the mounting base 200 is made of steel. The lowest mounting base 200 is welded to the steel plate on the base plate 20. In adjacent main structures 10, the adjacent upper mounting base 200 is welded to the adjacent lower steel plate assembly 100. Among them, the mounting bases 200 of the other layers except the lowest layer are made of solid steel blocks.

[0035] In some embodiments, reinforcing bars are provided within the casting space 220. This arrangement makes the bottom mounting base 200 a structure with an outer steel frame and an inner reinforced concrete frame, reducing the amount of steel used while ensuring the overall strength of the bottom mounting base 200 and enhancing the overall stability of the heavy concrete wall system. Furthermore, the reinforcing bars within the casting space 220 can be the reinforcing bars of the heavy concrete wall system or additional reinforcement.

[0036] Optionally, see Figure 1 In the two adjacent main structures 10, a first protrusion 310 is provided on one of the top of the lower heavy concrete layer 300 and the bottom of the upper heavy concrete layer 300, and a first groove is provided on the other of the top of the lower heavy concrete layer 300 and the bottom of the upper heavy concrete layer 300. The first protrusion 310 can be embedded in the first groove. This arrangement makes the interface between the two adjacent heavy concrete layers 300 have an interlocking shape, that is, the interface between the two adjacent heavy concrete layers 300 is not a plane, thereby effectively preventing radiation from radiating outward from the interface and further improving the radiation protection effect.

[0037] In this embodiment, see Figure 1 In one embodiment, the first protrusion 310 is disposed on the top of the adjacent lower heavy concrete layer 300, and the first groove is disposed on the bottom of the adjacent upper heavy concrete layer 300; in another embodiment, the first protrusion 310 is disposed on the bottom of the adjacent upper heavy concrete layer 300, and the first groove is disposed on the top of the adjacent lower heavy concrete layer 300.

[0038] See Figure 1 A second protrusion 21 is provided on the bottom of the lowest heavy concrete layer 300 and on one of the base plate 20, and a second groove is provided on the other of the bottom of the lowest heavy concrete layer 300 and on the base plate 20. The second protrusion 21 can be embedded in the second groove. This arrangement makes the interface between the lowest heavy concrete layer 300 and the base plate 20 have an interlocking shape, that is, the interface between the lowest heavy concrete layer 300 and the base plate 20 is not flat, thereby effectively preventing radiation from radiating outward from the interface and further improving the radiation protection effect.

[0039] In this embodiment, see Figure 1 The second protrusion 21 is disposed on the bottom plate 20, and the second groove is disposed on the bottom of the lower heavy concrete layer 300; in other embodiments, the second protrusion 21 is disposed on the bottom of the lower heavy concrete layer 300, and the second groove is disposed on the bottom plate 20.

[0040] In some embodiments, see Figure 1 A protective top plate 40 is provided above the uppermost main structure 10. A third protrusion 320 is provided on the top of the uppermost heavy concrete layer 300, and a third groove is provided on the bottom surface of the protective top plate 40. The third protrusion 320 can be embedded in the third groove. This arrangement makes the interface between the uppermost heavy concrete layer 300 and the protective top plate 40 have an interlocking shape, that is, the interface between the uppermost heavy concrete layer 300 and the protective top plate 40 is not flat, thereby effectively preventing radiation from radiating outward from the interface and further improving the radiation protection effect.

[0041] Optionally, see Figure 1 and Figure 4 Metal isolation plates 400 are installed at the interface between two adjacent heavy concrete layers 300 in the vertical direction and at the interface between the bottom heavy concrete layer 300 and the base plate 20. The metal isolation plates 400 are used to isolate radiation in order to further prevent the radiation of rays outward and improve the overall radiation protection effect.

[0042] For example, the metal separator 400 is made of metal steel mesh.

[0043] In some embodiments, a metal isolation plate 400 is also provided at the interface between the uppermost heavy concrete layer 300 and the protective top plate 40.

[0044] Optionally, see Figure 1 and Figure 3 The first side of the sub-steel plate 110 is provided with a plurality of first connecting parts 112 arranged in a matrix, and the second side of the sub-steel plate 110 is provided with a plurality of first connecting grooves 113. The plurality of first connecting grooves 113 correspond one-to-one with the plurality of first connecting parts 112, and any first connecting part 112 of the sub-steel plate 110 can be inserted into the corresponding first connecting groove 113 of the adjacent sub-steel plate 110. This arrangement allows the adjacent two sub-steel plates 110 to be connected by a mortise and tenon structure. On the one hand, the interlocking mortise and tenon has a guiding function, which allows the two sub-steel plates 110 to be quickly aligned and limited when spliced, reducing misalignment and deviation, and facilitating on-site assembly and construction. On the other hand, the mortise and tenon structure increases the contact area and force transmission interface between the two adjacent sub-steel plates 110, which allows the two adjacent sub-steel plates 110 to better transmit pressure, shear force and bending moment, thereby improving the overall integrity of the steel plate assembly 100.

[0045] The first side and the second side are the two sides of the sub-steel plate 110 along its thickness direction, respectively.

[0046] In some embodiments, the side of the outermost sub-steel plate 110 facing away from the adjacent sub-steel plate 110 may not have the first connecting part 112 or the first connecting groove 113, so that the contact surface between the outermost sub-steel plate 110 and the heavy concrete layer 300 can remain flat, the sub-steel plate 110 and the heavy concrete can fit tightly and bond effectively, effectively avoiding local voids and separation, ensuring that the two can deform together and bear force together, thereby improving the overall load-bearing capacity of the main structure 10.

[0047] In some embodiments, see Figure 3 and Figure 5One of the walls of the first connecting part 112 and the first connecting groove 113 is provided with a guide groove extending along the thickness direction of the sub-steel plate 110, and the other of the walls of the first connecting part 112 and the first connecting groove 113 is provided with a guide part 114, which is slidably embedded in the guide groove. When the first connecting part 112 is inserted into the first connecting groove 113, the guide part 114 can enter the guide groove and slide along the extension direction of the guide groove. The guide part 114 and the guide groove together guide the direction of insertion of the first connecting part 112 into the first connecting groove 113, so that the first connecting part 112 can be quickly and accurately inserted into the first connecting groove 113. This helps to reduce the connection difficulty of the two sub-steel plates 110, improve the connection accuracy of the two sub-steel plates 110, and speed up the construction efficiency of the two sub-steel plates 110.

[0048] In this embodiment, see Figure 3 and Figure 5 In one embodiment, the guide portion 114 is disposed on the wall of the first connecting groove 113, and the guide groove is disposed on the first connecting portion 112; in another embodiment, the guide portion 114 is disposed on the first connecting portion 112, and the guide groove is disposed on the wall of the first connecting groove 113.

[0049] Optionally, see Figure 1 , Figure 4 and Figure 6 The mounting base 200 is provided with a feature extending along the main structure 10 ( Figure 4 Multiple through holes 230 are arranged at intervals in the Y direction of the main structure 10. The through holes 230 extend along the thickness direction of the main structure 10, and the tie bolts can pass through any one of the through holes 230. The through holes 230 are designed so that the tie bolts can pass through the mounting base 200 smoothly without damaging the mounting base 200.

[0050] Specifically, the number of perforations 230 is determined based on the number of tie bolts 50, which in turn is determined based on the load-bearing capacity of the template.

[0051] Example 2 like Figures 1 to 16 As shown, this embodiment provides a construction method for an internal steel plate reinforced concrete wall system, applicable to the internal steel plate reinforced concrete wall system of Embodiment 1, including the following steps: S1, see reference Figure 8 The mounting base 200 of the lowest main structure 10 is installed on the base plate 20, and the multiple sub-steel plates 110 of the lowest main structure 10 are installed on the corresponding mounting bases 200.

[0052] In some embodiments, the following steps are included before step S1: S0. Determine the number of sub-steel plates 110 in each steel plate assembly 100 based on the specific construction conditions on site, the total weight of the steel plate assembly 100, and the lifting weight of the hoisting equipment 30.

[0053] In this embodiment, step S1 specifically includes the following steps: S11. Cast the base plate 20 and embed a pre-embedded steel plate on the top surface of the base plate 20; S12. Weld the bottom mounting base 200 to the embedded steel plate on the base plate 20. S13. Using the hoisting equipment 30, the multiple sub-steel plates 110 of the lowest layer steel plate assembly 100 are hoisted one by one to the multiple mounting positions 210 of the lowest layer mounting base 200. The sub-steel plates 110 are lowered using the hoisting equipment 30, and the mounting part 111 of the sub-steel plate 110 is inserted into the corresponding mounting groove 211. When connecting the hoisted sub-steel plate 110 with the sub-steel plate 110 that has been installed in place, the first connecting part 112 of the sub-steel plate 110 is inserted into the corresponding first connecting groove 113.

[0054] Specifically, during the installation of the sub-steel plate 110, it is necessary to ensure the verticality of the sub-steel plate 110 so that the two adjacent sub-steel plates 110 can fit tightly together, avoiding gaps between the two adjacent sub-steel plates 110 that would affect the shielding effect.

[0055] For example, the lifting equipment 30 uses an existing gantry crane or hoist. In other embodiments, see [reference needed]. Figure 9 The hoisting equipment 30 includes a support base 31, a support truss 32, and several hoisting components 33. The support base 31 can be installed on the base plate 20, the support truss 32 is disposed on top of the support base 31, and the hoisting components 33 are slidably disposed on the support truss 32. The hoisting components 33 are used to hoist the sub-steel plate 110. When the hoisting components 33 slide relative to the support truss 32, the hoisting components 33 drive the sub-steel plate 110 to move towards the mounting base 200.

[0056] S2, see reference Figure 10 Support templates are installed on both sides of the bottom steel plate assembly 100 along its thickness direction, and multiple tie bolts 50 are installed on the upper and lower sides of the bottom steel plate assembly 100. The tie bolts 50 located below the bottom steel plate assembly 100 pass through the bottom mounting base 200 and the two support templates, and the tie bolts 50 located above the bottom steel plate assembly 100 pass through the two support templates.

[0057] In this embodiment, step S2 specifically includes the following steps: S21. Tie steel mesh 60 on both sides of the bottom steel plate assembly 100 along its thickness direction; S22.

[0071] When the steel plate assembly 100 is long, it is also difficult to lift and move each sub-steel plate 110. This embodiment can further reduce the lifting weight requirements of the lifting equipment 30, reduce the difficulty of construction on each floor, and ensure the accuracy of construction on each floor.
