Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of reinforced concrete reinforcement, in particular, relates to a method and device for three-dimensional reinforcement of thin structures in a special-shaped body. BACKGROUND

[0002] In the field of metallurgy, many reinforced concrete foundation structures have complex shapes, large changes in foundation elevation and depth, and cavities inside the reinforced concrete. The irregular heavy load borne by the foundation (reinforced concrete placed in the foundation pit) includes vertical force, overturning moment, torsional moment, etc. This kind of reinforced concrete structure is collectively referred to as a special-shaped body.

[0003] In the process of overall reinforcement of the special-shaped body, the special-shaped body is usually regarded as an overall thick structure (so-called post-structure, i.e. a partial structure with a cross-sectional size greater than 400 mm). However, due to the existence of many local structures such as foundation pits, basements, pipe galleries, roof plates, connecting plates, etc. in the special-shaped body, there are also a certain amount of local thin-walled or thin-plate structures, referred to as local thin structures. The cross-sectional shape of the thin structure is quite different from that of the post-structure. If it is considered as an overall thick structure for unified consideration, i.e. the steel bar diameter, spacing and reinforcement ratio suitable for thick structures are adopted during reinforcement, it is not conducive to the structure itself and will cause waste of steel and is not conducive to the control of project cost for the thin structure due to its high reinforcement ratio and steel bar diameter. Therefore, when three-dimensionally reinforcing the special-shaped body, if the surface reinforcement method is used, after completing the three-dimensional reinforcement of the overall thick structure, all the surfaces corresponding to the thin structure need to be manually selected and modified to make the surface reinforcement suitable for the thin structure. However, due to the large number of surfaces involved in the thin structure, a large amount of manual selection and modification operation inevitably leads to omission or error, and is time-consuming and inefficient. Therefore, a suitable method for quickly three-dimensionally reinforcing the thin structure needs to be developed and applied to the three-dimensional reinforcement of the special-shaped body containing the thin structure.

[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0058] Many types of concrete foundation structures have complex shapes, large changes in elevation and depth, and cavities inside. The heavy load borne by the concrete foundation is also uneven. Such concrete foundation structures are collectively referred to as special-shaped bodies. In the process of overall reinforcement of special-shaped bodies, the special-shaped bodies are usually regarded as overall thick structures. However, due to the existence of many local structures such as foundation pits, basements, pipe galleries, roof plates, connecting plates, etc., there are also a certain amount of local thin-walled or thin-plate structures, which are referred to as local thin structures. The cross-sectional morphology of thin structures and post-structures is quite different. If they are considered as overall thick structures for unified consideration, i.e., the steel bar diameter, spacing and reinforcement ratio suitable for thick structures are used for reinforcement, it is not conducive to the structure itself for thin structures due to the high reinforcement ratio and steel bar diameter, and it will cause waste of steel and be not conducive to the control of project cost.

[0059] Based on the above problems, the present application provides a three-dimensional reinforcement method for special-shaped body thin structures, as shown in Figure 1 The method comprises the following steps:

[0060] S101: Positioning a three-dimensional model of a concrete structure and determining the types and sizes of surfaces and the sizes of sections of the concrete structure. The types of surfaces include: upper surface, lower surface, side wall and side surface.

[0061] After the three-dimensional reinforcement software loads the model of the special-shaped body, the special-shaped body is displayed in the three-dimensional reinforcement software and spatially positioned. In a specific embodiment, as shown in Figure 13As shown, spatial positioning of irregularly shaped structures includes determining their center and vertical spatial relationships. For example, for concrete irregularly shaped structures used in infrastructure construction, which are typically placed in a foundation pit, the placement of the irregularly shaped structure (foundation) in the pit determines its burial status—which part is exposed above the soil surface and which part is buried in the pit—and an XYZ coordinate system is established to determine the position of the Z-axis 0 line (in this example, the 0 line is the ground level). After positioning, the type of each surface of the irregularly shaped structure is determined, and the dimensions of the cross-section of each structure within the irregularly shaped structure are also determined.

[0062] S102: Determine the thin structure based on the dimensions of each section.

[0063] Based on the dimensions of each cross-section determined in S101, when the shorter side of a cross-section is less than a preset threshold, the structure containing this cross-section is considered a thin structure. In practice, the threshold is typically 400 mm.

[0064] In one specific embodiment, for example, if the cross-section (section) of a structure is a rectangle of 300mm × 500mm, then its shorter side is 300mm, which is less than the threshold of 400mm for thin structures, and thus the structure is a thin structure.

[0065] S103: Based on the dimensions of the upper surface, the dimensions of the lower surface, and the thin structure, the thin structure is classified into different levels and parameter-driven surface reinforcement is performed to generate the three-dimensional reinforcement of the thin structure in the irregular body.

[0066] Based on the dimensions of the upper and lower surfaces and the thin structure determined in S101, the reinforcement diagram of the concrete structure is generated. For the thick structure, the integral reinforcement method is adopted, while for the thin structure, the individual reinforcement is adopted.

[0067] like Figure 4A The alien shape shown Figure 4B The cross-sectional view of the irregular body from the front view direction shows the thin and thick structures. The thin structure 3 has a main surface 1 and an end surface 2 of 200mm, which is less than the threshold of 400mm. The overall thick structure 4 has a thickness greater than the threshold. The thickness of the thin structure 6 and the side surface 7 of the thin structure is 300mm, which is less than the threshold. The thickness of the thin structure 5 is 400mm, which is equal to the threshold, and it is also a thin structure.

[0068] In a specific embodiment, the thin structure with a thickness less than 400 mm is further divided, and the thickness level range of each thickness interval thin structure is determined. The thickness can be divided into the following levels: less than 100 mm, between 100 mm and 150 mm, between 150 mm and 200 mm, between 200 mm and 250 mm, between 250 mm and 300 mm, and between 350 mm and 400 mm. The present application is not limited thereto. Different reinforcement schemes are adopted for different thickness levels for configuration. In actual process, the reinforcement parameters of thin structures of various thickness levels are shown in Table 1:

[0069] Table 1

[0070]

[0071] Figure 1 The execution subject of the method shown can be a server, a PC, or a mobile terminal. The method first rapidly determines the thin structure by determining the type of each surface of the irregular body and the size of each section, and then quickly reinforces the irregular body based on the overall thick structure and the thin structure. The functions of rapidly determining and dividing the types of each surface of the irregular body and the structure type are realized.

[0072] In an embodiment, as shown in Figure 2 , determining the type of each surface of the concrete structure includes:

[0073] S201: determining that the outer periphery of the concrete structure above the ground and / or the side surface of the concrete structure below the ground and in contact with the foundation pit is the side surface of the concrete structure.

[0074] Through the positioning step of S101, the outermost periphery of the structure above the 0 line and the side surface A in contact with the soil below the 0 line are determined as the side surface A of the concrete structure.

[0075] In a specific embodiment, as shown in Figure 5 , the A surface in

[0076] S202: determining the cavity in the concrete structure and taking the side wall of the cavity as the side wall of the concrete structure.

[0077] The cavity in the concrete structure is automatically positioned, and the side wall B of the cavity is the side wall B of the concrete structure.

[0078] In a specific embodiment, as shown in Figure 6 , the profile view in the main surface direction of the irregular body in Figure 5 is shown, in which B is the side wall B of the cavity (the side wall of the concrete structure).

[0079] S203: determining the upper surface and the lower surface of the concrete structure.

[0080] The three-dimensional reinforcement software judges the upper surface and the lower surface of the concrete structure, and the size of the upper surface and the lower surface, so as to determine the main stress direction of the special-shaped body.

[0081] In an embodiment, as shown in Figure 3 The three-dimensional reinforcement method of the thin structure further includes:

[0082] S301: Establish a mapping relationship table of the thickness of the protective layer and the type of each surface.

[0083] The thickness of the protective layer of each surface of the special-shaped body is not consistent, and the thickness of the protective layer needs to be determined according to the type of the surface. In most cases, the thickness of the protective layer of the bottom surface is thicker than that of other surfaces. In a specific embodiment, as shown in Figure 3 An example of setting the thickness of the protective layer of the special-shaped body is shown. Before the three-dimensional reinforcement software is used to reinforce the special-shaped body, the thickness setting parameters of the protective layer of different surface types are pre-stored in the background parameter database of the three-dimensional reinforcement software. When the special-shaped body is loaded into the three-dimensional reinforcement software, the three-dimensional reinforcement software quickly determines the type of each surface of the special-shaped body according to certain rules, and a mapping relationship table of the thickness of the protective layer and the type of each surface is pre-stored in the software.

[0084] S302: Determine the thickness of the protective layer of each surface according to the type of each surface and the mapping relationship table.

[0085] In a specific embodiment, the thickness of the protective layer corresponding to different types is found from the pre-stored thickness setting parameters of the protective layer in the background parameter database according to the type of each surface. For example, the thickness of the protective layer corresponding to the bottom surface of the bottom plate is 40 mm, and the thickness of the protective layer corresponding to the top surface of the bottom plate, the side wall of the side surface, and the top surface of the top plate is 25 mm.

[0086] Meanwhile, during the specific implementation process, the technical personnel can also perform supplementary input operations on the missing environmental parameters and material information.

[0087] In an embodiment, as shown in Figure 8 According to the size of the upper surface, the size of the lower surface, and the thin structure, the surface reinforcement is driven by parameters, and the three-dimensional reinforcement of the thin structure in the special-shaped body is generated, including:

[0088] S801: Determine the main stress direction of the concrete structure according to the size of the upper surface and the size of the lower surface.

[0089] First, the type of each surface is determined, then the upper surface and the lower surface are found, and then the size of the upper surface and the lower surface is determined. The direction of the shorter side in the upper surface and the lower surface is the main stress direction.

[0090] S802: generating three-dimensional reinforcement of the thin structure in the special-shaped body according to the parameter-driven surface reinforcement of the main stress direction and the thin structure.

[0091] Step S802 proposes a simple and fast method for determining the main stress direction of the special-shaped body, which determines the main stress direction of the special-shaped body through the shape of the upper and lower surfaces, realizes the fast determination of the main stress direction of the special-shaped body, and determines the distribution of the inner and outer layers of the steel bars according to the main stress direction, and does not need to manually input the reinforcement scheme suitable for the thin structure each time.

[0092] In an embodiment, the main stress direction of the concrete structure is determined according to the size of the upper surface and the size of the lower surface, comprising:

[0093] The size of the upper surface and the size of the lower surface are compared, and the direction with the shorter size is determined as the main stress direction of the concrete structure.

[0094] In a specific embodiment, the three-dimensional structure of the concrete special-shaped body is as shown in Figure 5 The surface structure of the special-shaped body is complex, has many turning surfaces, and also contains a cavity structure. The top view of the special-shaped body is as shown in Figure 7 Figure 7 In the embodiment, the length of the X direction is longer than the length of the Y direction as a whole, and the length of the Y direction is shorter, so the Y direction is the main stress direction of the special-shaped body.

[0095] In an embodiment, the thin structure is determined according to the size of each section, comprising:

[0096] The thin structure is determined according to the size relationship between each section and the preset value.

[0097] In a specific embodiment, the technician classifies the structure with a thickness less than or equal to 400 mm as a thin structure according to experience or regulation, and if the size of the shorter side in the section is less than or equal to 400 mm, the mechanism to which the section belongs is a thin structure. Specifically, the thin structure is further divided to determine the thickness level range of each thickness interval thin structure. The thickness can be divided into the following levels: less than 100 mm, between 100 mm and 150 mm, between 150 mm and 200 mm, between 200 mm and 250 mm, between 250 mm and 300 mm, and between 350 mm and 400 mm. The present application is not limited thereto.

[0098] After the setting is completed, the software background program automatically completes the reinforcement setting of all surfaces of the special-shaped body. After completion, the three-dimensional reinforcement software continues to execute the parameter-driven three-dimensional reinforcement function to complete the three-dimensional reinforcement. In the reinforcement process and any subsequent operation link, manual reinforcement setting is not required.

[0099] ​Based on the same inventive concept, the embodiment of the present application further provides a device for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body, which can be used to implement the method described in the above embodiment, as described in the following embodiment. Since the device for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body solves the problem by the similar principle as the method for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body, the implementation of the device for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body can be referred to the implementation of the method for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body, and the repeated parts will not be described herein. The term "unit" or "module" used below can be a combination of software and / or hardware that implements a predetermined function. Although the system described in the following embodiment is preferably implemented in software, the implementation of hardware or a combination of software and hardware is also possible and conceived.

[0100] As shown in Figure 9 , the present application provides a device for parameter-driven three-dimensional reinforcement of a thin structure in a special-shaped body, comprising:

[0101] a positioning unit 901 configured to position a three-dimensional model of the concrete structure and determine types and sizes of surfaces and sizes of sections of the concrete structure, the types of the surfaces including an upper surface, a lower surface, a side wall and a side surface;

[0103] a reinforcement generating unit 903 configured to generate a reinforcement map of the concrete structure according to the sizes of the upper surface, the sizes of the lower surface and the thin structure.

[0104] In an embodiment, as shown in Figure 10 , the positioning unit 901 comprises:

[0105] a side surface determining module 1001 configured to determine the side surface of the concrete structure above the ground and / or the side surface of the concrete structure below the ground and in contact with the foundation pit as the side surface of the concrete structure;

[0106] a side wall determining module 1002 configured to determine the cavity in the concrete structure and determine the side wall of the cavity as the side wall of the concrete structure;

[0107] a surface determining module 1003 configured to determine the upper surface and the lower surface of the concrete structure.

[0108] In an embodiment, the device for three-dimensional reinforcement of a thin structure in a special-shaped body further comprises:

[0109] a mapping relationship table generating unit configured to establish a mapping relationship table between the thickness of the protective layer and the types of the surfaces;

[0110] The protection layer determination unit is configured to determine the protection layer thickness of each surface according to the type of each surface and the mapping relationship table.

[0111] In an embodiment, as shown in FIG. 9, the reinforcement generation unit 903 includes: Figure 11

[0112] The main stress direction determination module 1101 is configured to determine the main stress direction of the concrete structure according to the size of the upper surface and the size of the lower surface.

[0113] The reinforcement map determination module 1102 is configured to generate the three-dimensional reinforcement of the thin structure in the special-shaped body according to the main stress direction and the surface reinforcement driven by parameters of the thin structure.

[0114] In an embodiment, the main stress direction determination module 1101 includes:

[0115] The comparison module is configured to compare the size of the upper surface and the size of the lower surface, and determine the direction with the shorter size as the main stress direction of the concrete structure.

[0116] In an embodiment, the thin structure determination unit 902 includes:

[0117] The size comparison module is configured to determine the thin structure according to the size relationship between the size of each section and a preset value.

[0118] The key to implementing the method is the determination of the reinforcement parameter scheme for each thickness level of the thin structure and how to smoothly extract and select in the design. By referring to the experience accumulated from years of engineering project design, the reinforcement scheme under the guidance of the optimized reinforcement ratio for each thickness level is summarized, and several reinforcement optimization parameter schemes suitable for each thickness level of the thin structure are provided for selection. As known, if the reinforcement ratio is too small, the structure cannot meet the bearing capacity requirement; if the reinforcement ratio is too large, the structure may be brittlely damaged under overload. The optimized reinforcement parameter scheme combines the suitable reinforcement diameter and spacing, avoids the too large or too small reinforcement ratio, and is a reinforcement scheme that can maximize the performance of the reinforcement and concrete material and take into account the economic indicators. When reinforcing the thin structure, the designer selects the parameter scheme suitable for the current design from the optimization scheme with the help of the operation interface provided by the software. The factors for selecting the optimized reinforcement parameter scheme include the maximum integration of the reinforcement of the thin structure and the thick structure, the overall requirement of the project design, the demand of the owner, etc.

[0119] ​The method is an automatic and fast three-dimensional reinforcement method for all thin structures in the special-shaped body based on the parameter-driven surface reinforcement. In the software development process, the optimized reinforcement parameter schemes of the thin structures of various thickness levels which have been verified are stored in the background database of the software. The optimized reinforcement data schemes not only include the parameter schemes of the main surface of the thin structure, but also include the parameter schemes of the end surface and the side surface distribution steel. In the software development, the determination conditions of the thin structure and the division conditions of the thickness level are preset. Before the three-dimensional reinforcement of the special-shaped body, the software determines by scanning the structure shape, and extracts all the surfaces of the thin wall and the thin plate structure of each thickness level in the special-shaped body and classifies them. The main surface, the end surface and the side surface of the thin structure are determined and extracted separately. Next, the software provides an interface for the designer to select the reinforcement parameter scheme suitable for the current design from the optimized reinforcement parameter schemes of various thickness levels, that is, to perform the parameter-driven surface reinforcement on the main surface, the side surface and the end surface of the thin structure. Next, the reinforcement of the adjacent surfaces of the thin structure is automatically fused according to the rules, so as to generate the three-dimensional reinforcement of all the thin structures in the special-shaped body.

[0120] The method of automatically determining the structure form, automatically dividing the thickness level, automatically extracting various types of surfaces in the thin structure, automatically extracting the parameter reinforcement optimization scheme suitable for the thin structure for selection, and performing the three-dimensional surface reinforcement of the thin structure by parameters is a method of fully utilizing the algorithm and rules for automatic reinforcement, and is a supplement and improvement of the special-shaped body surface reinforcement method. The method is applied to the design process of using the reinforcement software to perform the three-dimensional reinforcement of the special-shaped body, and can improve the efficiency of the three-dimensional reinforcement of the special-shaped body and provide accurate and optimized reinforcement results for the designer.

[0121] The application is applied to the secondary development of the PPST three-dimensional reinforcement software in the Bentley three-dimensional collaborative design platform, and is used in the three-dimensional design of the concrete structure, can significantly improve the efficiency of the three-dimensional reinforcement of the special-shaped body by using the software, and further improve the efficiency of the BIM three-dimensional collaborative design in the engineering project design. And can be used for standardizing the reinforcement design of the concrete structure, and promoting the use of the BIM full life cycle management in the engineering project design, construction and operation stage.
