[0048] See also Figure 1 , Figure 1 FIG. 1 is a schematic diagram of an application environment of a method for obtaining a block solution in an embodiment of the present invention. The method for obtaining a block solution provided in an embodiment of the present invention can be applied in the following embodiments: Figure 1 In an application environment, a client communicates with a server through a network.

[0049] The server obtains a bending moment envelope diagram of the prefabricated structure through the client, obtains an inflection point in the bending moment envelope diagram, selects the position of the inflection point as a transverse seam division position, and obtains the number of transverse seam division positions;

[0050] According to the number of transverse seam division positions, a maximum number of modules is obtained, and when the total number of modules on the prefabricated structure is not greater than the maximum number of modules, a block division scheme corresponding to the total number of modules is obtained;

[0057] The device running the server is referred to as the server device.

[0058] Among them, client devices include but are not limited to smartphones, personal computers, Internet of Vehicles terminals, tablets and portable wearable devices.

[0059] The server device may be implemented by an independent server or a server cluster composed of multiple servers. The present invention is described in detail below through specific embodiments. Figure 2 , Figure 2 A flowchart of a method for obtaining a block solution provided by an embodiment of the present invention includes the following steps:

[0060] S21, obtaining a bending moment envelope diagram of the prefabricated structure, obtaining an inflection point in the bending moment envelope diagram, selecting the position of the inflection point as a transverse seam division position, and obtaining the number of transverse seam division positions;

[0061] Among them, prefabricated structures include but are not limited to solid permanent and temporary prefabricated structures and cavity permanent and temporary prefabricated structures.

[0062] Among them, the solid permanent and temporary prefabricated structure refers to a structure formed by organically combining permanent structure and temporary structure by using solid prefabricated components in prefabricated buildings.

[0063] Among them, the cavity permanent and temporary combined prefabricated structure refers to a structure formed by organically combining permanent structure and temporary structure by using cavity prefabricated components in prefabricated buildings.

[0064] Among them, the moment envelope diagram is a moment diagram formed when various loads act on the prefabricated structure and the most unfavorable situation is taken at each position. The moment envelope diagram reflects the relationship between the maximum moment and the axis of the prefabricated structure under different load combinations.

[0065] Among them, the transverse seam division position is the division position of the transverse seam. The transverse seam refers to the seam reserved or formed in the horizontal direction between different prefabricated structural blocks in the prefabricated structure. The design and construction of the transverse seam are crucial to the overall performance of the prefabricated structure. The main function of the transverse seam is to allow the prefabricated structure to produce a certain deformation under factors such as temperature changes and loads, thereby avoiding structural damage caused by internal stress concentration. By reasonably setting the transverse seam, it can be ensured that the prefabricated structure can effectively disperse and release stress when subjected to various external forces, thereby improving the overall stability and safety of the structure.

[0066] S22, obtaining a maximum number of modules according to the number of transverse seam division positions, and when the total number of modules on the prefabricated structure is not greater than the maximum number of modules, obtaining a block division scheme corresponding to the total number of modules;

[0067] The block scheme is a scheme that divides the prefabricated structure into multiple prefabricated structure blocks. The purpose of the block scheme is to simplify the manufacturing process of the prefabricated structure, reduce the difficulty of transportation, and improve the efficiency of installation.

[0068] The total number of modules refers to the total number of single blocks of the prefabricated structure.

[0069] The maximum number of modules is the maximum number of single blocks of the prefabricated structure.

[0070] Among them, the prefabricated structure block is a single module in the prefabricated structure.

[0071] Among them, the individual modules in the prefabricated structure are components of the entire prefabricated structure. The individual modules in the prefabricated structure are usually prefabricated in the factory, which can greatly improve production efficiency and shorten the construction period.

[0072] Wherein, the maximum number of modules is obtained according to the number of transverse seam division positions, and when the total number of modules on the prefabricated structure is not greater than the maximum number of modules, a block division scheme corresponding to the total number of modules is obtained, including:

[0073] Adding the number of transverse seam division positions and 1, the maximum number of modules of the prefabricated structure is obtained;

[0074] When the total number of modules on the prefabricated structure is not greater than the maximum number of modules, a block division scheme corresponding to the total number of modules is obtained.

[0075] When the total number of modules on the prefabricated structure is not greater than the maximum number of modules, a recursive algorithm is used to obtain a block division scheme corresponding to the total number of modules.

[0076] Among them, a recursive algorithm is an algorithm that solves a problem by directly or indirectly calling its own functions or methods.

[0077] For the sake of illustration, an example is given below:

[0078] For example, the number of potential transverse seam division positions on the prefabricated structure is 6, and the recursive algorithm sets the maximum number of modules on the prefabricated structure to 7.

[0079] When the total number of modules on the prefabricated structure is 1, and 1 is not greater than 7, a recursive algorithm is used to obtain a block scheme formed when the total number of modules of the prefabricated structure is 1, and the block schemes formed when the total number of modules of the prefabricated structure is 1 are formed into a scheme group P1;

[0080] When the total number of modules on the prefabricated structure is 2, and 2 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block scheme formed when the total number of modules of the prefabricated structure is 2 is formed into a scheme group P2;

[0081] When the total number of modules on the prefabricated structure is 3, and 3 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block scheme formed when the total number of modules of the prefabricated structure is 2 is formed into a scheme group cubic meter;

[0082] When the total number of modules on the prefabricated structure is 4, and 4 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block scheme formed when the total number of modules of the prefabricated structure is 2 is formed into a scheme group P4;

[0083] When the total number of modules on the prefabricated structure is 5, and 5 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block scheme formed when the total number of modules of the prefabricated structure is 2 is formed into a scheme group P5;

[0084] When the total number of modules on the prefabricated structure is 6, and 6 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block scheme formed when the total number of modules of the prefabricated structure is 2 is formed into a scheme group P6;

[0085] When the total number of modules on the prefabricated structure is 7 and 7 is not greater than 7, a recursive algorithm is used to obtain the block scheme formed when the total number of modules of the prefabricated structure is 2, and the block schemes formed when the total number of modules of the prefabricated structure is 2 are formed into scheme group P7.

[0086] P1, P2, P, P4, P5, P6, and P7 are grouped into a solution group P. The solution group P has a block solution corresponding to each total number of modules.

[0087] S23, obtaining the vertical length, longitudinal length, thickness, and cavity ratio of a single block of the prefabricated structure in each block division scheme, wherein the single block of the prefabricated structure is a single module in the prefabricated structure;

[0088] Among them, the vertical length of the prefabricated structure single block refers to the size of the prefabricated structure single block in the vertical direction, that is, the height of the prefabricated structure single block from the bottom to the top.

[0089] The longitudinal length of the assembled structure monoblock refers to the extension of the assembled structure monoblock in the direction of the long axis, that is, the length of the assembled structure monoblock.

[0090] The thickness of a single block of the prefabricated structure refers to the dimension of the single block of the prefabricated structure perpendicular to the main force direction.

[0091] The cavity ratio of a single block of a prefabricated structure refers to the ratio of the volume occupied by the cavity to the total volume of the single block of the prefabricated structure.

[0092] S24, generating a model according to the vertical length, longitudinal length, thickness, cavity ratio and weight of the single block of the prefabricated structure in each block scheme, and generating the weight of the single block of the prefabricated structure in each block scheme;

[0093] The method of generating a model according to the vertical length, longitudinal length, thickness, cavity ratio and weight of the assembled structure monoblock in each block scheme to generate the weight of the assembled structure monoblock in each block scheme includes:

[0094] Get the weight generation model in the preset file;

[0095] A model is generated according to the vertical length, longitudinal length, thickness, cavity ratio and weight of a single block of the prefabricated structure in each block scheme, and the weight of the single block of the prefabricated structure in each block scheme is generated.

[0096] Exemplarily, the weight generation model is:

[0097] ;

[0098] is the weight of a single block of the prefabricated structure in the bth block scheme;

[0099] ρ is the density of the fabricated structure;

[0100] is the longitudinal length of the single block of the prefabricated structure in the bth block scheme;

[0101] is the vertical length of the single block of the prefabricated structure in the bth block scheme;

[0102] is the thickness of a single block of the prefabricated structure in the bth block scheme;

[0103] is the cavity ratio of the prefabricated structure.

[0104] Among them, the weight generation model is a generation model of weight.

[0105] S25, using preset constraints, screening the vertical length, longitudinal length, thickness, cavity ratio of the assembled structure monoblock in each block scheme and the weight of the assembled structure monoblock in each block scheme to obtain a block scheme that meets the constraints;

[0106] Exemplarily, the constraints are:

[0107] ;

[0108] ;

[0109] ;

[0110] ;

[0111] is the vertical length of the single block of the prefabricated structure in the bth block scheme; is the first limit;

[0112] is the longitudinal length of the single block of the prefabricated structure in the bth block scheme; is the second limit;

[0113] is the thickness of a single block of the prefabricated structure in the bth block scheme; is the third limit;

[0114] is the weight length of the single block of the prefabricated structure in the bth block scheme; is the fourth limit.

[0115] The first limit value, the second limit value, the third limit value, and the fourth limit value are different limit values. The first limit value, the second limit value, the third limit value, and the fourth limit value can be set according to local transportation management conditions and are not limited here.

[0116] S26, selecting a block scheme that meets the constraint conditions as a preferred block scheme, obtaining the construction carbon emissions corresponding to each preferred block scheme, and selecting the preferred block scheme with the smallest construction carbon emissions as the optimal block scheme for the prefabricated structure.

[0117] Among them, construction carbon emissions refer to the carbon emissions during the construction process, which includes the production stage, transportation stage and construction stage.

[0118] Among them, selecting the preferred block scheme with the smallest construction carbon emissions as the optimal block scheme for the prefabricated structure not only reduces the operating costs of the enterprise, but also promotes the research and development and application of clean energy and low-carbon technologies, promotes the optimization and upgrading of the economic structure, and achieves a win-win situation of economic benefits and environmental protection.

[0119] For the sake of explanation, we take the project as an example and describe it in detail as follows:

[0120] The station in a certain city adopts a prefabricated structure. The station has two floors, with cast-in-place ground-connected walls at both ends and a prefabricated structure in the middle. The prefabricated structure adopts a lightweight cavity setting.

[0121] Combined with the local transportation management situation of the city, according to the block plan acquisition method of the prefabricated structure,

[0122] A recursive algorithm was used to calculate all the block solutions that met the mechanical properties, a total of 100. The width of each block solution was iterated through a sorting algorithm. Finally, the block solutions were screened according to the constraints, and 3 block solutions whose block lengths were greater than the transportation length limit were finally removed, resulting in 70 block solutions that met the constraints.

[0123] Carbon emissions were calculated for 70 block schemes, and it was found that when the width of the single-ring prefabricated structure is U1 meter, and it is vertically divided into three blocks with each block being U2 meters, U2 meters, and U3 meters in length, the scheme has the lowest construction carbon emissions, achieving the optimal mechanical properties and construction carbon emissions of the prefabricated structure blocks.

[0124] By calculating and analyzing the construction carbon emissions of all feasible block schemes, it can be seen that the above optimal block scheme reduces the construction carbon emissions and can ensure the bearing capacity of the structure at the same time, which confirms the rationality and effectiveness of the block decision method proposed in the present invention.

[0125] Wherein, after selecting the block scheme that meets the constraint condition as the preferred block scheme, obtaining the construction carbon emission corresponding to each preferred block scheme, and selecting the preferred block scheme with the smallest construction carbon emission as the optimal block scheme of the prefabricated structure, the block scheme acquisition method includes:

[0126] A save instruction is obtained, the save instruction is executed, the optimal block scheme is saved in a preset storage area, and when a display instruction is received, the optimal block scheme is read from the storage area and the optimal block scheme is displayed.

[0127] In the embodiment of the present invention, the beneficial effects are in two aspects. On the one hand, a block scheme that meets the constraint conditions is selected as a preferred block scheme, and the construction carbon emissions corresponding to each preferred block scheme are obtained. The preferred block scheme with the smallest construction carbon emissions is selected as the optimal block scheme for the prefabricated structure. Since no manual decision is required, the time for obtaining the optimal block scheme for the prefabricated structure is reduced, which is beneficial to improving the efficiency of obtaining the optimal block scheme for the prefabricated structure. On the other hand, since the optimal block scheme is automatically obtained and will not be affected by manual decision-making, it is beneficial to improve the reliability of the obtained optimal block scheme for the prefabricated structure.

[0129] S31, obtaining a data table corresponding to each block scheme;

[0130] S32, in a data table corresponding to each block scheme, obtain the vertical length, longitudinal length, thickness, and cavity ratio of a single block of the prefabricated structure in each block scheme, wherein the single block of the prefabricated structure is a single module in the prefabricated structure.

[0131] The corresponding relationship between the block scheme and the data table is one-to-one, that is, one block scheme corresponds to one data table, and different block schemes correspond to different data tables.

[0132] In an embodiment of the present invention, the vertical length, longitudinal length, thickness, and cavity ratio of the prefabricated structure block in each block scheme are obtained. By understanding the differences between the vertical length, longitudinal length, thickness, and cavity ratio of the prefabricated structure block in each block scheme and the constraints, the optimization of the production process can be guided, unnecessary waste and delays can be reduced, and the overall production efficiency can be improved.

[0135] S42, using constraint conditions, screening the vertical length, longitudinal length, thickness, cavity ratio and weight of the prefabricated structure single block in each block scheme, and obtaining a block scheme that meets the constraint conditions.

[0189] In the embodiment of the present invention, the beneficial effects are in two aspects. On the one hand, a block scheme that meets the constraint conditions is selected as a preferred block scheme, and the construction carbon emissions corresponding to each preferred block scheme are obtained.

Since no manual decision is required, the time for obtaining the optimal block scheme for the prefabricated structure is reduced, which is beneficial to improving the efficiency of obtaining the optimal block scheme for the prefabricated structure. On the other hand, since the optimal block scheme is automatically obtained and will not be affected by manual decision-making, it is beneficial to improve the reliability of the obtained optimal block scheme for the prefabricated structure.
