[0001] This application relates to the field of building construction technology, and in particular to a secondary structure bricklaying method, system, terminal and storage medium based on BIM technology. Background Technology

[0002] Currently, secondary structures in building construction projects have numerous detailed nodes. Due to the difficulty in carrying out precise design during construction, the cutting of raw materials such as masonry on the construction site is quite arbitrary, resulting in serious waste and loss.

[0003] In related technologies, well-managed and technically capable project teams typically use tools such as CAD (Computer-Aided Design) for refined secondary structural design, relying on users to manually lay out materials such as masonry blocks on a computer-generated plan. However, if changes occur during the construction of the masonry walls, manual adjustments are necessary, leading to reduced construction efficiency.

[0004] Therefore, how to achieve automatic masonry layout to overcome the shortcomings of manual masonry layout has become an urgent technical problem to be solved. Summary of the Invention

[0054] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0055] This application provides a secondary structure bricklaying method based on BIM technology, which can realize the automatic arrangement of masonry to improve bricklaying efficiency.

[0056] It is understood that BIM technology is a data-driven tool applied to engineering design, construction, and management. It integrates various project-related information through a bricklaying parameter model, and shares and transmits this information throughout the entire lifecycle of project planning, operation, and maintenance. This enables engineering technicians to correctly understand and efficiently respond to various building information, and provides a foundation for collaborative work for design teams and all parties involved in construction, including building operation units. It plays an important role in improving production efficiency, saving costs, and shortening construction periods.

[0057] The secondary structure bricklaying method based on BIM technology provided in this application embodiment can be executed by terminal devices with processing capabilities, such as computers.

[0058] The main process of the secondary structure bricklaying method based on BIM technology provided in this application embodiment is described as follows.

[0059] like Figure 1 As shown:

[0060] Step S100: Obtain the first model.

[0061] The first model is a 3D model of the wall to be tiled. It's understandable that designing the tile layout for a wall requires a corresponding building model. Therefore, before designing the tile layout, the corresponding building model can be opened using BIM software. Then, the wall that hasn't yet been tiled is selected; this selected model is the first model. Because walls belonging to secondary structures have many details, such as holes for installing doors and windows, as well as lintels and copings for doors and windows, most walls requiring tile layout are secondary structure walls.

[0062] Step S200: Construct a second model based on the first model.

[0063] The second model is a brick wall surface without pre-set holes, which are reserved for the installation of doors, windows or pipes.

[0064] In this embodiment, the second model can be a model obtained by copying and pasting a second model. To facilitate bricklaying design, the holes for installing doors, windows, and pipes need to be removed from the copied and pasted model to obtain the second model. Since the second model only contains wall information, bricklaying on it is simpler.

[0065] Step S300: Obtain user requirements.

[0066] User requirements refer to the user's specifications regarding bricklaying methods. Specific requirements may include: requirements for horizontal mortar joint width, vertical mortar joint width, wall thickness, block type, lintel height, coping height, whether the location of pre-drilled holes is adjustable, and the space available for such adjustments. Users may specify only one or more of these requirements, or none at all. User requirements can be obtained directly from the user.

[0067] Step S400: Arrange the bricks in the second model according to the user's requirements to obtain multiple preliminary brick arrangement models.

[0068] The preliminary bricklaying model is obtained by laying bricks according to the second model. Multiple preliminary bricklaying models can be obtained by using different bricklaying methods. Each preliminary bricklaying model includes a first bricklaying scheme.

[0069] Furthermore, the method for obtaining a preliminary bricklaying model from the second model can be as follows: First, it is necessary to determine the user's requirements, such as whether there are requirements for the width of horizontal mortar joints, the width of vertical mortar joints, the wall thickness, and the type of blocks. Once the user's requirements are clear, the bricklaying parameters requested by the user need to be set according to their needs. The remaining adjustable bricklaying parameters can be randomly matched to generate multiple preliminary bricklaying models. The requirement for wall thickness corresponds to the requirement for the placement of the blocks. Specific placement methods can include parallel arrangement, staggered arrangement, patterned arrangement, and mosaic arrangement, etc., and the number of blocks used varies depending on the placement method. It should be noted that some placement methods may be limited by the type of blocks. The type of block refers to the size of the blocks; different types of blocks have different sizes.

[0070] For example, assuming the user only has requirements regarding block type, and there are 3 selectable horizontal mortar joint widths, 2 selectable vertical mortar joint widths, and 2 selectable placement methods, then by adjusting the bricklaying parameters, 3 × 2 × 2 = 12 preliminary bricklaying models can be obtained. Of course, as the number of adjustable bricklaying parameters increases, the number of possible preliminary bricklaying models also increases. Once the values ​​of all bricklaying parameters are determined, these parameters can be input into the BIM software, and then the automatic bricklaying function can be used to lay bricks on the second model to obtain the preliminary bricklaying model.

[0071] Step S500: Determine the brick layout information required for the first brick layout scheme of each preliminary brick layout model based on the user requirements and hole size.

[0072] The hole dimensions refer to the dimensions of the holes required for installing doors, windows, and pipes. The bricklaying information includes at least the block type, block quantity, unit price, and quantity of custom-made blocks. It is understood that different bricklaying schemes use different block types, and each scheme may use multiple types of blocks. The block quantity is the required quantity of each type of block. The unit price is the price per block for each type. Custom-made blocks are blocks that have been cut from whole blocks. It is understood that because holes need to be pre-drilled in the wall, the blocks used around the holes are cut. Custom-made blocks require more time to prepare. Therefore, the use of custom-made blocks should be minimized.

[0073] It is worth noting that, since the location of the holes has a significant impact on the bricklaying information, before determining the bricklaying information required for the first bricklaying scheme of each preliminary bricklaying model, it is first necessary to determine whether the user accepts adjustments to the hole locations. This can be obtained by acquiring user requirements.

[0074] If the user does not accept adjustments to the hole positions, the first brick arrangement scheme included in the multiple preliminary brick arrangement models represents all feasible brick arrangement schemes. At this point, proceed directly to the next step.

[0075] Conversely, if the user accepts the adjustment of the hole's position, it means that more brick arrangement options can be obtained by adjusting the hole's position on the wall.

[0076] Specifically, first, we need to determine the adjustment range acceptable to the user. It's understandable that openings in doors, windows, and pipes can move in four directions: up, down, left, and right. In some special cases, openings in doors, windows, and pipes can only move in three of these directions. Therefore, the adjustment range includes the range that can be adjusted in each direction. This adjustment range can be obtained by gathering user feedback.

[0077] Secondly, based on the adjustment range, the location and size of the holes, multiple second-row brick schemes are determined for each preliminary brick layout model.

[0078] The second brick arrangement scheme is obtained by adjusting the first brick arrangement scheme based on the adjustment range. That is, the first brick arrangement scheme is obtained by arranging bricks in the second model according to different brick arrangement parameters, while the second brick arrangement scheme is obtained by adjusting the position of the holes in each of the first brick arrangement schemes.

[0079] Specifically, firstly, the positions of each hole in the second model are determined based on their positions in the first model. Secondly, the positional relationships between each hole and its surrounding blocks are determined. Then, the first row of bricks is adjusted according to the positional relationships between each hole and its surrounding blocks, as well as the adjustment range, to obtain the second row of bricks.

[0080] In a specific embodiment, the above process is as follows: First, the position of each hole in the first model is determined, and the same position is marked in the second model. Specifically, the holes can be identified by square frames in the second model. In the second model, the blocks that fall within the square frames are custom blocks. Thus, the number of custom blocks can be determined in this way. Furthermore, other information in the brick arrangement information of the first row of bricks can be automatically obtained from BIM software. Then, it can be understood that when the edge of the square frame corresponding to each hole just touches the edge of a certain row of bricks, the number of custom blocks can be reduced. Therefore, the minimum adjustment distance in each direction is determined based on the position of each hole. The minimum adjustment distance is the vertical distance between the edge of the hole and the nearest brick. It is important to note that it is also necessary to confirm whether the minimum adjustment distance is within the adjustment range. If the minimum adjustment distance is within the adjustment range, it can be adjusted according to the minimum adjustment distance to obtain a second row of bricks. Conversely, if the minimum adjustment distance is not within the adjustment range, it cannot be adjusted according to the corresponding direction. Through the above adjustment scheme, multiple second row of bricks can be obtained based on the first row of bricks.

[0081] Finally, the brick arrangement information for the first and second brick arrangement schemes is determined.

[0082] Understandably, when the user accepts adjustments to the hole position, both the first and second row bricklaying schemes are feasible. In this case, the quantity of custom blocks and other bricklaying information can be determined using the methods described above. However, when the user does not accept adjustments to the hole position, only the first row bricklaying scheme is feasible. Similarly, the quantity of custom blocks and other bricklaying information can be determined using the methods described above.

[0083] Step S600: Determine the optimal brick layout model based on the brick layout information to obtain the optimal brick layout scheme.

[0084] The optimal brick arrangement scheme is the best among all first-order and second-order brick arrangement schemes. A model that includes the optimal brick arrangement scheme is called the optimal brick arrangement model.

[0085] When determining the optimal bricklaying model based on bricklaying information, the optimal model can be determined based on the number of customized blocks, or on the cost of bricklaying. Alternatively, the optimal model can be determined based on one or more pieces of information from the bricklaying data, depending on actual needs.

[0086] In one specific embodiment, the optimal bricklaying scheme can be selected from all first-row and second-row bricklaying schemes, choosing the scheme with the fewest custom blocks. It is understood that the bricklaying scheme with the fewest custom blocks among all first-row and second-row bricklaying schemes may not be the optimal scheme. Therefore, it is necessary to minimize the total number of blocks while still ensuring the minimum number of custom blocks is achieved, in order to obtain the optimal bricklaying scheme.

[0087] In another specific embodiment, the brick-laying cost required for each first brick-laying scheme and the brick-laying cost required for each second brick-laying scheme can be determined based on the brick-laying information of each scheme. Then, the scheme with the lowest brick-laying cost is selected as the optimal brick-laying scheme.

[0088] Furthermore, once the optimal bricklaying scheme is determined, each block in the corresponding optimal bricklaying model is numbered so that the bricklayers can print out the bricklaying scheme and lay the bricks according to the numbered sequence.

[0089] Figure 2 This application provides a secondary structure bricklaying system based on BIM technology as one embodiment.

[0090] The secondary structure bricklaying method based on BIM technology provided in this application embodiment can be well applied to the above-mentioned scenarios and can realize the automatic arrangement of masonry to improve bricklaying efficiency.

[0092] The first acquisition module 21 is used to acquire the first model, which is a three-dimensional model of the wall surface to be laid with bricks.

[0093] The construction module 22 is used to construct a second model based on the first model. The second model is a brick wall surface to be laid without pre-set holes, and the holes are used to install doors, windows or pipes.

[0094] The second acquisition module 23 is used to acquire user requirements, which include requirements for the width of horizontal mortar joints, requirements for the width of vertical mortar joints, requirements for wall thickness, requirements for block type, requirements for lintel height, requirements for coping height, whether the position of the reserved hole is adjustable, and the space where the position of the reserved hole is adjustable.

[0095] The brick-laying module 24 is used to lay bricks in the second model according to the user's requirements to obtain multiple preliminary brick-laying models, each of which includes a first brick-laying scheme.

[0096] The first determining module 25 is used to determine the brick arrangement information required for the first brick arrangement scheme of each preliminary brick arrangement model according to the user requirements and hole size. The brick arrangement information includes the type of block, the number of blocks, the unit price of the block, and the number of customized blocks.

[0097] The second determining module 26 is used to determine the optimal brick arrangement model based on the brick arrangement information in order to obtain the optimal brick arrangement scheme.
