Description

Formwork construction system and formwork construction method

[0001] The present invention relates to formwork construction in frame construction, and more specifically, to a formwork construction system and a formwork construction method that performs pre-construction of formwork in a virtual three-dimensional environment by applying a three-dimensional model of the formwork device extracted based on design information of formwork members required to construct the frame to a three-dimensional model of the frame.

[0002] Most construction failures in conventional structural (reinforced concrete) work could be attributed to the technical limitations of construction BIM (Building Information Modeling) and the social environment of the structural work.

[0003] Simply applying BIM to reinforced concrete may not allow the contractor to directly manage design-related tasks, which could lead to incomplete communication or the establishment of countermeasures with the construction company, as well as insufficient design documents or material defects.

[0004] In particular, structural work tends to rely heavily on the experience of on-site contractors, which can lead to errors in the precise dimensions, materials, and installation methods of formwork devices required at the actual construction site. Consequently, this results in reduced material precision and accuracy, as well as unnecessary material waste. Furthermore, since this is the first time such construction is being performed on-site, installation and dismantling take a long time, and unexpected variables may arise, potentially prolonging the construction period and causing unforeseen safety incidents.

[0005] As an example of conventional formwork construction, the 'prefabricated formwork for column construction' of Korean Patent Registration No. 10-0662018 fails to resolve the problem that a relatively large amount of labor and time is required for the installation and removal of the formwork.

[0006] This invention is designed to solve these problems and aims to implement efficient structural construction that improves conventional construction methods through more precise and accurate formwork pre-construction, thereby providing reduced construction costs, shortened construction periods, enhanced safety, and an improved site environment.

[0007] Furthermore, for smart and efficient structural construction, it is crucial that the formwork used during the concrete pouring process be designed with precision and accuracy. This not only minimizes errors and discrepancies that may occur at the construction site but also enables precise construction based on accurate material calculations.

[0008] Furthermore, the purpose is to provide an improved formwork construction system and formwork construction method that can maximize construction efficiency, reduce construction errors, prevent material waste, and enhance the safety of on-site work.

[0009] In a formwork construction system related to a first embodiment of the present invention for achieving the above-mentioned objectives of the present invention, the system may include a 3D modeling module that models 2D drawing data of a frame into 3D using BIM (Building Information Modeling); a drawing error review module that reviews errors in the 3D model of the frame and the 2D drawing data; a process plan establishment module that establishes a process plan for each construction section of the frame based on the 3D model of the frame; a library module that stores 3D modeling information of formwork members required to construct the 3D model of the frame; and a formwork pre-construction module that extracts a 3D model of a formwork device required for formwork construction of the 3D model of the frame from the library module based on the 3D model of the frame and the 3D modeling information of the formwork members stored in the library module, and applies the extracted 3D model of the formwork device to the 3D model of the frame to perform formwork construction in a virtual 3D environment.

[0010] In addition, in the formwork construction system, dimensional information such as the length, width, and height of the formwork member can be stored in the library module.

[0011] In addition, in the above formwork construction system, material information regarding the material characteristics, material, strength, and durability of the formwork member can be stored in the library module.

[0012] In addition, in the formwork construction system, connection information regarding the assembly method, connection structure, and joining method of the formwork member may be stored in the library module.

[0013] In addition, if the formwork construction system does not have a 3D model of a formwork device required for the formwork construction of the 3D model of the frame in the library module, it can create a 3D model of a formwork device required for the formwork construction of the 3D model of the frame and store it in the library module to update the library module.

[0014] In addition, in the formwork construction system, the formwork pre-construction module may further include a construction plan calculation unit that calculates at least one of a two-dimensional drawing of the formwork, a required quantity, and a required material cost based on the three-dimensional model of the formwork, when the extracted three-dimensional model of the formwork is suitable for performing the formwork construction.

[0015] In addition, in the formwork construction system, the formwork pre-construction module may further include a feedback module that modifies the 3D modeling information of the formwork member stored in the library module when the extracted 3D model of the formwork device is not suitable for performing the formwork construction, and updates and stores the modified 3D modeling information of the formwork member in the library module.

[0016] A method for constructing formwork using a formwork construction system having a library module unit related to a second aspect of the present invention may include: a step of modeling two-dimensional drawing data of a frame into three dimensions using BIM (Building Information Modeling); a step of reviewing errors in the three-dimensional model of the frame and the two-dimensional drawing data; a step of establishing a construction plan for each construction section of the frame based on the three-dimensional model of the frame; a step of storing three-dimensional modeling information of formwork members required to construct the three-dimensional model of the frame in the library module unit; and a step of extracting a three-dimensional model of a formwork device required for the formwork construction of the three-dimensional model of the frame from the library module unit based on the three-dimensional model of the frame and the three-dimensional modeling information of the formwork members stored in the library module unit, and applying the extracted three-dimensional model of the formwork device to the three-dimensional model of the frame to perform formwork construction in a virtual three-dimensional environment.

[0017] In addition, the above formwork construction method may further include the step of, if there is no 3D model of a formwork device required for the formwork construction of the 3D model of the frame in the library module, generating a 3D model of a formwork device required for the formwork construction of the 3D model of the frame and storing it in the library module to update the library module.

[0018] In addition, the above formwork construction method may further include the step of calculating at least one of a two-dimensional drawing of the formwork, a required quantity, and a required material cost based on the three-dimensional model of the formwork, if the extracted three-dimensional model of the formwork is suitable for performing the formwork construction.

[0019] In addition, the above formwork construction method may further include the step of, if the extracted 3D model of the formwork device is not suitable for performing the formwork construction, modifying the 3D modeling information of the formwork member stored in the library module and updating and storing the modified 3D modeling information of the formwork member in the library module.

[0020] In addition, the above formwork construction method may further include the step of manufacturing a formwork device and a formwork member based on the three-dimensional model of the formwork device when the extracted three-dimensional model of the formwork device is suitable for performing the formwork construction.

[0021] According to each embodiment of the present invention, through more precise and accurate formwork pre-construction, conventional construction methods can be improved, thereby enabling efficient structural construction that provides reduced construction costs, shortened construction periods, enhanced safety, and an improved site environment.

[0030] Hereinafter, with reference to the attached drawings, a formwork construction system and a formwork construction method according to preferred embodiments of the present invention will be described in detail as follows.

[0031] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. Furthermore, these embodiments are provided to more fully explain the present invention to those skilled in the art. Accordingly, the shapes or positions of elements in the drawings may be exaggerated to emphasize clearer explanations. In the following description, specific descriptions of parts that can be easily implemented by a person skilled in the art may be omitted.

[0032] As used herein, the terms “part” or “module” refer to hardware components such as software, FPGAs, or ASICs, and the “part” or “module” performs certain roles. However, the meaning of “part” or “module” is not limited to software or hardware. The “part” or “module” may be configured to reside in an addressable storage medium or may be configured to operate one or more processors. Accordingly, the “part” or “module” may include components such as software components, object-oriented software components, class components, and task components, as well as processors, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The components and functions provided within the “part” or “module” may be combined into a smaller number of components and “parts” or “modules,” or further separated into additional components and “parts” or “modules.”

[0033] In addition, the role or function of each component of the formwork construction system of the present invention may be executed by, for example, one or more processors, or may be performed by an application including a computer program installed on a user terminal including a user's computer or smartphone, connected to a server via an online communication means including the Internet.

[0034] At this time, the program in which the function of each module is executed can be executed not only by architectural design-related programs such as Auto CAD, Revit, and SketchUP, but also by all general-purpose programs capable of 3D modeling such as Blender and SolidWorks, and can be executed through various programs without being limited to a specific program.

[0035] A formwork construction system (100) corresponding to the first embodiment of the present invention may include, as shown in FIG. 1, a three-dimensional modeling module (110), a drawing error review module (120), a process planning module (130), a library module (140), and a formwork pre-construction module (150). At this time, each module may be configured as an independent device or may be implemented as a software module included within a single device.

[0036] Specifically, the configuration and processing of each module of the formwork construction system (100) of the present disclosure may be freely combined and carried out by one or more devices, provided that no technical contradiction arises. For example, the configuration and processing of each module may be executed by one device, and the processing described as being performed by one device may be divided and carried out by multiple devices. Depending on the design method of the system, such processing methods may be freely combined and, if necessary, controlled by a central processor or distributed processing.

[0037] First, the 3D modeling module (110) can model the frame to be constructed in 3D using BIM (Building Information Modeling, hereinafter referred to as “BIM”) techniques based on 2D drawing data of the frame to be constructed, as shown in FIG. 3.

[0038] At this time, BIM (Building Information Modeling) technique can refer to a digital 3D model integrated management technology for the process of virtually modeling facilities in a multidimensional virtual space, including planning, design, engineering (structure, equipment, electrical, etc.), construction, and even maintenance and disposal.

[0039] By digitizing buildings through BIM to generate numerical data, a three-dimensional display effect can be achieved. Rather than simple line and surface operations, data regarding lengths connecting the start and end points of lines is generated, and surface areas are digitized based on closed planes. Furthermore, volume data can be obtained by combining length and area data. In this way, BIM represents the individual attributes of building objects such as walls, slabs, windows, doors, roofs, and stairs to recognize their interrelationships and immediately reflects changes to the building design. Regardless of whether the building being designed is standardized or irregular, BIM can be utilized to integrate and manage information across all stages of construction by ensuring compatibility and sharing of data generated by project and process.

[0040] Next, the drawing error review module (120) can review the error by comparing the 3D model of the frame modeled using BIM techniques with the 2D drawing data, as shown in FIGS. 4a to 4e.

[0041] The drawing error review module (120) can review structural errors in the frame, such as whether the stairwell walls of adjacent floors are spaced apart from each other and interference between structures has occurred, or whether there is interference between the underground foundation piles and ground anchors, as shown in FIGS. 4a and 4b, and display the results.

[0042] In addition, the drawing error review module (120) may review structural errors in the frame and display the results by anticipating the flow after actual construction, such as whether the foundation of the neighborhood living facility interfered with the interior of the underground parking lot, or whether the level of the outdoor sewage and drainage pipe is formed higher than the sewage and drainage pipe inside the underground parking lot, making it impossible to discharge sewage and drainage outdoors.

[0043] In addition, the drawing error review module (120), as shown in FIG. 4e, compares the 3D model of the frame with the 2D drawing data and distinguishes between a ‘structural interference LIST’ and a ‘representation difference LIST’ to indicate whether the drawing error is due to interference of the structure itself or simply due to a difference in representation.

[0044] Next, as illustrated in FIGS. 5a and 5b, the process planning module (130) can review and correct errors in the drawing based on the three-dimensional model of the frame and the results of the review by the drawing error review module (120), then establish a process plan and generate and display a chart.

[0045] In this way, as the process planning module (130) manages the construction process based on the construction BIM, it is possible to visualize the basic process plan to adjust the construction plan rationally, identify problems or establish countermeasures through the management of the actual process status, and finally manage the progress to ensure compliance with the construction period.

[0046] The library module (140) may store three-dimensional modeling information of various formwork members required to construct a three-dimensional model of the frame. This three-dimensional modeling information may include data that accurately represents the shape, location, and arrangement state of the formwork members, thereby allowing for a clearer understanding of the space each formwork member will occupy and the interrelationships between the members during the construction process.

[0047] For example, the library module (140) may store dimensional information such as the length, width, and height of the formwork members, and this may include values ​​pre-designed to match the shape of the frame. Through this dimensional information, each formwork member can be accurately joined and positioned to one another, thereby minimizing dimensional errors that may occur during construction.

[0048] In the library module (140), material information regarding the material properties, material type, strength, and durability of the formwork member may be stored. For example, whether materials such as steel, aluminum, and synthetic plastic are used may be stored, and physical properties such as the strength, durability, and elastic modulus of the material may also be included. This material information may be used to evaluate the resistance of the formwork member to loads and external environments during construction.

[0049] In the library module (140), connection information regarding the assembly method of the formwork member, the structure of the connection part, and the joining method may be stored. The joining method may include various methods such as bolt joining, clamp joining, or welding, and may also include information regarding the robustness of the connection part or the convenience during disassembly. This connection information can increase the efficiency of assembly and disassembly at the site, while simultaneously preventing joining errors in the connection part that may occur during construction.

[0050] The formwork pre-construction module (150) simulates formwork construction in advance based on a three-dimensional model of a frame and three-dimensional modeling information of formwork members stored in the library module (140), as illustrated in FIG. 6a and 6b. The formwork pre-construction module (150) extracts a three-dimensional model of a formwork device required for formwork construction from the library module (140), and through this, can precisely review the construction process by simulating it in a virtual environment before actual construction.

[0051] Specifically, the formwork pre-construction module (150) first automatically searches for and extracts a 3D model of each formwork device that matches the 3D model of the frame from the library module (140). In this process, formwork devices that match the frame are extracted by considering the size, shape, material, etc. of the formwork members. Subsequently, the 3D model of the extracted formwork device is applied to the 3D model of the frame, and it is possible to simulate how the formwork member is combined and installed with the frame in a virtual 3D environment. In the simulation process, it is possible to review in advance whether the formwork member or formwork device does not fit the frame or if interference occurs, and the design can be modified or supplemented based on the results of this review.

[0052] If the formwork construction system (100) does not have a 3D model of a formwork device required for the formwork construction of a 3D model of a frame in the library module (140), it may create a 3D model of a formwork device required for the formwork construction of a 3D model of a frame and store and update it in the library module (140).

[0053] Specifically, a 3D model of a suitable formwork device can be designed by considering the structural characteristics of the frame, the scope of construction, and material requirements. In this case, the entity creating the model is independent of whether it is a user (human) or an AI (Artificial Intelligence, hereinafter referred to as 'AI'), and is not restricted by the entity. For example, the AI ​​can design a 3D model of a suitable formwork device based on existing design data and through comparative analysis with previous construction cases, and the user can perform this to update the latest design information for formwork members and formwork devices.

[0054] The 3D model of the formwork device generated at this time is then automatically saved to the library module (140), thereby updating the existing database (DB). The updated 3D model of the formwork device can be reused for future construction of a frame structure of the same or similar structure, and can also be shared with other user terminals, thereby maximizing the usability of the data.

[0055] The formwork pre-construction module (150) may further include a construction plan calculation unit (151) and a feedback module (152), as shown in FIG. 2.

[0056] The construction plan calculation unit (151) can calculate a two-dimensional drawing of the formwork device based on the three-dimensional model of the formwork device when it is determined that the three-dimensional model of the formwork device is suitable for performing formwork construction, as shown in FIG. 7a.

[0057] Whether a 3D model of a formwork device is suitable for performing formwork construction can be determined manually by a human, or automatically by AI or a program. In this case, the determination criteria may include whether the load-bearing capacity and stability of the 3D model of the formwork device itself, the structural characteristics of the 3D frame, the construction scope, and material requirements satisfy established standards. Additionally, it may include whether the 3D model can provide sufficient load-bearing capacity and stability against the expected design load of the frame (i.e., loads and external forces expected during construction).

[0058] Furthermore, in determining whether the 3D model of the formwork device is suitable for performing formwork construction, it may be reviewed whether the 3D model of the formwork device was designed according to the designed dimensions, and whether the materials, dimensions, locations, and connection methods of all formwork members required for actual construction meet the design conditions. At this time, building regulations, seasonal weather conditions, or site conditions may be reflected in the design conditions.

[0059] When an AI or program performs such a judgment, it can determine suitability by comparing and analyzing past construction cases based on existing design data, and the determined result may be reviewed by a person or applied automatically. If, as a result of the judgment, the 3D model of the formwork device is determined to be suitable for formwork construction, the construction plan calculation unit (151) converts the 3D model of the formwork device into a 2D drawing and automatically generates a drawing that can be used at the actual construction site. The 2D drawing may include the location of each member, connection method, construction sequence and assembly method, and can be used as a construction guideline at the site.

[0060] In addition, the construction plan calculation unit (151) can calculate the quantity of formwork required for construction based on a three-dimensional model of the formwork device as illustrated in FIGS. 7b to 7c, and this may include a list of materials and quantities calculated based on the number, size, weight, etc. of each formwork member. Through this, efficient material management is possible and waste of unnecessary materials can be reduced.

[0061] Furthermore, the construction plan calculation unit (151) may calculate the necessary material costs based on the calculated quantity of formwork devices. When calculating the material costs, the material costs may be calculated based on the size, volume, weight, or unit price information of the material of the calculated formwork devices. In addition, the total cost including incidental costs required for transportation or installation of materials may be calculated along with the material costs. Through this, the construction company can proceed with budget planning and cost management more efficiently and minimize the gap between the expected cost and the actual cost.

[0062] The feedback module (152) can optimize the formwork design and construction process by providing feedback based on the case where the 3D model of the extracted formwork device is determined not to be suitable for performing formwork construction, that is, when it does not match the construction requirements or does not match the 3D frame modeling.

[0063] Specifically, the feedback module (152) can modify the 3D modeling information of the formwork member and formwork device by an automatic modification algorithm or by a user. This modification process is independent of whether the user (human) or AI is involved, and is not restricted to the subject. For example, the AI ​​may recommend a better option through comparative analysis with previous construction cases based on existing design data, or automatically readjust the dimensions of the 3D modeling information of the formwork member and formwork device according to design specifications, or the user may perform this to update the design information of the latest formwork member and formwork device.

[0064] Furthermore, the feedback module (152) may enable collaboration with other users when updating and storing 3D modeling information. Specifically, various authorized designers or contractors may share the components by sharing modeling information in real time from other users' terminals or by synchronizing updated data. For example, even if multiple construction teams are working in different regions, the design and construction of the formwork can be done through shared library data, thereby reducing construction discrepancies between sites and maintaining the efficiency and consistency of the formwork design.

[0065]

[0066] Referring to FIG. 8, a formwork construction method using a formwork construction system equipped with a library module corresponding to the second embodiment of the present invention will be described.

[0067] Each component and processing of a formwork construction system equipped with a library module may be carried out by freely combining one or more devices, provided that no technical contradictions arise. For example, the configuration and processing of each step may be executed by one device, and the processing described as being performed by one device may be distributed and executed by multiple devices. Depending on the design method of the system, such processing methods may be freely combined and, if necessary, controlled by a central processor or distributed processing.

[0068] First, when the formwork construction method according to the present embodiment begins (S200), the 2D drawing data of the frame is modeled in 3D using BIM (S210).

[0069] Next, the 3D model of the frame modeled using BIM techniques and the 2D drawing data are compared to review errors in the 3D model of the frame and the 2D drawing data (S220).

[0070] At this time, based on the 3D model of the frame and the results of the drawing error review, the errors in the drawing can be reviewed and corrected, a process plan can be established, and a chart can be generated and displayed (S230). In addition, 3D modeling information of formwork members required to construct the 3D model of the frame can be stored in the library module (S240).

[0071] Next, based on the 3D model of the frame and the 3D modeling information of the formwork members stored in the library module, the construction of the formwork can be simulated in advance in a virtual 3D environment (S250).

[0072] Specifically, if a 3D model of a formwork device required for the formwork construction of a 3D model of a frame does not exist in the library module, a 3D model of a formwork device required for the formwork construction of a 3D model of a frame can be created and stored and updated in the library module (S251). At this time, the newly created 3D model of the formwork device is stored and updated in the library module of the formwork member information storage step (S240), and the formwork pre-construction step (S250) can be repeated.

[0073] If the extracted 3D model of the formwork device is suitable for performing formwork construction, the method may further include the step of calculating at least one of the 2D drawing of the formwork device, the required quantity, and the required material cost based on the 3D model of the formwork device (S252).

[0074] At this time, whether the extracted 3D model of the formwork device is suitable for performing formwork construction can be determined based on whether the load-bearing capacity and stability of the 3D model of the formwork device itself, or the structural characteristics of the 3D frame, the construction scope, or material requirements satisfy established standards, and also based on whether the 3D model of the formwork device can provide sufficient load-bearing capacity and stability for the expected design load of the frame.

[0075] Furthermore, in determining whether the 3D model of the formwork device is suitable for performing formwork construction, the determination may be made based on whether the 3D model of the formwork device is designed according to the designed dimensions, and whether the materials, dimensions, locations, and connection methods of all formwork members required for actual construction match the design conditions. In this case, building regulations, seasonal weather conditions, or site conditions may be reflected and set as design conditions.

[0076] Meanwhile, if the 3D model of the extracted formwork device is not suitable for performing formwork construction, the 3D modeling information of the formwork member stored in the library module can be modified, and the modified 3D modeling information of the formwork member can be updated and stored in the library module (S253). At this time, the modified 3D modeling information of the formwork member is stored and updated in the library module of the formwork member information storage step (S240), and the formwork pre-construction step (S250) can be repeated.

[0077] After the formwork pre-construction stage (S250) and the construction plan calculation stage (252) have at least one of the two-dimensional drawing of the formwork device, the required quantity, and the required material cost, a step of manufacturing the actual formwork device and formwork member may be further included. Specifically, if the extracted three-dimensional model of the formwork device is suitable for performing the formwork construction, the formwork device and formwork member may be manufactured based on the three-dimensional model of the formwork device, and the scope of the present invention extends to the formwork device and formwork member formed through the above method.

[0078] The generated formwork device and formwork components may include an additional step of being transported to the site and installed by a table manufactured in the factory. Since the formwork has undergone a pre-construction stage (PRE-CON), it is simply necessary to assemble and install it at the site, thereby shortening the manufacturing and installation time and improving the speed of construction and work. Furthermore, through modularization of components, the labor fatigue of workers is reduced, and the amount of work at the site is fundamentally reduced.

[0079] Subsequently, concrete is poured based on the installed formwork, and once the concrete has sufficiently developed strength, the installed formwork components are safely demolded and removed. At this time, since formwork suitable for the frame is constructed, noise and dust associated with the fabrication and dismantling of the formwork are minimized, and the generation of work by-products and waste is reduced, thereby improving the site environment.

[0080] According to each embodiment of the present invention, through more precise and accurate formwork pre-construction, conventional construction methods can be improved, thereby enabling efficient structural construction that provides reduced construction costs, shortened construction periods, enhanced safety, and an improved site environment.

[0081] Although embodiments of the present invention have been illustrated above, each of the above embodiments is merely an example, and the present disclosure may be implemented by appropriately omitting, substituting, combining, or modifying within the scope of not departing from the gist thereof. Furthermore, the configurations and processes described in the present disclosure may be freely combined and implemented as long as no technical contradictions arise. Additionally, a process described as being performed by a single device may be divided and executed by a plurality of devices. Furthermore, a process described as being performed by different devices may be executed by a single device.
