[0002] The advantage of prefabricated buildings is modular assembly, and all building materials can be prefabricated in advance to meet the requirements of fast assembly. However, the disadvantage of prefabricated buildings is that during the assembly process, there is no standardized constraint on the assembly process, resulting in the weak earthquake and typhoon resistance of the assembled buildings. Therefore, it is necessary to conduct deflection detection of the assembly process and the assembled buildings through modeling, so that the assembled buildings can meet the set earthquake and typhoon resistance requirements. Summary of the invention

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0006] Construct the assembly model in BIM based on the design drawings and design parameters of the assembly, and store the constructed assembly model in the set storage area;

[0007] According to the assembly process, the assembled building model is constructed with the assembly model as the main body, and during the construction process, the assembly path of each assembly model is tracked in turn through the set tracking module, and the assembly path is counted and recorded and stored in the tracking module;

[0008] Performing an assembly inspection on the constructed prefabricated building model according to the assembly path and assembly process to determine that there is no problem in assembling the prefabricated building model, and then configuring a set of positioning tags for each assembly model according to the assembly path, and the positioning tags are configured to record the swing displacement range of the assembly model when the assembly model is in the swing process;

[0009] Different deflection forces are set, and the set deflection forces are applied to the prefabricated building model in sequence to perform a deflection test. The deflection displacement range of the assembly model during each swing is recorded through positioning tags, and the effectiveness of the assembly process of the assembly model is evaluated through the deflection displacement range I, and the deflection amplitude range of the prefabricated building model is evaluated through the deflection displacement range II.

[0010] Furthermore, the method of sequentially tracking the assembly path of each assembly model by using the set tracking module includes:

[0011] When the assembled building model is constructed based on the assembly process with the assembly part model as the main body, the corresponding assembly part models are sequentially loaded from the storage area to the assembly positions specified by the assembly process through the loading module;

[0012] When the loading module loads the corresponding assembly model to the position specified by the assembly process, the tracking module and the loading module form data synchronization, and at the same time, the tracking module tracks and configures according to the clock mark based on the storage location information of the assembly model and the assembly position specified by the assembly process to form a tracking unit with clock marks, and tracks whether the assembly is completed based on the tracking unit, and when the tracked assembly is completed, the tracking unit forms an assembly path with the movement path of the assembly model, and records it accordingly in the recording unit set in the tracking module, and at the same time writes the storage location information of the assembly model and the assembly position specified by the assembly process under the assembly path.

[0013] Furthermore, the assembly process is provided with position data between assembly part models included in the assembled building model and assembly combination process during assembly; as well as quantity, specification information and corresponding material information of the assembly part models.

[0014] Furthermore, performing assembly inspection on the constructed prefabricated building model according to the assembly path and assembly process includes the following:

[0016] Recall several tracking units marked with clocks in the tracking module, and track the assembly paths under the units in sequence according to the sequence of time marks, and obtain the storage location information of the assembly model and the assembly position specified by the assembly process from the assembly path, compare the obtained storage location information of the assembly model with the loading directory of the loading module from the storage area, and compare whether the storage directory of the assembly model and the loading directory of the loading module from the storage area are consistent. If they are consistent, compare the position data between the assembly position specified by the assembly process and the assembly model included in the assembly process that constitutes the prefabricated building model to see whether the assembly position specified by the assembly process of the assembly model under the set storage directory is consistent with the position data of the assembly model included in the prefabricated building model. If they are consistent, perform the detection of the next assembly model until completion. If they are inconsistent, revise the assembly model according to the assembly combination process when assembling the assembly model, as well as the quantity, specification information and corresponding material information of the assembly model.

[0017] Furthermore, the tracking module and the loading module are respectively coupled with the clock module. After the tracking module and the loading module form data synchronization, the tracking module sends a clock mark request instruction to the clock module. After receiving the request instruction, the clock module sends a marking command to the coupled tracking module. The tracking module enables the marking unit set in the tracking module according to the marking command.

The real-time position data obtained by the dynamic positioning tags and the static positioning tags are transmitted to the processing module in real time according to the data transmission path. The processing module calculates the swing displacement range of the assembly model in each swing process according to the real-time position data obtained by the dynamic positioning tags and the static positioning tags.

[0024] The present invention pre-sets an assembly process according to artificial experience when designing an assembled building, then models the assembly parts and the assembled building through BIM technology, and performs different degrees of deflection detection on the assembled building model to determine whether the assembly process and the assembled assembled building model can meet the set requirements.

[0026] Figure 1 is a flow chart of the method of the present invention;

[0027] Figure 2 It is a schematic diagram of the system framework principle of the present invention. DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings.

[0029] Since prefabricated buildings have the characteristics of simple assembly process and modular assembly, the assembly process between different assembly parts can be set according to manual experience; therefore, when designing prefabricated building drawings, the assembly process between assembly parts can be set according to the assembly order between different assembly parts. The pre-set assembly process is not necessarily effective. Therefore, the present invention pre-sets an assembly process according to manual experience when designing prefabricated buildings, and then models the assembly parts and prefabricated buildings through BIM technology. The prefabricated building model obtained by the construction is tested for different degrees of deflection to obtain whether the assembly process and the assembled prefabricated building model can meet the set requirements. The present application can be used to simulate and verify the absorbed manual experience according to different building requirements, and optimize the assembly process.

[0030] Reference Figure 1 to Figure 2 The present invention provides a method for detecting the deflection of an assembled building based on BIM technology, comprising the following steps:

[0031] Construct the assembly model in BIM based on the design drawings and design parameters of the assembly, and store the constructed assembly model in the set storage area;

[0032] According to the assembly process, the assembled building model is constructed with the assembly model as the main body, and during the construction process, the assembly path of each assembly model is tracked in turn through the set tracking module, and the assembly path is counted and recorded and stored in the tracking module;

[0033] Performing an assembly inspection on the constructed prefabricated building model according to the assembly path and assembly process to determine that there is no problem in assembling the prefabricated building model, and then configuring a set of positioning tags for each assembly model according to the assembly path, and the positioning tags are configured to record the swing displacement range of the assembly model when the assembly model is in the swing process;

[0034] Different deflection forces are set, and the set deflection forces are applied to the prefabricated building model in sequence to perform a deflection test. The deflection displacement range of the assembly model during each swing is recorded through positioning tags, and the effectiveness of the assembly process of the assembly model is evaluated through the deflection displacement range I, and the deflection amplitude range of the prefabricated building model is evaluated through the deflection displacement range II.

[0035] It should be noted that in the design of prefabricated buildings, the parameter data of the assembly parts at different positions can be consistent or inconsistent, which is determined according to the design drawings of the prefabricated buildings. Therefore, in the process of building the assembly part model, the assembly part model can be set as a standard part model, and its design parameters can be modified according to specific requirements. Therefore, the design efficiency of the assembly part model can be improved. At the same time, the obtained standard part model can be stored in the BIM system to form a basic accessory model library.

[0036] It should be noted that the assembly process is provided with position data between assembly models included in the assembled building model and the assembly combination process during assembly; as well as the number, specification information and corresponding material information of the assembly models. Different assembly parts have many forms of installation methods in the actual assembly process, such as through concrete construction, and two assembly parts need to be overlapped and then bolted, etc. Therefore, the assembly process is not necessarily unique. The specific situation can be changed according to manual experience based on the actual assembly requirements. It should also be noted that when the same assembly parts are assembled in different positions, their corresponding design parameters and materials may be different. Therefore, the same shape does not mean that they are essentially the same. Therefore, it is necessary to record the specification information and corresponding material information of the assembly model in the assembly process.

[0037] In the above, the method of sequentially tracking the assembly path of each assembly model by setting the tracking module includes:

[0038] When the assembled building model is constructed based on the assembly process with the assembly part model as the main body, the corresponding assembly part models are sequentially loaded from the storage area to the assembly positions specified by the assembly process through the loading module;

[0039] When the loading module loads the corresponding assembly model to the position specified by the assembly process, the tracking module and the loading module form data synchronization, and at the same time, the tracking module tracks and configures according to the clock mark based on the storage location information of the assembly model and the assembly position specified by the assembly process to form a tracking unit with clock marks, and tracks whether the assembly is completed based on the tracking unit, and when the tracked assembly is completed, the tracking unit forms an assembly path with the movement path of the assembly model, and records it accordingly in the recording unit set in the tracking module, and at the same time writes the storage location information of the assembly model and the assembly position specified by the assembly process under the assembly path.

[0040] It should be noted that, according to the set assembly sequence, the loading module loads the corresponding assembly model from the storage area in sequence, and then changes the assembly model according to the specification information in the assembly process and the corresponding material information to form the assembly model required by the assembly process. When the loading module loads from the storage area, the storage directory of the corresponding assembly model is extracted. After the loading module loads the assembly model and assembles it, it moves it to the assembly position specified by the assembly according to the assembly process. Therefore, when assembling the prefabricated building model, it is necessary to record the storage location of the assembly model, the moving path during assembly, and the specific assembly position one by one. In this way, it is convenient to detect the assembly structure and assembly process of the prefabricated building model in the later stage.

[0041] In the above, the assembly inspection of the constructed prefabricated building model according to the assembly path and assembly process includes the following:

[0042] Obtaining the position data between the assembly models included in the assembled building model in the assembly process and the assembly combination process during assembly; as well as the quantity, specification information and corresponding material information of the assembly models;

[0043] Recall several tracking units marked with clocks in the tracking module, and track the assembly paths under the units in sequence according to the sequence of time marks, and obtain the storage location information of the assembly model and the assembly position specified by the assembly process from the assembly path, compare the obtained storage location information of the assembly model with the loading directory of the loading module from the storage area, and compare whether the storage directory of the assembly model and the loading directory of the loading module from the storage area are consistent. If they are consistent, compare the position data between the assembly position specified by the assembly process and the assembly model included in the assembly process that constitutes the prefabricated building model to see whether the assembly position specified by the assembly process of the assembly model under the set storage directory is consistent with the position data of the assembly model included in the prefabricated building model. If they are consistent, perform the detection of the next assembly model until completion. If they are inconsistent, revise the assembly model according to the assembly combination process when assembling the assembly model, as well as the quantity, specification information and corresponding material information of the assembly model.

[0044] In the above, the tracking module and the loading module are respectively coupled with the clock module. After the tracking module and the loading module form data synchronization, the tracking module sends a clock mark request instruction to the clock module. After receiving the request instruction, the clock module sends a mark command to the coupled tracking module. The tracking module enables the marking unit set in the tracking module according to the mark command. The marking unit configures the storage location information of the obtained assembly model and the assembly position specified by the assembly process to the tracking unit according to the clock mark to form a tracking unit marked with a clock.

[0045] In the above, configuring a set of positioning labels for each assembly model according to the assembly path includes:

[0047] At least one set of positioning tags is provided on each assembly model, and the at least one set of positioning tags includes: a dynamic positioning tag provided at least at the gravity center point of the assembly model, and a static positioning tag corresponding to the dynamic positioning tag;

[0048] The dynamic positioning tag is configured to: swing synchronously with the swing of the assembly model, and the swing distance is equal to that of the assembly model each time;

[0049] The static positioning tag is set to be equal to the initial setting position of the dynamic positioning tag, and is used to provide a reference for calculating the swing displacement of the dynamic positioning tag when the dynamic positioning tag swings synchronously with the swing of the assembly model.

[0050] In the above, the dynamic positioning tags and static positioning tags possessed by the same assembly model form label marks with the assembly path, and the data transmission paths of the dynamic positioning tags and the static positioning tags are set through the label marks. The real-time position data obtained by the dynamic positioning tags and the static positioning tags are transmitted to the processing module in real time according to the data transmission path. The processing module calculates the swing displacement range of the assembly model in each swing process according to the real-time position data obtained by the dynamic positioning tags and the static positioning tags.

[0064] The recording unit is connected to the tracking unit and is used to record the assembly path formed by the tracking unit and write the storage location information of the assembly model and the assembly position specified by the assembly process under the assembly path.

[0065] In the above, the configuration unit and the loading module are coupled to the clock module respectively. After the synchronization unit forms data synchronization with the loading module, it sends a clock mark request instruction to the clock module. After receiving the request instruction, the clock module sends a mark command to the configuration unit. The configuration unit enables the marking unit according to the mark command.
