Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically to a digital matching method for space frame ball joints. Background Technology

[0002] During the project implementation phase, it is often desirable for the processing and transportation of components to meet on-site installation needs, ensuring that on-site installation proceeds according to the construction organization plan and avoiding work stoppages that could impact subsequent project schedules. However, in practice, situations frequently arise where components awaiting installation have not yet been shipped, while subsequent installation components have already been transported to the site. Insufficient component delivery to meet on-site installation requirements severely impacts project progress and schedule.

[0003] Space frame structures are a commonly used type of spatial truss structure, offering superior economic performance and standardized fabrication and installation. They are widely used in large-span buildings such as coal sheds, stadiums, airports, and astronomical facilities. Because their components are relatively standardized, situations where the delivery of certain components cannot meet on-site installation requirements can be addressed by replacing components that arrive in advance. This allows for the effective utilization of pre-arrived components, ensuring on-site installation progress and guaranteeing on-time project completion.

[0004] This application is made in this regard. Summary of the Invention

[0005] To address the technical problems existing in the prior art, this invention provides a digital matching method for net frame cues, which enables convenient selection and replacement of cues, ensuring the orderly progress of the entire construction process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a digital matching method for netball cues, comprising the following steps: Step 1: Create a BIM model containing basic information about the members and upload it to the data processor to generate QR code information for the members; Step 2: Personnel at each stage of processing and construction scan the QR code on the component and upload the current status information of the component to the central processing unit; Step 3: Intelligently update the status of the poles and display it on the terminal; Step 4: Select the poles to be installed but not yet present, and send the feedback to the central processing unit; Step 5: Establish evaluation criteria for compatible poles; Step Six: The central processing unit filters out a list of replaceable rods that are currently stacked on-site and meet the supporting standards; Step 7: Identify the replacement members and update the member status; Step 8: Issue a warning for re-cutting replacement components; Step 9: Locate and install replacement rods; Furthermore, the established BIM model of the space frame structure includes basic information such as the unique number of the members, length, cross-sectional dimensions, steel grade, spatial location, and construction schedule.

[0007] Furthermore, the BIM model data and component attributes are integrated into a data flow using a data processor, and each component is assigned a unique QR code. Factory technicians then use a QR code printer to print and affix the codes to the structural members.

[0008] Furthermore, at each specific stage of the server components (component cutting, finished product delivery, site acceptance, installation completion), authorized personnel at the corresponding stage use a PDA / mobile phone to scan the component's QR code, transmitting the component's status to the central processor. The central processor then reflects the component's status in real time to the BIM model, displaying the actual project progress status in the BIM model using different colors (component cutting: green, finished product delivery: purple, site acceptance: yellow, installation completion: red), ensuring that relevant parties can monitor the project progress in real time.

[0009] Furthermore, the welded spherical grid structure can be equipped with evaluation standards, with the cross-sectional dimensions of the members and the steel grade as mandatory conditions that must be met; the length of the members (or members + sleeves) as a set condition that must be within its tolerance control range; and the planned distance of the members as a preferred option, with those having a longer planned distance being preferred.

[0010] Furthermore, the bolted ball space frame can be equipped with evaluation standards, with the cross-sectional dimensions, length, and steel grade of the members as mandatory conditions that must be met; the planned distance of the members' construction period is a preferred option, with those having a longer planned distance being preferred.

[0011] Furthermore, this supporting method can also be used for ordinary steel beam members, especially for the replacement of secondary beams. The corresponding supporting evaluation standards are set with the cross-sectional height of the steel beam, the steel grade, and the member length as mandatory conditions that must be met; the cross-sectional width and thickness of the steel beam are set conditions that need to be within their tolerance control range; and the planned construction distance of the member is a preferred option, with those having a longer planned construction distance being preferred.

[0012] Furthermore, the central processing unit (CPU) filters replaceable members in the following order: First, it reads information such as the cross-sectional dimensions, grade, length, and schedule of members that are to be installed but not yet shipped. Then, it uses a multi-condition data filtering method to search within the member library in the status of arriving on site. Based on the cross-sectional dimensions, grade, length, and other information of the members, it filters out replacement members that meet the matching standards and then sorts them according to the distance of the schedule.

[0013] Furthermore, when updating the status of a member, if the member to be replaced is in an uncut state, the central processing unit will update the member to be replaced in the BIM model from an uncut state (blue) to an arrival state (yellow), while the member to be replaced will be updated from an arrival state (yellow) to an uncut state (blue). At the same time, the component number will be modified by adding one letter B to the original number to distinguish it, and a warning will be issued to the factory for reprocessing.

[0014] This invention allows for convenient selection of replacement members, reducing the impact of delayed delivery on on-site construction plans. It also enables flexible use of members that arrive early, reducing material accumulation on-site and preventing the impact of member replacement on delivered components, thus ensuring the orderly progress of the entire construction process. Attached Figure Description

[0015] Figure 1 This is a flowchart illustrating the workflow of the digital support method for netball cues according to an embodiment of the present invention. Detailed Implementation

[0016] Reference Figure 1 The specific implementation method of the present invention for digital matching of net frame cues will be further described.

[0017] This embodiment of a method for digitally matching netball cues includes the following steps: 1. Establish BIM models of the space frame structure and construction site and upload them to the data processor. The BIM model of the space frame structure includes basic information such as the unique number of the members, length, cross-sectional dimensions, steel grade, spatial location, and construction schedule. The initial color of the members is defined as blue.

[0018] 2. The BIM model data and component attributes are integrated into a data flow through a data processor, and a unique QR code is assigned. Factory technicians use a QR code printer to print and affix the code to the member.

[0019] 3. At each stage of finished component cutting, finished product leaving the factory, arriving at the site, and installation completion, the authorized personnel of the corresponding link use PDA / mobile phone to scan the component QR code, enter the relevant component and yard information, and transmit it to the central processor. The corresponding steel component BIM model is displayed with different colors: component cutting (green), finished product leaving the factory (purple), arriving at the site (yellow), and installation completion (red).

[0020] 4. When it is found during construction that the pole at location 1 needs to be installed on site first, but the display terminal query shows that the pole has not reached the acceptance status, select the pole at location 1 in the BIM model, feed back to the central processor, and establish an automatic pole search and replacement task plan.

[0021] 5. Set corresponding matching evaluation standards according to the type of members. For welded ball grid structures, the cross-sectional dimensions and steel grade of the members are mandatory conditions that must be met. The length of the members (or members + sleeves) is a set condition that must be within its tolerance control range. For bolted ball grid structures, the cross-sectional dimensions, length, and steel grade of the members are all mandatory conditions that must be met. For steel beams, the cross-sectional height, steel grade, and member length are mandatory conditions that must be met. The cross-sectional width and thickness are set conditions that must be within its tolerance control range. The planned construction period distance for each type of member is a preferred option, with those having a longer planned construction period distance being preferred.

[0022] 6. The method for the central processing unit to select replaceable members is as follows: The user right-clicks on the member to be replaced in the BIM model and clicks "Replace". After that, the central processing unit automatically reads the member's length, cross-sectional dimensions, and steel grade, and then performs multi-condition filtering within the member library under the acceptance status, based on the matching evaluation criteria, to find the replacement members that meet the standard requirements. The replacement members are then sorted according to the planned distance of the construction period to generate a list of replaceable members.

[0023] 7. After comprehensive evaluation by on-site technicians, the selected replacement rod is confirmed in the list, and the central processing unit updates the status of the replacement rod and the replaced rod.

[0024] The update method is as follows: Assuming the replacement member is located at position 2, after clicking "Replace," the processor changes the status of the member at position 1 to the color of the incoming inspection status of the member at position 2, and simultaneously changes the member number to the member number of position 2. Based on the principle of prioritizing economy, the status of the member at position 2 is updated according to the original status color of the member at position 1: when the original status of the member at position 1 was "cut," the member number of position 2 is directly changed to the member number of position 1; when the original status of the member at position 1 was "not cut," the member number of position 2 is modified by adding the letter "B" to the original number for distinction. Simultaneously, the BIM management platform automatically issues a re-cutting warning, indicating to the factory to re-cut and process the member.

[0025] 8. Locate the pole with number 2 at location and install it on site to meet the project schedule requirements.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
