Description

Technical Field

[0001] The invention relates to a five-degree evaluation method for precast beam production quality, belonging to a precast beam production quality evaluation technology in a smart beam yard. Background Art

[0002] The quality control of prefabricated parts refers to the strict supervision, inspection and control of the quality of prefabricated parts in each link of production, storage, transportation and installation to ensure that the components meet the design requirements and relevant standards, thereby ensuring the safety, reliability and durability of the entire building structure. However, the current prefabricated beam production quality management faces many challenges and shortcomings: 1. The rapid development of the industry has led to a shortage of professionals and industrial technical workers: The training of professional talents and industrial personnel cannot keep up with the rapid development of prefabricated concrete buildings. On-site operators can only perform on-site management based on the production manual, and it is difficult to predict the quality of prefabricated parts based on the actual production situation, resulting in common quality problems in the production process, affecting the appearance quality and safety of prefabricated components. This may reduce the stability and durability of the building, increase the cost of later maintenance, and may even cause safety accidents.

[0003] 2. Immature industrial support: Existing quality management methods often focus on certain specific links or indicators, and lack comprehensive consideration of the entire process of prefabricated beam production. For example, in the quality control of purchased parts, they may only focus on basic specifications and performance, while ignoring their synergistic relationship with the overall production quality.

[0004] 3. Lax implementation of quality control standards and specifications: During the on-site production process, many quality judgments are based on the subjective experience of on-site operators, lacking objective quantitative standards. If the quality control standards and specifications are not strictly implemented, defects in prefabricated parts may occur, such as substandard materials, design errors, and damage during transportation and installation. These problems may not only delay the progress of the project, but also increase repair costs. In some cases, they may also endanger the stability and durability of the building.

[0005] 4. Insufficient quality control during the production process: For key nodes in the production process, the monitoring and evaluation methods are not sophisticated and accurate enough, making it difficult to detect potential quality problems in advance. At the same time, the existing quality evaluation system has a lag in data collection and analysis, and cannot provide effective guidance for production adjustments in a timely manner.

[0006] 5. The quality traceability mechanism is not perfect: once a quality problem occurs, it is difficult to quickly and accurately locate the source of the problem and the scope of impact, which increases quality risks and costs. Moreover, there is a lack of effective integration and correlation between the various quality evaluation dimensions, making the evaluation results not comprehensive and systematic, and it is difficult to truly reflect the overall quality level of precast beams.

[0007] In the face of these shortcomings, an innovative and comprehensive five-degree evaluation method for precast beam production quality is urgently needed to improve the management level of precast beam production quality and ensure the high-quality delivery of precast beams. Summary of the invention

[0008] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a five-degree evaluation method for the production quality of precast beams, which comprehensively evaluates the production quality of precast parts from five aspects: component accuracy, thickness of steel bar protective layer, strength uniformity, permanent prestressing force, and appearance smoothness. The method aims to achieve a comprehensive, accurate and efficient evaluation of the production quality of precast beams through an innovative evaluation system and process, realize the refined management of key quality parameters of precast components, and improve the physical quality of components.

[0009] Technical solution: To achieve the above purpose, the technical solution adopted by the present invention is: A five-dimensional evaluation method for the production quality of precast beams is disclosed. The method comprises the following steps: splitting the precast beams into node products and purchased components at different levels according to the production process, establishing a one-way production sequence relationship between node products and purchased components at different levels, and forming a production plan with a tree diagram structure; designing quality requirements for purchased components, and conducting quality inspections on purchased components; designing production condition requirements and quality requirements for node products, and recording production conditions and conducting quality inspections on node products; firstly conducting single-dimensional component accuracy evaluation, steel bar protective layer thickness evaluation, strength uniformity evaluation, permanent prestressing force evaluation, and appearance smoothness evaluation on each purchased component and each node product, and then performing weighted summation of the five single evaluation results in combination with preset or set weights to obtain a five-dimensional quality evaluation result of each purchased component and each node product; and visually attaching the five-dimensional quality evaluation result of each purchased component and each node product to the production plan.

[0010] Specifically, the five-degree evaluation system for the production quality of precast beams is used to evaluate the quality of precast beams and their components; the five-degree evaluation system for the production quality of precast beams includes a purchased component model library, a node product model library, a component accuracy evaluation module, a steel bar protection layer thickness evaluation module, a strength uniformity evaluation module, a permanent prestressing evaluation module, an appearance finish evaluation module, a production planning module and a production quality traceability module; The purchased component model library is used to store each purchased component model, and the purchased component model includes a purchased component quality requirement unit, a purchased component quality detection unit, and a purchased component quality evaluation unit; the purchased component quality evaluation unit first performs a single-dimensional quality evaluation on the purchased components from five dimensions by calling a component accuracy evaluation module, a steel bar protective layer thickness evaluation module, a strength uniformity evaluation module, a permanent prestressing evaluation module, and an appearance smoothness evaluation module, and then performs a five-dimensional quality evaluation on the purchased components in combination with preset or set weights; The node product model library is used to store each node product model, and the node product model includes a parts list, a node product production condition requirement unit, a node product production condition recording unit, a node product production condition evaluation unit, a node product quality requirement unit, a node product quality detection unit and a node product quality evaluation unit; the parts in the parts list include the previous level node products or purchased parts required for the production of node products, and the connection between the node products of this level and the previous level node products or purchased parts is established by referencing the previous level node products or purchased parts in the parts list; the node product production condition evaluation unit evaluates the node product production conditions according to the node product production condition requirements; the node product quality evaluation unit first performs single-dimensional quality evaluation on the node products from five dimensions by calling the component accuracy evaluation module, the steel bar protection layer thickness evaluation module, the strength uniformity evaluation module, the permanent prestressing evaluation module and the appearance smoothness evaluation module, and then performs five-dimensional quality evaluation on the node products in combination with the preset or set weights; The production planning module, according to the production process of the precast beam, takes the precast beam as the last-level node product, and takes the node product in which all the components in the parts list are purchased components as the first-level node product; first downloads the last-level node product model from the node product model library, adds the previous-level node product and / or purchased components to the parts list, and then downloads the node product model and / or purchased component model level by level according to the parts list, sets the purchased product quality requirements for each purchased component model, sets the node product production condition requirements and node product quality requirements for each node product model, and forms a production plan; The production quality traceability module synchronizes the production plan, collects the quality inspection results of purchased parts, records the production conditions of node products, collects the quality inspection results of node products, conducts quality evaluation of purchased parts, evaluation of production conditions of node products and quality evaluation of node products; traces the previous level node product or purchased parts according to the parts list of the selected node product, or tracks the next level node product according to the reference status of the selected node product.

[0011] In this case, according to the needs of product quality inspection, the production process of prefabricated beams was split according to components, forming a production plan with a tree diagram structure, which can ensure that the production sequence and relationship of each part are clear and unambiguous, and provide a premise for traceability when product quality problems occur; at the same time, considering that prefabricated parts are essentially final products processed by components step by step, although the structure and quality evaluation standards of each level of products are different, the quality evaluation methods can be attributed to one or more of the following: component accuracy, steel bar protective layer thickness, strength uniformity, permanent prestressing force, and appearance smoothness. Therefore, from the perspective of quality evaluation, it is very feasible to simplify the components at each level into models with similar structures. As for whether all five dimensions need to be considered, they can be set in the parameterization stage of the model, such as setting the evaluation weight of dimensions that do not need to be considered to 0, etc.; building a production plan by calling the model also greatly reduces the design difficulty, and attaching the five-dimensional evaluation results to the production plan in a visual manner is also convenient for intuitive monitoring and adjustment of the quality status of the entire production.

[0012] The modular design of this case can also expand the prefabricated beams in upper and lower dimensions, expanding the scope of quality traceability; at the same time, production plans can be designed for each prefabricated beam separately, and personalized design and quality traceability can be carried out.

[0013] This case covers the key quality dimensions of precast beam production and ensures the comprehensiveness of quality control. It systematically manages the entire production process through a tree-like production plan. It improves the traceability of the production process through detailed quality inspection and evaluation records. It improves production efficiency through automated and systematic quality evaluation. It improves the quality and efficiency of precast beam production through a structured and visual approach. This is an advanced practice of quality control in the modern construction industry.

[0014] Specifically, the production quality traceability module uses a partitioned manner to display the results of tracing or tracking, including a tree diagram partition for tracing forward or backward from a selected node product, a production condition partition for a selected node product, and a production quality partition for a selected node product; in the tree diagram partition, the nodes in the tree diagram represent node products or purchased components, and the nodes simultaneously represent the node name, the production condition evaluation results, and the production quality evaluation results; in the production condition partition, the node product production condition requirements, the node product production condition records, and the node product production condition evaluation results are displayed simultaneously, usually in a tabular form; in the production quality partition, the node product quality requirements, the node product quality inspection results, and the node product quality evaluation results are displayed simultaneously, or the purchased component quality requirements, the purchased component quality inspection results, and the purchased component quality evaluation results are displayed simultaneously, usually in a tabular form.

[0015] Specifically, in the tree diagram partition of the production quality traceability module, the nodes are displayed in a manner of combined color blocks superimposed with text, wherein the text is used to represent the node name, and the combined color blocks are divided into at least two areas, one area represents the production condition evaluation results by different colors, and the other area represents the production quality evaluation results by different colors.

[0016] Specifically, in the tree diagram partition of the production quality traceability module, the nodes are displayed in the form of a circle superimposed with text, where the text is used to represent the node name and is displayed in the inner area of ​​the circle. The circle area and the inner area of ​​the circle represent the production conditions and production quality respectively. The circle area and the inner area of ​​the circle are filled with different colors to represent the production condition evaluation results and the production quality evaluation results. This design is considered to have the best visual effect during the actual measurement process. The quality evaluation adopts the results of the five-degree comprehensive evaluation, and does not adopt the method of displaying all the five-degree evaluation results. The comprehensive evaluation results are generally divided into three types, namely good, qualified and unqualified, and are represented by different colors.

[0017] Specifically, in the tree diagram partition of the production quality traceability module, left-click the selected node to update the information in the production condition partition and the production quality partition to the selected node; right-click the selected node to form an action instruction drop-down menu for the selected node, and the action instruction drop-down menu includes tracing back the node forward, tracing back the node backward, and adjusting the quality evaluation weight of the node; tracing back the node forward means tracing back the previous node product or purchased component according to the parts list of the node, and displaying the corresponding node in the tree diagram; if the corresponding node has been displayed in the tree diagram, selecting the action instruction will cancel the display of all forward tracing nodes of the node; tracing back the node means tracing the next node product according to the reference of the node, and displaying the corresponding node in the tree diagram; if the corresponding node has been displayed in the tree diagram, selecting the action instruction will cancel the display of all backward tracing nodes of the node; adjusting the quality evaluation weight of the node means adjusting the influencing factors of the component accuracy, steel bar protective layer thickness, strength uniformity, permanent prestress and appearance finish of the node on the quality of the node product, and performing weighted summation of the five-dimensional quality evaluation to calculate the comprehensive quality of the node.

[0018] Specifically, when using the production plan module to design a production plan, the purchased component model library, the node product model library, the production plan layout area, the parts list area and the parameter setting area are displayed in partitions; the purchased component model and the node product model are displayed in a graphical manner, and the model is added to the production plan by selecting the model and dragging it to the production plan layout area. Each model includes a forward connection point and a backward connection point; using a line to connect the backward connection point of the previous level model and the forward connection point of the next level model, the next level model is automatically added to the parts list of the previous level model; canceling the connection between the backward connection point of the previous level model and the forward connection point of the next level model, the next level model is automatically deleted from the parts list of the previous level model; for the selected model, the parts list of the model is displayed in the parts list area, and the purchased product quality requirements are set in the parameter setting area, or the node product production condition requirements and node product quality requirements are set. In this solution, forward connection points and backward connection points are designed for the model to ensure the order of connection. A simpler implementation solution is to design the model so that it can be moved or scaled within the production plan layout area, but not rotated. The connection points above the model are designed as backward connection points, and the connection points below the model are designed as forward connection points.

[0019] Beneficial effects: The five-degree evaluation method for the production quality of precast beams provided by the present invention can significantly improve the modernization level of precast beam production and achieve the construction goals of high efficiency, safety and environmental protection, which is specifically reflected in the following aspects: 1.

[0022] like Figure 1 The figure shows a five-dimensional evaluation method for the production quality of precast beams. First, the precast beams are split into node products and purchased components at each level according to the production process, and a one-way production sequence relationship is established between node products and purchased components at each level to form a production plan with a tree diagram structure; quality requirements for purchased components are designed, and quality inspection of purchased components is carried out; production condition requirements and quality requirements for node products are designed, and production condition records and quality inspection of node products are carried out; first, single-dimensional component accuracy evaluation, steel bar protective layer thickness evaluation, strength uniformity evaluation, permanent prestressing force evaluation and appearance smoothness evaluation are carried out on each purchased component and each node product, and then the five-dimensional quality evaluation results of each purchased component and each node product are obtained by weighted summing the five single evaluation results in combination with the preset or set comprehensive quality evaluation weights; the five-dimensional quality evaluation results of each purchased component and each node product are attached to the production plan in a visual manner.

[0023] The method of the present invention adopts the five-degree evaluation system of prefabricated beam production quality to evaluate the quality of prefabricated beams and their components; Figure 2 As shown, the five-degree evaluation system for prefabricated beam production quality includes a purchased component model library, a node product model library, a component accuracy evaluation module, a steel bar protection layer thickness evaluation module, a strength uniformity evaluation module, a permanent prestressing evaluation module, an appearance finish evaluation module, a production planning module and a production quality traceability module. The present invention is further described below in conjunction with each specific module.

[0024] 1. Procurement Parts Model Library The purchased component model library is used to store each purchased component model, and the purchased component model includes a purchased component quality requirement unit, a purchased component quality inspection unit and a purchased component quality evaluation unit; the purchased component quality evaluation unit first performs single-dimensional quality evaluation on the purchased components from five dimensions by calling a component accuracy evaluation module, a steel bar protective layer thickness evaluation module, a strength uniformity evaluation module, a permanent prestressing force evaluation module and an appearance smoothness evaluation module, and then performs a five-dimensional quality evaluation on the purchased components in combination with the preset or set comprehensive quality evaluation weights.

[0025] The purchased component model library can be increased or decreased as needed, including concrete, steel bars, basic prefabricated parts purchased from other manufacturers, etc. When a new purchased component is needed, the corresponding purchased component model must be designed in the purchased model library first; generally speaking, a graphical method is used to represent the purchased components, supplemented by attribute parameters. For example, a three-dimensional modeling method is used to construct a model of steel bars, and the attribute parameters include structural dimensions, material properties, etc.; it should be pointed out that in addition to the evaluation module involved in this case, special evaluation modules can also be used for specific purchased components.

[0026] 2. Node Product Model Library The node product model library is used to store each node product model. The node product model includes a parts list, a node product production condition requirement unit, a node product production condition recording unit, a node product production condition evaluation unit, a node product quality requirement unit, a node product quality detection unit and a node product quality evaluation unit; the parts in the parts list include the previous level node products or purchased parts required for the production of node products, and the connection between the node products of this level and the previous level node products or purchased parts is established by referencing the previous level node products or purchased parts in the parts list; the node product production condition evaluation unit evaluates the node product production conditions according to the node product production condition requirements; the node product quality evaluation unit first performs single-dimensional quality evaluation on the node products from five dimensions by calling the component accuracy evaluation module, the steel bar protection layer thickness evaluation module, the strength uniformity evaluation module, the permanent prestressing evaluation module and the appearance smoothness evaluation module, and then performs five-dimensional quality evaluation on the node products in combination with the preset or set comprehensive quality evaluation weights.

[0027] The node product model library can be increased or decreased as needed, including primary prefabricated parts, concrete mixtures, steel bar binding structures, etc. When a new node product is designed, it is necessary to first design the corresponding node product model in the node product model library; generally speaking, a graphical method is used to represent node products, supplemented by attribute parameters. For example, a prefabricated beam is modeled using a three-dimensional modeling method, and the attribute parameters include structural dimensions, material properties, etc.; it should be pointed out that in addition to the evaluation modules involved in this case, special evaluation modules can also be used for specific node products.

[0028] 3. Quality Evaluation Module The quality evaluation module includes the component accuracy evaluation module, the steel bar protection layer thickness evaluation module, the strength uniformity evaluation module, the permanent prestressing force evaluation module and the appearance smoothness evaluation module, as well as the five-dimensional comprehensive evaluation and production condition evaluation modules; the five-dimensional comprehensive evaluation can be designed as a separate module, or it can be directly designed in the component model (purchased component model and node product model), and it can be selected according to needs. The method adopted in this case is to design it directly in the component model. Component accuracy evaluation, steel bar protection layer thickness evaluation, strength uniformity evaluation, permanent prestressing force evaluation and appearance smoothness evaluation are all commonly used evaluation methods in the industry, but the quality evaluation parameters vary depending on the component; when designing this case, the quality evaluation parameters of each component are set in the component model. When participating in the evaluation, the corresponding evaluation module is called to use the set quality evaluation parameters for evaluation. When conducting a five-dimensional comprehensive evaluation, the comprehensive quality evaluation weight value of the five dimensions is also set in the component model.

[0029] The component accuracy evaluation module evaluates the dimensional accuracy and shape accuracy of the node products based on the node product quality inspection results and the node product quality requirements, and evaluates the dimensional accuracy and shape accuracy of the purchased parts based on the purchased parts quality inspection results and the purchased parts quality requirements.

[0030] The steel bar protection layer thickness evaluation module evaluates the steel bar protection layer thickness of the node product in combination with the node product quality inspection results and the node product quality requirements, and evaluates the steel bar protection layer thickness of the purchased parts in combination with the purchased parts quality inspection results and the purchased parts quality requirements.

[0031] The strength uniformity evaluation module evaluates the strength uniformity of node products based on the node product quality inspection results and node product quality requirements, and evaluates the strength uniformity of purchased components based on the purchased component quality inspection results and purchased component quality requirements.

[0032] The permanent prestressing strength evaluation module evaluates the permanent prestressing strength of node products based on the node product quality inspection results and node product quality requirements, and evaluates the permanent prestressing strength of purchased components based on the purchased component quality inspection results and purchased component quality requirements.

[0033] The appearance smoothness evaluation module evaluates the appearance smoothness of the node product in combination with the node product quality inspection results and the node product quality requirements, and evaluates the appearance smoothness of the purchased parts in combination with the purchased parts quality inspection results and the purchased parts quality requirements.

[0034] The production condition evaluation module evaluates the production conditions of the node product in combination with the node product production condition records and the node product production condition requirements.

[0035] Taking production conditions as an important part of quality evaluation is to facilitate the tracing of product quality problems. Therefore, product quality problems mainly come from two parts: one is component problems, and the other is production conditions problems.

[0036] 4. Production Planning Module 4.1 Basic framework of production planning module The production planning module, according to the production process of precast beams, takes the precast beams as the last node product, and takes the node product in which all the parts in the parts list are purchased parts as the first node product; first download the last node product model from the node product model library, add the previous node product and / or purchased parts in the parts list, and then download the node product model and / or purchased component model step by step according to the parts list, set the purchased product quality requirements for each purchased component model, set the node product production condition requirements and node product quality requirements for each node product model, and form a production plan. In theory, the precast beam can also be expanded, for example, the entire bridge can be used as the final node product. The difference lies in the way of using the five-degree evaluation system for precast beam production quality.

[0037] 4.2 Design of production planning module When using the production plan module to design a production plan, the purchased component model library, node product model library, production plan layout area, component list area and parameter setting area are displayed in partitions; the purchased component model and the node product model are displayed graphically, and the model is added to the production plan by selecting the model and dragging it to the production plan layout area. Each model includes a forward connection point and a backward connection point; using a line to connect the backward connection point of the previous level model and the forward connection point of the next level model, the next level model is automatically added to the component list of the previous level model; canceling the connection between the backward connection point of the previous level model and the forward connection point of the next level model, the next level model is automatically deleted from the component list of the previous level model; for the selected model, the component list of the model is displayed in the component list area, and the purchased product quality requirements and quality evaluation parameters are set in the parameter setting area, or the node product production condition requirements, node product quality requirements and quality evaluation parameters are set.

[0038] 5. Production quality traceability module 5.1 Basic framework of production quality traceability module The production quality traceability module synchronizes the production plan, collects the quality inspection results of purchased parts, records the production conditions of node products, collects the quality inspection results of node products, conducts quality evaluation of purchased parts, evaluation of node product production conditions and evaluation of node product quality; traces the previous level node product or purchased parts according to the parts list of the selected node product, or tracks the next level node product according to the reference status of the selected node product.

[0039] 5.2 Design of production quality traceability module The production quality traceability module uses a partitioned manner to display the results of tracing or tracking, including a tree diagram partition for tracing forward or backward from the selected node product, a production condition partition for the selected node product, and a production quality partition for the selected node product; in the tree diagram partition, the nodes in the tree diagram represent node products or purchased parts, and the nodes simultaneously represent the node name, production condition evaluation results, and production quality evaluation results; in the production condition partition, the node product production condition requirements, node product production condition records, and node product production condition evaluation results are displayed simultaneously; in the production quality partition, the node product quality requirements, node product quality inspection results, and node product quality evaluation results are displayed simultaneously, or the purchased part quality requirements, purchased part quality inspection results, and purchased part quality evaluation results are displayed simultaneously.

A specific design scheme adopted in this case is that in the tree diagram partition of the production quality traceability module, the nodes are displayed in the form of a ring superimposed with text, where the text is used to represent the node name and is displayed in the inner area of ​​the ring, the ring area and the inner area of ​​the ring represent the production conditions and production quality respectively, and the ring area and the inner area of ​​the ring are filled with different colors to represent the production condition evaluation results and the production quality evaluation results.

[0041] 5.4 Design of tree nodes in production quality traceability module In the tree partition of the production quality traceability module, left-click the selected node to update the information in the production condition partition and the production quality partition to the selected node; right-click the selected node to form an action instruction drop-down menu for the selected node. The action instruction drop-down menu includes forward tracing of this node, backward tracking of this node, adjustment of quality evaluation parameters of this node, and adjustment of comprehensive quality evaluation weight of this node; The forward tracing of this node refers to tracing back the previous node product or purchased parts according to the parts list of this node, and displaying the corresponding node in the tree diagram; if the corresponding node is already displayed in the tree diagram, selecting this action instruction will cancel the display of all forward tracing nodes of this node.

[0042] The backward tracking of this node refers to tracking the next-level node product according to the reference situation of this node, and displaying the corresponding node in the tree diagram; if the corresponding node is already displayed in the tree diagram, selecting this action instruction will cancel the display of all backward tracking nodes of this node.

[0043] The adjustment of the quality evaluation parameters of this node shown refers to adjusting the quality evaluation parameters of the component accuracy evaluation, steel bar protection layer thickness evaluation, strength uniformity evaluation, permanent prestressing force evaluation and appearance smoothness evaluation of this node, that is, the parameters set when this node calls the component accuracy evaluation module, steel bar protection layer thickness evaluation module, strength uniformity evaluation module, permanent prestressing force evaluation module and appearance smoothness evaluation module.

[0044] Adjusting the comprehensive quality evaluation weight of this node refers to adjusting the influencing factors of the component accuracy, steel bar protective layer thickness, strength uniformity, permanent prestress and appearance smoothness of this node on the node product quality, and calculating the comprehensive quality of this node by weighted summation of the five-dimensional quality evaluation.
