The general status and problems of PC component production at this stage

 

As more and more companies begin to pay attention to the transformation of building industrialization, some PC component production and processing plants have also been established, but at this stage, all factories face the following problems:

Application case of BIM in prefabricated component factory_1

1. Uncertainty about product types leads to non-discipline of factory planning: For the selection and positioning of pre-fabricated products before establishment, it is necessary to have a clear understanding of market demand and to meet market demand. The last word is going down. The overall planning of the product's recent demand in the medium and long term needs to be mastered in order to ensure its economic and scientific.

 

2. Only factoryization is achieved, and mechanization is not realized: it is not difficult to achieve a factory-made manufacturing method. Simple can be understood as moving the work of the construction site to the factory floor, changing the work site and improving the working environment, but Without improving the production efficiency, it is still the work of the sea tactics, and the quality of the products cannot be well controlled.

 

3. Mechanization is only realized, and automation is not realized: after the mechanization method is introduced in the factory production of the prefabricated parts, the work efficiency is improved, and the frequency of occurrence of defective products is reduced. However, in the entire production process, it exists in the form of a work site, which causes a lot of inconvenience in management, and is also not conducive to the innovation of process technology.

 

4. Automatization only, modernization of group management information has not been realized: The assembly line of prefabricated parts automation has been gradually introduced and used by various pc factories, and it has shown that a relatively small footprint can achieve higher production capacity. The number of labor is also greatly reduced, and it has a good performance for quality control and safety management. However, when the group manages multiple pc factories across regions, many problems are also urgently needed to be solved by large group companies.

 

5, can effectively build embedded parts and facilities equipment library and design software seamlessly docked

Different embedded parts will be created and built up for the deepening of different projects, because each project has its own unique and special processing methods, so it is necessary to interface with the design software. Data lossless transmission and reading can ensure the subsequent work goes smoothly.


6. Make production orderly, although the shape of the produced components is different, but the efficiency is not low.

Since the production line of prefabricated parts uses an information control system, digital control methods are used from the source. Therefore, in the production, the mechanical device reads the data format file, and the degree of precision control can be within millimeters, and to some extent, the degree of free change of the production component can also be changed in millimeters.

It can be seen that the so-called "modular limitation" in the traditional sense does not exist here, breaking through the contradiction between individualized design and industrialized production, and finally achieving the difference in the shape of the components produced, but the efficiency is not low, let Production is equally orderly.


7. Scientific logistics management system and guarantee reliable logistics management

Deliver the correct quantity and type of prefabricated components or parts directly to the project site. To achieve this, information control systems need to be linked with ERP to achieve information sharing. ERP reflects the requirements of the prefabricated components to be installed at the project site to the information control system, so that the management personnel can prepare in time, understand their inventory capabilities, and reflect them in the system in real time, complete the stacking operations in advance, and then complete the work directly on time. Delivered to the task of the project site.


8, the connection between production management and ERP

Manage production orders, including maintaining production orders and displaying a list of orders. According to different orders, materials and workshops, the materials can be prepared for different materials, reflecting the guarantee of the existing stocks on the production orders, listing the missing materials, reminding the management personnel to track or collect the missing materials in time, and not to produce the production orders. However, it was impossible to produce due to lack of materials.

1. About the pre-production preparation stage

The use of information technology to generate accurate bills of materials, 3D drawings and other data can effectively help the prefabricated parts in the production of technical disclosure, material procurement preparation, production planning, stacking site management and finished product logistics planning. It solves and avoids the abnormal state that occurs in the whole process of production in advance, and embodies the application of planning, execution, inspection and rectification (PCDA) cycle management method in prefabrication management.

 

2, production and processing production map - machinery

The designer will deepen the drawings, forms, documents and other information after the completion of the split design and transmit it to the server in the form of data, and convert it into a format that the machine can recognize and enter the production stage. Automate through control programs to reduce the possibility of labor and errors.

 

3. Real-time monitoring of production through control system

The production of prefabricated parts is the main flow operation:

A series of abnormal conditions such as faults and delays generated in the above production process are effectively monitored by the control system, and are promptly reflected to the management personnel to make judgments to avoid problems caused by human causes.

 

4, automatically summarize the production efficiency and labor of various products, easy to manage

During the production process of the prefabricated parts, the control system records the information of each component, including the flow tempo, the size of the components, the reserved openings and the embedded parts, the number of working hours, etc., and records and records according to different items, different dates and different types of components. Statistics make it easy for managers to analyze and improve in the later stage.

 

5, can effectively build embedded parts and facilities equipment library and design software seamlessly docked

Different embedded parts will be created and built up for the deepening of different projects, because each project has its own unique and special processing methods, so it is necessary to interface with the design software. Data lossless transmission and reading can ensure the subsequent work goes smoothly.

1. Order to pre-preparation

First, after signing the project, sign the contract and arrange the order processing plan according to the capacity planning; then the design institute completes the traditional structural construction drawing design, deepens the design team to accept the complete set of drawings and related materials for the transformation and split design, and deepens the finished design drawings. The design institute is submitted for review as part of the construction drawing. After the approval of the plan, the traditional project process begins. At the same time, the prefabricated component factory begins the material procurement, production planning, and preparation of the finished product yard.

 

2, production planning, control to logistics

The designer will deepen the drawings, forms, documents and other information after the completion of the split design and transmit it to the server in the form of data. The project construction management personnel will arrange the construction and installation sequence according to the project layout plan, and submit it to the production management in the form of the task power of attorney. Personnel and determine production time.

The production management personnel complete the component stacking and scheduling design according to the deepened design data, and prepare various production data (such as labels, stacking tables, steel processing sheets, paper drawings, technical materials, etc.) and submit them to the workshop management personnel for preparation. produce. According to the production schedule, the work design is converted into a mechanically identifiable format and then entered the production stage. After the finished products are finished, they will be stacked in an orderly manner according to the plan of the stacking design to ensure smooth completion after installation to the site.

 

3, logistics to install to settlement

The project construction management personnel arranges the delivery time of the factory according to the overall progress requirements of the project and the on-site construction conditions, and the production management personnel start to deliver according to the installation and construction sequence of the layout drawing and the stacking design. Each prefabricated component has a unique tag code when the project is installed on site. The information control system records each prefab that is installed on site and provides information about the progress. The content can be visualized immediately in the form of a virtualized model or table. Even transportation and installation plans can be graphically run. After the project is installed, the information control system is linked with the ERP to realize financial sharing of information sharing.

 

4. The essence of designing from component drawings to production data is to anticipate difficulties in the implementation process.

This goal is in line with our philosophy of designing, evaluating, producing and processing views. Design not only means drawing, but also data. These data can be automatically analyzed and applied to production, logistics and settlement in a one-to-one mode. Design refers not only to paper-based files, but also to objects that we can view, which contain relevant data and view information.

In the whole process of the project, the production of architecture, structure, electromechanical and other professions can work on the same platform, and can simultaneously calculate information about quantity and cost. According to the stage or type of the project, there are features of 2D graphics and 3D modeling switching. Therefore, 2D and 3D can be selected according to the needs to select the most suitable expression.

Allplan (now renamed Planbar Precast) can transfer data without errors between other software, from design to factory and installation of uninterrupted data and drawings, complete molding and reinforcement drawings, production drawings, projects List and quantity calculations. Automatic transfer of data to the master control system, factory machines and corporate resource planning systems. Accurate features avoid multiple input and multiple data calculations.

 

5. Central control system for production

The central control system for production management information uses standard commercial Ethernet, and the network covers the production management departments of the factory. The system can monitor the equipment status and process parameters on the production line, and can display it on the screen in the form of a chart. The system department sorts the list by various ways according to the collected various production data. These data provide preservation, maintenance, query, statistics, and multivariate regression analysis. At the same time, the system can complete the statistics of the production report, the daily management of the material library.
