As the important feature of prefabricated building components is standardized production, the BIM Technology can be used for standardized design in the design to fully present the information of components, and the information data can be directly connected with the component manufacturers to improve the efficiency of design and component production.
The reason for BIM Technology to achieve rapid and accurate design is that it has a relatively complete family library.
At the same time, it shall be noted that for special components such as complex structure and large volume, it shall also be considered that they will not be damaged by the construction during the storage process, and the site shall be reinforced for the components that are too heavy and too large, In addition, the space for component turnover shall be reserved for the later hoisting machinery.
Lifting points shall be carried out according to relevant safety operation specifications to ensure the safety of lifting construction..
At the same time, in this stage, the lifting points shall be reasonably set in the prefabricated components according to the requirements of relevant specifications and standards to facilitate the on-site lifting construction of later components.
Therefore, compared with the traditional construction and production mode, the primary production link of prefabricated buildings is carried out in the factory.
Designers can carry out secondary development on the basis of the software family library, constantly improve the component library, and even establish the enterprise production component library.
Wechat search official account: BIM Industry Alliance pays attention to us! 1、 Application of BIM Technology in quality management of standardized component manufacturing the main structural form of prefabricated buildings is the mode that prefabricated components are produced in the factory and then transported to the construction site for on-site hoisting construction.
2、 Application of BIM Technology in transportation quality management of PC components as prefabricated components need to be transported within a certain distance to the construction site to complete assembly after production, transportation is also an important link in the production and construction of prefabricated buildings and plays an important role in the quality control of buildings.
During the design of the lifting point position, attention shall be paid to the collision inspection to avoid the collision between the lifting point and the reserved hole.
Attention shall be paid to the accuracy of reserved parts and cavities to ensure that they are carried out in accordance with the design requirements and construction scheme, without affecting the development of subsequent processes.
3、 Application of BIM Technology in the storage quality management of PC components: after the prefabricated components arrive at the construction site, the layout of storage and hoisting shall be reasonably arranged according to the site conditions, and the construction facilities and equipment shall be reasonably arranged according to the production requirements.
Therefore, BIM Technology can play an important role in the hoisting nodes.
Before hoisting, the BIM building model can be used to simulate the construction scheme and fully reflect the construction process in three-dimensional form, which is convenient for the technical and operating personnel to carry out the actual operation and can also achieve the role of visual technical disclosure.
The traditional design scheme is mainly presented in two-dimensional drawing mode, while the main feature of BIM Technology is that visualization and information parameters are displayed in three-dimensional components, which is convenient for accurate design of components and avoids design errors.
The storage sequence is reasonably arranged according to the sequence of construction and hoisting.
From the early design, the category, size, location, quantity and other parameters of each component are coded and identified, and the coding is combined with RFID technology to realize the dynamic management of component production and transportation, and the BIM integrated management platform can be used to share component information, All relevant personnel can access the real-time production and location of components according to their authority, and use BIM Technology to carry out 3D mode transportation environment to avoid risks during transportation and ensure transportation quality.
Different kinds of prefabricated beams, plates, columns, stairs, internal and external wall panels and other practices are set to ensure the stability of design and production, facilitate the mass production of components, improve production efficiency, and speed up construction, It also has sufficient guarantee for quality stability.
As the hoisting components need to follow certain principles before they can be reasonably installed, there are special construction schemes for special nodes, and due to the diversity of component forms, the mechanization level is required to be higher, and the quality and safety are also required to be higher.
4、 The quality management application of BIM Technology in the hoisting process the biggest difference between prefabricated buildings and traditional buildings lies in the main work content of the construction site.
After the component information is input into the information system through the embedded chip, the component stacking and construction process can be directly simulated from the informatization software or platform, which is convenient for the operators to prepare and disclose the construction scheme.
In addition, management software and plug-ins for transportation planning can also be developed based on BIM Technology, and a transport moving line model can be established according to the production and construction address to analyze the number of transport vehicles, route conditions, transport vehicles and vehicle selection, so as to provide data reference for resource allocation.
In order to ensure that the prefabricated components produced by the factory meet the quality requirements, quality management should be carried out from the source, that is, quality control should be carried out from the design stage.
After BIM Technology and RFID technology are adopted in the preliminary design, component manufacturing, transportation and storage, the components have unique codes, and the classification and positioning are accurate, which is convenient for hoisting.
Meanwhile, attention shall be paid to the location arrangement of lifting points.
If the finished components are damaged due to improper transportation, on the one hand, it will cause rework and repair to affect the progress of the construction period, on the other hand, it will also bury hidden dangers for the quality and safety of the building.
The informatization function of BIM Technology in the storage link mainly lies in the identification and positioning of components.
In the transportation stage, BIM Technology can carry out information-based dynamic management of component information.
Therefore, it is necessary to pay full attention to the transportation of prefabricated components.
The traditional buildings mainly adopt the cast-in-situ method, while the construction site of prefabricated buildings mainly focuses on the hoisting process, that is, according to the design drawings and construction schemes, The hoisting work has an important impact on the quality of prefabricated buildings.
