by 1、 The application of BIM Technology in the quality management of standardized component manufacturing the main structural form of precast buildings is the mode that precast components are produced in the factory and transported to the construction site for on-site hoisting construction.
Therefore, compared with the traditional construction and production mode, the primary production link of precast buildings is carried out in the factory.
In order to ensure that the precast 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.
The traditional design scheme is mainly presented in two-dimensional drawing mode, while the main feature of} BIM Technology is visualization and unified display of information parameters in three-dimensional components, which is convenient for accurate design of components and avoid design errors.
At the same time, at this stage, the hoisting points shall be reasonably set in the precast components according to the requirements of relevant specifications and standards, so as to facilitate the on-site hoisting construction of components in the later stage.
When designing the lifting point position, pay attention to the collision inspection to avoid the conflict between the lifting point and the reserved hole.
Because the important feature of precast building components is standardized production, the standardized design can be carried out through BIM Technology in the design, the component information can be presented completely, and the information data can be directly connected with the component manufacturer to improve the efficiency of design and component production.
The reason why BIM Technology can realize fast and accurate design is that it has a relatively complete family library.
Designers can carry out secondary development on the basis of software family library, continuously improve the component library, and even establish enterprise production component library.
Different kinds of precast beams, plates, columns, stairs, internal and external wall panels are set to ensure the stability of design and production and facilitate mass production of components, Improving production efficiency and accelerating construction speed also have sufficient guarantee for quality stability.
2、 Application of BIM Technology in the quality management of PC component transportation # since the precast components need to be transported within a certain distance to the construction site to complete the assembly work after production, transportation is also an important link in the production and construction of precast buildings and plays an important role in the quality control of buildings.
If the components completed in production are damaged due to improper transportation, on the one hand, it will cause rework and repair, affect the construction schedule, on the other hand, it will also bury hidden dangers for the quality and safety of the building.
Therefore, we should pay full attention to the transportation of precast components.
In the transportation stage, BIM Technology can carry out information-based dynamic management of component information, code and identify the category, size, location, quantity and other parameters of each component from the preliminary design, and combine the coding with RFID technology to realize the dynamic management of component production and transportation, and share component information using} BIM integrated management platform, 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, so as to avoid risks in the transportation process and ensure the transportation quality.
In addition, we can also develop management software and plug-ins in transportation planning based on BIM Technology, establish transportation moving line model according to production and construction address, analyze transportation vehicle number, route, transportation vehicle and vehicle selection, and provide data reference for resource allocation.
3、 Application of BIM Technology in storage quality management of PC components after the precast 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 demand.
At the same time, it should 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 construction in the storage link, For overweight and oversized components, the site reinforcement treatment shall be considered, and the component turnover space shall be reserved for the position of hoisting machinery in the later stage.
The informatization function of BIM Technology in the storage link mainly lies in the identification and positioning of components.
The storage sequence is reasonably arranged according to the sequence of construction and hoisting.
After the component information is input into the information system through chip implantation, it can directly operate and simulate the process of component stacking and construction from the information software or platform, It is convenient for operators to prepare and disclose the construction scheme.
4、 Quality management application of BIM Technology in hoisting process the biggest difference between precast buildings and traditional buildings lies in the main work content on the construction site.
Traditional buildings mainly adopt cast-in-situ method, while the construction site of precast buildings mainly focuses on hoisting technology, that is, lift each component to the designated position for on-site installation or connection according to the design drawing and construction scheme, Therefore, in the construction link, the hoisting work has an important impact on the quality of precast buildings.
As certain principles need to be followed in hoisting components before reasonable installation, there are special construction schemes for special nodes, and due to the diversification of component forms, there are higher requirements for mechanization level and higher requirements for quality and safety.
Therefore, BIM Technology can play an important role in hoisting nodes.
After the BIM Technology and RFID technology are adopted in the preliminary design, component manufacturing, transportation and storage, the components have a unique code, and the classification and positioning are more accurate, which is convenient for hoisting.
Before hoisting, the construction scheme can be simulated through BIM building model to fully reflect the construction process in three-dimensional form, which is convenient for technicians and operators to carry out actual operation, and can also achieve the role of visual technical disclosure.
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.
At the same time, attention shall be paid to the location arrangement of lifting points, and lifting points shall be carried out according to relevant safety operation specifications to ensure the safety of lifting construction..
