The two scientific and technological achievements of the group have reached the domestic leading level
On April 1, the Beijing Municipal Commission of housing and urban rural development appraised the scientific and technological achievements of the group's "research and application of construction technology of super large ceramic decorative panels" and "research and application of integrated technology of three-dimensional scanning and holographic image of old buildings". Relevant leaders of the science and Technology Department of Beijing Municipal Commission of housing and urban rural development, urban construction group and Wang Zhenxing, chief engineer of the group attended.
The experts of the appraisal committee listened to the report of the research group and reviewed the relevant appraisal materials. After questioning and discussion, they unanimously agreed to pass the appraisal, and both achievements reached the leading level in China.
Relying on the fine decoration phase I project of Chengao building of Zhongbang decoration company, the research group of construction technology research and application of super large ceramic veneer carries out research and Application on the technical problems in the construction of super large ceramic veneer. Based on the analysis and comparison of various installation methods, the dry hanging method is developed and the dry hanging system is designed, which effectively solves a series of technical problems such as the production, transportation, installation and finished product protection of super large ceramic decorative panels; The reinforcement technology of aluminum frame back rib of super large ceramic decorative panel has been developed to enhance the overall stiffness of the plate and ensure the construction safety; Factory production and on-site unit dry hanging technology are adopted to improve the construction efficiency and ensure the installation accuracy.
Based on the reconstruction project of CRRC 27th plant-6-dof training hall, the research group of "research and application of integration technology of three-dimensional scanning and holographic image of old buildings" has studied and applied the integration technology of three-dimensional scanning and holographic image of old buildings in conjunction with Guangzhou sikan surveying and mapping Co., Ltd., which can provide reference for the digital survey of old building reconstruction project. This technology optimizes the data accuracy and collection efficiency of 3D point cloud and panoramic model, and provides technical support for rapid recording and comprehensive archiving for architectural heritage protection, renewal and transformation; Developed the real-time switching technology between panoramic image and 3D point cloud, realized the lightweight application of data query, and saved human, financial and time costs for architectural transformation design; Through the conversion technology between 3D point cloud and 2D mapping drawing, an interface is reserved for docking BIM platform.
In this scientific and technological achievement meeting, the group organized and completed complete technical materials, with strong innovation, significant economic and social benefits, which met the appraisal requirements and the needs of industry development. The experts of the appraisal committee affirmed the scientific and technological research and development work of the group and encouraged the scientific and technological personnel to make further efforts to continuously promote the technological innovation of the industry.
