China's earliest production and processing of aluminum veneer ceiling, one of the curtain wall manufacturers
Through the careful analysis of the node structure of the curtain wall project and the layout of the curtain wall separation diagram, and the key research on the position of the junction between the aluminum honeycomb plate and the plate end, that is, the center point of the meter shape, the theoretical research is combined with the repeated simulation installation practice on site, and the technical line of mold auxiliary measurement, flat ruler auxiliary installation and module fixed seam width is scientifically proposed, which solves the problems encountered in the installation of honeycomb plate and improves the installation, the installation quality is ensured, and the design intention of folding instead of bending is truly reflected, and the visual effect is natural, smooth and integrated.
2.2 Preparation for Installation
2.2.1 The establishment of internal and external measurement and control outlets of the main structure After the completion of the curtain wall vertical locking system of the performing arts center, the inside and outside cannot be seen through. The original measurement control points on the atrium and floor platform cannot meet the requirements of the aluminum honeycomb panel installation, measurement and setting-out work. We set up new measurement control points on the periphery of the performing arts center to start the work. According to the two coordinate reference points in the building, control network points are set up in the internal and external parts of the main structure with good terrain and good line of sight, and closed wires are formed.
2.2.2 Division of construction area and installation sequence
According to the curtain wall inspection batch division regulations and combined with the actual situation on site, the three slope curtain wall facade aluminum honeycomb panel grid control points are divided into 10 sections, 10 sections and 12 sections from bottom to top. section. The installation sequence of aluminum honeycomb panels with more than three layers in the whole performing arts center shall be symmetrical from south to north, and each area shall be constructed from bottom to top (Fig. 3) . Due to the uniqueness of each board, the aluminum honeycomb board is transported horizontally to the construction and installation area according to the board number on the board allocation diagram, and the aluminum honeycomb board is transported vertically to the corresponding installation position through the hoist.
In the construction preparation stage, we consult relevant information, similar engineering construction cases are few, and the analysis and summary of key technical difficulties are limited. Through the practice of this project and in combination with the characteristics of this curtain wall project, on the one hand, we actively communicate with the owner\'s curtain wall consultant company to fully understand the structure and structure design principles of this project; on the other hand, we comprehensively sort out the main materials, construction technology, machinery and equipment, construction organization, quality assurance measures and safety technical measures of the curtain wall of this project, and finally determine the best construction scheme and scientific management method after repeated research and analysis, Large venues metal curtain wall aluminum honeycomb panel positioning, installation control method has the characteristics of simple operation, flexible operation method, high construction efficiency and low cost, especially suitable for irregular, curved curtain wall decorative panel installation, to provide reference for similar projects in the future.
