静冈新闻·静冈放送株式会社东京分公司翻新项目 / 大成建设

项目亮点：本项目最引人注目的在于对1967年建成的现代主义建筑的保护与更新。这座由丹下健三设计的建筑，是新陈代谢建筑的典范，象征着日本战后经济的快速发展。翻新工程不仅保留了建筑的独特外观和结构，更融入了现代化的功能与需求。通过精细的结构分析，设计团队有针对性地进行了抗震加固，确保了建筑在地震中的安全性。同时，对原有立面色彩的精确还原，体现了对历史文脉的尊重，也为这座建筑注入了新的生命力，使其在现代社会中焕发新生。

技术精髓：本次翻新项目展现了卓越的结构加固技术。针对独特的圆柱形核心筒结构，设计团队采用了创新的碳纤维板和薄钢板加固方案。碳纤维板用于柱腿的弯曲加固，薄钢板则作为剪切加固，从而显著提高了建筑的抗震性能，且最大程度地保留了建筑的原有形态。此外，项目中采用的3D扫描技术和精细的油漆颜色比对，也体现了对细节的极致追求。这些技术手段的综合运用，使得建筑在满足现代使用需求的同时，也实现了对历史遗产的有效保护。

设计理念：该项目体现了对新陈代谢建筑理念的深刻理解与实践。翻新不仅仅是简单的修复，更是在保留原有价值的基础上，赋予建筑新的功能和生命力。设计团队注重现代用户的需求，增强安全性，实施业务连续性计划，并提供无障碍通行，创造出更舒适、友好的工作环境。同时，通过照明设计，强调建筑的夜间存在感，使其成为当地的标志性建筑。这种注重历史传承与现代需求的平衡，使得这座建筑得以延续其价值，并继续服务于未来。

The project involves the protection and restoration of a modernist building built in 1967, located in Ginza, Tokyo, which is considered a model of metabolic architecture. This building is a unique work by one of Japan's most famous architects, Kenzo Tange, who designed a creative new form on a small plot of land to symbolize Japan's rapid post-war economic growth. The cylindrical core in the center of the building accommodates vertical transportation routes such as stairs, elevators, and pipelines. The office space protrudes outward from the core, giving it a unique appearance.
该项目涉及保护和修复一座建于 1967 年的现代主义建筑，位于东京银座，被认为是新陈代谢建筑的一个典范。这座建筑是日本最著名的建筑师之一丹下健三的独特作品，他在小型地块设计了一个象征日本战后经济快速增长时期创造性的全新形式。建筑中央的圆柱形核心容纳了垂直交通路线，如楼梯、电梯和管道。办公空间从核心向外突出，赋予了其独特的外观。

The painting work on the exterior walls was renovated in 1993, and the internal facilities and exterior were renovated in 1999. This time, the structure and function have been reinforced and renovated as a whole to extend the service life of the building for decades.
外墙的油漆工作于 1993 年进行了翻新，内部设施和外部于 1999 年进行了翻新。这一次结构和功能得以加固以及整体翻新，以延长建筑的使用寿命数十年。

Given the unique structural system, the updated plan has undergone seismic reinforcement, while identifying weak points in the building through seismic response analysis to minimize the required space. Carbon fiber board is used as a bending reinforcement material attached to the column legs of the cylindrical core wall from the inside (approximately one layer), and thin steel plates are installed as shear reinforcement in the lower layers (from one to five layers). This significantly improves the seismic resistance while maintaining the original form of the building, and ensures the availability of small spaces.
鉴于独特的结构系统，更新计划进行了抗震加固，同时通过地震响应分析识别建筑的薄弱点，从而最小化所需空间。碳纤维板作为弯曲加固材料从内部附着在圆柱核心墙的柱腿上（大约在一层），并在下层（从一层到五层）安装了薄钢板作为剪切加固。这使得在保持建筑原始形态的同时，显著提高了抗震能力，并确保了小空间的可用性。

On the exterior of the building, the design team conducted a paint inspection on the walls inside and outside the columns to reproduce the original color during construction. The team checked the painting history of the exterior wall inspection points and compared the colors with photos taken during the construction period to identify the colors.
在建筑外部，设计团队对圆柱内外的墙壁进行了油漆检查，以重现建设时的原始颜色。团队检测了外墙检查点的涂刷历史，并与建设时期的照片进行了颜色对比，以识别颜色。

In addition, the bottom and cylindrical shape of the eaves are illuminated, and LED lighting is introduced indoors. This changes the appearance of the building at night, emphasizing its existence as a local landmark both during the day and at night.
此外，檐口的底部和圆柱形状被照亮，室内引入了LED照明。这改变了建筑在夜间的外观，不论是白天还是夜晚，都强调了其作为当地地标的存在。

In terms of interior and facilities, the design team focuses on reflecting the needs of today's users. Specifically, the updated plan enhances security, implements Business Continuity Plan (BCP) measures, ensures barrier free access, and adds new shared spaces, achieving a more comfortable and user-friendly work environment.
在室内和设施方面，设计团队专注于反映当今用户的需求。具体而言，更新计划增强了安全性，实施了业务连续性计划（BCP）措施，确保无障碍通行，并增加了新的共享空间，达成了更舒适和用户友好的工作环境。

The most important focus of this project is to determine which areas need renovation, which areas need protection, and record the history of each area before restoration. This metabolic architecture will not only add new functions and value, but also pass on to the next generation.
该项目最重要的重点是确定哪些区域需要翻新，哪些区域需要保护，并在修复之前记录每个区域的历史。这种新陈代谢式的建筑将在增添新功能与价值的同时，传承给下一代。
