Vall d’Hebron Hospital
设计方：Estudi PSP Arquitectura
位置：西班牙
承包人：HL y G&O, UTE Vall d’Hebron
工程师：GRUPO JG Ingenieros
项目规模：15,802平方米

这是综合医院内建设的一个独特项目，需要提供完成不同外科手术以及术后康复的场地，以及设计一个垂直公共交通核心筒以提高病人的转移效率，解决与外来人流的交叉流线问题。
为了解决瓦尔德希伯伦医药学院缺乏可用空间、以及与医院群的外科手术部、ICU部缺乏明显的功能联系这两个问题，建筑师提供了在现存建筑背后及上面新增两座医药功能区及技术功能区的设计方案。
处于结构上的考虑，建筑师设计了一个建设性的解决方案，新建筑并不将任何垂直载荷传到旧建筑的结构上，但会利用它作为支撑核心。因此，新建筑的地板采用了旧建筑楼外的柱子支撑，大跨度的梁（7M及26.4米长）直接暴露在外，与旧建筑外墙平行。而其他主梁支撑起旧建筑上方的悬挂厚板形成一座桥，防止载荷传达到现存建筑。
新建的垂直核心交通筒（11层高），坐落在建筑中心的庭院之一，连接所有楼层的住院部以及带有外科手术室和重症监护房的急诊部，与外来人流的流线分开。
建筑外墙采用了大幅面夹心板，采用的钢材与建筑外露结构的颜色相近。建材多选择轻型、便于干法施工的，以减轻建筑重量、削弱施工期间对低楼层的干扰。

This is a unique project in the General Hospital building. The intervention arises from the need to rationalize and concentrate the different surgical and post-operation recovery areas, as well as the desire to create a new vertical communication core to expedite the transfer of patients and solve the crossed circulation with the public.
Given the lack of free space within the Medical Campus of Vall d’Hebron and the apparent functional need to connect the new surgical and ICU areas with hospitalizations areas, the option of placing two medical plans and a technical plan above the back wings of the existing building was raised.
For structural reasons, we design a constructive solution that does not transmit any vertical loads onto the structure of the old building, but uses it as a bracing core. Thus, the new slabs are supported by pillars outside the building, and large span girders (7m and 26.4 m), parallel to the facades, remain exposed outside of the enclosures. On these, perpendicular and at the technical plan level, others girders are supported, from which hang the pillars that hold the slabs, thus forming a bridge that prevents the transmission of loads onto the existing building.
The new vertical core (11 stories high) is located in one of the courtyards, at the center of gravity of the building, connecting all the hospitalization floors and emergency with the new surgical and critical care units block, without crossing with the public circulation.
The enclosures are designed with large format sandwich panels, made of lacquered steel similar in color to the exposed structure of the building. In general, all materials used are light and for dry construction, minimizing weights and inconvenience to the lower floors, which have remained in use at all times.
Because of the difficulty involved in the execution of projects of this magnitude in a hospital in use, due to the the growing medical and technological demands, and the needs to update certain facilities of the existing building, we have proposed an amended project and four complementary projects during the construction, delaying its execution time.
