In the future, it will form a good situation of complementary functions and common development with the Capital Library, which will help give full play to the role of the capital's cultural vane, fully revitalize Beijing's cultural resources, improve the public cultural service system, meet the basic cultural needs of citizens, and become a sub-center of the city. , A physical think tank and a modern compound library that radiate the Beijing-Tianjin-Hebei region.

图书馆屋顶的树状建筑结构宛如森林伞盖，而筑起这片“森林”的，则是一款无龙骨全通透的超高玻璃幕墙。

The tree-like structure on the roof of the library is like a forest umbrella cover, and the building of this "forest" is an ultra-high glass curtain wall with no keel and full transparency.

图书馆项目即将投入使用的超高玻璃幕墙无论从外形还是受力体系上，都属国内首创，在国际上也并无先例。

这座超高玻璃幕墙由276块玻璃围绕而成，最高的玻璃高达15.05米，最大的板块重量达到10.77吨。

The super-high glass curtain wall that will be put into use in the library project is the first in China in terms of appearance and force system, and there is no precedent in the world.

This ultra-high glass curtain wall is surrounded by 276 pieces of glass. The tallest glass is 15.05 meters high and the largest plate weighs 10.77 tons.

外立面首块高15.33米、宽2.63米、重量超过11.5吨的超大玻璃幕墙开始吊装，整个项目将安装276块，提升图书馆采光能力，打造“透明书苑”。

The first super-large glass curtain wall of 15.33 meters high, 2.63 meters wide, and weighing more than 11.5 tons began to be hoisted. The entire project will install 276 blocks to enhance the library's daylighting capacity and create a "transparent library".

外立面超大玻璃幕墙的作用，不仅是为了使图书馆造型新颖、个性鲜明，更为了最大限度提升采光能力。

The function of the large glass curtain wall on the facade is not only to make the library novel and distinctive, but also to maximize the lighting capacity.

超大玻璃幕墙运输到施工现场时，更要拆除围挡，确保入场安全。

在正式安装前，项目部已多次展开专家论证，多次进行安全施工系数测试，以确保运输、存放精准安全。

除了运输、存放难度大，在安装玻璃的打胶过程中，需要在无尘封闭场所中，采用纯手工工艺。因此，项目部定制了一个巨大的无尘箱体辅助施工。玻璃吊装就位后，工人将在箱体中给玻璃打胶。

When the super-large glass curtain wall is transported to the construction site, the fence must be removed to ensure safe entry.

Before the formal installation, the project department has carried out expert demonstrations for many times and conducted safety construction coefficient tests to ensure accurate and safe transportation and storage.

In addition to the difficulty of transportation and storage, in the glueing process of installing the glass, it is necessary to use pure manual craftsmanship in a dust-free closed place. Therefore, the project department customized a huge dust-free box for auxiliary construction. After the glass is hoisted in place, the worker will glue the glass in the box.

这座“森林书苑”内部，将呈现“山谷门厅”的景致。在南北大门之间，有一条蜿蜒的主通道，两侧的区域形似山坡上的梯田，每一层都可供市民阅读休闲，让读者仿佛置身于森林环抱的山谷之中。图书馆外，就是城市绿心森林公园。

The interior of this "Forest Book Garden" will present a view of the "Valley Foyer". Between the north and south gates, there is a meandering main passage. The areas on both sides are shaped like terraces on the hillside. Each floor is available for citizens to read and relax, making readers feel like they are in a valley surrounded by forests. Outside the library is the Urban Green Heart Forest Park.

The design of the "Valley Hall" integrates the forest landscape with the book reading area to form a very friendly public open space. The existence of the large glass curtain wall allows readers to see the outside landscaping landscape in any public area of the library, and enjoy the reading experience of "between the mountains and under the trees".

The city’s sub-central library has functional areas such as ancient books, intangible cultural heritage, open-shelf reading area, smart library, lecture hall, etc. The daily reception volume is about 5,000 to 8,000 people. It is planned to be completed and accepted by the end of December 2022.
