The design intention echoes the natural landscape form of Jiuzhaigou.
Learn from nature and integrate into the landscape of Jiuzhai Paradise; Take the meaning of humanity and embody the cultural heritage with Sichuan Tibetan characteristics.
The equivalent stiffness method is adopted in the design of the flowering column, and the member analysis of the arc support is carried out to ensure safety.
▲ the original intention of project design for the application of different materials is to build a landscape architecture.
For the first time, small stone imitating star track pavement pattern is adopted in a large area, creating a model of special-shaped streamlined pavement.
The interior and exterior of the building fully reflects the connotation of Tibetan culture, the shape is relaxed and smooth, and integrates traditional culture and modern style.
▲ video of Goukou three-dimensional tourist service center in Jiuzhaigou scenic area on September 9, 2021, the completion acceptance of Goukou three-dimensional tourist service facilities in Jiuzhaigou scenic area was successfully passed.
▲ general plan ▲ aerial view because the project is located in Jiuzhaigou World Natural Heritage site and national scenic spot.
▲ the construction project of three-dimensional tourist service facilities at the mouth of Jiuzhaigou scenic area is located at the mouth of Jiuzhaigou scenic area, zhangzha Town, Jiuzhaigou County.
In addition, the project is in the collaborative design of “slate roof”, “flowering column” structure, “long-span mutually supporting glued wood structure” and “nonlinear building” “And other technical innovations.
The wood falling from the mountain after the earthquake is used for decoration, combined with the local slate and tile materials on the roof, to reflect the Tibetan cultural style with local characteristics in Jiuzhaigou.
Its emergence should not destroy the order of the original natural environment, but integrate into nature and respect nature.
During the peak hours of tourists, the platform layer and under the platform are used as the departure layer to help tourists quickly enter the ditch.
It is an “environmental building” rich in profound cultural heritage and integrating various management and service functions.
The summary of design methods through project research has a good guidance for the design of similar projects in the future.
Its design and construction level represents China’s latest technological achievements and strongest technological integration ability in engineering construction, and shows China’s comprehensive innovation ability to realize the integration of technological innovation in the field of basic design and construction of natural scenic spots in combination with advanced construction concepts and complex technical standards.
The project is located in Aba Tibetan and Qiang Autonomous Prefecture.
(2) The design method of glued wood structure is summarized through the research of this project: the mechanical characteristics of glued wood structure joints and components are deeply studied in the design process, and the design ideas and methods of glued wood structure are refined and summarized, which has a good guidance for the design of similar projects in the future.
A platform layer is set up, which is the main departure layer for tourists.
The distribution center makes full use of the elevation difference of the original site, which not only avoids many difficulties caused by the high groundwater level, but also creates a sense of closeness of the platform image.
The core column does not extend upward until 2.7m.
The flowering column of the tourist distribution center not only meets the architectural modeling requirements, but also meets the structural stress requirements, which is a model of the perfect combination of architecture and structure.
Due to the needs of architectural modeling, the project has many curved surfaces and curves from the structural system to the component level, with distinctive characteristics, and adopts a variety of innovative designs: (1) It is the first to adopt glued wood mutual supporting structure in China.
When the arc support reaches the height of the floor, steel beams are set to connect the 6 Arc supports as a whole, forming a space effect.
The entrance canopy and ticket screening mask shed of the distribution center have a span of 35-40m, which is the only project in China that adopts single-layer glued wood mutual supporting structure system.
During the implementation of the project, in cooperation with the architectural design, modeling and deliberation, Parameterized pavement texture.
From preliminary design, deepening, material selection, sample preparation to construction landing, GPS setting out is adopted for linear positioning of all star sky pavement to ensure the unity of completion effect and design effect..
The different colors of black, white and gray enrich the level of the star track, so as to echo the outline curve of the main building, and the mobility of the star track also plays a certain guiding role for tourists to enter the scenic spot.
At the same time, the support can effectively reduce the span of the steel beam and the height of the steel beam.
The distribution center makes full use of the elevation difference of the original site, which not only avoids many difficulties caused by the high groundwater level, but also creates a sense of closeness of the platform image.
The construction contents include: the construction area of new tourist service facilities is 26600 m2, the landscape and visitor square are 39700 m2 The building area of Heye hotel is 4049.84 ㎡, including the purchase of facilities and equipment, bridges and culverts, road works, tourist toilets, fire roads, greening and other ancillary facilities.
The first floor of the tourist distribution center is 5.5m high and the column spacing is 16m.
Pay attention to integration in the design With local cultural characteristics, Tibetan traditional building materials are used.
On the departure floor, you can enjoy the three mountains and two rivers at the mouth of the ditch, which becomes a prelude to entering the scenic spot.
The lower layer of the platform is slightly higher than the emerald river level, which is the main arrival layer for tourists.
▲ the bird’s-eye view design combines local materials, traditional technology and advanced digital technology, and uses the existing site conditions to create a natural and stretch architectural shape through landscape design, integrate into the environment and pay tribute to nature.
In order to effectively reduce the structural beam height and increase the clear height of the building, combined with the requirements of architectural modeling, a large number of frame columns adopt the form of flowering columns.
Tourists can enjoy the beauty of the ditch mouth on the departure layer Three mountains and two rivers are the prelude to entering the scenic area.
Traditional materials and architectural skills highlight the local culture, natural elements and shape, and pay tribute to nature and the future.
▲ single layer reticulated shell glued beam timber structure ▲ “canopy” Undulating like a mountain ▲ slate roof ▲ glued wood structure is an unconventional structural system – a structural system composed of 36 flowering columns.
The T-shaped column gradually becomes an arc-shaped H-shaped steel support according to the architectural modeling requirements.
