The first
High-rise building using "wood-concrete combination structure"
Construction was completed in the Jiangsu Provincial Rehabilitation Hospital Project of China Construction Fifth Bureau East China Company
!
Wood structure
is an important representative symbol of Chinese traditional architectural culture.
my country has a long history in the research and application of wood structures.
The low-carbon, degradability and renewability of wood,
also makes it a A recognized green building material.
▲Wood-concrete composite structure construction
Under the background of the national "dual carbon" strategic goals and requirements,
0 In response to the development concept of green construction,
Promote new materials and new technology applications, l3 focuses on the research and exploration of prefabricated wood structures, China Construction Fifth Bureau East China Company Jiangsu Provincial Rehabilitation Hospital Project on the roof structure 5th floor top and 7-8 layers, is the first in the country to in multiple high-rise buildings Areas use wood-mixed structures. Recently, the project roof wood-mixed structure prefabricated components have been fully hoisted, and 3 marks the completion of the construction of the wood-concrete structure . rare "wood-concrete combination structure" construction See how it is constructed ▲wood-concrete combination structure process video Wood-concrete structure innovation application help low Carbon buildings and zero-carbon buildings are fully implemented Jiangsu Provincial Rehabilitation Hospital project wooden structure overall application area is about 18,000 square meters, with a volume of about 3,000m³, This all-solid wood material, is called "Breathable house" . replaces traditional concrete with wooden structures. can absorb greenhouse gas about 1200t, 01 CO stored in wood ₂ about 3100t,
1 CO ₂ about 3100t,
overall potential carbon benefits are about 4300t,
is equivalent to about 900 cars in a year's carbon emissions ,
has very important practical significance for the development of the dual-carbon strategy.
The first
Wood-concrete combination building
In the wood-concrete structural system,
East China Company innovatively adopts the combination of
up and down and horizontally mixed 1.
Steel components are embedded with wooden columns and
. Vertical and horizontal mixed structure innovation is effectively connected to each other.
further enhances the stability of the wood-concrete structure, and
0 and realizes the stability of the wood-concrete structure through repeated simulation research. Under the background of innovation,
structure and fire protection design both meet the specification requirements.
is the first in China to pass the construction drawing review.
new wood structure material
is the only renewable main building material
Among the top ten low-carbon buildings in the world in 2021, there are 3 foreign buildings built using the same CLT board as the Jiangsu Provincial Rehabilitation Hospital. GLT (glued wood) beams and columns, NLT boards (laminated wood),
CLTh boards (orthogonal glued wood) referenced by
CLTh boards (orthogonal glued wood) are representatives of new lightweight green building materials.
excellent strength and weight makes wood structure reach steel Structure,
The concrete structure has the same strength effect ,
Its self-weight is lighter and space transformation is more flexible.
At the same time, the wood structure per unit volume is processed and produced
1 The fossil fuel energy used is greatly reduced,
1 This means that the wood has an ultra-low carbon footprint.
▲roof wood structure
revival of excellent traditional culture
enhance environmental protection
East China Company will continue to implement the dual-carbon strategy
Follow the sustainable development with actions
Building green and ecological "future building"
