Description

NCCLT insulation board and its connection method with the foundation

technical field

The invention belongs to the technical field of construction, and in particular relates to an NCCLT thermal insulation board and a method for connecting it to a foundation.

Background technique

According to statistics, the construction industry consumes about 50% of the earth's energy, 42% of water resources, 50% of materials and 48% of arable land. Cause ecological imbalance, resulting in 24% of global air pollution, 50% of greenhouse effect, 40% of water pollution and 50% of chlorofluorocarbons. With the continuous development of modern wood structure technology and wood treatment technology, a series of problems such as fire prevention, moisture resistance, corrosion resistance, ant resistance, and sound insulation have been completely solved, so that wood can face any architectural challenges, and in terms of design life and service life, Wood frame houses are much longer than concrete frame houses. The continuous development of wood structure and its industrialization has enabled my country's construction industry to truly realize the whole process of green, recyclable and sustainable. Therefore, ancient and modern wooden structures are beginning to gradually return to the center stage of the construction industry. The main reason is that wooden structures have great advantages in sustainable development: ① Green: Every cubic meter of wood grown in a forest can absorb about 850 carbon dioxide Kilogram. The production of 1 cubic meter of steel emits about 12 tons of carbon dioxide, and 1 cubic meter of concrete emits about 3 tons of carbon dioxide. ②Health: The indoor air of wooden structures contains a large amount of phytoncide and negative ions called air vitamins, which are beneficial to people's physical and mental health. ③ Energy saving: The thermal insulation and energy saving performance of wooden structure houses is better than any other structural forms. The thermal insulation value of wood is 16 times higher than concrete, 400 times higher than steel, and 1600 times higher than aluminum. ④Environmental protection: Wood is a natural growth material, and the production of steel and cement causes air and water pollution. ⑤Seismic performance: wood structure has superior flexibility, good ductility and energy dissipation capacity. Even when strong earthquakes knock entire buildings off their foundations, their structures often remain intact. Wooden structures have high toughness, strong resistance to instantaneous impact loads and periodic fatigue damage, and have the best seismic resistance among all structures, which has been fully proved in many large earthquakes. ⑥Durability: Wood is a stable, long-lived and durable material. Many ancient wooden buildings in our country have experienced wind, frost, snow and rain for thousands of years, and they are still standing. A large number of wooden houses in foreign countries have been used for hundreds of years and still play a good use function. ⑦Fire resistance: The fire-resistant wood structure has a carbonization effect, and its low conductivity can effectively prevent the flame from spreading inward, thus ensuring that the entire wood structure will not be damaged for a long time. ⑧Flexible design and high utilization rate: Compared with steel structure, concrete structure and masonry structure, wood structure has the most diverse connection forms, the most flexible space layout and the highest utilization rate. ⑨Construction: The construction period of the wooden structure is the shortest, and it is not affected by the climate, and can be constructed at any time.

Wooden structure buildings not only have huge sustainable development advantages, but also have huge industrialization advantages: ① High assembly rate: it is difficult for concrete structures to exceed 80%, while wood structures can reach 100%. ② High rate of standardization and generalization: wood structure has a single material, and the degree of standardization and generalization is higher than that of concrete structure. ③ High level of automation in the workshop: The wood structure has strong machinability, and the automation rate of the workshop component production is much higher than that of the concrete structure. ④Low processing cost: wooden structural components do not need moulds, pouring and maintenance, and processing saves time, labor and money. ⑤ High processing precision: The process of processing wood structures is controlled by machine tools with high processing precision. ⑥ Low transportation cost: The wooden structure is not only light in weight, but also more regular in shape, without a large number of exposed steel bars. ⑦ Fast assembly speed: Assembling concrete structures still requires a lot of wet work, compared with that, the construction period of wooden structures can be shortened several times. ⑧Low requirements for workers: Concrete structure assembly requires a large number of high-quality professional teams, a large number of precise operations, grouting and cast-in-place. In particular, a large number of steel bars are connected, and the operation is difficult. And the installation operation of the wooden structure is significantly simplified. ⑨Assembly of major parts: Since the wooden structure is lighter and more regular, it can be assembled with major parts, and the degree of industrialization is higher.

Cross-laminated timber (CLT) is a new type of wood building material. It uses kiln-dried specification finger-jointed timber to be sorted and cut into wooden squares. The area and thickness can be customized according to requirements; its characteristic is that the standard wood with horizontal and vertical grains is glued together, and its strength can replace concrete materials. The relevant tests show that the wooden buildings made of this material have good seismic performance.

CLT has a strong load-bearing capacity in nature, and it can be used as an important load-bearing material in both vertical and horizontal combined applications. Theoretically, CLT can be used as a structural material for timber buildings up to 10 stories high, and as a substitute for cement or steel.

CLT is a heavy-duty wood structure. Large-area cross-laminated wood panels can be cut directly and used as exterior walls, floor slabs, and roof panels of buildings. They are suitable for buildings above the ground; because this technology has the advantages of efficient and high-speed construction, And it has low requirements on the weather, which can greatly improve the construction progress. CLT has inherently excellent fire resistance, which is similar to the characteristics of heavy wood structures: once a fire occurs, the surface layer of CLT wood materials will slowly carbonize at a certain rate and at the same time maintain the original internal structural strength for a long time. Therefore, this carbonization effect can further ensure the structural strength of the board. In areas with frequent earthquakes, the key consideration in the safety design process is the seismic capacity of the structural system. As a building material, CLT, together with other connectors and fasteners used in construction, ensures that the overall structure has strong earthquake resistance. The material is natural, green and environmentally friendly, and can greatly reduce greenhouse gas emissions throughout the life cycle; it has low requirements for construction conditions, fast construction and installation, and saves construction time, thereby reducing costs; compared with traditional building materials, the material is light and the requirements for the foundation are not high. It is beneficial to speed up the construction progress and reduce the cost; the wood structure building with cross-laminated wood has excellent fireproof and earthquake resistance performance.

However, CLT also has its own shortcomings: ①The stability period of the structural adhesive used is often only 50 years, and the stability period of some structural adhesives is less than 20 years, while the life span of wood structure buildings is often hundreds or even thousands of years. The stability of the glue seriously affects the durability of the structure. ② Extensive use of structural adhesives is not only harmful to health, but also causes certain damage to the environment. ③ When wood is glued, its surface needs to be as flat as a mirror, and the yield of wood is significantly reduced. ④Materials such as thermal insulation and sound insulation cannot be integrated, which increases on-site procedures, prolongs the construction period, and increases costs.
