NCCLT (NC cross-laminated timber) insulation panel and method of connecting same to foundation

Abstract

The invention provides an NCCLT (NC cross-laminated timber) insulation panel and a method of connecting the same to a foundation. When the number of the layers of vertical boards of the NCCLT insulation panel is an odd number, connecting is achieved via T-shaped embedded connectors, odd board groove embedded connectors, steel plate and wedge T-connector connectors or odd board groove steel plate and wedge connectors; when the number of the layers of vertical boards of the NCCLT insulation panel is an even number, connecting is achieved via even board groove embedded connectors or even board groove steel plate and wedge connectors. The NCCLT insulation panel and the method of connecting the same to the foundation have the advantages that the NCCLT insulation panel is prefabricated completely in a factory, durability is significantly improved, the ecological environment is not damaged, the yield is greatly increased, sound insulation and heat insulation are integrated, inner pores are maximized, the rigidity and strength of the NCCLT insulation panel are greatly improved, the consumption of material is reduced, excellent stress-bearing property is provided, and the NCCLT insulation panel has incomparable ability to restore from deformation; the cost of building houses with NCCLT is low, processing is simple, construction is convenient, mounting efficiency is greatly improved, andmanufacturing cost is reduced.

Description

technical field [0001] 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 [0002] 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 str...

Problems solved by technology

[0007] 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

④Insulation, sound insulation and other materials cannot be integrated, increasing on-site procedures, prolonging the construction period, and increasing costs
