NCCLT (NC cross-laminated timber) Insulation plate with door opening and connection method thereof

Abstract

The invention provides an NCCLT (NC cross-laminated timber) insulation plate with a door opening, comprising an NCCLT insulation plate with a door opening in the flat end, an NCCLT insulation plate with a door opening in the single stepped end, and an NCCLT insulation plate with door openings in the double stepped ends. The NCCLT insulation plate with the door opening in the flat end is formed ofa plurality of plies, each ply is composed of multiple dimensioned wood blocks, and parallel grains of the adjacent plies are perpendicular to each other; the inner and outer plies are continuous longitudinal plies, a plurality of longitudinal wood plies having an inner cavity and a plurality of transverse wood plies having an inner cavity are arranged between the two continuous longitudinal plies. One end of each of the top and bottom continuous longitudinal plies of the NCCLT insulation plate with the door opening in the flat end is provided with a connection stepped edge. The NCCLT insulation plate with the door opening has the advantages that factory premanufacturing is completely achieved, durability is significantly improved, no damage is caused to ecology, the yield is greatly increased, sound insulation and heat insulation are integrated, inner holes are maximized, the rigidity and strength of the plate are greatly improved, material consumption is reduced, and the plate has excellent load-bearing capacity and incomparable ability to restore from deformation.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an NCCLT insulation board with a door opening and a connection method thereof. 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 struct...

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
