Hollow cross-ply laminated building block bearing plate

Abstract

The invention relates to a hollow cross-ply laminated building block bearing plate which comprises an inner layer plate body and an outer layer plate body. At least two heat preservation or sound insulation layers are arranged in a first cavity formed between the inner layer plate body and the outer layer plate body. Each heat preservation or sound insulation layer comprises first wood boards arranged at the two ends of the first cavity, and second wood boards arranged in a cavity between the two first wood boards at intervals, cavities formed between every two second wood boards and between the first wood boards and the second wood boards are filled with non-bearing heat preservation boards or non-bearing sound insulation materials, a second cavity is formed between every two heat preservation or sound insulation layers, and third wood boards are arranged at the two ends of each second cavity respectively. The hollow design is adopted, and the heat preservation or sound insulation layers are embedded in plate bodies, so that good heat preservation performance or sound insulation performance is achieved, and heat preservation protection or sound insulation treatment does not need to be carried out outside the plate bodies any more; the boards in the plate bodies are distributed in a cross-ply mode, so that the plate bodies have good stress performance and are light and good in economic effect, the manufacturing cost is reduced, and environment pollution is effectively avoided.

Description

Technical field: [0001] The invention relates to the technical field of building structures, in particular to a hollow orthogonally laminated wood load-bearing board. 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, consumes a lot of energy, causes ecological imbalance, and at the same time produces 24% of the world's air Pollution, 50% of the greenhouse effect, 40% of water pollution and 50% of chlorofluorocarbons, etc., have had a bad impact on human life. [0003] In the past, people paid more attention to steel structures and concrete structures while ignoring green buildings with wooden structures. However, with the development of the construction industry, the non-renewable and unsustainable nature of steel, cement, and plastics has become very obvious. It plays a vital role in arranging and adjusting the industrial structure, bec...
