Background
Cross-glued wood is an engineered wood product invented in europe in the early nineties of the twentieth century. With decades of development, the solar energy heat collector is popular worldwide and is increasingly used in some residential buildings and non-residential buildings. The orthogonal laminated wood is generally formed by vertically and symmetrically assembling laminated solid wood sawn timber or engineering wood (at least 3 layers) and then gluing the assembled components by using a structural adhesive, and is a prefabricated engineering wood product with good bidirectional mechanical property and high strength.
Compared with solid wood, the cross-glued wood has good dimensional stability. The orthogonal structure of adjacent layers of the orthogonal laminated wood results in the same dry shrinkage and wet expansion performance in the main direction and the secondary direction of the material. The research shows that the linear dry shrinkage and wet expansion coefficient of the orthogonal laminated wood is 0.02 percent, and the dimensional stability of the orthogonal laminated wood is 12 times of the dimensional stability of the cross grain direction of the solid wood and the laminated wood.

In this embodiment, the engineering wood beam 2 is rigidly connected with the orthogonal plywood 1, so that the floor load can be effectively transmitted to the engineering wood beam 2, and the overall mechanical property of the floor is improved. Specifically, when the orthogonal laminated wood floor with the composite structure is prefabricated in a factory, the orthogonal laminated wood floor 1 and the engineering wood beam 2 are in rigid connection by adopting an adhesive. When the orthogonal plywood 1 and the engineering wood beam 2 are assembled on a construction site, a rigid connection is formed by adopting a metal fastener. Wherein, the metal fastener is L-shaped metal connecting piece and self-tapping screw.
In the prior art, the orthogonal laminated wood can be directly used as a floor slab with a wood structure, the span of the floor slab depends on the number of layers of the orthogonal laminated wood 1, but the number of layers is directly increased, so that the weight of the floor slab is obviously increased, therefore, an additional upright post needs to be additionally arranged at the middle position below the floor slab to support the floor slab and improve the load of the floor slab, the design requirement is met, the building cost is increased, the use of a building space is limited, and the design difficulty is increased.
