Abstract

The invention provides a novel CLT (Cross-laminated Timber) board adopting a saw-tooth-shaped interlaminar gluing manner. The novel CLT board is composed of a core layer and a surface layer, wherein each of the core layer and the surface layer is provided with a corresponding concave (convex) groove; the CLT board is commonly formed by gluing odd layers of panels; the middle core layer is formed by laminating a panel with the concave (convex) grooves in two faces and core layers which are provided with the concave (convex) grooves in two adjacent faces and are located at two sides; the layersare laminated in sequence according to the panel layers needed by the engineering through the manner until the final surface layer is laminated with the adjacent core layer by adopting the concave (convex) groove at the single side; in a lamination process, the concave grooves and the convex grooves (the convex grooves and the concave grooves) of the adjacent panels are embedded together; and allthe panels are orthogonally glued together by utilizing an epoxy resin structure adhesive. Compared with an existing gluing manner, the novel CLT board has the advantages that the panels of all the layers are arranged in a manner of embedding of the concave and convex grooves and the panels can be more tightly connected and are not easy to peel off, so that the whole performance of the CLT board is improved.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering and construction, and relates to building components, in particular to a novel CLT board in a zigzag interlayer glued mode. Background technique

[0002] The application and research of CLT panels in building structures has been favored at home and abroad in recent years. The CLT board is formed by orthogonal gluing between adjacent panels, and it has the same dry shrinkage and wet expansion performance in the primary and secondary directions of the material, so its dimensional stability is 12 times that of solid wood and other glued wood. ;Due to the particularity of its tissue embryo, its rolling shear performance is low; compared with the traditional light frame construction, the cross-sectional size of CLT building components is larger, and the surface carbonization forms an insulating protective layer during combustion, which effectively improves its performance in Bearing capacity...
