Orthogonal laminated wood-concrete composite floor and reinforcing method
The invention discloses an orthogonal laminated wood-concrete composite floor. The orthogonal laminated wood-concrete composite floor comprises a concrete plate, a CLT plate, a plurality of pneumatic strip nails and a plurality of wood cushion blocks; the plurality of wood cushion blocks are arranged on the first surface of the CLT plate, the plurality of pneumatic strip nails penetrate through the wood cushion blocks from the upper surfaces of the wood cushion blocks and are inserted into the CLT plate, and an included angle exists between the insertion direction of the pneumatic strip nails and the vertical direction; and the concrete plate is poured on the first surface of the CLT plate, the wood cushion blocks and the pneumatic strip nails. The pneumatic strip nails are driven into the wood cushion blocks and the CLT plate so that the interlayer shearing capacity of concrete and the CLT plate can be remarkably improved, the interlayer shearing capacity of all layers of the CLT plate and the rolling shearing capacity of the CLT plate are improved, the application range of the orthogonal laminated wood-concrete composite floor is convenient to popularize and expand, and the development of a multi-story and high-rise wood structure is promoted; and meanwhile, according to the orthogonal laminated wood-concrete composite floor, the ultimate bearing capacity, the structural rigidity and the stability of the CLT-concrete composite floor can be effectively improved, and the ultimate bearing capacity of the CLT-concrete composite floor can be improved by about 60%.
本发明公开了一种正交胶合木‑混凝土组合楼板，包括混凝土板、CLT板、若干气动排钉及若干木垫块，若干木垫块排布于CLT板的第一表面上，若干气动排钉自木垫块的上表面贯穿木垫块插入CLT板内，气动排钉的插入方向与竖直方向存在夹角，混凝土板浇筑于CLT板的第一表面、木垫块及气动排钉上，通过将气动排钉打入木垫块和CLT板内，能够显著提高混凝土与CLT板的层间剪切能力，提高CLT板各层的层间剪切能力以及CLT板的滚动剪切能力，方便推广扩大正交胶合木‑混凝土组合楼板的适用范围，推动了多高层木结构的发展；同时，本发明提供的正交胶合木‑混凝土组合楼板，能有效提升CLT‑混凝土组合楼板的极限承载能力、结构刚度及稳定性，其极限承载能力可提高60％左右。
