竹木复合正交胶合木(CLT)系列产品是通过把厚度为15-35mm的工程竹材和规格锯材等层板单元迪十燥、分等、表面处理、铺层、淋胶、纵横交错层积和加压胶合等工序而制成的新型大幅面装配式建筑预制型板材，已获中国国家发明专利(ZL201010128681.1)，该系列创新产品具有中国特色，可帮助实现结构和装修的一体化，填补了国内外空白。
竹木复合CLT轻质高强，可充分发挥竹材生长快、强度高和韧性好及木材刚度好的各自优势，表面具有竹材质地，装饰效果好，强度一般比木材CLT至少提高30%以上，可实现原材料的完全国产化，在工厂很容易实现模块化生产，预制成墙板、楼板、屋面板及各类特殊要求的板材，实现各类建筑的现场组装和装配式建造。竹木复合CLT尺寸稳定，也很适合用作各类建筑的内部装修和家具材料，如内隔墙、台面和桌面，它可直接暴露，舒适、亲切、美观，可大大节省装修成本和建筑空间。
与传统钢筋混凝土相比，竹木复合CLT的重量只是前者的20-30%;作墙体材料使用时，一般可比其它空心砖或砌块等常见材料的厚度减小约30%以上，这样对普通民居，房间使用面积一般可增加5-15平方米。
产品特点
采用竹集成材等工程竹和国产橡胶木/杉木或进口SPF等锯材生产的竹木复合CLT预制板和装饰板系列产品，密度约500-700kg/m2。与传统钢筋混凝土、砖结构和轻型木框架结构等建筑系统相比，竹木复合CLT预制板及其建筑系统具有以下优势：
·原材料可实现完全国产化，产品强重比高，承载性能好，尺寸稳定性高，无醛无毒;
·幅面大，运输成本低，施工简单方便，周期短，组装快速安全;
·施工现场噪音低，无污染，无垃圾;表面有竹材质地，可达到免装修的效果，避免了二次装修污染;
·抗震、连接、防火、隔声和保温效果好;
·绿色，低碳，节能，环保，可回用和重复使用。
产品用途
既可做承重结构材，如墙板、楼板和屋面板，又可作装饰材，如内隔墙、台面和桌面，可完全实现结构、装修、保温和隔声的一体化。
The Bamboo-Wood Composite CLT (Composite CLT) are new large-format prefabricated building components made by layering and laminating board units such as 15-35mm thick engineered bamboo and standardized sawn timber, followed by drying, grading, surface treatment, layering, gluing, cross-laminated stacking and pressure bonding. They have been granted a national invention patent of China (ZL201010128681.1). This series of innovative products has Chinese characteristics and can help achieve the integration of structure and decoration, filling the gap in both domestic and international markets.
The composite CLT is lightweight and highly strong. It can fully utilize the respective advantages of bamboo's fast growth, high strength, good toughness, and wood's good rigidity. The surface has the texture of bamboo, providing a good decorative effect. Its strength is generally at least 30% higher than that of wood CLT. It can achieve complete domestic production of raw materials and is easily modularized in the factory. It is pre-made into wall panels, floor slabs, roof panels, and various special required boards, enabling on-site assembly and prefabricated construction of various buildings. The size of the composite CLT is stable and is also suitable for use as interior decoration and furniture materials for various buildings, such as interior partitions, countertops, and tabletops. It can be directly exposed, being comfortable, intimate, and beautiful, which can significantly reduce decoration costs and building space.
Compared with traditional reinforced concrete, the weight of composite CLT is only 20-30% of that of the former. When used as a wall material, its thickness can generally be reduced by about 30% compared to common materials such as hollow bricks or blocks. This can increase the usable area of ordinary residences by 5-15 square meters.
Product features
The bamboo and wood composite CLT prefabricated panels and decorative panels series are produced using engineered bamboo made of bamboo laminated materials, domestic rubberwood/spruce wood or imported SPF sawn timber. The density of these products is approximately 500-700 kg/m2. Compared with traditional reinforced concrete, brick structures and light wood frame structures, the bamboo and wood composite CLT prefabricated panels and their building systems have the following advantages:
·The raw materials can be fully domesticated. The product has a high weight-to-volume ratio, excellent load-bearing performance, high dimensional stability, and is free of formaldehyde and toxic substances.
·Large in size, low in transportation cost, simple and convenient in construction, short in construction period, and quick and safe in assembly;
·The construction site is quiet, pollution-free and there is no waste. The surface is made of bamboo material, which can achieve the effect of no need for decoration, avoiding secondary decoration pollution.
·Good seismic resistance, connection, fire resistance, sound insulation and heat preservation effects;
·Green, low-carbon, energy-saving, environmentally friendly, reusable and recyclable.
Product Usage
It can be used as both load-bearing materials, such as wall panels, floor slabs and roof panels, and as decorative materials, such as interior partitions, countertops and tabletops. It can fully achieve the integration of structure, decoration, insulation and soundproofing.
