Description

Orthogonal nailing bamboo board

Technical Field

The utility model relates to a bamboo timber board formula component belongs to the building structure field among the civil engineering, in particular to simple and easy assembling formula bamboo plank formula component suitable for building of our country bamboo timber structure.

Background

The existing large-sized panel type wood member is mainly an orthogonal laminated wood (CLT) board, and the CLT is a laminated wood product formed by mutually orthogonally laminating and assembling a plurality of layers of wood boards and integrally gluing the laminated wood boards by adopting an adhesive. The CLT plate has the excellent performances of high rigidity, high bearing capacity, good fireproof performance, capability of being bent in two directions and the like. In modern wood-structure buildings, CLT boards can be used as floor panels and shear walls in general. In addition, because the CLT has a large breadth size, the plate type components are all prefabricated in factories and assembled in situ, and therefore, the CLT has extremely high construction efficiency. At present, the CLT plate is an important stressed component of a multi-high-rise wood structure building. However, the CLT has a large amount of adhesive, which has negative effects on the environmental protection of the components and the indoor air quality, and the gluing processing has high requirements on equipment, so that the CLT is only produced and manufactured in specialized factories, has high cost and has high requirements on transportation conditions. In addition, the CLT adopts needle-leaved sawn timber with high grade as a basic material, but is limited by the practical situation that structural timber resources in China are deficient, and at present, the timber adopted for producing the CLT is mainly imported structural timber, so that the cost of the CLT is further increased.

Plywood nailed timber (NLT) is another commonly used panel member in wood construction. NLT is a plate member formed by overlapping wooden laths along a wide surface, nailing the wooden laths along the wide surface according to a certain distance distribution and overlapping the wooden laths layer by layer. NLT production is simple, and through the concatenation shaping, mutual overlap joint between the adjacent batten makes the board-like component of great breadth and span with small-size batten, and the material utilization efficiency is high. Because the processing technology does not need to depend on large-scale equipment and adhesive, the production efficiency is high, the cost is lower, and the processing technology can be manufactured and assembled on site. However, the wood lath in the NLT board can only be used as a one-way board because the wood lath has a limited length and the butt joint exists in the actual NLT board, which has a significant negative effect on the bending resistance of the NLT board, and the wood lath in the NLT board is arranged in a single direction, which significantly limits the application range of the NLT board. In addition, the main material of the NLT component in China is imported needle-blade sawn timber at present, and the resource bottleneck problem exists.

Therefore, a new bamboo wood plate type component is provided, and the practical requirement for promoting the development of modern bamboo wood structure buildings is met.
