The adhesive ability of bamboo scrimber is critical for its use in large‐scale engineering structures. Cold‐pressed bamboo scrimber with varying sanding mesh and density was made and then bonded with polyurethane resin. The adhesive was concentrated on the surface, assisting the anchoring into the material surface. The shear strength and immersion peel strength are studied as parameters to determine the glue qualities. The optimum gluing characteristics were obtained using a 120 grit sandpaper and a density of 1.15 g/cm3. The results indicated that at a density of 1.15 g/cm3, the gluing characteristics rose initially and subsequently dropped as the number of sanding meshes increased. The bonding strength improved with increasing density when 120‐mesh sanding was used. With increasing density, the bamboo fiber distribution inside the material got more compact, while the resin dispersion became more uniform. Thus, the surface porosity and roughness were decreased.

“…The large-sized bamboo scrimber is mostly created at this step by finger joint, pin, or adhesive. [7,8] The finer joints and pins cause splitting on the surface of the bamboo scrimber, resulting in a significant loss of strength. [9,10] As a result, the glue connection was an excellent decision.…”

“…According to Ceylan and Girginannular [ 33 ], threads make fasteners easy to insert and hard to pull-out. Rezvani et al [ 34 ] showed that fully threaded screws in angle bracket connections outperformed partially threaded screws in terms of uplift, in-plane shear, and out-of-plane stress. D’Arenzo et al found that adding inclined fully threaded screws in the bottom corner of traditional angle brackets significantly increased the performance for tensile loading, avoiding the usual low withdrawal resistance of the annular-ringed nails in the bottom plate [ 35 ].…”

Withdrawal Performance of Nails and Screws in Cross-Laminated Timber (CLT) Made of Poplar (Populus alba) and Fir (Abies alba)

Cross-laminated timber (CLT) can be used as an element in various parts of timber structures, such as bridges. Fast-growing hardwood species, like poplar, are useful in regions where there is a lack of wood resources. In this study, the withdrawal resistance of nine types of conventional fasteners (stainless-steel nails, concrete nails and screws, drywall screws, three types of partially and fully threaded wood screws, and two types of lag screws), with three loading directions (parallel to the grain, perpendicular to the surface, and tangential), and two layer arrangements (0-90-0° and 0-45-0°) in 3-ply CLTs made of poplar as a fast-growing species and fir as a common species in manufacturing of CLT was investigated. Lag screws (10 mm) displayed the highest withdrawal resistance (145.77 N), whereas steel nails had the lowest (13.13 N), according to the main effect analysis. Furthermore, fasteners loaded perpendicular to the grain (perpendicular to the surface and tangential) had higher withdrawal resistance than those loaded parallel to the grain (edge). In terms of the layer arrangement, fasteners in CLTs manufactured from poplar wood (0-45-0°) had the greatest withdrawal resistance, followed by CLTs manufactured from poplar wood in the (0-90-0°) arrangement, and finally, those made from fir wood in the (0-90-0°) arrangement. The fastener type had the most significant impact on the withdrawal resistance, so changing the fastener type from nails to screws increased it by about 5–11 times, which is consistent with other studies. The results showed that poplar, a fast-growth species, is a proper wood for manufacturing CLTs in terms of fastener withdrawal performance.
