Strengthening Method of Joint Points for Fast-growing Wood Chair Furniture
In order to alleviate the shortage of high-quality wood resources,expand the utilization ways and improve the utilization value of fast growing wood,a joint strengthening method combined fast growing poplar and beech as a joint of two components was put forward.The pull-out and flexural properties of the joint-reinforced poplar T specimen,the all-beech T specimen and all-poplar T specimen were tested respectively.The results showed that the pull-out strength of T-shaped poplar specimens with reinforced sturcture is increased by 1 999.56 N(47.71％)compared with that of all T-shaped poplar specimens.It is only 175.8 N and 2.76％lower than the whole Beech T-type specimen.The bending strength of T-shaped poplar specimens with contact reinforcement is 487.85 N(93.07％)higher than that of all T-shaped poplar specimens.Compared with all Beech T-type specimens,the increase was 143.84 N,an increase of 16.56％.It is proved that the joint structure made by the reinforced method is suitable for fast-growing poplar chair furniture.
