Treehouse Attachment Bolt
Treehouse attachment bolts or TABs are specialized bolts engineered for tree house, treehouse construction.Globe Pequot, "Knack Treehouses: A Step-by-Step Guide to Designing and Building a Safe and Sound Structure", 2010, p. 66/ref> Various models and trademarks exist, with names such as Garnier limbs (GLs); tree anchor bolts; artificial limbs; heavy limbs or hyper limbs (HLs); special tree fastener or stud tree fastener (STFs). They may be either of through fastener style (for smaller trees) or side mount type for larger ones. Description One of the main features of TABs is their strength, requiring fewer tree penetrations for robust fastening of a treehouse and hence less damage to a live tree. A typical TAB consists of a threaded metal bolt and a larger diameter collar. The latter provides an extra bending strength by bearing upon the compression strength of the tree grain. Since treehouses are subject to frequent load reversal produced by winds, TABs must be made of spring s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

A tree house, tree fort or treeshed, is a platform or building constructed around, next to or among the Trunk (botany), trunk or branches of one or more mature trees while above ground level. Tree houses can be used for recreation, work space, habitation, a hangout space and observation. People occasionally connect ladders or staircases to get up to the platforms. History Prehistoric hypotheses All great apes build tree platforms or nests as shelter from dangers on the ground, and the habit may have been inherited by humans. While no evidence of prehistoric human-made tree houses has been found, wooden structures would not have survived over time. In contrast, evidence of cave dwellings, rock shelters, and bonfires is detectable, but is notably scarce from before 40,000 years ago. This has led to the speculative hypothesis that archaic humans may have lived in trees until then.
