10.2.1 Criteria for Building Industry
In construction industry the most important part of building is joints. There is different
type of joins and connection of bamboo poles. The Double Butt Bent Joint, two
bamboo poles were used. The first is horizontal, the second is vertical.
The Friction–Tight Rope connection is the most common way to connect bamboo.
Originally used natural materials, such as bast, strips of bamboo, rattan/hemp and
palm fibre from coconut/sago, are used as a rope for connecting bamboo poles. At
present, iron wire and plastic straps/ropes are also used for connection with friction (Janssen 2000). The Friction—Tight Rope connection technique can be used
in almost all circumstances that may appear during the construction of a building
and reduces the likelihood of a bamboo fracture. It is easier to compact because it is
possible to apply epoxy or other materials as a coating. However, the choice of rope
material can affect the construction, so you need to check the rope for damage from
moisture, putrefaction and provide protection from insects (Janssen 2000).
Taking advantage of a secondary interlocking element, this type of connection
is widely used in context with rope connections. The bolts have to transfer tractive
and compressive forces. In addition, this can be seen in garden fences and furniture
(Socrates 2012). This type of connection is used with a blocking element that can be
made of wood and bamboo, and a cannon joint is used. This type of connection is
most often seen in garden fences and furniture. To begin with, drill the vertical and
horizontal bamboo beams; the vertical that is connected to the wooden cipher should
have holes larger than the horizontal pole. The used pin (made of wood or bamboo)
connects two bamboo poles, and then a bamboo wedge is fixed to strengthen the
connection. After that, you need to cut off the protruding parts of the curtain and
make the surface of the plug smooth. To strengthen the bond use an adhesive or a
rope (Socrates 2012).
Positive Fitting connection creates a beautiful view of the bamboo in the design.
The connection can be combined with other connections, such as plug-in technology,
attachment technique. A big plus of compound is that you can reduce the cost of
bamboo pillars. In addition, when small gaps are detected on the surface, the assembly
can be easily sealed and fixed (Janssen 2000).
However, it is necessary to consider the connection of two bamboos, when
constructing a construction, the diameters of bamboos should be different. In addition, when creating a hole on the bamboo poles, the work of experienced masters
is important, as if not working correctly, the strength may decrease and may cause
cracking and splitting (Regenerative Design Institute’s Photostream 2007).
Special construction design is used in constructing. One of the type of bamboo
connection is based on plug—in joint and friction tight rope joint (Schröder 2009). A
special and durable design, very unique and easy to build. An effective and easy way
of connecting does not require high skills of working with bamboo. This “sandwich”
design does not require a structural frame and does not request special tools, only
the bolt and nuts. The posts are connected to each other, three bamboos are used,
four postures of bamboo are added from the top in the middle, five are used at the
