ANCESTRAL BAMBOO

“A man can sit in a bamboo house under a bamboo roof, on a bamboo chair at a bamboo table, with a bamboo hat on his head and bamboo sandals on his feet. He can, at the same time, hold in one’s hands a bamboo bowl, on the other hand bamboo chopsticks, and eat bamboo shoots. When he finishes his meal, which is cooked over a bamboo fire, the table can be washed with a bamboo fabric, and he can shake himself with a bamboo fan, take a nap on a bamboo bed, lying on a mat of bamboo, with his head resting on a bamboo pillow. Your child can rest in a bamboo crib, playing with a bamboo toy. When he got up he would smoke a bamboo pipe and, with a bamboo pen, write on bamboo paper, or carry his things in a bamboo basket suspended by a bamboo stick, with a bamboo umbrella over his head. He can then walk on a suspended bamboo bridge, drink water from a bamboo shell, and scratch it with a bamboo scraper.”

Bamboo is an ancestral material that walks with humanity. Used as raw material base in several Asian countries and some Latin American countries like Colombia and Costa Rica, its democratic use is guaranteed by the abundance with which it is in the environment and by having such diverse uses and a so rapid renewal. In many countries, it is known by names that refer to the abundance of material, as in India, which is called “wood of the poor” or in China, which uses the term “friend of the people.”

“Historically bamboo has accompanied the human being, providing food, shelter, tools, utensils and a myriad of other articles, and is currently estimated to contribute to the subsistence of over one billion people. , has been the development of industrial uses of bamboo. ”

(Sastry, 1999)

Today it has been popularizing by the increasing stimulus to renewable constructive technologies, looking for the reduction of the extraction of materials with very long renewal time as is the case of wood, which is often done in an illegal and predatory way, causing the destruction of native forests such as the Amazon Rainforest itself that in less than 50 years had almost 20% of its forest cover destroyed.

“For decades, to meet the demand for roof timber structures, the main lumber centers located in the South and Southeast Regions provided the paraná pine and the pink peroba, which were exploited in the native forests of these With the exhaustion of these forests, the supply of native timber began to be carried out, in part, by bordering countries, such as Paraguay, but more significantly, by the Amazon Region ”

Bamboo is a grass that usually develops in tropical climate and has an extremely fast and cyclic growth. Some species grow up to one meter a day until they reach adulthood, allowing an annual harvest without any structural modification in the bamboo forest (either overwhelming or intubated). In the present work the results obtained in the analysis of the results obtained in the analysis of the obtained results, musical instruments, etc. are analyzed.

By its constituent way, it behaves like a water storage pump whose operation is given by its communicating vessels. It absorbs important volumes of water that are housed both in its rhizomatic system and in its stem. Thus, it contributes to the enrichment of soils, provides biodiversity and regulates water resources.

The choice of cutting edges must respect some rules so that the maturation of the material is complete, ensuring that all its mechanical properties work well. There are different ripening times for different uses.

THE TREATMENT

Bamboo presents problems of durability when not treated because it has a significant amount of starch, attracting fungi and insects that hinder the resistance of the material. The treatment process reverses the “taste” of bamboo, reducing the amount of starch that makes it more interesting for insects.

Treatment processes are subdivided into traditional and chemical processes, depending on the local availability of resources. Some possible traditional methods are healing by maturation in the forest, immersion in salt water, fire action or even by smoke. As a positive point, they are extremely inexpensive methods or at no cost, functioning well within the local logic in which the office is inserted seeks to work with those local and natural processes whenever possible, in cases where this is not possible used is made by the mixture of salts as boric acid with borax.

TRANSFORMATION AND ADAPTABILITY

It is estimated that in China (the country that uses the most bamboo in the world) there are more than 4 thousand ways of using the material. These forms are so diverse that it would be impossible to date all of them at one time, so focus on the use of bamboo in civil construction, which appears as an element from the structural aspect of the work to closures, floors and decks. It is a material that adapts to different modes of transformation, being able to be ripped, framed or even used in its original tubular form.

We can illustrate some technical variations with images of works already done by the office, allowing the understanding of how these different modes of material transformation are important for the composition of an architecture predominantly made in bamboo.

HUMO RESTAURANT

The Humo restaurant (concluded in 2017 in Mexico) is almost all constituted by the material. Double threaded bamboo pillars are connected to the concrete foundation by metal waits and hold the ripated bamboo beam compressed by clamps – new technique that allows the beam to maintain the mechanical characteristics of the bamboo (tensile, bending and torsion resistance, at the same time being flexible) – serving as a basis for structured coverage by bamboo cabinets covered by lining (made by the technique of mats covered by bamboo tile).

TREEHOUSE

The House on the Tree (completed in 2015 in Colombia) is accessed by a ramp that is structured by ripped and compressed bamboo arches, these anchored in the concrete foundation. Threaded bamboo axially arranged to the tree also contribute to the structure of the ramp and the building, which has all its bamboo enclosures, whether in raster or ripados panels.
