Description

A quick-installed bamboo house

technical field

The utility model relates to a building, in particular to a quick-installed bamboo house which is convenient for assembly and disassembly.

Background technique

The existing mobile houses and light houses are mainly steel structures, masonry structures or reinforced concrete structures, which consume a lot of steel and cement, and the metallurgy and cement industries have always been high energy consumption and high pollution industries. The production of steel and cement It needs to consume a lot of energy and non-renewable natural resources, and at the same time generate a lot of waste water, waste gas and waste residue, which seriously affects the ecological environment and does not meet the requirements of sustainable development; Difficulty, long construction period and other shortcomings. Therefore, more and more people advocate the use of natural, environmentally friendly, and renewable organic materials, which are processed by modern techniques and made into structural components, gradually replacing steel and cement components, and believe that it is the only way to achieve sustainable development in the construction industry. Make it gradually become an important opportunity to ensure the sustainable development of human society. Currently, the most used natural, renewable organic material in construction is wood.

There are two main types of wood used in construction. One category is logs and wood squares and boards made of logs after sawing and planing. The use of logs and their products to build wooden structures has a long history in our country. The wooden structure has the advantages of convenient processing, simple construction, elegant appearance and good applicability. However, in our country, due to the lack of forest resources, the state strictly controls the felling of timber. Even for artificial afforestation, due to the long maturity period of forest trees and extremely limited sources of logs, it is impossible to build a large number of wooden structures. The other type is glued wood, which is generally a board, using adhesives and pressure forming processes to combine smaller boards into relatively larger boards. Glued wood can generally only be used for interior decoration or as a formwork.
