Description

Tree house community structure

Technical Field

The utility model relates to a house construction field especially relates to tree house community structure.

Background

Due to the improvement of environmental awareness and the trend towards green and rural life in recent years, in some existing gardens, greenbelts, parks or farmhouse funs, in order to achieve the purposes of saving cultivated land resources, avoiding ground hardening, beautifying the environment, protecting the ecology and the like, a plurality of tree houses built by utilizing naturally growing plants are provided, the tree houses can be built without occupying construction land and hardening the land, and the tree houses are suspended in the air and full of the wild interest. For the construction of a tree house, a structural support piece made of steel or other materials is often erected on a trunk of a big tree to serve as a house framework, or the big tree is used as a support column to build an upper-layer building to form a pavilion, a corridor platform and the like. Although the small arbor has better ornamental value, the height of the tree is between 5 and 9 meters, the height of the main rod with higher strength is only 1 to 5 meters, and the support cannot be formed for building a higher building structure, the upper structure of the building such as a ceiling supported by the small arbor has low height and low floor height, so that people feel oppressed in the upper structure, the ecological building is greatly limited by the small arbor, and in the prior art, the small arbor cannot be well combined with the building structure.

The crape myrtle tree is a small tree, is called a thousand-year old tree, has strong vitality, bright color and long flowering phase, is an ornamental tree commonly planted in gardens, greenbelts, parks and farmyard funs, and is mostly used for ornamental purposes and cannot be combined with building construction due to the limitation of the tree height of the naturally-grown crape myrtle tree in modeling and utilization of the crape myrtle tree.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a tree house community structure fully makes the crape myrtle tree as little arbor combine with building structure, and the structure is firm, need not to build house skeleton in addition, and the sight is high, and the practicality is strong.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model discloses a tree house community structure, which comprises a corridor platform and a tree house,

the tree house comprises a crape myrtle tree planted on the land, a plurality of branches growing on a main rod of the crape myrtle tree are mutually crossed and woven to form a cage-shaped framework structure, the branches used for weaving the framework structure are gathered at the top of the framework structure and are mutually crossed and woven to form a connecting column, the branches used for weaving the connecting column form a top crown at the top of the connecting column, the interior of the framework structure is used for people to live in, and an inlet and an outlet for people to come in and go out are formed in the framework structure;
