Description
Technical Field
The invention relates to the field of building exterior walls, in particular to a heat-insulation prefabricated building exterior wall structure.
Background
Buildings assembled from prefabricated parts at the site are called fabricated buildings. The building block is divided into five types, namely a block building, a plate building, a box building, a framework plate building, a rising-rise building and the like according to the form and the construction method of the prefabricated part.
With the development of modern industrial technology, building houses can be manufactured in batches and sets like machine production. The prefabricated house components are transported to a construction site to be assembled.
Fabricated buildings have become of interest since the beginning of the 20 th century and have been realized through the sixties. The first attempts made in English, French, Soviet Union, etc. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world.
Early fabricated buildings were rather rigid and uniform in appearance. Later improvements in design have resulted in increased flexibility and versatility to allow modular construction not only in batch, but also in a wide variety of styles. The movable dwelling house is an advanced assembly type building in America, each dwelling unit is like a large trailer, and the movable dwelling house can be used only by pulling the movable dwelling house to the site by a special automobile and then hoisting the movable dwelling house to a floor cushion block by a crane to be connected with a pre-buried water channel, a power supply and a telephone system. The movable dwelling house is internally provided with facilities such as a heating system, a bathroom, a kitchen, a dining room, a bedroom and the like. The movable dwellings can be formed into a unit independently or can be connected with each other.
A large number of building parts are produced and processed by workshops, and the types of components mainly comprise: external wall panel, interior wallboard, superimposed sheet, balcony, air conditioner board, stair, precast beam, precast column etc..
The existing external wall panel is mainly manufactured in a pouring mode, and is heavy in weight and complex in manufacturing process.
