The fabricated building is a building fabricated by assembling prefabricated components on a construction site, and 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 construction method of the prefabricated components.
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 building, each dwelling unit is like a large trailer, and the large trailer is pulled to the site by a special vehicle, then is hoisted to a floor cushion block by a crane and is pre-buried with water
The telephone can be used by connecting the telephone line, the power supply and the 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.
When an inner wall decoration plate is installed in an existing fabricated building, a prefabricated plate is usually manufactured in advance and then transported to an assembly site for assembly, and in the installation process of the prefabricated plate, the prefabricated plate needs to be erected, adjusted to a corresponding height, aligned with the installation position on a wall body, and then spliced and installed by means of an auxiliary tool.
The invention discloses an inner wall decorative plate fixing device of an assembly type building with the patent number of CN201911310446.3, which comprises a moving seat, wherein a Lyte gas rod is arranged on the top surface of the moving seat, a rotating seat is welded at the end part of a piston rod of the Lyte gas rod, an adjusting component is arranged in the rotating seat, a clamping component is arranged at the front end of the adjusting component, a power component is arranged at the rear end of the rotating seat, an inner wall decorative plate to be installed is clamped and fixed by the clamping component, the adjusting component is driven by the power component to rotate on a horizontal axis, the horizontally arranged clamping component rotates to a vertical state, and then the adjusting component is driven by the power component to rotate on a vertical axis, so that the clamping component drives the inner wall decorative plate to correct the installation position, and the inner wall decorative plate is conveniently connected and fixed with the inner wall.
However, in the above patent, only one clamping assembly is provided, and after one decorative plate is fixed each time, the decorative plate needs to be returned to the horizontal position after installation is finished, so that the next decorative plate can be fixed again, and the use is inconvenient.
Based on the above, the invention designs an inner wall decorative plate fixing device of a fabricated building to solve the problems.
