[0002] Buildings assembled on site from prefabricated parts are called prefabricated buildings. According to the form of prefabricated components and construction methods, they are divided into five types: block buildings, plate buildings, box buildings, frame plate buildings, and lifting plate and layer buildings. The early prefabricated buildings were relatively rigid and stereotyped. Later, people made improvements in the design, increasing flexibility and diversity, so that prefabricated buildings can not only be built in batches, but also have rich styles.

[0003] After the production of traditional prefabricated columns, they are usually placed at a certain address by a gantry crane. They are usually stored in a stacked manner, that is, wooden wedges are placed on the bottom prefabricated columns, and then the upper prefabricated columns are placed on the wooden wedges. The load-bearing capacity of the wooden wedges is limited. Once damaged, the position of the placed prefabricated columns will tilt, and even adjacent prefabricated columns will collide and rub against each other, causing damage, which is unsafe. In addition, since the required wooden wedges are not specifically produced, the quality is uneven. For this reason, we provide an adjustable pressure-resistant placement device based on prefabricated columns to solve the problems raised in the above-mentioned background technology.
