[0002] Fabricated building is a modern building method, which is formed by transporting the parts or all components of the building to the construction site after processing in the factory, and then connecting and assembling through reliable connection. This building method has the characteristics of design standardization, component factory production, construction assembly, and management informatization. Building components (such as floor slabs, wallboards, staircases, balconies, etc.) are mass-produced in the factory using molds to ensure the quality and precision of the components. Factory production reduces wet work on the construction site, improves construction efficiency, and shortens the construction period.

[0003] With the rapid development of the construction industry, fabricated buildings are widely used due to their fast construction speed, less dependence on weather conditions, labor saving, and improved building quality. However, during the installation of fabricated wallboards, the wallboard is often lifted by a crane and then hoisted directly above the installation location. During hoisting, the wallboard is prone to deviation, requiring multiple re-measurements and adjustments. When the wallboard is moved down to connect with the base plate, multiple people are needed to manually adjust the position of the wallboard. The installation process relies on workers' experience, and the standardization of construction is low. There are problems such as positioning difficulty, installation inconvenience, low efficiency, and large errors. Therefore, how to ensure that the wallboard can be accurately and quickly positioned at the predetermined location has become a key factor restricting the construction efficiency of fabricated buildings.

The design solves the problems of the existing wallboard hoisting process, such as easy deviation, the need for multiple re-measurement and adjustment, the need for multiple people to manually adjust the position of the wallboard when the wallboard is moved down to be connected with the base plate, the dependence on the experience of workers in the installation process, the low standardization of construction, the positioning difficulty, the installation inconvenience and the like, and the problems of low efficiency and large error.

[0028] The hollow square steel 4 and the wallboard guiding assembly 5 are matched and can be used with a crane at the same time, the rapid guiding and positioning of the prefabricated wallboard is realized, the rapid installation of the prefabricated wallboard is assisted, the installation time is greatly shortened, and the construction efficiency and accuracy are improved.

[0029] In the embodiment, the wallboard guiding assembly 5 includes a wallboard hanging plate 51, a connecting rod 52, a limiting baffle 56 and a guiding roller 57, the wallboard hanging plate 51 is provided in a U-shaped structure and has two groups, the lengths of the two sides of the wallboard hanging plate 51 are different, the two groups of wallboard hanging plates 51 are fixedly connected through a plurality of connecting rods 52, a plurality of pairs of guiding rollers 57 are uniformly installed on the left side of the long side of the wallboard hanging plate 51 at the lower half segment position, the tangent line at the edge of the guiding roller 57 is located outside the side of the wallboard hanging plate 51, the limiting baffle 56 is fixedly arranged on the wallboard hanging plate 51 opposite to the guiding roller 57, and the width of the limiting baffle 56 is greater than the width of the wallboard hanging plate 51.

When the wallboard hanging plate 51 falls to the lowermost position on the guide sliding groove 10, the direction rotating screw rod 54 is rotated to unlock the wallboard guiding assembly 5, so that the wallboard is separated from the wallboard guiding assembly 5. Then continue to control the wallboard to fall through the crane until the wallboard is completely installed.
