Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a device for transporting and placing prefabricated building components applicable to narrow spaces. Background Art

[0002] In the specific construction process of an entire building, generally, the main part of the entire building is first constructed, and then components such as building blocks are used to isolate the spaces on each floor of the building. There are certain gaps between these block walls and concrete walls. Even if there is a process of hanging a mesh, gaps will still appear between these concrete walls and block walls, resulting in the generation of gaps in the subsequent wall surfaces. At the same time, during the masonry installation process of the entire door frame or window frame, if building blocks are used, their strength is generally relatively poor. Therefore, generally, for places where walls such as door frames require higher strength, secondary prefabricated components are needed. Although the change in gaps cannot be directly eliminated, the strength of the entire window area can be further improved.

[0003] During the transportation and placement process of these secondary prefabricated components, since the construction of the main part of the previous building has been completed, a relatively narrow handling environment is provided for these secondary prefabricated components. At the same time, most secondary prefabricated components are large in volume and heavy in weight, and the elevation needs to be repeatedly calibrated when installing embedded parts. The repeated adjustment of the position of the secondary prefabricated components increases the labor intensity, and the installation quality of the secondary prefabricated components will directly affect the quality of individual processes and the construction quality of subsequent processes.

[0004] When installing secondary prefabricated components, the traditional method is to process the embedded parts in the factory according to the design drawings and then install them by means of manual labor and on-site scaffolding assistance. The construction efficiency is quite low and the installation speed is slow. In addition, due to the influence of human factors, there will be deviations every time the elevation position is manually adjusted and repeated adjustments are made. This not only increases the difficulty of installing secondary prefabricated components and requires repeated correction of the spatial position of the secondary prefabricated components, but also directly affects the height of other masonry walls, and the construction quality of the final embedded parts cannot be guaranteed.

[0005] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention
