The invention relates to an installation device for frame structures of buildings, in particular boiler buildings, comprising a crane device having a substantially vertical frame and a substantially horizontal boom part, said boom part being adapted to rotate around said frame.

The installation of the frame structures of buildings, such as boiler buildings, is currently carried out as follows. The crane lifts a work basket to the side of the building pillar, which the installer attaches to the pillar. The installer performs the installation and power connections of the horizontal and diagonal bars from the work basket. However, the working basket often remains at an unfavorable height, and when fixing the frame structures, the working basket attached to the side of the column has to be moved around the column to different sides in order to carry out all the necessary installation work. Such rotation of the working basket around the column naturally takes a very long time and requires its own crane with which the support of the working basket and the necessary movements can be performed. As a result, a separate crane is needed to lift the steel blocks of the frame structures. The current method of installation therefore requires two cranes, which are often in the way of each other, which further slows down the installation work. In addition, it is difficult to get electricity, gas and compressed air into the 2,56815 work basket. The installer's working position in the work basket is unfavorable and thus tiring and slows down work. With regard to the state of the art, reference is also made to, for example, Danish Patent Publication No. 70334.

In addition, the current installation method is poor in terms of occupational safety, as after the horizontal beams have been attached to some extent, the installer has to install the remaining structures on top of the horizontal beams, often faltering while working on the horizontal beam and falling to the ground. The installer can, of course, improve his occupational safety to some extent by fastening himself with a safety belt when working on a horizontal beam, but this way of working is not effective.

In summary, the previously used installation method can be said to be tiring for the installer, dangerous for occupational safety and poor in terms of work quality. In addition, the installation work is slow, which makes the installation costs very expensive.

The object of the invention is to provide an installation device which enables the installation of the frame structures of buildings in a meaningful and efficient manner. It is also an object of the invention to provide an installation device by means of which the highest possible occupational safety is achieved. Yet another object of the invention is to provide an installation device with which installation costs can be substantially reduced. Other objects and advantages of the invention will be apparent from the description of the invention.

The objects of the invention are achieved by an installation device, which is mainly characterized in that a plurality of boom structures are attached to the crane body, supporting the work basket at one end, and said boom structures being adapted to rotate horizontally around the crane body 180 ° or less, all installation sectors in the building are within reach of mobile work baskets. Other important features of the invention are set out in claims 2-8.

Numerous advantages are achieved with the installation device according to the invention. The working baskets of the mounting device can be rotated horizontally and also moved up and down, making it easy to reach each mounting location. Occupational safety is as high as possible, as all installation work can be carried out from the work basket. The installation work is made as fast as possible, which means great savings in installation costs.

The invention will be explained in detail with reference to the basic solution of the invention shown in the figure of the accompanying drawing, to which, however, the invention is not intended to be exclusively limited.

In the figure, reference numeral 10 generally denotes a crane device comprising a vertical body 11 and a horizontal boom part 12 arranged to rotate around the body 11. In addition, the crane device 10 comprises a crane driver's booth 13. The crane device 10 is thus a conventional crane device used on a construction site. When the new installation method according to the invention is applied to boiler buildings, for example, the crane device 10 is placed in the middle of the boiler building, whereby the crane device 10 can perform all lifting operations from the ground to the construction site.

According to the basic idea of the invention, a plurality of boom structures 16 are arranged to rotate around the body 11 of the crane device 10, and the boom structures 16 support working baskets 15 at one end, which preferably have four pieces. In this embodiment, the boom structures 16 are attached to a common frame body 14. The boom structures 16 are further adapted to move in an up-down direction, whereby the working baskets 15 can always be aligned with the desired object. The magnitude of the rotational movement of the boom structures 16 around the body 11 of the crane device 10 depends on the number of working baskets 15. However, it is preferred that the boom structures 16 are adapted to rotate horizontally 180 °, although e.g. e.g. when using four working baskets the 90 ° horizontal rotation angle of the boom structures 16 is sufficient, whereby the working baskets 15 make it possible to reach each workpiece 15 their own installation sector.

The installation device according to the invention preferably further comprises a body 17 arranged slightly below the boom part 12 of the tower crane 10, to which a boom structure 19 is attached, which at one end supports a work guide box 18. The boom structure 19 is adapted to rotate horizontally preferably 360 °. the work of the work basket 15 and the installers therein. The frame structure of the boiler building is generally indicated in the figure by reference numeral 20.

The Tower Crane 10 erected in the middle of a boiler house or other building in the usual way is preferably a so-called self-growing type, because as the height of the boiler building increases, as the installation work progresses, an ever-higher lifting height is required. The work baskets 15 are equipped with the necessary accessories,
