Firmly connected to demand. This installation is in contrast to the usual sequence already made at this point in time and is expediently done by adding the "connections." be bent over the frame 17.

The frame 17 is turned over with a lifting device 18 and on '"' - the Beam 11 placed on rails 10. A bottom arch covering 19, preferably made of plywood, is placed on the frame 17, preferably Applied with both glue and nails to complete the bottom 17. A floor covering such as linoleum or "A fitted carpet will be laid across the floor 17 at any convenient time during further construction.

In the meantime, the walls are put together at assembly points, which form part of the wall mounting area. This is done a wall mounting frame as shown in Figures 4 and 5 is used. The surfaces 21 are opposite the Vertical inclined and take latches or bolts with a cross section for example 5 x 10 cm (2 4 inches). Colder 22 are arranged on the surfaces 21 ■ that the latches that be connected to each other, take up and in certain positions hold tight. A stop 23 carries the lowermost beam or latch of the wall frame and previously cut latches or bars are placed in the holder 22, as shown in Figure 4, inserted, after which they form the frame 26 together get connected. Each holder 22 consists of a U-shaped Bracket shaped and arranged to cover the edge a beam latch and serves for the fastening work on the spot.

This prevents damage from occurring between neighboring roof elements will. This is particularly important when several residential units are next to each other to form a common many. Meter , long roof. With an on-site construction, such a roof is built on the building itself and its roof panels are aligned along string lines. With the mounting frame according to the invention, however, can be faster and more precisely and the problem of alignment of the rows of shingles or tiling of units with fairly short roof lengths, which are later connected to each other, is solved.

In the final stages of the construction of residential units according to the invention, lifting fittings are attached to each unit to prepare them for transport to the construction site. Long eyebolts 69 are preferably used for the lifting frame, and these bolts 69 extend through openings-in-one. Floor frame 17, as best shown in Figures 9-11. Recesses 70 are preferably made on the underside of the floor frame 17, preferably before it is turned over, let in and take plates 71, which are in the. .Frame 17 and support the heads 72 of the eyebolts 69. The eyebolts 69 preferably extend, as shown, The upper sides of the residential units and the residential units are attached to the eye bolts by cranes or lifting devices canceled.

The trailer 80, which is shown in FIG. 9, is preferably used for the transport of finished residential units to a construction site. The trailer 80 has a hitch 73 at its front end, a front frame 75 which extends rearwardly to wheels 74 in the central portion and

Ί9Α6889

a rear frame 76 connected to the top of the front frame 75 and extending over the wheels 74 and over this extends beyond. The front frame 75 and the rear frame 76 are preferably made of relatively lightweight structural metals.

As best seen in Figure 10, anchor bolts 77 through the side supports 78 of the frame 75 and 76 down in the bottom frame 17 at intervals of 1 m along the frame 75 and 76 screwed to hold the floor frame 17 firmly to the trailer frames 75 and 76. This attachment stiffens and holds the Frames 75 and 76, which are braced by the strong and rigid construction of the floor frame 17 ·. Through this stiffening For example, the trailer 80 can be lightweight yet strong enough to support heavy living units. This brings the The advantage that only a few wheels 74 directly next to one another in the central section of the trailer 80 are required and a relatively long length of the trailer of housing units can cantilever behind the wheels 74. The total height of the bela- ·. which trailer is relatively low and the total weight of the trailer 80 and its housing units is relatively small and meets the requirements of the legislature and the motorways for vehicles.

The known trailers for pulling heavy objects must always be strong enough to carry the cargo alone. A Such a trailer, if it were to be used to transport residential units according to the invention, would have to be a low-loader be with a massive platform carried between the tow bar and a rear axle with many wheels would have to. Only one residential unit at a time could be transported with it will. In a trailer according to the invention is the
