The invention relates to the construction, in particular to installation, can be used in the construction of a folded cover by the method of lifting and is an improvement of the invention according to the author. St. No. 1425296,

The purpose of the invention is to provide the possibility of mounting long-span folded coverings.

Fig. 1 shows a folded cover before it is lifted; a plan, a general view in Fig. 2 — node I in Fig. 1; in Fig. 3, section A-A in Fig. 2 before raising the cover j in Fig. 4 - then after lifting and grouting seams; Fig. 3 shows a section B-B in Fig. 2, before the rise of the coating; in Fig. 6, the same, after lifting and grilling the seams.

The method of erecting a folded coating is carried out as follows.

After making a folded cover at ground level in the form of a single plate 1 and the simultaneous formation or formation from plate 1 of triangular elements 2 along all matching sides (both over long 3 and short 4), L-shaped beams 5 are installed with the shelf up they are hinged between themselves by transverse reinforcement bonds 6, moreover, in the center of the slab and in the places of coupling, holes are made into which the lifting means are installed. In this case, the rise of the coating is carried out ahead of the central belt, and the fixation is accomplished by monolithing the seams between the triangular elements of the coating.

The triangular elements of the coating are formed as follows. Contour

each triangular element 2 set the L-shaped beams 5 shelf up. The l-shaped beams 5 of each element 2 in the corners are rigidly interconnected, and adjacent along their long sides are articulated by means of the armature 6 lower. Adjacent beams 5 on short sides are hinged by armature

6 above, and if necessary - and lower. After that, lifting to the design position is performed, followed by installation of the longitudinal reinforcement.

7 and filling of the seams formed in the interval between the paired L-shaped beams 5.

The proposed method of erecting a folded cover allows a significant increase in the spans, since instead of a flat slab they form a ribbed structure, the edges of which are significant} 1 o higher than the height of the slab.
