The invention relates to the construction of predominantly inventory structures.

The aim of the invention is to reduce the laboriousness of making a canopy, increase compactness in the folded position and reliability of folding.

FIG. 1 shows a collapsible canopy in the process of folding (or unfolding) a fence, a general view; in fig. 2 - the same, after folding the fence, before folding the columns (or before unfolding the fence); in fig. 3 - the same, in the folded position; in fig. 4 - node adjoining the fence to the odd bolt in the working position; in fig. 5 - the same, to the even bolt in the working position; in fig. 6 - knot of near stringing of the column to an odd bolt; in fig. 7 - leg of an even bolt on braces; in fig. 8 - node of the junction of the lower rod and diagonal strut in the column; in fig. 9 - unit for connecting the lower rods along each other; in fig. 10 - node adjoining the fence to the black bolt in the folded position; in fig. 11 - run, view from its end; in fig. 12 - an adjoining unit of a guard to an odd bolt in the folded position.

The collapsible canopy includes bolts 1 and 2, respectively, odd and even from the edge of the structure, connected by hinges 3 and 4 with girders 5, on which the corrugated fences 6 are attached with edges protruding upward

horizontal distance from its vertical axis and vertically from the lower flange of the girder, and the girder is below and even at a height of at least half the width of the lower flange of the even girder and is displaced horizontally from the hinge connecting the even girder with the girder , at a distance not less than the vertical distance between this hinge and the bottom of the even girth.

3. A curtain in accordance with claim 1, characterized in that the lower rods are pairwise articulated in pairs with each other with the possibility of being shifted down when folded.

4. A hangout according to claim 1, characterized in that, in order to increase the reliability of the folding, the protruding down of the springs attached to the even beams are made in height equal to the height of the corrugated fencing and mounted with the possibility of contacting the spikes with the protruding upward edges of the corrugated fencing.

under the slings 7 and 8, made with edges protruding downward and attached respectively to bars 1 and 2. Crossbars 1 are connected by hinges 9 to columns 10, connected by hinges 11 to the lower ends of braces 12 and to lower rods 13. Crossbars 2 equipped with supporting elements 14, contacting and self-centering with the upper ends of the struts 12 in the working position of the folding frame and the hinges 15 pairwise connected to each other. The braces 12 and the purlins 5 are located relative to each other in different vertical planes. Horizontal cross size

the supporting element 14 may not exceed twice the height of the girder 5, the horizontal transverse dimension of the lug 7 of the odd girder 1 may be equal to double the height of the corrugation of the corrugated fencing 6, the horizontal transverse dimension of the lath 8 of the even girder 2 may be equal to double the sum of the girder 5 and the height of the corrugated fencing 6 with the arrangement of the edge of the latch 8 even bolt 2 horizontally from the hinge 4

5 connecting another girder 5 with an even bolt 2 at a distance equal to the vertical distance from this hinge 4 to the upper corrugation of the corrugated fence 6, joint 3, connecting girder 5 with an odd bolt 1, can be located on the same the horizontal distance from the vertical axis of the odd bolt 1 and vertically

ticking from the top of the corrugation of the corrugated fence 6, the hinge 4 connecting the girder 5 to the even bolt 1 is located at the same distance from horizontally from its vertical axis and vertically from the lower flange of the girder. Run 5 can have a notch 16 of height d at least half the width of the lower flange of even even bolt 2 on the side of an even crossbar 2 and be mixed horizontally from the hinge 4, connecting even an even bolt 2 with a distance of f not less than the vertical distance nor g between this hinge 4 and the bottom of the even girder 2. In addition, the rods of the lower belt 13 can be connected in pairs with each other by the hinges 17 with the possibility of mixing downwards when folded. The protrusion, willow down of the edges of the strips 8 attached to the even crossbars m 2, can be made at a height equal to the height of the corrugation of the corrugated fence b and installed with the possibility of contacting the edges of the loops 8 with the protruding edges of the corrugated fencing 6.

The contacting of the edges of our welders 8 with the edges of the corrugated fence 6 protruding upwards is made to limit the tilt-skew of even girders 2 when the fence is deployed. When the support member 14 is made of a channel with a horizontal transverse size not exceeding twice the height of the purlin 5, the moment from the transverse effect of the even crossbar 2 on the braces 12 is compensated by the moment from the eccentric displacement of the hinge 15 from their longitudinal axis. Crossbars 1 and 2 are made of I-beams, purlins 5 are made of channels, braces 12 and the lower rods of Sa 13 are made of corners, and columns 10 are made of box-section steel. Hinges 3, 4, 9, 11, 15 and 17 are made of standard bolts, corrugated fences - from metal roofing sheeting, and slats 7 and 8 - from sheet steel.

In the folded position, the structure has the form of a compact package with horizontally arranged columns 10, diagonals 12, and lower rods 13. Runs 5 and corrugated fences 6 are located in a vertical position and tightly abut each other.

When mounting the collapsible canopy, columns 10 are freed from fastenings with odd bolts 1 and transferred from a horizontal position to a vertical position (under its own weight, on the hinges 9) together with folded braces 12 and the rod.

Before unfolding the fence, the extreme columns 10 are placed in working position on the foundations, made at the same level with the floor, fixedly fixed to them, and 5 are then fixed on the top with crutches. Next, the design is released from fasteners in the area between the extreme (first) and the next (second) column

10i, supporting the crane with a crane, stretch the cell with 10 winches, while the crane displaces

in parallel with the moving part of the structure. In the process of unfolding the cell, the braces 12 rotate on the hinges

11 and 15 from the vertical position to the inclined working position, the lower bars 5 of it 13 and 13 swivel on the hinges 11 and 17 from the vertical position to the horizontal, and the girders 5 turn on the hinges 3 and 4 from the vertical position to the horizontal with the offset ball 20 bolt 2 down to the interaction of its support elements 14 with the upper ends of the diagonal bars 12, and the vertical position of the bolt 2, preventing it from misalignment and sticking in the final stage of unfolding

25 cells, is provided by the interaction of the lath 8 with corrugated fences 6. After securing the second columns 10 on the foundations, the remaining cells of the folding canopy are similarly and successively unfolded.

When dismounting a folding canopy, a jib crane is used, while the auxiliary hook of the jib raises the even bolts of 2 collapsed cells, and the main hook of the crane supports the shifted 35 part of the collapsible canopy, initially for the odd odd bolt 1, then for even bolts 2 already folded cells. The horizontal movement of the folding cells is carried out with a winch, while the crane is displaced in parallel. In the process of folding the cell, the girders 5, the braces 12 and the lower rods along the ca 13 turn on their joints 3, 4, 11, 15 and 17 from the working position to the vertical position. As they are folded, the folded cages are successively fixed between each other by fasteners along the columns 10 and even bolts 2. After the entire roof has been folded, the column 10 together with the articulated joints with the folded braces 12 and the lower rods 13 rotate

50 on the hinges 9 from the vertical position to the horizontal one by turning the boom of the crane and simultaneously lowering its hook and fixing it with fastenings with extreme odd bolts 1.
