Shelter 1 .The length of the shelter of the type typically chosen equal to 2-3 m, and the width-0,9-1 m.

When producing cover segments rod, wire or pipe length of 1.6-1.8 m is bent in arc and ends deepenedin the ground by 10-15 cm. The distance between two adjacent arcs are usually made in equal 60-80 cm. Maximum height of the arcs above the ground will then be equal to 45-60 cm.

In the manufacture of the frame of twigs arc doing the same size.The rods are bent and their ends are stuck in the ground on both sides of the beds.You can make an arc from rods, consisting of two parts.To do this, take two rod length 1-1.1 m, their lower, thicker ends of the stick into the ground, and the upper, thin, bent toward each other, intertwined and associated soft twine or wire.The junction rods wrapped with a bandage or adhesive tape to the film at this point is not damaged.Dougie from rods set at a distance of 40-50 cm from each other.

For ease of use, the shelter can be made portable by using extra-base - a re
ctangular frame of appropriate dimensions, made of wooden slats section 40x30 mm, connected in the corners of the frame vpoldereva.In this case, the arc does not bury in the ground and are inserted into holes drilled into the longitudinal sides of the frame (Fig. B).

to provide rigidity and stability of the frame, and that the film does not sag from the top of the arc associated with each other strong synthetic twine (string), wrapping it around each of the arcs, or tie them to the appropriate length of the longitudinal rail section 30x20 mm.Twine and pull tight on both sides with a tie driven into the ground with wooden stakes or metal hooks.

arched frame cover:
and - frame stationary shelters: b - the frame of the portable shelters;in - appearance (cover assembly)

manufacturing a skeleton covered with translucent film width of 150-160 cm. The length of the film should be sufficient to overlap the side and end surfaces of the shelter.The remaining portions of the side surface of the film close overlap sides with shelter or free edge of the film Face tie into a bundle and tie with string to stakes driven into the ground with the mechanical side cover (Fig. B).The longitudinal side faille film pressed by a load covered with earth or nailed to wooden slats through the thin slats section 20x10 mm.

for additional fastening of the film to avoid being swept away in the strong gusts of wind, in this and other buildings protected pound can be used by ordinary clothespins best wood.They are convenient to attach the film to the wire arcs and other elements of the framework.

more convenient and practical, but more time-consuming to manufacture portable arched shelter with arcs of wire or pipe and the base of the frame of the rails can be made as follows.The width of the film every 40-80 cm of its length a sleeve made of 10-20 mm diameter wire and using a diameter of 30-40 mm, using pipes.For bubble at this point in the transverse direction is folded and sealed (with a ruler) narrow seam width of 4-5 mm, departing from the dual edge of the film to 15-60 mm so as to obtain the diameter of said sleeve.

The sleeve insert pieces (segments) wire or tube whose length should be 4-6 cm larger than the width of the film, at the same time, the ends will extend beyond the film to 2-3 cm. In the manufacture of wire segments cover (pipe) is bentin the form of an arc, and their protruding portions are inserted into holes drilled into the wooden slats of a base.Mechanical side sealed foil structures in the same manner as in the above-described shelters, or left open.To care for the plants and airing one of its sides is lifted.

Shelter 2. Easily collapsible shelter length 2.5-4 m, a width of 1-1.2 m and a height of 0.7-1 m can be done for 1.5-2 hours in the presence of several segmentstubes with an internal diameter of 10-20 mm and a length of 40-60 cm and a removable arc made of various flexible materials lengthy.

tubes may be made of brass, duralumin {old clamshells), steel plumbing, as well as black plastic or fiberglass with a wall thickness of 1-2 mm.

arcs made from any flexible material having a suitable cross-section, the ends of the arcs can be inserted into the corresponding tube.For arcs, you can use pieces of old electrical cable, electrical wire segments thick insulation, steel rod or a thick steel wire rods of willow, willow, hazel, poplar, thin, flexible plastic or fiberglass tubes, various fiberglass profiles, such as T-shaped.

collapsible shelter with metal tubes and removable arcs:

and - frame cover (view from the end face);6 - Mount the arc tube: / - a metal tube;2 - arc;3 - ridge element;4 - fixing wedge

Making frame shelter follows.Prepare the required amount of fresh tubes and plug them into the ground in pairs along the longitudinal sides of the beds to a depth of 15-20 cm. Prepare the appropriate number of arcs and stick their tube, as shown in Fig.a.Ends arc secured within the tubes by means of wooden wedges (Figure 6).Give equal elliptical arcs (oval) shape.On top of the ridge cover fixed element made of wooden slats section 25x25, 25x30, 30x30 mm.Rail tie with string (string) to the arcs of the framework.

end wall of the shelter covered with polyethylene film or nonwoven covering materials, When sewing it to the extreme arcs thread.The flag of the film is attached to the arcs clothespins, and its longitudinal side edges secured by conventional methods: boards, sticks, earth, etc.

Shelter 3 (temporary arch).The simplest arch Tunnel shelter length of 2-4 m, width 0.9-1.2 and 0.9-1 meters in height can be made of wooden slats section 30x30 or 30x40 mm or thin poles with a diameter of 50-60 mm (for the manufacture ofstruts, braces and ridge element) and several sections of steel rod with a diameter of 5-6 mm or thicker wire (thick insulated electric wire) for the production of arcs.

for manufacturing a skeleton take two rail length 1-1.2 m, designed for racks and plug them into the ground w depth of 25-30 cm in the middle of each end side of the beds.

Racks strengthening braces from 1-1.2 m long rails that are nailed to studs with nails, as shown in Fig.6. To the upper ends of the legs nailed ridge element whose length is equal to the length of the bed.

of segments of steel rod (wire) is bent arc, the shape of which is shown in Fig.8. Arcs in their lower recommended to do with vertical walls.The amount depends on the length of the arcs beds (shelter).They are recommended to have a distance of 0.7-0.8 m from each other.

ends arcs stuck in the ground along the longitudinal sides of the beds, they are tied to the top of the ridge element durable string (string).

for ready frame of the film throws cloth.Top film is attached to the arcs clothespins and below the edges of the longitudinal side walls of the shelter sprinkled the ground.Face side cover is not closed.

With a length of 2-2.5 m cover more appropriate to establish a third-pillar at the center of the beds.

the winter shelter dismantled, untie the arc of the ridge member, pulled out of the ground and removed for storage.Racks and ridge element can be left in a bed.

Shelter 4. This portable (collapsible) arched shelter with arcs of steel rods much like the shelters 1, 2, 3, however, it is more perfect and convenient.Its difference is the method of attachment to the arc ridge element and a design feature - the fact that it applied to the wooden box of the boards is not only for the protection of the beds, but also is used to secure the ends of the arcs on its longitudinal sides.

Shelter, as usual, is calculated on a bed and has a length of 3-4 m, a width of 0.9-1.1 m and a height from the surface of 0.8-1 m. However, its length and width can be increased without changing thedesign to 5 m long and 1.4 m in height.Exterior cover is shown in Fig.a and sketches its components - in Fig.b.

to manufacture the frame cover required: 2 boards in length of 3-4 m, and 2 boards in length 0.9-1 m, all 20 cm wide and a thickness of 25-30 mm, box;4 rail segment length of 30-40 cm and 40x40 mm sections to strengthen the box;2 rail length 1.1-1.2 m, section 40x40 mm for racks;4 rail length 1.1-1.4 m section 40x20 or 40x30 mm for braces;1 rack length of 3-4 m, section 40x40 or 40x30 mm for skating element;5-7 pieces of steel bars (steel wire) with a length of 2.2 m and a diameter of 5-6 mm arcs.

Before the construction of the shelter prepare and mark out the area for its location.The soil is removed from the edges of platforms (shovel) at its middle.

of two longitudinal 1 and lateral 2 boards do box, connecting at the corners of the board and vpoldereva fastening nails or screws.The corners of the box reinforce rail segments 3 located inside.The box is mounted on a bed, 3 pieces of rail bury in the ground.

In the middle of each lateral side of the beds is driven into the ground the rack 4, which is disposed within the box and nailed to the cross boards box 2. Supports strengthening braces 5 are also recessed into the ground and nailed to the cross boards 2 boxes outside.With this method of installation and the mounting of the frame 3, 4, 5 to carry on hiding place drugre land from them shovel, pick up a box and buried all the elements pulled from the ground with him.

Arched collapsible shelter with arcs of steel bars:

and - appearance;b - sketches of nodes 1, 2 - a longitudinal and transverse boards;3 - rail segments;4 - Front;5 - struts;6 - U-shaped bracket;7, 9 - ridged element;8 - steel rod segments;10 - C-shaped brackets

To these elements do not rot in the ground and cover it easier to transfer to another location, rail segments 3, 4 and strut braces 5 are not bury in the ground, but only nailed or screwed to the screws7 longitudinal and transverse boards 2 boxes.Additionally rack 4 may be attached to the transverse boards by U-brackets 6, made of duralumin or steel strips of width 20-22 mm and a thickness of 1-1.5 mm.

prepare and try on rail designed for skating element 7 and mark her place for arcs.Arc located at a distance of 60-80 cm from each other.For example, to cover a length of 3 m take 5-6 arcs, while the length of the cover 4 m - 6-7 arcs.The last arc located at a distance of 1-2 cm from the edge of the rack along its length.The marked locations are drilled through holes, through which will take place steel bars.Their diameter should be such that the bars designed for arcs fit snugly, but without much effort.

Similar holes are drilled in the upper edges of the longitudinal board boxes, using the ridge element as a template.The depth of the hole should be 6-8 cm. For the correct holes and drill at the same depth it is advisable to set the limiter.: As the ridge element can be used instead of the rail board length of 3-4 m, a width of 10-12 cm and a thickness of 15-20 mm.To a ridge element of middle arcs board 9 is secured by a C-shaped bracket 10 made of duralumin or steel strips of width 20-22 mm and a thickness of 1-1.5 mm, as shown in Fig.6, the node B.

of the segments of the steel rod bent the arc 8, the shape of which is shown in Fig.a.For ease of use make the oval cover an arc at the top and bottom with vertical sides.

When assembling the skeleton arc alternately inserted into the holes made in the skating element prepared assembly is mounted on a platform placed on a box and it ends arc inserted into the holes provided in the longitudinal boards boxes.The ends of the ridge element slats nailed to the upper ends of the legs.

Unless bars of desired length can be used, two separate sets of half-arches made of rod segments half the length.In this case, the ridge element drill double amount of adjacent holes.Before installing the half-arches ridged element is nailed to the posts and the ends of the half-arches alternately inserted in the holes of the left and right longitudinal boards and then into holes drilled into the ridge member on both sides.

If necessary, the arc (semiarc) fixed in the skating element screws.

on the longitudinal sides of the arc of cover pull cords are strong that the film does not sag.

After the carcass of his wooden elements impregnated with bitumen petrol antiseptic and double-color light oil paint.Steel arc also cover paint for metal structures.

Ready frame adhesive qualities of the polymer film.His best end walls obtyanut reinforced polyethylene film.The lower edge of each of the cloth, intended for the end wall, nailed.

Shelter 5 (cable-stayed arch).It is quite simple and good cover, which is required for the construction of a small amount of construction materials, can be made on the type of cable structures.Shelter has a length of about 3 m, a width of 0.9-1 m and a height of 0.7-0.9 m. For its production need two pieces of steel rod or coiled reinforcing steel rod with a diameter of 5-8 mm and a length of 1,82 m and a coil of soft annealed steel wire with a diameter of 2-3 mm.

of bar bend two identical arch height of about 1 m and the desired shape (in the form of semi-oval, semicircle or semi-ellipse) and stick them in the ground to a depth of 20-25 cm at a distance of 35-40 cm from the end side of the beds (Fig.).In the middle of the sides with sturdy beds clog wooden stakes or metal hooks, and then pull the three longitudinal stretching of the wire (guys).First, pull the top (center) stretch.To do this, the first Coke tied one end of the wire, then swing the wire around the first (near) the arch in its upper part, and then around the second arch and tied for the second Coke.Similarly pull two longitudinal extensions, arranged symmetrically on the upper and lower stretching it by 20 cm. The upper wire is tensioned so that the arches have been rejected to the ends of the beds to 20-25 ° from vertical, and the wire was stretched sufficiently strongly to allthree sites.Streamers tied to the arches frame the soft copper wire.

Additionally arch tied to stakes driven into Heed at their ends, soft copper wire.Earth around the arches and pegs compacted.

Arched guyed shelter:
a - a view of the arch from the end face;b - side view of the cover: 1 - arc;2 - stakes (hook);3, 4 - wire stretch (guys)

middle cover transverse pull cords that are tied to the longitudinal stretching.The ends of the cords tied to stakes driven into the ground with the longitudinal sides of the beds.

on the frame snapped one whole cloth film.Face side of the cloth is collected into a bundle and tied to stakes placed with.sides with beds.The longitudinal edges of the cloth sprinkled the ground or press down with stones.
