Rope ladder - a convenient and necessary inhousehold device. When folded, it takes up little space, but if necessary, when other boosters design for any reason can not be applied, it always comes to the rescue. Rope ladder is indispensable in case of repair inaccessible areas on the roof. Without it will not be enough if there is a need to go down a narrow well. In the same house, where there is a child, this ladder will perform the function of sports equipment, becoming the favorite toy baby. We propose to consider three of the most easy-to-manufacturing versions of the rope ladder, to put into practice that anyone is capable of.
Rope ladders consist of two mainelements - steps and ropes. Some craftsmen everything for home-made rope ladder fit spade handles, which get in the horticultural or construction centers. Instead of wooden slats is also convenient to use tubes made of plastic or light metal alloys. Regardless of the stage of manufacture of the material should not have sharp edges, which may interfere with the movement and injure humans.
In most cases, the ladder is made of wooden bars thickness 4.7 mm circular or square cross section
Ropes for hanging ladders made abased on natural and synthetic materials. Natural fibers of flax, hemp and cotton are durable. They are excellent for arranging the "Swedish" wall and a sports area. Synthetic materials such as nylon, polyester, nylon considered more practical as different wear resistance and increased resistance to stretching. In addition, they are known for resistance to solvents, including turpentine, gasoline, and alcohol. Synthetic materials do not lose its properties even when wet.
The optimum thickness of the ropes for a rope ladder - from 7 to 9 mm. Ropes of this thickness will not cut the hand during operation and at the same time provide sufficient reliability of the design.
The choice of materials rope ladder depends on the purposes for which the product will be used: for working outdoors or indoors in dry or humid environment
In any case the hanging ladder make longnot more than 15 meters, maintaining the distance between the steps in the range of 25-35 cm. As the rope ladder refers to the number of mobile facilities, the weight of the finished structure shall not exceed 20 kg. Suspended ladder, it is desirable to equip the stops, which would not allow construction to touch the wall. length of stops can vary in the range of 11-22 cm.
For the manufacture of universal design, which will be useful in the economy, we need:
- Two cutting strong ropes 20 m;
- 7 wooden strips 35 cm long and 6.3 cm thick;
- 1 roll of thick coarse yarn;
- Power Tools (Drill, Jig Saw);
- Fine sandpaper;
- Pila for wood construction and a knife.
All the cuttings, which will serve as aladder steps, are interconnected by means of two ropes. The surface of the cut cuttings should be polished. This will prevent further trouble as scratches and splinters in his hands. The length of the rope should be calculated taking into account that the ladder is two times shorter than in the final after making the knots form than the original length of the rope.
Make a sound and solid rope ladder, which will safely withstand the weight of an adult is fairly simple
To rope in the process of weaving is not dissolved,their ends need to singe. This can be done using a hot knife cutting material. Warn rope unraveling help and wrap the ends of thick coarse thread.
Getting Started. Before the first tie bar at the end of each of the ropes tying the loop diameter of 6 cm, for which we shall henceforth suspended ladder. Now we take the first step and tying a rope on it. Rope Fixing is carried out using the technique of knitting puncture-proof assembly "constrictor" which provides a very good fixation bars.
A visual guide to knitting site "constrictor":
Even fixing step by using a robust assembly"Constrictor" is always the possibility that the stage may slide. To prevent this at both ends of each stage is desirable to make the grooves. To prolong service bars, cuttings is desirable to cover paint or treated with a special compound that protects the wood, but it does not make it slippery.
At a distance of one to two centimeters from the edges using a knife first cuts do width 1.5 cm and depth of 3 cm. Of these small then forming grooves with rounded edges
Stepping back a distance of 25-30 cm from the first stage, the second tie bar. The same technology we fix all the other steps as long as the staircase reaches the desired length.
Before tying around each of the slatstight knots, make sure that the steps are arranged parallel to each other. After unleashing "constrictor" in order to re-twist assembly, extremely difficult.
Locate the stage at the same distance parallel to each other allows a special device: it is enough to fix the crossbar between the rails, and sticking on the outside edge of the tie with a rope
Alternately combining all stages, the ends of ropes and make out in the form of loops. As a result, should get a ladder about 11 meters long.
A feature of the second method of manufacturinghanging ladder is a need for making holes in the steps. Through them we reach the ropes, collecting all the rungs in a single structure.
In the proposed version, we will usewooden beams of square section length of 40 cm and a synthetic nylon rope. Each of the handle, departing at 3 cm from both ends, using a drill to make the holes with a diameter of 1.5 cm. After a couple of holes, do not forget to make sure that the diameter corresponds to the thickness of the rope. After that, the bar carefully sanded using sandpaper or a sanding machine, and treat with an antiseptic solution.
Nylon rope, a length of 10 m, cut into 2 equal parts. The edges of the handle coarse thread or a hot metal.
Getting to the assembly structure: on both ends of the ropes do loop or tie knots. The free ends of the rope is pulled through the through-holes of the first crossbar
During assembly design using all the same device, fixing a crossbar between the bars of wood nailed to a board.
The long "tail" of the rope we put into the loop,raised above the bar and wrapped around the rope assembly. The result is the first rung, fastened between the two nodes. The same technology and collect the remaining steps
In case, if there is no point or time to build a rope ladder with rungs, you can make the design, the role of the steps which perform knotted loops of rope.

Another interesting variant of stairs with "Burlatskii"loops. This weaving technique is good because the result is not a node, and a handy loop. The loop can be inserted into the legs and wrists, to bring to them the weight and rest when tired.
Making "Burlatskii" loop is easy: double-twist rope, forming something like a figure eight. The lower the "tails" Eight stretch, and stretch the circle formed the upper part of a twisted loop. After use, easy to untie the noose, the rope using for other purposes.

Knowing some simple secrets of weaving rope ladder, you will be able at any time to build a comfortable design, sometimes so indispensable in the household.
