IS STRUTS – STRUTS

The times when concern about human health in our country was a matter of state, has sunk into Oblivion. Quality free health care now depends on the good faith of the doctor, and paid from the amount You are able to “detach”, and even then not always. So I advise you to take care of their health themselves. As you know, the sister of health, physical education, and brother — sports and first assistants they have sports equipment. One such well-known and the simplest of structures is the bar — elastic crossbar mounted on the uprights.

 

In gyms beam installed on telescopic racks (for adjustment of its height), while they themselves stand are fixed by stretch marks.

 

In life, you will often see the crossbar mounted on two posts or between two trees.

 

The construction of the bar I “spied” a child’s swing set. They have no stands as such, but there are two pairs of struts, installed at the same angle to the vertical, supporting each other and the crossbar. Each pair are interconnected by spacers. Well, the underground part of the design I had to think out.

 

Strut stands made of steel water pipes with a diameter of 42 mm with a wall thickness of 2.5 mm.

 

At the top of the strut ends of the struts are connected using angle bracket (welded to it) in the middle part of the spacers (length of the same pipe), but closer to the lower end in the base part, and a jumper from the steel reinforcing bar diameter of 16 mm. Here note that the angle brackets were made from angle angle 40x40x5 mm, which was frezeruyutsya inner radius (to the brackets of the crossbar tightly posticalis brackets braced stands). The holes for the mounting bolts in the brackets abutting the drill at the same time.

 

The bar cut to size (1500 mm) from a thick-walled water tubes of an external diameter of 30 mm. Believe that this is the optimum thickness. If you take a thinner pipe, it may be of inadequate strength and rigidity, and thicker will be difficult to clasp the fingers lock. To the ends of the pipe welded brackets from the corner of 35×35 mm.

 

For mounting the strut-braced struts on the chosen place for each of the pairs arranged separate Foundation. Under the Foundation dug out a small trench dimensions 1000x500x200 mm (length * width * depth), and their bottom edges Deepens bayonet spade — square pits arranged under the lower ends of the strut-braced stands, and that they fall. We must try to distance between the posts at the bottom equal to the top gap in podstekolnoj the crossbar, and the crossbar is located horizontally. The pits filled up again with soil, rubble, brick fight etc. At this time you are reconciling the position of the strut stands vertically, backfill compacted. Next, the trench pour the concrete mixture, which is to save boticca — filled up by large stones.

 

Garden bar:

1 — cross bar (steel pipe 30×2,5); 2 — strut-braced stand (steel pipe 42×2,5, 4 pieces); 3 — spacers (pipe 42×2,5, 2 PCs); 4 — jumper wire (steel reinforcing bar of Ø 16, 2); 5 — the Foundation (concrete); 6 — backfilling of the pit (soil, gravel, brick fight, 4 items); 7 — bracket bar (area 35×35, 2); 8 — bracket braced stands (area 40×40, 2); 9 — mounting bracket crossbar and strut struts (bolt M8 4 PCs); 10 — natural soil.

 

To start using the bar only after two or three weeks, when the concrete attains sufficient strength, to not allow the rack to shift under load.

I must say that sports equipment is not only used for its intended purpose — for the physical charge in the early morning. Often fine days hang on him and swing for children — they even made their crossbar with ball bearings. The horizontal bar is often used for commercial purposes — it is convenient to hang the rugs and carpets for cleaning, and in Sunny weather to dry on hangers winter clothes, etc.
