The concrete hemisphere is mainly used to prevent vehicles from parking in undesirable places. Due to its simple form, functionality and affordable price, the product is in demand. The hemisphere (nadolb) does not interfere with the movement of pedestrians. If necessary, cyclists can go around it, but for an ordinary car, such an element on the road becomes an insurmountable obstacle.
Destination
In places where there is constant heavy pedestrian traffic, it is simply necessary to limit the flow of vehicles. In conditions of shortage of convenient parking lots, there is a problem of violators of parking rules. Transport is placed on playgrounds, sidewalks, flower beds, lawns.
Owners of shops, offices, restaurants and cafes, shopping and business centers are fighting violators by installing concrete products to prevent vehicles from entering unwanted territory. Such restrictive road elements are also needed near kindergartens, schools, clinics, hospitals. Most often, decorative flowerpots, flowerpots, benches or just posts are used for these purposes.
One morea concrete hemisphere can serve as such an element. It will not only limit the passage, but due to its simple and natural form, it does not require design solutions when placing. Even in large quantities in a limited area, such elements look quite organic and do not hurt the eyes.
They can be massive and permanently located in places of constant travel restrictions. In another case, when it is necessary to temporarily create new parking spaces or, for example, change the order of traffic or the direction of movement during mass or sports events, it is advisable to use smaller hemispheres to facilitate work and convenience.
Benefits
Fences for parking spaces in the form of a hemisphere, in comparison with conventional posts or decorative elements made of concrete, are more resistant to vandalism. They are quite difficult to break intentionally without a special tool. In case of accidental collision even with heavy vehicles, the shape will not suffer. The material ensures a long service life.
Due to its massiveness, it is problematic to move such a fence to free the passage, and in combination with an additional pin buried in the ground, this is completely impossible. At the same time, such elements are simply installed on the road. They are safe enough. It is difficult to accidentally injure them, since the hemisphere does not have sharp edges and protrusions.
The concrete hemisphere can be simple or have a decorative base-stand. Increasing the overall height of the limitercan be useful to prevent the arrival of off-road vehicles. Often, owners of jeeps and SUVs neglect standard height hemispheres. But a simple stand can discourage such motorists from venturing to park vehicles where they please.
Installation
The concrete hemisphere can be installed on various surfaces: asph alt, paving slabs, lawn, dirt road. The main condition is that the surface must be flat. The weight of the structure ensures its secure fixation.
In some cases, to prevent displacement, the hemisphere is equipped with a metal pin. Usually this is a piece of reinforcement, which is mounted in the base at the stage of pouring concrete into the mold. To install such a structure, it is necessary to make a hole in the road surface.
Use a puncher and suitable equipment. If the pin is immured into a concrete cushion, then the hemisphere turns into a stationary limiter. The only way to get her out of the way is through destruction.
To create temporary parking spaces or to restrict traffic, hemispheres are evenly distributed at the required interval on a section of the roadway and aligned along the line.
Care and maintenance
The concrete hemisphere is made of high quality concrete. Responsible manufacturers use clean alluvial sand and high-grade cement. To increase the technological characteristics, additions of fibers, plasticizers and other components are possible. This makes the products resistant toaggressive environments, adverse weather conditions, mechanical impacts.
Products can be painted with weatherproof facade paints to give the look. The most common shades are red, white, grey, blue and yellow.
Concrete products are unpretentious in care. It is enough to periodically clean them of dust and dirt with a stiff brush dipped in soapy water. If the paint coating is updated every few years, the hemisphere can serve for a long time without losing its properties and technological characteristics.
Forms for concrete hemispheres
Parking barriers can be purchased from the manufacturer or made independently in the required quantity. The technology of concrete products is not at all complicated and accessible to almost anyone interested. It is enough to have a concrete mixer, purchase material and a high-quality form for a hemisphere.
It is usually made of high strength plastic 2-3 mm thick. The spherical design makes casting removal easy. The form can serve for a long time. At the request of the customer, manufacturers can produce fences of different sizes.
The greatest demand is for forms with a diameter of 50 cm and a height of 25 cm. The weight of such a gouge will be up to 80 kg. From sand and concrete, mixed in the required proportions and closed with water, a concrete solution is prepared. It is poured into the mold and aged in it for at least a day. After that, concrete products are carefully removed and left to age and dry.
Alsouse molds for hemispheres with dimensions (diameter × height): 40 × 20 cm, 42 × 24 cm, 50 × 30 cm, and massive barrier structures 70 × 35 cm.
