Stable development of business in the field of construction of low-rise housing pushed the construction materials market to growth. Today, do not count the various large and small companies that produce construction materials. Therefore, competition in this area is very high. However, a good niche with a good growth potential is the creation of a small enterprise for the production and installation of enclosing structures. It is worth paying attention to the construction of concrete fences, since the cost of such fencing is not high. If the activity is correctly planned, then the costs can be recouped during one summer season. However, before you start this business, you need to build a concrete fence with your own hands for yourself.
Made with modern technology, concrete fences have an aesthetic appearance and fit into any landscape.
. What are the advantages of the concrete fence
? Before explaining the nuances of the construction of concrete fences, you need to consider all the obvious advantages of this type of fencing. Today there is an established stereotype of a negative attitude to concrete fences, despite the fact that they have a number of undeniable advantages over fences made of metal or wood.
Modern state-of-the-art technologies enable the construction of aesthetic and at the same time sound concrete fences:
- Right on the site of the construction site.
- Save resources on renting a crane and transporting building materials instead of ready-to-install blocks.
- Fit the fence without any problems, as it is very easy to do.
- Combine the height of the entire structure.
In addition, concrete structures have a sufficiently high strength and durability incommensurable with other materials. Made with modern technology, concrete fences have an aesthetic appearance and fit into any landscape. They look equally good in combination with brick buildings and wooden houses. Such a fence will look great, both outside the city and in the city.
What materials and tools are needed for the construction of the concrete fence
In order to manufacture a concrete fence, the following tools and building materials should be prepared:
- Special molds for casting fence parts that can be purchased from a store or manufactured independently.
- The required amount of steel reinforcement or fittings made of fiberglass. For sampling, its diameter should be 4 mm, and for bars 8 mm.
- Fine crushed stone from 2 to 6 mm.
- Washed river sand.
- Portland cement is not less than 500 marks.
- Any plasticizer.
- Concrete mixer and vibrating table.
Such molds for casting fence parts can be purchased at the store or manufactured by yourself
Such an adaptation as a vibrating table can be made by yourself or bought in a tool store. In order to make it yourself you need to have the skills of a welder, buy a profile pipe, a vibrating motor and all the other parts. It will cost less than buying a ready table. Calculation of the overall dimensions of the table should be calculated independently, taking into account the weight of the mold into which concrete is poured. Vibromotors on sale are different, produced by different firms. Among domestic products it is possible to choose motor ИВ-99Е.The vibrating table for making a concrete fence makes it possible to compact the solution to such an extent that its strength increases severalfold. If this is not done, then the building will not last long.
So it looks like the most common shaker for compacting reinforced concrete products
The technological process of manufacturing concrete slabs
Let's consider the whole process of manufacturing concrete concrete fence parts in order. At the initial stage, small granular gravel is loaded into the concrete mixer, which must be filled with water and rinsed of dust and dirt. Then the water is drained, and sand is poured into the container, which is mixed with cement and pure water. The recipe for the preparation of a solution for filling molds is developed by the individual himself, since it depends on the type of a particular fence. Often such recipes are available from sellers who sell forms.
The form is placed on a flat pedestal or platform and lubricated with a special lubricant, which is designed to prevent the adhesion of concrete to it. Inside the mold it is necessary to mount the frame from the reinforcement. It is needed to increase the reliability of adhesion of solidified concrete. Depending on the shape of the mold, an appropriate reinforcement scheme is developed for it, if it was not offered by the manufacturer.
The prepared solution is poured up to half the volume into the mold, which is then placed on the vibrating table. Primary compaction of the mass takes place on it. When pouring it is necessary to take into account the circumstance that the parts will need to be fastened together by some kind of device. After the initial compaction, the mold is poured over and leveled with a trowel or spatula.
After the concrete dries, it is necessary to finish the product without removing it from the molds. The surface must be grinded by hand or by a grinder to the ideal condition. Such a construction will have a standard form.
At the end of the whole procedure, the finished product is taken from the mold. This is a very critical moment in the entire technology of making a concrete fence with your own hands. This procedure is called stripping. Formwork is manually or mechanized, and its correctness depends on the qualifications of the workers.
After that all the components of the concrete fence can be considered ready. They only need to be checked for a marriage that needs to be corrected. The prepared components are fastened between pre-installed posts.
The concrete fence does not have to be gray
Before reusing the mold, it must be thoroughly cleaned of the remains of frozen concrete. One form, according to the manufacturer, can be used at least 300 times. However, practice shows that more than 200 - 250 times no form can withstand.
Manufactured concrete fences are not subjected to thermal effects to improve strength. Full solidification of the product should take place under some canopy or in a warehouse. The finished products are stacked horizontally, where they are finalized to the required condition. When freezing, the outside temperature should not be below 5 - 9 degrees. This is the lower limit, otherwise for the quality of the product no one can turn out. Thus, the technology of making concrete fences should be mastered in the summer. In winter, production must be transferred to a heated room. In order for the products to take the necessary strength, they should receive an exposure of at least 6 to 30 days, depending on the humidity. Installation of concrete fence is made between poles, which also have a concrete base.
