The main part of the construction of any fence or fence are supports, poles or special racks that are mounted to spans. Today there is a wide range of various materials that are used in the manufacture of fence racks. These are asbestos -cement and metal pipes, and concrete and wooden pillars, and special concrete blocks that are designed to build fences. Also, fence pillars can be made of stone or glass.
Installation of the fence, as a rule, begins with the fact that the flight of the fence is installed. Remember that when installing almost any supports for fencing, careful preparation is needed. First of all, it is necessary to mark the site, then you should dig out the recesses in the ground, and then dig a ditch under the foundation and install the pillars. After this, the base must be fixed with the foundation. It is advisable to protect the columns from the occurrence of rust – they are usually covered with a special mixture and covered with steel plugs to prevent moisture. Remember that even for asbestos -cement pipes, special protection against dampness is needed. Wooden columns must be protected from the harmful effects of the environment, for this they are covered with special impregnation, a layer of resin and bitumen is applied to them. It should be borne in mind that the diameter of the columns should be at least 14 centimeters.
Not so long ago, designing engineers and construction technologists developed a fence screw stand, which made it possible to significantly reduce the cash and time costs of building fences of any type. Their installation is quite simple, it is allowed to get rid of concreting columns, drilling trenches in the soil, as well as from filling the foundation. The technology of screw racks can significantly lower the harm that is caused in the process of performing work to the surrounding soil. You can also use screw racks to install greenhouses, hangars, road signs, pipelines, advertising shields and other construction systems.
The main advantages of screw racks for fences are the following:
1) screw racks are great for any type of soil, they are perfectly installed in very dense soil;
2) screw racks are installed with optimal accuracy of the plan prepared in advance;
3) this equipment is easily mounted without harming the surrounding landscape;
4) screw racks are reliable, durable and have a long service life (their service life is more than 30 years);
6) screw racks are mounted without the use of moles, as well as other devices, which completely eliminates all the stages of any work with the soil;
7) screw racks do not need concreting, which significantly reduces the cost of work at this stage;
8) the installation of one rack, as a rule, takes 25 minutes – this means that temporary costs will be significantly reduced for the construction of the fence;
9) screw racks can be used many times, without much effort, moving them from place to place;
10) installing screw racks is possible under absolutely any weather conditions.
The design of the screw racks has special fasteners, due to which there is no need to use welding when installing the fencing jumpers. The installation of the fence can conditionally be divided into four stages: first markings are applied, then the racks are installed, the fasteners are installed and the fencing flights are assembled.
It should be noted that marking is carried out in several stages: the marking is initially applied to the closing and corner racks. After that, places for racks, gate and gate are determined, then the marking of flight racks is placed then. The installation of racks is performed using the mounting key, a special plate-adapter of the required size is mounted on it, after which the screw stand is inserted into the key. A screw stand is installed along with the key in a place determined by marking. The rack after that is rotated clockwise so that it comes to a depth of 1.5 meters into the soil. After installing the rack, it should be closed with a plastic lid in such a way as to exclude precipitation with a hit. Fasten elements are selected depending on the material and the design of the fence. The use of fasteners greatly facilitates the installation of fencing jumpers. The final stage is the installation of span span, which can be made of wood, corrugated board, PVC, rabits and so on.
