Arch for grapes: the choice of material and design, the rules of construction and manufacturing
The grape arch is a popular landscape design element. It serves as a worthy decoration of the backyard and plays the role of a support for the vine.
Peculiarities
The grape arch is a non-capital lightweight structure made in the form of arched supports fastened together and fixed at the base. The most complex models are open arbors, in which the vine plays the role of walls and roof. The choice of the configuration of the structure largely depends on the grape variety that is planned to be grown, as well as on the style in which the site is decorated. So, for heavy varieties, a wooden arch made of solid natural wood is suitable. Such a design, unlike metal and plastic models, will become a reliable support for fleshy bunches and will look organic with a lot of green mass.
In addition to wood, reinforcement, profiles and plastic pipes are used to make vine arches. But perhaps the most spectacular and aesthetic arches are made of wrought iron. The choice of material depends on many factors, the main of which is the functionality of the future structure. If it is supposed to grow varietal grapes, and the arch will play the role of a vineyard, then wood and metal are suitable as a material for the frame.If the arch is assigned the role of a support for decorative grapes, plastic and metal rods can be used. Such a design, entwined with a vine, will harmoniously fit into the landscape, and, in addition to decorating the site, will provide good shading.
When calculating the height of the arched structure, it must be remembered that if the arch is located next to the house, it is not recommended to make it too high. Otherwise, the overall composition of the site, the center of which is the house, will be violated. The optimal height is equal to the height of the ceilings of an average apartment, and is 265-280 cm.
If the arch is erected only for shading the house, then you can get by with a semi-arch, the end of the arc of which will be fixed on the wall or roof.
wooden structures
Wood is the most popular material for building arches, and is widely used both for decorating vine arrangements and as a working support for vines. Wooden arches fit perfectly into the landscape of the garden and are a worthy decoration of the yard. The advantages of the material are also its relatively low cost and wide consumer availability. In addition, a wooden structure, unlike, for example, a forged one, can be made with your own hands, without resorting to the services of professional craftsmen. Another advantage of such products is their natural origin. Natural materials add harmony to the decoration of the garden and look very natural.
The only drawback of wooden arches is their not very long service life compared to metal and plastic products. However, with proper wood processing and compliance with construction technology, the life of the structure can be significantly increased.This will require pre-treatment of wooden blanks with antiseptics and stain, as well as coating with moisture-resistant types of varnish.
Those sections of the structure that will be immersed in the ground should be wrapped with roofing felt and deepened by 60-70 cm. This will prevent the wood from rotting and give the structure greater stability.
In the process of burying wooden supports, compacting the soil should be done every 10 cm, and the distance between two adjacent arch elements should not exceed 60 cm. This applies to both longitudinal and transverse structural details, and avoids sagging of the vine under its own weight. Structurally, wooden arches come in several types.
- Arbor arch. It is perhaps the most refined and practical structure. It is a decorative building, furnished with items necessary for a good rest. Inside the gazebo, wicker furniture is often installed, lighting is provided and decor items are placed. More expensive buildings are equipped with ovens or barbecue areas. The role of the walls and roof in the arches-arbors is played by the vine, which grows together with other climbing plants. However, only species that are fully compatible with grapes can be planted.
- Garden arch. A simpler structure, consisting of several arcs in series, and equipped with a small wooden bench. Any person who has minimal carpentry skills and has the necessary tools can build such a structure.
- Semiarka. Usually installed along a sidewalk or fence. The design has only one support, and the wall of the house or the upper part of the fence is used as the second.Such models are the most budget option and are used in small areas or where it is impossible to place a full-fledged arch.
- Canopy. This type also applies to arched structures and is the best solution for summer cottages. The structure looks quite simple and is quite suitable for installation on a site that does not have a specific style direction.
plastic models
In the manufacture of arches, plastic water pipes are often used. Such structures are distinguished by a long service life, strength and low weight. In addition, plastic is one of the few materials that is not threatened by corrosion or decay. The assembly of the plastic arch is also not particularly difficult. Due to the presence of a huge number of connecting elements used to form the pipeline, the frame can be given any configuration and size.
Pipes can be bent using an electric soldering iron or a gas burner. To prevent creases inside the pipe, it is recommended to fill in dry sand. It is necessary to fix the structure in the ground by concreting or forming pillars. In the first case, it is enough to dig a hole, fill it with concrete and insert the lower part of the pipe.
When building columns, remember that their bases should go into the ground by at least 40 cm. The ground part of the pillars is formed by erecting the formwork and pouring concrete mixture into it. The arch frame is installed in the solution that has not yet hardened and, until the concrete has hardened, it is leveled using the building level.
After the composition dries, the ground part of the pillars can be tiled or decorated in any other way.
metal structures
Arches from metal differ in the high durability and long service life. The use of a metal profile in the construction of structures allows the frame to withstand significant weight loads resulting from the impact of heavy grape varieties. In addition to weight, metal arches withstand wind loads well and are highly resistant to mechanical damage. The disadvantages of metal structures are susceptibility to corrosion and the risk of sagging reinforcement bars.
It is quite simple to make an arch from metal even if there are no skills in owning a welding machine. There are several ways to build a structure without using welding. The first step in the construction of such an arch should be digging holes for supports. Their depth must be at least 50 cm. This requirement is dictated by the large weight of the structure, which requires serious reinforcement to ensure its stability. After the pits are dug, it is necessary to pour a concrete solution into them, and, after waiting for the composition to grab a little, insert the supports into it.
Metal hollow pipes or metal profiles can be used as supports, so that reinforcement can be inserted into them. The cross-sectional diameter of the rods is chosen independently, and depends on what load the frame will experience. If it is planned to grow ornamental varieties, you can take lighter and thinner reinforcement with a cross-sectional diameter of 12-15 mm, while for large-fruited species you need rods with a diameter of up to 18 mm. After the concrete has completely hardened and the supports are securely fixed, you can proceed with the installation of reinforcement.
In this case, it is advised to use two methods:
- the first is that the rods are bent along the desired radius and inserted from above into the support pipes;
- the second method consists in drilling horizontal holes in the supports and fixing the reinforcement in them with wire or bolts.
If the fastening is planned to be carried out using bolts, then the reinforcement must first be riveted and drilled at the ends so that bolts can be screwed in there. The distance between adjacent rods should be no more than 60 cm.
Upon completion of installation, the structure must be treated with an anti-corrosion compound and painted in the selected color.
Tips
Whatever material the arch is built from, you should know that when choosing a place for its construction, insolation and ventilation of the selected area should be taken into account. Grapes are a very sun-loving plant, so it is recommended to place the arched structure in the most illuminated place in the yard or garden. Care of the vine growing on the arch should be carried out throughout the season.
It is recommended to regularly trim the shoots growing to the side or redirect them in the right direction. For this, the technique of tying and pinching is used. Control over the state of green mass is due to the decorative function of grapes growing on arched structures.
The grape arch is a practical and multifunctional structure, thanks to which you can stylishly decorate a summer cottage, organize a comfortable rest area and at the same time provide excellent conditions for the growth and ripening of grapes.
