Characteristics Structures
_________________________________________
- Fixation of the Area
For the fixation of the greenhouse to the area, we will use a system of pikes, which allow us the anchorage the area without the need to realize a foundation.
Central pike: in galvanized steel Ø 60 mm.
- Arches
The arches are realized in pipe Ø 60 x 1,5 mm. and galvanized steel Sendzimer Z-275. Curled according to model tunnel for the different dimensions of width that we have.
- Reinforcements
The greenhouses type tunnel present several reinforcements, which improve the stability of the whole structure:
-Straps.
The straps fulfil in pipe Ø 32 x 1,5 mm and they will place to the lengthways of the greenhouse, forming 3 lines, reinforcing the top part and the wings of the greenhouse.
-Reinforce in V.
They are reinforcements that put between the first and second arch, of both heads of our greenhouse, forming a form of V. These reinforcements are pipes of Ø 32 x 1,5 mm. And subject to pipe of arch by means of clamps of head Ø 60 mm.
-Bars of Culturing.
The bars of culturing, there will be included always in the greenhouses tunnel of 8,50 and 10,00 m. Of width, in other measures (5,10 and 6,80 m.) they will be included only for the entrusts. The bars of culturing form for a bar of pipe Ø 32 mm. In galvanized steel, and his correpondents pendulums in pipe of Ø 32 mm.
- Coverage
This way for the fixation to the arches of head of the structure:
Combine clamp steel - plastic Ø 60 mm.
Clamp steel Ø 60 mm.
Clamp P.V.C. Ø 60 mm.
For the fixation of the plastic to the altar frontals, we will use:
Combine clamp steel - plastic Ø 32 mm.
Clamp steel Ø 32 mm.
Clamp P.V.C. Ø 32 mm.
- Altar Frontals
Several options exist for the altar frontals of this type of greenhouse, according to the needs of every client.
- Fixed altar frontal. It is a system of fixed altar frontal, which does not allow the step.
- Flip-top altar frontal. It is a system of altar frontal, which allows us to open the greenhouse for the step, this way like to ventilate it or for the entry of small machinery, and tb it allows us the entry to the greenhouse by means of a small pedestrian door when frontal this one this closed.
- Altar frontal with Sliding Door. It is a system of altar frontal, that even being fixed, incorporates a few doors of type sliding panel (for that of 5,10 m. Only incluiria a leaf of door, for the rest of measures incluiria two leaves), allowing this way the pedestrian entry, of machinery and the aeration of the greenhouse.
- Systems of Ventilation.
Several systems of ventilation exist for the greenhouses type tunnel:
-Half moon of Aeration; it is the most usual, and is in the habit of being included by the flip-top altar frontals (to esception of the tunnels of 5,10 m. Of width, which is not in the habit of being included.); they allow us to control the entry of the air for the heads of the greenhouse.
-Ventilation of Transom; it is a system of ventilation to place in the cumbrera, with an extent of 1,50 m. And with a length of 4,00 m. There will be able to be placed several modules of this type of ventilation, always of 4 in 4 m. this type of ventilation allows us aireation the greenhouse on the part wings - superior of the same one.
-Roll-up lateral ventilation; it is a system enrollable, that allows us the aeration of the greenhouse for the lateral zone, managing his opening by means of a system reducer of manual or automatic type.
