The pergola consists of the following parts:

Columns

Horizontal beams

Trellis

 

COLUMNS

The columns consist of two beams 4,5 x 14,5 cm in height, 230 cm in height and three beams of the same cross-section and 30 cm in length. The three beams are mounted on the two ends of the column and in the middle thereof and are joined by the two beams with two 8X80 screws on each side of the column.

HORIZONTAL BEAMS

The horizontal beams of 4.5×10 cm are placed on the vertical columns in the slot left therein as the tank is positioned 7 cm below the end of the column. The horizontal beams are joined by columns with 8X80 screws.

TRELLIS

It is made of timber cross section 10X10 cm. At the intersections the timber has been removed from both parts so that one wood is contained in the other. It is mounted on horizontal beams with screws. These woods create openings of 60×60 cm.

BACKPACK BASES

For fixing the instrument to the ground, each pair has a pair of mounting bases.

The mounting bases consist of two galvanized metal plates and then painted with electrostatic paint, of a shape “P” and approximately 100x12x4 cm thick and 0.5cm thick, which “embrace” the column and are joined by passing screws 5 / 8 ″ X15. At the bottom there is a metal flange to hold them in the concrete pit.

Only ground irons, which hold the column at least 5 cm above the ground, are prevented from being ground in order to prevent the wood from being eroded by soil moisture.

TIMBER

The wood used is composite non-stick Swedish pine timber, in accordance with EN 351. It is manufactured with special compound (welding of wood) in different sections depending on the intended use.

COMPOSITE wood is 40% stronger than whole wood. It has a strength of 360 kp / m2 and a specific weight of about 480 kg / m3.

 

It contains about 15% moisture

Contains minimal juices (resin) compared to other pine family trees in other countries (weather in northern Sweden up to -25 ° C)

It has a thermal conductivity of s = 0.10 Kcal / Mho and sound insulation 3.5 times greater than concrete or bricks of equal thickness.

It has antimagnetic properties and is a poor conductor of electricity

It is resistant to fire and is classified in categories F30 and F60 (by DIN 4120) according to its cross section.

When the outer part of the cross-section burns, its interior protects and retains its durability.

It is processed just like commercial wood

It retains its shape and distorts or creates minimal fractures

Annual wood rings are usually perpendicular to the long side of the cross-section with a significant increase in the mechanical strength of this surface when applied to floors.

All corners of the wood are planed with a radius of about 5 mm.

METALLIC ELEMENTS

The metallic elements used in the manufacture of the equipment (screws, connectors, etc.) are made of metals either thermo-galvanized or electro-galvanized, where the surface preparation has been preceded by sandblasting or stainless steel. The dimensions and cross-sections of the metallic elements are sufficient to accommodate (with an appropriate safety factor) the loads for which they have been designed to withstand corrosion and adverse weather conditions.

PAINTS

For their anticorrosive protection, the metal parts are processed to release them, followed by a coating of polyzinc (zinc) and then electrostatic, two-layer polyester powder coating.

All production work processes for the processing of raw materials are carried out according to:

The ISO 9001: 2015 quality system

The ISO 14001: 2015 Environmental Management System
