SEESAW 10-05-03
The wooden saw is made entirely of composite Swedish pine wood.
It consists of an oscillating beam of 300x9x9cm, on both ends of which there are wooden seats 4,5x47x19cm fixed to the beam with 8×120 screws. At the top and bottom of the beam are mounted two wooden sections 9×4,5 cm in length and 100 cm in length. Their connection to the beam is made by means of chainsaws.
At the front of the seats is a “W” shaped aluminum handle with a cross-section of Ø 25 mm and an internal diameter of 15 cm for user retention. The handle is secured to the seats by means of a 3 / 8X70 screw.
The base of the saw is “P” shaped with two vertical parts made of 9x9x72 cm timber, the bottom of which is fastened to the ground by means of metal mounting brackets.
The vertical beams are joined together using a 15×37 cm wooden beam at the bottom.
Inside the horizontal oscillating beam where the shaft passes through it, bearings are mounted for the best oscillation of the instrument, and the outer parts are mounted “atalon” for greater stability and support safety.
Below the two ends of the saw, they are mounted by two elastic rectangular sections to absorb vibration during use.
BACKPACK BASES
For fixing the instrument to the ground, each pair of wooden pillars 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 “hug” 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 thermal conductivity s = 0.10 Kcal / Mho and sound insulation 3.5 times greater than concrete or brick of equal thickness.
It has antimagnetic properties and is a poor conductor of electricity.
It can withstand fire and is classified in categories F30 and F60 (by DIN4120) according to its cross section.
When the outer part of the cross-section burns, its interior protects and retains its strength.
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, if applied to floors.
All corners of the wood are planed with a radius of about 5 mm.
PLASTIC INFORMATION
The plastic components required to manufacture the equipment are highly resistant to UV radiation and adverse weather conditions. Preferred are recyclable materials such as polyethylene (PE) or polypropylene (PP). Specifically all screws protruding from the equipment over 5 mm are covered with polypropylene (PP) plastic plugs. They are also safe for the safety and health of children.
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, with surface preconditioned by sandblasting or stainless steel. The dimensions and cross-sections of the metallic elements are sufficient to receive (with an appropriate safety factor) the loads for which they have been designed to withstand corrosion and adverse weather conditions.
PAINTS
The varnishes and the colors that protect the wooden parts are specially designed for the climate of our country (temperature changes, open or closed areas etc.) are absolutely harmless to the users (they contain no lead, chromium, cadmium and other heavy metals) and give great strength to our constructions.
PACKAGING
The following procedure is used for fixing the equipment:
At this point where the column is to be placed, an 80 cm deep pit is opened. about 60cm in diameter. Then, once the column is inserted, the pit is filled with frusto-concrete concrete until it reaches 20 cm. from the ground surface, where it is covered with soil.
Only ground irons, which hold each column at a distance of about 10 cm from the ground, are prevented on the ground in order to prevent the wood from being corroded by soil moisture.
All production work processes for the processing of raw materials are carried out according to:
EN 1176 standards 1-6,
The ISO9001: 2015 quality system
The environmental management system ISO14001: 2015
