Scaffolding with their hands

many processes to be performed at a height, and therefore can not do without reliable forest During the construction of a house.The most optimal solution - to produce scaffolds with their hands, then do not have to pay the rent and to spend time on transportation design.They come in wood and metal, and depending on the material, assembly technique has certain differences.

Design and forest types

and wood, and metal woods have the same elements:

• support columns;
• stairs;
• decks and bridges for him;
• protecting railing;
• stops;
• horizontal and diagonal braces.

Wooden structures easier to collect - they are smaller in size, and all the details get off with each other nails.However, such woods are not intended for heavy loads, and their disassembly requires time and reassembly will be less robust, as the bars are in the nail hole.Metal scaffolding tubes is much stronger, they can easily expand, if necessary, and connection reliability is high regardless of how many times the disassembled construction and collected again.

Depending on the method of attachment are 4 main types of scaffolding.

Table.Types of forests

Types of Forests	Description
frame	metal structures of the vertical frame, held together by diagonal and horizontal braces.These forests have a low weight, are easy installation
wedge	very robust and durable design, all elements of which are fixed with special holders
pin	rarely used woods that are easy and build simple, stand very heavy loadsbut too expensive and have a lot of pressure on the ground
saddle	are universal forest, perfectly suitable for buildings with complex geometric shapes.The assembly process is time consuming, but if necessary, design a form easily changed horizontally and vertically

How to build a wooden timber

order on forests was convenient to work, between the uprights to be away from the 2up to 2.5 meters, the width of the deck is not less than 1 m and the total height of the forest -. max 6 m Based on these parameters, is about the design drawing.

To work required:

• timber 100x100 mm;
• board 30 mm thick;
• board section 100x50 mm;
• nails;
• hammer;
• level;
• roulette;
• circular saw.

Wood must be firm and dry, without cracks.Raw wood will weight construction, moreover, after drying may be deformed.Because forests are only required at the time of construction or home decoration, handle them with antiseptic compositions and do not need to be sanded.

Step 1: Production frames

4 timber cut on forest height and placed on a level surface.Now take 2 to 4 bar and 2 m, 3.6 m, and nail them to the inner side of the support beams: lower the upper edge 4 meter - the bottom.two identical trapezoid, which should be strengthened further by diagonal struts should get.

Step 2. Assembling the frame

Rama lift, installed vertically opposite one another and temporarily fasten the sidewalls: the distance between the lower edges of the rack should be 1.15 m, between the upper 1 m Check the location of the sidewalls of the horizontal building level.and if everything is correct, firmly knock the frame with nails.The finished design should have a pyramidal shape and strictly horizontal sidewall of the timber.

Step 3. Installation of flooring

to the upper cross-bars must be nailed boards for flooring.It is best to fill them in the frame width;boards are laid end to end, with no gaps at the joints.On the sides of the frame securing the additional cross member, which can be used as a ladder.

Assemblymetal scaffolding

in private construction is more convenient to use frame metal scaffolding with wooden decks.They consist of several sections, the number of which depends on the length of the building and its height.Suitable for the manufacture of sections of steel and aluminum strut;if assumed to heavy loads, it is better to choose the steel elements.The standard unit has a height of 1.5 m, a width of 1 m and a length of 1.65 to 2 m

To work needed:

• pipe cross-section 30x30 mm and a length of 1.5 m.
• pipe diameter of 15 mm;
• pipe 25x25 mm;
• edged board thickness of 40 mm;
• aluminum ladder;
• screws and bolts;
• Bulgarian;
• drill;
• welding machine;
• level.
  

  Metal homemade forest

Step 1. Preparation of spacers

From pipes with a diameter of 15 mm is cut into blanks for struts: horizontal length is 96 cm diagonal - 2 m Thereafter, the ends of two-meter tubes do.6 cm long incisions and flattened.This simplifies mounting spacers to the supporting pillars.

Step 2. Making adapters

need connectors for building forest - adapters.They are made of profile pipes: pipes 25x25 mm cut into pieces 30 cm in length, and of pipes 30x30 mm cut workpiece length of 8 cm Put on short and long billets are welded in the middle to prevent shifts..

Step 3. Assembling the frame

two uprights interconnected by horizontal struts privarivaya them every 30 cm. It turns the frame in the form of stairs.Similarly, the second frame is collected.The sheet metal plate is cut 70x70 mm square and they are welded to the lower ends of the flat struts.This section of the rack will not fall to the ground, even on the soft soil under the metal plate is placed an additional dense wood plank.

Step 4. Installation section

Two frame is placed vertically opposite one another and try on diagonal braces.Marker mark attachment points, then drilled in the racks and spacers bolt holes.Connect all the pieces together and check the level of the top horizontal bar.If the structure is skewed, have further customize all the elements, or stand on the forests will be difficult.

Step 5. Making flooring

boards for flooring can be laid in two ways - on the length and across the section.For the cross-deck structure on the sides bolted horizontal pipe at the level of the upper struts.To take longitudinal deck boards at least 2 m in length, the width of the knock section, reinforce the bottom of the trough cross bars.To

flooring is not shifted during operation, at its ends must be secured metal U-shaped profile of the thickness of the spacer.For this stack ready shield forests and the bottom line mark marker, where the horizontal strut touches the boards.Similarly, do the layout with the other end of the shield.Then take a profile of 17-20 mm wide, cut it to the width of the deck and fasten with screws to the boards on the marked lines.Now that the flooring will be laid on wood braces will be inside the profile, making it impossible to move the boards.

Step 5. Forest Painting

metal timber intended for repeated use, and therefore in need of protective treatment.Since forests are more often used for the exterior, from the damp frame covered with corrosion, especially in places of attachment.Therefore, after manufacturing and testing every element of forests should be sanded, wipe the dust, primed and painted.Wooden flooring is also treated with antiseptic and paint to protect from moisture and rotting.
