What is the foundation of the FBD blocks for light structures and how to build a 1 day

Preparatory stage

The preparatory phase is not taken into account in terms of the actual construction of the foundation, because it depends on productivity, wage-workers, or navvies excavator, recruitment is significantly increases the cost of cost of work.

The essence of the preparatory phase - digging trenches for device sandy-gravel cushion, which, in consequence, the blocks are stacked FBS. The depth of the trench depends on the depth of soil freezing construction in the region. In this example, it was 0.8 meters (Region: South of West Siberia). 500 mm - building sand, 200 mm - gravel fractions 70-120, 100 mm - rasklintsovka gravel fractions 20-50.

cushion device prevents swelling due to uneven foundation frost topsoil. Pay particular attention should be taken to the device "cushion" in areas with high occurrence of soil water.

Stacking blocks PBS

For the construction of the foundation blocks used FBS and FBS 9-3-6 06/03/24. Laid directly from the body of the car with the help of a manipulator. Adjustment of the place was done by hand. After laying the horizontal level of each block tested l-1 m.

Check horizontality FBS

The spatial orientation of the blocks relative to each other controlled laser level.

IMPORTANT!

The width of the trench should be 100 mm larger than the width of blocksFBS(300 mm) to permit the adjustment in accordance with the size of the future framework.

The gaps between the slopes of the trench is filled with gravel and blocks 20-50 with subsequent segment rammer timber l - 1000 mm.

Mounting tabs bent on blocks hammer or an ax.

Strapping apparatus for log

Tying log was made from pine timber 200x200 mm. To bind the corners at the ends of the boards was chosen fourth. It took a minimum of tools:

• Circular electric saw;
• Hacksaw on a tree (to adjust);
• Joiner's Corner;
• Construction roulette;
• Ax and Hammer (1000 gr.).

Before laying and fixing the beams tying them is recommended to treat with antiseptic. He proved to be excellent antiseptic "Pinotex". In addition to protection against moisture and mold growth, it allows you to tint the wood, enhancing the natural texture, it does not require additional treatment varnish.

On the upper edge of foundation blocks 1-2 plank waterproofing layer from "flashing". For a snug fit to the surface of the FBS it can be treated with a blowtorch.

To avoid bias trim during assembly and articulation angles log space bar segments along the long side of the foundation (6,000 mm) were joined by metal staples. In piping, unlike mauerlat no load acts arching of trusses, so fastening the blocks PBS be neglected.

Construction of the foundation of the FBS - a simple and fast way, ideal for pools, outbuildings, one-storey buildings a small area.
