Construction

Basis – sloping rafters of wood. It’s legs are placed along the slope of a mauerlat, that is a wooden pad, attached to the walls. The upper ends of rafters rest on the beam-run, which relies on a system of racks. The stability of truss system is provided by braces, struts and diagonal ties, held together in a single structure. It is fixed by the wind. Rafters fixed twist of wire, galvanized better that are tied to the pins, bound into the stone walls. In the rafters of the wooden houses are connected to the second upper crown of the log-bar.

For ease of use roof-roof the lower ends of the feet are placed on the rafters mauerlat distance of 35-40 cm from the ceiling. Between masonry and paving mauerlatom two layers of roofing material.

Roof eaves may be formed through the issuance of rafters for the exterior wall or lengthening them with wooden “locusts” of the boards on the nails. On overhangs or “bridge” perform continuous sheathing of planed 25-mm plates. Plating performed on sections of a slope and in valleys.

Hanging truss systems can be applied in buildings where it is necessary to block a substantial span without support. I should say that hanging the system when installing them, require that a crane (crane or other). We demonstrate high-efficiency wood constructions, beams, rafters and trusses of the German company “Wolf”, they are described below.

Elements of wood for rafters, beams – solid wood and saving. As everyone knows, the tree in the butt of much broader than in the crown. The German company “Wolf” took into account the nature of this phenomenon for more rational consumption of wood materials. The company estimates that if the boards carry out the tree, the losses are to sections of timber to make the proportional sides about 60%. Taking into account that, they began to prepare the bars of a rational section, taking into account the thinning of the tree. And composing them, knocking in 2 and 3 wood beams with special pads, get a solid rafter, run-beam work better in design. Compound bars and plates of the “Wolf”, fasten 2.3 bar in the design. It turns out saving timber, transportation, media. Lining of steel, forged from a single sheet under pressure. It turns out the plate with 2-3 rows of pins, which are strengthened, and their driving in from both sides of the beam rafters. The design of robust, reliable connection (galvanized steel). In addition, the rafters should be read in “carpentry-joinery.”

Attic with sloping windows

In many countries around the world in cities, suburbs and rural areas began to be used for residential purposes attics, storage, office. This type of attic with slanted windows and insulated roof allows efficient use of the attic. This innovation was initiated builders of Denmark, and is now widely used in many other countries around the world. In our country, including in St. Petersburg, lofts began to turn in the attic with slanted windows. This type of two-storey house is made of JSC “DASK” on the embankment of the river Buckles.

Use attic holiday home accommodation with the execution of a sloping windows is very useful.
