The invention relates to the field of building structures, in particular to the field of wooden structures and may find application in the design and manufacture of load-bearing structures of different types.

The claimed invention is directed to solving problems, which consists in increasing the bearing capacity and fire resistance of load-bearing wooden structures, as well as protect them from damage and aging.

A known number of kledering structures reinforced with various materials, in particular steel and non-metallic fittings (see, for example, Cai T.N., Borodzicz, M.K. and other “building Construction”. Tutorial in 2 volumes, V. 1 M, stroiizdat, 1977., Grin IM “Building structures of wood and plastics. Design and calculation”. Kyiv. “High school”, 1975.

One disadvantage of such constructions is significantly lower than the limit of fire resistance in comparison with solid wood and claudelalanne designs, due to the fact that with increasing temperature the heating of the valve leads to charring wood in the contact zone and the violation of the joint work of wood and fittings, which leads, in turn, to premature structural failure. In the invention, metal or any fittings not used.

From the literature (in particular “Design of dereva plastics: textbook for universities.” Ed. Gay and Yevsikova, 5th edition, M., stroiizdat, 1986.) known property of wood not to raise the temperature above 100°to evaporation of all moisture.

The technical result of the invention is the improvement of fire resistance and bearing capacity of wooden elements and structures.

This technical result in the implementation of the invention is achieved by the fact that the wooden element with a high resistance, including wooden blocks drilled with horizontal and vertical holes, the pipe for the fluid and electric characterized in that the holes in the bars are connected vertically and horizontally, with the Central horizontal hole drilled along the length of the element and muted at the edges, and the vertical holes through.

Wooden element with a high resistance contains wooden beam 1 (1a to the top of the crown and 1B for others), the pipe adapter to supply water to the structure 2, electric 3 connected to the fire alarm sensors. Structurally differ only bars that will be used for the upper crown of the building. They have a vertical hole with one hand muted, and the horizontal holes through. In normal conditions the holes empty, not full. With increasing temperature and about what adowanie smoke (which is typical for fire conditions) trigger temperature and smoke sensors and fire alarm systems. When a signal is sent to the remote fire at the same time the signal on electric, which provides access water from the main water system inside the structure. Acting under pressure, the water fills the design until, until you reach the top at the crown of the building. Reaching the top of the crown of the building is filled, the excess water begins to grazed through the through holes that circulates the water, and therefore its cooling. The fluid from the holes due to capillary suction enters the area exposed to heat. To increase the speed of filling the structure with water on each wall of the building, water is supplied separately.

This system can also be used to protect the wood from damage, periodically filling the system with antiseptic solutions.

The invention is illustrated graphics, which depicts a longitudinal section of the proposed design.

Wooden element with a high resistance, including wooden blocks drilled with horizontal and vertical holes, the pipe for the fluid and electric, characterized in that the holes in the bars are connected vertically and horizontally, with the Central horizontal hole drilled along the length of the element and plugged the and edges, and vertical holes through.

SUBSTANCE: invention refers to the sphere of construction technologies and immediately deals with glued wooden structures. The suggested method of pre-tension of glued wooden packages in the across-grain direction presupposes their compression with the help of steel rods. The element of novelty consists in applying to the wooden package being forced together a pressure of 0.5 MPa with the help of steel rods gummed down inside the pre-drilled holes arranged along the whole of the package length (the spacing being equal to 300-500 mm.). The length of the rods is equal to the package width with due allowance for its eventual reduction after application of force-together pressure.

EFFECT: minimisation of material and labour expenditures related to pre-tension of glued wooden packages in the across-grain direction without distortion of their overall dimensions.
