Abstract

FIELD: construction.

SUBSTANCE: insulated ribbed panel comprises bearing longitudinal ribs made of wood, cross ribs of wood, double-sided paneling of sheet material, heat insulation material. Bearing longitudinal ribs are made with Z-shaped section with flat veneer wall and wood belts, which are rigidly fixed to wall on different sides, and cross ribs are made of two separate layers of wood. Heat insulation material is laid onto internal paneling and on wood of adjacent longitudinal rib belts and between layers of cross ribs.

EFFECT: increased heat insulation properties of panel without increase in its thickness.

Description

The invention relates to construction and can be used in all areas where its analogues are used, for example, for the construction of coatings or external walls of buildings.

Closest to the proposed solution are solutions of ribbed slabs of box-shaped section (Gappoev M.M., Guskov I.M., Ermolenko L.K. et al. Structures made of wood and plastic. M .: Publishing house ASV, 2004, p.174 -175). The panels include load-bearing longitudinal ribs made of wood, transverse ribs made of wood and double-sided cladding of sheet material (plywood, asbestos cement, etc.). As a heater, fireproof, biologically resistant heat-insulating materials of various densities and efficiencies are used. Such panels are used for the construction of buildings in various climatic conditions, including those with extremely low outdoor temperatures. At low temperatures, to ensure the required resistance to heat transfer, highly effective heat-insulating materials with a low coefficient of thermal conductivity are used. In such cases, wooden ribs are the “bridge of the cold”, the more noticeable, the more effective the thermal insulation material. In this regard, the thickness of the ribs may increase in order to provide the required heat transfer resistance, although such an increase in size is not required to solve the problems of ensuring strength and stiffness.

The objective of the invention is to improve the insulating properties of the panel without increasing its thickness.

This is achieved by the fact that the longitudinal edges of the panel are made of a Z-shape with a flat plywood wall and wood belts, rigidly attached to the wall. The heat-insulating material is laid on the inner lining and on the wood of the belt adjacent to it, thereby achieving breaking the “cold bridge” in the wood. The heat-insulating material laid on the lining and on the wood of the belt of the longitudinal ribs may be the same or (option) the material on the wood may have a lower coefficient of thermal conductivity than the material on the lining. The transverse ribs installed in the area of the joints of the casing contain two separate layers of wood, between which is a layer of heat-insulating material.

Figure 1 shows a diagram of a cross section of a panel. The panel comprises an inner 1 and an outer 2 sheathing of sheet material, attached to the bearing longitudinal ribs. The longitudinal ribs contain wood belts 3, rigidly attached to the plywood walls 4, and the belts adjacent to the inner skin 1 are attached on one side of the walls 4, and the belts adjacent to the outer skin, on the other, forming Z-shaped sections. Heat-insulating material 5 is laid on the inner lining 1 and on adjacent to it belt 3 of the longitudinal ribs.

Figure 2 shows a diagram of the cross section of the panel (option) with two types of heat-insulating materials. The heat-insulating material 5 is laid only on the inner lining 1, and heat-insulating material 6 with a lower coefficient of thermal conductivity is laid on the adjacent belts 3 of the longitudinal ribs.

Figure 3 shows a part of a sectional diagram of a panel in a plane parallel to the walls of 4 longitudinal ribs. The layers 7 of the transverse ribs made of wood are installed on the skin 1 and 2 in the zones of their joints. Between layers 7 laid thermal insulation material 5.

The proposed insulated ribbed panel allows you to improve the heat-insulating properties of fences (wall or cover) without increasing their thickness: increase heat transfer resistance and reduce the risk of freezing in areas of longitudinal and transverse ribs.
