Abstract

FIELD: civil engineering, wall fencing of buildings of industrial and civilian assignment. SUBSTANCE: construction panel includes wooden frame, outer facing and inner sheathing attached to it, layer of foam plastic and flat diaphragm placed inside panel. Flat diaphragm comes in the form of bearing bonded wooden board 40-50 mm thick and is placed at distance of 0.25-0.55 thickness of panel from sheathing. Panel is fitted in addition with layer of heat insulation made of mineral material with thermal conductivity under 0.15 W/m C installed between sheathing and flat diaphragm, layer of foam plastic located between outer facing and flat diaphragm. Foam concrete containing, per cent by mass: mineral binder 21.0-71.0; sand of natural or artificial origin 15.0-40.0; foam agent 1.3-7.4; water being the balance is utilized in the capacity of mineral material. Foam glass and mineral wool can also be utilized as mineral material. Flat diaphragm is made of structural wood shavings material or plywood. Phenol foam plastic or foam resol resin or foam polyurethane can be used in the capacity foam plastic. EFFECT: increased heat insulation properties, reduced cost of panel with preservation of sufficient fire resistance and bearing capacity. 6 cl, 1 dwg

Description

 The invention relates to the construction and is intended for wall fencing of industrial and civil buildings.
 A multilayer building panel for building walls is known, including a wooden frame, vertical posts attached to it, cladding elements, between which insulating concrete is poured. A layer of insulating polystyrene with gypsum sheathing is attached to the inner surface of the panel. Between the layer of concrete and insulating polystyrene there is an air gap (see FR 2629504 A1, IPC 7 E 04 C 2/26, publ. 06.10.1989).
 The closest analogue to the proposed invention is a building panel, including a wooden frame, the outer lining, the inner metal profiled sheathing, the middle layer of foam and a flat diaphragm located on the inner side of the sheathing (see SU 885489 A, IPC. E 04 C 2/26 , publ. 11/30/1981).
 The disadvantages of this panel are low thermal properties and high cost due to the use of metal profiled sheathing.
 The objective of the invention is to increase the thermal properties and reduce the cost of the building panel while maintaining its sufficient fire resistance and bearing capacity.
The problem is solved in that in a building panel, including a wooden frame, an external cladding and an inner lining attached to it, a foam layer and a flat diaphragm located inside the panel, the flat diaphragm is made in the form of a bearing glued wooden board 40-50 mm thick and placed on a distance from the casing equal to 0.25-0.55 of the panel thickness, while the panel is additionally equipped with a thermal insulation layer of mineral material having a thermal conductivity of not more than 0.15 W / m o C, installed between the casing and the flat aphragma, and a foam layer is placed between the outer lining and the flat diaphragm.
Moreover, as a mineral material, foam concrete is used, obtained from the composition in wt.%:
Mineral astringent - 21-71
Sand of natural or artificial origin - 15-40
Frother - 1.3-7.4
Water - Else
Also, foam glass or mineral wool is used as the mineral material.
 In this case, the flat diaphragm is made of structural wood-particle material or plywood, and the phenolic foam FRP-1, or Penorezol-NT, or polyurethane foam is used as the foam.
 Penresol-NT phenolic foam based on phenol-formaldehyde resin is protected by patent RU 2140949.
 The load-bearing glued wooden shield made of vertically arranged bars works as a centrally compressed element, providing an even distribution of the load throughout the building frame. On the other hand, a glued wooden board, being in the thickness of thermal insulation, is less exposed to temperature and humidity stresses, which can lead to delamination of the adhesive joint. The use of an adhesive wooden board reduces the cost of the panel, as a whole increases the bearing capacity of the building frame, and additional thermal insulation made of mineral material increases the heat-shielding qualities of the structure. Relatively cheap fire-resistant materials, such as drywall, are used as inner lining. The ratio of the thicknesses of the foam layers and additional thermal insulation is determined by thermal engineering calculation, the results of which allow you to place a flat diaphragm at the required level, equal to 0.25-0.55 thickness of the panel.
The drawing shows a construction panel in section. The panel includes an inner lining 1, an outer lining 2, foam 3, a flat diaphragm in the form of a glued wooden shield 4, thermal insulation from mineral material 5 and a wooden frame 6. The panel is made as follows. The panel shell is pre-mounted - the inner lining 1, the outer lining 2 and the flat diaphragm 4 and are attached to the wooden frame 6. The formed cavity between the outer lining and the flat diaphragm is filled with urea-formaldehyde foam, and the cavity between the inner lining and the flat diaphragm is filled with non-heat-resistant heat-insulating foam insulation 0.12 W / m o With a bulk density of 450 kg / m 3 . Foam concrete is obtained from a foam mixture containing in wt. %: mineral binder - Portland cement - 52, expanded perlite sand fraction up to 2.5 mm - 35, foaming agent - saponified wood resin - 2.5 water 10.5. After curing the foam and foam concrete panel is ready for use.
 The use of the building panel according to the invention provides an increase in thermal properties and a reduction in the cost of the building panel while maintaining its sufficient fire resistance and load-bearing capacity.
