Abstract

FIELD: construction engineering. SUBSTANCE: outer layer of wall of framed building is built flush with end face of floor slab. Made in body of slab in wall supporting zone parallel to its outer end face are through-slots filled with thermal-insulating material. Width of slots is less than total thickness of multilayer wall. Thickness of thermal insulation is larger than length of abutments. Installed in inner layer discretely over length of wall are vertical wooden props. Surface of props facing inside premise is sunk in relation to surface of inner layer and is protected with building mortar. Used as heat conserving material is foampolystyrene or mineral wool board or foampolymergypsum board or foamkapron. Installed in through-slots of floor slabs and in middle layer of wall are foampolystyrene boards separated from each other in height by mineral wool boards. Installed at places of wall openings in end faces of abutments between abutment and inner layer of wall are wooden bars protected at side of wall opening by coating of building mortar. Used as inner layer are gypsum partition boards joined by groove and tongue or cement-sand blocks. EFFECT: higher efficiency. 6 cl, 1 dwg

Description

 The invention relates to the construction and can be used in the construction of buildings with self-supporting walls within the floor.

 To fill the openings of the outer walls of frame buildings, it is known to use panel elements of a multilayer structure, in which panels are hung on the transverse supporting structure of the frame and columns [1].

 Also known is the supporting panel of the building, installed between the columns of the frame of this building, made multilayer. The panel is attached to the steel columns of the building frame. Each panel contains a heat-insulating layer of foamed phenol, the outer and inner layers [2].

 The closest analogue to be taken as a prototype of the invention is the construction of a frame building containing floor slabs and multilayer outer walls in the form of an outer layer of small pieces, preferably half-brick thick with buttresses protruding inside the wall, thermal insulation of the middle layer of the wall and inner layer [ 3].

 A disadvantage of the known structures is poor thermal insulation of horizontal joints of walls with ceilings, and if, when performing external walls in the form of panels, they are mounted on a building frame, which allows isolating the frame elements from outside air, then in the case of making a wall of piece materials (for example, brick ) such insulation is not reliable enough.

 The objective of the invention is to increase the thermal insulation of a frame building with multilayer walls with an outer layer of small pieces and the use of self-supporting within the floor of the outer walls.

 This problem is solved in that the frame building contains floor slabs and multilayer outer walls in the form of an outer layer of small pieces, preferably half a brick thick with buttresses protruding into the wall, thermal insulation of the middle wall layer and the inner layer. The outer layer of the wall is mounted flush with the end of the floor slab, in the body of which through the grooves parallel to its outer edge formed through grooves filled with insulating material, having a width less than the total thickness of the multilayer wall. The thickness of the thermal insulation exceeds the length of the protrusions of the buttresses. In the inner layer of the wall, vertical wooden posts are discretely mounted along its length, the surface of which, facing the inside of the room, is recessed with respect to the surface and protected by a mortar. As thermal insulation can be used polystyrene foam or mineral wool board, or foam-gypsum board, or foam cap. In the through slots of the floor slab and in the middle layer of the wall, polystyrene plates are installed, separated from each other in height by mineral wool plates. In the places of organization of window and door openings in the wall on the ends of buttresses, wooden bars are installed between the buttress and the inner layer of the wall, protected from the opening by grout from mortar. In addition, grooved-crest partition plates or cement-sand blocks are mounted as the inner layer.

 The drawing shows a General view of the frame building.

 On columns 1, floor slabs 2 are mounted cantileverly projecting towards the outer wall 3. The outer wall is multilayered: the outer layer is made of small pieces, preferably half brick brick 4 with buttresses acting discretely along the front of the wall inside the wall 5. A layer of thermal insulation is laid between the buttresses 6 , which can be formed by polystyrene foam, mineral wool board, gypsum foam boards, foam cartridge or other heat-insulating material that meets the requirements of sanitation, heating technician , Fire safety, etc. The inner layer 7 is installed "on the fly" relative to the ends 8 of the buttresses. This layer can be formed by gypsum groove-crest partition plates or cement-sand blocks. The outer layer of the wall is mounted flush with the end face 9 of the floor slab, in the body of which in the zone of support of the wall parallel to its outer edge, through grooves 10 are formed, filled with heat-insulating material, for example, polystyrene foam. The width of the grooves is less than the total thickness of the multilayer wall. The thickness of the insulating layer exceeds the length of the protrusions of the buttresses. To prevent the spread of fire in case of fire through the heat-insulating layer between the polystyrene foam 6 of the wall insulation and the polystyrene foam filling the through grooves 10, a gasket 11 made of mineral wool is installed. In the places of organization of window and door openings, buttresses 12 are also formed in the wall, on which wooden beams 13 are installed between the buttress and the inner layer of the wall, protected from the side of the opening by mortar 14. To give the inner layer of the wall additional stability, it can be discrete along the length of the wall mounted vertical wooden racks 15, the surface of which, facing the inside of the room, recessed with respect to the surface of the inner layer and protected by mortar 16.
