Definitions

  • the invention relates to construction, namely to methods of erecting multilayer exterior walls of residential, public and industrial buildings.
  • Known multilayer cast-in-place wall comprises outer and inner layers of non-removable formwork, which are connected by rod bracings and/or load-bearing framework, between which a monolithic layer of heat- insulating filler is placed.
  • the outer layer of the non-removable formwork is made of tiles, while the rod bracings and/or load-bearing framework are fitted up with external bearing elements made of metal profiles to which tiles of the outer layer are attached.
  • Tiles of the outer layer are made of one of the following materials: ceramics, ceramic granite, fiber cement, concrete. Profiles for outer bearing elements are made in the form of an 1- beam or a channel. Polystyrene concrete or foam concrete is used as a heat-insulating filler of a monolithic layer (utility model patent RU 30148, IPC E04B2/00, published on 20.06.2003).
  • the closest to the declared solution is the method of erecting an exterior multilayer wall of a building, which includes a floor-by-floor installation of outer layer of prefabricated panels, fixing these panels to the bearing structure of the building with metallic bonds, sequential mounting of the intermediate heat-insulating layer from inside the building, thus forming a ventilated air gap and inner layer.
  • the prefabricated light decorative outer panel is fixed from inside the building by means of "G-shaped" brackets and bolts to a pre-made floor-by-floor metal load-bearing framework, after which the intermediate heat-insulating layer is installed by attaching it to a metal mesh fixed to the inner side of the facing (patent for invention RU 2335606, IPC E04B2/88, published on 10.10.2008).
  • the object of the invention is to simplify the method of erecting a wall, increase the sound-proofing and thermal-insulating properties, water resistance, fire and seismic safety, frost resistance and reduce the weight of the erected wall.
  • the essence of the invention is a method of erecting an exterior multilayer wall of a building, which includes mounting of a metal frame, installing an outer layer of facing elements, sequential mounting from inside the building of an intermediate insulating layer and an inner layer.
  • a metal frame when mounting the metal frame from outside the building profiles are fixed to the end of the concrete floor decks with a gap, forming an outer metal frame in the form of a light metal thin-walled structure.
  • Inner metal frame is formed through fixing profiles to concrete floor decks.
  • the facing elements are set up so that a gap remains between the inner surface of the facing elements and the outer surface of the profile of the outer frame.
  • a layer of polyurethane foam is sprayed under pressure onto the inner surface of the feeing elements until the cavities between the polyurethane foam layer and the back side of the facing elements disappear. Polyurethane foam is then added layer by layer until the space between the facing elements and inner frame is filled.
  • sheet elements of internal use are fixed to the inner frame.
  • Figure 1 shows the face side of the exterior wall erected by the proposed method, while Figure 2 depicts section A-A shown on the Figure 1.
  • Figure 3 is a close-up picture of the attachment point of the channel to the concrete floor deck from the front, highlighted in Figure 1 by a dashed ellipse.
  • Figure 4 shows section B-B in Figure 1. and Figure 5 is section C-C of Figure 3 after all four stages of installation.
  • the mounting of the outer metal frame was made by means of cold formed, thin-walled galvanized U-shaped channels ( 1 ) of 93x53x2 mm in size.
  • the gap (5) between the concrete floor (2) and the channel ( 1 ) compensates for the construction inaccuracies in the concrete frame of the building, and also helps to reduce the cold joints, thus leading to an increase in thermal insulation.
  • Channels ( 1 ) are fixed at a pitch of 400-600 mm.
  • Mounting of the internal metal frame is carried out according to Knauf standards. Cold formed thin-walled galvanized profiles (7) of 50x50x0.6 mm have been used for this purpose, which are fixed on the surface of floors according to Knauf standard with a pitch of 400-600 mm.
  • the gap between the outer and inner metal frame is 200 mm.
  • the facing elements (8) are fastened to the corners (9) fixed to U- shaped channels ( 1 ) in such a way that a gap (10) of 10 mm is left between the inner surface of the facing (8) and outer surface of U-shaped channel ( 1 ) to reduce the cold joints.
  • a layer of polyurethane foam ( 14) is sprayed under pressure onto the inner surface of the facing (8) until there are no free cavities between the polyurethane foam layer ( 14) and the back side of the facing (8).
  • Polyurethane foam is then added layer by layer until the space between the facing and the inner metal frame is completely filled.
  • the width of this space is 200 mm, and the polyurethane foam is sprayed under a pressure of 150 atm.
  • Polyurethane foam is applied layer by layer, giving each successive layer approximately 20 seconds to "set".
  • the inner layer is installed in the form of 10 mm thick fiber cement sheets ( 15) in accordance with Knauf standard.
  • an intermediate layer is usually formed after the inner layer has been assembled, i.e. in fact we get a non-removable formwork.
  • origination of free cavities between the intermediate layer and the outer facing layer is inevitable, and it leads to moisture penetration.
  • Spraying of polyurethane foam under high pressure prior to installation of the inner layer allows to completely eliminate the origination of such cavities.
  • the proposed method of erecting an exterior wall is applicable for any structural schemes of the load-bearing frame of a building (reinforced concrete, metal, wood, etc.).
  • the technical effect of the proposed invention manifests itself both in the method of erecting a wall, and in a number of advantages of the wall itself.
  • the method is cost-effective and does not require much time for wall mounting, since lightweight galvanized metal studs and dry installation are used (there are no wet processes).
  • the entire process of wall erection is carried out from inside, there is no need for scaffolding from outside of the building, which significantly raises the efficiency of this method.
  • the resulting three-layered wall has low weight, high thermal-insulating and sound-proofing properties, fire safety, frost resistance and a long service life (over 35 years).
  • Water resistance is significantly increased due to the absence of free cavities between the layer of polyurethane foam and the back side of the facing.
  • the level of seismic safety is also essentially increased because of the lightness and flexibility of the structure and elasticity of the polyurethane, as well as due to the fact that, in case of facing destruction, pieces of the destroyed facing plates do not fall to the ground, but remain glued to the wall due to very high adhesion of the polyurethane.

Abstract

Selon le procédé de l'invention, lors du montage du cadre métallique (1) depuis l'extérieur du bâtiment, des profilés sont fixés à l'extrémité des dalles de plancher en béton (2) avec un espace (5), de sorte à former un cadre métallique externe (1) en forme de structure métallique légère à parois minces. Un cadre métallique interne (7) est formé en fixant des profilés à des dalles de plancher en béton (2). Lors de l'installation de la couche externe, les éléments de parement (8) sont configurés de sorte à conserver un espace (5) entre la surface interne des éléments de parement (8) et la surface externe du profilé du cadre externe (1). Lors de l'installation de la couche d'isolation intermédiaire, une couche de mousse de polyuréthane (14) est pulvérisée sous pression sur la surface interne des éléments de parement (8) jusqu'à ce que les cavités entre la couche de mousse de polyuréthane (14) et le côté arrière des éléments de parement (8) disparaissent. De la mousse de polyuréthane (14) est ensuite ajoutée couche par couche jusqu'à ce que l'espace entre les éléments de parement (8) et le cadre interne (7) soit rempli. Lors de l'installation de la couche interne, des éléments en forme de feuille (15) pour une utilisation interne sont fixés au cadre interne. Le procédé d'érection d'un mur est simplifié, le poids du mur est réduit, et les caractéristiques de performance du mur sont améliorées.
