Description

The invention relates to the field of construction, in particular, to aluminum window profiles with internal insulation of “cold” glazing, protection against freezing and leaks, and finishing without changing the appearance of the building facade.

From the existing level of technology, a metal-plastic window structure is known, made for insulating glazed balconies and loggias and mounted close to an aluminum profile system to form a single structure. When creating this structure, the opening sashes on the aluminum profile system are first dismantled and metal corners are installed on the base of the balcony along the edge of the ceiling perpendicular to each static reinforcement of the aluminum profile system, one for each vertical profile of the metal-plastic window structures. Sealing material is attached to the vertical and horizontal profiles of the aluminum profile system. Next, between the static amplifiers of the aluminum profile system, metal-plastic window structures are mounted close to it with a gap between the static amplifier and the end of the metal-plastic window structure. The gaps are sealed and covered with platbands, after which a metal trim is mounted on the outside of the opening sash around the perimeter. [patent for invention RU 2708293 C1. IPC E04B 1/76, E04B 1/18, E06B 3/263. Application No. 2019106673 dated 03/06/2019, published: 12/05/2019 in Bulletin. No. 34]. The disadvantages of this technical solution include:

- lack of insulation and sealing of the floor slab and stiffeners, leaving cold bridges;

- when dismantling the doors of an aluminum structure, the opening parts of the new structure are pressed inside the room, which changes the appearance of the building, and also leaves the drainage channels that are in the aluminum structure open, which does not exclude leaks,

- after installation of the new structure, the aluminum structure is closed and monolithic, therefore, the possibility of its maintenance and repair is excluded.

Also known is the mullion-transom connection of filling elements of facade structures, which is used in the manufacture of facade structures based on the mullion-transom assembly of aluminum profiles with translucent filling elements in the “heat-cold” system. The connection contains load-bearing elements in the form of a post and crossbar, thermal insulation elements for connecting the filling elements - a thermal bridge and seals for the side surface of the filling elements. On the side of the less heat-intensive filling element, the connection contains two thermal bridges perpendicular to each other, combined into a rigid profile by means of metal profile elements, one of which is connected to the corresponding side surface of the rack or crossbar, and the second is configured to install a seal on the side surface of the less heat-intensive filling element on it [utility model patent RU 81753 U1. IPC E06B 3/00, E06B 3/30. Application No. 2008140894/22 dated 10/15/2008, published: 03/27/2009 in Bulletin. No. 9].

The disadvantage of the useful model is that this mullion-transom connection does not solve the problem of thermal shock of the glass of the abutment units (glazing and the colder wall adjacent to adjacent uninsulated loggias and balconies) in the window structure.

The closest to the proposed technical solution is a system for insulating mullion-transom glazing of balconies, which includes installing translucent glazing elements using seals in the corresponding grooves of the original mullion-transom aluminum profile, while the existing translucent glazing elements of the balcony in the form of glass are dismantled, the surface of the narrow part of the original aluminum profile is extended due to an additional mullion-transom profile, which has symmetrical grooves for installing a glazing bead on its side surfaces, as well as due to a thermal bridge, which is installed between the original and additional mullion-transom profiles, a glazing bead with a seal is installed in the corresponding grooves of the additional profile and in In the thus elongated mullion-transom profile, double-glazed windows are installed [invention patent RU 2658814 C1. IPC E04B 2/56, E04B 5/46, E06B 3/54. Application No. 2017119850 dated 06/06/2017, published: 06/22/2018 in Bulletin. No. 18].

The disadvantage of the invention is the lack of protection against leaks, freezing and thermal shock of the double-glazed window, which occurs due to the adjacency of junction points with different temperature conditions: a cold wall and insulated glazing.

The technical result of the proposed technical solution is to replace the cold glazing of an aluminum profile structure with a warm one, accompanied by protection against freezing and leaks from the upper floors.

The technical result is achieved by the fact that in an insulated aluminum mullion-transom profile structure, including double-glazed windows, tilt-and-turn plastic windows, aluminum frames, sashes, the following are provided:

an upper cut-off made of galvanized metal, encircling an aluminum post-transom profile structure and, on one side, fixed in sealing rubber above the upper double-glazed window, and on the other side, rolled, sealed and attached to the floor slab using dowels; sealed vapor barrier installation joint insulation, which consists of one layer of polystyrene foam, two layers of sealants and one layer of butyl tape, filling the spaces between double-glazed windows, sashes, aluminum frames, as well as the spaces between the floors of floors above the upper cut-off and in places adjacent to walls, floors and ceiling;

embedded fastenings, equipped with holes for fastening crossbars and imposts, installed in the fitting grooves of the racks and secured in them using thrust screws,

built-in crossbars and imposts with drainage holes, L-shaped cutouts on one side and overlays on the outside, adjacent to the racks and fixed with thrust screws through the corresponding holes on both sides in the fastenings.

The design uses a 60 mm thick double-glazed window, which can be tinted after installing an insulated aluminum mullion-transom profile structure. Crossbars and imposts are also painted in a color that matches the color of the frame.

Sealed vapor barrier installation joints and insulation are covered with pressure strips with decorative aluminum overlays.

The junctions of racks, mullions and crossbars are treated inside with polyurethane sealant for seams and joints, and outside with silicone, UV-resistant sealant.

According to fire safety rules, a metal cut-off is installed on the inside of aluminum façade glazing. It has only one fire-fighting function and does not protect against leaks from upper floors and freezing. When replacing cold glazing with warm glazing, an additional cut-off with a drainage function is installed in the proposed design, which allows you to protect this unit from freezing and from leaks from the upper floors and, thus, insulate the room.

When replacing cold glazing with warm glazing, it is often necessary to insulate the loggia itself indoors. For these purposes, it is necessary to have fasteners that allow you to obtain the necessary distance for attaching insulating materials. For such purposes, the invention implements a mechanism for additionally embedding imposts from the aluminum structure of the same name.

To ensure the correctness of the junction points along the perimeter of the glazing, install a crossbar or impost (door, window) of the same name used aluminum facade structure.

The inventive design is illustrated by the following figures (top view):

figure 1 - junction of an aluminum post-transom profile structure to the outer side wall before replacing the glazing;

figure 2 - junction of an insulated aluminum post-transom profile structure to the outer side wall;

figure 3 - unit for installing sashes into an aluminum mullion-transom profile structure (along the racks) before replacing the glazing;

figure 4 - unit for installing sashes into an insulated aluminum mullion-transom profile structure (along the racks);

figure 5 - unit for installing sashes into an aluminum mullion-transom profile structure (along the crossbars) before replacing the glazing;

figure 6 - unit for installing the sashes into an insulated aluminum mullion-transom profile structure (along the crossbars).

The figures show: 1 - ventilated facade with insulation, 2 - stand (profile), 3 - external seal, 4 - glass, 5 - wedge rubber, 6 - glazing bead, 7 - self-tapping screw, 8 - fasteners, 9 - junction, 10 - side wall, 11 - double-glazed window, 12 - clamping strip with decorative aluminum overlay, 13 - polystyrene foam, 14 - sashes, 15 - crossbar (profile), 16 - clamping strip seal, 17 - galvanized screw, 18 - tilt-and-turn plastic window, 19 - butyl tape. Implementation of the invention.

Before assembling the insulated ventilated facade with insulation 1, dismantle the installed glass 4 and sashes 14 without violating the integrity of the frame, remove the outer seal 3, glazing beads 6 and wedge rubber 5 around the perimeter.

Then polystyrene foam 13 is laid in the floor areas with foaming with mounting foam and sealing the seams, after which the lower cut-off (without drainage) is installed and sealed, which is attached to the floor slab with dowels and to the existing aluminum frame with galvanized self-tapping screws 7, while the joints are sealed with polyurethane seam sealant.

The installed upper cutoff, which performs the drainage function, is shown in Figure 7. During installation, the upper cutoff goes around the existing (not dismantled) aluminum frame. One side of the cut-off is sealed into the sealing rubber above the top double-glazed window to remove possible moisture from leakage from the upper floors to the outside of the building. The other side of the cutoff is rolled, secured to the floor slab using dowels, and the resulting joints are sealed with polyurethane joint sealant.

After this, the vacated openings are cleaned and processed and the drainage channels are cleaned, the existing crossbars 15 of the aluminum frame are strengthened with galvanized metal corners, at the bottom of the crossbar 15 on each side.

Installation of crossbars 15 and imposts to obtain the required distance for the purpose of general insulation of the internal space.

Installation of crossbars 15 or imposts consists of the following steps:

preliminary preparation, including selecting the fitting groove of the rack at a distance of 10-15 cm from the required location of the crossbar 15 or impost for fastening the fastenings, followed by inserting the fastening into the opened groove and fixing it there with stop screws; manufacturing a crossbar or impost blank, which consists of painting the crossbar or impost blank 15 in a color that matches the color of the frame,

trimming the crossbar 15 or impost to a size equal to the distance between the existing racks 2 or between the crossbars 15, taking into account a tolerance of 2-3 mm from the fitting grooves,

then cutting out the bead holding the sealing wedge rubber 5 from the outside of the crossbar 15 or impost,

making an L-type cutout on one side of the crossbar blank 15 or impost for inserting and connecting the blank to the fastening mortgage,

installation in the crossbar 15 or impost of a seal similar to that previously used in glazing,

creating drainage holes and holes for attaching the crossbar 15 or impost to the mortgage fastening with a standard screw connection,

removing residual chips;

installation of a crossbar or impost, including

insertion from the side opposite to the cutout L - type of workpiece for fastening,

checking the coincidence of the holes on the crossbar 15 or impost and the mounting fastening,

based on the results of the inspection, if necessary, modify the hole to ensure alignment of the holes,

then inserting the side with the cutout of the crossbar 15 or impost at the bottom under the diagonal into the glazing plane and placing it on the mortgage,

checking the location of the crossbar 15 or impost in the structure and the presence of distortions,

fixing the crossbar 15 or impost with screws on both sides,

treatment of the internal joints of the post-transom (or crossbar-transom, or side wall-impost) with polyurethane sealant for seams and joints, external places - with silicone, UV-resistant sealant.

Then, specially manufactured double-glazed windows 11 with a thickness of 60 mm and new tilt-and-turn plastic windows 18 are installed in the resulting window openings, the spaces between the double-glazed windows 11, sashes and cold aluminum frames, as well as the junctions 9 fixed to the side walls 10 are filled with an installation seam-insulation fasteners 8, floor and ceiling, carefully seal the insulating seams, cover them with butyl tape 19 and cover them with pressure strips with decorative aluminum overlays 12, painted in the color of the glazing or in any other color. The clamping strip seal 16 is placed under the clamping strip with decorative aluminum plate 12.

Vertical clamping strips have a size equal to the distance from the floor to the ceiling of the insulated room. The size of the horizontal clamping bars is equal to the distance between the vertical clamping bars.

Installation of clamping strips with decorative aluminum plates 12 is carried out on galvanized screws 17.

Cutting and installation of decorative ones is carried out vertically to the size with clamping strips with decorative aluminum overlays 12, horizontally, departing 18 mm from the width of the glass 4.
