Description

The utility model relates to construction, namely, to the construction of the facade of a monolithic-frame building.

When decorating the front surface of building facades, hinged facades with a ventilated air gap (hereinafter referred to as IAF) were widely used, which made it possible to fasten IAF only at the ends of floors (RU 69114). A disadvantage of the known solutions is the need to carry out significant amounts of finishing work from the outside of the facade, using scaffolding or lifting platforms, as well as the great labor costs associated with the installation of masonry walls.

Known (RU 102646) is a wall panel comprising a sandwich panel, characterized in that it is provided with supporting elements fixed to the sandwich panel in such a way that they protrude beyond the end face of the sandwich panel, and facade panels mounted on the supporting elements and a supporting bracket containing a supporting element made with the possibility of fixing on the floor, a vertical slider with a support platform, connected with the support element with the ability to move in the vertical direction, fixation on the support element and installation at its reference site sandwich panel situated above the wall panel and the horizontal slide, associated with the support member movably in the horizontal direction, fixing on the support member and fixed on the projecting portion of each support element of the wall panel.

Known panel wall mounted frame (RU 161942), containing a supporting frame made in the form of a collapsible frame, assembled from perforated metal profiles, outer and inner sheet cladding, and heat insulation placed inside the panel made of heat and sound insulation material, and the frame is made quadrangular forms, two opposite sides are made of profiles of a U-shaped section, and the other two sides are made of profiles of a C-shaped section, the profiles forming the frame of the panel are rigidly connected between an attachment element between a covering sheet and a heater disposed steam and / or waterproofing material between the sheeting and the frame is placed paroshumopoglaschayuschaya tape and / or film, characterized in that the supporting frame further comprises a lock connection and the metal brackets welded; at the same time, the locking connection is assembled from docking elements between which thermal insulation material is laid; at the same time, a sealing tape is placed around the perimeter of the connecting elements; wherein the bracket contains a fixed plate with holes for mounting to the beam (overlap) and a plate intended for fastening to it rack-mount profiles of the steel frame of the panel; wherein the bracket has a support plate for securing the overlying panel using self-tapping screws; wherein the bracket comprises a vertical stiffener and a horizontal stiffener to reinforce the structure.

The disadvantage of these solutions is the need for the manufacture of technically complex load-bearing brackets and large wall panels, their transportation to the place of installation, the use of heavy mechanization to unload and install panels and perform expansion and heat-shrink seams from the inside of the finish with a step limited by the maximum panel length and strict binding of the facing plates to the dimensions of wall panels and the implementation of the bearing base (building frame) with high accuracy. In addition, when using these panels, it is not possible to perform enclosing structures of a radiused shape, cantilevered vertical flights and the formation of window openings whose dimensions exceed the dimensions of the panel or have a complex shape, and spot freezing is possible on the supporting brackets, which reduces their corrosion resistance and term service.

There is a method of erecting a multi-layer wall of a building (RU 2282697), when the outer panel is hung over the entire facade of the building with hooks on the eyes installed on the supporting structures of the building, then the inner wall is erected from lightweight masonry using small pieces and fill the space between inner and outer walls with insulation. In this case, the panel is equipped with four fastening elements in the form of mounting hooks.

There is a method of erecting the outer wall of a building (RU 2495203), which includes installing the outer and inner walls separated by an air gap and placing insulation between them, first, complex facade panels are hung on the building frame, and after installation of the complex facade panel, the gaps between the insulation boards are filled with insulation and the second layer of insulation is attached to the heat-insulating layer of complex facade plates.

The main disadvantage of these solutions is the need for precise cutting of holes in the insulation for mounting hooks and consoles, which is quite laborious to carry out, given that the work is carried out directly during the construction of the wall using most often improvised means. In addition, the low quality of the thermal insulation device due to the lack of vapor barrier and the low corrosion resistance of the panel mounts can also be considered disadvantages.

Closest to the claimed utility model in technical essence and selected as a prototype are technical solutions for patents RU 153834 and RU 2591315.

The wall fence of the building (RU 153834) consists of hinged frame panels, includes a mounting unit, which is a metal mounting plate made with the possibility of fastening to the floors of the building, with a metal guide element, as well as wall mounted panels made with an embedded embedded part, representing a plate with two threaded bushings, due to which the top of the panel is secured to the mounting plate using bolts, as well as with a mounting hole with on the side of the bottom of the panel, through which the wall panel is mounted on the guide element of the mounting plate, centered with a conical washer and nut, adjustable in a horizontal plane and fixed at the required level, as well as the Method of fastening the wall fence (RU 2591315), consisting of hinged frame panels , consists in the fact that the frame panels are mounted on the floors of the building by means of mounting plates with a metal guide element, so that the upper panel is mounted on a metal guide element t of the mounting plate of the bottom panel through the hole previously cut into the panel frame, fastening the upper part of the panel to the ceiling with fixing plates, adjusting the height of the panel using a system of a centering washer and nut installed on the guide element of the mounting plate, and bolts securing the panel to fixing plates, fix the position of the upper panel, then the gap formed between the upper and lower panels is filled with insulation, and then steam is mounted from the inside zolyatsionnuyu finishing film and sheets, and externally mounted decorative ventilated façade comprising guide elements and decorative facade facing sheets.

The disadvantages of the prototype are not high enough performance and thermal performance of the elements of the panel, namely:

- the need for factory manufacturing of wall panels and their transportation to the installation site,

- the need to use heavy mechanization for unloading and installing panels in connection with the large size of the panels and their weight,

- the need to perform expansion and heat-shrink seams from the inside of the finish with a step limited by the maximum panel length,

- a high probability of point freezing on the profiles of the frame and a decrease in their corrosion resistance and service life,

- the need for strict binding of facing plates to the dimensions of wall panels,

- the lack of the ability to perform enclosing structures of radius shape (in plan),

- the inability to control the filling density of the insulation inside the panel when accepting the result of installation work (on site),

- low corrosion resistance of the frame of the panels in conditions of use in medium and highly aggressive environments.

The objective of the proposed utility model is to increase the operational characteristics of building envelopes of buildings and structures based on light steel thin-walled structures (LSTK), as well as the manufacturability of their installation.

The technical result consists in improving thermal performance, increasing corrosion resistance and durability of the structure, reducing internal stresses in the frame racks associated with the temperature difference on the external and internal surfaces of the rack, increasing the fire resistance of structures, the ability to perform architectural forms of any complexity, performing facade cladding without reference to the dimensions of wall panels, the possibility of performing the inner surface of the wall without expansion joints and improving manufacturability works.

The technical result is achieved due to the fact that the device of the facade of a monolithic-frame building is proposed, including metal fasteners with metal guides attached to them and installed behind them and fixed to the building base of the building through embedded parts with an anti-corrosion coating the outer edge of the building base thermally stripped rack-mounted metal profiles, and the inner space of the profiles and space The distance between the rack profiles is filled with a heater installed with overlapping horizontal joints, on the outside, Z-shaped profiles of the horizontal battens with an additional layer of insulation and a wind-moisture-proof membrane installed with overlap from the previous layer and a facade profile with facade panels fixed to it, are attached to the rack profiles. and from the inside to the rack profiles through the vapor barrier film the elements of the interior decoration of the wall panel of the building are attached.

The proposed arrangement of the facade, consisting of individual parts (mounting plates, profiles, insulation plates, facade plates, interior decoration plates of wall panels), allows the installation of the building envelope directly at the construction site. The racks of the frame of the building envelope are attached to reinforced concrete slabs or metal beams of the building base. Filling the internal cavity of the rack profiles and the space between the profiles, the individual insulation layers installed with overlapping horizontal joints eliminates the possibility of voids and blowing. The installation of an additional heat-insulating layer in horizontal Z-shaped profiles, which are also a horizontal crate of structural stiffness, eliminates the possibility of condensation on the supporting racks and guide profiles, and also reduces internal stresses associated with the temperature difference on the outer and inner surfaces, which are outside depending on the outdoor temperature are located in a constant "warm zone". In addition, the presence of an additional heat-insulating layer increases the fire resistance of the structure and contributes to an even distribution of temperature on the inner surface of the wall and allows its use in a medium-aggressive environment.

The implementation of the facade without reference to the dimensions of the wall panels through the use of a detailed assembly provides the ability to perform architectural forms of any complexity and the formation of window openings of any complexity and dimensions, and also ensures the absence of expansion joints from both the external and internal sides of the enclosing structure (wall).

Thus, the proposed arrangement of the facade significantly increases the reliability, service life and thermal performance of the structure, provides the ability to perform architectural forms of any complexity and improves manufacturability due to the absence of the need to use heavy mechanization for unloading and installation work.
