Description

This utility model relates to doors for residential and industrial premises.

A metal door with a thermal break is known from the prior art (patent for utility model RU 178 544, publ.: 06.04.2018 Bull. No. 10), which is mounted on hinges in a frame containing an external metal sheet and an interior trim panel, metal profiles, a panel made of heat-insulating material, the frame is made of thermal break from the same material as the door, while metal profiles were used to lay insulating materials, fix them rigidly and form the exterior, flexibly laid along the inner perimeter of the frame th seal, the frame is made of three separate profiles with two thermal breaks between them. The disadvantage is the low heat-saving ability.

Closest to the claimed technical solution is the door frame (patent for utility model RU 180373, publ. 08.06.2018 Bull. No. 16), which includes the external and internal parts made of steel profiles, as well as inserts of heat-insulating polymeric material, located between the outer and inner parts of the door frame, the inner part of the door frame is provided with L-shaped protrusions directed counterclockwise to form a longitudinal gap, the outer part is provided with L-shaped protrusions, L-shaped protrusions of the outer part and recessed into the gap between the L-shaped protrusions of the inner part of the door frame, the inserts are made in the form of hollow PVC profiles of a U-shaped cross section with internal partitions and are installed on the edges of the L-shaped protrusions of the inner part. The disadvantage of the design of the closest analogue is poor thermal insulation.

The task to which the claimed utility model is directed is to expand the arsenal of doors by developing a door with enhanced thermal insulation properties for rooms for various purposes.

This problem is solved due to the fact that the door includes the outer and inner parts of the door frame, the outer and inner parts of the door leaf, a heat-insulating polymer material located between the outer and inner parts of the door leaf, seals, including thermal breaks, also include a two-chamber thermal gap of the door cloths, which is also an intermediate element when connecting the outer and inner parts of the door leaf and fastened with rivets and self-tapping screws, includes a two-chamber thermor opening of the door frame, which is also an intermediate element when connecting the outer and inner parts of the door frame and fastened with rivets and self-tapping screws, while thermal breaks are made in the form of a hollow rectangular profile having an internal partition dividing the internal space into two chambers with air on the door leaf polymer seals are installed, a magnetic seal is installed on the inside of the door frame. As a heat-insulating material, polystyrene foam with layers of mineral wool strips is used. Thermal breaks are made of rigid unplasticized PVC.

The technical result provided by the given set of features is to reduce the heat loss of the structure (increase thermal insulation properties) of doors for rooms for various purposes.

The utility model relates to the field of production of door steel blocks with installed locking devices for buildings and structures for various purposes.

The door is made of a door frame, consisting of the outer 1 and inner 2 parts of the door frame, and the door leaf, consisting of the outer 3 and inner parts of the door leaf 4. The door leaf inside is filled with polystyrene foam 6 with interlayers of mineral wool stripes 5.

The door contains a two-chamber thermal break of the web 7 and a two-chamber thermal break of the box 8. These thermal breaks are made of rigid unplasticized PVC (polyvinyl chloride) and have two chambers with air, made preferably of a rectangular shape. This thermal break is made along the entire perimeter of the canvas and duct, i.e. made in the form of a frame. Thus, the thermal break is a hollow rectangular profile made of rigid unplasticized PVC, having an internal partition dividing the internal space into two chambers with air.

The hollow thermal fracture profile (frame) in the bearing capacity is not inferior to the metal one, and exceeds the tens of times in terms of thermal performance. The thermal conductivity coefficient of steel is 52W / (sq. K), and PVC - 0.20 W / (sq. K). Thanks to this, the problem with the “cold bridge”, as well as with ice on the door in the winter, almost completely disappears. In comparison with such a popular material for thermal break as cork sheets, MDF and others - the PVC frame is not subject to getting wet and does not serve as a breeding ground for mold. Another disadvantage in using cork, substrates made of polyethylene, polystyrene foam and the like, as well as MDF is the use of through metal fasteners, which are “cold bridges” and do not allow to achieve effective thermal break.

In the proposed door structure, the problem of the formation of “cold bridges” when using through metal fasteners is solved by fastening metal structures with fasteners to different planes of the frame and the metal parts do not touch each other anywhere. The design of thermal breaks 7 and 8 is made of rigid unplasticized PVC (polyvinyl chloride) in the form of a regular square with a partition inside to give rigidity and to divide the internal space into two chambers with air. This part is used both in the construction of the box and in the design of the door leaf. In the design of the thermal break box, it is an intermediate element when connecting the outer 1 and inner 2 parts of the door frame and is fastened with rivets 12 and screws 13. In the design of the door leaf, the thermal break is an intermediate element when connecting the external 3 and inner 4 parts of the door leaf, and is fastened with rivets 12 and self-tapping screws 13. Fixing the thermal break profile with rivets and self-tapping screws allows to reduce the heat loss of the structure due to the fact that there is a denser clip of the profile to the metal the door frame and frame.

Rubber sealant 9 is a rubber sealant for metal doors without adhesive, manufactured under the brand name RG-031, and has a triangular shape.

The magnetic seal 10 is a door seal made of elastic material, which is a casing of two chambers parallel to each other elongated one above the other, in one of which, having the shape of a hollow parallelepiped, a magnetic insert is placed, the other chamber has the shape of a corrugation with a diamond-shaped cross section.

Seal 11 is a Profitrast SD-1 self-adhesive seal. Such seals are used to seal and seal window and door blocks to eliminate drafts, moisture and dust, and create effective heat and sound insulation. This seal is made of EPDM foamed rubber with an EXTRAFIX adhesive layer and is made in a rectangular shape, rounded on one side.

The tests carried out established that the door in terms of its technical characteristics meets the requirements of SP 50.13330.2012 “Thermal protection of buildings”.
