Abstract

The technical effect of the proposed utility model is to raise the thermal insulation capacity of a metallic door. A door is designed with four rabbets along the perimeter of a leaf and with corresponding ledges on a doorframe which are arranged on the surface of the doorframe opposite the ledges of the leaf. The technical effect is achieved on account of the smaller difference in temperatures between the rabbets, providing a thermal gap which provides a significant reduction in heat transfer. Each rabbet is equipped with a seal.

Description

4-DOOR DOOR

Utility Model Description

The invention relates to the construction of a predominantly metal door.

Known "Door block" RU 51076 [2], contains a door frame consisting of four hollow elements, each of which is made of sheet metal by bending with the formation of the front wall, vestibule and rear wall, and a flat door leaf, the end surfaces of which are adjacent to surfaces of the narthex and have a mating form with them. The narthex of all four elements has a two-stage cross-sectional shape with the formation of the first and second flat steps parallel to the planes of the door leaf.

The disadvantage of this device is the low heat-insulating ability of the door.

The closest technical solution is “METAL DOOR BOX PROFILE” RU 142032 [1], made with narthexes - steps along the perimeter of the canvas and corresponding, located on the surface of the box, opposite the steps of the canvas, steps in the canvas, a step in the canvas and a step in the box opposite said steps in the canvas form a narthex.

The number of narthex is increased to three, which increases the heat-insulating ability of the door.

The disadvantage is the lack of insulating ability and low reliability.

The technical result of the proposed utility model is to increase the insulating ability.

The technical result is achieved by the fact that the door is made with vestibules - steps along the perimeter of the canvas and, correspondingly, located on the surface of the box, opposite the steps of the canvas, steps on the box, (the step in the canvas and the step in the box opposite the specified step in the canvas form a narthex), characterized in that it contains 4 narthex.

Each narthex can be equipped with a seal. Sealers can be located on the surface of the box, on the surface of the canvas and at the same time on the surface of the box and the canvas. The presence of gaskets will further increase the heat-insulating ability of the door.

The narthex can be arranged in pairs, which allows you to place between the pairs of beams and loops.

The door may contain a latch regulator, which will allow you to adjust the compression ratio of the sealant and the position of the door depending on weather and other conditions.

The box can be closed, which will increase the strength and heat-insulating ability of the door.

Doors with 4 vestibules are shown in: FIG. (section), where:

1 - box;

2 - canvas;

3 - the first narthex;

4 - the second narthex;

5 - the third narthex;

6 - the fourth vestibule.

The device operates as follows: when closing the door, door 2 is pressed against the box 1 by any known device. On the box and the sheet there are flat areas corresponding to each other, the planes of which are parallel to the plane of the sheet and the plane of the box, respectively. The areas between the sites are perpendicular to the sites and perpendicular to the common planes of the canvas and the box, respectively. Pairs of such opposed sites form respectively the first 3, second 4, third 5, fourth 6 porch. The narthexes are equipped with sealing means - gaskets. The peripheral parts of the box and the web can be produced by rolling from steel strips followed by welding of the corner parts or by any other known method. The box can be performed in a closed section by welding a steel sheet from the outside. The door leaf can be made of metal sheets, or combined, for example, of wood and coated of metal sheet. Holes for crossbars, sections for fixing loops, recesses for the seal may be located on the box and the web. A door with an increased number of narthexes has increased reliability due to the reduction of heat loss in case of loss of tightness of one of the seals, since the rest of the seals will provide the function of tightness of the door. Also, the inventive door has greater rigidity and strength compared to the closest analogue due to the increased number of stiffeners formed by the steps of the canvas.

EFFECT: increased heat-insulating ability is achieved due to a smaller temperature difference between narthexes providing thermal break, which provides a significant reduction in heat transfer.

Industrial applicability. The claimed design and technical solution can be successfully used for the manufacture of doors with high thermal insulation ability.
