Description

(54) REFRIGERATING CAMERA

Technical field

The invention relates to a prefabricated refrigerator that will find application in the construction of industrial refrigerators, building blocks and volumes.

BACKGROUND OF THE INVENTION

A prefabricated refrigerating chamber is known, comprising vertically stacked multilayer panels made of sheet layers and a thermal insulation layer, the panels being connected to each other / 1 /.

The disadvantages of the known solution are:

- more complex implementation of the camera due to the use of planar and angular wall elements produced by different technologies, complex connection between the panels.

It is an object of the invention to provide a prefabricated refrigerated chamber composed only of planar elements, with simplified connections between them.

SUMMARY OF THE INVENTION

The problem is solved by a prefabricated refrigerating chamber, comprising vertically arranged multilayer panels, made of sheet layers and a thermal insulation layer, the panels being interconnected in front.

Two opposite walls of the camera are made of vertically stacked multilayer panels. The other two opposite walls are made of horizontally arranged multi-layered panels. Each multilayer panel consists of a permanently bent elastic thermal insulation layer with parallel walls, between which are two outer sheet layers and a middle sheet layer interconnected by connecting means. On the outer surface of the thermal insulation layer, slits are metrically filled in which a lining is inserted. The multilayer panels are arranged between horizontal and vertical C-shaped guide profiles, which are located at the edges of the chamber and are fixedly connected to each other and to the floor structure. The arms of the i-shaped guide profiles are inserted between the outer supporting layers of the panels and the non-glued edges of the thermal insulation layer.

Advantages of the solution are:

- the prefabricated refrigerator compartment consists only of planar elements with two of the opposing walls being made of vertically stacked multilayer panels and the other two opposing walls being made of horizontally stacked multilayer panels;

- the connections between the structural layers are simplified due to the fact that each multilayer panel consists of a triple-bent elastic layer (thermal insulation) with parallel walls, between which are two outer sheet layers and a middle sheet layer interconnected by connecting means;

- the connection between the cladding and the panels has been simplified, due to the fact that slots in which the edges of the cladding elements penetrate are metrically made on the outer surface of the thermal insulation layer;

- the angular connections of the plan are simplified by profiles, which are located in beds of the elastic thermal insulation layer, also formed by means of metrically executed sections;

- the angular connection at the ceiling-wall is also simplified due to the fact that the C-profile, with a protruding rib, is arranged in beds formed at the end of the panels between the sheet layers and the edges of the triple-bent elastic thermal insulation layer in the area of the metric slits.

Examples of carrying out the invention

According to FIG. 1, the four corners of the chamber are formed by means of C-shaped guide profiles 9 gripped by connecting means 10 to the outer foliation layers 6. The lining edges 11 are arranged in metric slots 7.

According to FIG. 2, at the floor, the outer foliage layers 6 of the vertical panels 1 are supported to the shoulders of two i-shaped guide profiles 9. The middle sheet layer 4 is freely disposed in the i-profiles 9. Both profiles 9 are fixed to the floor plate. The horizontal ceiling panels 1 lie on the upper профи-profiles 9-a having protruding ribs 14 that close the shorter sides of the ceiling panels 1. To these ribs 14 are attached closing panels 15. The lower part of the ceiling panel is provided with an inner lining. 11th having shorter ribs located in metric holes the elastic layers 7 of the elastic thermal insulation layer 2.

According to Fig. 3, the ceiling panels lie on the horizontal wall panels 1, and the connection between them is made by means of upper and shaped guide profiles 9-a having projecting ribs 14 or by means of corresponding i-profiles 9, horizontally and mutually perpendicular to each other and attached to each other by a welded plate. The attic panels on the side of the premises have a lower inner lining 11th with shorter ribs. With this lining, the panels rest on horizontal and shaped guide profiles 9, fringing the horizontal wall panels from the other two opposite walls. These two walls are protected by an outer lining 11 whose ribs are oriented horizontally and are fixed to the slots 7 of the triple-bent elastic thermal insulation layer 2. The surface layer of the upper lining 11 overlaps the surface layer of the lower lining 11, which causes water to repel outside the air spaces formed by their ribs. At the upper corner, panels 1 are further protected by a closing skirt 15.

According to FIG. 4, the multilayer panel consists of a triple-bent elastic thermal insulation layer 2 with parallel walls. Between them are two outer sheet layers 6 and a middle sheet layer 4, interconnected by connecting means 12. Metric slots 7 are provided on the outer surface of layer 2. Two convex semi-cylindrical portions 3 are formed on the left side of panel 1. 2 with one slot 7 in the middle. Between these two convex parts 3 is the projecting end of the middle sheet layer 4. On the right side of the same panel, opposite the middle sheet layer 4, there is a third convex semi-cylindrical part 5 belonging to the layer 2, and in the middle there is also a slot 7. This part 5 rests on the projecting edges of the two outer sheet layers 6, whose edges on the side of the outer edge 8 of the elastic insulation layer 2 are not glued.

According to FIG. 5, in the connection between two adjacent panels, all the convex semicylindrical parts 3 and 5 are pressed together to form almost straight lines in section. This is possible because the panels are fixed once to the shaped guiding profiles 9, stabilized to the floor and to the upper horizontal profiles 9 and 9-a covering the panels at their upper end, and secondly the outer sheet layers 6 and the middle sheet layer 4 are interconnected by means of coupling means 12.

According to FIG. 6, in the vertical panels 1 at the upper end is inserted an i-shaped guide profile 9-a having a projecting rib 14. The short walls of profile 9-a are fixed to the non-glued edges of the two outer sheet layers 6. The horizontal wall of II profile 9 -a shorter ribs 13 are designed to stabilize the ceiling panels 1. These ribs 13 are at the same metric distance as the slots 7 of the elastic layers 2 of the ceiling panels 1. In height they are equal to the height of the short ribs belonging to exterior cladding 11-a.

According to FIG. 7, the upper i-shaped guide profiles 9 are fixed to one of the outer sheet layers 6 by connecting means 10. The outer two convex semi-cylindrical parts 3 of the resilient thermal insulation layer 2 are enclosed by a protective profile 12-a, whose ribs are arranged in the slots 7 of the parts 3 and the upper edge of the protective profile 12-a is freely disposed below the last edge of the roof lining 11.

According to FIG. 8, the multilayer panel 1 on the right side has non-glued edges 8 formed with an outline that is 1/4 of the cylindrical surface. These ends 8 are an integral part of the thermal insulation layer 2 and are located after the first or last slit 7 of the triple-bent elastic thermal insulation layer 2. 5
