METHOD OF MANUFACTURING A ELEMENT STRUCTURE AND

ELEMENT STRUCTURE

The invention relates to a method and a device for a housing-like element structure made of sheet metal and a thermal insulation attached to its inner surface, for example for an air-conditioning use, inside which a duct is formed.

5 Conventionally, air conditioning ducts are made of sheet metal and wool boards using various support and form strips, as well as sheet metal folding supports. The dampers and moldings are connected to each other with screws, rivets and spot welding. The ductwork is connected to each other by flange and work rail connections. The ductwork 10 is typically made of sheet metal and wool board as more or less handrails.

However, the disadvantage of the manufacturing method is the slowness of the manufacturing process as well as the high material loss of the material used in the manufacturing process. Correspondingly, the disadvantages of the finished product include the fact that the product cannot be delivered finished. In addition, the fire dimensioning of the product is more limited and the tightness of the product cannot be adequately monitored.

The object of the present invention is to provide a new method for manufacturing an air conditioning duct 20 and an air conditioning duct which does not have the above-mentioned drawbacks.

'· ·

The method according to the invention is characterized in that the element structure is assembled from composite sheets made of sheet metal and thermal insulation, which are fastened to each other on sheet metal sheets of at least two parallel composite sheets by anchored support and / or form members.

In addition, the device according to the invention is characterized by the composite plates of two or more successive element structures 2 91990 being fastened to each other in such a way that the edges of the composite plate plates are bent so far between the opposing surfaces of the composite plates.

By means of the method according to the invention, it is possible, for example, to manufacture the outer casing of instruments and chambers of air conditioning ducts from industrially produced thermal insulation-sheet metal composite sheets or other similar materials.

In addition, the use of the device according to the invention is characterized in that the element structure is used as a fire, thermal and sound jacket for ventilation devices or similar duct, device or chamber structures.

Fig. 1 shows a housing-like element structure 10 made of sheet metal 11 according to the invention and a heating element 12 fixed to its inner surface. A channel 13 is formed inside the element structure 10, and the structure 10 formed therein is suitable for use, for example, in fire, fire and ventilation systems.

The element structure 10 comprises composite sheets 20 made of sheet metal 11 and mineral wool 12, which are fastened to each other on sheet metal sheets 11 of two parallel composite sheets 20 by anchored support and / or form members 40 to provide a load-bearing structure. From the element structures 10 manufactured by the new method, duct, device or chamber structures with fire and 20 thermally insulated are manufactured.

As the manufacturing material, a composite sheet S 20 is used, the structure of which consists of a glued sheet-mineral wool-sheet metal composite. The material is made by different cutting methods and by bending duct sections, which are connected to each other. The inner and outer connecting surfaces 35 of the element structure 10 are sealed at the joints and joints. The 10 kMyttd of the elements also does not impose any restrictions on the shape of the ductwork.

The sheet metal surfaces 10 pre-treated with different shade options do not require a separate surface treatment afterwards, and thus a well-groomed appearance of the product is obtained. The fastening of the shaped composite sheets 20 to each other is quick and clean and the fastening is done both from the inside and the outside. The 91990 4 element structures 10 assembled at the installation site are mounted with duct brackets 44 either on the roof and wall structures or as separate load-bearing structures as parts of support columns or the like. The lightweight prefabricated parts 5 of the prefabricated structures 10 are transported as parts to the construction site and the parts can also be manufactured into larger assemblies.

Figure 2 shows the connection of two adjacent composite plates 20 of the element structure 10 to each other. The joint surfaces 35 of the composite plates 10 are cut at an angle of 45 ° 10. The outer corner 46 of the element structure 10 is reinforced with an L-shaped corner piece 40. Between the corner piece 40 and preferably 1 Iranian thick sheet metal plates 11, a cellular rubber seal 33 of the desired sealing class is placed. an arrow corner 51 made of aluminum or rubber is placed in the inner corner 47 and fixed to the element plate 20 with screws or glue.

20 The solution provides a very sturdy and compact structure.

Figure 3 shows how the composite plates 20 of two successive element structures 10 are fastened to each other. The edges 23 25 and 24 of the sheet metal sheets 11 of the composite sheets 20 are bent so as to elongate the opposing surfaces of the composite sheets 20 so that a tongue-and-groove joint 21 can be formed. towards. In this way, the formation of cold bridges is avoided in the structure.

The seal 60 placed between the edges 23 and 24 of the tongue joint 21 is compressed when the clamping legs 52 are tightened, thus providing a fireproof and tight joint.

35 In the example solution, the inflatable tensioning foot 52 of the composite plate 20 5 91990 is used. As the sealing materials 60, for example, a sponge rubber band or cellular rubber can be used.

Correspondingly, the projections 41 of the clamping leg 54 are locked in corresponding holes drilled in the housing 20 of the element 10. The fixing legs 53 and 54 are additionally fastened to the housing 11 of the element with screws 31.

Two fastening legs 53 or 54 are required for each of the tightening joints. When the surfaces of the clamping legs 53 or 54 are fastened and tightened against each other, the fastening of the ductwork parts relative to each other is always correct, and at the same time the correct deflection of the seal is achieved.

: Figures 6A to 7B show duct brackets 55 and 56 for connecting duct sections. Each part of the duct bracket, which is divided into two parts, is connected to the seats 10 of two successive element structures. The plate-like alignment projection 41 is inserted into the alignment hole made in the sheet metal plate 11 and fastened to the plate 11 by fastening screws 30 31 or rivets. The ductwork parts are locked together by means of easily removable fastening wedges 42 and 43, which, by removing them from the finished air-conditioning ductwork, can be used to remove the element structure 10 away from the maintenance work.

Figures 10A and 10B show an H-strip 68 securing both surfaces of the element plate 20, consisting of three sheet metal plates welded together and shaped. In Figures 20B and 11C, again, only a strip 69 is fastened to the surfaces of the second element plate, which consists of three sheet metal plates welded together and shaped.

Fig. 12 shows the tongue-and-groove joint shown in Fig. 3, in which the composite plates 20 of the two perforated element structures 10 are fastened to each other.

The edges 23 and 24 of the sheet metal sheets 11 of the composite sheets 20 are bent so far between the opposing surfaces of the composite sheets 20 that a tongue-and-groove joint 21 can be formed therefrom. towards. In the structure thus obtained, the formation of cold bridges is avoided. Gaskets are placed between the joint connection 21 to provide a fireproof and tight connection 35.

The edges 25 5 and 26 of the sheet metal sheets 11 of the composite sheets 20 are bent so far between the opposing surfaces of the composite sheets 20 that a tongue joint 22 can be formed therefrom. towards. In the structure of NM, cold bridges are also formed. Seals are placed in the vice of the joint 22 to provide a fireproof and tight connection.

As sealing materials 32 and 33, for example, 15 sponge rubber strips or cellular rubber seals are used. The parts of the element structure 10 are connected by means of different clamping legs. Two fixing legs are required for each tightening joint, which can be either inside or outside the element structure 10. When the opposing surfaces of the clamping legs 20 are fastened to each other, the fastening of the ductwork parts relative to each other is always correct, and at the same time the correct depression of the seals 32 and 33 is achieved. With the help of the formed shell structure, the element structures 10 can be classified as fire into classes which cannot be reached by the old construction methods.
