Description

Three layer sandwich panel

The proposed utility model relates to modular construction and can be used to create elements of residential, industrial buildings, warehouses, canteens, workshops, shops and other objects for various purposes.

Known three-layer panel type "sandwich, manufactured by a closed joint-stock company" Petropanel / PETROPANEL 2001, SPB, 2001, p.6 /, containing two profiled metal sheets glued on both sides to a specially designed and glass-free mineral wool board with a density of more than 115 kg / m The panel is provided at opposite ends with nodes for connecting to the lock with a similar panel. This design is selected as a prototype.

The disadvantage of the prototype is, firstly, its lack of strength, for example, with a span of 3 m, a roof panel with a thickness of 100 mm has an allowable load of 117 kg / m, although in accordance with building codes and regulations, the total normative snow load for central Russia is 160 kg / m Secondly, the lock nodes do not provide sufficient tightness.

The task solved by the utility model is the elimination of these shortcomings. To solve this problem, a three-layer sandwich panel is proposed, containing two profiled metal sheets glued on both sides to mineral wool insulation and equipped at the opposite ends with nodes for connecting to the castle with a similar panel. A distinctive feature of the proposed panel is that the insulation is made of mat assembled from longitudinal rods interconnected along the side and end surfaces and

IPC E04C2 / 26

oriented so that the mineral wool fibers are located mainly perpendicular to the surface of the metal sheet.

In addition, it is proposed to connect adjacent longitudinal rods together indispensably on the lateral surfaces.

Additionally, it is proposed to adjacent adjacent longitudinal rods to be connected together inextricably on the end surfaces.

As an integral joint, an adhesive joint is offered.

The structural design of the above three-layer panel type "sandwich

allows you to increase the strength properties of this building element, both in compression and in

and lateral bending. In addition, the presence of a seal in the groove of the assembly for connection to

the lock allows you to make the connection of the panels tight, preventing the penetration

moisture, steam and air into the room, and also prevents the penetration of moisture

directly into the insulation. Thus, a technical result is achieved.

Figure 1 shows a transverse section of the panel, figure 2 shows a longitudinal section thereof, figure 3 shows a node for connecting to a lock with a groove, where 1,2 profiled metal sheets, 3, 4 - nodes for connecting to a castle with a similar panel, 5 - 25 - longitudinal rods of mineral wool, 26 - sealant. Neighboring rods, for example, 5 and 6 are interconnected inseparably by adhesive bonding on the side surfaces. Neighboring rods, for example 5 and 12, 6 and 13 are interconnected one by one on the end surfaces with an adhesive joint. Profiled metal sheets are also glued to the insulation rods. For a durable connection of metal sheets with insulation and longitudinal rods to each other, polyurethane adhesive can be used. As a sealant, a sealing compound can be used applied to the surface of the groove of the assembly for connection to the lock.

The panel is made as follows. The canvas, cured with a binder of mineral wool, is cut into rods with a width equal to the thickness of the middle layer of the panel. The rods rotate 90 ° around their longitudinal axis. The rods are assembled with connection along the lateral and end surfaces with the formation of a mat, in which the main fibers of the longitudinal pieces are located perpendicular to the plane of the panel, and the width of the mat corresponds to the width of the panel. If it is necessary to obtain panels of special quality, the previous operation is carried out using polyurethane adhesive. Then, metal sheets 1 and 2 are attached, but both sides of the insulation by means of glue, simultaneously pulled through a roller press, and thereby profile the metal, as well as nodes 3 and 4 for fastening to similar panels on opposite ends of the product. If necessary, corrugations are pre-created before gluing to the insulation.

The use of a utility model will improve the strength properties of three-layer

1 panels of the type “sandwich”, and will also make the connection of the panels airtight.
