Abstract

The invention relates to the field of construction, namely, the erection of enclosures and coatings for residential, civil and industrial buildings. The three-layer panel includes upper and lower panels, which are made of smooth, profiled or corrugated steel or composite sheet and bonded to the adhesive layer mineral wool insulation with cross-oriented fibers. The length and width of the panel consists of individual insulation strips, which are stacked with displacement in length (stepped). In the seams between the rows of insulation the entire length of the panel has vertical reinforcing elements of a straight or stepped profile of the expanded-mesh grid.

The invention belongs to the field of construction, namely to the construction of enclosing structures and coverings of residential, civil and industrial buildings.

A three-layer panel design is known, which includes the upper and lower skins, connected by glue with a layer of mineral wool insulation with transversely oriented fiber direction.

The insulation along the length and width of the panel consists of individual lamellas, laid with an offset along their length, while between the insulation layer and the skins there is a mesh made of synthetic material, for example, polypropylene, equipped with spikes located in its nodes, oriented in the insulation layer (11.

The disadvantage of the known design is the increased consumption of material. In addition, the presence of spikes in the mesh made of synthetic material does not affect the shear resistance of the insulation. There is also a question about the commonality of the work of the specified grid and the panel cladding sheets.

The closest analogue to the declared object is a three-layer wall panel, which includes the upper and lower skins, connected to each other by glue with a layer of mineral wool insulation with a transversely oriented direction of the fibers, which consists of individual lamellas laid along the length and width of the panel with a shift in their length. Reinforcing elements are installed in the supporting areas between the rows of lamellas in the direction of the length of the panel for 1/4-1/5 of its length. At the same time, the upper and lower edges of the reinforcing elements are made of a toothed profile, and the ends of the teeth rest against the inner surface of the skins |21.

The disadvantage of the well-known three-layer panel is the imperfection of the constructive solution of the reinforcing elements, which can cause a violation of the integrity of the lower and upper skins, and, as a result, the destruction of the panel itself. In this case, the impact of reinforcing elements located exclusively in the support areas of the panel on the bending stiffness of the structure as a whole is insufficient.

The technical problem solved by this invention is to increase the load-bearing capacity of the panel structure by installing between the rows of lamellas along the length of the panel vertical reinforcing elements made of a cross-exhaust mesh.

The technical result is achieved by the fact that in the well-known three-layer panel, which contains upper and lower steel skins, connected by means of a two-component glue with a layer of insulation made of mineral wool, unlike the closest analogue, the internal vertical reinforcing elements are made of a cross-exhaust mesh. This makes it possible to increase the load-bearing capacity of the panel without using additional anchoring means, since the design of the cross-exhaust mesh ensures reliable adhesion of the latter to the fibers of the mineral wool insulation. Reinforcing elements from the cross-extraction mesh form the inner edges of the panel, which leads to an increase in the strength and stiffness of the panel both in compression and bending.

In fig. 1 shows the general view of the proposed three-layer panel with rectilinear reinforcing elements, where: 1 - lower panel cladding, 2 - upper panel cladding, C - insulation lamellas, 4 - rectilinear reinforcing elements.

In fig. 2 shows the general view of the proposed three-layer panel with stepped reinforcing elements, where: 1 - lower panel cladding, 2 - upper panel cladding, C - insulation lamellas, 4 - stepped reinforcing elements.

In fig. C shows the proposed three-layer panel with vertical reinforcing elements of a stepped profile in a three-dimensional view, where: 1 - lower panel cladding, 2 - two-component glue, C - mineral wool insulation lamellas, 4 - upper panel cladding, 5 - stepped reinforcing elements from average exhaust grid.

The three-layer panel contains the lower (1) and upper (2) steel skins, connected using a two-component glue (3) with a layer of insulation made of mineral wool (4) with transversely oriented fibers, which consists of separate lamellae along the length and width of the panel. laid with an offset (stepwise). Between the rows of lamellas, vertical reinforcing elements (5) made of cross-exhaust mesh of stepped (or rectilinear) profile are laid.

The production of the declared structure is carried out continuously as follows. The upper and lower skins of the panel are made of galvanized steel of a given thickness, which is supplied from two rolls to the profiling section. Fast-hardening two-component glue is applied through nozzles in a thin layer to both skins. At the same time, mechanized cutting of mass-produced mineral wool plates into separate insulating lamellas with a thickness equal to the thickness of the panel takes place outside the profiling section. Laying of insulation lamellas is carried out manually with a shift along their length. The installation of vertical reinforcing elements in the places marked along the length of the future panel also takes place here. The formed heat-insulating core of the panel is mechanically fed into the automatic loading module of the technological line, after which the current pressing and parallel formation of the lock joints of the skins takes place. Under the action of uniform pressure, the two-component glue quickly hardens, thus forming a solid "sandwich". Upon completion of the pressing operation, the finished panels are cut to a predetermined length.

The general scheme of continuous production of a three-layer panel is shown in Table 1.
