Abstract

The invention relates to construction and can be used in industrial and civil construction as a walling. It allows to increase the operational reliability, form stability and reduce the consumption of materials of the panel when using insulation from low-strength casting foam. On one of the longitudinal sides of the panel, the edges of the casings 1 are made with steps 4 to form a butt joint, and each step 4 is made with a bend 5 on the longitudinal side of the panel, the end 6 of which is bent and backed up in insulation 2. The ratio of the width of the horizontal section of step B to the anchorage depth in the insulation of the end of the limb A is determined depending on the thickness of the panel H, the thickness of the limb H, the modulus of elasticity of the core and the reduced modulus of elasticity of the heater. 2 Il.

The invention relates to construction and can be used in industrial and civil construction as a walling.

The aim of the invention is to improve the operational reliability, form stability and decrease the material consumption of the panel when using insulation from a casting low-strength foam.

FIG. 1 shows a panel, cross section; in fig. 2 - the same, the cross section in the area of the ledges.

The construction panel of the enclosure includes thin-sheet platings 1, between which the filling insulation 2 and the bordering edge 3 are placed along one longitudinal side of the panel. The material of the skins can be, for example, metal, plastic, and the material of the ribs, for example, plastic, wood, metal. The other longitudinal side of the panel has the edges of the skins 1 with steps 4 to form a butt joint, and each step 4 is made with a bend 5 on the longitudinal side of the panel, the end 6 of which is bent and annealed in insulation 2.

The width of the horizontal portion of the step 4 is determined from the conditions for the formation of a butt joint with the necessary thermal and physical characteristics determined by calculations for thermal conductivity, air permeability, etc.

The thickness of the bend 5 on the longitudinal side of the panel is determined by the stability of the plating, the thermal requirements, as well as the condition of filling the cavity formed by step 4 and the bend 5 with the casting insulation 2. The thickness of the cavity formed by the ends of the 6 bend 5 must be somewhat larger than the diameter of the casting heads feeding polymer composition.

The depth of the anchored end 6 of the bend 5 is taken from the condition of reliable reinforcement of the casing 1 in the ledge zone 4 with a layer of casting insulation 2 (filling the cavity formed by the ledges 4 and the bend 5), as well as by the ends of the 6 bend 5.

The proposed construction of the panel allows the use of a continuous technology for manufacturing a panel with a low-strength insulation, but the ratio of the width of the horizontal section of the step to the depth of anchorage to the insulation of the end of the limb should satisfy the expression:

insulation;

The panels are manufactured in the following sequence.

The prepared profiled ribbons (upper and lower sheets of casings) are supplied by the conveying devices simultaneously with the longitudinal plastic edge of the channel section. Rolling metal sheets and joining them by squeezing to the shelves of a plastic channel is carried out. After applying the adhesion layer, sheets with one longitudinal rib attached to them pass a pouring station, where a filling head is automatically inserted into the process gap formed by the ends of the bends, and during its reciprocating motion. Then, the technological gap through which the filling was made is closed with a tape of a heat insulating gasket. Sheets with a double-belt conveyor composition are moved inside the forming unit, where foaming and curing of the phenolic composition takes place. At the exit of the forming device, the finished panels are cut to measured lengths using a cutting device. The entire panel manufacturing process is carried out continuously in automatic mode.

Anchoring in the foam ends of the bends with the accepted restrictions of their size allows to increase the stability of the skin in the ledge area and thereby prevent the possibility of flaking of the skin from the insulation when exposed to wind load in combination with temperature difference across the panel, which increases the operational reliability of the panel
