Description

The invention relates to the construction and can be used in the construction of light industrial industrial fencing industrial and public buildings and structures.

The purpose of the invention is to increase the durability, manufacturability, reduce fire hazard panels when using composite insulation in the cavity of the panel.

Figure 1 shows the proposed panel section; Figures 2 and 3 are diagrams for determining the distance between the strip elements (curve 1 - with a thickness of 8 cm of insulation, a curve of 2-10 cm, a curve of 3-12 cm, a curve of 4-14 cm, a curve of 5-16 cm).

The fence panel contains a bearing profiled lining 1, insulation 2, a fastener connection made of strip elements 3, Z-shaped at the ends, welded or bolted connection 4. A waterproofing layer is made of the insulation part of the insulation or the external covering 5 is laid.

The strip elements are located across the panel and rigidly fixed (by welding, rivet, bolts) on the shelves of the profiled carrier casing 1. The distance between the strip elements 3 along the panel length is determined by the equation

where I is the distance between the strip elements;

n is the coefficient depending on the conditions of supporting and fixing the panel.

The strip element 3 has end and middle flat sections located parallel to the plane of the bearing profiled lining. Between the end and middle sections there are curvilinear sections with a radius of rounding equal to the height of the heat insulating layer of the panel. The thickness of the insulation is determined by the distance from the outer skin 5 to the upper flange of the profiled skin. The length of the end portions is assumed to be half the width of the flange of the profiled trim panel. The middle section of the strip element must be at a distance of ± 10% of the height of the thermal insulation layer from the carrier profiled support.

Metals and polymeric composites of low Flammability (phenol-formaldehyde, phosphate, and other fiberglass plastics) are used as the material of the profiled plating, and as a heat insulation material - difficult-to-burn. For example, lamination foam is a cement insulation (with a density of 150–120 kg / m2), which is molded directly in the panel’s internal cavity, as reinforcing connections — strip metal and low-combustibility composites (for example, phosphate-glass); qualities of the waterproofing layer - roofing material on bitumen mastic.

Panel fencing is made as follows.

On the supporting profiled lining, the surface of which is grounded with an anticorrosive composition, strip elements are fixed by welding, rivets or bolts. Their length corresponds to the width of the panel, the width of the element 25 - 30 mm, thickness 2-5 mm. Then a mobile formwork is installed on the cladding sheet and the internal cavity of the panel is filled with a polymer or polymer mineral composition, which is molded and cured. The fasteners are embedded within the insulation volume and ensure reliable joint operation of the carrier casing and insulation. The formwork is removed from the panel and either a waterproofing layer is applied (for the roofing panel) or an external facing (for the wall panel) is fixed by one of the known methods. After that, full factory readiness panels are stacked for subsequent shipment to the construction site.

When using polyethylene foam cement as insulation, the distance is

between the reinforcement links of the strip elements can be determined from the diagrams presented in Fig.2 (roof panel) and 3 (wall panel). For example, it is necessary to determine the maximum distance between the strip elements of a single-span roofing panel with a thickness of 140 mm and a density of 200 kg / m2. According to the diagram of FIG. 2, proceeding from these values, along curve 4, there is a 5 d t distance of 200 cm, which corresponds to the distance between the strip elements.

Increase of durability and reduction of fire danger of fencing panels

0 is achieved by using fasteners in the form of strip elements (instead of adhesive joints) to ensure the joint operation of the carrier profiled sheathing and insulation.

5 In addition, the use of discretely spaced reinforcing links makes it possible to use slow-burning insulators that have increased rigidity, in combination with profiled sheathing sheets with increased deformability.

Forming insulation directly in the internal cavity of the structures makes it possible to use continuous high-performance panel manufacturing technology. The panels of the proposed design also allow assembly of light fences of buildings using a block method using assembly cards.

0 The main area of application of the panels of the proposed design is the main buildings of power stations (including nuclear power plants), which are fire-resistant to Ilia. Panels meet the requirements
