Panel

 

(57) Abstract:

The invention relates to the construction, namely the construction of fencing panels on a lightweight type. The panel includes a frame, a plate, fill units of bars with sootnosheniem of length to width is 15 - 25, forming a three-beam star, collected in a diamond shape, vertices, which combines a reinforcing element in the form of a tape or strip. This embodiment allows to reduce the consumption of materials. 3 C.p. f-crystals, 3 ill.

The invention relates to the construction, namely the lightweight panels fencing with filler cell type.

The closest known is a panel that includes a harness in the form of a frame, a plate and fill units.

The disadvantage of this panel that uses paper honeycomb on the basis of the foil which does not have sufficient bearing capacity, which limits the scope pane.

The purpose of the invention increase the efficiency of the panel at design load, reduce material consumption.

This is achieved by the fact that the panel, including tying in the form of a frame, the plate has a fill units in the form of bars with a ratio of length to sirih stars to form between them rhomboid or parallelogram shapes. At the three-pointed stars can be located on one straight line in each tier. The ends of the bars in contact with the plate, is connected in Kadoma series with each other and with the plate of the reinforcing element. The reinforcing element is designed in the form of strips, bent to the plate and fill units, planes which form an angle profile.

In Fig. 1 shows the proposed panel, the cross section of Fig.2 panel with the centers of the stars on one straight line in the circle, the cross section of Fig. 3 the connection node of the covering sheet to fill by using a reinforcing element in the form of a strip.

The panel includes a frame 1, sheets 2 skin, 3 bars with a length to width ratio of 15-25, forming a three-beam star, forming, in turn, rhomboid or parallelogram shape. The ends of the bars 3 connected to the plate of the reinforcing element in the form of a strip 4 with bent ends forming an angle profile.

This embodiment of the panel allows, in addition, to improve manufacturability of its Assembly, using the bar as the mounting of the fastening elements filling up the installation sheets.

1. The PANEL, including tying in the form of a frame, the panels are to a width of 15 to 25, forming a three-beam star, the ends of the rays which in each layer are in contact with the ends of the beams adjacent stars to form between them rhomboid or parallelogram shapes.

2. The panel p. 1, characterized in that the centers of the three-pointed star in each layer are arranged on one straight line.

3. The panel on the PP.1 and 2, characterized in that the ends of the bars in contact with the plate, are connected in each row with each other and with the plate of the reinforcing element.

4. Panel on p. 3, characterized in that the reinforcing element is designed in the form of strips, bent to the plate and to fill the planes which form an angle profile.

FIELD: aircraft industry; production of light volume fillers made out of the laminated materials.

SUBSTANCE: the invention is pertaining to production of light volume fillers made out of the laminated materials for sandwich panels and may be used in production of aircrafts. The filler represents a volumetric construction in the form of a base made out of a polymeric paper and a binding substance applied on its both sides. The paper base of the filler is perforated, and due to that the binding substance layer depth is reduced, and the value of reduction, the number of pinholes of the perforation and their diameter meet the conditions of theformula: where: nholes - a quantity of holes of perforation;dholes - diameter of the holes, ▵b - reduction of the binding substance layer depth, F - the area of the surface of the filler, δp - the base layer depth, ρp - density of the paper base material, ρb - density of the binding substance. The given engineering solution improves profitability of an aircraft.

EFFECT: the invention ensures improved profitability of an aircraft.
