HU176547B - Support plate for supporting ditches - Google Patents

Abstract

Damaged flat sheets are repared by prepf. a uniform repair area, and fitting and bonding to it a prepd. repair patch; both the repair area and the patch have grooves in their edge sections and the resultant space between them is filled with matl. which will transmit shear forces. The process is quick, effective and esp. suitable for container wall panels.

Description

FIELD OF THE INVENTION The present invention relates to a security plate for securing ditches comprising a front and a back cover plate, further comprising spacers connecting these covers and tubular reinforcements disposed thereon, extending therethrough and in communication with the spacers. This type of security sheet is already known, such as U.S. Patent No. 2,230,395. However, in these cases the storage of some of its items is significant. In addition, connecting the elements is relatively expensive. Finally, known security sheets are relatively heavy, with limited transport options.

SUMMARY OF THE INVENTION The object of the present invention is to provide an improved design compared to the known safety plates, which is advantageous in particular in terms of production costs, in addition to being lightweight, while maintaining the required strength.

According to the present invention, this is achieved by forming a topsheet 20 and spacers in one piece, namely in the form of a comb-like plate, whose projection ribs occupy the interior of the securing sheet and have edges to the opposite topsheet. welded.

In this construction, a sufficient two cover - optionally selected from two identical cover - positioned opposite each other and a welded sal ⁵ and 30 tubular reinforcing elements pass through the ribs themselves iámért. In this way, a relatively strong, but still lightweight securing sheet is provided, which can be filled with additional foam for reinforcing, which in turn can be further reinforced. In a preferred embodiment of the invention, the ribs of the topsheets are connected to the opposite topsheets by roll-welding.

In a further preferred embodiment, the ribs are provided with cutouts for transverse passage tubular reinforcements. These cuts are preferably formed as slits.

The invention will now be further exemplified. Embodiments of the invention will be described in greater detail by means of the following drawings, of which:

Figure 1 is a perspective view of a portion of the securing sheet;

Figure 2 is a vertical sectional view of an assembled safety plate.

Fig. 1 shows one side of the safety plate. It's comb-like. It consists of a split plate 1 having a plurality of horizontally protruding ribs 2, the height of which is selected so as to strike the inside of an identical or similar plate as shown in FIG.

In the ribs 2, coincident recesses 3 are provided for receiving tubes 4 extending vertically along the securing plate. These tubes 4 can be welded to the ribs 2. The cutouts 3 can also be formed as holes.

However, as shown in the drawing, the cutouts are preferably slit-shaped and made with a depth such that the tubes 4 are positioned or clamped in the center of the sheet.

As shown in Fig. 2, the locking plate can be formed from two completely identical top panels, which are offset by 180 °, with each rib forming the lower and upper edges. The pages can be bounded and locked in a manner known from the side, with vertical profile holders or the like.

The cavities 5 between the topsheets 1, as shown in Figure 2, may even be filled with foamed plastics, such as polyurethane, optionally reinforced.

Preferably, the opposed topsheets and ribs are connected by means of a relatively cost-effective, flat-roller line weld 6.

It is also possible to form a safety sheet in which only one cover plate is provided with ribs according to the invention while the other cover plate can be a smooth plate.
