Abstract

The invention relates to mining, in particular to mechanized fasteners, and provides for a reduction in metal intensity and labor intensity of manufacture. The overlap includes the upper sheet 1 and the lower sheet 2 filled with the openings 3 and the support plates 4 placed above the openings 3 of the lower sheet. The outer surface 7 of each support 4 is filled with a spout. The part of the top sheet 1 located above the support is bent according to the shape of the surface of the support. Ribs are attached to sheet 1 and the ends of supports 4. The presence of ribs and supports gidroeek provides rigidity and eliminates the need for additional elements. Increase the rigidity of the structure. This reduces the metal structure. 4 W1. оэ 4 О СО

Description

113

The invention relates to mining, namely to mechanized crepe m cleaning faces.

The aim of the invention is to reduce the metal consumption and the laboriousness of manufacturing the overlapping of the lining section. In FIG. 1 shows the overlap of the general view; in fig. 2 - A - sections of the p supports of the girders and the middle of the ceiling, respectively

The overlap consists of the top sheet 1, the bottom sheet 2 with the hole. 3 under the racks and located between them above the holes of the bottom sheet of the rack supports 4, the lower ends 5 of which are bent horizontally and mounted on the bottom sheet 2. The ribs 6 are rigidly attached to the sheet 1 and the ends 5 of the supports 4. The outer surface 7 of each support is made convex and reinforced on the part 8 of the top sheet 1 above it, the support surface curved in shape. Thus, the overlap consists of 3 parts, obtained by stamping.

The inner box, in addition to the supports, also has profile ribs that provide rigidity to the structure. There is no need for transverse elements and various kerchiefs, which reduces the weight of the structure.

Formula inventions

The overlapping of the roof support section, including the upper and lower sheets, which have openings for the racks, has ribs rigidly attached to them and located between them above the lower sheet openings and pedestal supports whose lower ends are bent and arranged horizontally, characterized in that, in order to reduce metal intensity and labor intensity manufacturing, the curved ends of adjacent supports are mounted on the bottom sheet, the lower ends of the ribs are rigidly fixed to the ends of the supports, the outer surface of the support is made convex, and the part of the upper sheet is located above support, curved to shape the surfaces of the support.
