Description

The railcar roofs made from thermolite, asbolite and other masses are made by molding in the appropriate formats: in the present invention, this roof is made of individual parts connected by bolts through the holes of the flanges located on the connected parts.

In the schematic drawing of FIG. 1 shows a side view of the car with the proposed roof; FIG. 2 is a longitudinal section of the form and the molded roof canopy; FIG. 3- the same top view; FIG. 4-longitudinal section of the form and the molded middle part of the roof; FIG. 5 is the same top view; FIG. 6 is a longitudinal section of the mold and part of the molded roof; ft, 1 is the same top view; FIG. 8-curves; FIG. 9-iron arc.

The peaks 7 (figs. 2, 3) of the wagon roof 1 (fig. 1) are molded using the appropriate forms 5 as separate parts, and the middle part 8 of the car roof (figs 4, 5) is molded either by means of form 4 as a whole or Using forms 5 (figs. 6, 7) -from individual parts 19, the connection of individual parts 7, 8 or 19 is made by bolts through the holes in the flanges 20, with the iron arches 21 used to increase rigidity between them.

(Fig. 9), provided with holes 11 for the passage of bolts.

Forming is done by stuffing asbolite, thermolite and other masses onto forms, followed by tamping the mass and cutting the surface on pattern 6 (Fig. 8): the forms are equipped with a flange 14 designed to form an inward bend 2 on individual parts of the roof, connect the roof with the car body. In the manufacture of the roof for a tram or other similar car, grooves 9 are made on the roof surface, which serve to lay electrical wires. In the case of fabricating the middle part 8 of the roof entirely, it is provided with ribs 10 for greater rigidity.

The subject of the natent.

A car roof made of thermolite, asbolite and other masses by molding (mass stuffing) in appropriate forms, characterized in that it is composed of separate, molded parts 7, 8 or 19 (Fig.) Connected by bolts through the holes flanges 80, between which, for greater rigidity, iron arcs 21 with holes for the passage of bolts are laid.
