Description

The claimed technical solution relates to transport engineering, in particular to the fastening of transverse partitions or other intermediate walls to the sidewall of a railway carriage.

In passenger cars, a common way of forming separate compartments is to install transverse partitions between the floor and the ceiling of the car with fastening to the side wall of the car, in particular to the side wall with windows.

A device is known for connecting the transverse partition with the uprights of the side wall of the vehicle (USSR author's certificate No. 1491756, B61D 17/00, application form 13.07.1987, publ. 07.07.1989 Bull. No. 25), containing one above another, the frame rods, each made with a transverse groove in the middle, and an insertable trough-shaped profile reinforcing the transverse partition connected to the transverse grooves of the rods by mutual fixation elements.

A feature of the assembly of the known device is that reinforcing profiles are inserted into the transverse grooves of the rods together with the partition, i.e. after they are fixed on the edges of the partitions.

Such an assembly is used in the production of cars of a modular block design with a removable bearing roof, in which partitions can be installed in the vertical grooves of the carcass rods only with the car roof removed.

In this design, the trough-like structure supporting the transverse partition reinforcing the cross-section requires complex fitting work during assembly and does not provide the sidewall with the required thermal insulation properties.

The closest technical solution (adopted as a prototype) is the fastening of the partition to the side wall of the rail mobile unit (GDR patent No. 218051, B61D 17/00, declared 08.08.1983, published. 01.30.1985), containing mounted on the bearing elements of the sidewall U-shaped fixing chute, in which the edge part of the partition is placed with a gap, on the end of which there is an elastic compensating and decorative profile formed with lateral supporting shoulders, between which, on the one hand, there is an elastic “dent” zone, and on the other st Orons, there are decorative trims adjacent one edge to the car lining, and the other to the partition. The elastic compensating and decorative profile during assembly is attached to the end of the partition with brackets. The partition is mounted using corner profile elements on the side wall.

In this design, the presence of a large number of visible fasteners complicates the fastening of the transverse partition to the sidewall of the car and worsens the appearance of the partition, and the presence of gaps and technological gaps between the side support shoulders and the shelves of the U-shaped fixing chute does not ensure the tightness of the connection between the partition and sidewall, which leads to heat loss in the car.

The objective of the proposal is to simplify the design of mounting and mounting the transverse partition to the sidewall of the car, improving the appearance of the car and its heat-insulating properties.

For this, the fastening of the transverse partition to the sidewall of the car contains a trough-shaped profile fixed to the supporting elements of the side wall, in which the edge part of the partition is placed with a gap, a decorative strip with a shoulder, part of which is placed in the said gap, adjoining one of its edges to the lining of the car and the other to the partition fasteners. What is new is that the said part of the shoulder is made in the form of a longitudinal protrusion limited by a stop interacting with the side of the trough-shaped profile and pressed by the profile shelf directly to the partition wall by a fastening element in the form of a coupling bolt.

In addition, the decorative strip and the shoulder can be made as a single unit of slow-burning plastic.

The decorative strip and the shoulder can have a locking connection between themselves, where the decorative strip is made with a serrated crest, and the emphasis of the shoulder - with its corresponding serrated groove. In this case, the decorative strip is made of slow-burning plastic or rubber, and the shoulder is made of extruded metal or hard plastic.

The width of the decorative strip exceeds the width of the side of the trough-shaped profile.

Horizontal grooves are made under the sidewall load-bearing elements on the edge parts of the partition and the shoulder, ensuring their connection with the profile shelves, on which holes are made for the fastening elements, and cut-outs containing these elements are made in the partition and on the shoulder.

A hole is made on the longitudinal protrusion of the shoulder, and a plate hook is made on the shelf of the trough-like profile, interacting with said hole.

The longitudinal protrusion of the shoulder can be made gear, and then the above lamellar engagement interacts with it.

The technical result is expressed in the following.

The implementation of the part of the shoulder in the form of a longitudinal protrusion, limited by a stop interacting with the side of the trough profile, ensures the accuracy of installing the partition with minimal time, which simplifies the installation of the transverse partition to the side of the car and improves the heat-insulating properties of the car as a whole due to the tightness of the connection between the partition and the trough .

Pressing the profile shelf directly onto the partition wall of the longitudinal shoulder protrusion by the fastening element in the form of a coupling bolt simplifies the design and assembly of the fastening of the transverse partition to the side of the car, and also improves the appearance of the partition.

The implementation of the fastening elements in the form of coupling bolts allows for a rigid connection of the transverse partition to the sidewall, preventing its displacement in the longitudinal direction, and to facilitate the replacement of the transverse partition if necessary.

The fastening of the transverse partition 1 to the sidewall 2 of the car contains a trough-shaped profile 4 fixed to the supporting elements 3 of the sidewall, in which the edge part 6 (11, 12) of the partition 1, a decorative strip 7 with a shoulder, is placed with a gap 5 (Figs. 3-10) 8 adjacent to one of its edges 9 to the lining 10 of the car, and the other edge 11 to the partition 1, fastening elements 12. A part of the shoulder 8 is placed in the gap 5 and is made in the form of a longitudinal protrusion 13, limited by an emphasis 15 interacting with the side 14 of the trough-like profile 4. The longitudinal protrusion 13 is pressed along the can 16 of the profile 4 directly to the wall 17 of the partition 1 by the fastening element 12, made in the form of a coupling bolt (Fig.3, 4).

Decorative strip 7 and the shoulder 8 can be made as a single unit (figure 3, 5, 7, 9) of slow-burning plastic with variable hardness.

The decorative strip 7 and the shoulder 8 can have a locking connection between each other (Figs. 4, 6, 8, 10), where the decorative strip 7 is made with a toothed ridge 18, and the emphasis 15 of the shoulder 8 is made with a corresponding toothed ridge 18 with a toothed groove 19. B in this case, the decorative strip 7 is made of flame-retardant plastic or rubber, and the shoulder 8 is made of extruded metal or hard plastic.

The width of the decorative strip 7 exceeds the width of the bead 14 of the trough-like profile 4. The lining 10 is mounted directly on the supporting elements 3. This creates a free space 20 between the decorative strip 7 and the side 14 of the profile 4, which can be used to place, for example, channels for electrical wiring (not shown).

Under the supporting elements 3 of the sidewall 2 on the edge parts 6, 21 (Figs. 11-14), respectively, of the partition 1 and the shoulder 8, horizontal grooves 22 are made, which ensure their connection with the shelves 16 of the profile 4, on which holes 23 are made for the fastening elements 12, and in the partition 1 and on the shoulder 8 are respectively made cutouts 24, 25 or holes (not shown) containing the elements 12.

Bearing elements 3 are runs made of a material with low thermal conductivity (slow-burning plywood, fiberglass, plastic, etc.), the ends of which are rigidly fixed in the landing elements 26 (11, 12) of the sidewall frame 2.

A hole 27 is made on the longitudinal protrusion 13 of the shoulder 8 (Figs. 7, 8), and on the flange 16 of the trough-like profile 4 there is a plate hook 28 interacting with the hole 27.

The longitudinal protrusion 13 of the shoulder 8 can be made gear (Fig.9, 10). The plate hook 28 on the shelf 16 of the trough-like profile 4 in this case interacts with it.

Assembly is as follows.

The transverse partition 1 with the edge part 6 is introduced with a gap 5 into the sidewall 2 fixed on the runs 3 of the trough 4, while the runs 3 are included in the grooves 22 of the partition 1. The shoulder 8 is inserted with its longitudinal protrusion 13 into the gap 5 between the shelf 16 of the profile 4 and the wall 17 partitions from one or both sides all the way into the side 14 of the trough-like profile 4, while the runs 3 are included in the grooves 22 of the shoulder 8. If there is a trough-shaped profile 4 of the plate hook 28 on the shelf 16, the shoulder 8 is automatically fixed in the hole 27 (Fig. 7 , 8). In the case of the longitudinal protrusion 13 of the shoulder 8 toothed (Fig.9, 10), the plate hook 28 interacts with it. After that, in the holes 23 on the shelves 16 and in the cutouts 24 and 25, respectively, of the partition 1 and the shoulder 8 are inserted tie rods 12, which rigidly fix the profile 4, the shoulder 8 and the partition 1 between themselves. Then, the end 9 of the decorative strip 7 is bent to the side and fixed on the runs 3, the lining 10 by means of fasteners 29 (Fig.3, 5, 7, 9). If the decorative strip 7 and the shoulder 8 have a locking connection between each other (Figs. 4, 6, 8, 10), then the lining 10 is fixed before the installation of the decorative strip 7, and then the toothed comb 18 of the decorative strip 7 is latched into the toothed groove 19 of the shoulder 8.

Dismantling is carried out in the reverse order.
