Description

PUBLIC VEHICLE FLOOR DESIGN (OPTIONS)

A group of utility models relates to transport, and relates to the design of the floor of the passenger compartment. A predominantly useful model will find application in the passenger compartment of subway cars.

The first version of the utility model relates to the floor structure of a wagon under construction or a wagon undergoing major repairs.

The second variant of the utility model relates to the design of the floor of the car, which is under current repair.

Well-known floor constructions of public vehicles, in which the top layer of multilayer flooring is used linoleum on a jute basis. The insufficient abrasion resistance of the linoleum used leads to the destruction of the coating.

As a prototype of a utility model, the subway car floor design, described in the album “Metro 501 Album of the Plant named after Egorova I.E., drawing 508.05.05001, floor cladding - Leningrad, 1970. The design includes a bearing base made of corrugated metal sheet material and flooring. The flooring has several layers, including two layers of asbestos cardboard, on top of which sheets of plywood are laid. The plywood is laid along the length of the passenger compartment in two rows. The longitudinal joint between the rows of sheets of plywood is located in the aisle between the rows of seats for passengers. The top layer of the flooring is made of jute-based linoleum. As indicated above, jute-based linoleum does not have high abrasion resistance. IN

under conditions of intensive use, the service life of such a coating does not exceed 3-5 years.

Replacing the coating leads to high costs, because the wagon is decommissioned, and during the overhaul, dismantling of the seats is required.

The utility model is based on the task of increasing the service life of the floor structure.

The task in the first embodiment of the utility model is solved by the fact that the floor design of the passenger compartment of a public vehicle includes a supporting base made of corrugated metal sheet material, and a deck having a layer of fireproof heat and sound insulation material, for example, sheets of asbestos cardboard on which the sheets are located plywood. In this case, the top layer of the flooring is linoleum. New features that distinguish the utility model from the prototype is that the sheets of plywood are laid along the length of the passenger compartment in three rows, the width of the sheets of the outermost rows is selected so that the joint with the sheets of the central row does not protrude beyond the projection onto the floor of the passenger seats, and is commensurate with the transverse size of the seat, and commercial linoleum is used as linoleum, the composition of which is based on polyvinyl chloride.

The width of the sheets of the extreme rows of plywood is 0.45-0.55 m.

The task in the second embodiment of the utility model is solved by the fact that the floor design of the passenger compartment of a public vehicle includes a supporting base made of corrugated metal sheet material and a deck having a layer of fire-retardant and heat and sound insulating material, for example, asbestos cardboard sheets on which sheets of plywood. On top of the plywood, linoleum is laid on

jute base. New challenges distinguishing a utility model from a prototype is that linoleum on a jute base in the area of areas with a defect in the working layer is treated with putty material to ensure surface alignment, and commercial linoleum is additionally laid on top of it, the composition of which is based on polyvinyl chloride.

In more detail, the essence of the utility model is disclosed in an example of a subway car floor structure and is illustrated by drawings, in which: Figure 1 is a transverse section through the structure. FIG. 2 is a diagram of the cutting and stacking of plywood sheets.

The design incorporates a bearing base 1 mounted on the carriage frame made of metal sheet material. The base 1 has a longitudinally oriented corrugations of a trapezoidal section. On the base 1, a flooring is laid, including a layer of heat and sound insulating material, for example, asbestos cardboard 2, on top of which sheets of plywood 3 are laid with a thickness of 10 mm. Sheets of plywood and asbestos cardboard are fixed on the base 1 using self-tapping screws 4 with countersunk head.

In the first version of the utility model, plywood sheets have a new, compared to traditional, cutting and are laid along the length of the cabin in three rows 5,6,7. The width of the sheets of the extreme rows 5.7 (rows 5 and 7 go along the side walls of the car) is selected from the condition of the location of the joints 8 between the rows of sheets outside the zone of passage of passengers. Taking into account the fact that the seat bases (the so-called lockers) have a smaller lateral dimension than the lateral dimension of the seats (i.e. the seat itself stands for

3 base), - the width of the sheets of the extreme rows is chosen smaller than

the transverse dimension of the actual seat, so the joints with the sheets of the central row do not protrude beyond the projection onto the floor of the passenger seats.

Joints between plywood sheets in a row and between rows are plastered with adhesive materials, for example, PVA glue with a filler (concrete equalizer Concrete, etc.) This provides additional fixation of the edges of the sheets. The joints are polished. Linoleum 9 is laid on top of plywood sheets. Commercial, for example, homogeneous linoleum made on the basis of polyvinyl chloride is used as linoleum.

Commercial homogeneous linoleum has a uniform structure throughout the thickness (1.2 - 2.0 mm). Inexpensive and ergonomic, it has exceptional abrasion resistance. As such linoleum, it is recommended to use a coating sold under the trademark Polyflor Voyager, in which particles of quartz, silicon carbide, aluminum oxide are introduced into the mass of polyvinyl chloride, which provide anti-slip properties of the material.

However, commercial homogeneous linoleum requires careful preparation of the base surface, since its low elasticity can contribute to destruction on uneven surfaces. Vulnerable areas are the joints of plywood sheets. Optimized sheet cutting

plywood brings joint zones beyond the area of most active use. Additional processing of joints also allows you to make the surface as flat and monolithic as possible.

In the second embodiment of the utility model (not shown in the Figures), the floor structure is formed in the process of its current repair based on already

existing gender. As in the first embodiment, a flooring is laid on the base 1, including a layer of fire-retardant material, for example asbestos cardboard 2, on top of which sheets of plywood 3 are laid 10 mm thick. Cutting plywood sheets saved. Sheets of plywood and asbestos cardboard are fixed on the base 1 using self-tapping screws 4 with countersunk head.

laid linoleum on a jute base. On the floor to be repaired, linoleum on a jute base has defective areas with a crushed upper layer. Such areas are treated with puttying material and ground to ensure smooth surface. On top of the repaired linoleum, a commercial, preferably homogeneous linoleum described above is additionally laid.

The floor structure and materials used can withstand significant loads associated with the daily active movement of a large number of passengers. Floor service life of at least 15 years.

The first embodiment of the utility model can also find application in the floor design of the passenger compartment of a public vehicle, in which, like in a subway car, seats for passengers are installed along the walls of the car.

The second variant of the utility model may find application in the repair of the floor of the passenger compartment of a public vehicle.
