Изобретение относитс к области дорожного строительства и может быть использовано во всех отрасл х народного хоз йства дл строительства колейных переносных покрытий временного типа.The invention relates to the field of road construction and can be used in all sectors of the national economy for the construction of temporary-type gauge portable coatings.

Известно сборно-разборное колейное дорожное покрытие, состо щее из плит различной длины, соедин емых между собой стыковым соединение.м посредством паза и выступа 1.A collapsible track-road pavement is known, consisting of plates of various lengths, joined together by a butt joint m by means of a groove and a protrusion 1.

Наиболее близким к предложенному изобретению вл етс сборно-разборное колейкое покрытие, включающее составленные из брусьев плиты, щарнирно соединенные между собой посредством П-образных кронштейнов с отверсти ми, в которые входит крепежный стержень 2.The closest to the proposed invention is a collapsible rugged cover, comprising slabs made up of bars, pivotally interconnected by means of U-shaped brackets with openings that include the fastening rod 2.

Недостаток известных сборно-разборных колейных покрытий заключаетс в том, что покрытие при наличии таких стыковых соединений фиксируетс только в двух плоскост х, перпендикул рных оси движени транспорта, в результате чего возможно смещение плит по оси движени , так как нет ограничивающих элементов, удерживающих плиты относительно друг друга в продольном направлении . Кроме того, плиты, укладываемыеA disadvantage of the known collapsible gauge coatings is that the coating, in the presence of such butt joints, is fixed only in two planes perpendicular to the transport axis of the transport, as a result of which the plates can be displaced along the axis of movement, since there are no limiting elements that hold the plates relative to each other in the longitudinal direction. In addition, slabs stacked

в покрытие, должны подводитьс строго горизонтально , что не всегда возможно по услови м рельефа .местности и на практике требуетс тщательна планировка основани .the coating must be placed horizontally strictly, which is not always possible according to the conditions of the terrain and in practice careful planning of the base is required.

Цель изобретени - предотвращение взаи.много перемещени плит и облегчение укладки их в покрытие.The purpose of the invention is to prevent the mutual movement of the plates and facilitate their placement in the floor.

Цель достигаетс за счет того, что в сборно-разборном колейном покрытии, включающем составленные из брусьев плиты, шарнирно соединенные между собой, все плиты снабжены выступами, каждый из которых имеет зуб, и верхними и нижними упорами, причем выступы размещены на боковых поверхност х одного конца плиты, а верхние и нижние упоры - на боковых поверхност х другого конца плиты, при этом нижний упор примыкает к торцу плиты, а верхний с.мещен относительно нижнего упора и входит в зацепление с зубом выступа смежной плиты. Кроме того, плиты снабжены обоймами, к которым прикреплены выступы и упоры.The goal is achieved due to the fact that in a collapsible track covering, including slabs composed of bars, pivotally interconnected, all the plates are provided with protrusions, each of which has a tooth, and upper and lower stops, and the protrusions are placed on the lateral surfaces of one the end of the plate, and the upper and lower stops on the side surfaces of the other end of the plate, with the lower stop adjacent to the end of the plate, and the upper c is positioned relative to the lower stop and engages with the protrusion of the adjacent plate. In addition, the plates are equipped with clips to which the projections and stops are attached.

Claims

FIG. 1 shows the described coating in plan (an embodiment of the plate of transverse bars); in fig. 2 — node I in FIG. I; in fig. 3 is a view A of FIG. 2; in fig. 4 - described coating in plan (embodiment of the plate from the longitudinal bars and with the clips); in fig. 5 — node II in FIG. four; in fig. 6 is a view B in FIG. five; The coating includes plates 1, made of longitudinal or transverse bars. In the slab 1 of the coating, on the lateral faces of each of the plates, protrusions 2 with tooth 3 are mounted at one end, and at the other end, the upper 4 and lower 5 stops, which prevent the ends of the plates from moving in a vertical plane. The lower stops 5 are adjacent to the end of the plate, and the upper stops 4 are offset relative to the lower vertical to the height of the protrusions, and horizontally to the middle of the plate for a distance sufficient to insert the protrusions between the stops. The stops also prevent longitudinal displacement of the plates relative to each other, since the tooth 3 of each protrusion in the laid cover is set behind the upper stop 4. The projections 2 and the stops 4 and 5 can be attached to the holder 6, which are mounted on the lateral surface of the end sections of the plates. When assembling the coating, careful preparation of the base is not required, since the plates are connected to the wheel guide by inserting protrusions with a tooth between the stops in an inclined position, as shown by the dotted line in FIG. 1. After inserting the protrusions between the stops, the plate is lowered into the working position and is securely connected to the previously laid in the wheel rail. The absence of the possibility of plate displacement relative to the axis of movement of the rolling stock eliminates the possibility of wheel pipe breakdown, and, consequently, increases the performance of coatings. Claim 1. Collapsible track covering, comprising slabs made up of beams, pivotally connected to each other, characterized in that, in order to prevent the plates from moving and to place them in the floor, all the plates are provided with protrusions, each of which has a tooth, and upper and lower stops, with the protrusions placed on the side surfaces of one end of the plate, and the upper and lower stops on the side surfaces of the other end of the plate, while the lower stop adjacent to the end of the plate, and the upper offset no lower stop and engages the tooth adjacent protrusion plitts. 2. The coating according to claim 1, characterized in that the side surfaces of the end portions of the plates are provided with clips, and the protrusions and stops are attached to the clips.
