Description

The invention relates to road construction works and can be used in the construction of gauge coatings of reinforced concrete slabs. The known structure of the butt joint of a combined-pavement pavement, in which at the abutting ends of the plates are made loops and hooks offset to the supporting surface | 1 The disadvantage of such a construction is the negligible 1a magnitude of the transmitted bending moment, as well as the difficulty of replacing worn plates during operation; The closest to the invention according to the technical essence and to the end result is a butt joining of a collapsible road surface made of reinforced concrete slabs, including nests made at the ends of the joined plates and pins located in them with thickening in the end part. 23 Disadvantages of this Structures are the difficulty of interconnecting the slabs with each other and are limited to the possibility of transmitting a bending moment from slab to slab. The purpose of the invention is to simplify the cooperation of the slabs between themselves and ensure the transfer of the bending moment from the slab to the slab. The goal is achieved by the fact that in a butt joint of a assembled pavement of an IZ reinforced concrete slab, including nests made at the ends of the abutting slabs and located in them with a thickening at the end. Each of the sockets, plugs and sockets are located skew-symmetrical on opposite edge areas of the plates' ends, with each socket open from the side surface of the plate and has a horizontal 1 562 depression that extends to the middle of the plate, and a pad is installed between the adjacent ends of the plates. In addition, the length of the tongue protruding beyond the end of the plate may exceed the depth of the socket by the thickness of the non-wrinkle pad. FIG. 1 is a side view of the slab coating; in fig. 2 - the same plan; in fig. 3 is a view A of FIG. 2 (stove); in fig. 4 and 5 - the implementation of grooves and shtyrey options; in fig. 6 and 7 — the butt joint of FIG. 4 and 5, side view. The butt joint is placed on the edge areas of the plates 1, each of the ends being provided with a socket 2 and a tongue 3, made of a ductile and durable material, such as steel, and attached to the bottom reinforcement of the plate, and the socket 2 is open from the side of the plate and is horizontally oriented and has extension to the middle of the slab, and the bottleneck of the socket is oriented toward the end of the slab and may have a bevel in the extreme part shown in FIG. 3 dotted line. In the case of a body that has a pin of greater size than the thickness of the groove narrowing, an infallible or resilient gasket 4 is inserted between the adjacent ends of the plates, for example, a board section with a thickness equal to the difference in the lengths of the body of the pin and the width of the tapered portion of the socket. The connection of the plates in the coating of the core is realized by the simultaneous insertion of the plugs into the adjacent grooves and with the lack of subsequent laying of the gasket between the plates. Such a connection, when performing symmetry-shaped sanding of the shtyry, excludes the deformation of the shtyry under the impact of a given load from the indicated factor. In this case, the joint perceives and transmits a bending moment to the adjacent slab.

Claims (2)

1. Butt joint of collapsible road coverings made of reinforced concrete slabs, including nests made at the ends of mating slabs and pins with a thickening in the end part, characterized in that, in order to simplify the connection of the slabs to each other and to ensure the transmission of bending moment from the slab on the plate, the pins and sockets are located obliquely on opposite edge sections of the ends of the plates, each socket being open from the side surface of the plate and has a horizontal extending towards the middle of the plate Noe recess and dy between the adjacent ends of the plates mounted crush proof gasket. 2. Connection by π. 1, distinguishing neck with the fact that the length of the part of the pin protruding beyond the end of the plate exceeds the depth of the socket by the thickness of the crush-resistant gasket.
