The invention relates to crossing-bridge means, and more specifically to the pontoon (floating) bridge.

The famous floating bridge (see Pontoon pairs is in the longitudinal direction of the river links pairwise interconnected by means of joint nodes that are located on the rotary fairings, coastal units and tow-motor boats.

A disadvantage of the known floating bridge is that hampered the operation of the tow-motor boats together with the axle at high speeds, currents and wind waves.

Also known floating bridge (prototype, see the Pontoon Park PP-91// Technical description and operating instructions. 05341.360080.007. The first book, sheet 30, the second book, page 181. Fig. 183, JSC Vympel", Nizhny Novgorod, 1991), including stacked in the longitudinal direction of the river links that are pairwise connected by means of joint nodes that are located on the rotary fairings, engine parts, placed in pairs nasal pieces to each other between river sections, and coastal links.

The disadvantage of this floating bridge is that pairs located in the motor it links, in contrast to river sections are not interconnected. As a consequence, along the floating bridge, you cannot skip heavy machinery because of its lack of transverse strength.

The claimed invention is directed to solution of the problem p is e specified task is achieved by that floating bridge, including stacked in the longitudinal direction of the river links that are pairwise connected by means of joint nodes that are located on the rotary fairings, engine parts, placed in pairs nasal pieces to each other between river sections, and the coastal parts, motor parts are interconnected in the nasal parts in the area of the bottoms located on the sides removable hard rods with eyes at the ends, with one end of each rod with a longitudinal slot in the ring is installed on the same engine link on the pin transverse to the shank, and the other end of thrust with a round hole in the eyelet is installed on a different engine link on the pin with a vertical opening in which is placed a sliding pin.

The use of the claimed technical solution will increase the load capacity of pontoon bridge about two times by increasing its transverse strength.

The invention is illustrated by drawings, which depict: Fig.1 - floating bridge, side view; Fig.2 - the floating bridge plan; Fig.3 - section a-a in Fig.2; Fig.4 - section b-B in Fig.2; Fig.5 - section b-b of Fig.4; Fig.6 - section G-G in Fig.4.

Floating m the IRNA United the two middle and two outer pontoons. In the deck of the pontoons built roadway. On the transom medium pontoons installed butt joint 7, is made in the form of plugs with pins and eyelets through which the river links are connected in the bridge in the longitudinal direction. In the transverse direction of the river, the links are interconnected in pairs with joint nodes 8, located on rotated to the lower position of the fairing 9. The fairing is fixed in the lower position of the rods 10. In the upper position of the fairings are only floating bridge, assembled from a single row of links. Engine parts 3, 4 are placed in the bridge pairs nasal pieces to each other and are interconnected in the nasal parts in the area of the bottoms located on the sides removable hard rods 11 with the eyelets on the ends. One end of each rod with a longitudinal slot in the ring is installed on the same engine link on the pin 12 with a transverse shaft 13, and the other end of each rod with a round hole in the eyelet is installed on a different engine link on the pin 14, provided with a vertical bore in which is placed a sliding pin 15 and a handle 16. To the eye with a round hole welded plate 17, to which is attached the guide bushing 18 and 19. The eye with the longitudinal soedinennyh with him two outer pontoons. In the middle pontoon is placed engine and propulsion and steering complex, made for example in the form of jet propulsion, and on the extreme sides of the pontoons installed butt sites, similar in design junction nodes on the transom river links. In the deck of the pontoons motor link embedded roadway. Each pair of motor units placed in the floating bridge across a certain number of twin river links. At the end of the floating bridge installed onshore links. Coastal link differs from river level wedge shape and the presence of joint nodes on only one river, the transom. By land, river, motor and coastal parts are transported on a car when folded.

The proposed device operates as follows. River, motor and coastal links unloaded from cars to water. When this river and coastal links automatically open on the water, and the motor units open directly on the car before unloading. Next river links connect pairs to each other via a joint 8 nodes located on the swivel deflectors 9. Simultaneously connect pairs together in the nasal parts in the area of the bottoms located on bertaut along the sides of each hard thrust 11, holding it by the handle 16 and 20. Next, let transverse shaft 13 through the longitudinal slot in the eyes and set her on pin 12 (the position of the lugs shown in Fig. 5 in phantom lines). Then move the rod along the side of the adjacent side of the motor element to the stop pin 12 in the wall of the slot, put another ring on the pin 14 and lower retractable pin 15 from the extreme upper position (shown in Fig. 4 in phantom lines) down before entering it into the vertical hole of the pin 14. The pin 15 when lowering moves in guides 18 and 19. United pairwise river links join together in the longitudinal direction using a butt joint 7. After a certain number of twin river links placed one pair of motor units. At the ends of the gathered ribbon bridge set coastal links. The floating bridge is dismantled in the reverse order of Assembly. For this axle disconnect on the links, put them and upload to the car.

Floating bridge, including stacked in the longitudinal direction of the river links that are pairwise connected by means of joint nodes that are located on the rotary fairings, engine parts, placed in pairs nya interconnected in the nasal parts in the area of the bottoms located on the sides removable hard rods with eyes at the ends, one end of each rod with a longitudinal slot in the ring is installed on the same engine link on the pin transverse to the shank, and the other motor level on the pin with a vertical opening in which is placed a sliding pin.
