The invention relates to sudost P) eik1, to elements of floating structures consisting of separate pontoons connected in a single whole by means of locking devices.

The invention reinforces the design and expands the operational capabilities of the locking device by allowing the device to receive the device of the bomber blue / yellow load.

FIG. 1 depicts an exematical locking device, side view; on ft. 2 section A .4 in FIG. 1; in fig. 3 section B B and FIG. one.

The locking device is nos () it from the beveled plates I, attached to the sides of the joined pontoons at the deck and the bottom, with pad linings 2 with grooves for the plugs 1 and c) there are bolt holes 3 for the deck linings 4 with grooves under the center, 1 lasters 1 and with dug holes under the bo 11Y 3, as well as bo, 1 t 3 d. Shaking of the pads 2 with the pads 4. K) also in the back of the device 1}) en screw 5 moving along the deck, 1b along the thread in plate 6, with a shank, skol1 — this is the one that is used for the alternate n, Austria. 7. Plates () and 7 are closed1, | on the pontoon on one side of the joint. On the Nongon, on the other hand, one hundred of the joints is closed, four pins, 1 st type, 8) answer) under the Vipt 5 shank. Llpn pontoons n, tastips 7, the arrival of g in the trans: uds: close contact with the t.tasgins. The screw shank 5 is operated according to a favorable scheme and a clean cut. 11i) Inu p, pump 1, and also d; 1 pads 2 and 4 can be assigned, depending on o / kil; to the mih values of bending moments. on the lock.

Assembling the structure with 11red, tag.1,1m .ia.i-kovoy device.m, P1 e hect.) P1pm way.

(the crooked pontoon is installed on the water pipe to the earlier assembly) of the coo | iy-zhepi part, 1 is the closure) (which are from the bottom of the neck, the panes 2, the pa, the double back of the four, and partially turned out of 2 bo. Tto, 3 pre-hinged on the pongs of the assembled part of the structure. Then bo, tty, i then so that 1 (sk; | k) chit 1) self 11 | and) voluntary removal of the pontoon from the assembled part of ), and the shanks of the screws 5 are screwed into the holes of the plates 8 so as to prevent movement of the docked pontoon in the joint plane. Then the bolts 3 are finally fastened with the lining 2 with the lining 4 and the joint acquires full strength. In a structure with bolts 3 tightened and screws 5, the elements of the locking device (lining 2 and 4 perceive only the bending moment, and the shanks of screws 5 only relieve force) are significantly easier, which leads to the achievement of the goal.

The locking device operates as follows.

The forces acting on the structures at any inter-joint junction cause bending moment, longitudinal and transverse forces. The moment and longitudinal force tends to bring the plates 1 together or to remove them from one another, because they are prevented by compressive stresses in the plates 1 or the protrusions of the plates 2 and 4. The shear force tends to move the pontoons relative to one another in the plane of the junction (plates 7 relative to the plates 8) prevented by the shanks

screws 5 inserted into the holes in the plates 7

and 8.

Claims (1)

Invention Formula 0 A device for connecting ponts of prefabricated floating structures, comprising skids, located on pontoons at their butt-off ends, and closure elements made of bolts and lining them with recesses for skospepnye stops, characterized in that , from 5 ts.) to enhance the design and expand the operational capabilities of the locking device by ensuring that the device can accept large power loads; the full stops are made of adjacent plates with external bevels and edges, and the locking device is provided with connecting plates at the abutting ends of the pontoons, having pivot holes with a locking horizontal rods passing through them with screw screws of their linear alignment.
