    by means of struts 12 and 13, the length of which can be adjusted by means of a length adjustment mechanism, struts 14 and 15 and a locking device 16, which makes it possible to abruptly, reversibly shorten the connections. The lower parts 10 and 11 of the shields 3 and 4 can be connected by means of horizontal rods 17, which also have a locking device 18 together with an element for adjusting the length of the boom 17, similar to the locking device 16 of the struts 12 and 13.
    To remove the formwork in two separate sections, racks 19 and 20 are commonly used, which hold the free edges of the horizontal shields 5 and 6 and are installed on the ground to prevent the formwork from falling when the connecting element 9 is disconnected. The formwork can be adjusted in height by means of lifting devices of the lower parts 10 and 11 and they can be moved in the longitudinal direction due to the rollers located on the level of the lower parts 10 and 11.
    The connecting element 9 consists of two plates 21 and 22, which are welded under the free edges 7 and 8 of shields 5 and 6. Each plate 21 and 22 has a plug 23 and 24 in which is a key lock 25 having two arms 26 and 27 , provided at the ends with grippers 28 and 29, In addition, the plates 21 and 22 have, on opposite forks 23 and 24, forks 30 and 31, in which the levers 32 and 33 enter, on the latter are figured plates 34 and 35 attached with screws, have plugs 36 and 37 for engaging around grippers 28 and 29. The figured plates 34 and 35 are rigid when Replicas to lever 32 and 33 respectively, with screws 38–41 ”. Bandages 38 and 40 are usually installed in a circular hole in figured plates 34 and 35, while screws 39 and 41 are installed in elongated slots 42 and 43 in figured plates 34 and 35 and in the thread made in the levers 32 and 33. Such a device makes it possible to slightly change the position of the forks 36 and 37 and the possibility of adjustment. The key retainer 25 is secured in the plug 24 by means of a finger 44.
    Since the plates 21 and 22 are strictly identical and are located symmetrically under each of the free edges 7 and 8 and the shroud 44-47 can be removable, the position of the key lock 25 and the levers 35 and 34 can be reversed
    The ends 48 of the levers 35 and 34 with respect to the same section are connected to each other by means of a rod held by a nut 50. Thus, the maneuvering of two slugs with more levers 35 and 34 can be performed simultaneously.
    Plates 21 and 22 have holes 49, 51 and 52, whose axes are parallel. The holes 51 and 52 are designed to fit in them a section connector bar 53, which is located along the entire length of one of the free edges 7. The rod 53 can also be placed in the holes 52 of the plate 22 relative to the free edge 8.
    At the level of each plate 21, the rod 53 has a strap 54 containing a sleeve 55 into which the rod 53 is installed and which is connected to the rod by means of a connecting pin 56. Thus, all the slats 54 located on the same rod 53 can simultaneously perform one and the same movement, controlled by a rod 53, which can be both displaced in the longitudinal direction and rotated around its axis. In addition, the strap 54 has a finger 57, Attached to the strap 54 by means of a nut 58. Finger 57 can replace the finger 45, securing the latch 25 in the fork 24. The end 59 of the finger 57 has a conical shape to facilitate its insertion into the corresponding holes of the latch fork 23 25. For this purpose, for the conical pin 57, the corresponding conical holes 60 and 61 are made in the plate 21 and the hole 62 in the retainer 25. Similarly, the conical holes 63 and 64 are made in the plate 22, and the conical hole 65 is in the retainer 25.
    The connector bars 53 actuate the strips 54 of the two horizontal shields 5 and 6 by simultaneously connecting or disconnecting the fingers 57, which connect the key lock 25 with the plates 21 and 22.
    The connection of the horizontal 5 and vertical 3 shields is carried out

    through the unit 66, the forming surface 67 of the horizontal shield 5 is separated from the forming surface
    68 of the vertical shield 3 through connection 69, wherein the two forming surfaces 67 and 68 are strictly aligned with each other by means of two groups of guides welded respectively to the shield 5 and the surface 67, as well as to the shield 3 and the surface 68. The shield 5 is made rigid by a group of segments 70 in the form of omega, while the shields 3 are given rigidity by means of a group of segments 71 in the form of omega. Angled section 72 is welded.
    the omega-shaped segments 70 of the shield 5, while the other angled segment 73 is welded to the omega-shaped segments 71 of the vertical shield 3. The two segments 72 and 73 reinforce the connection between the shields 3 and 5, which are connected on this level with bolt 74 extending into holes 75 and 76 of segments 73 and 72, respectively. The elastic seal of the bolt 74 is provided with a pair of disc springs or 77 washers like the Velleville washers. The coincidence of the two forming prvernos-. Tei 67 and 68 regarding the connection
    69 is provided with two groups of welded guide elements 78 and 79 on the surface of segments 72 and 73 oriented in the direction to the struts 12. The guide elements 78 and 79 are made in the form of small rods that engage with a part of the free vertex located between the horizontal and parts of segments 72 and 73, i.e. guiding element 78 is applicable to both horizontal, ak and vertical parts of segment 72. Thus, any relative horizontal movement of the mezvdu plates 3 and 5 is prevented. The same result is obtained by replacing the welded guide elements 78 and 79 with gear elements 80 and 81 in the form of a rack, the teeth of which are engaged with each other.
    The struts 12 and 13 are divided into two frames 82 and 83 pivotally connected along the axis 84, parallel to each other at some distance between the axes of the end joints of the struts 12 and 13, located at the bottom of the vertical shields 3 and 4 and adjacent to the horizontal shields 5 and 6. The two frames 82 and 83 can be held coincident by the locking device 16.
    The frame 82 is formed by two parallel parts, slightly spaced from each other, between which the frame 83 can rotate. The two parts forming the frame 82 are kept separated from each other by means of a rigid ;, fixed axis .85 with which it can engage the pawl 86 turning around the axis 87. The pawl 86 of all the struts 12 or 13 with respect to the same section is connected by means of the connecting rod 88.
    The rod 17 is divided into two telescopic parts 89 and 90, which can be combined by means of a locking device 18, made as an element for adjusting the length of the compass rod 17, having a leg 91, pivotally mounted on the part 89 at the seat 92, and a leg 93, pivotally installed on part 90 of position 94. Two legs 91 and 93 are hinged at position 95. Telescopic part 90, which moves in the longitudinal direction inside telescopic part 89, has a stroke limited by the device formed by slot 96, cut through in the wall of the part 89 in which the gripping device 97, which is integrated, with the part 90 of the Foot 91 of the device 18, slides past the axis 92 by means of the lever 98 for maneuvering. FIG. 1 shows the device 18 with a maximum span, i.e. legs 91 and 93 are practically the same. To shorten the rod 17, the lever 98 must be raised so that the legs 91 and 93 form an angle with each other to transfer the axis 92 closer to the axis 94 and as a result
    Decking works in a way.
    When the formwork is installed in the working position, the key lock 25 connecting the plates 21 and 22 is rotated relative to the horizontal shields 5 and 6, which are connected to the vertical shields 3 and 4 struts
    12 and 13. When the shields 5 and 6 are at the same level, the key lock 25 is set so that the fingers 45 and 44 are also at the same level, so that the shoulder 27 can be positioned horizontally in order for the gripper 29 to go into the fork 37 of the shaped plate 34 of the locking lever 33. The gripper 100 automatically engages the fork 27 and when the lever 33 is slightly tilted and returned to the lower one (the direction by means of its weight, as well as by the weight of the rod, degree because the two side walls are vit 37 and directed substantially toward the axis. To complete this initial adjustment of matching between 5 and 6 at the beginning of the screws 38 and 39 may
    be detached to ensure the movable position of the figure plate 34 and the fork-37 until the shields,. 5 and 6 will not be exactly the same level; At this moment, screws 38 and 39 are the stopper of the vehicle.
    In order to open the connecting element 9, it is enough to raise the rod in order to raise the locking lever 33 relative to the same
    half of the body, this is done in order to detach the plugs 37 from the grippers 29. This operation must be carried out at the same time as the braces are shortened. When the claws 29 are disengaged, keyed, the latch 25 can turn and out of engagement with the plates 35 and 34. During this maneuver, the grip 28 of the shoulder 26 can
    This drive part 90 inside part 50 to engage in the plug 36 relative89. In the position of the maximum extension of the rod 17, the lever 98 is deprived of mobility relative to part 89 by any means, for example a ring or hook (not shown). In addition, as with the struts 12 and 13, the element for adjusting the length of the rod 17 is provided for precise adjustment by means of a screw mechanism 99.

    relative to the unlocking lever plate 35. When the formwork is in the open position, the shields 5 and 6 can be held at different levels by withdrawing the grippers 28 locked in the fork 36. Unlocking is achieved by simultaneously raising all the levers 32 by means of their rod so as to allow the rods to engage with the fork 36.

Unlocking is achieved by simultaneously raising all the levers 32 by means of their rod so as to allow the clamps 25 to rotate to the desired position.
    The maneuvering of the connecting elements 9 should be carried out simultaneously with the struts 12 and 13, which can be shortened i-she lengthened to a strictly predetermined value by forcing the frame
    S3 with respect to the frame 82 by means of 2 key clips 25. Last, by acting on the connector, besides, the hinge 88 is pivoted. The latter makes it possible on the plate 83 to activate all 44 by means of a finger simultaneously, which is fixed. dogs 86 and release them from separating sections 1 and 2 each of the clutches on axles 85. The weight connecting-15 from the Friend just enough to pull the rod makes it possible to hold 53 in the direction of the arrow 101 so that the dogs 86 on axes 85. It can be understood to cause it to slide in the holes that when the frame 83 is folded back and 51, and to separate the strips 54 from the plates downwards from the position where it is the same 21. This is done so that with the frame 82 it gives away all the struts, the reproach-20 is known to the fingers 57 from the holes 60 and 61 to a sufficient size, and from the plate 21, as well as from the openings to allow the horizontal shields of 62 key clamps 25.
    5 and 6 descend to the value needed to remove the formwork.
    When the branches of sections 1 and 2 are connected, the section connector bar 53 is pushed so that all the strips 54 move closer to the plates so that the fingers 57 are inserted into the holes 60 and 61 of the plates 21 into the holes
