The invention relates to the construction and can be used in the construction of the exterior walls of multi-storey monolithic reinforced concrete buildings.

The purpose of the invention is to expand the technological capabilities of the formwork.

Figure J depicts the formwork from inside the building (working position), general view; 2 is the same, B1scj from the side, with partial cuts of the scaffolding and shields at the place of installation of the inserts for threading konkusgkh stjk and screw jacks in Fig.3 - the same, side view (transport position), with the formwork for the next capture; figure 4 - section aa in fig 1.

The formwork for erecting external walls, located in the working position on the frame 1 of a building of any height in its cells 2 and 3, the last of which is located 15T with cell 2 and has -yr-ie shaped window ledge 4, contains an outer shield 5 On the drug panel 5, complete with a cut-out along the window and (or) door opening, all the subassemblies and parts of the external wall forms with the openings are mounted. The formwork is equipped with lifting eyes 6 for transporting the device. In order to get not only flat 5 but also lable: front façade walls, which look like a stone, the outer seeker 5 is a structure that can be removed from the formwork, fragments of which can be made, for example, in the form of a widespread rectangular parallelepiped. facets of al - maz, stucco decorations, etc. in the architectural hompozitsky. The non-working surface of the outer shield 5 is fixedly attached to n0, tsmost 7, consisting of the upper 8 and lower 9 rus. Split 10-12 attached with suspensions, for example 13 for fixed fastening in case of transportation, are movably connected.

surface slope from top of the opening to the ceiling. The upper inner shield 12 forms the upper inner surface of the opening from the top of the opening to the ceiling. The inner 10 12 are installed along the contour of the opening and are connected to the outer shield 5, which allows, after opening, to unscrew the shields from inside the room to the street in order to transfer the formwork compactly to a new place. For fastening, the outer shield 5 is hingedly suspended on supporting brackets 16, and at the bottom is provided with fT clamps, with the ends alone hingedly suspended on the outer shield. The supports of the brackets 16 are connected, c. turn with threaded gantry 8th: escopic type.

The suspension of the outer shield 5 on the brackets Ib is made by a hinge or by means of a carriage 19, having the ability to move in the vertical direction through the screw 20 and in the horizontal direction through the screw 21, carried the outer shield 5. For the sake of impartiality The formwork adjustment is equipped with a plumb 22 and a level (not shown).

The outer shield 5 with the shields 10, П, 12, 14 and 15, fixed in par (5th position, is an aperture. Fig. And equipped with jacks 23 BbiMK, the ends of which, 1-turn supports 24 for abutting the formed and Toughness of the wall When dismantling.

On the bracket 16 there is a screw lanyard 25, hingedly connected with the upper inner shield

26, having the ability to rotate around the hinge 27 located on the outer shield 5 under the action of the B1 lash 25. The upper inner plate .26 forms the inner surface of the subwindow wall of the upper floor.

The shields 10 and 11 are suspended from the outer shield 5 on the hinge hinges x 28, and the shields 14 to 15 are suspended from the hinge loops x 2S to the shields 10 and 11, respectively. The shield 12 is suspended from the outer shield 5 at the hinge loops x 30. In the working position, the shields 10, 11, 12, 14 and 15 are fixed on the outer shield 5 with threaded cone strings 31.- To prevent the cement milk from leaking, the edges of the shields around the perimeter of contact with the frame of the building of the building is rubberized. To form the opening angles, inserts 32 and 33 are provided, fastened with wedges 34.

The external formwork works in the following way, with openings

To the frame 1 from the side of the external wall being erected in the building of the building, to its upper flight there are relatively each pair of cells 2 and 3 located above the other, where the window ledge 4 is located in the latter, the crane delivers the outer shield 5, holding it by the drawers 6 located in the feed zone 7 on its upper tier 8,

Previously, the lower tier 9 must be secured against spontaneous rotation of the shaft 10-12, for example, with the help of pendants 13. The boards 14 and 15 do not require special fixation, as they are suspended on boards 10 and 11, respectively.

Turning the boom of the crane, plant t bracket 16 into cell 2, and the outer shield 5 with the lower part set on the ledge 4 of the outer wall of the lower floor relative to the pre-selected cell 2 and catch on it, for example, with clamps 17. The inner cell 2 fixes the supporting brackets 16 at supporting the supports 18 by unscrewing them, directing their upper parts to the ceiling. Moving the outer shield 5 with the carriage 19 by rotating the vertical adjustment screw 20, exposes the outer shield to the design position in height. Clamps are poured over} 7. The outer shield 5 is tilted by rotating the screw 21 of the horizontal adjustment of the carriage 19 to the position parallel to the plumb 22, controlling the correctness of the leveling. The hinged fastening of one of the clamps 17 provides, under the force of a forced screw adjustment, with a carriage 19, turning the outer shield 5 without unlocking the clamps 17. Performing with all the shape of the opening, the outer surface forms the outer surface of the base from the bottom of the lower floor from the bottom of the upper floor. The jacks 23 are tightened until their supports 24 are flush with the corresponding working surfaces of the outer shield 5, the shields 10, П, 12, 14 and 15 on which

us these jacks. Then the working surface of the outer shield 5 and all shields are cleaned and lubricated. Screw in the lanyard screw 25, rotate the inner shield 26 around the hinge 27 and fix it to a distance from the working surface of the bulletin shield 5 equal to the thickness of the concrete. Then they close (alternately remove and install clamps 17) the shields IO and 11 by turning the hinges on hinges 28. Shut the boards 14 and I5 by turning on the hinges x 29 and shield 12 - on the hinges x 30. Working surfaces of the shields 10, 11, 12 , 14 and 15 are pushed away from the outer shield 5 by the thickness of the concrete, thereby providing an opening in the subsequent concreting, and fixed with threaded conical straps 31 by screwing the outer nuts of the threaded nuts onto their outer ends. In the clearance at the corners of the marks 10, 12, 14, and P, 12, 15 install inserts 32 and 33, force tionary locking the wedges 34 to the surfaces of the boards 10, 14 and 11,15, respectively, in the openings 5 between the outer shield and the shields 10, 1, 12, 14, the reinforcing elements are laid 15i26. The concrete worker, entering the upper rus 8, directs the expanded clay concrete and forms the window sill. For stripping, conical straps 3J are released from the threaded nuts and removed from the wall. 34 wedges and inserts 32 and 33 are knocked out. The threaded ends of the I7 clamps are unscrewed and, thanks to the hinged fastening of their opposite ends, tuck the claws 47 47 around their hinged hangers onto the floor of the lower rus 9 scaffolds 7. Turning the hinge loops x 29 opens shields 14 and 15, tearing shields from concrete help screwing in jacks 23; Turning the hinges on hinges x 28 opens shields 10 and 11, the separation of which from concrete helps screwing in jacks 23 located on these wires. By turning the hinge loops x 30, the shield 12 is opened, helping the jack 23 on the shield to detach from the concrete. On the lower rue 9 scaffolds 7, the ends of the shields 10 - 12 are fixed from spontaneous turning, for example, by means of suspensions 13, they fill holes in conical strut 31, usually maintenance of the formwork (cleaning.

lubrication) is performed on the working pick from the scaffolding or from the room. After this, the crane of the crane cable should be built up by the lugs 6 and the lifting cable should be pulled out. The lanyard screw 25 is unscrewed, the inner shield 26 is lifted by turning it around the hinge 27. Remove the outer shield 5 from the concrete surface by screwing the jacks 23 that are from on the outer shield, screw the screw 20 on the vertical adjustment and screw 2 on the horizontal adjustment of the carriage 19. Screw the props 18 into the inside of their telescopic cavities and fix them on the brackets 16. The outer shield 5 is raised to a height of 1 m with a crank. As a rule, it is sufficient for inserting the brackets 16 over the newly received window ledge. By turning the crane's boom, the arms 16 from cell 2, and supply the formwork of the external walls with openings to the next gripper.

The proposed formwork allows at one time, in contrast to the prototype, to concrete the wall surface from the bottom of the window or door opening of the underlying floor; as much as the upper and side surfaces of the formed opening, and at the same time the sill wall of the overlying floor for the next one is captured, which reduces labor costs for installation and disassembly opalzki ki and increases the convenience of its exploitation, i.e. not partly, but an external wall with an open aperture in the building under construction is completely frrmmed. In addition, simplification of the installation into a design position along the plumb line and the level of relief is achieved by the possibility of using a carriage that is moved by rotating screws of an independent vertical and horizontal stroke, which is inserted into the junction of the outer shield with support brackets. the use of the proposed formwork will reduce the cost of installation and disassembly by 10-15%. .
