Description

The invention relates to the construction and is intended for the monolithic joints of prefabricated reinforced concrete structures.

The purpose of the invention is to reduce the time of installation and dismantling, ensuring the safety of work.

Figure 1 shows the formwork panel, a general view; figure 2 is the same, side view; on fig.Z and 4 - formwork device in the working position, front view and side view, respectively; figure 5 - locking device.

The device for monolithing the joints contains a sliding rack 1 with a length to the height of the floor, installed at an angle to the plane of the formwork panel and having a flat support in the lower part.

The rack 1 is connected to two decks of the formwork shield 2, in the upper part having a wedge-shaped broadening, with the help of arcuate levers 3 pivotally mounted on the decks. The latter are connected by a frame of sliding pipes with horizontal external pipes 4.

The rack 1 is connected to the frame with a pocket 5, and the end of the rack entering the pocket has a wedge shape. The arcuate arms 3 are connected to a frame of two horizontal and one vertical pipe 6, on which plate 7 is located, welded to the sliding pipe. The rack 1 with the pocket 5 is connected by means of a pin 8.

Horizontal sliding pipes 4 frames are connected to decks 2 (wooden and plastic) with a ring 9 mounted on the pipe and. fixed to deck 2.

The upper and lower ends of the arcuate levers 3 are hinged on the decks 2 and the plate 7 with the help of bolts with nuts 10.

On the vertical pipe 6 of the frame there is a locking device 11, made in the form of a hinge from a steel plate, with its arc extending from the hole in the pipe 6 located in front of the external vertical pipe 12, and the ends of the pipe 6 pressed to the internal parts of the hole.

The formwork device works as follows.

The formwork device is installed in the working position with the help of the rack 1, applying it to the column between the joints of the crossbars and the abutment the upper ends of the decks 2 into the gap between the column and the slab, while moving the vertical pipe 12c with the plate 7 upwards.

The arcuate arms 3 push the decks 2 horizontally and the latter move together with the horizontal extension pipes 4 along the frame 6 and stretch between the girders, after which the support 1 is wedged into the floor.

After filling with the concrete to be joined

Seats, vibrations and a set of concrete with the required strength are produced by spalling with the aid of a rack 1, which is removed from the floor with a floor and reduced in size. When the force on the rack 1. i.

moving it down, the vertical sliding pipe 12c plate 7 moves down, and the levers 3 carry along the decks 2, which move together with the horizontal sliding pipes 4 to the vertical

tube frame 6.

After removing the formwork device, the locking device 11 locks the movement of the pipe 12 along the frame 6 and thereby keeps the decks 2 from fully opening.

Gain formula

1. A formwork device for embedding the joints, including a formwork board with a pressure device,

characterized in that, in order to reduce the time of installation and dismantling and to ensure the safety of work, the formwork panel is made in the form of two decks, interconnected by a frame of two

horizontal and one vertical sliding pipes, while in the lower part of the vertical pipe there is a rigidly fixed plate with a pocket and with arcuate levers hinged on it,

opposite ends hinged to the decks, and the clamping device is made in the form of a sliding rack installed at an angle to the plane of the formwork panel and connected by an upper end using a pin with a pocket on the plate .2. The device according to claim 1, characterized in that for fixing open decks

. in the off position, it is provided with a locking device made in the form of a hinge from a steel plate, and the vertical pipe is made with a hole in which a locking device is placed, with a hinge arc discharged from the hole, and the ends of the hinge are pressed to both sides of the hole.
