Description

(54) DEVICE FOR LAYING A MORTGAGE ELEMENTS AND FORMING NESTS UNDER INSTALLATION ELECTRIC ARM

through and deaf, one or two at an angle to each other, depending on the design of this node in the finished panel. The second mortgage element 10 is freely mounted on the cylindrical part 11 of the housing and is pressed with the ends of its part against the fixed sheet 12.

The device works as follows.

Before forming the panel, with the cassette compartments opened, the devices are placed at the design points of the nests, a glass is screwed into the welded blind nut, with a loosened screw, a housing is inserted in which the number of Sockets, their design and arrangement correspond to the technolabic execution of this socket. By turning the casing, they are oriented in the direction of the formed channels in the panel, while this position is fixed by screws. After placing the required number of devices, the forming sheets are shifted. At the same time, the gap between the element and the sheet is eliminated due to the spring device, if the deviations of the forming space in width will be within 5 mm or less, or 10 mm or more from the nominal one. . Then the reinforcement is lowered into the molding space, and, if necessary, the heating registers insert the ducts into the slots and pour the concrete,

When the cassette is disassembled, a movable sheet with a welded nut and a glass is taken away, and the glass screws, resting against the wall of the groove, draw out the body. Embedded elements remain in the body of the panel.

In the event that another series of panels are manufactured in this cassette, the devices are retooled. To do this, the cup with the housing is unscrewed from the nut and I place the threaded cap flush with them, the trace left by them on the finished panel is not deep (about 12 mm) and is easily rubbed off with a solution .

Using the proposed device for embedding embedded elements and forming sockets for introducing electrical wiring to them, there is no need for any additional work on fine-tuning this node. The self-contained elements in the finished product have a clean inner surface and are ready for installation of installation devices, their ends are flush with the panel surface and have a good aesthetic appearance.

Replaceable housings, different in the design of the channeling jacks, allow the device to be used for single and two-wire electrical wiring at an angle to each other. By design, the device is no more difficult to manufacture and more reliable in operation, but it requires monitoring the state of the gasket, which is easily replaced. The device is quickly removed from the attachment point and can also be quickly installed in a new place.

The device may be applicable for embedding the embedded elements and receiving the nests in concrete and reinforced concrete products, manufactured not only in vertical cassette installations, but also in horizontal forms. To do this, attach it to the bottom sheet.
