Description

Fixture for concrete ceiling box {Alumium form mounting block for concrete ceiling box}

The present invention relates to a fixture for a concrete sealing box detachably assembled to a concrete sealing box so that the concrete sealing box installed on the building ceiling during indoor piping construction can be poured using a separate aluminum flooring material. Concrete that allows the ceiling floor to be evenly cured during concrete pouring work by replacing the aluminum slab with excellent watertightness instead of the wood slab flooring material used for the concrete flooring of the building ceiling where the concrete sealing box is installed. It relates to a fixture for a sealing box.

In general, the outlet box for indoor piping, which is used for wiring work such as electric wires, telephone lines, or TV antenna lines of buildings such as apartments or buildings, is mounted between the ceiling of the building and the reinforcing walls of the building prior to the concrete placement work. It is configured to connect and disperse excellent flexible conduits. At this time, the concrete ceiling box of the ceiling of the building used as the outlet box for indoor piping or the wall outlet box of the inner wall of the building are conduits in which the wires are concentrated through a plurality of connection ports. They can be connected and branched to each other in the corresponding direction for concrete pouring.

On the other hand, the concrete sealing box used for indoor piping of the building ceiling, as shown in the use state of Figure 3, the wood slab flooring material (15) commonly used as a ceiling floor for forming the floor of the building ceiling during concrete pouring work The concrete sealing box 20 is fixed to the nail 16 or a screw, and then fixed, and then assembling and fixing the connector 10 with a plurality of connection holes 24 formed through the concrete sealing box 20 It could be configured as a switch box for indoor wiring to the ceiling of a building through concrete pouring work while connecting conduits (not shown).

By the way, the concrete sealing box 20 so far is concrete pouring work in the state of fixing the nail 16 or screw on the wood slab flooring material (15) used as the ceiling floor during the concrete installation work of the building ceiling As it is implemented, as a result, the concrete floor surface of the building ceiling from which the wood slab flooring material 15 has been removed is not only smooth and rough finish, but also the wood slab in which the moisture contained in the concrete is weak during concrete curing. Not only does the floor of the building become dirty as it falls under the flooring material (15), but also due to the material properties of the wood slab flooring material (15), its use frequency and service life are short, and it is very inconvenient to move to the construction site and prepare itself. there was.

Unexplained reference numeral 25 shows a fixing protrusion protruding from the bottom of the sealing box 20 so that the sealing box 20 on the wood slab flooring material 15 can be fixed by coupling the nail 16 or the screw. .

The present invention has been devised in view of the above situation, and concrete pouring work is replaced with aluminum watertight material having excellent water-tightness instead of wood slab flooring material used as the ceiling floor material in the concrete ceiling of the building ceiling in which the concrete sealing box is installed. The purpose of the present invention is to provide a fixture for a concrete sealing box that can be fixed to the concrete sealing box detachably fitted to the aluminum flooring material so as to uniformly pour the ceiling floor surface.
