Description

Fixed device of connect box for lamp

The present invention relates to a fixing device for a ceiling lamp junction box for fixing a junction box for fixing the ceiling lamp at the same time as connecting the wire to the ceiling lamp when the construction of the building, more specifically, the insertion hole in the lower outer periphery of the junction box A plurality of first and second coupling portions each formed to protrude integrally, the first and second coupling portions being tightly connected and fixed by a support that is inserted or separately provided in respective insertion holes formed in the first and second coupling portions; The first and second fasteners are respectively inserted into a plurality of fastening holes formed in the formwork used in the building construction by providing a plurality of second fasteners, so that the connection box can be firmly fixed, and thus the construction of the junction box is convenient. It can be performed quickly to improve the work efficiency and shorten the construction period due to the construction of the building. The present invention relates to stabilizer.

As is well known, the recently constructed middle and high-rise buildings are mostly formed of reinforced concrete structures. First, a plurality of formwork provided in a predetermined form is connected to designate the range and location of reinforcing steel and concrete. After installing the reinforcing bars of the building spaced apart from the upper part of the formwork by a certain type to form pillars, floors, and stairs, the concrete is placed in a certain thickness to the top so that the reinforcing bars are embedded. The new building will be built with multiple floors.

At this time, a plurality of junction boxes in which the wire piping and ceilings are fixed and installed to install the lights to illuminate the interior of the building are made at the same time as the rebar installation, and the junction box is made of synthetic resin as shown in FIG. 1. Alternatively, the open lower portion of the main body 10 formed of a metal material is positioned downward, and then fixed to the plurality of fixing pieces 20 formed at the lower outer periphery of the main body 10 by nails 30 to connect the connection box ( When the concrete is placed in the state in which 1) is firmly fastened to the upper part of the formwork 3, and after the predetermined time has elapsed, the formwork 3 is removed and the junction box 1 is connected to the concrete floor, that is, the ceiling. In a buried state, the ceiling lamp (not shown) can be installed.

However, the junction box 1 fixed by the nail 30 as described above has a problem in that the efficiency of work is deteriorated due to the hassle of removing the nail 30 protruding from the ceiling after removing the formwork 3. When the nail 30 is removed, the junction box 1 is frequently broken, and the repair or replacement cost is burdened with many problems.

In order to solve this problem, various types of fixing devices have been proposed to fix the junction box. For example, as shown in Patent Registration No. 10-0889349, it is buried in the ceiling of a building, and the luminaire is installed through a screw rod. In the luminaire mounting apparatus for mounting, the nut member receiving groove is formed in the upper end portion, the lower body having an insertion hole formed therein, the nut member installed in the nut member receiving groove, coupled with the upper end of the lower body, Luminaire mounting apparatus has been proposed, including an upper body is formed with a screw rod receiving portion for adjusting the installation height of the screw rod.

However, the above-mentioned mounting apparatus has a large number of components, and its structure is so complicated that it takes a long time to assemble and install, as well as to remove the formwork after removing the nuts fixing the plate during the dismantling of the formwork, so the work time is long. It takes a long time to reduce the efficiency, and if the formwork is removed without removing the nut, the expensive formwork is broken and the cost of maintenance has not been greatly improved.

Therefore, in order to solve the above problems, the present invention is formed to protrude integrally a plurality of first and second coupling portions each formed with insertion holes in the lower outer periphery of the plurality of connection boxes on the lower outer periphery of the junction box, In the plurality of fixing holes formed in the formwork used in the construction of the building provided with a plurality of first and second fasteners are closely connected and fixed by the support is inserted into each insertion hole formed in the first and second coupling portion or provided separately By inserting the first and second fixtures, respectively, so that the junction box can be firmly fixed, the construction of the junction box can be carried out conveniently and quickly, thereby improving the efficiency of the work and maintaining no damage to the demolished formwork. For ceiling lights that can reduce management costs and also significantly reduce the cost of construction by shortening the construction period for new building construction. The purpose is to provide a fixing device for the junction box.

In order to achieve the above object, the present invention is made of a polygon with an open lower portion, and the outer periphery is installed on the ceiling during the dismantling of the formwork by installing a main body formed with a plurality of pipe connectors protruding and fixed to the ceiling. Applied to the junction box for the ceiling lamp, it is formed to protrude integrally to the lower outer periphery of the main body, a plurality of first coupling portion formed with a predetermined depth of insertion grooves in the front center, and protrude integrally to the lower outer periphery of the main body Is formed, the insertion groove is formed in the lower center, one side is closely inserted in a horizontal state in the second coupling portion and the insertion groove formed in the first coupling portion through the binding grooves on both sides of the insertion groove, the other side The upper end is inserted into the upper support is formed in the fastening hole formed in the upper support, the fastening hole formed in the support, the lower end of the first height is tightly inserted into the fixing hole formed in the formwork Sphere, and is inserted and fixed tightly in the insertion groove formed in the second coupling portion, the lower end is fixed to the main body in close contact with the upper surface of the formwork by the second fixing sphere is tightly inserted into the fixing hole formed in the formwork In the fixing device of the junction box for the ceiling lamp, the first fixture is a plurality of stoppers on the outer periphery between the coupling pin formed by symmetrically divided upper and lower parts of the body of the elliptic form, and the coupling pin formed on the body and the upper part of the body. It characterized in that it is formed to protrude integrally so that the coupling pin formed in the upper portion of the body is inserted into the fastening hole formed on one side of the support to be firmly fastened.
