Description

Technology Field

[0001] The present invention relates to a conduit connection box for a slab, and more specifically, to a conduit connection box for a slab that can minimize the perforation area of ​​the ceiling insulation, and can also make manufacturing convenient and reduce manufacturing costs. Background Technology

[0003] Generally, wiring boxes are embedded in the walls or ceilings of buildings. This applies even when the walls or ceilings are made of concrete; in such cases, conduits and wiring boxes are installed inside the formwork prior to concrete pouring. Consequently, even after the formwork is removed following concrete curing, the wiring boxes remain in their installed locations.

[0004] Since insulation is installed on the ceiling, the wiring box embedded in the slab is perforated at the location of the wiring box in the insulation, and a connection box is connected to the wiring box through the perforated area to open it toward the ceiling, and wiring is made through the open space.

[0005] FIG. 1 illustrates a wiring box for general slab installation and a connection box connected thereto. The wiring box (10) is typically configured as an octagonal housing, and the connection box (20) connected thereto is also configured as an octagonal tube shape. The connection is made by fixing the fixing hole (11) formed in the wiring box (10) and the connection piece (21) inserted in the connection box (20) with a screw.

[0006] At this time, since the shape of the connection box (20) is configured as an octagon to match the shape of the wiring box (10), when perforating the insulation material to accommodate the connection box (20), the perforation must be made with an outer size sufficient to accommodate the connection box (20), so a large amount of insulation material is inevitably lost, and in the subsequent process, a large amount of material cost is inevitably required to fill the space between the perforated part of the insulation material and the connection box (10).

[0007] In addition, since the metal connecting piece (21) is inserted into the synthetic resin connecting box (20), the injection molding process becomes complicated and there is a disadvantage that additional connecting pieces (21) are consumed. Prior art literature

[0009] Republic of Korea Published Patent No. 10-2023-0086177 (Published June 15, 2023) The problem to be solved

[0010] The present invention is proposed to improve upon the problems of the aforementioned prior art and aims to provide a conduit connection box for slabs that can minimize the perforation area of ​​the ceiling insulation, facilitate manufacturing, and reduce manufacturing costs. means of solving the problem

[0012] A conduit connection box for a slab according to the present invention for achieving the above purpose is connected by screw coupling to a wiring box installed embedded in a slab, and comprises: a body having an overall cylindrical shape; a donut-shaped flange formed at a contact position of the wiring box on the body; and screw fixing holes formed on both sides of the boundary position between the flange and the body so as to be screw-coupled with the wiring box.

[0013] In addition, the screw fixing hole position of the above body may be formed at the lower part as the rib is recessed inward.

[0014] In addition, a reinforcing wall may be formed around the screw fixing hole at the flange location.

[0015] In addition, the above screw fixing holes may be formed in multiple numbers at equal intervals.

[0016] In addition, an extension box is further provided having the same cylindrical shape as the body, with an elastic coupling hook protruding from one side and a coupling groove having a shape corresponding to the coupling hook formed on the inner wall of the other side, and a coupling groove is formed at the position corresponding to the coupling hook of the body so that the extension box is fixed to the body by the coupling of the coupling hook and the coupling groove, and another extension box can be continuously fixed to the extension box by the coupling of the coupling hook and the coupling groove. Effects of the invention

[0018] Since the conduit connection box for a slab according to the present invention is formed entirely in a cylindrical shape, when perforating the insulation material laid on the slab to form a space for connecting the connection box to the wiring box, the perforation can be done with a minimum area compared to the existing octagonal shape, thereby reducing insulation material loss costs. Furthermore, in subsequent processes, the work of filling the space between the connection box and the insulation material can be carried out very conveniently in the shortest amount of time, and there is an advantage of minimizing material costs.

[0019] In addition, since it can be fixed to a wiring box by screwing through screw holes without the need for separate metal connecting pieces, there is an advantage of reducing material costs as the connecting piece insertion process is not required. Furthermore, since multiple screw holes are formed in a row, there is also an advantage of being universally applicable regardless of the size of the wiring box within a certain range.

[0020] In addition, ribs are formed in a shape that naturally recedes inward from the top to the bottom of the body, so there is an advantage in that rigidity can be reinforced through these ribs even without an angular shape.

[0021] In addition, an extension box is further provided that has the same cylindrical shape as the body, has an elastic coupling hook protruding from one side, and has a coupling groove formed on the inner wall of the other side that corresponds to the shape of the coupling hook. Since the coupling groove is formed at the position corresponding to the coupling hook on the body, the extension box can be fixed to the body of the connecting box in a one-touch manner by the coupling of the coupling hook and the coupling groove, making the connection work very convenient, and the extension box can also be easily connected in a one-touch manner, which is an advantage.

[0024] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.

[0025] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0026] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0027] First, the conduit connection box for a slab according to the present invention will be described with reference to the illustrated drawings as follows.

[0028] FIG. 2 is a perspective view of a conduit connection box for a slab according to the present invention, FIG. 3 is a cross-sectional view of a conduit connection box for a slab according to the present invention, FIG. 4 is an exploded perspective view of a conduit connection box for a slab and a wiring box according to the present invention, and FIG. 5 is a cross-sectional view of the combined state of a conduit connection box for a slab and a wiring box according to the present invention.

[0029] A conduit connection box (100, hereinafter abbreviated as connection box) for a slab according to the present invention is connected by screw coupling to a wiring box (10) installed embedded in a slab, and comprises a body (110) having an overall cylindrical shape, a donut-shaped flange (120) formed at the wiring box contact position of the body (110), and screw fixing holes (130) formed on both sides of the boundary position between the flange (120) and the body (110) so as to be fixed to the wiring box (10) by screw.

[0030] At this time, the screw fixing hole position of the body (110) is formed with the rib (111) recessed inward and the screw fixing hole (130) formed in the lower part thereof, so that the connection work between the wiring box (10) and the connection box (100) is not hindered, and the rib (111) formed inside the body (110) naturally acts as a reinforcement, so that even if the body (110) is formed in a cylindrical shape overall, it can have a rigidity equal to or greater than that of the existing angled connection box.

[0031] In addition, a reinforcing wall (131) is formed around the screw fixing hole at the flange (120) position, so this configuration has the advantage of preventing the screw fixing hole (130) from becoming worn out even after long use, and also serves as a guide for the screwdriver.

[0032] At this time, the screw fixing holes (130) are formed in a number of equal intervals, so there is an advantage that they can be universally applied regardless of the size of the wiring box (10) within a certain range.

[0033] The slab conduit connection box (100) according to the present invention, configured as described above, perforates the insulation material laid on the slab to connect with the wiring box (10) installed embedded in the slab. Since the body (110) is generally cylindrical, the insulation material can be perforated in a circular shape slightly larger than the body (110), so the perforation can be done over a significantly narrower area compared to perforating the insulation material around the outer edge of the existing octagonal connection box. Accordingly, the cost of insulation material loss can be significantly reduced compared to the existing method.

[0034] In addition, when filling the space between the insulation material and the connecting box (100) in the subsequent process, convenient work can be performed in the shortest possible time, and there is an advantage that the amount of material required for filling can also be minimized.

[0035] Meanwhile, an extension box (140) can be continuously fixed to the connection box (100), and for this purpose, an extension box (140) having a shape similar to the connection box (100) according to the present invention is further provided.

[0036] FIG. 6 is a perspective view of an extension box according to the present invention, and FIG. 7 is a cross-sectional view of the combined state of a connection box and an extension box according to the present invention.

[0037] The extension box (140) according to the present invention is formed in a cylindrical shape identical to the body (110) overall, and has an elastic coupling hook (141) formed protrudingly on one side, and a coupling groove (142) having a shape corresponding to the coupling hook (141) is formed on the inner wall (142) on the other side.

[0038] In addition, a coupling groove (112) is formed at the coupling hook corresponding position of the body (110) of the connection box (100), so that the extension box (140) can easily secure the connection box (100) and the extension box (140) by one-touch coupling the coupling hook (141) to the coupling groove (112) of the connection box (100).

[0039] In addition, when fixing an extension box (140) and another extension box (140), the connecting hook (141) of the extension box (140) can be easily fixed by one-touch connecting it to the connecting groove (142) of the other extension box (140).

[0040] And, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the conduit connection box structure for slabs of the present invention can be implemented with various modifications by those skilled in the art.

[0041] Therefore, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
