Description

Slave Laying Type Connecting Device of Electric Wire Pipe

The present invention relates to a slab embedded conduit connection member. More specifically, the present invention relates to a slab-embedded conduit connection member that can selectively use any one of the smooth and corrugated pipes connected to the inlet and the outlet to reduce costs, reduce work time, and improve rigidity. .

In general, during the construction of the building, the conduit is buried and the concrete slab is constructed. After that, the electric wire and the communication wire are introduced through the conduit to perform the wiring work. As the conduit, a smooth tube of a straight state and a corrugated tube bent freely are used. The smooth tube is called a HI tube (High Impact tube), and the corrugated tube is called a flexible tube or a CD tube (Combind Duct tube).

When constructing a building, the toilet wall or bathroom wall is not constructed with concrete, but after the concrete slabs are constructed, they are stacked with bricks to form walls. In this case, wires are also drawn into the wall to perform wiring work. Accordingly, before the slab is constructed, a conduit connection member is installed at the position where the wall is to be embedded and embedded in the slab.

That is, Figure 1 is a view showing the installation state of the conventional conduit connection member, Figures 2a and 2b is a plan view and a front sectional view of the conventional conduit connection member. A conduit connection member 1 embedded in the concrete slab 4 in a state in which the smooth pipe 2 is coupled to the upper portion as shown in FIG. 1; A wall (5) formed by stacking bricks at a lower portion of the conduit connection member (1); A corrugated pipe (3) passing through the center of the wall (5) and having an upper end coupled to a lower portion of the conduit connection member (1); It consists of a switch box (6) which is installed at the lower end of the corrugated pipe (3).

The conduit connecting member (1) is formed in the upper portion is inclined at an angle, the body 10 through which the inlet (11) is formed in the upper portion; A coupling pipe 12 formed downward in the body 10 and having an outlet 13; When the concrete slab (4) is installed in the lower portion of the body 10 is composed of a fixing portion (14) through which a fixing member (not shown) for firmly fixing the conduit connection member (1) to the formwork.

3 is a view in which a corrugated pipe is coupled to a conventional conduit connection member, FIG. 4A is a plan view of a corrugated pipe, and FIG. 4B is a plan view of a smooth pipe. In addition, Figure 5 is a view coupled to the smooth pipe to the outlet of the conventional conduit connection member.

A smooth pipe 2 or a corrugated pipe 3 can be selectively coupled to the inlet 11 side of the conduit connection member 1 currently used, but only the corrugated pipe 3 is used on the outlet 13 side. That is, the fixing nut 15 is coupled to the inlet 11 side, so that the smoothing tube 2 or the corrugated tube 3 can be selected and coupled, but the fixing nut cannot be coupled to the outlet 13 side so that the corrugated tube 3 cannot be combined. The inner diameter of the outlet opening 13 is formed in the same manner as the outer diameter of A, and an adhesive is applied to the outer surface of the corrugated pipe 3 to be inserted into the outlet opening 13.

At this time, the outer diameter (D1) of the corrugated pipe (3) and the outer diameter (D2) of the smooth pipe (2) shown in Figures 4a and 4b are different from each other, even if the same designation, which is determined by KS. This will be easily understood by the following [Table 1].

TABLE 1

[Table 1] is a comparison table comparing the outer diameter size for the name of the smooth pipe (2) and corrugated pipe (3).

As shown above, even if the same designation, it can be seen that the outer diameter of the smooth tube 2 is larger than that of the corrugated tube 3.

Therefore, in order to use the smoothing pipe 2 on the outlet 13 side, as shown in FIG. 5, after fixing the auxiliary connection corrugated pipe 21 used for the coupling on the outlet 13 side with an adhesive, The heterogeneous coupler 20 is coupled to the lower end to connect the smooth tube 2. At this time, the heterogeneous coupler 20 is made to connect the different types of smooth pipe (2) and corrugated pipe (3).

As described above, when the smooth pipe 2 is to be coupled to the outlet 13 side of the conduit connection member 1, the auxiliary connection corrugated pipe 21 and the heterogeneous coupling port 20 are required, so that a lot of parts are required. Due to the construction cost is increased, there was a problem that takes a lot of construction time.

That is, since the conduit connection member 1 to the switch box 6 is close to the vertical, it is preferable to fix it firmly with the smooth pipe 2 rather than the corrugated pipe 3 freely bent, but coupled with the smooth pipe 2. To be the same problem occurs.

Accordingly, in order to reduce the parts and shorten the construction time, the corrugated pipe 3 is simply connected to the switch box 6 without using the corrugated pipe 2 to the outlet 13 of the conduit connecting member 1. Therefore, the problem that the rigidity is poor.

The present invention has been made to solve the problems of the prior art, an object of the present invention is to provide a slab-embedded conduit connection member that can be coupled to the inlet and outlet of the conduit connection member by selecting a smooth or corrugated pipe. .

The structure of the body 101 of the conduit connection member 100 of the present invention is the same as that of the related art, except that the inner diameter of the outlet 104 matches the outer diameter of the smooth tube 2 so that the adhesive is applied to the outer surface of the smooth tube 2. It is applied so that it can be fixed to the outlet 104.

In addition, to form a corrugated pipe coupler 110 is provided with a coupling hole 111 having the same inner diameter as the outer diameter of the coupling pipe 103, the lower portion of the corrugated pipe coupler 110 to fix the corrugated pipe (3) A plurality of locking holes 112 can be formed.

At this time, as shown in Figure 6 by forming a longer length (H2) from the upper end of the corrugated pipe coupling port 110 to the upper end of the locking hole 112 than the overall length (H1) of the coupling pipe 103 It is preferable that the locking hole 112 for fixing the corrugated pipe 3 is formed so as not to contact the lower end of the coupling pipe 103.

In addition, a plurality of compression protrusions 105 may be formed on the outer surface of the coupling pipe 103 and the inner surface of the body 101 to firmly fix the corrugated pipe coupling hole 110, and the corrugated pipe coupling hole ( Grooves corresponding to the crimp protrusion 105 may be formed on the inner and outer surfaces of the 110.

The inventive conduit connection member 100 made as described above may selectively couple the smooth tube 2 or the corrugated tube 3 to the outlet 104 as shown in FIGS. 7A and 7B.

That is, when the corrugated pipe 3 is inserted into the outlet 104, the locking hole 112 of the corrugated pipe coupling port 110 is inserted into the groove of the corrugated pipe 3, and the corrugated pipe 3 is prevented from falling down. Inserting the smooth tube 2 coated with the adhesive outside the insertion portion into the outlet 104, the smooth tube 2 is attached to the outlet 104 by the adhesive to prevent the smooth tube 2 from falling down do.

At this time, when the smoothing tube 2 is inserted, the latching opening 112 of the corrugated pipe coupler 110 is folded at a right angle as shown in FIG. 7B, which also supports the smoothing tube 2. (2) is prevented from falling down.

Accordingly, the smoothing pipe 2 and the corrugated pipe 3 may be selected and coupled to the inlet 102 of the conduit connection member 100 by the fixing nut 106, and the corrugated pipe coupling unit 110 may be connected to the outlet opening 104. By selecting the smooth tube (2) and the corrugated tube (3) can be combined.

TABLE 2

As shown in Table 2, in the conventional inlet 11, the smooth pipe 2 and the corrugated pipe 3 were selected and combined in various ways, but only the corrugated pipe 3 was used on the outlet 13 side. That is, although the vertically down portion is firmly fixed when the smooth pipe 2 is installed, the reason for installing the corrugated pipe 3 is that the coupling of the smooth pipe 2 to the conduit connecting member 1 is the same as described above. As such, the parts are required and the operation time is considerably high, so that the coupling of the smooth pipe 2 to the outlet 13 is mostly referred to as "NO GOOD".

However, in the present invention, since the smoothing pipe 2 or the corrugated pipe 3 can be variously selected and combined on the outlet 104 side, the inlet 102 and the outlet 104 are both the smooth pipe 2 or the corrugated pipe 3. It is possible to combine a variety of choices.

Thus, with respect to the conduit connection member of the present invention, all of the design changes of each component within the scope of the present invention is considered to be included in the scope of technical thought.

According to the present invention, there is an effect that the conduit coupled to the inlet and the outlet can be selectively used in a variety of smooth and corrugated pipe.

In addition, since the smooth pipe and the corrugated pipe can be combined without additional parts, the construction cost is reduced and the working time is shortened.
