Conduit line adapter of manhole for electric and electronic communications

The present invention relates to a pipeline adapter applied to the manhole for the transmission and distribution of electrical and electronic communications, more specifically, the concrete between the adapter body and the inner cover or outer cover in the molding process of the manhole formed by concrete pouring In order to prevent the penetration of the inner cover and the outer cover by forming a water-tight ring in the form of a "┣" in the cross-section, thereby preventing the concrete from penetrating into the coupling gap between the adapter body and the cover by the water-tight ring Accordingly, the conventional pre-silicone application or post-silicon removal is unnecessary and very effective, and it is a manhole channel adapter that can take an excellent economic benefit by improving the working speed for the pipe construction.

In general, in order to transmit or distribute by using a cable for electrical or electronic communication, a transmission and distribution line using a telegraph pole or underground manhole is constructed. In recent years, as a kind of commercialization to improve urban aesthetics, it is becoming more common to build underground transmission and distribution lines instead of ground and distribution lines.

In order to construct the underground transmission and distribution lines as described above, manholes for branching and connection of cables are indispensable. The manholes have a large internal space. Various types and types of cables can be easily branched or connected.

The above-mentioned manhole for underground transmission and distribution lines is usually molded and completed through on-site casting method (RC) or prefabricated method (PC) by factory manufacturing. In general, the construction period is shorter and higher quality than RC method. And PC (PC) method having excellent water tightness and durability is more widely applied.

Briefly describing the production process of the manhole completed by the PC method, first, using the cut reinforcing bar to produce a reinforcing bar role of the reinforcement of the manhole. Subsequently, in the state where the reinforcing steel bar is inserted into the mold for forming a manhole, assembly materials such as an duct adapter are poured and concrete is poured, followed by curing through steam. Thereafter, after demolding the manhole molding from the mold, the manhole may be transported and assembled to a site as needed in a state where it is placed in a yard.

At this time, in the production process of the manhole as described above, as shown in Figure 1 on the sidewall of the manhole 100, a plurality of pipeline adapters 110 are formed together in a fixed state, the pipeline adapter 110 is a cable, etc. In order to directly connect the pipe body for connecting the wire, the pipe body is used as a guide and a seal for arranging wires and communication cables installed for electrical and electronic communication from the outside of the manhole into the manhole. By connecting the pipeline body with the pipeline adapter 110 in the construction of the manhole, and through the wires and communication cable to wire the inside of the manhole and to seal the gap between the wire or communication cable and the pipeline body underground transport, The construction of the distribution line is completed.

As shown in FIG. 2, the pipe fitting adapter 110 protrudes from the flange portions 111 and 111 ′ on both sides thereof, so that the concrete of the manhole is molded over the entire length of the flange portions 111 and 111 ′. The manhole 100 is firmly coupled and cured, and the inner cover 113 and the outer cover, respectively, on both sides of the passage adapter 110 through the screw connection portion 112 formed in the interior of the pipeline adapter 110 114 is screwed.

Accordingly, when the inner cover 113 and the outer cover 114 are screwed into the both ends of the conduit adapter 110 as described above, when the conduit adapter 110 is embedded in the forming process of the manhole 100. By removing the inner cover 113 or the outer cover 114 it is possible to obtain a through hole for the portion in which the conduit is located.

At this time, when the concrete is poured in a state in which the pipeline adapter to be embedded in the manhole is temporarily fixed to the rebar network, the concrete is leaked to the coupling portion of the pipeline adapter 110 and the inner cover 113 or the outer cover 114. In order to penetrate, it is necessary to form a separate silicone coating layer 115. As the concrete penetrates into the coupling part of the conduit adapter and the inner cover and the outer cover as described above, when the spilled concrete is cured as it is, the inner part of the conduit adapter Since the cover or the outer cover cannot be removed and removed, the silicone coating must be performed as a kind of preliminary work.

Therefore, when the concrete is poured by curing in the state in which the silicone coating operation to the coupling portion of the inner cover and the outer cover in advance as described above, even if the concrete is leaked and cured in the coupling portion to remove the silicone coating layer Since the cured concrete can be easily removed according to the conventional manhole forming process, the pre-work by the silicone coating as described above and the post-work to remove the silicone coating layer after curing are common.

However, such pre-working and post-working for the removal of silicon are extremely uneconomical because they require a large number of workers and working time, and at least dozens of channel adapters are formed for a single manhole. The above pre and post work, which relies on manual work in proportion to the number of duct adapters, results in economic losses due to poor working efficiency and additional burden of labor costs due to relatively long working time.

In particular, when the pre-working of the silicone coating is poor, the outflowing concrete penetrates into the coupling gap of the inner cover or the outer cover and hinders their rotational force, thus requiring a very skilled work and an operator. The silicon is not neatly removed even when working, which is not good.

In addition, even when the wiring is changed in the wiring process by the duct, the sealing operation for the corresponding duct adapter is to be performed, and in this case, the silicon coating operation must be repeated as above, and thus has the same problem and discontinuity.

Accordingly, the airtight method by the silicon is not very economical and water tightness is not guaranteed, and the appearance is not neat and beautiful, so desperately requiring a pipeline adapter having an improved watertight structure accordingly It is true.

The present invention has been made to solve the problems as described above, inserting the water-milling in the form of "┣" in the cross-section on the outer surface of the flange of the inner cover and the outer cover coupled to the body of the duct adapter, the outer surface of the water sealing ring is It consists of an inclined surface that is gradually extended toward the outside, and on the side of the settled groove portion of the adapter body in which the flange portion of the inner cover and the outer cover is formed, the inclined contact surface corresponding to the inclined surface, the inner cover and the outer cover to the adapter body At the same time, the inclined surface of the water milling ring and the inclined contact surface of the settling groove are in close contact with each other so as to completely remove the gap.

SUMMARY OF THE INVENTION An object of the present invention is to provide a manipulator adapter for manholes for electrical and electronic communications, which does not need to perform a silicone pre-application or a post-silicone removal procedure, thereby reasonably overcoming all the problems of the conventional duct adapter. It is.

The present invention for achieving the object as described above, the screw hole is formed therein and the adapter body having a flange portion protruding at both ends, both sides of the adapter body larger than the inner diameter of the screw hole and smaller than the outer diameter of the flange portion In the manhole duct adapter of the inner hole consisting of a settled groove of the inner diameter, the inner cover and the outer cover formed with a threaded portion on both sides of the adapter body through the screw hole, respectively,

The inner cover and the outer cover is formed on one side of the expansion flange located in the settling groove, the side of these expansion flanges to form an insertion groove formed along the insertion groove of one side of the water-tight ring in the form of "┣" in cross section It is made by inserting into the insertion groove.

The present invention, by simply assembling the inner cover and the outer cover to the body of the duct adapter is in close contact with the coupling portion between the body of the duct adapter and the inner cover and the outer cover can completely remove the gap in the forming process of the manhole Even if the concrete leaks, the inner cover and the outer cover can be easily separated and removed by simple removal of the spilled concrete, and the conventional pre-silicone application and post-silicon removal work are omitted. It is very economical because it can shorten the construction period required for construction as well as the labor cost due to the reduction of workers, and the appearance is beautiful because there is no residue of silicone etc. on the exposed body of the adapter and the inner cover and outer cover. It is possible to construct higher quality distribution lines.

As shown in the illustration, the conduit adapter according to the present invention has an adapter body 10 having a through-hole screw hole 11 formed therein, and an inner cover 20 coupled to the screw hole 11 from both sides of the adapter body 10. And made of the outer cover 30, as the adapter body 10 is embedded in the manhole to be molded concrete will be able to use a combination of various pipes and guide pipes according to the pipe.

That is, the adapter body (10) is a circular tube formed inside the threaded hole (11) penetrating there is a flange portion (12, 12 ') having an outer diameter of expansion is formed at both ends, the adapter body Both sides of the (10) is formed with a settling groove (13, 13 ') having an inner diameter larger than the screw hole 11 and an inner diameter smaller than the flange portion 12 (12').

In addition, the inner cover 20 and the outer cover 30 is a screw portion 21, 31 is formed on the outer surface can be fastened to the screw hole 11 of the adapter body 10, the inner cover At one end of the 20 and the outer cover 30, expansion flanges 22 and 32 inserted into the settling grooves 13 and 13 'are formed to protrude.

Here, the ring 24 protruding to the inner surface of the inner cover 20 is formed for the purpose of hooking the traction wire provided on the inner side of the duct body (60).

In particular, the outer cover of the inner cover 20 and the outer cover 30 of the expansion flange 22, 32 to form an insertion groove 23, 33 to form a separate water-tight ring (40), The water sealing ring 40 is formed in the shape of a "┣" in the cross-section having a protrusion 41 on one side, and when the protrusion 41 is inserted into the insertion grooves 23, 33, the inner cover 20 ) And the outer surface of the expansion flanges 22 and 32 of the outer cover 30 will be in the form of a circular water-tight ring 40 wrapped around it, and the water-tight ring 40 to the outer surface of the expansion flanges 22 and 32. Only the outer surface of is exposed.

At this time, the inner surface of the settle groove (13, 13 ') of the adapter body 10 is formed inclined contact surface 14, 14' of gradually extending outward as shown in Figure 6, the water-tight ring ( The outer surface of 40 is formed with an inclined surface 42 having an inclined angle corresponding to the inclined contact surfaces 14 and 14 '.

Therefore, when the inner cover 20 or the outer cover 30 separated from the adapter body 10 as shown in the enlarged cross-sectional view of Figure 7 screwed to the adapter body 10, the inclined surface 42 of the water-tight ring 40 While contacting the inclined contact surfaces 14 and 14 'of the settle grooves 13 and 13', the wedge-shaped coupling structure between these inclined surfaces 42 and the inclined contact surfaces 14 and 14 ' The closer assembly is made, and the stronger the assembling of the inner cover 20 and the outer cover 30 with respect to the adapter body 10, the inclined contact surfaces 14, 14 'of the settle grooves 13, 13' and Since the inclined surface 42 of the water milling ring 40 is more closely contacted, the gap does not occur at all.

Therefore, the interior of the adapter body 10 as described above will be completely waterproof, the gap between the adapter body 10 and the inner cover 20 and the outer cover 30 does not occur at all. . Here, the water-tight ring 40 is ideal to use a urethane material and may be made of a material such as rubber or silicon as needed, and if it has a predetermined elasticity and resilience, it will not be affected by the material.

In particular, the water-milling ring 40 can be reused repeatedly, so that it has a very economical feature than the silicone caulking method that is damaged and removed after application as in the prior art. In the conventional case, the inner cover 20 or the outer cover ( 30) The silicone caulking was repeatedly performed in the process of separating or recombining, but the water-milling 40 in the present invention can be repeatedly reused, thereby greatly improving the work efficiency.

Thus, when pouring the manhole using the adapter of the adapter body 10 and the inner cover 20 and the outer cover 30 in a watertight coupling state as described above, the concrete and the adapter body 10 Even if leaked into the gap between the inner cover 20 and the outer cover 30 is to prevent the concrete from penetrating into these gaps to harden.

In addition, even if the spilled concrete is hardened on the surface of the inner cover 20 and the outer cover 30, simply remove the concrete formed on the surface from the adapter body 10 from the inner cover 20 or outer cover 30 To easily remove the removal or to open the inside of the adapter body (10).

Such a duct adapter of the present invention can prevent rainwater from penetrating into the interior from the outside of the manhole during the rainy season or rainy weather, and groundwater also penetrates from the outside of the manhole toward the inside through a water-tight ring 40 having excellent waterproofing effect. This can be prevented.

In addition, if you want to connect the installation of the pipeline body 60 as shown in Figure 8 also screw the end of the pipeline body 60 to the inner threaded hole 11 of the adapter body 10 for various cables Connection and fixation is easy.

Here, the passageway body 60 is also inserted into the watertight ring 40 which is also inserted into the outer surface of the flange portion 61 on one side to fix the outer cover 30 in the state of the present invention in the pipeway adapter of the present invention. When the body 60 is combined, the watertight ring 40 and the closet groove 13 and 13 ′ of the pipeline body 60 are completed, so that a perfect waterproof action from the outside may be expected.

In particular, the inner cover 20 which is screwed to the adapter body 10 by forming a rubber packing 50 made of a soft elastic material in the bottom surface of the settled grooves 13 and 13 ′ of the adapter body 10. As the rubber packing 50 is pressed and adhered by the expansion flanges 22 and 32 of the outer cover 30, the waterproofing effect on the inside of the adapter body 10 or the inside and the outside in the manhole is increased. Even better. At this time, the rubber packing 50 may be molded integrally with the water-tight ring 40, the inner cover 20 in the state of integrally molding the water-tight ring 40 and the rubber packing (50). Or in the case of forming a close contact with the flange portion 61 of the outer cover 30 or the pipeline body 60 when coupling the inner cover 20 or outer cover 30 or the pipeline body 60 to the pipe adapter Through the integral water milling ring 40 and the rubber packing 50 as described above it is possible to significantly increase the work efficiency as well as more excellent watertight action.
