Unification connect for connecter of manhole etc and pipe}

The present invention relates to a manhole for jointly connecting sewage pipes to a manhole or retaining wall sphere at a construction site, and a connecting member for integrally coupling the pipe body, and more particularly to a manhole that can cope with a small outer diameter of the sewer pipe. It relates to a connection member for integral coupling of the back and the tube.

When forming a movement route such as sewage, rainwater and communication cable in the basement, a plurality of sewer pipes (hereinafter referred to as "pipes") are formed from the retaining wall sphere, which is the beginning of the route, to form a movement route. At the point (hereinafter referred to as the "branch point"), the manhole is used to distribute or intersect the path.

The tubular body 107 is supported by the external connection member 111 by tightening the tightening band 113b in the band groove 113c in the state inserted into the pipe insertion part 113. At this time, the slit portion 113a formed in the tube insertion portion 113 is to correspond to the diameter and the connection angle of the tube body 107, and corresponds to the diameter of the tube body as the slit portion 113a is opened.

The internal connection member 121 has an airtight portion 123 protruding in a spherical shape in the center region and an attachment portion 125 extending outward in a plate shape in the circumferential region of the airtight portion 123. The airtight portion 123 is in contact with one end of the tube body 107 facing the inside of the manhole 101 in the state coupled to the external connection member 111 to hermetically seal the tube body 107.

An inner connecting member 20 coupled to the outer connecting member 10 and an inner formwork 5 forming an inner wall surface of the manhole 3 and the like and hermetically sealing one end of the tubular body 7, and a relatively small diameter tubular body. (7) includes a diameter adjusting ring 30 for adjusting the diameter so as to couple to the external connection member (10).

The external connection member 10 has a structure in which the tube inserting portion 11 into which the tubular body 7 is inserted and the external attaching portion 13 extending outwardly in a plate shape in a region around the rear end of the tube inserting portion 11 are integrally formed. Has

The tube insertion portion 11 has a funnel shape extending from the front to the rear, and at least one slit portion 15 is cut at equal intervals along the circumferential direction in the front end region. And, on the outer circumferential surface of the slit portion 15 is formed a band groove 17 for coupling the tightening band 17a for maintaining the insertion state of the tubular body (7).

The tubular body 7 is supported by the external connection member 10 by tightening the tightening band 17a in the band groove 17 in the state inserted into the pipe insertion part 11. At this time, the slit portion 15 formed in the tube inserting portion 11 is to correspond to the diameter and the connection angle of the tube body 7, the diameter of the tube body 7 is the slit portion 15 of the front end of the tube inserting portion (11) When the diameter is larger than the inner diameter, the slit portion 15 may be opened to correspond to the diameter of the tubular body 7.

Here, the external connection member 10 may be made of a single material, as shown in the drawing, it may be made of a bisected structure of more than two equals, depending on the construction conditions or needs. In addition, the external connection member 10 can be modified so that the external attachment portion 13 can also be used as an external formwork forming an outer wall such as a manhole.

The internal connection member 20 has an airtight portion 21 projecting in a circular arc shape in the central region, and an internal attachment portion 23 extending outwardly in a plate form from the circumferential region of the airtight portion 21. The airtight portion 21 is in contact with one end of the tube 7 facing the inside of the manhole 3 and the like to hermetically seal the tube 7.

At this time, the airtight portion 21 of the internal connection member 20 may be variously formed in the shape of a protruding partial arc, cone, hemisphere and the like. And the airtight part 21 is produced in one side eccentric shape when installing the pipe body 7 in the bottom area | regions, such as the manhole 3, and airtight one end of the pipe body 7.

Here, the internal connection member 20 may be made in a bisected structure of two or more parts and used in a mutually separate combination, so that the transport and management may be convenient, and may suitably cope with the construction conditions (work space narrow, etc.). . In addition, the internal connection member 10 is deformable so that the internal attachment portion 13 can also be used as an internal formwork forming an inner wall such as a manhole.

Here, the material of the external connection member 10 and the internal connection member 20 is a synthetic resin such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), FRP or acrylic resin Materials, metal plates such as tin and the like, or thick fabrics such as canvas, rubbers, and the like can be used.

On the other hand, the diameter adjusting ring 30 is produced in a ring shape is interposed between the slit portion 15 and the tube (7) of the tube insertion portion (11). The diameter adjusting ring 30 is not formed between the tube 7 and the tube insert 11 when the diameter of the tube 7 inserted into the tube insert 11 is smaller than the inner diameter of the slit 15. This is to avoid.

Here, the diameter adjusting ring 30, as described above, is preferably installed to be airtight between the inner diameter surface of the slit portion 15 and the outer peripheral surface of the tubular body 7 in the front end region of the tube insertion portion 11, According to this, it can be interposed between the inner surface of the inner region of the tube insertion portion 11 and the tube (7). In this case, the outer circumferential surface of the diameter adjusting ring 30 is manufactured to be in contact with the inner circumferential surface of the tube insertion portion 11.

With this arrangement, when the relatively small tubular body 7 is integrally coupled to the manhole 3 or the like as shown in FIG. 4 by using the connecting member 1 according to the present embodiment, first, the internal form 5 is internally formed. A coupling opening corresponding to the periphery of the airtight portion 21 of the connection member 20 is formed, and the internal connection member 20 is coupled to the inner surface of the connection opening 20 by engaging the internal attachment portion 23 of the internal connection member 20. To the inner formwork (5). At this time, the coupling openings formed in the outer mold 4 and the coupling openings formed in the inner mold 5 are formed on the same axis. Here, the inner connecting member 20 may be directly coupled to the outer circumferential surface of the inner formwork 5 without forming a coupling opening in the inner formwork 5.

Then, the diameter adjusting ring 30 is coupled to the outer circumferential surface of the rear end region of the tubular body 7, and the rear end portion of the tubular body 7 is inserted into the tube inserting portion 11 of the outer connecting member 10 so as to adjust the diameter adjusting ring ( 30) is placed in contact with the inner diameter surface of the slit portion 15 of the tube insert (11). At this time, the rear end of the tubular body 7 extends rearward by a position blocked by the airtight portion 21 of the internal connection member 20. In addition, the exponential ring (9) is coupled to the section between the diameter adjustment ring 30 and the rear end of the tube (7).

Then, a coupling opening corresponding to the rear end of the tube insertion portion 11 of the external connection member 10 is formed in one region of the external formwork 4 corresponding to the position at which the tubular body 7 is to be coupled, and the circumference of the coupling opening. Coupling the outer connection member 13 of the outer connection member 10 coupled to the tube body 7 is coupled to the outer connection member 10 to the outer die (4). At this time, the tubular body 7 is horizontal.

Can be adjusted.

In this state, when concrete is poured into the outer mold 4 and the inner mold 5 to form the manhole 3 and the like, the tubular body 7 is integrally coupled to the manhole 3 and the like. At this time, the coupling portion between the manhole 3 and the tubular body 7 is reinforced by the concrete filled in the inner space of the pipe insertion portion 11 region of the outer connecting member 10. Then, when the tubular body 7 having a relatively small diameter is joined by the tubular diameter adjusting ring 30 provided between the tubular body 7 and the tube inserting portion 11, concrete does not leak out and the tubular body 7 is formed in the manhole 3 and the like. Are integrally combined.

On the other hand, Figure 5 is a perspective view of the coupling member for integral coupling of the manhole and the tubular body according to the second embodiment of the present invention, Figure 6 is a cross-sectional view showing a state of using the connecting member of FIG. As shown in these drawings, the connection member 1 'according to the present embodiment has the same configuration as the above-described first embodiment except for the diameter adjusting ring 30.

It has a position fixing part 33 which is expanded to the rear of the shape and fits in contact with the inner peripheral surface of the pipe insertion part 11. The diameter adjusting ring 30 compensates for the diameter of the tubular body 7 having a relatively small diameter, and the position fixing part 33 is placed in the concrete pouring or other state in the state in which the tubular body 7 is coupled to the external connecting member 10. When the construction work, the pipe 7 is pushed outwards to fix the coupling position of the pipe 7 so that the position does not change.

Here, the position fixing part 33 is formed in a shape corresponding to the inner circumferential surface of the expansion section 11 of the pipe insertion part 11, and the tubular body is formed at the lower end of the manhole 3 or the like so that sewage does not accumulate in the inner bottom of the manhole 3 or the like. In the case of connecting 7), the pipe insertion portion 11 is formed in a lower eccentric structure, and in this case, the position fixing portion 33 is also formed in a lower eccentric structure. The position fixing portion 33 may have various structures corresponding to the shape of the expansion section of the pipe insertion portion 11.

The connecting member 1 ′ according to the present embodiment compensates the diameter of the tube 7 having a relatively small diameter by the diameter adjusting ring 30 and at the same time accurately fixes the coupling position of the tube 7. We can plan construction.

As such, by providing a connection member of the tube and the like with a manhole having a diameter adjusting ring interposed between the inner surface of the inner portion of the tube insertion portion of the outer connecting member and the tube,

It can correspond to the diameter size of.

In addition, even if the diameter of the tubular body of the tubular body is smaller than the inner diameter of the tube inserting portion of the outer connecting member does not generate a gap between the tubular body and the tube inserting portion can be installed without fear of concrete leaking during concrete pouring.

In addition, since it can correspond to the diameter of the various tube body, it is economical not to manufacture an external connection member having a tube insert of a separate standard.

As described above, according to the present invention, there is provided an economical manhole and a connection member for integrally joining the tubular body, which can be easily integrated into the manhole or the like even with a small diameter tubular body.
