Description

Interfloor piping connection apparatus and connection method {floor piping connection apparatus and connection method}

The present invention relates to an interfloor piping connection device and connection method that connects a penetrating sleeve unit embedded in a low-rise interfloor with a penetrating sleeve unit embedded in a high-rise interfloor using a pipe.

Generally, the internal space of a building is divided into a plurality of spaces by floors and walls between floors, and mounting holes through which various pipes can pass are formed in the frame of the building, such as floors and walls between floors. The mounting hole in the building frame is formed to be larger than the width of the pipe, allowing the pipe to pass through the mounting hole even if there is a design error when installing the pipe.

A first penetrating sleeve unit installed to be embedded in the interfloor of a lower floor and a second penetrating sleeve unit installed to be embedded in an interfloor of a floor immediately above the lower floor are connected through a pipe. Here, the pipe is applied as a sewage pipe.

Meanwhile, the pipe installation work connecting the first through sleeve unit and the second through sleeve unit involves inserting one first pipe into the upper side of the first through sleeve unit from the upper side to the lower side, and inserting the first pipe into the upper side of the first through sleeve unit from the upper side to the lower side. After inserting another second pipe from the bottom to the top, these pipes are connected to each other to ensure overall pipe connection.

Here, in the operation of inserting the first pipe in the downward direction on the upper side of the first through sleeve unit, the operator can visually check the insertion depth to some extent, but unlike this, the second pipe is inserted in the upper side on the lower side of the second through sleeve unit. Directional insertion work has a problem in that the operator cannot visually check the insertion depth of the second pipe.

In addition, when the upper end of the second pipe is inserted into the second through sleeve unit, this inserted part is hidden and cannot be visually confirmed from the outside. Ultimately, the operator relies on experience or sense of insertion depth of the second pipe. A situation arises where you must proceed.

Here, if the end of the second pipe is not completely inserted into the second through sleeve unit to the set depth, the sewage flowing along the second pipe will leak to the outside through the gap caused by failure to completely insert, causing a serious construction and installation problem. occurs.

However, there is currently no proposal for a pipe connection device or structure that allows workers to quickly and easily proceed with construction work while accurately checking the insertion depth of the second pipe, and to this day, installation is still done based on the worker's intuition. After construction, major problems such as leakage of sewage and bad odors occur frequently.

Here, the first pipe 31 is omitted and the interlayer pipe connecting device 100, specifically, as shown in FIG. 2, the lower end of the base body 200 is directly connected to the first pipe 31 without intervening the first pipe 31. When coupled to the through sleeve unit 10, the threads formed on the lower outer peripheral surface of the above-described piping fixture 220 and the base body 200 are also deleted, and the lower area of the base body 200 is the first through sleeve unit ( 10) It is formed in a straight line shape so that it can be inserted directly inside.

As shown in Figures 1 to 3, a lifting cylinder limiter 230 is continuously provided along the circumferential direction on the inner surface of the base body 200 to determine the lowest lowering position of the lifting cylinder 400, which will be described later. The lower end of the lifting cylinder 400, which is moving downward due to the rotation of the rotary cover 300, contacts the lifting cylinder limit ridge 230, thereby restricting further downward movement.

Next, as shown in FIGS. 1 to 5, the rotatable cover 300 is coupled to the base body 200 so as to be rotatable in the circumferential direction with respect to the base body 200.

As shown in FIGS. 3 and 4, an extension 240 having a relatively enlarged cross-sectional area and forming a locking protrusion 241 is provided at the top of the base body 200. The rotating cover 300 is connected to the extension portion 240 so that it can rotate only in the circumferential direction with respect to the expansion portion 240 without changing the relative position in the height direction with respect to the expansion portion 240 while being caught on the locking protrusion 241. is combined with

Elastic deformation is possible in the direction away from each other.

In an embodiment of the present invention, the catching hooks 321 are provided at the bottom of each of the plurality of cover pieces 323, and when the rotating cover 300 is coupled from the upper side to the lower side of the expansion portion 240, the catching hooks 321 By contact with the extension portion 240, the outer rotating covering portion body 322 is temporarily tilted outward, and when the contact between the side of the catching hook 321 and the expanding portion 240 is released, the outer rotating covering portion body ( 322) is restored to its shape inward, and at this time, the locking hook 321 is caught on the locking protrusion 241.

In this way, the individual cover pieces 323 are capable of elastic deformation and restoration above a certain level with respect to the outer rotating covering body 322 due to the cut holes 324 on both sides, and accordingly, the catching hook 321 The user can stably rotate the rotary cover 300 in the circumferential direction of the extension part 240 while it is caught by the locking protrusion 241 of the extension part 240.

Next, as shown in FIGS. 1 to 4 and FIG. 6, the lifting cylinder 400 is provided on the inside of the base body 200 to be able to move up and down in conjunction with the rotation of the rotary cover 300, so that the second pipe 32 It can be inserted and coupled into the second penetrating sleeve unit 20 by lifting it.

In an embodiment of the present invention, the lifting cylinder 400 includes a cylinder body 410 and a cylinder body extension 420.

As shown in FIGS. 3, 4, and 6, the cylinder body 410 has a vertical penetrating shape with a lifting thread 411 provided on the outer peripheral surface to be screwed to the rotating cover 300, and a second pipe at the bottom. A pipe end seating portion 412 is provided so that the lower end of the pipe (32) touches and rests.

Therefore, as shown in FIG. 6, when the user rotates the rotary cover 300 in one direction, the second pipe 32, whose lower end contacts and is seated on the pipe end seating portion 412 of the lifting cylinder 400, It can be inserted into the second penetrating sleeve unit 20 while moving upward. Conversely, when the user rotates the rotary cover 300 in the other direction, the lower end contacts the pipe end seating portion 412 of the lifting cylinder 400, and the seated second pipe 32 moves downward.

In addition, a concave groove is continuously provided on the outer surface of the cylinder body 410 along its circumferential direction, and within the concave groove is a leak-proof sealing portion for sealing between the base body 200 and the cylinder body 410. 413) is prepared.

The leak-proof sealing part 413 is made of a material with a certain level of ductility, such as rubber, silicon, etc., and is in close contact with the inner circumferential surface of the base body 200 when coupled to the cylinder body 410, thereby forming an inner surface of the second pipe 32. It is possible to prevent the odor of sewage flowing along from leaking to the outside through the gap between the base body 200 and the cylinder body 410.

The cylinder body extension 420 is provided to have an expanded ring-shaped cross section at the top of the cylinder body 410, and seals the space between the second pipe 32 and the lifting cylinder 400. ) A lifting leakage prevention sealing part is provided at the top of the lifting cylinder 400 to block the foul odor of sewage from leaking to the outside through the gap between the lifting cylinders (400).

For example, as shown in Figures 3 and 4, the lifting leakage prevention sealing part 415 is a ring-shaped single component made of a material such as rubber or silicon, and is located at the open upper step of the cylinder body expansion part 420. It may be provided in a location so as to be in close contact with the outer surface of the second pipe 32.

As another example, as shown in FIGS. 7 and 8, the lifting leakage prevention sealing part 416 may include a sealing material 418 and a sealing cover 419.

The sealing material 418 is seated on the step of the connection area between the cylinder body 410 and the cylinder body extension 420 and is shaped like a ring to enable close contact with the outer surface of the second pipe 32, and is made of a material such as rubber or silicon. It can be done.

In addition, the sealing cover 419 is made to have an approximately 'ㄷ' shaped channel-shaped cross section, and is coupled to the cylinder body extension 420 to secure the sealing material 418. The sealing cover 419 can be coupled to the top of the cylinder body extension 420 through forced press-fit. In a state in which the sealing cover 419 is coupled, the sealing material 418 is disposed inclined toward the inner space of the cylinder body 410, and when the second pipe 32 is inserted, it contacts the second pipe to form a cylinder body 410. As the body 410 is tilted toward the inner peripheral surface, the space between the cylinder body 410 and the second pipe 32 is sealed.

In an embodiment of the present invention, as shown in Figures 1 and 2, the first through sleeve unit 10 and the second through sleeve unit 20 are provided with fire-resistant foam material 11 in multiple stages on the inside. . Therefore, in the event of a fire, the pipe (especially the second pipe), which melts or burns due to high-temperature heat and falls, and a portion of the fireproof foam installed adjacent to it, fall together and break away from the penetrating sleeve and the floor (or wall) between floors of the building. Even if this phenomenon occurs, the remaining fire-resistant foam (in the drawing, the fire-resistant foam installed relatively on the upper side) expands normally and provides a structure that can close the mounting hole in the floor between floors, providing stable fire resistance performance.

Above, the characteristic parts of the present invention have been described, and the present invention allows the user to insert the second pipe 32 into the second through sleeve unit 20 while rotating the rotary cover 300, and this lifting method The second pipe can be easily inserted into the second penetrating sleeve unit 20 to the maximum depth through insertion, and the operator can easily check the completion of insertion to the maximum depth.

To elaborate, when the user rotates the rotary cover and the rotary cover 300 can no longer rotate, the upper end of the second pipe 32 is inserted as much as possible into the pipe insertion groove of the second through sleeve unit 20. You can easily check that it has been fully inserted to the desired depth. If the second pipe 32 is not completely inserted into the pipe insertion groove of the second through sleeve unit 20, in severe cases, sewage may flow between the second through sleeve unit 20 and the second pipe 32. A major disaster may occur where water leaks through a gap.

In this way, the present invention can reliably insert the second pipe 32 into the second penetrating sleeve unit 20 and the user can easily confirm the fully inserted state, preventing construction defects from occurring at the construction site of an actual building. It can prevent claims from occurring due to leakage of sewage and bad odors.

In addition, the state of insertion of the upper end of the second pipe 32 into the second penetrating sleeve unit 20 at the actual work site is not only a part that cannot be visually confirmed by the field construction worker, that is, it is obscured and cannot be confirmed with the naked eye. The complete insertion degree cannot be easily confirmed. However, in the present invention, as described above, when the rotary cover 300 rotates and no longer rotates, the upper end of the second pipe 32 is connected to the second through sleeve. Since it is inserted as much as possible inside the unit 20, workers can easily check the degree of pipe insertion at the construction site.

Hereinafter, an interfloor piping connecting device 100 according to another embodiment of the present invention will be described, and redundant description of the same configuration as the above-described embodiment will be omitted.

As shown in FIG. 9, the interfloor piping connection device 100 according to another embodiment of the present invention includes a first penetration sleeve unit 10 installed to be embedded in a low-rise interfloor and a second penetration sleeve unit 10 installed to be embedded in a high-rise interfloor. This is to connect the sleeve unit 20 to the first pipe 31, the second pipe 32 and the connection socket 510.
