Description

  The present invention, for example, in a multi-layered building such as an apartment building or a commercial building such as a mid-to-high-rise apartment, a piping unit used as a standing pipe for water supply / hot water supply, etc., which is stored in a pipe shaft provided through each floor The present invention relates to a vertical pipe method using the above.

In multi-layer buildings such as middle- and high-rise apartment buildings and commercial buildings, when installing main pipes such as water and hot water as standing pipes indoors, one layer (1st floor) or 2 to 2 A straight pipe that is the main pipe part corresponding to three layers is adjusted to a predetermined length, and is manually connected sequentially through pipe joints, etc., and fixed to the building frame using fixing brackets. It is.
However, many members and installation tools such as straight pipes and pipe joints as piping materials must be transported to the construction site on each floor, and the more expensive the building, the more time-consuming and costly work is required. It was.

  Therefore, a piping method using a piping unit manufactured by connecting a flexible piping material cut to the length of one layer of a building to a length of a plurality of floors via a branch joint has already been proposed. (See Patent Documents 1 and 2).

  That is, in the piping method using the above piping unit, as shown in FIG. 19, the piping unit 100 is wound around a reel 200, and the entire reel 200 is carried into a construction site. The piping work is performed by lifting upward through the through sleeve 310 provided in the slab 300, so that the connection work between the pipe joint and other piping material in the field is reduced as much as possible.

However, in a housing complex or the like, the diameter of the penetration sleeve 310 is remarkably limited due to the penetration of the fire prevention compartment, and the branch pipe connection portion 120 formed by the branch joint 110 exists so as to protrude from the side surface of the piping unit 100. Therefore, when trying to pipe a standing pipe of a multi-layered building as described above using the pipe unit 100 having a nominal diameter of 20A or more, the through sleeve in which the branch pipe connecting portion 120 is provided in the floor slab 300 When passing through 310, it tends to catch on the peripheral edge of the penetration sleeve 310.
When the pipe unit 100 is further pulled up in a state where the branch pipe connection part 120 is caught by the peripheral edge part of the through sleeve 310, the connection of the branch joint 110 is disconnected or the pipe unit 100 is damaged, resulting in the occurrence of an occupational accident. Concerned.

  The vertical pipe method according to claim 4 of the present invention (hereinafter referred to as “the vertical pipe method of claim 4”) is the guide pipe method according to any one of claims 1 to 3. The inner end edge of the short pipe on the side of the piping unit insertion port is chamfered.

In the present invention, it is preferable that the guide short pipe is not more than a weight (for example, 15 kg or less) such that the total weight of the obtained guide cylindrical body can be easily supported by one operator.
As long as the material of the guide short tube can withstand the through-tube, any material such as metal, resin or paper is not restricted.
The outer diameter of the guide short pipe is set to be equal to or smaller than the inner diameter of the through sleeve, and the wall thickness is preferably thin from the viewpoint of securing the cross-sectional area in the guide pipe.
Moreover, it is desirable to apply a lubricant that does not soak a flexible resin typified by polyethylene, such as a silicone lubricant, to the inner surface of the guide short tube.

  As described above, in the vertical pipe method according to claim 1, the flexible long pipe unit is passed from the upper floor to the lower floor through the through sleeve provided in the floor slab of each floor of the multilayer building. This is a vertical pipe method for connecting vertical pipes. A guide short pipe whose outer diameter is smaller than the through-sleeve diameter and whose inner diameter is larger than the pipe unit is connected to the lowermost floor for guiding the lower guide short pipe. A guide that is successively received from below by a pipe and that reaches the upper end of the uppermost floor through sleeve that is piped at the upper end, and that forms a guide cylindrical body having a gap for taking out the leading wire material on the lowermost floor side Cylindrical body forming step and leading linear material insertion step of dropping the leading linear material into the guide cylindrical body from the uppermost floor to the lowermost floor and inserting the leading linear material into the guide cylindrical body And on the top floor or the bottom floor After fixing one end of the piping unit to one end of the leading wire, pull the other end of the leading wire on the lowermost floor or the uppermost floor to guide the cylindrical body from the uppermost floor to the lowermost floor A piping unit insertion process for inserting the piping unit into the pipe, a piping unit fixing process for fixing a part of the piping unit to the building frame at least on the uppermost floor side, and a guide short for forming the guide cylindrical body from the lowermost floor side And a guide short pipe removing step for removing the pipes in order, so that the pipe unit can be easily and safely piped as a standing pipe.

That is, when the piping unit is suspended from the uppermost floor side to the lowermost floor side, or when the piping unit is pulled up from the lowermost floor side to the uppermost floor side, the piping unit passes through the guide cylindrical body. Even if there are protrusions such as branch parts, these protrusions are not caught on the edge of the penetration sleeve.
Therefore, it is only necessary to arrange personnel on the uppermost floor side and the lowermost floor side, and the work cost can be reduced.

In the vertical pipe method according to claim 2, the upper and lower guide short pipes are fixed with the adhesive tape, so that the guide cylindrical body shape can be firmly held, and if the adhesive tape is removed, the guide short pipe is replaced with another guide. It can be easily removed from the short pipe and the guide short pipe can be removed easily.
Further, since only the adhesive tape is removed at the time of removal, the guide short tube is not damaged. Therefore, the guide short pipe can be used many times for this vertical pipe method.

  In the vertical pipe method of claim 3, the guide short pipe is formed by holding two divided bodies cut into two along the pipe axis in a short pipe shape using an adhesive tape. By removing the adhesive tape, it is easily split into two. Therefore, even if the piping unit is in the inserted state, the guide short pipe removing operation can be easily performed.

  In the vertical pipe piping method according to claim 4, since the inner end edge of the short pipe for guide on the side of the piping unit insertion port is chamfered, the pipe shaft of the upper and lower guide short pipes at the connecting portion of the upper and lower guide short pipes Even if they are shifted and a step is generated on a part of the inner wall surface, the chamfered portion prevents the protrusion on the outer wall surface of the piping unit from being caught by the step.
