Description

  The present invention relates to a drainage pipe support structure that supports a drainage pipe so as to be suspended from a lower surface of a slab, and can enhance its robustness.

Conventionally, in reinforced concrete buildings, drainage pipes are arranged through through-holes established in slabs. At this time, a support that supports the drainage pipe so as to be sandwiched from both sides is used. In Patent Document 1 (Japanese Patent Laid-Open No. 2001-348926), even when the drainage pipe is directly supported by a support (support band), noise during drainage is not easily transmitted to the slab surface. A vibration isolator for a drainage pipe support band is described in which a vibration isolator made of a material having both vibration absorption and fire resistance is interposed in the support band.
JP 2001-348926 A

  However, the drainage pipe support band described in Patent Document 1 needs to be tightened with bolts and nuts at a plurality of locations in a state in which the blade plate portion connected to the lower end of the turnbuckle is sandwiched at both ends in order to sandwich the piping. . For this reason, labor and work time have been required for the tightening operation in a state where the support band is wound around the drainage pipe. Further, in an environment where workability on the lower surface of the slab is poor, there is also a problem that a long time work with an unreasonable posture is required for tightening with bolts and nuts.

  In addition, the position of the drainage pipe relative to the slab may be shifted somewhat, and the horizontal position of the drainage pipe support band attached to the drainage pipe and the suspension bolt connected to the lower surface of the slab in advance may be shifted. Mounting could be difficult due to misalignment.

  The present invention has been made in consideration of the above-mentioned matters, and its purpose is to simplify the fixing of the drainage pipe to the lower surface of the slab, which is easy to work and can be manufactured at low cost. It aims at providing the support structure of the drainage pipe of composition.

  In order to achieve the above object, the present invention provides a pair of supports for sandwiching a drainage pipe from both sides, and engaging the both supports in a state where the drainage pipe is sandwiched by this support to maintain the sandwiched state. Provided is a drainage drainage pipe support structure comprising a clip and a substantially bar-like hanging tool attached to a lower surface of a slab so as to be suspended from a lower surface of the slab. (Claim 1)

  In the drainage pipe support structure, since the clip is attached to the support with the drainage pipe sandwiched by both supports, the sandwiched state by the support can be maintained. It can be attached so as not to be displaced. Moreover, since a support body is connected with the hanging tool attached so that it may hang down on a slab lower surface, a drainage pipe can be fixed to the predetermined position of a slab lower surface.

The support body includes a semicircular abutting portion that abuts the half circumference of the outer peripheral surface of the drainage pipe, and a flat plate portion that extends at both ends of the abutting portion, and the suspension member is coupled to the flat plate portion. It is preferable to form a connecting portion for the purpose. The support is preferably made of a metal having excellent corrosion resistance, and is made of an alloy having excellent corrosion resistance and rigidity, such as stainless steel. Moreover, it is preferable that the contact part with a drain pipe is provided with the buffer surface which consists of resin provided with elasticity.

  The clip is a plate-shaped body made of a metal having the same rigidity as the support body or higher rigidity than the support body, and is curved in a substantially cross-sectional shape, and the both supports are brought into close contact with each other by engaging with the support body. It is preferable that it can be made.

  The suspension is screwed and connected to an insert hardware (embedded female thread) whose upper end is buried in a suitable position on the lower surface of the slab, and a buckle for adjusting the height position of the support suspended by the suspension It is preferable to provide.

  In the case where the both supports are provided with a hinge portion that connects the one end side so as to be openable and closable and a clip engagement portion that engages the clip on the other end side (Claim 2), one clip is provided. Since the support body can be held in a sandwiched state by engaging with the clip engaging portion, the drainage pipe using the support body can be supported more easily. Moreover, since both support parts are connected by the hinge part, management becomes easy compared with the case where these are isolate | separated.

  In a state in which the drainage pipe is sandwiched between the two supports, a curved portion is formed between the two supports so that a long hole can be sandwiched between the supports at a different angle. When it has a flange part larger than a hole (Claim 3), the connection part of a hanging tool and a support body is a long hole, and has the freedom degree connected in an oblique direction. Moreover, since a flange part is larger than a long hole, the connection state of a support body and a suspension tool is stabilized.

  In the case where the suspension tool is a suspension bolt that has a male thread portion that is screwed into a female thread portion that is embedded in the lower surface of the slab and is bent just before being connected to the support body (Claim 4), the suspension tool is bent. By doing so, the threaded portion after the support and the hanging tool are connected is prevented from loosening.

  According to the support structure of the drainage pipe having the above-described structure, the support body is arranged so as to sandwich the drainage pipe from both sides thereof, and the clip is sandwiched between these support bodies, so that an extremely simple operation such as sandwiching using the clip is performed. Thus, the support can be fixed at a predetermined position of the drainage pipe. At this time, the position of the support can be fixed by engaging the hanging tool at the same time.

  In addition, in the case where a hinge portion is provided on one end side of the support body and a clip engagement portion is provided on the other end side, the sandwiched state by the support body can be achieved by a simple operation of simply engaging one clip with the clip engagement portion. Since it can be held, workability is even better. Since both the support portions are connected by the hinge portion, the number of parts is reduced, and management becomes easier accordingly.

  In the case where a long hole is formed in the support, there is a degree of freedom due to the long hole in the connection state of the hanger and the support, and it is possible to easily cope with the positional deviation between the hanger and the drainage pipe. Moreover, since the long hole can pinch the hanging tool by pinching with both supports, and the flange portion is larger than the long hole, the connection state of the support and the hanging tool can be stabilized.

  When the suspension is a suspension bolt that is screwed and connected, and is bent just before connection with the support, the connection between the support and the suspension should be done to prevent the screwed portion from loosening. Can do.

FIG. 1 is an overall configuration diagram showing the assembled state of the drainage pipe support structure 1. FIG. It is a figure which shows the principal part structure of the support structure 1 of a soot pipe.

  In FIG. 1, reference numeral 2 denotes a drainage pipe through which drainage flows, 3 denotes a pair of supports sandwiching the drainage pipe 2 from both sides, and 4 denotes both supports 3 with the drainage pipe 2 sandwiched by the support 3. A clip that engages and holds the sandwiched state, 5 is a slab that attaches the drainage pipe support structure 1, 6 is a substantially rod-like shape that is attached to the lower surface of the slab 5 and the lower part is connected to the support 3. It is a hanging tool.

  The drainage pipe 2 includes an upper drainage pipe 2c having a joint 2b connected to the drainage horizontal branch pipe 2a, and a lower drainage pipe 2d connected to the lower end of the upper drainage pipe 2c. In addition, an enlarged diameter portion 2e into which the lower end portion of the upper drainage pipe 2c can be inserted is formed at the upper end part of the lower drainage pipe 2d.

  As shown in FIG. 2, the support 3 includes a semicircular contact portion 3a that contacts the half circumference of the outer peripheral surface of the drainage pipe 2, and flat plate portions 3b and 3c that extend at both ends of the contact portion 3a. And connecting portions 3d and 3e for connecting the suspension 6 to the flat plate portions 3b and 3c. The support 3 is made of a metal such as stainless steel having excellent corrosion resistance and mechanical strength. Reference numeral 10 denotes a pair of shock-absorbing materials that are attached to the abutting portion with the drainage pipe 2 and are made of an elastic resin. The cushioning material 10 forms a cushioning surface at the abutting portion with the drainage pipe. .

  Further, the support bodies 3 and 3 are provided with a hinge portion 3f for connecting them in an openable and closable manner at one end side, and a clip engaging portion 3g for engaging the clip 4 on the other end side, and supporting these The connecting portions 3d and 3e have a long shape so that the hanging tool 6 can be sandwiched between the supports 3 and 3 while the drainage pipe 2 is sandwiched between the bodies 3 and 3. Curved portions 3h and 3i that are curved to form holes are provided.

  The clip 4 is formed by bending a substantially band-shaped metal made of a metal having elasticity, and the interval d2 is narrower than the interval d1 of the clip engaging portion 3g in a state where the supports 3 and 3 are closed. The opening 4a is curved to have a substantially vertical cross-sectional shape, and is a shape to which a force for pressing the support bodies 3 and 3 in the sandwiching direction can be applied in the engaged state. Further, widening guide portions 4b and 4c are formed in the opening 4a.

  The slab 5 penetrates the drainage pipe 2 and forms a through-hole 5a having a diameter larger than that of the drainage pipe 2. A pair of insert hardware 11 is embedded at positions facing each other around the through-hole 5a. Thus, an embedded female screw portion 6a is formed so that the hanging tool 6 can be screwed together. Reference numeral 12 denotes a mortar that fills the space between the through hole 5a and the through drainage pipe 2 in a state where the drainage pipe 2 is passed through the through hole 5a.

  The hanging tool 6 of the present embodiment is, for example, a rod-like bolt having a male screw formed on its entire length, and a male screw part 6b formed on the upper end of the hanging tool 6 is screwed and connected to the embedded female screw part 6a. The lower end portion of the hanging tool 6 is provided with a washer 6c and a nut 6d. The hanging tool 6 has a flange portion larger than the long holes 3e and 3F at the lower end portion by the washer 6c and the nut 6d. In addition, it is preferable to provide a locking nut (not shown) that prevents the nut 6d from rotating further below the nut 6d that forms the flange portion and is screwed and connected to the hanger 6.

  Hereinafter, an operation process for fixing the position of the drainage pipe 2 using the drainage pipe support structure having the above-described configuration will be described.

In a state where the drainage pipe 2 is disposed in the through-hole 5a opened in the slab 5, and the gap between the drainage pipe 2 and the through-hole 5a is filled with mortar 12, a pair of suspensions are attached to the pair of female screw portions 6a. The tool 6 is screwed and connected, and the hanging tools 6 and 6 are bent inward so that the position of the lower end portion thereof is arranged in accordance with the position of the drainage pipe 2.

  Subsequently, the lower end portion of the bent hanging tool 6 is sandwiched by the connecting portions 3d and 3e, and at the same time, the drainage pipe 2 is sandwiched by the curved portion 3, and the clip 4 is engaged with the clip engaging portion 3g. . That is, both the connection of the hanging tool 6 and the support portion 3 and the sandwiching of the drainage pipe 2 by the support portion 3 can be performed at a time by a simple operation of simply engaging the clip 4 with the clip engagement portion 3g. Because it can, work efficiency is good. Further, since the interval d2 between the openings of the clip 4 is narrower than the interval d1 between the clip engaging portions 3g, the support 3 can be urged by the clip 4 in the sandwiching direction.

  At the same time, since the hanging tool 6 bends inward at this time, the hanging tools 6 and 6 do not rotate with respect to the female screw portion 6a after installation, and the mounting state can be stabilized. Further, in the drainage pipe support structure 1 of the present embodiment, the hanging tool 6 is a rod-like bolt having a male screw formed on the entire length thereof, so that a washer 6c and a nut 6d are attached from the lower end of the hanging tool 6. Thereby, the position of the flange part formed by these members 6c and 6d can be adjusted, and thereby the height position of the support 3 can be stabilized.

  The washer 6c and the nut 6d are attached after the drainage pipe 2 is sandwiched by the support 3, and the height of the support 3 is finely adjusted to be a position immediately below the enlarged diameter portion 2e. However, the drainage pipe 2 may be sandwiched by the support 3 after the washer 6c and the nut 6d are first attached.

  Moreover, since the hanging tool 6 is clamped by the connection parts 3d and 3e formed in the said long hole, since it can connect even if an attachment angle becomes diagonal, there exists a freedom degree. Therefore, even when the position of the hanging tool 6 and the position of the drainage pipe 2 are shifted, the drainage pipe 2 can be attached to the lower surface of the slab.

  FIG. 3 is a view showing a configuration of a drainage pipe support structure 1A according to the second embodiment. As shown in FIG. 3, the hanging tool 6 'may have a flange 6e formed in advance at the lower end thereof. In this case, the hanging tool 6 'may be any one in which the male screw 6b is formed only at the portion screwed and connected to the female screw portion 6a. Since other configurations are the same as those in the first embodiment, the same reference numerals are given to avoid redundant description.

  Moreover, in each embodiment mentioned above, the one clip 4 was attached to the clip engaging part 3g formed in one place of the other end part of the support body 3 by providing the hinge part 3f in the one end part of the support body 3. FIG. The drainage pipe 2 can be sandwiched by the support body 3 simply by attaching it, but the support body 3 also forms a clip engaging portion at one end thereof, and the clip 4 is inserted at both end sides sandwiching the contact portion 3a.
