More particularly, the present invention relates to an attachment body for wiring / piping that is often attached to the attached body in parallel.

FIG. 20 shows an attachment body for wiring and piping of this type that is conventionally embedded in a concrete housing, with an end cover as an application example.
In FIG. 20, an attachment body 41 for wiring and piping applied to the end cover is disposed in a concrete housing 48 such as a double ceiling, and is roughly cut by a diagonal surface into a cylinder having two bottom walls. The diagonal surface of the cylinder is flush with the concrete surface and opens outward. A wiring / piping material protection tube 47 is attached to one end of the mounting body 41 via a connector (not shown), and a portion corresponding to the side wall portion of the cylinder is an inclined side wall 42. . Further, a nail is attached to the center fixing portion 43 provided at the substantially central portion of the upper surface of the inclined side wall 42 or the side fixing portions 45 provided on both sides of the contact plate portion 44 with which the formwork 31 for placing concrete contacts. A fixture 32 such as the above is attached so that the attachment body 41 is fixed to the mold 31.

  The mounting body 41 thus constructed is embedded in the concrete frame 48 with the mounting body 41 placed on the formwork 31 in a state in which the rebars 33 and the formwork 31 arranged vertically and horizontally are installed. The fixing tool 32 is inserted into the insertion hole 46 of the central fixing part 43 or the side fixing parts 45 on both sides, and the fixing tool 32 is driven into the mold 31 to fix the attachment body 41. Next, the concrete is cast and the mold 31 is removed after the concrete is hardened.

  However, when mounting a plurality of conventional mounting bodies 41 including the mounting bodies described in Japanese Patent Laid-Open No. 11-336952 in parallel in the concrete frame 48, a number of supporting bodies 41 are disposed above the mounting body 41. Since the steel reinforcing bars 33 are arranged vertically and horizontally and the work space is narrowed, the attachment of the attachment body 41 to the mold 31 is very troublesome. That is, with reference to FIG. 21, among the three attachment bodies 41, for the two attachment bodies 41 on both the left and right sides arranged at the approximate center of the space surrounded by the longitudinal and lateral rebars 33, the operator It is possible to hold the attachment body 41 with one hand and hit the fixing tool 31 with the other hand using a tool such as a hammer. However, the attachment body 41 arranged in the middle includes the reinforcement 33 in the upper part. Therefore, when the fixing tool is hit, the narrow attachment between the reinforcement 33 and the formwork 31 is handed from the lateral direction. Must be inserted and the attachment body 41 is held, and the attachment body 41 must be fixed in an unreasonable posture. For this reason, it is difficult to work, and it may be impossible to fix at a predetermined position due to displacement. In particular, since the rebar rebar 33 is normally arranged in two upper and lower stages, the work is more difficult.

  In addition, when attaching a plurality of conventional attachment bodies 41 to the mold frame 31 in parallel, for example, when attaching to the mold frame 31 using the side fixing portions 45 provided on both sides, For each body 41, it was necessary to attach a fixing tool 32 such as a nail or a screw to the side fixing portions 45 on both sides. In addition, since a large number of fixtures 32 are required to be mounted, a lot of work time is required.

  Therefore, the present invention is embedded in a concrete case, and can be fixed to an attached body with good workability even in a narrow space where a rebar or the like is interposed when attaching to a formwork in placing concrete. At the same time, it is an object of the present invention to provide an attachment body for wiring and piping that can reduce the number of fixtures to be fixed to the mold and reduce the work time for the attachment.

It is inserted into the mounting body 1 from the side and drawn into the wiring / piping material protection pipe.

  The attachment body 1 is roughly shaped by cutting a cylinder having a bottom wall into two diagonal surfaces, and the diagonal surface of the cylinder is flush with the concrete surface as shown in FIG. Thus, the opening surface 2 is opened outward. A portion corresponding to the bottom wall of the cylinder, which is one end side of the mounting body 1, is formed with a mounting wall 3 and is inclined obliquely upward from the opening surface 2 so that the connector is mounted. A portion corresponding to the side wall portion of the cylinder is an inclined side wall 4 of the mounting body 1. An attachment hole 5 through which one end side of the connector is inserted is provided at the center of the attachment wall 3, and the attachment wall 3 is sandwiched between a flange portion and a nut provided in the connector. Is supposed to be attached. The attachment hole 5 corresponds to a holding portion in claims.

  A central fixing portion 6 through which a fixing tool 32 such as a nail or a screw is inserted is provided at a substantially central portion of the top of the inclined side wall 4. As shown in FIG. 6, the center fixing portion 6 is integrally provided with a guide pin 7 that hangs in an orthogonal direction toward the opening surface 2, and the fixing tool 32 is inserted through the guide pin 7. The through-hole 8 to be penetrated and can be broken off at the connecting portion with the inclined side wall 4. That is, when the guide pin 7 is fixed to the mold 31 as an attached body, the guide pin 7 is fixed in a direction orthogonal to the mold 31 by guiding the mounting direction of the fixture 32 to the mold 31. In accordance with the removal of the formwork 31 after placing the concrete, it is broken off at the joint with the inclined side wall 4 and removed together with the fixture 32. The attachment wall 3, the inclined side wall 4, and the abutting plate portion 9 described later correspond to a main body portion of the claims.

  In addition, a contact plate portion 9 that contacts the mold 31 is formed on the outer peripheral portion of the opening surface 2 of the attachment body 1, and a fixing tool 32 such as a nail is attached to a substantially central portion on both sides thereof. The substantially square plate-like side fixing part 10 and the side fixing part 11 are provided so as to protrude laterally. The side fixing part 10 and the side fixing part 11 are respectively provided with an insertion hole 12 and an insertion hole 13 through which the fixing tool 32 is inserted. In addition, although the fixing | fixed part for fixing the said attachment body 1 to the formwork 31 is provided in three places, the said center fixing | fixed part 6, the side fixing | fixed part 10, and the side fixing | fixed part 11, Usually, the fixture 32 is inserted into one place of the center fixing portion 6 and fixed to the mold 31. However, the guide pin 7 of the center fixing portion 6 has already been broken off and removed, for example, when the mounting body 1 that has been once embedded in the concrete casing and then removed for reuse is embedded in another concrete casing. Therefore, it is fixed using the side fixing part 10 and the side fixing part 11.

  Further, a non-contact engaging portion 14 having a substantially square plate shape, which is a feature of the present invention, is integrally provided adjacent to the side fixing portion 10 in the longitudinal direction of the attachment body 1. The non-contact engagement portion 14 is spaced apart upward from the upper surface of the mold 31 and is in a non-contact state. Further, a substantially square plate-like contact engaging portion 15 which is a feature of the present invention is integrally provided adjacent to the opposite side fixing portion 11 in the longitudinal direction of the attachment body 1. The contact engagement portion 15 is in contact with the upper surface of the mold 31. The non-contact engagement portion 14 and the contact engagement portion 15 correspond to the engagement portions in the claims.

  First, as shown in FIG. 1 and the like, the non-contact engagement portion 14 is at a position where the lower surface 16 is spaced upward from the opening surface 2 by a height h1. A cylindrical convex portion 17 that projects vertically downward is provided substantially at the center of the lower surface 16. On the other hand, the contact engagement portion 15 is provided at a position corresponding to the non-contact engagement portion 14, and the lower surface thereof is at the same height as the opening surface 2, as shown in FIG. The upper surface 18 is located above the opening surface 2 by a height h2. A concave portion 19 into which the convex portion 17 is fitted is provided at the approximate center of the upper surface 18 corresponding to the convex portion 17 of the non-contact engagement portion 14. The recess 19 is formed as a through hole or a non-through hole.

  Further, the height h2 is set to be the same as the height h1 of the non-contact engagement portion 14. Accordingly, as shown in FIG. 7, the convex portion 17 of the non-contact engagement portion 14 of one attachment body 1 and the concave portion 19 of the contact engagement portion 15 of the other attachment body 1 are fitted to each other. When the non-contact engagement portion 14 and the contact engagement portion 15 are engaged, the lower surface 16 of the non-contact engagement portion 14 is adjacent to the side contact portion 10 adjacent to the non-contact engagement portion 14. Or the bottom surface 16 of the non-contact engagement portion 14 floats above the top surface 18 of the contact engagement portion 15. Without mounting, the mounting body 1 is placed on the upper surface 18 of the abutting engagement portion 15, and the both attachment bodies 1 are arranged side by side in a state where they are fit in the height direction. The entire lower surface 16 of the non-contact engagement portion 14 may be placed on the upper surface 18 of the contact engagement portion 15, or a part thereof may be placed. The lower surface 16 of the non-contact engagement portion 14 corresponds to the contacted portion of the claims, and the lower surface of the contact engagement portion 15 corresponds to the contact portion of the claims.

Next, the positional relationship between the non-contact engagement portion 14 and the contact engagement portion 15 will be described with reference to FIGS.
The distance h3 from the center of the convex portion 17 of the non-contact engagement portion 14 to the base line A in the width direction passing through one end on the attachment hole 5 side as the holding portion of the mounting body 1, and the concave portion of the contact engagement portion 15 The distance h4 from the center of 19 to the base line A is set to be the same. Therefore, when the plurality of attachment bodies 1 are fixed in parallel on the mold 31, as shown in FIG. 8, the base lines A of the attachment bodies 1 are aligned and the attachment bodies 1 are aligned. Become. As shown in FIG. 8, the side fixing part 10 and the side fixing part 11, when the plurality of attachment bodies 1 are fixed in parallel to the mold frame 31, The contact fixing portion 15 is superposed vertically and engaged.

  Further, the outer side surface 10a of the side fixing portion 10 shown in FIG. 1 is a side surface of the abutting plate portion 9 facing the other mounting body 1 when the plurality of mounting bodies 1 are fixed in parallel to the mold 31. It protrudes outward with an amount of protrusion that is in contact with or very close to 9a. Alternatively, the outer side surface 11a of the side fixing portion 11 and the outer side surface 15a of the contact engaging portion 15 are in contact with or closely adjacent to the side surface 9b of the opposing contact plate portion 9 of the other mounting body 1. It protrudes outward. Therefore, as shown in FIG. 8, when the engaging portions of the attachment bodies 1 are engaged with each other, the side fixing portion and the outer side surface of each engaging portion are in contact with the side surface of the abutting plate portion 9. Due to the contact, the mounting body 1 is restricted from rotating in the horizontal direction, that is, in the same plane direction as the opening surface 2 around the engaging portion of the convex portion 17 and the concave portion 19, and the mounting bodies 1 are aligned in parallel. Kept in a state.

  Next, the work of fixing the plurality of attachment bodies 1 in parallel on the mold 31 will be described with reference to FIG. Although FIG. 8 shows a case where three attachment bodies 1 are provided side by side, the case where two or four or more attachment bodies 1 are provided can also be performed in the same manner.

  In FIG. 8, the rebars 33 are arranged at predetermined intervals vertically and horizontally above the mold 31 with a predetermined distance. In this bar arrangement state, even if the placement location of the three attachment bodies 1 is adjusted, the gap between the rebars 33 is small, so in any attachment body 1, for example, in FIG. There is a lateral rebar rebar 33 above the mounting body 1, which becomes a hindrance to the fixing work, and the operator cannot hold the mounting body 1 by extending his hand downward. A hand must be inserted and held in the gap between the mounted body 31 and the rebar 33. Accordingly, it is very troublesome to sequentially fix and fix the fixture 32 on the mold 31 as it is. On the other hand, since there is no support bar 33 on the upper side of the attachment bodies 1 on both sides, the operator extends the hand directly from above the attachment body 1 and holds the attachment body 1 in the fixing work. can do. Therefore, first, the fixing of the left attachment body 1 in FIG. 8 is started.

  In fixing the left attachment body 1 to the mold 31, a fixing tool 32 such as a nail is inserted into the central fixing part 6 while being guided by the guide pin 7, and the head of the fixing tool 32 is inserted with a tool such as a hammer. Can be done by hitting. When the left mounting body 1 is a reused product and the guide pin 7 has already been removed, the side fixing parts 10 on both sides of the mounting body 1 are not used. The fixing tool 32 can be inserted and fixed in the insertion hole 12 and the insertion hole 13 of the side fixing part 11. Hereinafter, the same applies to the fixing to other attachment bodies 1.

  In this way, when the left attachment body 1 is fixed to the mold 31, the center attachment body 1 is disposed slightly adjacent to the lower attachment body 1 from an oblique lateral direction while slightly floating from the mold 31. At this time, the convex portion 17 of the non-contact engagement portion 14 of the central attachment body 1 is fitted into the concave portion 19 of the contact engagement portion 15 of the left attachment body 1, so The contact engagement portion 14 is engaged with the contact engagement portion 15 of the left attachment body 1.

  In this engaged state, the outer side surface 10a of the side fixing portion 10 of the central mounting body 1 is in contact with or in close proximity to the side surface 9a of the opposing abutting plate portion 9 of the left mounting body 1, or The outer side surface 11a of the side fixing portion 11 of the left mounting body 1 and the outer side surface 15a of the contact engaging portion 15 are in contact with or very close to the side surface 9b of the abutting plate portion 9 of the central mounting body 1 facing each other. To do. As a result, due to the abutment of the lateral fixing part and the outer surface of each engaging part and the side surface of the abutting plate part 9, the central mounting body 1 can pivot the engaging part between the convex part 17 and the concave part 19. Further, it is restricted from rotating with respect to the left attachment body 1 in the horizontal direction, that is, in the same plane direction as the upper surface of the mold 31. As a result, the central attachment body 1 is held in a certain parallel state with respect to the left attachment body 1 and temporarily fixed at a predetermined position of the mold 31. Thereby, the operator does not need to hold | maintain the center attachment body 1 by hand during a fixing operation, and can save the effort.

  Once the central mounting body 1 is temporarily fixed, the operator can insert the fixing tool 32 into the central fixing portion 6 without holding the central mounting body 1 by hand and hit the mold 31 with a hammer. Thus, the central attachment body 1 is fixed, that is, permanently fixed to the mold 31. When a reusable product is attached as the central attachment body 1 or when the rebar 33 is directly above the central fixing portion 6, the fixing tool 32 cannot be inserted into the central fixing portion 6. For example, the side fixing part 10 and the side fixing part 11 on both sides can be inserted.

  Here, when fixing the central attachment body 1, since the gap between the left attachment body 1 and the central attachment body 1 is small, it is preferable that the center attachment body 1 is driven through a rod-shaped tool. That is, it can be performed by abutting the tip of the rod-shaped tool against the head of the fixture 32 and hitting the other end of the tool with a hammer or the like. Alternatively, as shown in FIGS. 9 to 11, a nailing hammer 34 can be used for simple driving. As shown in FIG. 9, the nail hammer 34 drops in the direction of the arrow when the nail is inserted from the side insertion port 34a, so that the handle 34b is pushed down as shown in FIG. It can be easily struck even in a narrow space as shown in FIG.

  When the left and center attachment bodies 1 are fixed in this way, the right attachment body 1 in FIG. 8 is fixed. Since the right attachment body 1 can be fixed to the mold 31 in the same manner as the central attachment body 1, the description thereof is omitted.

  By the way, the fixing of the center mounting body 1 and the right mounting body 1 in FIG. 8 is performed by first fixing the left mounting body 1 to the mold, and then fixing the center mounting body 1 and the right mounting body 1 in order. Although it is performed in the procedure of temporarily fixing to the body 1 and hitting the fixing tool 32 to perform the main fixing, it is not limited to this. First, the engaging portions of all three attachment bodies 1 are engaged. It is also possible to place all three pieces on the mold 31 in a temporarily fixed state, and then perform permanent fixing using the fixing tool 32 sequentially. In this case, similarly, after the left side mounting body 1 is first fixed, the center mounting body 1 and the right side mounting body 1 are temporarily fixed. The fixing tool 32 can be hit on the frame 31 to be permanently fixed.

  If the upper attachment body 1 is permanently fixed to the central attachment body 1, the contact engagement portion 15 of the central attachment body 1 is not contacted with the upper attachment body 1 placed on the contact attachment portion 15. Since the upward movement is prevented by the portion 14, when it is stably held on the formwork 31 without performing the main fixing by the fixing tool 32, the temporary fixing also serves as the main fixing. Thus, the fixing using the fixing tool 32 can be omitted.

  Thus, according to the attachment body 1 of this embodiment, when attaching a plurality of attachment bodies 1 to the attachment body in parallel, the operator needs to hold the next attachment body with one hand. Therefore, it can be attached to the mold 31 with good workability. In addition, the number of fixtures 32 can be reduced by holding the engaging portions to be engaged, and accordingly the working time can be shortened.
