Description

  TECHNICAL FIELD The present invention relates to a dowel post-insertion type embedded metal used for supporting piping or the like on a ceiling surface, a wall surface or the like in a concrete building.

Conventionally, an embedded metal fitting is used to fix a support fitting that supports a heavy object such as a pipe and an electric wire on a ceiling surface or a wall surface in a concrete building.
As shown in FIG. 6 (1), the embedded metal object 1 has a stud divel 4 attached to a metal plate 3 formed in a rectangular shape and having an attachment hole 2 by welding. Alternatively, Patent Document 1 discloses that a U-shaped fixing member is fixed to an embedded metal.

    When this embedded metal 1 is installed in a concrete building, as shown in FIG. 6 (2), the embedded metal 1 with the stud gibber 4 welded in advance is installed at the installation location of the concrete building and embedded in the concrete layer. After lightly fixing to the reinforcing bar 5 or the like, the concrete 6 is placed and the embedded metal 1 is embedded. After the concrete 6 is hardened, the installation position of the embedded hardware 1 is searched, and the concrete 6 is cut out to expose the mounting surface of the embedded hardware 1. Next, a support fitting or the like (not shown) is fixed to the exposed surface, and a pipe or the like is attached.

As shown in FIG. 6 (3), since the reinforcing bar 5 exists in the concrete layer, the stud gibber 4 of the embedded metal 1 comes into contact with the reinforcing bar 5. Since the installation location of piping, electric wires, etc. is designated in the building, the installation location of the embedded hardware 1 that supports this cannot be changed.
Therefore, in order to avoid contact with the reinforcing bar 5 in the concrete layer and the stud dowel 4, the stud dowel 4 is bent to the extent that it does not come into contact with the reinforcing bar.

    However, when installing a plurality of embedded metal objects in the concrete layer, there are a large number of studs that are in contact with the reinforcing bars, and the studs are provided with a certain level of strength, so that the bending is not an easy task. Therefore, there has been a problem that a great amount of time and labor are required for the construction of the embedded metal fitting.

  The present invention, in the operation of embedding an embedded metal used to support piping etc. on the ceiling surface, wall surface, etc. of a concrete building in the concrete layer, when the reinforcing bar in the concrete layer and the stud gibber are in contact with each other, It is an object of the present invention to provide a post-placement type embedded metal fitting that can embed an embedded metal so as not to come into contact with a reinforcing bar in concrete without changing the construction site of the embedded metal.

  According to the gibber post-insertion embedding according to the present invention, a plate embedded in a concrete layer of a concrete building, a gibber attached to the plate, and a plurality of mounting holes perforated more than a prescribed number of gibbers installed in the plate Is formed.

A plate embedded in the concrete layer of the concrete building; a diver attached to the plate; an attachment hole formed by drilling the plate to form a taper; and a taper fitted to the attachment hole to form the taper. In the post-installation type embedded metal fixture composed of a plug to be a stop, the mounting holes are formed in a larger number than the prescribed number of installation sites in the plate.
In this case, the unnecessary attachment holes may be provided with closing means.

  According to the gibber-type embedded metal fitting of the present invention, a plate embedded in a concrete layer of a concrete building, a gibber attached to the plate, and a plurality of mounting holes perforated more than a prescribed number of gibbers installed in the plate. Forming.

    Therefore, when the plate and the stud dowel are separated from each other, and the obstacle such as a reinforcing bar in the concrete and the stud dowel of the embedded metal are in contact with each other, the stud dowel is attached to the attachment hole at a position where it does not contact the obstacle. Contact can be easily avoided. Thereby, it becomes possible to construct the embedded metal in the designated place without changing the designated place for embedding the embedded metal.

    A plate embedded in the concrete layer of the concrete building; a gibber attached to the plate; an attachment hole formed by drilling the plate to form a taper; and a taper fitted to the attachment hole to form the taper. In the post-installation type embedded metal fixture composed of a plug to be a stop, the mounting holes are formed in a larger number than the prescribed number of installation sites in the plate.

    This makes it possible to easily correct the deviation of the setting position of the bending bevel head caused by the tightening of the gibel by adjusting the tightening of the plug when the stud is mounted on the plate using the bent bend stud instead of the straight stud. . Thereby, it becomes possible to construct the embedded metal in the designated place without changing the designated place for embedding the embedded metal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a gibber post-insertion embedded metal according to the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited only to the following embodiment.
FIG. 1 is an explanatory view of a post-installation embedded metal fitting according to this embodiment. As shown in FIG. 1, the gibber post-insertion embedded metal 10 according to the present invention is composed of a rectangular plate 12 and a stud gibber 14.

    The number of dowels installed on the embedded metal plate varies depending on the thickness, shape, etc. of the plate, and the number of attachments is defined. In the present embodiment, a case will be described in which the prescribed number of stud gibbles installed on the plate 12 is used.

    The plate 12 has mounting holes 16a, 16b, 16c, and 16d that serve as reference holes for inserting the stud dowels 14 at four corners. The inner peripheral surface of the mounting hole 16 is formed with a female screw portion so that a male screw portion 14a of a stud gibber 14 described later is screwed. Further, the plate 12 has four mounting holes 16e, 16f, 16g, and 16h, which are larger than the prescribed number of dowels, at positions that are intermediate points between the mounting holes 16a, 16b, 16c, and 16d at the four corners.

  As shown in FIG. 1 (2), the stud dowel 14 is formed with a male screw portion 14 a having a length corresponding to the thickness of the plate 12 or less at the tip. The male screw portion 14 a is screwed with the female screw portion of the mounting hole 16 of the plate 12. Further, the other end portion of the stud diver 14 is formed with a head portion 14b having a diameter larger than the diver diameter. A cylindrical portion 14c from the head portion 14b of the stud gibel 14 to the male screw portion 14a is formed with an embedding dimension c. In addition, the embedding dimension c and the diameter of the cylindrical portion 14c are arbitrarily set depending on the suspension load.

  The construction example of the gibber post-insertion embedded metal 10 having the above configuration will be described. FIG. 2 is a plan view from the inside of the concrete layer at the plate construction site. When installing the post-placement type embedded metal fitting 10 in the concrete layer, first, the plate 12 is arranged at a construction location. As shown in FIG. 2 (1), when the reinforcing bars 18 existing in the concrete layer do not contact the mounting holes 16a, 16b, 16c, 16d of the plate 12, the mounting holes 16a, 16b, The male screw portion 14a of the stud gibber 14 is screwed into the female screw portions 16c and 16d. Next, the post-placement embedded metal fitting 10 is fixed to the reinforcing bars 18 by temporary fixing, and concrete is placed.

    On the other hand, as shown in FIG. 2 (2), a reinforcing bar 18 may exist on the mounting holes 16a, 16b, 16c, and 16d of the plate 12 depending on the construction location of the post-insert type embedded metal fitting 10. At this time, when the stud dowel 14 is screwed to the plate 12 at the mounting hole 16a of the plate 12, the reinforcing bar 18 and the stud dowel 14 come into contact with each other. Therefore, the stud dowel 14 is screwed into a position where contact with the reinforcing bar 18 can be avoided, for example, the position of the mounting hole 16e.

  Next, a second embodiment of the gibber last-placed embedded metal according to the present invention will be described with reference to FIG. The gibber shown in FIG. 3 uses a taper as a fixing means for fixing to the plate 12. That is, the dowel post-insertion type embedded metal of the second embodiment is composed of the stopper plug 20, the taper plug 22, and the stud gibel 24. Further, as shown in FIG. 3B, the tapered mounting hole 26 of the plate 12 is formed with a taper whose diameter is reduced from the surface of the concrete in which the plate 12 is embedded toward the inside.

    The head 20a of the stopper plug 20 has the same diameter as that of the tapered mounting hole 26 of the plate 12, and a cross hole 20b is formed on the side surface. Further, the male threaded portion 20c of the stopper plug 20 is formed so as to be screwed with a female threaded portion 24a of a stud gibel 24 described later.

    As shown in FIG. 3B, the tapered plug 22 has a taper formed on the outer periphery thereof so as to be fitted into the taper in the tapered mounting hole 26 of the plate 12. Further, the female threaded portion 22a of the taper type plug 22 is formed so as to be screwed with a male threaded portion 24b of a stud dowel 24 described later. Further, a cross hole 22b is formed on the side surface of the tapered plug 22 on the large diameter side.

    The stud dowel 24 is formed with a male screw portion 24b that is screwed with the female screw portion 22a of the tapered plug 22 at the end. In addition, an internal thread portion 24 a that is screwed into the external thread portion 20 c of the stopper plug type plug 20 is formed inside the external thread portion 24 b of the stud diver 24. As shown in FIG. 3 (3), a flange portion 24 c having a diameter larger than the opening diameter of the tapered mounting hole 26 of the plate 12 is formed on the surface where the stud gibber 24 and the plate 12 contact. There are two types of stud gibber 24, one having a cylindrical portion formed straight, and one having a cylindrical portion 24d having a curve as shown in FIG. The cylindrical portion 24d is formed to have the same length as the embedded dimension c of the stud gibber 14. Further, a head 24e is formed at the other end of the stud divel 24 so as to have a larger diameter than the diver diameter.

    When the dowel is fixed to the plate 12, it can be fixed by using only the tapered plug 22 as shown in FIG. However, since the plate 12 has a plurality of thicknesses, the thickness of the plate 12 may be larger than the thickness of the tapered plug 22 as shown in FIG. In this case, by using the stopper plug 20, the concave portion generated between the tapered mounting hole 26 and the taper plug 22 is filled and the position of the plate 12 is adjusted.

    With the above configuration, an example of construction of the embedded metal using the stud gibber 24 will be described. FIG. 4 (1) is a plan view from the inside of the concrete layer at the place where the plate is constructed. FIG. 4B is a cross-sectional view taken along the line AA in FIG. As shown in FIG. 4, a straight stud dowel 24f is used on the tapered attachment holes 26b, 26c, and 26d where the tapered attachment holes 26 of the plate 12 do not contact the reinforcing bars 18. On the other hand, in the tapered attachment hole 26a having the reinforcing bar 18 on the opening, the bent stud gibel 24 is used to avoid contact with the reinforcing bar 18. That is, the bent stud dowel 24 is installed at a location where it does not come into contact with the reinforcing bar 18, and the bent stud dowel 24 is fixed to the plate 12 by screwing the tapered plug 22 from the opposite side of the mounting hole. At this time, as shown in FIG. 4 (2), the tapered mounting hole 26 and the taper type plug 22 are slidable, so that the stud dowel 24 bent by tightening may be displaced and come into contact with the reinforcing bar 18. Can also be easily modified to avoid contact with the rebar 18. Further, after the taper type plug 22 is attached to the plate, when a concave portion is formed between the tapered plug 22 and the plate 12, the stopper plug 20 is screwed into the stud gibel 24 to correct the concave portion of the plate 12 so that the position of the claws is corrected. Match.

    Furthermore, as shown in FIG. 5, the tapered attachment hole 26 that does not use the stud gibel 24 may be closed by retrofitting. That is, the outer lid 30 is formed so that a female screw portion is formed inside and fitted into the tapered mounting hole 26. Further, the inner lid 32 has a male screw portion that is screwed into the female screw portion of the outer lid 30, and the head portion 32 a is formed larger than the opening of the tapered attachment hole 26.

    With this configuration, out of the plurality of mounting holes perforated more than the prescribed number of gibbers to be installed in the plate, the outer lid 30 is connected to the taper mounting hole 26 of the plate 12 from the concrete surface side with respect to the mounting hole to which the diver is not attached. Next, the male screw portion of the inner lid 32 can be screwed into the female screw portion of the outer lid 30 and closed from the inside of the concrete layer.
