Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combined structure of an anchor for mounting / fixing a panel for a building wall material to a structure and an embedded positioning jig for positioning the anchor. is there.

[0002]

2. Description of the Related Art Conventionally, as this type of combined structure, for example, ones shown in FIGS. 7 to 9 are known. In each drawing, 51 is an anchor made of a metal pipe, and 55 is an embedding position adjusting jig in which an operating portion 56 that is manually operated is provided at one end. At the other end of the embedding position adjusting jig 55, a rubber tube 60 is fitted and fixed by a nut 58.

In this combined structure, when the rubber tube 60 of the embedding position adjusting jig 55 is press-fitted into the pipe hole 53 of the anchor 51, the anchor 51 and the embedding position adjusting jig 55 are integrally connected. Therefore, by holding the operation portion 56 by hand, the anchor 51 is inserted into the anchor embedding hole previously drilled in the panel (not shown), and at the position of the bolt insertion hole that connects the anchor embedding hole and the panel surface side, Align the bolt holes 52 of the anchor 51. After that, the bolt passed through the bolt insertion hole is screwed into the bolt hole 52 to fix the anchor 51. Thus, the panel is attached / fixed to the structure via the anchor 51 and bolts. After that, the embedded positioning jig 55 is pulled out from the pipe hole 53 of the anchor 51.

[0004]

However, the conventional anchor 51 and the embedding position adjusting jig 55 have the rubber tube 60.
Since they are connected using the rubber elasticity of No. 3, it is difficult to attach the rubber tube 60 of the embedding position adjusting jig 55 to the pipe hole 53 of the anchor 51. Further, since the engagement state between the anchor 51 and the embedding position adjusting jig 55 is elastic and the fixing force is unstable, for example, due to the pressing force when screwing the panel fixing bolt into the bolt hole 52,
The anchor 51 may move, and the screwing operation is not easy.

Further, the rubber tube 60 deteriorates early and is easily damaged by repeated fitting and positioning operations. Therefore, when the anchor 51 is in strong contact with the inner surface of the anchor embedding hole, no matter how many times the operation portion 56 is rotated, the rubber cylinder 60 causes the inner peripheral surface of the anchor 51 or the embedding positioning jig 55. There was a case in which the anchor 51 could not be aligned at a predetermined position by spinning around the outer peripheral surface of the. Further, the deteriorated rubber tube 60 may fall off from the tip of the embedding positioning jig 55 when the jig is pulled out, and it is necessary to replace the rubber tube 60 relatively early in order to prevent these problems. there were.

As described above, if the rubber cylinder 60 idles and the alignment is not easy or comes off, the mounting work is interrupted each time, or the embedded alignment jig 55 is additionally prepared. In a construction site with many attachment points, the loss of labor and working time has become a serious problem.

The present invention has been made in view of the above-mentioned conventional problems, and by firmly connecting the anchor and the embedding position adjusting jig, the anchor is fixed at a predetermined position in the anchor embedding hole. It is an object of the present invention to provide a combined structure of an anchor and an embedding position adjusting jig capable of extremely easily and quickly performing position adjustment.

[0008]

In order to achieve the above object, a combination structure of an anchor and an embedding position adjusting jig according to the present invention has an anchor embedding hole provided in the panel substantially along the surface of the panel. -Shaped anchor to be inserted into the anchor, and an embedding position adjusting jig for aligning the anchor at a predetermined position in the anchor embedding hole by having the operation part at one end and the other end being detachably connected to the anchor And a male screw portion is formed on one of the other end of the embedding position adjusting jig and the rod end portion of the anchor, and a female screw portion is formed on the other, and these male screw portion and female screw portion are formed. It is configured to connect the embedding position adjusting jig and the anchor by screw fitting.

In the present invention having the above structure, first, the anchor and the embedding position adjusting jig are integrally connected by screw fitting. Then, the operating portion of the embedding positioning jig is held, and the anchor is inserted into the anchor embedding hole of the panel. Further, the anchor is aligned in position within the anchor embedding hole. At this time, since the anchor and the embedding positioning jig are integrally and firmly connected to each other, the positioning can be easily performed. Subsequently, the anchor is fixed in the panel with, for example, a bolt. Thereafter, the embedding position adjusting jig is turned in the opposite direction to release the screw fitting state, so that the embedding position adjusting jig is removed from the anchor.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below. 1 is a perspective view showing an anchor and an embedding position adjusting jig according to the present invention, FIG. 2 is a front view showing the anchor, and FIG. 3 is a front view showing the embedding position adjusting jig.
In these figures, 1 is an anchor composed of a round bar made of carbon steel for cold rolling, in which a bolt hole 2 is threaded at the center and screw holes 3 are formed at both ends. There is. Female screw portions 4 are formed on the inner peripheral surface of each screw hole 3.

Reference numeral 5 denotes an embedding position adjusting jig having a T-shaped operation portion 6 for operation by hand, which is formed at one end. The embedding position adjusting jig 5 is made of a tubular material, and a female screw (not shown) is formed at the opening on the other end side. A male screw tube 7 (an example of a male screw portion) is screwed into the female screw of the opening on the other end side. The male screw tube 7 is formed so that it can be screwed into the female screw portion 4 of the anchor 1. Further, a nut 8 for adjusting the tip length of the male screw portion is attached to the male screw tube 7, and the male screw tube 7 is fixed by the surface contact with the end surface of the embedding positioning jig 5. However, the male screw portion of the present invention does not necessarily have to be a separate member from the embedding position adjusting jig 5 like the male screw tube 7 described above, and for example, the outer peripheral surface of the other end portion of the embedding position adjusting jig 5 can be used. It may be a male screw formed directly on the.

As shown in FIG. 4, the anchor 1 and the embedding position adjusting jig 5 hold the operating portion 6 by hand and connect the male screw pipe 7 of the embedding position adjusting jig 5 to the female screw portion 4 of the anchor 1.
The end face of the anchor 1 and the end face of the nut 8 of the embedding position adjusting jig 5 come into surface contact with each other and are simply and firmly connected by simply screwing into.

Then, as shown in FIG. 5, the anchor 1
Is used for attaching / fixing a panel 13 made of lightweight cellular concrete (abbreviation: ALC) to a structure 10 made of H-section steel or the like. An anchor embedding hole 14 parallel to the panel surface is provided in the panel 13. Further, a bolt insertion hole 15 that communicates with the anchor embedding hole 14 is provided on the front surface side of the panel 13. In the figure, 11 is an L-shaped angle welded on the structure 10, and 12 is a stepped mounting bracket.

Therefore, the anchor 1 integrated with the embedding position adjusting jig 5 is inserted into the anchor embedding hole 14 of the panel 13 by the operator's hand. At this time, since the anchor 1 is firmly connected to the embedding positioning jig 5, the operating portion 6
Even if the anchor 1 is in strong contact with the inner surface of the anchor embedding hole 14, the anchor 1 is idle with respect to the embedding position adjusting jig 5 in order to rotate in one direction (the direction in which the screw is tightened). Without doing so, the bolt hole 2 of the anchor 1 can be moved in the axial direction or the circumferential direction of the anchor 1 to a position facing the bolt insertion hole 15 of the panel 13 for easy alignment.

Therefore, as shown in FIG.
Through the bolt insertion hole 15 with the bolt 16 inserted in
When this is further screwed into the bolt hole 2, the panel 13 has an L-shaped angle 11, a mounting bracket 12, a bolt 16, and an anchor 1.
It is fixed to the structure 10 via. This is anchor 1
Since rotation of the embedded positioning jig 5 is restricted, if the embedded positioning jig 5 is turned in the direction in which the screw loosens, the screwed state with the anchor 1 is released, the embedded positioning jig 5 is removed from the anchor 1, and It is used for the anchor alignment work of. In this way, the panel 13 can be attached and fixed to the structure 10 quickly and reliably.

That is, since the anchor 1 and the embedding position adjusting jig 5 are firmly connected by screw fitting,
The connected state does not change during operation. Further, since all of them are made of a rigid body, they are not easily deformed and are not easily damaged by repeated use. on the other hand,
Even when the embedding position adjusting jig 5 is removed, there is no risk that parts will fall off and remain in the anchor embedding hole 14.

In the above description, the embodiment is shown in which the female screw portion is provided on the anchor side and the male screw portion is provided on the jig side. On the contrary, the male screw portion is provided on the anchor side and the jig side is provided on the jig side. It may be provided with a female screw portion.

In the above description, the round bar constitutes the anchor, but the anchor is not limited to this and may be, for example, a pipe-shaped one. In that case, a female screw portion may be formed on the anchor side and a male screw portion may be formed on the jig side.

[0019]

As described above, in the combined structure of the anchor and the embedding position adjusting jig according to the present invention, the embedding position adjusting jig and the anchor are combined by the screw fitting of the male screw part and the female screw part. Since they are connected, the anchor can be extremely easily and quickly aligned with the predetermined position of the anchor embedding hole of the panel. In addition, for example, even when the bolt is fixed to the anchor, the anchor can be securely held at a predetermined position, so that the bolt can be screwed into the anchor very easily. Therefore, it is possible to reduce the time and labor required for the panel mounting work, and it is possible to greatly contribute to the efficiency of the panel mounting work.
