Description

[Detailed explanation of the invention] This invention is based on a concrete product hanging support, and an anchor is buried in the end of a concrete product such as a building exterior wall panel, and the through hole of the anchor is recessed in the surface of the concrete product. Make it appear outside,
This is used when a hanging jig is engaged with this through hole to form a suspension support for the product.

As shown in FIG. 6, since the through hole 5 of the conventional anchor 10 was bored regardless of the cross-sectional shape of the engaging part 4 of the hanging jig 3, the product 41 was placed face down using the wire 11 and the hanging jig 3. When the product 41 was lifted in the direction of the arrow from the suspended state (FIG. 6), the lifting jig 3 rotated around the through hole 5 and hit the concave periphery 42 of the product 41, often causing damage to the concrete in the vicinity.

The present invention relates to a concrete product hanging support, and includes a plate portion having a through hole, an anchor having a foot portion protruding sideways at one end of the plate portion, and a hanging jig to be engaged with the through hole. and the cross section of the through hole and the engagement portion of the hanging jig prevents relative displacement of the hanging jig with respect to the anchor in a direction other than the engagement direction when the hanging jig is engaged with the through hole. The embodiment thereof will be described in detail with reference to the drawings as follows. In addition, in the drawing,
The same reference numerals indicate the same or corresponding parts.

The concrete product hanging support consists of an anchor and a hanging jig. The anchor 10 consists of a plate part 1 and a leg part 2 projecting laterally at one end of the plate part 1. This plate portion 1 has a non-circular through hole 5.
is worn. 3 is a lifting jig, and the cross-sectional shape of the engaging portion 4 that fits into the through hole 5 when lifting the concrete product 41 is non-circular. Through hole 5
is required to have a shape that prevents relative displacement of the hanging jig 3 with respect to the anchor 10 in a direction other than the engagement direction when the hanging jig 3 is engaged therewith. For example, in the examples shown in FIGS. 1 and 7, the cross section of the engaging portion 4 is rectangular, and the through hole 5 is formed by attaching semicircles on opposite sides of a pair of rectangles that are approximately the same size as this rectangle. It is becoming.

If the plate part 1 and the foot part 2 are manufactured as shown in FIGS. 2 and 3, the number of steps will be reduced, so that the anchor can be provided at a low cost. That is, an I- or H-shaped steel material 22 with flanges 21 at both ends is cut into a predetermined size by a holding mold 24 having a through hole 23 that fits the holding mold 24 and a cutting mold 25 that is movable along this. Fragment 26 is prepared. And the web 2
7 is divided into two to form plate parts 1, 1, and the part of the collar 1 becomes the foot part 2. This foot portion 2 may be further processed by pressing. When such steel is utilized, two anchors can be made from one piece 26 of steel.

Further, if the plate portion 1 and the foot portion 2 are manufactured as shown in FIGS. 4 and 5, the anchor can be manufactured at extremely low cost. In this case, it is suitable for lightweight use. That is, the plate part 1 prepares the fragment 2 for the anchor by cutting the flat steel material 31 into predetermined dimensions. Then, one end of this fragment 32 is held by a horizontal holding mechanism 33.
and a press device 35 having a vertical pressing mechanism 34. The parallel surface portion held by the lateral holding mechanism 33 is the plate portion 1, and the portion bulged in the lateral direction by this compression becomes the foot portion 2.

As shown in FIGS. 1 and 7, the anchor 10 is buried in a concrete product 41, and the surface layer of the concrete product 41 is peeled off at the hole 5 to expose the hole 5 to the outside. When lifting the product 41, the lifting jig 3 is fitted into the through hole 5. Although the hanging jig 3 can freely move in the engagement direction, movement in a direction that makes an angle with the engagement direction, such as tilting, is suppressed. In this state, if the wire 11 is pulled in the direction of the arrow in FIG. 7 to lift the lifting jig 3, the product 41
Since the hanging jig 3 does not collide with the peripheral edge 42 of the concave portion (see FIG. 7), the product will not be damaged.

According to the present invention, it is possible to prevent the concrete product from being damaged when the product is suspended.
