Abstract

The present invention is formed by bending the locking piece inward to the expansion portion of the lower end of the anchor embedded in the ceiling or wall, and when the anchor is pushed so that the expansion portion is opened by the inner wedge to open the locking piece together, By fixing the bottom of the anchor and at the same time the engaging piece is extended to the outside anchors the double function to be caught in the ceiling or inside the wall to prevent the anchoring and shaking.

To this end, in the present invention, when inserting the anchor anchored into the ceiling or the wall, the insert anchor is fixed, and divided into a plurality of slits in the lower portion of the anchor, and hit by the anchor to be punched by the wedge when driven into the hole It is provided with an extension that is inserted into the inner circumferential surface of the hole and fixed, and each of the expansion portion is provided with a bent portion bent into the interior of the anchor to open out the surface of the wedge while the expansion is opened to dig into the inner circumferential surface of the hole There is a fixed feature.

Description

Insert anchor}

The present invention relates to an insert anchor, and more particularly, to form an engaging portion of the lower end of the anchor embedded in the ceiling or wall bent inwardly and then the anchor is pushed into the anchor to open the expansion portion by the inner wedge By unfolding the one side together, the lower end of the anchor is fixed by the expansion portion and at the same time the engaging piece is extended to the outside anchored in the ceiling or the wall, and the anchor anchor has a dual function to prevent the falling off and shaking.

Insert anchors, also commonly called stud anchors, are used to secure an object such as a bracket, computer bolt, or handrail to a ceiling or wall.

4 and 5 are cross-sectional views of a conventional insert anchor, Figure 4 is a structure in which the anchor 1 is placed on top of the conical wedge 5, the anchor 1 is extended by a plurality of slits (2) at the bottom (3) is divided and a screw portion (4) for fastening the bolt is formed on the upper inner circumference. Therefore, when hitting the top of the anchor (1) strongly with a tool such as a hammer, the anchor (1) is pressed while its lower extension (3) is opened through the wedge (5) is fixed to the ceiling or wall embedded.

5 is a configuration in which the wedge 5a is inserted and stored inside the anchor 1a, which prevents the wedge 5a from falling into the cover 5b therein, and the slit 2a below the anchor 1a. An enlarged and inclined inclined portion 3b is provided inside the expanded portion 3a divided by. In such a state, when hitting the inner wedge 5a strongly, the expansion part 3a is opened by the wedge 5a and is fixed to the ceiling or the wall, and the cover 5b is made of a flexible material when the blow is made. It is a configuration that is torn inside the anchor 1a.

These conventional anchors (1) (1a) are equally fixed inside the ceiling or wall surface, and these extensions (3) (3a) of one end are opened. However, since the expansion part (3) (3a) is to be made in the state lying on the bottom of the anchor (1) (1a), only the bottom is fixed and the middle or upper part of the anchor (1) (1a) loosened in the hole drilled in the wall or ceiling There is a problem that shake does not occur because it is not placed.

In addition, when fixing an object such as a bracket or a handrail to the anchor (1) (1a) by using a computer bolt or a general bolt, the support force is all received from the expansion part (3) (3a), so a large support force is required. Where there was a disadvantage that can not be used for safety.

The present invention has been developed in view of the conventional problems, the object of the present invention is to form a bending piece inwardly to the extension of the lower end of the anchor embedded in the ceiling or wall surface, and then the anchor is pushed in the expansion by the internal wedges By inserting the engaging pieces to be unfolded together, the lower end of the anchor is fixed by the expansion portion and at the same time the engaging piece is extended to the outside while hanging on the ceiling or inside the wall to prevent the fall and shaking of the anchor inserts In providing an anchor.

To this end, in the present invention, when inserting the anchor anchored into the ceiling or the wall, the insert anchor is fixed, and divided into a plurality of slits in the lower portion of the anchor, and hit by the anchor to be punched by the wedge when driven into the hole It is provided with an extension that is inserted into the inner circumferential surface of the hole and fixed, and each of the expansion portion is provided with a bent portion bent into the interior of the anchor to open out the surface of the wedge while the expansion is opened to dig into the inner circumferential surface of the hole There is a fixed feature.

According to the present invention, since the engaging piece bent inwardly is formed in the extension part of the insert anchor fixed to the ceiling or the wall, the extension part is opened by the wedge and the bottom of the anchor is fixed to the ceiling or the wall.

At the same time, the locking piece bent inwardly in the extension part is pushed out by pushing the inclined outer circumferential surface of the wedge, and is extended outwardly to be caught in the hole of the ceiling or wall, so that the anchor is fixed at both the extension part and the locking piece. In addition, since the shaking of the anchor is prevented from the expansion part and the engaging piece, the workability is improved when fixing objects such as brackets and railings to the ceiling or the wall.

1 is a perspective view of the insert anchor of an embodiment of the present invention, Figure 2 is an installation state of the insert anchor in an embodiment of the present invention. In the present invention, a plurality of slits 11 are radially cut under the anchor 10, and a plurality of extensions 12 are formed by the slits 11. In addition, the upper inner circumference of the anchor 10 is formed with a threaded portion 13 for fastening the bolt and the general bolt, the expansion portion 12, the engaging piece 20 bent inward of the anchor 10 Is formed.

The locking piece 20 is configured to be elastically movable with respect to the lower end is composed of the upper and left, left, and right cut out portion 21 except the lower portion.

The insert anchor of an embodiment of the present invention configured as described above inserts the anchor 10 into the hole 40 formed in the ceiling or wall. At this time, the upper portion of the wedge 30 is weakly fitted to the lower portion of the anchor 10, the anchor 10 is protruded to the outside of the ceiling or wall surface. After hitting the upper exposed portion of the anchor 10 using a hammer-like tool, the anchor 10 is pushed into the hole 40 while being pushed into each of the expansion portions 12 by the wedge 30. The inner circumferential surface of the hole 40 is cut into and fixed.

In addition, while the anchor 10 enters, the engaging pieces 20 formed for each of the expansion parts 12 are opened to the outside by riding on the outer circumferential surface of the wedge 30 so as to dig into the inner circumferential surface of the hole 40 and are fixed. As a result, the anchor 10 is fixed to the inside of the hole 40 by the expansion part 12 and the locking piece 20 to prevent shaking and does not return.

The anchor 10 of the embodiment of the present invention is formed by a forging method or by bending the plate in a press to form the slit 11 and the engaging piece 20 in advance and then formed into a cylindrical anchor 10 by bending can do.
