Anchor for drywall with improved holding pressure {Anchor for drywall}

The present invention vertically bends a pressure plate supported on the rear surface of a lightweight wall panel at both ends of a semi-cylindrical anchor bracket, thereby maintaining a strong fixing force without damaging the lightweight wall panel and reducing manufacturing cost due to a simple configuration. It is about an anchor for drywall with improved holding pressure.

In the existing reinforced concrete apartment house, the wall inside the household is constructed together with the outer wall and constructed by the wet method of pouring concrete inside the formwork, or by the masonry or ALC method.

However, the wet method increases the construction cost due to the high proportion of labor costs, and it is difficult to secure homogeneous quality. In addition, the masonry or ALC method is highly dependent on manpower, so the proportion of labor costs is high and it takes a lot of time. In addition, ALC block is weak against moisture, so it is difficult to use it in a space where water is used, such as a bathroom.

In recent years, cases of applying a dry method instead of a wet method, masonry or ALC method for wall construction within households are increasing.

For drywall, runners are installed on the upper part of the lower slab and the lower part of the upper slab, respectively, and studs are installed in a vertical direction between the upper and lower runners, and then lightweight wall panels are attached to the front and rear surfaces of the studs.

At this time, a bracket is installed on the front of the dry wall to fix shelves or furniture to the dry wall, and toggle anchors are often used to fix the bracket to the dry wall (Patent Nos. 10-0499680 and 10-0897721 arc, etc.).

In this way, the anchor bracket 60 is caught on the rear surface of the lightweight wall panel 1, and the protruding part of the strap 70 is cut by bending the protruding part of the strap 70 in a state where the flange 810 of the cap member 80 is caught on the front surface. Then, the cap member By screwing the fastening member 2 to the rear end of the anchor body 50 through 80, the bracket 3 for fixing the fixture is fixed to the front of the lightweight wall panel 1.

In such a conventional toggle anchor, the anchor bracket is formed in a semi-cylindrical shape, and thin portions at both ends in the width direction of the anchor bracket are adhered to and supported on the back surface of the lightweight wall panel. Therefore, when the pulling force of the strap is strong, the side end of the anchor bracket digs into the gypsum board of the lightweight wall panel, and there is a problem in that the anchor is not firmly fixed.

In addition, in the conventional toggle anchor, since the anchor body and the anchor bracket are separated and hinged, the number of members and the configuration are complicated, resulting in an increase in manufacturing cost.

As shown in FIGS. 3 and 4, the anchor for drywall with improved holding pressure of the present invention is a lightweight wall panel (1) for fixing and installing a fastening member (2) for fixing a mechanism to a lightweight wall panel (1) of drywall. It relates to a dry wall anchor (4) installed through the anchor hole (11) of the anchor bracket (5), which is formed in a semi-cylindrical shape and is provided with a support plate (521) that is vertically bent outward at both ends in the width direction, respectively. ); The front end is coupled to the anchor bracket (5), the rear end is a cable tie (6) protruding to the front of the lightweight wall panel (1) through the anchor hole (11) of the lightweight wall panel (1); and a fixing sleeve 7 slidably coupled to the cable tie 6 and having a through hole 71 formed in the center thereof; It is characterized by consisting of.

An object of the present invention is to provide a drywall anchor (4) that can maintain a solid fixing force without damaging the lightweight wall panel (1) and can reduce manufacturing cost with a simple configuration, thereby improving economical holding pressure.

The drywall anchor 4 of the present invention is for fixing fixtures such as shelves or furniture to the drywall.

The mechanism can be fixed to the dry wall by means of a bracket (3) fixed to an anchor (4) by means of a fastening member (2). The fastening member 2 may be a bolt, screw, or the like.

An anchor hole 11 is formed through the lightweight wall panel 1 in order to install the dry wall anchor 4 to the lightweight wall panel 1.

The dry wall anchor (4) is composed of an anchor bracket (5), a cable tie (6) and a fixing sleeve (7).

Based on the direction in which the drywall anchor 4 is installed on the lightweight wall panel 1, the 'front end' refers to the anchor bracket 5 side and the 'rear end' refers to the fixing sleeve 7 side. .

The anchor bracket 5 is formed in a semi-cylindrical shape, and is provided with pressure plates 521 vertically bent outward at both ends in the width direction, respectively (FIGS. 4 and 5).

The anchor bracket 5 is formed in a semi-circular cross section, that is, a semi-cylindrical shape in order to minimize the diameter of the anchor hole 11 of the lightweight wall panel 1 formed in a circular shape.

A fastening hole 511 having a tapped inner circumferential surface may be formed at the center of the anchor bracket 5 so that the front end of the fastening member 2 is screwed.

The anchor bracket 5 may be made of metal or synthetic resin material.

The front end of the cable tie 6 is coupled to the anchor bracket 5, and the rear end protrudes to the front of the lightweight wall panel 1 through the anchor hole 11 of the lightweight wall panel 1.

In a state in which the front end of the cable tie 6 is coupled to the anchor bracket 5, the anchor bracket 5 can be laid horizontally to pass through the anchor hole 11 of the lightweight wall panel 1 (FIG. 9 ). Then, when the cable tie (6) is pulled from the front side of the lightweight wall panel (1), the anchor bracket (5) and the cable tie (6) erected in the vertical direction form a T-shape, and the anchor bracket (5) is attached to the lightweight wall. It is closely supported on the rear surface of the panel 1 (FIG. 10).

At this time, when the anchor bracket 5 is simply formed in a semi-cylindrical shape, thin portions of both ends in the width direction of the anchor bracket 5 are supported by the lightweight wall panel 1. Therefore, by vertically bending both ends of the anchor bracket 5 in the width direction outward to form a pressure plate 521, the anchor bracket 5 is supported on the rear surface of the lightweight wall panel 1 by surface contact of the pressure plate 521. can make it

Here, both ends of the anchor bracket 5 in the width direction mean ends of both side walls parallel to each other in a semi-cylinder (FIG. 5).

Accordingly, even if the cable tie 6 is pulled with strong force, the anchor bracket 5 is stably supported without digging into the rear surface of the lightweight wall panel 1.

In addition, since the fastening member 2 and the cable tie 6 are directly coupled to the anchor bracket 5 without a separate anchor body, the configuration is simple, reducing the number of members and increasing production efficiency, which is economical.

The cable tie 6 may be formed of synthetic resin.

Since the cable tie 6 has good flexibility, it is easy to lay the anchor bracket 5 in a horizontal direction and maintain it in a straight line with the cable tie 6 even if it is not hinged to the anchor bracket 5.

The fixing sleeve 7 is slidably coupled to the cable tie 6 and has a through hole 71 formed in the center.

On the rear side of the cable tie (6), a fixing sleeve (7) for temporarily fixing the anchor bracket (5) so that it does not fall to the rear side of the lightweight wall panel (1) and maintains a state closely supported on the rear surface of the lightweight wall panel (1). ) are combined.

The cable tie 6 interconnects the front anchor bracket 5 and the rear fixing sleeve 7. At the front end of the cable tie (6), the anchor bracket (5) is caught on the back of the lightweight wall panel (1), and at the rear end, the fixing sleeve (7) is caught on the front of the lightweight wall panel (1) and the anchor (4) goes. it is decided

A through hole 71 is formed in the center of the fixing sleeve 7 so that the fastening member 2 can pass therethrough. In addition, a tie through hole 72 through which the cable tie 6 passes is formed in the fixing sleeve 7 (Fig. 7(a) and (b)).

The fixing sleeve 7 is guided by the cable tie 6 so that it can slide only to the front side, and the movement to the rear side is restricted so that the fixing sleeve 7 can be kept in close contact with the lightweight wall panel 1. should be able to Accordingly, a toothed portion 61 inclined toward the front side is formed on one surface of the cable tie 6 (FIG. 6), and the toothed portion 61 is formed on the inner surface of the tie through hole 72 of the fixing sleeve 7. A hanging hook 73 may be formed (Fig. 7 (a)).

5 is a plan view showing an anchor bracket.

As shown in FIGS. 4 and 5, the anchor bracket 5 is formed in a semi-cylindrical shape, and the anchor body 51 to which the cable tie 6 and the fastening member 2 are coupled, and the anchor body 51 It is provided at both ends in the longitudinal direction of the semi-cylindrical shape having a smaller outer diameter than the anchor body 51, and may be composed of support parts 52 formed so that the pressure plate 521 is vertically bent outward at both ends in the width direction.

When the pressure plate 521 is vertically bent to both sides of the anchor bracket 5, the overall width of the anchor bracket 5 is increased due to the protrusion of the pressure plate 521. In this case, in order for the anchor bracket 5 to pass through the anchor hole 11, the diameter of the anchor hole 11 drilled in the lightweight wall panel 1 must be increased, so the workability is poor.

In this way, in order to prevent the overall width of the anchor bracket 5 from increasing due to the pressure plate 521, a method of narrowing the gap between both sides of the wall of the semi-cylindrical anchor bracket 5 may be considered. However, in this case, since the inlet is narrow, it is difficult to directly fasten the fastening member 2 to the anchor bracket 5, and the size of the diameter of the fastening member 2 is limited.

Therefore, while easily fastening the fastening member 2, the anchor body 51 to which the fastening member 2 is coupled is disposed in the center of the anchor bracket 5 so that the drilling diameter of the anchor hole 11 does not need to be enlarged, , The support portion 52 provided with the pressure plate 521 may be disposed at both ends of the anchor body 51 in the longitudinal direction.

The support part 52 may extend from both ends of the anchor body 51 in the longitudinal direction and be integrally formed.

The support portion 52 may have an outer diameter smaller than that of the anchor body 51 and may be provided with pressure plates 521 vertically bent outward at both ends in the width direction, that is, both side wall ends.

The support part 52 is supported on the rear surface of the lightweight wall panel 1 from the outside of the anchor hole 11.

The width (w) of the support portion 52 including the pressure plate 521 may be formed to be the same as that of the anchor body 51 (FIG. 5).

Accordingly, even though the pressure plate 521 is provided, since the overall width of the anchor bracket 5 does not increase, construction can be performed without increasing the perforation diameter of the anchor hole 11.

Since the cable tie 6 must be drawn out to the front of the lightweight wall panel 1 through the anchor hole 11, the front end is coupled to the anchor body 51 side of the anchor bracket 5.

As shown in FIG. 4 and the like, fixing tips 513 inserted into the rear surface of the lightweight wall panel 1 may protrude from both ends of the anchor body 51 in the width direction.

Fixing tips ( 513) may be protruded.

The fixing tips 513 may be configured such that a pair of fixing tips 513 are provided to be spaced apart from each other at the top and bottom to be inserted into the rear surface of the lightweight wall panel 1 from the outside of the anchor hole 11 .

Accordingly, the pressure plate 521 may support the pulling force by the cable tie 6, and the fixing tip 513 may support vertical sliding.

It is preferable that the end of the fixing tip 513 on the side of the lightweight wall panel 1 is pointed so as to be easily inserted into the side of the lightweight wall panel 1.

6 is a perspective view showing a cable tie.

As shown in FIGS. 5 and 6, a hooking hole 512 is formed through the anchor bracket 5, and a hooking part inserted into the hooking hole 512 at the front end of the cable tie 6 ( 62) may be provided.

In order to directly fix the cable tie 6 to the anchor bracket 5 without a separate coupling member, a hooking hole 512 is formed in the anchor bracket 5, and the front end of the cable tie 6 is hooked to the hooking hole 512. ) can be inserted and combined.

Engaging portions 62 extending to both sides may be provided at the front end of the cable tie 6 so that the cable tie 6 does not fall out when the front end of the cable tie 6 is inserted into the locking hole 512 .

In addition, when passing the anchor bracket (5) through the anchor hole (11), the cable tie (6) must be pushed in from the front of the lightweight wall panel (1). At this time, the pressing force of the cable tie (6) is applied to the anchor bracket (5). ) A support piece 63 for supporting the inside of the anchor bracket 5 may be formed at a position spaced apart from the rear of the hooking part 62 by a predetermined interval so as to be delivered to.

7 is a perspective view showing an embodiment of a fixing sleeve.

As shown in FIGS. 3 and 7 , the outer circumferential surface of the fixing sleeve 7 may be provided with a wing portion 74 protruding and bendable.

7 (a) and (b) are perspective views showing the front and rear surfaces of the fixing sleeve 7, respectively.

Since the diameter of the anchor hole 11 drilled on site is not constant, a gap between the fixing sleeve 7 and the inner diameter of the anchor hole 11 is inevitable, so the fixing sleeve (cap member) is fixed without falling into the anchor hole 11. In order to do so, it is necessary to form a flange protruding from the outside of the cap member so that it is supported on the front surface of the lightweight wall panel (FIG. 2).

In this case, there is a problem in that the bracket does not come into close contact with the front surface of the lightweight wall panel due to the interference of the flange, so that the bracket flows during use.

Therefore, even if there is a gap between the outer diameter of the fixing sleeve 7 and the inner diameter of the anchor hole 11, the outer circumferential surface of the fixing sleeve 7 can be bent so that the fixing sleeve 7 can be firmly fixed in the anchor hole 11. A protruding wing portion 74 may be provided.

When the operator pushes the fixing sleeve 7 into the anchor hole 11 while pulling the cable tie 6, the wing part 74 moves to the rear side, that is, the lightweight wall panel, by the pressure of the lightweight wall panel 1. While being bent toward the front side of (1), it is inserted into the anchor hole 11 together with the fixing sleeve 7 (FIG. 12).

Accordingly, the bent wing portion 74 fills the gap between the fixing sleeve 7 and the anchor hole 11 so that the fixing sleeve 7 is firmly fixed in the anchor hole 11 .

The wing part 74 is formed on the central part or front side of the fixed sleeve 7 instead of the rear side of the fixed sleeve 7 so that the bent wing part 74 does not protrude to the front of the lightweight wall panel 1. desirable. In this case, the wing portion 74 does not protrude to the rear of the fixed sleeve 7 in a bent state.

A plurality of the wing parts 74 may protrude radially from the outer circumferential surface of the fixing sleeve 7 .

8 is a perspective view showing another embodiment of a fixing sleeve.

As shown in FIG. 7 and the like, a fitting protrusion 75 may protrude from the outer circumferential surface of the fixing sleeve 7 in the longitudinal direction of the fixing sleeve 7 .

The front end of the fixing sleeve 7 is forcibly fitted into the anchor hole 11 before the fastening member 2 is fixed.

Thereafter, when the fastening member 2 is fastened, the wing 74 of the fixed sleeve 7 is bent and the wing 74 must be accommodated in the anchor hole 11. When the wing 74 is bent, the wing 74 is bent. Since the outer diameter increases by the thickness of the portion 74, it may be difficult to insert the wing portion 74 into the anchor hole 11.

Therefore, the outer diameter of the fixing sleeve 7 is formed smaller than the inner diameter of the anchor hole 11 in consideration of the thickness of the wing part 74, but the overall outer diameter corresponds to the inner diameter of the anchor hole 11 when the wing part 74 is bent. can be configured to Instead, fitting protrusions 75 may be formed on the outer circumferential surface of the fixing sleeve 7 so that the fixing sleeve 7 is forcibly fitted into the anchor hole 11 until the wing portion 74 is bent.

In the embodiment of FIG. 7 , it is shown that the fitting protrusion 75 protrudes over the entire longitudinal direction of the fixing sleeve 7 between adjacent wing parts 74 .

It is enough for the fitting protrusion 75 to protrude only on the front side of the fixing sleeve 7 .

In addition, the fitting protrusion 75 can be formed long in the longitudinal direction of the fixing sleeve 7 so that it can be easily inserted into the anchor hole 11, but in some cases it is also possible to form a ring shape as shown in FIG. .

The fitting protrusion 75 may have the same thickness as the thickness of the bent wing 74 .

When the fixing sleeve 7 is inserted into the anchor hole 11, the front end of the fitting protrusion 75 may be formed to be tapered so as to facilitate entry.

The present invention is for fixing fixtures such as shelves or furniture to a dry wall, and can be constructed in the following order.

First, an anchor hole 11 is drilled in the lightweight wall panel 1.

Then, in a state where the cable tie 6 and the anchor bracket 5 combined in a T shape are laid in a horizontal direction to be in line with the cable tie 6, the anchor 4 is passed through the anchor hole 11 (FIG. 9 ).

When the anchor bracket 5 passes through the anchor hole 11, the anchor bracket 5 rotates in the vertical direction again by the elasticity of the cable tie 6, so that the anchor bracket 5 and the cable tie 6 are connected to the T will achieve self-form Pull the cable tie 6 to attach the anchor bracket 5 to the rear surface of the lightweight wall panel 1 (FIG. 10).

Next, the fixing sleeve 7 coupled to the cable tie 6 is advanced, inserted into the anchor hole 11 and fixed (FIG. 11), and then the fixing sleeve 7 is further advanced to fix the fixing sleeve 7. Completely accommodated into the anchor hole 11 (FIG. 12). At this time, the wing portion 74 of the fixing sleeve 7 is bent and pushed into the anchor hole 11 so that the fixing sleeve 7 is firmly fixed in the anchor hole 11 .

Thereafter, the portion of the cable tie 6 protruding outward from the fixing sleeve 7 is cut (FIG. 13).

Finally, the bracket (3) is placed in front of the anchor (4) of the lightweight wall panel (1), and the fastening member (2) passes through the fixing sleeve (7) to the fastening hole (511) of the anchor bracket (5). The bracket 3 is fixed by fastening (FIG. 14).
