In existing reinforced concrete apartment complexes, the walls within each unit are constructed together with the exterior wall using a wet method of pouring concrete inside the form, or they are constructed using a masonry or ALC method.

However, the wet method has a high labor cost, which increases construction costs, makes it difficult to secure uniform quality, and raises concerns about construction delays, especially in the winter. Additionally, the masonry or ALC method relies heavily on manpower, so labor costs are high and a lot of construction time is required. In addition, ALC blocks are vulnerable to moisture, making them difficult to use in spaces where water is used, such as bathrooms.

Accordingly, in recent years, there has been an increasing number of cases of applying dry methods instead of wet methods, masonry, or ALC methods to construct walls within households.

As shown in Figures 3 to 7, etc., the anchor bolt guide type drywall anchor of the present invention uses a lightweight wall panel (1) to fix and install the anchor bolt (2) for fixing the fixture to the lightweight wall panel (1) of the drywall. ) is installed through the anchor hole 11, and has a fastening hole 51 in the center into which the front end of the anchor bolt 2 is screwed (5); A strap (6) coupled to the anchor bracket (5) in a T shape; And it is slidably coupled to the strap 6, and an anchor bolt through hole 71 through which the anchor bolt 2 passes is formed in the center, and the shear is formed around the anchor bolt through hole 71. A fixing cap (7) on which a guide sleeve (73) coupled to the anchor bracket (5) protrudes toward the front side; It is characterized by being composed of.

The present invention provides a guide sleeve (73) at the front end of the fixing cap (7) to guide the entry of the anchor bolt (2) coupled to the anchor bracket (5) located on the back of the lightweight wall panel (1), thereby securing the anchor. The purpose is to provide an anchor bolt guide type drywall anchor that can easily fasten the bolt (2).

The drywall anchor 4 of the present invention is for fixing fixtures such as shelves, furniture, and home appliances to drywall or art walls.

The fixture can be fixed to the drywall by a bracket (3) that is fixed to the anchor (4) with an anchor bolt (2).

In order to install the drywall anchor 4 into the lightweight wall panel 1, an anchor hole 11 is formed through the lightweight wall panel 1.

The drywall anchor (4) consists of an anchor bracket (5), a strap (6), and a fixing cap (7).

Unless otherwise specified, 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 cap (7) side. Explain what it means.

The anchor bracket 5 is configured to be supported by hanging on the back of the lightweight wall panel 1, and a fastening hole 51 is formed in the center with the inner peripheral surface tapped so that the front end of the anchor bolt 2 is screwed (see Fig. 3).

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

The strap (6) is coupled to the anchor bracket (5) in a T shape.

The front end of the strap 6 is coupled to the anchor bracket 5, and the rear end protrudes toward the front of the lightweight wall panel 1 through the anchor hole 11 of the lightweight wall panel 1 (FIG. 7).

The strap (6) is approximately at right angles to the anchor bracket (5) and forms a T shape.

The fixing cap (7) is slidably coupled to the strap (6).

The fixing cap (7) is coupled to the rear side of the strap (6), so that the anchor bracket (5) supporting the rear side of the lightweight wall panel (1) is tightly adhered without falling to the rear side of the lightweight wall panel (1). Temporarily fix it to maintain the condition.

An anchor bolt through hole 71 through which the anchor bolt 2 passes is formed in the center of the fixing cap 7.

The body portion of the anchor bolt (2) is inserted through the anchor bolt through hole (71) of the fixing cap (7) and screwed into the fastening hole (51) of the anchor bracket (5).

At this time, the head portion of the anchor bolt (2) is caught on the bracket (3) on the front of the lightweight wall panel (1). Therefore, the bracket 3 is fixed to the lightweight wall panel 1 by the anchor bracket 5 supported on the back of the lightweight wall panel 1 (see Figure 19).

A second strap through hole 72 may be formed in the fixing cap 7 to allow the strap 6 to pass through and slide (FIGS. 5 (a) and (b) and FIG. 6).

The fixing cap (7) is guided by the strap (6) and can only slide to the front side, and its movement to the rear side is restricted so that the fixing cap (7) can be maintained in close contact with the lightweight wall panel (1). There must be. Accordingly, a toothed portion 61 inclined toward the front is formed on one surface of the strap 6 (FIG. 4), and the toothed portion 61 is formed within the second strap through hole 72 of the fixing cap 7. A locking hook 75 may be formed (FIG. 6).

Meanwhile, the anchor bracket (5) and the fixing cap (7), which are interconnected by the strap (6), are spaced apart from each other with the lightweight wall panel (1) interposed therebetween. In this case, the anchor bolt (2) inserted through the anchor bolt through hole (71) of the fixing cap (7) is accurately inserted into the fastening hole (51) of the anchor bracket (5) located on the rear side of the lightweight wall panel (1). It is not easy to insert and screw together.

Accordingly, a guide sleeve 73 is formed to protrude toward the front side around the anchor bolt through hole 71 of the fixing cap 7.

That is, a guide sleeve 73 whose interior communicates with the anchor bolt through hole 71 is formed protruding in front of the fixing cap 7, and the front end of the guide sleeve 73 is fastened to the anchor bracket 5. It is configured to be coupled around the ball (51).

Accordingly, the anchor bolt (2) inserted through the anchor bolt through hole (71) of the fixing cap (7) is guided by the guide sleeve (73) and is accurately guided to the fastening hole (51) of the anchor bracket (5). .

In addition, since the anchor hole 11 drilled in the field has an irregular diameter, it is inevitable that a gap occurs between the fixing cap 7 and the inner diameter of the anchor hole 11. Accordingly, in order to fix the fixing cap 7 so that it does not fall into the anchor hole 11, a flange 710 is formed protruding on the outside of the fixing cap 7 and can be supported on the front of the lightweight wall panel 1 ( Figure 2).

However, in this case, there is a problem in that the bracket (3) cannot be closely adhered to the front of the lightweight wall panel (1) due to interference of the flange, causing the bracket (3) to move during use.

Therefore, even if there is a gap between the outer diameter of the fixing cap 7 and the inner diameter of the anchor hole 11, the fixing cap 7 is attached to the outer peripheral surface of the fixing cap 7 so that the fixing cap 7 is firmly fixed within the anchor hole 11. 7) Multiple rows of wings 74 can be formed to protrude in the longitudinal direction (FIGS. 5 and 6).

The wing portion 74 is formed to be inclined higher toward the rear end so that the fixing cap 7 can easily enter the anchor hole 11 while the rear portion can be firmly fixed to the inner peripheral surface of the anchor hole 11.

In addition, the wing portion 74 has a cross-section that becomes more pointed toward the outer peripheral surface, so that it can be easily entered into the anchor hole 11 and firmly fixed.

When the anchor bolt (2) is rotated and advanced, the bracket (3) presses the fixing cap (7) so that the fixing cap (7) can be completely accommodated inside the anchor hole (11).

FIG. 8 is a perspective view showing the core material, FIG. 9 is a perspective view showing the coupling relationship between the core material and the anchor bracket body, and FIG. 10 is a perspective view showing the coupled state of the core material and the anchor bracket body.

As shown in FIGS. 8 to 10, the anchor bracket 5 is bent with a semicircular cross-section and has a fastening hole 51 in the center into which the front end of the anchor bolt 2 is screwed. A core material ( 5b).

In a conventional toggle anchor, the anchor bracket is formed in a semi-cylindrical shape, and the thin portions at both widthwise ends of the anchor bracket are supported in close contact with the back of the lightweight wall panel.

Therefore, if the pulling force of the strap or the fastening force of the anchor bolt is excessive, the side edge of the anchor bracket digs into the gypsum board of the lightweight wall panel, causing damage to the gypsum board, thereby preventing the anchor from being firmly fixed.

In order to solve this problem, the anchor bracket 5 can be composed of a semi-cylindrical anchor bracket body 5a and a core material 5b that is received and fitted inside the anchor bracket body 5a.

The anchor bracket body 5a can be formed by bending a metal plate through sheet metal processing or the like.

The core material 5b can be formed of a synthetic resin block that is inexpensive, lightweight, and has excellent formability.

The outer surface (i.e., the anchor bracket main body 5a side) of the core material 5b is formed in a shape and size corresponding to the inner peripheral surface of the anchor bracket main body 5a, and is configured to be in close contact with the inner surface of the anchor bracket main body 5a. can do.

The inner surface of the core material 5b (i.e., the back side of the lightweight wall panel 1) can be formed as a flat surface so that it is supported in close contact with the back of the lightweight wall panel 1.

By securing a large pressure area using the core material 5b, the anchor bracket 5 can be stably supported on the back of the lightweight wall panel 1 and damage to the lightweight wall panel 1 can be prevented.

A fastening hole 51 into which the front end of the anchor bolt 2 is screwed is formed in the center of the anchor bracket body 5a, and a fastening hole 51 of the anchor bracket body 5a is formed in the center of the core material 5b. ) and forms a first anchor bolt through-hole 511 through which the anchor bolt 2 penetrates.

To ensure that the anchor bracket (5) is firmly positioned without slipping while in close contact with the back of the lightweight wall panel (1), fixing tips are provided at both ends of the anchor bracket body (5a) in the width direction in the direction of the lightweight wall panel (1). (53) can be formed to protrude (FIGS. 3, 9, etc.).

The fixing tips 53 may be provided in a pair spaced apart from each other at the top and bottom and be driven into the back of the lightweight wall panel 1 from the outside of the anchor hole 11.

It is preferable that the fixing tip 53 has a sharp end on the lightweight wall panel 1 so that it can be easily embedded into the lightweight wall panel 1.

Figure 11 is a perspective view showing the coupling relationship between the fixing cap and the anchor bracket.

As shown in FIGS. 8 to 10 and 11, a plurality of fitting protrusions 731 are formed protruding at the front end of the guide sleeve 73, and are formed on the front side of the lightweight wall panel 1 of the core material 5b. A fitting groove 541 into which the fitting protrusion 731 is fitted may be formed around the first anchor bolt through hole 511.

The guide sleeve 73 simply serves to guide the anchor bolt 2 entering the fastening hole 51. Therefore, the front end of the guide sleeve 73 does not need to be firmly fixed to the anchor bracket 5, but simply communicates the anchor bolt through hole 71 and the fastening hole 51.

Therefore, by simply fitting the fitting protrusion 731 protruding at the front end of the guide sleeve 73 into the fitting groove 541 provided in the core material 5b, the anchor bolt through hole 71 and the fastening hole 51 are formed. They can be connected to each other along the same axis.

The fitting protrusion 731 and the fitting groove 541 can be formed to have an appropriate length to correspond to the thickness of the lightweight wall panel 1, and the fitting protrusion 731 is inserted into the fitting groove 541. You can combine them by adjusting the depth.

FIG. 12 is a perspective view showing a core material with a protruding coupling portion, FIG. 13 is a perspective view showing the coupling relationship between an anchor bracket provided with the core material of FIG. 12 and a fixing cap, and FIG. 14 is a drywall anchor shown in FIG. 13. This is a perspective view showing the state in which the anchor bolt is connected.

As shown in FIGS. 12 to 14, a ring-shaped coupling portion 54 is formed protruding around the first anchor bolt through hole 511 on the front surface of the core material 5b on the lightweight wall panel 1 side, The fitting groove 541 may be formed in the coupling portion 54.

In order to respond to changes in the thickness of the lightweight wall panel 1, the depth of the fitting groove 541 must be sufficiently secured.

Therefore, a coupling portion 54 can be formed to protrude on the front surface of the core material 5b on the side of the lightweight wall panel 1, and a fitting groove 541 can be formed in the coupling portion 54.

The coupling portion 54 may be formed to protrude around the first anchor bolt through hole 511 in a ring shape. The fitting groove 541 can be formed by cutting the coupling part 54 at a position corresponding to the fitting protrusion 731. The coupling portion 54 can be configured to protrude as much as the required depth of the fitting groove 541.

It is desirable that the inner diameter of the first anchor bolt through hole 511 formed in the coupling portion 54 be enlarged toward the entrance to guide the entry of the anchor bolt 2.

The coupling portion 54 is not only coupled to the front end of the guide sleeve 73, but is also inserted into the anchor hole 11 to fix the position of the anchor bracket 5.

The strap (6) may have its front end penetrate the anchor bracket (5) and be coupled to the anchor bracket (5) in a T-shape.

In the conventional toggle anchor, the strap is hinged to the anchor bracket, so a separate configuration is required to pass the anchor bracket through the anchor hole and then rotate the anchor bracket to form a T shape. Additionally, when the worker pulls the strap strongly, there is a problem that the strap is separated from the anchor bracket and the anchor bracket falls off.

Accordingly, in order to directly fix the strap 6 to the anchor bracket 5 without a separate coupling member, the front end of the strap 6 can penetrate the anchor bracket 5 and be coupled to each other to form a T shape.

For this purpose, a strap coupling hole 55 may be formed in the anchor bracket 5 into which the end of the strap 6 is inserted and locked (FIG. 3).

When the anchor bracket 5 is separately composed of the anchor bracket body 5a and the core material 5b, a strap coupling hole 55 is formed in the anchor bracket body 5a, and the first strap through hole is formed in the core material 5b. (551) can be formed (Figure 9). When the coupling portion 54 is formed to protrude from the core material 5b, the first strap through-hole 551 may be formed to penetrate the coupling portion 54 (FIG. 12).

The strap 6 penetrates the first strap through hole 551 of the core material 5b and then penetrates the strap coupling hole 55 of the anchor bracket body 5a, so that the strap (6) is supported by the core material 5b. 6) and the anchor bracket (5) can be stably maintained at a right angle.

The front end of the strap 6 may be provided with a locking portion 62 that is inserted into the strap coupling hole 55 (FIG. 4).

The locking portion 62 is formed larger than the strap coupling hole 55 and is supported by hanging on the outside of the anchor bracket 5. To this end, the strap (6) can be coupled to the anchor bracket (5) by inserting the rear end into the strap coupling hole (55) from the outside of the anchor bracket (5).

Accordingly, the strap (6) and the anchor bracket (5) are maintained in a T-shaped combined state, and the anchor bracket (5) can be rotated by the elasticity of the strap (6), making it easy to pass through the anchor hole (11). do.

In addition, even if the worker pulls the strap 6 strongly, there is no fear of the strap 6 and the anchor bracket 5 being separated because it is supported by the locking portion 62.

If the strap 6 is made of synthetic resin, it can be easily bent. Therefore, with the front end of the strap 6 coupled to the anchor bracket 5, the anchor bracket 5 is laid horizontally to form the anchor 4 in a straight line, and then the anchor hole of the lightweight wall panel 1 ( 11) can be passed (Figure 15). When the anchor bracket (5) passes through the anchor hole (11), the elasticity of the strap (6) rotates the anchor bracket (5) again so that it is perpendicular to the strap (6), thereby forming the ends of both side walls of the anchor bracket (5). can be in close contact with the back of the lightweight wall panel (1) (FIG. 16).

As shown in FIGS. 3 and 9, semi-cylindrical support portions 52 having a smaller outer diameter than the anchor bracket body 5a extend from both ends of the anchor bracket body 5a in the longitudinal direction, respectively, and the support portions Acupressure plates 521 that are vertically bent outward may be formed at ends of both side walls of 52, respectively.

Semi-cylindrical support parts 52 are extended from both longitudinal ends of the anchor bracket body 5a, and both widthwise ends of the support part 52 are vertically bent outward to provide an acupressure plate 521. .

The anchor bracket 5 can be supported on the back of the lightweight wall panel 1 by contacting the surface of the pressure plate 521.

At this time, when the acupressure plate 521 is vertically bent on both sides of the support portion 52, the overall width of the anchor bracket 5 increases due to the protrusion of the acupressure plate 521. In this case, in order for the anchor bracket (5) to pass through the anchor hole (11), the perforation diameter of the anchor hole (11) drilled in the lightweight wall panel (1) must be increased, resulting in poor constructability.

In order to prevent the overall width of the anchor bracket 5 from increasing due to the acupressure plate 521, a method of narrowing the gap between the two side walls of the semi-cylindrical anchor bracket body 5a may be considered. However, in this case, the entrance is narrow, making it difficult to directly fasten the anchor bolt (2) to the anchor bracket (5), and the diameter size of the anchor bolt (2) is limited.

Therefore, in order to easily fasten the anchor bolt (2) and avoid the need to enlarge the drilling diameter of the anchor hole (11), a support portion (52) provided with an acupressure plate (521) is provided at both longitudinal ends of the anchor bracket body (5a). It can be placed.

The support portion 52 has a smaller outer diameter than the central portion of the anchor bracket body 5a, and is provided with an acupressure plate 521 vertically bent outward at both ends in the width direction, that is, at the ends of both side walls.

The support portion 52 is supported on the back of the lightweight wall panel 1 outside the anchor hole 11.

Accordingly, even if the strap 6 is pulled with strong force, the anchor bracket 5 does not dig into the back of the lightweight wall panel 1 and is stably supported by the pressure of the support portion 52.

The pulling force generated by the strap 6 may be supported by the acupressure plate 521, and vertical sliding may be supported by the fixing tip 53.

The width of the support portion 52 including the acupressure plate 521 may be formed to be the same as the width of the anchor bracket body 5a.

Accordingly, despite the acupressure plate 521 being provided, the overall width of the anchor bracket 5 does not increase, so construction can be performed without increasing the drilling diameter of the anchor hole 11.

In addition, in order to firmly fix the core material 5b inside the anchor bracket body 5a, both ends of the core material 5b are hung on the support portion 52 to attach the core material 5b to the anchor bracket body 5a. A first locking hook 56 may be provided (FIGS. 9 and 12).

15 to 19 are diagrams showing the bracket fixing sequence using the drywall anchor of the present invention.

The present invention is for fixing fixtures such as shelves, furniture, and home appliances to drywall, art wall, etc., and can be constructed in the following order.

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

Then, the anchor bracket (5) coupled to the strap (6) in a T-shape is laid horizontally in a straight line with the strap (6) and the anchor bracket (5) is passed through the anchor hole (11) (FIG. 15) .

When the anchor bracket (5) passes through the anchor hole (11), the anchor bracket (5) rotates in the vertical direction again due to the elasticity of the strap (6), so that the anchor bracket (5) and the strap (6) form a T shape. It will be achieved. By pulling the strap (6), the anchor bracket (5) is brought into close contact with the back of the lightweight wall panel (1) so that the engaging portion (54) of the anchor bracket (5) is inserted into the anchor hole (11) (FIG. 16).

Next, the fixing cap 7 coupled to the strap 6 is advanced and inserted into the anchor hole 11 and fixed (FIG. 17). At this time, as the wing portion 74 of the fixing cap 7 is pushed into the anchor hole 11, the fixing cap 7 is firmly fixed within the anchor hole 11.

Afterwards, the portion of the strap 6 protruding to the outside of the fixing cap 7 is cut (FIG. 18).

Finally, the bracket (3) is placed in front of the anchor (4) of the lightweight wall panel (1), and the anchor bolt (2) is passed through the fixing cap (7) into the fastening hole (51) of the anchor bracket (5). Secure the bracket (3) by fastening (FIG. 19).

At this time, when the anchor bolt (2) is further tightened, the bracket (3) moves forward and pressurizes the fixing cap (7) so that the fixing cap (7) is completely accommodated in the anchor hole (11), and as a result, the bracket (3) is attached to the lightweight wall. It is installed tightly on the front of the panel (1) without any clearance.
