Description

Insert for fastening honeycomb panel and installation method of the same {Insert for fastening honeycomb panel and installation method of the same}

The present invention relates to an insert for fastening a honeycomb panel and a method of installing the same. More specifically, the present invention relates to an insert for fastening a honeycomb panel and a method for installing the same. More specifically, it is used in a honeycomb panel used for the purpose of lightening doors or sheet products, and is used to compensate for looseness that occurs when fastening screws necessary for assembly, thereby providing a sturdy insert. It relates to an insert for fastening a honeycomb panel that can secure screw fastening force and a method of installing the same.

Honeycomb panels, which are generally used in furniture, are manufactured by placing honeycomb-shaped honeycombs between the upper and lower plates and pressurizing them. As the honeycombs are inside, they are strong against load, lightweight, and have high durability.

In particular, in the case of doors, when using solid wood, there was a problem of bending or twisting due to the nature of wood being weak to humidity, and it was heavy and expensive, so honeycomb panels, which are light and durable, were often used for these doors. there is.

Meanwhile, for these doors, assembly of hinges or hardware/hardware is essential, and for this assembly, screw fastening is mainly used.

However, in the case of such honeycomb panels, there was a problem in the past where a firm bonding force could not be secured because looseness occurred due to the structural characteristics when fastening the screws required for assembly.

Here, the locking piece 210 includes an inner surface 211 coupled to the side of the first body 110, an inclined surface 212 formed to slope upward from the bottom to the upper part of the inner surface 211, and an inclined surface 212. ) and may be formed to include a locking surface 213 that is formed in a direction perpendicular to the side plate 21.

The locking piece 210 may be arranged to be inclined at a predetermined angle to face the tangential direction of the fastener 101 as shown in FIG. 2 to facilitate insertion into the hole formed in the honeycomb panel 20.

In detail, the locking piece 210 has an inner surface 211 coupled to the side of the protrusion 130 and may be located on the side of the protrusion groove 140.

Next, let's look at the folded wing portion 200.

3 and 4 are diagrams showing an insert 400 having a folded wing portion 200. The insert 400 includes a body portion 100 and a wing portion 200, and the wing portion ( 200) may be composed of a fold piece 220 that is coupled to the side of the body portion 100 and can be folded or unfolded.

First, in FIGS. 3 and 4, the body portion 100 may be composed of a substantially cylindrical first body 110 and a second body 120, where the first body 110 and the second body 120 have a substantially cylindrical shape. The body 120 is formed as one piece as in the above-described embodiment of FIG. 1, and the fastener 101 can be formed through the central portion of the first body 110 and the second body 120 along the longitudinal direction at the same time. , a protrusion 130 and a protrusion groove 140 may be formed on the outer surfaces of the first body 110 and the second body 120.

Here, unlike Figure 1, the protruding groove 140 is formed in the shape of a square groove in plan view, and the protruding groove 130 may be formed in a substantially fan shape. In addition, the protrusion 130 and the protrusion groove 140 are formed on the entire second body 120 and the upper part of the first body 110, so that the lower part of the first body 110 is formed on the outer surface as shown. It may be formed in a cylindrical shape, and an inlet groove 150 may be formed at the lower end.

The wing portion 200 has a lower end coupled to the side of the first body 110 and an upper end that is bent upward and can be folded or unfolded. When the fastening screw 10 is fastened, it unfolds (opens) and comes into contact with the side plate 21. A fold piece 220 may be formed.

In detail, the fold piece 220 has a rectangular side shape, is formed in a plurality of pieces arranged radially along the circumferential direction of the first body 110, and is bent obliquely in all directions, and may be located on the side of the protruding groove 140. .

Below, we will look at a method of installing an insert for fastening a honeycomb panel according to an embodiment of the present invention.

Prior to this, the inserts 300 and 400 for fastening the honeycomb panel are as described above, and a description of their detailed configuration will be omitted.

First, FIGS. 5 and 6 show a method of installing an insert having spiral-type wings 200, and FIGS. 7 and 8 show a method of installing an insert having fold-type wings 200. Here, the installation method of the inserts 300 and 400 is basically the same even if the wing portion 200 has different embodiments.

Accordingly, looking at the insert installation method, first, as shown in FIGS. 5 and 7, an insert of a set depth is installed on the side plate 21 and the honeycomb 22 through a boring (drilling) process on the honeycomb panel 20. Form a fastener (hole).

Then, as shown in FIGS. 6 and 8, when the insert is inserted with the adhesive 30 using the insert fastener, the wing portion 200 is unfolded. Meanwhile, if the wing portion 200 is not unfolded, the wing portion 200 can be unfolded by pressing the protruding groove portion 140 with a tool such as an awl. After the wings are unfolded, the adhesive 30 hardens and the fastening screw 10 is fastened with the insert fastener at the site.

Accordingly, forming an insert fastener with a set depth for the side plate and the honeycomb through a boring process on a honeycomb panel in which a honeycomb is arranged between a pair of side plates, and injecting adhesive into the insert fastener and then fastening. It may include the step of inserting an insert for fastening a honeycomb panel to which a screw is fastened.

9 and 10 are front views showing an embodiment in which an adhesive piece 160 is provided on the insert, and the insert may further include an adhesive piece 160 coupled to the outer surface of the body portion 100.

The adhesive piece 160 serves to improve the fixing force of the insert to the adhesive 30 by increasing the contact area with the adhesive 30 and increasing the adhesive force with the adhesive 30.

Referring to FIG. 9, one end of the adhesive piece 160 is coupled to the lower outer peripheral side of the body portion 100 so as to be in contact with the adhesive 30, and the other end is in contact with the body portion 100 to be separated from the body portion 100. It can be.

Furthermore, the adhesive piece 160 is formed to be bendable as shown in FIG. 10, so that when the insert is inserted, it is folded to facilitate insertion into the hole. When the insert is rotated after insertion, the other end unfolds and the adhesive 30 is formed. When it hardens, the insert can be more firmly adhered to the adhesive 30.

Accordingly, the adhesive piece 160 can be expanded by rotating the body portion 100 clockwise by a certain angle after inserting the insert together with the adhesive 30, thereby increasing the adhesive force with the adhesive 30. Meanwhile, as shown, the other end of the adhesive piece 160 is located clockwise with respect to one end, so that when the body portion 100 rotates clockwise, the adhesive piece 160 opens further, so that when the fastening screw 10 is fastened, the body portion 100 ) can be used to prevent rotation.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached patent claims.
