Description

Double-glazed glass with improved earthquake resistance through buffer packing

[0001] The present invention relates to a double-layer glass having improved earthquake resistance, which is constructed by laminating a plurality of glass plates.

[0002] Typically, double-glazed glass is made by laminating multiple glass plates with a thin layer between them to improve the insulation and durability of the glass.

[0003] Double glazing can be installed in a frame and used as a fixed or movable window, or used in a door.

[0004] However, since double-glazed windows are installed by being fitted into a frame, there was a problem that when an earthquake occurred, the frame and double-glazed windows would collide, or the vibration transmitted through the frame would be transferred to the double-glazed windows, causing the double-glazed windows to break.

[0005] To solve these problems, a patent registration publication No. 10-1793601 (announced on November 6, 2017) entitled “Earthquake-resistant window structure” was published.

[0006] The above-mentioned conventional earthquake-resistant window structure is a window structure including a double-glazed window made of a plurality of single-glazed windows spaced apart from each other with a spacer therebetween, and a sash that finishes the perimeter of the double-glazed window, wherein an integral buffer cap made of an elastic material is installed between the sash and the double-glazed window to cover each corner of the double-glazed window, the double-glazed window is cut to fit the window size and provided, and each cut cross-section is processed to be rounded so as not to cause breakage scratches, and the sash is configured to be embedded and fixed in the wall of the structure.

[0007] This conventional earthquake-resistant window structure was able to prevent the double-glazed windows from being damaged by installing a buffer cap made of elastic material between the double-glazed windows and the sash, thereby cushioning the gap between the double-glazed windows and the sash with the elastic force of the buffer cap in the event of an earthquake.

[0008] However, since the conventional earthquake-resistant window structure only supports the double-glazed glass with a buffer cap, there is a limit to the earthquake vibration that can be blocked by the buffer cap, so there was a problem that it was easily damaged.

[0009] In addition, when relatively large vibrations occur in conventional earthquake-resistant window structures, not only does the double-glazed glass break when the edge of the buffer cap comes into contact with it, but the buffer cap is compressed by elastic force due to the load of the double-glazed glass, and then separates and returns, colliding with the double-glazed glass and causing damage.

[0010] In addition, the conventional earthquake-resistant window structure had a problem in that the earthquake resistance of the double-glazed window was reduced when the internal space of the buffer cap was relatively large due to the double-glazed window moving.

[0011] The present invention has been devised to solve the above-mentioned problems, and the problem to be solved by the present invention is to provide a double-layer glass having improved earthquake resistance by installing a buffer packing between a glass laminate and a glass frame to buffer vibrations by the buffer packing, thereby improving earthquake resistance.

[0012] In addition, the present invention aims to provide a double-glazed glass having improved earthquake resistance by a buffer packing in which a grooved buffer portion that is elastically deformed when fitted into a glass frame is formed protrudingly in a packing body in which a glass laminate is settled in the buffer packing, and the grooved buffer portion fills the gap between the frame grooves so as to stably support the glass laminate even in a relatively wide frame groove.

[0013] In addition, the present invention provides a double-glazed glass having improved earthquake resistance by a cushioning packing that can minimize vibration transmitted from the glass frame to the glass laminate by configuring the groove buffer part to be partially cut through the cut groove part in the packing body and thereby configuring the groove buffer part to behave differently from the packing body, thereby enabling the relative behavior of the glass frame with respect to the glass laminate supported on the packing body according to the vibration of the earthquake.

[0014] In addition, the present invention provides a double-glazed glass having improved earthquake resistance by a buffer packing in which a buffer packing is provided with a buffer portion, and the buffer portion is installed in a form in which the buffer portion is elastically deformed and inserted between the packing body and the buffer portion, so that even if the buffer packing and the glass frame move relative to each other, the glass laminate is prevented from colliding with the glass frame and being damaged.

[0015] In order to achieve the above-described object, a double-glazed glass having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention comprises a glass laminate in which a plurality of glass plates are laminated with a spacer therebetween, a glass frame having a frame groove formed in which the glass laminate is fitted and installed, and a buffer packing formed of an elastic body that buffers between the glass laminate and the frame groove, wherein the buffer packing comprises a packing body positioned in the depth direction of the frame groove in the glass laminate to buffer between the glass frame and the glass laminate, and a groove buffer portion formed by extending from the packing body in the depth direction of the frame groove so as to fill and buffer the gap between the packing body and the frame groove while being elastically deformed when the glass laminate is fitted into the frame groove.

[0016] In order to buffer vibrations by allowing the glass frame supported by the grooved buffer to move independently from the glass laminate while the load of the glass laminate is applied to the packing body, only a portion of the grooved buffer may be attached to the side of the packing body, and the remaining portion extending downward may include a cut groove that is separated.

[0017] The above packing body may include a hollow portion formed through the packing body so that the glass frame, to which vibration is transmitted from the glass laminate mounted on the packing body, behaves differently from each other to buffer the vibration.

[0018] The above-mentioned buffer packing may include a buffer portion protruding from the packing body toward the edge portion to prevent the glass laminate inserted into the frame home from colliding with the edge portion of the frame home due to vibration.

[0019] The above-mentioned edge buffer may have a length that is exposed from the edge of the packing body to the outside so that it is inserted by being elastically deformed and forcibly fitted into the gap between the edge of the frame home and the glass laminate facing each other.

[0020] According to the present invention, a cushioning packing that cushions by elastic force between a glass frame that supports a glass laminate and the glass laminate is installed, so that the cushioning packing cushions the vibration of an earthquake, thereby preventing the glass laminate from being broken. In addition, the cushioning packing is configured with a groove buffering part that is inserted into a frame groove in an elastically deformed state, so that the glass laminate can be supported even in a relatively wide frame groove, thereby improving earthquake resistance.

[0021] In addition, since the glass laminate is secured to the packing body and the grooved buffer portion supported by the glass frame is cut and positioned by the cut groove portion, the glass laminate is held in place by the load, and only the glass frame moves, thereby blocking vibration transmitted to the glass laminate, thereby improving earthquake resistance.

[0022] In addition, the present invention can effectively dampen vibrations and improve earthquake resistance because a hollow portion is formed in the packing body, allowing the glass laminate to flow when relatively strong vibrations occur in the frame groove.

[0023] In addition, the present invention comprises a buffer packing having a buffer portion that is elastically deformed and inserted between the buffer packing and the glass laminate, thereby preventing the glass laminate from being damaged by preventing the collision between the buffer portion and the glass laminate during vibration due to an earthquake. In addition, even if the glass frame and the glass laminate behave differently, vibration can be cushioned by the elastically deformed buffer portion, thereby improving earthquake resistance.

[0026] Fig. 3 is a cross-sectional side view of a laminated glass having improved earthquake resistance by a buffer packing according to an embodiment of the present invention, showing a cross-section of the lower part and showing a state in which a glass laminate is installed on a glass frame.

[0027] FIG. 4 is a schematic front view of a double-glazed window having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention, and is a drawing for explaining the installation position of the buffer packing.

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.

[0029] As shown in FIGS. 1 to 3, the double-layer glass (100) having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention may include a glass laminate (110).

[0030] This glass laminate (110) may be in the form of a plurality of glass plates (111) laminated to increase the strength of the glass while enhancing the insulation.

[0031] The glass laminate (110) is formed by stacking a plurality of glass plates (111) in parallel at preset intervals, installing a spacer (113) around the circumference between the plurality of glass plates (111), and installing a spacer seal (115) around the spacer (113) to seal the interior.

[0032] A desiccant or butyl, etc. may be installed in the gap (113) to prevent air from circulating between the facing glass plates (111). The gap (113) may also be formed of aluminum or TPS depending on the insulating properties.

[0033] In the embodiment, the glass laminate (110) is composed of two glass plates (111), but it is of course possible to have a glass laminate composed of more than two glass plates (111) overlapping each other.

[0034] The glass laminate (110) can be fixedly installed on a glass frame (200), and the glass frame (200) can be installed along the edge of the glass laminate (110), and a frame groove (210) into which the glass laminate (110) is inserted and installed can be formed along the inner circumference of the glass frame (200).

[0035] The glass frame (200) may be a window frame installed on a door frame or a door frame installed on a door frame, depending on the window or general door.

[0036] The glass frame (200) can perform the function of protecting the edge of the glass laminate (110) by wrapping the relatively weak edge portion of the glass laminate (110) and at the same time fixing and installing the glass laminate (110).

[0037] A frame groove (210) can be formed on the inner surface of the glass frame (200) so that a glass laminate (110) can be fitted and fixed.

[0038] The glass frame (200) can be installed in a fixed form with a glass laminate (110) or can be installed on a window or door to open and close by sliding or rotating.

[0039] The glass frame (200) is usually in the shape of a square frame, but may have a polygonal shape other than a square, and may also be in the shape of a circle or an oval.

[0040] The glass frame (200) can be assembled or attached to each other in a polygonal shape while being fitted to each side of the glass laminate (110).

[0041] As shown in FIGS. 2 to 4, the double-layer glass (100) having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention may include a buffer packing (130).

[0042] This buffer packing (130) can prevent breakage of the glass laminate (110) by buffering the glass laminate (110) when an earthquake occurs.

[0043] The buffer packing (130) is installed around a part or the entire circumference of the glass laminate (110) and supports the glass laminate (110) in the glass frame (200) by elastic force, thereby buffering the vibration of an earthquake.

[0044] For example, as shown in FIG. 4, the buffer packing (130) may be installed on the entire periphery of the glass laminate (110) as shown in (a) of FIG. 4, or may be installed on only one of the upper, lower, left, and right edges of the glass laminate (110) as shown in (b) of FIG. 4, and a known packing may be installed on the rest, or may be installed only on the corner portion of the glass laminate (110) as shown in (c) of FIG. 4, and may be installed on the glass laminate (110).

[0045] The buffer packing (130) can be formed of urethane, silicone, synthetic resin, rubber, etc. to buffer vibrations, and can be inserted into the frame groove (210) while attached to the glass laminate (110) to buffer vibrations transmitted from the frame groove (210) to the glass laminate (110).

[0046] The buffer packing (130) may include a packing body (131), a home buffer (133), and a border buffer (135).

[0047] The packing body (131) is positioned around the periphery of the glass laminate (110) and can buffer the vibration of an earthquake transmitted vertically from the glass frame (200) to the glass laminate (110).

[0048] The packing body (131) can be formed in a square shape, and the packing body (131) can be formed with a long length along the longitudinal direction of the frame home (210) to protect the edge of the glass laminate (110).

[0049] In the center of the packing body (131), a hollow portion (131a) through which air is introduced and for cushioning by air can penetrate along the length of the packing body (131).

[0050] Here, the hollow portion (131a) lowers the rigidity of the packing body (131) to improve the vibration damping property, and at the same time, allows the glass laminate (110) to vibrate in the glass frame (200) when relatively large vibrations occur, so that as the glass laminate (110) is suppressed by the glass frame (200), the vibration transmitted to the glass frame (200) is entirely transferred to the glass laminate (110), thereby preventing the glass laminate (110) from being broken.

[0051] The home cushioning part (133) is elastically deformed by the glass laminate (110) inside the frame home (210), and the gap between the frame home (210) and the glass laminate (110) is minimized by the home cushioning part (133), thereby preventing the glass laminate (110) from being easily shaken by a small external force such as wind in the glass frame (200).

[0052] The groove buffer (133) can be formed to protrude from the packing body (131) in the depth direction of the frame groove (210) to have a length longer than the length of the packing body (131), and the groove buffer (133) is elastically deformed when the glass laminate (110) is fitted into the frame groove (210), thereby filling the gap between the frame groove (210) and the glass laminate (110), thereby preventing the glass laminate (110) from shaking in the glass frame (200) due to a relatively small external force such as wind.

[0053] For example, if the width of the frame groove (210) is greater than the thickness of the glass laminate (110), there is a risk of the glass laminate (110) being easily shaken and broken even by an external force such as a small wind, so the groove buffer (133) may also perform the function of filling the gap between the frame groove (210) and the glass laminate (110).

[0054] In addition, when the glass laminate (110) moves to one side in the frame home (210), the glass laminate (110) is not separated from the glass frame (200) and is maintained in contact with the frame home (210) without being separated by the shape restoring force of the elastically deformed groove buffer (133), so that the impact of the glass laminate (110) colliding with the frame home (210) upon return can be reduced.

[0055] The groove buffer portion (133) can be formed to extend toward the frame groove (210) on both sides in the width direction of the packing body (131), and the groove buffer portion (133) can be connected to the packing body (131) so that only a portion of the groove buffer portion (133a) is attached to the side of the packing body (131) through a cut groove portion (133a) partially cut out of the packing body (131) so that the groove buffer portion (133) can be easily elastically deformed when the groove buffer portion (133) is pressed, and the remaining portion located in the frame groove (210) can be separated from the packing body (131).

[0056] Since the groove buffer (133) is partially separated from the packing body (131), it performs the function of supporting the glass laminate (110) in the frame groove (210), and at the same time, especially when a relatively large earthquake vibration occurs, since the packing body (131) can move in the groove buffer (133), the glass laminate (110) supported by the packing body (131) maintains its position in the direction of gravity due to its own weight, and only the glass frame (200) supported by the groove buffer (133) moves, thereby preventing the glass laminate (110) from being damaged by the vibration being transferred to the glass laminate (110) through the glass frame (200).

[0057] The edge buffer (135) extends from the packing body (131) to the part where the edge (211) of the frame home (210) is located, so that when an earthquake occurs, the glass laminate (110) in the glass frame (200) can be shaken by vibration and the edge (211) of the frame home (210) can be prevented from being damaged by collision.

[0058] The edge buffer (135) is formed to have a length that protrudes more than the edge (211) between the edge (211) of the frame home (210) and the glass laminate (110), and by pressing the edge (211) from above, it can be inserted and positioned between the frame home (210) and the edge (211) in a form in which it is forcibly inserted between the glass laminate (110) and the edge (211) as if it were elastically deformed and crumpled.

[0059] Here, the edge buffer (135) is formed on both sides in the width direction of the packing body (131) to have a longer length than the edge portion (211), so that each edge buffer (135) is positioned between the edge portion (211) facing each other and the surface of the glass laminate (110), thereby preventing the glass laminate (110) from colliding with the edge portions (211) on both sides.

[0060] Since the edge buffer (135) is forcibly folded and inserted between the edge (211) and the glass laminate (110) as if folded in a zigzag pattern, it prevents the collision between the glass laminate (110) and the edge (211), and at the same time, when an earthquake vibration greater than the elastic force capable of cushioning elasticity occurs in the buffer packing (130), the glass laminate (110) in the glass frame (200) maintains its relative position due to the load and only the glass frame (200) shakes, thereby minimizing the transmission of vibration to the glass laminate (110).

[0061] At the end of the edge buffer (135), a edge sealing portion (135a) having a width greater than the gap between the glass laminate (110) and the edge portion (211) is formed, so that the edge buffer (135) is inserted between the glass laminate (110) and the edge portion (211) and the edge sealing portion (135a) is elastically deformed and forcibly inserted, thereby finishing the outer side of the glass laminate (110) and the edge portion (211) to seal the glass laminate (110) and the edge portion (211) so as to block the inflow of foreign substances between the glass laminate (110) and the edge portion (211).

[0062] Of course, after the edge buffer (135) is elastically deformed and inserted between the glass laminate (110) and the edge portion (211), a sealing material (230) such as silicone is applied to the upper portion to prevent the edge buffer (135) inserted between the glass laminate (110) and the edge portion (211) from being easily separated from the glass laminate (110) and the edge portion (211).

[0063] Let us explain the actions and effects between each component described above.

[0064] The double-layer glass (100) having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention is configured as a glass laminate (110) in which a plurality of glass plates (111) are arranged in parallel and a gap (113) or a gap seal (115) is installed along the perimeter of the glass plates (111) between the plurality of glass plates (111).

[0065] A glass frame (200) is installed around the periphery of the glass laminate (110) to protect the periphery of the glass laminate (110) and secure the glass laminate (110), and a frame groove (210) into which the glass laminate (110) is inserted is formed on the inner periphery of the glass frame (200).

[0066] Between the glass laminate (110) and the glass frame (200), a buffer packing (130) is installed to buffer earthquake vibrations. The buffer packing (130) may be installed on the glass frame (200) in a form in which it is installed, for example, on the entire perimeter of the glass laminate (110), on each corner of the glass laminate (110), or on the lower edge of the glass laminate (110) and a known packing is installed on the remaining edges.

[0067] The buffer packing (130) can be inserted into the frame groove (210) in a state where the packing body (131) is bonded to the periphery of the glass laminate (110) by an adhesive or adhesive tape, and a groove buffer portion (133) is formed on both sides of the width direction of the packing body (131) so as to have a length longer than the length of the packing body (131) in the depth direction of the frame groove (210).

[0068] When the glass laminate (110) is fitted into the frame groove (210), the groove buffer (133) is elastically deformed and crushed, and is pressed against the side of the frame groove (210), thereby filling the gap between the glass laminate (110) and the frame groove (210), thereby preventing the glass laminate (110) from shaking in the frame groove (210).

[0069] The home cushioning part (133) is formed in the packing body (131) in a state in which one end is connected to the packing body (131) and the other end is separated, so that the home cushioning part (133) is located on the side of the packing body (131) and is partially separated from the packing body (131) by the cut-out groove (133a).

[0070] In the opposite direction to the direction in which the groove buffer portion (133) is formed in the packing body (131), a border buffer portion (135) is formed to protrude from both sides in the width direction of the packing body (131) to prevent the frame portion (211) of the frame groove (210) and the glass laminate (110) from contacting each other.

[0071] The edge buffer (135) formed by protruding from the packing body (131) is formed to have a length that is exposed from the edge portion (211) when the glass laminate (110) is inserted into the edge groove, and the edge buffer (135) is elastically deformed and folded to be forcibly inserted and positioned between the edge portion (211) and the glass laminate (110).

[0072] At the end of the frame portion (211), a frame sealing portion (135a) is formed, and the frame home (210) can be sealed by the frame sealing portion (135a) in which the frame portion (211) and the outer side of the glass laminate (110) are forcibly fitted together, and a sealing material (230) is applied to the upper portion of the frame sealing portion (135a) to prevent the frame sealing portion (135a) from coming off.

[0073] The double-layer glass (100) having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention configured as described above prevents breakage of the glass laminate (110) by blocking the transmission of minute vibrations to the glass laminate (110) by absorbing the vibrations caused by an earthquake through the overall elasticity of the buffer packing (130).

[0074] And, when the vibration becomes stronger, the elastic body is elastically deformed through the hollow portion (131a) of the elastic body to cushion the vibration, and the vibration occurring laterally is elastically deformed through the groove buffer portion (133) to cushion the vibration, thereby preventing the glass laminate (110) from colliding with the frame groove (210) or from being transmitted to the glass laminate (110) when a relatively strong vibration is transmitted, thereby preventing the glass laminate (110) from being damaged.

[0075] At this time, since the elastic body and the groove buffer (133) have different thicknesses and sizes and different elastic deformations, they can effectively buffer vibrations of various sizes and prevent breakage of the glass laminate (110).

[0076] Even when a vibration larger than the size that can be damped by the elasticity of the buffer packing (130) occurs, the elastic body and the groove buffer (133) are only partially formed as one piece by the cut groove (133a), so that the glass laminate (110) can be positioned in its position by the load, and only the glass frame (200) can relatively move differently by the groove buffer (133) to dampen the vibration.

[0077] Of course, even if the glass laminate (110) is tilted to one side in the frame home (210), the elastically deformed home buffer (133) spreads out or folds elastically to maintain contact between the two, so that the glass laminate (110) can be prevented from being damaged by the impact that occurs when they are completely separated and then come into contact again.

[0078] In addition, since a crumpled edge buffer (135) is inserted between the glass laminate (110) and the edge portion (211) of the frame home (210) when vibration occurs, even if the glass laminate (110) and the glass frame (200) behave differently to prevent vibration, the glass laminate (110) can be prevented from colliding with the edge portion (211) of the glass frame (200) and being damaged.

[0079] Here, the edge buffer (135) is inserted and positioned between the edge (211) and the glass laminate (110) in a crumpled shape, so that when the edge buffer (135) is deformed, the contact between the edge (211) and the glass laminate (110) is elastically deformed, thereby improving the contact between the two and enhancing the dustproofness.

[0080] For example, when the glass laminate (110) moves to one side of the frame home (210), the edge buffer (135) located on one side is compressed, and the edge buffer (135) in the opposite direction, where the gap between them widens, tries to unfold from a folded state due to elastic deformation, so that the two continuously maintain contact and cushion vibrations, thereby preventing breakage of the glass laminate (110) due to the impact of re-contact in a completely separated state.

[0081] Accordingly, the double-layer glass (100) having improved earthquake resistance by means of a buffer packing according to an embodiment of the present invention can improve the earthquake resistance of the glass laminate (110) by installing a buffer packing (130) between the glass frame (200) and the glass laminate (110) so that the vibration of an earthquake transmitted to the glass laminate (110) through the glass frame (200) is buffered and dissipated by the buffer packing (130).

[0082] In addition, the present invention can improve earthquake resistance by forming a hollow portion (131a) in the packing body (131) so that the glass laminate (110) can move in the glass frame (200), so that even if relatively large vibrations occur, only the glass frame (200) vibrates and the glass laminate (110) can be positioned in its current position by the load, thereby exhibiting relative behavior.

[0083] In addition, since the present invention is configured in a form in which the grooved buffer portion (133) in the buffer packing (130) is cut by the cut groove portion (133a), when a relatively large earthquake vibration occurs, the glass laminate (110) maintains its position by the load, and only the glass frame (200) vibrates, thereby improving earthquake resistance.

[0084] In addition, since the present invention configures a buffer packing (130) with a buffer portion (135) and the buffer portion (135) is inserted and positioned between the buffer portion (211) of the glass frame (200) and the glass laminate (110), it is possible to prevent breakage caused by the glass laminate (110) colliding with the edge of the glass frame (200) due to earthquake vibration, and by allowing relative movement of the glass laminate (110) in the glass frame (200), it is possible to prevent breakage of the glass laminate (110) as the vibration of the glass frame (200) is entirely transferred to the glass laminate (110).

[0085] Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and includes all changes and modifications that can be easily modified and deemed equivalent by a person having ordinary skill in the art to which the present invention pertains from the embodiments of the present invention.

In paragraph 1, The above packing body A double-glazed glass having improved earthquake resistance by means of a buffer packing, characterized in that the glass frame, to which vibration is transmitted from the glass laminated body mounted on the packing body, has a hollow portion formed through the packing body so that vibration is buffered by different behavior.

4. In paragraph 1, The above buffer packing A double-glazed glass having improved earthquake resistance by means of a buffer packing, characterized in that it includes a buffer packing portion protruding from the packing body toward the edge portion to prevent the glass laminate inserted into the frame home from colliding with the edge portion of the frame home due to vibration.

5. In paragraph 4, The above border buffer A double-glazed glass having improved earthquake resistance by means of a buffer packing, characterized in that the packing body has a length that is exposed to the outside from the edge portion so that it is inserted by being forced-fit while elastically deforming in the gap between the edge portion of the frame home and the facing glass laminate.
