Description

Technical Field

[0001] This invention relates to a multilayer glass with improved seismic performance, which is composed of multiple stacked glass plates. Background Technology

[0002] Generally speaking, laminated glass is made by stacking multiple glass panes together to improve the heat insulation and durability of the glass.

[0003] Duplex glass panels are installed on a frame and can be used as fixed or movable windows, or as doors.

[0004] However, since laminated glass is installed sandwiched between frames, during an earthquake, the frame and laminated glass may collide, or the vibration transmitted through the frame may be transferred to the laminated glass, causing the laminated glass to break.

[0005] To address these issues, the "Earthquake-resistant Window Structure" project, previously published as Patent Registration No. 10-1793601 (November 6, 2017), was initiated.

[0006] The traditional earthquake-resistant window structure includes a multi-pane glazed window composed of multiple single-pane glass panes separated by a baffle, and a window frame that encloses the perimeter of the multi-pane glazed window. Between the window frame and the multi-pane glazed window, an integrated buffer cap made of elastic material covers the beveled edges of the multi-pane glazed window. The multi-pane glazed window is cut according to the window size, and the cross-section of each cut is cut into a groove to avoid dents. The window is also processed on the wall to fix the wall in place.

[0007] This traditional earthquake-resistant window structure uses a buffer cap made of elastic material between the double-glazed glass and the window frame. During an earthquake, the elastic force of the buffer cap can cushion the damage to the double-glazed glass.

[0008] However, since traditional earthquake-resistant window structures only rely on buffer caps to support the glazing, the earthquake vibrations that the buffer caps can withstand are limited, and they are prone to damage.

[0009] In addition, the traditional earthquake-resistant window structure has the following problem: if a relatively large vibration occurs, the edge of the buffer cap will come into contact with the laminated glass, which will not only cause the laminated glass to break, but the buffer cap will also be damaged by impact and repair when it is compressed by elastic force under the load of the laminated glass, and collide with the laminated glass.

[0010] In addition, in the past, when the internal space of the buffer cap of the earthquake-resistant window structure was relatively large, the earthquake resistance of the glazing glass decreased as the glazing glass was moved. Summary of the Invention

[0011] The problem that the invention aims to solve

[0012] The present invention is proposed to solve the aforementioned problem. The problem to be solved by the present invention is to provide a buffer pad between the glass layer and the glass frame to buffer vibration, thereby providing a laminated glass with improved seismic performance through the buffer pad.

[0013] In addition, the purpose of this invention is to provide a cushioned packaging in which, when the packaging body in which the glass layer is placed is inserted into the glass frame, a grooved cushioning part that protrudes and forms an elastically deformable part fills the gap of the middle frame groove, thereby providing a cushioned packaging that can stably support the glass layer in a relatively wide frame groove and improve the shock resistance of the laminated glass.

[0014] Furthermore, the purpose of this invention is to configure the groove buffer portion to have a partial cut in the package body via the cut groove portion, thereby allowing the groove buffer portion to perform different actions on the package body. This allows the glass layer supported on the package body to perform relative actions to the glass frame according to the vibration of an earthquake, thereby minimizing the vibration transmitted from the glass frame to the glass layer, thus providing a shock-resistant buffer layer and a glass layer with improved shock resistance.

[0015] In addition, the purpose of this invention is to form an edge buffer portion on the cushioning packaging, so that the edge buffer portion is installed between the packaging body and the edge portion in the form of elastic deformation clamping. Therefore, even if the cushioning packaging and the glass frame move relative to each other, the edge portion of the glass frame will have a glass layer. This provides a cushioning packaging that can prevent the glass frame from being damaged by collision, thereby improving the shock resistance of the multilayer glass.

[0016] means for solving problems

[0017] To achieve the aforementioned goal, according to an embodiment of the present invention, the shock resistance of double-glazed windows is improved by a buffer pad. This includes a glass layer consisting of multiple glass sheets stacked with gaps between them, a glass frame formed by a frame groove clamped between the glass layers, and a buffer pad formed by an elastic body that buffers the space between the glass layers and the frame groove. The buffer pad includes a buffer pad between the glass layers and the frame groove in the depth direction of the frame groove, and a buffer pad between the glass layers in the frame groove. Upon insertion, with elastic deformation, a groove-shaped buffer portion extending from the encapsulation body towards the depth direction of the frame groove fills the gap between the encapsulation body and the frame groove, providing cushioning.

[0018] The cushioning pad may include, when the glass layer load is applied to the packaging body, a portion of the grooved cushioning portion is cut open on the packaging body to allow the glass frame supported on the grooved cushioning portion to move separately from the glass layer to cushion vibration, including a cut groove portion of a separated cut groove portion.

[0019] The packaging body may include a hollow portion formed throughout the packaging body so that the glass frame, which transmits vibrations in the glass layer mounted on the packaging body, can cushion the vibrations through different actions.

[0020] The cushioning pad may include an edge cushioning portion extending from the packaging body toward the edge portion to prevent the glass layer inserted into the frame groove from colliding with the edge portion of the frame groove due to vibration.

[0021] The edge buffer portion elastically deforms and is forcibly inserted within the relative gap between the edge of the frame groove and the glass layer, and may have a length exposed outward from the edge in the encapsulation body.

[0022] Invention Effects

[0023] According to the present invention, an elastic force buffer pad is provided between the glass frame supporting the glass layer and the glass layer. The buffer pad can buffer seismic vibrations and prevent damage to the glass layer. The buffer pad is composed of a groove buffer part inserted into the frame groove in an elastic deformation state. The glass layer can also be supported in a relatively wide frame groove, thereby improving seismic performance.

[0024] In addition, the present invention can also improve the seismic performance because the glass layer is placed on the packaging body, and the groove buffer part supported by the glass frame is cut and positioned by the groove. Therefore, the glass layer is fixed in position by the load, and only the glass frame moves, thus blocking the vibration transmitted by the glass layer.

[0025] In addition, the present invention forms a hollow part in the packaging body, which allows the glass layer to flow when relatively strong vibrations occur in the frame groove, thus effectively isolating vibrations and improving shock resistance.

[0026] In addition, the present invention consists of an edge buffer portion on the buffer pad that is elastically deformed and clamped between the edge portion and the glass layer. During earthquake vibration, it can prevent the collision between the edge portion and the glass layer and prevent damage to the glass layer. Moreover, even if the glass frame and the glass layer have different movements, the vibration can be buffered by the elastically deformable edge buffer portion, thereby improving the seismic resistance.

[0040] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0041] like Figures 1 to 3 As shown, the multilayer glass 100 with improved shock resistance through the buffer pad in this embodiment of the invention may include a glass layer 110.

[0042] The glass laminate 110 can be in the form of multiple glass plates 111 stacked together to increase the strength of the glass while increasing its thermal insulation.

[0043] When multiple glass plates 111 are neatly stacked together at a preset interval, a sealing strip 113 is provided around the middle of the multiple glass plates 111 in the glass laminate 110, and a sealing strip 115 can be provided around the sealing strip 113 to keep the interior sealed.

[0044] A desiccant or butyl acetate may be applied to the rod 113 to prevent air from flowing between the opposing glass plates 111. Depending on the insulation properties, the rod 113 may be made of aluminum or TPS.

[0045] In this embodiment, the glass laminate 110 consists of two glass plates 111, but it can of course be composed of more than two glass plates 111 overlapping each other.

[0046] The glass layer 110 can be fixedly installed on the glass frame 200. The glass frame 200 can be installed along the edge of the glass layer 110. The frame groove 210 for inserting the glass layer 110 into the glass frame 200 can be formed along the inner periphery of the glass frame 200.

[0047] Depending on whether it is a window or a regular door, the glass frame 200 can also be a window frame installed on a door frame or a door frame installed on a door frame.

[0048] The glass frame 200 can wrap around the relatively weak edge portion of the glass layer 110, protecting the edge of the glass layer 110, while also performing the function of fixing the glass layer 110 in place.

[0049] A frame groove 210 can be formed around the bottom of the glass frame 200 to clamp and fix the glass layer 110.

[0050] The glass frame 200 can be fixedly installed on the glass layer 110, or it can be installed on a window or door with a sliding or rotating switch.

[0051] Glass frames 200 are usually in the form of square frames, but can be polygonal in other shapes, or in the form of circles or ovals.

[0052] The glass frame 200 can be assembled or attached to each other while being sandwiched between the sides of the glass layer 110 to form a polygon.

[0053] like Figures 2 to 4 As shown, the laminated glass 100 with improved shock resistance through the buffer pad in this embodiment of the invention may include a buffer pad 130.

[0054] The buffer pad 130 can cushion the glass layer 110 during an earthquake, preventing the glass layer 110 from breaking.

[0055] The buffer pad 130 is installed on the perimeter of the glass layer 110 or the entire perimeter, and can use elastic force to support the glass layer 110 on the glass frame 200 to buffer seismic vibrations.

[0056] For example, such as Figure 4 As shown, the buffer pad 130 can be installed entirely around the glass layer 110, such as... Figure 4As shown in (a), it can also be installed as a whole around the glass layer 110, such as... Figure 4 Similar to (b) in the above, below, left and right frames of the glass layer 110, the rest can be installed on the packaging of the announcement, or on the edge of the glass layer 110, or on the glass layer 110.

[0057] The buffer pad 130 can be made of polyurethane, silicone, synthetic resin, rubber, etc., to buffer vibration. When it is attached to the glass layer 110, it is inserted into the frame groove 210 to buffer the vibration transmitted from the frame groove 210 to the glass layer 110.

[0058] The cushioning pad 130 may include a pad body 131, a grooved cushioning portion 133, and a side edge cushioning portion 135.

[0059] The encapsulation 131 is located around the glass layer 110 and can buffer the seismic vibrations of the glass layer 110 transmitted vertically by the glass frame 200.

[0060] The packaging body 131 can be square, and the packaging body 131 has a long length along the length direction of the frame groove 210, which can protect the edge of the glass layer 110.

[0061] Air flows into the center of the packaging body 131, and the middle section 131a, which is used to buffer the air, can penetrate along the length of the packaging body 131.

[0062] Among them, the middle part 131a reduces the rigidity of the package 131 and improves the vibration buffering. At the same time, when a relatively large vibration occurs, it allows the glass layer 110 in the glass frame 200 to vibrate, so that the glass layer 110 is pressed by the glass frame 200. This prevents the vibration transmitted by the glass frame 200 from being completely transmitted from the glass layer 110 to the glass layer 110, thereby preventing damage to the glass layer 110.

[0063] The groove buffer 133 is elastically deformed by the glass layer 110 inside the frame groove 210, which minimizes the gap between the frame groove 210 and the glass layer 110. This prevents the glass layer 110 from being easily shaken by small external forces such as wind in the glass frame 200.

[0064] The groove buffer portion 133 can be formed by protruding from the package body 131 into the depth direction of the frame groove 210, and its length is greater than the length of the package body 131. When the glass layer 110 is inserted into the frame groove 210, the groove buffer portion 133 elastically deforms, which can make up the gap between the frame groove 210 and the glass layer 110, and prevent the glass layer 110 from shaking in the frame 200 due to relatively small external forces such as wind.

[0065] For example, if the width of the frame groove 210 is greater than the thickness of the glass layer 110, the glass layer 110 is also prone to shaking under external forces such as a light breeze, and there is a possibility of damage. Therefore, the groove buffer part 133 can also perform the function of filling the gap between the frame groove 210 and the glass layer 110.

[0066] Furthermore, if the glass layer 110 in the frame groove 210 moves to one side, the glass layer 110 in the glass frame 200 will not be moved. The shape restoration force of the elastically deformed groove buffer 133 will keep the glass layer 110 in the frame groove 210 in a state of not being moved and in contact with each other, thereby reducing the impact of the glass layer 110 colliding with the frame groove 210 when returning.

[0067] The groove buffer portion 133 can extend into the frame groove 210 on both sides of the width direction of the package body 131. The groove buffer portion 133 can be attached only to a part of the side of the package body 131 through the partial cut groove portion 133a on the package body 131, while the remaining part located on the frame groove 210 can be separated from the package body 131 so that it can easily undergo elastic deformation when pressure is applied.

[0068] The groove buffer section 133 is a portion separated from the package 131. Therefore, while performing its function of supporting the glass layer 110 within the frame groove 210, especially in the event of a relatively large earthquake, the package 131 can flow within the groove buffer section 133. Thus, the glass layer 110 supported by the package 131 moves towards the frame 200 via its own weight, passing through position 110 in the direction of gravity, supported by the buffer section 133. This transfer prevents damage to the glass layer 110.

[0069] The edge buffer 135 extends from the packaging body 131 to the part where the edge portion 211 of the frame groove 210 is located. When an earthquake occurs, the glass layer 110 in the glass frame 200 will shake due to the vibration, preventing the edge portion 211 of the frame groove 210 from being damaged by collision.

[0070] The frame buffer portion 135 is formed between the frame portion 211 of the frame groove 210 and the glass layer 110, and has a longer protrusion than the frame portion 211. Therefore, the frame portion 211 can be forcibly deformed into a pleated form and inserted between the frame groove 210 and the frame portion 211 by applying pressure from above.

[0071] Among them, the edge buffer portion 135 has a longer length than the edge portion 211 on both sides in the width direction of the package body 131, and is located between the opposite edge portion 211 of each edge buffer portion 135 and the surface of the glass layer 110, which can prevent the edge portion 211 on both sides from colliding with the glass layer 110.

[0072] The frame buffer portion 135 is like a zigzag fold, forcibly inserting a fold between the frame portion 211 and the glass layer 110. Therefore, while preventing the glass layer 110 and the frame portion 211 from colliding, when a seismic vibration greater than the elasticity of the buffer pad occurs on the buffer pad 130, the glass layer 110 on the glass frame 200 can at least maintain its relative position by the load, thereby transmitting the vibration of the glass layer 200 to the glass 110.

[0073] The edge buffer portion 135 has an edge airtight portion 135a at its end that is wider than the gap between the glass layer 110 and the edge portion 211. When the edge buffer portion 135 is twisted between the glass layer 110 and the edge portion 211, the edge airtight portion 135a will elastically deform and seal the outside of the glass layer 110 and the edge portion 211 in an unrestrained manner, thus preventing the glass layer 110 from flowing into the confidential material.

[0074] Of course, the frame buffer 135 can be elastically deformed between the glass layer 110 and the frame 211, and then an airtight material 230 such as silicon can be sprayed on the upper part to prevent the frame buffer 135 sandwiched between the glass layer 110 and the frame 211 from easily detaching from the glass layer 110 and the frame 211.

[0075] Explain the roles and effects of the above components.

[0076] According to an embodiment of the present invention, the multilayer glass 100 with improved shock resistance by means of a buffer pad is a glass layer 110 formed by placing multiple glass plates 111 side by side and setting rods 113 or rod seals 115 along the perimeter of the glass plates 111 between the multiple glass plates 111.

[0077] Around the glass layer 110, in order to protect the perimeter of the glass layer 110, a glass frame 200 for fixing the glass layer 110 is installed on the perimeter of the glass layer 110, and a frame groove 210 for inserting into the glass layer 110 is formed on the inner perimeter of the glass frame 200.

[0078] A buffer pad 130 is provided between the glass layer 110 and the glass frame 200 to buffer seismic vibrations. The buffer pad 130 can be provided around the entire glass layer 110, or at each corner of the glass layer 110, or at the bottom edge of the glass layer 110, with the remaining edges provided on the glass frame 200.

[0079] The cushioning packaging 130 refers to the packaging body 131 being inserted into the frame groove 210 around the glass layer 110 using adhesives such as adhesives or tapes. On both sides of the packaging body 131 in the width direction, a recessed cushioning part 133 is formed, which is longer than the length of the packaging body 131 in the depth direction of the frame groove 210.

[0080] When the glass layer 110 is inserted into the frame groove 210, the groove buffer part 133 elastically deforms and fits tightly against the side of the frame groove 210, filling the gap between the frame groove 210 and the glass layer 110, which can prevent the glass layer 110 in the frame groove 210 from shaking.

[0081] The groove buffer 133 is first attached to the packaging body 131. When the ball is hit, the groove buffer 133 is located on the side of the packaging body 131, and is assembled on the packaging body 131 in a state where the cut groove 133a is separated from the upper part of the packaging body 131.

[0082] In the opposite direction to the direction in which the groove buffer portion 133 is formed in the package 131, the edge portion 211 of the frame groove 210 and the edge buffer portion 135 that prevents the glass layer body 110 from contacting each other are formed on both sides of the width direction of the package 131.

[0083] When the edge buffer portion 135 protruding from the packaging body 131 is inserted into the glass layer body 110 in the edge groove, it forms a length that is exposed from the edge portion 211. The edge buffer portion 135 elastically deforms and folds, and is forcibly inserted between the edge portion 211 and the glass layer body 110.

[0084] The edge of the frame portion 211 is formed into a frame security portion 135a. The outer side of the frame portion 211 and the glass layer 110 is restrained. The frame security portion 135a can secure the frame groove 210. The upper part of the frame security portion 135a is coated with a security material 230 to prevent the frame security portion 135a from detaching.

[0085] According to the embodiment of the present invention with the above composition, the laminated glass 100 with improved seismic resistance by means of a buffer pad can, in the event of an earthquake, isolate minor vibrations through the overall elastic force of the buffer pad 130, preventing them from being transmitted to the glass layer 110 and thus preventing damage to the glass layer 110.

[0086] Furthermore, if the vibration intensity increases further, the elastic body undergoes elastic deformation through the hollow part 131a of the elastic body to buffer the vibration. The vibration generated on the side can prevent the groove buffer part 133 from buffering during elastic deformation, which would cause the frame groove 210 to collide with the glass layer 110 or transmit relatively strong vibrations, thereby transmitting them to the glass layer 110 and preventing damage to the glass layer 110.

[0087] At this time, the elastomer and the groove buffer 133 have different thicknesses and sizes, and different elastic deformation degrees, which can effectively buffer vibrations of various sizes and prevent damage to the glass layer 110.

[0088] Even when the elastic force of the cushioning pad 130 generates a vibration greater than the magnitude that can be damped, the elastomer and the grooved buffer portion 133 are only partially formed by the notched groove portion 133a. Therefore, when the glass layer 110 is under load, the grooved buffer portion 133 can only move the glass frame 200 relatively differently to dampen the vibration.

[0089] Of course, even if the glass layer 110 in the frame groove 210 is biased to one side, the two remain in contact due to the elastic deformation of the groove buffer 133 unfolding or elastic deformation folding, thus preventing impact damage caused when the glass layer 110 is completely separated and re-contacted.

[0090] Furthermore, when vibration occurs, a pleated edge buffer 135 is inserted between the edge 211 of the glass layer 110 and the frame groove 210, so that even if the glass layer 110 and the glass frame 200 take different actions to prevent vibration, the glass layer 110 can be prevented from colliding and being damaged by the edge 211 of the glass frame 200.

[0091] The edge buffer portion 135 is located between the edge portion 211 and the glass layer 110, and is inserted in an elastic deformation form as if it were a pleat. Therefore, as the edge buffer portion 135 deforms, the edge portion 211 and the glass layer 110 elastically deform, which can improve the contact between the two and improve the dustproof performance.

[0092] For example, if the glass layer 110 moves to one side of the frame groove 210, the side frame buffer 135 located on one side will be compressed, while the side frame buffer 135 in the opposite direction with the gap widening will unfold under elastic deformation folding. Therefore, the two can continue to maintain contact, buffering vibration, thereby preventing material contact impact from damaging the glass layer 110 under complete isolation.

[0093] Therefore, according to an embodiment of the present invention, the seismic resistance of the laminated glass 100 is improved by using a buffer pad. A buffer pad 130 is provided between the glass frame 200 and the glass laminate 110. The glass frame 200 buffers and eliminates the seismic vibrations transmitted to the glass laminate 110, thereby improving the seismic resistance of the glass laminate 110.

[0094] Furthermore, by forming a hollow portion 131a on the encapsulation body 131, the glass layer 110 can flow on the glass frame 200. Even if a relatively large vibration occurs, only the glass frame 200 will vibrate. The glass layer 110 can be positioned under load by relative movement, thereby improving shock resistance.

[0095] In addition, in the buffer pad 130 of the present invention, since the groove buffer portion 133 is composed of a cut groove portion 133a, when a relatively large earthquake occurs, the glass layer 110 maintains its position by load, and only the glass frame 200 vibrates, thereby improving the earthquake resistance.

[0096] In addition, the present invention forms a frame buffer portion 135 in the buffer pad 130. The frame buffer portion 135 is inserted between the frame portion 211 of the glass frame (200) and the glass layer 110. Therefore, according to the vibration of the earthquake, not only can the damage caused by the collision between the frame of the glass frame 200 and the glass layer 110 be prevented, but also the vibration of the glass layer 110 as a whole can be achieved through the relative movement between the glass frame 200 and the glass layer 110, thereby preventing damage.

[0097] The embodiments of the present invention have been described above, but the scope of the present invention is not limited thereto, and includes all changes and modifications in the technical field to which the present invention pertains that are easily altered by a person with ordinary knowledge and are considered to be of equal scope.
