Description

Technical Field

[0001] The present application relates to the technical field of hollow glass, and in particular to a hidden edge hollow glass and a glass curtain wall. Background Art

[0002] Insulating glass is a new type of building material that is beautiful and practical. It has the advantages of good heat insulation, sound insulation, and can reduce the weight of the building. Insulating glass is usually a glass product that uses two or more pieces of glass to be effectively supported and separated by a spacer containing a desiccant, and uses a high-strength and high-airtightness composite adhesive to bond and seal the perimeter, so that a dry gas space is formed between the glass layers.

[0003] In order to ensure the use requirements of air tightness and bonding strength, the current insulating glass is surrounded by spacers and sealants, so there will be a wide black edge around the glass. In some buildings with strong requirements for transparency, such as point-type glass curtain walls, rib-supported glass curtain walls, and opposite-side support system glass curtain walls, this black edge of the insulating glass will seriously affect the transparency of the building's facade. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a hidden-edge hollow glass and a glass curtain wall. The glass can be provided with a special edge sealing structure so that the glass has an invisible edge effect, which can improve the transparency of the building and meet the use requirements of the hollow glass.

[0005] In the first aspect, an embodiment of the present application provides a hidden-edge hollow glass, which includes two oppositely arranged glass plates and a hollow layer located between the two glass plates, an edge sealing plate is arranged between partial edges of the two glass plates, at least one of the glass plates is a staggered glass plate, and the edge end surface of the edge sealing plate of the staggered glass plate is recessed adjacent to the hollow layer to form a built-in space, the edge sealing plate is arranged in the built-in space corresponding to one end of the staggered glass plate, and a sealing adhesive structure for sealing the hollow layer is respectively arranged between the two glass plates and the edge sealing plate.

[0006] In the above implementation process, a new edge structure of the invisible edge insulating glass is formed by using an edge sealing plate and a sealing bonding structure, wherein the edge sealing plate plays a supporting role, and a smaller thickness edge sealing plate can support the load on the glass surface, and the sealing bonding structure plays the role of bonding the edge sealing plate to the glass plate and sealing the edge of the invisible edge insulating glass. Through the above-mentioned new edge structure, not only can the edge of the glass be transparent without black edges due to the absence of a spacer, breaking through the black edge structure of the traditional insulating glass on all sides, and having a better appearance effect, but also the glass can be provided with a special edge sealing structure, so that the glass has the effect of invisible edges, which can improve the transparent effect of the building and meet the use requirements of the insulating glass at the same time. Specifically, the edge sealing plate is arranged in the built-in space of the staggered glass plate, thereby forming the effect that the edge sealing plate is embedded in the staggered glass plate, and the contact area between the edge sealing plate and the staggered glass plate is large, which can meet the requirements of the insulating glass edge position for support strength and bonding strength, and the edge sealing plate is embedded, which can play a protective role on the edge sealing plate, which is convenient for the transportation and use of the insulating glass.

[0007] Therefore, the edge structure of the invisible edge insulating glass in the embodiment of the present application can be very narrow, with the effect of invisible edges, and is suitable for the construction of glass curtain walls such as point-type glass curtain walls, rib-supported glass curtain walls, and opposite-side supported system glass curtain walls.

[0008] In a possible implementation, one of the glass plates is the staggered glass plate, and the other glass plate is a conventional glass plate. One end of the edge sealing plate corresponding to the staggered glass plate is arranged in the built-in space, and the other end of the edge sealing plate is arranged outside the edge of the conventional glass plate.

[0009] In the above implementation process, the staggered glass plates and the conventional glass plates are arranged in coordination, and the formed hidden edge hollow glass structure is simple and easy to implement.

[0010] In a possible implementation, one end of the edge sealing plate corresponding to the conventional glass plate is lower than the surface of the conventional glass plate away from the hollow layer, and the edge of the hidden-edge hollow glass close to the conventional glass plate has a step-back.

[0011] In the above implementation process, the edge position of the invisible edge insulating glass close to the conventional glass plate has a step-back. After the edge is glued, the glue at the step-back position can cover the new edge structure of the invisible edge insulating glass, further improving the effect of the invisible edge.

[0012] In a possible implementation, both of the two glass plates are the staggered glass plates, and both ends of the edge sealing plate are respectively disposed in the built-in spaces of the two staggered glass plates.

[0013] In the above implementation process, the two staggered glass panels can form a structurally symmetrical hidden-edge insulating glass, and the supporting strength and bonding strength at the edge position are high.

[0014] In a possible implementation, the offset glass plates include a first glass and a second glass that are relatively arranged, and the first glass is adjacent to the hollow layer. The edge of the edge sealing plate of the first glass is recessed relative to the corresponding edge of the second glass to form the built-in space, and the two ends of the edge sealing plate are respectively located on the outside of the edges of the two first glasses, and the sealing bonding structure is arranged between the edge sealing plate and the edge end face of the first glass and the surface of the second glass adjacent to the hollow layer.

[0015] In the above implementation process, the edges of the first glass and the second glass are staggered (the edge of the first glass is recessed relative to the corresponding edge of the second glass), so that a built-in space is formed on the edge end faces of the staggered glass plates, and the edge sealing plate is embedded between the edges of the two second glasses. The two ends of the edge sealing plate are bonded to the surfaces of the two second glasses through a sealing adhesive structure, and the inner surface of the edge sealing plate is bonded to the edge end faces of the two first glasses through a sealing adhesive structure, so as to form a new type of extremely narrow edge structure of hidden-edge insulating glass.

[0016] In a possible implementation, the offset glass plate further includes a laminated film, and the laminated film is laminated between the first glass and the second glass.

[0017] In the above implementation process, the edges of the first glass and the second glass are misaligned, and the first glass and the second glass are bonded together by a laminated sheet to form a laminated glass sheet, thereby easily forming a built-in space.

[0018] In a possible implementation, the outer surface of the edge sealing plate away from the hollow layer is flush with the outermost end surface of the corresponding edge of the offset glass plate;

[0019] Alternatively, the outer surface of the edge sealing plate away from the hollow layer is recessed relative to the outermost end surface of the corresponding edge of the offset glass plate.

[0020] In the above implementation process, the edge sealing board is flush with or relatively concave to the outermost end surface of the offset glass plate, so that the edge sealing board can be completely embedded in the glass sheet, thereby protecting the edge sealing board through the offset glass plate.

[0021] In a possible implementation, the edge of the offset glass plate where the edge sealing plate is provided is chamfered at a position away from the hollow layer.

[0022] In the above implementation process, a chamfer is set at the position corresponding to the new edge structure of the hidden edge insulating glass. After the edge of the hidden edge insulating glass is glued and the hidden edge insulating glass is installed in place, the glue at the chamfer position can cover the new edge structure of the hidden edge insulating glass, further improving the effect of the invisible edge, and even making the hidden edge insulating glass achieve a visually completely hidden edge effect.

[0023] In a possible implementation, the surface of the offset glass plate away from the hollow layer is used as the projection surface, and the projections of the sealing adhesive structure and the edge sealing plate are both within the projection area of ​​the chamfer.

[0024] In the above implementation process, by controlling the chamfered area, the glue applied at the chamfered position can completely cover the new edge structure formed by the sealing bonding structure and the edge sealing board, thereby achieving a completely hidden edge effect.

[0025] In a possible implementation manner, the sealing bonding structure includes an adhesive layer for bonding the glass plate and the edge sealing plate.

[0026] In the above implementation process, the adhesive layer plays a structural bonding role, and the edge sealing plate is attached to the corresponding edge position of the glass plate through the adhesive layer.

[0027] In a possible implementation, the sealing adhesive structure further includes a sealing strip filled between the glass plate and the edge sealing plate, and the sealing strip is closer to the hollow layer than the adhesive layer.

[0028] In the above implementation process, the sealing structural adhesive plays a role in water vapor sealing. The sealing strip and the sealing structural adhesive can not only achieve two-way bonding between the edge sealing plate and the glass sheet, but also prevent water vapor and inert gas from entering and exiting the hollow layer, thereby improving the airtightness of the middle layer.

[0029] In a possible implementation, the edge sealing plates are respectively provided on two opposite sides of the glass plate;

[0030] And / or, the edge sealing plate is arranged along the entire or partial area of ​​one side edge of the glass plate.

[0031] In the above implementation process, edge sealing panels are set on the opposite sides of the invisible insulating glass. The edge sealing panels can be set along the entire edge or part of the edge area, which can be suitable for most application scenarios.

[0032] In a possible implementation, a spacer bar is provided between at least a portion of the edges of the two glass plates where the edge sealing plates are not provided, and the spacer bar and the glass plates are bonded together by a structural sealant to seal the hollow layer.

[0033] In the above implementation process, since the hidden edge insulating glass is provided with a new edge structure, the spacer bars are eliminated at the edge, and the molecular sieve with adsorption and drying function is also eliminated. In order to ensure the overall internal dryness and cleanliness of the hidden edge insulating glass, it is necessary to set spacer bars at other edge positions, that is, to set molecular sieves to exert the adsorption function.

[0034] In a second aspect, an embodiment of the present application provides a glass curtain wall, which includes at least two pieces of insulating glass, at least one of which is the hidden-edge insulating glass of the aforementioned embodiment, and the edges of adjacent insulating glasses are spliced ​​together.

[0035] In the above implementation process, the glass curtain wall composed of invisible edge hollow glass has the effect of invisible edge, which can improve the transparency of the building.

[0036] In a possible implementation, the adjacent insulating glasses are all the invisible-edge insulating glasses, and the invisible-edge insulating glasses are spliced ​​together at the edges of the edge sealing plates.

[0037] In a possible implementation, one of the glass plates of the hidden edge hollow glass is the staggered glass plate, and the other glass plate is a conventional glass plate; one end of the edge sealing plate corresponding to the staggered glass plate is arranged in the built-in space, and the other end of the edge sealing plate is arranged outside the edge of the conventional glass plate; one end of the edge sealing plate corresponding to the conventional glass plate is lower than the surface of the conventional glass plate away from the hollow layer; the hidden edge hollow glass has a step-back at the edge position close to the conventional glass plate, and the edge of the staggered glass plate where the edge sealing plate is arranged away from the hollow layer is chamfered; the adhesive at the adjacent splicing positions of the hollow glass covers the step-back and the chamfer to form a hidden edge effect.

[0038] In the above implementation process, adjacent insulating glass will be spliced ​​together with a special edge sealing structure with an invisible edge effect. The adhesive covers the chamfers and stepbacks of the invisible edge insulating glass, shielding the special edge sealing structure to form a hidden edge effect, thereby making the invisible edge effect at the splicing point good and improving the transparency of the building.

[0039] In a possible implementation, foam bars are provided at the joint positions of adjacent insulating glasses and are bonded together by adhesive.

[0040] In the above implementation process, the foam rod is combined with the adhesive to ensure that the formed glass curtain wall has high overall strength and good sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] First embodiment

[0061] Please see Figure 1-Figure 3 The present embodiment provides a hidden edge hollow glass 100, which includes two oppositely arranged glass plates and a hollow layer 120 located between the two glass plates, an edge sealing plate 140 is arranged between partial edges of the two glass plates, wherein at least one of the glass plates is a staggered glass plate 110, and the edge end surface of the staggered glass plate 110 where the edge sealing plate 140 is arranged is recessed adjacent to the hollow layer 120 to form a built-in space, and the edge sealing plate 140 is arranged in the built-in space corresponding to one end of the staggered glass plate 110, and a sealing adhesive structure 150 for sealing the hollow layer 120 is respectively arranged between the two glass plates and the edge sealing plate 140.

[0062] In the embodiments of the present application, the plane shape of the glass plate can be a quadrilateral, or a triangle, a polygon, or even an irregular shape. Correspondingly, the edge of the glass plate can be a straight line, or a curve, a broken line, or a combination of various line shapes. The present application does not impose any specific restrictions on this, and the specific selection can be made according to the actual situation. The shapes of the two glass plates can be the same or slightly different. The two glass plates are usually arranged relative to each other in the same plane so that the edge end faces of the combined hidden edge hollow glass 100 are flat, which is convenient for installation and splicing during use. The present application does not impose any specific restrictions on the shape of the edge sealing plate 140. From the perspective of its plane shape, the edge sealing plate 140 has two relatively arranged edges. These two edges serve as the two ends of the edge sealing plate 140 and are connected to the two glass plates in a one-to-one correspondence.

[0063] In the embodiment of the present application, one of the glass plates is a staggered glass plate 110, and the other glass plate is a conventional glass plate 180. One end of the edge sealing plate 140 corresponding to the staggered glass plate 110 is arranged in the built-in space, and the other end of the edge sealing plate 140 is arranged on the outside of the edge of the conventional glass plate 180.

[0064] In the embodiment of the present application, the surface of the glass plate is divided into an inner surface close to the hollow layer 120 and an opposite outer surface. From the edge end surface of the offset glass plate 110 where the edge sealing plate 140 is set, the position close to the inner surface is recessed relative to the position close to the outer surface, that is, the edge end surface is a step structure, and the step close to the inner surface is the built-in space. The present application does not impose any specific restrictions on the shape of the built-in space, which is usually matched with the shape of the corresponding end of the edge sealing plate 140, so that the ends of the edge sealing plate 140 can be respectively set in the built-in space corresponding to the offset glass plate 110. In this embodiment, the opposite ends of the edge sealing plate 140 are both straight lines, and the shapes of the corresponding built-in spaces are also straight lines.

[0065] In the embodiment of the present application, one end of the edge sealing plate 140 corresponding to the conventional glass plate 180 is lower than the surface of the conventional glass plate 180 away from the hollow layer 120 , and the edge of the hidden-edge insulating glass 100 close to the conventional glass plate 180 has a step-back.

[0066] In the embodiment of the present application, the edge sealing plate 140 and the sealing adhesive structure 150 together form a new edge structure. The edge of the invisible insulating glass 100 with the new edge structure is a special edge sealing 114, and the remaining edges can be designed as conventional black edges 115. From the edge end face of the invisible insulating glass 100 with the new edge structure, the edge sealing plate 140 is embedded in the overall structure through the stepped structure design of the edge end face of the staggered glass plate 110, and the width of the edge sealing plate 140 is less than the overall thickness of the invisible insulating glass 100, so that the invisible insulating glass 100 has the effect of invisible edges; at the same time, the embedded design of the edge sealing plate 140 can meet the requirements of the edge position of the invisible insulating glass 100 for support strength and bonding strength, and can protect the edge sealing plate 140 to meet the use requirements of insulating glass.

[0067] Please see Figure 2In some embodiments of the present application, the offset glass plate 110 includes a first glass 111 and a second glass 112 that are oppositely arranged, and the first glass 111 is adjacent to the hollow layer 120, and a laminated sheet 113 is stacked between the first glass 111 and the second glass 112, and the first glass 111 and the second glass 112 are bonded into one body by the laminated sheet 113, that is, a laminated glass plate; the edge of the first glass 111 provided with an edge sealing plate 140 is recessed relative to the corresponding edge of the second glass 112 to form a built-in space, and the two ends of the edge sealing plate 140 are respectively correspondingly located on the outside of the edges of the two first glasses 111 (the edge sealing plate 140 is located as a whole on the outside of the edges of the two first glasses 111), and a sealing adhesive structure 150 is provided between the edge sealing plate 140 and the edge end surface of the first glass 111 and the surface of the second glass 112 adjacent to the hollow layer 120. In this embodiment, the edge sealing plate 140 and the end surface of the first glass 111 and the inner surface of the second glass 112 are all flat direct contact surfaces, and the sealing bonding structure 150 located on the contact surface is a thin structure, which plays the role of structural bonding between the edge sealing plate 140 and the offset glass plate 110 and the peripheral sealing of the hidden edge insulating glass 100.

[0068] In other embodiments, the staggered glass plates 110 may also form built-in spaces in other ways. As one embodiment, the first glass 111 and the second glass 112 are an integrated glass structure, and the built-in space is cut at the edge of the whole staggered glass plate 110, or the staggered glass plate 110 with the built-in space is directly formed by a mold. As another embodiment, the first glass 111 and the second glass 112 are split glass structures, and they are bonded together by other means, such as hot melt bonding or other bonding methods.

[0069] In some embodiments of the present application, the edge sealing plate 140 is completely embedded in the overall structure, and from the edge end surface of the hidden edge insulating glass 100 provided with the edge sealing plate 140, the edge sealing plate 140 is flush with the second glass 112 or the edge sealing plate 140 is slightly recessed relative to the second glass 112. Specifically, the outer surface of the edge sealing plate 140 away from the hollow layer 120 is flush with the outermost end surface of the corresponding edge of the offset glass plate 110 (the end surface of the corresponding edge of the second glass 112); or, the outer surface of the edge sealing plate 140 away from the hollow layer 120 is recessed relative to the outermost end surface of the corresponding edge of the offset glass plate 110 (the end surface of the corresponding edge of the second glass 112), so as to form an effect that the edge sealing plate 140 is completely embedded in the hidden edge insulating glass 100. In some other embodiments of the present application, the edge sealing plate 140 can also be partially embedded in the overall structure. Seen from the edge end face of the hidden-edge insulating glass 100 provided with the edge sealing plate 140, the edge sealing plate 140 is slightly raised relative to the second glass 112. Specifically, the outer surface of the edge sealing plate 140 away from the hollow layer 120 is raised relative to the outermost end face of the corresponding edge of the staggered glass plate 110 (the end face of the corresponding edge of the second glass 112).

[0070] In some embodiments of the present application, the distance between the two glass plates (the thickness of the hollow layer 120 ) is 12 to 16 mm; and the thickness of the edge sealing plate 140 in the transverse direction is 1 to 3 mm.

[0071] In order to further improve the invisible edge effect, a chamfer 130 is provided at a position of the edge of the glass plate where the edge sealing plate 140 is provided, away from the hollow layer 120 .

[0072] As an embodiment, the sealing adhesive structure 150 includes an adhesive layer 151 for bonding the glass plate and the edge sealing plate 140 and a sealing strip 152 filled between the glass plate and the edge sealing plate 140. The sealing strip 152 is closer to the hollow layer 120 than the adhesive layer 151. In this embodiment, the edge end surface of the first glass 111 of the offset glass plate 110 is bonded to the edge sealing plate 140 through the sealing strip 152, and the other positions of the edge end surface of the second glass 112 and the position of the inner surface of the second glass 112 corresponding to the edge sealing plate 140 are bonded to the edge sealing plate 140 through the adhesive layer 151. The conventional glass plate 180 is also provided with an adhesive layer 151 and a sealing strip 152 between the conventional glass plate 180 and the edge sealing plate. In other embodiments of the present application, the sealing adhesive structure 150 can also directly use a material with sealing and bonding functions, or the distribution positions of the sealing strip 152 and the adhesive layer 151 can be adjusted in other ways.

[0073] In the embodiment of the present application, the adhesive forming the adhesive layer 151 plays an adhesive role and can usually pass water vapor. It can be made of at least one of silicone structural sealant, polyurethane sealant and polysulfide sealant, SGP film, UV glue or other structural adhesive layer 151. The sealing strip 152 is mainly used to prevent water vapor from passing through, and its material includes at least one of butyl glue, thermoplastic spacer sealant and other materials.

[0074] In the embodiments of the present application, in order to make the edge structure of the hidden edge insulating glass 100 as thin as possible, it is necessary to make the thickness of the sealing adhesive structure 150 as small as possible. In some embodiments of the present application, the width of the sealing adhesive structure 150 (the thickness of the sealing adhesive structure 150 on the outer side of the edge of the second glass 112) is 1 to 3 mm. The ultra-thin edge structure must meet various force requirements, as well as the sealing performance requirements of the insulating glass and various usage requirements. The new edge structure and material of the embodiments of the present application can meet various requirements such as bonding performance requirements, force requirements, thermal performance requirements, thermal expansion performance requirements, etc.

[0075] In some embodiments of the present application, the edge sealing plate 140 is made of a material with sufficient strength and compatible with the sealing bonding structure 150, such as stainless steel, titanium and titanium alloy, low thermal expansion coefficient alloy, aluminum, organic material (PP or PC) or composite material, etc. The edge sealing plate 140 can be made of a transparent material or a non-transparent material, and there is no limitation on this. Exemplarily, the edge sealing plate 140 is a stainless steel plate, an aluminum plate, a PP plate or a PC plate or a composite material.

[0076] In the embodiment of the present application, edge sealing plates 140 are respectively provided on the opposite side edges of the glass plate; the edge sealing plates 140 are provided along the entire or partial area of ​​one side edge of the glass plate. As an implementation mode, at least two edges of the invisible edge insulating glass 100 have no black edges, but a new edge structure is used to form a special edge sealing 114. The invisible edge insulating glass 100 can be designed with 4 edges as special edge sealing 114 (no black edges). In the present embodiment, the opposite side edges of the invisible edge insulating glass 100 are special edge sealing 114, and the opposite side edges of the glass plate are respectively provided with edge sealing plates 140. The edge sealing plates 140 on each side are provided along the entire area of ​​the side edge of the glass plate. Such invisible edge insulating glass 100 with two edges as special edge sealing 114 can be suitable for most application scenarios.

[0077] Please see Figure 3In some embodiments of the present application, other edges of the invisible-edge insulating glass 100 other than the special edge sealing 114 can be designed as conventional black edges 115, that is, a spacer bar 160 is arranged between at least part of the edges of the two glass plates where the edge sealing plate 140 is not arranged, and the spacer bar 160 and the glass plates are bonded together by structural sealant and the hollow layer 120 is sealed. In this embodiment, the other two opposite edges of the hidden edge insulating glass 100 are black edges 115, that is, the other two opposite edges of the glass plate are respectively provided with spacer strips 160, and the structural sealant includes sealant 171 and adhesive 172. Specifically, the other two opposite edges of the glass plate are flush (the edge end surfaces of the first glass 111 and the second glass 112 are flush), the spacer strip 160 is filled between the two glass plates, and the spacer strip 160 is located at the position adjacent to the opposite two sides of the glass plate, and the adhesive 172 in the groove of the spacer strip 160 is in contact with the glass plate, and the sealant 171 is applied to the outer side of the spacer strip 160, and the surface of the sealant 171 is flush with the corresponding side of the glass plate.

[0078] Since the present application uses spacer bars 160 only on the two side edges of the glass plate, and the other two side edges are supported and fixedly connected by a new edge structure, the glass plate has black edges 115 only on the two opposite sides, and the other two sides have special edge sealing 114 without black edges, so as to achieve the effect of edge hiding, improve the transparency and aesthetics of the edge-hidden insulating glass 100, and solve the problem that the existing insulating glass has black edges around it and the appearance effect is poor. In addition, the edge-hidden insulating glass 100 is compatible with all current energy-saving and environmentally friendly high-performance technologies, and realizes a high-performance edge-hidden insulating glass 100 product. The only two side black edges 115 of the edge-hidden insulating glass 100 can be hidden in the curtain wall components, thereby improving the overall transparency and aesthetics of the curtain wall to meet the expected effect of the building.

[0079] The invisible edge insulating glass 100 of the embodiment of the present application is particularly suitable for point-type glass curtain walls, rib-supported glass curtain walls, and opposite-side support system glass curtain walls. In this type of curtain wall, the common practice is to splice the black edges of the insulating glass with ordinary edge structures together. The black edges of the glass are spliced ​​into black glass seams, which appear as wide black lines on the exterior of the building. The embodiment of the present application uses invisible edge insulating glass 100 with a new edge structure. The opaque part of the joint of the invisible edge insulating glass 100 has only a width of the glue seam after gluing. The width of the opaque part is much smaller than the black seam of ordinary insulating glass, and the seam can be made of transparent or translucent adhesive to further weaken the appearance of the seam.
