Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to a disconnected glass curtain wall closing structure. Background Art

[0002] When designing a glass curtain wall, the focus is often on the structural joints of the large surface, often overlooking the construction of the lower joint at ground level. The common practice for this joint is to fill the beams with rock wool and seal the exterior with galvanized iron sheets. This approach fails to create a fully sealed design between the glass and the main structure, resulting in various water seepage channels. In actual construction, it is also difficult to properly address this structural joint. Firstly, insufficient or missing rock wool plugging often occurs, resulting in cavities under the beams. Secondly, the connection between the external galvanized iron sheets, the beams, and the structure is not properly secured, often resulting in gaps or discontinuous application of glue. This makes it even more difficult to achieve a tight seal at the joints between the iron sheets. Furthermore, in some projects, the lower joint of the curtain wall is not properly constructed to connect with the main structure. After the glass curtain wall is installed, the lower cavity is directly filled by the exterior landscaping contractor. Because the curtain wall lower joint is constructed haphazardly and without adequate consideration for waterproofing and insulation, rainwater often leaks into the interior, making it difficult to repair and resulting in a poor user experience for the owners.

[0003] Chinese patent document CN201922182165.6 discloses a "lower closing connection structure for the first-floor glass curtain wall". A protective cover plate with an "L"-shaped cross-section is used below the first-floor glass curtain wall. The protective cover plate includes a vertical portion and a horizontal portion fixed to the lower end of the vertical portion, wherein the upper side wall of the vertical portion is horizontally provided with a first connector fixedly connected to the crossbeam, and an accommodating gap is formed between the upper end face of the first connector and the lower end face of the first-floor glass curtain wall, and a sealant and a foam rod are provided in the accommodating gap; one end of the horizontal portion is provided with a second connector fixedly connected to the wall, and a thermal insulation rock wool body is provided in the cavity formed by the protective cover plate and the wall surface. However, the protective structure related to this patent is relatively simple and cannot achieve the corresponding waterproof and heat-insulating effects. Summary of the Invention

[0004] The present invention mainly solves the technical problem of poor waterproof and heat-insulating effect at the bottom joint of the original glass curtain wall, and provides a disconnected glass curtain wall joint structure. An indoor alumina plate connected to the main structure is installed on the indoor side of the glass curtain wall, a micro-expansion waterproof mortar layer is provided between the indoor alumina plate and the inner side of the tongue outer alumina plate, and heat-insulating cotton is provided on the outer side of the outdoor alumina plate. By providing three layers of protection including the aluminum oxide plate, the micro-expansion waterproof mortar layer and the heat-insulating cotton, water vapor is fully isolated to prevent external water vapor from invading the indoor space.

[0005] A further object of the present invention is to provide a bracket below the tempered insulating glass, wherein one side of the bracket plate is connected to the sub-frame by bolts and nuts, the sub-frame is connected to the metal frame, the metal frame beams are spliced ​​with the columns, and the embedded parts can support the entire glass curtain wall through the column sleeves, thereby increasing the stability of the glass curtain wall;

[0006] A further object of the present invention is that the metal frame, the sub-frame and the bracket cooperate to support the entire glass curtain wall, thereby increasing the stability of the glass curtain wall.

[0007] The above-mentioned technical problems are primarily solved by the following technical solution: The present invention comprises a waterproof layer and tempered insulating glass. The waterproof layer includes a micro-expanding waterproof mortar layer, one side of which is connected to the interior of the room and the other side is connected to the insulation layer. The waterproof and insulation layers are installed below the tempered insulating glass. The waterproof and insulation layers are installed at the lower joint below the glass curtain wall composed of tempered insulating glass. The micro-expanding waterproof mortar layer effectively prevents moisture from intruding into the room through the lower joint of the glass curtain wall, while the insulation layer also reduces excessive heat loss from the room through the lower joint.

[0008] Preferably, embedded components are provided beneath the micro-expansion waterproof mortar layer, and insulation wool is positioned in the center of the insulation layer. An outdoor aluminum plate is installed on the side where the insulation layer connects to the waterproof layer, and a fluorocarbon-sprayed aluminum veneer is installed on the side where the insulation layer connects to the outside. The central portion of the insulation layer is filled with a large amount of insulation wool to minimize indoor heat loss through the lower edge of the glass curtain wall. The surface where the insulation wool connects to the outside is wrapped with a fluorocarbon-sprayed aluminum veneer. This fluorocarbon-sprayed aluminum veneer provides a relatively sturdy shell for the insulation wool within the insulation layer, resisting environmental corrosion and extending its service life. An outdoor aluminum plate is also installed where the insulation wool connects to the interior to reduce indoor corrosion.

[0009] Preferably, the waterproof layer comprises an indoor alumina plate and a micro-expansion waterproof mortar layer, disposed between the indoor and outdoor alumina plates. Encased within the indoor and outdoor alumina plates, the micro-expansion waterproof mortar layer provides strong waterproofing without significant expansion, achieving the combined advantages of enhanced waterproofing and reduced space usage.

[0010] Preferably, the embedded components are positioned beneath the micro-expansion waterproof mortar layer. They are provided with column sleeves that connect to the columns, and the columns are provided with metal frame beams. The embedded components serve as the foundation of the entire glass curtain wall and are embedded in the foundation prior to installation. The embedded components, through the column sleeves, support the entire glass curtain wall.

[0011] Preferably, a subframe is provided below the tempered insulating glass, and silicone structural adhesive is applied at the connection between the two. Furthermore, glass silicone weathering sealant is applied at the connection between the tempered insulating glass and the fluorocarbon-sprayed aluminum veneer. The silicone structural adhesive secures the tempered insulating glass to the subframe, tightly connecting the two together. The glass silicone weathering sealant secures the lower end of the tempered insulating glass to the upper surface of the fluorocarbon-sprayed aluminum veneer. The glass silicone weathering sealant provides a sealing effect, reduces the intrusion of external moisture into the glass curtain wall, and thus extends the service life of the glass curtain wall.

[0012] Preferably, a metal frame is provided at the upper end of the micro-expansion waterproof mortar layer, with a sub-frame provided on one side of the metal frame. The metal frame and the side of the sub-frame are connected by corresponding retaining holes, and corresponding retaining holes are provided at the bottom of the sub-frame and the upper end of the fluorocarbon-sprayed aluminum veneer. The metal frame is positioned above the micro-expansion waterproof mortar layer. The top of the metal frame supports the entire inner frame structure of the glass curtain wall through column inserts. The side of the metal frame is connected to the sub-frame via bolts and nuts. The side is supported by brackets connected to the sub-frame to securely support the tempered insulating glass.

[0013] Preferably, a bracket is provided below the tempered insulating glass. The bracket includes a bottom edge with longitudinal support plates on either side of the bottom edge, one of which is connected to the side of the sub-frame, and the other is connected to the tempered insulating glass. A bracket is provided below the tempered insulating glass to support the tempered insulating glass curtain wall above. One side of the support plates is connected to one side of the tempered insulating glass curtain wall to support and stabilize the entire glass curtain wall, while the other side is connected to the sub-frame via bolts and nuts. The sub-frame and bracket cooperate to support the entire glass curtain wall, thereby increasing its stability.

[0014] Preferably, the fluorocarbon sprayed aluminum veneer is in a concave shape to wrap around the thermal insulation cotton, and one side of the fluorocarbon sprayed aluminum veneer is connected to the metal frame crossbeam through an L-shaped connector, and the other side is connected to the foundation through an L-shaped connector. The connection on one side connected to the foundation is provided with an aluminum plate sealant. The fluorocarbon sprayed aluminum veneer on the outside of the thermal insulation cotton is in a concave shape as a whole to include the thermal insulation cotton, so as to reduce the erosion of the thermal insulation cotton by the external environment. Both sides of the fluorocarbon sprayed aluminum veneer are connected to the corresponding structure on the glass curtain wall through L-shaped fixings. After the fluorocarbon sprayed aluminum veneer is connected to the main structure of the glass curtain wall through the L-shaped fixings, it is fixed with expansion bolts through the corresponding holes on the fluorocarbon sprayed aluminum veneer and the L-shaped fixings. After that, it is also necessary to apply aluminum plate sealant on the fixings to protect the connection equipment and reduce the erosion of the connecting parts by external air and moisture.

[0015] Preferably, the embedded components include a horizontal beam and a vertical beam. The horizontal beam is disposed within the foundation beneath the micro-expansion waterproof mortar layer, and the vertical beam is mounted perpendicularly to the horizontal beam and extends into the foundation. The two vertical beams of the embedded components are vertically distributed on the horizontal beam and extend into the foundation, allowing the embedded components to be tightly fixed within the foundation. This further ensures sufficient support and structural strength for the entire glass curtain wall when installed on the embedded components.

[0016] The beneficial effects of the present invention are: the structural waterproof system involved in this patent is clear, the process is simple, the anti-leakage safety is high, and the thermal insulation effect is obvious. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: The disconnected glass curtain wall closing structure of this embodiment is as follows: Figure 1As shown, the structure comprises an insulation layer and a waterproof layer. The insulation layer is provided with insulation wool 9. The surface where the insulation wool connects to the outside world is wrapped with a fluorocarbon-sprayed aluminum veneer 7. The surface where the insulation wool connects to the interior is wrapped with an outdoor alumina plate 8. The insulation layer is connected to the waterproof layer. The waterproof layer comprises a micro-expanding waterproof mortar layer 6 and an indoor alumina plate 15. The micro-expanding waterproof mortar layer 6 is connected to the outdoor alumina plate 8 on one side and to the indoor alumina plate 15 on the other side. An embedded component 16 is provided below the waterproof layer. The embedded component 16 comprises a horizontal beam and two vertical beams perpendicularly connected to the horizontal beam. The entire embedded component 16 is set in the foundation, and the columns 13 are connected to the embedded component via column inserts 14. The metal frame crossbeam 2.1 is spliced ​​with the column. The metal frame crossbeam 2.1 is made of aluminum alloy. The tempered insulating glass 1 is bonded to the sub-frame 3 by silicone structural adhesive 4 to form a sash-like structure. The whole is installed on the column and the metal frame crossbeam 2.1 by bolts to form a basic glass curtain wall frame structure.

[0024] The gap between the metal frame beam 2.1 and the main structure 12 is sealed by the following three structures. First, the indoor side aluminum plate 15 of the indoor part is installed. The upper side of the aluminum plate is constructed with screws and angle brackets and sealed with glue. The lower side is connected to the main structure and glued to form the first waterproof barrier between the indoor and outdoor areas. The micro-expansion waterproof mortar layer 6 is filled between the metal frame beam 2.1 and the main structure. The filling is carried out from the outdoor side and filled to the inner wall of the indoor side aluminum plate. The micro-expansion waterproof mortar layer 6 is filled to the outer edge of the main structure. The whole needs to be dense to form the second waterproof barrier between the indoor and outdoor areas. The outdoor side aluminum plate 8 is installed. The upper end is constructed with the metal frame beam 2.1 and glued to it, and the lower end is connected to the side of the main structure and glued. The entire exterior of the outdoor side aluminum plate 8 is painted with waterproof paint, and extends downward to the main structure and upward to the metal frame beam 2.1. Fluorocarbon-coated aluminum veneer panels 7 are installed outside the anodized aluminum panels 8 on the exterior side, and insulation wadding 9 is placed inside. This insulation wadding effectively isolates the temperature difference between indoors and outdoors, achieving the insulation function of the glass curtain wall's lower end. The upper end of the fluorocarbon-coated aluminum veneer panels 7 is connected to the metal frame crossbeam 2.1, and a weather-resistant silicone sealant 5 is applied to the lower end of the tempered insulating glass. The lower end is connected to the main structure with expansion bolts 10, and aluminum plate sealant 11 is applied between the main structure and the panel, forming a third waterproof barrier between the interior and exterior, ultimately completing the glass curtain wall's lower end structure.

[0025] like Figure 2As shown, the sub-frame 3 is made of material, and the side is connected to the side of the metal frame 2. The sub-frame 3 is L-shaped as a whole. The lower side of the sub-frame 3 is buckled on the lower side of the upper end of the concave fluorocarbon sprayed aluminum single plate 7. Corresponding holes are provided at the connecting surface of the two, and the sub-frame 3 and the fluorocarbon sprayed aluminum single plate 7 are connected by a connecting piece. The right side of the sub-frame 3 is fixed to the tempered insulating glass 1 by silicone structural adhesive, and the left side of the sub-frame 3 is connected to the metal frame 2 with corresponding holes.

[0026] like Figure 3 As shown, a square metal frame 2 is mounted above the micro-expanding waterproof mortar layer 6. The top of the metal frame 2, near the tempered insulating glass 1, extends forward, supporting the innermost layer of tempered insulating glass 1. Two holes are provided on the upper side of the metal frame 2, corresponding to the sub-frame 3. Screws are inserted into the corresponding holes on the undersides of the metal frame 2 and the sub-frame 3 to secure them. Bolts and nuts are inserted into the corresponding holes on the undersides of the metal frame 2 and the sub-frame 3 to secure them. The bottom of the metal frame 2 is connected to the corresponding holes on the top of the micro-expanding waterproof mortar layer 6. Fixing balls and fixings are installed on the sides of the corresponding holes on the bottom of the metal frame 2 and the top of the micro-expanding waterproof mortar layer 6.

[0027] like Figure 4 As shown, the micro-expansion waterproof mortar layer 6 is arranged above the embedded part 16. The embedded part 16 includes a horizontal beam and a longitudinal beam. One side of the horizontal beam is connected to the bottom layer of the micro-expansion waterproof mortar layer 6, and the other side of the horizontal beam is buried in the indoor foundation. The horizontal beam buried in the foundation side is connected to two vertical beams, and the vertical beams go deep into the foundation. The two longitudinal beams deep into the foundation can fully fasten the embedded part 16 in the foundation. The vertical beams deeply buried in the foundation provide sufficient supporting strength for the entire embedded part 16. The embedded part 16 is connected and fixed to the tempered insulating glass 1 through the column 13 and the column core 14.
