Description

Technical Field

[0001] The invention relates to the technical field of building curtain walls, in particular to a combined unit system with a large cantilever horizontal sunshade. Background Art

[0002] As an important part of the external structure of modern buildings, the curtain wall has experienced a technical iteration from the traditional complete frame curtain wall to the independent unit curtain wall. As a modern building exterior wall system, the unit curtain wall system is decomposed into independent unit modules. Each module is processed and manufactured in the factory to ensure the processing quality, and the hanging and interface processing are carried out on site, which greatly improves the construction efficiency and quality and reduces the construction cost. The rise of this technical path is closely related to the process of building industrialization. Especially in high-rise buildings, commercial complexes and other projects, the unit curtain wall has the advantages of standardization, prefabrication and modular installation, which enables it to be quickly installed and gradually become the mainstream technical solution to adapt to the construction rhythm of high-rise buildings. The conventional unit curtain wall is divided into unit panels according to the floor and horizontal grid, that is, the transparent part and the interlayer design form a panel, which is hung and installed layer by layer from bottom to top during construction.

[0003] However, although conventional unitized curtain walls can reduce certain construction costs and risks compared to traditional frame curtain walls, their transportation, decoration and maintenance costs are still high. When the curtain wall is damaged due to extreme weather conditions or human factors, the damaged curtain wall unit needs to be dismantled and replaced as a whole, which is very expensive. In addition, conventional unitized curtain walls must also be installed from bottom to top and layer by layer during installation, which is very inconvenient for the construction process. At the same time, the glass curtain wall will allow too much solar radiation heat to enter the room, affecting indoor comfort and use functions. It can be seen that conventional unitized curtain walls have problems such as high transportation and decoration costs, difficult maintenance, poor shading effect, and difficulty in meeting the convenience requirements during building decoration. Therefore, it is urgent to develop a curtain wall combination unit system with horizontal sunshades, in which both inter-layer and non-inter-layer units are independent units.

Detailed implementation manners

[0077] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0078] As Figure 1 , Figure 2 and Figure 9 shown, an embodiment of the present invention provides a combined unit system with a large cantilever horizontal sunshade, including:

[0079] A plurality of interlayer units 1, the plurality of interlayer units 1 are connected by side columns 2, and each unit of the plurality of interlayer units 1 includes at least one interlayer plate 3, and the interlayer plates 3 are connected by middle columns 4;

[0080] A plurality of glass units 5 installed between the plurality of interlayer units 1 in the vertical direction, and each unit of the plurality of glass units 5 includes at least one glass plate 6;

[0081] A drainage structure 7 located at the junction of the plurality of interlayer units 1 and the plurality of glass units 5;

[0082] A ventilation device 8 is installed at the bottom of the plurality of interlayer units 1;

[0083] Among them, the plurality of interlayer units 1 are respectively hung on the main structure 9, and the plurality of glass units 5 are inserted between the plurality of interlayer units 1 by means of snap connection and glue injection connection.

[0084] In this embodiment, the curtain wall unit is modularly designed. Standardized components finely processed by the factory assembly line are assembled and spliced directly on the decoration site to achieve the efficient installation and function integration of the curtain wall. The interlayer unit supports horizontal splicing, adapts to the requirements of different building widths, and at the same time reserves space for equipment installation.

[0085] The interlayer plate 3 is the basic unit that constitutes the plurality of interlayer units 1. Each interlayer unit is formed by combining one or more interlayer plates 3. The plurality of interlayer plates 3 are supported by middle columns 4 to form a stable frame structure; the plurality of interlayer units 1 are vertically spliced by side columns 2 to form the horizontal division of the building facade. Compared with the side columns 2 between the plurality of interlayer units 1, there are no gaps after the interlayer plates 3 fixed by the middle columns 4 are combined. Therefore, only one middle column 4 is sufficient to play a supporting role. At the same time, the manufacturing materials used for the middle column 4 are also less, thereby reducing the construction cost and the manufacturing cost of the curtain wall unit.

[0086] The non-interlayer unit of the curtain wall unit is the glass unit. Each glass unit includes at least one glass plate 6. The plurality of glass units 5 are made of low-emissivity glass material and combined with broken bridge heat insulation profiles to reduce the temperature exchange between indoors and outdoors and improve the thermal performance of the curtain wall. At the same time, each glass unit supports independent disassembly, which is convenient for later maintenance or upgrade. The plurality of glass units 5 are installed between the plurality of interlayer units 1 on the upper and lower floors by means of snaps, and are inserted into the embedded channels of the vertical side frames of the interlayer units through metal snaps to achieve rapid positioning; on this basis, weather-resistant sealant is injected into the joints between the glass plates 6 and the profiles to form a double-layer protection of airtightness and watertightness.

[0087] The curtain wall unit is provided with waterproof and drainage measures on both the upper and lower cross beams. The main waterproof measures for the upper cross beam are as follows: Sealant is applied at the position where the water trough material of the upper cross beam of the interlayer unit contacts the cross beam, the joints of the butt joints of the cross beams are sealed with sealant and scraped flat, the waterproof rubber sheet is adhered to the joint at the outer butt joint position of the cross beam with sealant, and the positions around the waterproof rubber sheet are sealed with sealant. The main waterproof measures for the lower cross beam are as follows: Sealant is applied at the position where the water trough material of the lower cross beam of the interlayer unit contacts the cross beam, and the joints of the butt joints of the cross beams are sealed with sealant and scraped flat. The main drainage measures for the upper cross beam are as follows: Drainage is carried out to the outside through the drainage holes 31 of the drainage structure 7. The main drainage measures for the lower cross beam are as follows: Water is drained to the upper cross beam position of the lower layer unit through the drainage holes 31. The drainage structure 7 is generally an inclined structure arranged on the outer surface of the interlayer unit, which has an anti-backflow function and can guide rainwater to the outside of the column. At the same time, the structure is provided with anti-siphon hooks in the area close to the outside of the building to prevent rainwater from flowing back into the curtain wall unit due to external wind pressure.

[0088] The bottom of multiple interlayer units 1 is installed with an openable ventilation device 8, which can be designed as a ventilation opening that can adjust the ventilation volume through manual or electric control according to project requirements, and combined with the thermosiphon principle, natural convection is formed by using the temperature difference between indoors and outdoors to reduce air conditioning energy consumption. A stainless steel mesh needs to be set at the ventilation opening to achieve the purpose of preventing insects and dust. Select a suitable mesh density to ensure that the filtering efficiency for insects is ≥90% and balance the ventilation effect to prevent poor ventilation due to too dense mesh holes.

[0089] The upper and lower fulcrums of the multiple split interlayer units 1 are all hung on the main structure 9, and multiple glass units 5 are inserted into the multiple interlayer units, without the need to be connected to the main structure 9, without changing the force form on the main structure 9, and without increasing the cost of the main structure 9.

[0090] As Figure 1 and Figure 3 shown, in an optional embodiment of the present invention, the multiple interlayer units 1 include:

[0091] An interlayer unit main body 10 installed on the outer surface of the building main body;

[0092] A first connection structure 11 for hanging the interlayer unit main body 10 on the main structure 9.

[0093] In this embodiment, the interlayer unit main body 10 is a horizontal layered module of the curtain wall system, which is directly installed on the outer surface of the building main body through the first connection structure 11, and undertakes the functions of sunshade, protection, decoration and partial structural force. Its design needs to adopt standardized dimensions to facilitate factory prefabrication and on-site rapid installation. The main frame is usually composed of aluminum alloy profiles, and sunshade panels or decorative panels can be integrated on the surface to achieve the unity of function and aesthetics.

[0094] The first connection structure 11 is a hanging system between the interlayer unit main body 10 and the building main structure 9, which needs to bear the self-weight of the curtain wall, wind load and seismic action. Embedding needs to be carried out in advance in the concrete floor slab to increase the firmness of the connection between the first connection structure 11 and the building and the interlayer unit main body 10 and prevent position slip.

[0095] As Figure 2 and Figure 3 shown, in an optional embodiment of the present invention, the first connection structure 11 includes:

[0096] A unit upper hanging ear 44 fixedly installed on the side column 2 through the bolt 20;

[0097] A unit upper code piece 45 fixedly connected to the unit upper hanging ear 44 through the screw 17 and a buckle;

[0098] A pre-embedded part 46 fixedly connected to the unit upper code piece 45 through a pre-embedded bolt 63. The pre-embedded part 46 is installed in the concrete floor slab of the building, and the bottom of the pre-embedded part 46 is welded to the main structure 9;

[0099] A unit lower hanging ear 47 fixedly installed on the side column 2 through the bolt 20;

[0100] A unit body floor code 48 fixedly connected to the unit lower hanging ear 47 through the screw 17 and a buckle;

[0101] A unit lower code piece 49 fixedly connected to the unit body floor code 48 through the bolt 20. The top of the unit lower code piece 49 is welded to the main structure 9.

[0102] In this embodiment, the first connection structure 11 can be divided into an upper hanging component and a lower hanging component. Among them, the upper hanging component includes a unit upper hanging ear 44, a unit upper code piece 45, and a pre-embedded part 46; the lower hanging component includes a unit lower hanging ear 47, a unit body floor code 48, and a unit lower code piece 49.

[0103] The unit upper hanging ear 44 and the unit lower hanging ear 47 are made of aluminum alloy extrusion profiles with a thickness ≥6 mm, and the surface is anodized with a film thickness ≥15 μm; round holes are opened on both the unit upper hanging ear 44 and the unit lower hanging ear 47, and the bolt 20 passes through the round holes and is rigidly connected to the side column 2.

[0104] The unit upper code piece 45 and the unit upper hanging ear 44 form a composite connection through the screw 17 and a buckle. Among them, the screw realizes rigid fixation, and the buckle provides seismic buffering to avoid stress concentration caused by hard contact.

[0105] The embedded part 46 is embedded in the concrete floor slab, and its bottom is connected to the main structure 9 by full penetration groove welding. The weld grade is grade I, and the flaw detection pass rate is 100%; it is fixed to the ear plate of the upper unit fitting 45 through the embedded bolt 63 to prevent the main body 10 of the interlayer unit connected from moving.

[0106] The unit floor base 48 and the unit lower hanging ear 47 are double-connected by screws 17 and buckles. The buckle can be internally provided with a damping rubber pad to absorb vibration energy, and adjustable gaskets can be set at the bottom to adjust the verticality of the curtain wall unit.

[0107] The top end of the lower unit fitting 49 is connected to the main structure 9 by fillet welds, the leg size ≥ 8 mm, and the weld surface is ground flat; at the same time, the lower unit fitting 49 and the unit floor base 48 are fixed by bolts 20. The bolt holes are designed as round holes to reduce the possibility of displacement.

[0108] As Figure 2 and Figure 7 shown, in an optional embodiment of the present invention, a horizontal connection structure 50 is provided in the splicing gap of the plurality of glass units 5, including:

[0109] A first card member 51 with one end inserted into the side column 2;

[0110] A second card member 52 that is snap-connected to the first card member 51 and is arranged perpendicular to the plurality of glass units 5;

[0111] A connecting ring 53 inserted between the first card members 51 or between the second card members 52, and the two opposite sides of the connecting ring 53 are slidably nested and connected;

[0112] Wherein, a windproof pin seat 54 is inserted into the horizontal connection structure 50, and the convex part of the windproof pin seat 54 is used for clamping with the horizontal connection structure 50 at the splicing part of the plurality of glass units 5.

[0113] In this embodiment, a horizontal connection structure 50 is provided at the splicing gap of the curtain wall unit. This structure mainly includes: one end of the first card member 51 is inserted into the side column 2. The side column 2 serves as the support structure of the entire glass unit installation frame, providing a solid fixing foundation for the first card member 51, ensuring that the first card member 51 will not easily loosen or displace, thereby laying a foundation for the stability of the subsequent connection structure.

[0114] The second card member 52 forms a snap connection with the first card member 51, and at the same time, the arrangement direction of the second card member 52 is perpendicular to the plurality of glass units 5, so that the second card member 52 can effectively connect and fix the plurality of glass units 5 in the horizontal direction, further enhancing the structural strength at the splicing part of the glass units and preventing the glass units from shaking or separating in the horizontal direction.

[0115] The connecting ring 53 is inserted between the first clamping members 51 or between the second clamping members 52. The two sides of the connecting ring 53 are nested towards each other and are connected in a sliding manner. This can not only absorb the minute deformations of the glass unit caused by factors such as temperature changes and external forces to a certain extent, avoid damage to the connecting structure due to deformation, but also ensure the integrity and continuity of the connecting structure, enabling the multiple glass units 5 to maintain a good connection state at the splicing location.

[0116] The windproof pin seat 54 is inserted into the horizontal connecting structure 50. The windproof pin seat 54 itself has a protruding part, and the protruding part is a telescopic circular component. When the protruding part is extruded by an external force, it will contract inward. Based on this principle, it is clamped with the horizontal connecting structure 50 at the splicing location of the multiple glass units 5. The windproof pin seat 54 further enhances the stability of the horizontal connecting structure 50. Especially when dealing with harsh weather conditions such as strong winds, it can effectively prevent the glass unit from shaking, shifting, or even falling off due to the action of wind force, improving the safety and reliability of the entire glass unit splicing structure.

[0117] As Figure 3 shown, in an optional embodiment of the present invention, the interlayer unit main body 10 includes:

[0118] The longitudinal keel 13 vertically installed on the waterproof panel 12;

[0119] The transverse keel 14 fixedly connected to the drainage structure 7 by means of clamping and gluing;

[0120] The obliquely installed keel 15 arranged obliquely, with the beveled end of the longitudinal keel 13 closely attached to the surface of the obliquely installed keel 15;

[0121] The metal cornice 16 installed on the surface of the obliquely installed keel 15. The metal cornice 16 is attached along the first surface of the obliquely installed keel 15, and the main body part of the metal cornice 16 and the main body part of the obliquely installed keel 15 are fixedly connected by screws 17;

[0122] The top of the metal cornice 16 is fixedly connected to the transverse keel 14 through the second connecting structure 18. The flat end of the longitudinal keel 13 is connected to the waterproof panel 12 through the third connecting structure 19. The beveled end of the longitudinal keel 13 is fixedly connected to the obliquely installed keel 15 by bolts 20 and the first fixing member 21. The bottom of the metal cornice 16 is fixedly connected to the obliquely installed keel 15 through the fourth connecting structure 22.

[0123] In this embodiment, the longitudinal keel 13 is vertically installed on the waterproof panel 12, providing vertical stability for the entire interlayer unit. Its flat end is connected to the waterproof panel 12 through the third connection structure 19. The third connection structure 19 connects the longitudinal keel 13 to the building through screws 17, bolts 20, and the third fixing member 37, ensuring a tight fit between the longitudinal keel 13 and the waterproof panel 12 and enabling effective transmission of vertical loads.

[0124] The transverse keel 14 is fixedly connected to the drainage structure 7 in a snap-fit and glued manner. The snap-fit method enables the transverse keel 14 to be quickly and accurately installed in place with the drainage structure 7; the glued method uses a high-strength adhesive to enhance the sealing and stability of the connection, preventing rainwater and the like from seeping in at the connection.

[0125] The inclined keel 15 is inclined in the main body 10 of the interlayer unit. Its inclination angle can meet the requirements of the special shape of the building facade, adding a unique visual effect to the building. At the same time, the inclined end of the longitudinal keel 13 closely adheres to the surface of the inclined keel 15 and is fixedly connected to the inclined keel 15 through bolts 20 and the first fixing member 21. The bolts 20 provide the inclined keel 15 with strong tensile and shear force bearing capacities, and the first fixing member 21 is a special connecting plate that firmly connects the longitudinal keel 13 and the inclined keel 15, ensuring that the two can work together when bearing external forces and jointly resist deformation and damage.

[0126] The metal cornice 16 is installed on the surface of the inclined keel 15 and is arranged along the first surface of the inclined keel 15. It not only has a decorative effect, enhancing the overall beauty of the building, but also has practical functions such as rain shielding and sun shading. The main part of the metal cornice 16 is fixedly connected to the main part of the inclined keel 15 through screws 17. The screws 17 are evenly distributed at the connection part, ensuring a tight fit and firm connection between the metal cornice 16 and the inclined keel 15, and effectively preventing the metal cornice 16 from shaking or falling off under external forces such as wind.

[0127] As Figure 3 and Figure 4 shown, in an alternative embodiment of the present invention, the second connection structure 18 includes:

[0128] A first connecting member 23 snapped onto the metal cornice 16. The first connecting member 23 is fixedly connected to the metal cornice 16 through the screw 17;

[0129] A U-shaped snap-fit member 24 for snap-fitting the first connecting member 23 to the protruding part of the transverse keel 14;

[0130] A second connecting member 25 inserted at the edge of the transverse keel 14, wherein the second connecting member 25 is closely attached to the surface of the metal overhanging eave 16;

[0131] A third connecting member 26 fixedly connected to the bottom of the transverse keel 14 by means of the screw 17;

[0132] The second fixing member 27 is fixedly connected to the oblique keel 15 and the third connecting member 26 by the bolt 20 .

[0133] In this embodiment, the first connecting member 23 is the part directly connected to the metal eaves 16 and is fixedly connected by screws 17, which effectively prevents the two from relative displacement or separation when subjected to external forces, thereby ensuring the firmness and stability of the connection.

[0134] The U-shaped clamping member 24 clamps the first connecting member 23 with the protruding part of the transverse keel 14, and its opening size matches the protruding part of the transverse keel 14. During the installation process, the U-shaped clamping member 24 can be sleeved on the protruding part of the transverse keel 14, and the first connecting member 23 can be firmly clamped through the elastic deformation and friction of its U-shaped structure, which is not only convenient and quick to install, but also can absorb and disperse external forces to a certain extent, reduce the impact on the connection part, and improve the reliability and durability of the entire connection structure.

[0135] The second connecting member 25 is inserted into the edge of the transverse keel 14 and fits closely with the surface of the metal overhanging eave 16 to form a sealing structure, thereby reducing the infiltration of impurities such as rainwater and dust, preventing the connection parts from being corroded and damaged, and extending the service life of the connection structure. In addition, the second connecting member 25 also plays a role in supporting and fixing the metal overhanging eave 16 to a certain extent, so that it can remain stable when subjected to external forces such as wind.

[0136] The third connecting member 26 is fixedly connected to the bottom of the transverse keel 14 by means of screws 17, and is mainly used to support and reinforce the second fixing member 27. By using the screws 17 to ensure a tight connection between the third connecting member 26 and the transverse keel 14, load and stress can be effectively transferred.

[0137] The second fixing member 27 is fixedly connected to the oblique keel 15 and the third connecting member 26 by bolts 20. The bolts 20 provide a strong connection force to ensure that the second fixing member 27 will not loosen or fall off when subjected to various external forces. The second fixing member 27 enhances the integrity and stability of the entire connection structure, so that when the metal eaves 16 is subjected to external forces in different directions, the force can be dispersed to the transverse keel 14 and the oblique keel 15 through the second connection structure 18, and together resist deformation and damage.

[0138] like Figure 3 andFigure 5 As shown in Figure 5 , in an alternative embodiment of the present invention, the third connection structure 19 includes:

[0139] A fourth connector 28 installed on the bottom side of the waterproof panel 12;

[0140] A fifth connector 29 fixedly connected to the fourth connector 28 by the screw 17;

[0141] The third connector 26 connected to the top of the fifth connector 29 by the screw 17;

[0142] A sixth connector 30 fixedly connected to the fifth connector 29 by the screw 17. A drain hole 31 is provided on the side of the space formed by the sixth connector 30 and the fifth connector 29. The sixth connector 30 is fixedly connected to the longitudinal keel 13 by the screw 17;

[0143] A seventh connector 32 fixedly connected to the bottom of the sixth connector 30 and the fifth connector 29 together by the screw 17;

[0144] An eighth connector 33 inserted at the bottom of the fifth connector 29 and the bottom of the seventh connector 32;

[0145] A ninth connector 34 installed on the bottom surface of the eighth connector 33;

[0146] A tenth connector 35 located on the bottom surface of the ninth connector 34. The tenth connector 35 has an integrally formed bolt projection 36, and the tenth connector 35 fixedly connects the eighth connector 33 and the ninth connector 34 through the bolt projection 36;

[0147] A third fixing member 37 fixedly connected to the longitudinal keel 13 and the third connector 26 by the bolt 20.

[0148] In this embodiment, the fourth connector 28 is installed on the bottom side of the waterproof panel 12 and is mainly fixed to the waterproof panel 12 by screws of appropriate size.

[0149] The fifth connector 29 is a three-sided closed and bottom-open component. There are catches on this component that match the eighth connector 33 and the third connector 26, which can make its connection with the eighth connector 33 and the third fixing member 37 more closely fitted. The fifth connector 29 cooperates with other multiple connection components to jointly build a stable connection system for supporting the longitudinal keel 13.

[0150] The third connecting member 26 is connected to the top end of the fifth connecting member 29 by screws 17, and can further transfer the force transmitted by the fifth connecting member 29 to other structural components, ensuring the balanced force of the entire connection structure.

[0151] The sixth connecting member 30 is fixedly connected to the fifth connecting member 29 by screws 17. Drainage holes 31 are provided on the side of the space enclosed by the two, which can effectively drain rainwater or other liquids accumulated at the connection part, prevent moisture from corroding and damaging the connection structure, and extend the service life of the connection structure. At the same time, the sixth connecting member 30 is also fixedly connected to the longitudinal keel 13 by screws 17, enhancing the integrity and stability of the entire connection structure.

[0152] The seventh connecting member 32 is fixedly connected to the bottom of the sixth connecting member 30 and the fifth connecting member 29 by screws 17, so that the three are simultaneously fixed by the screws 17. The presence of the seventh connecting member 32 enables the connection structure to better disperse stress when bearing external forces, reduce the situation of local stress concentration, and improve the reliability and durability of the connection structure.

[0153] The eighth connecting member 33 is inserted at the bottom of the fifth connecting member 29 and the bottom of the seventh connecting member 32, and is inserted through the design of a suitable buckle. This not only realizes the preliminary positioning of the eighth connecting member 33 with the fifth connecting member 29 and the seventh connecting member 32, but also can absorb and buffer the influence of external forces on the connection structure to a certain extent. The shape and size of the eighth connecting member 33 match the sockets at the bottoms of the fifth connecting member 29 and the seventh connecting member 32 to ensure firm insertion and not easy to loosen.

[0154] The ninth connecting member 34 is installed on the bottom surface of the eighth connecting member 33, and a metal sheet of a suitable material is selected. Its main function is to prevent the bolt protrusion 36 from being over-tightened during the installation of the tenth connecting member 35, causing rigid damage to the eighth connecting member 33 and the tenth connecting member 35, thereby enhancing the resistance of the curtain wall unit to external force impacts.

[0155] The third fixing member 37 tightly connects the longitudinal keel 13 and the third connecting member 26 together, further enhancing the stability and reliability of the third connection structure 19, ensuring that the third fixing member 37 will not loosen or fall off when bearing various external forces, making the connection between the longitudinal keel 13 and the waterproof panel 12 more firm, and capable of effectively resisting the action of external forces such as wind and earthquake.

[0156] As Figure 3 and Figure 6 shown, in an alternative embodiment of the present invention, the fourth connection structure 22 includes:

[0157] An eleventh connecting member 38 clamped to the bottom of the obliquely installed keel 15, and the eleventh connecting member 38 is fixedly connected to the obliquely installed keel 15 by the screws 17;

[0158] A twelfth connecting member 39 for fixedly connecting the metal cornice 16 and the eleventh connecting member 38 with the screw 17;

[0159] A V-shaped clamping member 40 is arranged in the middle part between the eleventh connecting member 38 and the twelfth connecting member 39;

[0160] The eleventh connecting member 38 is fixedly connected to a thirteenth connecting member 41 through the U-shaped clamping member 24;

[0161] The thirteenth connecting member 41 fixedly connects the eleventh connecting member 38 and a fourteenth connecting member 42 at the bottom of the metal cornice 16 with the screw 17. A drain hole 31 is formed on the side surface of the fourteenth connecting member 42, and a one-way clamping member 43 is placed between the fourteenth connecting member 42 and the twelfth connecting member 39.

[0162] In this embodiment, the eleventh connecting member 38 is clamped at the bottom of the obliquely installed keel 15 to achieve a preliminary stable connection; meanwhile, the eleventh connecting member 38 is further fixedly connected to the obliquely installed keel 15 with the screw 17.

[0163] The twelfth connecting member 39 mainly fixedly connects the metal cornice 16 and the eleventh connecting member 38. The V-shaped clamping member 40 is used between the two to prevent the bottom of the metal cornice 16 from loosening from the obliquely installed keel 15, and can play a buffering and protecting role, and can effectively transmit loads and stresses.

[0164] The eleventh connecting member 38 is fixedly connected to the thirteenth connecting member 41 through the U-shaped clamping member 24. The opening size of the U-shaped clamping member 24 matches the protruding part of the thirteenth connecting member 41. Through the elastic deformation and friction force of its U-shaped structure, a stable clamping is achieved. It is not only convenient and fast to install, but also can absorb and disperse external forces to a certain extent, reducing the impact on the connecting part. The thirteenth connecting member 41 fixedly connects the eleventh connecting member 38 and the fourteenth connecting member 42 at the bottom of the metal cornice 16 with the screw 17, enhancing the integrity and stability of the entire connecting structure.

[0165] The fourteenth connecting member 42 is installed at the bottom of the metal cornice 16, and a drain hole 31 is formed on the side surface to prevent rainwater and other liquids on the building facade from seeping into the connecting part and being unable to drain. The drain hole 31 can timely drain these liquids out of the curtain wall, preventing moisture from accumulating at the connecting part, avoiding corrosion and damage to the connecting structure, and extending the service life of the connecting structure.

[0166] The one-way snap-in part 43 is placed between the fourteenth connecting part 42 and the twelfth connecting part 39. The one-way snap-in part 43 is designed with barbs, having a special one-way snap-in function. It can only be snapped into the gap between the fourteenth connecting part 42 and the twelfth connecting part 39 from the outside direction, and can be firmly fixed in this position after being snapped in, preventing relative displacement between the fourteenth connecting part 42 and the twelfth connecting part 39 when subjected to external forces. The presence of the one-way snap-in part 43 further enhances the connection stability between the fourteenth connecting part 42 and the twelfth connecting part 39, ensuring a more reliable connection between the metal cornice 16 and the obliquely installed keel 15.

[0167] As Figure 8 shown, in an optional embodiment of the present invention, the drainage structure 7 includes:

[0168] A drainage groove 56 installed on the first surface at the splicing gap of the unit upper cross beam 55 on the indoor side of the building. The contact position between the drainage groove 56 and the unit upper cross beam 55 is sealed and glued with a sealant 57;

[0169] A waterproof rubber sheet 58 installed on the first surface at the splicing gap of the unit upper cross beam 55 on the outdoor side of the building. The contact position between the waterproof rubber sheet 58 and the unit upper cross beam 55 is sealed and glued with the sealant 57;

[0170] The drainage holes 31 are provided on both sides of the splicing gap of the protruding part of the unit upper cross beam 55;

[0171] Among them, the splicing gap of the unit upper cross beam 55 is sealed with the sealant 57.

[0172] In this embodiment, the drainage structure 7 is integrally arranged obliquely. The material of the installed drainage groove 56 is selected to have good corrosion resistance and strength to ensure its stable operation in the indoor environment for a long time. The shape is designed to be strip-shaped, matching the trend of the splicing gap of the unit upper cross beam 55, capable of comprehensively covering the splicing gap, effectively collecting a small amount of moisture that may seep in from the gap, and the edge position is sealed and glued with the sealant 57.

[0173] The sealant 57 has good adhesiveness and sealing performance, and can firmly bond the drainage groove 56 and the unit upper cross beam 55 together to form a sealed whole. This sealing method can not only prevent moisture from leaking into the room from the contact position between the drainage groove 56 and the unit upper cross beam 55, but also enhance the installation firmness of the drainage groove 56, preventing it from loosening or shifting during use. When a small amount of moisture seeps into the room from the splicing gap, the drainage groove 56 can quickly collect this moisture and flow from the higher position on the inner side of the building to the lower position on the outer side of the building, avoiding the accumulation of moisture on the inner side of the building and protecting the building from water damage.

[0174] The waterproof rubber sheet 58 is made of rubber or similar materials with excellent waterproof performance and flexibility, which can adapt to complex environmental conditions such as outdoor temperature changes and ultraviolet radiation, maintain good waterproof effect, and closely fit at the splicing joints to form an effective waterproof barrier.

[0175] The edge position of the waterproof rubber sheet 58 is also sealed and bonded with sealant 57 to form a reliable sealing layer, preventing moisture such as rainwater and snow water from the outside from seeping into the building interior through the splicing joints. While blocking the intrusion of moisture, it can also reduce the entry of air and dust to a certain extent, improving the overall sealing and insulation performance of the building.

[0176] Drainage holes 31 are provided on both sides of the splicing joint of the protruding part of the upper crossbeam 55 of the unit. The shape of the drainage holes 31 is set as oval or strip-shaped, with appropriate size, which can not only ensure the smooth discharge of moisture, but also not affect the structural strength of the upper crossbeam 55 of the unit due to too large aperture.

[0177] As Figure 9 shown, in an optional embodiment of the present invention, the ventilation device 8 is located in the bottom area of the interlayer plate 3, including:

[0178] A window 59 with an opening and closing angle that can reach 90°;

[0179] A hinge 60 that rolls the window and the interlayer structure;

[0180] A wind brace 61 that provides a supporting role for the window 59, with one end of the wind brace 61 connected to the window 59 and the other end connected to the building;

[0181] A closing clip 62 located at the edge of the window 59, which can close and clamp the window 59 with the building and block the ventilation opening.

[0182] In this embodiment, the window 59 is made of materials that are strong, durable and have certain heat insulation and sound insulation properties, such as an aluminum alloy frame with insulating glass. It can not only ensure the structural strength of the window 59, but also effectively reduce the heat transfer and noise interference between indoors and outdoors when the device is closed. The maximum opening and closing angle of the window 59 can reach 90°, which provides great convenience and flexibility for users. When a large ventilation volume is required, the window 59 can be fully opened to 90°, enabling the full circulation of indoor and outdoor air, quickly exhausting the dirty air indoors and introducing fresh air to improve the indoor air quality; at the same time, the 90° opening and closing angle is also convenient for cleaning and maintaining the outside of the window 59, facilitating the operation of the staff.

[0183] The hinge 60 connects the window body 59 and the interlayer structure in a rolling connection manner, enabling the window body 59 to easily perform the opening and closing actions. The hinge 60 is made of high-strength metal material and its surface is treated against corrosion to adapt to different environmental conditions and extend the service life.

[0184] One end of the wind brace 61 is connected to the window body 59 and the other end is connected to the building structure, thus forming a stable support system. At the same time, the wind brace 61 adopts a design with adjustable length, which is convenient for users to adjust the length according to actual needs, so as to control the opening and closing angle of the window body 59.

[0185] The closing clip 62 is installed at the edge position of the window body 59 and is made of a material with certain elasticity and sealing performance, such as rubber or silica gel. When the window body 59 is closed, the closing clip 62 can closely fit at the gap between the window body 59 and the building, completely blocking the ventilation opening, effectively preventing adverse factors such as external dust, rain, and noise from entering the room; its shape and size match the contact part between the window body 59 and the building, and can provide uniform sealing pressure to ensure good sealing effect.

[0186] In the above embodiments of the present invention, the installation is convenient and the cost is low. The overall unit plate is split at the interlayer position into an interlayer unit and a glass unit. The interlayer unit can be composed by combining interlayer plates according to the grid size and processing capacity, and the glass unit can also be composed by combining glass plates according to the grid size and processing capacity, reducing the installation difficulty and the manufacturing, transportation, and installation costs of the curtain wall unit; due to the reduced distance between the supports after splitting, and by combining the original male and female columns into middle columns, the cross-section of the columns can be reduced to save materials, and at the same time, the processing and installation difficulty can be reduced, making the material utilization more economical and reasonable.

[0187] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
