Description

Technical Field

[0001] This invention relates to the field of architectural decoration technology, and in particular to an external decorative unit for architectural decoration. Background Technology

[0002] Existing architectural decoration primarily utilizes curtain walls or glass windows. While curtain walls can completely conceal the building's main structure and create a visually appealing facade, their external attachment to the building facade poses certain safety risks, especially for high-rise buildings and apartments, where their use is increasingly restricted, causing inconvenience for decoration work. While glass windows offer better stability and safety, and can create a similar decorative surface to curtain walls to some extent, existing window structures are installed within pre-drilled openings on the building facade, failing to completely conceal the main structure and significantly impacting the overall aesthetic appeal of the decorative surface, resulting in a less than ideal appearance. Therefore, there is an urgent need in the architectural decoration field for a decorative structure system that can balance the aesthetic appeal of curtain walls with the safety and stability of window structures. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an external decorative unit system for buildings, which solves the problems of limited application of curtain wall structure and window structure affecting appearance in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An architectural decorative external unit includes multiple crossbeams and columns forming a grid-like keel. The outer sides of the crossbeams and columns are flush. Each crossbeam includes multiple main crossbeams and secondary crossbeams connected end-to-end, and each column includes multiple main columns and secondary columns connected end-to-end. The grid-like keel formed entirely by the main crossbeams and columns is the first grid keel, and the rest are the second grid keels. The inner sides of the main crossbeams and columns are higher than the secondary crossbeams and columns, respectively, so that the inner side of the first grid keel can extend into and be fixed to a reserved window opening on the building facade. A first external unit is installed on the first grid keel, and a second external unit is installed on the second grid keel.

[0006] As an optimization, an upward-facing hanging groove is provided on the outer side of the crossbeam, and the first and second external hanging units are connected to the hanging groove through a hanging member.

[0007] As an optimization, a snap-fit ​​groove with an opening facing horizontally is provided on the outside of the column, and the opening direction of the snap-fit ​​groove of each column is consistent. The first external unit and the second external unit are snapped into the snap-fit ​​groove through snap-fit ​​components.

[0008] As an optimization, both the crossbeam and the column include a rectangular profile body with an extended L-shaped plate or U-shaped plate integrally formed on its outer side. The L-shaped plate or U-shaped plate and the profile body form the hanging groove and snap-fit ​​groove.

[0009] As an optimization, the opening width of the hook groove and the snap groove gradually decreases with the groove depth. The hook and snap are respectively hooked and snapped in the hook groove and the snap groove by a rubber strip with a conical cross section.

[0010] As an optimization, two mounting slots are distributed along the height direction of the crossbeam, and two snap-fit ​​slots are distributed along the width direction of the column, which are respectively used to install the first external hanging unit or the second external hanging unit in the adjacent grid keel.

[0011] As an optimization, the first external unit includes insulated tempered glass or a glass window sash, and the second external unit includes an integrated aluminum insulation panel or insulated tempered glass with an aluminum back panel.

[0012] As an optimization, a sealing element hanging groove is provided on the outside of the crossbeam, and a first sealing component is provided in the horizontal joint between adjacent first or second external hanging units, the first sealing component being hooked to the sealing element hanging groove.

[0013] As an optimization, the first sealing assembly includes a support member that is attached to the groove of the sealing element. A screw hole is provided at one end of the support member away from the crossbeam. It also includes a sealing plate with a Z-shaped cross section. A connecting bolt is installed at the bottom of the groove of the sealing plate. One end of the groove of the sealing plate extends into the horizontal joint between adjacent first or second external units and is connected to the screw hole on the support member through the connecting bolt. The two wings at the other end are respectively sealed and fitted to the outer side of the adjacent first or second external unit. An elastic sealing gasket is provided between the sealing plate and the support member.

[0014] As an optimization, a second sealing assembly is installed in the vertical joint of the adjacent first or second external unit.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This invention uses a grid-like keel formed by beams and columns to install the first and second external hanging units. Simultaneously, the beams and columns corresponding to the reserved window openings on the building facade serve as the main beams and columns, extending into and fixing to the inside of the window openings, thus forming a window frame-like structure to bear the weight of the entire keel. The remaining secondary beams and columns are not connected to the building facade, forming an external decorative structure. This invention uses the window frame structure formed by the main beams and columns installed inside the reserved window openings to bear the load, while the entire grid-like keel extends outwards from the building facade, forming a curtain wall-like structure. This achieves a balance between an aesthetically pleasing curtain wall appearance, good window structure safety and stability, a simple structure, convenient construction, high efficiency, and ease of promotion.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] For specific implementation: see: Figure 1-9 ,

[0026] An architectural decorative external unit includes multiple crossbeams and columns forming a grid-like keel. The outer sides of the crossbeams and columns are flush. Each crossbeam includes multiple main crossbeams 1 and secondary crossbeams 2 connected end to end. Each column includes multiple main columns 3 and secondary columns 4 connected end to end. The grid-like keel completely enclosed by the main crossbeams 1 and main columns 3 is the first grid keel, and the rest are the second grid keels. The inner sides of the main crossbeams 1 and main columns 3 are higher than the secondary crossbeams 2 and secondary columns 4, respectively, so that the inner side of the first grid keel can extend into and be fixed in a reserved window opening on the building facade. The secondary crossbeams 2 and secondary columns 4 are fitted or gap-fitted with the beams, walls, or other non-window opening structures of the building facade. A first external unit 5 is installed on the first grid keel, and a second external unit 6 is installed on the second grid keel.

[0027] Specifically, an upward-facing hanging groove 7 is provided on the outer side of the crossbeam, and the first external hanging unit 5 and the second external hanging unit 6 are hung on the hanging groove 7 via a hanging connector 8. A horizontally oriented snap-fit ​​groove 9 is provided on the outer side of the column, and the opening directions of the snap-fit ​​grooves 9 on each column are consistent. The first external hanging unit 5 and the second external hanging unit 6 are snapped on the snap-fit ​​groove 9 via a snap-fit ​​connector 10. Both the crossbeam and the column include a rectangular aluminum alloy profile body, with an extended L-shaped plate or U-shaped plate integrally formed on its outer side. This L-shaped plate or U-shaped plate and the profile body form the hanging groove 7 and the snap-fit ​​groove 9. The opening of the hanging groove 7 and the snap-fit ​​groove 9 gradually decreases with the depth of the groove. The hanging part 8 and the snap-fit ​​part 10 are each provided with a downward tongue. A rubber strip is fitted on the tongue. The cross-section of the rubber strip is conical and has anti-slip grooves on both sides. The hanging part 8 and the snap-fit ​​part 10 are hung and snapped in the hanging groove 7 and the snap-fit ​​groove 9 through the rubber strip. The connection is stable, the sealing is good, and it is not easy to fall off.

[0028] In this embodiment, two hanging grooves 7 are distributed along the height direction of the crossbeam, and two snap-fit ​​grooves 9 are distributed along the width direction of the column, respectively used to install the first external hanging unit 5 or the second external hanging unit 6 in adjacent grid keels. The first external hanging unit 5 includes hollow tempered glass or glass window sash, and the second external hanging unit 6 includes an integrated aluminum plate insulation panel or hollow tempered glass with an aluminum backing plate, or it can be a decorative panel such as aluminum plate, glass, stone, cement fiberboard, or composite board. Since the main function of the second external hanging unit 6 is to shield the main building structure, when hollow tempered glass is used, an aluminum backing plate needs to be installed on its inner side. Specifically, the aluminum backing plate can be installed flush with the hollow tempered glass or with a gap fit, or it can be installed on the building facade, depending on the actual decorative effect.

[0029] In specific implementation, the first external hanging unit 5 and the second external hanging unit 6 are both externally hung on the outside of the keel. The first external hanging unit 5 and the second external hanging unit 6 completely cover the keel and the main building. Horizontal joints and vertical joints are formed between adjacent first external hanging units 5 or second external hanging units 6. Therefore, in order to improve water tightness and air tightness, a sealing element hanging groove 11 is also provided on the outside of the crossbeam. A first sealing component is provided in the horizontal joint between adjacent first external hanging units 5 or second external hanging units 6. The first sealing component is connected to the sealing element hanging groove 11. The first sealing assembly includes a support member 12 that hooks onto the sealing element hanging groove 11. The support member 12 has a triangular bracket structure, with a hook-on part at one end near the crossbeam for hooking onto the sealing element hanging groove 11. A screw hole is provided at the end of the support member 12 facing away from the crossbeam. It also includes a sealing plate 13 with a Z-shaped cross-section. A connecting bolt is installed at the bottom of the groove of the sealing plate 13. One end of the groove of the sealing plate 13 extends into the horizontal joint between adjacent first external unit 5 or second external unit 6 and is connected to the screw hole on the support member 12 via the connecting bolt. The two wings at the other end are respectively sealed and fitted to the outer side of the adjacent first external unit 5 or second external unit 6. Specifically, sealant is applied between the sealing plate 13 and the outer surface of the first external unit 5 or second external unit 6, and an elastic sealing gasket is provided between the sealing plate 13 and the support member 12. Additionally, depending on actual needs, an eaves board can be inclinedly provided on the lower wing plate of the two wings of the sealing plate 13 to facilitate drainage and improve water tightness.

[0030] A second sealing assembly is installed in the vertical joint of the adjacent first external unit 5 or second external unit 6. The second sealing assembly includes a sealing strip with a circular cross-section installed in the vertical joint, and the aforementioned zigzag sealing plate 13 is installed on the outside of the vertical joint. Sealant is filled between the sealing plate 13 and the first external unit 5 or second external unit 6 and the sealing strip to achieve a good seal.

[0031] During installation, the entire grid-like keel, along with the first external hanging unit 5 and the second external hanging unit 6, can form a prefabricated structure as a whole. By hoisting it to the installation position, the first grid keel is inserted into the reserved window opening on the building facade. Workers can complete the installation and fixing inside the building without the need for scaffolding or other construction auxiliary devices, which greatly improves both safety and construction efficiency.

[0032] This invention uses a grid-like keel formed by beams and columns to install the first and second external hanging units. Simultaneously, the beams and columns corresponding to the reserved window openings on the building facade serve as the main beams and columns, extending into and fixing to the inside of the window openings, thus forming a window frame-like structure to bear the weight of the entire keel. The remaining secondary beams and columns are not connected to the building facade, forming an external decorative structure. This invention uses the window frame structure formed by the main beams and columns installed inside the reserved window openings to bear the load, while the entire grid-like keel extends outwards from the building facade, forming a curtain wall-like structure. This achieves a balance between an aesthetically pleasing curtain wall appearance, good window structure safety and stability, a simple structure, convenient construction, high efficiency, and ease of promotion.
