Description

Technical Field

[0001] This utility model belongs to the field of building curtain wall technology, and more specifically, it relates to an integrated metal and stone curtain wall structure. Background Technology

[0002] In the field of building curtain walls, stone curtain walls are widely used in various types of buildings due to their unique decorative effect and durability. Existing stone curtain walls are mainly composed of stone panels, steel keel, thermal insulation structure, secondary structural wall, and interior decorative surface. Thermal insulation materials are often pasted on the outside of the secondary structural wall to improve the overall energy-saving and thermal insulation performance of the building. The hot-dip galvanized channel steel keel used to fix the beams and stone panels is fixed to the secondary structural wall through connectors. The connection between the hot-dip galvanized channel steel keel and the galvanized angle steel is either welded on site or fastened with bolts. There are various ways to connect the thick granite stone and the galvanized angle steel, including aluminum alloy bracket connection, stainless steel bracket connection and back bolt connection.

[0003] Existing application number CN202223326214.7 discloses a stone curtain wall, including a wall body. A threaded pipe is fixedly connected to the surface of the wall body, and a bolt is threadedly connected to the inner cavity of the threaded pipe. A fixing frame is fitted onto the surface of the bolt. A storage groove is formed within the inner cavity of the fixing frame. Movable grooves are formed at the four corners of the inner cavity of the storage groove. A spring is fixedly connected to the inner cavity of the movable groove, and a locking block is fixedly connected to the other end of the spring. A stone curtain wall body is housed within the inner cavity of the storage groove. A fixing block is bonded to the back of the stone curtain wall body using adhesive. Threaded holes are formed on the surface of the fixing block. This utility model, through the combined use of the wall body, bolts, fixing frame, storage groove, movable groove, spring, locking block, stone curtain wall body, fixing block, connecting pipe, and expansion buckle, can efficiently and quickly connect and fix the curtain wall. Furthermore, the multiple connections ensure the robustness of the device, thereby guaranteeing its service life.

[0004] Based on the above, in existing stone curtain walls, the stone panels are fixed to the steel keel using connectors; the insulation material is then pasted onto the surface of the interior secondary structural walls. This construction method not only prolongs the construction period but also results in material waste. Furthermore, the interior walls themselves cannot directly meet decorative requirements, necessitating additional secondary decorative treatments such as hanging metal panels, applying paint after secondary plastering, etc., which is both time-consuming and increases labor costs, resulting in low overall construction efficiency. Moreover, the joints of the exterior stone facade are mostly sealed with sealant, but the sealant is prone to aging and requires maintenance, which is time-consuming and labor-intensive. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an integrated metal and stone curtain wall structure. This solves the problems of existing stone curtain walls where stone panels are fixed to steel frames via connectors, and insulation material is adhered to the interior secondary structural wall surface. This construction method not only prolongs the construction period but also results in material waste. Furthermore, the interior walls themselves cannot directly meet decorative requirements, necessitating additional secondary decorative treatments such as hanging metal panels, applying paint after secondary plastering, etc., which is time-consuming and increases labor costs, leading to low overall construction efficiency. Additionally, the joints of the exterior stone facade are often sealed with sealant, but the sealant is prone to aging and requires maintenance, which is time-consuming and labor-intensive.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0023] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides an integrated metal and stone curtain wall structure, including a steel keel structure 1, an interior decorative surface 2, a stone surface layer 3, a thermal insulation filling layer 4, angle steel connectors 5, and connecting components. The interior decorative surface 2 is anchored to the inside of the steel keel structure 1 using aluminum alloy angle brackets; the stone surface layer 3 is installed on the outside of the steel keel structure 1; the thermal insulation filling layer 4 fills the space between the interior decorative surface 2 and the stone surface layer 3; the angle steel connectors 5 are welded to the outside of the steel keel structure 1; and the connecting components are located on the outside of the steel keel structure 1.

[0024] The connecting components include: hot-dip galvanized angle steel 501 and irregular angle bracket 502. Hot-dip galvanized angle steel 501 is bolted to the front side of angle steel connector 5 and has an L-shaped structure. Irregular angle bracket 502 is bolted to the outside of hot-dip galvanized angle steel 501. The main body of irregular angle bracket 502 is rectangular plate-shaped, with two sets of protrusions extending symmetrically up and down along one side of the main body. The lower protrusion has an L-shaped structure and the upper protrusion has a C-shaped structure.

[0025] The connecting components also include: a first corner bracket 503 and a second corner bracket 504. The first corner bracket 503 is snapped onto the outside of the C-shaped protrusion of the irregular corner bracket 502; the second corner bracket 504 is screwed onto the outside of the L-shaped protrusion of the irregular corner bracket 502.

[0026] The connecting components also include: a limiting profile 505 and a stone panel 301. The limiting profile 505 is bolted to the right side of the C-shaped protrusion of the irregular corner bracket 502. Two sets of stone panels 301 are provided, and the two sets of stone panels 301 are respectively connected to the outside of the first corner bracket 503 and the second corner bracket 504 in a groove.

[0027] The specific usage and function of this embodiment are as follows: Before construction, pretreatment is required. The first corner bracket 503 and the second corner bracket 504 are pre-embedded into the slots on the left and right sides of the stone panel 301, respectively, and then bonded and fixed with special structural adhesive for stone to ensure that the connectors and the stone panel 301 form a stable whole. The installation phase is carried out in the following steps: First, the angle steel connector 5 is welded and fixed to the outside of the steel keel structure 1 to form a basic connection support point; then, the hot-dip galvanized angle steel 501 is fastened to the angle steel connector 5 with bolts, and the irregular angle bracket 502 is fixed to one side of the hot-dip galvanized angle steel 501 with bolt kits to build a multi-level connection frame. Among them, the second angle bracket 504 is installed on the outside of the L-shaped structural protrusion of the irregular angle bracket 502 with machine screws, directly realizing the positioning and fixing of the first set of stone panels 301; the first angle bracket 503 is inserted into the C-shaped structural protrusion of the irregular angle bracket 502, and then the limiting profile 505 is fixed to the front of the irregular angle bracket 502 with bolts. The limiting profile 505 provides reliable limiting for the first angle bracket 503, thereby quickly completing the installation of the second set of stone panels 301. At the same time, a gap will be formed after the two sets of stone panels 301 are installed, which facilitates the thermal expansion and contraction between the stone panels 301. By following the above installation logic in a cyclical manner, multiple sets of stone panels 301 can be spliced ​​in an orderly manner, and finally combined to form a complete stone surface layer 3. In addition, through the structural design of hot-dip galvanized angle steel 501 and irregular angle bracket 502, a cavity structure is naturally formed between the stone surface layer 3 and the interior decorative surface 2. This cavity can be filled with thermal insulation material, thereby forming a continuous and complete thermal insulation filling layer 4, which effectively improves the thermal insulation performance of the curtain wall. Example 2

[0028] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: a sealing component, which is disposed inside the stone surface layer 3.

[0029] The sealing assembly includes an alloy sealing strip 6 and an L-shaped support 601. The alloy sealing strip 6 is snapped into the gap between the two sets of stone panels 301. Two sets of L-shaped supports 601 are provided, and the two sets of L-shaped supports 601 are fixedly connected to the back of the alloy sealing strip 6. The two sets of L-shaped supports 601 and the alloy sealing strip 6 form a π-shaped structure.

[0030] The sealing assembly also includes: a sliding groove 602 and a buffer strip 603. Two sets of sliding grooves 602 are provided, and the two sets of sliding grooves 602 are opened on the left and right sides of the alloy sealing strip 6. Two sets of buffer strips 603 are provided, and the two sets of buffer strips 603 are fixedly installed inside the two sets of sliding grooves 602.

[0031] The sealing assembly also includes a sealing seam 3011 and a sealing edge 604. The sealing seam 3011 is opened on the left and right sides of the two sets of stone panels 301. Two sets of sealing edges 604 are provided, and the two sets of sealing edges 604 are slidably connected inside the two sets of sliding grooves 602.

[0032] The specific usage and function of this embodiment are as follows: After the gap is formed by the installation of the two sets of stone panels 301, the alloy sealing strip 6 is embedded into the gap to fill and seal it. The two sets of L-shaped supports 601 serve as the supporting structure for the alloy sealing strip 6, providing stable support and limiting within the gap, and together with the alloy sealing strip 6, forming a π-shaped structure. This special structure provides reliable support while possessing excellent elastic adaptability, flexibly responding to changes in the gap size caused by thermal expansion and contraction of the two sets of stone panels 301.

[0033] When the alloy sealing strip 6 is inserted between the two sets of stone panels 301, it simultaneously drives the two sets of sealing edges 604 into the corresponding sealing joints 3011, further precisely limiting the position of the alloy sealing strip 6 and ensuring that it does not shift within the gap. Furthermore, the two sets of buffer strips 603 installed inside the sliding groove 602 significantly enhance the adaptability of the sealing edges 604. Under the elastic action of the buffer strips 603, the alloy sealing strip 6 can adapt to dimensional changes in the gap caused by thermal expansion and contraction, while also effectively buffering vibrations within a certain range, improving the overall structural stability. Moreover, the buffer strip 603 is sealed within the sliding groove 602 through the sealing edges 604, reducing direct contact with the external environment, thereby effectively extending the service life of the buffer strip 603 and even the entire sealing assembly, ensuring the long-term sealing performance of the curtain wall.
