Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology. More specifically, this invention relates to a segmented building curtain wall structure and its construction method. Background Technology

[0002] A building curtain wall refers to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). Building curtain walls are a common structure in modern large and high-rise buildings, and also serve as decorative components of the building's exterior.

[0003] With the widespread adoption of curtain walls in various buildings, composite curtain walls are increasingly becoming the preferred choice for many construction projects. While they enhance the aesthetics of buildings, improper structural design and construction can lead to numerous safety hazards, such as cracks and water seepage. For example, patent application number 202420649759.1 discloses a composite curtain wall made of aluminum panels and stone slabs, which includes a wall body with an mounting plate on the front. An aluminum panel is located on the left side of the mounting plate, and a stone slab is located on the right side. Although the protective components enhance the building's safety and comfort and effectively prevent adverse effects from external factors, the lack of any waterproofing structure at the joint between the aluminum panel and the stone slab means that water can easily seep through, causing damage to the curtain wall.

[0004] Therefore, ensuring the connection and coordination of various curtain wall forms and avoiding quality problems such as water seepage at the connection gaps are important issues that segmented building curtain walls urgently need to address. Summary of the Invention

[0005] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0006] Another objective of this invention is to provide a segmented building curtain wall structure, which connects a glass curtain wall and a stone curtain wall through a first connector with an arc-shaped portion, allowing rainwater to transition from the arc-shaped portion to the glass curtain wall. This avoids the problem of rainwater seeping into the joint gaps at the connection between the glass curtain wall and the stone curtain wall when they are connected in a plane, thus preventing corrosion of the curtain wall components and reducing their service life.

[0007] To achieve these objectives and other advantages according to the present invention, a segmented building curtain wall structure is provided, comprising:

[0008] The keel frame is constructed from multiple vertically arranged columns and horizontally arranged beams. The columns are fixed at intervals to embedded parts on the main body of the building wall, and the beams are connected between adjacent columns, achieving a stable connection through angle aluminum and bolts.

[0009] A pair of stone curtain walls are respectively installed at the upper and lower ends of the keel frame. Each stone curtain wall has two sets of back bolts on its back. Each stone curtain wall is connected to the hanger at a preset position on the crossbeam through the two sets of back bolts, thereby fixing it to the crossbeam at the upper and lower ends of the keel frame.

[0010] A pair of aluminum alloy decorative curtain panels overlap and are fixed at both ends of a pair of stone curtain walls in a vertical direction, forming an installation space with the middle of the pair of stone curtain walls.

[0011] A glass curtain wall is installed in the installation space. The glass curtain wall and the stone curtain wall are connected by a pair of first connecting members. Each first connecting member consists of a vertical part, an arc-shaped part, and a snap-fit ​​part. The vertical part is fixed to the stone curtain wall and close to the end of the glass curtain wall. One end of the arc-shaped part is connected to the vertical part, and the other end is connected to the snap-fit ​​part. The arc-shaped part is made of elastic material, and the snap-fit ​​part snaps onto the end of the glass curtain wall.

[0012] Preferably, the stone curtain wall has a first slot on its outer side, the first slot having an upper end and a lower end, the upper end and the lower end being connected, the upper end opening facing the top of the stone curtain wall, the lower end opening facing the outer side of the stone curtain wall, and the lower end extending upward with a groove. A sliding rod passes through the upper end and the lower end, and a telescopic spring is sleeved on the sliding rod and located on the outer side of the upper end. One end of the telescopic spring is fixed to the sliding rod, and the other end is connected to a limit block. A first rack is provided on the sliding rod and located at the lower end, and a gear is provided at the lower end. The gear is nested on a concentric shaft and located between the first rack and the groove, and the first rack meshes with the gear.

[0013] The aluminum alloy decorative panel has a second slot, and a sliding groove is formed inside the second slot. A sliding block is provided in the sliding groove, and a second rack is fixedly connected to one end of the sliding block. The second rack can mesh with the gear. The lower end of the first slot is flush with the lower end of the second slot.

[0014] Under the elastic reset of the telescopic spring, the movement of the first rack drives the rotation of the gear, which in turn drives the movement of the second rack to engage in the slot.

[0015] Preferably, the aluminum alloy decorative curtain panel has a mounting groove corresponding to the glass curtain wall insertion point. The mounting groove is oriented along the vertical direction of the aluminum alloy decorative curtain panel. A pair of clamps are arranged opposite each other at the opening of the mounting groove along the length of the aluminum alloy decorative curtain panel, with a gap between the clamps. An insert is provided at the edge of the glass curtain wall corresponding to the mounting groove. A pair of second connecting members are provided at the upper and lower ends of the inner side of the mounting groove. Each second connecting member includes:

[0016] A support plate is connected to the mounting groove, with one end of the support plate fixedly connected to the mounting groove and the other end extending horizontally within the mounting groove.

[0017] A pair of support springs, one end of which is connected to the top of the support plate;

[0018] A movable plate includes a connecting end, a locking part, and a sliding end. The connecting end is connected to the other end of a pair of support springs. The locking part is clamped in the gap between a pair of clamping plates. The sliding end contacts the inner wall of the mounting groove and slides along its length direction in the mounting groove as the pair of support springs are compressed or extended.

[0019] The insert on the glass curtain wall is inserted between a pair of second connecting members.

[0020] Preferably, a buffer member is provided between two adjacent segmented stone curtain wall structures, the buffer member comprising:

[0021] The bracket has a double L-shaped structure and is fixed to the keel frame.

[0022] A pair of first buffer blocks are elastically connected to the vertical side of the bracket;

[0023] A pair of second buffer blocks are elastically connected to the lateral side of the bracket.

[0024] Preferably, an elastic compression member is provided on the inner side of the snap-fit ​​portion.

[0025] Preferably, the embedded part is a 500×100×6 angle steel, which is embedded in the main body of the building wall. The column is connected and fixed to the embedded part by bolts, and anti-corrosion gaskets are provided between the bolts and the embedded part.

[0026] This invention is further realized through a construction method for a segmented building curtain wall structure, which includes the following steps:

[0027] Step 1: Measure and lay out the lines according to the construction design drawings to determine the installation positions of multiple columns and beams in the keel frame. First, fix the columns to the embedded parts in the building wall. Then, fix the beams between adjacent columns with angle aluminum and bolts according to the installation positions of a pair of stone curtain walls.

[0028] Step 2: Secure a pair of stone curtain walls to the crossbeam using the back bolt method. Pull the sliding rod in the first slot of the stone curtain wall so that the sliding rod slides upward along the inner side of the first slot to the top of the first slot, compressing the telescopic spring. Then, attach the aluminum alloy decorative curtain panel to the side of the stone curtain wall so that the second rack is attached to one side of the gear. At this point, release the sliding rod, and the sliding rod will reset due to the elastic force of the telescopic spring, thereby driving the first rack to move. The movement of the first rack drives the gear to rotate, and the rotation of the gear drives the second rack to move, thereby causing the second rack to engage in the slot to complete the installation of the stone curtain wall and the aluminum alloy decorative curtain panel. Repeat the above operation to complete the installation of a pair of aluminum alloy decorative curtain panels.

[0029] Step 3: Fix the insert to the edge of the glass curtain wall and the corresponding mounting groove. Insert the insert into the mounting groove and lock it between a pair of second connecting members. Adjust its installation position and stabilize it by the elasticity of the pair of second connecting members, so that the left and right ends of the glass curtain wall are respectively installed with a pair of aluminum alloy decorative curtain panels.

[0030] Step 4: Fix the vertical part of the first connecting member to the corresponding position of the stone curtain wall, and use the snap-fit ​​part of the first connecting member to snap the upper and lower ends of the glass curtain wall. Seal the gaps where the glass curtain wall meets the pair of stone curtain walls and the pair of aluminum alloy decorative curtain panels with sealant to complete the installation of the segmented building curtain wall.

[0031] The present invention has at least the following beneficial effects:

[0032] 1. In the segmented building curtain wall structure of the present invention, the glass curtain wall and the stone curtain wall are connected by a connecting member with an arc-shaped part, so that rainwater can pass from the arc-shaped part to the glass curtain wall, avoiding the problem that when the glass curtain wall and the stone curtain wall are connected in plane, rainwater seeps into the connection gap along the connection between the two and corrodes the various components of the curtain wall and reduces their service life.

[0033] 2. In the segmented building curtain wall structure of the present invention, the stone curtain wall and the alloy decorative curtain panel are connected and adjusted through the coordinated cooperation of the various components of the two.

[0034] 3. In the segmented building curtain wall structure of the present invention, the movement and fine adjustment of the glass curtain wall are achieved through the elastic change in the second connecting member, which has the advantages of simple structure, reliable fine adjustment and stability.

[0035] 4. In the segmented building curtain wall structure of the present invention, a buffer component is provided between the stone curtain walls of two adjacent segmented building curtain wall structures. The buffer block moves in different directions to absorb the impact force of vibration in different directions, effectively reducing the damage caused by earthquakes or other impacts to the segmented building curtain wall structure.

[0036] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0046] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0047] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0048] like Figures 1-7 As shown, the present invention provides a segmented building curtain wall structure, comprising:

[0049] The keel frame is constructed from multiple vertical columns 2 and horizontal beams 3 arranged in the horizontal direction. The columns 2 are fixed at intervals to the embedded parts on the main body of the building wall 1, and the horizontal beams 3 are connected between adjacent columns 2, and a stable connection is achieved by angle aluminum and bolts.

[0050] A pair of stone curtain walls 4 are respectively installed at the upper and lower ends of the keel frame. Each stone curtain wall 4 has two sets of back bolts on its back. Each stone curtain wall 4 is connected to the hanger at a preset position on the crossbeam 3 through the two sets of back bolts, thereby fixing it to the crossbeam 3 at the upper and lower ends of the keel frame.

[0051] A pair of aluminum alloy decorative curtain panels 5 are overlapped and fixed at both ends of a pair of stone curtain walls 4 in a vertical direction, and form an installation space with the middle of the pair of stone curtain walls 4.

[0052] A glass curtain wall 6 is disposed in the installation space. The glass curtain wall 6 is connected to the stone curtain wall 4 by a pair of first connecting members 7. Each first connecting member 7 consists of a vertical part 71, an arc-shaped part 72 and a snap-fit ​​part 73. The vertical part 71 is fixed to the stone curtain wall 4 and close to the end of the glass curtain wall 6. One end of the arc-shaped part 72 is connected to the vertical part 71 and the other end is connected to the snap-fit ​​part 73. The arc-shaped part 72 is made of elastic material, and the snap-fit ​​part 73 snaps onto the end of the glass curtain wall 6.

[0053] In the above technical solution, firstly, a keel frame is constructed. The keel frame is composed of multiple vertically arranged columns 2 and horizontally arranged beams 3. The columns 2 are made of high-strength steel and are fixed to embedded parts by bolts. The embedded parts are made of 500×100×6 angle steel, and anti-corrosion gaskets are provided between the bolts and the embedded parts. The columns 2 are fixed to the embedded parts on the main building wall 1 at intervals and securely to ensure the stability and load-bearing capacity of the entire keel frame. The beams 3 are also made of high-strength steel and are securely connected to adjacent columns 2 by angle steel and bolts to form a complete keel frame system. Next, a pair of stone curtain walls 4 are installed on the keel frame. Each stone curtain wall 4 is composed of multiple stone slabs spliced ​​together and is located at the upper and lower ends of the keel frame, respectively. Each stone curtain wall 4 has two sets of back bolts on its back. These back bolts are connected to hangers at preset positions on the crossbeams 3 using bolts or other fasteners, thus firmly fixing a pair of stone curtain walls 4 to the crossbeams 3 at both ends of the keel frame. Next, a pair of aluminum alloy decorative curtain panels 5 are installed. These panels, made of lightweight and corrosion-resistant aluminum alloy, overlap vertically and are fixed to both ends of the pair of stone curtain walls 4. A certain installation space is formed between the aluminum alloy decorative curtain panels 5 and the stone curtain walls 4, facilitating the subsequent installation of the glass curtain wall 6. Finally, the glass curtain wall 6 is installed. The glass curtain wall 6 is composed of multiple transparent or semi-transparent glass panels and is positioned within the installation space formed by the stone curtain walls 4 and the aluminum alloy decorative curtain panels 5. The glass curtain wall 6 is connected to the stone curtain wall 4 via a pair of first connecting members 7. Figure 8As shown, each first connecting member 7 consists of a vertical part 71, an arc-shaped part 72, and a snap-fit ​​part 73. The vertical part 71 is fixed to the stone curtain wall 4 by bolts or other fasteners and is located near the end of the glass curtain wall 6. The arc-shaped part 72 is made of elastic material (such as rubber or plastic or other materials with sufficient strength and toughness), with one end connected to the vertical part 71 and the other end connected to the snap-fit ​​part 73. The snap-fit ​​part 73 has a unique snap-fit ​​structure, such as a first fixing block and a second fixing block. The tops of the first fixing block and the second fixing block are integrally formed into a whole structure. There is an inwardly recessed groove between the bottom of the first fixing block and the bottom of the second fixing block. The inner thickness of the groove (i.e., the distance from the inner side of the first fixing block to the inner side of the second fixing block) matches the thickness of the glass curtain wall so that the glass curtain wall 6 can be tightly embedded in the groove, thereby achieving a stable fixing effect. An anti-slip structure (made of elastic material such as rubber) is arranged around the groove to prevent the glass curtain wall 6 from slipping. The anti-slip structure can take various forms, such as protrusions, grooves, textures, etc., to increase the friction between the glass curtain wall 6 and the glass curtain wall 6. For example, a series of tiny protrusions are set around the groove as an anti-slip structure. These protrusions can fit tightly against the surface of the glass curtain wall 6, effectively preventing it from slipping. When installing the glass curtain wall 6, it is first placed in the groove of the locking part 73. Then, by adjusting the position of the glass curtain wall 6, it is ensured that it is fully embedded in the groove and fits tightly against the anti-slip structure. Finally, appropriate fasteners (such as bolts, nuts, etc.) are used to firmly connect the glass curtain wall 6 to the locking part 73.

[0054] In another technical solution, a first slot 41 is provided on the outer side of the stone curtain wall 4. The first slot 41 includes an upper end 410 and a lower end 411, which are connected. The upper end 410 opens towards the top of the stone curtain wall 4, and the lower end 411 opens towards the outer side of the stone curtain wall 4. A groove 42 extends upward from the lower end 411. A sliding rod 47 extends through the upper end 410 and the lower end 411. A telescopic spring 45 is sleeved on the sliding rod 47 and located outside the upper end 410. One end of the telescopic spring 45 is fixed to the sliding rod 47, and the other end is connected to a limit block 46. A first rack 48 is provided on the sliding rod 47 and located at one end of the lower end 411. A gear 44 is provided at the lower end 411. The gear 44 is sleeved on a concentric shaft 43 and is located between the first rack 48 and the slot 42. The first rack 48 meshes with the gear 44.

[0055] The aluminum alloy decorative curtain panel 5 has a second slot 51, and a sliding groove 52 is provided inside the second slot 51. A sliding block 53 is provided in the sliding groove 52. One end of the sliding block 53 is fixedly connected to a second rack 54, which can mesh with the gear 44. The lower end 411 of the first slot 41 is flush with the lower end of the second slot 51.

[0056] When the telescopic spring 45 is elastically reset, the first rack 48 moves to drive the gear 44 to rotate, which in turn drives the second rack 54 to move and engage in the slot 42.

[0057] In the above technical solution, a first slot 41 is designed on the outer side of the stone curtain wall 4. The first slot 41 consists of an upper end 410 and a lower end 411, which are interconnected. The opening of the upper end 410 faces the top of the stone curtain wall 4, facilitating the installation and adjustment of the internal structure; while the opening of the lower end 411 faces the outer side of the stone curtain wall 4, providing convenience for subsequent assembly. Inside the lower end 411, an upwardly extending groove 42 is designed for mating with the structure on the aluminum alloy decorative curtain panel 5 to achieve a stable connection. A sliding rod 47 passes through the upper and lower parts of the first slot 41, and the sliding rod 47 can slide freely within the slot. A telescopic spring 45 is sleeved on the outer part of the sliding rod 47 located at the upper end 410. One end of the spring is fixed to the sliding rod 47, and the other end is connected to a limiting block 46 to limit the excessive stretching of the spring and provide a restoring force. At one end of the sliding rod 47 located at the lower end 411, a first rack 48 is designed, which meshes with a gear 44 disposed within the lower end 411. The gear 44 is fitted onto a concentric shaft 43 and can rotate freely. Specifically, the gear 44 is located between the first rack 48 and the slot 42. This design allows the rotation of the gear 44 to simultaneously affect both the first rack 48 and the second rack 54 that meshes with the gear 44. When the aluminum alloy decorative curtain panel 5 is combined with the stone curtain wall 4, the second rack 54 can mesh with the gear 44, thereby achieving linkage between the two. The lower end 411 of the first slot 41 is flush with the lower end of the second slot 51. This design ensures alignment and smooth fit during assembly.

[0058] In actual operation, when it is necessary to install or adjust the position of the aluminum alloy decorative curtain panel 5, the sliding rod 47 can be operated (e.g., manually pushed or driven by other mechanical devices) to slide the sliding rod 47 from the inside of the first slot 41 outward. Then, the aluminum alloy decorative curtain panel 5 is attached to the outside of the stone curtain wall 4, so that the second rack 54 is attached to the outside of the gear 44. After that, the sliding rod 47 is released, and the sliding rod 47 is reset by the elastic force of the telescopic spring 45, so that the first rack 48 moves under the elastic reset action of the telescopic spring 45. This movement will drive the gear 44 to rotate, thereby driving the second rack 54 to move. As the second rack 54 moves, it will gradually engage in the slot 42, thereby achieving a stable connection between the stone curtain wall 4 and the aluminum alloy decorative curtain panel 5. This design not only improves the assembly efficiency between the stone curtain wall 4 and the aluminum alloy decorative curtain panel 5, but also achieves automatic adjustment and stable assembly through the meshing of gear 44, first rack 48, and second rack 54, as well as the reset action of the spring, thereby enhancing the stability and reliability of the overall structure.

[0059] In another technical solution, an installation groove 55 is provided on the aluminum alloy decorative curtain panel 5 at the insertion point of the glass curtain wall 6. The installation groove 55 is arranged in the vertical direction of the aluminum alloy decorative curtain panel 5. A pair of clamping plates 550 are arranged opposite each other at the opening of the installation groove 55 and along the length direction of the aluminum alloy decorative curtain panel 5. There is a gap 551 between the pair of clamping plates 550. An insert 61 is provided on the edge of the glass curtain wall 6 at the corresponding installation groove 55. A pair of second connecting members 8 are provided at the upper and lower ends of the inner side of the installation groove 55. Each second connecting member 8 includes:

[0060] A support plate 81 is connected to the mounting groove 55. One end of the support plate 81 is fixedly connected to the mounting groove 55, and the other end extends horizontally within the mounting groove 55.

[0061] A pair of support springs 82, one end of which is connected to the top of the support plate 81;

[0062] The movable plate 83 includes a connecting end 831, a locking part 832, and a sliding end 833. The connecting end 831 is connected to the other end of a pair of support springs 82. The locking part 832 is clamped in the gap between a pair of clamping plates 550. The sliding end 833 contacts the inner wall of the mounting groove 55 and slides along its length in the mounting groove 55 as the pair of support springs 82 are compressed or extended.

[0063] The insert 61 on the glass curtain wall 6 is inserted between a pair of second connecting members 8.

[0064] In the above implementation scheme, the aluminum alloy decorative curtain panel 5 is designed to have high aesthetic appeal and structural strength. Its surface undergoes special treatment to ensure corrosion resistance and enhance the overall decorative effect. At the predetermined position of the aluminum alloy decorative curtain panel 5, i.e., the area where the glass curtain wall 6 will be inserted, a vertically extending mounting groove 55 is provided. A pair of clamping plates 550 are arranged along the length of the aluminum alloy decorative curtain panel 5 at the opening of the mounting groove 55, forming a small gap 551 between the clamping plates to provide space for subsequent snap-fit ​​connection. The edge of the glass curtain wall 6 is specially equipped with an insert 61. The shape and size of this insert 61 are designed according to the structure of the mounting groove 55 to ensure a tight and secure insertion into the mounting groove 55. A pair of second connecting members 8 are installed at the upper and lower ends of the inner side of the mounting groove 55, respectively. Each second connecting member 8 consists of the following key parts: a support plate 81, which is firmly connected to the inside of the mounting groove 55. One end of the support plate 81 is fixedly connected to the side wall of the mounting groove 55, and the other end extends horizontally within the mounting groove 55, providing a solid foundation for subsequent spring support; a pair of support springs 82, one end of which is tightly connected to the top of the support plate 81. The selection of support springs 82 must ensure sufficient elasticity and maintain stable performance during long-term use; and a moving plate 83, which consists of three parts: a connecting end 831, a locking part 832, and a sliding end 833. The connecting end 831 is connected to the other end of the pair of support springs 82, ensuring that the moving plate 83 can move under the action of the springs. The locking part 832 is cleverly designed to clamp into the gap between the pair of clamping plates 550, which is the key to achieving the locking connection. The sliding end 833 contacts the inner wall of the mounting groove 55. As the support spring 82 is compressed or extended, the moving plate 83 can slide along its length in the mounting groove 55, thereby achieving a firm clamping of the insert 61.

[0065] When the insert 61 on the glass curtain wall 6 is inserted into the mounting groove 55, it will slide along the end face of the movable plate 83 into the mounting groove 55. As the insert 61 continues to penetrate deeper, it will push the sliding end 833 of the movable plate 83, causing the movable plate 83 to move towards the upper and lower ends of the mounting groove 55 under the action of the support spring 82. When the insert 61 is fully inserted, the movable plate 83 will be tightly clamped at the upper and lower ends of the insert 61 under the restoring force of the spring, thus achieving a stable connection between the glass curtain wall 6 and the aluminum alloy decorative curtain panel 5.

[0066] In another technical solution, a buffer member 9 is provided between two adjacent segmented building curtain wall structures made of stone curtain wall 4, the buffer member 9 comprising:

[0067] The bracket 91 has a double L-shaped structure and is fixed to the keel frame.

[0068] A pair of first buffer blocks 92 are elastically connected to the vertical side of the bracket 91;

[0069] A pair of second buffer blocks 93 are elastically connected to the lateral side of the bracket 91.

[0070] In the above technical solution, the bracket 91 is designed in a double L-shape. This design ensures the stability of the bracket 91 and facilitates its fixed connection with the keel frame. The two right-angled sides of the bracket 91 correspond to the vertical and horizontal edges of the stone curtain wall 4, respectively, ensuring that the buffer blocks can cover all possible displacement directions. The bracket 91 is firmly installed on the keel frame with bolts or other fasteners, ensuring its stability under various external conditions. A pair of first buffer blocks 92 and a pair of second buffer blocks 93 are elastically connected to the vertical and horizontal sides of the bracket 91, respectively. The pair of first buffer blocks 92 are made of highly elastic materials, such as rubber and polyurethane, which have good compressibility and resilience. They are connected to the bracket 91 through elastic connectors (such as springs, rubber gaskets, etc.). The two right-angled sides of the upper edge corner of the stone curtain wall 4 abut against the first buffer block 92 and the second buffer block installed at the corresponding positions, respectively. This provides effective buffering when the stone curtain wall 4 experiences minor vertical displacement due to wind pressure, thermal expansion and contraction, etc., preventing direct contact and collision between stone curtain walls. The second buffer block 93 is elastically connected to the lateral side of the bracket 91, that is, to the two horizontal right-angled sides of the bracket 91. These buffer blocks are also made of highly elastic material and are connected to the bracket 91 through elastic connectors. Their existence is to cope with possible lateral displacement of the stone curtain wall 4, and also to protect the stone curtain wall and reduce collisions and friction.

[0071] In practical applications, when two adjacent stone curtain walls 4 experience slight displacement due to external factors (such as wind, temperature, etc.), the first buffer block 92 and the second buffer block 93 absorb the energy brought by these displacements respectively. Through elastic deformation, they mitigate the interaction forces between the stone curtain walls, thereby effectively preventing damage or cracking of the stone curtain walls caused by direct collisions. This design not only improves the overall stability and durability of the curtain wall system but also reduces the costs associated with maintaining or replacing damaged stone.

[0072] In another technical solution, an elastic compression member is provided on the inner side of the snap-fit ​​portion 73. By providing an elastic compression member on the inner side of the snap-fit ​​portion 73, on the one hand, damage to the glass curtain wall 6 is prevented from being caused by the metal snap-fit ​​portion 73; on the other hand, the characteristics of the elastic compression member enable a stable snap-fit ​​connection while also accommodating minor dimensional changes in the snapped components or minor deviations during assembly, thereby improving assembly flexibility and reliability. The elastic compression member is made of rubber, silicone, or other materials with high elastic resilience. The shape and size of the elastic compression member match the groove on the inner side of the snap-fit ​​portion 73, ensuring a tight fit. When the snap-fit ​​portion 73 contacts the glass curtain wall 6, the elastic compression member is subjected to a certain amount of compression, resulting in elastic deformation. This deformation not only helps to firmly snap the glass curtain wall 6 into the snap-fit ​​portion 73 but also absorbs the impact force during assembly to a certain extent, reducing damage to the glass curtain wall 6 caused by improper assembly or material deformation.

[0073] In another technical solution, the embedded part is a 500×100×6 angle steel, which is embedded in the main body of the building wall 1. The column is connected and fixed to the embedded part by bolts, and anti-corrosion gaskets are provided between the bolts and the embedded part. The embedded part is made of 500×100×6 angle steel. This specification of angle steel has sufficient strength and rigidity to withstand the vertical and horizontal loads applied by the curtain wall system. During the manufacturing process, the material of the embedded part must meet relevant standards, such as high-quality carbon structural steel such as Q235B or Q345B, to ensure that it has good mechanical properties and corrosion resistance. Anti-corrosion gaskets are provided between the bolts and the embedded part to improve the durability and service life of both the bolts and the embedded part.

[0074] The present invention also provides a construction method for a segmented building curtain wall structure, which includes the following steps:

[0075] Step 1: Measure and lay out the lines according to the construction design drawings to determine the installation positions of multiple columns 2 and beams 3 in the keel frame. First, fix the columns 2 on the embedded parts of the main body of the building wall 1. Then, fix the beams 3 between adjacent columns 2 with angle aluminum and bolts according to the installation positions of a pair of stone curtain walls 4.

[0076] Step 2: Fix a pair of stone curtain walls 4 to the crossbeam 3 using the back bolt method. Pull the sliding rod 47 in the first slot 41 of the stone curtain wall 4 so that the sliding rod 47 slides upward along the inner side of the first slot 41 to the top of the first slot 41, so that the telescopic spring 45 is in a compressed state. Then, attach the aluminum alloy decorative curtain panel 5 to the side of the stone curtain wall 4, so that the second rack 54 is attached to one side of the gear 44. At this time, release the sliding rod 47. The sliding rod 47 is reset by the elastic force of the telescopic spring 45, thereby driving the first rack 48 to move. The movement of the first rack 48 drives the gear 44 to rotate. The rotation of the gear 44 drives the second rack 54 to move, thereby driving the second rack 54 to engage in the slot 42 to realize the installation of the stone curtain wall 4 and the aluminum alloy decorative curtain panel 5. Repeat the above operation to complete the installation of a pair of aluminum alloy decorative curtain panels 5.

[0077] Step 3: Fix the insert 61 to the edge of the glass curtain wall 6 and the corresponding mounting groove 55. The insert 61 is inserted into the mounting groove 55 and snapped between a pair of second connecting members 8. The installation position is adjusted and stabilized by the elasticity of the pair of second connecting members 8, so that the left and right ends of the glass curtain wall 6 are respectively installed with a pair of aluminum alloy decorative curtain panels 5.

[0078] Step 4: Fix the vertical part 71 of the first connecting member 7 to the corresponding position of the stone curtain wall 4. Connect the upper and lower ends of the glass curtain wall 6 through the snap-fit ​​part 73 of the first connecting member 7. The arc-shaped part 72 extends to the connection between the glass curtain wall and the pair of aluminum alloy decorative curtain panels 5, covering the corresponding position of the connection gap between the two. This prevents rainwater from flowing into the building curtain wall structure through the gap at the connection between the glass curtain wall 6 and the pair of aluminum alloy decorative curtain panels 5. Instead, the water flows out through the arc of the arc-shaped part. The arc-shaped part 72 of the pair of aluminum alloy decorative curtain panels 5 is connected and fixed to the pair of aluminum alloy decorative curtain panels 5 through connectors (such as rivets, screws and nuts).
