DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0021] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0022] like Figures 1 to 7 As shown, the present invention provides a segmented building curtain wall structure, comprising: The keel frame is constructed by a plurality of columns 2 arranged in the vertical direction and beams 3 arranged in the horizontal direction. The columns 2 are fixed at intervals on the embedded parts on the building wall body 1, and the beams 3 are connected between adjacent columns 2, and a stable connection is achieved through angle aluminum and bolts; A pair of stone curtain walls 4, which are respectively arranged at the upper and lower ends of the keel frame, and two sets of back bolts are arranged on the back of each stone curtain wall 4. Each stone curtain wall 4 is connected to the hangers at the preset positions on the beam 3 through the two sets of back bolts, so as to be fixed on the beams 3 at the upper and lower ends of the keel frame; A pair of aluminum alloy decorative curtain panels 5, which are overlapped and fixed at both ends of a pair of stone curtain walls 4 in the vertical direction, and form an installation space between the pair of stone curtain walls 4; A glass curtain wall 6 is arranged in the installation space. The glass curtain wall 6 is connected to the stone curtain wall 4 through a pair of first connecting members 7. Each first connecting member 7 consists of a vertical portion 71, an arc portion 72 and a clamping portion 73. The vertical portion 71 is fixed on the stone curtain wall 4 and close to the end of the glass curtain wall 6. One end of the arc portion 72 is connected to the vertical portion 71, and the other end is connected to the clamping portion 73. The arc portion 72 is made of elastic material, and the clamping portion 73 is clamped at the end of the glass curtain wall 6.

[0023] In the above technical solution, first, a keel frame is constructed. The keel frame is constructed by a plurality of columns 2 arranged in the vertical direction and beams 3 arranged in the horizontal direction. The columns 2 are made of high-strength steel. The columns 2 are connected and fixed with embedded parts by bolts. The embedded parts are made of 500×100×6 angle steel. Anti-corrosion gaskets are provided between the bolts and the embedded parts. The columns 2 are fixed to the embedded parts on the main body 1 of the building wall at intervals and firmly to ensure the stability and load-bearing capacity of the entire keel frame. The beams 3 are also made of high-strength steel. They are firmly connected with the adjacent columns 2 by angle aluminum 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 made of a plurality of stone panels and is respectively arranged at the upper and lower ends of the keel frame. Two groups of back bolts are arranged on the back of each stone curtain wall 4. These back bolts are connected to the hangers at the preset positions on the beam 3 by bolts or other fasteners, so as to firmly fix a pair of stone curtain walls 4 on the beams 3 at the upper and lower ends of the keel frame. Then, a pair of aluminum alloy decorative curtain panels 5 are installed. The aluminum alloy decorative curtain panels 5 are made of lightweight and corrosion-resistant aluminum alloy materials. They are overlapped and fixed at the two ends of a pair of stone curtain walls 4 in the vertical direction. A certain installation space is formed between the aluminum alloy decorative curtain panels 5 and the stone curtain walls 4, which provides convenience for 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 a plurality of transparent or translucent glass panels spliced ​​together and is arranged in the installation space formed by the stone curtain wall 4 and the aluminum alloy decorative curtain panels 5. The glass curtain wall 6 is connected to the stone curtain wall 4 by a pair of first connecting members 7. As shown in FIG. Figure 8As shown, each first connecting member 7 is composed of a vertical portion 71 , an arc portion 72 and a clamping portion 73 . The vertical portion 71 is fixed to the end of the stone curtain wall 4 and close to the glass curtain wall 6 by bolts or other fasteners. The arc portion 72 is made of elastic material (such as rubber or plastic or other materials with sufficient strength and toughness), one end of which is connected to the vertical portion 71, and the other end of which is connected to the clamping portion 73. The clamping portion 73 has a unique clamping structure. For example, the structure of the clamping portion 73 may include: a first fixing block and a second fixing block. The tops of the first fixing block and the second fixing block are integrally formed to form an integral structure. There is an inwardly concave 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 materials such as rubber) is arranged around the groove to prevent the glass curtain wall 6 from sliding off. The anti-slip structure can take various forms, such as protrusions, grooves, textures, etc., to increase the friction between the glass curtain wall 6. For example, a series of tiny protrusions are arranged around the groove as an anti-slip structure. These protrusions can fit tightly on the surface of the glass curtain wall 6, effectively preventing it from slipping. When installing the glass curtain wall 6, first place it in the groove of the clamping portion 73. Then, by adjusting the position of the glass curtain wall 6, ensure that it is completely embedded in the groove and fits tightly with the anti-slip structure. Finally, use appropriate fixings (such as bolts, nuts, etc.) to firmly connect the glass curtain wall 6 and the clamping portion 73.

[0024] In another technical solution, a first slot 41 is provided on the outer side of the stone curtain wall 4, and the first slot 41 includes an upper end 410 and a lower end 411, the upper end 410 and the lower end 411 are connected, the upper end 410 opens toward the top of the stone curtain wall 4, the lower end 411 opens toward the outer side of the stone curtain wall 4, and the lower end 411 extends upward with a slot 42. The upper end portion 410 and the lower end portion 411 are penetrated by a sliding rod 47, and a telescopic spring 45 is sleeved on the sliding rod 47 and located outside the upper end portion 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, and a first rack 48 is provided on one end of the sliding rod 47 and located at the lower end portion 411, and a gear 44 is provided at the lower end portion 411, and the gear 44 is sleeved on the concentric shaft 43, and the gear 44 is located between the first rack 48 and the slot 42, and the first rack 48 is meshed with the gear 44; The aluminum alloy decorative curtain plate 5 is provided with a second slot hole 51, a slide groove 52 is provided inside the second slot hole 51, a sliding block 53 is provided inside the slide groove 52, one end of the sliding block 53 is fixedly connected with a second rack 54, and the second rack 54 can mesh with the gear 44, wherein the lower end 411 of the first slot hole 41 is flush with the lower end of the second slot hole 51; Wherein, under the elastic reset of the telescopic spring 45 , the first rack 48 moves to drive the gear 44 to rotate and then drives the second rack 54 to move and snap into the snap slot 42 .

[0025] In the above technical solution, a first slot 41 is designed on the outer side of the stone curtain wall 4, and the first slot 41 is composed of an upper end 410 and a lower end 411, and the two parts are connected to each other. The opening of the upper end 410 faces the top of the stone curtain wall 4, which is convenient for 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, which provides convenience for subsequent assembly. In the lower end 411, a slot 42 extending upward is designed to cooperate with the structure on the aluminum alloy decorative curtain plate 5 to achieve a stable connection. A sliding rod 47 is passed through the upper and lower parts of the first slot 41, and the sliding rod 47 can slide freely in 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 which is fixed on the sliding rod 47, and the other end is connected to a limit block 46 to limit the excessive stretching of the spring and provide a reset 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 arranged in the lower end 411. The gear 44 is sleeved on the concentric shaft 43 and can rotate freely. In particular, the gear 44 is located between the first rack 48 and the slot 42. Such a design enables the rotation of the gear 44 to simultaneously affect the first rack 48 and the second rack 54 that can mesh 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 realizing the linkage between the two. The lower end 411 of the first slot 41 is flush with the lower end of the second slot 51. Such a design ensures the alignment and smooth fit of the two during assembly.

[0026] In actual operation, when the position of the aluminum alloy decorative curtain panel 5 needs to be installed or adjusted, the sliding rod 47 can be operated (for example, manually pushed or driven by other mechanical devices) so that the sliding rod 47 slides outward from the inside of the first slot 41, and 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, and then 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 drives the gear 44 to rotate, and then drives the second rack 54 to move. As the second rack 54 moves, it will gradually get stuck 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 realizes the functions of automatic adjustment and stable combined installation through the engagement of the gear 44 and the first rack 48, the second rack 54 and the reset action of the spring, thereby enhancing the stability and reliability of the overall structure.

[0027] In another technical solution, a mounting groove 55 is provided on the aluminum alloy decorative curtain panel 5 and corresponds to the insertion position of the glass curtain wall 6. The mounting groove 55 is provided in the vertical direction of the aluminum alloy decorative curtain panel 5. A pair of clamping plates 550 are relatively provided at the opening of the mounting 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 at the edge of the glass curtain wall 6 and corresponds to the mounting groove 55. A pair of second connecting members 8 are provided at the upper and lower ends of the inner side of the mounting groove 55. Each second connecting member 8 includes: A support plate 81 connected to the mounting groove 55, wherein one end of the support plate 81 is fixedly connected to the mounting groove 55, and the other end of the support plate 81 extends in the mounting groove 55 along a horizontal direction; a pair of support springs 82, one end of which is connected to the top end of the support plate 81; The movable plate 83 includes a connecting end 831, a clamping portion 832 and a sliding end 833. The connecting end 831 is connected to the other end of the pair of supporting springs 82. The clamping portion 832 is clamped in the gap between the pair of clamping plates 550. The sliding end 833 contacts the inner wall of the mounting groove 55 and slides in the mounting groove 55 along the length direction thereof as the pair of supporting springs 82 are compressed or extended. The insert 61 on the glass curtain wall 6 is inserted between a pair of second connecting members 8 .

[0028] In the above embodiment, the aluminum alloy decorative curtain panel 5 is designed to have a high degree of aesthetics and structural strength, and its surface is specially treated to ensure corrosion resistance and enhance the overall decorative effect. A mounting groove 55 extending in the vertical direction is provided at the predetermined position of the aluminum alloy decorative curtain panel 5, i.e., the area where the glass curtain wall 6 is to be inserted. A pair of clamps 550 are arranged at the opening of the mounting groove 55 along the length direction of the aluminum alloy decorative curtain panel 5. A small gap 551 is formed between the pair of clamps, providing space for subsequent snap-in connection. The edge of the glass curtain wall 6 is specially equipped with an insert 61. The shape and size of the insert 61 are designed according to the structure of the mounting groove 55 to ensure that it can be tightly and firmly inserted into the mounting groove 55. A pair of second connecting members 8 are respectively installed at the upper and lower ends of the inner side of the mounting groove 55. Each second connecting member 8 is composed 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 in the mounting groove 55 in the horizontal direction, providing a solid foundation for the subsequent spring support; a pair of support springs 82, one end of which is closely connected to the top of the support plate 81, and the selection of the support spring 82 must ensure sufficient elasticity and maintain stable performance during long-term use; a moving plate 83, which is composed of a connecting end 831, a clamping portion 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 spring. The clamping portion 832 is cleverly designed to be able to clamp in the gap between a pair of clamping plates 550, which is the key to achieving the clamping connection. The sliding end 833 contacts the inner wall of the installation groove 55 . As the support spring 82 is compressed or extended, the movable plate 83 can slide in the installation groove 55 along its length direction, thereby achieving a firm clamping of the insert 61 .

[0029] When the insert 61 on the glass curtain wall 6 is inserted into the installation groove 55, it will be inserted into the installation groove 55 along the end surface of the movable plate 83. As the insert 61 continues to go deeper, it will push the sliding end 833 of the movable plate 83, so that the movable plate 83 moves to the upper and lower ends of the installation groove 55 respectively under the action of the support spring 82. When the insert 61 is fully inserted into place, 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, thereby realizing a stable connection between the glass curtain wall 6 and the aluminum alloy decorative curtain plate 5.

[0030] In another technical solution, a buffer member 9 is provided between the stone curtain walls 4 of two adjacent segmented building curtain wall structures, and the buffer member 9 includes: Bracket 91, which is a double L-shaped structure, the bracket 9 is fixed on the keel frame; a pair of first buffer blocks 92, which are elastically connected to the vertical side portions of the bracket 9; A pair of second buffer blocks 93 are elastically connected to the lateral sides of the bracket 9 .

[0031] In the above technical solution, the bracket 91 is designed as a double L-shape, which not only ensures the stability of the bracket 91, but also facilitates 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, to ensure that the buffer block can cover all possible displacement directions. The bracket 91 is firmly mounted on the keel frame by bolts or other fasteners to ensure that it can remain stable 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 side and the horizontal side of the bracket 91, respectively. The pair of first buffer blocks 92 are made of highly elastic materials, such as rubber, polyurethane, etc., and have good compressibility and recovery. 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 angle of the stone curtain wall 4 are respectively against the first buffer block 92 and the second buffer block set at the position, which can provide effective buffering when the stone curtain wall 4 undergoes vertical micro displacement due to wind pressure, thermal expansion and contraction, etc., to prevent direct contact and collision between the stone curtain walls. The second buffer blocks 93 are elastically connected to the lateral sides of the bracket 91, that is, the two horizontal right-angled sides of the bracket 91. These buffer blocks are also made of highly elastic materials and are connected to the bracket 91 through elastic connectors. They exist to cope with the possible lateral displacement of the stone curtain wall 4, and also play a role in protecting the stone curtain wall and reducing collision and friction.

[0032] In actual application, when two adjacent stone curtain walls 4 are slightly displaced due to external factors (such as wind, temperature, etc.), the first buffer block 92 and the second buffer block 93 will absorb the energy brought by the displacement respectively, and slow down the interaction force between the stone curtain walls through elastic deformation, thereby effectively preventing the stone curtain walls from being damaged or broken due to direct collision. This design not only improves the overall stability and durability of the curtain wall system, but also reduces the cost of maintaining or replacing damaged stones.

[0033] In another technical solution, an elastic extrusion piece is arranged inside the clamping part 73. By arranging the elastic extrusion piece inside the clamping part 73, on the one hand, the metal clamping part 73 is prevented from damaging the glass curtain wall 6, and on the other hand, through the characteristics of the elastic extrusion piece, a stable clamping connection is achieved, and the slight size change of the clamped part or the slight deviation during the assembly process can be adapted to a certain extent, thereby improving the flexibility and reliability of assembly. The elastic extrusion piece is made of rubber, silicone or other materials with high elastic restoring force. The shape and size of the elastic extrusion piece match the groove inside the clamping part 73 to ensure that the two can fit closely. When the clamping part 73 contacts the glass curtain wall 6, the elastic extrusion piece will be subjected to a certain amount of extrusion, thereby generating elastic deformation. This deformation not only helps to firmly clamp the glass curtain wall 6 in the clamping part 73, but also can absorb the impact force during the assembly process to a certain extent, reducing the damage of the glass curtain wall 6 caused by improper assembly or material deformation.

[0034] In another technical solution, the embedded parts are 500×100×6 angle steels, which are embedded in the main body 1 of the building wall. The columns are connected and fixed to the embedded parts by bolts, and anti-corrosion gaskets are provided between the bolts and the embedded parts. The embedded parts are made of angle steels of 500×100×6. Angle steels of this specification have sufficient strength and rigidity to withstand the vertical and horizontal loads imposed by the curtain wall system. During the manufacturing process of the embedded parts, it is necessary to ensure that the material meets the relevant standards, such as high-quality carbon structural steels such as Q235B or Q345B, to ensure that they have good mechanical properties and corrosion resistance. Anti-corrosion gaskets are provided between the bolts and the embedded parts to improve the durability and service life of the bolts and embedded parts.

[0035] The present invention also provides a construction method of a segmented building curtain wall structure, which comprises the following steps: Step 1: measure and lay out 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 building wall 1, and then fix the beams 3 between adjacent columns 2 through angle aluminum and bolts according to the installation positions of a pair of stone curtain walls 4; Step 2, fix a pair of stone curtain walls 4 on the beam 3 by the back bolt method, pull the sliding rod 47 in the first slot hole 41 in the stone curtain wall 4 so that the sliding rod 47 slides outward along the inner side of the first slot hole 41 to the top of the first slot hole 41, so that the telescopic spring 45 is in a stretched state, and then the aluminum alloy decorative curtain panel 5 is attached to the outer side of the stone curtain wall 4, so that the second rack 54 is attached to the outer side of the gear 44. At this time, release the sliding rod 47, and the sliding rod 47 is reset by the elastic force of the telescopic spring 45, thereby driving the first rack 48 to move, and the movement of the first rack 48 drives the gear 44 to rotate, and the rotation of the gear 44 drives the second rack 54 to move, thereby driving the second rack 54 to snap into the slot 42 to realize the installation of the stone curtain wall 4 and the aluminum alloy decorative curtain panel 5, and repeat the above operation to complete the installation of a pair of aluminum alloy decorative curtain panels 5; Step 3: fix the insert 61 on the edge of the glass curtain wall 6 corresponding to the mounting groove 55, insert the insert 61 into the mounting groove 55, and clamp it between the pair of second connecting members 8, adjust the mounting position of the pair of second connecting members 8 through elasticity and stabilize it, so that the left and right ends of the glass curtain wall 6 are respectively mounted with the pair of aluminum alloy decorative curtain panels 5; Step 4: fix the vertical portion 71 of the first connecting member 7 to the corresponding position of the stone curtain wall 4, and clamp the upper and lower ends of the glass curtain wall 6 through the clamping portion 73 of the first connecting member 7, wherein the arc-shaped portion 72 extends all the way to the connection between the glass curtain wall and the pair of aluminum alloy decorative curtain panels 5, and covers the corresponding position of the connection gap between the two, so as to prevent 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, but rush out through the curvature of the arc-shaped portion, and transition to the arc-shaped portion 72 of the pair of aluminum alloy decorative curtain panels 5, and then connect and fix with the pair of aluminum alloy decorative curtain panels 5 through connecting members (such as rivets, screws and nuts).
