Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, and in particular to a glass-aluminum composite curtain wall connection structure. Background Technology

[0002] With the development of modern building technology, curtain walls, as the outer cladding of buildings, not only need to have good decorative effects, but also need to meet the requirements of high strength and high stability. At present, glass curtain walls and aluminum panel curtain walls are the two most widely used forms. In order to enrich the visual effect of building facades, glass curtain walls and aluminum panel curtain walls are usually combined and installed to form glass-aluminum panel composite curtain walls.

[0003] However, because composite curtain walls combine the technologies of glass curtain walls and aluminum panel curtain walls, their connection structures are usually quite complex. This increases the difficulty of on-site construction, the workload of workers, and prolongs the construction period. Furthermore, most aluminum panel curtain wall components use integral panels, which are inconvenient to transport and install and difficult to adapt to buildings of different sizes. In addition, traditional composite curtain wall connection structures require the pre-embedding of complex iron parts during concrete pouring. Once the concrete slab is completed, the space for subsequent installation and adjustment of connectors is small, resulting in a low tolerance for construction errors and further increasing the difficulty of construction. Moreover, complex transition parts are often required at the junction of glass and aluminum panels. Glass installation usually requires large equipment for overall hoisting, and the on-site sealing process is complex, further increasing the difficulty of construction and reducing construction efficiency.

[0004] Therefore, it is necessary to improve the existing glass-aluminum composite curtain wall connection structure. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a glass-aluminum composite curtain wall connection structure that reduces the workload of workers, lowers the construction difficulty, facilitates and speeds up construction, and helps improve construction efficiency.

[0006] To achieve the above-mentioned technical effects, the technical solution of the present invention is: a glass-aluminum composite curtain wall connection structure, comprising: A concrete slab is spaced out and fixedly installed along the vertical direction.

The sealing cap is disposed on the end of the connecting profile and is threadedly connected to the positioning bolt. The positioning bolt seals through the side wall of the mating groove.

[0011] Preferably, in order to achieve stable support for the aluminum-plastic groove and reduce the deformation of the profile, the docking assembly further includes a threaded support tube and a support bolt. The support tube and the support bolt respectively penetrate the side walls on both sides of the cavity. The support tube is located between the two side walls of the docking groove and abuts against the upper side wall.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figures 1-18 As shown, a glass-aluminum composite curtain wall connection structure includes: A concrete slab 1 is spaced out and fixedly installed along the vertical direction. The outer periphery of the concrete slab 1 includes a mounting surface 11. A steel bar 12 is protruding from the mounting surface 11 and is arranged horizontally in parallel along its length direction. The axial direction of the steel bar 12 is perpendicular to the mounting surface 11. The connecting component 2 is distributed at intervals along the length of the mounting surface 11, including a connecting profile 21 extending in the vertical direction and a connecting nut 22 threadedly engaged with the reinforcing bar 12. The connecting profile 21 is fixedly connected to the mounting surface 11 through the reinforcing bar 12 and the connecting nut 22. Aluminum plate assembly 3 is connected one-to-one to the side of connecting assembly 2 away from the mounting surface 11, including a number of aluminum-plastic grooves 31 that extend and are distributed along the vertical direction and whose groove openings face away from the mounting surface 11. Adjacent aluminum-plastic grooves 31 are fitted with a gap and connected by splicing unit 32. The mating component 4 is disposed between the two ends of the aluminum plate component 3 and the two ends of the corresponding connecting component 2, and is used to fix the aluminum plate component 3 to the connecting component 2; The curtain wall assembly 5 is disposed between two adjacent aluminum panel assemblies 3, and includes horizontal bars 51 distributed in the vertical direction and extending in the horizontal direction, glass units 52 disposed between adjacent horizontal bars 51, and fixing bars 53 disposed between the two ends of adjacent horizontal bars 51. The side of the horizontal bar 51 adjacent to the glass unit 52 is provided with a groove 511 extending along the length of the horizontal bar 51 and sealingly connected to the glass unit 52. The two ends of the fixing bar 53 are connected to the ends of the adjacent horizontal bars 51, and the fixing bar 53 is fixedly connected to the aluminum-plastic groove 31 by self-tapping screws 54.

[0020] In the connection structure of the present invention, the concrete slab 1 is horizontally arranged, and the mounting surface 11 of the concrete slab 1 is used to install the composite curtain wall composed of glass curtain wall and aluminum panel curtain wall. The construction is divided into three stages. In the first stage, the connecting component 2 is connected by the protruding steel bar 12 on the mounting surface 11. In the second stage, the aluminum panel component 3 is installed on the side of the connecting component 2 facing away from the mounting surface 11. In the third stage, the curtain wall component 5 is installed sequentially from bottom to top between two adjacent aluminum panel components 3, thereby completing the connection structure combination of aluminum panel and glass.

[0021] More specifically, in the first stage, the connecting profile 21 is fastened to the mounting surface 11 of the concrete slab 1 by connecting the connecting nut 22 and the reinforcing bar 12. In the second stage of construction, an aluminum-plastic channel 31 is selected, and its end is connected to the top of the connecting component 2 through the butt joint 4. Then, the end of the aluminum-plastic channel 31 is connected to other aluminum-plastic channels 31 through the splicing unit 32, so that each aluminum-plastic channel 31 extends vertically and is distributed in sequence until the bottom of the last aluminum-plastic channel 31 is connected to the bottom of the connecting component 2 through the butt joint 4, thereby completing the connection of an aluminum plate component 3. Using the above method, according to the number of connecting components 2, multiple aluminum-plastic channels 31 are connected from top to bottom on the side of the connecting component 2 away from the mounting surface 11 through the splicing unit 32, and the top of the top aluminum-plastic channel 31 and the bottom of the bottom aluminum-plastic channel 31 are respectively connected to the two ends of the corresponding connecting component 2 through the connecting butt joint 4, thereby completing the installation of each aluminum plate component 3.

[0022] After all aluminum panel components 3 are installed, the third stage begins, which involves installing curtain wall components 5 between adjacent aluminum panel components 3. Specifically, during installation, horizontal bars 51 and glass units 52 are installed sequentially from bottom to top and spaced apart. First, the position of the horizontal bars 51 is pre-fixed. A positioning support device that can be easily removed can be set below the pre-fixed horizontal bars 51. The horizontal bars 51 are then placed horizontally on the positioning support device, ensuring that the horizontal bars 51 are horizontal and that both ends are respectively attached to the two adjacent aluminum-plastic grooves 31. The glass units 52 are then inserted into the grooves 511 of the horizontal bars 51. Afterward, the horizontal bars 51 are installed on top of the glass units 52, so that the bottom grooves 511 of the higher horizontal bars 51 are embedded into the top of the glass units 52. The upper and lower horizontal bars are then... After the ends of the strip 51 are connected to the two ends of the two fixing strips 53 respectively, self-tapping screws 54 are screwed into the fixing strips 53 so that the self-tapping screws 54 are screwed into the side of the aluminum-plastic groove 31 adjacent to the mounting surface 11, thereby fixing the two horizontal strips 51. Then the positioning support device can be removed, and the glass unit 52 and the horizontal strip 51 are installed sequentially from bottom to top. The two ends of the fixing strip 53 are connected to the two ends of the adjacent horizontal strip 51, and the fixing strip 53 is locked between the adjacent aluminum-plastic grooves 31 by the self-tapping screws 54, so that the horizontal strips 51 and the glass unit 52 are distributed sequentially from bottom to top, and the top and bottom ends of the glass unit 52 are located in the two grooves 511 of the adjacent horizontal strips 51, thus completing the installation of the glass-aluminum composite curtain wall.

[0023] Compared with existing technologies, the glass-aluminum composite curtain wall connection structure of the present invention has the following advantages: First, the aluminum plate assembly 3 of the present invention is spliced ​​on site along the vertical direction using aluminum-plastic groove 31 and splicing unit 32. The curtain wall assembly 5 is spliced ​​with glass unit 52 through horizontal bar 51. The modular bottle design transforms the complex overall installation into standardized unit bottle, which significantly reduces construction difficulty and transportation costs, reduces the workload of construction workers, and helps to improve construction efficiency. Secondly, the curtain wall component 5 adopts a bottom-up installation process. The horizontal bar 51 is pre-positioned to facilitate the placement of the glass unit 52. Then the horizontal bar 51 is installed. The groove 511 is used to achieve a sealed clamping of the top and bottom of the glass unit 52. The end of the fixing bar 53 is connected to the end of the adjacent horizontal bar 51 and locked to the aluminum-plastic groove 31 by the self-tapping screw 54. In this way, the glass unit 52 is installed in an orderly manner, and a firm connection between the glass unit 52 and the aluminum-plastic groove 31 is achieved. Finally, the threaded connection between the reinforcing bar 12 and the connecting nut 22 facilitates the installation of the connecting profile 21, eliminating the need to pre-embed large components during the concrete pouring stage. This reduces reliance on civil engineering construction, simplifies construction, and allows for flexible installation, further reducing construction difficulty and facilitating rapid construction.

[0024] To further facilitate transportation, construction, and installation, the connecting component 2 of this invention includes multiple connecting profiles 21, which are distributed and extended along the vertical direction and connected sequentially. The specific structure of the connecting component 2 is as follows: Figure 5 and Figure 6 As shown, the connecting profile 21 includes a profile body with a rectangular cross-section and side wings 212 integrally formed on both sides of the profile body and along the same length direction. The profile body has a hollow structure, giving the connecting profile 21 a rectangular cavity 211. A connecting plate 23, a connecting block 24, and a mating profile 25 are provided between two adjacent connecting profiles 21. The mating profile 25 has the same cross-sectional shape and size as the connecting profile 21. The connecting block 24 is fixedly and sealingly inserted through the inner side of the mating profile 25. The two ends of 5 are fitted with the two end faces of the adjacent connecting profile 21. The two ends of the connecting block 24 are inserted into the cavity 211 of the adjacent connecting profile 21. The connecting plate 23 is set between the adjacent connecting profiles 21. The connecting plate 23 is a bent plate. The connecting plate 23 is fitted with the profile body of the adjacent connecting profile 21 away from the mounting surface 11 and the side of the side wing 212 away from the mounting surface 11. The four corners are fixedly connected to the two ends of the connecting profile 21 by the mating nut 26 and the mating screw 27.

[0025] With the above structure, the connecting component 2 adopts a modular design, which facilitates transportation and construction. On-site construction allows for the sequential connection of each connecting profile 21 to form the connecting component 2 for the installation of the aluminum plate assembly 3. Specifically, after the mating profile 25 and the connecting block 24 are pre-welded together, the connecting profile 21 is kept vertical. Then, the connecting block 24 is inserted into the cavity 211 of the connecting profile 21, so that its bottom end is sealed against the circumferential inner wall of the cavity 211 at the top of the connecting profile 21. After the mating profile 25 abuts against the top of the connecting profile 21, another connecting profile 21 is vertically inserted into the top of the connecting block 24, so that the circumferential inner wall of the bottom of the cavity 211 of the connecting profile 21 is sealed against the connecting block 24, and the bottom surface of the connecting profile 21 is against the top surface of the mating profile 25. In this way, the two connecting profiles 21 are connected. After the projections of the two connecting profiles 21 along the same length direction and on the horizontal plane coincide, the connecting plate 23 is placed on the position where the two connecting profiles 21 are close to each other. The connecting screws 27 are inserted at the four corners of the connecting plate 23, so that the rod of the connecting screw 27 passes through the side wing 212 and the connecting plate 23 in sequence with its back to the mounting surface 11. Then the connecting nut 26 is screwed on, so that the two connecting profiles 21 are precisely connected through the connecting profile 25 and the connecting block 24, while the adjacent connecting profiles 21 are connected by the connecting screw 27, the connecting nut 26 and the connecting plate 23. After the connecting profiles 21 are connected in sequence to form the connecting assembly 2, the connecting assembly 2 is placed against the concrete slab 1, so that the side wing 212 is sleeved on the outside of the reinforcing bar 12. Then the connecting nut 22 is screwed into the outside of the reinforcing bar 12, so that the connecting assembly 2 is locked and fixed on the mounting surface 11 of the concrete slab 1.

[0026] A further improvement is that the aluminum-plastic channel 31 is formed by bending aluminum-plastic sheet multiple times. The aluminum-plastic channel 31 has two inner extension sections 311 that extend vertically into the inside of its own channel and are arranged side by side. A horizontal axis 33 with an axial direction parallel to the length direction of the mounting surface 11 is fixed between the two inner extension sections 311. The horizontal axes 33 corresponding to the two ends of the adjacent aluminum-plastic channels 31 that are close to each other are connected by splicing unit 32. The horizontal axis 33 located at the end position in the aluminum plate assembly 3 is fixedly connected to the aluminum plate assembly 3 by the docking assembly 4.

[0027] In this invention, the aluminum-plastic channel 31 is formed by bending a rectangular aluminum-plastic plate multiple times. After installation, the opening of the aluminum-plastic channel 31 faces the connecting component 2. The aluminum-plastic channel 31 also has an inner extension section 311 formed by bending multiple times. The inner extension section 311 is located inside the opening of the aluminum-plastic channel 31 and extends inward. By fixing a horizontal shaft 33 between the two ends of the inner extension section 311, the horizontal shaft 33 is connected to the splicing unit 32, which facilitates the sequential connection of multiple aluminum-plastic channels 31 to form an aluminum plate assembly 3. At both ends of the aluminum plate assembly 3, that is, at the two ends of the two aluminum-plastic channels 31 that are far apart from each other, the corresponding two horizontal shafts 33 are connected to the connecting component 2 through the docking component 4, thereby realizing the fixed connection between the aluminum plate assembly 3 and the connecting component 2.

[0028] After adopting the above structure, during installation, one of the aluminum-plastic channels 31 is selected and kept vertical. The horizontal axis 33 at its top is connected to the top of the connecting profile 21 through the docking component 4. Then, another aluminum-plastic channel 31 is set at the bottom of the aluminum-plastic channel 31. The horizontal axis 33 at the bottom of the upper aluminum-plastic channel 31 is connected to the horizontal axis 33 at the top of the lower aluminum-plastic channel 31 through the splicing unit 32, thereby realizing the connection of adjacent aluminum-plastic channels 31. The aluminum-plastic channels 31 are connected by the above method, and finally an aluminum plate assembly 3 extending in the vertical direction is formed. Then, the horizontal axis 33 at the bottom of the aluminum-plastic channel 31 at the bottom of the aluminum plate assembly 3 is connected to the bottom end of the bottom connecting profile 21 through the docking component 4. Finally, the two ends of the aluminum plate assembly 3 are fixedly connected to the two ends of the connecting component 2 through two docking components 4, which facilitates the installation of the curtain wall assembly 5 between adjacent aluminum plate assemblies 3.

[0029] A further improvement is that the horizontal shaft 33 includes a horizontal screw 331 located between two inner extension sections 311 and a horizontal screw tube 332 threadedly connected to both ends of the horizontal screw 331 and corresponding one-to-one with the two inner extension sections 311. The horizontal screw tube 332 is sealed and passes through the inner side of the corresponding inner extension section 311 and abuts against the inner wall of the aluminum-plastic groove 31. A limiting protrusion 3321 is provided on the horizontal screw tube 332, and the limiting protrusions 3321 of the two horizontal screw tubes 332 abut against the opposite sides of the two inner extension sections 311 respectively.

[0030] With the above structure, it is convenient to fix the two horizontal shafts 33 to the two ends of the inner side of the aluminum-plastic groove 31, respectively. More specifically, if Figure 10As shown, the inner wall of the aluminum-plastic groove 31 also includes an abutment wall 314 that is directly opposite to the two inner extension sections 311. The ends of the two inner extension sections 311 are provided with coaxial circular holes for the transverse screw tube 332 to pass through in a sealed manner. The length of the transverse screw 331 is less than the distance between the two inner extension sections 311. The two transverse screw tubes 332 have the same length and the sum of their lengths is the same as the length of the transverse screw 331. The length of the transverse screw 332 is greater than the distance between the inner extension section 311 and the corresponding abutment wall 314. When connecting the aluminum-plastic channel 31 to the connecting component 2 and other aluminum-plastic channels 31, a horizontal shaft 33 is pre-installed inside the aluminum-plastic channel 31. During installation, the two horizontal screw tubes 332 are first rotated close to each other so that the two horizontal screw tubes 332 are located between the two ends of the horizontal screw 331. The horizontal screw tubes 331 are then placed between the round holes of the two inner extension sections 311. Then, the two horizontal screw tubes 332 are rotated in opposite directions so that the two horizontal screw tubes 332 are moved away from each other and seal their corresponding round holes. Finally, they abut against the abutment wall 314. At the same time, the limiting protrusion tube 3321 abuts against the side of the inner extension section 311 away from the abutment wall 314. Finally, the horizontal shaft 33 is fixedly installed at both ends of the aluminum-plastic channel 31, which facilitates the connection of the aluminum-plastic channel 31 and the connection between the aluminum-plastic channel 31 and the connecting component 2.

[0031] A further improvement is that a reinforcing plate 312 is provided inside the aluminum-plastic channel 31, which is distributed along its length and is sealed to its inner wall. The reinforcing plate 312 is fixedly connected to the aluminum-plastic channel 31 by a reinforcing bolt 313, and the head of the reinforcing bolt 313 is located on the side of the aluminum-plastic channel 31 adjacent to the mounting surface 11.

[0032] Specifically, such as Figure 11 As shown, a reinforcing plate 312 is provided inside the aluminum-plastic groove 31 along its length. The side of the reinforcing plate 312 adjacent to the mounting surface 11 also has a strip-shaped notch, which matches the inner extension section 311. This facilitates the reinforcing plate 312 sliding into the aluminum-plastic groove 31 from its end, ensuring a tight seal between the inner wall of the notch and the inner extension section 311. Furthermore, after the reinforcing plate 312 is in contact with the inner wall of the aluminum-plastic groove, the end of the reinforcing plate 312 adjacent to the mounting surface 11 protrudes outside the aluminum-plastic groove 31, facilitating control of the reinforcing plate 312 along the aluminum-plastic groove 31. Before the aluminum-plastic channel 31 is formed by bending the aluminum-plastic sheet multiple times, multiple mounting holes can be pre-drilled. When the reinforcing plate 312 slides to the corresponding mounting hole position, the reinforcing bolt 313 is screwed in, so that the head of the reinforcing bolt 313 abuts against the side of the aluminum-plastic channel 31 facing away from the mounting surface 11, thereby completing the fixation of the position of the reinforcing plate 312. The reinforcing plate 312 helps to enhance the structural strength of the aluminum-plastic channel 31 and prevent it from being bent and deformed. After the reinforcing plates 312 are fixedly installed, the horizontal shaft 33 is fixed at both ends of the aluminum-plastic channel 31 in the above manner.

[0033] A further improvement is that the splicing unit 32 includes a splicing groove 321, a splicing block 322, and a splicing bolt 323. The splicing groove 321 is fitted between two inner extension sections 311, and its inner bottom wall abuts against the upper transverse threaded tube 332. Both sides of the splicing block 322 are fitted with the inner sidewall of the splicing groove 321, and both ends are fitted with the two inner extension sections 311. The top surfaces of both ends of the splicing block 322 are respectively fitted with the lower part of the two limiting protrusions 3321. The shank of the splicing bolt 323 passes through the sidewall of the splicing groove 321 and is threadedly connected to the splicing block 322. Furthermore, in two adjacent aluminum-plastic grooves 31, the splicing block 322 is located on the reinforcing plate 312 at the top position of the lower aluminum-plastic groove 31.

[0034] With the above structure, when splicing two adjacent aluminum-plastic channels 31 through splicing unit 32, the upper aluminum-plastic channel 31 is already fixed. The lower aluminum-plastic channel 31 is moved to directly below the upper aluminum-plastic channel 31, keeping their coaxial centerlines and their horizontal projections overlapping. Then, a splicing block 322 is placed on the reinforcing plate 312 at the top of the lower aluminum-plastic channel 31, with both ends attached between the two inner extensions 311, and the top surfaces of both ends attached to the bottom of the two limiting protrusions 3321. The splicing slot 321 is then pressed downwards onto the transverse screw 3 corresponding to the bottom position of the upper aluminum-plastic channel 31. 31 is such that the two ends of the splicing groove 321 are attached to the two limiting protrusions 3321, while the inner walls on both sides of the groove are attached to the splicing block 322. Then, the splicing bolt 323 is screwed in, so that the splicing groove 321, the splicing block 322 and the splicing bolt 323 are combined to form a closed loop frame. The inner walls of the upper and lower ends of the closed loop frame respectively abut against the transverse screws 331 corresponding to the two aluminum-plastic grooves 31 at their close ends. This allows the lower aluminum-plastic groove 31 to be suspended below the upper aluminum-plastic groove 31. Then, in the above manner, the aluminum-plastic grooves 31 are spliced ​​below each aluminum-plastic groove 31 from top to bottom.

[0035] A further improvement is that a positioning block 324 is provided between the reinforcing plates 312 corresponding to the close ends of the adjacent aluminum-plastic grooves 31. The positioning block 324 is in contact with the inner wall of the two aluminum-plastic grooves 31 and is in contact with the upper part of the reinforcing plate 312 located below. The splicing bolt 323 is threadedly connected to the positioning block 324.

[0036] After adopting the above structure, when splicing two adjacent aluminum-plastic grooves 31, such as Figure 9 and Figure 15As shown, in addition to placing splicing blocks 322 on the reinforcing plate 312 corresponding to the top of the lower aluminum-plastic channel 31, positioning blocks 324 are also placed. The positioning blocks 324 are columnar structures that fit against the inner wall of the aluminum-plastic channel 31. When two adjacent aluminum-plastic channels 31 are spliced, the bottom of the positioning blocks 324 is inserted into the top of the lower aluminum-plastic channel 31, and the top of the positioning blocks 324 is inserted into the bottom of the upper aluminum-plastic channel 31. On the one hand, this ensures that the projections of two adjacent aluminum-plastic channels 31 on the horizontal plane are completely consistent, improving splicing accuracy and avoiding deviations in the horizontal direction. On the other hand, it can reinforce the end positions of two adjacent aluminum-plastic channels 31, further enhancing the connection strength of the adjacent aluminum-plastic channels 31. In addition, the positioning blocks 324 are also threadedly connected to the splicing bolts 323, increasing the insertion depth of the splicing bolts 323 and ensuring the connection strength between the splicing bolts 323 and the aluminum-plastic channel 31, thereby enhancing the structural strength of the aluminum plate assembly 3.

[0037] A further improvement is that the connecting profile 21 has a cavity 211 extending along its own length and side wings 212 disposed on both sides of the cavity 211. The reinforcing bar 12 passes through the side wings 212 and is connected to the connecting nut 22. The docking assembly 4 includes a docking groove 41, a sealing cap 42 and a positioning bolt 43. The two ends of the docking groove 41 are fitted with two inner extensions 311 and the inner bottom wall abuts against the corresponding transverse screw 331. The side wall of the docking groove 41 passes through the side wall of the cavity 211 in a direction perpendicular to the mounting surface 11. The sealing cap 42 is placed on the end of the connecting profile 21 and is threadedly connected to the positioning bolt 43. The positioning bolt 43 seals through the side wall of the docking groove 41.

[0038] Specifically, such as Figure 6 , Figure 14 As shown, when connecting the two ends of the aluminum plate assembly 3 to the two ends of the connecting assembly 2 through two docking components 4, strip holes are pre-drilled on the top of the profile body of the connecting profile 21 at the top position and the bottom of the profile body of the connecting profile 21 at the bottom position in the connecting assembly 2. Then, an aluminum-plastic channel 31 is connected to the connecting profile 21 at the top position through a docking component 4. During connection, a docking groove 41 is inserted into the outside of the horizontal screw 331 at the top of the aluminum-plastic channel 31, so that the docking groove 41 is kept horizontal while its groove opening faces the connecting profile 21. After the groove opening of the docking groove 41 passes through the strip hole, it abuts against the inner wall of the cavity 211 near the mounting surface 11. A sealing cap 42 is installed on the top of the top connecting profile 21, so that it covers the top of the cavity 211 of the connecting profile 21. Then, a positioning bolt 43 is screwed in, so that the shank of the positioning bolt 43 is threadedly connected to the sealing cap 42, sealing the upper and lower side walls of the docking groove 41, thereby completing the installation of the top aluminum-plastic channel 31.

[0039] After the top aluminum-plastic channel 31 is installed, each aluminum-plastic channel 31 is installed sequentially through the splicing unit 32 to form the aluminum plate assembly 3. Then, a mating groove 41 is installed outside the bottom horizontal screw 331 of the bottom aluminum-plastic channel 31. The mating groove 41 passes through the strip hole at the bottom end of the bottom connecting profile 21 and abuts against the inner wall of the cavity 211. Then, a sealing cover 42 is placed on the bottom end of the cavity 211 and a positioning bolt 43 is screwed in. Thus, the two ends of the aluminum plate assembly 3 are connected to the two ends of the connecting assembly 2 through the two mating components 4, thereby fixing the aluminum plate assembly 3 to the connecting assembly 2.

[0040] A further improvement is that the docking assembly 4 also includes a threaded support screw tube 44 and a support bolt 45, which respectively penetrate the side walls on both sides of the cavity 211. The support screw tube 44 is located between the two side walls of the docking groove 41 and abuts against the upper side wall.

[0041] After adopting the above structure, after connecting the aluminum plate assembly 3 and the connecting assembly 2 at both ends, a support screw tube 44 and a support bolt 45 are respectively threaded through the side walls at both ends of the profile body, with the axial direction parallel to the length direction of the mounting surface 11. There are two support screw tubes 44, which are integrally connected by a limiting plate. The limiting plate abuts against the inner wall on one side of the profile body, and the head of the support bolt 45 abuts against the inner wall on the other side of the profile body. This achieves a fixed connection between the support screw tube 44 and the support bolt 45, while the support screw tube 44 abuts against the lower side wall of the mating groove 41 located above, thereby supporting the mating groove 41, strengthening the support effect, and preventing the connecting profile 21 from deforming due to excessive weight.

[0042] A further improvement is that a positioning plate 46 is integrally connected to the side of the sealing cover 42 adjacent to the connecting profile 21, and the positioning plate 46 is fitted between the inner wall of the cavity 211 and the end of the mating groove 41.

[0043] After adopting the above structure, while the cavity 211 is covered by the sealing cover 42, the positioning plate 46 can be used to position the sealing cover 42 and the docking groove 41 to prevent horizontal displacement and ensure the precise connection between the connecting component 2 and the aluminum plate component 3.

[0044] A further improvement is that the horizontal bar 51 is provided with a through hole 512 extending along its length direction, and the fixing bar 53 includes a positioning section 531 extending in the vertical direction and a plug-in section 532 fixed at both ends of the positioning section 531. The plug-in section 532 is plugged into the hole 512. The self-tapping screw 54 passes through the positioning section 531 and the side of the aluminum-plastic groove 31 adjacent to the mounting surface 11.

[0045] Specifically, such as Figures 16-18As shown, the horizontal bar 51 is a profile with an integrally formed groove 511 and a socket 512. The groove 511 is used to embed the glass unit 52, while the socket 512 facilitates the insertion of the insertion segment 532 of the fixing bar 53. The fixing bar 53 is formed by an integral connection of a positioning segment 531 and two insertion segments 532 to form a U-shaped structure, which facilitates movement along the axial direction of the socket 512. After the two insertion segments 532 are inserted into the socket 512, the shanks of the self-tapping screws 54 are screwed into the fixing bar 53 in sequence. The positioning section 531 and the aluminum-plastic groove 31 are located on the side of the mounting surface 11, which can lock and fix the position of the fixing strip 53. The fixing strip 53 is fixed at both ends. The end of the fixing strip 53 is inserted into the insertion hole 512 to achieve fixed support for the horizontal bar 51. The two ends of the glass unit 52 are sealed and supported by the groove 511 of the upper and lower horizontal bars 51, thereby achieving the position fastening of the glass unit 52. This facilitates the connection between the glass unit 52 and the horizontal bar 51, reduces the construction difficulty, and helps to improve the construction efficiency.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
