This invention discloses a track-mounted unitized curtain wall system and installation method for indoor installation. The system includes inter-floor support steel frames cantilevered between each floor of the main structure. Multiple unitized panels are installed between adjacent inter-floor support steel frames. Inter-floor stone panels are attached to the exterior side of the inter-floor support steel frames. The inter-floor support steel frames run the entire length of the main structure in the left-right direction. An upper track is provided along the bottom of the inter-floor support steel frame, and a lower track is provided at the top. Each unitized panel has an upper sliding member at the top and a lower sliding member at the bottom. The unitized panel is installed in place by sliding along the lower track using the lower sliding member, which is placed on a small trolley at its bottom. During the sliding process, the upper sliding member on the top of the unitized panel slides within the upper track. After installation, the unitized panel is inserted and fixed to adjacent panels, and the upper sliding member and the lower sliding member are fixedly positioned relative to each other. This invention achieves sliding installation of unitized panels from the interior side of the main structure through a track design.

Description

Technical Field

[0001] This invention relates to a track-mounted unitized curtain wall system capable of indoor installation and its installation method, belonging to the field of unitized curtain walls. Background Technology

[0002] Currently, the conventional installation method for unitized curtain walls involves hanging the unitized panels on the exterior of the main structure. To facilitate outdoor installation of the unitized panels, barriers cannot be installed on the exterior of the main structure. However, in urban areas where construction must be carried out within enclosed spaces created by barriers, removing the barriers would inevitably place extremely high demands on the safety of the construction process, incur high implementation costs, and would significantly impact the external visual landscape. Conversely, if barriers are installed, the unitized panels cannot be hung from the outside.

[0003] The existing indoor installation method for unitized panels is a floor-mounted approach. This method requires the unitized panels to be installed in place in one go, which is difficult to implement. In addition, special structures such as existing structural columns or walls inside the main structure must be avoided during the installation process. In other words, the existing floor-mounted approach cannot be successfully implemented when there are special structures such as existing structural columns or walls inside the main structure.

[0004] Therefore, designing a technical solution that enables convenient installation of unit modules from indoors is an urgent problem to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a track-type unitized curtain wall system and its installation method that can be installed on the indoor side. Through the design of the track, the unit panels can be slidably installed from the indoor side of the main structure. The installation is convenient, easy to implement and low in cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An indoor-mounted, track-mounted, unitized curtain wall system includes an inter-floor support steel frame cantilevered on the main structure between each floor. Multiple unit panels are installed between two adjacent inter-floor support steel frames via a sliding mechanism along a track in the left-right direction. Two adjacent unit panels are interlocked and fixed together. Inter-floor stone panels are hung on the outdoor side of the inter-floor support steel frames, with the surface materials of the inter-floor stone panels facing each other vertically. The inter-floor support steel frames are continuous along the left-right direction on the main structure between floors; the bottom of the inter-floor support steel frames extends along the track... An upper track runs horizontally through the unit, while a lower track runs horizontally through the top of the unit. The top of each unit plate has an upper sliding member, and the bottom has a lower sliding member. The unit plate is installed in place by sliding along the lower track using the lower sliding member, which is placed on a small trolley at its bottom. During the sliding process, the upper sliding member on the top of the unit plate slides within the upper track. After installation, the unit plate is inserted and fixed to adjacent unit plates. The upper sliding member is fixed to the upper track via a limiting bolt, and the lower sliding member is fixed to the lower track via a limiting screw.

[0008] An installation method for the track-mounted unitized curtain wall system capable of indoor installation includes the following steps:

[0009] 1) Install the interlayer support steel frame on each of the aforementioned interlayer main structures;

[0010] 2) A notch is made on the side of the upper track at the bottom of the inter-layer support steel frame facing the room, and the trolley is placed in the lower track at the top of the inter-layer support steel frame;

[0011] 3) Install each of the unit modules one by one, wherein the installation steps for each unit module include:

[0012] 3-1) Using a hoisting device, the unit plate is placed between the upper and lower rails through the gap and onto the small trolley. The unit plate is then pushed so that the upper sliding member and the lower sliding member on the unit plate enter the upper and lower rails respectively.

[0013] 3-2) After continuing to push the unit plate to the installation position, remove the small trolley so that the sliding part at the bottom of the unit plate is directly placed on the lower track;

[0014] 3-3) Insert and fix the unit plate to another adjacent unit plate;

[0015] 3-4) The upper sliding member of the unit plate is fixed to the upper rail by the limiting bolt, and the lower sliding member is fixed to the lower rail by the limiting screw;

[0016] 4) Hang the interlayer stone panels on the interlayer support steel frames on each of the interlayer main structures;

[0017] 5) Complete the installation of the track-type unitized curtain wall system.

[0018] The advantages of this invention are:

[0019] This invention, through the design of a transverse track, enables the sliding installation of unit panels from the interior side of the main structure. This results in high installation efficiency and low cost, and is not limited by existing structural columns or walls within the main structure. The installed curtain wall structure is safe, stable, and reliable. This invention avoids impacting the external landscape during construction. Barriers can be installed on the exterior side of the main structure according to project requirements, ensuring construction safety. It can be widely applied to new construction projects, renovation projects, and confidential projects. Attached Figure Description

[0025] like Figures 1 to 5As shown, this invention proposes a track-mounted unitized curtain wall system that can be installed indoors. It includes inter-floor support steel frames 10 cantilevered on the main structure 90 between each floor. The inter-floor support steel frames 10 serve as the support system for the entire track-mounted unitized curtain wall system. Multiple unit panels 30 are installed between two adjacent inter-floor support steel frames 10 by sliding left and right along a track in the left-right direction. Two adjacent unit panels 30 are interlocked and fixed together. Inter-floor stone panels 70 are hung on the outdoor side of the inter-floor support steel frames 10. The inter-floor stone panels 70 and the surface materials 35 of the adjacent unit panels 30 are vertically aligned. The inter-floor support steel frames 10 are continuous along the left-right direction on the main structure 90. The bottom of the unit is provided with an upper rail 51 running horizontally, and the top of the interlayer support steel frame 10 is provided with a lower rail 52 running horizontally. The top of the unit plate 30 is provided with an upper sliding member 41, and the bottom of the unit plate 30 is provided with a lower sliding member 43. The unit plate 30 is installed in place by sliding along the lower rail 52 by the lower sliding member 43 placed on the small trolley 80 at its bottom. During the sliding process of the unit plate 30, the upper sliding member 41 at the top of the unit plate 30 slides in the upper rail 51. After the unit plate 30 is installed in place, it is plugged and fixed to the adjacent unit plate 30 (i.e., the previously installed unit plate 30). The upper sliding member 41 is fixed to the upper rail 51 by the limiting bolt 61, and the lower sliding member 43 is fixed to the lower rail 52 by the limiting screw 62.

[0026] like Figure 1 The inter-floor support steel frame 10 includes a steel adapter 14 cantilevered and fixed to the inter-floor main structure 90. A steel column 12 is vertically installed at the cantilever end of the steel adapter 14. The steel column 12 is located on the outdoor side of the inter-floor main structure 90. The lower part of the steel column 12 is connected to one end of a steel diagonal brace 13, and the other end of the steel diagonal brace 13 is connected to a steel connector 17 fixed to a steel crossbeam 11. The steel crossbeam 11 is fixed to the bottom surface of the inter-floor main structure 90. Specifically, along the left-right direction... See, each steel column 12 is spaced apart on the outdoor side of the inter-floor main structure 90. Two adjacent steel columns 12 are welded together by steel connecting beams 15. The inter-floor stone panel 70 is hung on the steel connecting beams 15. The top of each steel column 12 is fixedly installed with a lower rail 52 along the left and right direction via an L-shaped lower connector 54 (such as a steel angle bracket). The bottom of each steel column 12 is fixedly installed with an upper rail 51 along the left and right direction via an L-shaped upper connector 53 (such as a steel angle bracket).

[0027] In practical design, such as Figure 1The steel adapter 14 is preferably designed with an inverted T-shaped cross-section. The steel adapter 14 is fixed to the interlayer main structure 90 via a fixing bolt assembly 16. The steel adapter 14 may be provided with a left-right adjustment elongated hole (not shown in the figure). The fixing bolt assembly 16 includes a fixing bolt, a fixing nut, and a fixing washer with serrations. The serrations on the fixing washer are arranged opposite to the serrations around the left-right adjustment elongated hole of the steel adapter 14, so that the left-right adjustment and positioning of the steel adapter 14 can be realized in the left-right direction by means of the design of the left-right adjustment elongated hole and the serrations.

[0028] like Figure 1 The steel column 12 is fixed to the cantilever end of the steel adapter 14 via the inner and outer locking bolt assembly 18. The steel column 12 may be provided with inner and outer adjustment elongated holes 180. The inner and outer locking bolt assembly 18 includes inner and outer locking bolts, inner and outer locking nuts, and inner and outer locking washers with serrations. The serrations on the inner and outer locking washers are arranged opposite to the serrations around the inner and outer adjustment elongated holes 180 of the steel column 12, so that the inner and outer adjustment and positioning of the steel column 12 can be realized in the inner and outer directions by means of the design of the inner and outer adjustment elongated holes 180 and the serrations.

[0029] like Figure 1 The steel diagonal brace 13 is fixed to the steel connector 17 via the upper and lower locking bolt assembly 19. The steel connector 17 is welded to the steel beam 11, and the steel beam 11 is fixed to the interlayer main structure 90 by means such as embedded parts. The steel connector 17 may be provided with an upper and lower adjustable elongated hole 190. The upper and lower locking bolt assembly 19 includes upper and lower locking bolts, upper and lower locking nuts, and upper and lower locking washers with serrations. The serrations on the upper and lower locking washers are arranged opposite to the serrations around the upper and lower adjustable elongated hole 190 of the steel connector 17, so that the upper and lower adjustment and positioning of the steel diagonal brace 13 can be realized in the upper and lower direction by means of the design of the upper and lower adjustable elongated hole 190 and the serrations.

[0030] like Figures 1 to 3The L-shaped lower connector 54 is composed of a vertical plate and a horizontal plate (not shown in the figure). The vertical plate is fixed to the top of the steel column 12 by a lower vertical fixing bolt assembly 58, and the horizontal plate is fixed to the bottom of the lower track 52 by a lower horizontal fixing bolt assembly 59. The vertical plate may be provided with an up-and-down adjustment elongated hole 580. The lower vertical fixing bolt assembly 58 includes a lower vertical fixing bolt, a lower vertical fixing nut, and a lower vertical fixing washer with serrations. The serrations on the lower vertical fixing washer are arranged opposite to the serrations around the up-and-down adjustment elongated hole 580 of the vertical plate, thereby enabling up-and-down adjustment and positioning of the L-shaped lower connector 54, i.e., the lower track 52, in the vertical direction through the design of the up-and-down adjustment elongated hole 580 and the serrations. The horizontal plate may be provided with an inner and outer adjustment elongated hole (not shown in the figure). The lower transverse fixing bolt assembly 59 includes a lower transverse fixing bolt 591, a lower transverse fixing nut, and a lower transverse fixing washer with serrations. The serrations on the lower transverse fixing washer are arranged opposite to the serrations around the inner and outer adjustment elongated holes of the cross plate. Thus, the design of the inner and outer adjustment elongated holes and the serrations allows for the inner and outer adjustment and positioning of the L-shaped lower connector 54, i.e., the lower track 52, in the inner and outer directions. It should be noted that, on the one hand, the aforementioned adjustment elongated holes are designed to avoid deviation in order to ensure the flatness and straightness of the lower track 52. On the other hand, the lower transverse fixing bolt 591 connecting the cross plate of the L-shaped lower connector 54 to the lower track 52 is a countersunk bolt to ensure that the trolley 80 can pass smoothly within the lower track 52.

[0031] like Figures 1 to 3The L-shaped upper connector 53 is composed of a vertical plate and a horizontal plate (not shown in the figure). The vertical plate is fixed to the bottom of the steel column 12 by an upper vertical fixing bolt assembly 56, and the horizontal plate is fixed to the top of the upper track 51 by an upper horizontal fixing bolt assembly 57. The vertical plate may be provided with an up-and-down adjustment elongated hole 560. The upper vertical fixing bolt assembly 56 includes an upper vertical fixing bolt, an upper vertical fixing nut, and an upper vertical fixing washer with serrations. The serrations on the upper vertical fixing washer are arranged opposite to the serrations around the up-and-down adjustment elongated hole 560 of the vertical plate, thereby enabling up-and-down adjustment and positioning of the L-shaped upper connector 53, i.e., the upper track 51, in the vertical direction through the design of the up-and-down adjustment elongated hole 560 and the serrations. The horizontal plate may be provided with an inner and outer adjustment elongated hole (not shown in the figure). The upper transverse fixing bolt assembly 57 includes an upper transverse fixing bolt 571, an upper transverse fixing nut, and an upper transverse fixing washer with serrations. The serrations on the upper transverse fixing washer are arranged opposite to the serrations around the inner and outer adjustment elongated holes of the cross plate. Thus, the design of the inner and outer adjustment elongated holes and the serrations allows for the inner and outer adjustment and positioning of the L-shaped upper connector 53, i.e., the upper track 51, in the inner and outer directions. It should be noted that, on the one hand, the above-mentioned adjustment elongated holes are designed to avoid deviation in order to ensure the flatness and straightness of the upper track 51. On the other hand, the upper transverse fixing bolt 571 connecting the cross plate of the L-shaped upper connector 53 to the upper track 51 is a countersunk bolt to ensure that the upper sliding member 41 can pass smoothly within the upper track 51.

[0032] In actual production, the upper track 51 and the lower track 52 are made of aluminum alloy.

[0033] like Figure 1 A mounting beam 76 (such as a U-shaped steel) is fixed on the steel connecting beam 15. Multiple lower hooks 72 are fixed on the side of the mounting beam 76 facing the outside along the left and right direction. The side of the interlayer stone panel 70 facing the inside is fixed with a corresponding number of upper hooks 74 corresponding to each lower hook 72. The interlayer stone panel 70 is hung on the interlayer support steel frame 10 by the upper hooks 74 being hooked on the lower hooks 72.

[0034] In actual design, viewed from the top and bottom, one or more interlayer stone panels 70 are hung on the interlayer support steel frame 10. Figure 1 The diagram shows two interlayer stone panels 70 suspended vertically. A cover 36 is horizontally installed between the uppermost interlayer stone panel 70 and the surface material 35 of the unit panel 30 above it. Similarly, a cover 36 is horizontally installed between the lowermost interlayer stone panel 70 and the surface material 35 of the unit panel 30 below it. Typically, the cover 36 is fixed to the frame (top beam 31 or bottom beam 32) of the unit panel 30 via connecting screws 360.

[0035] like Figure 1The steel connecting beam 15 is fixed to the mounting beam 76 by a fastening bolt assembly 71. The steel connecting beam 15 may be provided with an inner and outer adjustment elongated hole (not shown in the figure). The fastening bolt assembly 71 includes a fastening bolt, a fastening nut, and a fastening washer with serrations. The serrations on the fastening washer are arranged opposite to the serrations around the inner and outer adjustment elongated holes of the steel connecting beam 15, so that the inner and outer adjustment elongated holes and the serrations can be used to adjust and position the mounting beam 76 in the inner and outer directions.

[0036] like Figure 1 The lower hook 72 is fixed to the mounting beam 76 by a first bolt assembly 73. The first bolt assembly 73 includes a first bolt, a first nut, and a first washer (not shown in the figure). Similarly, the upper hook 74 is fixed to the interlayer stone panel 70 by a second bolt assembly 75. The second bolt assembly 75 includes a second bolt, a second nut, and a second washer (not shown in the figure).

[0037] like Figure 3 The upper track 51 is a groove with an inverted U-shaped cross section, and the upper sliding member 41 is a profile with a rectangular cross section. The structure is simple and the force transmission is direct. It is preferable that the top of the unit plate 30 is provided with two upper sliding members 41 separately, but of course, there are no restrictions.

[0038] like Figure 2 The lower track 52 is a U-shaped groove, in which a small steel trolley 80 slides. The lower slide member 43 is an inverted U-shaped profile. The two sides of the lower slide member 43 are provided with sliding grooves 431 for locking (or mounting) on ​​the two side walls of the lower track 52. It is preferable that two lower slide members 43 are separately provided at the bottom of the unit plate 30, but this is not a limitation.

[0039] To ensure that the unit plate 30 can slide smoothly in the left and right directions, such as Figure 2 The lower track 52 has semi-circular sliding heads 520 on both sides facing upwards. The groove 431 has a downward opening with a structure that is smaller inside and larger outside, and the shape of the groove is an arc that matches the shape of the sliding head 520. That is, the junction between the groove 431 and the sliding head 520 is designed to be arc-shaped to facilitate the movement of the sliding part 43 of the unit plate 30 into the lower track 52. The groove 431 is deeper than the height of the sliding head 520. This ensures that the sliding part 43 will not fall out of the lower track 52 during the sliding process of the unit plate 30 after it is placed on the trolley 80 (there is still an overlap between the groove 431 and the sliding head 520) and will move smoothly. On the other hand, it ensures that there is sufficient overlap length between the sliding part 43 and the lower track 52 to ensure stable connection after installation.

[0040] like Figure 2 and Figure 3Flexible rubber strips 55 are provided on the inner side of the upper track 51 and on the slider 520. The flexible rubber strips 55 are used to prevent noise from being generated when there is hard contact between the upper track 51 and the upper slider 41, or between the lower track 52 and the lower slider 43 during the sliding process.

[0041] like Figure 1 The unit panel 30 includes a frame composed of a top crossbeam 31, a bottom crossbeam 32, a middle crossbeam 37, a male column 33, and a female column 34. The middle crossbeam 37 connects the male column 33 and the female column 34. A surface material 35 is installed on the frame, which is either a glass panel 35' or a stone panel 35". To ensure reliable load-bearing, the upper sliding member 41 and the lower sliding member 43 are connected to the top crossbeam 31 and the bottom crossbeam 32 respectively through a through-connection method. Specifically:

[0042] The top crossbeam 31 is provided with a slot 310 and the upper slide 41 is provided with a head 410 for locking in the slot 310, so that the upper slide 41 is engaged with the top crossbeam 31. There is a gap between the head 410 of the upper slide 41 and the slot 310 of the top crossbeam 31. An upper pad 42 is provided in the gap, and the upper slide 41, the top crossbeam 31 and the upper pad 42 (such as a rigid PVC pad) are fixed by a fixing screw 420 (such as a self-tapping screw). The bottom crossbeam 32 is provided with a slot 320 and the sliding member 43 is provided with a head 430 for locking in the slot 320, so that the sliding member 43 is engaged with the bottom crossbeam 32. There is a gap between the head 430 of the sliding member 43 and the slot 320 of the bottom crossbeam 32. A lower pad 44 is provided in the gap, and the sliding member 43, the bottom crossbeam 32 and the lower pad 44 (such as a rigid PVC pad) are fixed by a fixing screw 440 (such as a self-tapping screw).

[0043] The unit plate 30 of the present invention adopts the method of bearing its own weight at its lower part. Therefore, in order to prevent the bottom crossbeam 32 from deforming, a rectangular cross-section reinforcing profile 321 is embedded in the inner cavity of the bottom crossbeam 32 at the position corresponding to the lower pad 44 installed on the sliding groove 43. For example, a non-continuous aluminum tube is embedded for reinforcement. The reinforcing profile 321 is fixed in the inner cavity of the bottom crossbeam 32 by locking screws 3210.

[0044] In actual design, a cover 36 is vertically installed between two adjacent unit panels 30, such as... Figure 5 Typically, the cover 36 is fixed to the frame (male column 33 or female column 34) of the unit plate 30 via connecting screws 360.

[0045] Viewed from the left and right, at the same height, the unit panels 30 with the surface material 35 set as glass panels 35' and the unit panels 30 with the surface material 35 set as stone panels 35” are arranged alternately, for reference. Figure 5This can be understood in a way that is not limited. Looking at the left and right directions, at the same height, all unit panels 30 can also be set as unit panels 30 with glass panels 35' as the surface material 35, and similarly, all unit panels 30 can also be set as unit panels 30 with stone panels 35" as the surface material 35.

[0046] In actual installation, for the surface material 35 designed as a unit panel 30 of stone panel 35”, the stone panel 35” is connected to the central crossbeam 37 by L-shaped hanger 38. The specific hanging structure and hanging and adjustment process are well known technologies in this field and will not be described in detail here.

[0047] In this invention, such as Figure 1 The length direction of the upper and lower tracks 51 and 52 is defined as the left and right direction. The direction perpendicular to the left and right direction in the horizontal plane is defined as the inside and outside direction. The inside and outside direction is also called the depth direction, which is the outdoor-indoor direction. The height direction of the unit plate 30 is defined as the up and down direction, which is the vertical direction. Usually, the left and right direction is parallel to the edge of the main structure 90 between floors facing the outside.

[0048] Based on the above-described track-mounted unitized curtain wall system that can be installed indoors, this invention also proposes an installation method, including the following steps:

[0049] 1) Install inter-floor support steel frames 10 on the main structure 90 between each floor, wherein: the bottom of the inter-floor support steel frame 10 is provided with an upper rail 51 along its entire length and the top is provided with a lower rail 52 along its entire length;

[0050] 2) Make a notch (not shown in the figure) on the side of the upper rail 51 at the bottom of the inter-floor support steel frame 10 facing the room, and place the trolley 80 in the lower rail 52 at the top of the inter-floor support steel frame 10.

[0051] 3) Along the left-right direction, install the unit panels 30 one by one between the two adjacent interlayer support steel frames 10. The installation steps for each unit panel 30 include:

[0052] 3-1) Using hoisting equipment, place the unit plate 30 between the upper rail 51 and the lower rail 52 through the notch and place it on the small trolley 80 (e.g. Figure 4 As shown), push the unit plate 30 so that the upper sliding part 41 and the lower sliding part 43 on the unit plate 30 enter the upper track 51 and the lower track 52 respectively;

[0053] 3-2) After pushing the unit plate 30 to the installation position, remove the small trolley 80 so that the sliding part 43 at the bottom of the unit plate 30 is directly placed on the lower track 52.

[0054] 3-3) Connect and fix the unit plate 30 to the adjacent unit plate 30 (i.e., the previously installed unit plate 30);

[0055] 3-4) To ensure the stress requirements under wind load, the upper sliding part 41 of the unit plate 30 is fixed to the upper rail 51 by the limiting bolt 61, and the lower sliding part 43 is fixed to the lower rail 52 by the limiting screw 62 to prevent the unit plate 30 from moving left and right.

[0056] 4) Install interlayer stone panels 70 on the outdoor side of the interlayer support steel frame 10 on the main structure 90 of each floor, wherein the interlayer stone panels 70 and the surface material 35 of the adjacent unit panels 30 should be vertically opposite each other.

[0057] 5) Complete the installation of the track-type unitized curtain wall system of the present invention.

[0058] In practice, after all unit panels 30 at the same height have been installed, any gaps should be sealed promptly to prevent the unit panels 30 from falling off. After the installation of the unit panels 30 and the interlayer stone panels 70 is completed, the installation of components such as the cover 36 can proceed.

[0059] Viewed from the same height along the left and right direction, all unit panels 30 can be set as unit panels 30 with glass panels 35' as the surface material 35, or all unit panels 30 can be set as unit panels 30 with stone panels 35” as the surface material 35. In addition, the unit panels 30 can also be arranged in an alternating pattern of glass panels 35' and stone panels 35”, without any limitations.

[0060] like Figure 4 The small trolley 80 includes an inverted U-shaped steel channel 81, and multiple rollers 82 are movably installed in the steel channel 81 via pins 83. When the small trolley 80 is placed in the lower rail 52, the top surface of the small trolley 80 is higher than the lower rail 52.

[0061] Typically, the steel channel 81 of the small trolley 80 is designed to be 1.2 meters long, and each small trolley 80 is equipped with 5 rollers 82, which is not limited by any constraints. The small trolley 80 can be reused.

[0062] In the actual design, the distance between the upper rail 51 and the lower rail 52 in the vertical direction should be greater than the height of the unit plate 30, so that the unit plate 30 can slide between the upper rail 51 and the lower rail 52 after being placed on the small trolley 80. In addition, after the small trolley 80 is removed, the sliding part 43 at the bottom of the unit plate 30 is directly placed on the lower rail 52. At this time, it should be ensured that the upper sliding part 41 at the top of the unit plate 30 is inside the upper rail 51 to prevent the unit plate 30 from falling out of the interlayer support steel frame 10.

[0063] In actual implementation, after the unit panel 30 is installed in place, the limiting screw 62 is inserted between the sliding groove 431 of the lower sliding member 43 and the side wall of the lower rail 52 to achieve limiting and fixing between the lower sliding member 43 and the lower rail 52. Similarly, the limiting bolt 61 can be pre-installed on the upper rail 51. After the unit panel 30 is installed in place, the limiting bolt 61 is tightened so that it abuts against the upper sliding member 41, thereby limiting and fixing the upper sliding member 41 within the upper rail 51. This completes the limiting and fixing of the unit panel 30 after it is installed in place.

[0064] The advantages of this invention are:

[0065] This invention, through the design of a transverse track, enables the sliding installation of unit panels from the interior side of the main structure. This results in high installation efficiency and low cost, and is not limited by existing structural columns or walls within the main structure. The installed curtain wall structure is safe, stable, and reliable. This invention avoids impacting the external landscape during construction. Barriers can be installed on the exterior side of the main structure according to project requirements, ensuring construction safety. It can be widely applied to new construction projects, renovation projects, and confidential projects.

[0066] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
