Description

Technical Field

[0001] This invention relates to a base profile assembly for a glass curtain wall system and a glass curtain wall system. More specifically, it relates to a base profile assembly for clamping, fixing, or supporting glass panels, which is superimposed and fixedly installed on the main frame of a glass curtain wall system (especially a fireproof glass curtain wall system) or a glass partition system, and a glass curtain wall system using the base profile assembly. Background Technology

[0002] Glass curtain walls on various buildings are typically achieved by installing and fixing glass panels onto a main frame that is pre-installed (or embedded) in the building for mounting the glass panels. For fire-resistant glass curtain walls, the main frame must be made of steel profiles (melting point greater than 1200℃, coated with fire-retardant paint if necessary) to meet requirements for load-bearing capacity, wind pressure resistance, and fire resistance. Therefore, a typical glass curtain wall system (including fire-resistant glass curtain wall systems) includes: a main frame installed (or embedded) in the building for mounting the glass panels; glass panels; fixing components for mounting the glass panels onto the main frame; support components for supporting the glass panels onto the main frame; and sealing components for filling and sealing the gaps between the glass panels and the main frame, fixing components, and support components. The fixing components typically include clamping plate components that hold the glass panels, and fastening components that secure the clamping plate components to the main frame while the glass panels are clamped. The supporting components typically include a support plate component that supports the glass panel and a support plate fixing component that secures the support plate component to the main frame. Furthermore, the main frame typically consists of vertical beams (parallel to the building's height) and horizontal beams (perpendicular to the vertical beams). Therefore, the fixing components, together with the vertical and horizontal beams, typically clamp and secure the glass panel, while the supporting components, together with the horizontal beams, typically support the glass panel.

[0003] In existing fire-resistant glass curtain wall systems, the main frame's vertical and horizontal beams are made of steel profiles (including various rectangular steel pipes, H-beams, T-beams, I-beams, etc.), and the structure for clamping and fixing the glass panels is achieved using screws or bolts connected and fixed to the main frame (vertical and horizontal beams). Specifically, for example... Figure 1(As shown in the diagram using a grooved boss self-tapping screw) The structure for clamping and fixing the glass plate G includes a boss 72 formed on the main frame (vertical beam and horizontal beam) 70 for screwing into an inner hole 71 for screwing into a screw 80 as a fastening component. When fixing the glass plate G, the glass plate G is placed against the contact surface 73 of the main frame (vertical beam and horizontal beam) 70. Then, with the outer cover 90, which is a clamping plate component, clamped together with the main frame 70, the screw 80, which passes through the through hole (not shown) on the outer cover 90, is screwed into the inner hole 71. The diameter of the inner hole 71 is slightly smaller than the outer diameter of the screw 80, that is, the screw 80 is a self-tapping screw. During the process of screwing the screw 80 into the inner hole 71, the screw 80 engages (screws) with the inner wall of the inner hole 71, so that the glass plate G is clamped and fixed on the main frame 70 through the main frame 70, the screw 80 and the outer cover 90. Using this structure to clamp and fix the glass plate, since the main frame 70 needs to use integral irregular steel profiles (usually closed irregular straight seam welded pipes), the following problems exist. (1) Integral irregular steel profiles require irregular forming molds (one set of dozens of forming molds is required for one cross-sectional shape, specification, and wall thickness). The investment in forming equipment (roll forming plus high frequency welding) and special molds is very high. The debugging time for changing molds (changing production) is long, the rate of defective products is high, and the product cost is relatively high. (2) Due to its shape, size and material properties, the material thickness of integral irregular steel profiles can usually only be limited to a very small range (e.g., 2.3~2.5mm; 2.7~3.0mm). Its bending modulus can only be obtained by passing through the form factor test. To increase the bending direction dimension, the number of special forming molds must be increased, which leads to increased costs; (3) For some special occasions, special materials (such as Q355E, Q460E, SS304, SS316, etc.) are required. It is difficult for integral irregular steel profiles to be formed or meet the design requirements; (4) The glass plate is clamped and fixed by self-tapping screw structure. Since the engagement (threading) strength between screw 80 and the inner wall of inner hole 71 is limited, it is often impossible to meet the relevant requirements when the fire resistance requirements are high, that is, when the thickness of glass plate G is large (the number of pieces is large).

[0004] To address the aforementioned issues, existing glass curtain wall systems have adopted methods such as... Figure 2 The example shown is called a superimposed clamping and fixing structure. Specifically, as... Figure 2As shown, compared to directly forming the base profile on the vertical and horizontal beams, the base profile 100 is formed separately. The boss 102 of the inner hole 101 used for clamping and fixing the glass plate is not directly formed on the main frame (vertical and horizontal beams) 104, but is formed on the base profile 100. Although this configuration solves the problem of complex process and high cost caused by the need to use special-shaped steel structures to form the main frame (vertical and horizontal beams) in the prior art, it still uses self-tapping screws 105 to clamp and fix the glass plate G. Therefore, for situations with high fire resistance requirements, i.e., large thickness of glass plate G (many pieces), the base profile or base profile assembly with this configuration cannot meet the relevant requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a base profile assembly and a glass curtain wall system for a glass curtain wall system that can reliably and securely clamp and fix glass panels.

[0006] This invention provides a base profile assembly for a glass curtain wall system, which is fixed to the main frame of the curtain wall and used to clamp, fix, and / or support glass panels. The base profile assembly comprises: a base profile, tensioning screws, locking pads or locking support pads, and locking connecting sleeves. The base profile is a long strip profile integrally formed from a metal sheet, including: an engaging guide groove, and extension portions extending outwards to both sides along the width direction of the engaging guide groove. The engaging guide groove has a trapezoidal cross-section with a wide bottom and a narrow opening, and two inclined sides. The extension portions include a first extension portion and a second extension portion. The outer surface of the outer surface and the bottom of the engaging guide rail groove are surfaces that contact the main frame of the curtain wall. The bottom of the first extension and / or the engaging guide rail groove is provided with a base through hole. The tensioning screw includes: a screw portion and a head at one end of the screw portion; the screw portion has external threads along its length; the head has a longitudinal cross-sectional shape that is trapezoidal with two first inclined sides, the rear end of which is smaller than the front end of the head connected to the screw portion and larger than the front end of the head; the locking pad is a profile with a trapezoidal longitudinal cross-section having a bottom edge and two second inclined sides, the engaging edges constituting the two second inclined sides extending along both ends of the top plate constituting the bottom edge. The top plate has a through hole with a diameter larger than that of the screw portion. The width of the top plate at the connection with the two engaging sides is greater than or equal to the width of the opening. The included angle between the two engaging sides is equal to the included angle between the two inclined sides of the engaging guide rail groove. The locking support pad includes a locking pad portion and a support portion for supporting the glass plate. The locking pad portion is a profile with a trapezoidal longitudinal section having one bottom edge and two second inclined sides. The engaging sides constituting the two second inclined sides extend along both ends of the top plate portion constituting the bottom edge. The top plate has a through hole with a diameter larger than that of the screw portion. The width of the top plate at the connection with the two engaging sides is greater than or equal to the width of the opening. The included angle between the two engaging sides is equal to the included angle between the two inclined sides of the engaging guide rail groove. The width of the connecting edge is greater than or equal to the width of the opening, and the included angle between the two engaging edges is equal to the included angle between the two inclined edges of the engaging guide groove. The support part is located on the top plate near one of the two engaging edges and is erected perpendicularly to the top plate in a direction opposite to the direction of extension of the engaging edge. The locking connecting screw sleeve has an internal threaded hole through it. A portion of the axial direction of the internal threaded hole is used to engage with the external thread of the screw part, and another portion of the axial direction of the internal threaded hole is used to engage with the screw used to clamp the glass plate. The outer diameter of the locking connecting screw sleeve is greater than the diameter of the through hole of the pad.The longitudinal section width of the rear end of the head is smaller than the longitudinal section width of the inner surface of the opening of the engaging guide groove, while the longitudinal section width of the front end of the head is smaller than the longitudinal section width of the inner surface of the bottom of the engaging guide groove but larger than the longitudinal section width of the inner surface of the opening of the engaging guide groove. After the head is engaged with the opening of the engaging guide groove, the threaded part passes through the through hole of the pad and the inner surfaces of the two engaging edges engage with the outer surface of the opening of the engaging guide groove. Finally, the inner threaded hole is screwed into the outer thread of the threaded part and tightened, thus assembling the base profile assembly.

[0007] Based on the above invention, the base profile is preferably formed by integrally bending a steel plate; the first extension portion is formed by bending relative to the engaging guide groove; and the second extension portion is formed by bending relative to the first extension portion.

[0008] Based on the above invention, it is preferable that the surface of the first extension that contacts the main frame of the curtain wall and the surface of the engaging guide groove that contacts the main frame of the curtain wall have an acute angle.

[0009] Based on the above invention, it is preferable that the head is formed as a square head with a square cross-sectional shape.

[0010] The present invention also provides a glass curtain wall system, comprising a base profile assembly as described above, fixed to the main frame of the curtain wall for clamping, fixing or supporting glass panels, an outer cover plate for clamping the glass panels, and fastening screws for fastening the outer cover plate to the base profile assembly by screwing into the inner thread hole of the locking connecting screw sleeve when the glass panels are clamped.

[0011] In the base profile assembly and glass curtain wall system of the present invention, the glass panel can be stably installed and fixed on the main frame of the curtain wall by the base profile assembly. At the same time, compared with the prior art, it does not use special profiles to form the main frame of the curtain wall or the base profile, nor does it form bosses with screw holes on the main frame of the curtain wall or the base profile for self-tapping screw engagement and fixing. That is, it does not use a self-tapping screw structure. Therefore, the glass curtain wall system using the base profile assembly of the present invention can not only reduce costs, but also reliably and stably clamp and fix the glass panel. The effect is even more significant for fireproof glass curtain wall systems. Attached Figure Description

[0033] The base profile assembly and glass curtain wall system of the present invention will be described below with reference to the drawings.

[0034] The base profile assembly 1 for the glass curtain wall system of the present invention, such as Figure 3 As shown, it has: a base profile 10, a tensioning screw 20, a locking washer 30, and a locking connecting screw sleeve 40.

[0035] The base profile 10, such as Figure 4 As shown, the base profile 10 is a long strip-shaped profile formed by integrally bending a steel plate. The usable length of this base profile 10 corresponds to the width or height of the glass curtain wall window to be installed; that is, in actual use, it is cut to the required length according to the width or height of the glass curtain wall window. In this embodiment, the base profile 10 includes: a locking guide groove 11, and extension portions 12 that extend symmetrically outwards to both sides along the width direction of the locking guide groove 11. However, it is not limited to this; the extension portions 12 on both sides may not extend symmetrically outwards along the width direction of the locking guide groove 11, that is, one side's extension portion 12 may be wider than the other side's extension portion 12.

[0036] Figure 5 It is the base profile 10 edge Figure 4 A sectional view taken along line AA. The engaging guide groove 11, as shown... Figure 4 and Figure 5As shown, its longitudinal cross-section is a trapezoid with a wide bottom 11a and a narrow opening 11b, including two inclined sides 11c that serve as first inclined sides. This trapezoidal engaging guide groove 11 is sometimes referred to as a dovetail groove in this technical field. The outer surface 11d of the bottom 11a of the engaging guide groove 11 is the surface that contacts the main frame K of the curtain wall, and first base through holes 11e, which serve as base through holes, are provided at certain intervals on the base profile 10. In addition, the two inclined sides 11c of the engaging guide groove 11 respectively have an inner surface 11f that can slide with the tensioning screw 20 described later and an outer surface 11g that can slide with the locking pad 30 described later. In this embodiment, the groove width of the bottom 11a of the engaging guide groove is W1, the inner groove width of the opening 11b of the engaging guide groove is W2, the outer width is W3, the included angle of the inner surface 11f of the two inclined sides 11c is θ1, the included angle of the outer surface 11g of the two inclined sides 11c is θ2, and the groove depth is H1.

[0037] The extension portion 12, such as Figure 4 and Figure 5 As shown, the base profile 10 is formed by symmetrically bending to both sides relative to the engaging guide groove 11 in the width direction. It includes first extensions 12a, 12a and second extensions 12b, 12b. Specifically, the first extensions 12a, 12a are formed by symmetrically bending to both sides relative to the engaging guide groove 11 in the width direction of the base profile 10, while the second extensions 12b, 12b are formed by symmetrically bending to both sides relative to the first extensions 12a, 12a in the width direction of the base profile 10. The first extensions 12a, 12a have outer surfaces 12c, 12c that contact the main frame K of the curtain wall, and second base through holes 12d, 12d are provided at certain intervals along the length direction of the base profile 10, serving as base through holes.

[0038] Furthermore, the outer surface 11d of the bottom 11a of the engaging guide groove is on the same plane as the outer surfaces 12c, 12c of the first extension portions 12a, 12a. The second extension portions 12b, 12b, formed by bending relative to the first extension portions 12a, 12a, are positioned higher than the first extension portions 12a, 12a in the height direction of the base profile 10. In this embodiment, the first base through hole 11e and the second base through holes 12d, 12d are circular holes, and the diameter of the first base through hole 11e is larger than the diameter of the second base through holes 12d, 12d. However, this is not a limitation; for example, the diameter of the first base through hole 11e can be less than or equal to the diameter of the second base through holes 12d, 12d. Additionally, at least one of the first base through holes 11e and the second base through holes 12d, 12d can be a slot or an elliptical hole.

[0039] The tensioning screw 20, such as Figure 6 As shown in (a) and (b), it includes: a screw portion 21 and a head 22 provided at one end of the screw portion 21; the screw portion 21 is provided with an external thread 23 along its length direction; the head 22 has a longitudinal cross-sectional shape of a trapezoid with two inclined sides 22c serving as second inclined sides, where the rear end 22a connected to the screw portion 21 is smaller and the front end 22b, which is farther away from the screw portion 21, is larger. In this embodiment, the diameter D1 of the screw portion 21 is assumed to be smaller than the groove width W2 of the opening 11b of the engaging guide groove, that is, the screw portion 21 can pass through the opening 11b. In addition, the head 22 has a square cross-sectional shape, and if the side length of its rear end 22a is W4 and the side length of its front end 22b is W5, then W5 > W4. Furthermore, the included angle between the two inclined sides 22c of the head 22 is set to θ3, the height (i.e., trapezoidal height) of the head 22 is set to H1, and the length of the screw part 21 is set to L1. In this embodiment, the included angle θ3 is set to be equal to the included angle θ1, the side length W4 is set to be greater than the inner groove width W2, and the side length W5 is set to be less than the groove width W1. That is to say, when two of the inclined sides 22c of the head 22 are in contact with the inner surface 11f of the two inclined sides 11c of the engaging guide groove 11, the head 22 can slide between the bottom 11a and the opening 11b of the engaging guide groove 11. At the same time, since the side length W4 is greater than the inner groove width W2, the head 22 cannot protrude from the opening 11b to the outside of the engaging guide groove 11, and the head 22 and the inner surface 11f form a wedge fit.

[0040] The locking pad 30 is a profile integrally formed from steel plate by bending or stamping, having a bottom edge and two inclined sides as third inclined sides, with a trapezoidal longitudinal section. The bottom edge is as follows: Figure 7As shown in (a) and (b), the two third oblique edges of the top plate portion 31 are the engaging edges 32 extending from both ends of the top plate portion 31. Additionally, a pad through-hole 31a is provided on the top plate portion 31, and the diameter D2 of this pad through-hole 31a is set to be slightly larger than the diameter D1 of the screw portion 21. In this embodiment, when the width at the intersection of the inner surface 32a of the engaging edge 32 and the bottom surface 31b of the top plate portion 31 is set to W6, and the included angle between the inner surfaces 32a of the two engaging edges 32 is set to θ4, W6 is set to be equal to or slightly larger than W3, and θ4 is set to be equal to θ2. In other words, when the inner surface 32a of the engaging edge 32 of the locking pad 30, which serves as the two inclined sides, contacts and engages with the outer surface 11g of the two inclined sides 11c of the engaging guide groove 11, the locking pad 30 is fastened to the outside of the two inclined sides 11c of the engaging guide groove 11 along the outer surface 11g of the two inclined sides 11c of the engaging guide groove 11. Furthermore, the length of the locking pad 30 in the longitudinal direction of the base profile 10 is set to L2.

[0041] The locking connecting screw sleeve 40, such as Figure 8 As shown, it has an internal threaded hole 41 that passes through the locking connecting screw sleeve 40. A portion of the internal threaded hole 41 is used to engage with the external thread 23 of the screw portion 21, while the other portion is used to engage with the screw M3 described later. That is, the inner diameter of the internal threaded hole 41 is the same as the outer diameter of the external thread 23 and the screw M3, meaning they have dimensions that allow them to engage with each other. Furthermore, the outer diameter D3 of the locking connecting screw sleeve 40 is set to be larger than the diameter D2 of the through hole 31a of the pad. The axial length of the locking connecting screw sleeve 40 can be set to various lengths depending on the total thickness of the glass plate G to be clamped and installed.

[0042] The base profile assembly 2 for the glass curtain wall system of the present invention includes: a base profile 10, a tensioning screw 20, a locking support pad 50, and a locking connecting sleeve 40.

[0043] The base profile assembly 2 is identical to the base profile assembly 1 in all components except for the locking support pad 50, which differs from the locking pad 30 in the base profile assembly 1. These components include the base profile 10, the tensioning screw 20, and the locking connecting sleeve 40. Therefore, for ease of explanation, only the structure of the locking support pad 50 will be described, omitting the description of other components.

[0044] The locking support pad 50, such as Figure 9 and Figure 10As shown, it has a locking pad portion 51 and a support plate 52 for supporting the glass plate. The locking pad portion 51 has the same shape and structure as the locking pad 30, and is formed by bending, stamping, or forging a steel plate. It has a bottom edge and two inclined sides forming a trapezoidal profile in longitudinal section. The bottom edge is as shown... Figure 9 and Figure 10 The top plate portion 53 shown has two third oblique edges, which are engaging edges 54 extending from both ends of the top plate portion 53. Additionally, a pad through-hole 53a is provided on the top plate portion 53, and the diameter D4 of this pad through-hole 53a is set to be slightly larger than the diameter D1 of the screw portion 21. In this embodiment, when the width at the intersection of the inner surface 54a of the engaging edge 54 and the bottom surface 53b of the top plate portion 53 is set to W7, and the included angle between the inner surfaces 54a of the two engaging edges 54 is set to θ5, W7 is set to be equal to or slightly larger than W3, and θ5 is set to be equal to θ2. In other words, when the inner surface 54a of the engaging edge 54 of the locking support pad 50, which serves as the two inclined sides, contacts and engages with the outer surface 11g of the two inclined sides 11c of the engaging guide groove 11, the locking support pad 50 is fastened to the outside of the two inclined sides 11c of the engaging guide groove 11 along the outer surface 11g of the two inclined sides 11c of the engaging guide groove 11. The locking support pad 50 differs from the locking pad 30 in that it also has a support plate 52 for supporting the glass plate. This support plate 52 is disposed on the top plate portion 53 near one of the two engaging edges 54, and is erected perpendicular to the top plate portion 53 in a direction opposite to the extension direction of the engaging edge 54. Furthermore, the length of the locking support pad 50 in the longitudinal direction of the base profile 10 is set to L3 in this embodiment. If L3 is twice the length of L2, then the pad through holes 53a on the top plate portion 53 are two holes spaced apart. However, this is not a limitation; in other embodiments, L3 may be equal to L2, or L3 may be more than twice the length of L2. Correspondingly, the pad through holes 53a on the top plate portion 53 may be one or multiple holes spaced apart. Furthermore, the support plate 52 may be integrally formed with the locking pad portion 51, or it may be erected on the top plate portion 53 by welding or other methods. Moreover, the angle between the support plate 52 and the top plate portion 53 may be an angle other than 90 degrees (e.g., an angle between 75 and 115 degrees). Since the locking support pad 50 has a locking pad portion 51 and a support plate 52 for supporting the glass plate, the locking support pad 50, in addition to having the same locking function as the locking pad 30, also has a supporting function for supporting the glass plate.

[0045] The following is for reference Figure 11 and Figure 12 The installation method of mounting the base profile assemblies 1 and 2 of the glass curtain wall system of the present invention onto the main frame K of the curtain wall will be described.

[0046] First, for the base profile 10, after attaching the outer surface 11d of the bottom 11a of the engaging guide groove and the outer surfaces 12c, 12c of the first extension portions 12a, 12a, 12c, which are set on the same plane, to the mounting surface K1 of the main curtain wall frame K, screws M1 are screwed onto the main curtain wall frame K through the second base through holes 12d, 12d. Then, the tensioning screw 20 is tightened so that its head 22 is aligned with... Figure 4 The arrow P indicates that the base profile 10 is inserted into the engaging guide rail groove 11 from either end, with the screw portion 21 positioned outside the opening 11b. After moving the tensioning screw 20 to the designated installation position within the engaging guide rail groove 11, the screw M2 is passed through the first base through hole 11e and screwed onto the main curtain wall frame K (see...). Figure 3 Next, with the locking pad 30 or the locking support pad 50 having its through hole 31a or through hole 53a passed through by the screw portion 21, the inner surfaces 32a of the two engaging edges 32 or the inner surfaces 54a of the two engaging edges 54 are brought into contact with the outer surfaces 11g of the two inclined edges 11c of the engaging guide groove 11, thereby fastening it onto the base profile 10. Then, the inner threaded hole 41 of the locking connecting screw sleeve 40 is screwed into the outer thread 23 of the screw portion 21. At this time, as the inner threaded hole 41 of the locking connecting screw sleeve 40 is screwed into the outer thread 23 of the screw portion 21, the head 22, i.e., the tensioning screw 20, is locked in the engaging guide groove 11. Simultaneously, the locking pad 30 or the locking support pad 50 is locked between the engaging guide groove 11, i.e., the base profile 10, and the locking connecting screw sleeve 40. Since the head 22 and the inner surface 11f form a wedge fit, the tighter the locking connecting screw sleeve 40 is screwed relative to the tensioning screw 20, the tighter the wedge fit between the head 22 and the inner surface 11f becomes, meaning the tensioning screw 20 is more securely fixed to the base profile 10.

[0047] The present invention also provides a glass curtain wall system, which includes the base profile assembly 1 and / or the base profile assembly 2 fixed on the main frame K of the curtain wall for clamping, fixing or supporting glass panels G, an outer cover plate 60 for clamping glass panels G, and fastening screws M3 for fastening the outer cover plate 60 to the base profile assembly 1 by screwing into the inner thread hole 41 of the locking connecting screw sleeve 40 when the glass panels G are clamped.

[0048] The following is for reference Figure 11 and Figure 12 This section describes a glass curtain wall system in which the glass panel G is installed using the base profile assembly 1 and / or the base profile assembly 2 of the present invention. Furthermore, in this embodiment, the installation of a glass curtain wall system for only one curtain wall unit will be described.

[0049] like Figure 11 As shown, the curtain wall unit includes curtain wall mullions K2 and curtain wall beams K3 and K4. Curtain wall beam K3 is the middle and bottom beam, while curtain wall beam K4 is the top beam. When the glass panel G is installed onto the main frame K of the curtain wall, it is only necessary to clamp the glass panel G on the curtain wall mullions K2 and curtain wall beams K4. However, on the curtain wall beams K3, not only is it necessary to clamp the glass panel G, but it also needs to be supported. Therefore, on the curtain wall mullions K2 and curtain wall beams K4, only the base profile assembly 1 with locking pads 30 is needed to clamp and fix the glass panel G. However, on the curtain wall beams K3, not only is it necessary to clamp and fix the glass panel G using the base profile assembly 1 with locking pads 30, but it also needs to be supported by the base profile assembly 2 with locking support pads 50. Thus, as... Figure 12 As shown, multiple base profile assemblies 1 with locking pads 30 and base profile assemblies 2 with locking support pads 50 are alternately arranged on the curtain wall beam K3. The spacing and number of base profile assemblies 1 and base profile assemblies 2 can be freely selected and combined according to the thickness and weight of different glass panels G and the size of the curtain wall unit, and no special restrictions are imposed here.

[0050] The following is for reference Figure 13 and Figure 14 The installation of base profile assembly 1 and base profile assembly 2 on the aforementioned curtain wall beam K3 will be described. The method of installing base profile assembly 1 on the aforementioned curtain wall mullions K2 and curtain wall beam K4 is basically the same as the method of installing base profile assembly 1 on the curtain wall beam K3, and its detailed description is omitted here.

[0051] Figure 13 It is along Figure 12 A sectional view along the BB line. First, as... Figure 13 and Figure 14 As shown, following the installation method described above for installing the base profile assembly 1 onto the main curtain wall frame K, the base profile assembly 1 is installed onto the curtain wall beam K3. Then, a sealing strip F1 (which can also be a fireproof sealing strip) is installed by engaging with the second extension portions 12b, 12b of the base profile 10 of the base profile assembly 1. Next, the glass panel G to be installed (which can be composed of multiple overlapping glass panels) is placed so that its mounting hole G1 is passed through the locking connecting screw sleeve 40. Then, as... Figure 13As shown, with the outer cover plate 60 clamping the sealing strip F2 (which can also be a fireproof sealing strip), screws M3 into the inner threaded hole 41 of the locking connecting sleeve 40 and tighten them, thereby clamping and fixing the glass plate G onto the curtain wall beam K3. Finally, a decorative cover B is placed on the outside of the outer cover plate 60. The outer cover plate 60, decorative cover B, sealing strip F1, sealing strip F2, etc., can all be made of the same materials as those in the prior art, and no special restrictions are imposed here.

[0052] Figure 15 It is along Figure 12 A sectional view taken along the CC line. (Example) Figure 15 and Figure 16 As shown, firstly, following the installation method described above for installing the base profile assembly 1 onto the main curtain wall frame K, the base profile assembly 2 is installed onto the curtain wall beam K3. At this time, with the support plate 52 of the locking support pad 50 positioned above the supporting glass panel G, a sealing strip F1 (which can also be a fireproof sealing strip) is set by engaging with the second extension 12b, 12b of the base profile 10 of the base profile assembly 2. Next, the glass panel G to be installed (which can be composed of multiple overlapping glass panels) is positioned so that its mounting hole G1 is passed through the locking connecting screw sleeve 40, and with the sealing strip F3 (which can also be a fireproof sealing strip) clamped between at least the mounting hole G1 and the support plate 52, the support plate 52 supports the glass panel G. Then, as... Figure 15 As shown, with the outer cover plate 60 clamping the sealing strip F2 (which can also be a fireproof sealing strip), screws M3 into the inner threaded hole 41 of the locking connecting sleeve 40 and tighten them. This clamps and fixes the glass plate G onto the curtain wall beam K3, while simultaneously supporting it on the curtain wall beam K3 via the base profile assembly 2. Finally, a decorative cover B is placed over the outer cover plate 60. The outer cover plate 60, decorative cover B, sealing strips F1, F2, and F3 can all be made of materials similar to those in existing technologies, and no particular limitations are imposed here.

[0053] Therefore, by using the superimposed base profile assembly of the present invention, the glass panel can be stably installed and fixed on the main frame K of the curtain wall. At the same time, compared with the prior art, neither the curtain wall main frame or base profile is formed by special profiles, nor are bosses with screw holes for self-tapping screws formed on the curtain wall main frame or base profile. That is, no self-tapping screw structure is used. Therefore, the glass curtain wall system using the base profile assembly of the present invention can not only reduce costs, but also reliably and stably clamp and fix the glass panel. The effect is even more significant for fireproof glass curtain wall systems.

[0054] In the above embodiments, the head 22 has a square cross-sectional shape, or it can be a rectangle, as long as it has two parallel sides with the same side length as the square side. Furthermore, the shape of the sides that do not mate with the inner surfaces 11f of the two inclined portions 11c of the engaging guide groove 11 is not limited; for example, they can be curved or arc-shaped.

[0055] Furthermore, not every location on the base profile assembly supporting the glass plate G requires clamping and securing the glass plate G. For example, such as... Figure 17 As shown, instead of the tensioning screw 20 and the locking connecting sleeve 40, the base profile 10 and the locking support pad 50 are fixedly installed onto the curtain wall beam K3 using a bolt structure M4 or screws (not shown).

[0056] In addition, the base profile 10 can also be formed by forging or casting, or it can be made of materials other than steel plates with the required strength.

[0057] Furthermore, the selection of the material and thickness of the base profile 10, tensioning screw 20, locking pad 30 or locking support pad 50, and locking connecting screw sleeve 40 is based on the total thickness of the glass panels in the glass curtain wall to be installed, which is a conventional selection in this technical field and is not particularly limited here.

[0058] In addition, in this embodiment, the outer surface 11d of the bottom 11a of the engaging guide groove and the outer surfaces 12c, 12c of the first extension portions 12a, 12a are disposed on the same plane. As another embodiment of this invention, the outer surface 11d of the bottom 11a of the engaging guide groove and the outer surfaces 12c, 12c of the first extension portions 12a, 12a can also be disposed on different planes, that is, the outer surface 11d of the bottom 11a of the engaging guide groove and the outer surfaces 12c, 12c of the first extension portions 12a, 12a have an acute angle between them. Figure 18 As shown, the outer surface 11d of the bottom 11a of the engaging guide groove has an angle α1 with the outer surfaces 12d of the bottom 12c of the first extension 12a, 12c. A base profile assembly 1 or base profile assembly 2 with such a base profile 10 can be applied to, for example... Figure 19 The glass curtain wall system shown has a concave curved corner. Similarly, as... Figure 20 As shown, the outer surface 11d of the bottom 11a of the engaging guide groove has an angle α2 with the outer surfaces 12d of the bottom 12c of the first extension 12a, 12c. A base profile assembly 1 or base profile assembly 2 with such a base profile 10 can be applied to, for example... Figure 21 The glass curtain wall system shown has a convex arc-shaped beveled corner. Angles α1 and α2 are set as acute angles greater than 0 degrees and less than 90 degrees, preferably 3 degrees to 45 degrees, and more preferably 5 degrees to 30 degrees.
