[0054] Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0055] In some embodiments, such as Figure 1 , Figure 3 , Figure 6 , Figure 8 and Figure 10 ​As shown, in view of the limitations of the existing semi-concealed frame curtain wall structure, a fully concealed point support frame curtain wall system is provided, which mainly comprises a stand column 100, a glass unit 200, a plurality of sets of inner concealed frame fasteners 300 and a plurality of sets of outer pressing plate fasteners 400.

[0056] A plurality of sets of inner concealed frame fasteners 300 are respectively installed at the connection between adjacent two glass units 200, and are respectively used for mounting and fixing different positions of the glass unit 200. Specifically, the inner sides of the adjacent two glass units 200 are respectively connected with the stand column 100 through the first fastener 303 and the second fastener 304 at both ends of each inner concealed frame fastener 300, and the connection between the first fastener 303 and the second fastener 304 is mutually fastened and arranged in concentric circles to be rotatable to adapt to the installation requirements of different glass angles.

[0057] A plurality of sets of outer pressing plate fasteners 400 are respectively installed at the connection between adjacent two glass units 200, and are respectively used for mounting and fixing different positions of the glass unit 200. Specifically, the outer sides of the adjacent two glass units 200 are respectively connected with the stand column 100 through the first pressing plate 401 and the second pressing plate 402 at both ends of each outer pressing plate fastener 400 via an adapter 405, and the first pressing plate 401 and the second pressing plate 402 are respectively engaged with the sawtooth column 403 at the end of the adapter 405 to adapt to the fixing requirements of different glass angles.

[0058] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 10 As shown, the outer side end of the stand column 100 is designed as a reverse U-shaped notch 101, and a plurality of sets of inner concealed frame fasteners 300 and a plurality of sets of outer pressing plate fasteners 400 are installed in the reverse U-shaped notch 101 along the length direction thereof. The stand column 100 is a curtain wall keel and is made of aluminum alloy.

[0059] The two ends of the reverse U-shaped notch 101 are connected with adjacent two glass units 200 through a sealing strip 102. The sealing strip 102 is an O-shaped sealing strip with a special shape, which is installed between the stand column 100 and the glass unit 200 and plays a buffering protection role for the glass unit 200.

[0060] In addition, in order to realize the installation and fixation of the inner hidden frame fastener 300 and the outer pressing plate fastener 400, a first clamping groove 103 is arranged at the middle position of the inner end face of the inverted U-shaped notch 101 along the length direction, for inserting and installing the first locking bolt 301 and the second locking bolt 407 from the top notch. The first locking bolt 301 is an M6 stainless steel pan head machine screw.

[0061] Meanwhile, a second clamping groove 104 is arranged at the both sides of the first clamping groove 103, for inserting and installing the clamping plate 406 from the top notch; and a first limiting protrusion 105 is arranged at the both ends of the notch of the first clamping groove 103, for limiting and installing the sub-frame pressing block 302.

[0062] In some embodiments, as shown in Figure 1 , Figure 3 , Figure 6 , Figure 8 and Figure 10 , two adjacent glass units 200 share one curtain wall stile column 100. In order to ensure the sealing between the two glass units 200 after installation, the O-shaped sealing strip 201 and the sealant 202 are used to seal and connect between the two adjacent glass units 200, and the O-shaped sealing strip 201 is located at the inner side of the sealant 202, which is formed by coating and curing the sealant liquid.

[0063] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the inner hidden frame fastener 300 mainly includes the first locking bolt 301, the sub-frame pressing block 302, the first fastener 303 and the second fastener 304, and the first locking bolt 301, the sub-frame pressing block 302, the first fastener 303 and the second fastener 304 are all made of aluminum alloy material.

[0064] Specifically, the inner end of the first locking bolt 301 is inserted from the top opening of the inverted U-shaped notch 101 and buckled and installed in the first clamping groove 103 at the outer side of the stile column 100, and the outer end is locked and connected to the middle part of the sub-frame pressing block 302 by a nut, so as to fix and install the sub-frame pressing block 302 at the corresponding height in the inverted U-shaped notch 101.

[0065] The first fastener 303 is a inverted L-shaped structure, which is two, symmetrically arranged left and right, and the outer side wall of the inner end is respectively pressed and connected to the both ends of the sub-frame pressing block 302. The both ends of the sub-frame pressing block 302 are pressed on the first fastener 303 by the first locking bolt 301, so as to realize the positioning and installation of the first fastener 303.

[0066] Corresponding to the first fastener 303, the second fastener 304 is F-shaped structure, which is also two, symmetrical arrangement. The second fastener 304 one end with the corresponding first fastener 303 outer end rotatable connection, the other end with the inner side of the glass unit 200 connection.

[0067] When the need to tilt installation of two adjacent glass units 200 at a certain angle, the second fastener 304 can be relative to the first fastener 303 in the connection between the two rotation, thus ensuring the second fastener 304 and the inner side of the glass unit 200 stable connection on the basis of, to adapt to different glass angle requirements.

[0068] It is worth noting that, between the outer end face of the second fastener 304 and the glass unit 200 are also respectively arranged side by side support block 305 and buffer pad 306. Support block 305 using stainless steel, aluminum alloy or hard plastic material, and located in the outer side of the square block 3042 end, mainly for supporting the connection of glass unit 200. Buffer pad 306 using rubber material, and set in the outer side of the bottom plate 3041 end, and fit glass unit 200 installation, for the second fastener 304 in relative rotation, can produce elastic deformation, in order to reduce the extrusion stress on the glass unit 200, thereby improving the safety of the system structure.

[0069] As one of the preferred embodiments, as shown in Figure 1 , Figure 2 and Figure 5 , the vice frame pressing block 302 is a cover plate structure with inner flat and outer arc, that is, the inner end face is flat and the outer end is circular arc. And a through hole is formed in the center axis of the vice frame pressing block 302 for installing the first locking bolt 301.

[0070] In order to ensure the stability of the installation of the vice frame pressing block 302 and avoid left and right shaking and slipping, two first limiting bosses 3021 are arranged on the inner end face of the vice frame pressing block 302, which are symmetrical and correspond to the first limiting protrusions 105. The vice frame pressing block 302 is installed and positioned between the two first limiting protrusions 105 through the two first limiting bosses 3021.

[0071] In addition, in order to ensure the adjustable connection between the first fastener 303, the second limiting boss 3022 is arranged at the two end positions of the inner end face of the vice frame pressing block 302, which cooperates with the inner end of the first fastener 303. The point connection between the vice frame pressing block 302 and the first fastener 303 is realized through the second limiting boss 3022. The point connection mode facilitates the left and right movement of the first fastener 303 and realizes the rapid adjustment of the position of the first fastener 303.

[0072] As one of the preferred embodiments, as shown in Figure 2 and Figure 5 , the first fastener 303 is in an inverted L-shaped structure, and two ends of the inner end face are respectively provided with pressing bosses 3031, and one end is connected with a circular fastener 3033 through a Z-shaped connecting piece 3032. The pressing bosses 3031, the Z-shaped connecting piece 3032 and the circular fastener 3033 are integrally processed and formed.

[0073] Correspondingly, the second fastener 304 is in an F-shaped structure, which is integrally processed and formed by a bottom plate 3041 and a square clamping block 3042. The bottom plate 3041 is in a plate-shaped structure with one end thin and the other end thick, and the inner side of the thicker end is provided with the square clamping block 3042; the square clamping block 3042 is provided with a circular clamping groove 3043, and the circular clamping groove 3043 is rotatably connected with the circular fastener 3033 on the first fastener 303.

[0074] As can be seen from Figure 1 , Figure 3 and Figure 6 , the outer end of the second fastener 304 is tightly fitted on the glass unit 200 on one side. When the glass unit 200 on one side is installed at a certain angle relative to the glass unit 200 on the other side, the glass unit 200 drives the second fastener 304 on the inner side to rotate synchronously in the process of rotation. Since the circular clamping groove 3043 of the second fastener 304 is concentrically connected with the circular fastener 3033 of the first fastener 303, when the second fastener 304 rotates, the circular clamping groove 3043 at one end of the second fastener 304 rotates relative to the circular fastener 3033, thereby realizing self-adaptive rotation adjustment of the second fastener 304.

[0075] In some embodiments, as shown in Figure 11 , Figure 12 , Figure 13 and Figure 14 , the inner hidden frame fastener 300 mainly includes a first locking bolt 301, a sub-frame pressing block 302, a first fastener 303, a second fastener 304 and a limiting clamping column 307, and the first locking bolt 301, the sub-frame pressing block 302, the first fastener 303, the second fastener 304 and the limiting clamping column 307 are all processed from aluminum alloy materials. Different from the above-mentioned embodiments, the first fastener 303 and the second fastener 304 directly adopt a concentric clamping mode with a specific structure design. One end of the first fastener 303 is clamped and connected with one end of the second fastener 304 through the limiting clamping column 307.

[0076] Specifically, a first rotating sleeve 3034 is arranged at the middle of one end of the first fastener 303, and two first rotating clamping grooves 3035 are respectively arranged on the inner cavity wall of the first rotating sleeve 3034 along the length direction of the first rotating sleeve 3034. Correspondingly, a second rotating sleeve 3044 is arranged at the top end and the bottom end of one end of the second fastener 304, and two second rotating clamping grooves 3045 are respectively arranged on the inner cavity wall of the second rotating sleeve 3044 along the length direction of the second rotating sleeve 3044.

[0077] The limiting clamping column 307 is a cylindrical structure, and two limiting clamping blocks 3071 are arranged on the circumference of the limiting clamping column 307 along the length direction of the limiting clamping column 307, and are matched with the first rotating clamping grooves 3035 and the second rotating clamping grooves 3045, and are correspondingly inserted into the first rotating sleeve 3034 and the second rotating sleeve 3044. It is worth noting that, in order to meet the angle adjustment requirement of the glass unit 200, the rotatable angle of the limiting clamping block 3071 in the first rotating clamping groove 3035 and the second rotating clamping groove 3045 is ±20°, and the size of the fan of the first rotating clamping groove 3035 and the second rotating clamping groove 3045 is designed in this way, compared with the existing open cavity slot engagement design, so that a larger adjustable angle range is realized.

[0078] In use, a pair of first fasteners 303 and second fasteners 304 are assembled in alignment, so that the first rotating sleeve 3034 at the end of the first fastener 303 is located between the two second rotating sleeves 3044 at the end of the second fastener 304 and is aligned up and down. Then the limiting clamping column 307 is inserted into the inner cavities of the first rotating sleeve 3034 and the second rotating sleeve 3044 from above, and the limiting clamping block 3071 is limited and installed in the second rotating clamping groove 3045 and the first rotating clamping groove 3035; then an inner hex mechanism screw is used to lock the limiting clamping column 307 from the top end and the bottom end of the limiting clamping column 307. The closed cavity type rotating mechanism composed of the first fastener 303, the second fastener 304 and the limiting clamping column 307 is more stable in stress and safer in structure system compared with the existing open cavity slot engagement design.

[0079] In addition, in order to overcome the problem that the existing open cavity type rotating engagement design cannot effectively control the over-rotation of the profile angle, which is not conducive to on-site construction and easily causes stress concentration between the structural adhesive and the glass due to angle rotation, causing safety hazards, a rotating mechanism design with controllable adjustment angle is provided, which mainly comprises a first fastener 303, a second fastener 304 and a limiting clamping column 307. By controlling the width of the rotating clamping groove on the first fastener 303 and the second fastener 304 and / or the width of the clamping block on the limiting clamping column 307, the rotating angle of the first fastener 303 relative to the second fastener 304 is controlled, and the purpose of meeting different glass angle installation requirements is achieved.

[0080] If necessary, the limiting clamping column 307 and the concentric axial profile formed by the first fastener 303 and the second fastener 304 can be angle-limited at every 5° interval to effectively control the profile angle over-rotation, facilitate on-site construction, and reduce the stress concentration between the structural adhesive and the glass caused by angle rotation, so that the structural adhesive is more stable under stress and the safety is improved.

[0081] Specifically, as shown in Figure 15 , the arc of the first rotating clamping groove 3035 on the first fastener 303 and the second rotating clamping groove 3045 on the second fastener 304 can be set to 45°, and the width of the limiting clamping block 3071 on the limiting clamping column 307 can be set to 35°, and the limiting clamping block 3071 can be angle-adjusted by ±10° in the rotating clamping groove.

[0082] For example, as shown in Figure 16 , the arc of the first rotating clamping groove 3035 on the first fastener 303 and the second rotating clamping groove 3045 on the second fastener 304 can be set to 50°, and the width of the limiting clamping block 3071 on the limiting clamping column 307 can be set to 30°, and the limiting clamping block 3071 can be angle-adjusted by ±10° in the rotating clamping groove.

[0083] In some embodiments, as shown in Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , the outer pressing plate fastener 400 mainly includes a first pressing plate 401, a second pressing plate 402, a limiting screw 404, a sawtooth column 403, and an adapter 405, the first pressing plate 401, the second pressing plate 402, the sawtooth column 403, and the adapter 405 are made of aluminum alloy, and the limiting screw 404 is an M5 stainless steel pan head machine screw.

[0084] Specifically, the first pressing plate 401 and the second pressing plate 402 are arranged in cooperation to form a point pressing plate structure of adjacent two glass units 200. The lower position of the inner side end of the first pressing plate 401 is provided with a first limiting sleeve 4011, and the first limiting sleeve 4011 is provided with a first circular sawtooth hole 4012 which is vertically through and side-opened. Correspondingly, the upper position of the inner side end of the second pressing plate 402 is provided with a second limiting sleeve 4021, and the second limiting sleeve 4021 is provided with a second circular sawtooth hole 4022 which is vertically through and side-opened.

[0085] In order to cooperate with the left and right two glass units 200 installed at an angle, the first pressing plate 401 and the second pressing plate 402 are installed and fixed at a certain angle. The sawtooth column 403 is a columnar structure with a plurality of gear racks equidistantly arranged along the length direction of the circumference. The upper and lower ends of the sawtooth column 403 are respectively engaged and buckled in the first circular sawtooth hole 4012 and the second circular sawtooth hole 4022.

[0086] During installation, the first pressing plate 401 and the second pressing plate 402 are tightly attached to the two side top glass units 200, and then the first limiting sleeve 4011 at the inner end of the first pressing plate 401 and the second limiting sleeve 4021 at the inner end of the second pressing plate 402 are respectively inserted above and below the sawtooth column 403. The first pressing plate 401 and the second pressing plate 402 are limitedly installed on the sawtooth column 403 by the engagement of the sawtooth column 403 and the limiting sleeve, and finally the limiting screws 404 are used to lock and fix the first pressing plate 401 and the second pressing plate 402 on the sawtooth column 403 from the upper and lower ends. The rotation between the first pressing plate 401 and the second pressing plate 402 is avoided, thereby achieving the limiting installation of the two glass units 200 on the inner side.
